The use method of the automatic feeding machine comprises the following steps:

s1, stacking a plurality of planar suspension bracket part workpieces on the tray 223 of the tray assembly 22, and then placing a planar suspension bracket part workpiece on the centering device 25 for positioning;

in this step, no suspension bracket component work piece may be added to the centering device 25. Therefore, when the feeding device 26 is used for feeding for the first time, although the feeding device 26 and the unstacking device 24 work synchronously, the centering device 26 does not have a workpiece with a suspension bracket component, so that the feeding device 26 does not have the adsorption of the suspension bracket component and is in no-load operation; while the unstacking assembly 24 transfers the suspended support component pieces of the tray assembly 22 to the centering assembly 25 and the infeed assembly 26 for processing in the next cycle. From the second feeding, the feeding device 26 starts processing the work pieces of the suspension frame parts transferred from the unstacking device 24 to the centering device 25 in the previous cycle.

S2, driving the unstacking device 24 and the feeding device 26 to descend and respectively adsorbing the suspension bracket parts and workpieces of the tray assembly 22 and the centering device 25;

in this step, after the unstacking device 24 removes one piece of suspended support component workpiece from the tray assembly 22, the tray assembly 22 automatically raises the tray 223 so that the level of the uppermost suspended support component workpiece is maintained at an inconvenient level. In this way, the distance of the unstacking device 24 for descending and sucking the workpieces each time is unchanged, and the height of the tray assembly 22 for ascending each time is the same, so that automatic control is easier to realize.

S3, starting the transmission assembly to drive the unstacking device 24 and the feeding device 26 to move for a certain distance along the transverse guide rail 27, wherein at the moment, the suspension bracket part workpiece adsorbed by the unstacking device 24 is positioned right above the centering device 25, and the suspension bracket part workpiece 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 simultaneously fixed on the belt 28, 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, the centering device 25 is located at the midpoint between the tray device 22 and the first press 1, so as to ensure the working cooperativity of the unstacking device 24 and the feeding device 26. Therefore, 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 suspension bracket parts can be quickly and accurately transferred.

S4, the unstacking device 24 transfers the suspended support component workpiece adsorbed by the unstacking device to the centering device 25, and the centering device 25 positions the suspended support component workpiece; the feeding device 26 puts the suspended bracket parts and workpieces adsorbed by the feeding device into the die of the first press 1, preferably, in order to ensure that the suspended bracket parts and workpieces accurately fall into the die of the first press 1, before the feeding device 26 puts the suspended bracket parts and workpieces to work, the feeding end pickup is driven to descend by the second transmission device, so that the adsorbed suspended bracket parts and workpieces are close to the die of the first press 1, and then the suspended bracket parts and workpieces are released;

in this step, the centering device 25 precisely positions the suspension frame part workpieces transferred from the unstacking device 24, so that the positions of the suspension frame part workpieces captured by the feeding device 26 from the centering device 25 at each time are the same, which is convenient for the feeding device to accurately transfer the suspension frame part workpieces to the position right above the mold of the first press 4. Therefore, workpieces of parts of the suspension bracket are high in transferring accuracy, errors are not prone to occurring, and the overall stamping efficiency is improved. Meanwhile, when the suspension bracket part workpiece adsorbed by the feeding device 26 is positioned right above the die of the first press 1, the suspension bracket part workpiece has a certain distance from the die, and if the suspension bracket part workpiece falls down, the position deviation is easy to occur in the falling process, so that the suspension bracket part workpiece cannot enter a preset position, and the workpiece stamping is influenced. Therefore, the feeding device 26 descends to enable the workpiece of the suspension bracket parts to accurately reach the preset position and then the workpiece is loosened, and the working process is safer and more reliable.

S5, after the unstacking device 24 and the feeding device 26 complete the workpiece transfer of the planar suspension bracket parts, the transmission assembly drives the unstacking device 24 and the feeding device 26 back to the initial positions (the initial positions are the positions before the unstacking device 24 and the feeding device 26 descend in step S2);

and S6, repeating the steps S2-S5 until the workpieces of the suspension bracket parts on the tray assembly 22 and the centering device 25 are processed.

The first suction pad 241, the second suction pad 262, and the third suction pad 73 are vacuum pads, and the suction or release of the suspension holder component workpiece by the first suction pad 241, the second suction pad 262, and the third suction pad 73 is controlled by vacuum suction.

b. starting the first press 1, and punching and forming a workpiece of the planar suspension bracket part;

c. the material taking robot 3 takes out the punched suspension bracket part workpiece from the first press 1 and then transfers the workpiece to the feeding robot 4; the feeding robot 4 receives the suspension bracket part workpiece from the material taking robot 3, then transfers the suspension bracket part to a die of a second press 5 for punching, and the suspension bracket part workpiece is processed;

d. and the blanking robot 6 takes out the machined suspension bracket part workpiece and puts the workpiece into the material frame.

In the step a, the automatic feeding machine 2 feeds materials to the first pressing machine 1 in a reciprocating mode, and one-time feeding is completed within 8-10 seconds. In the step c, the taking robot 3 takes out the workpiece of the suspension bracket from the first pressing machine 1 after adsorbing the upper surface of the workpiece of the suspension bracket, and the taking robot 3 overturns the workpiece of the suspension bracket by 180 degrees so that the lower surface of the workpiece of the suspension bracket faces upwards. Therefore, when the material taking robot 3 and the material feeding robot 4 are used for handing over the suspension bracket parts, the gripping device 7 of the material feeding robot 4 moves to the position above the suspension bracket parts on the material taking robot 3, then adsorbs the lower surfaces of the suspension bracket parts, and then transfers the suspension bracket parts to the second pressing machine 5.
