Description

Technical Field

[0001] This invention relates to the field of mechanical clamping equipment technology, and in particular to a clamping assembly, a lens clamping device, and a lens assembly and adjustment device. Background Technology

[0002] In security equipment, lens modules require calibration fixtures to ensure the installation accuracy between the lens and the sensor board, thereby ensuring the clarity of the lens image.

[0003] Related technologies provide a mechanical gripper for adjustment and a lens assembly device having the same, including a base, a first mounting plate, a second mounting plate, and a gripper assembly. The base is fixedly mounted in an external position, and the gripper assembly is fixed relative to the second mounting plate. The first mounting plate is mounted on the base, and the second mounting plate is mounted on the first mounting plate. The second mounting plate is connected to the first mounting plate via a floating mechanism. The gripper assembly has two degrees of freedom of floating to achieve flexible gripping and can counteract the stress caused by the misalignment of the lens center and the rotation center during adjustment rotation.

[0004] However, in related technologies, the clamping assembly has poor accuracy in fixing the lens position after clamping it, and it is easily affected by external forces, causing displacement and resulting in changes in the image after lens adjustment. Summary of the Invention

[0005] This invention provides a clamping assembly, a lens clamping device, and a lens assembly and adjustment equipment to solve the defects in the prior art where the fixed position accuracy of the lens is poor and it is easily affected by external forces, resulting in changes in the image after lens adjustment. It can improve the precision control of the lens clamping position, thereby ensuring the clarity of the image after lens adjustment.

[0006] This invention provides a clamping assembly, comprising:

[0007] A base, wherein the base is provided with a placement area suitable for placing the object to be clamped;

[0008] A clamping member is disposed on at least one side of the placement area; the clamping member is movably disposed on the base, and a limiting arm is provided at the end of the clamping member facing the placement area, the limiting arm being adapted to abut against the object to be clamped, so as to restrict the degree of freedom of the object to be clamped in a preset direction, the preset direction being the direction away from the base.

[0009] The present invention also provides a lens clamping device, including a base and a clamping assembly as described in any of the foregoing embodiments of the present invention, wherein the clamping assembly is movably disposed on the base; the base is provided with a slide rail and a sliding block, wherein the sliding block is slidably disposed on the slide rail; the sliding block is adapted to connect with the base of the clamping assembly.

[0010] The present invention also provides a lens assembly and adjustment device, including a lens clamping device and a sensor plate clamp as described in any of the foregoing embodiments of the present invention, wherein the sensor plate clamp is located on one side of the lens clamping device.

[0011] This invention provides a clamping assembly, a lens clamping device, and a lens assembly and adjustment equipment. By providing a clamping member on at least one side of the placement area of ​​the base, and a limiting arm on the end of the clamping member facing the placement area, when the lens is placed in the placement area of ​​the base, the limiting arm can abut against the object to be clamped (e.g., the lens) when the clamping member clamps the lens, thereby restricting the lens from moving in the direction away from the base. This prevents the lens position from shifting when subjected to external forces. In other words, when adjusting the position of the lens and sensor plate, it ensures precise control of the lens position, thereby guaranteeing the clarity of the image after lens adjustment and effectively preventing changes in the image after lens adjustment.

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0041] In embodiments of the present invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0043] Lens modules are widely used in security equipment. Typically, lens modules require calibration fixtures to ensure the mounting accuracy between the lens and the sensor board, thereby guaranteeing image clarity. The lens collects reflected light from the object being illuminated, which is then focused onto the photosensitive chip on the sensor board. The sensor board then images the reflected light and converts it into an electrical signal. This places certain requirements on the position between the lens and the sensor board, and some lens modules require calibration fixtures to ensure positional accuracy.

[0044] Related technologies provide a mechanical gripper for adjustment and a lens assembly device having the same, including a base, a first mounting plate, a second mounting plate, and a gripper assembly. The base is fixedly mounted in an external position, and the gripper assembly is fixed relative to the second mounting plate. The first mounting plate is mounted on the base, and the second mounting plate is mounted on the first mounting plate. The second mounting plate is connected to the first mounting plate via a floating mechanism. The gripper assembly has two degrees of freedom of floating to achieve flexible gripping and can counteract the stress caused by the misalignment of the lens center and the rotation center during adjustment rotation.

[0045] However, in related technologies, the clamping assembly has poor accuracy in fixing the lens position after clamping it, and it is easily affected by external forces, causing displacement and resulting in changes in the image after lens adjustment.

[0046] Figure 1This is a schematic diagram of the overall structure of the clamp assembly provided in an embodiment of the present invention. Figure 2 This is an exploded structural diagram of the clamp assembly provided in an embodiment of the present invention.

[0047] Reference Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a clamping assembly 100, including a base 110 and a clamping member 120.

[0048] Specifically, in this embodiment of the invention, the base 110 can be made of sheet metal. It is understood that in some examples, the base 110 can also be made of stainless steel, aluminum alloy, or cast iron; the specific material type of the base 110 is not limited in this embodiment. It is also understood that in some optional examples of this embodiment, the base 110 can be made of other types of materials that are not easily deformed and have a certain degree of hardness. For specific configuration, refer to... Figure 1 and Figure 2 As shown in the embodiment of the present invention, the overall structure of the base 110 can be a sheet structure or a plate structure.

[0049] Continue to refer to Figure 1 and Figure 2 As shown, in this embodiment of the invention, the base 110 is provided with a placement area 111 for placing an object to be clamped. As a specific example, the object to be clamped can be the lens 200 of a lens module. (Refer to...) Figure 1 and Figure 2 As shown, the placement area 111 can be a perforation or groove provided on the base 110, and the lens 200 can be placed in the perforation or groove and clamped and fixed.

[0050] As a specific example of an embodiment of the present invention, the shape of the placement area 111 can be adapted to the external shape of the lens 200. For example, if the overall shape of the lens 200 is square, the placement area 111 can also be set to a square structure; if the overall shape of the lens 200 is circular, the placement area 111 can also be set to a circular structure. In this way, the position of the lens 200 can be initially located by the sidewall of the placement area 111 (e.g., the sidewall of the perforation, or the sidewall of the groove). It should be noted here that, referring to... Figure 1 and Figure 2 As shown, the initial positioning of the lens 200 by the placement area 111 can refer to positioning along the horizontal direction, for example... Figure 1 and Figure 2 The positioning in the x and y directions is shown in the figure; for lens 200 in Figure 1 and Figure 2Positioning in the z-direction can be achieved using the clamping member 120 (for example, by using the limiting arm 121 of the clamping member 120 described in a later embodiment of the present invention to position the lens 200 in the z-direction). This improves the consistency of the position of the lens 200 after loading, thereby ensuring the consistency of the results after adjusting the lens module and improving the imaging clarity and consistency of the lens module.

