[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. The following embodiments are used to illustrate this utility model but should not be used to limit its scope.

[0031] The following is combined Figure 1 This invention describes a live-line cutting device for battery cells, comprising:

[0032] The frame 1 has an insulating pad on its top surface and a liquid guide groove 101 below the insulating pad. The battery cell 5 is placed on the insulating pad.

[0033] The transmission mechanism is located on the top surface of the frame 1;

[0034] The cutting mechanism is driven and connected to the transmission mechanism. The cutting mechanism corresponds to the insulating pad. The transmission mechanism drives the cutting mechanism to move so that the cutting mechanism cuts the battery cell 5. The electrolyte flowing out after the battery cell 5 is cut falls into the liquid guiding tank 101.

[0035] An insulating pad is installed on the top surface of the frame 1 to ensure electrical safety during operation, effectively isolating the battery cell 5 from direct contact with the frame 1 and preventing short circuit risks. A liquid guiding groove 101 is installed below the insulating pad on the frame 1. This innovative feature allows the electrolyte flowing out after the battery cell 5 is cut to quickly and orderly fall into the liquid guiding groove 101, avoiding environmental pollution caused by random electrolyte flow and facilitating subsequent electrolyte recycling and treatment, reflecting the concepts of environmental protection and energy conservation. The transmission mechanism is located on the top surface of the frame 1. Its precise and stable transmission performance ensures that the cutting mechanism can move according to the predetermined trajectory and speed, which not only improves the cutting accuracy and efficiency but also greatly reduces the labor intensity of the operators. The cutting mechanism drive is connected to the transmission mechanism, corresponding to the position of the insulating pad. Through the precise drive of the transmission mechanism, the cutting mechanism can achieve rapid and accurate cutting of the battery cell 5. During this process, the electrolyte flowing out after the battery cell 5 is cut can be immediately collected by the liquid guiding tank 101, avoiding waste of electrolyte and potential harm to the environment.

[0036] In a preferred embodiment of the battery cell live-line cutting device of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the transmission mechanism includes several columns erected on the frame 1, a lead screw 205 that is horizontally rotatably connected to the columns and extends along the length of the insulating pad, and a rotating wheel 201 connected to the lead screw 205. The cutting mechanism is connected to the lead screw 205. By rotating the rotating wheel 201, the lead screw 205 is driven to rotate, thereby driving the cutting mechanism to move along the length of the insulating pad.

[0037] Preferably, the uprights are erected on the top surface of the frame 1, and the uprights are made of insulating material, which can be plastic.

[0038] Preferably, the column design ensures the stability and reliability of the transmission mechanism, spatially isolating the transmission mechanism and the battery cell 5 to prevent the current stored in the battery cell 5 from affecting the personal safety of the workers. The lead screw 205, as the core component of the transmission mechanism, enables the cutting mechanism to move smoothly and precisely along the length of the insulating pad, improving not only the cutting accuracy but also ensuring the stability and continuity of the cutting process. The connection between the rotating wheel 201 and the lead screw 205 realizes the key step of power transmission. The operator only needs to gently rotate the rotating wheel 201 to drive the cutting mechanism along a predetermined trajectory through the rotation of the lead screw 205. This design not only simplifies the operation process but also greatly improves work efficiency.

[0039] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the transmission mechanism also includes a first helical gear connected to the end of the lead screw 205, a second helical gear meshing with the first helical gear, and a drive rod connected to the second helical gear. The extension direction of the drive rod is perpendicular to the extension direction of the lead screw 205, and the rotating wheel 201 is connected to the drive rod.

[0040] Preferably, the first and second helical gears have a transmission housing 204 on their exterior. A coupling 203 is provided at the end of the drive rod extending out of the transmission housing 204. A column is provided at the bottom of the coupling 203. A bearing seat 206 is provided at the end of the lead screw 205 away from the first helical gear. The bearing seat 206 is located on the column. The coupling 203 is connected to the rotating wheel 201 through a transverse round rod 202. By rotating the rotating wheel 201, the transverse round rod 202 is driven to rotate, which in turn drives the second helical gear to rotate, thereby driving the first helical gear to rotate, which in turn drives the lead screw 205 to rotate, thus causing the cutting mechanism to move.

[0041] Furthermore, a slide rail 102 is provided on the top surface of the frame 1, and a slider is slidably mounted on the slide rail 102; the cutting mechanism includes a cutting frame connected to the lead screw 205 and the slider, and a cutter 31 with adjustable height mounted on the cutting frame. The cutter 31 is used to cut the battery cell 5. It is connected to the slider through the cutting frame, thereby ensuring the stability of the cutter 31 during its movement and ensuring that the cutter 31 can stably cut the battery cell 5.

