Description

Technical Field

[0001] The invention relates to the technical field of optical lens manufacturing, and in particular to a continuous optical lens coating device. Background Art

[0002] In the prior art, optical lenses are made by mixing high-purity oxides of silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc. according to a specific formula. The specific production process is as follows: first, these materials need to be melted into liquid materials at high temperature, and then these liquid materials are stirred evenly through a stirring device, and attention is paid to removing the chess and card tissues, etc.; then, the melted and evenly stirred materials are placed into the mold through the optical lens mold device, and after waiting for cooling, the optical lens blank is formed.

[0003] After that, the blank needs to be polished and ground to make the lens smooth, and then cleaned and dried. Finally, the lens needs to be vapor coated to form a coating layer on the surface of the lens, thus completing the production of the overall optical lens.

[0004] In the above-mentioned overall process, the coating process of the optical lens is a crucial link. The prior art also discloses many devices related to optical lens coating. For example, the technical solution of Publication (Announcement) No.: CN221344680U discloses "an optical lens coating device"; for example, Publication (Announcement) No.: CN220057011U discloses "an optical lens coating fixture".

[0005] The difficulty of the optical lens coating device is that all positions of the optical lens need to be coated, so the coating is difficult. Therefore, there are equipment such as clamps for optical lens coating in the prior art. However, even if there are tools such as clamps for coating in the prior art, there will still be coating blind spots.

[0006] In addition, whether in the above technical solution or the existing technical solution, the coating device is not designed as a continuous structure, but the optical lens is placed in a box during coating, the equipment stops after coating, and the optical lens after coating is taken out, and then the coated lens is placed again. The overall process cannot work continuously, resulting in low work efficiency.

[0007] Therefore, in order to solve the above problems, it is necessary to develop a continuous optical lens coating device with a reasonable structure that can effectively improve the coating efficiency. Summary of the invention

DETAILED DESCRIPTION

[0027] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, a continuous optical lens coating device comprises a coating steam box 1, the coating steam box 1 is arranged as a long strip structure, and the left and right side ends of the coating steam box 1 are arranged as semicircular semicircular profile structures 2, and the semicircular profile structures 2 on both sides are also correspondingly installed with transmission rollers 3, the transmission rollers 3 are arranged cocentrically with the semicircular profile structure 2, and a mesh conveyor belt 4 is correspondingly installed between the transmission rollers 3 on both sides; a transmission gap is reserved between the mesh conveyor belt and the coating steam box 1, and the mesh conveyor belt 4 is driven by the transmission rollers 3 to rotate clockwise in the coating steam box 1;

[0029] A plurality of evenly spaced partitions 5 are also installed on the mesh conveyor belt 4. The partitions 5 are installed in a direction perpendicular to the mesh conveyor belt 4, and the height of the partitions 5 is adapted to the transmission gap size, so that the upper end of the partitions 5 is close to the inner wall of the coating steam box 1, and the partitions 5 on the mesh conveyor belt 4 in the semicircular profile structure 2 on both sides are also close to the inner wall of the semicircular profile structure 2, so that the mesh conveyor belt 4 can drive the partitions 5 to move as a whole in the coating steam box 1;

[0030] An optical lens placement area 6 is formed between adjacent partitions 5, and a feed port 7 is provided just above the semicircular contour structure 2 at the left end, while a discharge port 8 is correspondingly provided just below the semicircular contour structure 2; and a steam nozzle 9 is also installed on the coating steam box 1, and the steam nozzle 9 is connected to a coating steam device 10, through which the steam for coating is sprayed into the coating steam box 1 to coat the optical lenses in the box.

[0031] A transparent installation chamber 11 is arranged in the middle position of the coating steam box 1, and the installation chamber 11 is arranged between the upper and lower mesh conveyor belts 4. The upper side wall of the installation chamber 11 corresponds to the mesh conveyor belt 4 of the upper layer, and the lower side wall of the installation chamber 11 corresponds to the mesh conveyor belt 4 of the lower layer.