[0051] In this embodiment of the invention, the clamping member 120 is movably disposed on at least one side of the placement area 111. In some possible interpretations, the clamping member 120 can also be understood as being movable on the base 110. Specifically, in this embodiment of the invention, the direction of movement of the clamping member 120 can be towards the placement area 111. For example, after the lens 200 is placed on the placement area 111, the clamping member 120 can move along the direction towards the placement area 111 to clamp the lens 200.

[0052] It is understood that in this embodiment of the invention, the clamping member 120 can be disposed on one side of the placement area 111, and a fixed block, baffle or plate can be disposed on the other side of the placement area 111 (specifically, the side opposite to the clamping member 120). During the process of the clamping member 120 moving toward the placement area 111, the clamping member 120 applies a clamping force to the lens 200 placed in the placement area 111. At this time, the block, baffle or plate located on the opposite side of the clamping member 120 can apply a reverse force to the lens 200, thereby clamping the lens 200 stably.

[0053] In specific settings, for example, refer to Figure 1 As shown, the clamping member 120 can be specifically disposed on the front side of the placement area 111 (e.g., Figure 1 (as shown in the x-direction) In some possible examples of embodiments of the present invention, the clamping member 120 may also be disposed on the rear side of the placement area 111 (e.g., the side shown in the x-direction). Figure 1 (The negative direction of x is shown on one side).

[0054] Additionally, it is understandable that after the lens module is adjusted, the lens 200 needs to be removed from the placement area 111 (also known as unloading). At this time, the clamping member 120 can move in a direction away from the placement area 111, for example by the operator or by the drive motor, so that the clamping member 120 no longer provides clamping force to the lens 200 (also known as unlocking the lens 200), thus facilitating the unloading of the lens 200.

[0055] Reference Figure 1 and Figure 2As shown in the embodiment of the present invention, the clamping member 120 is provided with a limiting arm 121 at one end facing the placement area 111. The limiting arm 121 is adapted to abut against the lens 200 to limit the degree of freedom of the lens 200 in a preset direction, which is the direction away from the base 110.

[0056] Reference Figure 1 As shown, in some specific examples, a portion of the sidewall or edge of the lens 200 can be placed on and supported by the placement area 111; for example, refer to Figure 1 As shown, the sidewall of the lens 200 may have a supporting protrusion, which can be placed at the edge of the placement area 111 (e.g., at the edge of a perforation or groove), specifically resting on the upper surface of the base 110. In this embodiment of the invention, the limiting arm 121 can specifically abut against the side of the protrusion facing away from the base 110. In this way, the clamping member 120, the limiting arm 121, and the base 110 clamp the lens 200, thereby ensuring that the position of the lens 200 will not move and ensuring precise control of the position of the lens 200.

[0057] When setting up the specific configuration, refer to... Figure 2 As shown, the limiting arm 121 can be formed by first bending upwards from the main body of the clamping member 120, and then bending along the extending direction of the main body of the clamping member 120. Figure 1 The direction shown is illustrated as a specific example; the limiting arm 121 can first move along... Figure 1 The lens 200 is bent in the z-direction and then in the x-direction. It is understood that when the clamping member 120 holds the lens 200, the limiting arm 121 at least blocks the side of the lens 200 facing away from the base 110. As a specific example, the limiting arm 121 can form an interference fit with the side of the protrusion facing away from the base 110. That is, the gap between the side of the limiting arm 121 facing the base 110 and the base 110 can be slightly smaller than the distance between the side of the protrusion facing away from the base 110 and the base 110 (in some examples, this can be understood as the thickness of the protrusion).

[0058] Of course, in some examples, the side of the protrusion facing away from the base 110 can also be set as an inclined slope. In this way, when the limiting arm 121 contacts the inclined surface, the limiting arm 121 can provide a component force in the direction perpendicular to the inclined surface, thereby exerting a component force on the lens 200 towards / facing the base 110, which can more stably limit the lens 200.

[0059] It is understood that in the foregoing embodiments of the present invention, the clamping member 120 is mainly shown as moving in a straight line as a specific example. In some possible examples, the clamping member 120 may also be rotatably disposed on the base 110. For example, a rotating shaft may be provided on the base 110, and the clamping member 120 is rotatably connected to the base 110 through the rotating shaft. When it is necessary to clamp the lens 200, the limiting arm 121 of the clamping member 120 rotates to the placement area 111. When it is necessary to unload the lens module, the limiting arm 121 of the clamping member 120 is rotated away from the placement area 111.

[0060] The clamping assembly 100 provided in this embodiment of the invention provides a clamping member 120 on at least one side of the placement area 111 of the base 110, and a limiting arm 121 at one end of the clamping member 120 facing the placement area 111. Thus, when the lens 200 is placed in the placement area 111 of the base 110, and the clamping member 120 clamps the lens 200, the limiting arm 121 can abut against the object to be clamped (e.g., the lens 200), thereby restricting the movement of the lens 200 in the direction away from the base 110. This prevents the position of the lens 200 from shifting when subjected to external forces. In other words, when adjusting the positions of the lens 200 and the sensor plate, the precision control of the lens 200's position can be ensured, thereby guaranteeing the clarity of the image after adjustment and effectively preventing changes in the image after adjustment.

[0061] Figure 3 This is a schematic diagram of the structure of the clamping component in the clamping assembly provided in an embodiment of the present invention. Figure 4 This is a front view of the clamping component in the clamping assembly provided in this embodiment of the invention.

[0062] Reference Figure 3 and Figure 4 As shown, in an optional example of an embodiment of the present invention, the limiting arm 121 is a wedge-shaped body, the side of the wedge-shaped body facing the base 110 is a first inclined surface 122 that is inclined relative to the surface of the base 110, and the converging end of the wedge-shaped body faces the placement area 111.

[0063] Specifically, in this embodiment of the invention, after the limiting arm 121 is formed, a first inclined surface 122 can be formed by cutting the lower surface of the limiting arm 121. In this embodiment of the invention, the converging end of the wedge faces the placement area 111, that is, the thickness of the end of the limiting arm 121 facing the placement area 111 is smaller, and the thickness of the end of the limiting arm 121 facing away from the placement area 111 is larger; in addition, the inclination direction of the first inclined surface 122 is upward from the end facing away from the placement area 111 to the end close to the placement area 111. In this way, when the clamping member 120 clamps the lens 200, the first inclined surface 122 of the limiting arm 121 abuts against the lens 200; a pressing force on the lens 200 can exist in the direction perpendicular to the first inclined surface 122, thereby stably positioning the lens 200 on the base 110 and preventing the lens 200 from shifting.

