It is a light wall with decorative effect commonly used in modern large and high-rise buildings. The aluminum veneer of the building curtain wall often needs to be welded at the cut corner during processing, and has a corner code riveted at the folded edge.

[0003] In the prior art, a welding device for processing building curtain wall aluminum veneer is disclosed in the utility model patent with publication number CN210046136U, and an aluminum alloy frame welding device for a face frame glass curtain wall is disclosed in the invention patent application with publication number CN119927545A. In the above-mentioned solutions, only the aluminum veneer can be welded, and the riveting needs to be operated in the later period. The two operations are carried out separately, which prolongs the production cycle and reduces the efficiency.

[0054] The working principle of the curtain wall aluminum veneer assembling and welding equipment is as follows:

[0055] When the equipment is used for welding and assembling the curtain wall aluminum veneer, the riveting operation and the welding operation are synchronously performed.

[0056] Before assembly, a plurality of corner codes and rivets are respectively placed in the plurality of first vertical pipes 2 and the second vertical pipes 3, under the action of gravity, the corner codes and the rivets automatically move downward, and the corner codes and the aluminum veneer are punched at the corresponding positions.

[0057] During assembly, the aluminum veneer to be assembled is horizontally placed on the upper side of the base 1 at the central position, the folded edge faces upward, then the equipment is started through the control panel, the second motor 40 drives the transmission belt 43 to rotate through the driving pulley 41, the transmission belt 43 drives the two driven pulleys 42 to rotate, the two driven pulleys 42 drive the two frame bodies 37 to synchronously rotate, so that the two frame bodies 37 drive the pressing plate 19 to move downward, and the pressing plate 19 drives the second cylinder 20 and the truss 5 to move downward.

[0058] The pressing plate 19 moves down, so that the push assembly and the clamping assembly are respectively aligned with the inner side and the outer side of the aluminum single plate, then the first motor 26 starts to drive the first gear 27 and the third gear 36 to rotate, the first gear 27 drives the four racks 28 to move synchronously, the third gear 36 drives the four second gears 35 to rotate, the four racks 28 drive the corresponding slide rods 23 to move, the slide rods 23 drive the clamping frame 21 to move, the clamping frame 21 drives the two pressing wheels 22 to move, which are respectively in contact with the two outer sides of the corner, the second gear 35 drives the corresponding first screw 31 to rotate, the first screw 31 drives the slide bracket 29 to move, the slide bracket 29 drives the two pressing blocks 30 to contact with the inner side wall of the aluminum single plate, and the four sets of pressing wheels 22 and the four sets of pressing blocks 30 move synchronously, so that the aluminum single plate is clamped after being centered, and the positioning and clamping of the aluminum single plate are completed.

[0059] When the pressing plate 19 moves down, the pressing plate 19 stays on the upper side of the aluminum single plate, approaches but does not adhere to the aluminum single plate, so as to leave space for the centering movement of the aluminum single plate, and after the centering is completed, the pressing plate 19 moves down to press the aluminum single plate on the base 1.

[0060] After the aluminum single plate is positioned and clamped, welding and riveting operations are performed, the rivet holes on the clamped aluminum single plate are aligned with the guide pipe 7, the corner code located on the inner side wall of the aluminum single plate and on the upper side of the two clamping plates 17, and the rivet holes on the corner code and the through holes of the guide pipe 7 are in concentric circles, then the first air cylinder 6 starts to extend the output end to drive the pressing head 8 to move and penetrate into the push hole 301 to push the bottommost rivet into the guide pipe 7, when the front end of the rivet rod moves between the multiple elastic plates 9, the rivet rod is automatically centered and aligned with the rivet hole under the clamping force of the elastic plate 9, and finally the rivet rod penetrates the rivet hole to penetrate the aluminum single plate and the corner code, and the rivet head is tightly attached to the outer side of the aluminum single plate, then the pressing head 8 is pressed against the outer side of the aluminum single plate, and the synchronous operation of riveting and welding can be performed.

[0061] When the riveting and welding synchronous operation is performed, the third air cylinder 33 is elongated to make the top iron 34 contact with the end of the rivet rod, and the output end of the laser welding device 10 is aligned with the gap at the corner of the aluminum single plate, the third air cylinder 33 is elongated to make the top iron 34 move close to the pressing head 8, under the extrusion force, the end of the rivet rod forms a bump, and the riveting is completed, at the same time when the third air cylinder 33 is elongated, the fourth air cylinder 14 is elongated, and the laser welding device 10 is started to perform the welding operation on the gap at the corner of the aluminum single plate, so as to realize the synchronous completion of the welding operation.

[0062] After the riveting and welding operations are completed, the first cylinder 6, the third cylinder 33 and the fourth cylinder 14 are retracted, so that the pressure head 8, the top iron 34 and the laser welding device 10 are reset. After the first cylinder 6 is disengaged from the push hole 301, the rivet falls, the bottommost rivet is aligned with the push hole 301, and the next riveting is prepared. Then the four second cylinders 20 are elongated, so that the truss 5 drives all the first vertical pipes 2 fixedly connected thereto to move upward. Since the bottommost corner bracket is fastened to the aluminum single plate by the rivet, when the first vertical pipe 2 moves upward, the compression clamp plate 17 is compressed, the clamp plate 17 compresses the spring 18, and finally the riveted corner bracket is disengaged from the two clamp plates 17. Then the clamp plate 17 is reset under the elastic force of the plurality of springs 18, and the corner bracket not riveted in the first vertical pipe 2 is sealed. The bottommost corner bracket moves downward under the action of gravity and falls on the two clamp plates 17 on the side, preparing for the next riveting.

[0063] After the disengagement is completed, the first motor 26 and the second motor 40 are started to release the restriction on the assembled aluminum single plate, drive the pressing plate 19 to move upward, and then move the aluminum single plate with completed welding and riveting out of the upper side of the base 1. The next aluminum single plate to be assembled is placed on the base 1, and the next cycle operation is performed.

[0064] The riveting and welding of the aluminum single plate are completed synchronously through the above-mentioned manner.

[0065] Under the cooperation of the welding mechanism and the riveting mechanism, the corner gap welding of the aluminum single plate and the riveting of the corner bracket can be completed synchronously, the operation cycle is shortened, and the efficiency is improved.

[0066] The extrusion stress of the rivet causes plastic deformation of the aluminum single plate. Since the riveting and welding are performed synchronously, when deformed, the welding area is in a hot melting state and can adapt to the extrusion plastic deformation. Subsequently, it is integrally formed, so that the influence of extrusion deformation on the welding contact can be eliminated, stress in the welding area can be avoided, and the welding quality can be ensured.

[0067] Under the cooperation of the riveting mechanism and the jig mechanism, the aluminum single plate and the corner bracket and the rivet can be automatically aligned, so that the assembly accuracy is ensured, and the rivet and the corner bracket are automatically transported, further improving the assembly efficiency.
