Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical lens technology, specifically a thrust testing fixture for the adhesive strength between an optical lens and a metal clamp. Background Technology
[0002] In the field of laser optical path construction, the optical lens is usually fixed by gluing the optical lens to the metal clamp. From the perspective of system reliability, it is necessary to accurately test the bonding strength in engineering applications and perform reliability analysis on the bonded part based on the test results. In the laser production process, due to the different shapes and sizes of optical lenses, there is currently no tooling that can directly test the bonding strength.
[0003] Existing thrust testing devices cannot test optical lenses of different sizes, which is very inconvenient. During the testing process, due to the lack of a buffer structure and the material of the optical lens itself, the optical lens may reach the maximum adhesive viscosity limit when pushed, which may cause the optical lens to break prematurely and affect the accuracy of the test. Therefore, a thrust testing fixture for the adhesive strength between optical lenses and metal clamps is proposed to address the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a thrust testing fixture for the adhesive strength between an optical lens and a metal clamp, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A thrust testing fixture for the adhesive strength of an optical lens to a metal clamp includes a fixed base. A fixed hole is formed at the top of the fixed base. A fixed rod is fixedly connected to the top of the fixed base. A fixed plate is fixedly connected to the top of the fixed rod. A first limiting hole is formed at the top of the fixed plate. A fixed shell is fixedly connected to the top of the fixed plate. A second limiting hole is formed at the bottom of the fixed shell. A first limiting groove, a second limiting groove, a third limiting groove, and a fourth limiting groove are formed inside the fixed shell from bottom to top. A hydraulic rod is fixedly connected to the top of the fixed base at its center. A support rod is fixedly connected to the top of the hydraulic rod, located inside the first and second limiting holes. A pressing plate is fixedly connected to the top of the support rod, located inside the first limiting groove.
[0007] Preferably, a spring is fixedly connected to the top end of the extrusion plate, a connecting plate is fixedly connected to the top end of the spring, and a rubber pad is fixedly connected to the top end of the connecting plate.
[0008] Preferably, the number of springs is several, and they are evenly distributed on the surface of the extrusion plate with the extrusion plate as the center.
[0009] Preferably, there are four fixing rods, which are symmetrically arranged on the surface of the fixing base.
[0010] Preferably, the second, third, and fourth limiting grooves are internally slidably connected by an extrusion plate, a spring, a connecting plate, and a rubber pad.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. In this utility model, by setting components such as a fixed shell, a fixed plate, a first limiting hole, a second limiting hole, a first limiting groove, a second limiting groove, a third limiting groove, and a fourth limiting groove, the appropriate slot is selected according to the size of the optical lens. For larger lenses, the fourth limiting groove can be selected, and for smaller lenses, the third limiting groove can be selected. Taking a small optical lens as an example, firstly, test glue is applied to the third limiting groove, and then the optical lens is glued on it and fixed. After the glue dries, the hydraulic rod drives the support rod to move in the first and second limiting holes. The support rod drives the extrusion plate, the connecting plate, and the rubber pad to move upward. The rubber pad pushes the optical lens to move, thereby testing the adhesive strength between the optical lens and the metal clamp. This solves the problem that the existing thrust testing device cannot test optical lenses of different sizes, which is very inconvenient.
[0013] 2. In this utility model, by using components such as hydraulic rods, support rods, extrusion plates, springs, connecting plates, and rubber pads, the spring between the extrusion plate and the connecting plate reduces the pressure when the rubber pad contacts the optical lens. The rubber pad effectively protects the optical lens and prevents it from being crushed. This solves the problem that existing thrust testing devices, due to the lack of a buffer structure and the material properties of the optical lens itself, may reach the maximum adhesive viscosity limit when pushed, potentially causing the optical lens to break prematurely and affecting the accuracy of the test.

[0021] Please see Figure 1-3 This utility model provides a technical solution:
[0022] A thrust testing fixture for the adhesive strength of an optical lens to a metal clamp includes a fixed base 1, a fixed hole 2 at the top of the fixed base 1, a fixed rod 3 fixedly connected to the top of the fixed base 1, a fixed plate 4 fixedly connected to the top of the fixed rod 3, a first limiting hole 5 at the top of the fixed plate 4, a fixed shell 6 fixedly connected to the top of the fixed plate 4, a second limiting hole 7 at the bottom of the fixed shell 6, and a first limiting groove 8, a second limiting groove 9, a third limiting groove 16 and a fourth limiting groove 17 formed from bottom to top inside the fixed shell 6. A hydraulic rod 10 located at the center is fixedly connected to the top of the fixed base 1, a support rod 11 located inside the first limiting hole 5 and the second limiting hole 7 is fixedly connected to the top of the hydraulic rod 10, and a pressing plate 12 located inside the first limiting groove 8 is fixedly connected to the top of the support rod 11.
[0023] A spring 13 is fixedly connected to the top of the extrusion plate 12, a connecting plate 14 is fixedly connected to the top of the spring 13, and a rubber pad 15 is fixedly connected to the top of the connecting plate 14. There are several springs 13, which are evenly distributed on the surface of the extrusion plate 12 with the extrusion plate 12 as the center. There are four fixing rods 3, which are symmetrically distributed on the surface of the fixing seat 1. The extrusion plate 12, springs 13, connecting plate 14 and rubber pad 15 are slidably connected inside the second limiting groove 9, the third limiting groove 16 and the fourth limiting groove 17.
[0024] Workflow: When using a thrust test fixture to test the adhesive strength between an optical lens and a metal clamp, first, bolts are inserted into fixing holes 2 to fix the fixing base 1 to the ground. Then, the appropriate slot is selected according to the size of the optical lens. For larger lenses, the fourth limiting slot 17 can be selected, and for smaller lenses, the third limiting slot 16 can be selected. Taking a small optical lens as an example, first, test adhesive is applied to the third limiting slot 16, and then the optical lens is glued and fixed in the third limiting slot 16. After the adhesive dries, the hydraulic rod 10 drives the support rod 11 to move within the first limiting hole 5 and the second limiting hole 7. The support rod 11 drives the extrusion plate 12, the connecting plate 14, and the rubber pad 15 to move upward. The rubber pad 15 pushes the optical lens to move. The spring 13 between the extrusion plate 12 and the connecting plate 14 reduces the pressure when the rubber pad 15 contacts the optical lens. The rubber pad 15 effectively protects the optical lens and prevents it from being crushed and damaged. This is used to test the adhesive strength between the optical lens and the metal clamp.
