during operation, transport actuating mechanism drives the motion of transport module to put bed charge, well material and surface material in proper order in counterpoint welding platform A, concrete handling is:

firstly, a carrying driving mechanism drives two carrying modules G to move, so that one carrying module G is positioned right above a backing material storage device C, the other carrying module G is positioned right above an alignment welding platform A, then, a second vertical driving mechanism 4 in the two carrying modules G drives a carrying mechanism 2 to move vertically, so that backing materials are grabbed, and plates which are welded on the alignment welding platform A in a compounding manner are grabbed, wherein the plates are backing materials, middle materials and surface materials;

then, the carrying driving mechanism drives the two carrying modules G to move, so that the carrying module G which grabs the backing materials is positioned right above the alignment welding platform A, the carrying module G which grabs the plate materials which are subjected to composite welding is positioned right above the collecting device F, and then the second vertical driving mechanism 4 in the carrying module G which grabs the backing materials drives the carrying mechanism 2 to move downwards, so that the backing materials are placed on the alignment welding platform A; the second vertical driving mechanism 4 in the carrying module G which captures the composite welded plate materials drives the carrying mechanism 2 to move downwards, so that the composite welded plate materials are placed in the collecting device F;

then, the carrying driving mechanism drives the two carrying modules G to move, so that one carrying module G is positioned right above the middle material storage device D, the other carrying module G is positioned right above the fabric storage device E, and then the second vertical driving mechanism 4 in the two carrying modules G drives the carrying mechanism 2 to move vertically, so that the middle material and the fabric are grabbed;

then, the carrying driving mechanism drives the two carrying modules G to move, so that the carrying module G which is grabbed with the middle materials is positioned right above the alignment welding platform A, the carrying module G which is grabbed with the fabric is positioned right above the collecting device F, and then the second vertical driving mechanism 4 in the carrying module G which is grabbed with the middle materials drives the carrying mechanism 2 to move downwards, so that the middle materials are placed on the alignment welding platform A;

finally, the carrying driving mechanism drives the two carrying modules G to move, so that the carrying module G which is grabbed with the fabric is positioned right above the alignment welding platform A, and the other carrying module G is positioned right above the backing material storage device C; then, the second vertical driving mechanism 4 in the carrying module G which has grabbed the fabric drives the carrying mechanism 2 to move downwards, so that the fabric is placed on the alignment welding platform a.

In the above process, the specific grasping action of the handling module G is as follows:

when the device works, the second vertical driving mechanism 4 drives the carrying mechanism 2 to move vertically, so that the first sucker 2-1 and the second sucker 2-2 in the carrying mechanism 2 are in contact with a sheet material, then the driving piece drives the suction nozzle in the second sucker 2-2 to move upwards, so that the height of the second sucker 2-2 is higher than that of the first sucker 2-1, therefore, the height of a part of the sheet material adsorbed by the second sucker 2-2 is higher than that of a part of the sheet material adsorbed by the first sucker 2-1, and because the second sucker 2-2 is arranged on the side of the bracket and is positioned between the two first suckers 2-1, a gap exists between the part of the sheet material grabbed by the second sucker 2-2 and the next sheet material, and air is blown into the gap through the air blowing pipe 7 arranged on the first storage rack 6 in the backing material storage device C and the backing material storage device E, therefore, two adjacent plates are easily separated, and the carrying mechanism 2 is prevented from carrying a plurality of plates (fabric or backing materials) to the alignment welding platform A at the same time, so that the quality of ultrasonic hybrid welding is ensured.

After carrying backing material, well material and surface fabric all to counterpoint welded platform A when handling device, counterpoint welded platform A beats backing material, well material and surface fabric just, makes it put neatly, and the concrete process is:

the pressing driving mechanism drives the pressing rod 2-1a to move downwards so as to press three plates, wherein multiple groups of pressing devices 2a can be arranged, and the pressing effect is better. Then, the positive-beating driving mechanism drives the positive-beating plate 3-1a to move towards the direction of the limiting plate 5a, in the process, the positive-beating plate 3-1a is in contact with three plates and drives the three plates to move towards the direction of the limiting plate 5a until the end parts of the three plates are in contact with the limiting plate 5a, so that the positive-beating of the three plates in the X-axis direction or the Y-axis direction is completed by taking the limiting plate 5a as an alignment reference, and because the positive-beating device 3a and the two limiting plates 5a are arranged in the embodiment, the two limiting plates 5a are arranged at 90 degrees, and the positive-beating device 3a is also arranged at 90 degrees, so that the positive-beating of the three plates in the X-axis direction and the Y-axis direction can be realized. And in the process of being patted, the three plates are compressed by the compressing device 2a, so that the three plates can be prevented from floating upwards to cross the limiting plate 5a in the process of being patted, the smooth completion of the patting action is ensured, and the three plates are aligned. Then, the first vertical driving mechanism drives the ultrasonic welding head 4-1a to vertically move, so that the three plates are welded together. And then, the first vertical driving mechanism drives the ultrasonic welding head 4-1a to move upwards, and at the moment, three plates are pressed on the workbench 1a by the pressing device 2a, so that the three plates cannot be brought up when the ultrasonic welding head 4-1a moves upwards, and the separation of the ultrasonic welding head 4-1a and the plates is facilitated. And finally, the pressing driving mechanism drives the pressing rod 2-1a to move upwards to complete the ultrasonic composite welding process.

And finally, the conveying driving mechanism drives the two conveying modules G to move, the welded plates are conveyed to the collecting device F, and a new round of ultrasonic composite welding process is started.
