Description

Technical Field

[0001] This utility model belongs to the field of lithium battery nickel strip cutting technology, specifically relating to a high-precision cutting and forming equipment for lithium battery nickel strips. Background Technology

[0002] Nickel stripe is a core connecting material for lithium battery pack packaging. Due to its excellent conductivity, corrosion resistance and welding compatibility, nickel stripe is widely used in the tab connection and module busbar of cylindrical, square and pouch lithium batteries. It is mainly used for the tab connection inside the lithium battery pack and the production of series and parallel busbars for battery modules. It is commonly found in the fields of power batteries for new energy vehicles, energy storage batteries and consumer electronics batteries. Moreover, the thickness and width specifications can be customized according to the power requirements of the battery. Therefore, it is a key basic material to ensure the safety and performance of lithium battery packs. Nickel stripe needs to be cut and processed by cutting and forming equipment.

[0003] Currently, existing lithium battery nickel strip cutting and forming equipment typically requires the end of the nickel strip roll to pass through the bottom of the cutting mechanism, and then a hydraulic cylinder is used to drive the cutting blade downwards to cut the lithium battery nickel strip. However, traditional lithium battery nickel strip cutting and forming equipment does not have a good limiting structure for both sides of the lithium battery nickel strip, which may cause it to be skewed during the cutting process, affecting the flatness of the cut and thus reducing the cutting accuracy of the lithium battery nickel strip. Utility Model Content

[0004] The purpose of this invention is to provide a high-precision cutting and forming equipment for lithium battery nickel strips. This addresses the problem that existing lithium battery nickel strip cutting and forming equipment typically requires the end of the nickel strip roll to pass through the bottom of the cutting mechanism, and then a hydraulic cylinder is used to drive the cutting blade downwards to cut the lithium battery nickel strip. However, traditional lithium battery nickel strip cutting and forming equipment lacks a good limiting structure on both sides of the lithium battery nickel strip, which may cause it to skew during the cutting process, affecting the flatness of the cut and thus reducing the cutting precision.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-precision cutting and forming equipment for lithium battery nickel strips, comprising a cutting machine body, a fixed frame fixedly connected to the top of the cutting machine body, a hydraulic cylinder mounted on the top of the fixed frame, a cutter seat connected to the output end of the hydraulic cylinder, and a cutting blade mounted on the bottom of the cutter seat; A cutting table is installed on the inner side of the cutting machine body. A placement frame is installed at one end of the cutting machine body. A mounting frame is fixedly connected to the top of the cutting machine body. A connecting seat is installed on the top of the mounting frame. A motor is installed at one end of the connecting seat. A bidirectional lead screw is connected to the output end of the motor. Two threaded sleeves are threadedly connected to the outer wall of the bidirectional lead screw. A connecting block is fixedly connected to the bottom of the two threaded sleeves. A limit plate is installed at one end of the connecting block.

[0006] As a preferred embodiment of the high-precision cutting and forming equipment for lithium battery nickel strips of this utility model, two limiting plates are provided, and the two limiting plates are symmetrically distributed on the top of the cutting machine body.

[0007] As a preferred embodiment of the high-precision cutting and forming equipment for lithium battery nickel strips of this utility model, the end of the bidirectional lead screw away from the motor is connected to the connecting seat through a bearing to form a rotating connection structure.

[0008] As a preferred embodiment of the high-precision cutting and forming equipment for lithium battery nickel strips of this utility model, a guide rod is fixedly connected inside the connecting seat, and one end of the connecting block is sleeved on the outer wall of the guide rod.

[0009] As a preferred embodiment of the high-precision cutting and forming equipment for lithium battery nickel strips of this utility model, a collection box is provided on the inner side of the cutting machine body, and the collection box is located directly below the cutting table.

[0010] As a preferred embodiment of the high-precision cutting and forming equipment for lithium battery nickel strips of this utility model, the outer wall of the collection box is fixedly connected with a slider, and the inner wall of the cutting machine body is provided with a sliding groove. The collection box can form a sliding connection structure with the cutting machine body through the slider and the sliding groove.

[0011] As a preferred embodiment of the high-precision cutting and forming equipment for lithium battery nickel strips of this utility model, a control panel is installed on the outer wall of the fixed frame, a connecting frame is installed on the top of one end of the cutting machine body, and a guide roller is rotatably connected to the inner side of the connecting frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By passing the end of the lithium battery nickel strip roll between the cutting machine body and the guide roller, and then exiting from the bottom of the cutting blade, the motor drives the bidirectional lead screw to rotate. This causes the two threaded sleeves connected to the outer wall to move the connecting blocks along the guide rod in opposite directions or in opposite directions. At the same time, the two connecting blocks will drive the limiting plates to move in opposite directions or in opposite directions. By adjusting the distance between the two limiting plates, the two sides of the lithium battery nickel strip can be limited, thereby effectively preventing the lithium battery nickel strip from skewing during cutting and improving the cutting accuracy.

