The using method of the automatic feeding machine comprises the following steps:
S1, stacking a plurality of planar suspension bracket component parts on a material tray 223 of a material tray assembly 22, and then placing one planar suspension bracket component part on a centering device 25 for positioning;
in this step, the suspension bracket component work may not be added to the centering device 25. Therefore, when the feeding device 26 feeds materials for the first time, although the feeding device 26 and the unstacking device 24 work synchronously, the centering device 26 has no suspension bracket part workpiece, so the feeding device 26 has no suspension bracket part adsorption and is in idle running; while the unstacking device 24 transfers the suspended support component parts of the tray assembly 22 to the centering device 25 for processing by the feeder device 26 in the next cycle. Starting from the second loading, the loading device 26 starts to process the suspension holder component pieces transferred from the last cycle of the unstacking device 24 to the centering device 25.
S2, driving the unstacking device 24 and the feeding device 26 to descend and respectively adsorbing the workpieces of the suspension bracket parts of the tray assembly 22 and the centering device 25;
In this step, after the unstacking device 24 removes a piece of suspension bracket component parts from the tray assembly 22, the tray assembly 22 automatically lifts the tray 223, making the level of the uppermost suspension bracket component parts inconvenient. In this way, the distance that the unstacking device 24 sucks the workpiece every time is unchanged, and the height that the tray assembly 22 ascends every time is the same, so that automatic control is easier to realize.
S3, starting a transmission assembly to drive the unstacking device 24 and the feeding device 26 to move a certain distance along the transverse guide rail 27, wherein at the moment, the workpiece of the suspension bracket parts adsorbed by the unstacking device 24 is positioned right above the centering device 25, and the workpiece of the suspension bracket parts adsorbed by the feeding device 26 is also positioned right above the die of the first press 1;
Since the unstacking device 24 and the feeding device 26 are fixed to the belt 28 at the same time, they have the same moving speed and moving distance. In this step, when the tray device 22, the centering device 25, and the first press 1 are installed, it is ensured that the centering device 25 is located at the midpoint of the tray device 22 and the first press 1 to ensure the operational cooperation of the unstacking device 24 and the loading device 26. In this way, the positions of the tray device 22, the centering device 25 and the first press 1 are accurately fixed, so that the workpieces of the parts of the suspension bracket can be quickly and accurately transferred.
S4, transferring the absorbed suspension bracket part workpieces to a centering device 25 by a unstacking device 24, and positioning the suspension bracket part workpieces by the centering device 25; the feeding device 26 puts the absorbed suspension bracket part workpiece into the die of the first press 1, preferably, in order to ensure that the suspension bracket part workpiece accurately falls into the die of the first press 1, the feeding device 26 drives the feeding end effector to descend by utilizing the second transmission device before the suspension bracket part workpiece is put into the die of the first press 1, so that the absorbed suspension bracket part is abutted against the die of the first press 1, and then the suspension bracket part workpiece is loosened;
In this step, the centering device 25 accurately positions the suspension bracket component workpieces transferred from the unstacking device 24, so that the positions of the suspension bracket component workpieces gripped from the centering device 25 by the feeding device 26 are the same each time, and the feeding device is convenient to accurately transfer the suspension bracket component workpieces to the position right above the die of the first press 4. Therefore, the workpiece transfer accuracy of the parts of the suspension bracket is high, errors are not easy to occur, and the overall stamping efficiency is improved. Meanwhile, when the suspended support part workpiece absorbed by the feeding device 26 is positioned right above the die of the first press 1, the suspended support part workpiece is at a certain distance from the die, for example, the suspended support part workpiece is allowed to fall down by itself, and position deviation easily occurs in the falling process, so that the suspended support part workpiece cannot enter a preset position, and the workpiece stamping is affected. Therefore, the workpiece of the suspension bracket part accurately reaches the preset position by the descending of the feeding device 26 and then is loosened, and the work flow is safer and more reliable.
S5, after the unstacking device 24 and the feeding device 26 are used for completing the transfer of the parts of the plane suspension bracket, the transmission assembly drives the unstacking device 24 and the feeding device 26 to the initial positions (the initial positions are the positions before the unstacking device 24 and the feeding device 26 descend in the step S2);
s6, repeating the steps S2-S5 until the workpieces of the suspension bracket parts on the material tray assembly 22 and the centering device 25 are processed.
