Description

Technical Field

[0001] This application relates to the field of specialized conveyor technology, and in particular to a disassembly and conveying device for preventing voltage rebound during lithium battery discharge. Background Technology

[0002] Dismantling end-of-life lithium batteries is a high-tech process integrating safety, environmental protection, and resource recycling. It is an industry currently encouraged by the state for resource recycling. Large-scale production generally includes steps such as deep discharge, crushing and pulverizing, sorting, electrode material recovery, and hydrometallurgy. Even after a lithium battery is "depleted" or "scrapped," it still retains a considerable amount of residual energy. If it is not discharged, it is highly susceptible to short circuits, arcing, and explosions during subsequent mechanical processing such as crushing, cutting, and compression.

[0003] The discharge process of discarded lithium batteries is generally carried out by immersion in a conductive salt solution. The essence of salt solution discharge is to construct an external, ion-conducting closed circuit to replace the internal electronic circuit of the battery, thereby orderly consuming the battery's residual electrical energy. However, due to the voltage rebound characteristic of lithium batteries, when the lithium battery finishes discharging and is transported to the next cutting stage, the voltage of the lithium battery will slowly rebound. During subsequent cutting, the lithium battery voltage has rebounded to a certain extent. Cutting a lithium battery with a rebounding voltage while it is energized can cause fires, explosions, and other situations, posing a great threat to safe production. Summary of the Invention

[0004] This application proposes a disassembly and conveying device for preventing voltage rebound during lithium battery discharge. It has the advantage of preventing voltage rebound during the conveying of discharged lithium batteries, thereby solving the problem of voltage rebound during the conveying of discharged lithium batteries, which can lead to fire, combustion, and explosion during cutting.

[0005] To achieve the above objectives, this application adopts the following technical solution: a disassembly and conveying device for preventing voltage rebound during lithium battery discharge, comprising a bracket, side baffles, a chain plate drive wheel, a chain plate driven wheel, and a reduction motor. A transmission chain plate is sleeved on the outer side of the chain plate drive wheel and the chain plate driven wheel. The transmission chain plate is ring-shaped and consists of multiple single chain plates hinged end to end. A chain is fixedly installed on the inner ring of the transmission chain plate, and the chain on the inner ring of the transmission chain plate meshes with the chain plate drive wheel and the chain plate driven wheel for transmission. A liquid removal mechanism for wiping the lithium battery tabs is fixedly installed at the middle position of the outer side wall of the single chain plate.

[0006] Furthermore, the bottom end of the bracket is threaded with several adjustable feet, and galvanized flat iron is welded onto the bracket for effective grounding.

[0007] Furthermore, a vertical baffle is fixedly connected to one side of the top of the single chain plate, and the plane of the vertical baffle is perpendicular to the plane of the single chain plate.

[0008] Furthermore, the liquid removal mechanism includes: a square tube, fixedly installed at the middle position of the outer wall of the single chain plate; a support block, fixedly installed on the single chain plate inside the square tube; a support spring, fixedly connected to the top of the support block; a power block, fixedly connected to the top of the support spring, and its bottom end is slidably sealed inside the square tube, the square tube at the bottom of the power block being filled with insulating transmission fluid; two contact plates, including a horizontal plate and a vertical plate, respectively located on the side walls of the square tube facing both ends of the single chain plate, with one end of the horizontal plate inserted into the square tube, the horizontal plate of the contact plate slidingly contacting the single chain plate, and the horizontal plate inside the square tube being connected to the support block through an elastic tension strip; and a sponge, fixedly installed on the contact plate, and being a right-angled triangle.

[0009] Furthermore, scraping strips are fixedly installed on the side walls of the square tube facing both ends of the single chain plate. The width of the scraping strips is greater than the width of the contact plate, and the bottom end of the scraping strips is in close contact with the upper end surface of the horizontal plate of the contact plate.

[0010] Furthermore, the thickness of the square tube is less than the height of the lithium battery tab, and the thickness of the power block is less than the thickness of [other components].

[0011] Furthermore, the support spring is always in a compressed state.

[0012] Furthermore, two symmetrically arranged guide plates are fixedly connected to the side wall of the vertical baffle. The guide plates are located directly above the vertical plate of the contact plate, and the guide plates are inclined plates that gradually decrease in distance from the middle of the single chain plate.

