[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0041] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0042] Example 1

[0043] Reference Figure 1-Figure 3 ,as well as Figure 5 , This embodiment provides a double-sided synchronous processing device for optical lens processing, including a backing platform 1, and an operating table 2 is fixedly installed above the backing platform 1;

[0044] A frame shell 3, the frame shell 3 is fixedly mounted on the operating table 2, and a rear cover 4 is mounted on the back of the frame shell 3, the frame shell 3 and the rear cover 4 are assembled as one piece;

[0045] The dust storage tank box 9 is arranged above the operating table 2. Dust suction fans 10 are installed on both sides of the dust storage tank box 9, so that the dust generated by the polishing and grinding can be quickly sucked while the polishing and grinding operation is in progress. The front and rear ends of the dust storage tank box 9 are fixedly connected with support frames 7. The upper ends of the two support frames 7 are commonly fixedly connected with a mounting ring 8. A silicone pad 801 is arranged in the mounting ring 8 to improve the tightness of the optical lens in the mounting ring 8.

[0046] A lifting mechanism 5 is provided on the operating table 2. The lifting mechanism 5 is used to drive the optical lens fixed in the mounting ring 8 to be lifted and lowered, so that the optical lens can be sent upward between the two polishing brushes 602d in a timely manner for polishing. This does not require a person to hold the optical lens by hand, and provides the possibility of synchronous polishing of both sides of the optical lens; and

[0047] The synchronous polishing mechanism 6 includes a rotating belt assembly 601, a side polishing assembly 602, a push-fit assembly 603 and a travel switch 604. The number of the side polishing assemblies 602 is two, which are symmetrically arranged on the left and right. The rotating belt assembly 601 is arranged in the middle of the two side polishing assemblies 602. The rotating belt assembly 601 can be used to synchronously drive the two side polishing assemblies 602 pushed together by the push-fit assembly 603, thereby synchronously polishing and grinding the two sides of the optical lens.

[0048] Specifically, refer to Figure 2 , Figure 3 The lifting mechanism 5 includes a servo motor 501, an internal threaded sleeve 502, a threaded rod 503 and a connecting seat 504. The servo motor 501 is fixedly installed on the bottom side of the operating table 2. The threaded rod 503 vertically penetrates the operating table 2 and is rotatably installed in the operating table 2. The lower end of the threaded rod 503 is fixedly connected to the output end of the servo motor 501. The internal threaded sleeve 502 is threadedly sleeved outside the threaded rod 503. The connecting seat 504 is fixedly installed on the internal threaded sleeve. On the outside of the tube 502, the side of the connecting seat 504 away from the internal threaded sleeve 502 is fixedly connected to the end face of the dust storage tank box 9; the output end of the servo motor 501 drives the threaded rod 503 to rotate, and the internal threaded sleeve 502 can be lifted and lowered by switching the forward and reverse states of the threaded rod 503, so that the dust storage tank box 9 connected to the internal threaded sleeve 502 and the mounting ring 8 on the dust storage tank box 9 can be flexibly lifted and lowered, thereby realizing the delivery of the optical lens between the two polishing brushes 602d.

[0049] Further, see Figure 2 , Figure 3 The lifting mechanism 5 further includes a first slide rail 505 and a slide rod 506. The first slide rail 505 and the slide rod 506 are both symmetrically arranged. The two first slide rails 505 are respectively fixedly embedded on both sides of the frame shell 3, and the two slide rods 506 are respectively slidably inserted into the two first slide rails 505;

[0050] The opposite ends of the two slide bars 506 are fixedly connected to the connecting seat 504, and the two slide bars 506 are inserted into the two first slide rails 505, so as to ensure that the dust storage tank box 9 and the internal threaded sleeve 502 can only be vertically translated along the height direction of the threaded rod 503, and ensure that the two dust storage tank boxes 9 can only be directly raised and lowered, and the extended upper ends of the two slide bars 506 are installed with arc plates 507. After the dust storage tank box 9 and the mounting ring 8 are raised to a high position, the arc plates 507 can press the travel switch 604, so as to prompt the transfer belt assembly 601, the side throwing assembly 602, and the push-to-close assembly 603 to start, and perform the polishing operation on the optical lens sent between the two polishing brushes 602d.

