[0187] By installing this automatic cleaning machine, batch cleaning of lenses can be achieved without manual intervention, greatly improving the processing effect of optical lenses and providing a reliable guarantee for high-quality lens processing.
[0188] The cleaning process of the automatic lens cleaning machine in this embodiment includes:
[0189] Lens loading: The first lens feeding module transports the lenses to the cleaning module;
[0190] Lens cleaning involves sequentially cleaning the concave and convex surfaces of the lens in the cleaning module. Lens cleaning includes:
[0191] The lens is flipped in the flipping unit 6, where the concave and convex surfaces are flipped. The flipping unit 6 receives the lens with the convex surface facing up from the lens loading process. It first flips the lens so that the concave surface faces up, and then wipes the concave surface. After wiping, the flipping unit 6 clamps the lens and flips it a second time so that the convex surface faces up, and then wipes the convex surface. After wiping, the conveying unit 9 transports the lens to the unloading process.
[0192] Lens feeding: The second lens feeding module feeds the cleaned lenses.
[0193] Further, concave surface wiping: the cleaning transfer module 7 clamps the concave-side up lens and transports it to the wiping unit 8 for concave surface wiping, and then the cleaning transfer module 7 returns the wiped lens to the flipping unit 6.
[0194] Furthermore, convex surface wiping: the transport unit 9 clamps the lens with the convex surface facing up and transports it to the second set of cleaning and transfer modules 7. The second set of cleaning and transfer modules 7 clamps the lens with the convex surface facing up and transports it to the second set of wiping units 8 for convex surface wiping, and then returns to the transport unit 9 for transport.
[0195] Furthermore, a cleaning and dust removal process is set up between lens cleaning and lens unloading:
[0196] The cleaning and dust removal linear module 101 clamps the lens after two cleanings and transports it to the dust removal area. The ultrasonic dust removal module 104, which is set in the dust removal area, performs dust removal. After the dust removal is completed, the lens returns to the transport unit 9 for transport.
[0197] Furthermore, an antistatic ionizing air bar 107 is installed on the incoming side of the cleaning and dust removal linear module 101. This allows for two antistatic treatments on the lenses before and after dust removal, ensuring the effectiveness of the lenses.
[0198] By setting up this automatic cleaning process, batch cleaning of lenses can be achieved without manual intervention, which greatly improves the processing effect of optical lenses and provides a reliable guarantee for high-quality lens processing. At the same time, this processing process can be adapted to different lens cleaning methods and can be used in combination with other processes.
[0199] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
