Technical Field

[0001] This utility model relates to the field of battery recycling technology, and in particular to a single-cell battery discharge device. Background Technology

[0002] In the context of carbon neutrality, the demand for recycling and reusing power batteries is gradually increasing. Power batteries contain heavy metals such as cobalt, nickel, and copper, as well as substances such as electrolytes, electrolytes, and organic solvents. If they are not treated in a timely manner, they will bring about some challenging environmental safety issues.

[0003] Currently, battery pack recycling technology in the industry is still in its early stages. The recycled power battery cells all carry varying degrees of charge, posing certain safety hazards. Therefore, it is necessary to discharge the power battery cells. However, in different power batteries, the positive and negative electrodes may be located on opposite sides of the cell or on the same side. As a result, a single discharge fixture is insufficient to discharge individual cells with different electrode distributions. Utility Model Content

[0004] The purpose of this utility model is to provide a single-cell battery discharge device to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0005] The technical solution adopted to solve the above-mentioned technical problems is as follows: A single-cell battery discharge device, comprising: a base plate; a top plate mounted on the base plate; a pressure plate slidably disposed on the base plate, and the pressure plate being located between the top plate and the base plate, wherein a positive electrode plate and a negative electrode plate are respectively mounted on both sides of the bottom of the pressure plate; a positive discharge clamp electrically connected to a positive wire, the positive wire being electrically connected to the positive electrode plate; and a negative discharge clamp electrically connected to a negative wire, the negative wire being electrically connected to the negative electrode plate.

[0006] This technical solution has at least the following beneficial effects: a single cell with positive and negative electrodes on the same side can be placed on the bottom plate, and the positive electrode plate and the negative electrode plate can be made to contact the corresponding electrode terminals of the single cell by sliding the pressure plate to realize the discharge process. For single cells with positive and negative electrodes on opposite sides, they can be placed on the top plate, and the positive electrode is held by a positive discharge clamp and the negative electrode is held by a negative discharge clamp to realize the discharge process. Therefore, it can adapt to the discharge treatment of single cells with different positive and negative electrode positions and improve adaptability.

[0007] As a further improvement to the above technical solution, a tray is placed on top of the base plate, and multiple flexible blocks are distributed on top of the tray. Individual battery cells are placed on top of the flexible blocks, which cushion the individual battery cells.

[0008] As a further improvement to the above technical solution, it also includes a frame and a first conveyor line for conveying the pallet, wherein the frame is equipped with a conveying mechanism for conveying the pallet from the first conveyor line to the base plate. Conveying the pallet to the corresponding base plate via the first conveyor line and the conveying mechanism facilitates manual loading.

[0009] As a further improvement to the above technical solution, the conveying mechanism includes a first telescopic cylinder mounted on the frame. The output end of the first telescopic cylinder is fitted with a slide plate slidably connected to the frame. The slide plate is fitted with a second telescopic cylinder whose telescopic direction is perpendicular to that of the first telescopic cylinder. The output end of the second telescopic cylinder is fitted with a pusher block for pushing the pallet. By driving the first and second telescopic cylinders to move the pusher block in two directional dimensions, the pallet can be pushed from the first conveyor line to the base plate.

[0010] As a further improvement to the above technical solution, limiting plates are provided on both sides of the base plate to restrict the position of the tray, and guide inclined plates are provided at both ends of the limiting plates. By guiding the tray to the position between the two limiting plates through the guide inclined plates, the position of the tray on the base plate is restricted, which can improve the accuracy of the tray placement and ensure the smooth discharge.

[0011] As a further improvement to the above technical solution, a screw is installed on the top of the pressure plate, and a drive shaft threadedly connected to the screw is rotatably installed on the top plate. By driving the drive shaft to rotate, the screw can be driven to move up and down, thereby driving the pressure plate to slide.

[0012] As a further improvement to the above technical solution, a frame is also included. The frame is equipped with a third telescopic cylinder, the output end of which is fitted with a drive motor. The output end of the drive motor is fitted with a splined shaft. The drive shaft has a splined hole, and the third telescopic cylinder can drive the splined shaft to insert into the splined hole. By driving the third telescopic cylinder to insert the splined shaft into the splined hole, the drive motor can drive the drive shaft to rotate, thereby driving the pressure plate to slide. When the third telescopic cylinder drives the splined shaft out of the splined hole, the base plate can be moved.

[0013] As a further improvement to the above technical solution, the top plate is equipped with heaters that are electrically connected to the positive electrode plate and the negative electrode plate, respectively. The individual battery cells are discharged by connecting the heaters.

