Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lens testing, in particular to a lens testing device for smart wearable products. BACKGROUND

[0002] A lens is a core optical component of a smart wearable device, and a lens for a smart watch is also called a watch lens. The lens not only needs to have excellent optical imaging quality, but also must have sufficient mechanical strength to resist scratches, impacts and other damages. Therefore, in the product research and development and production quality control links, the lens needs to be tested for imaging performance and scratch damage threshold.

[0003] The existing scratch damage threshold method usually adopts single-point static scratch testing, or needs to manually transfer the lens to another device for strength testing after applying the scratch. It is difficult to accurately control the gradualness of the scratch, and the lens state cannot be monitored in real time during the scratch generation process, resulting in low threshold determination efficiency and large error.

[0004] The smart wearable watch lens is curved. When light enters the arc-shaped watch lens from the edge, the thickness of the watch lens will significantly affect the actual incidence angle of the light at the edge, thereby indirectly changing the refraction angle. If the thickness of the watch lens deviates too much from the standard value, it will significantly affect the light refraction path and imaging quality. Poor imaging quality will cause distortion of the image on the display screen, affecting user use. The conventional testing method needs to adjust the lens position multiple times or use multiple groups of sensors. The light path calibration is complex and it is difficult to achieve efficient scanning of the global refraction anomaly.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0038] Embodiment, refer to Figures 1 to 11 A testing device for a lens of an intelligent wearable product, comprising a base 1 and a watch mirror 2, the surface of the base 1 is provided with a mounting seat 3 and a waste conveying belt 4, the output end of the waste conveying belt 4 penetrates the shell of the base 1, the mounting seat 3 is provided with a composite action assembly, the lower part of the mounting seat 3 is provided with a multi-station turntable 8, a plurality of test cavities are formed in the interior of the multi-station turntable 8, a positioning groove 9 is formed in the test cavity, a positioning hole is formed in the inner side wall of the positioning groove 9, a vacuum suction assembly is arranged below the positioning groove 9, a test cover 5 is arranged below the multi-station turntable 8, a plurality of load applying grooves 7 and a through hole are formed in the lower surface of the test cover 5, a test ring 6 is arranged in the through hole, an imaging test assembly, a force applying action cylinder 10 and a photoelectric sensor group are arranged on the inner side wall of the test ring 6, a spherical pressure head is arranged at the output end of the force applying action cylinder 10, and a feeding assembly is arranged below the test cover 5.

[0039] The imaging test assembly comprises a light path assembly, and the input end of the light path assembly is obliquely provided with a laser emitter 11.

[0040] The vacuum suction assembly comprises a positioning suction seat 12 with an open bottom, the positioning suction seat 12 is fixedly installed in the test cavity, and a suction action rod 13 is slidably connected to the interior of the positioning suction seat 12.

[0041] It should be noted that the waste conveying belt 4 is a skirt conveying belt in the prior art, and the diameter of the positioning suction seat 12 is smaller than the diameter of the watch mirror 2.

[0042] Further, the feeding assembly comprises a positioning conveyor belt 14 and a lifting swing arm 15, the positioning conveyor belt 14 is fixedly connected with the surface of the base 1, the input end of the positioning conveyor belt 14 penetrates the shell of the base 1, the lifting swing arm 15 is fixedly installed on the surface of the base 1, the end of the lifting swing arm 15 is provided with a rotary joint, the outer side wall of the rotary joint is installed with a suction actuator 16, and the suction actuator 16 is installed with a vacuum chuck inside;

[0043] Further, the load applying groove 7 is fixedly installed with a pressing spring, the top of the pressing spring is fixedly connected with a single-cone scratch indenter 17, and the single-cone scratch indenter 17 is in sliding connection with the load applying groove 7.

[0044] The further benefits of the above are that the stable and controllable scratch pressure can be provided by the pressing spring, and the single-cone scratch indenter 17 can form the scratch gradually deepening on the surface of the table mirror 2 in the continuous rotation process of the multi-station turntable 8, so as to provide the damage condition for the subsequent determination of the scratch damage threshold of the table mirror 2.

[0045] Further, the inner side wall of the test cavity is fixedly installed with a support, the support is located below the positioning suction seat 12, the lower surface of the support is fixedly installed with a pivotal reflecting mirror 18, the pivotal reflecting mirror 18 can guide the edge-refracted laser beam to each guide mirror 22 in the light path assembly when the table mirror 2 is intact, and the pivotal reflecting mirror 18 can guide the laser beam emitted by the laser emitter 11 to the fragmentation sensor 25 when the table mirror 2 is broken, so as to provide the light path condition for the subsequent determination of the imaging performance of the table mirror 2.

