Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] Refer to Figures 1-4, A positioning tool for PCB board etching, including a bottom plate 1, characterized in that: a positioning mechanism is installed on the bottom plate 1. By setting the positioning mechanism, it serves the purpose of conveniently clamping and positioning PCB boards of different shapes, facilitating the etching process of PCB boards of different shapes. At the same time, the clamping plate 25 for clamping and positioning is convenient for disassembly and replacement. The positioning mechanism includes a groove 26, which is opened on the bottom plate 1. The shape of the groove 26 is a square groove. By setting the groove 26, it is convenient to limit the sliding of the slider 23. A rotating rod 24 is rotatably connected to the inner wall of the groove 26, and the rotating rod 24 is provided with a left-right thread. By setting the rotating rod 24 with a left-right thread, it is convenient to drive the two sliders 23 to slide towards or away from each other along the inner wall of the groove 26.

[0021] Specifically, a bracket 21 is fixedly installed on the side of the bottom plate 1. The shape of the bracket 21 is arched. The setting of the bracket 21 facilitates the installation of the first motor 22. A first motor 22 is fixedly installed on the inner wall of the bracket 21. The rotating shaft end of the first motor 22 is fixedly connected to one end of the rotating rod 24. The first motor 22 has a forward and reverse rotation function. The first motor 22 drives the rotating rod 24 to rotate, thereby achieving the purpose of driving the slider 23 to slide. The rotating rod 24 is threadedly connected with two sliders 23. The shape of the two sliders 23 is a square block. The sliders 23 slide on the inner wall of the groove 26. The setting of the sliders 23 facilitates the installation of the mounting plate 27.

[0022] Furthermore, a mounting plate 27 is fixedly installed at the top of the slider 23. The number of mounting plates 27 is two. The setting of the mounting plate 27 facilitates the installation of the shaft rod 29. A shaft rod 29 is rotatably connected to the mounting plate 27. A first gear 213 is fixedly installed at the top of the shaft rod 29. A second motor 28 is fixedly installed on the mounting plate 27. The second motor 28 has a forward and reverse rotation function. The rotating shaft end of the second motor 28 is fixedly installed with a second gear 212. The second gear 212 meshes with the first gear 213. When it is necessary to adjust the angle of the clamping plate 25, start the second motor 28. The second motor 28 drives the second gear 212 to rotate. The second gear 212 meshes with the first gear 213, and will drive the shaft rod 29 to rotate through the first gear 213. When the shaft rod 29 rotates, it will drive the clamping plate 25 to rotate through the connecting rod 214, the mounting box 215 and the mounting block 216 until the clamping plate 25 rotates to a suitable angle, facilitating the clamping and positioning of PCB boards of different shapes by the clamping plate 25.

[0023] Generally speaking, a connecting rod 214 is fixedly installed on the shaft rod 29. One end of the connecting rod 214 is fixedly installed with a mounting box 215. The mounting box 215 is in the shape of a square box, and the top end of the mounting box 215 is open. By providing the mounting box 215, it is convenient to receive the insertion of the mounting block 216. A spring 211 is fixedly installed on the side of the mounting box 215. One end of the spring 211 is fixedly installed with a bolt 210. The bolt 210 is used to be inserted into the slot 217. One end of the bolt 210 penetrates through the inner wall of the mounting box 215. The inner wall of the mounting box 215 is inserted with a mounting block 216. The mounting block 216 is in the shape of a square block. By providing the mounting block 216, it is convenient to receive the installation of the clamping plate 25. A slot 217 is opened on the side of the mounting block 216. The slot 217 is in the shape of a cylindrical groove. The top end of the mounting block 216 is fixedly installed with a clamping plate 25. The clamping plate 25 is in the shape of an L. When it is necessary to disassemble the clamping plate 25, pull the bolt 210 to pull one end of the bolt 210 away from the slot 217, and the mounting block 216 can be taken out of the mounting box 215, so as to achieve the purpose of disassembling the clamping plate 25.

[0024] Working mode; during work, place the PCB circuit board on the bottom plate 1, and then adjust the angle of the clamping plate 25 according to the shape of the PCB circuit board. The specific operation is as follows: first start the second motor 28, the second motor 28 drives the second gear 212 to rotate, the second gear 212 meshes with the first gear 213, and the shaft rod 29 will be driven to rotate through the first gear 213. When the shaft rod 29 rotates, it will drive the clamping plate 25 to rotate through the connecting rod 214, the mounting box 215 and the mounting block 216 until the clamping plate 25 rotates to an appropriate angle. Then start the first motor 22, the first motor 22 drives the rotating rod 24 to rotate. The rotating rod 24 is provided with a left-right thread, which will drive the two sliders 23 to slide towards each other along the inner wall of the groove 26. When the sliders 23 slide, they will drive the two clamping plates 25 to slide towards each other until the PCB circuit board is clamped and fixed, which is convenient for the PCB circuit board to be etched.

[0025] When it is necessary to disassemble the clamping plate 25, pull the bolt 210 to pull one end of the bolt 210 away from the slot 217, and the mounting block 216 can be taken out of the mounting box 215, so as to achieve the purpose of disassembling the clamping plate 25 and facilitate the replacement of the clamping plate 25.
