[0021] In order to make the technical problems, technical solutions and beneficial effects of the present application clearer, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0022] In the optical industry, the film layer wear resistance of optical lenses is a crucial performance indicator. Since optical lenses have specific requirements for the wear resistance of the film layer, after the film coating process of optical glass is completed, the film layer must be subjected to wear resistance experiments. Traditional wear resistance experiments often use manual operation, that is, using a specific grinding head to rub the surface of the glass lens under a set pressure, thereby comprehensively testing the wear resistance of the entire surface of the lens. However, manual operation has many unstable factors, such as inaccurate pressure control and unstable rotation speed, which can cause large differences in experimental results and affect the accurate evaluation of the wear resistance of the lens.

[0023] To solve the above problems, the present embodiment provides a glass lens wear resistance testing machine, please see Figs. 1-2 The testing machine includes a box body 1, the box body 1 is provided with a rotary drive mechanism 2, the rotary drive mechanism 2 is connected with a product tooling 3 for placing a glass lens 10, a mounting plate 4 is vertically arranged on the box body 1, the mounting plate 4 is connected with a lifting adjustment mechanism 5, and the lifting adjustment mechanism 5 is connected with a force measuring mechanism 6 corresponding to the product tooling 3.

[0024] In the present embodiment, the rotary drive mechanism 2 connects the product tooling 3 for driving the glass lens to be tested to perform continuous rotary motion. This mechanism achieves constant speed rotation through motor drive, simulating the dynamic friction conditions of the glass lens in actual use. Compared with manual operation, the rotary drive mechanism 2 can provide stable rotation speed, ensuring the consistency of the friction process, thereby significantly improving the reliability of the test results.

[0025] The product fixture 3 is used to fix the glass lens 10 to be tested, which can be adjusted according to different specifications of the lens to adapt to various test requirements. By firmly fixing the glass lens 10 on the product fixture 3, the lens displacement problem that may occur in manual operation can be avoided, and uniform friction can be ensured to act on the lens surface. For example, in some possible embodiments, the product tested by the test machine is a lens with a glass lens 10, and only the corresponding threads in the product fixture 3 need to be machined to switch the detection of the wear resistance of the outermost lens of the lens.

[0026] The lifting adjustment mechanism 5 is used to adjust the height of the force measuring mechanism 6, so that it can adapt to glass lenses of different thicknesses. The lifting adjustment mechanism 5 can be realized by screw drive, air cylinder drive or other common ways, which is simple to operate and has high precision.

[0027] Specifically, the force measuring mechanism 6 includes a force gauge body 61 and a friction part 62. The force gauge body 61 can adopt a common mechanical pressure gauge or an electronic pressure sensor, and preferably adopts a force measuring device integrated with a pressure adjusting device. Compared with a common force measuring device, the pressure value of the force measuring device can be flexibly adjusted according to user requirements, and the applicability is strong. Compared with manual operation, the force gauge body 61 can provide stable friction pressure, avoiding experimental errors caused by uneven force in manual operation.

[0028] Further, the friction part 62 is made of a soft elastic material to facilitate adhesion to the surface of the glass lens when under pressure. The soft elastic material can be at least one of rubber, polyurethane, silicone, foamed polymer or fiber composite material.

The sliding assembly 51 can adopt a linear guide rail, a sliding block or other common linear motion mechanism to ensure that the force measuring mechanism 6 moves smoothly and without deviation during lifting.

[0031] The adjustment assembly 52 connects the sliding assembly 51 and the mounting plate 4, and is used to drive the sliding assembly 51 to move up and down. The adjustment assembly 52 can be realized in the following ways:

[0032] Alternatively, in some embodiments, the adjustment assembly 52 can be a manual adjustment mode, which drives the screw drive through a rotating hand wheel or knob to change the height position of the sliding assembly 51. This way is simple in structure and is suitable for scenes with low requirements for automation.

[0033] Optionally, in some embodiments, the adjusting assembly 52 can be an electric adjusting mode, which realizes precise height adjustment by driving a lead screw or other transmission mechanism through a stepper motor or a servo motor. The electric adjusting mode can be combined with a control system (such as a touch screen or computer software) to realize digital control, which is suitable for high-precision and automated testing requirements.

[0034] Optionally, in some embodiments, the adjusting assembly 52 can be a pneumatic or hydraulic adjusting mode, which drives the sliding assembly 51 to perform lifting movement through a pneumatic cylinder or a hydraulic cylinder, has the characteristics of fast response speed and high stability, and is suitable for testing scenarios requiring frequent height adjustment.

The screw rod 523 is screw-connected between the first connecting piece 521 and the second connecting piece 522, for realizing the height adjustment function of the force measuring mechanism 6. The design of the screw rod 523 enables the operation of the rotating handle 524 to be converted into the up-and-down movement of the fixed plate 513, thereby realizing the precise lifting of the force measuring mechanism 6. The pitch of the screw rod 523 can be selected according to actual requirements, to realize different adjustment accuracy. The rotating handle 524 is arranged at the upper end of the screw rod 523, for manually operating the adjusting assembly 52. By rotating the handle 524, the user can conveniently adjust the height of the force measuring mechanism 6, so that it can adapt to glass lenses of different thicknesses.
