[0038] The following introduces the technical solutions provided by the embodiments of this application with reference to the accompanying drawings.

[0039] Refer to Figure 1 As shown, this application provides an optical lens testing device 100. The optical lens testing device 100 includes a machine platform 110, a test light source 120, a lens fixing base 130 and an imaging module 140. The optical lens testing device 100 can test the optical performance of an optical lens.

[0040] The test light source 120 is disposed on the machine platform 110, and the test light source 120 is movable relative to the machine platform 110. The test light source 120 is used to emit a test light beam. The lens fixing base 130 is disposed on the machine platform 110, and the lens fixing base 130 is movable relative to the machine platform 110. The lens fixing base 130 is used to fix an optical lens, and when the optical lens is fixed to the lens fixing base 130, the optical lens can receive the test light beam. The imaging module 140 is disposed on the machine platform 110, and the imaging module 140 is movable relative to the machine platform 110. The imaging module 140 is used to capture the image formed by the optical lens.

[0041] For the above optical lens testing device 100, the optical lens can be fixed to the lens fixing base 130, and after the optical lens receives the test light beam and forms an image, the imaging module 140 can capture the image formed by the optical lens to perform a performance test on the optical lens. In the optical lens testing device 100 provided in the present application, since the test light source 120, the lens fixing base 130, and the imaging module 140 are all movable relative to the machine platform 110, by adjusting the relative positions among the test light source 120, the lens fixing base 130, and the imaging module 140, it can be ensured that the optical lens, the test light source 120, and the imaging module 140 are kept on the same optical axis, improving the reliability of the performance test of the optical lens. Moreover, by adjusting the relative position and angular relationship between the test light source 120 and the lens fixing base 130, the performance of the optical lens under different light intensity, angle, and distance conditions can be simulated.

[0042] To improve the reliability of the performance test of the optical lens, in one embodiment, referring to Figure 1 and Figure 2 as shown, the optical lens testing device 100 further includes an alignment module 150. The alignment module 150 is disposed on the machine platform 110, and the alignment module 150 can emit a collimated light beam towards the test light source 120, the lens fixing base 130, and the imaging module 140. In this way, the positions of the test light source 120, the lens fixing base 130, and the imaging module 140 can be marked by the collimated light beam, and the position information of the test light source 120, the lens fixing base 130, and the imaging module 140 is fed back to the operator or the central control module. The operator or the central control module makes an adaptive adjustment to the positions of the test light source 120, the lens fixing base 130, and the imaging module 140 to ensure that the optical lens, the test light source 120, and the imaging module 140 are kept on the same optical axis, improving the reliability of the performance test of the optical lens. The relative position relationship between the test light source 120 and the lens fixing base 130 can also be adjusted to simulate the performance of the optical lens under different light intensity and distance conditions. Among them, exemplarily, the collimated light beam emitted by the alignment module 150 is a laser. Since the straightness of the laser is good, the accuracy of the position indication of the test light source 120, the lens fixing base 130, and the imaging module 140 can be improved.

[0043] Specifically, referring to Figure 1 as shown in Figure 2 , the alignment module 150 includes a bracket 151, an adjustment module 152, a collimator 153, and at least three light emitters 154. The bracket 151 is disposed on the machine table 110 by means of welding, screwing, etc. The collimator 153 is movably disposed on the bracket 151 through the adjustment module 152. The collimator 153 can emit a collimated beam toward the test light source 120, the lens holder 130, and the imaging module 140. Since the positions of the test light source 120, the lens holder 130, and the imaging module 140 are different, when the collimator 153 emits a collimated beam toward the test light source 120, the lens holder 130, and the imaging module 140, it is necessary to pre-adjust the position of the collimator 153 through the adjustment module 152 so that the collimated beam emitted by the collimator 153 can be projected onto any one of the test light source 120, the lens holder 130, and the imaging module 140. Exemplarily, as shown in Figure 1 , the adjustment module 152 can adjust the position of the collimator 153 in the X, Y, and Z directions shown to move the collimator 153 to a position where a collimated beam can be projected onto the test light source 120, the lens holder 130, or the imaging module 140. Another example is that the adjustment module 152 can also drive the collimator 153 to rotate around Figure 1 the X, Y, and Z directions shown to calibrate the collimated beam emitted by the collimator 153.

