[0023] The usage method of the above-mentioned contact lens male mold polishing equipment specifically includes the following steps: S1. Start the vibrating bowl 2. During the process of the male mold moving to the output end of the vibrating bowl 2, the moving drive guide member 301 drives the telescopic cylinder 4 303 to move the pneumatic finger member 1 304 to the output end of the vibrating bowl 2. The telescopic cylinder 4 303 extends. When the male mold moves to the output end of the vibrating bowl 2, turn off the vibrating bowl 2. The pneumatic finger member 1 304 closes to clamp the male mold. The moving drive guide member 301 drives the pneumatic finger member 1 304 to drive the male mold to move to directly above the positioning copper head 1 305 through the telescopic cylinder 4 303. The telescopic cylinder 4 303 contracts to sleave the male mold on the positioning copper head 1 305. The pneumatic finger member 1 304 opens. Repeat the operation to sleave several male molds on several positioning copper heads 1 305 respectively to complete the pre-arrangement of the male molds. S2. Control the telescopic cylinder 1 405 to extend. The telescopic cylinder 1 405 drives the assembly plate 406 to move several pneumatic finger members 2 407 to directly above the pre-arranged male molds. The pneumatic finger members 2 407 close to clamp the male molds. Then control the telescopic cylinder 1 405 to contract. The moving drive guide member 2 401 drives the transplanting plate 403 to move the vertical assembly frame 404 forward. The vertical assembly frame 404 drives the assembly plate 406 through the telescopic cylinder 1 405 to move several pneumatic finger members 2 407 clamping the male molds to directly above the positioning copper head 2 504. Control the telescopic cylinder 1 405 to extend to sleave the male molds on the positioning copper head 2 504. The pneumatic finger members 2 407 open. Control the telescopic cylinder 1 405 to contract. S3. Control the second telescopic cylinder 501 to contract. The second telescopic cylinder 501 drives the positioning frame 502 to move to the polishing position. Control the third telescopic cylinder 609 to contract, so that the pallet 6010 disengages from the extension rod 605. Affected by gravity, the counterweight 607 drives the fixed block 604 through the extension rod 605 to rotate the rotating shaft 603. During this process, the extension rod 605 drives the positioning rod 606 to make the polishing head 608 sleeved on the male mold. Start the polishing motor 503. The polishing motor 503 drives the second positioning copper head 504 to rotate, and cooperate with the polishing head 608 to polish the male mold. During this process, start the swing motor 6011. The swing motor 6011 drives the rotating block 6012 to rotate. The rotating block 6012 drives a vertical plate 602 to move left and right reciprocally through the connecting rod 6013, so that the rotating shaft 603 drives the extension rod 605 through the fixed block 604 to make the positioning rod 606 move left and right reciprocally. The positioning rod 606 drives the polishing head 608 to move left and right reciprocally; S4. After the polishing of the male mold is completed, control the third telescopic cylinder 609 and the second telescopic cylinder to reset in sequence. Transfer the polished male mold to the receiving tray 102 through the male mold transfer assembly 4. Specifically, use the second pneumatic finger assembly 407 to clamp the polished male mold and transfer it to the receiving tray 102. Then when the second pneumatic finger assembly 407 moves to directly above the first positioning copper head 305, the reset of the male mold transfer assembly 4 is completed.
