A mechanical arm and automatic spraying system

Abstract

The invention relates to the technical field of automation equipment, in particular to a mechanical arm and an automatic spraying system. The mechanical arm includes a base, a driving mechanism, a connector and a clamping claw. The driving mechanism is arranged on the base and can drive the clamping claw to move along multiple axes. The claws are connected with the drive mechanism through the connecting piece; specifically, the claws cooperate with the mandrel to push the claws on the fixing base to turn over from the inner wall of the fixing base to the outer wall, and press and fix the clamping claws on the bottom end of the fixing base. The connection structure between the connector and the jaws is easy to disassemble and assemble, and it is easy to replace the jaws; when painting, control the sliding door to close after the transfer box is in place, and then paint, and the painting is completed in the closed painting box, no need Manual entry, spraying dust is small, saving spraying raw materials, reducing waste gas treatment costs, and manually replenishing and transferring the turnover boxes on the first and second holding trays to maintain uninterrupted operation of spraying and improve efficiency.

Description

technical field [0001] The invention relates to the technical field of automation equipment, in particular to a mechanical arm and an automatic spraying system. Background technique [0002] The turnover box is widely used in the field of transportation and storage. During the long-term use of the turnover box, the metal lath and the solder joints between the laths used in various complex environments are prone to rust, which will affect the firmness of the turnover box itself. And the carrying capacity, the service life of a single turnover box is long, resulting in a huge demand for the turnover box, and the structure of the turnover box is required to be firm and stable; the problem of easy rust of the turnover box can be effectively improved by spraying the surface of the turnover box, and the turnover box can be extended. service life.

[0002] The turnover box is widely used in the field of transportation and storage. During the long-term use of the turnover box, the metal lath and the solder joints between the laths used in various complex environments are prone to rust, which will affect the firmness of the turnover box itself. And the carrying capacity, the service life of a single turnover box is long, resulting in a huge demand for the turnover box, and the structure of the turnover box is required to be firm and stable; the problem of easy rust of the turnover box can be effectively improved by spraying the surface of the turnover box, and the turnover box can be extended. service life

[0003] At present, in the process of spraying the surface of the turnover box, the circulation spraying line occupies a large area. Manual loading, reciprocating machine or robot spraying is used, and finally the spraying treatment on the surface of the turnover box is completed by manual unloading. The cost of painting treatment is high. Environmental pollution is high; if a mechanical arm is used instead of manual loading or unloading, it is necessary to use a variety of specifications of claws to assist the robotic arm to deal with turnover boxes of different specifications. The traditional robotic arm and claws are mostly connected by bolts. It is not convenient to disassemble and assemble between the claw and the mechanical arm
