Description

Technical Field

[0001] The utility model relates to the technical field of lens screen printing, in particular to a dust removal device for lens screen printing. Background Art

[0002] Screen printing refers to using a screen as a base plate and making a screen printing plate with images and texts through a photosensitive platemaking method. Screen printing consists of five major elements: screen printing plate, scraper, ink, printing table, and substrate. During the processing of items such as cloth, film, and paper, a large amount of dust is usually generated because it is difficult to achieve an absolutely dust-free production environment. The base film absorbs a large amount of dust in the air. The dust removal device for lens screen printing is used to clean the surface of lens printing products before printing to improve product quality and reduce scrap rate;

[0003] Prior art CN201822002977.3, a cleaning device for screen printing of optical lenses, which places the optical lens in an optical lens placement groove, and then drives the first ball screw to rotate through a first motor, and the first screw nut on the first ball screw drives the sliding table and the optical lens to move toward one side of the screen printing machine body through the first nut seat. When the optical lens moves to the lower end of the air blowing pipe port, the air compressor is turned on, and the compressed air is blown out through the air blowing pipe by the air compressor. At the same time, the transverse ball screw mechanism is turned on, and the second motor drives the second ball screw to rotate, and the second screw nut installed on the second ball screw drives the suspension plate and the air blowing pipe installed at the bottom of the suspension plate to move transversely, thereby realizing continuous soot blowing of the optical lens. After soot blowing, the optical lens directly enters the screen printing machine body for printing under the drive of the longitudinal ball screw mechanism.

[0004] However, in the process of dust removal by blowing compressed air on the lens, dust is easily scattered everywhere, which makes it easy for dust to stick to other cleaned lenses. In addition, due to the different thicknesses of some lenses, it is difficult to grasp the distance between the dust removal device and the lens, thus affecting the dust removal effect. Therefore, it does not meet the existing needs. We propose a dust removal device for screen printing of lenses. Utility Model Content

[0020] A bidirectional threaded rod 403 is connected between the fixed plates 401 on both sides through the drive of the second motor 402, and a sliding rod 404 is fixedly connected on both sides of the bidirectional threaded rod 403 and between the two fixed plates 401, and two limit plates 405 are threadedly connected to the two sides of the outer surface of the bidirectional threaded rod 403, and the two ends of the limit plates 405 are respectively slidably connected to the outer surfaces of the two sliding rods 404.

[0021] When the lens moves between the two limit plates 405, the second motor 402 is started to drive the bidirectional threaded rod 403 to rotate. While the bidirectional threaded rod 403 rotates, the threads drive the limit plates 405 on both sides to approach each other along the sliding rod 404, so that the lens can be clamped and corrected between the two limit plates 405 to prevent the lens from being placed crookedly and affecting dust removal.

[0022] The adjustment structure 7 includes a support plate 701 and a roller 705. The support plate 701 is fixedly arranged on the front and rear sides of the conveying frame 1. A movable groove 702 is opened inside the two support plates 701 near the upper end. The movable plate 703 is slidably connected inside the movable groove 702.
