Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of welding equipment, and particularly relates to a new energy automobile aluminum alloy radiator welding device. BACKGROUND

[0002] With the rapid development of the new energy automobile industry, an efficient and reliable thermal management system has become one of the key factors to improve its performance. As one of the core components of the thermal management system, the aluminum alloy radiator has been widely used in new energy automobiles due to its lightweight, high thermal conductivity and good corrosion resistance. In order to meet the higher requirement of heat dissipation efficiency, the modern aluminum alloy radiator is usually designed as a complex structure with a large number of small heat dissipation holes. These heat dissipation holes can significantly increase the heat dissipation area, thereby improving the overall heat dissipation performance.

[0003] Specifically, the aluminum alloy radiator of the new energy automobile is usually composed of multiple parts, including the heat dissipation fins, the water tank (or called core body), and the covers at both ends. During the manufacturing process, the core body and the covers at both ends need to be precisely fixed by laser welding technology to ensure that the radiator can work normally and effectively dissipate heat during the operation of the vehicle. As an advanced connection technology, laser welding has the advantages of energy concentration, fast welding speed, and small heat-affected zone, and is particularly suitable for the fine processing of aluminum alloy materials.

[0004] Although the existing laser welding equipment can effectively laser weld the core body and the covers at both ends, the existing laser welding equipment lacks an effective mechanism to cover and protect the heat dissipation holes on the core body. During the laser welding process of the aluminum alloy radiator, a certain amount of metal oxides or incomplete fusion residues, so-called "welding slag", may be produced after the high-temperature molten metal cools and solidifies. Since the core body is distributed with a large number of heat dissipation holes, and these heat dissipation holes are usually small in diameter and densely arranged, the welding slag is easy to enter the inside of the heat dissipation holes during the welding process, resulting in the following problems:

[0005] 1. Reduced heat dissipation performance: The welding slag clogging the heat dissipation holes will reduce the effective heat dissipation area, hinder the air circulation, and reduce the overall heat dissipation efficiency.

[0006] 2. Damaged structural strength: The presence of welding slag may change the internal stress distribution of the radiator, leading to a decrease in local structural strength and increasing the risk of cracking or failure in long-term use.

[0007] 3. Difficult assembly: In the subsequent assembly process, the welding slag in the heat dissipation holes may interfere with other components, affecting the assembly accuracy and efficiency. SUMMARY

[0034] Firstly, the core body 10 and the cover 11 at both ends are butt-jointed together, and then the butt-jointed core body 10 and cover 11 are conveyed to the right on the belt conveyor 2 through the conveying equipment, and then the belt conveyor 2 is controlled to work to convey the core body 10 and the cover 11 to the right to the welding station. At the same time, the driving motor 66 is controlled to work to drive the chain transmission assembly 61 to rotate the connecting plate 62, so as to rotate the cover plate 64 to the upper side of the core body 10, and then the electric push rod 65 is controlled to drive the cover plate 64 to move downward and cover the core body 10. The cover plate 64 moves downward to drive the positioning plate 67 to move downward, and since the lower portion of the positioning plate 67 is outwardly bent, the downward movement of the positioning plate 67 can push the core body 10 to move in the left-right direction to be centered, so that the core body 10 is completely aligned with the cover plate 64, and the core body 10 can be positioned by the positioning plate 67 and the cover plate 64 to avoid displacement of the core body 10 in the subsequent welding process.

[0035] Then the XZ axis moving platform 3 drives the stepper motor 31 to move the eccentric disc 4 to the right, so that the laser welding head 5 is moved along the top of the core 10 and the cover 11 to the right through the mounting plate 41, and laser welding is performed on the top of the core 10 and the cover 11. When the laser welding head 5 moves to the right upper corner of the core 10 and the cover 11, the stepper motor 31 is controlled to drive the eccentric disc 4 to rotate, so that the laser welding head 5 is rotated along the right upper corner of the core 10 and the cover 11 through the mounting plate 41, and laser welding is performed on the corner of the core 10 and the cover 11 (see Figure 7 ). Then the XZ axis moving platform 3 drives the stepper motor 31 to move down, so that the laser welding head 5 is moved along the right side of the core 10 and the cover 11 to the down, and laser welding is performed on the right side of the core 10 and the cover 11. When the laser welding head 5 moves to the right lower corner of the core 10 and the cover 11, the stepper motor 31 is controlled to drive the eccentric disc 4 to rotate, so that the laser welding head 5 is rotated along the right lower corner of the core 10 and the cover 11, and laser welding is performed on the corner. The laser welding head 5 is rotated to the lower side of the core 10 and the cover 11 (see Figure 8 ), and then the XZ axis moving platform 3 drives the stepper motor 31 to move to the left, so that the laser welding head 5 is moved along the bottom of the core 10 and the cover 11 to the left, and laser welding is performed on the bottom of the core 10 and the cover 11. When the laser welding head 5 moves to the left lower corner of the core 10 and the cover 11, the stepper motor 31 is controlled to drive the eccentric disc 4 to rotate, so that the laser welding head 5 is rotated along the left lower corner of the core 10 and the cover 11, and laser welding is performed on the corner. Then the XZ axis moving platform 3 drives the stepper motor 31 to move up, so that the laser welding head 5 is moved along the left side of the core 10 and the cover 11 to the up, and laser welding is performed on the left side of the core 10 and the cover 11. When the laser welding head 5 moves to the left upper corner of the core 10 and the cover 11, the stepper motor 31 is controlled to drive the eccentric disc 4 to rotate, so that the laser welding head 5 is rotated along the left upper corner of the core 10 and the cover 11, and laser welding is performed on the corner. Through the above operation, the whole radiator is fully welded.

