[0050] It should be noted that all cylinders and motor surfaces are provided with high temperature resistant protective sleeves or protective covers.

[0051] Working principle: First, before welding, place the condenser tube from top to bottom in sequence on the condenser tube positioning assembly 2, that is, first place the condenser tube in the placement groove of the limit seat 1 52 on the first group of single cylinder positioning assembly 5, and the cylinder 1 511 starts to extend, so that the pressure rod 1 513 rotates counterclockwise around the connection with the connecting rod 1 514 pin, and the connecting rod 1 514 rotates counterclockwise around the connection with the connecting seat 1 512 pin, so that the pressure block 3 53 fixes the condenser tube to be welded in the limit seat 1 52, achieving the effect of fixed limit. The cylinder 2 611 of the double cylinder assembly 1 61 starts to extend, and the position of the end plate 1 is adjusted so that the baffle 1 614 contacts or is about to contact the condenser to be welded. The cylinder 1 511 of the cylinder drive assembly 51 starts to extend, so that the end of the L-shaped rod 612 on the pressure rod 1 513 presses down the baffle 1 614. After the baffle 1 614 is deformed, the right side rises, so that the right side of the baffle 1 614 is more closely fitted to the condenser to be welded. The cylinder 3 621 on the double cylinder assembly 2 62 starts to contract, so that the baffle 2 62 4 is in contact with or about to contact the condenser to be welded, the cylinder 1 511 of the cylinder driving assembly 51 starts to extend, so that the pressing rod 622 on the pressing rod 1 513 presses against the baffle 2 624, so that the left side of the baffle 2 624 is more closely fitted to the condenser to be welded; the limiting connecting block 72 on the adaptive positioning assembly 1 7 rotates according to the inclination angle of the condenser, and the cylinder 1 511 of the cylinder driving assembly 51 starts to extend, so that the pressing block 1 73 on the pressing rod 1 513 presses the condenser to prevent the condenser from sliding and rotating; Two groups of single-cylinder positioning assemblies 5 fix the condenser in position; finally, the motor 1 632 of the three-cylinder assembly 63 starts to rotate, and drives the rotating shaft 1 to rotate through the gear transmission, so as to adjust the angle of the support seat 3 634, and then the cylinder 4 631 starts to extend, driving the end plate 3 to move upward, so that the bottom of the condenser to be welded fits the limiting seat 2 636, and finally the cylinder 1 511 of the cylinder drive assembly 51 starts to extend, so that the pressure claw 637 on the pressure rod 1 513 limits the position of the bottom of the condenser to prevent it from slipping.

[0052] Afterwards, to fix the connecting piece before welding, first, according to the length of the connecting piece or the welding range, control the motor 4 86 on the driving assembly 8 to start, drive the bidirectional screw to rotate, drive the sliding block 85 to move toward or relative to each other on the slide rail 84, adjust the spacing between the two sets of adaptive positioning components 2 9, and then control the cylinder 1 511 of the cylinder driving assembly 51 on the adaptive positioning component 2 9 to start and extend, so that the pressure block 2 92 on the pressure rod 1 513 presses the connecting piece. Since the pressure block 2 92 is composed of a rectangular pressure block and an L-shaped pressure block, when pressing, the L-shaped pressure block is located at the top corner or bottom below and contacts the connecting piece, pressing the connecting piece, and at the same time, the bottom of the rectangular pressure block contacts the top of the sliding frame 94 on the right side, restricting the position of the sliding frame 94 so that it no longer moves, thereby fixing the position of the connecting piece.

[0053] Then, during welding, the motor 2 82 on the driving assembly 8 is started as needed, and the transmission is connected through gears and chains to drive the slide plate 81 to slide up and down in the slide groove. The motor 3 83 is started, and the shaft 2 is driven to rotate through gear transmission, thereby driving the slide rail 84 to rotate, which conditions the welding position and welding angle.

[0054] Welding fixing method 1: The condenser positioning component 2 fixes the special-shaped condenser, the adaptive positioning component 2 9 is used to fix the connecting parts, the driving component 8 controls the up and down positions of the slide plate 81 and the rotation angle of the slide rail 84, and when the angle sensor 2 87 detects that the rotation angle of the slide rail 84 reaches the set angle, it controls the welding robot 4 to weld the connecting part.

[0055] Welding fixing method two: The condenser positioning component 2 only uses the single cylinder positioning component 5 close to the connector positioning component 3 to fix the short and straight condenser. The adaptive positioning component 2 9 is used to fix the connector. When the driving component 8 controls the up and down positions of the slide plate 81 and the rotation angle of the slide rail 84 to the set angle, the welding robot 4 is controlled to weld the connecting part. At this time, the single cylinder positioning component 5 close to the connector positioning component 3 is repeatedly used to fix the short and straight condenser, and the driving component 8 is controlled to adjust the up and down positions of the slide plate 81 and the rotation angle of the slide rail 84. The condenser can be welded continuously and equidistantly along the length of the connector, thereby improving the welding efficiency.

[0056] Welding fixing method three: the single cylinder positioning component 5, double cylinder component one 61, double cylinder component two 62 and adaptive positioning component one 7 in the condenser positioning component 2 are used to fix the special-shaped condenser, and the three cylinder component 63 is used to fix the connecting parts. The motor one 632 is controlled to start rotating, driving the support seat three 634 to rotate. When the angle sensor one 633 detects that the rotation angle of the support seat three 634 is consistent with the angle of the lower part of the condenser, it stops, and then the cylinder four 631 is controlled to start extending and dock with the bottom of the condenser, and the welding robot 4 welds the connecting parts.

[0057] It should be noted that when only one group of welding robots 4 is used, welding fixation method 2 and welding fixation method 3 can be performed alternately to save loading time; if more than one group of welding robots 4 is used, welding fixation method 2 and welding fixation method 3 can be performed independently without affecting each other, and welding fixation method 1 and welding fixation method 3 can also be performed simultaneously without affecting each other, thereby improving welding efficiency.

[0058] Finally, after welding is completed, the time module starts timing. When the set time is reached, the temperature sensor 10 fixed on the welding robot 4 detects the weld temperature; if the weld temperature does not exceed the cooling temperature setting value, the cooling temperature meets the material unloading requirements and material unloading can be carried out; if the weld temperature is higher than the cooling temperature setting value, the weld cooling time is extended. When the weld temperature is higher than twice the cooling temperature setting value, the cooling time is extended to the original cooling time. When the weld temperature is not higher than twice the temperature setting value, the cooling time is extended to half of the original cooling time to avoid incomplete cooling of the weld, low hardness of the connection, deformation due to bumps during unloading, or scalding of the staff during unloading due to high temperature.