[0032] The steam nozzle 9 is fixed on the upper side wall and the lower side wall of the installation chamber 11 respectively. The steam nozzle 9 extends into the coating steam box 1, and is aimed at the upper mesh conveyor belt 4 from the upper position, and corresponds to the lower mesh conveyor belt 4 from the lower position; and under the action of the externally installed coating steam equipment 10, the steam for coating is sprayed from the steam nozzle 9 onto the upper and lower mesh conveyor belts 4.

[0033] The steam spray heads 9 are arranged in two rows on the upper and lower side walls of the installation chamber 11, and each row has six steam spray heads 9 arranged at even intervals.

[0034] The feed port 7 and the discharge port 8 are both provided with end covers 12 through hinged assemblies, and the feed port 7 and the discharge port 8 can be opened and closed by the provided end covers 12; the sizes of the feed port 7 and the discharge port 8 are consistent with the sizes of the placement area 6.

[0035] A driving mechanism 13 is also installed on the outside of the semicircular contour structure 2 at the left and right ends of the coating steam box 1. The main shaft of the driving mechanism 13 is connected to the transmission roller 3. The transmission roller 3 is driven to rotate by the driving mechanism 13, thereby driving the internal mesh conveyor belt 4 to rotate; the driving mechanism 13 is set to a step-by-step drive mode.

[0036] The overall working process of the present invention is as follows: first, the driving mechanism drives the transmission roller at the semicircular profile structure to rotate, thereby driving the mesh conveyor belt to rotate, and the driving mechanism is a step-by-step driving form, so the mesh conveyor belt will gradually bring each placement area to the position below the feed port in turn, and the spacing between the partitions on the mesh conveyor belt is equal, and the size corresponds to the position of the feed port above. When the placement area is located directly below the discharge port, the driving mechanism can be set to stop for 30-60s, and the optical lens to be coated is placed from this position in the placement area below, and the optical lens in the placement area will move with the mesh conveyor belt.

[0037] During the movement, the placement area will pass the semicircular contour structure on the right, and then move to the mesh conveyor belt position on the lower layer. During this movement, the optical lens will fall downward due to gravity. The present invention accordingly sets the height position relationship between the inner wall of the coated steam box and the partition. The optical lens will be blocked by the inner wall of the coated steam box during the overall movement, and will move with the mesh conveyor belt under the push of the baffle until it moves to the unloading port directly below the semicircular contour structure on the left.

[0038] During the overall movement of the above-mentioned optical lens, the installation room located at the middle side of the coating steam box is correspondingly installed with upper and lower coating nozzles, and the coating nozzles are connected to coating steam equipment. The coating nozzles can spray coating steam into the coating steam box and aim at the mesh conveyor belt in the up and down directions. Therefore, the optical lens can be coated accordingly during its movement. The coating steam sprayed upward can achieve coating on the lower end surface of the optical lens. When the optical lens moves to the position of the mesh conveyor belt on the lower layer, the position of the optical lens will be turned over accordingly, and the coating steam on the lower side wall of the installation room will perform steam coating on the optical lens on the lower layer, eliminating the coating dead angle of the optical lens and ensuring that the optical lens is coated as a whole. In the above-mentioned process, the mesh conveyor belt itself is a mesh structure, which will not hinder the flow of steam and has a reasonable structure.

[0039] In the present invention, since the mesh conveyor belt moves continuously, the optical lens can be directly placed into the placement area from the feed port and moved therewith, and then coated during the movement. After that, the coated optical lens moves to the discharge port and falls from the discharge port, thereby realizing continuous coating of the optical lens feeding and discharging.

[0040] In this device, end covers are installed at the positions of the feed port and the discharge port. When in use, the end covers can be covered as a whole, so that the internal optical lens moves back and forth in the coating steam box for several rounds. After ensuring that the optical lens is coated as a whole, the end cover of the discharge port is opened, and the optical lens passing the discharge port position will fall, realizing the discharge process of the optical lens after coating; similarly, after several rounds of coating, the end cover at the feed port can be opened accordingly to realize feeding from the end cover.

[0041] The above specific implementation is only a preferred embodiment of the present invention and is not intended to limit the implementation of the present invention and the scope of the claims. All equivalent changes and modifications made according to the content of the patent protection scope of the present invention should be included in the scope of the patent application of the present invention.