[0014] As a further improvement to the above technical solution, a second conveyor line for conveying the base plate is also included. The second conveyor line is equipped with a fourth telescopic cylinder, the extension direction of which is perpendicular to the conveying direction of the second conveyor line. The output end of the fourth telescopic cylinder is equipped with a stop for restricting the conveying of the base plate. By driving the fourth telescopic cylinder to move the stop to block the conveying of the base plate, the base plate is restricted at the workstation, so that the individual battery cells can be placed on the base plate.

[0015] As a further improvement to the above technical solution, the second conveyor line is equipped with a fifth telescopic cylinder whose telescopic direction is perpendicular to that of the fourth telescopic cylinder. The telescopic direction of the fifth telescopic cylinder is perpendicular to the conveying direction of the second conveyor line. A positioning block for pressing the base plate against the side wall of the second conveyor line is installed at the output end of the fifth telescopic cylinder. By driving the fifth telescopic cylinder to move the positioning block and the second conveyor line together to clamp the base plate, the stability of the base plate during positioning can be improved.

[0026] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0027] Reference Figure 1-5 The single-cell battery discharge device includes a base plate 100, a frame 200, a first conveyor line 300, and a second conveyor line 600.

[0028] Multiple guide posts are provided at the top edge of the base plate 100, and the top of the multiple guide posts are fixed together to the top plate 110, with a certain height space between the top plate 110 and the base plate 100. The multiple guide posts are slidably connected to the pressure plate 120, that is, the pressure plate 120 is located between the top plate 110 and the base plate 100.

[0029] A positive electrode plate 121 and a negative electrode plate 122 are respectively installed on both sides of the bottom of the pressure plate 120. A positive wire 141 and a negative wire 142 are respectively passed through the pressure plate 120. One end of the positive wire 141 passes through the bottom of the pressure plate 120 and is electrically connected to the positive electrode plate 121, and the other end passes through the top of the pressure plate 120 and is connected to the positive discharge clamp 131. One end of the negative wire 142 passes through the bottom of the pressure plate 120 and is electrically connected to the negative electrode plate 122, and the other end passes through the top of the pressure plate 120 and is connected to the negative discharge clamp 132.

[0030] Understandably, the positive electrode plate 121 and the negative electrode plate 122 are used for battery discharge. When a single cell with its positive and negative terminals on the same side is placed on top of the base plate 100, the pressure plate 120 moves downwards, causing the positive electrode plate 121 to contact the positive terminal of the single cell and the negative electrode plate 122 to contact the negative terminal of the single cell, thus allowing the single cell to discharge through the positive electrode plate 121 and the negative electrode plate 122.

[0031] When it is necessary to discharge a single cell with the positive and negative terminals located on different sides, the single cell can be placed on the top plate 110 or the bottom plate 100. Then, the positive discharge clamp 131 is clamped on the positive terminal of the single cell, and the negative discharge clamp 132 is clamped on the negative terminal of the single cell. This allows the single cell to be electrically connected to the positive electrode plate 121 and the negative electrode plate 122 through the clamping of the positive discharge clamp 131 and the negative discharge clamp 132, thereby realizing the discharge process.

[0032] A tray 151 is placed on top of the base plate 100. The top of the tray 151 has a receiving groove, and the bottom of the receiving groove has multiple flexible blocks 152, each made of silicone granules. These silicone granules are arranged in a matrix and fixed to the pad, forming a silicone granule pad. When a single battery cell is placed in the receiving groove, the flexible blocks 152 cushion the battery, preventing the pressure plate 120 from damaging it. A certain gap exists between adjacent flexible blocks 152, which promotes heat dissipation during discharge, ensuring smooth discharge.

[0033] A screw 420 is mounted in the center of the top of the pressure plate 120, and a drive shaft 421 is rotatably mounted in the center of the top of the top plate 110. The drive shaft 421 is vertically arranged, and its bottom end passes through the top plate 110 and is threadedly connected to the top end of the screw 420. By rotating the drive shaft 421, the screw 420 can be driven to move up and down, thereby causing the pressure plate 120 to slide up and down, adjusting the pressure plate 120 so that the positive electrode plate 121 and the negative electrode plate 122 just press against the corresponding positive and negative terminals of the single cell.

