[0002] An optical lens is a transparent material with one or more curved surfaces made of optical materials such as glass or resin. It is mainly used to refract and reflect light to achieve imaging of objects. When processing optical lenses, optical coating is one of the important processes. Optical coating: As the name suggests, it refers to the process of coating one or more layers of metal (or dielectric) film on the surface of the optical lens. The purpose of optical coating is to change the reflection and transmission characteristics of the lens surface to meet the requirements of reducing or increasing light reflection, beam splitting, color separation, filtering, polarization, etc., and fixtures are required for optical lens coating.

[0003] For the fixture used for optical lens coating, the oversized lens processing fixture for an optical coating machine disclosed in the prior art patent publication number CN211348684U can be used. Because a compression spring is provided, the limiting clamping ring can be pushed to shrink its compression spring, and at the same time, the limit rod moves in the connecting plate. Then, the oversized lens is placed in the fixed clamping ring, and the limiting clamping ring is released to restore its compression spring to push the limiting clamping ring to move and contact the oversized lens, so that the oversized lens is squeezed and clamped between the fixed clamping ring and the limiting clamping ring to complete the fixation, thereby achieving the benefit of facilitating the clamping and fixing of the oversized lens. Because a limiting positioning mechanism is provided, the rotating disk can be rotated to drive the limiting stud to rotate, so that the connecting rod fixed inside the positioning block by the limiting stud can move, and then the connecting rod is rotated to drive the oversized lens to flip, and then the other side of the oversized lens can be coated.

This process is relatively cumbersome, resulting in low coating efficiency. Utility Model Content

The above scheme solves the technical problem that after coating one surface is completed in the prior art, when coating another surface is required, the staff needs to manually rotate the rotating disk to drive the limiting stud to no longer lock the connecting rod, rotate the connecting rod to drive the oversized lens to flip, and then rotate the limiting stud again to lock it before coating the other surface. This process is relatively cumbersome, resulting in low coating efficiency.

[0025] With respect to this specific implementation, when in use, the support frame 101 is used to be placed on the ground for support.

[0026] The support frame 101 has two slide grooves 118, and the two slide plates 105 are respectively slidably connected with the corresponding slide grooves 118. The slide plate 105 has a groove 119. The dual-axis motor 103 is installed on the support frame 101 through the mounting plate 102. The two output ends of the dual-axis motor 103 are respectively fixedly connected with the corresponding telescopic rods 104.

After processing one surface, the dual-axis motor 103 is started, and the dual-axis motor 103 is The output end of 3 drives the two telescopic rods 104 to rotate, and the telescopic rods 104 drive the corresponding driving wheels 106 to rotate, and the driving wheels 106 drive the corresponding driven wheels 107 to rotate through the corresponding belts 108, thereby driving the connecting rod 109 to rotate, and the connecting rod 109 drives the clamping member 110 to rotate. The rotation of the two clamping members 110 can drive the optical lens to flip over, so as to facilitate the processing of the other side. In this way, the optical lens can be turned over more conveniently, thereby improving the coating efficiency.

[0027] Secondly, the box body 111 is fixedly connected to the support frame 101, the box body 111 has a special-shaped groove 120, and the two force-bearing plates 114 are slidably connected to the special-shaped groove 120, one end of the support rod 116 is fixedly connected to the corresponding force-bearing plate 114, the other end of the support rod 116 passes through the box body 111 and is fixedly connected to the corresponding slide plate 105, the two ends of the spring 115 are respectively fixedly connected to the corresponding force-bearing plate 114, the elliptical plate 113 is rotatably connected to the box body 111 through the round rod 112, and the two force-bearing plates 114 are in contact with the elliptical plate 113.

The two force-bearing plates 114 drive the spring 115 to extend and drive the two support rods 116 to move relative to each other. The two support rods 116 drive the two slide plates 105 to move relative to each other. When clamping, the round rod 112 is rotated in the opposite direction. At this time, the elliptical plate 113 no longer abuts against the two force-bearing plates 114. The spring 115 resets and contracts to drive the two force-bearing plates 114 to move toward each other, thereby driving the two slide plates 105 to move toward each other through the two connecting rods 109.
