Dismounting device for fastening wedge-shaped plate and method

Abstract

The invention provides a dismounting device for a fastening wedge-shaped plate and a method. The dismounting device comprises a supporting assembly, a middle supporting seat, a movable pulling assembly, a small lifting hook and a large lifting hook; the supporting assembly is arranged on the upper end face of an opening of a battery shell body, and is used for supporting a device; the middle supporting seat is arranged in the interior of the supporting assembly; the movable pulling assembly is parallel to the middle supporting seat, is arranged in the interior of the supporting assembly and slides in the interior of the supporting assembly; the small lifting hook is connected to the bottom of the movable pulling assembly and used for being connected with a small wedge-shaped plate; and thelarge lifting hook is connected to the bottom of the movable pulling assembly and used for being connected with a large wedge-shaped plate. The device has the beneficial effects that the design of the large lifting hook and the small lifting hook is adopted, the device adapts to wedge-shaped plate structures in different forms, lightening holes in the wedge-shaped plates and the exposed end facesof the wedge-shaped plates are fully utilized and serve as force application and fixing fulcrums of the lifting hooks, and therefore the space occupied by the device is saved, and operation in a narrow space is facilitated.

Description

technical field [0001] The invention relates to the field of battery assembly and recycling, in particular to a disassembly device and method for fastening a wedge-shaped plate. Background technique [0002] With the rapid development of science and technology, the application range of batteries is becoming wider and wider. At the same time, the weight-specific energy and volume-specific energy indicators of the battery are getting higher and higher, that is, under the same battery energy, the smaller the weight and volume of the battery, the better. Then, in the design of the battery, under the condition of ensuring sufficient strength, the weight and volume of the fastening structural parts should be reduced as much as possible, so that the battery is light in weight, compact in structure, high in space utilization, and small in size. As a common fastening structure, the wedge plate is often used in battery assembly structures because of its small footprint, simple fasten...

Problems solved by technology

As a result, if it is necessary to disassemble the wedge-shaped plate, thereby eliminating the locking force of the wedge-shaped plate and releasing the fastening of the battery components, it will be limited because the wedge-shaped plate cannot exert a pull-out force opposite to its pressing direction, even if it is knocked Separation of fastened battery components by means of violent impacts such as vibration and vibration will also fail to complete smoothly due to the self-locking of wedge-shaped plates due to gravity, and may cause damage to other battery structures
