The existing glue brushing equipment is almost manually brushed with glue, which is low in efficiency, harmful to the operators' health and high in personnel cost. Some use automatic glue spraying equipment to spray glue onto the surfaces of parts to be sprayed with glue through a glue spraying system, but the glue spraying technology is prone to clogging of the spray head, affecting the spray angle and glue discharge angle, and the atomizing cap, spray gun head and glue pipe need to be frequently cleaned, increasing the complexity of equipment maintenance and operation. Since the spray gun is a atomizing process, the spray range is wide, and the fine particles are easily sprayed onto other positions of the workpiece, causing pollution of the workpiece, which requires additional cleaning processes to handle, and the operators are inevitably splashed into the environment and equipment, causing environmental and equipment pollution, which can harm the operators' health to some extent. In addition, since the spray head needs to be frequently cleaned, the glue in the glue barrel and glue pipe cannot be reused, which leads to waste of glue and water, affects the effective use of glue resources, and causes environmental pollution. Some use automatic glue brushing equipment, and the existing automatic glue brushing equipment generally uses a brush to brush, but the adhesion, resilience and extensibility of the brush cannot be controlled, and the amount of glue applied to the workpiece cannot be controlled, causing uneven brushing of each area of the part to be brushed with glue, with some areas having too much glue and some areas having insufficient glue, some areas being wide and some areas being narrow, which makes the amount of glue and the brushing track of the part to be brushed with glue uneven. In addition, the bristles on the outer edge of the brush can easily expand outward, causing uneven edges of the part to be brushed with glue. Furthermore, the adhesion of the brush cannot be controlled, which can cause clogging of the glue discharge port of the glue gun. SUMMARY