[0036] After the whole radiator is welded, the belt conveyor 2 is controlled to continue conveying the radiator to the right, and at the same time, the driving motor 66 is controlled to work to drive the chain transmission assembly 61 to drive the connecting plate 62 to rotate, so that the cover plate 64 moves to the right together with the radiator, thereby keeping effective protection of the radiator holes and avoiding the welding slag from entering the radiator holes in the subsequent welding slag cleaning process. During the movement of the radiator to the right, the top and bottom of the radiator are in contact with the upper and lower cleaning pieces 73 on the fixed plate 71 respectively, and the electric rotating rod 72 on the fixed plate 71 is controlled to work to drive the cleaning pieces 73 on the fixed plate 71 to rotate, and the rotation of the upper and lower cleaning pieces 73 on the fixed plate 71 can clean the welding slag on the top and bottom of the radiator. When the radiator moves to the right to align with the U-shaped lifting plate 75, the screw rod motor 76 is controlled to work to drive the lifting plate 75 to drive the electric rotating rod 72 and the cleaning piece 73 thereon to reciprocate up and down. The left and right cleaning pieces 73 on the lifting plate 75 are in contact with the left and right side walls of the radiator respectively when they are lifted, and the electric rotating rod 72 on the lifting plate 75 is controlled to work to drive the cleaning pieces 73 on the lifting plate 75 to rotate, and the lifting and rotation of the left and right cleaning pieces 73 on the lifting plate 75 can clean the welding slag on the left and right side walls of the radiator. After the welding slag is cleaned, the electric push rod 65 is controlled to drive the cover plate 64 to move upward and separate from the radiator.

[0037] Referring to Figure 4 , the fixed plate 71 and the lifting plate 75 are both connected with two covers 81, the cover 81 and the cleaning piece 73 are one-to-one corresponding, the cover 81 is covered outside the corresponding cleaning piece 73, and the cover 81 is connected with a suction pipe 82.

[0039] Referring to Figure 3 and Figure 5 , the XZ-axis moving platform 3 is provided with a pressing mechanism, the pressing mechanism is used for pressing the lid 11 to be fixed on the core body 10, and the pressing mechanism comprises a connecting plate 90 connected to the XZ-axis moving platform 3, the connecting plate 90 is located on the lower side of the stepping motor 31, the connecting plate 90 is connected with two left and right telescopic rods two 91, the two telescopic rods two 91 are connected with an L-shaped movable plate 92, the inner bottom surface of the L-shaped movable plate 92 is rotatably connected with a pressure roller 93 from left to right, the pressure roller 93 is used for pressing the lid 11 to be fixed on the core body 10, and a pneumatic cylinder 94 is installed on the connecting plate 90 and located between the two telescopic rods two 91, the piston rod of the pneumatic cylinder 94 is connected with the movable plate 92, so as to drive the movable plate 92 to reciprocate forward and backward.

[0040] When the core 10 and the cover 11 to be welded together are conveyed to the right to the welding station, the control cylinder 94 drives the movable plate 92 to move the pressing roller 93 to the direction close to the cover 11, the cover 11 can be pressed and fixed on the core 10 by the pressing roller 93, so as to improve the stability of the cover 11 and the core 10, to avoid the cover 11 falling off from the core 10 during the welding process, so as to ensure the operation of welding the core 10 and the cover 11 together. When the XZ-axis moving platform 3 drives the laser welding head 5 to move to the right, the connecting plate 90, the telescopic rod 91, the movable plate 92, the pressing roller 93 and the cylinder 94 move to the right together, the pressing roller 93 moves and rolls along the cover 11 to avoid hard friction with the cover 11, which can cause damage to the cover 11. Before the control step motor 31 drives the eccentric disc 4 to rotate, the control cylinder 94 drives the movable plate 92 to move the pressing roller 93 to reset, to avoid the eccentric disc 4, and avoid hindering the subsequent rotation of the eccentric disc 4.
