Description

Technical Field

[0001] The utility model relates to the technical field of mechanical arm spraying, in particular to a paint spraying mechanical arm which can rotate automatically. Background Art

[0002] The robotic arm is the most widely used automated mechanical device in the field of robotic technology. It can be seen in various fields. With the continuous development of industrial society, the demand for robotic arms continues to increase. The same is true for the paint processing industry. There are a wide variety of paint robotic arms sold on the market with different styles and forms.

[0003] The Chinese patent document with publication number CN211782278U discloses a paint spraying robot arm that can rotate automatically. When the device is in use, the threaded rod is rotated to drive the X-shaped scissor fork frame to shorten. The X-shaped scissor fork frame is shortened and the robot arm and the spray head are stored inside the box through the bottom plate to avoid spray collision during movement. At the same time, the wheels at the bottom of the bottom plate are in contact with the ground for easy movement, making the device easy to carry.

[0004] However, the device still has obvious shortcomings in the paint spraying mechanism:

[0005] The device adopts a single spray head structure. Although it can adjust the angle, it cannot be equipped with multiple types of paint gun heads at the same time. As a result, when spraying different types of paint lines, the original paint gun head needs to be removed and replaced first, which increases the work cost. In addition, replacing the paint gun head too frequently can easily cause wear on the joint of the paint gun head, which can cause paint leakage during the subsequent painting process.
