Problems solved by technology

[0004] However, most of the existing primers contain a large amount of organic solvents, and there will be potential health risks for operators due to the volatilization of VOC (volatile organic compounds) during use
At the same time, after applying the existing primer solvent, it is necessary to reserve enough time window for the solvent to fully volatilize and dry before the next process, which will seriously affect the production beat

Embodiment 1-4

[0035] In the present invention, the inventor enumerates 4 specific embodiments, based on figure 1 For the industrial robot shown, the bonding method implemented in Embodiments 1-4 specifically includes the following steps 100-300:

[0036] 100: Use the plasma treatment device 7 to spray plasma respectively on the first surface and / or the second surface to be bonded to each other for surface cleaning. The processing power of the plasma processing device 7 for surface cleaning is 400-1000W, the distance from the first surface and the second surface is 5mm-20mm, and the surface cleaning processing speed is 50mm / s-300mm / s.

[0037] 200: Using the plasma treatment device 7 to spray a plasma coupling agent on the first surface and / or the second surface for surface activation, so as to form a plasma coupling agent with a thickness of 5-100 μm on the first surface and / or the second surface respectively layer; while the surface is activated, the first surface and / or the second surfac...

Abstract

The invention discloses a bonding method for vehicle parts. The bonding method comprises the following steps: (1) respectively spraying plasmas on a first surface and / or a second surface to be bonded with each other for surface cleaning; (2) spraying a plasma coupling agent to the first surface and / or the second surface to perform surface activation, and gluing the first surface and / or the second surface while performing surface activation; and (3) bonding the first surface and the second surface together. The bonding method provided by the invention is a prime coat-free bonding means, and can ensure the bonding reliability of the surfaces of different materials on the premise of not using a solvent type prime coat.

Description

technical field [0001] The invention relates to a bonding method, in particular to a bonding method for automobile parts. Background technique [0002] In recent years, with the rapid development of the automotive field, more and more manufacturers have begun to use adhesives to connect components in the manufacturing process of automobiles, and use this to replace traditional bolts, riveting, Welded connection. For example: At present, some auto parts suppliers have assembled and connected single parts of different materials into assembly parts through adhesives, and a few vehicle manufacturers will also use adhesives to bond and assemble assembly parts to the body. . [0003] In the current prior art, in order to ensure the reliability of the bonding, it is often necessary to prime the bonding surface or the glued surface of the vehicle parts before the adhesive is glued and bonded. The surface energy of the surface or the increase of active functional groups can effect...
