[0019] 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.

[0020] like Figures 1-4 As shown, this utility model provides a five-station laser welding machine for shock absorber rings in electric vehicles, including a worktable 1. A five-station turntable 2 is rotatably mounted on the worktable 1. The five-station turntable 2 is driven to rotate by a drive mechanism. The five stations of the five-station turntable 2 are, in sequence, a loading station, a weld seam recognition station, a laser welding station, a laser marking station, and a unloading station. Each of the five stations of the five-station turntable 2 is equipped with a workpiece clamping mechanism for clamping the workpiece. On the worktable, a weld seam recognition mechanism, a laser welding mechanism, a laser marking mechanism, and a unloading mechanism are respectively arranged on the outer side of the weld seam recognition station, the laser welding station, the laser marking station, and the unloading station. The drive mechanism, the workpiece clamping mechanism, the weld seam recognition mechanism, the laser welding mechanism, the laser marking mechanism, and the unloading mechanism are all electrically connected to a control system. The control system controls the drive mechanism, the workpiece clamping mechanism, the weld seam recognition mechanism, the laser welding mechanism, the laser marking mechanism, and the unloading mechanism to work in a coordinated manner.

[0021] In use, the pre-formed pressure ring 3 is manually placed from the loading station onto the corresponding workpiece clamping mechanism on the five-station turntable 2. The workpiece clamping mechanism clamps the pressure ring 3, keeping the weld seam of the pressure ring 3 centered and facing upwards. Then, the five-station turntable 2 rotates under the drive mechanism, thus conveying the pressure ring 3 from the loading station to the weld seam identification station. The weld seam identification mechanism detects the weld seam position on the pressure ring 3 and transmits the weld seam position information to the control system. Then, the five-station turntable 2 continues to rotate, thus conveying the pressure ring 3 from the weld seam identification station to the laser welding station. The control system controls the laser welding mechanism to perform laser welding on the weld seam position of the pressure ring 3 according to the weld seam position information, so that the pressure ring 3... The two free ends are welded together, and then the five-station turntable 2 continues to rotate, thereby conveying the pressure ring 3 from the laser welding station to the laser marking station. The laser marking mechanism marks the outer wall of the pressure ring 3 to mark the production date, QR code, product number and other markings on the outer wall of the pressure ring 3. Then the five-station turntable 2 continues to rotate, thereby conveying the pressure ring 3 from the laser marking station to the unloading station. The unloading mechanism removes the pressure ring 3 from the workpiece clamping mechanism and puts it into the designated position, thereby completing the continuous operation of loading, identifying the weld position, laser welding, laser marking and unloading of the pressure ring 3. No manual handling is required, the labor intensity is low, the production efficiency is high, and the structure is simple, reducing the floor space and improving the site utilization rate.

[0022] Preferably, the laser welding mechanism and the laser marking mechanism are equipped with a suction nozzle 4, which is connected to a vacuum cleaner 5 via a suction pipe. The vacuum cleaner 5 is electrically connected to the control system. During the laser welding or laser marking process, the dust generated can be sucked into the vacuum cleaner 5 through the suction nozzle 4 for treatment.

