Background

The clamp trolley for baking the batteries has a multi-layer laminate structure, the batteries are placed above the laminates, and the batteries are automatically moved from the material taking positions to each layer of laminate through the feeding and discharging mechanism. The existing mode is that a hooking machine module is used for lifting a layer plate on the upper layer to a certain height, so that the upper layer plate and a layer plate on the lower layer are separated, and then a battery taking mechanism utilizes a vacancy between the layer plates to place a battery. The problems of the laminated plate extraction method are as follows: because the hooking module needs to be staggered with the battery taking mechanism in the height direction, the hooking module is installed above the battery taking mechanism, and the hooking module needs to have a certain stroke to realize the lifting of the bottom layer plate.
