Description

Technical Field

[0001] The utility model relates to the technical field of electrode sheet production, in particular to a slitting device for battery electrode sheet production. Background Technique

[0002] Battery electrode sheets are key components in batteries and play an important role in the electrochemical reactions of batteries. There are mainly two types of battery electrode sheets: positive electrode sheets and negative electrode sheets. The positive electrode sheet is the part where oxidation reaction occurs in the battery and is usually made of materials with high electrochemical activity. During charging, it releases electrons and generates positive charges. The negative electrode sheet is the part where reduction reaction occurs in the battery and is usually made of materials with high electrical conductivity and reduction performance. During charging, it accepts electrons and generates negative charges. The capacity of the electrode sheet determines the energy storage capacity of the battery, and the capacity is usually expressed in ampere-hours or milliampere-hours. The conductivity of the electrode sheet affects the power output and charge-discharge efficiency of the battery. Good conductivity can reduce the internal resistance and improve the battery performance. The design and material selection of battery electrode sheets have an important impact on the overall performance of the battery, so careful consideration is required during the battery manufacturing process.

[0003] After the electrode sheets are prepared, they need to be slit into required strip-shaped bodies on a slitting device, and then the cut electrode sheets are wound by a winding roller. When the existing slitting device for battery electrode sheet production is in use, there is no guiding and limiting for the electrode sheets, resulting in easy deviation of the electrode sheets during cutting and winding, affecting the production quality. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that during use, there is no guiding and limiting for the electrode sheets, resulting in easy deviation of the electrode sheets during cutting and winding, affecting the production quality, and to provide a slitting device for battery electrode sheet production.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

It further includes: a limiting plate with a "concave" structure for guiding the transportation of the electrode sheet; a limiting rod fixedly connected above the base, and two symmetrically arranged sliders are slidably installed on the limiting rod, and the two limiting plates are respectively fixedly connected to the tops of the two sliders. Among them, a driving part for driving the two sliders to move relative to each other along the limiting rod is provided on the base.

[0013] 1.

[0022] Embodiment:

[0023] Referring to Figures 1-4 , the embodiment of the present utility model provides a battery electrode sheet production and slitting device, including a base 1, a winding roller 4 and a blade 5. The winding roller 4 and the blade 5 are both installed above the base 1, and further include: a limit plate 201 in a "concave" shape structure for guiding the transportation of the electrode sheet; a limit rod 202 fixedly connected above the base 1, and two symmetrically arranged sliders 203 are slidably installed on the limit rod 202. Two limit plates 201 are respectively fixedly connected to the tops of the two sliders 203. Among them, a driving part for driving the two sliders 203 to move relative to each other along the limit rod 202 is provided on the base 1. One end of the electrode sheet is wound on the conveying roller, and the other end is wound on the winding roller 4. The conveying roller is used for conveying the electrode sheet, and the blade 5 is used for cutting the electrode sheet.

[0024] Specifically, the driving unit drives the two sliders 203 to slide along the limiting rod 202 and approach each other, thereby driving the two limiting plates 201 to move synchronously until the limiting plates 201 contact the edge of the electrode sheet, thereby guiding and limiting the electrode sheet to prevent deviation during the cutting and winding process, thereby improving production quality.

[0025] The driving unit includes a first motor 204 fixedly connected to the base 1. The output end of the first motor 204 is fixedly connected to a bidirectional screw rod 205. Both sliders 203 are threadedly connected to the bidirectional screw rod 205. The first motor 204 is electrically connected to an external power supply.

[0026] Specifically, the first motor 204 is started, and its output end drives the bidirectional screw rod 205 to rotate, and under the restriction of the limit rod 202, drives the two sliders 203 to slide relative to each other.

[0027] A second motor 6 is fixedly connected to the base 1, and the winding roller 4 is transmission-connected to the output end of the second motor 6. A rotating shaft 7 is rotatably mounted on the base 1, and the blade 5 is fixedly connected to the rotating shaft 7. A belt 8 is transmission-connected between the rotating shaft 7 and the output end of the second motor 6, and the second motor 6 is electrically connected to an external power supply.

[0028] Specifically, the second motor 6 is started, and the output end of the second motor 6 drives the winding roller 4 to rotate to reel in the cut electrode sheet. At the same time, the belt 8 and the rotating shaft 7 drive the blade 5 to rotate to perform cutting.

[0029] A fixed plate 9 is fixedly connected to the base 1, and a connecting rod 10 is slidably installed on the fixed plate 9. An arc-shaped baffle 12 is fixedly connected to one end of the connecting rod 10 close to the winding roller 4. The arc-shaped baffle 12 is opposite to the winding roller 4. The other end of the connecting rod 10 is fixedly connected to a limiting block 11, and a spring 13 is fixedly connected between the arc-shaped baffle 12 and the fixed plate 9.

[0030] Specifically, during the winding process, the arc baffle 12 contacts the electrode sheet on the winding roller 4. As more and more electrode sheets are wound, the electrode sheets squeeze the arc baffle 12 to compress the spring 13, so that the arc baffle 12 is always in contact with the electrode sheet, and the collection is not loose but tighter, which improves the winding quality. The connecting rod 10 is used to support the arc baffle 12 and limit it. The limit block 11 is used to limit the connecting rod 10 to prevent the connecting rod 10 and the arc baffle 12 from falling from the fixed plate 9.

[0031] The top of the base 1 is fixedly connected with a slide rail 301. A sliding block 302 is slidably mounted on the slide rail 301. An installation plate 303 is fixedly connected to the sliding block 302. A brush 304 is fixedly connected to the bottom of the installation plate 303. A first connecting plate 305 is fixedly connected to the rotating shaft 7. A second connecting plate 306 is rotatably connected to the first connecting plate 305. The second connecting plate 306 is rotatably connected to the sliding block 302.

[0032] Specifically, during the cutting process, the generated debris falls on the base 1. When the rotating shaft 7 rotates, it will drive the sliding block 302 to slide along the slide rail 301 through the transmission of the first connecting plate 305 and the second connecting plate 306. Furthermore, it will drive the brush 304 to move on the base 1 through the installation plate 303, brushing off the debris on the base 1 and making the tabletop cleaner.

[0033] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
