Description

Technical Field

[0001] This utility model relates to the field of lithium battery processing auxiliary equipment technology, and in particular to a lithium battery cutting structure. Background Technology

[0002] Lithium-ion batteries are typically packaged using flexible materials during manufacturing. They are usually connected together and then cut into individual battery cells using a cutter. This cutting process generally requires a cutting structure, typically including a mounting frame, such as a U-shaped frame, within which a vertically moving cutter is installed. The cutter has a blade at its lower end, and the mounting frame has a baffle at one end. During cutting, the connected lithium-ion battery packages are fed to the baffle. When the two battery cells are directly below the blade, the cutter cuts downwards, resulting in individual battery cells. However, in actual manufacturing, because the packaging is flexible, after the battery cell is cut, the connected portion may push forward and press against the cutter. As the cutter quickly returns upwards, the portion pressing against the cutter may cause the cut battery cell to bounce forward. Since lithium-ion batteries are often unstable during manufacturing, this bouncing motion can have serious consequences (such as the battery cell hitting the ground, which could exacerbate instability and even cause an explosion). Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a lithium battery cutting structure that solves the problem that the cut lithium battery body may become more unstable due to spring movement.

[0004] According to an embodiment of the present invention, a lithium battery cutting structure includes a pair of uprights and a crossbeam fixedly connected to the two uprights. A telescopic actuator is installed on the crossbeam. A cutter is disposed between the two uprights, located below the crossbeam and driven to move up and down by the telescopic actuator. A baffle is also fixedly connected between the two uprights, located below the cutter. The cutter has a blade that can abut against the baffle. A flexible baffle is also connected to the cutter, and the flexible baffle has a free end that can extend to below the top surface of the baffle.

[0005] In the above embodiment, the connected lithium battery cells enter the area below the crossbeam from the side without the flexible baffle. During the cutting process, the lithium battery cells abut against the flexible baffle. After cutting, the elastic force applied from behind pushes forward, while the flexible baffle blocks from above and presses downward. The lithium battery cells fall smoothly to the next process without being bounced to the ground, thus solving the problem in the prior art where the unstable state of the cut lithium battery cells may be aggravated by the bounce.

[0006] Furthermore, the baffle is also connected to a conveying plate located on one side of the two columns and a guide plate located on the other side of the two columns. The guide plate is located below the flexible baffle and is set at an angle downward.

[0007] Furthermore, the higher end of the guide plate is fixedly connected to the bottom surface of the baffle.

[0008] Furthermore, a step is recessed on the top surface of the baffle, and the step is close to the flexible baffle, so that the blade can abut against the step.

[0009] Furthermore, the cutter is recessed with a mounting groove, and a flexible baffle is fixedly connected to a mounting block that can be accommodated in the mounting groove. The flexible baffle and the mounting block are connected to the mounting groove by screws.

[0010] Furthermore, the telescopic actuator is fixedly installed on the top surface of the crossbeam, and the telescopic actuator has an output end that extends downward through the crossbeam and is fixedly connected to the cutter.

[0011] Furthermore, guide strips are fixedly connected to both sides of the cutter near the two columns, and guide grooves are recessed on the two crossbeams to allow the two guide strips to slide.

[0012] Furthermore, the upper and lower ends of the guide groove are located above and below the cutter, respectively.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] By setting a flexible baffle on the cutter to block and press down on the lithium battery body from above, the lithium battery body falls smoothly to the next process without being bounced to the ground. This solves the problem in the prior art where the cut lithium battery body may become more unstable due to the bounce. Attached Figure Description

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0022] In an exemplary implementation, such as Figure 1-3 As shown, this embodiment provides a lithium battery cutting structure, which includes a pair of columns 1 and a crossbeam 2 fixedly connected to the two columns 1. A telescopic actuator 3 is installed on the crossbeam 2. A cutter 4 is located below the crossbeam 2 and is driven to move up and down by the telescopic actuator 3 between the two columns 1. A baffle 5 is also fixedly connected between the two columns 1 and located below the cutter 4. The cutter 4 has a blade 6 that can abut against the baffle 5. The two columns 1 and the crossbeam 2 together form a U-shaped mounting frame similar to that in the prior art. The telescopic actuator 3 can be a hydraulic cylinder or a pneumatic cylinder, and has an output end 7 that extends downward to the bottom of the crossbeam 2 and is fixedly connected to the cutter 4, so as to drive the cutter 4 to move up and down. A flexible baffle 8 is also connected to the cutter 4, and the flexible baffle 8 has a free end that can extend to the bottom of the top surface of the baffle. The flexible baffle 8 can be a thin rubber strip, which is lightweight and will not put heavy pressure on the lithium battery body 9, while providing a limiting position from the upper side and a certain downward pressure.

[0023] In the above embodiment, the connected lithium battery body 9 enters the area below the crossbeam 2 from the side without the flexible baffle 8. During the cutting process, the lithium battery body 9 abuts against the flexible baffle 8. After cutting, the elastic force applied from behind pushes forward, while the flexible baffle 8 blocks from above and presses downward. The lithium battery body 9 falls smoothly to the next process without being bounced to the ground, thus solving the problem in the prior art where the cut lithium battery body 9 may become unstable due to the bounce. More specifically, the baffle 5 is also connected to a conveyor plate 10 located on one side of the two columns 1 and a guide plate 11 located on the other side of the two columns 1. The guide plate 11 is located below the flexible baffle 8 and is set diagonally downward. The conveyor plate 10 is used to send the lithium battery body 9 to be cut to the area below the cutter 4, while the guide plate 11 works with the flexible baffle 8 below to make the lithium battery body 9 transfer to the next process more smoothly.

[0024] like Figure 2 , 3 As shown, the higher end of the guide plate 11 is fixedly connected to the bottom surface of the baffle 5, so as not to affect the normal operation of the cutter 4. Specifically, a step 12 is recessed on the top surface of the baffle 5, and the step 12 is close to the flexible baffle 8. The blade 6 can abut against the step 12. When the cutter 4 moves downward, the blade 6 cuts the flexible packaging material 13 at the connection point, and the individual lithium battery body 9 is transferred downward to the next process.

[0025] like Figure 1 , 2 As shown, the cutter 4 is also recessed with a mounting groove 14. A flexible baffle 8 is fixedly connected to a mounting block 15 that can be accommodated in the mounting groove 14. The flexible baffle 8 and the mounting block 15 are connected to the mounting groove 14 by screws 16. The flexible baffle 8 installed in this way has better stability. More specifically, guide strips 17 are fixedly connected to both sides of the cutter 4 near the two columns 1. The two crossbeams 2 are also recessed with guide grooves 18 for the two guide strips 17 to slide. The guide strips 17 move in the guide grooves 18 as the cutter 4 moves, which ensures that the cutter 4 moves up and down more smoothly. More specifically, the upper end and the lower end of the guide groove 18 are located above and below the cutter 4, respectively, to provide sufficient force for normal guidance. At the same time, this also makes it convenient to add lubricant to the guide groove 18 to ensure smooth guidance.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
