Problems solved by technology

[0004] The above-mentioned surface adhesive layer coating process has the following obvious defects: first, it is labor-intensive and time-consuming to paste the masking tape, and the consumption of masking tape is large; second, the standard of manually pasting the masking tape is difficult to control, resulting in uneven width of the surface adhesive layer , there is a potential off-network risk
However, there are still certain problems in the above-mentioned solution, that is, it is necessary to manually move the proprietary tool, so that due to the inconsistency of the moving speed of the proprietary tool, it will eventually lead to the inconsistency of the thickness of the mesh surface adhesive layer

Abstract

The invention discloses a tool special for an SMT laser moldboard stretching net coating face glue layer. The tool comprises a tool body with a scraper blade, an abutting mechanism, an angle control mechanism and a glue scraping mechanism; the abutting mechanism comprises a threaded rod, a rotating handle and a sliding support; the angle control mechanism is a crank and rocker mechanism; and the glue scraping mechanism comprises a sliding block and a lead screw. The tool has the beneficial effects that the distance between the bottom end of the scraper blade and a gauze is controllable through the angle control mechanism; meanwhile, the advancing speed of the scraper blade is controllable through the glue scraping mechanism; by means of the above two control devices, the thickness of the face glue layer can be accurately controlled; in this way, utilized materials of resin glue can be saved; and in addition, the gluing effect of the gauze and a screen frame can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of SMT laser templates, in particular to a special tool for SMT laser template stretching and coating surface adhesive layer. Background technique [0002] The net yarn and the net frame in the tensioned state of the SMT laser template are glued and fixed with resin glue, and the adhesive fixation is realized by the primer layer coated on the net frame and the top glue layer coated on the peripheral surface of the net yarn. [0003] In the existing process of coating the surface adhesive layer, in order to prevent the resin glue from sticking to the non-adhesive area of ​​the mesh and the side of the screen frame, it is necessary to manually paste masking tape on the edge of the non-adhesive area of ​​​​the mesh and the side of the screen frame. Peel off the masking tape after the adhesive layer is applied. [0004] The above-mentioned surface adhesive layer coating process has the following obvious defects...
