[0051] The working principle of this utility model:

[0052] In this embodiment, the carrier 2 is used to clamp or position the material strip 30. The material strip 30 has an opening and a material strip positioning hole 40. The carrier 2 has a follower protrusion 22. The opening cooperates with the follower protrusion 22. The X-axis moving mechanism 1 drives the carrier 2 along the X-axis, thereby driving the material strip 30 along the X-axis direction. Since the X-axis direction is set at the moving end of the Y-axis moving mechanism 4, the Y-axis moving mechanism 4 can move the X-axis moving mechanism 1 and the carrier 2 linearly along the Y-axis direction. The cutting mechanism 7 is arranged on one side of the laser 5 in the Y-axis direction. In this embodiment, the Y-axis direction is the front-to-back direction, and the cutting mechanism 7 is located behind the laser 5. Therefore, the Y-axis moving mechanism 4 is used to switch the material strip 30 on the X-axis moving mechanism 1 and the carrier 2 from the processing position of the cutting mechanism 7 to the position below the laser 5. It can also switch the material strip 30 on the X-axis moving mechanism 1 and the carrier 2 from the position below the laser 5 to the processing position of the cutting mechanism 7, thereby realizing the switching between the two processing stations. Since a cutting area 3 is provided between two adjacent carriers 2, and the width of the cutting area 3 is greater than the width of the knife seat module 72, the cutting area 3 between the two adjacent carriers 2 can be matched to the knife seat module 72 under the drive of the Y-axis moving mechanism 4, so that the carrier 2 and the knife seat module 72 are in the same straight line (X-axis direction), and the X-axis moving mechanism 1 can drive the carrier 2 on the mobile end to the top of the knife seat module 72, and the cutter module 71 can cut the material strip 30. Figure 1 As shown, the left and right horizontal directions are along the X-axis direction, and the front and back horizontal directions are along the Y-axis direction.

[0053] In this embodiment, the cutter positioning element 121 is a cutter positioning post, and the cutter holder module 72 is provided with a cutter positioning hole that matches the cutter positioning post, improving the linear fit accuracy between the cutter module 71 and the cutter holder module 72. The product positioning element 73 is provided with a product positioning post that matches the strip positioning hole 40, completing the precise positioning of the strip 30 on the cutter, thereby improving cutting accuracy.

[0054] The bottom of the pressing block 742 is provided with a positioning portion 9 to further compress the material strip 30 to complete the laser welding operation. The first penetration area is located directly above the second penetration area, so the laser beam emitted by the laser 5 can penetrate the first penetration area and the second penetration area from top to bottom. The compression elastic member 743 is used to buffer the rigid contact of the pressing block 742 on the material strip 30, protecting the material strip 30 while positioning and compressing the material strip 30 to facilitate processing by the laser 5. The laser 5 and the lifting mechanism 6 are both provided on the connecting frame. Since the lifting mechanism 6 can drive the cutter module 71 up and down, the lifting mechanism 6 can also drive the pressing frame 741 and the pressing block 742 to descend and compress the material strip 30, cooperating with the laser 5 to achieve segmented lifting control to meet different working conditions.

[0055] The first locating pin 10 is used to further accurately position the material strip 30. The material strip positioning hole 40 can match the first locating pin 10 or the cutter positioning post, both of which are used to fix and position the material strip 30. The first locating pin 10 and the product positioning element 73 can both be pins to position the material strip 30.

[0056] The present invention is provided with a conveying component, which can convey the carrier 2 of the conveyor belt 30 along the X-axis direction. During the conveying process, it can be moved to the cutting component for precise cutting through the matching component or moved to the welding component for laser welding, thereby achieving precise cutting and precise welding. In addition, the cutting component also has a clamping element 74, which can further improve the stability of welding the material belt 30.

[0057] The mounting portion 12 in the cutter module 71 can be connected to the lifting end of the lifting mechanism 6 through other elastic elements to cushion the cutting impact of the cutter head 11 on the material strip 30. The cutter head 11 can be detachably mounted on the mounting portion 12 for easy installation and disassembly. The X-axis moving mechanism 1, the Y-axis moving mechanism 4 and other moving mechanisms can all use screw modules with high linear movement accuracy. The lifting mechanism 6 can use lifting structures such as cylinders and electric cylinders to provide power for cutting the material strip 30. The power supply component 15 can use a UPS power supply to provide power for this cutting and welding machine. The laser 5 can be selected from existing laser equipment with adjustable angles or positions, or a fixed, immovable laser equipment, the output of which can pass through the first penetration area and the second penetration area. As Figure 6As shown, the dotted line portion on the clamping frame 741 is the first through-area, and the dotted line portion on the pressure block 742 is the second through-area. The pad 8 is used to support the material strip 30 for laser processing such as laser welding. The bottom of the cutter head 11 has a certain shape. In this embodiment, it is set as a cutting table 17, specifically having multiple protrusions. The tool holder module 72 has a structure that supports the material strip 30 and has a material port for conveying debris. The display 16 is set on the frame 20 to meet the requirements of automated control and display. Specifically, a touch display screen can be selected. The cutter positioning element 121 can be matched with the top of the tool holder module 72. The top of the tool holder module 72 can be provided with a cutter positioning groove. The cutter positioning groove corresponds to the cutter positioning element 121 to improve the cutting accuracy of the cutter module 71.

[0058] Connecting holes 21 are provided between adjacent carriers 2, allowing them to be connected via connectors. Although not numbered in the figures, these connectors can be connected using metal connectors or other connecting elements to ensure that the movement of the two carriers 2 does not interfere with the spacers 8. Therefore, the connectors should be located above the spacers 8, with their ends connected to the tops of the two adjacent carriers 2.

[0059] The cover 13 can be movably connected to the carrier 2 by means of a hinge or other method to prevent the material strip 30 from arching or folding during transportation, which could damage the material strip 30. The clamp 14 can be rotatably or movably mounted on the carrier 2 to clamp the material strip 30 and prevent the cover 13 from tipping over.

[0060] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
