Description

Technical Field

[0001] This invention relates to the field of filter processing technology, specifically to a surface scratch resistance testing device for filters and its usage method. Background Technology

[0002] In the field of filter processing and manufacturing, scratch resistance testing of its surface is a key step in evaluating product quality and durability. However, in actual testing environments, traditional testing equipment often faces many specific problems. Conventional scratch resistance testing equipment typically employs a single rotational friction or a fixed-track reciprocating friction method. While these devices are simple in structure, they fall short when simulating the complex and varied scratching conditions that filters may encounter in actual use. Some devices, although capable of multi-directional movement, have complex transmission mechanisms, low control precision, and difficulty in ensuring stable contact between the test probe and the filter surface throughout the testing process, resulting in inconsistent applied pressure. These problems lead to a single test path and insufficient coverage, making it impossible to conduct a random and comprehensive evaluation of the filter surface. Consequently, the accuracy and reliability of the test results are significantly reduced, making it difficult to truly reflect the scratch resistance performance of the filter. Summary of the Invention

[0003] To address the problems mentioned in the background art, the present invention aims to provide a surface scratch resistance testing device for optical filters and its usage method, which has the advantage of multi-directional rotation testing and solves the problem of incomplete coverage.

[0006] In a preferred embodiment of the present invention, the two side surfaces of the support platform are respectively fixedly connected to the surfaces of the two protective plates, the surface of the servo motor is fixedly connected to the surface of the support platform, and the driving worm, the driven worm wheel and the reciprocating screw are all disposed inside the protective plates.

[0007] In a preferred embodiment of the present invention, the surface of the transmission plate is slidably connected to the interior of the protective plate via a sliding groove, and both ends of the reciprocating screw are rotatably connected to the inner wall of the protective plate.

[0008] In a preferred embodiment of the present invention, the testing mechanism includes a diamond rod, a spring, a connecting plate, a mounting rod, a mating gear, a transmission rack, and a fixing plate. The upper end of the diamond rod is fixedly connected to the upper end of the spring, the lower end of the spring is fixedly connected to the surface of the connecting plate, the inner wall of the connecting plate is fixedly connected to the lower end of the mounting rod, the upper end of the mounting rod is fixedly connected to the surface of the mating gear, the tooth surface of the mating gear meshes with the tooth surface of the transmission rack, and the surface of the transmission rack is fixedly connected to the surface of the fixing plate.

[0009] In a preferred embodiment of the present invention, the surface of the diamond rod is slidably connected to the inner wall of the connecting plate, both ends of the fixing plate are respectively fixedly connected to the upper ends of the two fixing rods, the lower end of the diamond rod is slidably in contact with the surface of the filter, and the surface of the mounting rod is slidably connected to the inner wall of the fixing plate through a groove.

[0010] As a preferred embodiment of the present invention, the testing mechanism is provided with a mating mechanism, which includes a mating plate, a transmission screw, a driving bevel gear, a driven bevel gear, a transmission rod, and a bevel gear set. The inner wall of the mating plate is threadedly connected to the surface of the transmission screw. Both ends of the transmission screw are fixedly connected to the surfaces of the two driving bevel gears, respectively. The tooth surfaces of the driving bevel gears mesh with the tooth surfaces of the driven bevel gears. The inner wall of the driven bevel gear is slidably connected to the surface of the transmission rod through a sliding groove. Both ends of the transmission rod are fixedly connected to the output ends of the two sets of bevel gear sets, respectively.

[0011] In a preferred embodiment of the present invention, the mating gear is disposed inside the mating plate, the lower surface of the mating plate is slidably connected to the upper surface of the fixed plate, both ends of the transmission screw are rotatably connected to the inner wall of the fixed plate through bearing seats, the input end of the bevel gear set is fixedly connected to the surface of the reciprocating screw, both ends of the transmission rod are rotatably connected to the inner wall of the protective plate, and the inner wall of the mounting rod is rotatably connected to the surface of the mating plate through a rotating shaft.

[0012] As a preferred embodiment of the present invention, S1. After the filter processing is completed, samples need to be randomly selected for inspection. First, place the sampled filters on the support platform, then activate the electric push rods on both sides of the support platform. The output ends of the electric push rods begin to retract, sliding along the support platform with the fixed limiting plate. When the limiting plate contacts the filter surface, the filter is fixed in place, preventing it from moving during subsequent testing. S2. Next, start the servo motor on one side of the support platform. The motor drives the two active worm gears to rotate.

