Description

Technical Field

[0001] The present invention relates to the technical field of battery disassembly and recycling, and specifically to a power battery recycling device. Background Art

[0002] The recycling of battery cells is an important link in the recycling process of lithium batteries. Through reasonable disassembly means, it is convenient to directly recycle the electrode sheets and diaphragms. Only the electrode sheets that do not meet the standards due to problems such as breakdown need to be directly crushed and recycled. When disassembling the batteries that need to recycle the electrode sheets and diaphragms, because it is necessary to avoid destructive disassembly and recycling, usually the battery is carefully disassembled manually and then the electrode sheets and diaphragms are recycled. Currently, in the recycling of power batteries, usually, after using a grinding machine to cut the battery case, the electrode sheets and diaphragms are manually taken out. It is not convenient to carry out live protection work. The method of manual direct cutting and disassembly has poor safety, is prone to electric shock injury, is not convenient for automatically adapting to rectangular batteries or cylindrical batteries for live operation protection work. At the same time, the manual cutting position is not accurate enough, and it is easy to accidentally touch and damage the electrode sheets and diaphragms. The recycling inspection of the electrode sheets and diaphragms usually relies on manual visual inspection, which is not convenient for automatically testing the breakdown damage of the electrode sheets and diaphragms. It is easy to miss inspections, and it is also not convenient to compulsorily scrap the broken-down electrode sheets and diaphragms. The damaged electrode sheets and diaphragms flowing into the recycling line will directly affect the battery yield.

At the same time, this structure can be used to detect the remaining battery power, which can prevent the staff from operating with electricity. While improving the safety of this structure, this structure can be adapted to discharge both rectangular batteries and cylindrical batteries at the same time, which can ensure the versatility of this structure when in use and be more suitable for the current battery disassembly work, preventing the problem that it is difficult to uniformly test the remaining power at different electrode terminal positions. The remaining power detection structure adopted by this structure is that the remaining power inside the battery may cause electric shock during the disassembly process, especially when contacting the internal conductor of the battery.

At this time, the end of the pressing switch 404 protruding and installed on the U-shaped frame 403 needs to be pressed against the upper edge of the battery to achieve the limit of the cutting height.

[0024] Embodiment 2, on the basis of Embodiment 1, the recycling and cleaning member 5 includes: a recycling and cleaning frame 501, a fixed power - connecting sponge 5011, a fitting shaft 502, a pressing block 503 and a movable power - connecting sponge 5031. The recycling and cleaning frame 501 is fixedly installed on the side of the lifting connection frame 101 by bolts; a fixed power - connecting sponge 5011 is fixedly embedded in the recycling and cleaning frame 501; two fitting shafts 502 are fixedly installed on the recycling and cleaning frame 501, and springs are sleeved on the two fitting shafts 502 respectively; a pressing block 503 is slidably installed on the two fitting shafts 502, and a movable power - connecting sponge 5031 is fixedly embedded in the pressing block 503; the springs on the fitting shafts 502 press against the pressing block 503; the movable power - connecting sponge 5031 and the fixed power - connecting sponge 5011 are connected in series to a power supply; conductive liquid is adsorbed on the movable power - connecting sponge 5031 and the fixed power - connecting sponge 5011; the length of the pressing block 503 is less than the width of the diaphragm; the recycling and cleaning member 5 further includes: a scrapped electromagnet 504 and a scrapped shaft 505. The magnetic force of the scrapped electromagnet 504 is greater than the magnetic force of the magnet at the tail of the scrapped shaft 505. The scrapped electromagnet 504 is fixedly installed inside the recycling and cleaning frame 501; a scrapped shaft 505 is slidably sleeved inside the recycling and cleaning frame 501, and the front end of the scrapped shaft 505 is conical; a magnet for magnetically attracting the side of the lifting connection frame 101 is provided at the tail of the scrapped shaft 505; an annular groove is provided on the outer side of the scrapped shaft 505; the scrapped shaft 505 passes through the fixed power - connecting sponge 5011; the middle of the scrapped electromagnet 504 passes through the scrapped shaft 505; the scrapped electromagnet 504 is used to magnetically attract the scrapped shaft 505; the scrapped electromagnet 504 is connected in series with the movable power - connecting sponge 5031 and the fixed power - connecting sponge 5011; the clamping and unwinding member 6 includes: unwinding clamping blocks 601 and elastic steel sheets 602. There are two unwinding clamping blocks 601, and the two unwinding clamping blocks 601 are used to bite and clamp the pole - piece diaphragm; the unwinding clamping blocks 601 are connected to the side of the recycling and cleaning frame 501 by elastic ropes;On the sides of two unwinding clamping blocks 601, elastic steel sheets 602 are fixedly installed. The recycling and cleaning part 5 can be used to clean the recycled electrode sheets and diaphragms, and can unwind the electrode sheets and diaphragms flatly. While facilitating subsequent surface treatment, this structure uses the fixed power - connecting sponge 5011 and the movable power - connecting sponge 5031, which can be used to test for defective breakdown and leakage problems. This can prevent the recycling of battery cells with insulation failures such as breaks, reduce the workload during subsequent detailed inspections, and also prevent the problem that the staff's detection is not thorough enough. It is easy to miss problems during visual inspection. At the same time, this structure can directly damage the electrode sheets and diaphragms with insulation failures, prevent the reuse of electrode sheets and diaphragms with insulation failures, avoid affecting the battery yield and increasing the subsequent workload, can be automatically controlled, and also prevent manual forgetting of classification, which affects the quality of battery recycling. The use of the clamping and unwinding part 6 can improve the flatness when unwinding and pulling out the electrode sheets and diaphragms. The electrode sheets and diaphragms are wiped and cleaned by the movable power - connecting sponge 5031 and the fixed power - connecting sponge 5011, and at the same time, the electrode sheets and diaphragms are assisted in being flattened. The ends of the electrode sheets and diaphragms are clamped by the unwinding clamping blocks 601 and manually clamped and pulled outwards. Since the width of the diaphragm is greater than the width of the electrode sheet, there is no need to detect the breakdown and leakage problems in the redundant position of the diaphragm. The length of the pressing block 503 can cover the electrode sheet area to test the insulation performance. At this time, as the electrode sheets and diaphragms move, if there are non - insulating areas such as defective breakdowns in the local areas of the electrode sheets and diaphragms, the conductive liquid between the movable power - connecting sponge 5031 and the fixed power - connecting sponge 5011 will be conducted. At this time, the waste electromagnet 504 will be energized to magnetically attract the waste shaft 505. The end of the waste shaft 505 can pierce into the electrode sheets and diaphragms. Using the annular groove on the outside of the waste shaft 505, it can be stuck into the electrode sheets and diaphragms. As the operator quickly pulls the unwinding clamping block 601 to drive the electrode sheets and diaphragms to move, the electrode sheets and diaphragms can be damaged and cut, preventing reuse.;