[0013] Furthermore, a fixing mechanism for fixing the lithium battery is fixedly installed on both sides of the upright baffle. The fixing mechanism includes: a compression cylinder, fixedly installed on the side wall of the upright baffle near both ends; an elastic strip, fixedly installed on the upright baffle inside the compression cylinder; an inclined block, one end of which is slidably and sealed inside the compression cylinder; a fixing cylinder, fixedly installed in the middle position of the side wall of the upright baffle; and a fixing block, which is slidably and sealed inside the fixing cylinder. The fixing cylinder and the compression cylinder are connected by a connecting pipe. The compression cylinder at the bottom of the inclined block and the fixing cylinder at the bottom of the fixing block are filled with insulating transmission fluid.

[0014] Furthermore, a rubber disc is fixedly installed at the top of the fixing block.

[0015] This application has the following beneficial effects: 1. The present application provides a disassembly and conveying device for preventing voltage rebound during lithium battery discharge. When conveying a discharged lithium battery, the device makes the positive and negative terminals of the lithium battery conductive by contacting the two tabs of the lithium battery with the same single chain plate, forming an external short circuit. This keeps the voltage of the lithium battery from rebounding and prevents voltage rebound during the conveying of the discharged lithium battery, thereby avoiding fire, combustion, and explosion during subsequent cutting.

[0016] 2. The disassembly and conveying equipment for preventing voltage rebound during lithium battery discharge provided in this application involves placing the lithium battery on a single chain plate. During this process, the lithium battery squeezes the power block on the single chain plate. As the power block moves downward, it pushes the insulating fluid, which in turn pushes the contact plate to move towards both ends of the single chain plate. The contact plate drives the sponge to move synchronously. At this time, since the lithium battery tabs are in contact with the sponge, the moving sponge wipes the lithium battery tabs, removing the residual salt solution on the lithium battery tabs. This prevents the contact resistance from increasing due to residual salt solution on the lithium battery tabs, thus affecting the short-circuit effect of the lithium battery.

[0017] 3. The disassembly and conveying equipment for preventing voltage rebound during lithium battery discharge provided in this application involves the lithium battery squeezing the power block on the single chain plate. During the process of the contact plate being used at both ends of the single chain plate, the contact plate squeezes the inclined block on the upright baffle. The inclined block pushes the insulating transmission fluid in the squeezing cylinder, causing the insulating transmission fluid to enter the fixed cylinder through the connecting pipe. This causes the fixed block in the fixed cylinder to extend out and squeeze and fix the side wall of the lithium battery. When the transmission chain plate conveys the lithium battery, it prevents the lithium battery tabs from detaching from the contact plate due to vibration or uneven speed of the transmission chain plate, thus preventing the loss of short-circuit function.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0022] Example 1 Please see Figures 1-3A disassembly and conveying device for preventing voltage rebound during lithium battery discharge includes a support frame 1, side baffles 2, a chain plate drive wheel 3, a chain plate driven wheel 4, a geared motor 5, a transmission chain plate 6, and idlers 7. The support frame 1 is made of rectangular tubing of Q235 material. A base plate is fixedly installed on the top of the support frame 1. The support frame 1 is made of Q235 material. A side baffle 2 is fixedly connected to the edge of the top of the base plate. A chain plate drive wheel 3 is inserted into one end of the side baffle 2 and connected to the side baffle 2 by a bearing. A chain plate driven wheel 4 is inserted into the other end of the side baffle 2 and connected to the side baffle 2 by a bearing. The axes of the chain plate drive wheel 3 and the chain plate driven wheel 4 are parallel. A geared motor 5 is fixedly installed on one side of the outer wall of the side baffle 2. The output shaft of the geared motor 5 is connected to the chain plate. One end of the drive wheel 3 is fixedly connected to a reduction motor 5, which drives the drive wheel 3 to rotate. A transmission chain plate 6 is sleeved on the outside of the drive wheel 3 and the driven wheel 4. The transmission chain plate 6 is used to transport lithium batteries. The transmission chain plate 6 is ring-shaped and is made up of multiple single chain plates 61 that are hinged end to end in sequence. The width of a single chain plate 61 is 120mm and the length is 600mm. A chain is fixedly installed on the inner ring of the transmission chain plate 6. The chain on the inner ring of the transmission chain plate 6 meshes with the drive wheel 3 and the driven wheel 4. Multiple equidistant rollers 7 are inserted on the side baffle 2 between the drive wheel 3 and the driven wheel 4. The two ends of the rollers 7 are connected to the side baffle 2 through bearings, and the rollers 7 are used to support the transmission chain plate 6 above the drive wheel 3 and the driven wheel 4.

