[0026] Compared with the prior art, the invention has the following beneficial effects: the quick-clamping lens thickness detector adopts a new structural design, and its specific contents are as follows:

[0027] (1) During the working process of the quick-clamping lens thickness detector, when clamping the lens, the lens is inserted into the installation groove so that the other side of the lens is located in the auxiliary groove. At this time, the lens pushes the squeezing plate, so that the squeezing plate squeezes the first spring through the cross bar. Then, under the action of the cross bar and the first spring, the squeezing plate always has a tendency to move toward the lens, and then the squeezing plate supports the lens to keep the lens stable.

[0028] Furthermore, when it is necessary to clamp other lenses, the same steps can be followed to clamp them. The operation process is quick and convenient, which improves the work efficiency of the staff.

[0029] (2) After the lens is clamped, the motor of the quick-clamping lens thickness detector is started, and the motor drives the long pin to rotate. Then, the movable block moves on the surface of the base under the action of the long pin and the limit rod. The movable block drives the connecting rod and the optical detector to move synchronously. At this time, the optical detector can detect the lens inside the base;

[0030] Furthermore, when the optical detector detects unqualified products, the electric telescopic rod is activated, and the electric telescopic rod drives the push block to move toward the lens, and finally the push block pushes the lens out of the installation slot, that is, the push block pushes the lens out of the lens queue, so that the staff can find out the unqualified products in time;

[0031] Furthermore, at the output end of the electric telescopic rod, when the push block is driven to move, the output end of the electric telescopic rod simultaneously drives the connecting shaft to rotate on the surface of the fixed plate through the traction rope. At this time, the first magnet on the surface of the disc will intermittently approach the second magnet on the surface of the movable plate, that is, the movable plate is intermittently subjected to mutually repulsive magnetic forces. At this time, the movable plate makes reciprocating linear motion in the horizontal direction under the action of the mutually repulsive magnetic forces, the overlap block, the limiting rod and the second spring. At this time, the knocking rod will hit the copper sheet again and again, causing the copper sheet to make a sound, so that the staff can notice the appearance of defective products. The copper sheet that makes the sound cooperates with the push block, so that the staff can not only notice the appearance of defective products in time, but also find the specific location of the defective products in time, thereby improving the work efficiency of the staff.

[0046] A quick-clamping lens thickness detector, further comprising:

[0047] The motor 4 is bolted to the outer wall of the base 1, and the output end of the motor 4 is fixedly connected with a long pin 5, and the outer surface of the base 1 is fixedly connected with an auxiliary block 6, and the inner part of the base 1 is slidably provided with an extrusion plate 12;

[0048] A movable block 8, the movable block 8 is sleeved and connected to the surface of the long pin 5, and the upper surface of the movable block 8 is fixedly connected to a connecting rod 9, and the lower surface of the connecting rod 9 is fixedly connected to an optical detector 11;

[0049] A fixing plate 10, the fixing plate 10 is fixedly connected to the surface of the connecting rod 9, and the surface of the fixing plate 10 is bolted with an electric telescopic rod 15, and the surface of the fixing plate 10 is fixedly connected with a copper sheet 26, and the electric telescopic rod 15 and the optical detector 11 are connected for electrical signals;

[0050] A transition shaft 18, the transition shaft 18 is fixedly connected to the surface of the fixed plate 10, and a connecting shaft 17 is rotatably arranged inside the fixed plate 10;

[0051] The overlapping block 27 is slidably arranged inside the fixed plate 10, and the surface of the overlapping block 27 is fixedly connected with the movable plate 22, and the surface of the movable plate 22 is fixedly connected with the knocking rod 24 and the copper sheet 26, and the copper sheet 26 is fixedly connected to the surface of the fixed plate 10.

[0052] A cross bar 13 is fixedly connected to the side of the extrusion plate 12, and the extrusion plate 12 is arranged inside the mounting groove 2, and the surface of the cross bar 13 is in contact with the inner wall of the base 1, the upper surface of the extrusion plate 12 is inclined, and a first spring 14 that plays an elastic reset role is fixedly connected to the surface of the cross bar 13, and the other side of the first spring 14 is fixedly connected to the inner wall of the base 1.

[0053] During the working process, when clamping the lens, the lens is inserted into the installation groove 2 so that the other side of the lens is located in the auxiliary groove 3. At this time, the lens will push the squeezing plate 12, so that the squeezing plate 12 squeezes the first spring 14 through the cross bar 13, and then the squeezing plate 12 always has a tendency to move toward the direction of the lens under the action of the cross bar 13 and the first spring 14, and then the squeezing plate 12 supports the lens to keep the lens stable. At the same time, the remaining lenses can be clamped through the same steps. The operation process is quick and convenient, which improves the work efficiency of the staff.