[0064] Figure 5 This is a top view schematic diagram of a clamping assembly provided in an embodiment of the present invention. Figure 6 It is along Figure 5 A cross-sectional view of line AA in the middle.

[0065] Reference Figure 5 and Figure 6 As shown, a specific example is given in this embodiment of the invention.

[0066] Reference Figure 6 As shown, the clamping member 120 provides a clamping force F to the lens 200. The clamping force F has a component force F1 in the direction perpendicular to the first inclined plane 122. (Refer to...) Figure 6 As shown, Figure 6 The direction indicated by the dashed line can be along or parallel to the first inclined surface 122. The component force F1 can provide downward pressure on the lens 200 in the vertical direction, thereby pressing and positioning / limiting the lens 200 on the base 110, ensuring the stability of the lens 200's positioning and clamping. In addition, in this embodiment of the invention, by setting the limiting arm 121 as a wedge, the first inclined surface 122 of the wedge contacts the lens 200, thereby clamping the lens 200; in this way, the inclined surface can disperse the clamping force F, making the clamping force acting on the lens 200 dispersed, which can prevent the lens 200 from deforming and improve the clarity and accuracy of the image captured by the lens 200.

[0067] As an optional example of the present invention, the first inclined surface 122 is inclined relative to the surface of the base 110 to form an included angle α, the angle of which is 15°-60°.

[0068] Specifically, in this embodiment of the invention, the surface of the base 110 can be Figure 4The horizontal surface is shown in the figure. Typically, the surface of the base 110 is also horizontal during use. It is understood that in some specific examples of embodiments of the present invention, the angle of inclination of the first inclined surface 122 can be 15°, 30°, 45°, or 60°; as a specific example of an embodiment of the present invention, the angle of inclination of the first inclined surface 122 can be 28.8°.

[0069] It is understandable that when the inclination angle of the first inclined plane 122 is 0° or 90°, the clamping force F (e.g., ...) on the clamping member 120 is... Figure 6 As shown, neither of these components can generate a vertical force component, thus limiting the vertical positioning effect on the lens 200. Specifically, as the tilt angle of the first inclined surface 122 changes within the range of 0°-90°, the downward pressure component force provided by the clamping member 120 on the lens 200 gradually increases and then gradually decreases. Therefore, in this embodiment of the invention, setting the tilt angle of the first inclined surface 122 within the range of 15°-60° ensures that the clamping member 120 can provide sufficient downward pressure component force to the lens 200, thereby stably limiting the lens 200. Furthermore, it disperses the clamping force F, reducing the force applied to the lens 200 in the horizontal direction and preventing deformation of the lens 200.

[0070] In this embodiment of the invention, the angle of inclination of the first inclined surface 122 relative to the surface of the base 110 is set to 15°-60°. This allows the clamping force F to provide more downward component force F1, while the force in the horizontal direction is more dispersed. On the one hand, it can better and more stably clamp the lens 200 on the base 110, avoiding displacement of the lens 200. On the other hand, it can effectively disperse the radial clamping force that directly presses on the lens 200, effectively preventing deformation of the lens 200 and improving the clarity of the image captured by the lens 200.

[0071] As an optional example of an embodiment of the present invention, refer to Figure 1 , Figure 2 and Figure 6 As shown, there are two clamping members 120, which are arranged opposite to each other on both sides of the placement area 111; the two clamping members 120 are adapted to clamp the object to be clamped from both sides of the placement area 111.

[0072] Specifically, in this embodiment of the invention, using Figure 1 The directions shown are illustrated as specific examples. Figure 1The positive x-direction can specifically refer to the front side of the clamping assembly 100, and the negative x-direction can refer to the rear side of the clamping assembly 100. When adjusting the lens module, the operator can operate from the front side of the clamping assembly 100. In this embodiment of the invention, the two clamping members 120 can be arranged along the front-rear direction of the base 110. That is, one clamping member 120 can be arranged on the front side of the placement area 111, and the other clamping member 120 can be arranged on the rear side of the placement area 111.

[0073] Understandably, in some possible examples, the two clamping members 120 may also move in the left-right direction along the base 110. It should be noted here that the left-right direction of the base 110 can specifically be... Figure 1 The positive and negative directions are indicated by the y-direction; for example, the positive y-direction can be the right side of the base 110, and the negative y-direction can be the left side of the base 110. One of the two clamping members 120 can be located on the right side of the placement area 111, and the other clamping member 120 can be located on the left side of the placement area 111.

[0074] In this embodiment of the invention, by providing two clamping members 120 on opposite sides of the placement area 111, the two clamping members 120 can clamp the lens 200 from both sides, ensuring that the clamping force on both sides of the lens 200 is the active clamping force provided by the clamping members 120. This avoids the occurrence of stress concentration in local areas of the lens 200 when clamped, effectively protecting the lens 200 and improving the imaging quality after the lens module is calibrated.

[0075] In an optional example of an embodiment of the present invention, refer to Figure 2 and Figure 5 As shown, the base 110 is provided with a first guide groove 112, which is located on both sides of the placement area 111; at least a portion of the clamping member 120 is movably disposed within the first guide groove 112.

[0076] Specifically, in this embodiment of the invention, the extending direction of the first guide groove 112 is consistent with the moving direction of the clamping member 120. As a specific example, see... Figure 2 As shown, in this embodiment of the invention, the clamping member 120 may be specifically disposed on the front side of the placement area 111 (e.g., Figure 1The clamping member 120 moves along the front-back direction (i.e., along the direction shown by the x-axis) and the rear side; and the clamping member 120 moves along the front-back direction (i.e., along the direction shown by the x-axis); therefore, in this embodiment of the invention, the first guide groove 112 can also extend along the x-direction. Furthermore, it is understood that in this embodiment of the invention, the length of the first guide groove 112 can be greater than the length of the clamping member 120, or the length of the first guide groove 112 can be greater than the length of the portion of the clamping member 120 embedded in the first guide groove 112. This facilitates the movement of the clamping member 120 within the first guide groove 112 along the length direction (also referred to as the extension direction) of the first guide groove 112.

[0077] In specific configurations, in this embodiment of the invention, the first guide groove 112 may be integrally formed with the base 110. Of course, in some examples, the first guide groove 112 may also be obtained by secondary processing of the base 110 after the base 110 has been manufactured.

[0078] It is understood that, in some optional examples of the embodiments of the present invention, the first guide groove 112 may be a groove formed by recessing from the surface of the base 110. In other optional examples of the embodiments of the present invention, the first guide groove 112 may also be formed by providing two opposing blocks on the surface of the base 110, with a certain distance reserved between the two blocks, so that the gap between the two blocks can form the first guide groove 112.

