Description

Technical Field

[0001] The utility model relates to the field of battery testing equipment, in particular to a battery core testing and retesting device. Background Art

[0002] Battery cells are a crucial component of lithium-ion battery components, essentially the heart of the battery. Their production quality is highly demanding, and any surface defects can impact battery performance and safety. Battery cells are prone to defects like scratches and dents during the production process, so they undergo a visual inspection before shipment to ensure quality.

[0003] Battery cell visual inspection not only helps identify potential manufacturing defects and failures, but also improves production efficiency and product quality, ensures safety and reliability, and meets industry regulations and standards. These factors combine to make battery visual inspection an indispensable part of battery production, maintenance, and quality control.

[0004] Battery cell inspection is complex. Traditional visual inspection relies primarily on manual observation, which is not only inefficient but also results in high volatility and uncertainty. Using machine vision inspection equipment can significantly increase inspection speed and accuracy, thereby improving overall production efficiency.

[0005] For example, Chinese utility model patent CN117225729A discloses a battery appearance inspection device, including an end face inspection area and a side edge inspection area; both the end face inspection area and the side edge inspection area are equipped with a transport mechanism and a visual inspection device. The visual inspection device can inspect the appearance of the battery, and the qualified and unqualified batteries after inspection are sorted by a sorting mechanism. However, when the above-mentioned battery appearance inspection device performs an appearance inspection on the battery, each side of the battery is only inspected once to determine whether its appearance is qualified. There is no secondary detailed inspection of the battery appearance and no re-inspection of NG batteries. This will result in a lower battery qualification rate and affect the company's production efficiency. In addition, the battery appearance inspection device is relatively small in scale and cannot meet the needs of large-scale battery inspection lines. Utility Model Content

[0006] In order to solve the above problems, the utility model provides a battery cell detection and re-inspection device.

The cell front inspection component is used to detect whether there are defects on the front of the cells transported on the feeding conveyor. The large-surface inspection transfer and transplant component is used to transfer the cells that have passed the front inspection over the cell back inspection component and place them on the transfer placement platform. The cell back inspection component is used to detect whether there are defects on the back of the cells transferred by the large-surface inspection transfer and transplant component. The transfer placement platform is used to place the cells that have passed the rough inspection. One side of the transfer placement platform is provided with rough The conveyor belt for qualified battery cells, the conveyor belt for qualified battery cells in detailed inspection, the conveyor belt for NG battery cells and the conveyor belt for qualified battery cells in manual re-inspection are provided.

[0009] With this technical solution, after the battery cells are transferred from the infeed conveyor to the large-surface inspection assembly, they undergo a rough inspection, with the results determining their transfer location. If the appearance is normal, the rough inspection transfer and transplant assembly directly transfers the product from the transfer platform to the rough inspection qualified cell conveyor for transport to the next process step. If the rough inspection reveals surface damage, the transfer and transplant assembly transfers the cell to the detailed inspection conveyor. After passing the flip assembly, the robotic arm assembly conducts a detailed inspection of both surfaces. Once the detailed inspection passes, the transfer and transplant assembly transfers the cell to the qualified cell conveyor for transport to the next process step. If the detailed inspection still fails to meet the standards, the transfer and transplant assembly transfers the cell to the qualified cell conveyor for manual re-inspection. Passing cells are placed on the qualified cell conveyor, while failing cells are placed in a 'good' box on a custom cart for subsequent recycling. The products transported by the rough-inspection qualified battery cell conveyor belt, the detailed-inspection qualified battery cell conveyor belt and the manual-re-inspection qualified battery cell conveyor belt are transferred from the unloading transfer and transplanting assembly to the unloading conveyor belt and sent to the next process step.

During the transportation process, the battery cell back side is subjected to rough inspection by the battery cell back side inspection component 23. The battery cells that pass the rough inspection are transferred from the transfer placement platform 13 to the rough inspection qualified battery cell conveyor belt 12 through the rough inspection transfer and transplantation component 3. The battery cells that fail the rough inspection are transferred from the transfer placement platform 13 to the detailed inspection battery cell conveyor belt 15 through the transfer and transplantation component 4. Further detailed inspection is carried out by the robot arm component 6. The battery cells that need to be inspected in detail are turned over by the flipping component 7 so that the robot arm component 6 can perform detailed inspection on the back side of the battery cell. The qualified battery cells are transferred to the qualified battery cell conveyor belt 6 through the detailed inspection transfer and transplant component 5; the battery cells that fail the detailed inspection are transferred to the NG battery cell conveyor belt 17 through the detailed inspection transfer and transplant component 5, and then transferred to the manual re-inspection battery cell conveyor belt 19 through the NG transfer and transplant component 9 for manual re-inspection.

[0063] By performing a rough inspection and detailed inspection of battery cells before transferring them to manual re-inspection, the present invention effectively optimizes the workflow, rationally classifies battery cells, effectively distinguishes between qualified and unqualified products, significantly reduces manual operation, and saves time and costs. This significantly reduces the amount of manual involvement, effectively screening out unqualified products and improving production efficiency. The present invention only requires detailed inspection of products that fail rough inspection, which can improve inspection efficiency and the pass rate. Manual re-inspection of only products that fail detailed inspection can separate qualified products from unqualified products, reducing the scrap rate and improving production efficiency, while also reducing manual workload and saving time and costs.

[0064] The above is a further detailed description of the present invention in combination with specific implementation methods, and it cannot be determined that the specific implementation of the present invention is limited to this; for technical personnel in the technical fields to which the present invention belongs and related technical fields, based on the technical solution ideas of the present invention, the expansion and replacement of operating methods and data should all fall within the scope of protection of the present invention.
