In addition, traditional fixing devices often cannot adapt to optical lenses of different shapes and sizes, resulting in low flexibility and versatility. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] See also Figure 1-4, an optical lens thickness detection device that is easy to adjust, comprising a base 1, a laser scanner 2, an adjustment device and a fixing device, a detection table 3 is installed on the top of the base 1, a support plate 4 is installed on the rear end of the top wall of the base 1, a top seat 5 is installed on the top of the support plate 4, and the bottom end of the top seat 5 is installed with the laser scanner 2 through the adjustment device, the adjustment device comprises a first trough 6, a first slider 7, a first screw 8, a first motor 9, a moving plate 10, a second trough 11, a second screw 12, a second slider 13 and a second motor 14, the bottom wall of the base 1 is transversely provided with the first trough 6, the first screw 8 is rotatably installed in the first trough 6, the first slider 7 The first motor 9 is installed on the side wall of the top seat 5 at one end, the first slider 7 is threadedly installed on the first screw 8, the movable plate 10 is longitudinally installed on the bottom end of the first slider 7, the bottom end of the movable plate 10 is provided with the second slot 11, the second screw 12 is installed in the second slot 11, one end of the second screw 12 passes through the side wall of the movable plate 10 and is installed with the second motor 14, the second slider 13 is threadedly installed on the second screw 12, and the bottom end of the second slider 13 is installed with the laser scanner 2. In this embodiment, when it is needed to inspect the thickness of the optical lens during use, the optical lens is first placed on the inspection table 3, and then The fixing device fixes the optical lens on the detection table 3, and then starts the laser scanner 2 to detect the thickness of the optical lens. The laser scanner 2 will emit a laser beam to scan the lens to measure its thickness. In this process, the laser scanner 2 will capture the reflected light on the surface of the lens and calculate the thickness of the lens according to the characteristics of the reflected light. When it is necessary to detect the thickness of different positions on the optical lens, the first motor 9 is started, and the output end of the first motor 9 drives the first screw 8 to rotate. During the rotation process, the first screw 8 drives the first slider 7 to move linearly in the first slot 6, driving the moving plate 10 and the laser scanner to adjust the lateral position. By adjusting the rotation direction and speed of the first motor 9, the The moving direction and distance of the laser scanner 2 can then be driven by the second motor 14 to rotate the second screw 12, so that the second slider 13 moves in the second trough 11. Since the second slider 13 is connected to the laser scanner 2, this will drive the laser scanner 2 to move in the longitudinal position. By adjusting the rotation direction and speed of the second motor 14, the laser scanner 2 can be accurately controlled to adjust the longitudinal position. After adjusting the position of the laser scanner 2, the thickness detection continues. The laser scanner 2 will record the thickness data of each measuring point. After the detection is completed, the collected data can be processed and analyzed by the data processing system connected to the detection device to evaluate parameters such as the thickness distribution and uniformity of the lens.
[0027] In actual use, it is further convenient to fix optical lenses of different models. In this embodiment, the fixing device includes a third slot body 15, a bidirectional screw 16, a moving block 17, a connecting rod 18, a clamping block 19 and a third motor 20. The side wall of the support plate 4 close to the detection platform 3 is provided with the third slot body 15, and the bidirectional screw 16 is rotatably installed in the third slot body 15. One end of the bidirectional screw 16 passes through the side wall of the support plate 4 and is installed with the third motor 20. The moving blocks 17 are threadedly installed on both ends of the bidirectional screw 16, and the connecting rod 18 is installed at the ends of the two groups of moving blocks 17 away from each other. The connecting rod 18 is away from the moving blocks 17. One end of the clamping block 19 is connected to the clamping block 19. When the optical lens needs to be fixed, the optical lens is first placed on the testing table 3, and then the third motor 20 is started to rotate forward. The output end of the third motor 20 drives the bidirectional screw 16 to rotate. As the bidirectional screw 16 rotates, due to the threaded connection, the two groups of moving blocks 17 will move relative to each other along the axial direction of the bidirectional screw 16. As the moving blocks 17 move, they will drive the clamping blocks 19 to approach each other through the connecting rod 18, so that they can accurately and firmly clamp the optical lens while avoiding damage to the lens. By changing the rotation direction of the third motor 20, the moving block 17 can be controlled to approach or move away, so as to achieve clamping, fixing or unlocking of the clamping block 19.
[0028] Preferably, in this embodiment, a V-groove 21 is provided on one side corresponding to the two groups of clamping blocks 19. The design of the V-groove 21 enables the optical lens to be more easily positioned and fixed by the clamping block 19. The structure of the V-groove 21 helps to provide a uniform clamping force distribution during the clamping process. This design can reduce the shaking or displacement of the optical lens during the clamping process, thereby improving the stability of the overall structure. During the assembly or detection process, this helps to improve the detection efficiency and reduce errors.
[0029] Preferably, in this embodiment, the two groups of clamping blocks 19 are slidably connected to the top wall of the testing platform 3, so that the clamping blocks 19 can move more smoothly and fluently on the testing platform 3.
[0030] In actual use, the stability and accuracy of the operation of multiple groups of electrical devices are further guaranteed. In this embodiment, the first motor 9, the second motor 14 and the third motor 20 are all servo motors. The servo motors can control the position, speed and torque with high precision. The servo motors use closed-loop control and have good stability. They can avoid problems such as stalling and vibration, thereby ensuring the stability and accuracy of the operation of the first motor 9, the second motor 14 and the third motor 20.
[0031] Preferably, in this embodiment, the first slot body 6 and the second slot body 11 are both of rectangular design, and the rectangular design facilitates guiding the first slider 7 and the second slider 13 to prevent the first slider 7 and the second slider 13 from self-rotating.
[0032] In actual use, in order to further ensure the support stability of the base 1, in this embodiment, support legs 22 are installed at the four corners of the bottom end of the base 1. The support legs 22 allow the supporting force of the base 1 to be evenly distributed, thereby preventing excessive force on a single point from causing the base 1 to tilt or deform. The design of evenly distributing the supporting force makes the base 1 more stable and able to withstand greater weight and impact.
[0033] In actual use, in order to further ensure the support stability of the support leg 22, in this embodiment, a rubber pad is installed on the bottom wall of the support leg 22, and the surface of the rubber pad has a certain friction coefficient, which can provide good anti-slip performance. When the support leg 22 is placed on the ground or other flat surfaces, the rubber pad can effectively prevent the support leg 22 from sliding or shifting due to external force or vibration, thereby ensuring the stability of the support structure.
