Description

Technical Field

[0001] The present invention relates to the field of welding technology, in particular to curtain wall aluminum single panel assembly welding equipment and process. Background Art

[0002] Aluminum veneer curtain wall is the exterior wall enclosure of curtain wall-type buildings. It does not bear weight and is hung on the main structure of the building like a curtain, so it is also called "curtain wall". It is a lightweight wall with decorative effects commonly used in modern large and high-rise buildings. The aluminum veneer of the building curtain wall often needs to be welded at the corners during processing and riveted with corner brackets at the folded edges. During installation, you only need to connect the corner brackets to the iron frame on the wall with fasteners. It is very convenient to install and also facilitates later maintenance and replacement.

[0003] In the prior art, for example, the utility model patent with the publication number CN210046136U discloses a welding device for processing aluminum veneers for building curtain walls, and the invention patent application with the publication number CN119927545A discloses an aluminum alloy frame welding device for exposed frame glass curtain walls. In the above schemes, only aluminum veneers can be welded, and riveting requires a later operation. The two operations are performed separately, which prolongs the production cycle and reduces efficiency. Moreover, during riveting, due to the expansion of the rivets, extrusion stress is generated on the folded edge of the aluminum veneer, which easily causes plastic expansion deformation of the folded edge of the aluminum veneer, thereby causing cracks at the weld, affecting the production and assembly quality of the aluminum veneer.

[0030] The working principle of the curtain wall aluminum veneer assembly welding equipment involved in this application is as follows: When using this equipment to weld and assemble curtain wall aluminum panels, riveting and welding operations are carried out simultaneously.

[0031] Before assembly, batches of angle brackets and rivets are placed in multiple first vertical tubes 2 and second vertical tubes 3 respectively. Under the action of gravity, the angle brackets and rivets automatically move downward, and holes are punched at corresponding positions of the angle brackets and aluminum panels.

[0032] During assembly, the aluminum single plate to be assembled is placed horizontally in the center of the upper side of the base 1 with the folded edge facing upwards, and then the equipment is started through the control panel. The second motor 40 drives the transmission belt 43 to rotate through the active pulley 41, and the transmission belt 43 drives the two driven pulleys 42 to rotate. The two driven pulleys 42 respectively drive the two second screws 38 to rotate synchronously, so that the two frames 37 drive the pressure plate 19 to move downward, and the pressure plate 19 drives the second cylinder 20 and the truss 5 to move downward.

[0033] The pressing plate 19 moves downward, so that the pushing assembly and the clamping assembly are respectively aligned with the inner and outer angled surfaces of the folded edge of the aluminum veneer, and then the first motor 26 is started, driving 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 rod 23 drives the clamping frame 21 to move, the clamping frame 21 drives the two pressure wheels 22 to move and contact the two outer side surfaces of the folded angle respectively, the second gear 35 drives the corresponding first screw 31 to rotate, the first screw 31 drives the slide 29 sleeved thereon to move, the slide 29 drives the two pressure blocks 30 thereon to contact the inner side wall of the folded edge of the aluminum veneer, the four groups of pressure wheels 22 and the four groups of pressure blocks 30 move synchronously, so that the aluminum veneer is centered and then clamped, completing the positioning and clamping work of the aluminum veneer.

[0034] When the pressing plate 19 moves downward, the pressing plate 19 stays on the upper side of the aluminum veneer, close to but not touching the aluminum veneer, leaving space for the centering of the aluminum veneer. After the centering is completed, the pressing plate 19 moves downward to press the aluminum veneer onto the base 1.

[0035] After the aluminum veneer is positioned and clamped, welding and riveting operations are carried out. The rivet holes on the folded edge of the aluminum veneer after clamping are aligned with the conduit 7. The angle code at the bottom is attached to the inner wall of the aluminum veneer and is located on the upper side of the two clamping plates 17. The rivet holes on the angle code, the rivet holes on the aluminum veneer and the through holes of the conduit 7 are in a concentric circle state. Then the first cylinder 6 is started, the output end is extended, and the pressure head 8 is driven to move, penetrate the push hole 301 and push the bottom rivet into the conduit 7. When the front end of the rivet rod moves between multiple elastic plates 9, under the action of the clamping force of the elastic plates 9, the rivet rod automatically centers and aligns with the rivet hole. Finally, the rivet rod passes through the rivet hole, penetrates the folded edge and angle code of the aluminum veneer, and the rivet head is close to the outside of the folded edge of the aluminum veneer. The pressure head 8 presses the rivet head against the outside of the folded edge of the aluminum veneer, and then the simultaneous riveting and welding operations can be carried out.

[0036] When riveting and welding are performed simultaneously, the third cylinder 33 is extended so that the top iron 34 contacts the end of the rivet rod. At the same time, the output end of the laser welding device 10 is aligned with the gap at the corner of the aluminum plate. The third cylinder 33 is extended so that the top iron 34 moves close to the pressure head 8. Under the action of the extrusion force, the end of the rivet rod forms a pier head, completing the riveting. When the third cylinder 33 is extended, the fourth cylinder 14 is extended, and the laser welding device 10 is started to weld the corner gap of the aluminum plate, thereby achieving the synchronous completion of the welding operation.

[0037] After the riveting and welding operations are completed, the first cylinder 6, the third cylinder 33 and the fourth cylinder 14 retract, causing the pressure head 8, the top iron 34 and the laser welding device 10 to reset. After the first cylinder 6 is separated from the push hole 301, the rivet falls, and the rivet on the bottom side is aligned with the push hole 301, preparing for the next riveting. Then the four second cylinders 20 extend, causing the truss 5 to drive all the first risers 2 fixed thereto to move upward. Since the bottom corner bracket is fastened to the aluminum single plate by rivets, when the first riser 2 moves upward, it compresses the clamping plate 17, and the clamping plate 17 compresses the spring 18. Finally, the riveted corner bracket is separated from the two clamping plates 17. Then the clamping plate 17 is reset under the elastic force of multiple springs 18, sealing the unriveted corner brackets in the first riser 2. The bottom corner bracket moves downward under the action of gravity and falls on the upper side of the two clamping plates 17, preparing for the next riveting.

[0038] After the separation is completed, the first motor 26 and the second motor 40 are started to release the restrictions on the assembled aluminum veneer, drive the pressure plate 19 to move upward, and then move the welded and riveted aluminum veneer out of the upper side of the base 1, and place the next aluminum veneer to be assembled on the base 1 to carry out the next cycle operation.

[0039] The riveting and welding of the aluminum veneer are completed simultaneously in the above manner.

[0040] With the cooperation of the welding mechanism and the riveting mechanism, the welding of the corner gaps of the aluminum veneer and the riveting of the corner codes can be completed simultaneously, shortening the operation cycle and improving efficiency.

[0041] The extrusion stress of the rivet causes the aluminum veneer to plastically deform. Since riveting and welding are carried out simultaneously, the welding area is in a hot melt state during deformation, which can adapt to the extrusion plastic deformation and then solidify into an integrated shape, thereby eliminating the influence of extrusion deformation on welding contact, avoiding stress in the welding area, and ensuring welding quality.

[0042] With the collaboration of the riveting mechanism and the jig mechanism, the aluminum panel, angle brackets and rivets can be automatically aligned, thereby ensuring the accuracy of assembly. The rivets and angle brackets are automatically transported to further improve assembly efficiency.
