Description

Technical Field

[0001] The invention relates to the technical field of automobile glass processing, and in particular to an automatic primer coating production line for triangular glass. Background Art

[0002] Automobile glass usually needs to be bonded with various accessories. Before bonding, an activator and a primer need to be applied on the glass to make the accessories bond more firmly. In the prior art, the activator and the primer are applied separately, and manual handling is required between the two processes, which has a low degree of automation, wastes manpower, and is inefficient. In addition, in the existing production line, the left and right sides of the same glass need to share a set of molds, and the side positioning and clamping cylinders in the mold interfere with the glass. This causes the operator to replace the cylinder in the production line when coating different side glasses. This affects the production efficiency on the one hand, and on the other hand, it cannot realize the automatic coating of the glass. Every time a glass is replaced, the program of the robot needs to be manually retrieved and input.
