[0036] The following will specifically describe the preferred embodiments of the present utility model with reference to the accompanying drawings. Among them, the accompanying drawings form a part of this application and are used together with the embodiments of the present utility model to explain the principle of the present utility model, and are not used to limit the scope of the present utility model.

[0037] An embodiment of the present utility model provides a circuit board splitting fixture, which is used to clamp and fix a circuit board 10a when splitting the circuit board 10a.

[0038] As shown in Figure 1 and 4As shown in FIG. -6, the circuit board splitting fixture of this embodiment includes a base 10, a cover plate 20, a sliding member 30, a pressing member 40, and an elastic member 50. The base 10 is provided with an installation groove 11 for installing the circuit board 10a to be split. The cover plate 20 is provided with a plurality of splitting grooves 21. The cover plate 20 is hinged to the base 10 and can press the circuit board 10a by rotating around the base 10. The sliding member 30 is vertically fixed to the base 10. The pressing member 40 is slidably connected to the sliding member 30 and can press and limit the cover plate 20 of the circuit board 10a by sliding along the sliding member 30. The elastic member 50 is sleeved on the sliding member 30 and abuts against the pressing member 40 for providing a pressing force towards the base 10 to the pressing member 40.

[0039] Specifically, the circuit board splitting fixture is provided with a base 10, a cover plate 20, a sliding member 30, a pressing member 40, and an elastic member 50. The base 10 is provided with an installation groove 11. The circuit board 10a to be split can be placed in the installation groove 11 for installation. The cover plate 20 is hinged to the base 10. The cover plate 20 fixes the circuit board 10a by pressing the circuit board 10a through rotation towards the base 10. The sliding member 30 is vertically fixed to the base 10. The pressing member 40 is slidably connected to the sliding member 30. The elastic member 50 is sleeved on the sliding member 30 and abuts against the pressing member 40. The pressing member 40 can press the cover plate 20 towards the base 10 under the elastic force of the elastic member 50. By pressing the cover plate 20, the cover plate 20 can be locked. The cover plate 20 is provided with a plurality of splitting grooves 21. After the cover plate 20 is locked, the splitting device can split the circuit board 10a through the splitting grooves 21, cut each connection node on the circuit board 10a, and finally split the circuit board 10a into several circuit board sub-boards to complete the splitting of the circuit board 10a. Since the locking force of the cover plate 20 is provided by the elastic force acting on the pressing member 40 by the elastic member 50, the locking force of the cover plate 20 can be adaptively adjusted by adjusting the elastic force of the elastic member 50 or according to the thickness of the circuit board 10a, thereby avoiding damage to the circuit board 10a while ensuring the stability of the circuit board 10a.

[0040] It can be understood that the base 10 can be any seat structure such as a plate body for placing the circuit board 10a.

[0041] In one of the embodiments, as Figure 1 and 4As shown in FIG. -6, the base 10 includes a support frame 12 and a support plate 13.

Specifically, the base 10 can be fixed on the board-splitting platform through the support frame 12 to provide support for the support plate 13. The support plate 13 can form an installation groove 11 structure for installing the circuit board 10a to be split. Since each board-splitting groove 21 on the cover plate 20 is located inside the support frame 12, after the splitting knife of the board-splitting device completes the splitting of the circuit board 10a, it can enter the inside of the support frame 12, thereby avoiding contact between the splitting knife and the board-splitting platform.

[0042] It can be understood that the cover plate 20 can be hinged to the base 10 through structures such as a rotating shaft.

[0043] In one embodiment, as Figure 1 、 3 and FIG. 5 show, the board-splitting fixture further includes a hinge 60. One side of the hinge 60 is fixed to the support plate 13, and the other side of the hinge 60 is provided with a mounting plate 61, and the mounting plate 61 is detachably fixed to the support plate 13. Specifically, the cover plate 20 can be hinged to the base 10 through the hinge 60, and the cover plate 20 can be detachably connected to the hinge 60 through the mounting plate 61, thereby improving the connection stability between the cover plate 20 and the hinge 60.

[0044] In one embodiment, as Figure 1 、 3 and FIG. 5 show, the mounting plate 61 is provided with a limiting groove 22, and the mounting plate 61 is detachably fixed to the limiting groove 22. Specifically, when assembling the board-splitting fixture, the mounting plate 61 can be first fixed to one side of the hinge 60, the hinge 60 is fixed to the support plate 13 through the other side, and then the cover plate 20 can be positioned and installed on the mounting plate 61 through the limiting groove 22, so as to realize the installation of the cover plate 20.

[0045] In one embodiment, as Figure 1-2 and FIGS. 4 - 6 show, the feeding slider 30 includes an adjusting screw 31, and the adjusting screw 31 is threadedly connected to the base 10. Specifically, by setting the feeding slider 30 as the adjusting screw 31, by screwing the adjusting screw 31, the elastic force of the elastic member 50 acting on the pressing member 40 can be adjusted, thereby realizing the adjustment of the pressing force on the cover plate 20 to adapt to the clamping of different types of circuit boards 10a.

[0046] It can be understood that one end of the elastic member 50 can be fixed to the adjusting screw 31, and the other end is movably arranged and abuts against the pressing member 40.

[0047] In one embodiment, as Figure 1-2As shown in FIGS. 5-6, the slider 30 further includes an abutting ring 32 sleeved on the adjusting screw 31, and both ends of the elastic member 50 abut against the abutting ring 32 and the pressing member 40 respectively.

Specifically, the limiting cavity 41 can provide protection for the elastic member 50 and ensure the stability of the elastic member 50 pressing the pressing member 40.

[0049] In one embodiment, as Figure 1-2 shown in FIGS. 4-6, the pressing member 40 is sleeved on the adjusting screw 31, and pressing portions 42 are provided on both sides of the pressing member 40 for pressing the cover plate 20 of the limiting circuit board 10a. Specifically, under the elastic action of the elastic member 50, the cover plate 20 can be pressed through the pressing portions 42 on both sides, thereby realizing stable locking of the cover plate 20.

[0050] In one embodiment, as Figure 1-2 shown in FIGS. 5-6, the cover plate 20 is provided with an unlocking groove 23, the pressing member 40 is located inside the unlocking groove 23, and the pressing portion 42 can enter the unlocking groove 23 through the rotation of the pressing member 40 to release the pressing on the cover plate 20. Specifically, through the above settings, when unlocking the cover plate 20, only need to rotate the pressing member 40 so that the pressing portion 42 of the pressing member 40 enters the unlocking groove 23 and disengages from the pressing on the cover plate 20, then the unlocking of the cover plate 20 can be realized, thus providing convenience for unlocking the cover plate 20.

[0051] It can be understood that the elastic member 50 can be any elastic structure such as rubber or sponge.
