Description

Detailed Description of the Invention [Industrial Application Field] The present invention securely inserts an electronic component having two lead wires pulled out in the same direction while holding the lead wires at a predetermined distance using an insertion guide with one side open. The present invention relates to an electronic component insertion device that is inserted into a hole at a desired position on a wiring board.

[Conventional technology]

Conventional devices of this type include, for example, Japanese Patent Publication No. 57-53998.
As described in the above patent publication, a guide groove is formed in which the lead is formed and the tip is applied to a hole for inserting the lead wire provided in the printed wiring board (in the drawing of the embodiment described in the above patent publication). Press the tip of the lead wire against the guide body that has a rectangular groove (the cross-sectional shape of the groove is rectangular), and in this state slide the tip of the lead wire along the guide groove toward the tip side of the guide body to lead the lead wire of the electronic component. There was one that was designed to be inserted into a wire insertion hole. However, with the above device, it is difficult to grip the part in such a way that the tip of the lead wire always fits firmly into the guide groove of the guide body, such as when the lead wire cannot be formed or the part has a shape that is difficult to grip with a chuck. There was a problem with dechiru.

Additionally, there was an automatic insertion machine that clamped the ends of two lead wires of an electronic component and inserted them into the insertion hole of the circuit board. There was a problem that Kanashi required a large amount of space.

Furthermore, a device was used that chucked the main body of the electronic component and used a guide with one side open to reduce the space required near the insertion hole on the wiring board, but it was difficult to ensure that the lead wire tip entered the guide groove. There was a problem in that the insertion was not properly guided and insertion failures were likely to occur.

[Problem that the invention seeks to solve]

The present invention eliminates the problems of the conventional electronic component insertion device as described above, and provides an electronic component insertion device that is relatively simple, does not require a large space near the wiring board, and has a high lead wire insertion yield. The purpose is to provide

[Means for Solving the Problems] In order to solve the problems of the conventional device described above, in the present invention, the distance between the two lead wires drawn out in parallel from the electronic component body in the same direction. An insertion guide with one side open, which has two parallel V grooves carved on a flat surface at the same interval to guide the lead wire end to the hole into which it is inserted, and a position of the lead wire end with respect to this insertion guide. Two planes that almost match the position of the groove and include the lead wire and the V-groove are perpendicular to the plane of the guide in which the V-groove is carved, and within these two planes, the lead wire moves toward the V-groove. and a chuck that grips the electronic component body so as to be pressed diagonally at an acute angle. A mechanism is adopted in which the end of the lead wire is guided by the V-groove of the guide and moves to the position where it fits into the insertion hole on the wiring board.

[Effect]

The chuck that grips the electronic component body and the insertion guide operate simultaneously. At this time, the electronic component main body in the chuck is held in an inclined manner so that the tip of the wire is pushed into the insertion guide V@Vc located below one side of the chuck. The top width of the V-groove is wide (I think), and if the tip of the lead wire is located somewhere within this width, the tip of the lead wire will slide on the sloping side of the V-groove by being pressed, and the tip of the lead wire will slip on the sloped side of the V-groove. It reaches the bottom of ■ and is in a state where it is correctly guided by the groove. Therefore, when the chuck moves toward the wiring board, the tip of the lead wire pulled out from the electronic component body gripped by the chuck is guided into the V-groove of the insertion guide and inserted into the insertion hole drilled in the wiring board. reach and fit into the insertion hole. When the lead wire is inserted into the hole as desired, the opening/closing legs of the chuck open and stop gripping, and the head of the electronic component body (on the side opposite to the lead wire drawer), which is released from the chuck and becomes free, is Push down with the V-shaped concave surface of the pushing member installed near the crotch of the opening/closing leg, and push the electronic component body into the wiring board almost at right angles.

〔Example〕

FIG. 1(a) is a front view showing an embodiment of the present invention in which an electronic component to be inserted is gripped by a chuck and the lead wire tip has reached an insertion hole drilled in a main wiring board. Figure (b
) is a side view of the same state. A component chuck 7 and a head opening/closing lever 10 are attached via a pin 11 to a head housing 1 containing a chuck opening/closing piston 2 and a cylinder for vertically driving a pusher 5. The guide 6 is attached by a screw at the head opening/closing/<-10. Further, the head opening/closing lever 10 is assembled so as to transmit power through a spring 4, and this spring 4 is designed to absorb differences in dimensions of small parts.

As shown in FIG. 1(o), the device of the present invention (all locations indicated by K in FIG. 1(a)) picks up the electronic components 8 that are taped and aligned, and the chuck opening/closing piston 2 is operated by pneumatic pressure. The head opening/closing lever 10 is pushed through the opening/closing adjustment bolt 3, the head is opened/closed, the component chuck 7 is closed via the spring 4 attached to <-10, and the main body of the electronic component 8 is gripped. . , head opening/closing lever 10
A guide 6 is attached to the component chuck 7FC, and the guide 6 also operates at the same time as the component chuck 7 closes.
The tip of the lead wire of the electronic component 8 that has been placed is scooped in. The end surfaces of both legs of the component chuck 7 that grips the component 8 are provided with protrusions on the upper part of the left leg side and the lower part of the right leg side. Due to this protrusion, the electronic component 8 gripped by the component chuck 7 is held in a tilted state by the amount of the protrusion. The tilt of the part 8 forces the tip of the lead wire towards the bottom of the V-groove in the guide 6. This device, which has gripped the component 8, descends to a predetermined position on the wiring board 9, opens the component chuck 7, and then pushes down the component 8 with the insertion pusher 5, and inserts the lead wire of the component 8 into the insertion hole. let Since the end of the pusher 5 has a V-shaped concave surface, the head of the component 8 that was held at an angle (after the component chuck 7 is opened, the lead wire tip is inserted into the insertion hole, but this ’s head is free) is Butsusha 5’s V
It is inserted almost perpendicularly into the wiring board 9 following the concave shape.

[Effects of the Invention] As explained above, according to the present invention, by chucking the electronic component body diagonally, the tip of the lead wire of the component can be inserted into the guide V groove carved on the surface of the guide with one side open. Since the lead wire can be forcibly inserted all the way to the bottom, the tip of the lead wire is reliably guided to the insertion hole on the wiring board, making it possible to insert electronic components with a high yield. All you need is enough space for the release guide.
