Abstract

PURPOSE:To realize the work automatically inserting parts with high reliability, by constituting a device such that the parts having protrusions can be inserted while being depressed without causing the parts to be restricted except in the direction of insertion, in the case of the parts automatically inserted by a robot or the like. CONSTITUTION:First by the hand of a robot or the like, parts, in accuracy to an extent such that lead wires 1 are placed within a chamfered part 12 of fitting holes 3 drilled in a socket 4, are positioned and left being placed on the chamfered part 12. Next, after the hand of the robot or the like, which performed the handling, has been retreated, a retaining plate 14, having a rotary shaft 13 and a mechanism lifted through this shaft 13 further smoothing the contact surface with the parts 2 so that the parts 2 may be prevented from being restricted except in the direction of insertion, is rotated around the shaft 13 to be moved to a position directly above the parts 2, and then depressing the parts 2 to be inserted into the socket 4 by applying predetermined force of insertion. In such way, high reliable automatic insertion of the parts can be realized.

Description

[Detailed Description of the Invention] Technical field to which the invention pertains The present invention is directed to easily and reliably insert electronic components, etc., into a socket, etc., which has a hole that fits into the convex portion, by a special machine or a robot, etc. This relates to the insertion method.

Conventional technology When there are two or more work stations in an automatic machine that assembles parts using a robot, etc., when a predetermined work is completed at one work station, the robot's hand picks up the part and moves it to a predetermined position at the next station. Handling work is required to insert and set up parts.

Automatic insertion of parts by such handling requires a higher level of reliability than ever before, and it has been desired to provide an insertion method that can easily achieve this.

A conventional component insertion method will be described below with reference to FIG.

Conventionally, a plurality of Lee L!s as shown in the front view of FIG. 1 and the bottom view of FIG. 2 are created by a robot or the like. 5da-4f

Goods! When handling the part 1 and automatically inserting it into the socket 4 having the fitting hole 3 slightly larger than the diameter of the lead wire 1, the part 2 is first inserted into the socket 4 with a chuck installed at the tip of the hand 5 of a robot or the like. After holding, the purpose is to align the lead wire 1 and the central axes 7, 8 of the corresponding fitting hole 6.

The component 2 is moved to the top of the socket 4 and positioned so that the central axis 9 of the component 2 and the central axis 10 of the socket 4 coincide. Next, while holding the component 2 with the chuck 6, the hand 5 is lowered so that the central axes 9 and 10 do not shift, and the lead wire 1 of the component 2 is inserted into the fitting hole 6 of the socket 4 with a predetermined pressing force. insert.

In addition, as a substitute for the chuck 6 described above, there is also a method of vacuum suctioning the component 2 using a suction cup 11, as shown in FIG. 4, and inserting the component 2 in the same manner as the above method.

However, in the conventional method, the chuck 6 or the suction cup 1
Inclination of central axes 9 and 10 of component 2 and socket 4 that occurs when component 2 is held in step 1 9 Central axis 9 of component 2 and socket 4
, 10 and deformation of the lead wire 1, if the lead wire 1 and the center axes 7, 8 of the fitting hole 3 become misaligned, 2.
Since the component 2 is completely restrained by the chuck 6 or the suction cup 11, the flexibility of the lead wire 1 alone cannot absorb the misalignment of the central axes 7 and 8, leading to an accident in which the lead wire 1 is bent and crushed during insertion. Therefore, there is a drawback that a highly accurate positioning mechanism and holding mechanism are required to avoid this accident.

Furthermore, even if the high-precision mechanism described above is used, individual lead wires 1
Since it is impossible to deal with the deviation of the center axes 7 and 8 due to the inherent deformation of the holder, there is a drawback that accidents cannot be completely avoided.

Purpose of invention An object of the present invention is to manufacture parts by robots and the like.

The following is a margin.Structure of the Invention According to the present invention, fitting is facilitated in a method of automatically inserting a component having a convex portion into a socket or the like having a fitting hole that fits into the convex portion by handling by a robot or the like. Just enough to fit into the chamfered part of the ridge line of the mating hole.

An automatic component insertion method is obtained, which is characterized in that the component having the convex portion is positioned and installed in advance, and then the component having the convex portion is inserted while being pressed down without being restricted in any direction other than the insertion direction.

EMBODIMENT OF THE INVENTION The insertion procedure based on the embodiment of the present invention will be explained below with reference to FIGS. 5 to 7.

First, using a hand such as a robot, position the component 2 with such precision that the lead wire 1 can fit into the chamfered part 12 of the fitting hole 3 formed in the socket 4, and leave it on the chamfered part 12. .

After the hand 5 (FIG. 6) of the robot, etc. that performed the handling has retreated to a predetermined position.

■The press plate 14 has a shaft 1 through 1 and a heating mechanism, and has a smooth contact surface with the component 2 so as not to restrain the component 2 in any direction other than the insertion direction. Rotating shaft 16
, and then inserts the component 2 into the socket 4 by applying a predetermined insertion force.

In addition, the presser plate 14 used in this embodiment is attached to the robot's hand 5.
(FIG. 6).

In addition to the effects of the invention, if the component 2' is inserted without being restrained in any direction other than the insertion direction, the center axes 7 and 8 of the lead wire 1 and the fitting hole 3 may be misaligned due to one positioning error and the inherent deformation of the lead wire 1. Even if it occurs.

Since the component 2 is inserted while shifting laterally in the direction where the insertion resistance is reduced, that is, in the direction where the lead wire 1 and the central axes 7 and 8 of the fitting hole 3 coincide, highly reliable automatic component insertion is possible and even easier. It has the advantage that it can be easily realized with a simple positioning mechanism.
