Detailed ways

In order to facilitate the understanding of those skilled in the art, the utility model will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the implementation modes are not limitations of the utility model. Below in conjunction with accompanying drawing, the utility model is described in detail.

An adjustable board splitting jig provided by the utility model includes a jig base 1 and at least one knife plate 2 for cutting circuit boards, as shown in Figure 1, above the jig base 1 4 cutter boards 2 are installed, so when in use, a large circuit board is cut into 5 small circuit boards at one time, which can effectively improve the speed of board separation; the fixture base 1 is provided with There are two T-shaped connecting grooves 3 , and a locking connecting piece 4 is arranged between the knife plate 2 and the T-shaped connecting groove 3 , and the knife plate 2 is slidably installed above the T-shaped connecting groove 3 through the locking connecting piece 4 . In the present utility model, a knife groove 5 and a blade (not shown in the figure) are arranged in the middle of the knife plate 2 , and the blade is vertically inserted into the knife groove 5 . The blade 5 is fixed on the knife plate 2. Before cutting, the cutting position of the knife plate 2 is adjusted by sliding, the circuit board is positioned on the top of the knife plate 2, and then punched to separate the boards.

Further, a steel baffle is provided below the sipe 5, and the bottom of the blade abuts against the steel baffle. When cutting the circuit board, the blade will be subjected to a large downward pressure. If the lower part of the blade is in direct contact with the jig base 1, the blade may sink. Since the steel baffle has strong hardness, the blade Will not be pressed into the steel baffle, which means no sagging.

Further, the blade 2 is provided with at least two retractable positioning rods for limiting the position of the circuit board, the retractable positioning rods include a return spring and a positioning rod 6, and a positioning Through hole, the positioning rod 6 passes through the return spring and is movably installed in the positioning through hole. Before the circuit board is cut, a through hole for cutting and positioning has been punched out on the circuit board, and the through hole of the circuit board is inserted in the positioning rod 6, so that the circuit board can be placed on the knife plate 2 easily. The positioning rod 6 has a certain height, and multi-layer circuit boards can be stacked and placed on the knife plate 2 at the same time, so as to realize one-time cutting of multi-layer circuit board products, and effectively improve the speed and quality of board splitting. Since the position of the knife plate 2 is fixed, and the circuit board is positioned by the positioning rod 6, there will be no deviation during cutting, thus overcoming the problem of cutting deviation.

Still further, the lower end of the positioning rod 6 passes through the positioning through hole, and the jig base 1 is provided with an avoidance groove 7 corresponding to the positioning rod 6, so as to ensure that the positioning rod 6 has enough space to expand and contract downwards. . When cutting the circuit board, the positioning rod 6 can be compressed downwards, so that the pressing die combined with the sub-board jig is in parallel contact with the upper surface of the circuit board, so that all circuit boards can be cut at one time.

In the present utility model, the locking connector 4 includes a T-shaped connecting block 8 and a countersunk screw 9, the T-shaped connecting block 8 is located in the T-shaped connecting groove 3, and the knife plate 2 corresponds to the T-shaped A stepped hole 10 is provided at the connecting groove 3 , and the countersunk screw 9 passes through the stepped hole 10 to connect with the T-shaped connecting block 8 . When it is necessary to adjust the position of the knife plate 2, use a screwdriver to adjust the tightness between the countersunk screw 9 and the T-shaped connecting block 8, and apply force to make the knife plate 2 move along the T-shaped connecting groove 3, which can be quickly adjusted Comply with the requirement of sub-board spacing. When designing circuit boards, the spacing of small boards can be reduced to improve the utilization rate of materials.
