Description

Technical Field

[0001] The present invention relates to the technical field of lens adjustment devices, and more particularly, to a lens eccentricity adjustment device. Background Art

[0002] With the continuous development of optical design software, it has become common to design an excellent optical lens. However, the corresponding optical processing technology and alignment technology still need to be continuously developed. Optical processing will cause an eccentricity error in a single lens in an optical lens group. However, the realization of the structural functions of the entire optical system is based on lens design, that is, it is necessary to ensure that the optical axes of all components in the optical system coincide with the ideal axis. In the actual design and processing process, processing errors and assembly errors will still be introduced, resulting in the non-existence of this ideal axis (optical axis) in actual production and manufacturing. Therefore, the optical lens will inevitably have an eccentricity error, and this rotational asymmetry will also cause aberrations such as coma, astigmatism, and distortion in the optical system.

[0003] In the process of manufacturing a multi-group lens, it is necessary to adjust the lenses between two adjacent groups to be as close as possible to the same optical axis, thereby reducing the eccentricity and reducing the aberration phenomenon. Summary of the Invention

Two adjustment blocks and an adjustment wheel are provided on the test surface. The two adjustment blocks and the adjustment wheel are arranged along the circumference of the test hole. The adjustment blocks and the adjustment wheel are respectively located on both sides of the test hole and are used to limit the first group of the multi-group lens. The adjustment wheel can rotate around an axis to drive the first group to rotate, and its rotation axis is perpendicular to the test surface. The adjustment wheel can move radially along the test hole to approach and depart from the test hole;

[0008] An adjustment device, provided on the working platform. The adjustment device is provided with a clamping claw for clamping the second group of the multi-group lens. The clamping claw can drive the second group to move relative to the first group to adjust the eccentricity between the second group and the first group;

[0013] Secondly, the adjustment wheel can drive the first group to rotate continuously, which is beneficial for the test device to obtain the eccentricity of multiple groups of lenses, thereby improving the adjustment effect and efficiency;

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0052] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating relative importance or indicating the quantity of technical features. In the description of the present invention, "a plurality of" means two or more unless otherwise specifically defined. The following describes the specific implementation of the present invention in more detail with reference to specific embodiments:

[0053] As Figures 1 to 3 shown, a lens eccentricity adjustment device provided by an embodiment of the present invention can be understood to be used for adjusting the eccentricity of a multi-group lens 10; specifically, the multi-group lens 10 in this embodiment includes a first group 101 and a second group 102 stacked and connected to the first group 101. A first lens is provided in the first group 101, and a second lens is provided in the second group 102. Among them, in the production process, in order to pursue as small a phase difference as possible, it is necessary to adjust the first lens and the second lens to the same optical axis; for this reason, this embodiment provides a lens eccentricity adjustment device for reducing the eccentricity of the multi-group lens 10; the following is described by specific implementation:

[0054] The lens eccentricity adjustment device includes: a working platform 1, a testing platform 2, an adjustment device 3, a testing device 4, and a calibration device 5;

[0055] The working platform 1 is used to be fixed in the production site, and is used to support the testing platform 2, the adjustment device 3, the testing device 4, and the calibration device 5, and to raise the height of the working station for adjusting multiple groups of lenses 10, so as to facilitate the operation of production personnel;

[0056] The testing platform 2 is arranged on the working platform 1. A testing surface 21 for placing multiple groups of lenses 10 and testing holes 22 opened on the testing surface 21 are provided on the testing platform 2. Two adjustment blocks 23 and an adjustment wheel 24 are provided on the testing surface 21. The two adjustment blocks 23 and the adjustment wheel 24 are arranged along the circumferential direction of the testing holes 22. The adjustment blocks 23 and the adjustment wheel 24 are respectively located on both sides of the testing holes 22 and are used to limit the first group 101 of the multiple groups of lenses 10. The adjustment wheel 24 can rotate around an axis to drive the first group 101 to rotate and its rotation axis is perpendicular to the testing surface 21. The adjustment wheel 24 can move along the radial direction of the testing holes 22 to approach and depart from the testing holes 22;

[0057] It can be understood that the testing platform 2 is used to carry and fix multiple groups of lenses 10;