[0023] The bottom end of the bracket 1 is threaded with several adjustable feet 11. The adjustable feet 11 are used to adjust the contact point between the bracket 1 and the ground so that the bracket 1 can be placed horizontally on the ground. A galvanized flat iron is welded on the bracket 1. The galvanized flat iron is used for effective grounding.

[0024] A vertical baffle 8 is fixedly connected to one side of the top of the single chain plate 61. The plane of the vertical baffle 8 is perpendicular to the plane of the single chain plate 61. The distance between two adjacent vertical baffles 8 is the width of one single chain plate 61. The position between two vertical baffles 8 is a lithium battery storage station.

[0025] The geared motor 5 is electrically connected to a frequency converter, which is used to control the speed of the geared motor 5. The speed of the geared motor 5 can be adjusted by the frequency converter according to the production cycle, thereby adjusting the conveying speed of the transmission chain plate 6 to meet the production line needs of different production capacities.

[0026] The working principle of Embodiment 1 of the present invention is as follows: Please see Figures 1-3When using a conveying device to transport a discharged lithium battery, the lithium battery is placed on a single chain plate 61 between two vertical baffles 8, with the battery tabs facing downwards. This allows the two tabs of the lithium battery to contact the same single chain plate 61, thus making the positive and negative terminals of the lithium battery conductive and forming an external short circuit. This prevents the voltage of the lithium battery from rising back up, thus preventing the voltage from rising back up during the transport of the discharged lithium battery and avoiding fire, combustion, or explosion during subsequent cutting.

[0027] Example 2 Example 2 is a further improvement based on Example 1.

[0028] Unlike Example 1, please refer to Figures 1-8 A liquid removal mechanism 62 for wiping the lithium battery tabs is fixedly installed at the middle position of the outer wall of the single chain plate 61. The liquid removal mechanism 62 includes a square tube 621, a support block 622, a support spring 623, a power block 624, a contact plate 625, a sponge body 626, and an elastic tension strip 627. The square tube 621 is fixedly installed at the middle position of the outer wall of the single chain plate 61. The support block 622 is fixedly installed on the single chain plate 61 inside the square tube 621, and the support block 622 is located at the middle position of the single chain plate 61. The top of the support block 622 is fixedly connected to the support spring 623, which is located inside the square tube 621. The top of the support spring 623 is fixedly connected to the power block 624. The bottom end of the power block 624 is slidably sealed inside the square tube 621. The square tube 621 is filled with insulating transmission fluid. Contact plates 625 are inserted into the side walls of the square tube 621 facing both ends of the single chain plate 61. The contact plates 625 and the square tube 621 are slidably sealed at the insertion position. The contact plates 625 are made of Q235 material and are L-shaped. The contact plates 625 include a horizontal plate and a vertical plate. One end of the horizontal plate of the contact plate 625 is inserted into the square tube 621 and slides in contact with the single chain plate 61. The vertical plate of the contact plate 625 is fixedly connected to the other end of the horizontal plate. The horizontal plate inside the square tube 621 is connected to the support block 622 through an elastic tension strip 627. A sponge body 626 is fixedly installed on the side wall of the vertical plate of the contact plate 625 facing the middle of the single chain plate 61. The sponge body 626 is a right triangle and its two right-angled sides are respectively in close contact with the horizontal plate and the vertical plate of the contact plate 625.

[0029] Scraping strips 628 are fixedly installed on the side walls of the square tube 621 facing both ends of the single chain plate 61. The width of the scraping strips 628 is greater than the width of the contact plate 625, and the bottom end of the scraping strips 628 is close to the upper end surface of the horizontal plate of the contact plate 625. When the power block 624 is pressed down by the lithium battery, the power block 624 pushes the insulating transmission fluid in the square tube 621, thereby pushing the horizontal plate of the contact plate 625 to move outward of the square tube 621. After the pressure on the power block 624 is removed, the horizontal plate of the contact plate 625 is reset under the action of the elastic tension strip 627. At this time, the scraping strips 628 scrape the upper end surface of the horizontal plate of the contact plate 625 to prevent impurity particles from remaining on the horizontal plate of the contact plate 625, which would affect the subsequent contact between the lithium battery tab and the horizontal plate of the contact plate 625.

[0030] The thickness of the square tube 621 is less than the height of the lithium battery tab, and the thickness of the power block 624 is less than the thickness of 521. When the lithium battery squeezes the power block 624, the power block 624 can be inserted into the square tube 621 as a whole, and the lithium battery tab can contact the horizontal plate of the contact plate 625, preventing the lithium battery from being supported by the square tube 621, which would prevent the lithium battery tab from contacting the horizontal plate of the contact plate 625.

