[0044] The specific operations are as follows:

[0045] The second motor 402 drives the bidirectional screw 401 to rotate, and then the screw block 403 drives the clamping assembly 6 to move under the action of the thread. The spacing of the clamping assembly 6 can be adjusted according to the width of the bumper. At the same time, the electric push rod 404 can lift the bumper when it needs to be flipped, thereby ensuring that it has enough flipping space.

[0046] like Figure 1-4As shown, a flip assembly 5 is installed on the output end of the electric push rod 404, and the flip assembly 5 includes: a support 501, the support 501 is fixedly connected to the output end of the electric push rod 404; a third motor 502, the third motor 502 is fixed to the back wall of the support 501 by bolts; a rotating disk 503, the rotating disk 503 is fixedly connected to the output shaft of the third motor 502;

[0047] The specific operations are as follows:

[0048] When the other side of the bumper needs to be processed, the third motor 502 drives the rotating disk 503 to rotate, and the rotating disk 503 drives the clamping assembly 6 to flip, so that the other end of the bumper is displayed in front of the staff.

[0049] like Figure 1-4 As shown, a clamping assembly 6 is installed on the rotating disk 503, and the clamping assembly 6 includes: a clamping plate 601, which is welded to one side wall of the rotating disk 503 and is a U-shaped structure; a telescopic column 603, the fixed part of which is fixedly connected to the inner wall of the top end of the clamping plate 601, and the telescopic column 603 has two groups and is symmetrically distributed on both sides of the clamping plate 601; a spring 604, which is welded to the outer side wall of the telescopic column 603; a pressing plate 602, which is fixedly connected to the movable part of the telescopic column 603 On the moving end; magnetic block 606, magnetic block 606 is fixedly connected to one side wall of the pressure plate 602 and forms a T-shaped structure with the pressure plate 602; guide groove 608, guide groove 608 is formed on the inner wall of the clamping plate 601, and the specification of the guide groove 608 is consistent with that of the magnetic block 606; electromagnet 607, electromagnet 607 is fixedly connected to the bottom end of the guide groove 608; induction switch 605, induction switch 605 is installed on the inner bottom wall of the clamping plate, and the induction switch 605 can be one of a photoelectric sensor and a pressure sensor.

[0050] The specific operations are as follows:

[0051] When clamping and fixing the bumper, the worker places it in the clamping plate 601 of the clamping assembly 6. At this time, the induction switch 605 can detect it and control the electromagnet 607 to be energized to adsorb the magnetic block 606. During the adsorption process, the pressure plate 602 is driven to move downward and the telescopic column 603 and the spring 604 are stretched, so that the bumper can be automatically clamped and fixed without manual operation. This not only ensures the stability of the bumper during processing, but also improves the processing efficiency.

[0052] like Figure 1 As shown, two groups of mounting plates are symmetrically welded on both sides of the base 1, and two groups of fixing bolts are symmetrically arranged on the mounting plates. The mounting plates are combined with the fixing bolts to facilitate fixing the device on the workbench.

[0053] The working principle of the solar photovoltaic adjustment device is as follows: the device is fixed on the workbench by the fixing bolts on the mounting plate, the external power supply is turned on, and then the second motor 402 drives the bidirectional screw 401 to rotate, and then the screw block 403 drives the clamping assembly 6 to move under the action of the thread, and the spacing of the clamping assembly 6 can be adjusted according to the width of the bumper. After the adjustment is completed, the staff holds the bumper and places it in the clamping plate 601 of the clamping assembly 6. At this time, the induction switch 605 can be detected, and the electromagnet 607 is energized to adsorb the magnetic block 606, which drives the pressure during the adsorption process. The plate 602 moves downward and the telescopic column 603 and the spring 604 are stretched, so that the bumper can be automatically compressed and fixed without manual operation. This not only ensures the stability of the bumper during processing, but also during the processing, when the other side of the bumper needs to be processed, the third motor 502 drives the rotating disk 503 to rotate, and the rotating disk 503 drives the clamping assembly 6 to flip, so that the other end of the bumper is displayed in front of the staff. At the same time, the first motor 202 can drive the rotating disk 201 to rotate, and then drive the bumper fixed on the rotating disk 201 to rotate horizontally, so as to ensure that the bumper is fully processed.