[0058] Specifically, the test platform 2 is disposed on the working platform 1. There is a test surface 21 on the test platform 2. In order to enable the multi-group lens 10 to be placed flat on the test surface 21, the test surface 21 is preferably parallel to the horizontal plane. Among them, the multi-group lens 10 covers the test hole 22, so that light can pass through the multi-group lens 10 and the test hole 22 in sequence, facilitating the test device 4 to obtain the test result. The adjustment block 23 and the adjustment wheel 24 are used to jointly clamp the multi-group lens 10. Among them, the first group 101 in the multi-group lens 10 is located below the second group 102, that is, the first group 101 is close to the test platform 2, so that the adjustment block 23 and the adjustment wheel 24 can clamp the first group 101. In order to enable the adjustment block 23 and the adjustment wheel 24 to firmly clamp the first group 101, the number of adjustment blocks 23 is at least two and they are respectively arranged on both sides of the test hole 22 with the adjustment wheel 24. That is, when the multi-group lens 10 is placed on the test hole 22, the adjustment block 23 and the adjustment wheel 24 are respectively located on both sides of the multi-group lens 10. The adjustment wheel 24 can move radially along the test hole 22 from one side of the multi-group lens 10, and at the same time move the multi-group lens 10 towards the adjustment block 23 until it abuts against the adjustment block 23. The two adjustment blocks 23 and one adjustment wheel 24 respectively abut against three points on the circumference of the multi-group lens 10 from different sides, so that the multi-group lens 10 is firmly fixed. In order to enable the adjustment block 23 and the adjustment wheel 24 to adapt to the first group 101 of different sizes, the distance between the adjustment wheel 24 and the adjustment block 23 can also be adjusted. Specifically, it is only necessary to move the adjustment wheel 24 radially along the test hole 22.

[0059] The adjustment device 3 is disposed on the working platform 1. The adjustment device 3 is provided with a clamping claw 31 for clamping the second group 102 in the multi-group lens 10. The clamping claw 31 can drive the second group 102 to move relative to the first group 101 to adjust the eccentricity between the second group 102 and the first group 101.

[0060] It can be understood that the clamping claw 31 is used to clamp the second group 102 in the multi-group lens 10, so that the second group 102 can move relative to the first group 101. In this way, the eccentricity between the second group 102 and the first group 101 can be adjusted.

[0061] The test device 4 is disposed between the test platform 2 and the working platform 1 and is electrically connected to the adjustment device 3. The test device 4 is provided with a test head 41 corresponding to the test hole 22.

[0062] It can be understood that the testing device 4 is used to obtain an image passing through the multi-group lens 10, and analyze the eccentricity of the multi-group lens 10 with the image; specifically, the eccentricity between the first group 101 and the second group 102 in the multi-group lens 10 will be reflected in the captured image, and the testing device 4 analyzes the eccentricity error of the multi-group lens 10 by obtaining the image, and then outputs control information to the adjusting device 3, so that the clamping claw 31 of the adjusting device 3 drives the second group 102 to move relative to the first group 101, and adjusts the eccentricity of the second group 102 and the first group 101;

[0063] The calibration device 5 is disposed on the working platform 1 . The calibration device 5 is provided with a calibration head 51 located on a side of the testing platform 2 away from the testing head 41 . The calibration head 51 corresponds to the testing hole 22 .

[0064] It can be understood that the calibration head 51 is provided with a backlight module, and the light emitted by the backlight module passes through the multi-group lens 10 and enters the test head 41 of the test device 4, so that the test device 4 can obtain the calibration pattern of the calibration head 51 through the multi-group lens 10. The test device 4 analyzes the degree of eccentricity between the first group 101 and the second group 102 in the multi-group lens 10 by analyzing the degree of distortion of the calibration pattern.

[0065] The working principle of the lens eccentricity adjustment device provided in this embodiment is as follows:

