[0024] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0025] like Figure 1 and Figure 2 As shown, the strip welding machine of this embodiment includes a housing 10. A set of casters 11 is installed at the bottom of the housing 10, and handles 12 are provided at the front and rear ends of the housing 10 for easy movement. A dustproof section is fixed to the upper end of the housing 10, consisting of an upper cover 13 and an internal H-shaped bracket 14. The H-shaped bracket 14 has a vertical groove 140. The laser generator 20 is fixed to the H-shaped bracket 14 via a mounting plate, and its height is adjusted in the vertical groove 140 using screws, thereby adjusting the laser emission position. A light-emitting section is located at the front end of the dustproof section, from which the light from the laser generator 20 is emitted.

[0026] A welding area is provided on the casing 10 below the photolithography section. The welding area has a positioning mounting position with multiple threaded connection holes 15 arranged on the positioning mounting position for mounting the strip welding positioning fixture 30. The welding area also has a material tray 17 connected by a 90-degree bracket 16, which is used to hold the strip to be welded.

[0027] like Figure 3 , Figure 4 and Figure 5As shown, the strip welding positioning fixture 30 includes a base plate 31, which is fixed to the threaded connection hole 15 of the positioning mounting position by bolts. A fixed clamping plate 32 is provided on the base plate 31, and a clamping plate 33 is pivotally connected to one end of the fixed clamping plate 32. The clamping plate 33 can rotate around a pivot, clamping or separating from the fixed clamping plate 32. A welding port 330 is provided on the clamping plate 33. When the clamping plate 33 is closed, the welding port 330 corresponds to the light emission end of the laser generator 20, allowing the laser to pass through and perform welding.

[0028] A floating strip insertion and positioning structure is arranged on the fixed clamping plate 32. The strip insertion and positioning structure includes a positioning pin 34 and an elastic element 35. The positioning pin 34 consists of a large-diameter end, a small-diameter end, and a pointed tip. The large-diameter end slides into the movable insertion hole 320 of the fixed clamping plate 32, while the small-diameter end and the pointed tip pass through the fixed clamping plate 32 and are inserted into the insertion hole 331 of the clamping plate 33. The elastic element 35 is located at the bottom of the positioning pin 34, pushing the positioning pin 34 upward to float, allowing the small-diameter end to insert into the strip, thus achieving positioning. A fixed plate is provided at the bottom of the fixed clamping plate 32, and the bottom of the elastic element 35 contacts the fixed plate, providing elasticity. In this embodiment, the elastic element 35 is a spring.

[0029] The fixed clamping plate 32 has a guide groove 321 along its length. The guide groove 321 is designed to accommodate the material strip, and when the material strip is disengaged from the positioning pin 34, it can be pulled along the guide groove 321. The guide groove 321 has a step 322. When the clamping plate 33 is closed, the pressing edge 332 on the clamping plate 33 cooperates with the step 322 to press the material strip and prevent it from moving.

[0030] The limiting structure includes guide posts 323 symmetrically arranged on both sides of the fixed clamping plate 32, and positioning slots 333 on the clamping plate 33 corresponding to the guide posts 323. When the clamping plate 33 is closed, the guide posts 323 are inserted into the positioning slots 333 to ensure that the clamping plate 33 is aligned with the fixed clamping plate 32, thereby improving positioning accuracy. In addition, in this embodiment, to prevent the clamping plate 33 and the fixed clamping plate 32 from loosening when clamped, attractive magnetic blocks are embedded on the clamping plate 33 and the fixed clamping plate 32. The magnetic blocks attract each other, thereby preventing the clamping plate 33 from loosening and avoiding excessive pressure, thus preventing the clamping plate 33 from deforming when pressing the material strip.

[0031] In addition, the base plate 31 is provided with adjustable side positioning blocks 36. The side positioning blocks 36 contact one side of the fixed clamping plate 32. The side positioning blocks 36 have adjustment grooves 360 on opposite sides. The base plate 31 is provided with connecting holes. Bolts are passed through the adjustment grooves 360 and connected to the connecting holes. The position of the side positioning blocks 36 can be adjusted in one direction. The side positioning blocks 36 can ensure that the fixed clamping plate 32 is in a horizontal state, prevent the fixed clamping plate 32 from tilting, and improve the flatness of the welding end face of the strip.

[0032] In one embodiment, an electronic control unit is housed inside the chassis 10 and is electrically connected to the laser generator 20. A touch screen 18 is located near the laser emission unit and is connected to the electronic control unit, allowing the user to set welding parameters and control the welding process via the touch screen 18.

[0033] During operation, the strip is placed on the fixed clamping plate 32 and initially positioned using the strip insertion and positioning structure. Then, the clamping plate 33 is closed, and the limiting structure ensures alignment. The pressing edge 332 presses the strip tightly. The laser generating device 20 emits a laser, which welds the strip through the welding port 330. Due to precise positioning, the welding quality is high.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
