[0035] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0036] The panel separation jig and panel separation equipment of the present invention will be described below with reference to the accompanying drawings.

[0037] like Figure 1 and Figure 2 As shown, the utility model provides a panel splitting jig, wherein the panel splitting jig comprises:

[0038] The substrate body 100 is arranged on a fixture mounting seat of the panel separation equipment and is formed with a through space 101 enclosing the exhaust hole on the fixture mounting seat;

[0039] The carrier box 200 has a box cavity portion 250 and an outer plate portion 213. The outer plate portion 213 is overlapped on the side of the substrate body 100 away from the fixture mounting seat. The box cavity portion 250 is raised from the outer plate portion 213 toward the through space 101 to form a box cavity space 230 separated from the through space 101. The box cavity space 230 can be used for the components on the circuit board to be placed in position, and a cutting through hole 240 is opened on the side wall of the box cavity portion 250 to communicate with the through space 101 and separate from the box cavity space 230.

[0040] When using the above-mentioned board-splitting fixture, since it includes a substrate body 100 and a carrier box 200, the substrate body 100 can be arranged on the fixture mounting seat of the board-splitting fixture and is formed with a through space 101 that encloses the air extraction holes on the fixture mounting seat, so that the dust entering the through space 101 can be extracted. At the same time, the side plate part of the carrier box overlaps on the substrate body 100, and the box cavity part 250 bulges from the outer side plate part 213 towards the inside of the through space 101 to form a box cavity space 230 separated from the through space 101. And the cutting through hole 240 opened on the side wall of the box cavity part 250 is communicated with the through space 101 and separated from the box cavity space 230. Then, when the circuit board is split and cut through the cutting through hole 240, the generated dust directly flows towards the air extraction hole through the through space 101 and will not enter the box cavity space 230, so that the circuit board can be protected from being exposed to the dust space, reducing the influence of dust on the product cleanliness, without the need to additionally increase the dust cleaning action, and improving the production efficiency of the product.

[0041] Specifically, the cutting through hole 240 is selected to be opened on the side wall of the box cavity part 250 instead of the position corresponding to the outer side plate part 213 and the through space 101. On the one hand, it is to ensure the strength of the outer side plate part 213, and on the other hand, it is to direct the dust to a position closer to the air extraction hole instead of the overlapping gap between the outer side plate part 213 and the substrate body 100, ensuring sufficient dust suction and no leakage.

[0042] See Figures 2 to 4, in the embodiment of the present utility model, the carrier board box 200 includes a carrier tray 210 and an open box body 220. The open box body 220 forms a box cavity space 230. The carrier tray 210 is detachably arranged at the open end of the open box body 220 and is provided with a placement opening 211 communicating with the box cavity space 230. And the carrier tray 210 is sequentially provided with an inner surrounding plate portion 212 and an outer edge plate portion 213 from the inside to the outside of the placement opening 211. The inner surrounding plate portion 212 is attached to the open end of the open box body 220, and the cutting through hole 240 penetrates through the side wall of the open box body 220 and the inner surrounding plate portion 212. That is, the carrier box can be split into a carrier tray 210 and an open box body 220. On the one hand, it is convenient for production and processing. On the other hand, different materials can be selected for the carrier tray 210 and the open box body 220 according to specific functions to achieve the best use performance. At the same time, the carrier tray 210 and the open and close box body are detachably connected, so as to achieve the purpose of disassembly, repair and replacement. Specifically, the inner surrounding plate portion 212 of the carrier tray 210 can be detachably arranged on the open end of the open box body 220 through threaded fasteners. In addition, the inner surrounding plate portion 212 of the carrier tray 210 is attached to the open end of the open box body 220, so that the carrier tray 210 plays a role in carrying and supporting the circuit board. In order to ensure that the circuit board will not be damaged, the carrier tray 210 can be subjected to corresponding surface treatment to ensure appropriate roughness. Of course, the present utility model is not limited to this. It is also possible to integrally form the carrier box with the same material.

[0043] Specifically, the number of the open box bodies 220 can be at least two, and the number of the placement openings 211 on the carrier tray 210 can also be at least two. The at least two placement openings 211 are spaced apart on the carrier tray 210, and the at least two open box bodies 220 are respectively arranged in one-to-one correspondence with the at least two placement openings 211 for the at least two circuit board products on a spliced whole board to be placed in one-to-one correspondence.

