Description

Technical Field

[0001] This invention relates to the field of battery disassembly technology, and in particular to a cell unpacking device and battery disassembly equipment. Background Technology

[0002] With increasing societal focus on environmental protection, new energy vehicles are becoming increasingly prevalent in people's daily lives. As a crucial component of new energy vehicles, power batteries need to be disassembled and replaced after reaching a certain level of degradation. To reduce the impact of end-of-life batteries on the ecosystem and the environment, they are often disassembled and recycled. Simultaneously, some waste power batteries often require disassembly and inspection to identify manufacturing process defects and improve the success rate of power battery production.

[0003] The current mainstream method for disassembling batteries involves manually cutting open individual cells to remove the bare cells, detaching them from the casing, and then manually cutting the binding adhesive to restore the cells to their individual cell pack state. However, this manual process not only results in low efficiency but also poses a risk of electrolyte contact with the human body, posing a health hazard. Summary of the Invention

[0004] Therefore, it is necessary to address the problem that manual battery decoating not only results in low decoating efficiency but also poses significant health risks. A solution should be provided that can improve the efficiency of battery decoating and reduce the harm to the human body.

[0005] A battery cell unpacking device, comprising:

[0006] Positioning fixture, used to clamp and position the battery;

[0007] The positioning fixture is mounted on the conveying mechanism, and the conveying mechanism is used to drive the positioning fixture to move sequentially between the battery loading station, the top cover cutting station, the electrolyte pouring station, the bottom cover cutting station, the cell unpacking station and the outer shell rejection station.

[0008] The top cover cutting station, bottom cover cutting station, cell unpacking station, and outer shell rejection station are sequentially equipped with a top cover cutting mechanism, a bottom cover cutting mechanism, an ejection mechanism, and a rejection mechanism. The top cover cutting station is used to cut the top cover of the battery. The positioning fixture can drive the battery to rotate relative to the conveying mechanism to pour out the electrolyte. The bottom cover cutting mechanism is used to cut the bottom cover of the battery after the electrolyte has been poured out to form a through hole. The ejection mechanism passes through the through hole into the outer shell to eject the cell out of the outer shell. The rejection mechanism removes the outer shell from the positioning fixture.

[0009] In one embodiment, the conveying mechanism includes a turntable that can rotate about a first axis to drive the positioning fixture to move between workstations.

[0010] In one embodiment, there are 6 positioning fixtures, and the interval between each two adjacent positioning fixtures on the turntable is 60°.

[0011] The interval angle between any two adjacent stations in the battery loading station, the top cover cutting station, the electrolyte pouring station, the bottom cover cutting station, the cell unpacking station, and the outer casing removal station is 60°.

[0012] In one embodiment, the cell unpacking device includes multiple support mechanisms, each of which includes a support column, a universal bearing, and an adjusting screw.

[0017] The clamping assembly is used to clamp or release the battery supported on the tray. When the tray rotates about the second axis relative to the bracket, it can switch the battery between a horizontal state and an inclined state. The baffle is used to prevent the battery from sliding off the tray when the battery is in the inclined state.

[0018] In one embodiment, the positioning fixture further includes a top block and a first follower block. The first follower block is connected to the pallet. The top block is movably mounted on the bracket along a straight line. When the top block moves relative to the bracket, the first follower block moves with the top block to drive the pallet to rotate around the second axis; and / or

[0019] The baffle is rotatably mounted on the bracket around a third axis so as to switch between a blocking state that blocks the battery and a releasing state that releases the battery; the positioning fixture also includes a top block and a second follower block. The top block is movably mounted on the bracket. When the top block moves relative to the bracket, the second follower block moves with the top block and abuts against the baffle, so that the baffle switches from the releasing state to the blocking state.

[0020] In one embodiment, the positioning fixture further includes an elastic element for switching the baffle from the blocking state to the releasing state.

[0021] In one embodiment, the battery loading station is provided with a pushing mechanism and a first blocking mechanism;

[0027] The positioning fixture has a limiting block. The actuating mechanism can move the battery to the bottom cover and abut against the limiting block. The bottom cover cutting mechanism is used to cut the bottom cover that abuts against the limiting block. The actuating mechanism can also move the battery to one end of the top cover and abut against the second blocking mechanism. The second blocking mechanism is used to limit the battery.

