Description

Technical Field

[0001] The utility model relates to the technical field of lithium batteries, and in particular to a lithium battery pole piece cutting device. Background Art

[0002] Lithium batteries are batteries with lithium metal as the negative electrode, also known as lithium metal batteries. Lithium batteries are used in many long-life key devices, and lithium batteries can also replace ordinary alkaline batteries in many devices. In the production process of sodium-ion batteries, cutting devices are required to cut electrode sheets, which are important components of sodium-ion batteries.

[0003] The existing electrode sheet is rolled up before cutting. When cutting, the rolled electrode sheet needs to be pulled out to a certain length and then cut horizontally. At this time, the electrode sheet is still in a bent state. The existing cutting device lacks a flattening mechanism for the electrode sheet, which makes cutting inconvenient and may cause cutting errors. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the above technical difficulties and provide a lithium battery electrode sheet cutting device which can flatten the lithium battery electrode sheet when cutting it.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is:

[0006] A lithium battery pole piece cutting device, comprising:

[0007] A workbench, with a winding roller arranged on the top right side, on which an electrode sheet is wound;

[0008] The pressure plate is liftable and arranged on the top left side of the workbench;

[0009] The flattening roller is rotatably arranged between a pair of moving blocks. A horizontal moving driving mechanism is arranged on the upper side of the workbench. The two moving blocks are driven to move horizontally on the upper side of the workbench by the horizontal moving driving mechanism. The horizontal moving driving mechanism includes a threaded rod 1, a guide rod 1 and a driving motor 1. The threaded rod 1 is rotatably arranged on the top rear side of the workbench. The driving motor 1 is installed on the upper side of the workbench, and the output shaft is connected to the right end of the threaded rod 1. The guide rod 1 is fixed on the top front side of the workbench and is symmetrically arranged with the threaded rod 1 along the middle of the workbench. The two moving blocks are respectively threadedly sleeved on the threaded rod 1 or movably sleeved on the guide rod 1. The driving motor 1 can drive the threaded rod 1 to rotate, so that the moving block can move in the horizontal direction, so that the flattening roller can move horizontally on the workbench to flatten the pulled electrode sheet from left to right;

[0010] The cutting mechanism is arranged above the workbench and can move left and right and forward and backward.

[0011] As an improvement, a pair of support plates are symmetrically arranged on the left side of the top of the workbench. The support plate is an inverted L-shaped structure, and an electric telescopic rod is fixed on the lower side of the horizontal plate part. The front and rear ends of the pressing plate are respectively fixed to the lower side of the piston shaft end of the electric telescopic rod on the same side. The electric telescopic rod can push the pressing plate to move downward and press the left end of the electrode sheet onto the workbench.

[0012] As an improvement, through slots are respectively provided on the front and rear sides of the workbench, and an inverted U-shaped moving frame is provided on the upper side of the workbench. The bottom ends of the front and rear sides of the moving frame pass through the through slots respectively and are movably installed on the inner side of the through slots. A threaded rod 2 is rotatably provided on the lower side of one of the through slots, and a guide rod 2 is fixed on the lower side of the other through slot. A driving motor 2 is installed on the lower side of the workbench, and the driving motor 2 drives the threaded rod 2 to rotate. The two bottom ends of the moving frame are respectively threadedly sleeved on the threaded rod 2 or movably sleeved on the guide rod 2, and the cutting mechanism is provided on the inner top of the moving frame. The driving motor 2 can drive the threaded rod 2 to rotate, thereby driving the moving frame to move in the left and right directions, thereby changing the placement position of the moving frame, and thus changing the cutting position of the cutting mechanism.

[0013] As an improvement, the cutting mechanism includes a movable block, a multi-stage telescopic rod and a cutting knife. The inner top of the movable frame is rotatably provided with a threaded rod three, and a guide rod three is fixed thereto. A driving motor three is installed on one side of the top of the movable frame. The output shaft of the driving motor three is connected to the threaded rod three. The movable block is threadedly sleeved on the threaded rod three and movably sleeved on the guide rod three. The top of the cutting knife is connected to the bottom of the movable block through the multi-stage telescopic rod. The driving motor three can drive the movable block to move forward and backward on the movable frame, and can drive the cutting knife to move, thereby completing the cutting of the electrode sheet.

[0014] As an improvement, support legs are respectively fixed at the bottom corners of the workbench.

[0015] The advantages of the utility model compared with the prior art are: by providing a lifting and lowering pressure plate and a flattening roller that can move horizontally on the workbench, the utility model can press the left end of the electrode sheet against the workbench through the pressure plate when the rolled electrode sheet is pulled out, and flatten the bent electrode sheet from left to right by moving the flattening roller, thereby facilitating subsequent cutting.