When it rotates, it drives the driven bevel gear to rotate as well. The driven bevel gear can slide along the protrusions on the transmission rod and also rotate with the transmission rod. After the driven bevel gear rotates, it drives the driving bevel gears at both ends of the transmission screw. The transmission screw has reciprocating threads, and the mating plate is locked in the threads. When the screw rotates, the mating plate will slide on the fixed plate with the mating gear inside. The mating gear meshes with the transmission rack. As the gear moves, the mounting rod will rotate the connecting plate and the diamond rod. The lower end of the diamond rod slides on the surface of the filter for scratch resistance testing. The spring on the diamond rod will continuously provide downward pressure to ensure that it is in close contact with the filter. Driven by the servo motor, the diamond rod can not only rotate and slide on the surface of the filter, but also move in multiple directions, such as forward, backward, left and right. This allows for a comprehensive scratch resistance test on the surface of the filter.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention solves the problems of single test path and low coverage in traditional filter scratch resistance testing by setting up a multi-degree-of-freedom linkage test structure, and achieves the effect of simulating real complex scratch environment and comprehensively evaluating scratch resistance performance.

[0014] 2. This invention solves the problem of sample displacement leading to decreased accuracy during detection by setting up a clamping mechanism that cooperates with an electric push rod and a limiting plate, thus achieving the effect of quickly and stably fixing the filter and ensuring detection stability.

[0015] 3. By setting up a transmission mechanism composed of a servo motor, a worm gear, and a bevel gear, this invention solves the problems of unstable movement and inconsistent pressure of the test probe, achieving the effect of multi-directional composite motion of the diamond rod while maintaining stable contact.

[0018] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0021] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0022] Example 1

[0023] Reference Figure 1-6 In the first embodiment of the present invention, a support mechanism 1 is provided, including a support platform 101, a filter 102, a limiting plate 103, and an electric push rod 104. The upper surface of the support platform 101 is in contact with the lower surface of the filter 102. The two sides of the filter 102 are in contact with the surfaces of the two limiting plates 103 respectively. The outer end of the limiting plate 103 is fixedly connected to the output end of the electric push rod 104. The surface of the electric push rod 104 is fixedly connected to the outer surface of the support platform 101. The lower surface of the limiting plate 103 is slidably connected to the surface of the support platform 101. Adjustment mechanisms 2 are provided on both sides of the support platform 101. A testing mechanism 3 is provided on the adjustment mechanism 2. The adjustment mechanism 2 is used to adjust the position of the testing mechanism 3. The testing mechanism 3 is used to test the filter 102.

[0024] Specifically, through the coordinated operation of the support platform 101, the electric push rod 104, and the limiting plate 103, the problem of unstable sample fixation and easy displacement leading to decreased detection accuracy during the sampling inspection of the filter 102 is effectively solved. By using the electric push rod 104 to drive the limiting plate 103 to slide, the filter 102 is quickly clamped and positioned, avoiding human operation errors and ensuring the stability of the filter 102 during the test.

[0025] Furthermore, after the processing of the filter 102 is completed, a portion of the samples need to be randomly selected for quality inspection. First, the sampled filter 102 is placed stably on the surface of the support platform 101. Then, the electric push rods 104 preset on both sides of the support platform 101 are activated, causing their output ends to retract. This action will drive the limiting plate 103, which is fixedly connected to the output end, to slide smoothly on the surface of the support platform 101 until the limiting plate 103 is in close contact with the surface of the filter 102. In this way, the filter 102 can be effectively fixed, thereby avoiding unnecessary movement of the filter 102 during subsequent testing and ensuring the stability of the testing environment.

