The power supply is also common knowledge in the art. Therefore, this utility model will not explain the control method and circuit connection in detail.

[0026] In use, the meniscus lens 8 is placed on top of the rubber block 7 and the first rubber pad 6. Then, the controller 18 activates the electric telescopic rod 12 to move the moving block 11 and the clamping block 13 downwards. This causes the second rubber pad 15 in the arc groove 14 to press against the top of the meniscus lens 8, thus clamping and fixing the meniscus lens 8. At this time, the operator can then perform grinding operations on the right edge of the meniscus lens 8. When it is necessary to adjust the grinding position, the operator can activate the dual-axis servo motor 171 through the controller 18 to drive the two rotating shafts 173 and the two driving bevel gears 174 to rotate, which in turn drives the two worm gears through the two driven bevel gears 175. Rotating 161, and then driven by two worm gears 162, the two mounting shafts 3 and the meniscus lens 8 rotate as a whole, which facilitates the worker to grind different positions on the edge of the meniscus lens 8. After grinding, the electric telescopic rod 12 can be activated by the controller 18 to drive the moving block 11 and the clamping block 13 to move upward, thereby releasing the fixation of the meniscus lens 8. At this time, the meniscus lens 8 can be removed. When grinding the next meniscus lens 8, rotation is required. The dual-axis servo motor 171 can be activated to make it rotate in the opposite direction, so that the rotation direction of the meniscus lens 8 is opposite to the rotation direction of the previous meniscus lens 8, thereby ensuring the normal operation of the clamp.

[0027] In summary, this meniscus lens edge grinding clamp, by placing the meniscus lens 8 on top of the rubber block 7 and the first rubber pad 6, and then activating the electric telescopic rod 12 to drive the moving block 11 and clamping block 13 downwards, thereby squeezing the top of the meniscus lens 8 through the second rubber pad 15 in the arc groove 14, thus clamping and fixing the meniscus lens 8. At this time, the operator can then perform grinding operations on the right edge of the meniscus lens 8. When it is necessary to adjust the grinding position, the dual-axis servo motor 171 can be activated to drive the two rotating shafts 173 and the two driving bevel gears 174 to rotate, and then through the two driven bevel gears... Wheel 175 drives two worm gears 161 to rotate, and then two worm wheels 162 drive two mounting shafts 3 and the meniscus lens 8 to rotate as a whole. This makes it convenient for workers to grind different positions on the edge of the meniscus lens 8. The entire grinding process does not require manual handling of the meniscus lens, thereby improving safety and grinding efficiency. It is convenient for users and solves the problem that in the existing technology, when grinding the edge of a meniscus lens, it is usually necessary to manually hold the meniscus lens to grind the edge, which can easily cause injury to the worker's hands and result in low grinding efficiency, which is not conducive to operation.
