Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-4This utility model provides a technical solution: a positioning device for polishing optical lenses, comprising: a placement component 1 and a polishing component 2. The placement component 1 includes a placement stage 101, an air hole 102, a filter screen 103, an inner hole 104, an electric rod 105, a soft pad 106, an inner cavity 107, and a vacuum pump 108. The top of the placement stage 101 is provided with an air hole 102, and a filter screen 103 is fixedly disposed inside the air hole 102. The number of air holes 102 and filter screens 103 are both provided in multiples. Each lens is evenly distributed on the placement platform 101. The top of the placement platform 101 has an inner hole 104 located inside the multiple air holes 102. An electric rod 105 is fixedly installed inside the inner hole 104. A soft pad 106, made of wear-resistant and high-temperature-resistant rubber, is fixedly connected to the top of the electric rod 105. The soft pad 106 is sealed to the inner hole 104. When the electric rod 105 is activated, the soft pad 106 moves upward, thus smoothly lifting the optical lens for easy removal. Below, the placement stage 101 has an inner cavity 107. An air vent 102 penetrates the placement stage 101 and communicates with the inner cavity 107. A vacuum pump 108 is fixedly connected to the bottom of the placement stage 101. The input end of the vacuum pump 108 penetrates the placement stage 101 and communicates with the inner cavity 107. When the vacuum pump 108 is started, the air in the inner cavity 107 and below the optical lens can be drawn away, thus creating a negative pressure zone. Under atmospheric pressure, the optical lens can be stably fixed on the placement stage 101 without... This will cause bending deformation of the optical lens, thereby improving the polishing accuracy. The bottom of the placement stage 101 is fixedly connected to a shock absorber 3, and the bottom of the shock absorber 3 is fixedly connected to an electric suction cup 4. There are multiple shock absorbers 3 and electric suction cups 4, which are symmetrically distributed at the four corners of the bottom of the placement stage 101. When the electric suction cup 4 is activated, the placement stage 101 can be fixed steadily. During the polishing process, the shock absorber 3 can effectively reduce vibration, thereby making the polishing more stable and improving the polishing accuracy.
[0025] The polishing assembly 2 includes a back plate 201, a top plate 202, an electro-hydraulic rod 203, a movable plate 204, a polishing motor 205, and a polishing disc 206. The front sidewall of the back plate 201 is fixedly connected to the placement stage 101. The top plate 202 is fixedly connected to the top of the back plate 201. The electro-hydraulic rod 203 is fixedly connected to the bottom of the top plate 202. The movable plate 204 is fixedly connected to the bottom of the electro-hydraulic rod 203. The polishing motor 205 is fixedly connected to the bottom of the movable plate 204. The polishing disc 206 is fixedly connected to the bottom output end of the polishing motor 205. The polishing disc 206 is located above the placement stage 101. When the electro-hydraulic rod 203 is activated, the movable plate 204, the polishing motor 205, and the polishing disc 206 move downwards. At the same time, the polishing motor 205 is activated to rotate the polishing disc 206, thereby polishing the optical lens below.
[0026] Working principle: The optical lens is placed on the placement stage 101, covering the air vent 102. The electric suction cup 4 is activated to firmly fix the placement stage 101. The vacuum pump 108 is activated to remove the air from the inner cavity 107 and below the optical lens, thus creating a negative pressure zone. Under atmospheric pressure, the optical lens can be firmly fixed on the placement stage 101 without bending or deforming. The electric hydraulic rod 203 is activated, and the moving plate 204, polishing motor 205, and polishing disc 206 move downward. At the same time, the polishing motor 205 is activated to rotate the polishing disc 206, thereby polishing the optical lens below. The shock absorber 3 can reduce the vibration generated during the polishing process, making the polishing more stable. After polishing is completed, the electric rod 105 is activated to move the soft pad 106 upward, thereby smoothly lifting the optical lens for easy removal. The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
