[0068] Embodiment three:

[0069] The third embodiment is a further optimization of the first embodiment. The side of the clamping plate 34 opposite to the electric push rod two 33 is configured with anti-skid lines. The anti-skid lines take into account the possibility of sliding of the switch cabinet during transportation and screwing on the automatic production line. By increasing the anti-skid lines on the side of the clamping plate 34 that contacts the switch cabinet, the friction between the clamping plate 34 and the switch cabinet can be increased, thereby effectively preventing the switch cabinet from sliding during clamping and ensuring accurate positioning of the switch cabinet during screwing.

[0070] In this scheme, the screwing process of the switch cabinet assembled industrial robot is an efficient, accurate and automated operation process, and the specific steps are as follows:

[0071] I. The switch cabinet is first placed on the transportation belt 22 of the transportation belt assembly 2. The transportation belt 22 is supported by a plurality of rotating rollers 21 and driven by a servo motor one 24 to ensure smooth movement of the switch cabinet along the production line.

[0072] II. When the switch cabinet reaches the predetermined position, the clamping and fixing mechanism 3 starts to work. The two clamping pieces move to the two sides of the switch cabinet along the mounting frame 11. The electric push rod one 32 and the electric push rod two 33 work together to make the clamping plate 34 clamp the switch cabinet, ensuring the stability of the switch cabinet during screwing.

[0073] III. The screwing mechanism 4 is adjusted to a position suitable for the height of the switch cabinet by the lifting assembly 42. The screwing assembly 43 is finely adjusted by the adjusting piece 44 and the driving assembly 45 to ensure that the screwdrivers 434 of the four screwing parts are accurately aligned with the screw holes on the switch cabinet.

[0074] IV. The servo motor six 458 drives the driving rod 453, which synchronously drives the four device rods 433 through the connecting wheel three 455 and the connecting belt three 456, so that the four screwdrivers 434 start to rotate at the same time to perform the screwing operation. This synchronous operation ensures that all screws are tightened with the same force and speed, improving the consistency and reliability of screwing.

[0075] V. After the screwing of one side is completed, the electric push rod 32 lifts the clamping plate 34, so that the power distribution cabinet is lifted to a certain height, the servo motor 331 drives the clamping plate 34 to rotate, so that the power distribution cabinet is turned over, and the side which has not been screwed is upward, then the electric push rod 32 controls the clamping plate 34 to descend, and the power distribution cabinet is stably placed back on the conveying belt 22, and the screwing operation of the other side is prepared;

[0076] VI. Steps IV and V are repeated to screw the screw holes on the other side of the power distribution cabinet;

[0077] VII. After the screw holes on the four sides of the power distribution cabinet are screwed, the electric push rod 33 releases the clamping, the power distribution cabinet is released and continues to move forward along the conveying belt 22 to enter the next production link.

[0078] It should be particularly pointed out that the specific model specifications of the servo motor 24, the electric push rod 32, the electric push rod 33, the servo motor 331, the servo motor 354, the electric push rod 421, the servo motor 4313, the servo motor 444, and the servo motor 458 need to be determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the art, so it will not be described in detail, and the principles of these components are clear to those skilled in the art, and will not be described in detail here.

[0079] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
