[0037] The following description provides many different embodiments, or examples, for implementing different features of the application. Specific examples are described in the following detail so as to provide a thorough understanding of the application. The description and drawings are not intended to limit the application to the described embodiments, but to serve as an example to enable others to make and use the application.

[0038] For the purpose of clarity, technical solutions in the embodiments of the present application will be described below in a clear and complete manner with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed application, but only to represent selected embodiments of the present application.

[0039] In the present application, unless specifically defined and limited otherwise, the terms "mount", "connected", "connection", "fixed", and the like, should be understood broadly, for example, can be fixed connection, can also be detachable connection, or integral; can be mechanical connection, can also be electrical connection; can be directly connected, can also be indirectly connected through an intermediate medium, can be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0040] In the present application, unless specifically defined and limited otherwise, the first feature above or below the second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, the first feature above, above and above the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature below, below and below the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0041] In current optical inspection platforms, different sizes of clamps are required for optical lenses with different diameters. The clamps are also large and inconvenient to operate. When the clamps are used to hold optical lenses, they are prone to jamming and cannot be held.

[0042] In view of this, the first aspect of this application provides a laser optical lens clamping assembly, such as Figures 1-7 As shown, it includes: an upper rotating member 21, a clamp base 23, a clamp 22, and a lower rotating member 24;

[0043] The upper rotating member 21 is located above the lower rotating member 24, and the upper rotating member 21 and the lower rotating member 24 are rotatably mounted in the mounting cavity 231 of the clamp base 23;

[0044] The upper rotating member 21 and the lower rotating member 24 are fixedly connected. For example, the upper rotating member 21 is fixedly connected to the lower rotating member 24 by a cylindrical head screw 213, so that the upper rotating member 21 and the lower rotating member 24 can rotate simultaneously in the clamp base 23. The rotating end of the clamp 22 extends between the upper rotating member 21 and the lower rotating member 24, and the rotating end of the clamp 22 is located in the gap between the upper rotating member 21 and the lower rotating member 24. In this way, the clamp 22 can rotate along the same horizontal plane when rotating, so that when the clamp 22 clamps the optical lens 25, the force acting on the optical lens 25 is located on the same horizontal plane, the optical lens 25 remains in the horizontal direction and does not tilt, thus ensuring the accuracy of the focal length measurement of the optical lens 25. Along the y-direction, the rotating ends of the upper rotating member 21, the lower rotating member 24, and the clamp 22 are connected in sequence by a positioning member 241. For example, the positioning member 241 is a positioning pin. The positioning pin passes through one end of the clamp 22 and is fixedly connected to the lower rotating member 24, and the other end is fixedly connected to the upper rotating member 21. The rotating end of the clamp 22 can rotate around the positioning member 241. The lower side of the other rotating end of the clamp 22 can slide linearly in the clamp base 23 through the pin 224, converting the linear motion into the curvilinear motion of the clamp 22, which is used to realize the clamping and opening of the clamp 22.

[0045] In operation, this application applies a driving force to the upper rotating member 21, causing the upper rotating member 21 to rotate along a preset direction, thereby driving the lower rotating member 24 to rotate simultaneously. At the same time, the positioning member 241 drives the rotating end of the clamp 22 to slide in the clamp base 23, thereby realizing the clamping end of the clamp 22 to clamp and open the optical lens 25.

[0046] Therefore, the laser optical lens clamping assembly provided in this application includes an upper rotating member 21 and a lower rotating member 24. The upper rotating member 21 and the lower rotating member 24 are fixedly connected to form an integral unit. The integral unit is installed in the mounting cavity 231 of the clamping base 23. The rotating end of the clamp 22 extends between the upper rotating member 21 and the lower rotating member 24, so that the clamp 22 clamps and opens the optical lens 25 on the same horizontal surface. The optical lens 25 remains in the horizontal direction and does not tilt, thus ensuring accurate measurement of the focal length of the optical lens 25.

[0047] According to some optional embodiments, the upper rotating member 21 has a relief groove 211 on the side adjacent to the lower rotating member 24. The relief groove 211 communicates with the mounting cavity 231, and the rotating end of the clamp 22 is located in the relief groove 211. When the clamp 22 is opened, the clamp 22 can be located in the relief groove 211, which realizes that it can be opened to a preset angle without interfering with the upper rotating member 21, and greatly reduces the volume of the clamp assembly.

[0048] According to some optional embodiments, the clamp 22 includes a rotating arm 221 and a clamping post 222. One end of the rotating arm 221, i.e., the rotating end of the rotating arm 221, is rotatably connected to the positioning member 241, and the other end of the rotating arm 221, i.e., the clamping end of the rotating arm 221, is fixedly connected to the clamping post 222. For example, the upper surface of the clamping end of the rotating arm 221 is detachably connected to the clamping post 222, such as by threaded connection or snap-fit, to facilitate the inspection and replacement of the clamping post 222. Furthermore, a positioning ring 223 is sleeved on the clamping post 222, and the optical lens 25 can be placed on the positioning ring 223, realizing the positioning of the optical lens 25 in the clamp 22 and preventing the optical lens 25 from shifting relative to the clamping post. For example, the positioning ring 223 can be made of soft materials such as rubber to avoid scratching the optical lens 25. When clamping, the clamp 22 first contacts the lower part of the optical lens 25 with the upper part of the positioning ring 223 to make the optical lens 25 horizontal, indicating that the optical lens 25 is in place. At this time, the clamp 22 begins to clamp, and the upper part of the positioning ring 223 slowly moves along the lower part of the optical lens 25 to achieve clamping of the optical lens 25.

