Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mount manufacturing apparatus for supplying lead wires to a plurality of lead wire insertion holes formed in a mount head.

For example, a halogen light bulb used as a headlight for an automobile has a filament for a low beam and a filament for a running beam in its glass bulb. The sealing portion of this halogen light bulb does not use a glass flare stem that is used in general incandescent light bulbs, but is sealed by a crush seal called a so-called pinch seal.
Therefore, in this type of halogen light bulb, it is necessary to align a total of four lead wires connected to each filament on the same straight line on a single crushing sealing surface for crushing sealing. Moreover, since the above-mentioned headlamp is required to have strict light distribution characteristics, it is necessary to define the mutual positions of the filaments within the bulb with high precision.

By the way, conventionally, in order to align four lead wires, a two-core wire has four lead insertion holes on the same straight line and has chucks for individually fixing the lead wires inserted into the insertion holes. A method is used in which a mount head is prepared, the lead wires are inserted one by one into the insertion holes of the mount head, and then fixed with chucks to align them on the same straight line. However, in this case, most of the process of attaching the lead wire to the mount head has traditionally been done manually by humans, resulting in extremely poor work efficiency and the problem of quantity differences associated with automated manufacturing. There are some problems such as making it unsuitable. Moreover, since it is a human operation, the reliability is low, and therefore there are many variations in the mounting posture of the lead wires, which tends to reduce product accuracy.

The present invention was made based on the above circumstances, and its purpose is to enable the lead wire to be reliably and automatically attached to the mount head, and to maintain a constant attachment posture of the lead wire. In addition, it is an object of the present invention to provide a mount manufacturing device that enables automatic assembly of the mount.

That is, in order to achieve the above object, the present invention
The mount head supported by the head holder is provided with a guide section that serves as a reference for positioning, and a hopper support is provided above the mount head that can move up and down with respect to the mount head. The wire guide is suspended via a shaped bellows so that it can move freely in the vertical and XY directions.
This wire guide is provided with a supply path that is aligned with the lead wire insertion hole of the mount head and supplies the lead wire from the lead wire supply hopper supported by the hopper support, and a guide provided in the mount head. A position regulating body that engages with the guide part is provided, and the wire guide follows the deformation of the bellows by bringing the wire guide and the mount head close to each other and engaging the position regulating body with the guide part.
It is characterized in that it is moved in the XY directions to align the supply path with the lead wire insertion hole.

The present invention will be explained below based on an embodiment shown in the drawings.

First, the structure of the mount head 1 shown in FIG. 1 will be described. Reference numeral 2 is a rectangular box-shaped head body, and the lower part of the head body 2 is provided with hooks 3, 3 that protrude from both sides. It is being As a preferred example, the upper part of the head body 2 is formed into a truncated cone shape that tapers upwardly, and the upper surface of the head body 2 that is connected to the conical surface 4 is formed horizontally. On the upper surface of the head body 2, four lead wire insertion holes 5a, 5b and 5c, 5d are arranged in parallel along the same straight line with a predetermined interval. 5b, 5c, and 5d pass through the inside of the head body 2 along the vertical direction. Note that an insertion hole 6 for inserting an exhaust pipe is formed penetratingly between the lead wire insertion holes 5b and 5c. Further, a recess 7 that opens on one side is provided in the head main body 2, and within this recess 7 are four chuck claws 8a,
8b, 8c, and 8d are attached. Although not shown in detail, the chuck claws 8a, 8b, 8c, and 8d have one end located in the opening of the recess 7, and the other end located in the lead wire insertion holes 5a, 5b, 5c, and 5d in the head body 2. These other ends and the insertion holes 5a, 5
The lead wires 9a, 9b and 9c, 9d inserted between the inner surfaces of the lead wires 9b, 5c, and 5d are individually checked. In the upper part of one side of the mount head 1 where the recess 7 is opened, a lead wire insertion hole 5 is provided.
A guide groove 10 is cut along a direction perpendicular to the parallel direction of the wires a, 5b, 5c, and 5d, and lead wire insertion holes 5a, 5b, and 5c are formed on the side opposite to this one side. A guide surface 11 is formed parallel to the parallel direction 5d.