[0034] The conveying directions of the first conveyor line 300 and the second conveyor line 600 are perpendicular to each other. The first conveyor line 300 includes a third conveyor line 310 and a fourth conveyor line 320 spliced ​​together. The third conveyor line 310 and the fourth conveyor line 320 have the same conveying direction. Both the third conveyor line 310 and the second conveyor line 600 are roller conveyors. The fourth conveyor line 320 has conveying rollers arranged side by side on both sides along the conveying direction. The conveying end of the third conveyor line 310 is connected to the conveying front end of the fourth conveyor line 320, and the conveying end of the fourth conveyor line 320 is located on one side of the second conveyor line 600. The fourth conveyor line 320 is equipped with a conveying mechanism. The base plate 100 is placed on the second conveyor line 600, and the base plate 100 and the individual cells undergoing discharge processing can be conveyed through the second conveyor line 600.

[0035] Workers place individual cells on tray 151 in a specific orientation and then place tray 151 on the third conveyor line 310. The third conveyor line 310 transports tray 151 to the fourth conveyor line 320, which in turn transports tray 151 to a position close to the second conveyor line 600. A conveying mechanism then transports tray 151 to the top surface of the base plate 100 on the second conveyor line 600. This allows the positive electrode plate 121 and negative electrode plate 122 on the pressure plate 120 to discharge the individual cells on tray 151.

[0036] An extension plate is installed on the top plate 110, and a resistance conduit heater 710 is installed at the bottom of the extension plate. The positive and negative terminals of the heater 710 are electrically connected to the positive electrode plate 121 and the negative electrode plate 122, respectively. Discharge can be performed through the heater 710. During discharge, the heater 710 is placed in a cooling water tank for heat dissipation, thereby improving the discharge efficiency.

[0037] The conveying mechanism includes a first telescopic cylinder 410, a slide plate 401, and a second telescopic cylinder 430. The telescopic direction of the first telescopic cylinder 410 is the same as the conveying direction of the fourth conveyor line 320. The frame 200 is fixedly connected to the frame of the fourth conveyor line 320. The slide plate 401 is slidably disposed at the top of the frame 200, allowing the slide plate 401 to slide relative to the fourth conveyor line 320. The slide plate 401 is mounted on the output end of the first telescopic cylinder 410, enabling the first telescopic cylinder 410 to drive the slide plate 401 to slide horizontally and stably. The second telescopic cylinder 430 is mounted on the slide plate 401, and its output end is vertically downward and equipped with a pusher block 440.

[0038] By driving the first telescopic cylinder 410 and the second telescopic cylinder 430, the pusher 440 can be lowered to the same height as the pallet 151, and the pallet 151 can be moved from the fourth conveyor line 320 to the base plate 100 of the second conveyor line 600.

[0039] The base plate 100 has limit plates 101 installed on both sides. The distance between the two limit plates 101 is just enough to accommodate a pallet 151, or the distance between the two limit plates 101 is slightly greater than the width of the pallet 151, so that the pallet 151 can be positioned between the two limit plates 101. Guide inclined plates 102 are provided at both ends of the two limit plates 101, and the guide inclined plates 102 are integrally formed with the corresponding limit plates 101. When the pallet 151 enters the base plate 100, the guide inclined plates 102 guide the pallet 151, allowing it to smoothly enter between the two limit plates 101.

[0040] A third telescopic cylinder 500 is mounted on the top of the frame 200. The output end of the third telescopic cylinder 500 is downward-facing and equipped with a sliding guide plate 501, which is vertically slidably positioned on one side of the frame 200. A drive motor 510 is mounted on the sliding guide plate 501. The output end of the drive motor 510 is downward-facing and equipped with a splined shaft 520. A splined hole 422 is formed on the top surface of the drive shaft 421, and the shape of the splined hole 422 is adapted to the shape of the splined shaft 520.

[0041] When the third telescopic cylinder 500 drives the drive motor 510 and splined shaft 520 to move downwards, the splined shaft 520 is inserted into the splined hole 422. The drive motor 510 can then drive the transmission shaft 421 to rotate via the splined shaft 520, causing the slide plate 401 to move up and down to adjust to the position of the single battery to be discharged. When the third telescopic cylinder 500 drives the drive motor 510 and splined shaft 520 to move upwards, the splined shaft 520 can extend out of the splined hole 422, thus not obstructing the conveying of the base plate 100. It is understood that the cross-sectional shape of the splined shaft 520 is a non-circular structure such as a triangle, quadrilateral, or pentagon. In other embodiments, a sleeve can also be provided at the output end of the drive motor 510, with a splined hole 422 on the bottom surface of the sleeve, and the splined shaft 520 can be mounted on the top of the transmission shaft 421.

[0042] In addition, a detector is provided on the sliding guide plate 501, and the top plate 110 is equipped with detection points that are electrically connected to the positive electrode plate 121 and the negative electrode plate 122, respectively. When the third telescopic cylinder 500 drives the sliding guide plate 501 to move downward, it also drives the detector to contact the detection points, thereby detecting the charge of the individual battery cells to facilitate the control of the discharge process.

