Description

A solid-state battery cell stacking machine and assembly method Technical Field

[0001] This invention relates to the technical field of solid-state battery cell production equipment, specifically to a solid-state battery cell stacking machine and assembly method. Background Technology

[0002] With the rapid development of the new energy industry, solid-state batteries have gradually become a research hotspot and development direction in the battery field due to their higher energy density, better safety, and longer cycle life. One of the core manufacturing processes of solid-state batteries is electrode stacking, and the stacking accuracy, stacking efficiency, and processing stability directly determine the cell performance and product qualification rate of solid-state batteries.

[0003] To improve the efficiency of battery cell processing, automatic stacking machines have been invented to achieve cell stacking. For example, application number CN202510660721.3 discloses an integrated stacking and thermal lamination machine, including a positive electrode die-cutting machine, a positive electrode thermal lamination machine, a negative electrode die-cutting machine, a single-sided negative electrode die-cutting machine, a stacking machine, a stacking hot-pressing testing machine, and a stacking tray loading and unloading machine. The positive electrode die-cutting machine is connected to the positive electrode thermal lamination machine. The positive electrode thermal lamination machine, the negative electrode die-cutting machine, and the single-sided negative electrode die-cutting machine are respectively connected to the stacking machine. The stacking machine is connected to the stacking hot-pressing testing machine. The hot-pressing inspection machine for battery cells is connected to the stacking and unloading machine. The advantages of this invention are as follows: the integrated equipment for cutting, stacking, hot-pressing, and gluing positive and negative electrode sheets of battery cells saves production time and manpower, and effectively improves production efficiency and finished product qualification rate; the die-cutting adopts the method of first cutting into sections, and then positioning by CCD to form multiple sheets in one die-cutting, resulting in less waste and high die-cutting accuracy of positive and negative electrode sheets; the hot-pressing machine for positive electrode adopts a flat-pressing method; the stacking machine stacks multiple sheets at one time, with high stacking efficiency and pressure maintenance throughout the stacking process; the hot-pressing inspection machine for stacking cells adopts a rotary gluing method. However, this stacking machine has the following problems: 1. During the production process of existing cells, when stacking positive and negative electrodes, due to differences in the size of the positive and negative electrodes or for the convenience of subsequent processing, there is a gap between the edges of the positive and negative electrodes. This gap can lead to tearing of the electrode edges and penetration of the solid electrolyte layer due to shear stress during subsequent hot pressing or other processing, resulting in defects in the all-solid-state battery structure. This further exacerbates short circuits and affects the electrochemical performance of the all-solid-state battery. The existing method is to fill the gap by applying glue, but this method suffers from uneven application, affecting the filling effect. Furthermore, the existing stamping and stacking hot lamination integrated machine does not have an edge filling function, requiring post-processing... 1. Continuous manual operation affects processing efficiency; 2. Existing stamping and stacking thermal lamination integrated machines use CCD positioning to die-cut multiple pieces in one go, but do not perform subsequent stacking and correction. During continued stacking, the vibration generated by the movement may cause the material position to shift, making it difficult to ensure the full-process attitude acquisition and closed-loop correction of multiple materials before loading, during handling, and after stacking. This makes it difficult to meet the stringent requirements of solid-state cells for interlayer alignment and affects the subsequent stacking quality; 3. The existing stamping and stacking thermal lamination integrated machines require manual transfer to independent testing equipment to detect the basic parameters of the cell materials, resulting in a lengthy production process that cannot meet the efficiency requirements of large-scale industrialization of solid-state cells.

After the thickness detection is completed, the first handling robot moves the battery cell material from the thickness detection component to the weighing device for weight detection. After the weight detection is completed, the first handling robot moves the completed battery cell material to the first temporary support component for temporary placement to prepare for unloading, thus completing the entire process.

[0015] Compared with the prior art, the above-mentioned one or more technical solutions in the insulating ring feeding and assembly device provided in the embodiments of the present invention have at least one of the following technical effects: 1. The present invention realizes the automatic feeding and assembly of the insulating ring by setting a third feeding device, which reduces the intensity of manual labor, ensures processing efficiency, and the third feeding device is used to stack the insulating ring material on the edge between the first electrode and the second electrode, which effectively avoids the tearing of the edge of the first electrode or the edge of the second electrode and the penetration of the solid electrolyte layer caused by shear stress during subsequent hot pressing and other processing, reduces the risk of short circuit, and significantly improves the structural integrity and electrochemical performance of the all-solid-state battery.

