[0002] Optical lenses are made of high-purity silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium and other oxides mixed according to a specific formula, melted in a platinum crucible at high temperature, stirred evenly with ultrasound to remove bubbles; then slowly cooled for a long time to prevent the glass block from generating internal stress. The cooled glass block must be measured by optical instruments to check whether the purity, transparency, uniformity, refractive index and dispersion rate meet the specifications. Qualified glass blocks are heated and forged to become optical lens blanks, and then processed and assembled.

[0003] At present, although optical lens assembly technology has achieved a certain degree of automation, there are many assembly steps in the assembly process, especially for high-precision optical components such as RS lenses.

The slide 111 is slidably installed on the reflow channel 3 along the length direction of the reflow channel 3. The fifth cylinder 112 is installed on the reflow channel 3. The piston rod of the fifth cylinder 112 is connected to the slide 111. The plasma cleaning machine 113 is installed on the slide 111.

[0049] When the reflow channel 3 transports the carrier 4 to the plasma cleaning machine 113, the fifth cylinder 112 is started, so that the slide 111 moves along with the transport of the carrier 4 by the reflow channel 3, and the slide 111 drives the plasma cleaning machine 113 to move along with the movement of the carrier 4. The plasma cleaning machine 113 can clean the carrier 4 and the lens materials on the carrier 4, thereby reducing the amount of dust adhering to the carrier 4 and the lens materials, thereby reducing the influence of dust on the processing and assembly of the lens materials and improving the processing quality.

[0050] Reference Figure 6 , Figure 7 The transfer mechanism 8 is installed on the frame 1, and is used to transport the carrier 4 on the recirculation channel 3 to the main flow channel 2. The transfer mechanism 8 includes a support frame 81, a third cylinder 82, a fourth cylinder 83 and a suction cup 84. The support frame 81 is installed on the frame 1, and the support frame 81 spans the main flow channel 2 and the recirculation channel 3. The third cylinder 82 is horizontally installed on the support frame 81, and the fourth cylinder 83 is vertically installed on the piston rod of the third cylinder 82. The suction cup 84 is installed on the piston rod of the fourth cylinder 83, and the suction cup 84 is used to adsorb the carrier 4.

[0051] After the reflux channel 3 transports the carrier 4 from the side of the loading and unloading machine 6 to the side of the assembly station 7 far away from the loading and unloading machine 6, the piston rod of the third cylinder 82 is extended and retracted, driving the fourth cylinder 83 to drive the suction cup 84 to move to just above the carrier 4, and then the piston rod of the fourth cylinder 83 is extended, so that the suction cup 84 moves down and fits onto the carrier 4. After the suction cup 84 adsorbs the carrier 4, the piston rod of the fourth cylinder 83 retracts, and the third cylinder 82 drives the fourth cylinder 83 to move toward the direction close to the main channel 2, so that the fourth cylinder 83 drives the suction cup 84 to move to just above the main channel 2. The piston rod of the fourth cylinder 83 is extended to place the carrier 4 on the main channel 2, and the suction cup 84 releases the adsorption of the carrier 4, so that the carrier 4 loaded with the lens materials to be processed and assembled can be conveniently and quickly loaded onto the main channel 2.

[0052] An RS lens assembly process mainly includes the following steps: S1: The loading and unloading machine 6 takes the lens materials from the material bin 5 to the carrier 4 and transports the carrier 4 from the main flow channel 2 to the return flow channel 3; S2: The reflow channel 3 transports the carrier 4 to the assembly station 7, the cleaning mechanism 11 cleans the carrier 4 and the lens material, and the transfer mechanism 8 transports the carrier 4 from the reflow channel 3 to the main channel 2; S3: the main channel 2 transports the carrier 4 to a plurality of assembly stations 7 in sequence, and the plurality of assembly stations 7 sequentially perform gluing, assembly, curing and testing on the lens materials; S4: the main channel 2 transports the carrier 4 to the loading and unloading machine 6 , and the loading and unloading machine 6 unloads the product onto the unloading tray 52 .

[0053] The implementation principle of an RS lens assembly automatic line and its assembly process in an embodiment of the present application is as follows: a robot 61 takes the lens materials on the silo 5 to the carrier 4 above the main channel 2, and then transfers the carrier 4 to the reflow channel 3; the reflow channel 3 transports the carrier 4 from the side of the loading and unloading machine 6 to the side of the assembly station 7 away from the loading and unloading machine 6; the transfer mechanism 8 transfers the carrier 4 to the main channel 2; the main channel 2 transports the carrier 4 to multiple assembly stations 7 in turn; the multiple assembly stations 7 respectively perform gluing, assembly, curing and inspection on the lens materials; and then the main channel 2 transports the carrier 4 to the loading and unloading machine 6 again; the robot 61 clamps and transfers the processed and assembled products to the silo 5, and clamps and transfers the lens materials to be processed to the carrier 4 again; this reciprocating process can be used to continuously process and assemble the lenses without the need to transfer them multiple times, thereby effectively improving the production efficiency of RS lenses.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
