Abstract

PURPOSE:To contrive the simplification of the clinch of leads and the simplification of the structure of a device itself by a method wherein a clinch component having inclined plane parts for bending lead legs is provided under a printed board. CONSTITUTION:An NL wire (a conductive wire) 8 is formed into a U-shaped form and both end parts 15 are formed into a V-shaped form in such a way that they are easy to insert in a printed board 17 and are guided by guide grooves 12. After an inserting device point 19 is inserted in a guide hole 10 in a guide plate 3, the NL wire 8 is pushed to the direction shown by an arrow A by a pressing device 6. Whereupon, the pushed NL wire 8 is made to descend along the grooves 12 and lead legs 16 are pushed in insertion holes 7 in the board 17. After that, by keeping pushing further the NL wire 8 to the direction shown by the arrow A by the device 6, both end parts 15 of the NL wire 8 are pushed against inclined plane parts 18 of a clinch component 9 provided under the lower part of the board 17 and the lead legs 16 are bent. By using the wire 8 subjected to forming in advance in such a way, the structure of an NL wire automatic inserting device is simplified and the insertion of the wire 8 and a clinch can be performed in one process.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device for inserting an NT-wire (conductive wire) into a printed board and fixing/supporting it on a printed board;
In particular, it relates to an NL line insertion method and insertion device.

[Conventional technology]

Conventionally, this type of NLM insertion device has an insertion head that holds the NLI& bent in a U-shape, an X-Y table that positions and holds the printed board, and a cutting and clinching (lead foot The method of insertion is to insert the NL wire bent into a U-shape into a component insertion hole provided at a predetermined position on the printed circuit board, and then insert Cutting the lead leg In the conventional configuration and method described above, a mechanism for cutting and clinching the lead leg after inserting the NL wire is required separately from the NL wire insertion device, making the overall configuration and structure of the device complicated. There was a problem with this. Another disadvantage was that it required two steps: pushing in the lead foot and cutting and clinching, which made the work more complicated.

Therefore, the present invention provides an insertion device that simplifies the structure of the device by using a preformed NL wire, and an insertion method that inserts and clinch the NL wire in one step.

[Means for Solving the Problem] The automatic NL wire insertion device according to the present invention has a lead foot that is inserted with the lead foot tip of the NL wire, which has been formed in advance into a shape that is easy to insert, facing the printed board. An insertion device that inserts the printed board into the insertion device while guiding it perpendicular to the printed board, a supply device that supplies the N L wire to the insertion device, and a device that inserts and supplies the printed board into the insertion device. a drive device that moves the nail in a direction perpendicular to the printed board; a clinch part that fixes the position of the printed board; and has a sloped part for clinching the lead leg protruding from the printed board at the same time as the NL wire is inserted; and the clinch part. The printed board is N. It is composed of a positioning device that positions the L wire according to the insertion position, and the lead foot tip of the NL wire, which has been formed in advance into a shape that is easy to insert, is directed toward the printed board, and the lead foot to be inserted is aligned with the printed board. The NL wire is guided perpendicular to the printed board, and the insertion device pushes the NL wire toward the printed board and inserts it into the insertion hole provided at a predetermined position on the printed board. At the same time, the lead leg protruding from the bottom of the printed board is printed. This NL wire insertion method is characterized by pressing against the sloped surface on the opposite side of the board to the insertion side (lower side of the printed board) and clinching immediately.This allows insertion and clinching to be performed in just one insertion step. It is something to do.

[Function] As explained above, the present invention is provided with a sloped surface inclined at a predetermined angle on the opposite side of the insertion device with respect to the printed board, and the insertion device is inserted into the insertion hole provided at a predetermined position of the printed board. Since the lead foot is bent by being pressed against the slope portion by the pressing force at the time of insertion of the NL wire, it is possible to clinch the lead foot.

[Practical example]

Practical examples of the present invention will be described below with reference to the drawings. FIG. 1 shows the basic structure of the automatic NL line insertion method of the present invention, and the automatic NL line insertion method of the present invention will be explained below. The NL wire 8 applied to the present invention has a U-shape, and both ends 15 have a V-shape so that it can be easily inserted into the printed board 17. This NL
The wire 8 is guided by a guide groove 12. After inserting the insertion device tip 19 into the guide hole 10 of the guide plate 3, the NL wire 8 is pushed as shown by arrow A by the pressing device 6. The pushed NL wire 8 descends along the guide groove 12,
The lead leg 16 is inserted into the insertion hole 7 of the printed board 17. After that, the suppression device 6 continues to push the NL wire 8 in the eight directions of the arrows, so that both ends 15 of the NL wire 8 are pushed onto the printed board 1.
The lead leg 16 is pressed against the slope part 18 of the clinch part 9 provided at the lower part of the lead leg 16, and is bent as shown in Fig. s2.

Next, an automatic insertion device using the above insertion method will be explained. FIG. 3 shows the automatic insertion device of the present invention, in which the insertion device 1 includes a U-shaped stable N L F
A supply device 2 is attached to store A8 and supply it one by one to the insertion device. The structure of the insertion device is shown in FIG. 6 is a pressing device for pushing out the NL wire 8, and the pressing device 6 is connected to the cylinder 1 via a link rod 13.
25, and is guided by the guide groove 12 and can slide up and down. Insertion device N shown in Figure 1
1 is attached to a drive device 19 so as to be movable in the downward direction. Reference numeral 20 denotes a base, on which is provided an X-Y table 21 that supports the printed board 17 and is movable in the X-Y directions. Inside the X-Y table 21 is a clinch head 22 having the slope 18 described above. The X-Y table 21 is equipped with a screw shaft 23 that moves the X-Y table 21 in the X-axis direction as shown by arrow X, and the screw shaft 23 is connected to the servo motor 2.
4 to move in the X-axis direction. Also, as shown by the arrow Y, it is equipped with a screw shaft 25 that allows the X-Y table 21 to be moved in the Y-axis direction.
The screw shaft 25 is rotated by a servo motor 26 to move in the Y-axis direction. Further, guide shafts 27 and 28 are provided to guide these operations. The combination of the X and Y axes allows movement in any direction.

FIG. 5 shows another practical example. This NL wire insertion device is designed so that the operator can insert it by hand.The insertion device 1 continuously stores U-shaped NL wires 8 and supplies them to the insertion device 1 one by one. A supply section 2 is attached. Further, a handle 29 is attached to the insertion device 1 so that the operator can hold the insertion device 1. As shown in FIG. 6, the printed board 17 is supported on a clinch plate 4 provided at a position corresponding to the insertion hole 7 of the printed board 7, and the clinch portion 9 of FIG. 30.

The clinch plate 4 is fixed to a base 31, and a hinge 11 is attached to the end of the clinch plate 4 to form a guide hole 10 for inserting and positioning the tip of the insertion device]9 at the insertion hole position of the printed board]7. Guide plates 3 provided at corresponding positions are attached to sandwich the printed board 17 so as to be openable and closable in the direction of arrow B, as shown in FIG.