[0066] The multi-group lens 10 is placed on the test hole 22, where the first lens of the first group 101 and the second lens of the second group 102 are arranged in a stacked manner with the upper and lower layers. At this time, the first group 101 of the multi-group lens 10 has not yet abutted against the adjustment block 23 and the adjustment wheel 24. The production personnel start the adjustment wheel 24 to move the adjustment wheel 24 along the radial direction of the test hole 22 until it abuts against the outer edge of the multi-group lens 10. Then the adjustment wheel 24 drives the multi-group lens 10 to move towards the adjustment block 23 until it abuts against the adjustment block 23. At this time, the two adjustment blocks 23 and one adjustment wheel 24 clamp the multi-group lens 10. Since the first group 101 is located below the second group 102, the adjustment block 23 and the adjustment wheel 24 clamp the first group 101. The production personnel start the adjustment wheel 24 to rotate around the axis. At this time, the adjustment wheel 24 drives the multi-group lens 10 to rotate (the part of the adjustment block 23 in contact with the multi-group lens 10 is provided with pulleys or a relatively smooth surface so that the multi-group lens 10 can rotate relative to the adjustment block 23). At the same time, the test device 4 and the calibration device 5 are started, so that the test device 4 obtains the calibration pattern, and then analyzes the eccentricity between the first group 101 and the second group 102. Then the clamping claw 31 of the adjustment device 3 is started to clamp the second group 102, so that the second group 102 moves relative to the first group 101, and then adjusts the eccentricity between the two. In order to obtain better adjustment effects and improve the adjustment efficiency, when the clamping claw 31 adjusts the second group 102, the first group 101 keeps rotating, the test device 4 continuously obtains the calibration pattern, and then continuously adjusts the relative positions of the second group 102 and the first group 101 according to the calibration pattern.

[0067] By adopting the above technical solutions:

[0068] First of all, the adjustment block 23 and the adjustment wheel 24 can clamp the first group 101 in the multi-group lens 10, and the clamping claw 31 can clamp and move the second group 102 in the multi-group lens 10. This enables the first group 101 and the second group 102 to move relative to each other, and then adjust the relative positions, thereby adjusting the eccentricity between the two, reducing the phenomenon of phase difference caused by eccentricity in the multi-group lens 10;

[0069] Secondly, the adjustment wheel 24 can drive the first group 101 to rotate continuously, which is conducive to the test device 4 obtaining the eccentricity of the multi-group lens 10, and then improving the adjustment effect and adjustment efficiency;

[0070] Finally, the adjustment wheel 24 can move along the radial direction of the test hole 22. In this way, the distance between the adjustment wheel 24 and the adjustment block 23 can be adjusted, and it can be applied to multi-group lenses 10 of different sizes.

[0071] In one embodiment, a first guiding groove 25 is formed along the radial direction of the testing hole 22 on the testing surface 21. The adjusting block 23 is correspondingly slidably disposed in the first guiding groove 25, and the adjusting block 23 can be locked at any position in the first guiding groove 25 to adjust the distance from the testing hole 22.

[0072] It can be understood that the adjusting block 23 and the adjusting wheel 24 jointly clamp the first group 101. In order to enable the adjusting block 23 and the adjusting wheel 24 to adapt to multi-group lenses 10 of different sizes, the adjusting block 23 is designed to be slidable to adjust the distance from the adjusting wheel 24. Specifically, the first guiding groove 25 is formed along the radial direction of the testing hole 22, and the adjusting block 23 is slidably disposed in the first guiding groove 25, so that the adjusting block 23 can move along the radial direction of the testing hole 22. The radial distance between the adjusting block 23 and the testing hole 22 is changed according to the radial dimension of the multi-group lens 10, so that after the multi-group lens 10 is clamped by the adjusting block 23 and the adjusting wheel 24, it can be substantially coaxial with the testing hole 22, which is beneficial for the testing device 4 to obtain the calibration pattern.

[0073] By adopting the above technical solution, the adjustability of the adjusting block 23 in the radial direction enables the adjusting block 23 and the adjusting wheel 24 to adapt to the sizes of multi-group lenses 10 of different sizes, and at the same time improves the coaxial degree between the multi-group lens 10 and the testing hole 22.

[0074] In one embodiment, a second guiding groove 26 is formed along the radial direction of the testing hole 22 corresponding to the adjusting wheel 24 on the testing surface 21. The adjusting wheel 24 is correspondingly slidably disposed in the second guiding groove 26. Two first guiding grooves 25 and one first guiding groove 25 are evenly distributed along the circumferential direction of the testing hole 22.

[0075] It can be understood that the number of the first guiding grooves 25 corresponds to two of the adjusting blocks 23, and the number of the second guiding grooves 26 corresponds to one of the adjusting wheels 24. The two first guiding grooves 25 and one second guiding groove 26 are sequentially distributed along the circumferential direction of the testing hole 22. Specifically, the central angle between two adjacent ones of the two first guiding grooves 25 and one second guiding groove 26 is 120°, so that the two adjusting blocks 23 and one adjusting wheel 24 can evenly abut against three points evenly distributed on the circumference of the first group 101 in the multi-group lens 10, improving the stability of the clamping and rotation of the first group 101.

