Technical Field

The invention relates to coating equipment, in particular to an automatic connector-passing coating machine.

Background

When a traditional coating machine meets a base material joint, two solutions of manual knife jumping and automatic knife jumping are mainly adopted. The manual jump cutter judges and operates the start and the end of the jump cutter based on the traveling speed and the position of the base material joint observed by a field operator; the cutter jumping mode is greatly influenced by human factors, and paint waste and waste products caused by cutter jumping cannot be stably controlled. The automatic cutter jumping is based on different sensors and different controller parameter combinations to achieve the starting and ending of automatic control cutter jumping; the cutter jumping mode can avoid the influence of human factors of a site cutter jumping operator, but the difference of the joint angles of the base materials, the difference of the joint heights formed by connecting the base materials with different thicknesses, the range variability of the mechanical production speed and the like can cause problems when the cutter jumping is automatically executed for the parameter combination of a single sensor and a controller; if the combination of parameters of a single sensor and a controller is adopted to achieve universal applicability, the parameters are set to adopt higher jump cutter height and longer jump cutter time, which can cause paint waste and waste products; if multiple sensors and multiple controller parameter combinations are used, it may be possible to more accurately automate the control of the start and end times of the jump blade and the height of the jump blade, but the added sensors and controllers directly reflect on the cost of the equipment. Therefore, there is a need for a structural optimization of such over-substrate joints to overcome the above-mentioned deficiencies.
