The coating liquid is sprayed on the surface of the optical component through the nozzle 1361, thereby coating the optical component.

[0049] See also Figure 1 , Figure 2 , Figure 3 A water tank 112 is fixedly connected to the top of the outer wall of the box body 100, and a water filling port 1121 is fixedly opened on the upper surface of the water tank 112. A connecting pipe 1262 is longitudinally fixedly connected to the surface of the first piston cylinder 126. The top of the connecting pipe 1262 extends to the outside of the box body 100 and is fixedly connected to the water tank 112. The outer wall of one end of the first piston cylinder 126 away from the water outlet pipe 1261 is fixedly sleeved with a fixed sleeve rod 1263 fixedly connected to the upper surface of the movable plate 134, and a first one-way valve is fixedly installed at the contact position between the connecting pipe 1262 and the water tank 112.

[0050] Water can be added to the water tank 112 through the water inlet 1121.

[0056] After the optical components are rinsed, the movable plate 134 descends, and the first metal iron sheet 1342 contacts the second metal iron sheet. The fan 115 is turned on, and the fan 115 cooperates with the air outlet duct 1151 to blow air to the optical components, thereby drying the optical components.

[0057] See also Figure 1 , Figure 2 , Figure 3 , Figure 4A groove 110 is provided on the front surface of the box body 100, and a box door 111 is rotatably connected to the inner wall of the groove 110. A handle 1111 is fixedly connected to the surface of the box door 111. A fan 115 is fixedly installed on the inner wall of the box body 100 on a side away from the liquid storage box 113. An air outlet duct 1151 is fixedly installed on the surface of the fan 115 on a side away from the box body 100. An ultraviolet lamp 116 is fixedly installed on the inner wall of the box body 100 above the fan 115.

[0058] When the optical components need to be coated, the box door 111 is opened, the optical components are placed on the placement tray 1272, the optical components are clamped by the clamping block 1232, and the surface is cleaned. After cleaning, the optical components are dried by the fan 115. After drying, the optical components are coated and used. After coating, the ultraviolet lamp 116 is turned on to facilitate the curing of the optical components by the ultraviolet lamp 116.

[0059] A method for coating an optical component comprises the following steps:

[0060] Substrate processing: The first piston rod cooperates with the first piston cylinder to spray water from the water storage tank to clean the optical components and remove surface impurities and dust;

[0061] S2: substrate drying: the movable plate is driven down by the one-way threaded rod, and the blower is started by the action of the first metal iron sheet and the second metal iron sheet, so as to dry the surface of the optical component;

[0062] S3: Coating operation: After drying is completed, the movable plate rises, so that the coating liquid inside the second piston cylinder is sprayed onto the surface of the optical component through the action of the second piston rod, thereby performing a coating operation on the optical component;

[0063] S4: Curing treatment: After the coating is completed, the limit of the optical components is cancelled, and the optical components are cured by turning on the ultraviolet lamp. At the same time, the second motor cooperates with the placement plate to drive the optical components to rotate, so as to facilitate the rapid fixation of the optical components.

[0064] The working principle of the present invention is as follows: when in use, firstly, the box door 111 is opened by the handle 1111, and the optical component is placed on the placement plate 1272, and the first motor 121 is started, so that the first motor 121 drives the bidirectional threaded rod 122 to rotate, and the bidirectional threaded rod 122 drives the two groups of connecting rods 123 to move, and the connecting rods 123 drive the two groups of clamping blocks 1232 to move, so that the optical component is clamped by the clamping blocks 1232 for use;

[0065] Specifically, when the clamping block 1232 is clamping the optical component, the L-shaped fixing rod 124 drives the first piston rod 125 to move, and the first piston rod 125 sprays the cleaning liquid inside the first piston cylinder 126 through the outlet pipe 1261, so as to facilitate the cleaning of the surface of the optical component and facilitate the subsequent coating of the optical component.

[0066] Furthermore, after the cleaning is completed, the one-way threaded rod 132 is driven to rotate by the third motor 131, and the one-way threaded rod 132 is used to drive the movable plate 134 to descend, and the movable plate 134 is limited by the slide bar 133. After the movable plate 134 descends, the first metal iron sheet 1342 contacts the second metal iron sheet, so that the fan 115 is started through the interaction between the first metal iron sheet 1342 and the second metal iron sheet, and the optical components are dried by the fan 115 in cooperation with the air outlet pipe 1151;

[0067] Furthermore, during the descent process, the movable plate 134 drives the second piston rod 135 to move through the fixed block 1341, thereby cooperating with the second piston cylinder 136 to suck the coating liquid inside the liquid storage box 113 into the second piston cylinder 136. After the optical component is dried, the movable plate 134 drives the optical component to move upward, and the coating liquid inside the second piston cylinder 136 is sprayed onto the surface of the optical component through the nozzle 1361 through the second piston rod 135, thereby performing a coating operation on the optical component. At this time, the first motor 121 cooperates with the bidirectional threaded rod 122 to drive the two groups of clamping blocks 1232 to release the limit on the optical component, and at the same time, through the action of the first piston rod 125, the water inside the water storage tank 112 is sucked into the first piston cylinder 126, so as to facilitate subsequent use;

[0068] To be more specific, after the optical components are coated, the staff starts the ultraviolet lamp 116 to cure the optical components. At the same time, the placement plate 1272 is driven to rotate by the second motor 1271, thereby driving the optical components to rotate through the placement plate 1272, thereby increasing the speed of the optical components during curing and improving work efficiency. After the processing is completed, the box door 111 is opened to take out the optical components.