[0013] By setting up a collection box, slider, and chute, and utilizing the sliding connection structure between the collection box and the cutting machine body, the collection box is introduced into the cutting machine body from one end, allowing the slider to slide along the chute. This allows the collection box to be placed on top of the cutting table, so that when the cutting table cuts lithium battery nickel strips, it can collect the falling metal shavings, thus facilitating subsequent cleaning.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4 The present invention provides the following technical solution: a high-precision cutting and forming equipment for lithium battery nickel strip, including a cutting machine body 1, a fixed frame 2 fixedly connected to the top of the cutting machine body 1, a hydraulic cylinder 3 installed on the top of the fixed frame 2, a cutter seat 4 connected to the output end of the hydraulic cylinder 3, and a cutting blade 5 installed at the bottom of the cutter seat 4. A cutting table 6 is installed on the inner side of the cutting machine body 1. A placement frame 7 is installed at one end of the cutting machine body 1. A mounting frame 8 is fixedly connected to the top of the cutting machine body 1. A connecting seat 9 is installed on the top of the mounting frame 8. A motor 10 is installed at one end of the connecting seat 9. A bidirectional lead screw 11 is connected to the output end of the motor 10. Two threaded sleeves 12 are threadedly connected to the outer wall of the bidirectional lead screw 11. A connecting block 13 is fixedly connected to the bottom of the two threaded sleeves 12. A limit plate 14 is installed at one end of the connecting block 13. It should be noted that there are two placement racks 7, which are used to hold lithium battery nickel strip rolls.

[0018] Preferably, there are two limiting plates 14, and the two limiting plates 14 are symmetrically distributed on the top of the cutting machine body 1. The end of the bidirectional lead screw 11 away from the motor 10 forms a rotating connection structure with the connecting seat 9 through a bearing. The connecting seat 9 is fixedly connected to a guide rod 15, and one end of the connecting block 13 is sleeved on the outer wall of the guide rod 15.

[0019] In practical use, the end of the lithium battery nickel strip roll is passed between the cutting machine body 1 and the guide roller 21, and then passes out from the bottom of the cutting blade 5. At this time, the motor 10 drives the bidirectional lead screw 11 to rotate, so that the two threaded sleeves 12 connected to the outer wall can drive the connecting block 13 to move towards or opposite to each other along the guide rod 15. At the same time, the two connecting blocks 13 will drive the limiting plate 14 to move towards or opposite to each other. By adjusting the distance between the two limiting plates 14, the two sides of the lithium battery nickel strip can be limited, thereby effectively preventing the lithium battery nickel strip from being skewed during cutting and thus improving the cutting accuracy.

[0020] Preferably, a collection box 16 is provided on the inner side of the cutting machine body 1, and the collection box 16 is located directly below the cutting table 6. A slider 17 is fixedly connected to the outer wall of the collection box 16, and a groove 18 is provided on the inner wall of the cutting machine body 1. The collection box 16 can form a sliding connection structure with the cutting machine body 1 through the slider 17 and the groove 18.

[0021] In practical use, through the arrangement of the collection box 16, slider 17, and slide groove 18, and utilizing the sliding connection structure between the collection box 16 and the cutting machine body 1, the collection box 16 is introduced into the cutting machine body 1 from one end, allowing the slider 17 to slide along the slide groove 18. This allows the collection box 16 to be placed on top of the cutting table 6. When the cutting table 6 cuts lithium battery nickel strips, it can collect the falling metal shavings, thus facilitating subsequent cleaning.

[0022] Preferably, a control panel 19 is installed on the outer wall of the fixed frame 2, and a connecting frame 20 is installed on the top of one end of the cutting machine body 1. A guide roller 21 is rotatably connected to the inner side of the connecting frame 20.

[0023] In actual use, the cutting machine body 1, hydraulic cylinder 3 and motor 10 can be operated through the control panel 19. The end of the lithium battery nickel strip roll can be passed between the cutting machine body 1 and the guide roller 21 to play a guiding role. It should be noted that the wiring terminals of the cutting machine body 1, hydraulic cylinder 3 and motor 10 are connected to the control panel 19 and the external power supply.

[0024] Working principle: First, the lithium battery nickel strip roll is placed on the placement rack 7. Then, the end of the lithium battery nickel strip roll passes between the cutting machine body 1 and the guide roller 21, and then exits from the bottom of the cutting blade 5. At this time, the motor 10 is controlled by the control panel 19 to drive the bidirectional lead screw 11 to rotate, so that the two threaded sleeves 12 connected by the outer wall can drive the connecting block 13 to move towards or opposite to each other along the guide rod 15. At the same time, the two connecting blocks 13 will drive the limiting plate 14 to move towards or opposite to each other. By adjusting the distance between the two limiting plates 14, the lithium battery nickel strip can be adjusted on both sides. The limit switch effectively prevents the lithium battery nickel strip from skewing during cutting. At this time, the hydraulic cylinder 3 can be stepped on via the control panel 19 to drive the cutting blade 5 to descend and cut the lithium battery nickel strip. Through the setting of the collection box 16, slider 17, and slide groove 18, the collection box 16 is inserted into the cutting machine body 1 from one end by utilizing the sliding connection structure between the collection box 16 and the cutting machine body 1. The slider 17 can slide along the slide groove 18, thereby setting the collection box 16 on the top of the cutting table 6. When the cutting table 6 cuts the lithium battery nickel strip, it can collect the falling metal chips, which facilitates later cleaning.

[0025] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
