[0033] In this embodiment, the cutting mechanism is used to cut the pole ear 103 of the battery cell 102. The pole ear 103 of the battery cell 102 is placed between the upper cutter 11 and the lower cutter 12. The upper cutter 11 is driven by the cylinder to move along the guide rail 13 toward the lower cutter 12 to cut the pole ear 103 of the battery cell 102 placed between the upper cutter 11 and the lower cutter 12. The guide rail 13 is used to ensure that the upper cutter 11 moves up and down, and the first vertical plate 14 is used to install the guide rail 13 distributed in the upper and lower directions. The shaping mechanism is used to flatten and shape the pole ear 103 of the battery cell 102. The pole ear 103 of the battery cell 102 is placed between the upper shaping block 21 and the lower shaping block 22. The upper shaping block 21 is driven by the cylinder to move along the guide column 23 to the lower shaping block 22 to flatten the pole ear 103 of the battery cell 102 placed between the upper shaping block 21 and the lower shaping block 22. The second vertical plate 24 is used to install the guide column 23 distributed in the upper and lower directions.

[0034] The base 3 is used to support and fix the cutting mechanism and the shaping mechanism to realize the movement of the cutting and shaping device. In one embodiment, the base 3 is also equipped with a plurality of adjustable support feet, and the height of the adjustable support feet can be changed to realize that the base 3 can be stably placed on an uneven plane.

[0035] Compared with the prior art, the technical effects achieved by the embodiments of the present invention include:

[0036] The positions of the upper cutter 11 and the lower cutter 12 are fixed by the base 3 and the first vertical plate 14, and the moving direction of the upper cutter 11 is limited by the guide rail 13. The operator only needs to drive the upper cutter 11 to move to smoothly cut the pole ear 103 of the battery cell 102, thereby avoiding the phenomenon of uneven end face, inconsistent length, short circuit caused by cutting and the like caused by manual cutting, thereby improving production efficiency. After completing the cutting step, the pole ear 103 of the battery cell 102 can be shaped by the shaping mechanism. The positions of the upper shaping block 21 and the lower shaping block 22 are fixed by the base 3 and the second vertical plate 24, and the moving direction of the upper shaping block 21 is limited by the guide column 23. The operator only needs to drive the upper shaping block 21 to move to flatten the pole ear 103 of the battery cell 102. The operator is fast and efficient from the cutting step to the shaping step, and the movements are similar, which can greatly simplify the assembly steps.

[0037] Continue to see Figure 1-9 In this embodiment, a movable plate 4 is further included. The movable plate 4 is connected to the upper cutter 11 and the guide rail 13 respectively. The upper cutter 11 is arranged on the movable plate 4.

[0038] Specifically, the upper cutter 11 is mounted on the movable plate 4, and the movable plate 4 is engaged with the guide rail 13, so that the movable plate 4 can drive the upper cutter 11 to move up and down along the guide rail 13. The upper cutter 11 is fixed by the movable plate 4, which reduces the customization requirements of the upper cutter 11 and is conducive to the maintenance and replacement of the upper cutter 11.

[0039] Furthermore, it also includes a pressing mechanism 5 , which is arranged on the movable plate 4 and on one side of the upper cutter 11 .

[0040] Specifically, the upper cutter 11 moves up and down along the guide rail 13 to cut the length of the tab 103 of the battery cell 102. During the cutting process, the pressing mechanism 5 first presses the battery cell 102 as a whole to prevent the battery cell 102 from loosening. Then, the upper cutter 11 and the lower cutter 12 engage to ensure that the tab 103 of the battery cell 102 is smooth and has the same length. By pressing the battery cell 102 first with the pressing mechanism 5, the cutting accuracy can be effectively improved.

[0041] Furthermore, the pressing mechanism 5 includes a fixed block 51, a buffer member 52, an elastic pressing block 53 and a connecting column 54; the fixed block 51 is provided with a hole and is arranged on the movable plate 4; the connecting column 54 can pass through the hole and is connected to the elastic pressing block 53; the buffer member 52 is sleeved on the connecting column 54 and between the fixed block 51 and the elastic pressing block 53.

[0042] In this embodiment, the pressing mechanism 5 includes a fixed block 51, a buffer 52, an elastic pressing block 53 and a connecting column 54. The connecting column 54 is a U-shaped column. The open side of the connecting column 54 is connected to the elastic pressing block 53. The connecting column 54 passes through the hole of the fixed block 51. The buffer 52 is usually a spring. There are multiple springs, which are respectively mounted on the column body of the connecting column 54. The elastic pressing block 53 is made of elastic material. When the elastic pressing block 53 contacts the battery cell 102, the soft elastic pressing block 53 can tightly press the battery cell 102 to avoid rigid contact with the battery cell 102 to damage the battery cell 102. The movable plate 4 continues to drive the upper cutter 11 and the fixed block 51 to move downward, and the fixed block 51 is connected to the elastic pressing block 53 through the buffer 52 to avoid the elastic pressing block 53 from crushing the battery cell 102.

[0043] Furthermore, it also includes a first driving device 61 , which is disposed on the first vertical plate 14 and connected to the upper cutter 11 .

[0044] Specifically, the first driving device 61 includes a cylinder, which is used to drive the upper cutter 11 to move up and down along the guide rail 13. In one embodiment, the upper cutter 11 is installed on the movable plate 4, the first driving device 61 is fixedly installed on the first vertical plate 14, and the movable plate 4 is installed on the first driving device 61. When the first driving device 61 is in action, the movable plate 4 and the upper cutter 11 are driven to move up and down along the guide rail 13. The first driving device 61 is used to electronically cut the tabs 103 of the battery cell 102, and the electronic and automated cutting has higher production efficiency.