[0026] Example 2

[0027] In a second embodiment of the present invention, an adjustment mechanism 2 is provided, comprising a protective plate 201, a servo motor 202, a driving worm gear 203, a driven worm wheel 204, a reciprocating screw 205, a transmission plate 206, and a fixed rod 207. The surface of the protective plate 201 is fixedly connected to the surface of the servo motor 202. The output end of the servo motor 202 is fixedly connected to the inner wall of the driving worm gear 203. The tooth surface of the driving worm gear 203 meshes with the tooth surface of the driven worm wheel 204. The inner wall of the driven worm wheel 204 is fixedly connected to the surface of the reciprocating screw 205. The surface of the servo motor 202 is threaded to the inner wall of the transmission plate 206. The inner wall of the transmission plate 206 is fixedly connected to the lower end of the fixed rod 207. The two sides of the support platform 101 are fixedly connected to the surfaces of the two protective plates 201 respectively. The surface of the servo motor 202 is fixedly connected to the surface of the support platform 101. The active worm gear 203, the driven worm wheel 204 and the reciprocating screw 205 are all located inside the protective plate 201. The surface of the transmission plate 206 is slidably connected to the inside of the protective plate 201 through a sliding groove. The two ends of the reciprocating screw 205 are rotatably connected to the inner wall of the protective plate 201.

[0028] Specifically, through the precise coordination of the servo motor 202, the driving worm gear 203, the driven worm wheel 204, and the reciprocating screw 205, the problems of low movement accuracy and poor stability of the testing mechanism 3 during the testing process are solved. The adjustment mechanism 2 utilizes the high reduction ratio and self-locking characteristics of the worm gear transmission to achieve precise control of the position of the transmission plate 206, ensuring the stability and positioning accuracy of the testing mechanism 3 when testing on the surface of the filter 102, while improving the reliability of equipment operation and the repeatability of test data.

[0029] Furthermore, after the filter 102 is fixed, the servo motor 202 on one side of the support platform 101 is started, so that its output end drives the two active worm gears 203 fixed thereto to rotate. The active worm gears 203 mesh with the driven worm wheel 204 at one end of the reciprocating screw 205 and transmit power, thereby driving the reciprocating screw 205 to rotate. As the reciprocating screw 205 rotates, the transmission plate 206 with its threaded engagement will slide smoothly in the inner wall of the protective plate 201. Through this transmission process, the transmission plate 206 and the fixed rod 207 connected thereto can be moved synchronously, thereby driving the test mechanism 3 at the upper end of the fixed rod 207 to achieve synchronous displacement, providing a power basis for the subsequent scratch resistance test.

[0030] Example 3

[0031] The third embodiment of the present invention provides a testing mechanism 3 including a diamond rod 301, a spring 302, a connecting plate 303, a mounting rod 304, a mating gear 305, a transmission rack 306, and a fixing plate 307. The upper end of the diamond rod 301 is fixedly connected to the upper end of the spring 302, the lower end of the spring 302 is fixedly connected to the surface of the connecting plate 303, the inner wall of the connecting plate 303 is fixedly connected to the lower end of the mounting rod 304, and the upper end of the mounting rod 304 is fixedly connected to the surface of the mating gear 305. The tooth surface 305 meshes with the tooth surface of the transmission rack 306. The surface of the transmission rack 306 is fixedly connected to the surface of the fixing plate 307. The surface of the diamond rod 301 is slidably connected to the inner wall of the connecting plate 303. Both ends of the fixing plate 307 are fixedly connected to the upper ends of the two fixing rods 207 respectively. The lower end of the diamond rod 301 is in slidable contact with the surface of the filter 102. The surface of the mounting rod 304 is slidably connected to the inner wall of the fixing plate 307 through a sliding groove. The testing mechanism 3 is provided with a mating mechanism 4, which includes a matching... The assembly includes a mating plate 401, a transmission screw 402, a driving bevel gear 403, a driven bevel gear 404, a transmission rod 405, and a bevel gear set 406. The inner wall of the mating plate 401 is threadedly connected to the surface of the transmission screw 402. Both ends of the transmission screw 402 are fixedly connected to the surfaces of the two driving bevel gears 403, respectively. The tooth surfaces of the driving bevel gears 403 mesh with the tooth surfaces of the driven bevel gears 404. The inner wall of the driven bevel gears 404 is slidably connected to the surface of the transmission rod 405 through a sliding groove. Both ends of the transmission rod 405 are respectively... The output ends of the two sets of bevel gear sets 406 are fixedly connected. The mating gear 305 is set inside the mating plate 401. The lower surface of the mating plate 401 is slidably connected to the upper surface of the fixed plate 307. The two ends of the transmission screw 402 are rotatably connected to the inner wall of the fixed plate 307 through bearing seats. The input end of the bevel gear set 406 is fixedly connected to the surface of the reciprocating screw 205. The two ends of the transmission rod 405 are rotatably connected to the inner wall of the protective plate 201. The inner wall of the mounting rod 304 is rotatably connected to the surface of the mating plate 401 through a rotating shaft.

