Glue scraping device for electronic touch screen

Abstract

The invention discloses a glue scraping device for an electronic touch screen. The glue scraping device for the electronic touch screen comprises an annular frame type guide rail assembly, a scraper, a first synchronous tooth belt and a bladeless fan. A guide column is arranged at one end of the scraper and is in guide connection with the annular frame type guide rail assembly. A stress groove is formed in the annular surface of the guide column in a concave manner. First synchronous teeth are arranged on the inner surface of the first synchronous tooth belt and used for abutting against the interior of the stress groove. The bladeless fan is used for sucking and removing excessive glue scraped from the upper surface of a touch screen body through the scraper. The air outlet side of the bladeless fan faces away from one side of a supporting plate. According to the glue scraping device for the electronic touch screen, cold scraping is conducted on the excessive glue formed around the touch screen after the touch screen is bonded, the scraped residual glue is collected in an air suction manner in a unified manner, the structure is simple, and the work efficiency is high.

Description

technical field [0001] The invention relates to the technical field of electronic equipment processing, in particular to an electronic touch screen scraping device. Background technique [0002] The touch screen needs to be glued during the processing process, so that the two pieces of glass are bonded or the glass is bonded to the substrate, and the compression after the glue is used to cause the problem of colloidal bonding, but in the process of compression, the colloid between the two pieces of glass It will overflow, therefore, it is necessary to arrange corresponding personnel on the production line to scrape the overflowing glue. [0003] The existing published patent title is "A Method for Producing Squeegee for Electronic Touch Screen" and the publication number is CN108405280A. This patent has the following technical problems: [0004] 1. The base is located in the middle of the square frame. Guide rails are fixed on the upper surface of the four sides of the squa...

Problems solved by technology

[0004] 1. The base is located in the middle of the square frame. Guide rails are fixed on the upper surface of the four sides of the square frame. Each guide rail is equipped with a scraping structure. The scraping structure includes: blades, electric trolleys, etc., and one device has 4 groups. The structure of the scraper is too complicated;

[0005] 2. The cutter head of the blade in this patent application can heat the glue, so that the glue softens and is easy to scrape off. In the actual operation process, the heated glue is easy to form a wire between the knife and the touch screen, but it is more difficult to scrape clean , and it is easy to cause damage to the cementation of the touch screen;
