Automatic gluing device

Abstract

The invention discloses an automatic gluing device. A vacuum adsorption table, a glue discharging needle tube, a glue scraping scraper plate and a control device are included. The upper end face of the vacuum adsorption table serves as a work plane for adsorbing a to-be-glued workpiece. The glue discharging needle tube horizontally moves along a horizontal control guide rail arranged on the work plane and is used for spot coating of an adhesion agent to the to-be-glued workpiece adsorbed to the work plane. The glue scraping scraper plate horizontally moves along the horizontal control guide rail and is used for scraping the adhesion agent arranged on the surface of the to-be-glued workpiece in a spot coating manner to be even and flat. The control device is connected with the vacuum adsorption table, the glue discharging needle tube, the glue scraping scraper plate and the horizontal control guide rail and controls the motions of the vacuum adsorption table, the glue discharging needletube, the glue scraping scraper plate and the horizontal control guide rail. According to the device, adsorption is utilized for achieving to-be-glued workpiece fixing, the to-be-glued surface is completely in the flat work plane, a machine is used for replacing manual work to finish spot coating and slicking, the position and the glue amount of each-time spot coating can be guaranteed, it can beguaranteed that the pressure and the speed of the glue scraping scraper plate relative to the to-be-glued workpiece are fixed, uniform gluing is finally achieved, and the gluing quality is improved.

Description

technical field [0001] The invention relates to the field of aerospace manufacturing and processing, in particular to an automatic gluing device. Background technique [0002] Many sticky products are often coated with adhesive on one side, and the product is pasted on a designated place through the adhesive during use, such as a heating sheet. The heating sheet is an important part of the active thermal control of aerospace products. The heating sheet is pasted on the product that needs temperature control through an adhesive, and the quality of the paste directly affects the temperature control accuracy of the thermal control, which in turn affects the temperature of the entire spacecraft. reliability. [0003] At present, the conventional heating plate glue is applied manually, that is, the operator first dispenses glue manually, and then scrapes the glue with a scraper. This method has the following defects: 1. The thickness of the heating plate glue is uncontrollable, ...

Problems solved by technology

[0003] At present, the conventional heating plate glue is applied manually, that is, the operator first dispenses glue manually, and then scrapes the glue with a scraper. This method has the following defects: 1. The thickness of the heating plate glue is uncontrollable, too Thinness affects the adhesion, and too thick affects the heating effect of the heating sheet; 2. When the heating sheet is not evenly coated, it is easy to produce cavities, and it is easy to burn the heating sheet during the vacuum heating process; 3. Due to different operations by different personnel, multiple heating The consistency of sheet coating is poor, which affects the thermal control temperature control
