Description

Technical Field

[0001] The present invention relates to the field of lens testing technology, and in particular to a testing device for lenses used in smart wearable products. Background Art

[0002] Lenses are the core optical components of smart wearable devices. Lenses used in smartwatches, also known as watch lenses, must not only have excellent optical imaging quality but also possess sufficient mechanical strength to resist damage from scratches and impacts. Therefore, during product development and production quality control, lenses must be tested for imaging performance and scratch damage thresholds. Existing scratch damage threshold methods typically use single-point, static scratch testing, or require manual transfer of the lens to another device for strength testing after the scratch is applied. This makes it difficult to accurately control the progressiveness of the scratch and unable to monitor the lens status in real time during the scratch generation process, resulting in low threshold determination efficiency and large errors. Smart wearable watch lenses are curved. When light enters the curved lens from the edge, the thickness of the lens significantly affects the actual incident angle of the light at the edge, thereby indirectly changing the refraction angle. If the thickness of the lens differs significantly from the standard value, it will significantly affect the light refraction path and image quality. Poor image quality will cause image distortion on the display screen, affecting user experience. Conventional testing methods require multiple adjustments to the lens position or the use of multiple sets of sensors. This complicates optical path calibration and makes it difficult to achieve efficient scanning of refraction anomalies over the entire area. To this end, a testing device for lenses for smart wearable products is proposed, which uses a destructive testing method to solve the above problems in the random inspection process.

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] In the description of the present invention, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "mounted / connected," and "connected" should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention in specific circumstances.

[0021] Example, see Figures 1 to 11 , a testing device for lenses for smart wearable products, including a machine base 1 and a mirror 2, a mounting seat 3 and a waste conveyor belt 4 are provided on the surface of the machine base 1, the output end of the waste conveyor belt 4 passes through the shell of the machine base 1, a composite action component is provided in the mounting seat 3, a multi-station turntable 8 is provided below the mounting seat 3, a plurality of test cavities are provided inside the multi-station turntable 8, a positioning groove 9 is provided in the test cavity, a positioning hole is provided on the inner side wall of the positioning groove 9, a vacuum adsorption component is provided below the positioning groove 9, a test cover 5 is provided below the multi-station turntable 8, a through hole and a plurality of load application grooves 7 are provided on the lower surface of the test cover 5, a test ring 6 is provided in the through hole, an imaging test component, a force-applying cylinder 10 and a photoelectric sensor group are provided on the inner side wall of the test ring 6, a spherical pressure head is provided at the output end of the force-applying cylinder 10, and a loading component is provided below the test cover 5; The imaging test assembly includes an optical path assembly, and a laser emitter 11 is obliquely arranged at the input end of the optical path assembly; The vacuum adsorption assembly includes a positioning adsorption seat 12 with an open bottom. The positioning adsorption seat 12 is fixedly installed in the test chamber. An adsorption action rod 13 is slidably connected to the interior of the positioning adsorption seat 12 .

[0022] It should be noted that the waste conveyor belt 4 is a skirt conveyor belt in the prior art, and the diameter of the positioning adsorption seat 12 is smaller than the diameter of the watch mirror 2 .

[0023] Furthermore, the loading assembly includes a positioning conveyor belt 14 and a lifting swing arm 15. The positioning conveyor belt 14 is fixedly connected to the surface of the machine base 1. The input end of the positioning conveyor belt 14 passes through the shell of the machine base 1. The lifting swing arm 15 is fixedly installed on the surface of the machine 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 an adsorption actuator 16. A vacuum suction cup is installed in the adsorption actuator 16. Furthermore, a pressure spring is fixedly installed in the load application groove 7, and a single-cone scratching indenter 17 is fixedly connected to the top of the pressure spring. The single-cone scratching indenter 17 is slidably connected to the load application groove 7; A further benefit of adopting the above method is that a stable and controllable scratching pressure can be provided by the pressure spring, and in conjunction with the single-cone scratch indenter 17, a gradually deepening scratch is formed on the surface of the watch glass 2 during the continuous rotation of the multi-station turntable 8, providing damage conditions for the subsequent measurement of the scratch damage threshold of the watch glass 2.

