[0002] In sheet metal processing, sheets are often fed one by one onto a conveyor belt. Existing equipment typically uses suction cups for sheet transport. However, suction cup structures often require large vacuum equipment, resulting in significant noise during operation. Furthermore, using suction cups to grip sheets demands a high degree of surface flatness, making them unsuitable for separating sheets with rough surfaces. Additionally, due to the large area and weight of some sheets, the robotic arms used to grip them with suction cups occupy considerable space, leading to higher operating costs.

[0022] The vehicle body lifting control frame 2 is located below the conveyor belt. The vehicle body lifting control frame 2 includes a lifting module 21, a channel rail 22, and a base frame 23. A lifting module 21 is set at each of the four corners of the base frame 23. Two channel rails 22 are parallel to each other, and each channel rail 22 is connected to two lifting modules 21. Rollers are set on both sides of the pallet vehicle body 3. The rollers extend into the channel rails 22 and roll in cooperation with the channel rails 22. The straightening mechanism 6 includes a floating seat 65, a wheel frame 62, a positioning frame 64, a positioning wheel 61, and an end seat 73. The floating seat 65 is vertically arranged.

The push block 67 can abut against the side of the plate 5 and push the other side of the plate 5 to the hook 66. When the straightening mechanism 6 rises, it lifts the end of the plate 5 that is close to the belt conveyor 1, so that the pallet trolley 3 can extend under the plate 5.
[0025] The pallet device located at the end of the pallet vehicle body 3 is a first pallet device 32. The first pallet device 32 includes a first motor 321, a first gear 322, a first shaft 323, and a first support roller 324. The two ends of the first shaft 323 are rotatably connected to the pallet vehicle body 3, and multiple first arms are vertically connected to the first shaft 323. The end of each first arm is rotatably connected to a first support roller 324.

[0027] The lifting mechanism 7 includes a lifter 71 and a traversing mechanism 72; the traversing mechanism 72 is mounted on the lifter 71, and its end is connected to an end seat 73. The traversing mechanism 72 includes a toothed rod 721 and a drive gear 722 that mesh with each other; the end seat 73 is mounted on the end of the toothed rod 721.
[0028] The working process of the plate separating device in this embodiment is as follows: 1. Use a forklift or other transport vehicle to transport the vertically overlapping plates 5 together to the end of the belt conveyor 1. At this time, the length direction of the plates 5 should be at an angle of 10-20° with the conveying direction of the belt conveyor 1. 2. The drive gear 722 controls the position of the toothed rod 721, so that the straightening mechanism 6 is kept away from the plate 5; the lifting mechanism 7's lifting device 71 is activated, so that the straightening mechanism 6 can move to a certain height position of the lifting device 71; at this time, the push block 67 is at the same height position as the uppermost plate 5. When the two straightening mechanisms 6 move closer to each other under the control of the corresponding toothed rods 721, the alignment wheel 61 first abuts against the plate 5, thereby driving the floating seat 65 and the push block 67 to move, so that the push block 67 only abuts against the side of the uppermost plate 5; when the two straightening mechanisms 6 move closer together, the push block 67 pushes the plate 5 to rotate relative to the plate 5 below it, so that the length direction of the plate 5 is consistent with the conveying direction of the belt conveyor 1. At this time, the other corner of the plate 5 is suspended in the air and hooked by the hook 66. 3. When the push block 67 abuts against the side of the plate 5 and the hook 66 hooks the corner of the other side of the plate 5, the lifting device 71 pushes the straightening mechanism 6 to rise, which can make the end of the plate 5 near the belt conveyor 1 tilt upward; thereby forming a gap between the plate 5 and the plate 5 below it for the pallet car body 3 to extend into. 4. The lifting module 21 of the vehicle body lifting control frame 2 moves the channel rail 22 upward, thereby causing the pallet vehicle body 3 to move up and down and align with the gap below the plate 5; then the rollers around the pallet vehicle body 3 roll, causing one end of the pallet vehicle body 3 to move along the channel rail 22 and extend out of the belt conveyor 1, and then the end of the pallet vehicle body 3 is inserted into the gap below the plate 5; during this process, the guide 34 on the pallet vehicle body 3 moves along the upper surface of the lower plate 5 until the extension length of the end of the pallet vehicle body 3 exceeds half the length of the plate 5; 5. The first motor 321 of the first pallet 32 and the second motor 331 of the second pallet 33 rotate and control the first arm and the second arm to lift upward, so that the first roller 324 and the second roller 335 abut against the lower surface of the plate 5 lifted by the straightening mechanism 6; when the vehicle body lifting control frame 2 rises again, the pallet vehicle body 3 can drive the plate 5 to rise, and when the heights of the first roller 324 and the second roller 335 are different, the inclination of the plate 5 can be adjusted so that the upper inclined end of the plate 5 is consistent with the belt height of the belt conveyor 1; 6. During the process of the pallet carriage 3 driving the plate 5 to rise, the plate 5 can drive the floating seat 65 to rise through the positioning wheel 61 and compress the telescopic spring 74. When the distance sensor 75 detects that the distance between the positioning frame 64 and the L-shaped frame is less than the threshold, the lifter 71 controls the end seat 73 and the L-shaped frame to rise a certain distance. The pressure applied to the plate 5 by the positioning wheel 61 is used to prevent the plate 5 from slipping off the pallet carriage 3 in an inclined state. 7. When the height and inclination of the plate 5 are sufficient to allow it to be fed into the belt conveyor 1, the drive gear 722 controls the toothed rod 721 to move outward a certain distance, so that the positioning wheel 61 does not disengage from the plate 5, but the floating seat 65 and the push block 67 disengage from the plate 5; the plate feeding motor 334 starts and drives the second support roller 335 to rotate, thereby feeding the plate 5 obliquely into the belt conveyor 1; during this process, the positioning wheel 61 changes direction under the action of the friction of the plate 5, and both the wheel frame 62 and the positioning wheel 61 deflect in the direction of movement of the plate 5 and compress the spiral spring 63 to avoid the influence of the orientation of the positioning wheel 61 being perpendicular to the direction of movement of the plate 5 on the conveying of the plate 5; 8. After the plate 5 is delivered to the belt conveyor 1, the pallet car body 3, the straightening mechanism 6, the car body lifting control frame 2, the lifting mechanism 7 and other components are reset, and the next plate 5 is conveyed again.
[0029] Example 2 like Figures 1 to 7 As shown, this embodiment designs an intelligent board separation system, including a PLC controller and the intelligent board separation device described in Embodiment 1; the PLC controller is electrically connected to the sensors and motors installed on the pallet cart body 3, the lifting mechanism 7, and the straightening mechanism 6 to control the coordinated operation of each component.
[0030] The above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation; it is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom remain within the scope of this technology.