[0046] Further, the upper portion of the suction action rod 13 is fixedly installed with a positioning sliding block 19, the positioning sliding block 19 is in sliding connection with the positioning groove 9, the positioning sliding block 19 is installed with a plurality of positioning pins matched with positioning holes, and the positioning pins can mechanically lock the suction action rod 13 through the meshing with the positioning holes after the positioning sliding block 19 is raised, so as to avoid that the positioning suction seat 12 loses the suction function due to the lowering of the suction action rod 13, and the lower portion of the suction action rod 13 is fixedly installed with a piston.

[0047] Further, the composite action assembly comprises a limiting groove opened in the mounting seat 3, the lower portion of the limiting groove is provided with a bidirectional electromagnetic coil 20, and the limiting groove is in sliding connection with a push core 21, and the bidirectional electromagnetic coil 20 can drive the suction action rod 13 to rise to form the negative pressure in the positioning suction seat 12 after being electrified.

[0048] It should be noted that the bidirectional electromagnetic coil 20 adopts a direct current power supply mode, the realization of the bidirectional action depends on the control of the current direction of the input coil through the direct current switching power supply, when the current direction changes, the polarity of the magnetic field generated inside the coil will be reversed, thereby changing the working direction, and this principle will not be described below.

[0049] The further advantage of the above-mentioned method is that, during loading, after the linear lifting mechanism pushes the watch lens 2 into place, the bidirectional electromagnetic coil 20 is energized, and the magnetic force drives the adsorption action rod 13 and the piston to rise synchronously, forming a stable negative pressure environment for adsorption between the watch lens 2 and the positioning adsorption seat 12. At the same time, the positioning pin on the positioning slider 19 automatically engages with the positioning hole in the positioning groove 9 to complete the mechanical locking. During unloading, it is only necessary to change the current direction of the input coil, and the magnetic force drives the pusher core 21 to move downward. Its thrust first overcomes the locking force of the positioning pin to unlock, and then pushes the adsorption action rod 13 and the piston to reset, realizing the linkage control of magnetic vacuum adsorption and mechanical locking, and improving the clamping efficiency.

[0050] Furthermore, a limiting plate is fixedly installed on the top of the pusher core 21, and a return spring is fixedly connected to the bottom of the limiting plate. The bottom of the return spring is fixedly connected to the limiting groove.

[0051] Furthermore, the optical path assembly consists of multiple guide mirrors 22 and incident mirrors 23. The guide mirrors 22 and incident mirrors 23 are fixedly installed on the inner wall of the test ring 6 in the form of a ring array. The guide mirrors 22 and incident mirrors 23 in the ring array form a cyclic test optical path, and the laser penetrates different areas of the watch mirror 2 multiple times.

[0052] It should be noted that: the guide mirror 22 and the incident mirror 23, as Figure 10 As shown, the tilt state of the guide mirror 22 is calibrated so that its reflective surface matches the optical path of the laser beam after being reflected by the pivot mirror 18 and then refracted by the dial mirror 2. The mirror reflects the received laser beam to the incident mirror 23, and the incident mirror 23 guides the reflected beam from the guide mirror 22 back to the dial mirror 2 through its specific tilt angle, thereby forming a complete test optical path. This principle will not be elaborated further below.

[0053] Furthermore, the photoelectric sensor group includes an imaging sensor 24 and a fragmentation sensor 25 installed on the inner sidewall of the test ring 6. The imaging sensor 24 is located at the output end of the optical path assembly, and the fragmentation sensor 25 is located on the reflected light path of the pivot mirror 18. The independent fragmentation sensor 25 can capture the laser beam that has only undergone one reflection by taking advantage of the fact that the light path is not refracted after the surface mirror 2 is broken.

[0054] The further advantage of adopting the above is that by setting up independent imaging sensors 24 and fragmentation sensors 25, dual-modal parallel monitoring of imaging performance testing and fragmentation event detection is realized. Imaging sensor 24 is used to detect refraction anomalies to determine imaging quality, while fragmentation sensor 25 is used to accurately capture the changes in light signals after the mirror 2 is broken, ensuring the independence and accuracy of the two test results.

[0055] It should be noted that: Figure 10 and Figure 11 The dashed line in the image represents the laser beam.

