[0002] In the production of PCB board, the conventional board separating process usually needs to use a board separating die, first, the PCB board to be cut is placed on the die, then the die is placed on a cutting machine, and finally the cutting machine cuts the PCB board to complete the board separating process.

[0003] At present, in order to facilitate the treatment of dust generated after the board is separated, a plurality of dust suction holes are formed in the board separating die, when dust removal starts, the dust suction holes are sealed by a circular brush, and finally the dust is sucked through the dust suction holes by a dust suction device. The peripheral wall of the dust suction hole is usually a vertical wall, which causes some dust to remain on the wall and cannot be sucked out, so that when the board separating die and the PCB board are separated, the dust falls on the PCB board, thereby polluting the PCB board and seriously affecting the quality of the PCB board. Moreover, the remaining dust is difficult to clean on the PCB board, and the cleaning time is long, the cleaning steps are complicated and complex. SUMMARY

The inclined direction of the inclined wall surface is from the upper opening to the lower opening and gradually approaches the center of the lower opening. A plurality of dust suction holes are provided on the main plate.

[0007] Preferably, the inclined wall surface is rectangular and comprises a front wall surface, a left wall surface, a rear wall surface and a right wall surface connected in sequence.

[0016] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0017] ​​It should be understood that the terms "length", "width", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like specify the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0018] In addition, the terms "first", "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0019] Figures 1-4is a schematic view of a board separating jig 100 according to embodiments of the present application. The board separating jig 100 is used in a board separating process for a PCB 200, and can improve the positioning and fixing of the PCB 200 during the board separating process. In detail, the board separating jig 100 is used to fix the PCB 200 to be separated, and is located below a dust suction device. The board separating jig 100 includes a main plate 1 and a dust suction hole 2 provided on the main plate 1. The dust suction hole 2 has an upper opening 201 and a lower opening 202 at the upper and lower ends thereof, respectively, and the upper opening 201 and the lower opening 202 are provided on the upper wall and the lower wall of the main plate 1, respectively. In use, the board separating jig 100 is pressed on the PCB 200, and the lower opening 202 abuts against the upper wall of the PCB 200. The area of the upper opening 201 is larger than that of the lower opening 202. An inclined wall 3 is formed on the wall surface of the main plate 1 between the upper opening 201 and the lower opening 202, and surrounds the center of the dust suction hole 2. The inclined wall 3 is inclined in a direction from the upper opening 201 to the lower opening 202, and gradually approaches the center of the lower opening 202. Compared with the conventional vertical wall, the inclined wall 3 has a larger wall surface area around the dust suction hole 2. When the PCB 200 is separated by a milling cutter 400, the brush 300 can cover a larger wall surface area during dust suction, so that the dust suction device can collect more dust, thereby effectively cleaning the dust around the dust suction hole 2, greatly reducing the residual dust, effectively solving the problem of residual dust around the dust suction hole 2 after the board separating process, and improving the efficiency of dust treatment. Further, a plurality of dust suction holes 2 are provided on the main plate 1, and the arrangement mode of the plurality of dust suction holes 2 can be various. The specific arrangement mode is selected according to the type of the PCB to be separated. In addition, a mounting hole 4 is provided on the main plate 1, and the mounting hole 4 is used for mounting a bolt. The main plate 1 is mounted on the PCB by the bolt passing through the mounting hole 4, that is, the mounting hole 4 is matched with the mounting of the bolt to realize the mounting and fixing of the main plate on the PCB.

[0020] As a preferred embodiment, refer to Figure 2 and Figure 3The inclined wall surface 3 is rectangular and comprises a front wall surface 301, a left wall surface 302, a rear wall surface 303 and a right wall surface 304 connected in sequence, and the inclined angles of the front wall surface 301, the rear wall surface 303, the left wall surface 302 and the right wall surface 304 are all 60 degrees. That is, the dust absorption hole 2 formed by the inclined wall surface 3 composed of the front wall surface 301, the left wall surface 302, the rear wall surface 303 and the right wall surface 304 is rectangular, and the inclined angles of each wall surface are all 60 degrees, so that the surface area of the inclined wall surface 3 is maximized without affecting the overall structure of the plate separating jig, so as to achieve better dust removal effect. Secondly, the upper opening 201 and the lower opening 202 of the inclined wall surface 3 are both rectangular. In addition, the inclined wall surface 3 can also be cylindrical, and the inclined angle is also 60 degrees, and can also be other shapes.
