The first pressing member 235 is arranged on the slider 231, and the slider 231 slides on the slide rail 234. When the first lens fixture 280 needs to be placed, the sliding clamping mechanism 230 is close to the clamping and releasing mechanism 260, so that the abutting end 261 of the clamping and releasing mechanism 260 abuts against the guide surface 233 of the first pressing member 235 of the sliding clamping mechanism 230, so that the first pressing member 235 compresses the reset spring 232 and drives the second pressing member 236 to move toward the fixed block 250.

When the first sliding seat 220 is away from the clamping and releasing mechanism 260, the first pressing member 235 is separated from the pressing state of the clamping and releasing mechanism 260, so that the second pressing member 236 is reset and abuts against the first lens fixture 280, so that the first lens fixture 280 is in a clamped state; during the dust removal process, there is no need to manually clamp the VR glasses, which avoids the dust on the hands from being contaminated on the VR glasses, is conducive to automated operation, reduces the generation of dust particles, and is conducive to dust removal.

[0043] The use process of the lens transfer module provided by the utility model is as follows:

[0044] The first lens fixture 280 with the lens is placed in the positioning member 240, and the sliding clamping mechanism 230 is close to the clamping and releasing mechanism 260, so that the abutting end 261 of the clamping and releasing mechanism 260 abuts against the guide surface 233 of the first pressing member 235 of the sliding clamping mechanism 230, so that the first pressing member 235 slides on the slide seat through the slider 231, compressing the return spring 232 and driving the second pressing member 236 to move toward the fixed block 250. At this time, the external manipulator places the first lens fixture 280 on the positioning member 240 for preliminary positioning. When the first pressing member 235 of the sliding clamping mechanism 230 is away from the clamping release mechanism 260, the first pressing member 235 is slid and reset under the action of the elastic force of the two reset springs 232. Then, the second pressing member 236 abuts against the first lens clamp 280, so that the first lens clamp 280 is fixed on the positioning member 240. The first lens clamp 280 can be pressed and fixed on the positioning member 240, which is conducive to automatic clamping without manual intervention.

[0045] Please refer to Figure 1 and Figure 2 In this embodiment, the abutting end 261 of the clamping and releasing mechanism 260 is provided with a pulley. In this embodiment, the abutting end 261 is provided with a pulley, and the abutting end 261 is used to apply a pressure to the guide surface 233 of the first pressing member 235 while avoiding excessive friction, thereby avoiding damage to the machine and improving durability. The first pressing member 235 of the sliding clamping mechanism 230 is in a trapezoidal shape, and the guide surface 233 is an inclined surface. The left and right guide surfaces 233 are used to cooperate with the abutting end 261 to obtain a stable pressing state for displacement, and to clamp or release the first lens clamp 280.

[0046] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A clearance groove 270 is provided adjacent to the clamping cavity of the positioning member 240. The clearance groove 270 is suitable for facilitating the robot to load and unload the first lens fixture 280.

The rotating motor 330 and the cylinder clamp 340 are arranged on the second sliding seat 320. The output end of the rotating motor 330 is transmission-connected to the cylinder clamp 340.

[0049] The second lens fixture 350 is clamped on the cylinder clamp 340, and the rotary motor 330 is used to control the rotation of the cylinder clamp 340, so as to realize the flipping of the second lens fixture 350, and the second linear slide rail module 310 is used to provide a sliding platform for the second sliding seat 320, and the second sliding seat 320 is used to provide a fixed platform for the rotary motor 330, which is conducive to adsorbing dust on the upper and lower surfaces in the dust removal head module 100, and is conducive to cleanliness. It is worth mentioning that the transfer assembly 300 can be used independently or in conjunction with the lens transfer module 200. For example, an external manipulator places the second lens fixture 350 equipped with the lens on the cylinder clamp 340, and after dusting the first side of the lens, the lens is turned over by driving the rotating motor 330 to facilitate dusting the second side. For another example, the lens transfer module 200 performs dust removal on the first side of the lens accommodated in the first lens fixture 280, and then the external manipulator transfers the first lens fixture 280 from the positioning piece 240 of the lens transfer module 200 to the cylinder clamp 340 of the transfer assembly 300 to flip it over and complete the dust removal of the second side of the lens.