However, the mount head 1 with this structure
is attached via a head holder 13 to a table 12 which is intermittently rotated one pitch at a time in a horizontal plane at a predetermined index. That is, a plurality of head holders 13 for supporting the mount head 1 are fixed at equal intervals in the circumferential direction on the peripheral edge of the table 12, and the hook portion 3 of the mount head 1 is attached to the tip of the head holder 13. , 3 are locked. In this case, the mount head 1 has one side where the chuck claws 8a, 8b and 8c, 8d are located facing outward, and the lead wire insertion holes 5a, 5b and 5c, 5.
It is designed to be fixed in a position with d facing up and down. In addition, mount head 1 is table 1.
At the supply position set around 2,
is supplied onto the head holder 13 and the table 1
As the head holder 2 rotates, the head holder 13 is moved to a removal position that is circumferentially distant from the above-mentioned position, and is then taken out from above the head holder 13. Further, between the supply position and the removal position, a first lead wire insertion position 101 and a second lead wire insertion position 102 are set in this order, and both of these positions 101,
At 102, a manufacturing apparatus according to the present invention is arranged. Reference numeral 14 is its base, which is located outside the table 12. On this base 14, a pair of cylinders 15 such as air cylinders and hydraulic cylinders,
15 are arranged vertically along the vertical direction, and a bracket 17 is attached between the tips of rods 16, 16 that project upward from these cylinders 15, 15. A hopper support 18 is connected to the upper part of the bracket 17, and the hopper support 18 is connected to the mount heads 1, 1 located at the first and second lead wire insertion positions 101, 102. It is now possible to move up and down. The hopper support 18 has lead wire insertion holes 5a, 5 of the mount holder 1.
A pair of supply mechanisms 19 for supplying lead wires 9a, 9b and 9c, 9d to the bellies 5c, 5d
and 20 are installed. One supply mechanism 1
9 is for supplying lead wires 9a and 9b to the lead wire insertion holes 5a and 5b of the mount holder 1 in the first lead wire insertion position 101, and the other supply mechanism 20 is in the second lead wire insertion position. This is for supplying the lead wires 9c and 9d to the lead wire insertion holes 5c and 5d of the mount holder 1 located at 102, and since both of these supply mechanisms 19 and 20 have the same structure, one of the supply mechanisms 19 is shown as a representative. I will explain.

A press plate 21 is provided on the front end surface of the hopper support 18, and one end of the press plate 21 is pivotally supported on one side of the front end surface of the hopper support 18 via a pin 22. A butterfly bolt 23 is fitted into the other end of the presser plate 21, and the tip of the butterfly bolt 23 is screwed onto the front end surface of the hopper support 18. Therefore, when the butterfly bolt 23 is tightened, the presser plate 21 is brought into contact with the front end surface of the hopper support 18. In addition, semicircular fitting recesses 24 and 25 are formed on the abutting surfaces of the hopper support 18 and the holding plate 21, and these fitting recesses 24 and 25 are opposed to each other to form a circular fitting.

This support ring 27 has a groove 28 continuous in the circumferential direction on its outer peripheral surface, and this groove 28 is engaged with the inner surface of the mounting hole 26 . That is, after the support ring 27 positions the groove 28 between the fitting recesses 24 and 25, the wing bolt 2 is inserted into the support ring 27.
These recesses 24, 25 by screwing in
This clamping pressure causes the hopper support 18 to
It is becoming fixed. The upper end of a metal bellows 29 is coaxially welded to the lower surface of the support ring 27, and the movable body 30 is welded substantially coaxially to the lower end of this bellows 29. Therefore, this movable body 30 supports the support ring 2
7, in other words, the hopper support 18