[0025] Working principle of this embodiment: First, when disassembling a cylindrical battery, the bottom of the cylindrical battery is attached to the suction cup 202 and the lower elastic piece 203. At this time, the top terminal of the cylindrical battery can be fitted to the positioning shaft 106. At this time, in cooperation with the sliding power connection sliding frame 201, it is ensured that the suction cup 202 is driven to move upward to clamp the battery. At this time, the positioning pin 107 can be pulled to drive the plug 108 to be inserted into the positioning groove on the power connection sliding frame 201 for limiting. At this time, the battery first presses against the positioning shaft 106, and then presses against the in-place switch 105 to detect that the battery is in place. Similarly, when disassembling a rectangular battery, the suction cup 202 is also driven to move upward to clamp the battery, and the positioning pin 107 is pulled to drive the plug 108 to be inserted into the positioning groove on the power connection sliding frame 201 for limiting. The position and quantity of the positioning grooves on the power connection sliding frame 201 can be set according to requirements. When the rectangular battery is clamped, its top positive and negative terminals can be respectively fitted by the strip-shaped dual-purpose piece 103. It is ensured that whether it is a rectangular or cylindrical battery, when there is a large amount of remaining electricity inside, the protection electromagnet 304 can be energized to magnetically attract the protection slider 302, and the series switch 303 will no longer be in contact with the side of the upper contact plate 102. It is necessary to ensure that when the series switch 303 is squeezed, the hand-held electric grinder 402 can be normally powered on and used, ensuring that while the battery is installed on the lifting connection frame 101, the battery can be disassembled normally only after being discharged. During actual operation, one hand of the staff needs to support the battery, and the other hand needs to hold the set hand-held electric grinder 402 and press its own switch in real time to keep it powered on. At this time, the end of the extrusion switch 404 installed on the U-shaped frame 403 needs to be pressed and fitted against the upper edge of the battery to achieve limiting, ensuring that the switch of the hand-held electric grinder 402 itself, the extrusion switch 404, the series switch 303, and the in-place switch 105 need to be powered on simultaneously to be normally used. After the hand-held electric grinder 402 cuts open the battery case, the positioning pin 107 can be pulled out, and the power connection sliding frame 201 and the suction cup 202 can be pulled down to assist in removing the lower half of the battery case. At this time, tools such as scissors can be used to cut the copper bus connecting the electrode sheet and the terminal, and then the wound electrode sheet and the separator can be passed through between the recycling and cleaning frame 501 and the pressing block 503, and wiped and cleaned by moving the power connection sponge 5031 and the fixed power connection sponge 5011. At the same time, the electrode sheet and the separator are assisted to be flattened. The ends of the electrode sheet and the separator are clamped by the unwinding clamp block 601, manually clamped and quickly pulled outwards. At this time, as the electrode sheet and the separator move, if there are non-insulated areas such as local defects and breakdowns in the electrode sheet and the separator, the conductive liquid between the moving power connection sponge 5031 and the fixed power connection sponge 5011 will be conducted. At this time, the waste electromagnet 504 will be energized to magnetically attract the waste shaft 505, and the end of the waste shaft 505 can pierce into the electrode sheet and the separator. As the unwinding clamp block 601 is quickly pulled by hand to drive the electrode sheet and the separator to move, the electrode sheet and the separator can be damaged and cut. As the subsequent electrode sheet and separator to be recycled are placed between the moving power connection sponge 5031 and the fixed power connection sponge 5011, the waste electromagnet 504 can be powered off.The magnet on the side of the scrapped shaft 505 will magnetically attract the side of the lifting connection frame 101 to achieve reset, ensuring that no damage will occur during the normal cleaning of the insulating electrode sheet and the diaphragm.
