Description

Technical Field

[0001] This utility model belongs to the technical field of automated spraying equipment, specifically, it relates to a multi-directional spraying control robotic arm. Background Technology

[0002] In the field of automotive parts manufacturing and processing, the spraying process is a key step in improving the corrosion resistance, aesthetics, and functionality of parts.

[0003] Utility model CN220215429U discloses a spraying robot arm, including a base. A first connecting arm is rotatably connected to the top of the base, a second connecting arm is rotatably connected to the first connecting arm, and a third connecting arm is rotatably connected to the second connecting arm. A nozzle is fixedly connected to one end of the third connecting arm, and a feed pipe is fixedly connected to the nozzle. A protective component corresponding to the nozzle is provided on the third connecting arm, and a mounting plate is fixedly connected to the protective component. A hot air blower is fixedly connected to the side wall of the mounting plate. This utility model, through the protective component, allows the mounting block to move via a cylinder when not in use, thereby moving the protective frame. Two sliders also slide in the center of the limiting groove, limiting and guiding the movement of the protective frame. When the protective frame moves to cover the nozzle, it protects the nozzle from impacts and increases maintenance costs.

[0004] However, the aforementioned patent still has the following problems: the robotic arm can only rotate the parts during use. When dealing with large automotive parts, due to their large size and weight, relying solely on the rotation of the parts themselves makes it difficult to achieve omnidirectional and flexible position adjustment. This necessitates multiple interruptions to the painting process for manual adjustment of the part's position, increasing the labor intensity of workers, extending the painting time, and reducing overall production efficiency. It fails to meet the demands of modern large-scale automotive production for efficient painting. Furthermore, the robotic arm can only move within a limited area, severely restricting its range of motion and making the device inconvenient to use.

[0005] In view of this, this utility model is proposed. Utility Model Content

The fixed pulley 25 provides auxiliary guidance, realizing the movement of the robotic arm base position. The top of the arc-shaped sliding plate 24 has a first threaded groove 26, and the bottom of the robotic arm base 27 has a second threaded groove 28.
