Process tightness of PUR flat pasting machine parts
In order to improve the sealing performance of automotive PUR flat pasting machine engine parts, ECU integrated box, chassis parts packaging and glass body assembly process, we must use liquid gaskets (CIPG, FIPG, etc.), polyurethane foam and other sealing materials (dense agent, bottom agent) coating.
At present, it is a common method to use the manipulator of dispensing machine to carry out slit like automatic coating with sealing material with high aspect ratio along the shape of the workpiece. However, in order to realize high air tightness sealing, continuous and stable sealing material coating must be carried out. The following will introduce the detection solution to realize high-quality automatic coating.
In the assembly process of body solar control glass, water ingress will lead to corrosion and reduction of rigidity on the inner side of the body. Therefore, it is necessary to prevent the outflow of defective coating products of sealing materials (sealing agent and primer).
The "LJ-X8000 series" is introduced into the process of automatic coating of polyurethane foam by using the dispenser manipulator to achieve the overall detection after coating. Ultra high speed sampling with small pitch to detect the cross-section shape after coating and monitor the poor coating.
For objects with large height difference and different PUR flat pasting machine reflection ability, such as curved glass and sealing materials, which are difficult to measure stably, stable measurement can also be realized.
