A material gripping component A is provided at the bottom of one end of the mounting plate 12, and two sets of sliders 15 are symmetrically arranged at the bottom of the other end of the mounting plate 12. A sliding rod 151 is provided on the slider 15. The sliding rod 151 is inserted into the mounting plate 12 and slidably connected to it. A material gripping component B is provided at the bottom of the slider 15, and a rack A18 is provided at the close end of the two sliders 15 respectively. A gear 19 is rotatably mounted on the mounting plate 12, and the two racks A18 are located on both sides of the gear 19 and mesh with it. The material gripping assembly A includes multiple elastic telescopic tubes A13, suction cups A14, and an air pump 25. Each elastic telescopic tube A13 includes an outer tube, an inner tube, and a spring. The top end of the outer tube is connected to the mounting plate 12. The inner tube is located inside the outer tube and slides along its axial direction. The suction cup A14 is located at the bottom of the inner tube and communicates with it. A positioning block A is installed on the outer tube, and a positioning block B is installed on the inner tube. A spring is fitted onto the outer tube, with its two ends abutting against positioning blocks A and B, respectively. The air pump 25 is mounted on the mounting plate 12, and its input end is connected to an air guide pipe 26. Each outer tube communicates with the air guide pipe 26. The material gripping assembly B includes an elastic telescopic tube B16 and a suction cup B17.

The suction cup B17 is connected to the movable end of the elastic telescopic tube B16 and communicates with the air guide pipe 26.The tensioning assembly includes, but is not limited to, a spring rod 20. The body of the spring rod 20 is connected to one end of the mounting plate 12. The movable end of the spring rod 20 is connected to a crossbar 21. The crossbar 21 is connected to a rack B22. The rack B22 is inserted into the mounting plate 12 and meshes with a gear 19. A baffle 24 is provided on the frame 1. When the crossbar 21 is blocked by the baffle 24, the two sliders 15 slide synchronously in opposite directions. Drive component B is mounted on bracket 5. Drive component B includes a linear module 9 and a hydraulic cylinder 11. A through hole is provided on bracket 5, and a slide block 8 is slidably mounted in the through hole.

The body of the linear module 9 is connected to the upper end face of bracket 5, and the lug is connected to the output end of the linear module 9. A slide frame 10 is provided on the slide block 8 and slides along its height direction. A mounting plate 12 is connected to the bottom of the slide frame 10. The body of the hydraulic cylinder 11 is connected to the slide block 8, and the output end of the hydraulic cylinder 11 is connected to the slide frame 10. Drive component B drives the mounting plate 12 to move in the working state. In the moving state, the mounting plate 12 grabs the raw material to be cut from the placement rack A101 through the material gripping component A and puts it into the bracket 3 of the loading station. At the same time, the material gripping component B puts two cut workpieces from the bracket 3 of the unloading station into the placement rack B102 on the corresponding side.

[0027] It should be noted that the robotic arm 6 is at least a three-axis robotic arm, and the hydraulic cylinder 11 is connected to an external hydraulic pump.

[0028] In this embodiment, the battery sheet to be cut is placed in the placement rack A101. The linear module 9 is activated, which drives the slide block 8 to slide and moves the mounting plate 12, causing the suction cup A14 to move above the placement rack A101. At this time, the suction cup B17 is located directly above the bracket 3 corresponding to the unloading station. The hydraulic cylinder 11 is activated to press down the mounting plate 12 until the suction cup A14 presses against the upper surface of the top layer of the sheet. Then, the air pump 25 is activated, and the air pump 25 draws air, generating suction force in the suction cup A14 and holding the sheet. Then, the mounting plate 12 moves upward, lifting the sheet above the upper end of the placement rack A101. Subsequently, the mounting plate 12 moves laterally. At the same time, due to the lateral movement of the mounting plate 12, the crossbar 21 abuts against the baffle 24, and the rack B22 gradually penetrates into the mounting plate 12. 2 drives gear 19 to rotate, which in turn drives the racks A18 on both sides to slide in opposite directions, causing slider 15 to move suction cups B17 away from each other. When the original sheet is directly above the bracket 3 corresponding to the loading station, the two sets of suction cups B17 are exactly directly above the corresponding side placement rack B102. Then, mounting plate 12 moves down, suction cup A14 puts the original sheet into the bracket 3 below it, then motor 4 drives turntable 2 to rotate 90 degrees, the original sheet rotates to the cutting station, robotic arm 6 drives laser cutting head 7 to move and cut the original sheet. At the same time, suction cup A14 automatically loads the bracket 3 of the current loading station. As turntable 2 rotates, suction cup A14 loads the sheet while suction cup B17 automatically puts the cut battery cells into the corresponding side placement rack B102.

[0029] Example 2

[0030] like Figure 4 and Figure 5 As shown, the photovoltaic profile laser cutting device proposed in this utility model has several rollers 23 arranged on the side of the crossbar 21 facing the baffle 24, compared with Embodiment 1.

[0031] In this embodiment, when the mounting plate 12 moves toward the baffle 24, the roller 23 preferentially contacts the baffle 24. By using the roller 23 to roll in the height direction of the baffle 24, the sliding resistance of the crossbar 21 is reduced, and the harsh noise is avoided.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
