[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] like Figures 1-4 As shown, this utility model provides an automated laser welding production line for shock absorber pressure rings for electric vehicles, including a steel strip feeder 1, a ring forming machine 2, a spot welding machine 3, a laser welding machine, a laser marking machine, a conveyor line 4, several robotic arms 5, and a central control console 6.

[0027] The steel strip feeder 1 is located on the feeding side of the coiling machine 2 and is used for rotating and installing the steel strip;

[0028] The ring forming machine 2 receives the steel strip conveyed from the steel strip feeder 1, rings the steel strip, and cuts it to form a ring-shaped preliminary compression ring. In this embodiment, the ring forming machine 2 is a five-axis ring forming machine.

[0029] The spot welding machine 3 is located on the discharge side of the ring forming machine 2 and performs pre-welding on the prototype pressure ring, thereby pre-welding the two free ends of the prototype pressure ring together.

[0030] The laser welding machine is located on one side of the spot welding machine 3 and performs laser welding on the prototype pressure ring, thereby welding the two free ends of the prototype pressure ring together to form the finished pressure ring.

[0031] The laser marking machine is located on one side of the laser welding machine and performs marking on the outer wall of the finished pressure ring.

[0032] The conveyor line 4 is located on one side of the laser marking machine and transports the finished pressure ring to the next process;

[0033] Several robotic arms 5 are distributed among the ring forming machine 2, the spot welding machine 3, the laser welding machine, the laser marking machine, and the assembly line 4, and sequentially transport the pressing rings to the spot welding machine 3, the laser welding machine, the laser marking machine, and the assembly line 4. In this embodiment, there are two robotic arms 5, one of which is located between the ring forming machine 2, the spot welding machine 3, and the laser welding machine, and the other is located between the laser welding machine, the laser marking machine, and the assembly line 4.

[0034] The main control console 6 is electrically connected to the ring forming machine 2, the spot welding machine 3, the laser welding machine, the laser marking machine, and several robotic arms 5, and controls the ring forming machine 2, the spot welding machine 3, the laser welding machine, the laser marking machine, and several robotic arms 5 to work in coordination.

[0035] The steel strip feeder 1, five-axis coiling machine, spot welding machine 3, conveyor line 4, and robotic arm 5 of this utility model are existing technologies and will not be described in detail here. During operation, a bundle of steel strip is manually placed onto the steel strip feeder 1. The bundle of steel strip can rotate around the feeder 1 according to the processing requirements. The central control console 6 issues commands to the coiling machine 2, spot welding machine 3, laser welding machine, and laser marking machine based on the size of the pressure ring. Each piece of equipment switches to the appropriate operating state according to the size of the pressure ring. First, the steel strip enters the coiling machine 2 from the feed end. The coiling machine 2, according to the instructions from the control panel 6, coils and cuts the steel strip to form a preliminary ring shape. Then, the robot arm 5 picks up the preliminary ring from the coiling machine 2 and transfers it to the spot welding machine 3. The spot welding machine 3, according to the instructions from the control panel, performs pre-welding on the preliminary ring, pre-welding the two free ends together to facilitate subsequent welding. Next, the robot arm 5 picks up the preliminary ring from the spot welding machine 3 and transfers it to the laser welding machine. The laser welding machine performs laser welding on the preliminary ring, welding the two free ends together to form the finished ring. Then, the robot arm 5 picks up the finished ring from the laser welding machine and transfers it to the laser marking machine. The laser marking machine marks the outer wall of the finished ring. Finally, the robot arm 5 picks up the finished ring and transfers it to the conveyor line 4, which transports the finished ring to the next process for further processing. Using the above structure, automated production of pressure rings can be completed, including feeding, ring forming, cutting, pre-welding, laser welding, laser marking, and assembly line output. No manual handling is required, resulting in low labor intensity and high production efficiency.

[0036] Preferably, the laser welding machine includes a worktable 7, on which a welding clamping assembly 8 for holding the pressure ring is mounted. Above the welding clamping assembly 8 is a galvanometer scanning laser head 9 for laser welding the pressure ring. The galvanometer scanning laser head 9 is connected to a power meter 19. A laser rangefinder and a vision scanner are also located next to the galvanometer scanning laser head 9. The power meter 19 is used to measure whether the laser power drops when the machine is turned on, so as to adjust the laser power in a timely manner. The laser rangefinder and vision scanner can perform visual positioning and automatic height alignment to identify the welding position for precise welding. The galvanometer scanning laser head 9 is mounted on the worktable 7 via a moving system. The welding clamping assembly 8 clamps and fixes the pressure ring. Driven by the moving system, the galvanometer scanning laser head 9 can move along multiple axes to perform laser welding on the prototype pressure ring.

[0037] Preferably, the laser marking machine includes a marking clamping assembly 10 mounted on the worktable 7 for clamping the pressure ring. Above the marking clamping assembly 10 is a laser marking head 11 for laser marking the pressure ring. Next to the laser marking head 11 are a laser rangefinder and a vision scanner. The laser rangefinder and vision scanner can perform visual positioning and automatic height alignment to identify the marking position for accurate marking. The laser marking head 11 is mounted on the worktable 7 via a moving system. The marking clamping assembly 10 clamps and fixes the pressure ring. Driven by the moving system, the laser marking head 11 can move along multiple axes to laser mark the outer wall of the finished pressure ring.

[0038] Preferably, both the welding clamping assembly 8 and the marking clamping assembly 10 include a clamping back plate 12. Front clamping blocks 13 are provided on the front of both sides of the clamping back plate 12. The front clamping blocks 13 are driven by the front clamping cylinder 14 to move back and forth. The front clamping blocks 13 move backward to clamp the pressure ring between the front clamping blocks 13 and the clamping back plate 12. A support column 15 for holding the pressure ring is provided on the upper front side of the clamping back plate 12. A movable column 16 is provided above the support column 15. The movable column 16 is driven by the upper clamping cylinder 17 to move up and down. The movable column 16 moves down to clamp the pressure ring between the support column 15 and the movable column 16. In use, the front clamping block 13 moves forward and is positioned in front of the front end of the support column 15, thus creating space between the front end of the support column 15 and the front clamping block 13 for the pressure ring to be inserted. The robot arm 5 hangs the pressure ring on the support column 15, with the front clamping block 13 positioned in front of the pressure ring. The front clamping cylinder 14 drives the front clamping block 13 to move backward, causing the pressure ring to move backward along the support column 15 and clamp between the front clamping block 13 and the clamping back plate 12. Then, the upper clamping cylinder 17 drives the movable column 16. The pressure ring is moved downwards, clamping it between the support column 15 and the movable column 16. That is, the inner wall of the upper end of the pressure ring contacts the support column 15, and the outer wall of the upper end of the pressure ring contacts the movable column 16. The pressure ring can then be processed by the galvanometer scanning laser head 9 or the laser marking head 11. After processing, the front clamping cylinder 14 drives the front clamping block 13 to move forward, and the upper clamping cylinder 17 drives the movable column 16 to move upward, thereby releasing the pressure ring. The pressure ring can then be removed by the robot arm 5.

[0039] Preferably, a welding detection component 20 is also provided next to the laser welding machine. The welding detection component 20 is existing technology and is used to detect the welding quality in real time during the welding process.

[0040] Preferably, the laser welding machine is equipped with an air blowing assembly at the rear. The air blowing assembly is existing technology and prevents the weld joint from oxidizing during welding by outputting inert gas.

[0041] Preferably, a protective railing 18 is also included, which encloses the ring forming machine 2, the spot welding machine 3, the laser welding machine, the laser marking machine, and several robotic arms 5, providing a safety protection function.
