Description

Technical Field

[0001] This utility model relates to the field of lithium battery manufacturing technology, and in particular to a cutting device for removing dust from a lithium battery stacking machine. Background Technology

[0002] In the manufacturing process of lithium batteries, the stacking machine is an important link. In the stacking process, the electrode sheets are cut by a cutter and then stacked in sequence to form a battery cell.

[0003] Currently, most domestic wafer stacking machines rely on the tight engagement of upper and lower cutters to complete the cutting process. Ideally, this engagement prevents dust and debris generation. However, due to factors such as cutter material, fatigue levels, and electrode manufacturing processes, filamentous debris and dust inevitably accumulate during electrode cutting. These debris and dust adhere to the electrodes and enter the next process, posing a serious risk of short circuits and failure. Existing cutter devices have a simple structure and lack timely dust removal capabilities, requiring periodic cleaning. Cleaning solutions are time-consuming and ineffective, failing to address the root cause of the problem. Furthermore, frequent disassembly can cause wear and tear on the cutter material, leading to other malfunctions. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology. In order to achieve the above purpose, a cutting device for cutting dust off a lithium battery stacking machine is adopted to solve the problems mentioned in the background technology.

The precise design of the cutting device ensures the accuracy and stability of the cutting, thereby improving product quality.

[0014] As a further aspect of this invention: the second cutter fixing mechanism is connected to the first cutter fixing mechanism via a guide rod. This guide rod connection enhances the structural strength of the cutter device, ensuring stability and safety during the cutting process.

[0015] As a further aspect of this invention: the dust removal assembly includes quick-connect duct connectors at the ends of the upper and lower cutters, an upper dust removal cutter vent on the upper cutter, a lower dust removal cutter vent on the lower cutter, a lower dust collection box on the side of the lower cutter, and a lower dust collection box vent at the end of the lower dust collection box. The meticulous design of the dust removal assembly effectively captures and removes dust generated during the cutting process, protecting the equipment and the working environment.

[0016] As a further aspect of this invention, the upper and lower cutting blades adopt a symmetrical structure. This symmetrical design is not only aesthetically pleasing but also ensures a uniform distribution of cutting force, improving cutting accuracy and efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0026] Please refer to Figure 1 In this embodiment of the present invention, a cutting device for removing dust from a lithium battery stacking machine includes:

[0027] Transmission components;

[0028] A drive assembly disposed at the end of the transmission assembly;

[0029] A cutting device disposed between the transmission components; and

[0030] A dust removal assembly is disposed on the side of the cutting device;

[0031] The drive component drives the transmission component to guide the electrode 2, the cutter device cuts the electrode 2, and the dust removal component simultaneously sucks up the dust.

[0032] In this embodiment, the drive assembly includes a front drive shaft 12 disposed on one side of the cutter device and a rear drive shaft 9 disposed on the other side of the cutter device.

[0033] In this embodiment, the transmission assembly includes a front belt 1 disposed circumferentially on the front drive shaft 12 and a rear belt 8 disposed circumferentially on the rear drive shaft 9.

[0034] In this embodiment, the cutting device includes a transmission screw 4, a first cutting tool fixing mechanism 5 disposed at the extension end of the transmission screw 4, an upper cutting tool 3 disposed on the side of the first cutting tool fixing mechanism 5, a second cutting tool fixing mechanism 10 disposed on the opposite side of the first cutting tool fixing mechanism 5, and a lower cutting tool 11 disposed on the side of the second cutting tool fixing mechanism 10.

[0035] like Figure 2 As shown, the diagram is a schematic diagram of the upper cutter structure;

[0036] like Figure 3 As shown, the diagram is a schematic diagram of the lower cutter structure;

[0037] In this embodiment, the second cutter fixing mechanism 10 is connected to the first cutter fixing mechanism 5 via a guide rod 6.

[0038] In this embodiment, the dust removal assembly includes a quick-connect duct connector 14 disposed at the ends of the upper cutter 3 and the lower cutter 11, an upper dust removal cutter air outlet 15 disposed at the upper cutter 3, a lower dust removal cutter air outlet 16 disposed at the lower cutter 11, a lower dust removal box 13 disposed on the side of the lower cutter 11, and a lower dust removal box air outlet 17 disposed at the end of the lower dust removal box 13.

[0040] In this embodiment, the upper cutter 3 and the lower cutter 11 adopt a symmetrical structure.

[0041] In this embodiment, the principle process is as follows:

[0042] ① Start the external vacuum fan. The function of the vacuum fan is to generate negative pressure suction to suck up the dust through the pipes for centralized processing.

[0043] ② The rear drive shaft 9 drives the rear belt 8 to rotate counterclockwise. The long electrode 7 on the rear belt 8 is conveyed from right to left to a certain distance below the upper cutter 3. At this time, the rear belt 8 stops.

[0044] ③ An external motor drives the transmission screw 4 to rotate. During the rotation of the transmission screw 4, the first cutter fixing mechanism 5 above moves up and down. When the first cutter fixing mechanism 5 moves up and down, it drives the upper cutter 3 to move up and down. The upper cutter 3 moves up and down and engages with the lower cutter 11 to complete the cutting action.

[0045] ④ During the cutting process, the debris and dust generated on the upper side of the electrode sheet are sucked away by the upper cutter 3 and discharged along the upper dust removal cutter air outlet 15 → air duct quick connector 14 → pipe → dust removal fan; the dust and debris generated on the lower side are sucked away by the lower dust removal cutter 11 and lower dust removal box 13 and discharged along the lower dust removal cutter air outlet 16 (lower dust removal box air outlet 17) → air duct quick connector 14 → pipe → dust removal fan.

[0046] ⑤ After the cutting action is completed, the front drive shaft 12 drives the front belt 1 to rotate counterclockwise. At this time, the electrode 2 on the belt 1 is transferred from right to left to the next process, and one cutting process is completed. This process is repeated.

[0047] ⑥ During the cutting process, the external dust removal fan is always on.
