Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrolytic aluminum technology, specifically to a robotic spraying device for carbon block coating. Background Technology
[0002] In the production of anode carbon blocks, the surface coating process is crucial. Traditional methods mainly involve manual brushing or semi-automatic spraying using handheld spray guns and simple spraying machines. This method has significant drawbacks: 1. Operators need to move between finished anode carbon blocks, resulting in limited working space and a high risk of collisions with heavy objects and moving equipment, posing a significant personal safety risk. Furthermore, manual operation is slow. 2. The stability and consistency of manual operation are difficult to guarantee, leading to uneven coating thickness, affecting product performance and subsequent use. 3. Inaccurate control of spraying trajectory and dosage easily causes paint splattering and over-spraying, resulting in raw material waste and high production costs. 4. The spraying site typically presents harsh environments with high temperatures and pervasive dust, severely impacting worker health and comfort.
[0003] To address the aforementioned issues, we introduced automated spraying technology, specifically: a six-axis industrial robot with a 2025mm reach is used, with the spray nozzle precisely mounted on the robot's end effector; a catenary conveyor system continuously transports the anode carbon blocks; a high-precision (e.g., 2mm accuracy) laser displacement sensor is installed at the spraying station to detect in real time when the anode carbon blocks reach the predetermined position, triggering the catenary system to stop; the robot then automatically sprays the stationary anode carbon blocks according to a preset program. The advantages of this improved solution include: significantly enhanced safety (personnel are kept away from hazardous areas), increased spraying efficiency, and the potential to achieve a more uniform coating.
[0004] However, since the anode carbon blocks are typically hoisted during the overhead conveyor transport process, after stopping at the spraying station, they are only constrained by the suspension points of the overhead conveyor. Under the spraying impact force (airflow and paint spray reaction force) applied by the robot's spray head, the carbon block body (especially the suspended lower part) will still experience significant shaking or swaying. This dynamic instability leads to a relative displacement between the robot's preset static trajectory and the actual shaking surface of the carbon block, resulting in paint splatter, overspray, and ineffective spraying areas. This reduces paint utilization, severely damages the uniformity of coating thickness, and also wastes raw materials.
[0005] Therefore, this application provides a robotic spraying device for carbon block coating to solve the above-mentioned problems. Utility Model Content
[0006] The technical problem this invention aims to solve is to overcome existing defects and provide a robotic spraying device for carbon block coating. By clamping and positioning the bottom of the anode carbon block, it effectively overcomes the core defect of anode carbon block shaking in existing automated spraying solutions, improves the uniformity of coating thickness, and the stable anode carbon block makes the robot's spraying trajectory more accurate. This effectively reduces the phenomenon of paint splashing, overspraying, and ineffective spraying areas caused by anode carbon block shaking, improves paint utilization, saves costs, and is easy to use, thus effectively solving the problems in the background technology.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a carbon block coating robot spraying device, comprising two symmetrically arranged robotic arms, a spraying machine, and a positioning component. The spray nozzle of the spraying machine is mounted on the robotic arm. The positioning component includes a housing, inside which a dual-axis motor is installed. Each output shaft at both ends of the dual-axis motor is provided with a screw. A drive plate is threaded onto the screw. Positioning plates are installed at both ends of the drive plate. A base mounted on the ground is rotatably mounted on the bottom of the positioning plate. A strip-shaped hole is opened in the middle of the side of the positioning plate, and a fixed shaft that movably passes through the strip-shaped hole is provided on the side of the drive plate.
[0008] As a preferred embodiment of this utility model, a bracket is rotatably mounted on the end of the screw away from the housing, and the bottom of the bracket is installed on the ground.
[0009] As a preferred embodiment of this utility model, the drive plate is provided with a guide rod on the side corresponding to the housing, and the housing is provided with a guide ring on the side corresponding to the guide rod, with the guide rod movably inserted inside the guide ring.

The sprayer head of the sprayer 2 is installed on the robotic arm 1. The positioning component includes a housing 3, and a dual-axis motor 4 is installed inside the housing 3.

A strip hole 61 is opened in the middle of the side of the positioning plate 6, and a fixed shaft 51 is provided on the side of the drive plate 5 that is movably inserted into the strip hole 61. The dual-axis motor 4 drives the screw 41 to rotate. When the screw 41 rotates, it controls the drive plate 5 to move. The drive plate 5 drives the positioning plate 6 to rotate around the base 62 through the fixed shaft 51, thereby clamping and fixing the lower side of the anode carbon block with the positioning plate 6.
[0021] Furthermore, a bracket 7 is rotatably mounted on the end of the screw 41 away from the housing 3. The bottom of the bracket 7 is installed on the ground, which serves to provide auxiliary support for the screw 41.

[0026] When using:
[0027] When the anode carbon block is moved to the spraying station, the dual-axis motor 4 is controlled to work. The dual-axis motor 4 drives the screw 41 to rotate. When the screw 41 rotates, the drive plate 5 is controlled to move. The drive plate 5 drives the guide rod 52 to move along the guide ring 31. The drive plate 5 drives the positioning plate 6 to rotate around the base 62 through the fixed shaft 51, so that the positioning plate 6 clamps and fixes the lower side of the anode carbon block.
[0028] Then, robotic arm 1 and sprayer 2 work together. Robotic arm 1 drives the nozzle of sprayer 2 to run along the set trajectory, thereby spraying the anode carbon block.
