Abstract

PURPOSE:To cut a lead wire at uniform length by stable supporting a substrate through a process of engagingly locking/pushing the circumferential edge of the substrate by means of an engagingly locking member supported movably in plane direction on a frame body transported to the cutting tool side, and bringing the retaining tool for the frame body in contact with the surface of substrate. CONSTITUTION:A printed substrate 1 is engagingly locked and supported by locking parts 7a, 5a of a frame member and held by pushing force of a leaf spring 9. In addition, its circumferential edge is supported by a guide pin 15, while the surface of substrate 1 is maintained flat due to contact force of a retaining tool 17 restricting any bend liable to occur on the substrate 1. Both pin 15 and retaining tool 7 are vertically movable and also shiftable on a horizontal plane, accordingly any bend on the substrate can be almost perfectly prevented. Therefore, by moving the frame body toward cutting edge 3 side under this condition, a lead wire 2a can be cut out uniformly.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a conveying jig for conveying an electronic circuit package to a cutting tool side in order to cut the excess length of the lead wire of the package, and particularly relates to a conveying jig that conveys the package to a cutting tool side in order to cut the excess length of the lead wire of the electronic circuit package. The present invention relates to a transport jig for cutting lead wires of electronic circuit packages that can be applied to electronic circuit packages.

[Background of the invention]

As shown in FIG. 3, the electronic circuit package is formed from a printed circuit board 1 and various electronic components 2 mounted thereon. The lead wire 2α of the electronic component 2 is formed to be somewhat long, and the unnecessary lead wire is cut off by the cutting tool 3 after soldering.

There are various types of jigs for conveying the electronic circuit package to the cutting tool 3 side, but in the conventional technology, the one shown in FIG. There is a drawback that the series lead wire 2α is irregularly formed, and there is also a drawback that changes in the shape and dimensions of the printed circuit board 1 cannot be smoothly accommodated.

That is, as shown in FIG. 4, the printed circuit board 1 is supported horizontally by having its opposing peripheral edges clamped by pulleys 4 of the conveying means. By rotating the pulley 4, the shiblint board 1 is horizontally moved by the frictional force and is conveyed to the cutting tool 3 side, and the lead wire 2a is cut. In order to apply the above-mentioned frictional force, it is necessary to press the pulley 4 against the printed circuit board 1 side.For this purpose, as shown in FIG.
Warpage occurs. For this reason, the cutting length of the lead wire 2α varies, which deteriorates the product quality. On the other hand, when the width dimension of the printed circuit board 10 changes, the pulley 4 is moved from position A to position B as shown in FIG. Furthermore, as shown in FIG. 6, it is good if the peripheral edge of the printed circuit board 1 is held uniformly by the pulleys 4, but as shown in FIG. 7, depending on the shape of the printed circuit board 1, the pulley 4 may engage the peripheral edge unevenly. In some cases, the above-mentioned warpage is further exacerbated, and the printed circuit board 1 is not transported smoothly. In order to prevent this, the position of the pulley 4 must be changed each time, resulting in a disadvantage that setup time becomes longer and adjustment becomes impossible in some cases.

[Purpose of the invention]

The present invention solves the above-mentioned drawbacks, and its purpose is to cut lead wires of electronic circuit packages, which can ensure uniform lead length cutting regardless of the shape and dimensions of the printed circuit board, and reduce setup time. The purpose of this invention is to provide a transport jig.

[Summary of the invention]

In order to achieve the above object, the present invention provides a frame body that is supported by a conveying means such as the pulley and conveyed to the cutting tool side, and a locking member is supported on the frame so as to be movable in a plane direction, and the locking member is The member locks the peripheral edge of the printed circuit board to support it horizontally, and at least one of the locking members
and a biasing means for pressing the engaging part toward the printed circuit board, stably grips the printed circuit board, and supports a presser on the frame body so that its position can be adjusted in a horizontal direction, The present invention is characterized by a transport jig K for cutting lead wires of an electronic circuit package, which is formed so that one end thereof is in contact with the surface of the printed circuit board.

[Embodiments of the invention]

Embodiments of the present invention will be described below based on the drawings.

Without further ado, the outline of this embodiment will be explained with reference to FIG.

The locking member that horizontally supports the printed circuit board 1 is composed of a locking tool 5 and a guide bin 157, and the locking portion 5 (t,
15α engages with and supports the peripheral edge of the printed circuit board 10. The frame body is formed from a frame member 6.7, a guide shaft 20 installed between the frame members 6.7, a base 12 slidably supported by the guide shaft 12, and the like. The locking tool 5 and the kite bin 15 are supported by the frame body so as to be movable along the horizontal direction. The sweet frame body is pulley 4
is engaged with the blade, thereby being conveyed to the cutting tool side (not shown). The locking tool 5 is provided with a leaf spring 9 as a biasing means,
The locking portion 5a is pressed against the printed circuit board 1 side. A presser 17 is supported on the frame main body so that its position can be adjusted in the horizontal direction, and its tip is in contact with the surface of the printed circuit board 1.

The above configuration prevents the various types of printed circuit boards 1 from being warped while being transported to the cutting tool side.

Next, this embodiment will be explained in more detail.

Although warping tends to occur, the peripheral edge of the printed circuit board 1 is supported by the guide pins 15, and is suppressed by the contact force of the holding tool 17, so that the surface of the printed circuit board 1 is held flat. Both the kite pin 15 and the presser 17 are movable up and down as described above,
In addition, since it is movable on a horizontal plane, the above-mentioned warping can be almost completely prevented by adjusting it. By moving the frame body toward the cutting tool in this state, the lead wires are uniformly cut.

Next, when the width dimension of the printed circuit board 1 changes, this can be easily handled by adjusting the movement of the locking tool 5 along the guide shaft 20.

Even if the shape of the twisted printed circuit board 1 changes, the engagement between the pulley 4 and the frame body does not change, allowing smooth movement and adjusting the positions of the guide pin 15 and the holding tool 17 in the horizontal direction. The printed circuit board 1 is stably supported by
Moreover, the warpage described above is also prevented. Therefore, it is possible to quickly respond to printed circuit boards 1 of various shapes and sizes, and the setup time can be significantly reduced.

In this embodiment, the biasing means for the frame 8 is not limited to the leaf spring 9, but also the guide pin 15 and the presser 17.
The support mechanism and adjustment mechanism are not limited to those described above. Further, the number of guide pins 15 and presser tools 17 is not limited to two, and the biasing means does not have to engage only with the locking tool 5.
