Technical Field

[0001] This utility model relates to the field of new energy battery electrode processing, specifically a new energy battery electrode cutting and conveying mechanism. Background Technology

[0002] With the rapid development of new energy technologies, new energy batteries are also undergoing continuous innovation. In new energy batteries, the electrode sheets establish electron transport channels through metal current collectors (aluminum foil / copper foil), while the active material layer and binder layer work together to maintain the mechanical strength of the electrode and prevent structural collapse during charging and discharging. The electrode sheets are composed of positive and negative conductive materials: the positive electrode uses lithium compounds such as lithium cobalt oxide, lithium iron phosphate, and ternary materials (such as lithium nickel cobalt manganese oxide), coated on the surface of aluminum foil; the negative electrode is mainly composed of graphite-based carbon materials, coated on copper foil, achieving stable lithium ion insertion and extraction through a layered structure. The electrode sheets, coated on the aluminum foil surface and in sheet form, are cut to the required size using a cutting machine. To facilitate transport and improve efficiency during cutting, an improved transport mechanism for cutting the electrode sheets was designed. Utility Model Content

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] Example 1

[0029] like Figures 1 to 4As shown, a new energy battery electrode sheet cutting and conveying mechanism is disclosed. This mechanism is used to transport and move the cut electrode sheets to prevent them from falling and affecting their function. The conveying mechanism includes a conveyor frame 1, with a conveyor bracket 2 mounted on the top of the frame 1. Conveyor belt brackets are mounted on the top of both sides of the conveyor bracket 2. An active conveyor roller is rotatably mounted at one end of each conveyor belt bracket, and a driven conveyor roller is rotatably mounted at the other end. The active and driven conveyor rollers are driven by a conveyor belt 3. A power conveyor roller for driving the conveyor belt 3 is mounted on the conveyor bracket. A power shaft passes through the power shaft, with one end of the power shaft rotating through one side of the conveyor bracket 2 via a bearing, and the other end of the power shaft rotating through the other side of the conveyor bracket 2 via a bearing. The end of the power shaft is connected to the output end of a drive motor 22 via a shaft connector. The drive motor 22 is fixedly connected to one side of the conveyor bracket 2 via a motor bracket.

[0030] Furthermore, the conveying power roller is positioned in the middle of the conveyor belt 3 and is used to drive the conveyor belt 3 to move; above the two sides of the conveying power roller, there are respectively a receiving power roller 21, and each receiving power roller 21 is connected to a receiving power shaft, and the two ends of the receiving power shaft are rotatably connected to the conveyor bracket 2 through bearings; the conveyor belt 3 passes through the two receiving power rollers 21 and the conveying power roller in an "S" shape. It should be noted that, based on the accompanying drawings, when the conveyor belt 3 passes under the two receiving power rollers 21 and the conveying power roller, the conveyor belt 3 first passes through one receiving power roller 21 with transmission friction, and then passes through the conveying power roller with transmission friction. At this time, the "receiving power roller 21 and the conveying power roller" pass in an "S" shape. Then the conveyor belt 3 passes through the other receiving power roller 21 with transmission friction. At this time, the "conveying power roller and the receiving power roller 21" pass in an "S" shape. This design, with the conveyor belt 3 passing through the two receiving power rollers 21 and the conveying power roller in an "S" shape, allows the conveyor belt 3 to be in a more "tight" state during transport, avoiding vibration during the transport process caused by the conveyor belt 3 being too loose, which could cause the cut electrode pieces on the conveyor belt 3 to fall off.

[0031] Example 2

[0032] Furthermore, an active conveyor shaft is threaded onto the active conveyor roller. One end of the active conveyor shaft passes through one of the conveyor belt brackets via a bearing, and the other end of the active conveyor shaft also passes through another conveyor belt bracket via a bearing. A passive conveyor shaft is threaded onto the passive conveyor roller. One end of the passive conveyor shaft passes through one of the conveyor belt brackets via a bearing, and the other end of the passive conveyor shaft also passes through another conveyor belt bracket via a bearing. Simultaneously, a sensing bracket 31 is provided above the conveyor belt 3. Several sensors are mounted and connected to the sensing bracket 31. These sensors are electrically connected to the controller 11, which is mounted and connected to the conveyor frame 1.