[0079] In this embodiment of the invention, by providing a first guide groove 112 on the base 110 and placing at least a portion of the clamping member 120 within the first guide groove 112, the first guide groove 112 can guide the movement of the clamping member 120, ensuring the stability of the movement of the clamping member 120, thereby ensuring the stability of the clamping force provided by the clamping member 120 to the lens 200, and preventing the lens 200 from deforming due to stress concentration; thus improving the imaging quality after the lens module is calibrated.

[0080] Understandably, referring to Figure 2 As shown, in this embodiment of the invention, there may be two first guide grooves 112, located on opposite sides of the placement area 111. As a specific example, the first guide grooves 112 are spaced apart from the placement area 111. In other words, the first guide groove 112 has a baffle / sidewall extending beyond the placement area 111 on one side. This baffle / sidewall can limit the movement of the clamping member 120, preventing excessive movement of the clamping member 120 towards the placement area 111 and thus avoiding difficulties in the loading operation, thereby improving the convenience of the loading operation.

[0081] Figure 7This is a schematic diagram of another overall structure of the clamp assembly provided in an embodiment of the present invention.

[0082] In an optional example of an embodiment of the present invention, refer to Figure 2 and Figures 5-7 As shown, the clamp assembly 100 also includes a first drive member 140, which is connected to the clamping member 120. The first drive member 140 is used to drive the clamping member 120 to move towards or away from the placement area 111.

[0083] Specifically, in this embodiment of the invention, the first driving member 140 may provide a force to the clamping member 120 facing / or toward the placement area 111 only, for example, referring to Figure 6 As shown, the first driving member 140 can only provide a force F toward the placement area 111 to the clamping member 120; that is, the first driving member 140 only drives the clamping member 120 to clamp the lens 200. At this time, when it is necessary to unload the lens 200, the operator can manually operate and move the clamping member 120, so that the clamping member 120 moves away from the placement area 111, and then remove the lens 200 from the placement area 111, thereby realizing unloading.

[0084] As a specific example, the first driving member 140 can be two magnets with the same poles facing each other. One magnet can be disposed on the side wall of the first guide groove 112 at the end opposite to the placement area 111; the other magnet can be disposed on the clamping member 120. It is understood that there is a repulsive force between the two magnets with the same poles facing each other, so that the clamping member 120 is driven by the repulsive force and clamps the lens 200.

[0085] It is understood that, as an optional example of an embodiment of the present invention, the first driving member 140 may also be two magnets with opposite poles facing each other, one of which is disposed on one of the two clamping members 120; the other of which is disposed on the other clamping member 120. The two magnets move the two clamping members 120 toward each other by mutual attraction, thereby clamping the lens 200.

[0086] As some optional examples of embodiments of the present invention, the first driving member 140 may also be a driving member capable of driving the clamping member 120 to move toward the placement area 111 or to move the clamping member 120 away from the placement area 111. For example, when it is necessary to clamp the lens 200, the first driving member 140 may drive the clamping member 120 to move toward the placement area 111; when it is necessary to unload the lens 200 (i.e., to remove / take away the lens 200 from the placement area 111), the first driving member 140 may drive the clamping member 120 to move away from the placement area 111.

[0087] In a specific configuration, the first driving component 140 can be a linear motor, a piston cylinder, or a pneumatic cylinder, etc.; the output shaft of the linear motor, piston cylinder, or pneumatic cylinder can be connected to the end of the clamping component 120 facing away from the placement area 111, thereby driving the clamping component 120 to move.

[0088] In this embodiment of the invention, the clamping member 120 is driven by the first driving member 140 to move toward the placement area 111, thereby clamping the lens 200. This ensures that the clamping member 120 always has a stable clamping force on the lens 200, and avoids displacement or offset of the clamping member 120 during the adjustment process.

[0089] In a specific example of an embodiment of the present invention, refer to Figure 2 , Figure 5 and Figure 6 As shown, the first driving member 140 is a spring. The first end of the spring abuts against the side of the clamping member 120 facing away from the placement area 111, and the second end of the spring is connected to the groove wall of the first guide groove 112. The spring is used to drive the clamping member 120 to move toward the placement area 111.

[0090] Specifically, in this embodiment of the invention, the spring can be a helical spring. It is understood that the helical spring is disposed between the groove wall of the first guide groove 112 and the clamping member 120. The helical spring can be in a compressed state, thus providing the clamping member 120 with an elastic restoring force toward / pointing towards the placement area 111, for example... Figure 6 The force F in the middle; thus, the clamping member 120 always has a stable clamping force on the lens 200.

[0091] In this embodiment of the invention, the clamping member 120 has a first limiting post 123 on the side facing away from the placement area 111, and the first limiting post 123 passes through the spring coil.

[0092] It is understood that, in this embodiment of the invention, the first limiting post 123 may be integrally formed with the clamping member 120. In some examples, the first limiting post 123 may also be connected to the clamping member 120 to form an integral structure by welding or threaded connection. In specific settings, the first limiting post 123 may be a cylindrical structure, or in some examples, the first limiting post 123 may be a square post, a prismatic post, or other structures. In this embodiment of the invention, the specific shape of the first limiting post 123 is not limited.

[0093] It is also understood that, in this embodiment of the invention, the first limiting post 123 can be inserted inside the spring coil, so that the compression direction of the spring is along the axial direction of the first limiting post 123, thereby ensuring that the spring can provide a stable elastic force to the clamping member 120, ensuring the stability of the force direction of the clamping member 120 on the lens 200, avoiding the occurrence of concentrated stress on the lens 200 that could cause lens 200 deformation, and improving the imaging quality after the lens module is calibrated.

[0094] As an optional example of an embodiment of the present invention, refer to Figure 2 , Figure 6 and Figure 7 As shown, the groove wall is provided with a second limiting post 141, which is inserted through the second end.

[0095] Specifically, in this embodiment of the invention, the groove wall specifically refers to the groove wall of the first guide groove 112 on the side facing away from the placement area 111. The second limiting post 141 specifically can be a boss protruding from the inner wall of the first guide groove 112. Specifically, the second limiting post 141 can be integrally formed with the groove wall, for example, by cutting the base 110 with a milling cutter or a lathe to form the second limiting post 141. In some possible examples, the second limiting post 141 can also be set on the groove wall by welding or threaded connection.

[0096] To illustrate with a specific example, in this embodiment of the invention, the second limiting post 141 can be a screw, bolt, or threaded rod. In a specific configuration, a through hole can be provided in the groove wall, for example, a through hole along the extending direction of the first guide groove 112; the screw, bolt, or threaded rod is threaded into the through hole, and at least a portion of the screw, bolt, or threaded rod protrudes from the inner side of the first guide groove 112. This facilitates the installation and connection of the second limiting post 141, facilitates the installation of the spring and clamping member 120, and improves the installation and assembly efficiency of the clamping assembly.

