A laser template stretching net coating surface adhesive layer tool

Abstract

The invention discloses an adhesive layer coating tool for a stretched mesh of a laser template. The adhesive layer coating tool comprises a tool body provided with a scraping plate, a rotating mechanism and a sliding mechanism; the rotating mechanism comprises a hinging rod, a connecting rod, a gear, a movable pin and a supporting plate; one end of the connecting rod is hinged to the tool body through the hinging rod, the other end of the connecting rod is provided with a rack which is engaged with the gear, and the connecting rod is movably installed on the supporting plate. The tool body is driven by the transmission between the gear and the rack to rotate to a certain extent, so that the distance between the bottom end of the scraping plate and the mesh is controllable, and accordingly the thickness of the adhesive layer is controllable; therefore, not only can the amount of resin adhesive be saved, but also the cementing effect of the mesh and a mesh frame can be ensured.

Description

[0001] Technical field: [0002] The invention relates to the technical field of SMT laser templates, in particular to a laser template stretching net coating adhesive layer tool. [0003] Background technique: [0004] The net yarn and the net frame in the tense 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. [0005] 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. [0006] The above-mentioned surface adhesive layer coating process has the following obvious defects: first, it...

AI Technical Summary

Problems solved by technology

[0006] The above 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

[0008] Although the above-mentioned special tool can eliminate the process of manually pasting masking tape and significantly improve the production efficiency, in actual operation of the above-mentioned special tool, the distance between the bottom edge of the scraper and the mesh is completely controlled by the operator manually

Manually controlling the distance between the bottom edge of the scraper and the mesh can cause the distance to be too large or too small; if it is too large, the thickness of the glue layer on the mesh surface will be thicker, which is not only wasteful, but may also lead to unqualified products; If it is too small, the thickness of the glue layer on the mesh surface will be scraped too thin by the bottom edge of the scraper, and the mesh and the frame will not be glued and fixed.