[0054] Embodiment 2: By setting the electric telescopic rod 15 and the push block 16, unqualified lenses can be quickly pushed out of the lens queue, so that the staff can notice the location of unqualified products. Figure 1 , Figure 2 and Figure 4 As shown:

[0055] The long pin 5 and the movable block 8 are threadedly connected, and the end of the long pin 5 is rotatably set inside the auxiliary block 6. The connecting rod 9 is an inverted "L" structure. The outer surface of the base 1 is fixedly connected to the limiting rod 7, and the limiting rod 7 runs through the inside of the connecting rod 9, and the limiting rod 7 is an inverted "U" shape.

[0056] The end of the output end of the electric telescopic rod 15 is fixedly connected to a push block 16 , and the side of the output end of the electric telescopic rod 15 is fixedly connected to a traction rope 19 , and the other side of the traction rope 19 is wound and fixedly connected to the surface of the connecting shaft 17 .

[0057] After the lens is clamped, the motor 4 is started, and the motor 4 drives the long pin 5 to rotate, and then the movable block 8 moves horizontally on the surface of the base 1 under the action of the long pin 5 and the limit rod 7. When the movable block 8 moves, it drives the connecting rod 9, the fixed plate 10 and the optical detector 11 to move synchronously. At this time, the optical detector 11 can detect the lens inside the base 1. When the optical detector 11 detects unqualified products, the electric telescopic rod 15 is started. At this time, the output end of the electric telescopic rod 15 drives the push block 16 to move toward the direction of the lens. Finally, the push block 16 pushes the lens out of the installation slot 2, that is, the push block 16 pushes the lens out of the lens queue, which is convenient for the staff to find out the unqualified products in time.

[0058] Embodiment 3: Different from Embodiment 2, the copper sheet 26 is provided to allow the staff to quickly notice the presence of defective products, making it easier for the staff to remove the defective products. Figure 5-Figure 8 As shown:

[0059] The connecting shaft 17 is symmetrically distributed about the center of the fixed plate 10, and a disc 20 is fixedly connected to the surface of the connecting shaft 17, and a first magnet 21 is fixedly connected to the surface of the disc 20, and the first magnets 21 are distributed at equal angles on the surface of the disc 20. A second magnet 23 corresponding to the first magnet 21 is inlaid on the surface of the movable plate 22, and the second magnet 23 has the same magnetic pole as the first magnet 21 at an adjacent position.

[0060] A limiting rod 28 is fixedly connected to the inner wall of the fixed plate 10, and the limiting rod 28 passes through the inside of the overlapping block 27, and a protective frame 25 is fixedly connected to the surface of the fixed plate 10, and a second spring 29 is fixedly connected to the surface of the overlapping block 27, and the other side of the second spring 29 is fixedly connected to the inner wall of the fixed plate 10.

[0061] When the output end of the electric telescopic rod 15 drives the push block 16 to move, the output end of the electric telescopic rod 15 drives the connecting shaft 17 to rotate on the surface of the fixed plate 10 through the traction rope 19 (the transition shaft 18 maximizes the pulling force of the traction rope 19). When the connecting shaft 17 rotates, the disc 20 is driven to rotate synchronously. At this time, the first magnet 21 on the surface of the disc 20 will intermittently approach the second magnet 23 on the surface of the movable plate 22. When the first magnet 21 approaches the second magnet 23, the movable plate 22 and the overlap block 27 move in the direction of squeezing the second spring 29, and when the first magnet 21 is away from the second magnet 2 3, the movable plate 22 and the lap block 27 return to their original positions under the action of the second spring 29 (the limiting rod 28 makes the lap block 27 move more stably), and the above process is repeated, that is, the movable plate 22 and the knocking rod 24 make reciprocating linear motion in the horizontal direction. At this time, the knocking rod 24 will hit the copper sheet 26 again and again, making the copper sheet 26 make a sound, so that the staff will notice the appearance of defective products. The copper sheet 26 that makes a sound cooperates with the push block 16, so that the staff can not only notice the appearance of defective products in time, but also find the specific location of the defective products in time, thereby improving the work efficiency of the staff.

[0062] Embodiment 4: Different from Embodiment 3, the copper sheet 26 can work stably by providing a protective frame 25. Figure 4 As shown:

[0063] The copper sheet 26 is symmetrically distributed about the center of the fixed plate 10, and the copper sheet 26 corresponds to the knocking rod 24 one by one, and the copper sheet 26 is arranged inside the protective frame 25, and the protective frame 25 is a mesh structure. The surface of the connecting shaft 17 is fixedly connected with a torsion spring 30 which plays an elastic reset role, and the other side of the torsion spring 30 is fixedly connected to the inner wall of the fixed plate 10.

[0064] When the connecting shaft 17 rotates, the torsion spring 30 will be stretched, and then move back at the output end of the electric telescopic rod 15. When the connecting shaft 17 loses the pulling force of the traction rope 19, the connecting shaft 17 will rotate under the action of the torsion spring 30, which is convenient for the next use. When the copper sheet 26 is working, the mesh structure protection frame 25 prevents the copper sheet 26 from making false sounds, and also ensures the propagation of sound.

[0065] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