[0097] As an optional example of an embodiment of the present invention, the spring stiffness coefficient can be selected as a helical spring of 250 N / m-350 N / m. In some specific examples, when the clamping member 120 clamps the lens 200, the spring compression can be 5 mm-8 mm. In some specific examples, the spring stiffness coefficient can be 300 N / m, and when the clamping member 120 clamps the lens 200, the spring compression can be 6.2 mm.

[0098] It should be noted that the numerical values ​​and ranges involved in the embodiments of the present invention are approximate values. Due to the influence of the manufacturing process, there may be a certain range of errors, which can be considered negligible by those skilled in the art.

[0099] It is understood that in this embodiment of the invention, since two opposing clamping members 120 are provided on both sides of the placement area 111, when the spring applies elastic force to the clamping members 120, the clamping members 120 on both sides will apply clamping force to the lens 200 from both sides. The first inclined surface 122 of the limiting arm 121 disperses the elastic force of the spring into a vertically downward limiting pressure on the lens 200. This ensures that the limiting arm 121 has sufficient downward limiting pressure on the lens 200, ensuring that the position of the lens 200 will not move during the adjustment process, thereby improving the imaging quality after the lens 200 module is adjusted.

[0100] Figure 8 It is along Figure 5 Another cross-sectional view of line AA in the middle.

[0101] As an optional example of an embodiment of the present invention, refer to Figure 8 As shown, the spring can also be disposed at one end of the clamping member 120 facing / towards the placement area 111. Specifically, the spring abuts against the sidewall of the clamping member 120 and the first guide groove 112 facing / towards the placement area 111. It can be understood that, at this time, after the spring is compressed, the elastic force provided by the spring is... Figure 6 The spring force F in the spring is in the opposite direction. That is to say, the spring is mainly used to drive the clamping part 120 to move away from the placement area 111. This makes it easy to unlock the clamping part 120 from the lens 200 and to facilitate the unloading of the lens 200.

[0102] It is understood that, in this embodiment of the invention, a through hole can be provided in the groove wall of the first guide groove 112 on the side opposite to the placement area 111. A supporting member (such as a screw, bolt, or threaded rod) is screwed into the through hole. The supporting member applies a supporting force to the clamping member 120, thereby causing the clamping member 120 to overcome the spring force and move towards the placement area 111, thus clamping the lens 200. When it is necessary to unload the lens 200, the supporting member can be loosened or removed, thereby causing the spring to push the clamping member 120 to move away from the placement area 111.

[0103] In some alternative examples of embodiments of the present invention, the first driving member 140 may also have a sleeve with internal threads, and the first limiting post 123 may be provided with external threads, and the first limiting post 123 is threadedly connected to the sleeve. In a specific configuration, a through hole may be provided on the groove wall of the first guide groove 112 on the side opposite to the placement area 111, and part of the sleeve may be disposed in the through hole and fixed axially with the through hole (i.e., a limiting structure may be provided on the inner wall of the through hole to restrict the freedom of the sleeve along the axial direction of the through hole); in the circumferential direction, the sleeve is rotatably connected to the through hole; in this way, by rotating the sleeve, the sleeve can drive the clamping member 120 to move toward or away from the placement area 111 via the thread.

[0104] Reference Figure 1 , Figure 2 and Figure 7 As shown, in an optional example of an embodiment of the present invention, the clamp assembly 100 further includes a second drive member 150, which is movably disposed on the base 110 and at least a portion of the second drive member 150 is connected to the clamping member 120; the second drive member 150 is adapted to drive the clamping member 120 to move away from the placement area 111.

[0105] It is understood that in some examples of embodiments of the present invention, the second driving member 150 may be of the same or similar type as the first driving member 140. For example, in some examples, the second driving member 150 may also be a linear motor, cylinder, or piston cylinder as described in the foregoing embodiments of the present invention. In embodiments of the present invention, the output end of the second driving member 150 (e.g., the output shaft of a linear motor, the movable shaft of a cylinder) may be connected to the clamping member 120 and push the clamping member 120 to move away from the placement area 111.

[0106] In some specific examples, when the first driving member 140 is a spring, and the spring is located on the side of the clamping member 120 facing away from the placement area 111, it can be understood that the main function of the spring is to push the clamping member 120 towards the placement area 111. At this time, the second driving member 150 can provide a force to overcome the deformation of the spring, driving the clamping member 120 to move away from the placement area 111. In this way, after the lens 200 module has been adjusted, it is convenient to unload the lens 200 module.

[0107] In an optional example of an embodiment of the present invention, refer to Figures 3-5 and Figure 7 As shown, the clamping member 120 is provided with a force-receiving part 124, which is located at one end of the clamping member 120 facing away from the limiting arm 121; the second driving member 150 is movably connected to the side of the force-receiving part 124 facing the placement area 111.

[0108] Specifically, in this embodiment of the invention, the force-receiving part 124 may be a protrusion protruding from the surface of the clamping member 120, or the force-receiving part 124 may be a protruding post. In some possible examples of this embodiment of the invention, the force-receiving part 124 may also be a groove formed on the surface of the clamping member 120, with the sidewall of the groove facing away from the placement area 111 configured as the force-receiving part 124. That is, the sidewall of the groove facing away from the placement area 111 is connected to the second driving member 150 and receives the drive of the second driving member 150.

[0109] In this embodiment of the invention, by providing a force-receiving part 124 on the clamping member 120 and setting the force-receiving part 124 at one end of the clamping member 120 away from the limiting arm 121, it is convenient for the second driving member 150 to drive the clamping member 120 through the force-receiving part 124, and to facilitate the connection between the second driving member 150 and the clamping member 120.

[0110] Figure 9 This is a top view of the clamping component in the clamping assembly provided in this embodiment of the invention.

[0111] As an optional example of an embodiment of the present invention, refer to Figure 3 , Figure 5 , Figure 7 and Figure 9 As shown, the force-receiving part 124 has a second inclined surface 125 on the side facing the second driving member 150, and the second inclined surface 125 is inclined relative to the direction of movement of the clamping member 120.

[0112] Specifically, refer to Figure 7 As shown, in this embodiment of the invention, the direction of movement of the clamping member 120 can be along... Figure 7 The direction indicated by the x-axis. In some specific examples, the direction indicated by the x-axis can also be the operator's operating direction, usually referred to as the front of the base 110. It should be noted that the inclination of the second inclined surface 125 relative to the direction of movement of the clamping member 120 means that the inclination direction of the second inclined surface 125 is neither parallel nor perpendicular to the direction indicated by the x-axis. That is, the second inclined surface 125 and the direction indicated by the x-axis can form at least an acute angle, or at least an obtuse angle.