[0028] In one embodiment, the actuation mechanism includes a pawl drive assembly and a pawl connected to each other, the pawl drive assembly being used to drive the pawl to move and actuate the battery.

[0029] and / or

[0030] The second blocking mechanism includes a second stop block and a second stop block drive assembly connected to each other. The second stop block drive assembly is used to drive the second stop block to move in order to block the limiting battery.

[0031] In one embodiment, the top cover cutting mechanism includes a saw blade lifting assembly and a saw blade assembly connected to each other. The saw blade lifting assembly is used to drive the saw blade assembly to lift and lower, and the saw blade of the saw blade assembly is capable of rotating to cut the top cover of the battery.

[0032] and / or

[0033] The bottom cover cutting mechanism includes a milling cutter feed assembly and a milling cutter assembly connected to each other. The milling cutter feed assembly is used to drive the milling cutter assembly to move and cut the battery casing.

[0034] In one embodiment, the ejection mechanism includes a push rod and at least one stage of push rod translation assembly, the push rod translation assembly being used to drive the push rod to move and eject the battery cell from the housing;

[0035] and / or

[0036] The rejection mechanism includes a second push plate and a second push plate drive assembly connected to each other. The second push plate drive assembly is used to drive the second push plate to move and push the outer shell.

[0038] The aforementioned cell removal device and battery disassembly equipment, with positioning fixtures sequentially moving between the battery loading station, top cover cutting station, electrolyte pouring station, bottom cover cutting station, cell removal station, and outer casing rejection station, performs the following processes in sequence: battery loading, top cover cutting, electrolyte pouring, bottom cover cutting, cell removal, and outer casing rejection. This ensures that the cell can be removed from the individual battery casing. Compared to the existing technology that manually removes the cell from the casing, this method not only has higher removal efficiency but also prevents the electrolyte from coming into contact with the human body during cell removal, thus solving the problem of electrolyte hazard to human health.

[0062] See Figures 1-3 This application provides a battery cell unpacking device 100 for removing battery cells from the casing of a single battery cell 200. The battery cell unpacking device 100 includes a positioning fixture 10 and a conveying mechanism 20, with the positioning fixture 10 mounted on the conveying mechanism 20. The conveying mechanism 20 drives the positioning fixture 10 to sequentially move between battery loading station A, top cover cutting station B, electrolyte pouring station C, bottom cover cutting station D, battery cell unpacking station E, and casing rejection station F. When the positioning fixture 10 is at battery loading station A, the battery 200 is loaded onto the positioning fixture 10, which clamps and positions the battery 200. The battery 200 then moves synchronously with the positioning fixture 10 to the subsequent station.

[0063] Continue reading Figure 1 The battery 200 unpacking device also includes a top cover cutting mechanism 30, a bottom cover cutting mechanism 40, an ejection mechanism 50, and a rejection mechanism 60. The top cover cutting mechanism 30 is set at the top cover cutting station B, the bottom cover cutting mechanism 40 is set at the bottom cover cutting station D, the ejection mechanism 50 is set at the cell unpacking station E, and the rejection mechanism 60 is set at the outer shell rejection station F. When the battery 200 flows to the top cover cutting station B with the positioning fixture 10, the top cover cutting mechanism 30 cuts off the top cover 201 of the battery 200 outer shell. When the battery 200 flows to the electrolyte pouring station C with the positioning fixture 10, the positioning fixture 10 can drive the battery 200 to rotate relative to the conveying mechanism 20 to pour the electrolyte. When the battery 200 flows to the bottom cover cutting station D with the positioning fixture 10, the bottom cover cutting mechanism 40 is used to cut the bottom cover 202 of the battery 200 after the electrolyte has been poured out, so that a through hole is formed on the bottom cover 202. When battery 200 flows with positioning fixture 10 to cell unpacking station E, ejection mechanism 50 can pass through the through hole into the outer casing to eject the cell out of the casing. When battery 200 flows with positioning fixture 10 to casing rejection station F, rejection mechanism 60 is used to remove the casing from positioning fixture 10. Positioning fixture 10 returns to battery loading station A, and the next battery 200 is loaded onto positioning fixture 10, where cell unpacking device 100 performs unpacking processing on the next battery 200.

