Embodiment 1

[0069] Such as Figure 1~12 As shown, a device adapted to the dismantling of multi-standard prismatic lithium-ion batteries,

[0070] Including: a control system and an assembly line dismantling system, the dismantling system includes: an intermittent feeding device 1 sequentially fixed on a frame 6 built of square steel, a No. 1 automatic edge trimming device 2, and a station conversion Device 3, No. 2 automatic edge trimming device 4 and separation coring device 5; the control system controls and disassembles each part of the system for assembly line operation: the intermittent feeding device 1 transports the waste ion battery to No. 1 automated edge trimming Device 2, the No. 1 automatic trimming device 2 completes the trimming action on the symmetrical sides of the waste lithium-ion battery, and the station conversion device 3 rotates the trimmed waste lithium-ion battery by 90 degrees and transports it to the No. 2 automatic trimming device 4. No. 2 automatic trimming de...

Embodiment 2

[0101] A method of adapting to the dismantling of multi-standard prismatic lithium-ion batteries, using the device described in Embodiment 1 to adapt to the disassembly of multi-standard prismatic lithium-ion batteries, comprising the following steps:

[0102] 1) Place a batch of square waste lithium-ion batteries 9 containing different sizes and specifications directly into the figure 2 In the shown separate space of the feeding conveyor belt 8 provided with baffles, the feeding is carried out by the intermittent feeding control system in conjunction with the knife-cutting and dismantling speed;

[0103] 2) The waste lithium-ion battery first slides down through the feeding chute 7 onto the No. 1 distance-adjusting platform 14 in the No. 1 automatic trimming device 2, and the Figure 4 The distance measuring cylinder 10, the blocking cylinder 11 and the limit stop bar 12 in the feeding distance measuring device shown in the figure perform push positioning and distance measur...

Abstract

The invention discloses a device and a method for disassembling square lithium ion batteries of multiple specifications. The device comprises a control system and an assembly line type disassembling system. The assembly line type disassembling system comprises an intermittent feeding device (1), a first automatic edge cutting device (2), a station conversion device (3), a second automatic edge cutting device (4) and a separating and core taking device (5). The control system controls all parts of the disassembling system to conduct the assembly line type operation. The intermittent feeding device conveys waste lithium ion batteries to the first automatic edge cutting device to complete the edge cutting operation on the two symmetrical sides of the batteries. The station switching device rotates the cut batteries by 90 degrees and conveys the cut batteries to the second automatic edge cutting device to complete the edge cutting operation on the other two sides of the batteries. The separating and core taking device separates and collects upper and lower meter shells and battery cells. The lithium ion battery disassembling device is high in automation degree and high in adaptability.The discharging and safety problems in the lithium ion battery disassembling process are effectively guaranteed in a knife-cutting disassembling mode. The separation of a battery cell and a battery shell is achieved to the maximum extent.

Description

technical field [0001] The invention relates to the field of recycling and processing of lithium-ion batteries, in particular to a device and method for dismantling square lithium-ion batteries with multiple specifications. Background technique [0002] With the development of the economy and the progress of the society, mobile phones and other products have become necessities in people's lives, and the replacement rate of mobile phone products is accelerating. The lithium-ion batteries in a large number of scrapped mobile phone products have caused a lot of waste and brought troubled by environmental pollution. [0003] At present, my country has become the largest producer, consumer and exporter of lithium-ion batteries. At the same time, the waste of lithium-ion batteries is also showing explosive growth. It is estimated that by 2020, the total number of waste lithium-ion batteries will reach 25 billion. Therefore, various battery manufacturers It is also about to face hu...
