Description

Technical Field

[0001] This invention relates to the field of radiator welding equipment technology, specifically a laser welding device for steel radiators. Background Technology

[0002] Steel radiators (i.e., heating radiators) are widely used in heating systems of residential, commercial, and industrial buildings due to their advantages such as high structural strength, excellent pressure resistance, stable heat dissipation, and long service life. In the manufacturing process of steel radiators, the circumferential welding process at the joint between the workpiece end and the pipe is the core processing step. The quality of the welding, the uniformity of the weld, and the sealing performance directly determine the finished product quality and operational stability of the steel radiator.

[0003] Currently, existing steel radiator welding equipment still faces the following problems in practical production applications: First, although some existing welding equipment has the function of automatically transferring the material to the workstation during the loading process, operators still need to manually place each piece to the replenishment storage position and start welding one piece at a time. After each piece is processed, manual replenishment and start-stop operations must be repeated, making it impossible to achieve automatic continuous processing after batch replenishment. This is cumbersome, time-consuming, labor-intensive, and results in high labor costs. Second, the replenishment storage position of some existing welding equipment is adjacent to the welding operation area. Workers need to frequently approach the welding danger zone to replenish materials during equipment operation, making it impossible to complete replenishment in a safe area outside the equipment, posing a safety hazard. Third, the clamping fixture structure of some existing double-end welding equipment for radiators has limited adaptability. Adjusting the clamping distance for steel radiators of different lengths and specifications is inconvenient and makes it difficult to adapt to the processing needs of multiple workpiece specifications.

Position; A connecting arm 1209 is installed on the side of the connecting frame 1208 facing the feeding semi-enclosed screw module 801. The connecting arm 1209 extends to carry the welding execution component; A data panel 1210 is provided on the side of the connecting arm 1209 near the front feed port 3.

The laser welding head 1211 outputs a laser beam to complete the precise laser welding operation of the steel radiator; The workbench 2 is equipped with a main unit cabinet 13 on the side near the front feed port 3. The main unit cabinet 13 is used to centrally place the control host and laser welding host equipment, and plays a role in protection, dust prevention and neat wiring. A support plate 14 is provided on one side of the front feed port 3 on the protective housing 1. A control panel 15 is provided on the support plate 14. The support plate 14 provides stable support for the control panel 15. The control panel 15 is used for setting the parameters of the whole machine, controlling the start and stop and adjusting the program. A matching protective partition 16 is installed on the rear discharge port 4. The protective partition 16 can block welding fumes and light from leaking out when the equipment is stopped, and at the same time prevent external debris from entering the equipment. The rear of the protective housing 1 is equipped with a water cooler 17 and an argon gas cylinder 18 on one side of the rear discharge port 4. The water cooler 17 provides circulating water cooling for the laser welding head 1211 to prevent high temperature damage to the equipment. The argon gas cylinder 18 provides welding shielding gas to improve the welding quality and prevent weld oxidation. The rear of the protective housing 1 is provided with a pipe wiring connection hole 19, which facilitates the neat installation of water cooling pipes, gas pipes and wiring, and makes equipment installation and subsequent maintenance easier.