[0064] It should be noted that the top cover 201 and bottom cover 202 of the battery 200 are arranged opposite each other. When the top cover 201 is cut off and a through hole is opened on the bottom cover 202, the ejection mechanism 50 can pass through the through hole into the outer casing and eject the battery cell from the end of the outer casing where the top cover 201 has been cut off. In some specific embodiments, the ejection mechanism 50 can eject the entire battery cell out of the outer casing, that is, the ejection mechanism 50 can eject the battery cell out of the outer casing without the need for other structural assistance. In other specific embodiments, the ejection mechanism 50 can eject a portion of the battery cell out of the outer casing, and an external structure clamps the portion of the battery cell that has been ejected from the outer casing and pulls the battery cell out of the outer casing. In this case, the ejection mechanism 50 cooperates with the external structure to separate the battery cell from the outer casing.

[0065] The battery cell unpacking device 100 provided in this embodiment of the application uses a positioning fixture 10 that sequentially moves between battery loading station A, top cover cutting station B, electrolyte pouring station C, bottom cover cutting station D, battery cell unpacking station E, and outer casing rejection station F. This sequentially performs the processes of battery 200 loading, top cover 201 cutting, electrolyte pouring, bottom cover 202 cutting, battery cell unpacking, and outer casing rejection, ensuring that the battery cell can be removed from the outer casing of the individual battery 200. Compared to the existing technology that uses manual operation to detach the battery cell from the outer casing, this method not only has higher unpacking efficiency but also prevents the electrolyte from coming into contact with the human body during unpacking, thus solving the problem of electrolyte hazard to human health.

[0066] In some embodiments, the battery cell unpacking device 100 further includes a control mechanism, and the conveying mechanism 20, positioning fixture 10, top cover cutting mechanism 30, bottom cover cutting mechanism 40, ejection mechanism 50, and rejection mechanism 60 are all connected to the control mechanism. The control mechanism controls the coordinated operation of the above-mentioned mechanisms.

[0067] In some embodiments, see further reference. Figure 2 The conveying mechanism 20 includes a turntable 21, which can rotate around a first axis to drive the positioning fixture 10 to move between various workstations. Optionally, the turntable 21 can be a round disc, a square disc, or other irregularly shaped disc. The conveying mechanism 20 is configured such that the rotation of the turntable 21 drives the positioning fixture 10 to move between various workstations. Compared with the method of using a conveyor belt to drive the positioning mechanism 90 to move between various workstations, the footprint of the conveying mechanism 20 can be reduced, thereby reducing the footprint of the entire battery cell decasing device 100.

[0068] It should be understood that in some other embodiments, the conveying mechanism 20 may also include a conveyor belt, which is circular, and the movement of the conveyor belt drives the positioning fixture 10 on it to move between various workstations. Of course, in other embodiments, the specific arrangement of the conveying mechanism 20 is not limited, as long as it can achieve the effect of driving the positioning fixture 10 to move between various workstations.

[0069] Further reading Figure 2 There are six positioning fixtures 10, with each pair of adjacent fixtures 10 spaced 60° apart on the turntable 21. The battery loading station A, top cover cutting station B, electrolyte pouring station C, bottom cover cutting station D, cell removal station E, and outer casing removal station F are arranged sequentially along the rotation direction of the turntable 21, with each pair of adjacent stations spaced 60° apart. This arrangement ensures that when any one positioning fixture 10 moves to a station, the other positioning fixtures 10 correspond to the remaining stations, allowing all six stations to operate simultaneously. This means that the cell removal process for six batteries 200 can be performed concurrently, improving the efficiency of cell removal.

[0070] It should be understood that in some other embodiments, the number of positioning fixtures 10 and the spacing angle between each positioning fixture 10 on the turntable 21 are not limited. For example, in some specific embodiments, there can be 1, 2, 3, 4, 5 or more than 6 positioning fixtures 10. And when there are multiple positioning fixtures 10, the spacing angle between each positioning fixture 10 can be greater than 60° or less than 60°. Furthermore, when each station is arranged along the circumference of the turntable 21, the spacing angle between each station is not limited. For example, the spacing angle between some adjacent stations can be greater than 60°, and the spacing angle between other adjacent stations can be less than 60°.

[0071] Continue reading Figure 3 The battery cell decasing device 100 also includes a drive mechanism 70. The conveying mechanism 20 is connected to the drive mechanism 70, and the drive mechanism 70 is used to move the conveying mechanism 20 to improve the automation level of the battery cell decasing device 100. The drive mechanism 70 can be driven by a motor or a cylinder.