The movable body 30 has a disk-shaped support flange 31 welded to the bellows 29 on its upper surface, and a mounting recess 32 is formed in the center of the support flange 31. A through hole 33 is formed at the bottom of the mounting recess 32, and a bracket 34 is fitted into the through hole 33. A wire guide holder 35 is fitted into the mounting recess 32 and fixed with wing bolts 36 to prevent it from coming off. The upper part of the wire guide holder 35 has a cylindrical shape and extends upward, and this extension part 37 is inserted through the bellows 29 in the vertical direction. A mounting hole 38 is formed through the wire guide holder 35 in the vertical direction, and the upper end of the mounting hole 38 opens on the upper surface of the extension part 37, and the lower end tapers downward. The wire guide holder 35 has a shape and is opened on the lower surface of the wire guide holder 35 . A wire guide 39 is inserted into this attachment hole 38. This wire guide 39 has a two-part structure formed by a pair of guide halves 40 and 41 that abut each other in the radial direction.The upper end of this wire guide 39 is led out from the upper end opening of the mounting hole 38, and the lower end side Mounting hole 38
It is narrowed into a small diameter that tapers along the shape of the
This small diameter portion 42 passes through the inside of the bracket 34 and is led out to the lower surface of the bracket 34. A gap 43 that continues in the longitudinal direction is formed between the abutting surfaces of the guide halves 40 and 41, and both ends of this abutting surface are inclined obliquely along the longitudinal direction. Insertion spaces 44, 44, which are connected to the space 43 and have a generally fan-shaped cross section, are formed between the ends of the abutting surfaces of the guide halves 40, 41.
Furthermore, a protrusion 45 is provided continuously in the longitudinal direction at the center of the abutting surface of one guide half 40, and the tip of the protrusion 45 is fitted into the abutting surface of the other guide half 41. A concave groove 46 is provided. Therefore, the above-mentioned protrusion 45 has the above-mentioned interval 43
A pair of supply paths 47 and 48 are formed in the wire guide 39 by dividing the wire guide 39 in the width direction. Furthermore, guide walls 49, 49 are protruded from the lower end of the abutting surface of the other guide half 41 on both sides thereof, and these guide walls 49, 49 are provided with the abutting surface of the one guide half 40. It has a tapered shape that bulges inward as it goes downward. For this reason, the lower ends of the supply channels 47, 48 are tapered, and the lower end openings are opposed to the openings of the lead wire insertion holes 5a, 5b of the mount head 1. Furthermore, a position regulating plate 50 is attached to one side of the movable body 30 so as to protrude downward, and as the movable plate 30 descends, the position regulating plate 50 touches the guide surface 11 of the mount head 1. It is designed to make a sliding contact. Further, a positioning pin 51 is protruded from the lower surface of the movable body 30, and the base end of this positioning pin 51 is inserted into the inner part of the guide groove 10 of the mount head 1 as the movable body 30 moves up and down. It is tightly fitted in a removable manner and has a tapered tip.

On the other hand, at the upper end of the wire guide holder 35,
A guide cap 52 is provided to cover the upper end of the wire guide 39 led out from here, and the upper surface of the guide cap 52 has through-holes 53 and 53 connected to the supply channels 47 and 48 in the wire guide 39 respectively.
has been established. And these through holes 53, 53
Hoppers 54, 54 are removably fitted and connected to the hoppers 54 and 54, respectively. The hoppers 54, 54 have a shape that becomes wider as they move upward, and the support ring 27
Lead wire insertion nozzles 55, 55 are inserted into the upper end opening.

The base 14 also has a chuck opening/closing jaw 5.
6 is provided, and this chuck opening/closing jaw 5
6 is directly opposed to one end of the chuck pawls 8a, 8b of the mount head 1, and can be moved forward and backward relative to the chuck pawls 8a, 8b by an air cylinder 57 or the like. Further, a positioning plate 58 is arranged below the mount head 1, and this positioning plate 58 is located directly below the lead wire insertion holes 5a, 5b.
The mounting head 1 is moved up and down by a cylinder 59 such as an air cylinder to a position where it comes into contact with the lower surface of the mount head 1 or is a predetermined distance away from the lower surface.