[0043] The second conveyor line 600 is equipped with a fourth telescopic cylinder 810, which is located below the conveying path of the base plate 100. The output end of the fourth telescopic cylinder 810 faces upward and is equipped with a stop block 811. The telescopic direction of the fourth telescopic cylinder 810 is perpendicular to the conveying direction of the second conveyor line 600. A protrusion is provided on the side of the stop block 811 facing the front end of the second conveyor line 600, and the protrusion and stop block 811 are integrally formed. A groove adapted to be inserted into is opened on the side of the base plate 100 facing the end of the second conveyor line 600. By driving the fourth telescopic cylinder 810, the stop block 811 is raised to the conveying path of the base plate 100, so that the stop block 811 can block the continued conveying of the base plate 100 and stop the base plate 100 at a preset working position, so as to push the pallet 151 onto the base plate 100.

[0044] An arc-shaped guide plate 610 is installed on the side of the second conveyor line 600 away from the fourth conveyor line 320. When the bottom plate 100 conveyed on the second conveyor line 600 passes the arc-shaped guide plate 610, it can move closer to the fourth conveyor line 320 under the guidance of the arc surface of the arc-shaped guide plate 610, so that the pallet 151 can be pushed onto the bottom plate 100.

[0045] The second conveyor line 600 is equipped with a fifth telescopic cylinder 910. The telescopic direction of the fifth telescopic cylinder 910 is not only perpendicular to the telescopic direction of the fourth telescopic cylinder 810, but also perpendicular to the conveying direction of the second conveyor line 600.

[0046] The fifth telescopic cylinder 910 is also located below the conveying path of the base plate 100. A positioning block 911 is installed at the output end of the fifth telescopic cylinder 910. A notch for accommodating the positioning block 911 is opened on one side of the arc-shaped guide plate 610. When the base plate 100 passes the arc-shaped guide plate 610, it moves closer to the fourth conveying line 320 under the guidance of the arc-shaped guide plate 610. The fifth telescopic cylinder 910 is then driven to move the positioning block 911 closer to the fourth conveying line 320 until the positioning block 911 clamps the base plate 100 with the side wall of the second conveying line 600. This stabilizes the position of the base plate 100 and further facilitates pushing the pallet 151 onto the base plate 100.

[0047] It should be noted that a tray 151 can be provided with two receiving slots to allow two single cells to be discharged simultaneously. Correspondingly, two positive electrode plates 121, two negative electrode plates 122, two positive wires 141, two negative wires 142, two positive discharge clamps 131 and two negative discharge clamps 132 are installed on the pressure plate 120. The two sets of discharge electrode plate structures are electrically connected to the same heater 710 to achieve discharge.

[0048] This application uses a resistance heater 710 for connection discharge. Individual cells can be completely discharged within 2 hours, improving the discharge efficiency of traditional discharge cabinet methods. Furthermore, this application can discharge not only cells with the same positive and negative terminals on one side, but also cells with terminals on opposite sides. It also reduces the labor intensity of manual operation, requiring only loading and unloading, and ensuring the safety of manual operation. The specific implementation steps are as follows:

[0049] Step 1: First, place the individual battery cells that need to be discharged in the loading area using a forklift;

[0050] Step 2: Fill the circulating water tank for cooling heater 710 with cooling water to a suitable level, connect the production line to the power supply and turn on the power switch to complete the preparation work.

[0051] Step 3: Set the thickness, width, height and center distance of the individual cells, load them onto the conveyor belt, and transport the cells to the welding machine for welding the positive and negative electrode tabs.

[0052] Step 4: After welding is completed, the mechanical grippers place the batteries into tray 151 in the order of positive and negative terminals.

[0053] Step 5: The pallet 151 moves along the third conveyor line 310 and the fourth conveyor line 320 to a position close to the second conveyor line 600, and is pushed onto the positioned base plate 100 by the conveying mechanism. The drive screw 420 is pressed down to move the slide plate 401 to the set position.

[0054] Step 6: The tray 151 can be transported via the second conveyor line 600, and the discharge is completed after running one revolution along the circulating water pool;

[0055] Step 7: After reaching the designated position, drive screw 420 to rise, which in turn drives slide plate 401 to rise, and then push out tray 151 to remove the discharged individual battery. The unloading is then complete.

[0056] The above steps are simple to operate and can basically realize automatic discharge of various types of single batteries. This device and its usage do not require high skill levels from personnel; personnel only need to load and unload materials.

[0057] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