[0072] The cell decasing device 100 also includes a frame (not shown in the figure). The drive mechanism 70, top cover cutting mechanism 30, bottom cover cutting mechanism 40, ejection mechanism 50, and rejection mechanism 60 are all mounted on the frame to improve the integration of the cell decasing device 100. The turntable 21 is connected to the drive end of the drive mechanism 70, and the turntable 21 rotates relative to the frame around a first axis. In some other embodiments, the cell decasing device 100 may omit the frame, in which case the various structures are distributed separately.

[0073] In some embodiments, see further reference. Figure 2 and Figure 3 The cell decasing device 100 also includes multiple support mechanisms 80 mounted on a frame. (See also...) Figure 4Each support mechanism 80 includes a support column 81, a universal bearing 82, and an adjusting screw. The universal bearing 82 and the adjusting screw are respectively located at the top and bottom of the support column 81. The universal bearing 82 abuts against the turntable 21, supporting the turntable 21 away from its center of rotation. The adjusting screw is used to adjust the height of the support column 81. By adjusting the height of the support column 81, the adjusting screw ensures that all universal bearings 82 are on the same horizontal plane. Since the universal bearings 82 abut against the lower surface of the turntable 21, when multiple universal bearings 82 are on the same horizontal plane, the turntable 21 can also be horizontal, reducing the tilt of the turntable 21 and the positioning fixture 10 relative to the horizontal plane, and ensuring the cutting effect of the top cover 201 and bottom cover 202 of the cutting shell. At the same time, the universal bearings 82 and the turntable 21 have rolling friction, which reduces friction and minimizes the impact on the rotation of the turntable 21.

[0074] In some specific embodiments, there are six support mechanisms 80, which are arranged sequentially and at intervals along the rotation direction of the turntable 21. Specifically, the interval angle between any two adjacent support mechanisms 80 is 60°. In this way, when the six positioning fixtures 10 are operating at the six workstations respectively, the six support mechanisms 80 precisely support the positions of the six positioning fixtures 10 on the turntable 21, thereby achieving a better support effect.

[0075] Of course, in other embodiments, the number of support mechanisms 80 is not limited, nor is the position of the support mechanism 80 supporting the turntable 21. For example, the number of support mechanisms 80 can be 1, 2, 3, 4, 5 or more than 6, and the angle between two adjacent support mechanisms 80 can be greater than 60° or less than 60°.

[0076] In some embodiments, see further reference. Figure 3 The battery cell decasing device 100 also includes a positioning mechanism 90 mounted on a frame. The conveying mechanism 20 has multiple mating parts 110 corresponding to multiple workstations. These mating parts 110 cooperate with the positioning mechanism 90 to position the positioning fixture 10 at the corresponding workstation. Specifically, the battery cell decasing device 100 has six mating parts 110, which cooperate with the positioning mechanism 90 to position the positioning fixture 10 at the aforementioned six workstations. Through the coordinated positioning of the positioning mechanism 90 and the mating parts 110, it is ensured that the positioning mechanism 90 is accurately positioned at each workstation, guaranteeing the effective decasing of the battery cells.

[0077] Optionally, see Figure 5The positioning mechanism 90 includes a detection element 91, a positioning drive assembly 92, and a positioning block 93. The positioning block 93 is connected to the positioning drive assembly 92. The detection element 91 is used to detect whether the conveying mechanism 20 has moved into position. When the detection element 91 detects that the conveying mechanism 20 has moved into position, the control mechanism controls the positioning drive assembly 92 to move. The positioning drive assembly 92 drives the positioning block 93 to move, and the positioning block 93 cooperates with the mating part 110 to position the conveying mechanism 20. The positioning drive assembly 92 can use a motor as the drive element to drive the positioning block 93 to move.

[0078] In some embodiments, the detection element 91 is a sensor, which has a transmitting end and a receiving end. When the mating part 110 on the conveying mechanism 20 moves to block the signal transmission between the transmitting end and the receiving end, it proves that the conveying mechanism 20 has moved into position. Of course, in other embodiments, the type of detection element 91 is not limited, as long as it has the function of detecting whether the conveying mechanism 20 is in position.

[0079] Optionally, please continue reading Figure 5 The positioning block 93 is provided with a groove 931, and the mating part 110 is a positioning post. The positioning post can be accommodated in the groove 931 of the positioning block 93, restricting the conveying mechanism 20 from continuing to move and positioning the conveying mechanism 20 to a preset position.

