Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic component insertion device that automatically attaches an electronic component having an axial lead wire to a predetermined hole of a printed circuit board.

Conventionally, in this type of component insertion device, tapes on which electronic components are aligned are placed on a movable table in parallel in one direction, and a board on an X-Y table is provided so as to be movable on a flat surface. It was structured. Therefore, when inserting a predetermined component onto a board, the moving table is first moved linearly so that the tape carrying the predetermined component is near the position of the insertion head, and then the insertion head separates the component from the tape. At the same time, lead wires were formed and then inserted into predetermined positions on the board. That is, since the moving table on which the tape is placed moves linearly, a large space is required in the longitudinal direction of the machine, and it is difficult to see the entire machine, which is disadvantageous in terms of maintenance. In other words, when managing multiple machines, it is difficult to grasp the overall situation, and the number of machines that one person can manage is limited by the size of the machines in the same space. Therefore, extra personnel were required to manage a large number of machines.
In addition, if a line system is used, problems may arise such as only one machine can fit in a place where two machines are required in the limited line space, and the line configuration may need to be reviewed to improve production efficiency. It was hot. Therefore, it was necessary to reduce the space.

The present invention solves the above-mentioned problems and provides a device whose machine length is reduced to one-third or less of that of conventional devices and whose occupied area is reduced to one-half or less.

3. The operation of the insertion shaft 101 and the cutter unit 9 will be explained using FIGS. 14 to 18.

As shown in FIG. 14, at the origin (starting position 0°), the cutter unit 9 is placed in a position where there is no risk of collision with the parts cassette 1 at the set position due to the rotation of the circular table 8 (downward). to
30° to 60° tilted). As a result, the insertion plate cam 1
10 begins to rotate, giving rise to the drive shaft 130 to the top dead center of the cam. As the drive shaft 103 rises, the insertion shaft 101 also rises at the same time since it is locked by the stepped portion 103' of the drive shaft.

Due to this rise, the slide rack 114 that meshes with the shaft pinion 112, which is supported by the tip flanges 113, 113' of the insertion shaft, comes into contact with the lower surface 102' of the head body, so that the shaft pinion 112 is rotated counterclockwise. A rotation in the direction (arrow D) is given,
As a result, the cutter unit 9 is rotated counterclockwise and is set to be in a horizontal state at the top dead center of the insertion plate cam 110. If this position is defined as cutting position A and the positional relationship between parts cassette 1 and cutter unit 9 is as shown in FIGS. 10 and 11, parts 3 sent from parts cassette 1 to supply line XX As mentioned above, air is sent to the cylinder 76 to separate the tape from the tape and hold it (first
(See Figures 2, 13, and 16). When the part is held in the cutter unit 9, the drive shaft 103 begins to descend.
At the same time, the insertion shaft 101 connected by the steel ball 161 starts to descend.

When the slide rack 114 starts to descend, it is constantly pushed upward by the built-in compression spring 116 as the slide rack 114 moves upward, so that it is pushed up relatively, and the shafted pinion 112 that is meshing with the rack moves clockwise. Direction (arrow B direction)
As a result, the cutter unit main body 75 also rotates clockwise, and the legs (conductor wires) 2a and 2b of the component are placed above the printed circuit board, and the rear end 75' of the cutter unit main body 75 is placed against the stopper 128 and inserted. Be ready. From here, a certain amount a in a vertical state

0' can be taken.

Furthermore, even after the insertion shaft 101 stops descending, the drive shaft 10
3 moves down independently, but the slider 119 connected with the pin 121 also moves into the groove 1 of the flange 113'.
Descend along 20. Following this downward stroke, the regulating surface 122' of the regulating block 122 attached to the slider 119 immediately comes into contact with the regulating lever 126, locking the rotation of the cutter unit body 75, and further, the cam surface 123' of the release cam 123 The holding lever 89 is rotated in the direction of arrow C (see FIG. 13A) via the roller 94 of the arm shaft 90, and the clamped part 3 is released (see FIGS. 12 and 13). At that point vault 14
1 comes into contact with the seat surface 105' of the head arm 105 and stops the lowering of the drive shaft 103.

