Description

[Detailed Description of the Invention] The present invention relates to a component press-fitting device for assembling components by press-fitting components such as terminals of electrical components onto insertion pins fixed to a board.

Up until now, it has been difficult to mechanize the work of press-fitting the terminal into the insertion pin because the press-fit parts to be handled are small and high press-fit precision is required. Therefore, the current situation is that workers use installation jigs to press-fit components entirely manually. For this reason, the efficiency of parts assembly and attachment work was poor, and automation was desired. The present invention has been devised for the above reasons.

Hereinafter, details of the present invention will be explained with reference to drawings showing an embodiment of the present invention. FIG. 1 is a front sectional view of the device of the present invention. In this figure, terminals (hereinafter referred to as parts), which are press-molded press-fit parts, are carried one by one in a line through a transport pipe 1 to a charging guide 2 by an alignment/separation device (not shown). Since the press-fitting parts pitch required for the apparatus according to the embodiment of the present invention is set to be very narrow, simply arranging the transport pipes 1 cannot achieve the predetermined pitch interval due to the thickness of the transport pipes. Therefore,
In this embodiment, a charging guide 2 is provided, and a desired pitch is obtained at the lower end by cutting the charging path 3, which is connected to the transport pipe 1 at the upper end, downward and narrowing the pitch. A conveying groove 4 is provided below the charging guide 2 and is formed to be slightly deeper than the height of the component.
A slidably positioned transport rod 5 is provided in the transport groove 4.

A push-up tool 24 is provided at the tip of the push-up cylinder 23, and when the push-up cylinder 23 operates, the push-up tool 24
The sliding rod 18 is pushed up via the push-up plate 21.
is a structure that is pushed upward. Furthermore, an auxiliary cylinder 25 fixed to the main body is installed below the auxiliary plate 22. An auxiliary push-up tool 26 is also attached to the tip of the cylinder 25a of this auxiliary cylinder 25.
5 is activated, the auxiliary lifting tool 26 pushes up the plate 21 via the auxiliary plate 22,
The sliding rod 18 has a structure that can be pushed upward.
Here, the sliding rod 18 is pushed up by the action of the auxiliary cylinder 25 until the tip of the charging pin C fixed to the board B positioned on the base plate 19 comes into contact with the lower surface of the sliding plate 14. Set the location.

Further, the sliding rod 18 is pushed up by the action of the pushing up cylinder 23 when the slide plate 14 is moved from the position shown in FIG. 2 by the method described later.
The charging pin C provided in the positioning pin C faces the inside of the vertical guide hole 6 provided in the positioning transfer rod 5, pushes the upper end of the part A up to the holding plate 13, and then pushes it up to a position where it is press-fitted into the insertion hole of the part A. Set it like this. Further, the slide plate 14 has a structure that slides left and right in FIG. In this figure, a slider 28 is attached to a cylinder shaft 27a of a slide cylinder 27 fixed to the main body. The slide plate 14 is fixed to the lower part of the slider 28. Then, due to the action of the slide cylinder 27, the slide plate 14 reciprocates on the lower surface of the positioning transport rod 5 via the cylinder 28 attached to the tip of the cylinder shaft 27a, and when it is at the left position in the figure, it moves up and down. It acts as a cover for the lower surface of the guide hole 6. Moreover, when the board pushing up part 16 operates and the loading pin C faces the upper and lower guide holes 6,
It is set at the right position so as not to interfere with its operation.

The present invention has the structure described above, and first, the press-fitted parts A are conveyed one by one through the transport pipe 1 to the charging guide 2 by an alignment and separation device (not shown). Furthermore, the part A passes through the charging path 3 and waits at the bottom through the upper and lower guide holes 6 provided in the positioning transport rod 5.
is charged into the When the charging of the component A into the upper and lower guide holes 6 is confirmed by a confirmation device (not shown), the conveyance cylinder 7 starts operating. This conveyance cylinder 7
Since the cylinder shaft 7a is connected to the positioning conveyance rod 5 via the slider 8, the positioning conveyance rod 5 is pushed out along the conveyance groove 4 to the component press-fitting part 11, contacts the stop plate 15, and is positioned and stopped. . At this time, the part A in the vertical guide hole 6 is located at a position directly below the presser plate 13 at the upper side and on the slide plate 14 at the lower side. Then, the index table 17 is rotated by the operation of an indexing device (not shown), and the board B, which is positioned by the positioning pins 20 provided on the base plate 19, is placed in the component press-fitting section 1.
Position and stop below 1. At this time, board B
The charging pin C fixed to is positioned vertically below the part A. Following this positioning and stopping of the index table 17, the auxiliary cylinder 2
5 starts operating, and the auxiliary push-up tool 26 provided at the tip of the cylinder shaft 25a pushes up the auxiliary plate 22. For this reason, the push-up plate 21,
The substrate B on the base plate 19 is also pushed up via the sliding rod 18. Then, the operation of the auxiliary cylinder 25 is stopped when the charging pin C fixed to the substrate B is positioned immediately below the slide plate 14. Continuing from this state, the slide cylinder 27 begins to operate. The slider 28 moves to the second position by pushing the cylinder shaft 27a of the slide cylinder 27.
Move to the right side of the diagram. As a result, the slide plate 14 to which the slider 28 is attached is separated from the lower surface of the positioning conveyor bar 5. Therefore, the part A in the upper and lower guide holes 6 falls downward, but since the charging pin C is located directly below the upper and lower guide holes 6 by the action of the auxiliary cylinder 25, the part A moves its upper part into the upper and lower guide holes. 6, and the lower part is the positioning transport rod 5.
The lower end of part A is supported by the charging pin C in a state where it protrudes outside of the part A. From this state, the push-up cylinder 23 starts operating, and the push-up tool 24 pushes up the push-up plate 21 and the sliding rod 18 by pushing the cylinder shaft 23a of the push-up cylinder 23. Therefore, the loading pin C fixed to the substrate B positioned on the base plate 19 pushes up the component A supported at its upper end using the vertical guide hole 6 as a guide until the upper end of the component A comes into contact with the holding plate 13. Subsequently, the push-up cylinder 23 pushes the push-up plate 21, so that the insertion pin C is press-fitted into the insertion hole of the component A. Therefore, the component A is press-fitted into the insertion pin C of the board B from the upper and lower guide holes 6 and installed, and then the action of the push-up cylinder 23 and the auxiliary cylinder 25 is released, so that the component A is pushed downward together with the board B on the base plate 19. Thereafter, the index table 17 is rotated by an indexing device (not shown) to be transferred to the next working position.

In the present invention, the press-fitting part A is press-fitted into the insertion pin C fixed to the board B by the above-described operation.

As described above, according to the present invention, it is possible to obtain a device that allows a plurality of components to be automatically press-fitted into insertion pins fixed to a substrate in one operation.
As a result, workers were freed from the manual labor that had traditionally been performed. Furthermore, this device can be applied to and assembled into automatic assembly machines, special-purpose machines, etc., and can be used as an accessory device for various machines, contributing to labor savings.
