[0075] Working principle and use process of this device: In order to clearly describe the working principle of the present invention, we use Figure 1 To elaborate on the perspective;

[0076] S1. The external robot arm grabs the power distribution cabinet body 101 to be inspected on the conveyor, and drives the threaded rod 202 to rotate through the output end of the servo motor 204, so that the two sets of L-shaped plates 205 are close to each other, and the power distribution cabinet body 101 is clamped and fixed. The bottom wall of the power distribution cabinet body 101 is located on the horizontal plate of the L-shaped plate 205, and the left and right side walls of the power distribution cabinet body 101 are completely blocked by the vertical plate of the L-shaped plate 205, and the cabinet door 102 is exposed. The purpose of this is to make the center of the pin connecting the cabinet door 102 and the center of the rotating rod 401 located on the same vertical plane;

[0077] S2, the second screw rod 406 is driven to rotate by the output end of the second stepper motor 409, so that the second movable plate 408 moves to the right side of the cabinet door 102, and the fourth screw rod 602 is driven to rotate by the output end of the fourth stepper motor 605, so that the lifting plate 604 moves up and down along the outer surface of the fourth guide rod 603, so that the lifting plate 604 moves to the height position that matches the keyhole 103, and the output end of the first electric push rod 606 is extended to make the key 610 move to the left, and then, the output end of the second electric push rod 609 is extended, and the key 610 is inserted into the keyhole 103. Driven by the output end of the second drive motor 608, the cabinet door 102 is opened, and then, the output end of the first drive motor 402 drives the first gear 403 to rotate, so that the second gear 404 and the rotating rod 401 rotate as a whole, thereby driving the bottom frame 405 to rotate ninety degrees counterclockwise, and the cabinet door 102 also rotates ninety degrees outward to be vertical to the power distribution cabinet body 101;

[0078] S3, the vacuum suction cup 713 absorbs the external test paper 714, the output end of the fourth electric push rod 703 extends to drive the connecting piece 706 to move upward, and the output end of the third drive motor 701 drives the first drive wheel 702 to rotate, thereby driving the connecting piece 706 to rotate ninety degrees clockwise, and then the output end of the fifth electric push rod 709 extends to send the second mounting plate 712 and the test paper 714 to the inside of the distribution cabinet body 101, and then the output end of the fourth electric push rod 703 retracts to drive the connecting piece 706 to move downward, so that the test paper 714 also moves downward and fits the inner bottom end of the distribution cabinet body 101, and the vacuum suction cup 713 releases the adsorption, so that the test paper 714 is placed on the inner bottom end of the distribution cabinet body 101;

[0079] S4, the output end of the first drive motor 402 drives the bottom frame 405 to rotate 90 degrees clockwise to reset, and with the cooperation of the second electric push rod 609 and the second drive motor 608, the cabinet door 102 is also reset and locked, and finally the output end of the fourth stepper motor 605 drives the fourth screw rod 602 to rotate back and forth, so that the lifting plate 604 and the nozzle 613 move up and down as a whole, and the nozzle 613 is in the open state to spray water. After a threshold time, the above operation is repeated to open the cabinet door 102 and send the second mounting plate 712 to the inside of the distribution cabinet body 101 again, and the second drive wheel 708 is driven by the output end of the fourth drive motor 707 to rotate, so that the second mounting plate 712 rotates, and the camera 715 faces downward to shoot the test paper 714 to observe the test paper. Is there water on the test paper 714? Because in real life, heat dissipation holes are usually opened on both sides of the power distribution cabinet body 101, and the left and right side walls of the power distribution cabinet body 101 in the present invention are completely blocked by the vertical plates of the L-shaped plate 205, so water will not enter the inside of the power distribution cabinet body 101 through the heat dissipation holes. If the sealing of the connection between the power distribution cabinet body 101 and the cabinet door 102 is poor and causes water to enter, then the water will definitely flow to the bottom of the inside of the power distribution cabinet body 101. This is an important reason for placing the test paper 714 at the bottom of the inside of the power distribution cabinet body 101. If there is water on the test paper 714, it is determined that the sealing of the connection between the power distribution cabinet body 101 and the cabinet door 102 is poor, and it is an unqualified product. If there is no water on the test paper 714, it is determined that the sealing is good and it is a qualified product.

[0080] It is worth mentioning here that in real life, some distribution cabinet doors 102 are also provided with transparent observation windows. The present invention also adaptively arranges the third electric push rod 611 and the extrusion plate 612 to cooperate with each other, so as to detect the strength of the transparent observation window, thereby further improving the practicality and applicability of the device.

[0081] S5. If the power distribution cabinet body 101 is a qualified product, the next step of testing is carried out, and the above steps are repeated. The cabinet door 102 is reset and locked, and the second screw rod 406 is driven to rotate by the output end of the second stepper motor 409, so that the second movable plate 408 moves to the left, and the top of the connecting block 505 is in contact with the right bottom wall of the cabinet door 102. After that, the third screw rod 501 is driven to rotate by the output end of the third stepper motor 504, so that the clamping block 503 moves downward, and the clamping block 503 abuts the top wall of the right side of the cabinet door 102. The clamping block 503 and the connecting block 505 cooperate to clamp the right side of the cabinet door 102, and then the first gear 403 is driven to rotate by the output end of the first drive motor 402 to simulate the operation of "forcibly pulling open" the cabinet door 102, and observe whether the cabinet door 102 will be deformed and separated from the power distribution cabinet body 101 under "forcible pulling open";

[0082] S6. If the cabinet door 102 does not deform or separate from the distribution cabinet body 101 when it is "forced to be pulled open", the next detection operation is carried out, and the above steps are repeated to open the cabinet door 102, place the test paper 714 on the inner bottom of the distribution cabinet body 101, and perform a water spraying operation. After a threshold time, observe whether there is water on the test paper 714. If there is water, it means that the cabinet door 102 is "forced to be pulled open", and the sealing of the connection between the distribution cabinet body 101 and the cabinet door 102 is destroyed. The present invention is fully automated and does not require the participation of staff, thereby ensuring the safety of the test and meeting the needs of the staff.