[0032] Specifically, through the coordinated operation of the diamond rod 301, spring 302, and multiple sets of gear transmission mechanisms, the problems of inconsistent contact pressure, single test path, and insufficient coverage in the scratch resistance test of the filter 102 are solved. The test mechanism 3 uses the spring 302 to provide continuous downward pressure to ensure that the diamond rod 301 is in close contact with the surface of the filter 102. At the same time, through the complex gear transmission system, the diamond rod 301 can move in multiple directions while rotating and sliding, so as to randomly and comprehensively conduct scratch resistance tests on the surface of the filter 102.

[0033] Furthermore, bevel gear sets 406 are provided at both ends of the reciprocating screw 205, connecting the reciprocating screw 205 to the transmission rod 405, allowing the reciprocating screw 205 and the transmission rod 405 to rotate simultaneously. A strip-shaped protrusion is formed on the surface of the transmission rod 405. As the transmission rod 405 rotates, it drives the driven bevel gear 404 on its surface to rotate. The inner wall of the driven bevel gear 404 engages with the protrusion on the surface of the transmission rod 405, allowing the driven bevel gear 404 to slide on the surface of the transmission rod 405, while the transmission rod 405 also drives the driven bevel gear 404 to rotate. When the driven bevel gear 404 rotates, it drives the driving bevel gears 403 at both ends of the transmission screw 402 to rotate. The surface of the transmission screw 402 is provided with reciprocating threads, and the transmission screw 402 engages with the inner wall of the mating plate 401. Thus, as the transmission... The rotation of the screw 402 causes the mating plate 401 to drive the mating gear 305 inside to slide on the surface of the fixed plate 307, so that the mating gear 305 meshes with the tooth surface of the transmission rack 306. As the mating gear 305 moves, the mounting rod 304 drives the connecting plate 303 and the diamond rod 301 to rotate, and the lower end of the diamond rod 301 slides on the surface of the filter 102 to perform a scratch resistance test on the filter 102. The spring 302 sleeved on the diamond rod 301 provides it with downward pressure at all times to ensure contact between the diamond rod 301 and the filter 102. Thus, driven by the output end of the servo motor 202, the diamond rod 301 can not only rotate and slide on the surface of the filter 102, but also move in multiple directions in all directions on the surface of the filter 102, ensuring that a comprehensive scratch resistance test can be performed on the surface of the filter 102 at random.

[0034] Working principle: After the processing of filter 102 is completed, a portion of samples need to be randomly selected for quality inspection. First, the sampled filter 102 is placed stably on the surface of the support platform 101. Then, the electric push rods 104 preset on both sides of the support platform 101 are activated, causing their output ends to retract. This action drives the limiting plate 103, which is fixedly connected to the output end, to slide smoothly on the surface of the support platform 101 until the limiting plate 103 is in close contact with the surface of the filter 102. In this way, the filter 102 can be effectively fixed, thereby avoiding unnecessary movement of the filter 102 during subsequent testing and ensuring the stability of the testing environment. After the filter 102 is fixed, the servo motor on one side of the support platform 101 is activated. The machine 202 drives two fixed driving worm gears 203 to rotate at its output end. The driving worm gears 203 mesh with the driven worm wheel 204 at one end of the reciprocating screw 205 to transmit power, thereby driving the reciprocating screw 205 to rotate. As the reciprocating screw 205 rotates, the transmission plate 206 with its threaded engagement surface slides smoothly in the inner wall of the protective plate 201. Through this transmission process, the transmission plate 206 and the fixed rod 207 connected to it can move synchronously, thereby driving the test mechanism 3 at the upper end of the fixed rod 207 to achieve synchronous displacement, providing a power basis for subsequent scratch resistance testing. A bevel gear set 406 is provided at both ends of the reciprocating screw 205, which connects the reciprocating screw 205 and the transmission rod 405. The reciprocating screw 205 and the transmission rod 405 are connected so that they can rotate simultaneously. A strip-shaped protrusion is formed on the surface of the transmission rod 405. As the transmission rod 405 rotates, it drives the driven bevel gear 404 on its surface to rotate. The inner wall of the driven bevel gear 404 engages with the protrusion on the surface of the transmission rod 405. Thus, the driven bevel gear 404 can slide on the surface of the transmission rod 405, and the transmission rod 405 can also drive the driven bevel gear 404 to rotate. When the driven bevel gear 404 rotates, it drives the driving bevel gears 403 at both ends of the transmission screw 402 to rotate. The surface of the transmission screw 402 is provided with a reciprocating thread, and the transmission screw 402 engages with the inner wall of the mating plate 401. Thus, as the transmission screw 402 rotates, the mating plate 402... 01 will cause the internal mating gear 305 to slide on the surface of the fixed plate 307, so that the mating gear 305 meshes with the tooth surface of the transmission rack 306. As the mating gear 305 moves, the mounting rod 304 will drive the connecting plate 303 and the diamond rod 301 to rotate, and the lower end of the diamond rod 301 will slide on the surface of the filter 102 to perform a scratch resistance test on the filter 102. The spring 302 sleeved on the diamond rod 301 will always provide downward pressure to ensure the contact between the diamond rod 301 and the filter 102. Thus, driven by the output end of the servo motor 202, the diamond rod 301 can not only rotate and slide on the surface of the filter 102, but also move in multiple directions in all directions, back and forth and left and right, on the surface of the filter 102.This ensures that the surface of filter 102 can be subjected to comprehensive scratch resistance tests at random.

