[0022] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0023] The following disclosure provides many different embodiments or examples for implementing different solutions of the present invention.

[0024] Reference Figures 1 to 3 As shown, a TV motherboard separation jig includes a frame 1 and an operating unit 2. The operating unit 2 includes a base plate 21 and a cover plate 22. The cover plate 22 is hinged to the base plate 21 and is used to press the TV motherboard onto the base plate 21. The base plate 21 is provided with at least two grooves 211 for accommodating electronic components on the TV motherboard. A tool groove 212 is provided between two adjacent grooves 211. The cover plate 22 is provided with a notch for avoiding a milling cutter and electronic components on the TV motherboard. The cover plate 22 can press part of the edge of the TV motherboard, thereby pressing the TV motherboard.

[0025] The frame 1 is provided with a recessed portion for placing the bottom plate 21, and the frame 1 is provided with a bracket 3, on which a dust hood 4 is detachably mounted. The dust hood 4 is located above the recessed portion and is connected to an external negative pressure device.

[0026] The operating unit 2 is made into a detachable module, and the operating unit 2 is used to clamp the TV mainboard. When separating the boards, the operating unit 2 is taken out from the frame 1 and placed on the milling machine, and the board separation operation can be carried out. After the board separation is completed, the operating unit 2 is taken out from the milling machine and placed in the recessed part. After opening the cover 22, the dust on the bottom plate 21 and the TV mainboard can be absorbed by the dust hood 4. There is no need to manually use a brush to clean the dust, which greatly reduces the labor burden.

[0027] In this embodiment, a plurality of positioning blocks 213 are provided on the base plate 21, and the plurality of positioning blocks 213 cooperate to position the position of the TV mainboard on the base plate 21. After the TV mainboard is positioned, the electronic components on the TV mainboard will be located in the groove 211 to avoid damage to the electronic components. Then the cover plate 22 can be covered. During milling processing, the mechanism on the milling machine will press the cover plate 22 and the TV mainboard at the same time. The milling cutter moves along a preset path, and the gap allows the milling cutter to pass through. The tool groove 212 is for the milling cutter to extend into, to avoid the milling cutter damaging the base plate 21.

[0028] In this embodiment, the bracket 3 includes a top column 31 and a mounting plate 32. The top column 31 is fixed to the frame 1, and the mounting plate 32 is fixed to the top of the top column 31. The dust collection hood 4 includes a hood body 41 and a flexible pipe 42 connected to the hood body 41. The flexible pipe 42 is connected to the external negative pressure device. The mounting plate 32 is provided with a through hole, and the flexible pipe 42 passes through the through hole. The hood body 41 is located below the mounting plate 32, and the hood body 41 and the mounting plate 32 are detachably connected.

[0029] When in use, the cover body 41 is separated from the mounting plate 32, and the cover body 41 can be moved. The cover body 41 is lowered and covers the recessed portion to absorb dust. The flexible pipe 42 can be bent and deformed, so the flexible pipe 42 will not be torn when the cover body 41 moves.

[0030] Preferably, the dust cover 4 is detachably mounted on the bracket 3 by magnetic attraction, and the worker only needs to use slight force to tear off the cover body 41;

[0031] Specifically, a first magnetic block can be set on the cover body 41, and a second magnetic block can be set on the mounting plate 32. When the first magnetic block and the second magnetic block touch each other, the cover body 41 can be adsorbed on the mounting plate 32.

[0032] In this embodiment, a gas outlet is provided in the tool path 212, a first gas channel 214 is provided in the bottom plate 21, the gas outlet is connected to the first gas channel 214, and a second gas channel 11 is provided on the frame 1, and the second gas channel 11 is connected to an external gas supply device;

[0033] When the base plate 21 is placed in the recessed portion, the first gas channel 214 is connected to the second gas channel 11. When the dust hood 4 absorbs dust, the external air supply device will be started synchronously, allowing high-speed gas to enter the second gas channel 11, then pass through the first gas channel 214, and then be ejected from the air outlet, thereby blowing out the dust in the tool groove 212 to assist in cleaning the dust.

[0034] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
