Description

Technical Field

[0001] The invention relates to the technical field of heat exchangers, and is specifically disclosed as an automated production line for heat exchanger processing. Background Art

[0002] In the U-tube welding process of the heat exchanger, most of the current welding machines adopt an assembly line welding method, that is, a number of long U-tubes equipped with fin groups to be welded are placed on the assembly line, and the products are always moving with the assembly line. First, a single short U-tube is grabbed by a manipulator and placed in the pipe mouth at the upper end of the long U-tube accordingly. This is repeated until all the long U-tubes are stuck with short U-tubes. Then the welding work can be started, and the welded workpiece "flows" through the middle of the fire bar, thereby welding the long U-tube and the short U-tube together, thereby completing the assembly and welding of the heat exchanger components.

[0003] Since most heat exchanger components are equipped with a large number of long U-shaped tubes for heat dissipation, a corresponding number of short U-shaped tubes are required for assembly. However, during operation, the robot can only grab a short U-shaped tube for assembly one at a time, which has a low work efficiency. In addition, the position of the fire bar nozzle is fixed during this type of welding method. During the process of the workpiece "flowing" from the front end of the fire bar to the end of the fire bar, the temperature of the welding area is non-uniformly distributed, which can easily cause welding defects.

The threaded sleeve 507 carries the translation plate 505 and the sorting plate 501, moves along the guide column 511, and moves to the upper side of the heat exchanger assembly 10 installed on the bearing assembly 1 transported here. Then, the sorting plate 501 is pushed down by the cylinder 8, and the several short U-shaped tubes are assembled at the pipe mouths of the corresponding heat exchanger assembly 10. The air pump is closed to separate the several short U-shaped tubes from the U-shaped cavity 502, and then the sorting plate 501 returns to its original position to prepare for the next round of assembly work, so that the assembly of the short U-shaped tubes can be completed at one time, which greatly saves the time of the robot arm to grab each one for assembly.

[0069] The upper and lower ends of the rotating rod 601 are rotatably connected to the welding chamber 6, and a plurality of welding nozzles 602 are fixed on the rotating plate 604. The rotating plate 604 is fixedly connected to the rotating rod 601. The height of the rubber roller 603 is greater than the thickness of the rubber strip 103. The plurality of welding nozzles 602 rotate accordingly with the rotating rod 601 as the axis. The welding nozzles 602 are all facing the entrance of the welding chamber 6. The plurality of welding nozzles 602 are controlled to switch by the gas control box.

[0070] Specifically, the assembled heat exchanger assembly 10 enters from the entrance of the welding chamber 6, and the welding nozzles 602 are all directed toward the entrance of the welding chamber 6 (such as Figure 8 As shown), the gas control box is used to control the welding nozzle 602 to open for welding, and as the bearing assembly 1 slowly moves, the rubber strips 103 on both sides of the bearing assembly 1 contact the rubber rollers 603 on both sides, and through friction, the rubber rollers 603 and the rotating rod 601 are driven to rotate accordingly, and the rotating rod 601 drives the rotating plate 604, that is, the plurality of welding nozzles 602 to rotate accordingly, so that the plurality of welding nozzles 602 follow the movement of the heat exchanger assembly 10 and rotate the welding angle accordingly, so as to achieve the effect of always following the heat exchanger assembly 10 for welding, with better welding effect and more comprehensive welding angle, avoiding uneven welding when the welding head is fixed, and setting the length of the welding nozzles 602 at both ends arranged on the rotating plate 604 to be longer than the welding nozzle 602 in the middle part, so that when the welding angle follows the rotation of the heat exchanger assembly 10, the surrounding welding can be maintained, avoiding the welding nozzles 602 at both ends and the welding nozzles 602 in the middle side having different welding spacings on the heat exchanger assembly 10, resulting in uneven welding.

[0071] When heat exchanger assemblies 10 of different heights are transported and welded, the height position of the supporting assembly 1 is not fixed at this time, so the height of the rubber roller 603 is greater than the thickness of the rubber strip 103, so that the rubber strip 103 can still contact the rubber roller 603 at different heights, and has strong versatility.

[0072] And when the welded heat exchanger assembly 10 is moved out of the welding chamber 6, the staff can remove it and then return the supporting assembly 1 to the origin. At this time, when passing through the rubber roller 603, the rotating plate 604 and several welding nozzles 602 can be reset to facilitate the next welding.

[0073] The conveying track 3 is arranged to be connected end to end, and a torsion spring is arranged at the rotating position of the rotating rod 601 .

[0074] Preferably, the conveying track 3 can be arranged to be connected end to end, and other processing steps can be arranged on this conveying track 3, and then a torsion spring can be arranged on the rotating rod 601 so that it can automatically reset after welding, so that several groups of supporting components 1 can simultaneously drive multiple groups of heat exchanger components 10 for processing, thereby increasing production efficiency.