[0033] In this embodiment, the sensor on the sensing bracket 31 is electrically connected to the controller 11. If, during the conveying process, the cut electrode sheet falls off the conveyor belt 3, the sensor detects this and sends a feedback to the controller 11. At this time, the alarm connected to the controller 11 sounds an alarm to remind the operator that a drop has occurred. The operator picks up the fallen electrode sheet and collects it for inspection to avoid confusion with the cut electrode sheets on the conveyor belt 3 that have not fallen off, thereby affecting the quality of production and processing.

[0034] Example 3

[0035] Furthermore, a cutting mechanism is installed on the conveyor frame 1, and the cutting mechanism is located at one end of the conveyor belt 3. The cutting mechanism includes a lower cutting blade group 41 and an upper cutting blade group 42. The lower cutting blade group 41 is connected to the support base 411 through a lower blade holder. The bottom of the support base 411 is connected and fixed to the conveyor frame 1 by support rods around its perimeter. The upper cutting blade group 42 is located above the lower cutting blade group 41 and is movably arranged relative to the lower cutting blade group 41. It is used to cut the electrode sheet passing between the lower cutting blade group 41 and the upper cutting blade group 42. The upper cutting blade group 42 is connected to an active drive structure through an upper blade holder for driving the upper blade holder to move toward the lower cutting blade group 41.

[0036] The active drive structure of this setup includes an active seat 43 and a cutting cylinder 44. The active seat 43 is used to connect with the upper blade holder. Active guide rods 431 are respectively provided at both ends of the active seat 43. One end of the active guide rod 431 movably passes through the active seat 43 and is used to connect with the support base 411. The other end of the two active guide rods 431 is provided with end caps to prevent the active seat 43 from sliding out of the active guide rods 431. The cutting cylinder 44 is located above the active seat 43 and the conveying shaft of the cutting cylinder 44 is used to connect with the active seat 43. The cylinder body of the cutting cylinder 44 is used to connect with the top plate 441. The top plate 441 is used to connect with the support base 411 through a fixing rod.

[0037] Furthermore, a top support plate 5 for placing the electrode sheet to be cut is provided on the side of the support base 411 away from the conveyor belt 3. The top support plate 5 is used to connect with the support base 411. A push plate 51 is slidably adapted on the top support plate. One end of the push plate 51 is connected to the output end of the hydraulic telescopic rod. The extension and retraction of the hydraulic telescopic rod drives the push plate 51 to move, pushing the electrode sheet placed on the top support plate 51 toward the cutting mechanism. The cylinder of the hydraulic telescopic rod is used to connect and fix it to the conveyor frame 1 through the side bracket.

[0038] In this embodiment, the uncutable electrode sheet is placed on the top support plate 5; then, by controlling the hydraulic telescopic rod to drive the top surface of the push plate 51 to slide and adapt, the uncutable electrode sheet placed on the top support plate 5 passes through the cutting mechanism position; then, by controlling the cutting cylinder 44 to move downward, the upper cutting blade group 42 moves towards the lower cutting blade group 41, and the uncutable electrode sheet "pushed through" by the upper cutting blade group 42 and the lower cutting blade group 41 is "cut" into the required electrode sheet structure (small electrode sheet structure); and the cut electrode sheet is pushed into the surface of the conveyor belt 3, and the electrode sheet is transported to the other end of the conveyor belt 3 by the "friction" between the conveyor belt 3 and the electrode sheet. A special collection device is set at the other end of the conveyor belt 3 to collect the cut electrode sheets in a unified manner, which is then convenient for the next processing step.
