[0029] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0030] Please refer to Figs. 1 to 3 The utility model provides a technical scheme:

[0031] A kind of etching positioning assembly suitable for PCB board, including positioning tool, it is characterized in that, the positioning tool including positioning plate 1 and lifting frame 2;The lifting frame 2 is installed in the top of positioning plate 1;The positioning plate 1 includes positioning frame 101, movable plate 102 and bottom plate 103, positioning frame 101 is convex, bottom plate 103 is installed in the bottom of positioning frame 101, movable plate 102 is movably installed in the top of positioning frame 101.

[0032] Specifically, two limit blocks 104 are arranged on the top of positioning frame 101, and an active slot 105 is formed between each limit block 104 and the frame of positioning frame 101. The slot 105 between the limit block 104 and the frame of positioning frame 101 can provide a precise active space for the limit block 104, ensuring that the limit block 104 can be finely adjusted according to the size of different PCB boards. This design not only improves the versatility of the assembly, but also ensures that the PCB board remains stable during etching, avoiding uneven etching or defects caused by movement or deviation.

[0033] Specifically, the movable plate 102 is T-shaped, which can provide better support force and stability during fixing. Since the horizontal expansion part of the T-shaped structure can cover a larger area, it helps to apply a more uniform fixing force, thereby avoiding the problem of loosening or deviation of the board during etching. At the same time, the horizontal expansion part of the T-shaped structure facilitates the installation of limiting devices or pressing locks 106 and other fixing components, further enhancing the restraining effect on the PCB board.

[0034] Specifically, two pressing locks 106 are arranged on the top of the movable plate 102, one on each side of the movable plate 102. The pressing locks 106 are arranged in the active slots 105 formed on the positioning frame 101, which can more stably fix the movable plate 102. The pressing locks 106 are embedded in the slots 105 formed on the positioning frame 101, which can firmly lock the position of the movable plate 102, keeping it stable within the positioning frame 101 and maintaining it within a predetermined track when the movable plate 102 moves. This ensures that the PCB board can be accurately positioned within the etching tool. The distribution position of the pressing locks 106 is optimized and evenly distributed on both sides of the movable plate 102. The movable plate 102 can ensure that the board remains horizontal during etching, preventing warping or deformation of the board.

[0035] Specifically, the movable plate 102 is provided with a handle block 107, which can be used to grab and move the movable plate 102 during use. The handle block 107 simplifies the operation process, making it more convenient to install and disassemble the movable plate 102, especially when replacing or adjusting the PCB board. The handle block 107 provides a convenient gripping point, reducing the difficulty of operation. The handle block 107 can also effectively avoid direct contact with the surface of the movable plate 102, thereby reducing the impact of static electricity or dirt on the etching precision of the PCB board, ensuring the cleanliness and precision of the processing process.

[0036] Specifically, the movable plate 102 is provided with a positioning block one 108, which can improve the positioning accuracy of the PCB board during etching. The positioning block one 108 provides a stable support and precise positioning point for the PCB board, ensuring that the PCB board is in the correct position during etching, avoiding displacement or misalignment. The design of the positioning block one 108 can adopt a modular structure, which is convenient for replacement and adjustment. The operator can quickly adjust the position of the positioning block one 108 or replace the positioning block of different specifications to adapt to the etching needs of various boards.

[0037] Specifically, the bottom plate 103 is U-shaped, which can fully expose the PCB board to the etching liquid, ensuring that the etching process is more uniform and comprehensive. This design is particularly suitable for PCB board processing that requires double-sided or multi-sided etching, effectively improving etching efficiency and reducing the risk of uneven etching. The U-shaped structure also helps to discharge bubbles and residues generated during etching, preventing them from adhering to the surface of the PCB board and affecting etching precision.

[0038] Specificly, the bottom plate 103 is provided with a plurality of positioning blocks two 109, which can provide precise support and restriction for the PCB board, ensuring that the PCB board always remains in the ideal position during etching, and will not be displaced or tilted due to liquid flow or vibration. The reasonable arrangement of the positioning blocks two 109 can ensure that the contact area between the PCB board and the bottom plate 103 is moderately distributed, so that the PCB board can be stable while fully contacting the etching liquid. The operator can quickly adjust the position of the positioning blocks two 109 or replace the positioning blocks of different specifications to adapt to the etching needs of various boards.
