[0002] During the use of lenses, it is inevitable that they will be contaminated with dust and other substances. Therefore, lenses often need to be wiped. However, the wiping process will cause friction to the lenses and damage the mirror surface of the lens surface. Therefore, the abrasion resistance of the lens is an important indicator to judge the quality of the lens. Therefore, it is necessary to conduct abrasion tests on the lens surface.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a 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 those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0021] Existing wear-resistant detection equipment can only perform a measured friction test on the lens, which cannot meet the need to compare the wear resistance of the lens, and it is impossible to more intuitively observe how much wear resistance the lens can withstand, and there are certain limitations in the detection process.

[0022] In view of this, the present invention provides a lens wear resistance detection device. Through the cooperation of weights, springs and steel wool, when it is necessary to detect the wear resistance effects that the lens can withstand at different levels, the weights on the top of the baffle can be increased step by step. The weight compresses the spring downward to make the steel wool rub the lens, and the wear resistance level that the lens can withstand can be detected according to the different weights of the weights.

[0023] By those skilled in the art, the components in this case are connected in sequence. For the specific connection and operation sequence, reference should be made to the following working principle. The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process.

[0024] Embodiment 1: As Figure 1-4 It can be seen that a lens wear resistance detection device includes a base 1. The top of the base 1 is fixedly connected with an outer shell 9. A friction device is arranged above the base 1. The friction device includes a baffle 3, a connecting rod 4, a weight 5, steel wool 14, a disc 16, a spring 17 and a sleeve 18. The inner wall of the sleeve 18 is inserted with a connecting rod 4. The outer wall of the connecting rod 4 is fixedly connected with a baffle 3. The baffle 3 is installed above the sleeve 18. The top of the baffle 3 is attached to a weight 5. The weight 5 is sleeved on the outer wall of the connecting rod 4. The weight 5 can move freely on the outer wall of the connecting rod 4 to increase or decrease the weight 5. The bottom of the connecting rod 4 is fixedly connected with a disc 16. The bottom of the disc 16 is fixedly connected with a spring 17. The weight 5 applies downward pressure to compress the spring 17 at the bottom of the disc 16. The other end of the spring 17 is fixedly connected with steel wool 14;

[0025] In the specific implementation process, it is worth particularly pointing out that the base 1, as the installation carrier of other structures, can be directly placed on the workbench or placed at the designated position by erecting support legs. The baffle 3 is installed on the outer wall of the connecting rod 4, and its purpose is to limit the weight 5, facilitating the weight 5 to be sleeved on the outer wall of the connecting rod 4. Multiple weights 5 can be set, and an appropriate number can be selected according to requirements and sleeved on the connecting rod 4. In this way, the overall gravity of the connecting rod 4, the disc 16, the spring 17, and the steel wool 14 is increased. Under the action of gravity, the connecting rod 4 moves downward along the sleeve 18, thereby pressing the steel wool 14 against the surface of the lens. By changing the number of weights 5, the pressure between the steel wool 14 and the lens is changed, and thus friction tests with different forces are realized.

[0026] Furthermore, a lever 6 is fixedly connected to the side of the sleeve 18. A housing 7 is sleeved on the outer wall of the lever 6. The lever 6 can freely adjust its length according to the position where the lens is placed, so that the steel wool 14 is located directly above the lens. A straight rod 11 is inserted into the side of the housing 7 away from the sleeve 18, and the straight rod 11 is rotatably connected to the housing 7. A turntable 12 is arranged below the housing 7. One side of the straight rod 11 is movably connected to the top groove of the turntable 12. The lower side of the straight rod 11 away from the connecting rod 4 is rotatably connected to a screw rod 10 through a bearing. The screw rod 10 is threadedly connected to the side of the turntable 12. By rotating the screw rod 10, the position of the straight rod 11 at the groove of the turntable 12 is adjusted, achieving the adjustment of the friction range of the steel wool 14. The bottom of the turntable 12 is fixedly connected to a servo motor 15, and the servo motor 15 is installed inside the base 1;