[0044] Such as Figure 2 And Figure 3As shown, in the embodiment of the present utility model, the open box body 220 includes a bottom support plate 221 and a heightening frame 222. The heightening frame 222 is enclosed around to form the side wall of the box cavity space 230. The bottom support plate 221 is detachably arranged at one end of the heightening frame 222 and is used to form the bottom wall of the box cavity space 230. The end of the heightening frame 222 away from the bottom support plate 221 is used to form the open end of the open box body 220 and is detachably connected to the load-carrying support plate 210. And the heightening frame 222 is arranged to be detachably stacked in the height direction. That is, the open box body 220 can be divided into the bottom support plate 221 and the heightening frame 222. The bottom support plate 221 forms the bottom wall of the box cavity space 230, and the heightening frame 222 forms the side wall of the box cavity space 230. The number of the heightening frames 222 is not limited to one. When the height of the box cavity space 230 needs to be adjusted, it can be achieved by adjusting the number of the stacked heightening frames 222, so as to improve the versatility of the fixture. Further, between the bottom support plate 221 and the heightening frame 222, between the heightening frame 222 and the load-carrying support plate 210, and between two adjacent stacked heightening frames 222, they can all be detachably connected by threaded fasteners.

Then, the single circuit board product after the board splitting can completely fall on the inner peripheral plate portion 212 and be separated from the spliced whole board falling on the outer edge plate portion 213 in the height direction. At the same time, a first handle groove 214 that is flush with or lower than the inner peripheral plate portion 212 is formed on the side of the outer edge plate portion 213 away from the open box body 220. By adding the first handle groove 214, it is convenient to take the single circuit board product after the board splitting.

[0046] In the embodiment of the present utility model, the number of the cutting through holes 240 can be multiple. The multiple cutting through holes 240 are arranged at intervals in sequence along the circumferential direction of the placing opening 211. And a positioning rib 215 for positioning the circuit board is convexly arranged on the inner peripheral plate portion 212 between two adjacent cutting through holes 240. The positions of the multiple cutting through holes 240 can be set correspondingly according to specific requirements. By adding the positioning rib 215 between two adjacent cutting through holes 240, the circuit board can be positioned to ensure the stable board splitting of the circuit board.

[0047] In the embodiment of the present utility model, the load-carrying support plate 210 can be set as a metal part with hard anodizing treatment. The setting of the metal part is convenient for corresponding surface treatment. Hard anodizing treatment is carried out on the load-carrying support plate 210 made of the metal part, which not only ensures the roughness of the load-carrying support plate 210 but also enhances the load-carrying support plate 210.

[0048] In the embodiment of the present utility model, the open box body 220 can be made of bakelite. Making the open box body 220 with bakelite material can not only ensure light weight but also ensure high mechanical strength, facilitating the detachable splicing of the bottom support plate 221 and the heightening frame 222 which are separately arranged with threaded fasteners.

[0049] See Figure 1 , in the embodiment of the present utility model, the substrate body 100 is sequentially provided with a lapping plate portion 102 and a mounting plate portion 103 from the inside to the outside of the through space 101. The mounting plate portion 103 is detachably mounted on the fixture mounting seat. The lapping plate portion 102 is arranged lower than the mounting plate portion 103 on the side facing away from the fixture mounting seat, so that the outer edge plate portion 213 of the carrier board box 200 can be aligned and snap-fitted and lapped. The solid part of the substrate body 100 is divided into the lapping plate portion 102 and the mounting plate portion 103 from the inside to the outside, and the side of the lapping plate portion 102 facing away from the fixture mounting seat is arranged lower than the mounting plate portion 103, so that the outer edge plate portion 213 of the carrier board box 200 can be reliably lapped on the lapping plate portion 102.

[0050] Specifically, the substrate body 100 can be designed according to the dimensions of the positioning posts and threaded connection holes on the fixture mounting seat.

The sinking width of the lapping plate body on the substrate body 100 can be 15 mm, and the sinking depth can be 3 mm.

[0051] In the embodiment of the present utility model, magnets 104 are embedded in the lapping plate portion 102 and the outer edge plate portion 213 in a corresponding manner. Then the carrier board box 200 can be reliably placed on the lapping plate portion 102 through magnetic attraction and the carrier board box 200 can be changed in type. In addition, positioning pins 105 can be provided on the lapping plate portion 102, and positioning holes for the positioning pins 105 to pass through are opened on the outer edge plate portion 213 of the carrier board box 200. Specifically, magnets 104 and positioning pins 105 are provided at the four corner positions of the lapping plate portion 102, and magnets 104 are correspondingly embedded and positioning holes are opened on the back of the outer edge plate portion 213, so that when replacing different types of carrier board boxes 200, they can be attracted through magnetic attraction, reducing the operation of removing screws and achieving rapid type change.

[0052] In an embodiment of the present utility model, an anti-fooling structure 106 is provided at one of the corner positions of the overlapping plate portion 102, and the outer edge plate portion 213 of the carrier box 200 is shaped according to the anti-fooling structure 106.