[0044] Among them, the collimator 153 can emit collimated light beams towards the test light source 120, the lens fixing base 130, and the imaging module 140 to show the positions of the test light source 120, the lens fixing base 130, and the imaging module 140, facilitating the operator or the central control module to adaptively adjust the positions of the test light source 120, the lens fixing base 130, and the imaging module 140, ensuring that the optical lens, the test light source 120, and the imaging module 140 are on the same optical axis, improving the reliability of the performance test of the optical lens, and also adjusting the relative positional relationship between the test light source 120 and the lens fixing base 130 to simulate the test performance of the optical lens under different light intensity and distance conditions. Moreover, a plurality of light emitters 154 are movably arranged on the bracket 151, and the plurality of light emitters 154 are spaced apart along the circumferential direction of the collimator 153 on the outside of the collimator 153, and the plurality of light emitters 154 can emit parallel light beams towards the test light source 120, the lens fixing base 130, and the molding module. Exemplarily, since the parallel light beams emitted by the plurality of light emitters 154 can define a plane, such as when the parallel light beams emitted by the plurality of light emitters 154 are projected onto the test light source 120, the lens fixing base 130, or the imaging module 140, if the plane formed by the multiple parallel light beams does not deform and the collimated light beam is just in the middle position of the multiple parallel light beams, it indicates that the test light source 120, the lens fixing base 130, or the imaging module 140 has not undergone angular deflection; another example is that when the parallel light beams emitted by the plurality of light emitters 154 are projected onto the test light source 120, the lens fixing base 130, or the imaging module 140, if the plane formed by the multiple parallel light beams deforms and the collimated light beam deviates from the middle position of the multiple parallel light beams, it indicates that the test light source 120, the lens fixing base 130, or the imaging module 140 has undergone angular deflection. Thus, according to the cooperation of the multiple parallel light beams emitted by the plurality of light emitters 154 and the collimated light beam emitted by the collimator 153, the angular deflection amount of the test light source 120, the lens fixing base 130, or the imaging module 140 can be indicated to simulate the test performance of the optical lens under different light intensity and angle conditions.

[0045] It should be noted that the number of the light emitters 154 can be three, four, or other numbers, and only the number of the light emitters 154 needs to be at least three so that the multiple parallel light beams emitted by the plurality of light emitters 154 can define a plane. The specific number of the light emitters 154 is not limited in this application.

[0046] In one embodiment, refer to Figure 1 And Figure 3As shown in the figure, the test light source 120 includes a first fine-tuning module 121, a first deflection module 122, and a light source generator 123. The first fine-tuning module 121 and the first deflection module 122 are both disposed on the machine table 110. The light source generator 123 is drivingly connected to the first fine-tuning module 121 and the first deflection module 122. The light source generator 123 is used to emit a test beam. The first fine-tuning module 121 can drive the light source generator 123 to perform multi-axis movement. For example, the first fine-tuning module 121 can drive the light source generator 123 to move along Figure 1 the X and Y directions shown in the figure to adjust the relative position relationship between the light source generator 123, the lens fixing base 130, and the imaging module 140. The first deflection module 122 can drive the light source generator 123 to perform multi-axis deflection. For example, the first deflection module 122 can drive the light source generator 123 to rotate around Figure 1 the X and Y directions shown in the figure to adjust the relative angular relationship between the light source generator 123 and the lens fixing base 130.

[0047] For the above optical lens testing device 100, through the cooperation of the first fine-tuning module 121 and the first deflection module 122, on the one hand, it can adjust the relative positions among the test light source 120, the lens fixing base 130, and the imaging module 140, and can ensure that the optical lens, the test light source 120, and the imaging module 140 are on the same optical axis, improving the reliability of the performance test of the optical lens. On the other hand, it can adjust the relative position and angular relationship between the test light source 120 and the lens fixing base 130 to simulate the test performance of the optical lens under different light intensity, angle, and distance conditions.

