[0042] Reference Figures 1 to 3The embodiment of the utility model provides an integrated production device for processing explosion-proof wires of battery shells, including a reversing roller 100, an etching device 200, a reeling device 300, a guide roller 800, a rolling device 400, a welding device 500 and a slitting device 600 arranged in sequence, the reeling device 300 is used to convey the material to the etching device 200, and the etching device 200 is used to etch an explosion-proof wire 701 on the surface of the material strip 700. The rolling device 400 is provided with a plurality of bending rollers 401, and the plurality of bending rollers 401 are connected to a driving device. The plurality of bending rollers 401 rotate to gradually roll the material strip 700 into a tubular material 710 with a rectangular cross section. The outer wall of the tubular material 710 has a gap 702, and the welding device 500 is used for welding and filling the gap 702. The welding device 500 can connect and weld the tubular material 710, and the welding device 500 does not need to be stopped, thereby improving production efficiency. The slitting device 600 is provided with a cutting table 620, which can cut the tubular material 710 into individual shells. The cutting table 620 can move along the conveying direction of the material strip 700, so that the slitting device 600 does not need to stop when cutting individual shells, thereby improving production efficiency. The material strip 700 between the reversing roller 100 and the guide roller 800 is in a relaxed state. Along the height direction of the etching device 200, the material strip 700 between the reversing roller 100 and the guide roller 800 is located above the etching device 200 and the unwinding device 300.

[0043] It can be understood that in some embodiments of the present invention, when an integrated production device for processing explosion-proof wires of a battery shell is used, the unwinding device 300 transmits the material strip 700 to the etching device 200, and the etching device 200 etches the explosion-proof wire 701 from the material strip 700. After the etching of the explosion-proof wire 701 is completed, the reversing roller 100 changes the conveying direction of the material strip 700 so that the explosion-proof wire 701 is located on the bottom surface of the material strip 700. The reversing roller 100 and the guide roller 800 guide the material strip 700 from above the etching device 200 and the unwinding device 300 to the rolling device 400, that is, the material strip 700 between the reversing roller 100 and the guide roller 800 is located above the etching device 200 and the unwinding device 300. The material strip 700 is gradually rolled into a tubular material 710 with a rectangular cross-section in the rolling device 400, and the tubular material 710 passes through the welding device 500 to weld the gap 702. After the welding gap 702 of the tubular material 710 is completed, it enters the slitting device 600, and the cutting table 620 of the slitting device 600 moves along the conveying direction of the tubular material 710 to cut a single battery shell. Through the integrated production equipment for processing explosion-proof wires of battery shells in the embodiment of the utility model, the integrated production and processing of battery shells with explosion-proof wires is realized, which saves the labor input of equipment conversion and improves production efficiency.

[0044] It can be understood that by etching the explosion-proof line 701 on the material strip 700, the process flow is simplified and the process occupancy is reduced compared to welding explosion-proof holes on the surface of the material strip 700. At the same time, it is avoided to punch explosion-proof holes and weld explosion-proof plates on the surface of the material strip 700 to improve the surface strength of the material strip 700 and improve the yield rate of processing. The material strip 700 between the reversing roller 100 and the guide roller 800 is in a relaxed state, so that the etching device 200 has sufficient processing time, and then the etching device 200 and the rolling device 400 can achieve continuous processing without stopping, thereby improving production efficiency. Since the material strip 700 between the reversing roller 100 and the guide roller 800 is located above the etching device 200 and the unwinding device 300, the space utilization rate is improved and the production occupancy is reduced.

[0045] It can be understood that the reversing roller 100 is connected to a driving device so that after the etching device 200 is processed, the reversing roller 100 can drive the etched material strip 700 to enter between the reversing roller 100 and the guide roller 800, so that the etching device 200 does not need to stop to etch the explosion-proof line 701, thereby improving production efficiency. Several bending rollers 401 of the rolling device 400 are connected to a driving device so that the material strip 700 can continuously enter the rolling device 400 from the guide roller 800 for processing. At the same time, since the welding device 500 can continuously weld the gap 702 of the tubular material 710, and the cutting table 620 can move along the conveying direction of the tubular material 710, continuous welding of the tubular material 710 and slitting of a single battery shell are realized, thereby realizing that an integrated production device for processing explosion-proof lines of a battery shell in an embodiment of the utility model can continuously process and produce battery shells in a one-line process without stopping, thereby improving production efficiency.

[0046] It can be understood that exposing the explosion-proof wire 701 on the outer wall of the battery shell facilitates the inspection and maintenance of the explosion-proof wire 701. At the same time, compared with the explosion-proof wire 701 set on the inner wall of the battery shell, it has a better explosion-proof effect, ensures the explosion-proof requirements of the battery shell, and improves the safety of the battery shell.

