Description

Technical Field

[0001] This utility model belongs to the field of automatic spraying technology, and in particular relates to a multi-station automatic constant temperature spraying device. Background Technology

[0002] Automated spraying is a technology that uses automated equipment to replace manual spraying operations. Its core is to use robotic arms or reciprocating machines to carry spray guns and spray primer and topcoat onto the product surface according to a preset program. This technology is widely used in the automotive, home appliance, and furniture industries to improve coating uniformity, material utilization, and production efficiency.

[0003] In some spraying equipment, multiple processes such as spraying and curing are usually carried out intermittently on different equipment or workstations. Workpieces need to be frequently transferred and unloaded, resulting in long production lines, large floor space, and low overall efficiency. At the same time, some spraying equipment uses rigid mechanical clamps to fix workpieces, which can easily cause damage such as indentations and scratches to precision or surface-treated workpieces due to pressure concentration or friction during high-speed automated operation.

[0004] In view of this, we propose a multi-station automatic constant temperature spraying device. Utility Model Content
