Description
Technical Field
[0001] This utility model relates to the field of lens polishing technology, specifically to a device for polishing the edges and corners of light-transmitting materials. Background Technology
[0002] With the development of technology, light-transmitting materials are increasingly widely used in the optical field, such as lenses and lens elements. When our company uses an automatic alignment machine for lens assembly, we have found that some lenses have burrs on their edges, causing the assembled lenses to deviate from their intended position or not fit properly with the lens holder. To solve this problem, the usual practice is to collect the lenses and reprocess them. In this reprocessing process, the lenses are magnetically fixed on a rotary processing table, and fine abrasive blades are used to polish the edges. However, this polishing method easily results in irregularities at the lens edges, leading to a high reject rate. During processing on the rotary table, the lenses experience vibrations due to the force applied, which can cause wavy processing shapes at the lens edges, affecting the processing quality. Furthermore, the polishing efficiency is low, making it difficult to meet the needs of large-scale production. Utility Model Content

Detailed Implementation
[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Various changes can be made to the implementation scheme as long as the effects of the present invention can be achieved.
[0032] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.
[0033] Reference Figure 1-6 This embodiment describes a device for grinding the edges and corners of translucent materials.
[0034] like Figure 1As shown, it includes a base 8 and a placement stage 9 disposed on the base 8. The placement stage 9 is a processing stage in the prior art that adsorbs and fixes light-transmitting material and rotates it. The light-transmitting material is a flat circular lens.
[0035] like Figure 1 and Figure 2 As shown, a base 5 fixed on a platform 8 is provided on one side of the placement platform 9, a second motor 6 is provided on the top of the base 5, and a polishing head 10 for polishing the light-transmitting material is provided at the output end of the second motor 6.
[0036] Furthermore, such as Figure 2 As shown, a strip-shaped slot 13 is opened on the top of the base 5, and a slide rail 12 is fixed to the inner wall of the strip-shaped slot 13; a slider 11 is fixed to the bottom outer wall of the second motor 6, and the slider 11 is slidably connected to the slide rail 12; an electric telescopic rod 7 is fixed to the top of the base 5, and the output end of the electric telescopic rod 7 is fixed to the second motor 6. After the light-transmitting material is adsorbed and fixed on the placement platform 9, the electric telescopic rod 7 pushes the second motor 6 to move on the slide rail 12 through the slider 11, so that the grinding head 10 is close to the light-transmitting material to grind its edges and corners.
[0037] In this embodiment, the grinding head 10 is as follows: Figure 3 As shown, the system includes a base 101 fixedly connected to the output end of the second motor 6. A stepped platform is formed on the base 101, and a grinding ring and a pressure ring 102 for fixing the grinding ring are stacked on the platform. The pressure ring 102 is fixed to the base 101 by a pin 106. The pin 106 is used to connect the pressure ring 102 to ensure that the pressure ring 102 does not rotate when the grinding head 10 rotates, thus ensuring the stability of the pressing action on the grinding ring.
[0038] Specifically, the polishing ring includes an upper polishing ring 103 and a lower polishing ring 104 stacked on top of each other. The upper polishing ring 103 and the lower polishing ring 104 have opposing arc-shaped surfaces 105 at their edges, and the two arc-shaped surfaces 105 form a concave semicircular surface, which is adapted to the circumferential edge of the light-transmitting material.
[0039] Furthermore, the inner walls of the upper polishing ring 103 and the lower polishing ring 104 are polygonal, and the contact surfaces of the substrate 101 with the upper polishing ring 103 and the lower polishing ring 104 are adapted to the inner walls of the polygons. This polygonal contact surface design ensures that the upper polishing ring 103 and the lower polishing ring 104 do not rotate when in contact with the light-transmitting material.
[0040] like Figure 1 As shown, a lifting device 1 is provided on the other side of the placement platform 9, and an assembly frame 2 is fixed on the moving end of the lifting device 1. The lifting device 1 is a ball screw slide, and the moving end is a movable slider fixed on the ball screw nut.
[0041] like Figure 4 As shown, a first motor 3 is fixed on the assembly frame 2, and a clamping frame 4 is provided below the assembly frame 2. The main shaft axis of the first motor 3 is located on the same center line as the center of the placement table 9.
[0042] like Figure 5 As shown, the clamping frame 4 includes a positioning platform 41, at least two fixed plates 42, at least two beam arms 43, a threaded rod 47, a movable plate 44, and at least two movable connecting beams 45. In a preferred embodiment, there are three beam arms 43, and the number of fixed plates 42 and connecting beams 45 corresponds to the number of beam arms 43. The positioning platform 41 is fixed to the assembly frame 2. Each fixed plate 42 is equidistantly distributed on the bottom surface of the positioning platform 41. One end of each beam arm 43 is hinged to a fixed plate 42, and the other end is provided with a claw head 46. The threaded rod 47 is rotatably connected to the positioning platform 41 and connected to the output end of the first motor 3. The movable plate 44 is threadedly connected to the threaded rod 47. One end of each connecting beam 45 is hinged to the movable plate 44, and the other end is hinged to a beam arm 43.
[0043] During operation, the first motor 3 drives the threaded rod 47 to rotate on the positioning table 41. The forward and reverse rotation of the first motor 3 causes the movable plate 44 to move up and down on the threaded rod 47. When the movable plate 44 moves up and down, the angle between the connecting beam 45 and the beam arm 43 is adjusted, so that the beam arm 43 swings around the fixed plate 42 as the axis. When it swings inward, the claw head 46 at the bottom clamps the edge of the light-transmitting material. When the light-transmitting material rotates on the placement table 9 and is polished by the grinding head 10, the clamping of the edge of the light-transmitting material by the claw head 46 prevents the light-transmitting material from vibrating, ensuring the polishing effect of the edge of the light-transmitting material.
[0044] In a preferred embodiment, such as Figure 6 As shown, the claw head 46 has an opening, and a filler 48 is disposed inside the opening. A retainer 49 is fixed inside the filler 48, and a ball bearing 410 is rotatably disposed inside the retainer 49. Opening slots 411 are opened on both sides of the claw head 46, and the opening slots 411 communicate with the opening.
[0045] The edge of the light-transmitting material is embedded in the opening groove 411 and abuts against the upper and lower balls 410. When the light-transmitting material rotates, the balls 410 clamp and fix the edge of the light-transmitting material to prevent it from vibrating.
[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