[0076] By adopting the above technical solution, the stability of the first group 101 during clamping and rotation is improved.

[0077] In one embodiment, please refer to Figure 3 and Figure 4 , the adjusting device 3 includes a Y-axis moving module 32, an X-axis moving module 33, a Z-axis moving module 34 and a clamping driving module 35;

[0078] The Y-axis moving module 32 is disposed on the working platform 1, and the X-axis moving module 33 is slidably disposed on the Y-axis moving module 32 and can move along the Y-axis direction under the driving of the Y-axis moving module 32;

[0079] The Z-axis moving module 34 is slidably disposed on the X-axis moving module 33 and can move along the X-axis direction under the driving of the X-axis moving module 33;

[0080] The clamping driving module 35 is slidably disposed on the Z-axis moving module 34 and can move along the Z-axis direction under the driving of the Z-axis moving module 34. The clamping driving module 35 is used to drive the clamping claws 31 to clamp the multiple groups of lenses 10.

[0081] The X-axis direction is perpendicular to the Y-axis direction and parallel to the test surface 21 , and the Z-axis direction is perpendicular to the test surface 21 .

[0082] It can be understood that when the lens eccentricity adjustment device is in use, its test surface 21 is parallel to the horizontal plane, so that when the multi-group lens 10 is placed on the test surface 21, its optical axis is perpendicular to the horizontal plane; specifically, the Y-axis moving module 32, the X-axis moving module 33, the Z-axis moving module 34 and the clamping drive module 35 are sequentially connected by transmission. From the above embodiment, it can be seen that through transmission, the X-axis moving module 33 can drive the clamping drive module 35 to move along the X-axis direction, the Y-axis moving module 32 can drive the clamping drive module 35 to move along the Y-axis direction, and the Z-axis moving module 34 can drive the clamping drive module 35 to move along the Z-axis direction, so that the clamping drive module 35 is moved close to the multi-group lens 10, so that the clamping claw 31 can clamp the multi-group lens 10, and at the same time, after clamping the multi-group lens 10, the clamping claw 31 can move the position of the second group 102 relative to the first group 101 according to the eccentricity information of the first group 101 and the second group 102 fed back by the test device 4, thereby adjusting the eccentricity of the two.

[0083] By adopting the above technical solution, it is convenient to adjust the position of the clamping claw 31 of the adjustment device 3 relative to the multiple groups of lenses 10, which is beneficial for the clamping operation of the clamping claw 31.

[0084] In one embodiment, the Y-axis movement module 32 includes a first Y-axis rail 321, a second Y-axis rail 322, a Y-axis drive member 323, a Y-axis slider 324, and a Y-axis fine adjustment member 325. The first Y-axis rail 321 is arranged on the working platform 1 along the Y-axis direction. The second Y-axis rail 322 is slidably arranged on the first Y-axis rail 321 and extends along the Y-axis direction. The Y-axis drive member 323 is connected to the second Y-axis rail 322 and is used to drive the second Y-axis rail 322 to move along the Y-axis direction. The Y-axis slider 324 is slidably arranged on the second Y-axis rail 322. The Y-axis fine adjustment member 325 is connected to the Y-axis slider 324 and is used to adjust the position of the Y-axis slider 324 on the second Y-axis rail 322.

[0085] It can be understood that the Y-axis movement module 32 is used to adjust the position of the clamping drive module 35 in the Y-axis direction. To improve the efficiency and accuracy of the adjustment, the adjustment method is divided into coarse adjustment and fine adjustment. Specifically, the coarse adjustment is completed by the second Y-axis rail 322 and the Y-axis drive member 323. The second Y-axis rail 322 is slidably arranged on the first Y-axis rail 321, and the Y-axis drive member 323 is used to drive the second Y-axis rail 322 to move along the Y-axis direction. The Y-axis drive member 323 can be selected as a motor. Such an adjustment method has a low accuracy and can only adjust the clamping drive module 35 to a rough position. The fine adjustment is completed by the Y-axis slider 324 and the Y-axis fine adjustment member 325. The Y-axis slider 324 is slidably arranged on the second Y-axis rail 322. Since the second Y-axis rail 322 extends along the Y-axis direction, the Y-axis fine adjustment member 325 can drive the Y-axis slider 324 to move along the Y-axis direction. The Y-axis fine adjustment member 325 can be selected as a lead screw. Such an adjustment method has a high accuracy and can accurately adjust the position of the clamping drive module 35. Finally, the clamping drive module 35 drives the clamping jaw 31 to move.