[0016] 2. By installing image acquisition components containing multiple image acquisition cameras on the sides of the first, second, and third feeding devices, real-time image acquisition and position feedback can be performed on the materials on the first platform of the first moving device and the materials on the racks of the first, second, and third feeding devices. This allows for coordinated control of the corresponding first and second sorting mechanisms for automatic adjustment and correction. Combined with the multi-directional folding mechanism on the first moving device, each layer of material can be pressed and positioned after placement, effectively preventing displacement and warping of the flexible electrode sheets and insulating rings during handling and subsequent processes. This ensures the alignment accuracy between each stack and the final battery cell, thereby improving the structural consistency and electrical performance of the battery cell. Furthermore, it reduces the number of material transfers between different devices and manual intervention, significantly improving production efficiency and cycle time, while reducing labor costs and operational complexity.

[0017] 3. By setting up a first handling robot, the automatic handling of battery cell materials after processing is realized. Combined with the thickness detection component to detect the thickness of the battery cell materials after processing, and the real-time screening of battery cell materials with abnormal weight by the weighing device, there is no need to manually transfer them to independent testing equipment for basic parameter testing of battery cell materials, thus shortening the production process and meeting the efficiency requirements of large-scale industrialization of solid-state batteries.

The first folding mechanism of the first moving device presses the first electrode material, and the first moving device drives the first electrode material to the third feeding device; S4. Loading of insulating ring material: The first moving device moves to below the third loading device. Another third clamp on the third loading device transports the corrected insulating ring material onto the first electrode material on the first placement platform and then resets. The first folding mechanism on the first moving device presses the insulating ring material onto the first electrode material. The first moving device then transports the stacked insulating ring material to the second loading device. S5. Loading of second electrode material: The first moving device moves to below the first loading device. Another second clamp on the second loading device... After the second electrode material is transported to the insulating ring material on the first placement platform and reset, the first folding mechanism on the first moving device presses the second electrode material onto the insulating ring material. The first moving device then transports the material after the second electrode is stacked to the first feeding device, repeating steps S3-S5 until it is stacked to a certain thickness and forms the battery cell material; S6. Transfer and hot pressing: The battery cell material formed by the stacking is moved towards the second moving device on the second frame under the transport of the first moving device. After it is moved into place, the second clamping mechanism on the second moving device clamps the first moving device. The battery cell material on the device is moved away, while the first moving device performs stacking processing on another battery cell material; after the second moving device moves closer to the hot pressing device, the rotating mechanism on the second moving device drives the battery cell material on the second clamping mechanism to rotate, and the second clamping mechanism moves the battery cell material to the hot pressing device for hot pressing processing, and the hot-pressed battery cell material is moved to the temporary placement mechanism or the pressing and positioning mechanism; S7. Adhesive application processing: the second clamp on the second moving device is oriented under the control of the rotating mechanism, and the battery cell material on the hot pressing device or the temporary placement mechanism is moved to the pressing and positioning mechanism. The battery cell material is fixed in the positioning mechanism. The adhesive applicator, driven by the fourth moving device, applies adhesive tape to the battery cell material in the positioning mechanism. Simultaneously, the first rotating mechanism drives the battery cell material to change its surface, cooperating with the adhesive applicator to complete the adhesive application process. After the adhesive application is completed, the adhesive applicator resets and enters a standby state under the drive of the fourth moving device. The third moving device controls the positioning mechanism to move towards the temporary support. After moving into position, the battery cell material is placed on the temporary support. The positioning mechanism resets under the control of the third moving device to process the next battery cell material; S8.Battery cell material inspection: The first handling robot moves the battery cell material, after adhesive application, from the temporary storage bracket to the thickness detection component for thickness detection. After thickness detection, the first handling robot moves the battery cell material from the thickness detection component to the weighing device for weight detection. After weight detection, the first handling robot moves the completed battery cell material to the first temporary storage component for temporary storage, ready for unloading, thus preparing for the next battery cell material. The entire process is then complete.