[0080] In other embodiments, the engagement method of the positioning block 93 and the mating part 110 is not limited. For example, the positioning block 93 and the mating part 110 may be provided with a snap-fit ​​part, and the two snap-fit ​​parts may engage with the positioning and conveying mechanism 20.

[0081] In some embodiments, see Figure 6 and Figure 7 The positioning fixture 10 includes a bracket 11, a tray 12, and a clamping assembly 13. The bracket 11 is mounted on the conveying mechanism 20, the tray 12 is mounted on the bracket 11, and the clamping assembly 13 is connected to the tray 12. The battery 200 is conveyed to the tray 12, and the clamping assembly 13 clamps or releases the battery 200 supported on the tray 12.

[0082] Optionally, the clamping assembly 13 includes two clamping blocks 131, which can close or open to clamp or release the battery 200. When the two clamping blocks 131 are closed, they can clamp the battery 200 from both ends respectively, with the clamping blocks 131 clamping the battery 200 away from the top cover 201 and the bottom cover 202. Generally, if the line connecting the top cover 201 and the bottom cover 202 is along the length of the battery 200, then the two clamping blocks 131 clamp the battery 200 from both ends along the width or thickness direction of the battery 200, preventing the clamping blocks 131 from contacting the top cover 201 or the bottom cover 202 and affecting the cutting of the top cover 201 or the bottom cover 202.

[0083] See Figure 8 The positioning fixture 10 also includes an opening and closing drive assembly 14, which is connected to the support plate 12. Two clamping blocks 131 are connected to the opening and closing drive assembly 14. The opening and closing drive assembly 14 drives the two clamping blocks 131 to move, causing the two clamping blocks 131 to open or close. In some specific embodiments, the opening and closing drive assembly 14 includes a gear 141 and a rack 142. Both racks 142 mesh with the gear 141, and the two clamping blocks 131 are respectively connected to the two racks 142. When the gear 141 rotates, it drives the two racks 142 to move, causing the two clamping blocks 131 to move in tandem, thereby opening or closing the two clamping blocks 131. Optionally, the opening and closing drive assembly 14 also includes an opening and closing drive element, which drives the gear 141 to rotate. In other specific embodiments, the opening and closing drive assembly 14 can also be set in other ways, as long as it can achieve the purpose of driving the clamping blocks 131 to open or close. For example, the opening and closing drive assembly 14 can also be set to include a screw and a nut, the two ends of the screw have opposite helical directions, the two nuts are screwed to the two ends of the screw respectively, the two clamping blocks 131 are connected to the two nuts respectively, and the rotation of the screw drives the two nuts to move, so that the two clamping blocks 131 open or close.

[0084] In some embodiments, see further reference. Figure 1 The cell unpacking device 100 also includes a pushing mechanism 120 and a first blocking mechanism 130 mounted on a frame, which are positioned corresponding to the battery loading station A. When the batteries 200 are loaded onto the positioning fixture 10, the positions of each battery 200 on the positioning fixture 10 may deviate. The pushing mechanism 120 can push one end of the battery 200 with the bottom cover 202, causing one end of the battery 200 with the top cover 201 to abut against the first blocking mechanism 130. The pushing mechanism 120 and the first blocking mechanism 130 cooperate to perform secondary positioning of the batteries 200, ensuring that the positions of the batteries 200 on the positioning fixture 10 are consistent, thereby facilitating the subsequent cutting of the top cover 201 of the battery 200.

[0085] Optionally, see Figure 9 The actuating mechanism 120 includes a first push plate 121 and a first push plate drive assembly 122 connected to each other. The first push plate drive assembly 122 is used to drive the first push plate 121 to move and push the battery 200. See also Figure 10The first blocking mechanism 130 includes a first stop 1301 and a first stop driving assembly 132 connected to each other. The first stop driving assembly 132 is used to drive the first stop 1301 to move in order to block and position the battery 200. Thus, when positioning the battery 200, the first stop driving assembly 132 drives the first stop 1301 to move to a preset position, and the first push plate driving assembly 122 drives the first push plate 121 to move. The first push plate 121 pushes one end of the battery 200 with the bottom cover 202 until the top cover 201 of the battery 200 contacts the first stop 1301, thereby completing the positioning of the battery 200.

