Description

Technical Field

[0001] This utility model relates to the field of negative electrode film preparation technology, specifically to an AOI system for negative electrode film preparation. Background Technology

[0002] The negative electrode fabrication process significantly improves the battery's charge-discharge efficiency and rate performance by optimizing conductivity and reducing internal resistance, thereby enhancing the battery's cycle life and capacity stability. In addition, the dry electrode process ensures stable electrode performance, such as capacity retention, no gas generation, and extended lifespan. Lithium-copper composite negative electrode materials can effectively reduce the risk of thermal runaway and improve the safety of battery use. The dry electrode process avoids side reactions between solvent and electrolyte, further ensuring the stability and safety of electrode performance. The dry electrode process simplifies the manufacturing process, reduces solvent usage and recycling costs, and lowers overall capital and operating expenses. Furthermore, the dry electrode process overcomes the limitations of wet coating manufacturing processes on electrode thickness, making the preparation of ultra-thick electrodes possible and further optimizing electrode performance.

[0003] However, the traditional negative electrode fabrication process has the following drawbacks:

[0004] (1) Due to the process of applying sizing, pressing, scraping powder and drilling, the process is more than 10 meters long. Moreover, during the pressing process, the length of the negative electrode sheet is stretched, making it difficult to control the size of each negative electrode sheet.

[0005] (2) A small amount of dust will be generated during the manufacturing process of the negative electrode sheet. It will accumulate at the bottom over a long period of time, affecting the accuracy of AOI.

[0006] (3) Because the whole process is very long and involves multiple steps, the negative electrode sheet is prone to wrinkles and unevenness. Utility Model Content

[0007] The purpose of this invention is to provide an AOI system for the negative electrode sheet manufacturing process, to solve the problems mentioned in the background art, which are that the process requires sizing, thinning, powder scraping and drilling, and the total length of the process exceeds 10 meters. Moreover, during the thinning process, the length of the negative electrode sheet is stretched, making it difficult to control the size of each negative electrode sheet. During the manufacturing process of the negative electrode sheet, a small amount of dust is generated, which accumulates at the bottom over a long period of time, affecting the accuracy of AOI. Due to the long process and the multiple processes involved, the negative electrode sheet is prone to wrinkles and unevenness.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an AOI system for negative electrode sheet preparation, comprising a process frame, a sizing frame fixedly installed on one side of the top of the process frame, a vertical plate fixedly installed on the other side of the top of the process frame, a length guide rail fixedly installed on one side of the vertical plate on the process frame, a cutting component mounted on one side of the sizing frame at a height on the process frame, a liquid accumulation tank fixedly installed at the bottom of the inner wall of the sizing frame, a lifting cylinder fixedly installed at the top of the sizing frame, a sizing component fixedly installed at the movable end of the lifting cylinder, a rotating shaft rotatably connected to the middle of the inner wall of the sizing frame, a first clamping component fixedly installed at the middle of the rotating shaft, a drying edge-extending component penetrating the liquid accumulation tank fixedly installed on the process frame, a sliding block slidably connected to the middle of the length guide rail, and a second clamping component fixedly installed at the top of the sliding block.

[0009] Preferably, both the first clamping assembly and the second clamping assembly include a clamping platform and four limiting plates.

First displacement blocks are fixedly installed at both ends of the two clamping plates. The two first displacement blocks on one side are slidably connected to the first displacement rods. An opening is provided in the middle of the clamping platform. When the user rotates the lead screw, the threads on the surface of the lead screw match the threads on the inner wall of the positioning block. After the lead screw rotates, it pushes the clamping plates through the connecting seats. The clamping plates slide along the first displacement rods through the first displacement blocks. The two clamping plates clamp and fix the battery electrode plates from both sides.

[0010] Preferably, the bottom end of the clamping platform on the first clamping assembly is fixedly connected to the rotating shaft, and the bottom end of the clamping platform on the second clamping assembly is fixedly connected to the sliding block. The first clamping assembly is mounted on the rotating shaft via the clamping platform, and the second clamping assembly is mounted on the sliding block via the clamping platform.

The pump body's inlet is fixedly connected to an extraction pipe extending into the raw material tank, and the pump body's outlet is fixedly connected to a delivery hose extending into the raw material nozzle. The top of the lowering platform is fixedly connected to the movable end of the lifting cylinder. A micro motor that drives the second displacement rod to rotate is fixedly installed on the surface of one of the length plates. After the pump body is powered on, it starts and draws the sizing material from the raw material tank through the extraction pipe.

After the micro motor is powered on, it starts and drives the second displacement rod to rotate. The thread on the surface of the second displacement rod matches the thread on the inner wall of the second displacement block. The second displacement block is limited by the lifting platform that matches its shape and size, so the second displacement block slides along the second displacement rod to adjust the sizing position of the sizing roller on the battery electrode sheet. An external air supply device is connected to the gas spray head. After the battery electrode sheet is processed, the gas spray head sprays clean gas to clean the impurities adhering to it.

[0013] Preferably, the drying and edge-extending assembly includes a servo motor and a screw. The output end of the servo motor is fixedly connected to the bottom end of the screw. The top end of the screw is threadedly connected to a push shell that is slidably connected to a liquid accumulation tank. An mounting plate is fixedly installed on the top end of the push shell.

After the servo motor is powered on, it starts and drives the screw to rotate. The threads on the surface of the screw match the threads on the inner wall of the push shell. The push shell is limited by the liquid accumulation tank, so the push shell slides along the screw. The push shell pushes the mounting plate from the bottom to adjust the height of the heating plate and the edge-extending roller. After the heating plate is powered on, the heating wire inside the heating plate is powered on and heats up, drying the battery electrode sheets after sizing in the clamping assembly. The edge-extending roller performs edge-extending processing on the battery electrode sheets.

[0014] Preferably, a displacement cylinder is fixedly installed in the middle of the upright plate, and the movable end of the displacement cylinder is fixedly connected to the side of the sliding block facing it. A stepper motor for driving the rotating shaft is fixedly installed on the surface of the sizing machine frame. After the stepper motor is powered on, it starts and drives the rotating shaft to rotate, adjusting the direction of the battery electrode sheet fixed by the first clamping component. The displacement cylinder performs a telescopic movement, and pushes the sliding block from one side to slide along the length guide rail, adjusting the position of the battery electrode sheet clamped on the second clamping component.

[0015] Compared with the prior art, the beneficial effects of this utility model are: by setting up a drying edge extension component, a first clamping component, a second clamping component, a sizing component and a cutting component, the processing steps of the battery electrode sheet are modularized. Instead of taking pictures and monitoring the position of the electrode when the negative electrode is horizontal, the monitoring system is configured when the negative electrode sheet is vertical, which prevents the monitor from misjudging and improves the accuracy of battery electrode sheet processing.