When the holding lever 89 releases the component 3, the pusher 82 pushes the component downward by the force of the compression spring 83 as described above, and the (conductor wire) guide 80 of the molding element, which has already been guided to the insertion destination of the inserted printed circuit board, The lead wires 2a and 2b of the component 3 are guided and inserted through 80'.

In order to ensure the extrusion of part 3, drive shaft 1
The rear end 81' of the rod 81 is pushed down until the insertion is completed by a pin 140 which is rotatably supported at the tip of the rod 81, but the compression spring 138 is used to prevent deformation of the part due to variations in the diameter of the part.

When the insertion is completed and the drive shaft 103 reaches the bottom dead center, the air sent to the cylinder 76 of the cutter unit body 75 is cut off and the piston 69 is returned to its original state.

After passing the bottom dead center, only the drive shaft 103 begins to rise, and the stepped portion 103' performs the reverse operation when descending, and then the groove 162' of the guide cylinder 162 moves upward.
The steel ball 161 that is engaged with the drive shaft 103 is fitted into the spherical recess 103″, and immediately after that, the stepped portion 1
At 03', the insertion shaft 101 is locked and they begin to rise as one. From here, the slide rack 114 comes into contact with the lower surface 102' of the insertion head body again, and the pinion with shaft 112 and the cutter unit body 75 rotate counterclockwise and return to the original 0° position.

The profile of the feed cam 137 is set so as to adapt to the above-described insertion operation and reliably restrict the feed operation of the component 3.

To convert the part 3 to the Z-Z line, the cutter unit 9 performs cutting, forming, and gripping operations at the cutting position A of the part 3, and when the drive shaft 103 begins to descend, the rotary plate cam 147 moves through the cam follower 146. By activating the link 142 and engaging as described above, the insertion shaft 101 and the drive shaft 103 are moved in the 90° direction A (the 20th direction).

First, at the starting position (0° position in the table),
The board moving unit 11 moves the printed circuit board 12 set in advance
It is stopped at the position. Further, the parts 3 to be inserted are prepared one pitch before the cutting position A (FIG. 14) by the parts cassette 1 and the rotary table 8. Further, the cutter unit 9 is waiting at the home position with the cylinder OFF. Subsequently, when the next instruction to start insertion is issued, the base moving unit 11
starts positioning the printed circuit board 12 so that the component 3 at position B is inserted into the hole into which it is to be inserted.
Further, the cutter unit 9 immediately moves to the B position, and at the same time, the feed block 130 of the tape feed shaft 129 descends, and the lever 18 of the parts cassette 1 moves downward.
is pushed through roller 19 and the tape is fed by the previously described operation so that the part is always on the X--X line (FIG. 10).

At this point, the cutter unit main body 75 is operated as described above to cut and mold the part 3, and the part 3 is ready for insertion.

When inserting a Z-Z line component, a rotation command is issued to the insertion head section 10 from the drive control section 13, and the cutter unit main body 75 enters the insertion position on the drive shaft 103 by the above-described operation, so it is necessary to start lowering. While entering the insertion position, the drive shaft 103 is rotated along the Z-Z line to complete the insertion position.

The tip of cutter unit 9 is attached to parts cassette 1.
When the circular table 8 passes through the collision danger area, it starts moving and prepares the next part to be inserted.

Since the positioning of the board moving table 11 has been completed up to this point, the insertion head 10 starts to descend and moves to the insertion operation, and the component is inserted into the corresponding hole of the printed circuit board by the above-mentioned insertion operation.

Next, the cutter unit 9 returns to the origin position, but if the drive shaft 103 is on the Z-Z line, the cutter unit 9 returns to the origin position on the X-X line according to the profile of the rotary plate cam 147 while returning to the origin. do.

In this way, one cycle of component insertion is performed by waiting until the next insertion command is issued.

As described above, according to the present invention, since the entire device is configured in a small space, it is easy to manage the device.
This has a great effect on line production by combining with other devices.
