The lower positioning roller 13 is provided with an annular groove 15 for lateral positioning of the profile, and the upper positioning roller 14 can be vertically raised and lowered.

[0033] In this embodiment, the bases on the feeding straightening roller assembly 5 and the discharging straightening roller assembly 6 that support the lower positioning roller 13 can be synchronously driven to rise and fall by the worm gear assembly 16.

[0034] In this embodiment, the welding seat 1 is further provided with one or more sets of auxiliary straightening roller assemblies 17 at its discharge end and feed end, which are used in conjunction with the feed straightening roller assembly 5 and the discharge straightening roller assembly 6.

[0035] In this embodiment, the feeding top roller assembly 8 and the discharging top roller assembly 11 have the same structure, including a support frame 18. The support frame 18 can be vertically lifted and lowered. A lower support roller 19 is installed on the top of the support frame 18. A lateral positioning seat 20 is installed on one side of the support frame 18. The lateral positioning seat 20 includes a positioning rod 20a that can move laterally relative to the support frame 18.

[0036] In this embodiment, the pushing component 7 and the pulling component 12 have the same structure, including a sliding seat 21. A lateral positioning plate 22 and a base plate 23 are fixed on the sliding seat 21. A pressing plate 24 that can be vertically lifted and lowered is provided parallel above the base plate 23. A second lateral positioning seat 25 is installed on one side of the sliding seat 21. The second lateral positioning seat 25 includes a second positioning rod 25a that can move laterally relative to the first lateral positioning seat 25.

[0037] In this embodiment, the alignment component 9 includes a mounting base 26, and the mounting base 26 is slidably provided with an elastic positioning plate 27 capable of vertical lifting on the side facing the feed top wheel assembly 8.

[0038] In this embodiment, the precise feeding component 10 includes a lower support roller 28 and an upper positioning roller 29 parallel to the lower support roller 28. The upper positioning roller 29 can be vertically raised and lowered. A lateral positioning seat 30 is installed on one side of the lower positioning roller 28.

[0039] In this embodiment, the feeding support frame 2 and the discharging support frame 3 are provided with guide rails that cooperate with the sliding seat 21, and the guide rails are provided with accordion-style protective covers 31.

[0040] Specifically, the power mechanism used to drive vertical lifting can adopt any suitable structural form such as a cylinder or a linear module. The welding module 4, the worm gear assembly 16 and the auxiliary straightening roller assembly 17 can all adopt existing technologies, which will not be elaborated here.

[0041] The working principle of this embodiment is as follows.

[0042] Step 1: The lower support roller 19 of the feed top roller assembly 8 is raised to a high position. The first workpiece is placed on the lower support roller 19 manually or by a robot, and the second workpiece is placed on the first workpiece.

[0043] Step 2: The side positioning seat 20 of the feed top roller assembly 8 clamps the two workpieces together, thus aligning them in the width direction.

[0044] Step 3: The pusher assembly 7 moves to its lateral positioning plate 22 to be close to the workpiece and clamps the workpiece by cooperating with the pressure plate 24 and the base plate 23, so that the workpiece remains stable in the width and height directions during the movement.

[0045] Step 4: The pusher assembly 7 moves to push the workpiece to the alignment assembly 9. During the pushing process, the feed top roller assembly 8 descends to avoid it, and the workpiece is aligned in the length direction by the positioning of the elastic positioning plate 27.

[0046] Step 5: Alignment component 9 descends to avoid obstacles, and pusher component 7 pushes the workpiece to feed precision component 10;

[0047] Step 6: The precision feeding assembly 10 clamps the workpiece and performs precise correction in the width and height directions before sending the workpiece to the feeding straightening roller assembly 5.

[0048] Step 7: The feeding and straightening roller assembly 5 clamps and pushes the workpiece to the welding module 4. During the pushing process, the height and width directions are corrected to ensure the accuracy and stability of the workpiece throughout the welding process.

[0049] Step 8: Under the control of the CNC system, welding module 4 performs laser welding on the workpiece to achieve mechanical positioning and guided welding, so as to meet the requirements of high efficiency and high precision processing.

[0050] Step 9: The discharge straightening roller assembly 6 clamps the welded workpiece again and corrects its height and width to prevent thermal deformation of the workpiece after high-temperature welding, and moves the workpiece to the discharge port;

[0051] Step 10: The material pulling assembly 12 moves to the discharge port of the discharge straightening roller assembly 6 and clamps the workpiece. During the material pulling process, the discharge top roller assembly 11 rises to clamp and support, and cooperates with the material pulling assembly 7 to take out the laser-welded workpiece.

[0052] Step 11: After the material pulling assembly 12 moves to the end and pulls the workpiece out completely, the clamping plate 24 of the material pulling assembly 12 and the lateral positioning seat 20 of the discharge top wheel assembly 11 release the workpiece, thus completing the material pulling operation.

[0053] Step 12: Manually or by robot, the laser-welded workpieces on the material pulling assembly are unloaded, while repeating steps one through eleven to achieve cyclical operation;

[0054] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
