Description

Technical Field

[0001] This utility model relates to the field of glass coating technology, and in particular to a coating device for manufacturing optical glass. Background Technology

[0002] Optical glass includes colorless optical glass, colored optical glass, radiation-resistant optical glass, radiation-shielding glass, and optical quartz glass, etc. Optical glass is the foundation and an important component of the optoelectronic technology industry. In practical use, in order to reduce wear and tear on the glass lenses and to meet special usage requirements, optical glass generally needs to be coated.

[0003] By comparing a coating apparatus for manufacturing optical glass with patent publication number CN222250487U, in this scheme, the coating spraying unit is activated, and a compressed air source is provided for the spray gun to spray the coating from the nozzle. Under the horizontal circular motion of the optical glass, a uniform coating is achieved, and excess liquid that does not participate in the coating reaction flows into the water collection tank for centralized discharge treatment, so as not to cause the coating to accumulate on the surface of the optical glass. However, when coating the optical glass, since the optical glass is always in a rotating state, the coating on the surface will be affected by centrifugal force and flung outward. This may reduce the residence time of the coating on the surface of the optical glass and reduce the movement path of the coating on the surface of the optical glass. At this time, it may cause the coating thickness to be different between the center and the periphery of the glass. Utility Model Content

[0004] The purpose of this invention is to provide a coating apparatus for manufacturing optical glass in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A coating apparatus for manufacturing optical glass includes a support base and a coating mechanism for coating optical glass, the coating mechanism being located above the support base.

[0007] The coating mechanism includes a positioning structure for positioning and fixing the optical glass, and a coating structure for coating the optical glass.

[0008] The coating structure includes a support frame mounted above a support base, a lifting plate slidably mounted above the support frame, a downward hydraulic cylinder between the lifting plate and the support frame, a fixed frame fixed at the lower end of the lifting plate, a partition fixed inside the fixed frame, the partition dividing the interior of the fixed frame into two parts, one part being a dust suction chamber and the other part being a blowing chamber, a paint frame fixed at the front end of the fixed frame, and multiple paint tubes at the lower end of the paint frame, a blowing structure inside the blowing chamber for blowing away the paint on the surface of the optical glass, and a cleaning structure inside the dust suction chamber for cleaning dust and impurities on the surface of the optical glass.

[0009] Preferably, the blowing structure includes multiple blower fans located at the upper end of the blowing chamber, multiple air pipes installed at the bottom of the blowing chamber with the bottom ends of the air pipes inclined toward the center of the fixed frame, a sliding plate slidably installed at the bottom of the blowing chamber, multiple through holes opened on the surface of the sliding plate corresponding to the upper ends of the air pipes, a compression spring connecting the sliding plate and the inner wall of the blowing chamber, an arc-shaped plate fixed at the end of the sliding plate away from the dust collection chamber, and an annular wave plate provided below the arc-shaped plate.

[0010] Preferred: The cleaning structure includes multiple vacuum fans set at the upper part of the vacuum chamber, a connecting plate slidably set at the lower part of the vacuum chamber, a cylinder between the connecting plate and the vacuum chamber, a cleaning roller fixed at the lower end of the connecting plate, multiple vacuum holes opened on the surface of the cleaning roller, a filter cartridge inside the cleaning roller, and an exhaust pipe connected between the cleaning roller and the connecting plate.

[0011] Preferred: The positioning structure includes a turntable rotatably set at the center of the support base, a rotating motor installed at the rotating end of the turntable, the output end of the rotating motor being fixed to the rotating end of the turntable via a coupling, multiple suction cups being installed around the center of the upper end of the turntable, a glass body being placed above the suction cups, and a waste bin being fixed to the outside of the turntable.

[0012] Preferably, a baffle is provided above the waste bin, and an annular corrugated plate is fixedly connected to the baffle. The upper part of the baffle is inclined on the side near the center of the turntable.

[0015] Compared with existing technologies, the beneficial effects are as follows:

[0016] The coating mechanism drops paint onto the surface of optical glass. The positioning structure drives the optical glass to rotate, so that the paint is coated on the glass surface. Then, the spraying structure disperses the droplets of paint and blows the dispersed paint towards the center of the turntable. This reduces the amount of paint thrown outward due to centrifugal force, thereby increasing the residence time of the paint on the optical glass surface and increasing the coating path. This allows the paint to be coated repeatedly on the optical glass surface, thus improving the uniformity of the coating. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figures 1-5 As shown, a coating apparatus for manufacturing optical glass includes a support base 100 and a coating mechanism for coating optical glass, the coating mechanism being located above the support base 100.

[0028] In this embodiment, the coating mechanism includes a positioning structure for positioning and fixing the optical glass and a coating structure for coating the optical glass.

[0029] The positioning structure includes a turntable 201 rotatably mounted on the upper end of the support base 100. The inner wall of the turntable 201 is made of rubber. A rotating motor 202 is installed on the rotating end of the turntable 201. The output end of the rotating motor 202 is fixed to the rotating end of the turntable 201 through a coupling. Multiple suction cups 203 are installed around the center of the upper end of the turntable 201. A glass body 204 is placed above the suction cups 203. A waste bin 205 is fixed on the outside of the turntable 201. A baffle 206 is provided above the waste bin 205. The upper end of the baffle 206 is inclined on one side near the center of the turntable 201.