Next, the operation of the above configuration will be explained.

When the mount head 1 fixed on the head holder 13 is sent to the first lead wire insertion position 101, the table 12 is stopped, and the positioning plate 58 is first raised and the mount head 1 is moved to the first lead wire insertion position 101.
The chuck claws 8a, 8
b is advanced, and thereby the chuck claws 8a, 8
One end of b is pushed in and the opening operation is performed. Subsequently, the rods 16, 16 are operated in the retracting direction by the cylinders 15, 15 or the cam drive, and the feeding mechanism 19 is lowered together with the hopper support 18.
Then, the movable body 30 approaches the upper surface of the mount holder 1, and in this process, the lower end of the position regulating plate 50 comes into contact with the conical surface 4 of the mount head 1. In this case, since the movable body 30 is connected to the support ring 27 fixed to the hopper support 18 side via the bellows 29, it is in a state where it can move freely within a certain range in any direction. ,
Based on the contact between the position regulating plate 50 and the mount head 1, the movable body 30 is arranged so that the position regulating plate 50 can slide against the guide surface 11 of the mount head 1. In other words, the movable body 30 is guided with respect to the guide surface 11. It moves along a direction perpendicular to the parallel direction of the wire insertion holes 5a, 5b and 5c, 5d. Also, at the same time as the position regulating plate 50 contacts, the positioning pin 51
When the tip of the movable body 30 enters the guide groove 10 of the mount head 1 and the inner surface of the guide groove 10 comes into contact with the outer peripheral surface of the proximal end as the positioning pin 51 descends, the movable body 30 engages the positioning pin 51 and guide. It moves based on contact with the groove 10. When the base end of the positioning pin 51 is tightly fitted into the inner part of the guide groove 10, the positioning pin 51 and the position regulating plate 50 are connected to the guide surface 11 of the mount head 1 and The opposite side surface is clamped, and thus the position of the movable body 30 in the Y direction that is perpendicular to the parallel direction of the lead wire insertion holes 5a, 5b and 5c, 5d is defined. At the same time, based on the fitting between the guide groove 10 and the positioning pin 51, the movable body 30 moves into the lead wire insertion hole 5.
The positions in the X direction along the parallel direction of a, 5b and 5c, 5d are defined, and by positioning in two directions orthogonal to each other, the lower end openings of the supply paths 47 and 48 are aligned with the lead wire insertion hole 5 of the mount holder 1.
A and 5b are matched against each other. In a state where the movable body 30 is positioned in this way,
When the bellows 29 is contracted, the lower surface of the bracket 34 comes into close contact with the upper surface of the mount head 1, and the supply mechanism 1
9 the entire descent is stopped. Next hoppa 54,5
Lead wires 9a, 9b are dropped into the inside of the lead wire 4 through lead wire insertion nozzles 55,55. These lead wires 9a, 9b slide into the supply channels 47, 48 and are introduced into the lead wire insertion holes 5a, 5b from the lower end openings, and when the insertion tips abut the positioning plate 58, the insertion holes 5a, 5b It is stopped within. When the lead wires 9a, 9b are supplied in this manner, the chuck opening/closing jaw 56 returns to the standby position, and the lead wires 9a, 9b are chucked by the chuck claws 8a, 8b. Subsequently, the positioning plate 58 is lowered, and the entire supply mechanism 19 is raised, and the positioning plate 50 and positioning pin 51 are removed from the guide surface 11 and guide groove 10 of the mount head 1, and the lead wires 9a, 9b are removed. Supply is complete.

When the supply of the lead wires 9a and 9b is completed in this way, the table 12 is rotated one pitch, a new mount head 1 is positioned at the first lead wire insertion position 101, and the same operation as described above is repeated. At the same time, the mounting head 1 is mounted with the two lead wires 9a and 9b.
is sent to the second lead wire insertion position 102. And this second lead wire insertion position 1
02, the lead wires 9c and 9d are attached to the empty lead wire insertion holes 5c and 5d via the supply mechanism 20 in the same manner as described above, and as a result, the mount head 1
has four lead wires 9a, 9b and 9c, 9d.
will be arranged.