[0113] Alternatively, in another understanding of the embodiments of the present invention, referring to Figure 9 As shown, it can also be understood that the inclination direction of the second inclined surface 125 is inclined relative to the clamping direction of the clamping member 120.

[0114] Figure 10 This is a schematic diagram of the overall structure of the second driving component in the clamp assembly provided in the embodiment of the present invention.

[0115] In this embodiment of the invention, reference is made to Figure 10 As shown, the second driving member 150 has a relief part 151 on the side facing the force-bearing part 124, and the relief part 151 is adapted to avoid the force-bearing part 124.

[0116] Specifically, refer to Figure 10As shown, in this embodiment of the invention, the second driving member 150 can specifically be a sheet metal part, and the clearance portion 151 can specifically be a groove provided on the side of the second driving member 150 facing the force-receiving portion 124. In this way, when the clamping member 120 provides clamping force to the lens 200, the force-receiving portion 124 can be located within the clearance portion 151, which can ensure that the clamping member 120 moves normally towards the placement area 111 and provides clamping force to the lens 200.

[0117] It is understood that, in this embodiment of the invention, the sidewall of the clearance portion 151 may be chamfered, rounded, or rollers may be provided at the edge of the sidewall of the clearance portion 151. This facilitates the force-bearing portion 124 to exit from the clearance portion 151, thereby unlocking the lens 200 and facilitating the unloading operation of the lens 200 module.

[0118] Figure 11 This is another structural schematic diagram of the clamp assembly provided in an embodiment of the present invention. Figure 12 This is another top view of the clamp assembly provided in an embodiment of the present invention.

[0119] Reference Figure 5 and Figure 7 As shown, in the embodiment of the present invention, the clamp assembly 100 is in a first position when the second drive member 150 is in the first position (e.g., Figure 5 and Figure 7 The position shown is such that when the clamping member 120 clamps the lens 200, at least a portion of the force-bearing part 124 can sink into / embed into the clearance part 151, thereby ensuring that the clamping member 120 can move from both sides of the placement area 111 toward each other and clamp the lens 200.

[0120] Reference Figure 11 and Figure 12 As shown, after the lens module has been calibrated, it needs to be removed from placement area 111 to allow for the loading of the next lens 200 that requires calibration. For specific operation, refer to... Figure 11 and Figure 12 As shown, specifically along Figure 11 or Figure 12 The second drive member 150 is moved in the x-direction, causing it to move from the first position to the second position (e.g., ...). Figure 11 and Figure 12 (As shown in the diagram), the side wall or edge of the clearance portion 151 of the second driving member 150 interacts with the second inclined plane 125. That is, when the second driving member 150 moves in the x-direction, the force exerted on the force-bearing portion 124 in the x-direction can be decomposed into forces parallel to the second inclined plane 125 and forces perpendicular to the second inclined plane 125. Among them, the component force perpendicular to the second inclined plane 125 can be decomposed into forces along... Figure 12The thrust shown in the y-direction pushes the clamping member 120 to move away from the placement area 111, causing the limiting arm 121 to move away from the placement area 111 and share the force with the lens 200, thus facilitating the unloading of the lens module.

[0121] Reference Figure 11 and Figure 12 As shown, when the force-bearing part 124 completely retracts from the avoidance part 151, the clamping relationship between the clamping member 120 and the lens 200 is completely released, that is, the limiting arm 121 is completely moved away from the side of the lens 200 facing away from the base 110, which facilitates the unloading of the lens module.

[0122] As a specific example of an embodiment of the present invention, refer to Figure 11 and Figure 12 As shown, after the force-receiving part 124 completely retracts from the avoidance part 151, the force-receiving part 124 abuts against the side of the second driving member 150 facing the force-receiving part 124, and the second driving member 150 keeps the clamping member 120 in the unlocked state through the force-receiving part 124. At this time, the compression of the spring can be 9mm-11mm. In some specific examples, the compression of the spring can be 9mm, 10mm, or 11mm, etc. As a specific example of an embodiment of the present invention, the compression of the spring can be 10.2mm.

[0123] As a specific example of an embodiment of the present invention, refer to Figure 9 As shown, the second inclined surface 125 is inclined at an angle of 45°-75° relative to the direction of movement of the clamping member 120.

[0124] Specifically, with Figure 9 The direction shown is illustrated as an example; the direction of the second inclined surface can be... Figure 9 The direction indicated by the dashed line, the direction of movement of the clamping member 120 can be represented by the extended sidewall or edge line of the clamping member 120. That is... Figure 9 The angle β between the dashed line and the edge of the clamping member 120 is the angle at which the second inclined surface 125 is tilted relative to the direction of movement of the clamping member 120. In some specific examples, the angle β can be 45°, 60°, or 75°, etc. As a specific example of an embodiment of the present invention, the angle β can specifically be 62.2°.

[0125] In an optional example of an embodiment of the present invention, refer to Figure 10 As shown, the clearance portion 151 is inclined toward the side wall of the second inclined surface 125, and the inclination angle of the side wall matches the inclination angle of the second inclined surface 125.

[0126] Specifically, in this embodiment of the invention, the side wall of the avoidance portion 151 that interacts with the second inclined surface 125 can be inclined. For example, refer to... Figure 11As shown, the avoidance part 151 has a side wall located in the negative x-axis direction that interacts with the second inclined surface 125. In this embodiment of the invention, this inclined surface can be set at an angle.

[0127] It is understood that in this embodiment of the invention, the tilt angle of the side wall of the avoidance part 151 can be adapted to the tilt angle of the second inclined surface 125. That is, the tilt direction of the side wall of the avoidance part 151 is consistent with the tilt direction of the second inclined surface 125. This facilitates the side wall of the avoidance part 151 to act on the second inclined surface 125, and facilitates the movement of the clamping member 120, thereby enabling the unlocking and unloading operation of the lens module.

[0128] Continue to refer to Figure 11 and Figure 12 As shown, in an optional embodiment of the present invention, the base 110 is further provided with a protrusion 113, which is located at the opening of the first guide groove 112; Refer to Figure 2 As shown, the first sidewall 114 of the protrusion 113 abuts against the first inner wall of the second drive member 150 and guides the movement direction of the second drive member 150; thereby ensuring that the second drive member 150 is slidably disposed on the base 110 through the cooperation of the first sidewall 114 and the first inner wall.

