Existing beveling machines can achieve fast beveling of switch cabinet panels through precise mechanical design and advanced control technology. However, the quality of the panel itself cannot be detected during beveling, so it cannot be adjusted in real time according to the actual situation of the panel, which will affect the quality of beveling.

[0016] The limit assembly includes a mounting seat fixed on the bearing platform, a third drive is fixed on the top of the mounting seat, a limit block is fixed on the output end of the third drive, a limit slot is fixed on the side of the limit block close to the plate, and a plurality of pressure sensors 2 are arranged on the upper and lower sides of the limit slot, the limit slot matches the plate, and the third drive is started to extend so that the limit slot on the limit block contacts the side of the plate, thereby clamping the plate laterally. When the plate enters the limit slot, the upper and lower sides of the plate contact the pressure sensor 2, and the pressure value is set to a;

[0017] a is the normal pressure value of the upper and lower sides of the plate in contact with pressure sensor 2.

[0018] According to the above technical solution, the transverse transport assembly includes a lower shell fixed to the bottom of the carrying platform, and a conveyor belt arranged below the carrying platform, wherein:

[0019] The width of the tray is smaller than the width of the conveyor belt, and the connecting plate is fixed in the middle of the lower shell.

[0020] According to the above technical solution, the clamping strip 1 and the clamping strip 2 are provided with a step shape on one side close to the plate, so as to facilitate matching with the side of the plate.

[0029] When the pressure sensor 1 with a force greater than the constant clamping force is distributed sparsely on the clamping strip 1 and the clamping strip 2, it means that the protrusions on the side of the plate are also distributed sparsely. When the pressure sensor 1 with a force greater than the constant clamping force is distributed more concentratedly on the clamping strip 1 and the clamping strip 2, it means that the protrusions on the side of the plate are also distributed more concentratedly. When the protrusions are distributed more concentratedly, it is easy to affect the subsequent clamping quality and directly remove the plate.

[0030] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the present invention is provided with pressure sensor 1 and pressure sensor 2. When the protrusions are scattered, the force is detected by pressure sensor 2. If the pressure detected by pressure sensor 2 is still equal to a, it means that the plate has not been deformed and subsequent cutting can be performed. If the pressure detected by pressure sensor 2 is greater than a, it means that the plate has been deformed under a greater pressure, indicating that the quality of the plate is poor.

[0031] By providing a cutting mechanism, when the protrusions on the side of the plate are dispersed and there is no deformation, the cutting mechanism is first controlled to run half of the working stroke during corner cutting, and the shooting unit is used to identify whether the cutting angle has changed. If it has changed, the cutting device is driven to shift to the appropriate angle and cut again, and the first corner cutting is trimmed to ensure the quality of the corner cutting.

[0062] The working state of the angle cutting mechanism is set by the controller 5 to achieve a suitable angle cutting angle.

[0063] The second pressure sensor 29 , the photographing unit 28 , the fifth driver 15 , the fourth driver 26 , and the sixth driver 16 are all electrically connected to the controller 5 .

[0064] Working principle:

[0065] The plate is transported to the top of the pallet 7 via the conveyor belt 3, and the first drive 6 is started to extend to transport the plate to between the two groups of limit components. At this time, the third drive 10 is started to extend, driving the limit block 11 to clamp the plate, and then the second drive 18 is controlled to extend so that the clamping bar 22 contacts the side of the plate. Through the cooperation of the clamping bar 1 23 and the clamping bar 22, the plate can be clamped through the cooperation of the two groups of limit blocks 11 and the two groups of clamping bars, and then the cutting mechanism is controlled to cut the angle of the plate.

