Description

TECHNICAL FIELD

[0001] The utility model relates to a retired power battery disassembling technology and belongs to the field of green environmental protection technology, in particular to a retired power battery disassembling device and system. BACKGROUND

[0002] In the disassembly or stepwise utilization of the retired power battery, the battery module needs to be disassembled from the battery package shell and then tested. In order to ensure the safety of the battery, a certain amount of potting glue is added to the bottom of the shell after the battery module of the retired power battery is assembled into the battery package shell. The potting glue is between the module and the bottom of the shell and between the modules. Because the potting glue has very good adhesion, it is difficult to safely remove the battery module from the battery package in the stepwise utilization of the power battery.

[0003] There are two methods to solve this problem at present.

[0004] 1. Add sol, dissolve the potting glue by chemical method, and then take out the battery module. The disadvantage is that the sol has a pungent smell, which has hidden dangers to personal health and environmental pollution.

[0005] 2. Take out after freezing for more than 4 hours in an environment below-35 DEG C. The disadvantage is that condensate appears on the surface of the battery module in the normal temperature environment after the frozen battery module is taken out, which causes great safety hazards to the battery.

[0006] Therefore, the prior art has defects and needs to be improved. CONTENT OF THE UTILITY MODEL

The saw cutting motor 14 is fixed on the sliding table 26. The saw cutting motor 14 drives the saw blade 16 to rotate. The stepper motor 27 drives the sliding table 26 to move along the track 25. The saw cutting motor 14 moves along with the sliding table 26. The rotating saw blade 16 moves along the platform slot 13 to cut off the battery pack side plate;

[0030] The battery pack is placed between the limiting piece and the cylinder and is pressed tightly. The stepper motor 27 drives the sliding table 26 to move in the front and back direction of the fixed platform. The saw cutting motor 14 is installed on the sliding table 26, and the saw blade 16 is installed on the motor. The stepper motor works, drives the sliding table 26 to move, drives the saw cutting motor to move, and the saw cutting motor drives the saw blade to work to cut off the side plate of the battery pack.

[0031] The platform slot 13 is arranged on one side of the fixed platform. The length of the platform slot 13 is greater than the length of the battery pack, so as to pass the saw blade when the saw cutting motor moves;

[0032] The jacking cylinder and the limiting piece installed on the fixed platform are used. The position of the limiting piece and the stroke and installation position of the jacking cylinder are adjusted to adapt to battery packs of various sizes.

[0033] The sliding table module is installed below the fixed platform, the moving direction of the sliding table 26 is the front-back direction of the platform, the sliding table can slide along the front-back direction of the platform under the driving of the stepping motor 27, and the advancing and retreating of the sawing motor are guaranteed.

[0034] The folding equipment comprises a base 20, a sliding platform 21, a linear motor, a portal frame 22, a pressing oil cylinder 23 and a stretching oil cylinder 24.

[0035] The upper surface of the base is provided with a guide groove for supporting and guiding the front-back movement of the sliding platform 21.

[0036] The lower surface of the sliding platform is provided with a guide rail which cooperates with the guide groove on the upper surface of the base to ensure the movement of the sliding platform along the guide groove of the base.

[0037] The upper surface of the sliding platform is provided with a plurality of insulating plates for supporting the safety of the battery pack module disassembly.

[0038] The portal frame is provided with two groups of oil cylinders, one group being the left-right arranged pressing oil cylinders and the other group being the front-back arranged stretching oil cylinders.

[0039] The cylinder barrel of the pressing oil cylinder 23 is connected with the portal frame, the piston rod head is fastened with the pressing rod, the up-down movement of the piston rod of the pressing oil cylinder drives the up-down movement of the pressing rod, thereby pressing and loosening the battery pack.

[0040] The cylinder barrel of the stretching oil cylinder 24 is hinged with the portal frame through a hinge shaft ring, the piston rod head is connected with a hook, the hook is connected with the front (rear) side plate of the battery pack shell through a steel wire rope, when the stretching oil cylinder is stretched, the opposite side plate is subjected to a pulling force obliquely upward, and the angle can be adjusted arbitrarily to stretch the side plate obliquely upward.

[0041] The battery pack with both sides of the side plates cut off by the cutting device is placed on the sliding platform, with the battery modules facing downward and the battery pack shell facing upward. The remaining two side plates of the battery pack are placed in the front-rear direction on the sliding platform. The linear motor is started to drive the sliding platform, so that the second column of modules in the battery pack is located below the pressing rod. The hydraulic system is started to drive the pressing cylinder piston rod to extend, and then the stretching cylinder piston rod is driven to extend, so as to fasten the steel wire rope hung on the stretching cylinder rod head to the front side shell of the module. The stretching cylinder piston rod is driven to retract, so as to stretch the battery pack shell upward (obliquely upward). The shell is deformed under the action of the pressing force and the stretching force, and is locally folded upward, so that the first column of modules and the second column of modules are separated from each other by overcoming the adhesion of the pouring sealant therebetween. Then, the pressing cylinder piston rod is retracted, the linear motor is operated, and the sliding platform is moved forward by a module distance. The pressing cylinder piston rod is extended to press the third column of modules, and the above-mentioned operation is repeated to separate the pouring sealant between the second column of modules and the third column of modules. The above-mentioned operation is sequentially performed to separate the modules in the front half of the battery pack. At this time, the pressing cylinder piston rod is retracted, the linear motor is operated, and the sliding platform is moved forward to the second column of modules in the rear half of the battery pack being located below the pressing rod. The above-mentioned operation is repeated to press the modules, drive the rear stretching cylinder piston rod to extend, fasten the steel wire rope hung on the stretching cylinder rod head to the rear side shell of the battery pack, drive the stretching cylinder piston rod to retract, stretch the battery pack shell upward (obliquely upward), and deform the shell under the action of the pressing force and the stretching force. The above-mentioned operation is repeated to fold the modules in the rear half of the battery pack, so that the battery pack shell is deformed from the original planar shape into a polygonal shape. At this time, the modules and the battery pack shell are only connected by the pouring sealant at the bottom. Since the connection surface between the modules and the shell is an open surface, the modules can be removed from the shell by using a blade or the like. Subsequently, the modules are normally operated on the module gradient production line.