[0051] Operation process: When in use, the optical lens is placed in the mounting ring 8, and then the servo motor 501 is started to drive the threaded rod 503 to rotate, so as to realize the lifting of the internal threaded sleeve 502 and the dust storage box 9. After the mounting ring 8 and the optical lens inside are moved between the two polishing brushes 602d, the pushing assembly 603 pushes the two side polishing assemblies 602 toward the middle, and then the rotating belt assembly 601 is started to drive the two polishing brushes 602d in the two side polishing assemblies 602 to perform synchronous polishing treatment on the two sides of the optical lens.

[0052] Example 2

[0053] Reference Figure 2-Figure 4 , based on the first embodiment, this embodiment is different from the first embodiment in that: the side-casting assembly 602 includes a mounting plate 602a, a driven gear plate 602b, a fixed plate 602c and a polishing brush 602d, a short shaft 602e connecting the fixed plate 602c and the driven gear plate 602b is provided between the fixed plate 602c and the driven gear plate 602b, the polishing brush 602d is fixedly mounted on a side of the fixed plate 602c away from the short shaft 602e, and one end of the short shaft 602e away from the fixed plate 602c is fixedly connected to the end surface of the driven gear plate 602b;

[0054] A first rotating ring 602f is rotatably mounted in the mounting plate 602a, and at least two telescopic rods 602h are circumferentially mounted on the end surface of the first rotating ring 602f. One end of the plurality of telescopic rods 602h close to the driven gear plate 602b is commonly fixedly connected to a second rotating ring 602g, and the second rotating ring 602g is fixedly connected to the end surface of the driven gear plate 602b away from the short axis 602e; the first rotating ring 602f ensures that the driven gear plate 602b and the polishing brush 602d can be rotatably arranged on the side of the frame shell 3, and the telescopic rod 602h and the tension spring 602i ensure that the interval between the driven gear plate 602b and the frame shell 3 can be flexibly adjusted, so as to achieve the purpose of pressing and releasing the polishing brush 602d against the side of the optical lens while ensuring the rotation characteristics of the driven gear plate 602b and the polishing brush 602d;

[0055] Each telescopic rod 602h is sleeved on the outside of the tension spring 602i, and both ends of each tension spring 602i are fixedly connected to the corresponding end surface of the second rotating ring 602g and the end surface of the first rotating ring 602f respectively.

[0056] Specifically, the belt assembly 601 includes a driving motor 601a, a rotating shaft 601b and a long active gear 601c. The rotating shaft 601b is transversely rotatably installed in the frame shell 3. The driving motor 601a is fixedly installed on the side of the frame shell 3. The output end of the driving motor 601a is fixedly connected to the end of the rotating shaft 601b. The long active gear 601c is fixedly sleeved outside the middle of the rotating shaft 601b. After the two driven gear plates 602b in the two side polishing assemblies 602 are translated to the position where the long active gear 601c is engaged, the driving motor 601a is started to drive the long active gear 601c. The rotation of the long active gear 601c can synchronously drive the two driven gear plates 602b, so that the two sides of the optical lens can be synchronously polished.

[0057] The push-to-close assembly 603 includes a sliding block 603a and a second slide rail 603b. The number of the sliding blocks 603a is set to two, and the two sliding blocks 603a are respectively slidably installed at the two ends of the second slide rail 603b. The two sliding blocks 603a move closer to the middle, which can push the two driven gear plates 602b toward the middle, causing the two polishing brushes 602d to respectively rest on the two sides of the optical lens.

[0058] Furthermore, the number of the travel switches 604 is two, which are symmetrically arranged on both sides of the frame shell 3, and the two travel switches 604 are respectively installed on the two side surfaces of the frame shell 3, and the two travel switches 604 are respectively located directly above the two arc plates 507, so that the two arc plates 507 press the two travel switches 604 respectively, and then the subsequent start-up actions of the belt transfer assembly 601, the side throwing assembly 602 and the push-to-close assembly 603 can be triggered, thereby reducing the probability of false touch and false operation;

[0059] The second slide rail 603b is an electrically driven slide rail, and the two slide blocks 603a can be actively displaced after being controlled in the second slide rail 603b.

[0060] The rest of the structure is the same as that of Example 1.

[0061] Operation process: When in use, the two sliding blocks 603a move toward the middle, which can push the two driven gear plates 602b toward the middle, causing the two polishing brushes 602d to respectively rest against the two sides of the optical lens. After that, the two driven gear plates 602b in the two side polishing assemblies 602 are translated to the position where the active long gear 601c is engaged, and the driving motor 601a is started to drive the active long gear 601c. The rotation of the active long gear 601c can synchronously drive the two driven gear plates 602b, thereby synchronously polishing the two sides of the optical lens.