[0042] Furthermore, the cutting frame is equipped with a cutting track extending along the height direction, and the cutting frame is equipped with a drive motor. The cutter 31 slides on the cutting track and is driven by the drive motor. Before placing the battery cell 5, the drive motor drives the cutter 31 to move upward along the cutting track, so that the operator can place the battery cell 5 on the insulating pad. Then, the drive motor drives the cutter 31 to move downward along the cutting track so that the cutter 31 corresponds to the battery cell 5, so as to facilitate cutting the battery cell 5.

[0043] Furthermore, the liquid guiding tank 101 includes a first liquid guiding section corresponding to the insulating pad and a second liquid guiding section connected to the first liquid guiding section and extending out of the frame 1. The slope of the first liquid guiding section is smaller than that of the second liquid guiding section so that the electrolyte generated during the cutting of the battery cell 5 can flow smoothly along the liquid guiding tank 101. The first liquid guiding section is located close to the insulating pad and its slope is designed to be relatively gentle to ensure that the electrolyte can be evenly distributed on the first liquid guiding section and avoid local accumulation of electrolyte. The second liquid guiding section is connected to the first liquid guiding section and quickly extends out of the frame 1 with a larger slope, which can accelerate the discharge of electrolyte and prevent electrolyte stagnation. This design not only ensures the effective collection of electrolyte, but also avoids the electrolyte from contaminating the inside of the liquid guiding tank 101, thereby improving the overall performance and safety of the battery cell live cutting device.

[0044] Furthermore, it also includes several sets of clamping components 4 disposed on the top surface of the frame 1 and corresponding to the insulating pad. The clamping components 4 are used to fix the battery cell 5 to the insulating pad. The clamping components 4 include clamping posts fixed to the top surface of the frame 1 and clamping rods screwed to the clamping posts and extending in the vertical direction.

[0045] Furthermore, a buffer insulating pad is provided at the bottom of the clamping rod. The buffer insulating pad is made of elastic material, which has good elasticity and wear resistance, and can effectively fix the battery cell 5 without damaging its surface. A limit block is provided at the top of the clamping rod to prevent the clamping rod from detaching from the clamping post. The clamping post is shaped like a 7, which makes it easy for the clamping rod to correspond to the top surface of the battery cell 5.

[0046] Preferably, when clamping the battery cell 5, the operator can rotate the clamping rod to gradually bring the buffer insulating pad closer to and adhere to the battery cell 5 until the battery cell 5 is firmly fixed to the insulating pad. This design not only improves the stability and accuracy of cutting the battery cell 5, but also greatly simplifies the operation process and improves work efficiency. At the same time, the number of clamping components 4 can be adjusted according to actual needs to adapt to the cutting requirements of different specifications of battery cells 5, further enhancing the flexibility and practicality of the live-lined battery cell cutting device.

[0047] Furthermore, the frame 1 includes a chassis, a support frame for erecting the chassis, and a top frame fixed to the top surface of the support frame. The top frame includes a rectangular frame and two horizontal beams fixed at intervals within the frame and arranged in parallel. An insulating pad is fixed to one of the horizontal beams, a slide rail 102 is provided on the other horizontal beam, a column is provided on the frame, and a liquid guide trough 101 is provided on the frame and the support frame.

[0048] Preferably, the insulating pad is disposed on an inclined surface that is inclined toward the cutting mechanism, and a limiting edge is provided on the edge of the insulating pad. The liquid guiding groove 101 corresponds to the edge of the insulating pad near the cutter 31, so that the electrolyte can smoothly enter the liquid guiding groove 101.

[0049] In one specific implementation, the drive motor drives the cutter 31 to move upward along the cutting track. The operator can rotate the clamping rod to move the buffer insulating pad away from the insulating pad plate. Then the operator places the battery cell 5 on the insulating pad plate. The operator can then rotate the clamping rod to make the buffer insulating pad gradually approach and fit the battery cell 5 until the battery cell 5 is firmly fixed on the insulating pad plate. A collection bucket can be placed at the end of the liquid guiding tank 101.

[0050] The drive motor drives the cutter 31 to move downward along the cutting track so that the cutter 31 corresponds to the battery cell 5. Then the operator rotates the rotating wheel 201 to drive the lead screw 205 to rotate, thereby driving the cutting mechanism to move along the length of the insulating pad, so that the cutter 31 cuts the battery cell 5. The electrolyte flowing out of the battery cell 5 enters the liquid guiding tank 101 and is collected by the liquid collection tank.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