[0024] Furthermore, a bracket is fixedly mounted on the inner wall of the test chamber. The bracket is located below the positioning adsorption seat 12. A pivot reflector 18 is fixedly mounted on the lower surface of the bracket. When the mirror 2 is intact, the pivot reflector 18 can guide the laser beam refracted by the edge to each guide mirror 22 in the optical path assembly. When the mirror 2 is broken, the pivot reflector 18 can guide the laser beam emitted by the laser emitter 11 to the fragmentation sensor 25, thereby providing optical path conditions for subsequent measurement of the imaging performance of the mirror 2. Furthermore, a positioning slider 19 is fixedly installed above the adsorption action rod 13, and the positioning slider 19 is slidably connected to the positioning groove 9. A plurality of positioning pins matching the positioning holes are installed in the positioning slider 19. After the positioning slider 19 rises, the positioning pins can mechanically lock the adsorption action rod 13 by engaging with the positioning holes, thereby preventing the fixed adsorption action rod 13 from falling and causing the positioning adsorption seat 12 to lose its adsorption function. A piston is fixedly installed below the adsorption action rod 13; Furthermore, the composite action assembly includes a limiting groove provided in the mounting seat 3, a bidirectional electromagnetic coil 20 is provided below the limiting groove, a push core 21 is slidably connected in the limiting groove, and the bidirectional electromagnetic coil 20 can drive the adsorption action rod 13 to rise when energized to form a negative pressure in the positioning adsorption seat 12; It should be noted that the bidirectional electromagnetic coil 20 adopts a DC power supply method, and the realization of its bidirectional action depends on controlling the current direction of the input coil through a DC switching power supply. When the current direction changes, the polarity of the magnetic field generated inside the coil will reverse accordingly, thereby changing the working direction. This principle will not be repeated below.

[0025] A further benefit of adopting the above method is that when loading, after the linear lifting mechanism pushes the watch mirror 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 adsorption negative pressure environment between the watch mirror 2 and the positioning adsorption seat 12. At the same time, the positioning pin on the positioning slider 19 automatically engages the positioning hole in the positioning groove 9 to complete the mechanical locking. When discharging, it is only necessary to change the current direction of the input coil, and the magnetic force will drive the push core 21 downward. Its thrust first overcomes the locking force of the positioning pin to achieve unlocking, and then pushes the adsorption action rod 13 and the piston to reset, realizing the linkage control of magnetically controlled vacuum adsorption and mechanical locking, and improving the clamping efficiency.

[0026] Furthermore, a limit plate is fixedly installed on the top of the push core 21, a return spring is fixedly connected to the bottom of the limit plate, and the bottom of the return spring is fixedly connected to the limit groove; Furthermore, the optical path assembly is composed of a plurality of guide mirrors 22 and incident mirrors 23. The guide mirrors 22 and incident mirrors 23 are fixedly mounted on the inner wall of the test ring 6 in the form of an annular array. The guide mirrors 22 and incident mirrors 23 in the annular array form a circular test optical path, and the laser penetrates different areas of the watch mirror 2 multiple times. It should be noted that: the guide mirror 22 and the incident mirror 23 are as follows: Figure 10 In the arrangement 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 it is reflected by the hub reflector 18 and refracted by the surface mirror 2. The mirror reflects the received laser beam to the incident mirror 23, and the incident mirror 23 redirects the reflected light beam from the guide mirror 22 back to the surface mirror 2 through its specific tilt angle, thereby forming a complete test optical path. This principle will not be repeated below.

[0027] Furthermore, the photoelectric sensor group includes an imaging sensor 24 and a fragmentation sensor 25 mounted on the inner side wall 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 in the reflected light path of the pivot reflector 18. The independent fragmentation sensor 25 utilizes the characteristic of no refraction in the optical path after the mirror 2 is broken, and can capture the laser beam that has only undergone a single reflection. A further benefit of adopting the above method is that, by providing independent imaging sensors 24 and fragmentation sensors 25, dual-modal parallel monitoring of imaging performance testing and fragmentation event detection is achieved. The imaging sensor 24 is used to detect refraction anomalies to determine imaging quality, while the fragmentation sensor 25 is used to accurately capture the changes in the optical signal after the watch mirror 2 is broken, thereby ensuring the independence and accuracy of the two test results.

[0028] It should be noted that: Figure 10 and Figure 11 The dashed line in is used to represent the laser beam.

