[0017] 1. In the metal bracket welding robot with protective components, when welding the metal bracket, sparks and spatters will be generated, which may fly out of the welding area and pose a safety threat to the surrounding environment and operators. The sparks and spatters generated during the welding process may cause pollution to the surrounding environment or damage the equipment. The protective components are used to enclose the area of ​​welding sparks and spatters to prevent them from causing damage to the surrounding environment, thereby reducing the risk of accidents and injuries.

[0018] 2. In the metal bracket welding robot with a protective component, when welding the metal bracket, the metal bracket can be fixed by the fixing component to prevent the metal bracket from shaking during the welding process, thereby causing the welding failure of the metal bracket. The fixing component can accurately and firmly fix the metal bracket in a safe position to avoid safety risks caused by the movement or tilting of the metal bracket during the welding process, which is of great significance for reducing work-related accidents.

[0019] 3. In the metal bracket welding robot with protective components, dust will appear when welding the metal bracket. The dust collection component can effectively absorb the dust generated during the welding process and reduce its dispersion in the air, thereby greatly improving the air quality of the surrounding environment. This is especially important for the respiratory health of employees and can reduce respiratory diseases caused by inhaling dust. The dust collection component can also prevent dust from accumulating on the mechanical parts of the welding robot and reduce the frequency of wear and failure. This not only helps to maintain the normal operation of the equipment, but also extends the service life of the equipment and reduces maintenance and replacement costs.

[0038] Example 2

[0039] Please refer to Figure 1 , Figure 2 and Fig.10 The fixing assembly 300 includes an electric telescopic rod 301, which is fixedly mounted on the rear side of the inner cavity of the placement plate 204. A first tooth plate 302 is fixedly mounted on the left side of the front side of the electric telescopic rod 301, and a gear 303 is meshed on the left side of the first tooth plate 302.

The dust is quickly collected by the collection box 402 to prevent the dust from floating in the air and reduce its dispersion in the air, thereby greatly improving the air quality of the surrounding environment.

[0044] In summary, the working principle of this solution is as follows: the metal bracket to be processed is placed on the two placement plates 204, and the electric telescopic rod 301 is started. When the electric telescopic rod 301 is started, the first tooth plate 302 is driven to move, and when the first tooth plate 302 moves, the gear 303 is driven to rotate, and when the gear 303 rotates, the second tooth plate 305 is driven to move, and when the first tooth plate 302 and the second tooth plate 305 move, the two baffles 306 are driven to move, and the movement of the baffle 306 drives the clamping plate 307 to move, and the two clamping plates 307 are brought close to each other to fix the metal bracket to prevent the metal bracket from being welded. When shaking occurs, the motor 201 is started. When in use, the motor 201 drives the bidirectional screw rod 202 to rotate. The rotation of the bidirectional screw rod 202 causes the two fixed blocks 203 to move. The movement of the fixed block 203 drives the placement plate 204 to move, so that the placement plate 204 is close to the welding robot body 105. The welding robot body 105 can weld the nearby metal bracket. The bidirectional screw rod 202 drives the fixed block 203 to move and drives the first synchronous wheel 206 to rotate. When the first synchronous wheel 206 rotates, it drives the second synchronous wheel 208 to rotate through the belt 207. When the second synchronous wheel 208 rotates, it drives the bidirectional threaded rod 2 09 is rotated, and when the bidirectional threaded rod 209 rotates, the two threaded sleeves 210 are driven to move, and when the threaded sleeve 210 moves, the first inclined block 211 is driven to move, and when the first inclined block 211 moves, it pushes the second inclined block 212 to move toward the top, and when the second inclined block 212 moves, it drives the connecting plate 213 to move, and the connecting plate 213 stretches the spring 215 when it moves, and when the connecting plate 213 moves, it also drives the two second protective plates 214 to move, and fits the two sides of the second protective plate 214 with the two first protective plates 205, and the two first protective plates 205 and the two second protective plates 214 are used in coordination, so as to surround the welding The spark and spatter area is prevented from causing harm to the surrounding environment, reducing the risk of accidents and injuries. When the welding is completed, the metal bracket needs to be taken out by reversing the operation. Dust will be generated when the metal bracket is welded. By starting the fan 405, the fan 405 will absorb the dust generated during welding into the inner cavity of the collection box 402 through the connecting pipe 406 and the dust suction pipe 407 when in use, and then the dust will be blocked inside the collection box 402 through the filter 404. The dust is quickly collected by the collection box 402 to prevent the dust from floating in the air and reduce its dispersion in the air, thereby greatly improving the air quality of the surrounding environment.
