[0003] There is a certain tolerance between the existing carrier and the PCB board. The spacing between the sub-boards cannot be unified during the panelization process, which causes the printing and patch coordinates to shift and defective products to be produced during the production process. Therefore, a PCB board positioning carrier with a limiting structure is proposed to solve the above problem. Utility Model Content

DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figure 1-3 In this embodiment, a PCB board positioning carrier with a limiting structure includes a processing table 1, a limiting device 2 is arranged inside the processing table 1, a carrier body 3 is arranged inside the processing table 1, and a positioning structure 4 is arranged outside the carrier body 3.
[0023] The limiting device 2 includes a fixed rod 201, a spring 202, a movable block 203, a hinged rod 204 and a limiting plate 205. The fixed rod 201 is fixedly installed inside the processing table 1, the spring 202 is sleeved on the outside of the fixed rod 201, the movable block 203 is movably installed outside the fixed rod 201, the movable block 203 is hinged on the outside of the hinged rod 204, and the limiting plate 205 is hinged on the outside of the hinged rod 204.
[0024] The positioning structure 4 includes a slide groove 401, a card slot 402, a positioning pin 403, a sub-plate 404 and a portable slot 405. The slide groove 401 is opened on the top of the carrier body 3, the card slot 402 is opened on the top of the carrier body 3, the positioning pin 403 is movably installed inside the card slot 402, the sub-plate 404 is movably installed on the top of the carrier body 3, and the portable slot 405 is opened on the outside of the carrier body 3.
[0025] exist Figure 1 In the figure, the bottom of the carrier body 3 is in contact with the inner bottom wall of the processing table 1, and a portable slot 405 is provided on the outside of the carrier body 3, so that the operator can conveniently take the carrier body 3.
[0026] exist Figure 3 In the embodiment, there are two slide grooves 401 , which are respectively located at the front and rear sides of the top of the carrier body 3 , and the card slots 402 connected to the outside of the two slide grooves 401 are distributed in a relative state.
[0027] exist Figure 3 In the embodiment, the sub-board 404 is fitted with the carrier body 3 , the positioning pin 403 passes through the sub-board 404 and is movably connected with the sub-board 404 , and the distance between each of the slots 402 is uniform.
[0028] To summarize, the PCB board positioning carrier with a limiting structure moves the positioning pin 403 in the slide groove 401, and can limit the position of the positioning pin 403 through different card slots 402. When the positioning pin 403 passes through the sub-board 404 and limits the sub-board 404, it only needs to move the positioning pin 403 to the appropriate card slot 402 to ensure that the spacing between each sub-board 404 is uniform.

The position of the limiting plate 205 is adjusted according to the size of different carrier bodies 3. When the limiting plate 205 moves, it drives the hinge rod 204 to move and causes the movable block 203 to squeeze the spring 202, so that the limiting plate 205 and the carrier body 3 are more tightly fitted through the opposition of the spring 202, which facilitates the replacement and fixation of the carrier body 3, solves the problem that there is a certain tolerance between the existing carrier and the PCB board, and the spacing between the sub-boards 404 cannot be unified during the platemaking process, thereby causing the printing and patch coordinates to shift, and producing defective products during the production process.
