The guide motion slider 36 fixed in the cabinet 1 is slidably connected to the guide rail 8-1, so that the grinding mechanism 8 can be extended or retracted along the width direction of the material fixing plate 14 to grind the welding points of the welding material 9.

[0030] Preferably, the welding material 9 supported by the multifunctional metal strip welding machine has a width of 5 to 100 mm, a thickness of 0.1 to 0.8 mm, and is made of copper or stainless steel. The cabinet 1 is provided with universal wheels at the bottom to facilitate the overall movement of the welding machine; a handle 12 is fixed at the lower part of the front end face 1-1 for pushing and pulling the welding machine; a waste box is provided in the cabinet 1, and waste box openings 7 are provided on the left and right sides of the cabinet 1 for operators to put in welding waste; a folder placement box 15 is provided on the right side of the cabinet 1 for placing design drawings and other documents.

[0031] The working process of the present invention is as follows: turn on the power switch 16, start the laser power switch 17, and let a section of welding material 9 enter the left cutting module 21 through the left cutting entrance 6 for flush cutting. The cutting process is as follows: pull the pull rod 26-2 of the material clamping and limiting mechanism 26 to feed the welding material 9 into the cutting opening 26-1 until it passes through the cutting knife mechanism 24, release the pull rod 26-2, and the spring pull rope 28 connected to the pull rod 26-2 passes through the idler wheel 25, and moves along the length direction of the guide rod 27. The material clamping and limiting mechanism 26 and the welding material 9 are kept in a clamped state by the force of the spring pull rope 28; then, find the switch button of the left cutting module 21 through the button panel 11, so that the cutting cylinder 23 drives the cutting knife mechanism 24 to cut off the welding material 9 passing through the material clamping and limiting mechanism 26.

[0032] Place a section of welding material 9 after cutting on the material fixing plate 14 and align it inwardly, extend the positioning tongue 29 of the tongue positioning module 13, align the welding material 9 after it is aligned inwardly with the positioning tongue 29, and then find the button switch of the left material clamping plate 5 through the button panel 11 to clamp and fix the welding material 9, thus completing the material fixation on the left side. Withdraw the positioning tongue 29, and similarly cut and fix the welding material 9 on the right side according to the cutting and fixing steps of the left material.

[0033] The right welding material 9 is passed through the right cutting entrance 18 on the right side of the cabinet 1 and enters the right cutting module 22 for flush cutting, then placed on the material fixing plate 14 and aligned with the inner side, moved to the left until it is completely aligned with the welding material 9 fixed on the left side, and then the button switch of the right material clamping plate 19 is found through the button panel 11 to clamp and fix the welding material 9 on the right side; at this time, all the welding materials 9 are positioned. Then, the program corresponding to the specification of the welding material 9 is selected through the touch screen 2, and the start switch of the laser welder 20 is found on the button panel 11. After pressing the start switch, wait for the laser head protective cover 4 to return to the original position, and then the button switch of the left material clamping plate 5 and the button switch of the right material clamping plate 19 are found on the button panel 11, and the switches are turned on respectively to release the welding material 9 to complete the entire welding process.

[0034] After welding is completed, the welding point is polished and leveled using the polishing mechanism 8. Polishing process: The welding point of the welding material 9 is moved to the front of the polishing mechanism 8, and the operator manually holds the handle 37 of the polishing mechanism 8, and the polishing block 35 fixed on the head of the polishing mechanism 8 moves back and forth along the width direction of the material fixing plate 14, so that the polishing block 35 contacts the surface of the welding material 9, thereby removing the burrs on the raised part of the surface of the welding material 9.

[0035] The present invention has developed a device for welding the head and tail materials in the process of stamping material change preparation through technological innovation and practical application. The welding machine is controlled by a program. After selecting the control program of the corresponding specification, the material is manually placed on the fully open material clamping and positioning platform, and the automatic welding process is realized after the start button is pressed. The entire welding process only takes 1 minute, which saves a lot of time cost compared with the normal material change time of 15 minutes. The left and right edge cutting only produces 15mm of waste and consumes 30mm of material. Compared with the normal waste of more than 10 meters during material change, a lot of material cost is saved.

[0036] It is understandable that, for those skilled in the art, any equivalent replacement or change to the technical solution and inventive concept of the present invention should fall within the protection scope of the claims attached to the present invention.
