Description

Technical Field

[0001] This utility model relates to the field of optical lens technology, and in particular to an optical lens coating evaporation device. Background Technology

[0002] Optical lenses can refract, reflect, and transmit light to achieve functions such as imaging, focusing, and beam splitting. By heating the evaporation source, the coating material is evaporated into gaseous atoms or molecules. These gaseous particles are deposited and condensed on the lens surface to form a uniform thin film, thereby improving the optical performance of the optical lens.

[0003] Chinese Patent Publication No. CN222082880U discloses a utility model for optical lens coating evaporation fixture, including a substrate. A driven gear is rotatably connected to the top surface of the substrate. Several fixing holes are opened on the top surface of the driven gear. A bottom cylinder is fixedly sleeved on the inner circular wall of the fixing holes. By cooperating with the bottom cylinder, support plate, connecting rod, mounting frame, movable plate, fixing frame, spring, snap-fit ​​post and connecting hole, the support plate can be moved and its position can be determined. By cooperating with the bottom cylinder, rubber soft plate, electric push rod and support plate, the rubber soft plate can fit with the curvature of the optical lens. The further the operator moves the support plate, the greater the curvature that the rubber soft plate can bend, thus adapting to and clamping optical lenses with larger curvatures, and vice versa, achieving the clamping effect of optical lenses with different curvatures, which is convenient for operators to coat optical lenses.

[0004] However, during the optical lens coating process, the bottom barrel is constantly exposed to coating liquid vapor. This vapor may condense and remain on the inner wall of the bottom barrel. At the same time, with the increase of use, the residual coating liquid will gradually accumulate, forming stubborn dirt, which further increases the difficulty of cleaning. Utility Model Content

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0029] According to one embodiment of the present invention, in conjunction with Figure 1 As shown.

[0030] An optical lens coating evaporation device includes: a base plate 1, and a worktable 2 disposed on the upper surface of the base plate 1. A housing 3 is disposed on the upper surface of the worktable 2. A cylinder 4 is disposed above the worktable 2. A clamping assembly 5 for clamping optical lenses is disposed inside the cylinder 4. A coating assembly 6 for steam heating is disposed on the upper surface of the base plate 1. A cleaning assembly 7 for facilitating cleaning of the inner wall of the cylinder 4 is disposed inside the cylinder 4.

[0031] In this embodiment, please refer to Figures 1-5 The cleaning assembly 7 includes a rotating roller 71 rotatably connected to the upper surface of the workbench 2, and a placement tray 72 sleeved on the outer surface of the rotating roller 71. The upper surface of the placement tray 72 is connected to the bottom of the cylinder 4. A first electric push rod 73 is provided on the upper surface of the placement tray 72. An annular cleaning brush 74 is provided at the telescopic end of the first electric push rod 73. The outer surface of the annular cleaning brush 74 contacts the inner wall of the cylinder 4. A fan 75 is provided above the cylinder 4. A connecting cylinder 76 is provided on the upper surface of the fan 75. A connecting ring 77 is sleeved on the outer surface of the rotating roller 71. A connecting rod 78 is provided between the connecting cylinder 76 and the connecting ring 77. The first electric push rod 73... The telescopic movement of the annular cleaning brush 74 up and down cleans the inner wall of the cylinder 4, removing residual dirt from the coating solution vapor adhering to the inner wall of the cylinder 4. Then, the blower 75 is turned on to generate airflow, which blows away the dirt brushed off by the annular cleaning brush 74 in time, preventing the dirt from re-adhering to the inner wall of the cylinder 4. It also helps to quickly dry the cleaned inner wall of the cylinder 4. In addition, although not clearly shown in the figure, the annular cleaning brush 74 is concave in design. Therefore, during the coating process, the annular cleaning brush 74 can wrap around the outer surface of the first electric push rod 73, preventing the coating solution from contacting the first electric push rod 73.

[0032] A motor 8 is installed at the bottom of the worktable 2. A rotating shaft 81 is installed at the output end of the motor 8. The upper end of the rotating shaft 81 extends through the top of the worktable 2. Synchronous pulleys 82 are fitted on the outer surfaces of the rotating shaft 81 and the rotating roller 71. A synchronous belt 83 is fitted between the two sets of synchronous pulleys 82. The motor 8 drives the synchronous pulleys 82 to rotate through the rotating shaft 81 at the output end. The synchronous pulleys 82 drive the rotating roller 71 to rotate through the synchronous belt 83, thereby realizing the rotation of the placement tray 72, which facilitates the loading and unloading of optical lenses.

[0033] A circular groove 721 is provided on the upper surface of the placement tray 72, and a flow equalization plate 722 is provided inside the circular groove 721. The position of the circular groove 721 corresponds to the position of the cylinder 4. The flow equalization plate 722 can improve the quality and uniformity of the coating and reduce coating defects caused by uneven steam distribution.