[0029] When the present invention is in use, the lifting swing arm 15 descends to allow the adsorption actuator 16 to contact and adsorb the watch mirror 2 on the surface of the positioning conveyor belt 14. After the adsorption is completed, the lifting swing arm 15 rises and rotates 180 degrees horizontally along the machine base 1, and at the same time drives the rotary joint to rotate 180 degrees vertically to align the output direction of the adsorption actuator 16 with the positioning adsorption seat 12. Then the lifting swing arm 15 pushes the watch mirror 2 to rise until the watch mirror 2 contacts the positioning adsorption seat 12. At this time, the bidirectional electromagnetic coil 20 is energized, and the adsorption action rod 13 is pulled up by magnetic force. The adsorption action rod 13 drives the piston to rise synchronously, forming a negative pressure environment between the watch mirror 2 and the positioning adsorption seat 12. The negative pressure firmly adsorbs the watch mirror 2 in the test chamber. After the adsorption action rod 13 completes the rising action, the positioning slider 19 is firmly mechanically locked by the engagement of the positioning pin and the positioning groove 9, which can prevent the watch mirror 2 from occurring or loosening during the test process. After completing the loading process at this station, the laser emitter 11 emits a laser beam. The laser beam passes through the watch mirror 2 and is reflected by the pivot reflector 18 before irradiating the surface of the guide mirror 22. The guide mirror 22 reflects the beam to the incident mirror 23 at a specific tilt. After receiving this beam, the incident mirror 23 redirects it back to the watch mirror 2 at a specific tilt. The laser beam repeats this process until it is reflected by the last incident mirror 23 in the array. After that, it is reflected by the pivot reflector 18 to the imaging sensor 24, thus forming a test light path that repeatedly passes through the watch mirror 2 from different directions. When the laser beam enters the watch mirror 2 at a low incident angle, the thickness of the watch mirror 2 will significantly affect the actual incident angle of the light at the edge, thereby indirectly changing the refraction angle. Any change in the refraction angle at any position will cause the imaging sensor 24 to be unable to receive the light signal. If the imaging sensor 24 does not receive a signal, it indicates that the imaging performance of this watch mirror 2 is unqualified, indicating that the watch mirror 2 is polished too thick or too thin. This imaging test process will not be further described below. After the imaging test of this station is completed, the multi-station turntable 8 rotates 45 degrees to locate the next station, and performs loading and imaging tests in sequence. This process is repeated until all stations have completed the imaging test, and then the multi-station turntable 8 performs the scratch damage threshold measurement action; When measuring the scratch damage threshold, the multi-station turntable 8 carries the watch mirror 2 of each station and rotates synchronously. When the multi-station turntable 8 is in a continuous rotation state, each watch mirror 2 will periodically pass the position of the load application slot 7. When the watch mirror 2 moves above the load application slot 7, its surface will push the single-cone scratch indenter 17 to move downward. During this process, the single-cone scratch indenter 17 moves downward and squeezes the pressure spring. The compressed pressure spring generates a reaction force, which is transmitted through the conical tip of the single-cone scratch indenter 17. The test piece is passed to the surface of the watch crystal 2. As the multi-station turntable 8 continues to rotate, the watch crystal 2 moves laterally relative to the fixed single-cone scratch indenter 17. Under the action of a constant spring pressure, the conical tip of the single-cone scratch indenter 17 scratches the moving surface of the watch crystal 2, thereby forming a scratch. After multiple continuous rotations of the multi-station turntable 8, a concentric arc-shaped scratch with gradually increasing depth will be formed on the surface of the watch crystal 2, that is, a progressively deepening scratch. After the multi-station turntable 8 rotates for a period of time, the following test actions are performed: After the multi-station turntable 8 uses an encoder in the prior art to locate a station in the test area and stops, the laser emitter 11 and the force-applying cylinder 10 work simultaneously. After the force-applying cylinder 10 extends, it uses the spherical indenter to squeeze the table mirror 2. After the squeezing is completed, the multi-station turntable 8 rotates 45 degrees; After the above test action is performed 8 times, the multi-station turntable 8 continues to rotate. During the continuous rotation process, the single-cone scratch indenter 17 forms a gradually deepening movement path (scratch) on the surface of the watch glass 2; The test action is then performed again. When the watch mirror 2 is crushed by the pressure head, air enters from the broken part, causing the positioning adsorption seat 12 to lose its function. At this time, the broken watch mirror 2 falls onto the scrap conveyor belt 4 under the action of gravity. The light beam of the laser emitter 11 is no longer affected by the watch mirror 2 and is not refracted. Instead, it directly illuminates the surface of the hub reflector 18 and is reflected to the fracture sensor 25. After receiving the light signal, the fracture sensor 25 uploads the data. The program calculates the scratch damage threshold of the watch mirror 2 at this location. After all the watch glasses 2 are broken, the scratch damage threshold measurement is completed, and the device is reset through the composite action component. When the device is reset, the direction of the current in the input coil is changed by the DC switching power supply, and the push core 21 is driven by magnetic force to move vertically downward. The thrust applied by the push core 21 is greater than the locking force of the positioning pin, so that the positioning pin is disengaged from the positioning hole and the locked state is released. Subsequently, the push core 21 continues to move downward, pushing the adsorption action rod 13 and the piston down until it is reset.

[0030] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
