With the continuous updating of painting technology, there have been new breakthroughs in color and texture, and various painting processes are pursuing the effect of beauty, corrosion resistance and wear resistance.

[0003] The continuous robot painting production line uses robot tracking painting, which is difficult to adjust the machine. The size of the spray room needs to include the robot's working area, which has high energy consumption, low painting efficiency, and low painting rate. In the painting operation, in the robot automatic painting, the difficulty of adjusting complex work tracking painting, high requirements for painting commissioning personnel, and large robot tracking working area requirements have always been the pain points of robot painting operations. The existing painting mechanism is used to solve the problem of tracking painting during continuous transportation, and the robot's working area needs to be adjusted according to the painting time of the workpiece. The size of the spray room needs to be added with the distance tracked by the robot, which results in the spray room required for continuous robot tracking painting being larger than the spray room required for fixed robot painting. Moreover, the larger the spray room, the greater the energy consumption, the more complex the painting process, and the longer the required painting time. It is necessary to provide an intelligent camel hump continuous conveying fixed painting system to achieve energy saving and reduce costs.

Under the action of the gravity traction mechanism of the imported storage area (the gravity traction mechanism of the storage area includes a traction trolley, traction track, travel sensor, over-limit sensor, counterweight device, counterweight traction system, and safety protection system), the line body inverted zigzag drag chain forms a U-shaped cache in the storage area.

At the cache entrance, the sensor transmits a pulse signal to the PLC, and the PLC When the number of passes reaches the requirement, the upper limit of the buffer area detects the traction trolley, and the lower limit of the buffer area detects the traction trolley, the PLC controls the hump motor to stop and brake, so that the product to be sprayed stays in front of the painting robot, and the workpiece rotation device starts to run forward and reverse as required to achieve uniform spraying without dead angles.
