Description

Technical Field

[0001] The utility model discloses an auxiliary device for off-line spraying of a spraying line, belonging to the technical field of automobile spraying manufacturing. Background Art

[0002] The existing off-line spraying transfer method: the forward movement of the workpiece picking device is controlled by a stepping motor. After moving to the chain workpiece picking position, the product hanger is obtained by lifting the lifting cylinder. The workpiece picking device then retreats to the origin position, the lifting cylinder descends, continues to retreat to the spraying position, rises again to pick up the sprayed product hanger. After the sprayed product hanger makes a 180-degree rotation action with a rotary cylinder, the lifting cylinder descends, and the workpiece obtained at the workpiece picking position is placed on the spraying rack. The workpiece picking device advances to the origin and rises, then advances to the workpiece picking position, descends again to place the original sprayed workpiece back on the product single-column trolley, and makes a rotation reset action after returning to the origin, waiting for the next round of repeated actions.

[0003] This method is extremely unstable; firstly, it is difficult for the stepping motor to operate at a high speed and obtain a large torque, and resonance is likely to occur if the control is improper. It is not easy to ensure the accuracy of the forward and backward movement positions. Secondly, due to the push of the piston in the rotary cylinder, air will accumulate inside the cylinder, affecting the working efficiency of the cylinder. It is difficult to grasp the rotation position and speed, thus affecting the rotation accuracy. Often due to the above reasons, there are problems such as inaccurate workpiece picking and damage to other devices. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems that the existing off-line transfer method has an extremely high failure rate, seriously affects the production rhythm, reduces the production efficiency, affects the product quality, and at the same time increases the maintenance cost, and proposes an auxiliary device for off-line spraying of a spraying line.