[0048] In one embodiment, referring to Figure 1 and Figure 4 shown in the figure, the lens fixing base 130 includes a second fine-tuning module 131, a second deflection module 132, and an adsorption module 133. The second fine-tuning module 131 and the second deflection module 132 are both disposed on the machine table 110. The adsorption module 133 is drivingly connected to the second fine-tuning module 131 and the second deflection module 132. The adsorption module 133 is used for adsorbing and fixing the optical lens to achieve automatic positioning and loading of the optical lens, improving the fixing efficiency of the optical lens. The second fine-tuning module 131 can drive the adsorption module 133 to perform multi-axis movement. For example, the second fine-tuning module 131 can drive the adsorption module 133 to move along Figure 1 the X, Y, and Z directions shown in the figure to adjust the relative position relationship between the adsorption module 133, the test light source 120, and the imaging module 140. The second deflection module 132 can drive the adsorption module 133 to perform multi-axis deflection. For example, the second deflection module 132 can drive the adsorption module 133 to rotate around Figure 1 the X, Y, and Z directions shown in the figure to adjust the relative angular relationship between the adsorption module 133 and the test light source 120.

[0049] The above optical lens testing device 100, through the cooperation of the second fine-tuning module 131 and the second deflection module 132, on the one hand, can adjust the relative positions among the test light source 120, the lens fixing base 130 and the imaging module 140, ensuring that the optical lens, the test light source 120 and the imaging module 140 are on the same optical axis, improving the reliability of the performance test of the optical lens. On the other hand, it can adjust the relative position and angular relationship between the test light source 120 and the lens fixing base 130 to simulate the test performance of the optical lens under different light intensity, angle and distance conditions.

[0050] In one embodiment, referring to Figure 1 and Figure 5 as shown, the imaging module 140 includes a third fine-tuning module 141, a third deflection module 142 and an image acquisition module 143. Both the third fine-tuning module 141 and the third deflection module 142 are arranged on the machine table 110. The image acquisition module 143 is drivingly connected to both the third fine-tuning module 141 and the third deflection module 142. The image acquisition module 143 is used to capture the image formed by the optical lens. The third fine-tuning module 141 can drive the image acquisition module 143 to perform multi-axis movement. For example, the third fine-tuning module 141 can drive the image acquisition module 143 to move along Figure 1 the X, Y, and Z directions as shown, to adjust the relative position relationship between the image acquisition module 143 and the test light source 120 and the lens fixing base 130. The third deflection module 142 can drive the image acquisition module 143 to perform multi-axis deflection. For example, the third deflection module 142 can drive the image acquisition module 143 to rotate around Figure 1 the X and Y directions as shown, to adjust the relative angular relationship between the image acquisition module 143 and the lens fixing base 130.

[0051] The above optical lens testing device 100, through the cooperation of the third fine-tuning module 141 and the third deflection module 142, on the one hand, can adjust the relative positions among the test light source 120, the lens fixing base 130 and the imaging module 140, ensuring that the optical lens, the test light source 120 and the imaging module 140 are on the same optical axis, improving the reliability of the performance test of the optical lens. On the other hand, it can adjust the relative position and angular relationship among the test light source 120, the lens fixing base 130 and the imaging module 140 to simulate the test performance of the optical lens under different light intensity, angle and distance conditions.

[0052] In one embodiment, referring to Figure 1 and Figure 6As shown, the optical lens testing device 100 further includes a loading and unloading module 160. The loading and unloading module 160 is disposed on the machine table 110 by means of welding, screwing, etc. The loading and unloading module 160 is used to feed the optical lens to the lens fixing seat 130 to complete the loading operation of the optical lens to be tested and the unloading operation of the optical lens after the test is completed.

[0053] Specifically, referring to Figure 1 and Figure 6 As shown, the loading and unloading module 160 includes a linear module 161 and a lifting module 162. The linear module 161 has a loading position 1611 and a unloading position 1612 in its extending direction. The lifting module 162 is disposed on the linear module 161, and the lifting module 162 is located at the unloading position 1612. The lifting module 162 is used to lift the optical lens fed to the unloading position 1612 to a position where the lens fixing seat 130 can pick it up. Exemplarily, when a test operation needs to be performed on the optical lens to be tested, first, the optical lens to be tested is loaded at the loading position 1611; then, the linear module 161 feeds the optical lens to be tested at the loading position 1611 to the unloading position 1612; finally, the lifting module 162 lifts the optical lens to be tested at the unloading position 1612 to a position where the lens fixing seat 130 can adsorb and pick it up.