After this, a filament coil is temporarily installed between the tips of the lead wires 9a, 9b and 9c, 9d to form a mount, and a glass bulb is placed on this mount, and a mount head 1 is placed inside this bulb. An exhaust pipe is inserted through the insertion hole 6 . Then, the opening of the bulb is crushed and sealed to complete the halogen bulb, and the halogen bulb is taken out from above the head 13 together with the mounting head 1 in the removal position.

According to such a manufacturing device, the hoppers 54, 5
4 and a movable body 30 equipped with a wire guide 39
is connected to the support ring 27 via the bellows 29, so that it can move within a certain range with respect to the mount head 1, and in the process of lowering the movable body 30, it can move in the X and Y directions perpendicular to each other with the mount head 1 as a reference. Since it is moved, the supply channels 47 and 48 in the wire guide 39 are connected to the insertion holes 5a, 5b and 5c of the mount head 1.
5d can be aligned with high precision. Therefore, the leads 9a, 9b and 9
c, 9d are reliably and automatically inserted into the lead wire insertion hole 5.
a, 5b, 5c, and 5d, the mounting posture of the lead wires 5a, 5b, 5c, and 5d can be kept constant, and each process of manufacturing the mount can be arranged in a line to create a series of equipment. It can be mechanized as As a result, significant labor savings in light bulb manufacturing can be achieved, and manufacturing efficiency is greatly improved.

Further, the wire guide 39 is removed from the hopper support 18 together with the support ring 27 by opening the presser plate 21, and then loosening the wing bolt 36 and removing the hopper 5 from the hopper support 18.
If you pull up 4,54, this hopper 5
4, 54 and the wire guide holder 35 from the movable body 30, and by separating the hoppers 54, 54 and the wire guide holder 35, the wire guide holder 35 can be easily taken out as a single unit. Moreover, this wire guide 39 has a pair of guide halves 40,
41, and the supply passages 47, 48 are formed between the abutting surfaces of these guide halves 40, 41, so if the guide halves 40, 41 are separated, the inside of the supply passages 47, 48 can be opened. It can be released to the outside. Therefore, from the above, even if the lead wires 9a, 9b and 9c, 9d should become stuck in the wire guide 39, these lead wires,
9a, 9b and 9c, 9d can be easily eliminated,
This has the advantage that maintenance and inspection can be easily performed.

In the above embodiment, a case has been described in which four lead wires are arranged in parallel, but the same can be applied to a case in which two lead wires are arranged in parallel.

Further, in the above embodiment, the movable body is aligned with the mount head using the position regulating plate and the positioning pin. A positioning recess may be formed on the lower surface of the movable body so as to fit tightly into the positioning portion, and positioning in the X and Y directions may be performed using this one recess.

In the present invention described in detail above, the mount head is provided with a guide portion that serves as a reference for positioning in the XY direction with respect to the parallel direction of the lead wire insertion holes of the mount head, and the guide portion is provided so as to move up and down relative to the upper part of the mount head. A wire guide is movably suspended relative to the mount head via a bellows on a hopper support provided in a movable manner, and this wire guide is provided with a supply path for supplying lead wires and is latched to the guide portion. By providing a position regulating body that moves the wire guide and the mount head relatively close to each other and locking the position regulating body to the guide portion, the wire guide is moved to follow the deformation of the bellows and the wire guide is moved. The supply path is aligned with the lead wire insertion hole. According to this, the lead wire can be guided into the lead wire insertion hole reliably and automatically, and the work of attaching the lead wire, which has conventionally been done manually, can be automated. Therefore, there is no risk that the lead wire attachment position will vary.
In addition to improving product precision, each process of mount manufacturing can be arranged in a line and mechanized as a series of devices, which not only significantly saves labor in light bulb manufacturing but also greatly improves manufacturing efficiency.