[0129] Specifically, refer to Figure 11 and Figure 12 As shown, in this embodiment of the invention, the protrusion 113 can specifically be disposed at the edge of the opening of the first guide groove 112. The protrusion 113 can be integrally formed with the base 110. In some examples, the protrusion 113 can also be formed on the surface of the base 110 by welding. In some optional examples, the protrusion 113 can be fixed to the base 110 by connecting components such as screws, bolts, or threaded rods.

[0130] Reference Figure 7 , Figure 10 and Figure 12 As shown, in an optional example of an embodiment of the present invention, the second driving member 150 is provided with a limiting protrusion 152 on the side facing away from the placement area 111, and the limiting protrusion 152 is located on both sides of the protrusion 113; the limiting protrusion 152 is adapted to contact the second sidewall 115 of the protrusion 113 to limit the displacement of the second driving member 150.

[0131] Specifically, refer to Figure 12 As shown, in this embodiment of the invention, along the second driving member 150 Figure 12When the clamping member 120 is driven to the maximum displacement in the direction indicated by the x-axis, the force-bearing part 124 abuts against the side wall of the second driving member 150; in this embodiment of the invention, the limiting protrusion 152 protrudes from the side wall of the second driving member 150 that abuts against the side facing away from the placement area 111 as a reference surface.

[0132] During the movement of the second drive member 150, for example... Figure 12 As an example, along the second drive element 150 Figure 12 During the movement in the direction shown by the x-axis, the limiting protrusion 152 will interfere with the second sidewall 115 of the protrusion 113, thereby limiting the displacement distance of the second driving member 150, preventing the second driving member 150 from falling off, and ensuring the effectiveness of the second driving member 150 in driving the clamping member 120.

[0133] As a specific example of an embodiment of the present invention, refer to Figure 2 As shown, a second guide groove 116 may be provided on the protrusion 113, wherein the first sidewall 114 may be the inner wall of the second guide groove 116, and the extension direction of the second guide groove 116 may be orthogonal to the extension direction of the first guide groove 112. For example, in some examples, the extension direction of the second guide groove 116 may be perpendicular to the extension direction of the first guide groove 112. It should be noted that in this embodiment of the invention, the extension directions of the first guide groove 112 and the second guide groove 116 may deviate to some extent due to machining tolerances or process errors; this error or deviation can be ignored. That is to say, in this embodiment of the invention, the extension directions of the first guide groove 112 and the second guide groove 116 may be approximately perpendicular.

[0134] Specifically, with Figure 12 As a specific example, the extension direction of the first guide groove 112 can be considered as... Figure 12 The direction shown by the y-axis, the extension direction of the second guide groove 116 can be considered as... Figure 12 The direction indicated by the x-axis. Specifically, the second driving member 150 can be disposed within the second guide groove 116 and move along the second guide groove 116.

[0135] In a specific configuration, the second driving member 150 can be positioned on the side of the clamping member 120 facing away from the base 110. That is, the second driving member 150 can be pressed against the clamping member 120, and the direction of movement of the second driving member 150 is orthogonal to the direction of movement of the clamping member 120.

[0136] In an optional example of an embodiment of the present invention, refer to Figure 1 and Figure 2As shown, the clamp assembly 100 also includes a limiting cover plate 130, which covers the side of the second drive member 150 facing away from the base 110.

[0137] Specifically, in this embodiment of the invention, the limiting cover 130 may be made of the same material as the base 110. Alternatively, the limiting cover 130 may be made of sheet metal. In a specific configuration, the limiting cover 130 may be detachably connected to the base 110, for example, by means of connecting components such as screws, bolts, or threaded rods.

[0138] In a specific configuration, the limiting cover 130 can be placed on the protrusion 113, for example, by connecting it to the protrusion 113 with bolts, screws, or threaded rods, thereby limiting the second driving member 150.

[0139] In this embodiment of the invention, by providing a protrusion 113 on the surface of the base 110 and setting the protrusion 113 at the opening of the first guide groove 112, the protrusion 113 can extend / extend the first guide groove 112, that is, increase the depth of the first guide groove 112, which facilitates the installation and storage of the clamping member 120.

[0140] In addition, a second guide groove 116 orthogonal to the first guide groove 112 is provided on the protrusion 113, and the second driving member 150 is disposed in the second guide groove 116. In this way, the second guide groove 116 can guide the movement of the second driving member 150, ensuring the stability of the movement of the second driving member 150, thereby ensuring the stability of the second driving member 150 driving the clamping member 120.

[0141] It is understood that in this embodiment of the invention, the two clamping members 120 are disposed opposite to each other on both sides of the placement area 111; in this embodiment of the invention, referring to... Figure 10 As shown, the second driving member 150 can be specifically configured as an O-type or annular structure. The second driving member 150 has a through hole in the middle, which allows the lens 200 or lens module to pass through, facilitating the loading of the lens 200 and the unloading of the lens module. Furthermore, by configuring the second driving member 150 as an O-type or annular, avoidance parts 151 can be provided on both sides of the second driving member 150. This means that both sides of the second driving member 150 can drive or avoid the clamping member 120, ensuring that both clamping members 120 can be unlocked simultaneously / synchronously. This avoids the situation where a single clamping member 120 exerts force on the lens 200, causing excessive stress on the lens 200, effectively protecting the lens 200 from deformation and improving the imaging quality of the calibrated lens module.

[0142] In some other possible examples of embodiments of the present invention, the second driving member 150 may also be configured as C-shaped. It is understood that when the second driving member 150 is configured as C-shaped, the two end sidewalls of the C-shaped second driving member 150 interact with the two clamping members 120, and its specific function is the same as or similar to that when the second driving member 150 is annular or O-shaped, as can be found in the detailed description of the foregoing embodiments of the present invention.

[0143] Additionally, in another example of an embodiment of the present invention, reference is made to... Figure 5 As shown, along the second drive member 150 Figure 5 When moving in the y-direction, the limiting protrusion 152 located on the other side of the protrusion 113 can interfere with the second sidewall 115 of the protrusion 113, thereby limiting the displacement distance of the second driving member 150, preventing the second driving member 150 from falling out of the second guide groove 116, and ensuring the effectiveness of the second driving member 150 in driving the clamping member 120.

[0144] It is understood that, in this embodiment of the invention, to facilitate the installation of the second driving member 150, the second guide groove 116 has an opening on the side facing away from the base 110, and the second driving member 150 is installed into the second guide groove 116 through the opening. To prevent the second driving member 150 from falling off from the opening, in this embodiment of the invention, the limiting cover plate 130 can specifically cover the opening of the second guide groove 116. That is, the limiting cover plate 130 covers the side of the second driving member 150 facing away from the base 110.

[0145] Figure 13 This is another structural schematic diagram of the clamp assembly provided in the embodiment of the present invention.