[0035] In summary, through the coordinated fixation of the electric push rod and the limiting plate, as well as the linkage of mechanical structures such as the servo motor, worm gear, bevel gear set, reciprocating threaded rod and spring-loaded diamond rod, a comprehensive scratch resistance test effect is achieved, allowing the diamond rod to rotate and move in multiple directions during a single test process.

9. A surface scratch resistance testing device for optical filters and its method of use, comprising the surface scratch resistance testing device for optical filters as described in any one of claims 1 to 8, characterized in that: include, S1. After the filter (102) is processed, a sample needs to be randomly selected for inspection. First, place the sampled filter (102) on the support stage (101), and then start the electric push rods (104) on both sides of the support stage (101). The output end of the electric push rod (104) begins to retract, sliding the fixed limiting plate (103) on the support stage (101). When the limiting plate (103) contacts the surface of the filter (102), the filter (102) is fixed, so that it will not move during subsequent testing. S2. Next, start the servo motor (202) on one side of the support platform (101). The motor drives the two active worm gears (203) to rotate. The driven worm gears (204) on the active worm gears (203) and the reciprocating screw (205) mesh with each other, driving the reciprocating screw (205) to rotate. The reciprocating screw (205) is fitted with a transmission plate (206). When the screw rotates, the transmission plate (206) will slide in the inner wall of the protective plate (201). The transmission plate (206) is connected to the fixed rod (207). The two will move together, thereby moving the test mechanism (3) at the upper end of the fixed rod (207) synchronously. S3. The two ends of the reciprocating screw (205) are connected to the transmission rod (405) through the bevel gear set (406), so they can rotate together. The transmission rod (405) has strip-shaped protrusions on its surface. When it rotates, it will drive the driven bevel gear (404) to rotate. The driven bevel gear (404) can slide along the protrusions on the transmission rod (405) and also rotate with the transmission rod (405). After the driven bevel gear (404) rotates, it will drive the driving bevel gears (403) at both ends of the transmission screw (402). The transmission screw (402) has reciprocating threads. The mating plate (401) is stuck in the threads. When the screw rotates, the mating plate (401) will drive the mating gear (305) inside it to the fixed plate ( Sliding on the plate (307), the mounting rod (304) engages with the gear (305) and the transmission rack (306). As the gear moves, the mounting rod (304) rotates with the connecting plate (303) and the diamond rod (301). The lower end of the diamond rod (301) slides on the surface of the filter (102) to perform a scratch resistance test. The spring (302) on the diamond rod (301) will always provide downward pressure to ensure that it is in close contact with the filter (102). Driven by the servo motor (202), the diamond rod (301) can not only rotate and slide on the surface of the filter (102), but also move in multiple directions in the front, back, left and right. This allows for a comprehensive scratch resistance test on the surface of the filter (102) at random.
