Painting Production Line
Painting Production Line for CETC 38th Research Institute, Hefei Hengli
Hengli Eletek Co., Ltd. is a subsidiary controlled by the 38th Research Institute of China Electronics Technology Group Corporation (CETC). In 2020, Anjia was responsible for the comprehensive scope of work for the entire painting production line at the company's workshop located within the 38th Research Institute. This included design, procurement, fabrication, installation, commissioning, and training. The painting production line is primarily used for the batch painting of small components and aerospace equipment. The spray booths adopt a dry-type structure with top-down air supply and bottom exhaust. The air supply is provided by air conditioning units, with fresh air intake from outside. Air entering the spray booth is filtered to remove dust before being supplied from the top of the booth.
The small components painting production line utilizes a combined manual and automatic spraying mode. It is equipped with 2 sets of six-axis robots, 4 sets of manual air spray guns, 2 sets of automatic air spray guns, and 3 sets of paint mixing systems (1 for primer, 1 for topcoat, and 1 as spare parts), shared between manual and automatic guns. Color changeovers are performed manually via cleaning. The primer and topcoat share the same spray booth. The conveyor system employs an accumulating overhead chain conveyor, arranged in a loop as an overhead suspension structure. It consists of track, chain, switches, dolly sets and hangers, electrical control system, support columns, and auxiliary beams. The load-bearing dolly sets use a three-dolly configuration, comprising a front dolly, a rear dolly, and a load beam. The operating speed ranges from 8 to 12 m/min.
The aerospace equipment painting production line has a maximum pass-through dimension of 1800mm x 3000mm x 2000mm (H x W x L), with a maximum workpiece weight of 200kg. Consequently, the conveyor method for this line is manual handling and the use of small dollys.