[0023] Preferably, the five-station turntable 2 is provided with a multi-faceted cover 6, and five workpiece clamping mechanisms are circumferentially and evenly installed on the outer surface of the multi-faceted cover 6, with a reasonable layout. The driving mechanism includes a divider connected to the five-station turntable 2, and the divider is connected to a drive motor 7. The drive motor 7 and the divider cooperate to make the five-station turntable 2 rotate intermittently, realizing the switching of the five-station turntable 2 between the five stations. The workpiece clamping mechanism includes a rotating seat 8 rotatably installed on the outer surface of the multi-faceted cover 6. The rotating seat 8 is driven by a rotating motor to rotate. The rotating seat 8 is provided with a support column 9 for hanging the workpiece. A movable column 10 is provided on one side of the support column 9. The movable column 10 is driven by a clamping cylinder 11 to move closer to or away from the support column 9. The movable column 10 moves closer to the support column 9 to clamp the workpiece. In this embodiment, there are two movable columns 10 and two support columns 9. The support column 9 is located below the movable column 10. The drive motor 7, the rotating motor and the clamping cylinder 11 are controlled by the control system. In use, the pressure ring 3 is manually hung on the support column 9, with the rear side of the pressure ring 3 close to the rotating seat 8. Then, the clamping cylinder 11 drives the movable column 10 to approach the support column 9, thereby clamping the pressure ring 3. At this time, the weld on the pressure ring 3 is located between the two movable columns 10 and the weld is set at the top. The control system controls the laser welding mechanism to weld the weld on the outer side of the pressure ring 3 according to the weld position. The rotating motor drives the rotating seat 8 to rotate 180°, thereby flipping the pressure ring 3, that is, the weld on the inner side of the pressure ring 3 is set at the bottom. In this way, the laser welding mechanism can weld the weld on the inner side of the pressure ring, ensuring that the welding is in place. The pressure ring 3 can remain in this state until the laser marking station. The upper outer wall of the pressure ring 3 can be marked by the laser marking mechanism, which can avoid the weld seam. After the marking is completed, the rotating motor can drive the rotating seat 8 to reset, which facilitates subsequent unloading and loading. The clamping cylinder 11 drives the movable column 10 away from the support column 9, thereby releasing the pressure ring 3, and the pressure ring can be removed by the unloading mechanism.

[0024] Preferably, the weld seam recognition mechanism includes a weld seam recognition stand 12 mounted on the workbench 1. A weld seam recognition camera 13 is mounted on the stand 12. The camera 13 can accurately detect the weld seam position and transmit the position information to the control system, facilitating subsequent laser welding. The weld seam recognition camera can be raised and lowered relative to the weld seam recognition stand via a lifting mechanism, thus adapting to the recognition of weld seams on pressure rings of different sizes.

[0025] Preferably, the laser welding mechanism includes a laser welding XYZ module 14 mounted on the worktable 1 and a laser welding frame 15 mounted on the laser welding XYZ module 14. The laser welding frame 15 is equipped with a welding displacement sensor 16 and a laser galvanometer welding head 17. The laser welding XYZ module 14 can drive the laser welding frame 15 and its welding displacement sensor 16 and laser galvanometer welding head 17 to move in three directions: X-axis, Y-axis, and Z-axis. The welding displacement sensor 16 is used to detect the distance between the pressure ring 3 and the laser galvanometer welding head 17 to complete automatic height alignment, so as to facilitate the laser galvanometer welding head 17 to accurately weld the weld seam. It can adapt to the laser welding of pressure rings 3 of different sizes.

[0026] Preferably, the laser welding frame 17 is equipped with a welding detection device 18. The welding detection component is a prior art technology. It is used to detect the welding quality in real time during the welding process and to determine whether it is qualified. A laser power meter 19 is provided next to the laser welding mechanism. The laser 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.

[0027] Preferably, the laser marking mechanism includes a laser marking XYZ module 20 mounted on the worktable 1. The laser marking XYZ module 20 is equipped with a marking displacement sensor 21 and a laser marking head 22. The laser marking XYZ module 20 can drive the marking displacement sensor 21 and the laser marking head 22 to move in three directions: X-axis, Y-axis, and Z-axis. The marking displacement sensor 21 is used to detect the distance between the pressure ring 3 and the laser marking head 22, completing automatic height alignment to facilitate precise marking by the laser marking head 22. This mechanism can adapt to laser marking of pressure rings of different sizes.

[0028] Preferably, the unloading mechanism includes an unloading rack 23 mounted on the workbench 1. A first moving plate 24 is laterally slidable on the unloading rack 23.

The clamping cylinder 30 drives the clamping jaws 31 to clamp the pressure ring 3. The workpiece clamping mechanism releases the pressure ring 3. Then, through the cooperation of the first cylinder 25, the second cylinder 26 and the third cylinder 28, the clamping jaws 31 are moved to the designated position. When the pressure ring 3 is detected as a qualified product by the welding inspection device, it is transferred to the qualified product conveyor belt 33 and can be transported to the next station. When it is detected as a defective product, it is transferred to the defective product bin 32.

[0029] Preferably, the workbench 1 is equipped with a housing 34 that houses the five-station turntable 2, weld identification mechanism, laser welding mechanism, laser marking mechanism, and unloading mechanism, making it safer to use.