[0049] According to some alternative embodiments, a drive element 26 is detachably mounted on the upper rotating member 21.

[0050] In the above scheme, a driving component 26 is installed on the upper surface of the upper rotating component 21. The driving component 26 is a driving rod. By rotating the driving rod from above, the upper rotating component 21 and the lower rotating component 24 can be driven to rotate, thereby clamping and opening the optical lens 25.

[0051] The drive component 26 can be connected to the upper rotating component 21 by screws, snap-fit, or other means, making it easy to install and replace.

[0052] According to some optional embodiments, the clamp base 23 is provided with a reset groove 232, which is a circular groove. A positioning pin 234 is fixedly installed in the reset groove 232, and a reset spring 233 is installed in the reset groove 232. One end of the reset spring 233 is fixedly connected to the positioning pin 234 in the reset groove 232, and the positioning pin 234 is fixed in the reset groove 232. The other end is fixedly connected to the upper rotating member 21. For example, the other end of the reset spring 233 is connected to the lower end of the upper rotating member 21 through a limiting post 212. When the clamp 22 is in the open state, after the optical lens 25 is placed, the force of the driving member 26 acting on the upper rotating member 21 is removed. Under the action of the reset spring 233, the upper rotating member 21 rotates in the opposite direction to the open state of the clamp 22, automatically clamping the optical lens 25 without manually rotating the clamp 22. According to some optional embodiments, the clamp base 23 is provided with a sliding groove 235, which extends radially along the clamp base 23. The other part of the rotating end of the clamp 22 is inserted into the sliding groove 235 via a pin 224 and slides within the sliding groove 235. Exemplarily, when a force is applied to the upper rotating member 21 by the driving member 26, causing the clamp 22 to open, the upper rotating member 21 and the lower rotating member 24 rotate simultaneously, driving the pin 224 at the rotating end of the clamp 22 to move away from the upper rotating member 21 within the sliding groove 235, thereby opening the clamp 22. When the force applied to the upper rotating member 21 is removed, the pin 224 at the rotating end of the clamp 22 moves towards the upper rotating member 21 within the sliding groove 235, thereby clamping the clamp 22.

[0053] According to some optional embodiments, a first limiting groove 236 is provided on one side of the clamp base 23, and the driving member 26 is located in the first limiting groove 236. Exemplarily, the first limiting groove 236 extends along the movement direction of the driving member. One end of the driving member 26 passes through the first limiting groove 236 and is connected to the upper rotating member 21, while the other end extends out of the first limiting groove 236. The extended end of the driving member 26 acts to cause the driving member 26 to rotate within the first limiting groove 236, thus limiting the driving range of the driving member 26 and allowing the driving member 26 to move within a preset stroke. This avoids the clamp 22 opening being too large, which could cause jamming, and the clamp 22 clamping too tightly, which could damage the optical lens 25.

[0054] According to some optional embodiments, the clamp base 23 is provided with a second limiting groove 237, which is nested in the reset groove 232. The shape of the second limiting groove 237 matches the shape of the reset groove 232. The upper rotating member 21 slides in the second limiting groove 237 via a limiting post 212. The setting of the second limiting groove 237 restricts the rotation stroke of the upper rotating member 21, avoiding damage to the reset spring 233 and the optical lens 25 caused by excessive or insufficient rotation.

[0055] The second aspect of this application provides a laser optical lens inspection platform, such as... Figures 6-7 As shown, it includes a collimating lens assembly 10, a beam analysis assembly 30, a slide adjustment assembly 40, and the aforementioned laser optical lens clamp assembly 20.

[0056] In the above scheme, along the y-direction, the collimating lens assembly 10, the laser optical lens clamp assembly 20, and the beam analysis assembly 30 are sequentially mounted on the slide adjustment assembly 40, and the beam analysis assembly 30 can move along the slide adjustment assembly 40.

[0057] The working principle of the laser optical lens inspection platform in this application is as follows: First, the laser beam head is inserted into the collimating lens assembly 10. The incident light is red light. After the red light passes through the collimating lens assembly 10, it forms a cylindrical parallel light. After the cylindrical parallel light passes through the laser optical lens clamp assembly 20, it forms a focused beam. The beam analysis assembly 30 moves in the y-direction of the slide adjustment assembly 40. The beam analysis assembly 30 is used to determine the position of the focal point of the focused beam, thereby obtaining the actual focal length of the optical lens 25 being inspected, and thus quickly screening out optical lenses 25 with large actual focal length deviations.

[0058] According to some alternative embodiments, the beam analysis assembly includes a beam analyzer 31 and a beam analyzer mount 32, wherein the beam analyzer 31 is mounted on the beam analyzer mount 32 and the beam analyzer mount 32 is slidably mounted on the slide adjustment assembly 40.

[0059] In the above scheme, the beam analyzer 31 is moved up and down by the sliding guide rail slider, stopping near the focal length of the optical lens 25 being tested, and then fixed in place by the guide rail clamp 35. Then, the X-axis displacement platform enables fine adjustment, allowing the beam analyzer 31 to accurately find the minimum focal point. At this point, the distance from the optical lens 25 being tested to the beam analyzer 31 is the actual focal length of the optical lens 25.