[0027] In the specific implementation process, it is worth particularly pointing out that when detecting the wear resistance of the lens, the servo motor 15 is started to make the turntable 12 rotate. Through the rotation of the turntable 12, the straight rod 11 at the top groove of the turntable 12 can drive the housing 7 and the lever 6 to perform reciprocating movements, so as to achieve that the steel wool 14 fixedly connected to one end of the lever 6 can reciprocally rub on the top of the lens. By rotating the screw rod 10, the position of the straight rod 11 at the groove of the turntable 12 is adjusted, achieving the adjustment of the friction range of the steel wool 14;

[0028] Furthermore, a limiting member 8 fixedly connected to the top of the outer shell 9 is installed on one side of the turntable 12 close to the steel wool 14. The housing 7 penetrates through the side of the limiting member 8. Limiting rods 13 are fixedly connected to the upper and lower inner walls of the limiting member 8. The other ends of the limiting rods 13 are movably connected to the surface grooves of the housing 7. When the housing 7 reciprocates in the circular hole opened in the limiting member 8, the limiting rods 13 can ensure the regular movement of the housing 7;

[0029] In the specific implementation process, it is particularly worth noting that when the housing 7 reciprocates in the round hole opened in the limiting member 8, the limiting rods 13 fixed to the upper and lower inner walls of the round hole opened in the limiting member 8 can move at the grooves opened on the surface of the housing 7, so as to ensure that the housing 7 moves regularly and there will be no deviation in the friction range.

[0030] Specifically, when using this lens abrasion resistance testing device, start the servo motor 15 to make the turntable 12 rotate. Through the rotation of the turntable 12, the straight rod 11 at the groove on the top of the turntable 12 can drive the housing 7 and the lever 6 to reciprocate, so as to achieve that the steel wool 14 fixed to one end of the lever 6 can reciprocally rub on the top of the lens. By rotating the screw rod 10 to adjust the position of the straight rod 11 at the groove of the turntable 12, the friction range of the steel wool 14 can be adjusted. When the housing 7 reciprocates in the round hole opened in the limiting member 8, the limiting rods 13 fixed to the upper and lower inner walls of the round hole opened in the limiting member 8 can move at the grooves opened on the surface of the housing 7, so as to ensure that the housing 7 moves regularly and there will be no deviation in the friction range. When testing the different friction forces of the lens, the number of weights 5 on the top of the baffle 3 can be increased or decreased, so as to increase or decrease the overall gravity of the connecting rod 4, the disc 16, the spring 17 and the steel wool 14 part and the pressure transmitted by the steel wool 14 to the lens.

[0031] Embodiment 2: As Figure 1-4 It can be seen that a convex slide rail 2 is fixedly connected to the top of the base 1, and a fixing plate 20 is slidably clamped to the top of the convex slide rail 2. A cylinder 21 is fixedly connected to the side of the fixing plate 20 away from the housing 9, and the cylinder 21 is fixedly connected to the top of the base 1;

[0032] In the specific implementation process, it is particularly worth noting that when the detection work needs to be carried out, start the cylinder 21 to push the fixing plate 20 to slide on the convex slide rail 2 to fix the lens placed on the top of the base 1;

[0033] Furthermore, fixing members 19 are slidably clamped to the sides of the fixing plate 20 and the housing 9 close to each other, and the fixing members 19 can be replaced according to the model of the lens;

[0034] In the specific implementation process, it is particularly worth noting that there are many types of lens specifications and models. When carrying out the abrasion resistance test, the fixing member 19 at the groove of the fixing plate 20 can be replaced according to the lens model to ensure that the lens will not loosen or deviate during the friction process;

[0035] Specifically, on the basis of the above-mentioned first embodiment, when the detection work needs to be carried out, the air cylinder 21 is started to push the fixed plate 20 to slide on the convex slide rail 2 to fix the lens placed on the top of the base 1. The fixing member 19 at the groove of the fixed plate 20 can also be replaced according to the lens model to ensure that the lens will not loosen or shift during the friction process.
