The top of the conveyor belt 312 is lower than the top wall of the conveyor frame 310, and the width of the conveyor belt 312 can be smaller than the width of the sheet 800, so that when the sheet 800 falls on the conveyor belt 312, the conveyor frame 310 can be attached to two sides of the sheet 800 to limit the sheet 800, and the sheet 800 is prevented from tilting.

The carrier 310 is close to the side of the carrier 400 and can be further provided with a pressing wheel 314, two pressing blocks 315 are fixed on the carrier 310 through bolts, a pressing shaft 316 is fixed between the two pressing blocks 315, the pressing wheel 314 is rotationally connected to the pressing shaft 316, the pressing wheel 314 is located above the conveying belt 312, and the distance between the pressing wheel 314 and the conveying belt 312 can be slightly larger than the thickness of the sheet 800.

In some embodiments of the application, the sheet loading apparatus further comprises: a detection assembly and a controller. The detection assembly is used to detect the position and number of the sheets 800. The controller is in communication with the detection assembly, the ejector assembly 200, the feeding mechanism 300, and the moving mechanism 500, respectively, to control the movement of the sheet 800 according to its position and number.

Specifically, the detecting assembly may include a plurality of detecting units, which may be respectively disposed on different mechanisms, for example, a distance sensor, a contact switch, etc. may be disposed on the grabbing assembly, so as to determine whether the vacuum nozzle 322 acts to adsorb the sheet 800 by detecting the distance between the sheet 800 and the vacuum nozzle 322. A gauge or other sensor may be provided on the transport assembly to control the amount of sheet 800 transported to determine whether and how the carriage 420 is to be moved. The controller can adopt a PLC module and the like, and a corresponding control program is arranged in the controller to control the corresponding mechanism to act according to the result detected by the detection component.

When the sheet loading device operates, the position and the number of the sheets 800 are detected in real time through the detection component, the detection result is fed back into the controller, the controller controls the corresponding mechanism to act according to the detection result, for example, after the controller receives the contact between the material grabbing component and the sheets 800, the controller can control the vacuum suction nozzle 322 to act to adsorb the sheets 800, then control the material grabbing driving piece 323 to operate to move the material grabbing plate 321 to the upper part of the conveying component, and then control the vacuum suction nozzle 322 to deflate so as to automatically place the sheets 800 on the conveying belt 312 of the conveying component, so that the automatic grabbing, releasing and conveying of the sheets 800 can be realized. The controller then controls the automatic operation of the conveying assembly and the moving mechanism 500 so that the placement of the sheet 800 can be automatically completed to improve the automation degree of the whole device.

When the contact switch 325 contacts the sheet 800 while gripping the sheet 800, it can be determined that the vacuum nozzle 322 is in contact with the sheet 800 at this time, and the controller controls the vacuum nozzle 322 to act to suck the sheet 800 to complete gripping. The grabbing driving member 323 is controlled to drive the grabbing plate 321 to move towards the conveying assembly, so that the sheet 800 is placed on the conveying assembly. Because the distance between the grabbing plate 321 and the conveying assembly is constant, only one moving time is required to be set, and when the controller detects that the moving time of the grabbing plate 321 is equal to or longer than the moving time, the grabbing plate 321 can be automatically determined to be positioned on the conveying assembly, so that the sheet 800 can be accurately placed on the conveying assembly.

When the conveying assembly conveys the sheets, the counter 317 can record the number of the sheets 800 in real time, and the number of the grooves 421 in the material carrying frame 420 corresponds to the number of the sheets 800 one by one, so that according to the number recorded by the counter 317, it can be determined which groove 421 corresponds to the conveying assembly, and therefore the sheets 800 can be automatically placed in the corresponding groove 421.
