Description

Technical Field

[0001] This utility model relates to the field of optical lens processing technology, specifically to an infrared imaging optical lens grinding fixture. Background Technology

[0002] Grinding fixtures for infrared imaging optical lenses are crucial in optical manufacturing because they help ensure the lenses maintain their correct shape and positioning during the grinding process. Currently, the fixtures used in the grinding process of infrared imaging optical lenses typically employ mechanical clamping or vacuum clamping. When using mechanical clamping to hold the surface of infrared imaging optical lenses, excessive clamping force can easily cause indentation damage to the surface, while insufficient force can easily cause the lenses to detach from the fixture during grinding. Vacuum clamping reduces the risk of damage to the surface of infrared imaging optical lenses caused by excessive force. However, the clamping area of ​​the infrared imaging optical lens by the vacuum chuck is relatively concentrated, and under the influence of the grinding pressure, the infrared imaging optical lens is prone to detaching from the vacuum chuck, thereby reducing the stability of the infrared imaging optical lens during the grinding process and indirectly affecting the effectiveness of the grinding fixture.

[0003] Therefore, it is necessary to develop an infrared imaging optical lens grinding fixture. Utility Model Content

[0022] This utility model provides the following technical solution: an infrared imaging optical lens grinding fixture, please refer to... Figures 1-4The equipment includes a grinding equipment base 1, a side frame 2 mounted on one side of the top of the grinding equipment base 1, a guide groove 201 formed on the outer wall surface of one side of the side frame 2, left and right threaded rods 202 rotatably connected inside the side frame 2, a motor A203 mounted on the top of the side frame 2, and the output shaft of the motor A203 fixedly connected to the top of the left and right threaded rods 202 via a coupling. Mounting plates 3 are mounted on the upper and lower sides of one side of the outer wall of the side frame 2, a turntable 301 rotatably connected to the center of the interior of the mounting plate 3, a guide seat 302 mounted on one side of the outer wall of the mounting plate 3, the outer wall of the guide seat 302 slidably connected to the inner wall of the guide groove 201, and a movable seat 303 mounted on one side of the outer wall of the guide seat 302, the interior of the movable seat 303 threadedly connected to the outer wall of the left and right threaded rods 202, thus allowing the guide seats 302 on one side of the outer wall of the two mounting plates 3 to slide. The guide groove 201 on the side frame 2 is connected to the guide seat 302 and the movable seat 303 on the guide seat 302 is installed on the outer wall of the left and right threaded rods 202 by means of threaded connection. According to the left and right threaded rods 202 having a left thread at the top and a right thread at the bottom, the motor A203 drives the left and right threaded rods 202 to rotate forward or reverse, which can synchronously drive the two sets of mounting plates 3 to move outward or inward. The top of the upper mounting plate 3 is equipped with a mounting bracket 304, and the top center of the mounting bracket 304 is equipped with a motor B305. The output shaft of the motor B305 is fixedly connected to the top center of the turntable 301. The motor B305 is installed on the mounting bracket 304 on the upper mounting plate 3, and the output end of the motor B305 is fixedly connected to the turntable 301 inside the mounting plate 3, so that the motor B305 can drive the turntable 301 to rotate forward or reverse.

[0023] A bracket 4 is mounted at the center of the surface of the turntable 301. A vacuum tube 401 is mounted at the center of the surface of the bracket 4. A vacuum suction cup 402 is mounted at one end of the vacuum tube 401, and a connecting tube 403 is mounted at the other end of the vacuum tube 401. The connecting tube 403 is located inside the bracket 4. A clamp 404 is slidably connected to one side of the outer wall of the vacuum tube 401, and a spring 405 is provided on the other side of the outer wall of the vacuum tube 401. An anti-slip washer 406 is provided at one end of the clamp 404. The clamp 404 is slidably mated to the outer wall of the vacuum tube 401, and the spring 405 is fitted between the clamp 404 and the bracket 4 on the outer wall of the vacuum tube 401. Since the clamp 404 is lower than the vacuum suction cup 402 on the vacuum tube 401, the infrared imaging optical lens to be ground is placed between the upper and lower clamps 404. Motor A20 3. Drive control: Two sets of clamps 404 are connected to each other to clamp the infrared imaging optical lens. After clamping, motor A203 drives the two sets of clamps 404 to connect again, so that the internal vacuum suction cup 402 contacts and vacuum adsorbs the surface of the infrared imaging optical lens, thus achieving clamping and fixing of the infrared imaging optical lens. The infrared imaging optical lens is clamped and fixed simultaneously by mechanical and vacuum clamping. During mechanical clamping, spring 405 and anti-slip washer 406 are used to buffer and protect the surface of the infrared imaging optical lens, so as to avoid the mechanical clamping causing indentation damage to the surface of the infrared imaging optical lens, and also to avoid the vacuum suction cup adsorbing area being too concentrated, which may easily cause one side to be pressed and detach.

[0024] Working principle: When using this utility model, the guide seats 302 on one side of the outer wall of the two sets of mounting plates 3 are slidably connected to the guide grooves 201 on the side frame 2, and the movable seats 303 on the guide seats 302 are threadedly installed on the outer wall of the left and right threaded rods 202. Since the upper part of the left and right threaded rods 202 has a left thread and the lower part has a right thread, the motor A203 drives the left and right threaded rods 202 to rotate forward or backward, which can synchronously drive the two sets of mounting plates 3 to move outward or inward. The motor B305 is installed on the mounting bracket 304 on the upper mounting plate 3, and the output end of the motor B305 is connected to the mounting bracket 304. The turntable 301 inside plate 3 is fixedly connected, allowing motor B305 to drive and control the turntable 301 to rotate forward or backward. The clamp 404 is slidably docked onto the outer wall of vacuum tube 401, and a spring 405 is fitted between the clamp 404 and the bracket 4 on the outer wall of vacuum tube 401. Since the clamp 404 is lower than the vacuum suction cup 402 on vacuum tube 401, the infrared imaging optical lens to be ground is placed between the upper and lower clamps 404. Motor A203 drives and controls the two sets of clamps 404 to dock with each other, allowing for the clamping of the infrared imaging optical lens. The clamped infrared imaging optical lens... Motor A203 drives the two sets of clamps 404 to dock together, until the internal vacuum suction cup 402 contacts and vacuum-adsorbs the surface of the infrared imaging optical lens, thus achieving the clamping and fixing of the infrared imaging optical lens. The infrared imaging optical lens is simultaneously clamped and fixed using both mechanical and vacuum clamping methods. During mechanical clamping, springs 405 and anti-slip washers 406 provide cushioning and protection for the surface of the infrared imaging optical lens, minimizing the risk of indentation damage and preventing the vacuum suction cup from concentrating in one area. This can lead to one side being pressed and causing detachment. Simultaneously, after the infrared imaging optical lens is clamped and fixed, during the grinding operation, motor B305 can drive and control the rotation of the infrared imaging optical lens to adjust its position. It should be noted that motor B305 is driven in a half-turn mode; for example, rotating half a turn and then resetting, followed by a right half-turn rotation, ensures that the outer ring of the infrared imaging optical lens can be ground. Furthermore, the driving method does not affect the external vacuum conveying pipe connected to connecting pipe 403. This effectively improves the clamping stability during the grinding process of the infrared imaging optical lens and indirectly improves the performance of the infrared imaging optical lens grinding fixture.

In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
