[0051] S10. The matching clamping unit 300 pairs several upper 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 pairing after the mold is transmitted; the tray conveying unit 900 drives the tray along the conveying direction of the mold carrier 200;

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

[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 entered into the mold carrier, thereby improving the mold matching efficiency; the carrier transmission unit 400 continuously transmits a number of mold carriers 200 carrying molds after mold closing, thereby improving 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] This contact lens mold classification and plating method has a compact overall layout and structure, and integrates a matching mold clamping unit and a carrier transmission unit in the placement and sorting process, providing continuous and stable material feeding for the classification and plating action; it realizes rapid mold clamping and material placement and collection after the contact lens upper and lower molds are processed; it shortens the overall turnover process, reduces time and equipment costs, and improves 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 material to the upper mold loading area;

[0059] S12. The lower mold guide mechanism 330 receives multiple molds of various sizes or models and moves the mold to the loading area 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 of the same degree or model as the upper mold 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 guide mechanism 330 simultaneously transfer the upper mold and the lower mold to the loading position, the mold closing 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 closing of the molds. 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 mold closing mechanism 340. The overall structure is streamlined, and the loading of the upper and lower molds is realized in an integrated manner, reducing the mold turnover path. The upper and lower molds are quickly matched and closed by setting up a mold closing mechanism, which reduces further turnover and transmission, completes fast mold closing and pairing, and saves the time, economy and labor costs brought 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 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 loading location.

After the upper mold receiving fixture 3213 receives the material and secures the upper mold, the upper mold flipping drive 3212 rotates the upper mold receiving fixture 3213 toward the upper mold moving assembly 322. The upper mold lifting drive 3211 drives the upper mold flipping drive 3212 to rise and fall, and the upper mold receiving fixture 3213 places the upper mold into the upper mold moving assembly 322.

[0068] S112. When the upper mold receiving assembly 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 assembly 321 to wait for the upper mold to be loaded. After the upper mold receiving assembly 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 loading location; reduce the turnover times, and combine the material receiving and moving conveying actions.

The other mold-closing lifting drive device 343 and the mold-closing fixture 344 to reciprocate between the lower mold guide mechanism 330 and the mold carrier 200.

[0075] S132. The mold closing lifting drive device 343 pushes the mold closing tooling 344 to lift and lower 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 lower the lower mold to 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, blocking 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, and 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.
