[0051] Working principle of the present invention:

[0052] In this embodiment, the carrier 2 is used to clamp or position the material belt 30. The material belt 30 has an opening and a material belt 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 to move along the X-axis, so it can drive the material belt 30 to move 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 set on one side of the Y-axis direction of the laser 5. In this embodiment, the Y-axis direction is the front-to-back direction, and the cutting mechanism 7 is located at the rear side of the laser 5. Therefore, the Y-axis moving mechanism 4 is used to switch the material belt 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 belt 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 to realize the switching of 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 driving 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 moving 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 direction is along the X-axis direction, and the front and back horizontal direction is along the Y-axis direction.

[0053] In this embodiment, the cutter positioning element 121 is a cutter positioning column, and the cutter seat module 72 is provided with a cutter positioning hole that matches the cutter positioning column, thereby improving the linear matching accuracy between the cutter module 71 and the cutter seat module 72. The product positioning element 73 is provided with a product positioning column, which can match the material belt positioning hole 40 to complete the precise positioning of the material belt 30 on the cutter, thereby improving the 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 action. 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 in sequence. The compression elastic member 743 is used to buffer the rigid contact of the pressing block 742 with the material strip 30, and can position and compress the material strip 30 while protecting the material strip 30, so as to facilitate the processing of the laser 5. The laser 5 and the lifting mechanism 6 are both arranged on the connecting frame. Since the lifting mechanism 6 can drive the cutter module 71 to rise and fall, the lifting mechanism 6 can simultaneously drive the pressing frame 741 and the pressing block 742 to descend to compress the material strip 30, cooperate with the laser 5 to realize segmented lifting control, and meet different working conditions.

[0055] The first positioning pin 10 is used for further accurate positioning of the material strip 30. The material strip positioning hole 40 can match the first positioning pin 10 or the cutter positioning column, both of which are used to fix and position the material strip 30. The first positioning pin 10 and the product positioning element 73 can both be pins for positioning 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 to achieve 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 buffer 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 select screw modules with high linear movement accuracy. The lifting mechanism 6 can select lifting structures such as cylinders and electric cylinders to provide power for cutting the material strip 30. The power supply component 15 can select a UPS power supply to provide power for the cutting and welding machine. The laser 5 can be selected as an existing laser device with adjustable angle or position, or a fixed and immovable laser device, and the laser beam output by it can pass through the first penetration area and the second penetration area. Figure 6 As shown, the dotted line portion on the clamping frame 741 is the first penetration area, the dotted line portion of the clamping block 742 is the second penetration area, the cushion block 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, and this embodiment is set as a cutting table 17, specifically having a plurality of protrusions, and the cutter seat module 72 has a structure to support the material strip 30, and also has a material port to convey 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 match the top of the cutter seat module 72, and the top of the cutter seat module 72 can be provided with a cutter positioning groove, and the cutter positioning groove corresponds to the cutter positioning element 121, so as to improve the cutting accuracy of the cutter module 71.

[0058] A connecting hole 21 is provided between two adjacent carriers 2, and the connecting holes 21 can be connected by a connecting piece. Although not indicated by a number in the figure, the two carriers 2 can be connected by connecting elements such as a metal connecting piece, and it is ensured that the movement of the two carriers 2 does not interfere with the cushion block 8. Therefore, the connecting piece should be located above the cushion block 8, and the two ends are connected to the top of the two adjacent carriers 2 respectively.

[0059] The cover plate 13 can be movably connected to the carrier 2 by means of hinges, etc., to prevent the material belt 30 from arching or folding during the conveying process, which may damage the quality of the material belt 30. The clamp 14 can be rotatably or movably installed on the carrier 2, and can be used to press the material belt 30 to prevent the cover plate 13 from turning over.

[0060] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above-mentioned technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
