Scraping device for polyimide constantan foil electric heater

Abstract

The invention discloses a scraping device for a polyimide constantan foil electric heater and belongs to the technical field of photoelectric installation. The invention aims at solving the problems in the prior art that the production efficiency is low, the glue solution thickness cannot be controlled and the glue solution is not uniform. The scraping device disclosed by the invention comprises a bottom table, a pressing device and a scraping structure, wherein the bottom table is of a U-shaped integrated structure and comprises a bottom plate; side walls are arranged on two sides of the bottom plate in the length direction; the bottom plate is of a grooved structure; the scraping structure comprises a scraper and a baffle; the scraping thickness is regulated by the baffle; the pressing device is fixedly arranged at one end of the bottom table, so that a heating plate is fixed; and the scraping structure slides along the side wall of the bottom table so as to realize scraping. According to matching of the fixed pressing plate and the bottom plate, multiple heating plates can be simultaneously pressed, the function of simultaneously scraping the multiple heating plates is realized, and the production efficiency is improved. Moreover, the heating plates are arranged in grooves of the bottom table, the scraping thickness is regulated by the baffle at the front end of the scraper, adjustable glue solution thickness is realized, and the uniformity of the glue solution is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of optoelectronic assembly, and in particular relates to a polyimide constantan foil electric heater scraping device. Background technique [0002] Before the polyimide constantan foil electric heater is pasted and wired, it needs to be scraped with GD414 single-component room temperature vulcanized silicone rubber. The traditional squeegee method is usually to use a scraper to evenly apply the glue on the surface of the heating plate of the electric heater. The squeegee can only squeegee one heating plate at the same time, and the production efficiency is low. In addition, due to artificial uncertainty Sex, uncontrollable glue thickness, uneven glue. In the process documents involving the pasting and wiring of heater chips, in order to ensure the quality of pasting, there are often clear requirements for the thickness of the glue - 30 μm to 50 μm. Therefore, it is necessary to design a squeegee device to ...
