[0051] S10. The matching mold unit 300 matches a plurality of upper molds and lower molds having various degrees or models in the mold carrier 200;

[0052] S20. The carrier transmission unit 400 drives the mold carrier 200 equipped with the mold after mold matching to be transmitted; the tray conveying unit 900 drives the tray to be conveyed along the conveying direction of the mold carrier 200;

[0053] S30. The plurality of tray-swinging robot arms 600 classify the paired molds in the mold carrier 200 according to the same degree or model and place them in the tray of the tray conveying unit 900 .

[0054] In actual use of the present invention, multiple upper molds and lower molds are placed in the mold carrier 200 after being matched by the matching mold unit 300, and the upper and lower molds are quickly matched and enter the mold carrier, thereby improving the mold matching efficiency; the carrier transmission unit 400 continuously transmits a plurality of mold carriers 200 carrying molds after mold closing, thereby improving the turnover efficiency and reducing unnecessary turnover and transportation; during the transmission process, multiple swing plate robotic arms 600 arranged along the conveying direction of the carrier transmission unit 400 sort and place different molds in the mold carrier 200, thereby improving the sorting and placement efficiency.

[0055] The present contact lens mold classification and plating method has a compact overall layout structure, and integrates a matching mold unit and a carrier transmission unit in the placement and sorting process, providing continuous and stable material feeding for the classification and plating action; realizing rapid mold closing and placement and collection of contact lens upper and lower molds after processing; shortening the overall turnover process, reducing time and equipment costs, and improving the overall production and processing efficiency.

[0056] In this embodiment, the matching mold clamping unit 300 further includes an upper mold material guiding mechanism 320, a lower mold material guiding mechanism 330 and a mold clamping mechanism 340;

[0057] In step S10, it also includes:

[0058] S11. The upper mold guide mechanism 320 receives a plurality of upper molds having various degrees or models and moves the materials to the upper mold loading location;

[0059] S12. The lower mold guide mechanism 330 receives multiple lower molds with various degrees or models and moves them to the loading position of the lower mold;

[0060] S13. The mold clamping mechanism 340 moves the lower mold from the loading position of the lower mold to the mold carrier 200; then the mold clamping mechanism 340 moves the upper mold from the loading position of the upper mold to the mold carrier 200, and places the upper mold in the lower mold with the same degree or model as the upper mold, so as to achieve the matching and clamping of multiple upper and lower molds.

[0061] The upper mold material guide mechanism 320 and the lower mold material guide mechanism 330 are used to receive and transfer the upper mold. A single receiving and operation can realize the simultaneous operation of multiple molds. After the upper mold material guide mechanism 320 and the lower mold material guide mechanism 330 simultaneously transfer the upper mold and the lower mold to the loading position, the mold clamping mechanism 340 first places the lower mold in the mold carrier 200, and then places the upper mold in the lower mold to complete the matching and clamping. The placement position of the mold on the mold carrier 200 corresponds to the distribution position of the mold picked up by the upper mold material guide mechanism 320, the lower mold material guide mechanism 330 and the execution end of the clamping mechanism 340. The overall structure is streamlined to realize integrated upper and lower mold loading and reduce the mold turnover path. Then, the clamping mechanism is set to quickly match and clamp the upper and lower molds, reduce further turnover and transmission, complete rapid mold matching, and save the time, economic and labor costs caused by long-distance turnover as a whole, thereby improving the overall production and processing efficiency.

[0062] Specifically, the upper mold material guiding mechanism 320, the lower mold material guiding mechanism 330 and the mold closing mechanism 340 are all installed on the mold closing bracket 310; the mold closing bracket 310 includes a front frame 312, a rear frame 313, and a mold closing cross frame 311 mounted on the top of the front frame 312 and the rear frame 313; the upper mold material guiding mechanism 320 is installed on the front frame 312, the lower mold material guiding mechanism 330 is installed on the rear frame 313, and the mold closing mechanism 340 is installed on the mold closing cross frame 311.

[0064] In this embodiment, the upper mold material guiding mechanism 320 includes an upper mold material receiving component 321 for receiving incoming materials from the upper mold and an upper mold moving component 322 for moving the upper mold to the material loading location; after the upper mold material receiving component 321 receives the material from the upper mold, the upper mold moving component 322 moves the upper mold from the upper mold material receiving component 321 to the upper mold material loading location.

The upper die lifting driving device 3211 drives the upper die flipping driving device 3212 to lift and lower. The upper die receiving fixture 3213 places the upper die in the upper die moving assembly 322.

[0068] S112. When the upper mold receiving component 321 receives the incoming material from the upper mold, the upper mold linear drive device 3221 drives the upper mold fixture 3222 to the upper mold receiving tooling 3213 of the upper mold receiving component 321 to wait for the upper mold to be loaded. After the upper mold receiving component 321 has loaded the upper mold, the upper mold linear drive device 3221 drives the upper mold fixture 3222 to the upper mold loading position.

[0069] Among them, the upper mold receiving component 321 is used to receive the upper mold that needs to be closed, and place the upper mold in the upper mold moving component 322, and transport the upper mold to the material loading location; reduce the turnover times, and combine the material receiving and moving conveying actions.

[0075] S132. The mold-closing lifting drive device 343 pushes the mold-closing tooling 344 to lift and pick up the upper mold and the lower mold at the upper mold material guide mechanism 320 or the lower mold material guide mechanism 330, and then the mold-closing linear drive device 341 drives the mold-closing lifting drive device 343 to the upper mold or the lower mold in the mold carrier 200; the mold-closing lifting drive device 343 pushes the mold-closing tooling 344 to lift and place the lower mold in the mold carrier 200 or the upper mold in the lower mold to complete the mold closing.

[0083] When the mold carrier 200 is about to enter the first material transport component 500 from the outlet end of the empty conveying device 420, the second gear driving device 474 drives the second unloading gear 475 to rise and fall, and blocks other mold carriers 200 that are about to flow out of the empty conveying device 420 to prevent other mold carriers 200 from interfering with and colliding with the mold carrier 200 that is about to be transported. The second unloading driving device 472 pushes the second line unloading push plate 471 to push the mold carrier 200 that is about to be transported into the first material transport component 500.
