[0048] The image of the lens under test is acquired through the calibration module 200, and the centering operation device 500 enables the quick-change module 300 to quickly change the lens under test according to the acquired image. The calibration module 200 and the teleconverter 410 module 400 work together. Each time the lens under test 320 is changed, it is only necessary to acquire the image of the lens under test 320 according to the calibration module 200, and adjust the working distance of the teleconverter 410, the module bracket 420 and the collimator 430 to complete the quick change operation of the lens under test, thereby reducing the change time and cost of the equipment.

[0049] It should be noted that the light source emitted by the calibration module 200 converges to the lens 320 to be tested, so that the calibration light source and the working light source can be distinguished. The calibration light source provided by the calibration module 200 is used to enable the centering operation device 500 to obtain the precise standard parameters of the equipment. First, a first distance between the calibration module 200 and the teleconverter 410 is determined. The first test distance is simulated as a second test distance by the teleconverter 410 module 400, wherein the second test distance is in the range of 50 mm to 5000 mm. The lens clamping device 330 is used to move the lens 320 to be tested, so as to obtain a calibration image. The centering operation device performs a preliminary centering operation on the lens 320 to be tested according to the calibration image, moves the X-axis and Y-axis of the lens clamping device 330 to adjust the center of the lens 320 to be tested, and then moves the Z-axis of the lens clamping device 330 to scan out a first center clarity curve and multiple first surrounding clarity curves of the lens 320 to be tested.

[0050] In some embodiments of the present invention, the lens 320 to be tested is provided with a photosensitive chip 340 , which is disposed at the bottom of the lens 320 to be tested, and the connection position between the photosensitive chip 340 and the lens 320 to be tested is coated with UV glue.

[0051] It should be noted that after the teleconverter 410 module 400 simulates the first test distance as the second test distance, the lens to be tested and the photosensitive chip 340 are loaded through the loading carrier, the lens to be tested is moved above the photosensitive chip 340, the photosensitive chip 340 is lit, the light of the lens to be tested 320 is recorded through the photosensitive chip 340, and after the light signal is converted into an image signal, the real-time image of the lens to be tested 320 is transmitted to the centering operation device 500.

[0052] In some embodiments of the present invention, the first bracket 440 and the second bracket 450 are both provided with a sliding track 460, the first bracket 440 is provided with a first connecting member 441, one end of the first connecting member 441 is connected to the parallel light tube 430, and the other end of the first connecting member 441 is provided with a plurality of rotating wheels 442 and placed in the sliding track 460, and the parallel light tube 430 and the sliding track 460 form a sliding connection through the plurality of rotating wheels 442 of the first connecting member 441. It should be noted that by arranging sliding rails 460 on the first bracket 440 and the second bracket 450, relative sliding can be performed between the first bracket 440 and the second bracket 450 and the bracket body 100, thereby achieving adjustment and positioning at different positions. In addition, the first sliding connector is respectively placed in the sliding rails 460 of the first bracket 440 and the second bracket 450 and connected to multiple teleconverters 410, so that the light emitted by the parallel light tube 430 can be adjusted in position through the rotating wheel 442, while ensuring the stable connection between the teleconverter 410 and the first bracket 440 and the second bracket 450.

[0053] In some embodiments of the present invention, a rotation adjustment mechanism for adjusting the module bracket 420 to rotate left and right is provided inside the bracket body 100. The rotation adjustment mechanism is provided with a guide rail 470, a second connecting member 480 and a third connecting member 490. One end of the second connecting member 480 is connected to the first bracket 440, and the other end of the second connecting member 480 is placed in the guide rail 470 for adjusting the rotation angle of the module bracket 420. The third connecting member 490 is respectively connected to the second bracket 450 and the rotation adjustment mechanism.

[0054] It should be noted that, in this embodiment, by setting the guide rail 470, the second connecting member 480 and the third connecting member 490, the first bracket 440 can be adjusted to rotate left and right relative to the second bracket 450 inside the bracket body 100. By adjusting the left and right rotation angles, different viewing angles and directions can be quickly switched to meet different shooting requirements of the lens 320 to be tested. Furthermore, the guide rail 470, the second connecting member 480 and the third connecting member 490 can achieve precise control and positioning of the rotation angle of the module bracket 420, so that the calibration module 200 can emit a precise light source to align the lens 320 to be tested, providing a clear and stable image. In addition, by setting the second connecting member 480 and the third connecting member 490, the rotation adjustment mechanism can be stably installed inside the bracket body 100, thereby further improving the safety and stability of the module bracket 420 during use.

[0055] The calibration module 200 is provided with a light source board 210, an image test card 220 and an angle adjustment mechanism 230. The image test card 220 is fixed to the top of the bracket body 100. The angle adjustment mechanism 230 is respectively connected to the light source board 210 and the graphic test card. The image test card 220 is provided with a through hole, which is aligned with the position of the light source emitted by the light source board 210.