[0045] Furthermore, it also includes a second driving device 62 , which is disposed on the second vertical plate 24 and connected to the upper shaping block 21 .

[0046] Specifically, the second driving device 62 includes a cylinder, which is used to drive the upper shaping block 21 to move up and down along the guide pillar 23. In one embodiment, it includes a plurality of guide pillars 23, which are distributed around the upper shaping block 21. The second driving device 62 is fixedly mounted on the second vertical plate 24. The guide pillar 23 passes through the upper shaping block 21 and is mounted between the base 3 and the second vertical plate 24. When the second driving device 62 is in action, it drives the shaping block to move up and down along the guide pillar 23. The second driving device 62 is used to electronically shape the tabs 103 of the battery cell 102, and the electronic and automated shaping has higher production efficiency.

[0047] In one embodiment, a processor and a switch are further included. The processor is connected to the switch, the first drive device 61 and the second drive device 62 respectively. The delayed execution is realized by the timing unit of the processor. For example, after the switch is started, the processor starts the first drive device 61 and / or the second drive device 62 after 5 seconds. In some other embodiments, two buttons are included. When the two buttons are pressed, the first drive device 61 and / or the second drive device 62 are started, so that the first drive device 61 drives the movable plate 4 and the upper cutter 11 to move up and down along the guide rail 13, and / or the second drive device 62 drives the shaping block to move up and down along the guide column 23. The two buttons can guide the operator to leave the disassembly and cutting mechanism and / or the shaping mechanism with both hands to ensure the personal safety of the operator.

[0048] Furthermore, it also includes a first connecting block 71 and a second connecting block 72, the first connecting block 71 and the second connecting block 72 are respectively arranged on the base 3, the lower cutter 12 is arranged on the first connecting block 71, and the lower shaping block 22 is arranged on the second connecting block 72.

[0049] Specifically, the first connection block 71 is made of insulating material, the surfaces of the upper cutter 11 and the lower cutter 12 are treated with insulation, and the lower cutter 12 is installed on the base 3 through the first connection block 71, which further prevents the base 3 from transmitting static electricity, and effectively prevents the positive and negative tabs 103 of the battery cell 102 from short-circuiting during the cutting process. The second connection block 72 is made of insulating material, the surfaces of the upper shaping block 21 and the lower shaping block 22 are treated with insulation, and the lower shaping block 22 is installed on the base 3 through the second connection block 72, which further prevents the base 3 from transmitting static electricity, and effectively prevents the positive and negative tabs 103 of the battery cell 102 from short-circuiting during the shaping process.

[0050] Furthermore, it also includes an adjusting block 8 , which is disposed on the base 3 and connected to the first connecting block 71 .

[0051] Specifically, the height of the adjustment block 8 is the same as that of the first connection block 71, and is tightly fitted on one side of the first connection block 71, and is used to adjust the position of the lower cutter 12. For example, under normal circumstances, the fitting surfaces of the upper cutter 11 and the lower cutter 12 are seamlessly fitted, but when one of the cutters is deformed due to processing or material characteristics, it cannot be completely fitted with the other cutter surface, thereby affecting the cutting effect (uninterrupted cutting). The lower cutter 12 can be tightened in the direction of deformation by using screws through the adjustment block 8, so that the lower cutter 12 is completely fitted with the upper cutter 11.

[0052] Furthermore, it also includes a first material loading plate 91 , and the lower cutter 12 , the first connecting block 71 and the adjusting block 8 are respectively connected to the first material loading plate 91 and are on the same side of the first material loading plate 91 .

[0053] In this embodiment, the first carrier plate 91 is installed above the lower cutter 12 , the first connecting block 71 and the adjusting block 8 . The first carrier plate 91 has a flat surface for stably placing the battery cells 102 to be cut.

[0054] Furthermore, it also includes a second loading plate 92 , which is disposed on the base 3 and connected to the lower shaping block 22 .

[0055] In this embodiment, the second carrier plate 92 is installed above the lower shaping block 22 and the second connecting block 72 . The second carrier plate 92 has a flat surface for stably placing the battery cells 102 to be shaped.

[0056] In another embodiment, a clamp 101 is further included, and a limit block is installed on the first loading plate 91. The clamp 101 is used to clamp the battery cell 102. The clamp 101 with the battery cell 102 is placed in the limit block to effectively prevent the battery cell 102 from loosening and ensure that the incision is flat and the length is consistent.

[0057] The use process of the cutting and shaping machine is as follows:

[0058] The first step is to put the battery cell 102 into the fixture 101, and the fixture 101 is placed at the limit block of the cutting and feeding plate, and is flat against the lower cutting knife 12; the second step is to set the cutting delay time; the third step is to press the start button with both hands at the same time, and the first drive device 61 drives the upper cutting knife 11 to cut; the fourth step is to complete the cutting, take out the battery cell 102 clamped by the fixture 101 from the cutting mechanism, and place it on the second loading plate 92 of the shaping mechanism, and flatten it against the lower shaping block 22; the fifth step is to set the shaping delay time; the sixth step is to press the panel start button with both hands at the same time, and the second drive device 62 drives the upper shaping block 21 to shape; the seventh step is to complete the shaping, and obtain the cut and shaped battery cell 102.