[0086] Further reading Figure 11 and Figure 12 The positioning fixture 10 also includes a baffle 15. A support plate 12 is rotatably mounted on a bracket 11 about a second axis. A clamping assembly 13 is connected to the support plate 12 and can rotate with the support plate 12 relative to the bracket 11. The baffle 15 is connected to the bracket 11. When the support plate 12 rotates about the second axis relative to the bracket 11, it allows the battery 200 to be in a horizontal position (see...). Figure 11 ) and tilt state (see Figure 12 The baffle 15 is used to prevent the battery 200 from sliding off the tray 12 when the battery 200 is in an inclined state. With this configuration, the battery 200 is placed on the tray 12, and the clamping assembly 13 clamps the battery 200. When the positioning fixture 10 is conveyed to the electrolyte pouring station C by the conveying mechanism 20, the tray 12 drives the battery 200 to switch from a horizontal state to an inclined state to facilitate the pouring of electrolyte. During the electrolyte pouring process, the baffle 15 can prevent the battery 200 from sliding off the tray 12.

[0087] Optionally, please continue reading Figure 1 The cell unpacking device 100 also includes an electrolyte collection chamber 140, which is located on the frame to collect the electrolyte spilled from the battery 200.

[0088] Continue reading Figure 11 and Figure 12 The positioning fixture 10 also includes a top block 16 and a first follower block 17. The first follower block 17 is connected to the tray 12, and the top block 16 is movably mounted on the bracket 11 along a straight line. When the top block 16 moves relative to the bracket 11, the first follower block 17 follows the top block 16, thereby causing the tray 12 to rotate around the second axis. When the battery 200 needs to switch from a horizontal state to an inclined state, the top block 16 moves relative to the bracket 11, and the first follower block 17 follows the top block 16. The top block 16 drives the tray 12 to move, thus switching the battery 200 from a horizontal state to an inclined state. At this time, the linear movement of the top block 16 can drive the tray 12 to rotate, ensuring the compactness of the positioning fixture 10.

[0089] For some specific implementation methods, please refer to [link / reference]. Figure 11 The top block 16 is provided with a guide groove 161, and the first follower block 17 is provided with a guide post, which is located in the guide groove 161. When the top block 16 moves relative to the bracket 11, the guide post moves in the guide groove 161, and at the same time, the first follower block 17 drives the tray 12 to rotate relative to the bracket 11 around the second axis. With this configuration, when the battery 200 needs to switch from an inclined state to a horizontal state, the top block 16 moves in the opposite direction relative to the bracket 11, and the first follower block 17 drives the tray 12 to rotate in the opposite direction relative to the bracket 11 around the second axis to reset it, without the need for a separate reset structure for the tray 12. It is conceivable that in other specific embodiments, the top block 16 and the first follower block 17 can be set in other ways, such as setting the top block 16 and the first follower block 17 not to be directly connected. When the battery 200 needs to switch from a horizontal state to a tilted state, the top block 16 moves close to the first follower block 17 and contacts the first follower block 17. Under the pushing action of the top block 16, the first follower block 17 drives the support plate 12 to rotate around the second axis. When the battery 200 needs to switch from a tilted state to a horizontal state, the top block 16 moves away from the first follower block 17. The first follower block 17 and the support plate 12 are reset under the action of gravity or by a separately provided reset member.

[0090] Further reading Figure 11 and Figure 12 The baffle 15 is rotatably mounted on the bracket 11 around a third axis, allowing it to switch between a blocking state that blocks the battery 200 and a releasing state that releases the battery 200. The positioning fixture 10 also includes a second follower block 18. When the top block 16 moves relative to the bracket 11, the second follower block 18 moves with the top block 16, causing the baffle 15 to switch from a releasing state to a blocking state. In this embodiment, when the top block 16 moves along a straight line relative to the bracket 11, both the first follower block 17 and the second follower block 18 move with the top block 16. The first follower block 17 drives the tray 12 to rotate around the second axis, causing the battery 200 to switch from a horizontal state to an inclined state. The second follower block 18 abuts against the baffle 15, causing the baffle 15 to switch from a releasing state to a blocking state, thus preventing the battery 200 from sliding off the tray 12.

[0091] In some specific embodiments, the second axis and the third axis are the same axis. See further details. Figure 11 The positioning fixture 10 also includes a rotating shaft 1102, and both the support plate 12 and the baffle 15 are connected to the bracket 11 via the rotating shaft 1102. It should be understood that in some other embodiments, the second axis and the third axis may also be two different axes.

