[0027] See appendix Figure 1 -Appendix Figure 5 As shown in the figure, an embodiment of the present invention provides a high-precision mask positioning fixture for pattern electroplating, including a processing table 1 for pattern electroplating and a positioning plate 101. The positioning plate 101 is disposed at one end of the processing table 1. A limiting plate 2 is fixedly installed at one end of the upper surface of the processing table 1. A slot is provided at one end of the processing table 1. A linkage block 202 slides into the slot. A positioning component 3 is fixedly installed at one end of the upper surface of the linkage block 202.

[0028] One end of the linkage block 202 is provided with a threaded hole, and a lead screw 103 is connected to the threaded hole. One end of the positioning plate 101 is provided with a motor 102, and the output shaft of the motor 102 is connected to one end of the lead screw 103. One end of the positioning plate 101 is fixedly installed with a guide rod 104, and the other end of the guide rod 104 passes through the linkage block 202 and is connected to one end of the inner wall of the slot of the processing table 1.

[0029] A second slot is provided on one side of the inner wall of the limiting plate 2, and a soft rubber block 203 is fixedly installed in the second slot. Both the clamping plate 201 and the limiting plate 2 are U-shaped.

[0030] In the above technical solution, the clamping plate 201 is driven to move by the lead screw 103. During the movement, the guide rod 104 ensures the stability of the movement. Then, the clamping plate 201 moves closer to the limiting plate 2 and clamps the substrate placed on the surface of the processing table 1. During the fixing process, the soft rubber block 203 installed on the inner wall of the clamping plate 201 can reduce the friction on the substrate. When the clamping plate 201 moves, it drives the positioning component 3 fixedly installed on the upper surface to move together, thereby ensuring high-precision positioning of the mask and the substrate and avoiding positional errors in the pattern electroplating mask process.

[0031] This embodiment of the utility model uses clamping plate 201 and limiting plate 2 to facilitate the placement of the substrate to be electroplated on the processing table 1, quickly completing clamping and positioning. Then, high-precision positioning is achieved through positioning component 3, avoiding the uncertainty of manual operation, meeting the requirements of mask positioning accuracy for pattern electroplating, and allowing for quick mask replacement, improving operational convenience, and preventing pattern burrs during subsequent electroplating, thereby improving the electroplating quality of the product.

[0032] See appendix Figure 4 , 5 As shown, the positioning component 3 includes a connecting plate 301. A mask frame 302 is fixedly installed on one side of the connecting plate 301. Fixing plates 303 are fixedly installed on both sides of the inner wall of the mask frame 302. A suction plate 307 is provided in the space between the fixing plate 303 and the mask frame 302. A connecting frame 304 is fixedly installed on the upper surface of both sets of connecting plates 301. An electric push rod 305 is provided at one end of the center of the upper surface of the connecting frame 304. The piston rod of the electric push rod 305 passes through the connecting frame 304 and is connected to a connecting rod 306. The other end of the connecting rod 306 is fixedly connected to one end of the upper surface of the suction plate 307. A vacuum pump 308 is provided at one end of the upper surface of the suction plate 307, and a through hole is provided at one end of the upper surface of the suction plate 307. A suction tube 309 is provided inside the through hole. The other end of the suction tube 309 is connected to the air extraction port of the vacuum pump 308. A vacuum suction cup 310 is connected to the lower surface of the suction tube 309. The suction tube 309 and the vacuum suction cup 310 are internally connected.

[0033] To improve the high precision of mask positioning, the connecting plate 301 moves along with the linkage block 202 driven by the lead screw 103, thus enabling precise positioning of the mask and substrate during substrate fixing. After positioning, the electric push rod 305 drives the suction plate 307 to descend, allowing the mask adsorbed by the vacuum suction cup 310 on the lower surface of the suction plate 307 to adhere to the substrate surface. Then, the vacuum pump 308 is turned off, and the vacuum suction cup 310 is pressurized, causing the mask to detach from the suction cup and remain on the substrate surface. Since the substrate is fixed to the limiting plate 2 by the clamping plate 201, and both the clamping plate 201 and the limiting plate 2 are U-shaped, displacement during electroplating that could cause pattern errors or short circuits can be avoided.

[0034] In this embodiment of the invention, the clamping plate 201 is driven to move by the lead screw 103. During the movement, the guide rod 104 ensures stability. Then, the clamping plate 201 moves closer to the limiting plate 2, clamping the substrate placed on the surface of the processing table 1. During the fixing process, the soft rubber block 203 installed on the inner wall of the clamping plate 201 can reduce friction on the substrate. Furthermore, when the clamping plate 201 moves, it drives the connecting plate 301 fixedly installed on the upper surface to move together, thereby facilitating the fixing of the substrate. It can accurately position the mask and substrate. After positioning, the electric push rod 305 drives the suction plate 307 to descend, so that the mask adsorbed by the vacuum suction cup 310 on the lower surface of the suction plate 307 is attached to the substrate surface. Then, the vacuum pump 308 is turned off, and the vacuum suction cup 310 is energized with atmospheric pressure. The mask is detached from the suction cup and remains on the substrate surface. Since the substrate is fixed to the limiting plate 2 by the clamping plate 201, and both the clamping plate 201 and the limiting plate 2 are U-shaped, it can avoid displacement during electroplating that could affect the pattern and cause short circuits.

[0035] In summary, the overall structure of this utility model embodiment has a high degree of accuracy in mask positioning, which can effectively align the mask with the substrate, reduce the impact of positioning errors on electroplating, and reduce the problem of mask displacement causing pattern burrs during electroplating.