[0056] When the present application is in use, the lifting swing arm 15 is lowered to make the adsorption executor 16 contact and adsorb the surface mirror 2 on the surface of the positioning conveying belt 14, after the adsorption is completed, the lifting swing arm 15 is raised and rotated horizontally by 180° along the base 1, at the same time, the driving rotary joint is driven to rotate vertically by 180° to make the output direction of the adsorption executor 16 align with the positioning adsorption seat 12, then the lifting swing arm 15 pushes the surface mirror 2 to rise until the surface mirror 2 contacts the positioning adsorption seat 12, at this time, the bidirectional electromagnetic coil 20 is energized, the adsorption action rod 13 is pulled up by magnetic force, the adsorption action rod 13 drives the piston to rise synchronously, a negative pressure environment is formed between the surface mirror 2 and the positioning adsorption seat 12, the negative pressure adsorbs the surface mirror 2 stably in the test cavity, after the adsorption action rod 13 completes the rising action, the positioning sliding block 19 is mechanically locked by the engagement of the positioning pin and the positioning groove 9, which can prevent the surface mirror 2 from moving or loosening during the test;

[0057] After the feeding of this station is completed, the laser emitter 11 emits a laser beam, the laser beam passes through the surface mirror 2 and is reflected by the pivotal mirror 18 to irradiate on the surface of the guide mirror 22, the guide mirror 22 reflects the light beam to the incident mirror 23 through a specific inclination. After the incident mirror 23 receives the light beam, it is redirected back to the surface mirror 2 through a specific inclination, the laser beam repeats the above process until it is reflected by the last incident mirror 23 in the array to the imaging sensor 24 through the pivotal mirror 18, thereby forming a test light path repeatedly passing through the surface mirror 2 from different directions, when the laser is incident into the surface mirror 2 through a low incidence angle, the thickness of the surface mirror 2 will significantly affect the actual incidence angle of the light at the edge, thereby indirectly changing the refraction angle, the change of the refraction angle at any position will cause the imaging sensor 24 to fail to receive the light signal, if the imaging sensor 24 does not receive the signal, it indicates that the imaging performance of the surface mirror 2 is unqualified, indicating that the surface mirror 2 is polished too thick or too thin, the imaging test process will not be described hereinafter;

[0058] After the imaging test of this station is completed, the multi-station turntable 8 is rotated by 45° to position the next station, and the feeding and imaging test are sequentially performed, and the process is repeated until all stations complete the imaging test, then the multi-station turntable 8 performs the scratch damage threshold determination action;

[0059] When the scratch damage threshold determination is performed, the multi-station turntable 8 carries the table mirror 2 in each station to rotate synchronously, and when the multi-station turntable 8 is in a continuous rotation state, each table mirror 2 will periodically pass the position of the load applying groove 7. When the table mirror 2 moves to the position above the load applying groove 7, the surface of the table mirror 2 will push the single-cone scratch indenter 17 to move downward. In this process, the single-cone scratch indenter 17 moves downward and compresses the pressing spring, and the compressed pressing spring generates a reaction force. This force is transmitted to the surface of the table mirror 2 through the tapered tip of the single-cone scratch indenter 17. Since the multi-station turntable 8 is continuously rotating, the table mirror 2 moves transversely relative to the fixed single-cone scratch indenter 17. The tapered tip of the single-cone scratch indenter 17 scratches the surface of the moving table mirror 2 under the action of the constant spring force, thereby forming a scratch. After multiple continuous rotations of the multi-station turntable 8, the surface of the table mirror 2 will form a concentric circular arc-shaped scratch with gradually increasing depth, i.e., a scratch with gradually increasing depth. After the multi-station turntable 8 rotates for a period of time, the following test actions are performed:

[0060] After the multi-station turntable 8 is positioned at the test area by using the encoder in the prior art, the laser emitter 11 and the force applying cylinder 10 work simultaneously. After the force applying cylinder 10 is elongated, the spherical indenter is used to press the table mirror 2. After the pressing is completed, the multi-station turntable 8 is rotated by 45°.

[0061] After the above test actions are performed for 8 times, the multi-station turntable 8 continues to rotate. During the continuous rotation, the single-cone scratch indenter 17 forms a scratch with gradually increasing depth on the surface of the table mirror 2.

[0062] Then, the test actions are performed again. When the table mirror 2 is crushed by the indenter, air enters from the broken part, causing the positioning suction seat 12 to lose its function. At this time, the broken table mirror 2 falls into the waste conveying belt 4 under the action of gravity. The light beam of the laser emitter 11 is not refracted due to the absence of the table mirror 2, and thus directly irradiates the surface of the pivotal reflector 18 and is reflected to the fragmentation sensor 25. The fragmentation sensor 25 receives the light signal and transmits data. The scratch damage threshold of the table mirror 2 at this position is calculated by the program. After all the table mirrors 2 are broken, the scratch damage threshold determination is completed, and the equipment is reset by the composite action assembly.

[0063] When the equipment is reset, the input coil current direction is changed by the direct current switching power supply, and the magnetic force is used to drive the push core 21 to move vertically downward. The pushing force applied by the push core 21 is greater than the locking force of the positioning pin, so that the positioning pin is separated from the positioning hole and the locking state is released. Subsequently, the push core 21 continues to move downward and pushes the suction action rod 13 and the piston to descend until the reset.

[0064] The above merely describes preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art, according to the technical solution and inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