[0066] During the clamping process, the clamping pressure is detected by the pressure sensor 27 and the signal is transmitted to the controller 5 to determine whether the side of the plate is flat. The cutting method of the cutting mechanism is adjusted according to the flatness of the plate surface:

[0067] Specifically, since multiple groups of pressure sensors 27 are arranged on the clamping bar 1 23 and the clamping bar 22, when the clamping bar 1 23 and the clamping bar 22 are in contact with the plate, the pressure sensor 27 will detect the pressure between the clamping bar 1 23 and the clamping bar 22 and the plate in real time, that is, the clamping force is transmitted to the controller 5, and the constant stroke of the second drive 18 is set in the controller 5, and the constant clamping force of the clamping bar 1 23 and the clamping bar 22 is set at the same time. Therefore, when the clamping force displayed by each pressure sensor 27 is equal, it means that the side of the plate is flat. At this time, the angle cutting mechanism is started by the controller 5 to work normally.

[0068] When the clamping force of the pressure sensor 27 which is less than or equal to forty percent is greater than the constant holding force, it means that there is a protrusion on the side of the plate that squeezes the pressure sensor 27. Furthermore, when the pressure sensor 27 which is greater than the constant holding force is distributed more sparsely on the clamping strip 1 23 and the clamping strip 2 22, it means that the protrusions on the side of the plate are also distributed more sparsely. When the pressure sensor 27 which is greater than the constant clamping force is distributed more concentratedly on the clamping strip 1 23 and the clamping strip 22, it means that the protrusions on the side of the plate are also distributed more concentratedly. When the protrusions are distributed more concentratedly, it is easy to affect the subsequent clamping quality and directly remove the plate.

[0069] Since the stroke of the second drive 18 is a constant distance, when the protrusions are scattered, it means that the greater pressure on the side of the plate is also concentrated, which can easily cause the plate to be squeezed and deformed. At this time, the force condition is detected by the pressure sensor 29. If the pressure detected by the pressure sensor 29 is still equal to a at this time (a is the normal pressure value of the upper and lower sides of the plate in contact with the pressure sensor 29), it means that the plate has not been deformed and subsequent corner cutting can be carried out. If the pressure detected by the pressure sensor 29 is greater than a, it means that the plate has been deformed under a greater pressure (such as Fig. 9 As shown), it indicates that the plate is of poor quality, and the controller 5 transmits a signal to the staff, who remove the plate.

[0070] Furthermore, when the protrusions on the side of the plate are dispersed and there is no deformation, in order to ensure the quality of the corner cutting, the cutting mechanism is first controlled to run half of the working stroke, and then the cutting mechanism is controlled to return to its original position. At this time, the photo of the corner of the plate is taken by the shooting unit 28 and transmitted to the controller 5 to identify whether the angle of the corner cutting has changed. If the angle has changed, it means that the protrusions on the surface of the plate have affected the clamping force, resulting in the plate being offset during cutting, resulting in the plate corner offset movement angle, so the signal is transmitted to the controller 5, and the controller 5 identifies the offset angle of the corner cutting. If the offset angle is within the allowable range, the controller 5 transmits the signal to the fourth drive 26 to drive the mounting plate 13 to rotate, thereby driving the cutting device 17 to offset to a suitable angle and cut the angle again, and trim the first corner cutting to ensure the quality of the corner cutting. If the controller 5 identifies that the offset angle is greater than the allowable range, it means that the offset amplitude of the plate is large. At this time, the processing of the plate is suspended. This step can realize real-time adjustment of the cutting mechanism according to the actual situation of the plate to ensure the quality of the corner cutting.

[0071] When the clamping force of the pressure sensor 27 is greater than the constant clamping force by more than 40%, it means that there are more protrusions on the side of the plate. At this time, a signal is transmitted to the controller 5 to suspend processing and inform the staff to remove the plate and deal with the protrusions on the side of the plate.

[0072] When the corner cutting of the plate is completed, the pushing assembly is controlled to return to its original position, and then the first drive 6 is controlled to contract to drive the tray 7 to descend. At this time, the conveyor belt 3 is controlled to transport the next plate to the top of the tray 7, and the corner cutting work is repeated.

[0073] Through the above steps, when the control cabinet plate is cut corners, the quality of the plate can be judged by clamping the plate, thereby further improving the quality of the plate cutting corners.