[0034] The inner walls of the cylinder 4, the annular cleaning brush 74, and the flow equalization plate 722 are all provided with anti-corrosion coatings. The anti-corrosion coatings are made of polytetrafluoroethylene components, which reduce the corrosion of them by the coating solution and thus extend their service life.

[0035] The clamping assembly 5 includes fixed plates 51 symmetrically arranged on both sides of the cylinder 4, and a second electric push rod 52 fixedly installed on one side of each fixed plate 51. Each set of second electric push rods 52 is provided with a silicone clamping plate 53 at its telescopic end. The second electric push rod 52 pushes the silicone clamping plate 53 to move, thereby clamping the optical lens and facilitating the coating operation.

[0036] The coating assembly 6 includes a liquid storage tank 61 disposed on the upper surface of the base plate 1, and a steam heater 62 disposed inside the liquid storage tank 61. A connecting pipe 63 is disposed on one side of the liquid storage tank 61, and an air pump 64 is disposed at one end of the connecting pipe 63. An air outlet pipe 65 is disposed at one end of the air pump 64, and the upper end of the air outlet pipe 65 extends through the top of the workbench 2. An inlet pipe 66 is disposed on the outer surface of the liquid storage tank 61, and the inlet pipe 66 is connected to an external liquid replenishment tank. A liquid level sensor 67 is disposed inside the liquid storage tank 61, and a steam heater 62 is disposed on the outer surface of the liquid storage tank 61. The system includes an LCD screen 68, which is connected to a liquid level sensor 67. A steam heater 62 heats the coating solution in the storage tank 61 into steam. An air pump 64 delivers the steam to the outlet pipe 65 via a connecting pipe 63, and then into the cylinder 4 to coat the lens. In addition, the liquid level sensor 67 can monitor the liquid level in the storage tank 61 and transmit the signal to the LCD screen 68, so that the operator can understand the liquid level. Then, it is connected to an external replenishment tank via an access pipe 66 to replenish the coating solution in a timely manner.

[0037] A housing 9 is provided on the upper surface of the housing 3. A vacuum pump 91 is provided inside the housing 9. One end of the vacuum pump 91 extends through the bottom of the housing 3, and the other side of the vacuum pump 91 is connected to the outside. A control panel 92 is provided on one side of the housing 9. The vacuum pump 91 is connected to the control panel 92. A sealing door 31 is hinged to one side of the housing 3. The vacuum pump 91 is controlled by the control panel 92 to extract the air from the housing 3 to form a vacuum environment, which is beneficial for coating. At the same time, the sealing door 31 makes it easy for operators to put in and take out optical lenses.

[0038] Specifically, the optical lens is placed between two sets of silicone clamps 53, and then the silicone clamps 53 are moved by the second electric push rod 52, thereby clamping the optical lens. Figure 1 As can be seen, the cylinder 4 is equipped with four sets, so four sets of optical lenses can be placed simultaneously for coating. Then, the steam heater 62 is started to heat the coating liquid in the storage tank 61 into steam. The air pump 64 delivers the steam to the outlet pipe 65 through the connecting pipe 63, and then enters the cylinder 4 to coat the lenses. In addition, the liquid level sensor 67 can monitor the liquid level in the storage tank 61 and transmit the signal to the LCD screen 68, so that the operator can understand the liquid level. Then, it is connected to the external replenishment tank through the access pipe 66 so that the coating liquid can be replenished in time. At the same time, the flow equalization plate 722 set inside the placement tray 72 can improve the quality and uniformity of the coating and reduce coating defects caused by uneven steam distribution. In addition, the vacuum pump 91 can be controlled by the control panel 92 to extract the air in the housing 3 to form a vacuum environment, which is beneficial to the coating. Meanwhile, the sealing door 31 makes it easy for the operator to put in and take out the optical lenses. Finally, the extension and retraction of the first electric push rod 73 drives the annular cleaning brush 74 to move up and down, thereby cleaning the inner wall of the cylinder 4 and removing the residual dirt from the coating liquid vapor adhering to the inner wall of the cylinder 4. Then, the fan 75 is turned on to generate airflow, which can blow away the dirt brushed off by the annular cleaning brush 74 in time, preventing the dirt from adhering to the inner wall of the cylinder 4 again, and also helping to quickly dry the cleaned inner wall of the cylinder 4. In addition, although it is not clearly shown in the figure, the annular cleaning brush 74 is designed with a concave shape inside. Therefore, during the coating process, the annular cleaning brush 74 can wrap around the outer surface of the first electric push rod 73, preventing the coating liquid from contacting the first electric push rod 73. Since the inner walls of the cylinder 4, the annular cleaning brush 74 and the flow equalization plate 722 are all provided with an anti-corrosion coating made of polytetrafluoroethylene, the corrosion caused by the coating liquid can be reduced, thereby extending their service life.

[0039] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
