Machine to place groove for cylindrical (18650) lithium-ion secondary batteries etc.

Overview

Machine to place groove for cylindrical (18650) lithium-ion secondary batteries and similar items used in the manufacturing process of lithium-ion batteries. It is designed to respond to various battery sizes and line tact, and manual machines are available for laboratory use. The system incorporates battery material handling approaches that allow electrodes to be handled at high speed without causing damage to fragile active material and includes measures to prevent generation of precipitation and corrosion gas in electrolytes. For applications targeting a tact time less than 1 second, a cam mechanism is used to address synchronization and long-term stability issues encountered with cylinder or AC servo actuators, with driving held by a minimal motor. The machine platform emphasizes a strong mounting and base—eliminating aluminum frames and using thick square logs and a substantial base for can manufacturing, with options for annealing and mounts with additional accuracy—and integrates precise positioning through alignment systems, image processing, and mounting design; image processing capabilities include positioning, missing-part and scratch detection and continuous image processing of long objects using a licenser camera. Additional features include assembly practices aimed at long-term accuracy retention, measures for operation in ultra low humidity (dry room) environments including considerations for lubricants and static electricity, safety technology and support for safety PLC, and procedures to maintain cleanliness tailored to battery manufacturing rather than semiconductor-level cleanrooms (normal clean rooms protect against contamination of 0.5 μm). Used in the production process to place grooves on cylindrical (18650) lithium-ion secondary batteries and similar items, with options to accommodate various battery sizes and production takt. Manual versions support laboratory use. The machine is applicable where high-speed, non-damaging handling of fragile electrode materials and control of electrolyte-related precipitation and corrosion gas are required, and it can be configured for ultra low humidity dry-room environments, customized cleanliness levels for battery manufacturing, and safety PLC integration.