[0086] By adopting the above technical solution, both the efficiency and accuracy of adjusting the clamping drive module 35 in the Y-axis direction are taken into account. Furthermore, the relative positions of the second group 102 and the first group 101 in the Y-axis direction can be adjusted with higher accuracy according to the eccentricity information of the first group 101 and the second group 102 feedback by the testing device 4.

[0087] In one embodiment, the X-axis movement module 33 includes an X-axis rail 331, an X-axis slider 332, and an X-axis fine adjustment member 333. The X-axis rail 331 is arranged on the Y-axis slider 324 along the X-axis direction. The X-axis slider 332 is slidably arranged on the X-axis rail 331. The X-axis fine adjustment member 333 is connected to the X-axis slider 332 and is used to drive the X-axis slider 332 to move along the X-axis direction.

[0088] It can be understood that the X-axis moving module 33 is used to adjust the position of the clamping driving module 35 in the X-axis direction. To improve the adjustment accuracy, the adjustment method is set to micro-adjustment. Specifically, the micro-adjustment is completed by the X-axis slider 332 and the X-axis fine-tuning member 333. The X-axis slider 332 is slidably disposed on the X-axis rail 331. Since the X-axis rail 331 extends in the X-axis direction, the X-axis fine-tuning member 333 can drive the X-axis slider 332 to move in the X-axis direction. The X-axis fine-tuning member 333 can be selected as a lead screw. Such an adjustment method has a high accuracy and can accurately adjust the position of the clamping driving module 35.

[0089] By adopting the above technical solution, the accuracy of adjusting the clamping driving module 35 in the X-axis direction is improved. Furthermore, the relative positions of the second group 102 and the first group 101 in the X-axis direction can be adjusted with higher accuracy according to the eccentricity information of the first group 101 and the second group 102 feedback by the testing device 4.

[0090] In one embodiment, the Z-axis moving module 34 includes a first Z-axis rail 341, a second Z-axis rail 342, a Z-axis driving member 343, a Z-axis slider 344, and a Z-axis fine-tuning member 345. The first Z-axis rail 341 is arranged on the X-axis slider 332 in the Z-axis direction. The second Z-axis rail 342 is slidably disposed on the first Z-axis rail 341. The Z-axis driving member 343 is connected to the second Z-axis rail 342 and is used to drive the second Z-axis rail 342 to move in the Z-axis direction. The Z-axis slider 344 is slidably disposed on the second Z-axis rail 342. The Z-axis fine-tuning member 345 is connected to the Z-axis slider 344 and is used to adjust the position of the Z-axis slider 344 on the second Z-axis rail 342.

[0091] It can be understood that the Z-axis moving module 34 is used to adjust the position of the clamping driving module 35 in the Z-axis direction. To improve the adjustment efficiency and accuracy, the adjustment method is divided into coarse adjustment and micro-adjustment. Specifically, the coarse adjustment is completed by the second Z-axis rail 342 and the Z-axis driving member 343. The second Z-axis rail 342 is slidably disposed on the first Z-axis rail 341, and the Z-axis driving member 343 is used to drive the second Z-axis rail 342 to move in the Z-axis direction. The Z-axis driving member 343 can be selected as a motor. Such an adjustment method has a low accuracy and can only adjust the clamping driving module 35 to a rough position. The micro-adjustment is completed by the Z-axis slider 344 and the Z-axis fine-tuning member 345. The Z-axis slider 344 is slidably disposed on the second Z-axis rail 342. Since the second Z-axis rail 342 extends in the Z-axis direction, the Z-axis fine-tuning member 345 can drive the Z-axis slider 344 to move in the Z-axis direction. The Z-axis fine-tuning member 345 can be selected as a lead screw. Such an adjustment method has a high accuracy and can accurately adjust the position of the clamping driving module 35.