[0146] In an optional example of an embodiment of the present invention, refer to Figure 13 As shown, the clamp assembly 100 also includes a third drive member 160, the output end of which is connected to the second drive member 150, and the third drive member 160 is adapted to drive the second drive member 150 to move.

[0147] Specifically, in this embodiment of the invention, the third driving component 160 can be a linear motor, a cylinder, a piston cylinder, or other driving component. In specific configurations, the third driving component 160 can be mounted on the base 110. In some optional examples, the third driving component 160 can also be mounted on other components of the lens 200 adjustment device. In this embodiment of the invention, the specific location of the third driving component 160 is not limited.

[0149] Reference Figure 14 and Figure 15 As shown, in an optional example of an embodiment of the present invention, the base 110 is further provided with a positioning part 117, which is provided on at least two sides of the placement area 111; the positioning part 117 is adapted to cooperate with the positioning structure on the object to be clamped in order to position the object to be clamped.

[0150] Specifically, in this embodiment of the invention, the positioning part 117 can be two, three, or four, etc. In this way, at least two positioning parts 117 can form at least two positioning points, thereby determining the positioning on a straight line and preventing the lens 200 from rotating.

[0151] In this embodiment of the invention, by providing a positioning part 117 on the base 110 and disposing the positioning part 117 on at least both sides of the placement area 111, the lens 200 can be positioned by the positioning part 117 when loading the lens 200 into the placement area 111. This effectively improves the accuracy of the fixed position of the lens 200 after loading, resulting in high consistency of the loading position and high positioning accuracy. This ensures the imaging quality of the lens module after calibration.

[0152] It is understood that, in the embodiments of the present invention, reference is made to... Figure 14 As shown, the positioning part 117 can be a positioning post disposed on the base 110; wherein, the positioning post can be a cylinder or a prism. In this case, the positioning structure on the lens 200 can be a positioning hole, and the positioning post passes through the positioning hole to realize the positioning of the loading position of the lens 200.

[0153] In other examples of embodiments of the present invention, the positioning part 117 may also be a positioning hole provided on the base 110; in specific configurations, the positioning part 117 may be either a through hole or a blind hole. It is understood that in some examples, at least one of the two positioning parts 117 may be a through hole and the other may be a blind hole. This provides a foolproof positioning mechanism for the lens 200, ensuring the consistency of the lens 200 loading position and the accuracy of the lens 200 positioning position.

[0154] In some alternative examples of embodiments of the present invention, refer to Figure 1 and Figure 2 As shown, a gripping part 118 is also provided at one end of the base 110.

[0155] It is understood that in this embodiment of the invention, the gripping part 118 may be disposed at the end of the base 110 facing the operator, which may also be referred to as the front end of the base 110. As a specific example, see... Figure 1 and Figure 2As shown, the gripping part 118 can be provided at one end of the base 110 along the positive direction of the x-axis.

[0156] Specifically, the grip 118 can be a handle or a pull ring. When it is necessary to unload the adjusted lens module, the operator only needs to pull the entire base 110 through the grip 118. In this way, the clamping component can be pulled out from the adjustment position, so that the loading of the lens 200, the unloading of the lens module and the adjustment of the lens module are in different positions and will not affect each other, which makes it convenient to load the lens 200 and unload the adjusted lens module.

Figure 17 This is a schematic diagram of another overall structure of the lens clamping device provided in an embodiment of the present invention. Figure 18 This is an exploded structural diagram of the lens clamping device provided in an embodiment of the present invention. Figure 19 This is a schematic diagram of the loading or unloading scenario of the lens clamping device provided in the embodiment of the present invention.

[0158] Reference Figures 16-19 As shown, this embodiment of the invention also provides a lens clamping device 10, including a base 300 and a clamping assembly 100 of any of the foregoing embodiments of the invention, wherein the clamping assembly 100 is movably disposed on the base 300.

[0159] Specifically, in this embodiment of the invention, the base 300 may be made of materials such as stainless steel, aluminum alloy or cast iron. In some optional examples, the base 300 may also be made of the same material as the base 110.

[0160] In an optional example of an embodiment of the present invention, refer to Figure 18 and Figure 19 As shown, the base 300 is provided with a slide rail 301 and a sliding block 302, and the sliding block 302 is slidably disposed on the slide rail 301; the sliding block 302 is adapted to be connected to the base 110 of the clamp assembly 100.

[0161] It is understandable that slide rail 301 can also be called guide rail, and sliding block 302 is slidably mounted on slide rail 301. (Refer to...) Figure 18 and Figure 19 As shown, there can be two slide rails 301, arranged parallel to each other. This ensures the stability of the sliding block 302 as it slides on the slide rails 301 by the slidable connection between the two rails and the sliding block 302. Furthermore, it also ensures the stability of the sliding block 302's support for the clamp assembly 100, guaranteeing the consistency and positioning accuracy of the lens 200 after loading.

[0162] As an optional example of an embodiment of the present invention, refer to Figures 16-19 As shown, the rear end of the base 300 is provided with a positioning component 303, which is used to position the base 110.

[0163] Specifically, in this embodiment of the invention, after the base 110 is positioned by the positioning member 303, the position of the base 110 remains unchanged during the adjustment process, thereby ensuring the accuracy and consistency of the position of the lens 200 positioned on the base 110, and ensuring the accuracy and consistency of the adjustment of the lens 200 module.

[0164] In some specific examples, the positioning element 303 can be a magnet, and the base 110 can be made of cast iron; in this way, the magnet can attract the base 110, thereby positioning the base 110. In other specific examples, the positioning element 303 can also be a snap-fit, and the base 110 can be snapped into and positioned with the positioning element 303. It is understood that in some optional examples of the embodiments of the present invention, the positioning element 303 can also be an electromagnet. During the adjustment of the lens 200 module, the electromagnet is energized to attract the base 110, thereby positioning the base 110.

[0165] As an optional example of an embodiment of the present invention, a fourth driving member (not shown in the figure) is also provided on the base 300. The fourth driving member is adapted to drive the base 110 to move. Specifically, in this embodiment of the present invention, the fourth driving member can also be a cylinder, a linear motor, or a piston cylinder, etc., and there is no limitation on this in this embodiment of the present invention. The fourth driving member can be specifically disposed on the base 300. In some optional examples of this embodiment of the present invention, the fourth driving member can also be disposed on other components, as long as the output end of the fourth driving member is connected to the base 110 and can drive the base 110 to move.

[0168] It is understood that in this embodiment of the invention, the sensor board clamp 20 is used to hold the sensor board. During specific calibration, the sensor board clamp 20 holds the sensor board on the clamping post and brings it close to the lens 200 on the clamp assembly 100. The calibration is determined to be complete by observing the test image formed by the lens 200.
