[0042] In this embodiment, linear sliders are fixedly connected to both ends of the bottom of the displacement frame 3, and the two linear sliders are slidably connected to the two linear guide rails 2 respectively. By setting the linear sliders, the displacement frame 3 can move stably on the linear guide rails 2. The cross-sectional shape of the linear guide rails 2 is I-shaped.

[0043] In this embodiment, the trimming component 7 includes:

[0044] The displacement plate 9 is vertically slidably connected to the inner side of the support frame 4. The top of the support frame 4 is fixedly connected to an electric push rod 10, and the output end of the electric push rod 10 is fixedly connected to the displacement plate 9.

[0045] Linkage shaft 11 is vertically rotatably connected to one end of displacement plate 9. Fine grinding disc 12 and coarse grinding disc 13 are fixedly connected to the bottom and top ends of the outer side of linkage shaft 11, respectively.

[0046] The transmission shaft 14 is vertically rotatably connected to the inner side of the support frame 4, and the linkage shaft 11 is also slidably connected to the outer side of the transmission shaft 14. The top of the support frame 4 is fixedly connected to the transmission motor 15, and the output end of the transmission motor 15 is fixedly connected to the transmission shaft 14.

[0047] In this embodiment, a linkage bar is fixedly connected to the outer side of the transmission shaft 14, and a linkage groove is provided on the inner wall of the linkage shaft 11. The linkage bar is also slidably connected inside the linkage groove. Through the setting of the linkage bar and the linkage groove, the linkage shaft 11 can slide stably along the vertical direction of the transmission shaft 14, and when the transmission shaft 14 rotates, the linkage bar can drive the transmission shaft 14 to rotate synchronously.

[0048] Example 2:

[0049] Please see Figure 1-5 This embodiment provides a technical solution based on Embodiment 1: In this embodiment, the lens support assembly 8 includes:

[0050] The mounting frame 16 is fixedly connected to the end of the bearing seat 1 away from the linear guide rail 2. The top of the mounting frame 16 is vertically rotatably connected to a hollow shaft 17, and the top of the hollow shaft 17 is fixedly connected to a positioning plate 18.

[0051] The transmission tube 19 is vertically fixedly connected to the middle of the hollow shaft 17, and the top end of the transmission tube 19 is connected to the inner cavity of the positioning plate 18. A vacuum pump 20 is fixedly connected to one side of the mounting frame 16. An outlet tube 21 is fixedly connected to the input end of the vacuum pump 20, and the end of the outlet tube 21 away from the vacuum pump 20 is rotatably connected to the bottom end of the transmission tube 19.

[0052] The drive motor 22 is fixedly connected to the top of the mounting frame 16. The output end of the drive motor 22 is fixedly connected to the transmission spur gear 23. The outer side of the hollow shaft 17 is fixedly connected to the reduction spur gear 24, and the transmission spur gear 23 and the reduction spur gear 24 are meshed together.

[0053] In this embodiment, the top of the positioning disk 18 is provided with multiple suction holes, and each suction hole is fixedly connected to a suction cup. By setting the suction holes, when the round eyeglass lens is placed above the lens support assembly 8, the round eyeglass lens can block the suction cup. When a negative pressure is generated inside the positioning disk 18, the round eyeglass lens can be stably adsorbed by the suction cup.

[0054] In this embodiment, a retainer is fixedly connected to the bottom end of the mounting frame 16, and the outlet tube 21 is also fixedly connected to one end of the retainer. By setting the retainer, the outlet tube 21 can be auxiliaryly supported to prevent the outlet tube 21 from shaking when transmitting gas.

[0055] In this embodiment, a rotary joint is provided at the connection between the outlet pipe 21 and the transmission pipe 19, and the outlet pipe 21 and the transmission pipe 19 are connected by the rotary joint. By providing the rotary joint, the gas can be effectively transmitted without affecting the rotation of the transmission pipe 19.

[0056] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0057] Working principle: First, place the round eyeglass lens on the top of the positioning plate 18 and start the vacuum pump 20 to extract the gas inside the positioning plate 18 through the outlet pipe 21 and the transmission pipe 19, so as to create a negative pressure environment inside the positioning plate 18 until the round eyeglass lens is adsorbed on the positioning plate 18, thereby achieving the positioning of the round eyeglass lens.

[0058] The hydraulic cylinder 6 is activated to push the support frame 4 closer to the circular lens under the limit of the linear guide rail 2 until the coarse grinding disc 13 contacts the circular lens. Then, the transmission motor 15 is activated to drive the transmission shaft 14 to rotate. With the connection between the transmission shaft 14 and the linkage shaft 11, the linkage shaft 11 can drive the coarse grinding disc 13 to rotate. By using the contact between the coarse grinding disc 13 and the edge of the circular lens, the edge is ground and trimmed. At the same time, the drive motor 22 can be activated to cause the transmission spur gear 23 to move the reduction spur gear 24, which in turn drives the circular lens to rotate through the hollow shaft 17, adjusting the contact position between the circular lens and the coarse grinding disc 13, and achieving edge trimming at different positions of the circular lens.

[0059] After coarse grinding, the electric push rod 10 is activated to pull the displacement plate 9 upward, so that the coarse grinding disc 13 moves away from the round lens while the fine grinding disc 12 moves closer to the round lens. When the fine grinding disc 12 contacts the round lens, the drive motor 15 is activated to drive the fine grinding disc 12 to rotate, so as to refine the edge of the round lens through the fine grinding disc 12.