[0092] Optionally, please continue reading Figure 6The positioning fixture 10 also includes an elastic element 19, which is used to switch the baffle 15 from a blocking state to a releasing state. After the electrolyte is poured out, the tray 12 drives the battery 200 from a tilted state to a horizontal state, and the baffle 15 is reset under the action of the elastic element 19 for the next use.

[0093] It should be noted that, in addition to the above-described setup, the positioning fixture 10 can also be set up in other ways, as long as it has the function of positioning the battery 200 and driving the battery 200 to rotate relative to the conveying mechanism 20 to pour the electrolyte.

[0094] In some embodiments, see Figure 13 The top cover cutting mechanism 30 includes a saw blade lifting assembly 31 and a saw blade assembly 32 connected to each other. The saw blade lifting assembly 31 drives the saw blade assembly 32 to move up and down, and the saw blade of the saw blade assembly 32 can rotate to cut the top cover 201 of the battery 200. In this configuration, when the battery 200 flows to the top cover cutting station B with the positioning fixture 10, the saw blade lifting assembly 31 drives the saw blade assembly 32 to move, and the saw blade of the saw blade assembly 32 rotates to cut the top cover 201. Optionally, the top cover cutting mechanism 30 also includes a top cover collection chamber 33, into which the top cover 201 cut by the saw blade assembly 32 falls for collection.

[0095] It should be understood that in some other embodiments, there is no limitation on how the top cover cutting mechanism 30 is set. For example, the top cover cutting mechanism 30 may also be set to include a cutter lifting assembly and a cutter, with the cutter lifting assembly driving the cutter to lift and cut the top cover 201.

[0096] In some embodiments, see Figure 14 The bottom cover cutting mechanism 40 includes a milling cutter feed assembly 41 and a milling cutter assembly 42 connected to each other. The milling cutter feed assembly 41 is used to drive the milling cutter assembly 42 to cut the casing of the battery 200.

[0097] It is conceivable that in other embodiments, there is no limitation on how the bottom cover cutting mechanism 40 is set, as long as it can be set in a way that can cut through the bottom cover 202 of the battery 200 to form a through hole.

[0098] Further reading Figure 2 and Figure 14The battery cell unpacking device 100 also includes a toggle mechanism 150 and a second blocking mechanism 160 mounted on a frame. The toggle mechanism 150 and the second blocking mechanism 160 are positioned corresponding to the bottom cover cutting station D. The toggle mechanism 150 is used to toggle the battery 200 on the positioning fixture 10. The positioning fixture 10 also includes a limiting block 1101, which is connected to the support plate 12. The toggle mechanism 150 can toggle the battery 200 until the bottom cover 202 abuts against the limiting block 1101. When the bottom cover 202 abuts against the limiting block, it indicates that the battery 200 is at the bottom cover 202 cutting position, and the bottom cover cutting mechanism 40 can then cut the bottom cover 202. This configuration ensures that the bottom cover 202 of each battery 200 is at the bottom cover 202 cutting position, guaranteeing the cutting effect. The actuating mechanism 150 can also actuate one end of the battery 200 to abut against the second blocking mechanism 160, which is used to limit the battery 200. After the bottom cover 202 is cut, the actuating mechanism 150 actuates the battery 200 so that the top cover 201 of the battery 200 abuts against the second blocking mechanism 160, so as to avoid interference between the battery 200 and other structures when it moves to the subsequent work station.

[0099] Optionally, please continue reading Figure 14 The actuating mechanism 150 includes a pawl drive assembly 1501 and a pawl 1502 connected to each other. The pawl drive assembly 1501 drives the pawl 1502 to move, thereby actuating the battery 200. The second blocking mechanism 160 includes a second stop 1601 and a second stop drive assembly 1602 connected to each other. The second stop drive assembly 1602 drives the second stop 1601 to move to block and limit the battery 200.

[0100] In some embodiments, see Figure 15 The ejection mechanism 50 includes a push rod 51 and at least one stage of push rod translation assembly 52. ​​The push rod translation assembly 52 drives the push rod 51 to move, allowing the push rod 51 to pass through a through hole and eject the battery cell from the housing. Specifically, the ejection mechanism 50 includes two stages of push rod translation assembly 52, namely a first stage push rod translation assembly 52 and a second stage push rod translation assembly 52. ​​The push rod 51 is connected to the second stage push rod translation assembly 52. ​​The first stage push rod translation assembly 52 drives the second stage push rod translation assembly 52 to move, and the second stage push rod translation assembly 52 drives the push rod 51 to move, thus ejecting the battery cell from the housing. In other embodiments, the number of stages of push rod translation assembly 52 included in the ejection mechanism 50 can be selected as needed.

