[Industrial application field]

The present invention relates to an automatic mounting machine that automatically mounts a flexible vibration-proof rubber having a double brim portion by fitting the double brim portion into a hole of a body to be mounted.

In a CD player or the like, an anti-vibration rubber is provided between the equipment casing and the internal chassis so that external vibration is not transmitted to the internal main part. Since this anti-vibration rubber is flexible, it is difficult to attach it to the hole of the chassis (attached body).

[Conventional technology]

FIG. 8 is an example of an oil damper used as the above-mentioned vibration-proof rubber, (a) is a plan view and (b) is a sectional view.
The anti-vibration rubber 30 has double collars 32 and 33 on the head of the main body 31, and is sometimes called an E spacer because of its shape.
The inside of the main body 31 is a cavity, and oil 34 is filled therein. The brim portions 32 and 33 are mounted in the holes 41 of the sheet metal (chassis in this example) 40 as shown in FIG. A recess 35 is formed in the bottom of the main body 31, and a pin or the like erected on the bottom of the housing is fitted therein. With this, the sheet metal 41 is supported on the bottom of the housing and is supported via the plurality of anti-vibration rubbers, so that vibration on the housing side is difficult to be transmitted to the sheet metal 41.

FIG. 9 shows a process of mounting the above-mentioned anti-vibration rubber 30 on the sheet metal 40. First, as shown in (a), the main body 31 is inserted into the hole 41 of the sheet metal 40, and the whole is supported by the lower brim portion 33 and hung down. Since the hole 41 of the sheet metal 40 is formed to have a smaller diameter than the flange portions 32 and 33, in order to expose the lower flange portion 33 to the lower side of the sheet metal 40, as shown in FIGS. Are pulled out in order in four directions, and the brim portions 33 are partially projected downward from the holes 41, and finally the state of (d) attachment is completed. In this state, the brim portion 32 is above the sheet metal 40, and the brim portion 33 is the sheet metal 40.
Since it is on the lower side, the whole rubber plate 30 is firmly attached with the sheet metal 40.

[Problems to be solved by the invention] Conventionally, all the mounting work shown in FIG. 9 is manually performed, but in particular, as shown in (b) and (c), the flexible (funyafunya) body 31 is pinched with a fingertip and pulled. The work of pushing and pushing requires a lot of power, and the inefficiency is noticeable when many are attached. Further, when the lower brim portion 33 does not pass through the hole 41 at all, the lower portion of the antivibration rubber is strongly pulled, and the antivibration rubber may be broken and the oil inside may come out.

In particular, the present invention automates the work of (b) and (c),
It is intended to improve the work efficiency when mounting the anti-vibration rubber.

[Means for Solving the Problems]

According to the present invention, the main body of a vibration-proof rubber having a double head portion of a flexible main body is inserted into a hole having a diameter smaller than that of the head portion of the mounted body while deforming the lower head portion. In a vibration isolating rubber automatic mounting machine that is mounted by passing through the hole, a support mechanism for supporting the mounted body, a chuck portion for gripping the main body of the vibration damping rubber hanging from the hole of the mounted body, A first base that mounts a chuck unit and is movable in the Y direction;
It is configured to include a second base that is movable in the X direction, and a flexible body having a double collar portion on the head of the body is made of an anti-vibration rubber. In a vibration-damping rubber automatic mounting machine that is inserted into a hole having a diameter smaller than that of the brim and passes through the hole while deforming the lower brim, a support mechanism for supporting the mounted body and the mounted body A rod-shaped pressing piece that presses the body of the anti-vibration rubber hanging from the hole in the body, a first base that mounts the pressing piece and is movable in the Y direction, and the first base,
And a second base movable in the direction.

[Action]

Even in the present invention, the stand-by state shown in FIG. 9 (a) is manually performed. Then, a step of bending the main body 31 to expose the lower brim portion 33 to the lower side of the hole 41 part by part as shown in FIGS.
This is automatically performed by a first base that moves in the Y direction and a second base that mounts the first base and moves in the X direction.

The means for bending the main body 31 can be realized by a chuck portion that holds the main body 31 or a rod-shaped pressing portion that pushes the main body 31, and the former can be pushed as well as pulled. The latter only pushes.

An air cylinder or the like may be used as a drive source for the first and second bases.

