[0018] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0019] See also Figure 1-3 The present embodiment provides a technical solution: a coating fixture for processing plastic lenses, comprising a base 1, support seats 2 are fixed at both ends of the left and right ends of the base 1, a support unit 4 is installed in the middle of the base 1, a mounting seat driving mechanism 5 is installed on each support seat 2, a mounting seat 9 is provided at the end of the mounting seat driving mechanism 5, a servo motor 7 is installed on the side of the mounting seat 9, a clamp 8 is fixed on the output shaft of the servo motor 7, and the clamp 8 is a rubber clamp, a connecting rod 10 is fixed on the side of the mounting seat 9, and scales 11 are evenly arranged on the connecting rod 10, the connecting rod 10 is connected to the support seat 2 for left and right sliding, and a limit mechanism 6 is provided on the connecting rod 10, a power switch group 3 is installed on the side of one of the support seats 2, the power switch group 3 is electrically connected to an external power supply, and the servo motor 7 is electrically connected to the power switch group 3.

[0020] The support unit 4 includes a first electric push rod 41 and a support platform 42. The first electric push rod 41 is installed in the middle of the base 1. The support platform 42 is fixed to the telescopic end of the first electric push rod 41. The first electric push rod 41 is electrically connected to the power switch group 3. The plastic lens is placed on the support platform 42. The telescopic end of the first electric push rod 41 drives the support platform 42 to move up and down, thereby lifting the plastic lens to a position corresponding to the clamp 8, which can send the plastic lens to the corresponding position according to different thicknesses.

[0021] The mounting seat driving mechanism 5 includes a second electric push rod 51, a slide groove 52 and a sliding seat 53. The slide groove 52 is opened on the support seat 2. There are two slide grooves 52 located on the same support seat 2. The sliding seat 53 is slidably connected with the slide groove 52. The second electric push rod 51 is installed at the end of the support seat 2. The telescopic end of the second electric push rod 51 is fixedly connected to the sliding seat 53. The second electric push rod 51 is electrically connected to the power switch group 3. The mounting seat driving mechanism 5 also includes a first pin shaft 54, a connecting rod 55 and a second pin shaft 56. One end of the connecting rod 55 is rotatably connected to the sliding seat 53 through the first pin shaft 54, and the other end of the connecting rod 55 is rotatably connected to the mounting seat 9 through the second pin shaft 56. The telescopic end of the second electric push rod 51 drives the sliding seat 53 to move, and the sliding seat 53 slides along the slide groove 52. The sliding seat 53 drives the mounting seat 9 to move through the connecting rod 55. The mounting seat 9 drives the connecting rod 10 to slide with the support seat 2. During the movement of the mounting seat 9, the connecting rod 55 is connected to the first pin shaft 54 The second electric push rod 51 stops working when the two clamps 8 are close to each other to clamp and fix the plastic lens. In this fixed state, the two clamps 8 can fix the plastic lens stably without causing the plastic lens to break due to excessive clamping force. After coating one mirror surface, the support table 42 returns to its original position driven by the first electric push rod 41, thereby providing space for the flipping of the plastic lens. Then, the output shaft of the servo motor 7 drives the clamp 8 to rotate, thereby flipping the plastic lens. Then, the other mirror surface of the plastic lens can be coated. This avoids the trouble of manually rotating the fixing plate to drive the clamping plate. The plastic lens can be flipped during the fixing process, thereby avoiding the trouble of releasing the plastic lens and flipping it over. This saves time and effort, thereby improving the processing efficiency.

[0022] The limiting mechanism 6 includes a limiting block 61 and a locking screw 62. The limiting block 61 is sleeved on the connecting rod 10 and is slidably connected to the connecting rod 10. The locking screw 62 is assembled on the limiting block 61 and locks the limiting block 61 on the connecting rod 10. The position of the limiting block 61 on the connecting rod 10 is adjusted according to the plastic lenses of different sizes. The limiting block 61 is accurately adjusted by the scale 11 on the connecting rod 10. After the adjustment is completed, the limiting block 61 is locked on the connecting rod 10 by the locking screw 62. At this time, the moving length of the connecting rod 10 to the position of the plastic lens is limited, and the spacing between the two clamps 8 when they are against the plastic lens is designed. At this time, the two clamps 8 will not crush the plastic lens when fixing it, thereby avoiding the loss caused by the breakage of the plastic lens.

[0023] The working principle of the coating fixture for processing plastic lenses provided by the utility model is as follows: the plastic lens is placed on the support platform 42, and the telescopic end of the first electric push rod 41 drives the support platform 42 to perform lifting movement, so as to lift the plastic lens to a position corresponding to the fixture 8, and then the telescopic end of the second electric push rod 51 drives the sliding seat 53 to move, and the sliding seat 53 slides along the slide groove 52, and the sliding seat 53 drives the mounting seat 9 to move through the connecting rod 55, and the mounting seat 9 drives the connecting rod 10 to slide with the support seat 2. During the movement of the mounting seat 9, the connecting rod 55 rotates relative to the sliding seat 53 through the first pin shaft 54, and the connecting rod 55 rotates relative to the mounting seat 9 through the second pin shaft 56, until the limit block 61 contacts the support seat 2, and the second electric push rod 51 stops working. At this time, the two fixtures 8 approach each other to clamp and fix the plastic lens. In this fixed state, the two clamps The fixture 8 can stably fix the plastic lens without causing the plastic lens to break due to excessive clamping force. After coating one mirror surface, the support table 42 returns to its original position driven by the first electric push rod 41, thereby providing space for the flipping of the plastic lens. Then, the output shaft of the servo motor 7 drives the fixture 8 to rotate, thereby flipping the plastic lens. Then, the other mirror surface of the plastic lens can be coated. The position of the limit block 61 on the connecting rod 10 is adjusted according to the plastic lenses of different sizes. The limit block 61 is accurately adjusted by the scale 11 on the connecting rod 10. After the adjustment is completed, the limit block 61 is locked on the connecting rod 10 by the locking screw 62. At this time, the moving length of the connecting rod 10 to the position of the plastic lens is limited, and the distance between the two fixtures 8 when they are against the plastic lens is designed. At this time, the two fixtures 8 will not crush the plastic lens when fixing the plastic lens.
