Resumen de: EP4624376A1
The present application relates to a material storage apparatus, a battery assembly system and control method, and a battery production system, in which a first sensing assembly is disposed on the storage bin, and the first sensing assembly is configured to determine whether the assembly apparatus enters the discharging port. When the material storage apparatus does not receive a material discharging instruction, the first sensing assembly is in an activated state, and continuously monitors whether the assembly apparatus enters the discharging port; if detected, the first sensing assembly feeds back a corresponding signal to the control module, and the control module then controls the assembly apparatus to halt, so as to restrict the assembly apparatus from mistakenly entering the accommodating cavity. In this case, material feeding operations can be performed at the feeding port, that is, materials can enter the accommodating cavity through the feeding port for accommodation, thereby achieving safe material feeding. When the material storage apparatus receives the material discharging instruction, the first sensing assembly is in a deactivated state, and in this case, the assembly apparatus can smoothly enter the accommodating cavity through the discharging port for material pickup. This design does not require a dedicated one-to-one space configuration, thereby reducing space occupation, increasing space utilization rate, and lowering assembly cost.
