Manufacturing of UV flat pasting machine assembly process
In the assembly process UV flat pasting machine of vehicle body, the "glue welding" process that combines the spot welding with "point" and the coating of adhesive (adhesive) for the structure with "surface" is attracting wide attention. While reducing the number of components such as bolts and welding hours, it can realize light-weight and high-strength joint. By reducing welding points, it can also improve the degree of freedom of body design, which is helpful to realize high value-added body manufacturing.
In order to comply with environmental protection regulations and reduce energy consumption, body lightweight is becoming a topic. In order to solve this problem, "composite material", which combines aluminum alloy, magnesium alloy and CFRP (carbon fiber reinforced plastic), is being used more and more widely in Europe and Japan.
As the bonding method of dissimilar materials, people are studying the technology of using the thermal plasticity softened by CFRP after heating and direct bonding by friction heat. However, due to different thermal expansion rates, they are also faced with the problems of strength maintenance in driving environment and corrosion resistance of the joint. At this stage, it is considered effective to achieve light weight by coating high-strength structure with adhesive and a few bolts.
When the glass is installed on the vehicle body, the dispenser manipulator will be used for automatic coating of sealing materials (sealant and primer). However, if there are defects in the coating of sealing materials, it will lead to water in the body and reduce the corrosion resistance.
Ensure that the UV flat pasting machine sealing material on the whole surface is continuous and the slit coating shape (height, width and volume) is accurate. In order to prevent the outflow of defective products, tracking the coating shape of automatic coating and real-time measurement are also essential.