[0031] The support spring 623 is always in a compressed state. The compressed support spring 623 has a supporting elastic force. The support spring 623 supports the power block 624. When the power block 624 is not subjected to external force, the support spring 623 pushes the power block 624, causing the power block 624 to extend outward from the square tube 621.

[0032] Two symmetrically arranged guide plates 81 are fixedly connected to the side wall of the upright baffle 8. The guide plates 81 are located directly above the vertical plate of the contact plate 625. The guide plates 81 are inclined plates that gradually decrease in distance from the middle of the single chain plate 61. When the lithium battery is placed on the power block 624, the lithium battery is guided by the guide plates 81 on both sides to prevent the lithium battery from being placed inaccurately on the power block 624.

[0033] The two sides of the upright baffle 8 are fixedly installed with fixing mechanisms 9 for fixing lithium batteries. The fixing mechanism 9 includes a squeezing cylinder 91, an elastic strip 92, an inclined block 93, a fixing cylinder 95, a fixing block 96, and a connecting pipe 97. The squeezing cylinder 91 is fixedly installed on the side wall of the upright baffle 8 near both ends. The elastic strip 92 is fixedly installed on the upright baffle 8 inside the squeezing cylinder 91. The inclined block 93 is slidably and sealed inside the squeezing cylinder 91. The other end of the inclined block 93 extends out of the squeezing cylinder 91. The bottom end of the inclined block 93 is close to the elastic strip 92. The fixing cylinder 95 is fixedly installed in the middle of the side wall of the upright baffle 8. The fixing block 96 is slidably and sealed inside the fixing cylinder 95. The bottom end of the side wall of the fixing cylinder 95 is connected to the bottom end of the side wall of the squeezing cylinder 91 through the connecting pipe 97. The squeezing cylinder 91 at the bottom end of the inclined block 93 and the fixing cylinder 95 at the bottom end of the fixing block 96 are filled with insulating transmission fluid.

[0034] A rubber disc 98 is fixedly installed on the top of the fixing block 96. When the fixing block 96 is pushed out by the insulating transmission fluid and comes into contact with the side wall of the lithium battery, the rubber disc 98 at the top of the fixing block 96 is between the fixing block 96 and the side wall of the lithium battery, protecting the side wall of the lithium battery and preventing the fixing block 96 from being rigidly squeezed with the side wall of the lithium battery, which would cause the side wall of the lithium battery to break.

[0035] The working principle of Embodiment 2 of the present invention is as follows: Please see Figures 1-8 When conveying the discharged lithium battery using a conveying device, the lithium battery tabs are oriented towards the single chain plate 61, placing the lithium battery on the power block 624. The lithium battery's own weight and external pressure compress it downwards, causing the power block 624 to move towards the bottom of the square cylinder 621. The moving power block 624 compresses the insulating fluid at the bottom, causing the insulating fluid to compress the horizontal plates of the contact plates 625. This causes the horizontal plates of the contact plates 625 on both sides to move towards both ends of the single chain plate 61. The moving contact plates 625 drive the sponge 626 to move synchronously. Because the lithium battery is placed on the power block 624... When the power block 624 is in motion, the lithium battery tabs contact the sponge 626. As the contact plate 625 moves the sponge 626, the sponge 626 wipes away the residual salt solution on the lithium battery tabs, thus removing the residual salt solution. When the power block 624 is fully bent and moved into the square tube 621, the contact plate 625 and the sponge 626 move to their farthest positions, and the lithium battery tabs contact the horizontal plate of the contact plate 625, causing the lithium battery tabs to short-circuit through the horizontal plate of the contact plate 625. This prevents the contact resistance from increasing due to residual salt solution on the lithium battery tabs, which would affect the short-circuit effect of the lithium battery. When the contact plates 625 on both sides of the square tube 621 move towards the two ends of the single chain plate 61, the vertical plate of the contact plate 625 presses the inclined block 93 on the baffle 8, causing the inclined block 93 to slide into the extrusion cylinder 91. The moving inclined block 93 pushes the insulating transmission fluid in the extrusion cylinder 91, causing the insulating transmission fluid to enter the fixed cylinder 95 through the connecting pipe 97. This causes the insulating transmission fluid in the fixed cylinder 95 to push the fixed block 96, causing the fixed block 96 to move towards the side wall of the lithium battery. This causes the fixed block 96 to press and fix the side wall of the lithium battery. When the transmission chain plate 6 transports the lithium battery, it prevents the lithium battery from losing its short-circuit function due to vibration or uneven speed of the transmission chain plate 6.
