[0002] With the rapid development of the smartphone industry, the quality requirements for the production and packaging of mobile phone camera lenses, as key components, are becoming increasingly stringent. Before packaging, camera lenses easily accumulate dust. If this dust is not cleaned promptly, it will affect the image quality of the lens, thus impacting the overall performance of the mobile phone camera. Currently, most existing mobile phone camera lens packaging equipment only has simple conveying and packaging functions, lacking a dedicated cleaning structure. This prevents effective cleaning of the lenses before packaging, resulting in inconsistent product quality after packaging, increasing subsequent defect and rework rates, and causing resource waste and increased costs. Furthermore, frequent manual intervention in cleaning not only leads to low production efficiency but also increases production costs and labor intensity, making it difficult to meet the needs of large-scale production. Therefore, there is an urgent need to design a packaging device that can effectively clean dust from camera lenses. Utility Model Content

[0031] The lens to be wiped is placed on the front conveyor belt 103, and transported to the end of the front conveyor belt 103 by the drive of the front conveyor belt 103. At this time, the control slide 202 moves the chuck 207 to directly above the lens, and then the vertical cylinder 203 drives the chuck 207 to move downward, and then the dual-axis cylinder 205 clamps the lens with the chuck 207. After clamping, the control slide 202 moves the chuck 207 to directly above the wiping table 105, and places the lens into the circular groove of the wiping table 105 for wiping the lens surface.

[0032] See Figure 5 As shown, a wiping assembly is provided on the other side of the front conveyor belt 103 and the rear conveyor belt 104. The wiping assembly includes a stand 301 fixedly mounted on a support plate 102. A fixed plate 302 is fixedly mounted on the upper end of the stand 301. Two slide rails 303 are vertically fixedly mounted on the fixed plate 302. An L-shaped movable plate 304 is slidably mounted on the two slide rails 303. A first motor 305 is fixedly mounted on the rear side of the fixed plate 302. A pinion 306 is connected to the output shaft of the first motor 305. The pinion 306 is located on the front side of the fixed plate 302. A rack 307 meshes with the pinion 306. The rack 307 is fixedly connected to the movable plate 304. When the first motor 305 drives the pinion 306 to rotate, it can drive the movable plate 304 to move vertically along the slide rails 303 through the meshing relationship between the pinion 306 and the rack 307. A housing 308 is installed on the outside of the movable plate 304.

[0033] A drive shaft 309 is vertically rotatably mounted on a movable plate 304. A cylindrical wiping block 310 is mounted on the lower end of the drive shaft 309, located directly above the wiping table 105. The diameter of the wiping block 310 is the same as the diameter of the lens. A second motor 311 is connected to the top of the drive shaft 309, which can drive the wiping block 310 to rotate. A solution tank 312 is fixedly mounted on a support plate 102, located on one side of the stand 301, and contains cleaning fluid. A hose 313 connects the solution tank 312 and the wiping block 310, through which the cleaning fluid in the solution tank 312 is delivered to the wiping block 310. The first motor 305 drives the movable plate 304 to move downward, so that the wiping block 310 mounted on the movable plate 304 comes into contact with the lens. The second motor 311 can drive the wiping block 310 to rotate, thus wiping the surface of the lens.

[0034] An air duct 314 is vertically fixed to one side of the movable plate 304. The air outlet is located below the air duct 314. A driven shaft 322 is rotatably mounted inside the air duct 314, and a fan wheel 321 is connected to the lower end of the driven shaft 322. An air outlet duct 315 is connected to the air outlet of the air duct 314, and the end of the air outlet duct 315 is located on one side of the wiping block 310. A main bevel gear 316 is installed at the upper end of the drive shaft 309. A first driven bevel gear 317 meshes with one side of the main bevel gear 316, and a drive shaft 318 passes through the center of the first driven bevel gear 317. The first driven bevel gear 317 is located at one end of the drive shaft 318, and a second driven bevel gear 319 is installed at the other end of the drive shaft 318. A driven bevel gear 320 meshes with one side of the second driven bevel gear 319. The bevel gear 320 is mounted on the driven shaft 322. Through the gear linkage structure, after wiping, the moving plate 304 can be slightly moved upwards, and the second motor 311 can be kept rotating continuously, driving the impeller 321 to rotate. The airflow generated by the impeller 321 is guided through the air outlet 315 and blown onto the lens surface to achieve the lens drying process. It should be noted that during wiping and drying operations, the chuck 207 should be moved aside to avoid obstructing the downward movement of the wiping block 310 and the wiping of the lens. After cleaning, the lens can be packaged.

