Glue scraping device for flat piece and with controllable gluing shape

Abstract

The invention discloses a glue scraping device for a flat piece and with a controllable gluing shape. The device comprises an inverted U-shaped base and a glue scraping plate, a height difference exists between the lower edges of vertical walls on the two sides of the U-shaped base, a short vertical wall and a long vertical wall are formed, a glue injection hole is formed in the top wall, and theglue scraping plate is located in the U-shaped base and connected with the top wall; and the bonding face of the flat piece faces upwards and abuts against the lower edge of the short vertical wall, one side face of the flat piece abuts against the inner wall face of the long vertical wall, and a gap is formed between the lower edge of the glue scraping plate and the bonding face of the flat platepiece. The glue scraping device disclosed by the invention is convenient to operate, high in efficiency, uniform in thickness and shape of an adhesive after gluing, neat in surface and free of excessive glue overflow, the gluing is integrally formed, the device can be used for directly bonding a metal part or a nonmetal part, and the controllability of a bonding process is improved; and the device has certain universality and is suitable for flat pieces and glue injection guns of different specifications.

Description

technical field [0001] The invention relates to a squeegee device, in particular to a squeegee device for gluing flat parts. Background technique [0002] In the manufacture of aircraft interior parts, there are many metal parts hemming or non-metal parts bonding, and the flat structure interior parts account for a large proportion, such as lockers, kitchen and bathroom, door panels, compartment panels, etc. Metal parts or non-metal parts that are consistent with the outline of the composite parts are bonded to the composite parts. In order to ensure the bonding strength and the overall appearance of the interior parts, the manufacturing requirements need to control the thickness of the adhesive layer to achieve a relatively high interior. Part quality requirements. [0003] Due to the complex shape, large structure and variable bonding position of aircraft interior parts, the automatic squeegee equipment currently on the market is expensive and bulky, which is not convenie...

AI Technical Summary

Problems solved by technology

[0003] Due to the complex shape, large structure and variable bonding position of aircraft interior parts, the automatic squeegee equipment currently on the market is expensive and bulky, which is not convenient for actual production operations. In actual production, manual injection of glue with syringes is currently used , and then use a scraper to manually level the squeegee

The disadvantages of manual operation are: 1. The thickness of the adhesive layer cannot be controlled, and the thickness of the adhesive on the entire bonding surface is uneven; 2. The overall thickness of the interior parts after bonding is inconsistent, which affects the appearance and the flushness of adjacent surfaces Requirements; 3. The operation time is long, the efficiency is low, the amount of glue stored in the syringe is small, and the adhesive needs to be filled and trimmed several times; 4. The specific thickness of the glue layer cannot be reflected