[0054] In one embodiment, referring to Figure 1 As shown, the machine table 110 includes a marble platform 111, a gantry truss 112 and a base 113. The gantry truss 112 is disposed on the marble platform 111. The test light source 120, the lens fixing seat 130 and the imaging module 140 are all disposed on the gantry truss 112. Since the installation space of the gantry truss 112 is large, it will not cause interference to the adjustment of the test light source 120, the lens fixing seat 130 and the imaging module 140, and the gantry truss 112 will not cause interference to the loading and unloading operation of the optical lens. A plurality of adjusting feet 114 are spaced apart along the circumferential direction of the base 113. For example, when there are four adjusting feet 114, the four adjusting feet 114 are respectively located at the four diagonal corners of the base 113. Limited by the difference in the test environment, such as when the machine table 110 is placed on a working platform (usually the working ground), the machine table 110 may have the bad phenomenon of inclination. At this time, the levelness of the base 113 on the working platform can be adjusted by the adjusting feet 114 to ensure the relative position and angular accuracy of the test light source 120, the lens fixing seat 130 and the imaging module 140 during the test process.

[0055] Among them, the marble platform 111 is arranged on the base 113 through a plurality of air floating members 115. The plurality of air floating members 115 are arranged at intervals along the circumferential direction of the marble platform 111. When there are four air floating members 115, the four air floating members 115 are respectively located at the four corners of the marble platform 111. The air floating members 115 can buffer the vibration of the machine table 110 during the test process, and due to the good stability of the marble platform 111, the vibration influence of the machine table 110 during the test process can be further weakened, thereby improving the reliability of the performance test of the optical lens.

[0056] In one embodiment, referring to Figure 1 As shown, the optical lens testing device 100 further includes an environment control unit (not shown in the figure) and a display module (not shown in the figure). The environment control unit and the display module are both arranged on the machine table 110. Since the optical lens is greatly affected by environmental factors during the actual working process, different test environments can be simulated through the environment control unit to perform the performance test of the optical lens in a more realistic test environment. The display module is communicatively connected to the imaging module 140. For example, when the display module is a display screen, the display module is communicatively connected to the imaging module 140 in forms such as cables, WIFI, and Bluetooth. After the imaging module 140 takes a picture of the image formed by the optical lens, the captured image can be transmitted to the display module, and after being processed by the display module, it is visualized to the operator, facilitating the operator to timely master and analyze the advantages and disadvantages of the test performance of the optical lens.

[0057] The following combines Figures 1-6 to describe the test process of the optical lens in this application in detail.

[0058] First, adjust the alignment module 150 so that the collimated light beam emitted by the collimator 153 is perpendicular to the marble platform 111, and calibrate the collimated light beam emitted by the collimator 153; then, adjust the imaging module 140 based on the alignment module 150, such as adjusting the position and angle of the imaging module 140 by combining the collimated light beam emitted by the collimator 153 with the parallel light beams emitted by the three light emitters 154; then, the loading and unloading module 160 feeds the optical lens to be tested from the loading position 1611 to the unloading position 1612, and lifts the optical lens to be tested at the unloading position 1612 to a position where the lens fixing seat 130 can adsorb and pick it up through the lifting module 162, and then, the lens fixing seat 130 is used to lift the optical lens to be tested. 130 picks up the optical lens to be tested by absorption; then, the position and angle of the optical lens and the test light source 120 are determined by shooting with the imaging module 140, such as keeping the optical lens, the test light source 120 and the imaging module 140 on the same optical axis, and using this position as the zero position to test the performance of the optical lens; finally, the relative position and angle relationship between the test light source 120 and the optical lens are adjusted, such as the test light source 120 moves toward the optical lens from near to far, and the optical lens rotates along a 360° circle, while the test light source 120 is deflected from an angle of 0°~90°, and trajectory test points are selected to fit and simulate the test performance of the optical lens under conditions of different light intensities, angles and distances.
