Description

Technical Field

[0002] As a crucial component connecting battery chips and battery modules, the cell flange plays a vital role in the field of new energy vehicle batteries. The cell flange is the interface connecting the battery chip and the battery module, used to transmit electrical energy and data signals. Its functions include battery chip fixing, sealing, and conductive contact. Cell flanges are widely used in the new energy vehicle battery field, thus affecting the vehicle's range and safety performance. Regarding battery chip fixing, the cell flange protects the mechanical strength of the battery chip and prevents external forces such as vibration from affecting it; regarding battery chip sealing, the cell flange prevents leakage of the battery chip and electrolyte, thereby improving battery safety; regarding conductive contact, the cell flange ensures the reliability of the connection between the cells inside the battery module, thereby improving the battery's performance indicators.

[0003] In battery manufacturing, one process involves cell flange cutting. The purpose of cell flange cutting is to remove excess parts of the cell flange to ensure subsequent cell assembly.

To ensure the quality of flange cutting and polishing, AOI inspection of the cell flange is required after polishing to screen and classify good and defective products in real time. Based on the above process requirements, it is necessary to design a cell AOI inspection machine. Utility Model Content

[0012] The beneficial effects of this utility model are as follows:

[0013] This utility model addresses the shortcomings and deficiencies of existing technologies by independently developing and designing an automatic AOI inspection machine for battery cells after flange cutting and grinding, as well as fully automatic loading, transfer, and unloading. This effectively improves the efficiency of battery cell AOI inspection and features flexible material handling, effectively reducing surface compression and deformation during battery cell transfer and ensuring battery cell quality during handling.

[0014] This utility model aims to provide an AOI automatic inspection process applied to the downstream process of battery cell flange cutting and grinding, which belongs to the downstream stage of battery cell production. Its function is to realize the AOI automatic inspection of battery cell flange after cutting and grinding, so as to classify and transfer defective and good products for storage, thereby improving the quality of battery cell production. Specifically, this utility model uses a horizontally arranged machine platform as its supporting structure. A cell platform is horizontally mounted on the machine platform, receiving the cells to be inspected from the previous workstation and transmitting them linearly backward. A detection linear module is mounted on the cell platform, driving a CCD lens connected to it to move linearly perpendicular to the cell platform for AOI inspection of the cells and adjusting the inspection position through linear movement. A transfer belt and a discharge belt are respectively located on both sides of the rear section of the cell platform.

A first lifting arm is mounted between the discharge belt and the cell platform, transferring the inspected cells from the platform to the discharge belt. In actual production, the transfer belt can store defective products after inspection, and the discharge belt can store good products after inspection, directly exporting the good products to the platform. The next workstation processes the cells, thus achieving automatic sorting and export of good and defective products. Furthermore, the first and second moving arms of this invention employ a flexible method for automatic cell handling, effectively preventing deformation of the cell surface during cell handling and ensuring cell quality. Specifically, the moving head of the first moving arm uses a moving cylinder to output linear power to drive the sliding block's lifting and lowering motion. A key feature is the horizontally extending first extension block at the top of the moving cylinder. A slidable moving support block on the outer wall of the sliding block is flexibly connected to the first extension block via a first spring post. The movable moving support block provides elastic cushioning via the first spring post. When the horizontally positioned moving suction block approaches the cell surface from above, the upward reaction force of the cell pushes the moving suction block and moving support block upwards for cushioning, achieving flexible contact between the moving suction block and the cell. This effectively prevents deformation of the cell surface during cell handling and improves cell quality. Attached Figure Description