[0047] Reference Figure 1 and Figure 2 In some embodiments of the present invention, the etching device 200 is provided with an etcher 210, a material puller 220 and a material feeder 230, and the material puller 220 is located at one end of the etching device 200 close to the unwinding device 300. The etcher 210 is located between the material puller 220 and the material feeder 230, and the material strip 700 between the material feeder 230 and the material puller 220 is in a straightened state to ensure that the material strip 700 is stable when processing the explosion-proof wire 701, thereby ensuring the processing quality of the explosion-proof wire 701.

[0048] Reference Fig.10It can be understood that the puller 220 is rotatably connected to two leveling rollers 221, the two leveling rollers 221 are arranged along the height direction of the puller 220, a gap 702 is formed between the two leveling rollers 221 for the material belt 700 to pass through, and the leveling rollers 221 are connected to a driving device. The leveling rollers 221 are connected to a driving device so that the puller 220 can convey the material belt 700. It can be understood that the material belt 700 between the unwinding device 300 and the etching device 200 can be in a relaxed state, and the puller 220 is connected to a driving device, so that the material belt 700 between the unwinding device 300 and the etching device 200 can be conveyed to the etcher 210, so that the unwinding device 300 can continuously convey the material belt 700.

[0049] It is understandable that the material belt 700 of the unwinding device 300 and the etching device 200 may not be in a relaxed state, and the conveying speed of the material belt 700 of the etching device 200 is consistent with the conveying speed of the material belt 700 of the unwinding device 300, and continuous processing of the etching device 200 can also be achieved. This application is not limited here.

[0050] Reference Figure 2 In some embodiments of the utility model, the etcher 210 is a laser engraving machine. By controlling the movement of the light source inside the laser engraving machine, the shape of the explosion-proof line 701 is etched on the surface of the material strip 700. The etcher 210 is connected to a lifting assembly 240, and the lifting assembly 240 includes a lifting block 241 and a lifting rod 242. The lifting rod 242 is arranged along the height direction of the etcher 210. The lifting block 241 is slidably connected to the lifting rod 242. The lifting block 241 can move along the height direction of the lifting rod 242. The etcher 210 is connected to the lifting block 241, and the lifting block 241 drives the etcher 210 to move along the height direction of the etcher 210 to adjust the welding focal length of the etcher 210 to ensure the processing quality of the explosion-proof line 701, thereby adapting to the welding of explosion-proof lines 701 of different shapes and sizes, and improving the applicability of the etching device 200.

[0051] Reference Figure 2 It can be understood that, in the horizontal plane, the shape of the explosion-proof wire 701 is C-shaped. The shape of the explosion-proof wire 701 can also be other shapes. The specific shape and size of the explosion-proof wire 701 can be selected according to actual production, and this application does not limit it here.

[0052] Reference Figure 3In some embodiments of the present invention, along the height direction, the two side walls of the tubular material 710 are the first side wall 711 and the second side wall 712, and the explosion-proof line 701 is located on the outer wall surface of the first side wall 711, that is, the explosion-proof line 701 is located on the outer wall surface of the battery housing. The gap 702 is located on the second side wall 712, and the two side walls of the tubular material 710 along its width direction are the third side wall 713 and the fourth side wall 714. Since the gap 702 is located on the second side wall 712, compared with the gap 702 being located at the connection between the two side walls, it is convenient for the welding device 500 to weld the gap 702, reducing the welding difficulty and reducing the processing difficulty.

[0053] Reference Figure 3 and Figure 4 In some embodiments of the utility model, the rolling device 400 includes a pre-adjusting component 410, a shaping component 420 and a forming component. The pre-adjusting component 410 is used to roll and fold the two sides of the material strip 700 into side edges 715, and the two side edges 715 are used to form a second side wall 712. The shaping component 420 is used to gradually roll and fold the material strip 700 into a third side wall 713 and a fourth side wall 714. The forming component is used to roll and fold the material strip 700 into a tubular material 710, thereby gradually rolling and folding the material strip 700 into a tubular material 710 with a rectangular cross-section.

[0054] It is understandable that the angle between the side edge 715 rolled by the pre-adjusting component 410 and the material strip 700 is greater than 90°, so as to avoid the side edge 715 affecting the processing of the third side wall 713 and the fourth side wall 714 during subsequent processing.

