Photosensitive adhesive detecting and repairing device

Abstract

The invention relates to the technical field of plate making, in particular to a photosensitive adhesive detecting and repairing device, which comprises an outer casing, a repairing mechanism and a cleaning mechanism. The outer casing is provided with an air chamber and a liquid storage chamber from top to bottom, the lower end of the liquid storage chamber is opened, and the repairing mechanism comprises a dialing tip which is in sliding connection with the liquid storage chamber and the opening. The repairing mechanism also comprises a pushing portion which drives the dialing tip to upwardsmove to enter the liquid storage chamber through pressing. The cleaning mechanism comprises a piston slidingly connected with the air chamber, the piston is fixedly connected with a piston rod, and the piston rod penetrates into the liquid storage chamber and is fixed at the upper end of the tip end. The air chamber communicates with an air passage arranged inside the outer casing, and the position, close to the opening, of the lower end of the air passage is provided with a gas port. The dialing tip is used for trimming a screen, the dialing tip can be retracted into the liquid storage chamber, and the photosensitive adhesive flows out from the opening, so that the repaired portion of the screen can be coated with the photosensitive adhesive for repairing. The device has multiple functions of puncturing, coating and repairing and impurity removal, the problem of repeatedly switching tools during the manual retouching is solved, and the efficiency and quality of the retouching are improved.

Description

technical field [0001] The invention relates to the technical field of plate making, in particular to a photosensitive adhesive detection and repair device. Background technique [0002] In the process of screen plate making, after development and screen printing, the screen plate may have defects and cannot fully meet the quality requirements. There are defects such as too thin film layer, pinholes, impurities in the photosensitive adhesive, and blockage of the mesh at the pattern, so the screen plate needs to be inspected and revised. The existing general method is to place the screen plate on the revision table and expose the defects through lamps; use a fine needle to pierce the blockage of individual mesh holes; for the film layer is too thin and trachoma, use a fine brush dipped in photosensitive glue on the printing surface Apply on the surface; for the impurities contained in the photosensitive adhesive, use a fine needle to fiddle repeatedly and pick them out, and ...

Problems solved by technology

[0003] However, when the workers are editing the plate, the tools in their hands need to be switched repeatedly, and it is not easy to control the amount of photosensitive glue with a brush when applying the photosensitive glue again, resulting in some repaired parts being too thick, so the revision efficiency is low and the quality is not high.