[0092] By adopting the above technical solution, the efficiency and accuracy of adjusting the clamping drive module 35 in the Z-axis direction are taken into account at the same time. Furthermore, the relative positions of the second group 102 and the first group 101 in the Z-axis direction can be adjusted with high precision according to the eccentricity information of the first group 101 and the second group 102 fed back by the test device 4.

[0093] In one embodiment, the clamping drive module 35 includes a clamping track 351 and a clamping drive member 352. The clamping track 351 is arranged on the Z-axis slider 344 along the X-axis direction. The number of clamping claws 31 is two, and the two clamping claws 31 are symmetrically slidably arranged in the clamping track 351. The clamping drive member 352 is connected to the clamping claws 31 and is used to drive the clamping claws 31 to move along the X-axis direction.

[0094] It can be understood that the length direction of the clamping track 351 is parallel to the X-axis direction, and the clamping claws 31 are slidably arranged on the clamping track 351. In this way, the clamping drive member 352 can drive the clamping claws 31 to move along the X-axis direction. Specifically, the two clamping claws 31 are opened relatively and clamped on the circular side surface of the second group 102 of the multi-group lens 10. The clamping claws 31 move along the X-axis direction, so as to drive the second group 102 to move in the X-axis direction to adjust the relative position with the first group 101, and further adjust the eccentricity with the first group 101.

[0095] By adopting the above technical solution, it is convenient for the clamping claws 31 to perform the clamping action.

[0096] In one embodiment, the lens eccentricity adjustment device further includes a curing device 6. The curing device 6 is arranged on the working platform 1, and the curing device 6 is provided with a curing head 61 for curing the multi-group lens 10.

[0097] It can be understood that the first group 101 and the second group 102 of the multi-group lens 10 are fixed by gluing, and a glue that can be cured under ultraviolet light is coated between the first group 101 and the second group 102. Therefore, after the eccentricity adjustment of the first group 101 and the second group 102 is completed, the glue can be cured by the ultraviolet light emitted by the curing head 61 to realize the encapsulation of the multi-group lens 10.

[0098] By adopting the above technical solution, it is beneficial to improve the production efficiency of the multi-group lens 10.

[0099] In one embodiment, please refer to Figure 5, the curing device 6 includes a curing frame 62, a curing rotating frame 63 and a curing rotation driving member 64. The curing frame 62 is erected on the working platform 1. The curing rotating frame 63 can rotate around an axis on the curing frame 62. The rotation axis of the curing rotating frame 63 is parallel to the Z-axis direction. The curing rotation driving member 64 is used to drive the curing rotating frame 63 to rotate around the axis. The curing head 61 is formed on the curing rotating frame 63.

[0100] It can be understood that the curing head 61 has a working state and a stop state. Among them, the curing frame 62 supports the curing rotating frame 63 and the curing rotation driving member 64. The curing rotating frame 63 is rotatably arranged on the curing frame 62. The curing head 61 is formed at the movable end of the curing rotating frame 63. In this way, the curing rotation driving member 64 drives the curing rotating frame 63 to rotate, and the curing rotating frame 63 drives the curing head 61 to rotate, so that the curing head 61 can approach and move away from the multi-group lens 10. Therefore, after the eccentricity of the multi-group lens 10 is adjusted, the curing head 61 approaches the multi-group lens 10 to cure the glue inside it.

[0101] By adopting the above technical solution, the curing head 61 approaches and moves away from the multi-group lens 10 in a rotating manner, which is beneficial to improving production efficiency.

[0102] In one embodiment, please refer to Figure 6 , the calibration device 5 includes a calibration frame 52, a calibration track 53, a calibration slider 54 and a calibration driving member 55. The calibration frame 52 is erected on the working platform 1. The calibration track 53 is arranged on the calibration frame 52 along the Z-axis direction. The calibration slider 54 is slidably arranged on the calibration track 53. The calibration driving member 55 is used to drive the calibration slider 54 to move along the Z-axis direction. The calibration head 51 is formed on the calibration slider 54.

[0103] It can be understood that when adjusting the eccentricity of different multi-group lenses 10, due to the differences in their optical axes and focal points, it is necessary to change the distance between the calibration head 51 and the test head 41 so that the test device 4 can accurately obtain the calibration pattern. Therefore, the calibration device 5 is set to be adjustable in distance from the test device 4.

[0104] By adopting the above technical solution, it is beneficial to adjust the calibration device 5 to obtain more accurate test information.

[0105] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