[0056] It should be noted that by aligning the through hole on the image test card 220 with the position of the light source emitted by the light source board 210, it is ensured that the light source in the calibration module 200 is correctly irradiated onto the image test card 220, thereby ensuring the accuracy and consistency of the calibration result. In addition, the angle adjustment mechanism 230 enables the operator to adjust the angle between the light source board 210 and the image test card 220, adjust the irradiation angle according to the changeover standard, and ensure that the light source board 210 and the image test card 220 can maintain a stable position and angle, thereby reducing errors and deviations in the rapid changeover process, thereby improving the accuracy and reliability of the calibration.

[0057] Reference Figure 5 , Figure 5 A flowchart of a method for rapid camera module changeover based on an embodiment of the present invention is provided. The method for rapid camera module changeover based on an embodiment of the present invention includes but is not limited to the following steps:

[0058] Step S11, obtaining real-time image information of the lens to be tested and calibration midpoint information of the calibration device, and calculating the midpoint deviation value according to the real-time image information and the calibration midpoint information;

[0059] Step S12, moving the X-axis and the Y-axis of the lens clamping device to a first position according to the calibration midpoint information, wherein the midpoint of the lens to be tested moved to the first position is aligned with the calibration device;

[0060] Step S13, moving the Z axis of the lens clamping device to obtain a first center clarity curve and a plurality of first surrounding clarity curves of the lens to be tested, and calculating a first angle deviation value of the lens to be tested according to the first center clarity curve and the plurality of first surrounding clarity curves;

[0061] Step S14, moving the X-axis, Y-axis and Z-axis of the lens clamping device at the first position according to the preset path planning algorithm and the first angle deviation value, moving the lens clamping device to the second position, adjusting the Z-axis of the lens clamping device at the second position, obtaining a second center clarity curve and a plurality of second surrounding clarity curves, and calculating a second angle deviation value according to the second center clarity curve and the plurality of second surrounding clarity curves;

[0062] Step S15, the midpoint deviation value and the second angle deviation value are compared according to a preset movement range, Z-axis movement information of the lens clamping device is obtained, and the collimator and the teleconverter are changed according to the Z-axis movement information.

[0063] It should be noted that the lens clamping device is controlled by the centering operating device to obtain the first angle deviation value and the second angle deviation value of the lens to be tested in different positions, and the second angle deviation value and the key deviation value are compared according to the preset moving range to obtain the movement information of the Z axis. The centering operating device completes the rapid mold changing operation through the lens clamping device according to the movement information of the Z axis, thereby improving the detection efficiency and detection accuracy, further enhancing the centering detection quality, and improving the compatibility and changing speed of the rapid mold changing equipment.

[0064] In addition, in one embodiment, referring to Figure 6 ,exist Figure 5 Before step S11 of the illustrated embodiment, the following steps are also included but not limited to:

[0067] S23, loading the photosensitive chip and the lens to be tested moved above the photosensitive chip by a loading carrier, so that the camera changing module can obtain real-time image information.

[0068] It should be noted that after the lens clamping device moves the lens to be tested to above the photosensitive chip according to the second distance, the Z-axis of the mobile lens clamping device compensates for the shrinkage of the photosensitive chip, and the glue applied to the photosensitive chip is solidified by aiming a high-intensity ultraviolet lamp at the glue. This allows the lens clamping device to accurately move the lens to be tested to above the photosensitive chip, thereby improving the operating efficiency and production efficiency of the mold changing module and further improving the mold changing speed.

[0069] In addition, in one embodiment, referring to Figure 7 ,exist Figure 1 Step S15 of the illustrated embodiment further includes but is not limited to the following steps:

[0070] S31, when the second angle deviation value is not within the range of the midpoint moving range, moving the X-axis and the Y-axis of the lens clamping device until the second angle deviation value is within the range of the preset range;

[0071] S32, when the second angle deviation value is within the range of the midpoint moving range, obtaining the current position of the lens to be tested and the current position of the photosensitive chip of the camera module according to the midpoint deviation value and the second surrounding clarity curve;

[0072] S33, the lens clamping device moves the Z axis according to the current position of the lens to be tested and the current position of the photosensitive chip.

[0073] It should be noted that when the second angle deviation value is not within the range of the midpoint movement range, the X-axis and Y-axis of the lens clamping device are moved until the second angle deviation value is within the range of the preset range, thereby ensuring that the lens to be tested can be correctly placed above the photosensitive chip, reducing errors and waste caused by position deviation, and obtaining the current position of the lens to be tested and the photosensitive chip of the camera module according to the key deviation value and the second and fourth peripheral clarity curves, thereby quickly and accurately obtaining the current position of the lens to be tested and the current position of the photosensitive chip, automatically adjusting the Z-axis of the lens clamping device, and improving the centering accuracy and the efficiency of the rapid changeover operation.

[0074] In this embodiment, the specific operation process of the camera module-based device is as follows:

[0075] Apply glue to the outside of the photosensitive chip. The glue width is 1mm and the glue height is 0.5mm. The preset distance between the lens to be tested and the photosensitive chip is 7mm, the preset distance between the lens to be tested and the teleconverter is 200mm, the preset distance between the collimator and the lens to be tested is 100-300mm, and the distance between the calibration module and the teleconverter is 300mm.