〔Example〕

FIG. 1 is a configuration diagram showing an embodiment of the present invention, (a) is a plan view and (b) is a side view. In the figure, 3 is the third lowest layer
At the base of this, this is fixed. Reference numeral 2 denotes a second base mounted on the second base, which is driven by the cylinders 15 and 16 and reciprocates in the X direction. Reference numeral 1 is a first base placed on the second base 2 and is made Y by the cylinders 13 and 14.
Reciprocates in the direction. Four chuck parts 20 are provided on the first base 1, and each of them can hold an E spacer (vibration isolating rubber) 30. The cylinders 11 and 2 are for holding the four E spacers 30 at the same time by these chuck portions 20. (See below).

There is a circular hole 51 in the center of the first base 1, through which a column 52 standing upright from the third base 3 passes, and a sheet metal mounting table (support mechanism) 53 is attached to the head of the first base 1. It is fixed in contact with 1. Two pins 54 are provided upright on the end of the mounting table 53 and are used for positioning the sheet metal. That is, taking the sheet metal 40 of FIG. 7 as an example, a hole 42 corresponding to the pin 54 is previously formed therein, and the pin 54 is formed therein.
Insert. FIG. 2 is a block diagram showing the first base 1 alone.

The chuck portion 20 has a pair of claws 21 which are normally opened by springs 22 (see FIG. 3), and a wedge-shaped pusher 23 is provided between the cylinders 11 and 12.
When is pushed forward to push open the space between the rollers 24, the tab 21 is closed around the fulcrum 25 and the E spacer 30 (below the brim 33 of the main body 31) is gripped. FIG. 3 is this state diagram, in which (a) is a standby state in which the tabs 21 are opened, and (b) is a chuck state in which the tabs 21 are closed.

Reference numeral 30 in FIG. 1 shows the E spacer in the state of FIG. 9 (a) hanging from the hole 41 of the sheet metal 40 placed on the mounting table 53.

The main body 31 of the E spacer 30 in this state is gripped by the chuck portion 20, the first base 1 is moved (reciprocated) in the Y direction by the cylinders 13, 14, and then the second base 2 is moved by the cylinders 15, 16. By moving (reciprocating) in the X direction, the work shown in FIGS. 9B and 9C is automatically performed. This order may be reversed. X, Y
The moving range in the direction is within the range of the difference between the diameter of the hole 51 and the diameter of the support column 52.

Since the chuck part 20 described above grips the main body 31 of the anti-vibration rubber 30 from both sides, one of the claws of the chuck part abuts the protruding part of the sheet metal (chassis) depending on the moving direction.
It may be impossible to move further. Further, in the method of gripping the E spacer from both sides (Y direction in FIG. 1), it is easy to pass through a part of the hole 41 head portion 33 in the Y direction, but it is difficult to pass in the X direction orthogonal to the hole 41.
An effective operation to pass a part of the hole 41 head portion 33 is to push the portion directly below the head portion 33 horizontally from one side as much as possible,
As a result, the pressing portion is dented, and the brim portion 33 in the vicinity thereof is bent downward while denting and passes through the hole 41. If this operation is performed from the front, back, left and right, the entire brim portion 33 passes through the hole 41. No action is required to pull the E-spacer down or diagonally down.

FIG. 4 is a perspective view of another embodiment of the present invention in consideration of these points. This example also has the same bases 1 to 3 as in FIG. 1, but FIG. 4 mainly shows the portion of the first base 1. In this example, as shown in FIG. 5, the means for bending the anti-vibration rubber 30 is replaced with four rod-shaped pressing pieces 61 to 64, the two outer pressing pieces 61 and 62 are fixed to the base 1, and the inner two pieces are fixed. The pressing pieces 63, 64 can be moved back and forth through holes 65, 66 provided in the base 1. Reference numeral 17 is a cylinder that changes the amount of protrusion of the pressing pieces 63 and 64.

When the second base 2 is moved in the X direction, the left and right pressing pieces 61 and 64 shown in FIG.
Used to push in the direction. On the other hand, the upper and lower pressing pieces 6
Reference numerals 2 and 63 are also used to push the main body 31 of the rubber cushion 30 in the Y direction when moving the first base 1 in the Y direction.
FIG. 6 (b) shows the pressing piece 62 by moving the base 1 in the Y direction.
The state is shown in which the main body 31 is pushed by and a part of the brim portion 33 is passed under the sheet metal 40. By doing this in four directions, the mounted state of (c) is obtained, and (a) shows the sheet metal 40 and the anti-vibration rubber 30.
It is in the standby state just inserted.

The reason why the inner pressing pieces 63, 64 are moved back and forth is to avoid collision with the sheet metal 40 when the bases 1, 2 are moved. In addition, each pressing piece
The heads of 61 to 64 are formed in a spherical shape in order not to damage the vibration-proof rubber 30 and to locally push the area directly under the brim portion 33 to easily turn the brim portion.