[0101] Continue reading Figure 9 The rejection mechanism 60 includes a second push plate 61 and a second push plate drive assembly 62 connected to each other. The second push plate drive assembly 62 is used to drive the second push plate 61 to move and push the housing, so that the housing is disengaged from the positioning fixture 10.

[0102] It should be noted that the power source providing driving force in the above-mentioned lifting assembly, drive assembly, feed assembly, and translation assembly can be a motor or cylinder, etc., and is not limited here.

[0103] The working principle of the battery cell decasing device 100 provided in the specific embodiment of this application is as follows:

[0104] The turntable 21, acting as the conveying mechanism 20, drives the positioning fixture 10 to rotate around the first axis. When the positioning fixture 10 moves to the battery loading station A, the battery 200 is loaded onto the tray 12 of the positioning fixture 10. The first stop drive assembly 132 drives the first stop 1301 to extend, and the first push plate drive assembly 122 drives the first push plate 121 to push the bottom cover 202 of the battery 200 until the top cover 201 of the battery 200 abuts against the first stop 1301, completing the positioning of the battery 200. The first stop 1301 and the first push plate 121 retract, and the clamping assembly 13 of the positioning fixture 10 clamps the battery 200.

[0105] The battery 200 is transferred to the top cover cutting station B along with the positioning fixture 10. The saw blade lifting assembly 31 drives the saw blade assembly 32 to rise and fall, and the top cover 201 of the battery 200 is cut by the saw blade assembly 32.

[0106] The battery 200 is transferred to the electrolyte pouring station C by the positioning fixture 10. The top block 16 of the positioning fixture 10 moves relative to the support 11, and the first follower block 17 and the second follower block 18 follow suit. The tray 12 and the clamping assembly 13 rotate around the second axis, causing the battery 200 to switch from a horizontal state to an inclined state. The baffle 15 prevents the battery 200 from sliding off the tray 12 under the action of the second follower block 18, and the electrolyte is poured into the electrolyte collection chamber 140. After the electrolyte is poured, the top block 16 resets, and the baffle 15 resets under the action of the elastic member 19.

[0107] Battery 200 is transferred to bottom cover cutting station D by positioning fixture 10. Clamping assembly 13 releases battery 200, and pawl drive assembly 1501 drives pawl 1502 to move and move battery 200. The bottom cover 202 of battery 200 abuts against the limiting block 1101 of positioning fixture 10, and clamping assembly 13 clamps battery 200. Milling cutter feed assembly 41 drives milling cutter assembly 42 to feed and mill a through hole on bottom cover 202 of battery 200. Clamping assembly 13 releases battery 200, second stop block drive assembly 1602 drives second stop block 1601 to extend, and pawl drive assembly 1501 drives pawl 1502 to move battery 200 back, so that one end of top cover 201 of battery 200 abuts against second stop block 1601. Battery 200 is repositioned, clamping assembly 13 clamps battery 200, and second stop block 1601 resets.

[0108] The battery 200 is transferred to the cell ejection station by the positioning fixture 10. The push rod translation component 52 drives the push rod 51 to move and eject the cell out of the casing through the through hole.

[0109] The battery cell is transferred to the housing rejection station F by the positioning fixture 10. The clamping assembly 13 releases the battery 200, and the second pusher drive assembly 62 drives the second pusher 61 to move, causing the housing to fall off the positioning fixture 10. The rejection mechanism 60 may also be equipped with a housing collection chamber 63, in which the pushed-off housing falls into the housing collection chamber 63 for collection.

[0110] Another embodiment of this application also provides a battery dismantling device including the above-mentioned cell unpacking device 100. Since the above-mentioned cell unpacking device 100 has beneficial effects, the battery dismantling device has the same beneficial effects, which will not be described in detail here.

[0111] Furthermore, the battery dismantling equipment also includes a Mylar film removal device, located downstream of the cell decasing device 100, for removing the Mylar film from the main surface of the cell.

[0112] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0113] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