[0055] Reference Figure 3 It can be understood that the shaping component 420 includes a first component 421 and a second component 422. The first component 421 is used to adjust the angles of the third side wall 713 and the fourth side wall 714 with the first side wall 711, and the second component 422 is used to adjust the angles of the two side edges 715 with the third side wall 713 and the fourth side wall 714. At the same time, the second component 422 can also further adjust the angles of the third side wall 713 and the fourth side wall 714 with the first side wall 711, so as to gradually adjust the shape of the material strip 700 by rolling.

[0056] Reference Figure 4It can be understood that the first component 421 can be two bending rollers 401 arranged along the height direction of the material strip 700, the two bending rollers 401 respectively have an oblique cross-section, and the angles of the third side wall 713 and the fourth side wall 714 are folded out by the shape of the two bending rollers 401; the first component 421 can also be two bending rollers 401 arranged along the height direction of the material strip 700, which press the two surfaces of the second side wall 712 respectively, and two first adjusting rollers 423 are arranged along the width direction of the material strip 700. The first adjusting roller 423 rotates around the height direction of the material strip 700, and the first adjusting roller 423 is in the shape of a truncated cone, that is, the first adjusting roller 423 has a trapezoidal cross-section, and the angles of the third side wall 713 and the fourth side wall 714 are folded out by the first adjusting roller 423.

[0057] Reference Figure 4 It can be understood that the second component 422 is provided with a second adjusting roller 424 and two first adjusting rollers 423. The second adjusting roller 424 and a bending roller 401 are arranged at intervals along the height direction of the material strip 700. The bending roller 401 rolls the first side wall 711, and the second adjusting roller 424 rolls the two side edges 715 at the same time to adjust the angles of the two side edges 715 with the third side wall 713 and the fourth side wall 714 respectively. The two first adjusting rollers 423 are arranged at intervals along the width direction of the material strip 700. The first adjusting roller 423 is used to roll the third side wall 713 and the fourth side wall 714, and further adjust the angles of the third side wall 713 and the fourth side wall 714 with respect to the first side wall 711, so as to further adjust the shape of the material strip 700 through the second component 422.

[0058] It can be understood that the number of first components 421 can be multiple, the cross-sectional shapes of the bending rollers 401 between the multiple first components 421 are different, and the cross-sectional shapes of the first adjusting rollers 423 are different, so as to gradually adjust the angles of the third side wall 713 and the fourth side wall 714 relative to the first side wall 711, respectively, so as to improve the material properties of the tubular material 710. The number of first components 421 should be selected according to actual production, and this application does not limit it here.

[0059] It is understandable that the number of second components 422 can be multiple, and the cross-sectional shape of the first adjustment roller 423 and the cross-sectional shape of the second adjustment roller 424 between the multiple second components 422 are different, so as to gradually adjust the angles of the side edge 715, the third side wall 713, and the fourth side wall 714 to improve the material properties of the tubular material 710. The number of second components 422 can be selected according to actual production, and the present application does not limit it here.

[0060] Reference Figure 5 and Figure 8Optionally, the cutting table 620 is provided with a frame 621, a plurality of sliders 622 are provided at the bottom of the frame 621, the slitting device 600 is provided with a guide rail 610, the guide rail 610 is arranged along the conveying direction of the material belt 700, and the slider 622 can move along the guide rail 610 to drive the cutting table 620 to be arranged along the conveying direction of the material belt 700, so that when the cutting table 620 cuts a single shell, it can move with the conveying of the material belt 700.

[0061] Reference Figure 5 Optionally, a sawing knife 630 is provided on the frame 621, and the sawing knife 630 is connected to a driving device, and the driving device drives the sawing knife 630 to rotate to cut the tubular material 710, thereby realizing the cutting of the tubular material 710 with a shell.

[0062] Reference Figures 6 to 8 Optionally, a conveyor platform 640 is slidably mounted on the frame 621, and a pressure rod 641 is fixedly mounted on the conveyor platform 640. The conveyor platform 640 can move along the width direction of the frame 621, so that the pressure rod 641 drives the tubular material 710 to move toward the sawing knife 630, so that the sawing knife 630 cuts the tubular material 710 into a single shell.

[0063] It can be understood that when the pressure rod 641 drives the tubular material 710 to move, the tubular material 710 is deformed along its conveying direction. The tubular material 710 between the welding device 500 and the slitting device 600 has a preset length so that the deformation of the tubular material 710 along its conveying direction will not affect the processing of the welding device 500, thereby enabling the connection processing between the welding device 500 and the slitting device 600.

[0064] Reference Figure 6 and Fig. 9 Optionally, the frame 621 is provided with a guide rod 623 along its width direction, and the side wall of the guide rod 623 is provided with two limit plates 624, and the two limit plates 624 are located at both ends of the guide rod 623. The conveying platform 640 is rotatably connected with a first pulley 643 and a second pulley 644.