[0023] The principle and usage process of this invention: Before starting the equipment, the operator first opens the matching protective partition 16 at the rear discharge port 4 and sets up a workpiece discharge receiving device at the rear discharge port 4. Through the pipe wiring connection hole 19 at the rear of the protective housing 1, the water chiller 17 is connected to the laser welding main equipment inside the laser host mounting cabinet 13. At the same time, the argon gas cylinder 18 is connected to the welding station of the equipment to complete the heat dissipation, gas supply and power-on preparation work before starting the equipment. Subsequently, the operator pre-enters process parameters such as the workpiece length, end specifications, and welding position of the steel radiator to be processed through the control panel 15. The equipment calculates and matches the corresponding station spacing parameters based on the entered parameters, and starts the displacement drive mechanism 7 to complete the dual-station spacing adjustment operation. The displacement drive mechanism 7 operates through the transverse semi-enclosed screw module 703, which drives the movable side mounting base plate 6 to precisely move laterally through the connecting frame 704, while the fixed side mounting base plate 6 remains fixed. The spacing between the two sets of mounting base plates 6 is adjusted by unilateral displacement, so that the dual stations precisely match the current workpiece processing dimensions. After the workstation adjustment is completed, the telescopic feeding mechanism 9 is activated. The extension cylinder 903 extends slowly outward in advance, driving the connecting piece 904 and the L-shaped placement plate 905 through the front feed port 3 to the outside of the equipment, facilitating workpiece loading and reducing the safety hazard of personnel's hands approaching the inside of the equipment. The two ends of the steel radiator workpiece to be processed are placed stably on a pair of L-shaped placement plates 905. After placement, the extension cylinder 903 retracts, driving the workpiece to move horizontally to the preset waiting position inside the equipment, completing the safe feeding of the workpiece. After the workpiece is in place, the moving feeding mechanism 8 is activated. The semi-enclosed feeding screw module 801 drives the mounting plate frame 803, lifting cylinder 804, and top plate 805 to move laterally as a whole through the connecting frame 802. The top plate 805 moves precisely to directly below the L-shaped placement plate 905. At this time, the lifting cylinder 804 is in the reset and retracted state. Then, the lifting cylinder 804 extends, driving the top plate 805 to lift the workpiece upwards. The positioning groove 806 on the top plate 805 precisely limits the steel radiator. After positioning is completed, the piston rod of the lifting cylinder 804 is locked, and the semi-enclosed feeding screw module 801 is driven again to smoothly transfer the workpiece to the preset position between the electric grippers 1104 of the two rotating clamping mechanisms 11. After the workpiece is moved into place, the transverse semi-enclosed screw module 703 of the displacement drive mechanism 7 operates, driving the movable mounting base plate 6 to move closer to the fixed side, so that both ends of the workpiece are precisely embedded within the clamping range of the electric grippers 1104 on both sides. At this time, the rotary clamping mechanism 11 is in the reset state, and the electric grippers 1104 are in the horizontally open state. Subsequently, the equipment controls the electric grippers 1104 to close according to the preset workpiece end parameters, firmly clamping and fixing the two ends of the steel radiator. After clamping is completed, the lifting cylinder 804 retracts and resets, completely detaching from the bottom of the workpiece, avoiding structural interference during subsequent rotational welding. After the workpiece is clamped in place, welding parameters are preset via the control panel 15. The multi-axis laser welding mechanism 12 then initiates multi-axis linkage adjustment. The X-axis semi-enclosed lead screw module 1201, in conjunction with the X-axis semi-enclosed auxiliary module 1202, achieves precise lateral displacement; the Y-axis semi-enclosed lead screw module 1205 achieves longitudinal position adjustment; and the Z-axis semi-enclosed lead screw module 1207 completes fine-tuning of the welding height. The three-axis linkage precisely aligns the laser welding head 1211 with the weld seam on the workpiece. Simultaneously, the argon gas cylinder 18 continuously outputs protective gas to prevent weld oxidation. During the welding process, the synchronous servo motor 1103 drives the rotary mounting base 1102 to rotate the electric gripper 1104 and the workpiece. The laser welding head 1211 outputs a laser beam, which, in conjunction with the 360° rotation of the workpiece, completes precise circumferential welding of the steel radiator. Welding parameters and equipment operating status can be observed in real time via the data panel 1210. After the workpiece welding is completed, the synchronous servo motor 1103 rotates the electric gripper 1104 to a horizontal position and then stops. The moving feeding mechanism 8 operates again, and the feeding semi-enclosed screw module 801 drives the top plate 805 to move directly below the workpiece. The lifting cylinder 804 extends and securely supports the bottom of the welded workpiece through the positioning groove 806. The electric gripper 1104 opens and releases the workpiece. The displacement drive mechanism 7 drives the transverse semi-enclosed screw module 703 to operate again, causing the movable side mounting base plate 6 to move outward, so that the electric grippers 1104 on both sides completely disengage from the end of the workpiece, allowing the workpiece to be completely removed from the fixture.

[0024] After the workpiece is completely detached from the clamp, the lifting cylinder 804 raises, completely separating the workpiece from the gripper structure and placing it above the inclined discharge plate 1002. Then, the semi-enclosed feeding screw module 801 drives the workpiece to the mounting plate 1001 of the inclined discharge mechanism 10, at which point the workpiece is directly above the inclined discharge plate 1002. The lifting cylinder 804 retracts, and the workpiece, having lost its support, falls smoothly onto the surface of the inclined discharge plate 1002. Relying on the inclined structure of the plate, it automatically slides towards the rear discharge port 4 under its own weight and is discharged, completing the fully automatic discharge operation.

[0025] After a single workpiece is processed, all mechanisms automatically reset to their initial state, and the above feeding, positioning, clamping, welding, and unloading processes can be repeated to achieve batch continuous automated welding processing of steel radiators.
