Description

Technical Field

[0001] This utility model relates to the field of plate-shaped product clamping technology, and more specifically, to a clamping device. Background Technology

[0002] In the field of semiconductor packaging materials, vertical wet-process manufacturing of PCBs (printed circuit boards), glass substrates, or carriers is crucial. However, current processing technologies have significant shortcomings in the use of fixtures. In vertical wet processing flows, especially in the critical DES (development, etching, and stripping) process, traditional fixtures remain in a clamped state at all times. This causes the solder mask (liquid photosensitive solder resist) at the clamping points to be blocked by the clamps, preventing it from fully participating in the process. This phenomenon leads to a series of problems: the solder mask at the clamping points cannot be fully exposed to the process due to the blockage, resulting in insufficient or low curing and reduced adhesion; in the washing stage, the liquid solvent cannot fully contact and remove the solder mask and other impurities at the clamping points because they are blocked by the fixtures, which may lead to stains, residues, and other problems, affecting circuit uniformity and even causing failure. Therefore, we have made improvements to address this issue and proposed a clamping device. Utility Model Content

This effectively solves the problem of incomplete green oil washing, allowing the green oil at the clamping points to fully participate in the process flow, improving the uniformity of the board and reducing unevenness or failure of the circuit due to clamping point problems. The automated transmission operation and intermittent clamping design reduce manual intervention, improve production efficiency, and simultaneously reduce labor and material costs.

[0043] The clamping device provided by this utility model is used as follows:

[0044] For ease of understanding, this application uses C to denote the plate-shaped product that needs to be clamped. First, the clamping module 300 is removed from between the bottom active drive module 100 and the top driven drive module 200 and placed horizontally. The lower shaft 312 is removed. Then, using the existing rods, the clamps 340 on both sides are pressed simultaneously to open all the clamps 340. The plate-shaped product is passed between the two straight racks 320 and aligned with the position of the clamps 340. The existing rods are released so that the clamps 340 clamp the plate-shaped product. Then, the lower shaft 312 and the support shaft are... After the rods 313 are connected together, the clamp module 300 is placed between the bottom active transmission module 100 and the top driven transmission module 200. The motor drives the main shaft 109 to rotate through the coupling 111. During the rotation of the main shaft 109, the transmission rod 101 is driven to rotate through the second bevel gear 103. During the rotation of the transmission rod 101, the spur gear 105 is driven to rotate through the first bevel gear 104 and the transmission shaft 106. The rotation of the spur gear 105 drives the rack 320 to move, thereby driving the clamp module 300 to move horizontally.

[0045] During the horizontal movement of the clamp module 300, the clamps 340 at odd and even positions open alternately. Specifically, when the front and rear pressure handles 341 reach the extrusion roller body 402, the extrusion roller body 402 extrudes the front and rear pressure handles 341, causing the fluororubber pressure block 345 to release the plate-shaped product. When the extrusion roller body 402 separates from the front and rear pressure handles 341, the attraction force of the magnet 342 and the force of the return spring 344 can drive the front and rear pressure handles 341 to return to their original positions, so that the fluororubber pressure block 345 clamps the plate-shaped product.