[0030] The coating structure includes a support frame 207 positioned above the turntable 201, which is fixedly connected to the support base 100. A lifting plate 209 is slidably mounted above the support frame 207. A downward hydraulic cylinder 208 is provided between the lifting plate 209 and the support frame 207. A fixed frame 210 is fixed to the lower end of the lifting plate 209. A partition is fixed inside the fixed frame 210, which divides the interior of the fixed frame 210 into two parts: a dust suction chamber 211 and a blowing chamber 218. A paint frame 225 is fixed to the front end of the fixed frame 210. Multiple paint tubes 226 are provided at the lower end of the paint frame 225. The blowing chamber 218 has a blowing structure for blowing away the paint on the surface of the optical glass. The dust suction chamber 211 has a cleaning structure for cleaning dust and impurities on the surface of the optical glass.

[0031] The blowing structure includes multiple blower fans 219 disposed at the upper end of the blowing chamber 218. A sliding plate 220 is slidably installed at the bottom end of the blowing chamber 218. Multiple air blowing pipes 222 are installed at the bottom end of the blowing chamber 218. The bottom ends of the air blowing pipes 222 are inclined toward the center of the fixed frame 210. Multiple through holes 221 are opened on the surface of the sliding plate 220. The through holes 221 correspond to the upper ends of the air blowing pipes 222. A compression spring is connected between the sliding plate 220 and the inner wall of the blowing chamber 218. An arc-shaped plate 223 is fixed at the end of the sliding plate 220 away from the dust collection chamber 211. An annular wave plate 224 is provided at the upper end of the baffle 206. The annular wave plate 224 and the arc-shaped plate 223 are both smooth on the side closest to each other.

[0032] The cleaning structure includes multiple suction fans 212 located at the upper part of the suction chamber 211. A connecting plate 214 is slidably arranged at the lower part of the suction chamber 211. A cylinder 213 is provided between the connecting plate 214 and the suction chamber 211. A cleaning roller 215 is fixed at the lower end of the connecting plate 214. The surface of the cleaning roller 215 is made of foam material and has multiple suction holes. A filter cartridge 216 is provided inside the cleaning roller 215. An exhaust pipe 217 is connected between the cleaning roller 215 and the connecting plate 214. The coating mechanism drips paint onto the surface of the optical glass. The rotation of the turntable 201 drives the optical glass to rotate, so that the paint is coated on the glass surface. Then, the spraying structure blows the droplet paint away and blows the sprayed paint towards the center of the turntable 201, reducing the paint from being thrown outward due to centrifugal force. This increases the residence time of the paint on the surface of the optical glass, increases the coating path of the paint, and enables the paint to be coated repeatedly on the surface of the optical glass, thereby improving the uniformity of the coating.

[0033] Working principle: First, the glass body 204 is placed above the suction cups 203. Multiple suction cups 203 are used to adhere and fix the glass body 204. Then, the rotating motor 202 is started to rotate the turntable 201, causing the fixed glass body 204 to rotate. Next, the downward hydraulic cylinder 208 is driven to move the lifting plate 209 downward, causing the fixing frame 210 to move downward. Then, the cylinder 213 is driven to move the connecting plate 214 downward, causing the cleaning roller 215 to move downward until it is in contact with the surface of the glass body 204. While the glass body 204 rotates, the cleaning roller 215 cleans the dust and other impurities on the surface of the glass body 204. Then, multiple vacuum fans 212 are activated to create negative pressure inside the vacuum chamber 211. The dust and other impurities are drawn into the cleaning roller 215 through multiple suction holes on the surface of the cleaning roller 215. The filter cartridge 216 inside the cleaning roller 215 filters these impurities. After cleaning the surface of the glass body 204, the cleaning roller 215 is moved upward and detached from the surface of the glass body 204.

[0034] Then, paint is dripped onto the surface of the glass body 204 using the paint frame 225 and paint tube 226. The rotation of the glass body 204 itself coats the surface with paint. Paint thrown outwards is blocked by the baffle 206 and finally falls into the waste bin 205 for recycling. Then, multiple fans 219 are activated. As the turntable 201 rotates, it drives the annular wave plate 224 above the baffle 206 to rotate. The annular wave plate 224 and the arc plate 223 squeeze each other, causing the arc plate 223 to drive the sliding plate 2. The 20 reciprocates to adjust the air inlet diameter of the through hole 221, thereby increasing the blowing pressure of the air blowing pipe 222. Multiple air blowing pipes 222 blow air onto the surface of the glass body 204, dispersing the coating on the surface of the glass body 204. Then, the dispersed coating is blown toward the center of the turntable 201, reducing the coating from being thrown outward due to centrifugal force. This increases the residence time of the coating on the optical glass surface, increases the coating path, and enables the coating to be applied reciprocally on the optical glass surface, thereby improving the uniformity of the coating.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