[0035] See Figure 6-7 As shown, a packaging assembly is provided on one side of the cleaning box 101, and the packaging assembly is connected to the end of the rear conveyor belt 104. The packaging assembly includes a frame 401, one side of which is inclined. A take-up drum 402 and two guide rollers 403 are rotatably mounted on the lower end of the frame 401, with the two guide rollers 403 located above the take-up drum 402. A support plate 404 is installed on the inclined surface of the frame 401, and two parallel limiting plates 405 are fixedly installed on the top of the support plate 404, with the limiting plates 405 located below the rear conveyor belt 104. A bracket 413 is fixedly installed on one side of the support plate 404, and a sealing plate 414 is fixedly installed on the bracket 413, with the sealing plate 414 parallel to the support plate 404 and located above the support plate 404.

[0036] Two sets of sealing rollers are installed on the sealing plate 414. Each set of sealing rollers includes two large gears 406 mounted on the upper surface of the sealing plate 414, which mesh with each other. Two sealing wheels 407 are mounted on the lower surface of the sealing plate 414, corresponding to the two large gears 406. A connecting rod 408 connects the sealing wheels 407 and the large gears 406. The two sets of sealing rollers are connected by a chain. A third motor 409 is connected to one of the large gears 406. The third motor 409 can drive the gear to rotate, thereby driving the sealing wheel 407 to rotate. When the sealing wheel 407 rotates, it can continuously feed the packaging film.

[0037] Two heat-sealing blocks 410 are fixedly installed in the middle of the edge-sealing plate 414. The two heat-sealing blocks 410 are installed opposite each other and are located between two sets of edge-sealing rollers. A cutter holder 411 is installed at the lower end of the support plate 404. The cutter holder 411 is perpendicular to the support plate 404 and can move in a direction perpendicular to the support plate 404. A sealing cutter 412 is fixedly installed on the cutter holder 411. The sealing cutter 412 can heat-seal and cut both ends of the plastic film wrapping the lens.

[0038] Specifically, the cutter holder 411 includes two uprights vertically fixed on the support plate 404, with a cutter plate mounted at the top of each upright. A sleeve is provided on the cutter plate, and a corresponding sleeve is provided on the sealing cutter 412, with the sleeve installed within the sleeve. Furthermore, an electric actuator is fixedly mounted on the cutter plate, which can drive the sealing cutter 412 to move in a direction perpendicular to the support plate 404.

[0039] The aforementioned winding drum 402 winds the packaging film, which first passes between two guide rollers 403, and then is limited into a U-shape by two limiting plates 405 at the top of the frame 401. The lens can fall between the two limiting plates 405 and into the middle of the U-shaped packaging film. Next, the two sides of the U-shaped packaging film are folded in half, so that it passes through two sets of sealing rollers 407 and two heat sealing blocks 410. The heat sealing blocks 410 heat seal both sides of the film, and finally the sealing cutter 412 heat seals and cuts both ends of the plastic film wrapping the lens.

[0040] Example: The lens is placed on the front conveyor belt 103. Driven by the front conveyor belt 103, the lens is transported to its end. Then, the lens is clamped by the clamping assembly and placed on the wiping table 105. The first motor 305 drives the moving plate 304 downwards, causing the wiping block 310 on the moving plate 304 to contact the lens and wipe its surface. After the upper surface of the lens is wiped, the lens can be flipped using the flipping chuck 207 to wipe its lower surface. During wiping, a gear linkage structure drives the fan to rotate, drying the lens. After wiping and drying, the lens is clamped by the clamping assembly and placed on the rear conveyor belt 104. The rear conveyor belt 104 transports the lens to the packaging assembly, where it is laminated and cut for packaging.
