Abstract
Description
Technical Field
[0001] This utility model relates to the field of new energy technology, and in particular to a battery pack plate removal device. Background Technology
[0002] In existing technologies, battery packs need to be disassembled and analyzed during the research and development, testing, trial production, factory production, and after-sales quality processes.
[0003] Among them, disassembling the welded joints of the battery cells and the battery pack is relatively technically difficult. Currently, manual disassembly is commonly used. Due to varying levels of skill, the quality of the disassembled battery cells varies because the cutting depth depends entirely on individual experience when using processing tools to cut the welded joints. This results in greater difficulty, poorer quality of disassembled battery cells, and certain safety hazards. Utility Model Content
[0004] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, the present invention provides a battery pack plate removal device.
[0005] This application provides a battery pack latch removal device, which may include: a support base capable of being mounted on the battery pack position of a vehicle frame; a gantry frame including: a first slide rail, a second slide rail, and a third slide rail, wherein the first slide rail is horizontally mounted on the support base, the second slide rail is horizontally mounted on the first slide rail and can slide along the extension direction of the first slide rail, the extension direction of the second slide rail being perpendicular to the extension direction of the first slide rail, the third slide rail is mounted on the second slide rail and can slide along the extension direction of the second slide rail, the third slide rail having a sliding boss extending vertically; and a mounting plate. The system includes a first sliding groove that slides with the sliding boss; a machining tool mounted on the mounting plate; and a limiting assembly including a limiting plate and a stud. The limiting plate is located on the lower side of the mounting plate, and the limiting plate has a second sliding groove that mates with the sliding boss. In the sliding direction of the mounting plate, the limiting plate can abut against the mounting plate. The side wall of the second sliding groove has a notch, and the outer wall of the notch has a threaded hole. The stud is threaded into the threaded hole, and the stud can extend into the notch and abut against the inner wall of the notch, pushing the inner wall of the notch to deform, so that the inner wall of the second sliding groove abuts against and is fixed to the sliding boss.
[0006] It should be noted that by abutting against the inner wall of the notch, the stud applies pressure to the inner wall of the notch toward the inner side of the second sliding groove, causing the inner wall of the notch to deform inward. This causes the inner wall of the second sliding groove to abut against the side wall of the sliding boss, thus limiting the movement between the limiting plate and the sliding boss. This prevents the limiting plate from moving relative to the sliding boss. Since the limiting plate is located below the mounting plate, when the mounting plate moves to the limiting plate, the limiting plate will block the mounting plate, preventing the mounting plate from moving further downward.
[0007] In actual operation, in order to avoid excessive pressure on the welding positions of the battery cell and the battery chip by the processing tool, a stud is screwed in to limit the downward movement of the mounting plate and restrict the lower limit position of the mounting plate. When the mounting plate moves to the point of contact with the limit plate, the processing tool reaches the height at which the battery cell and the battery chip are welded and disassembled. The processing tool cannot descend further, thus protecting the battery cell and the battery chip and further improving the quality of battery cell disassembly.
[0008] In some embodiments of this application, the sliding boss includes a first sidewall and a second sidewall, the first sidewall and the second sidewall are opposite to each other in the extension direction of the second slide rail, the first sidewall includes a first end edge and a second end edge, the first end edge is connected to the third slide rail, and in the direction from the first end edge to the second end edge, the first sidewall extends obliquely in a direction away from the second sidewall.
[0009] In some embodiments of this application, the second sidewall includes a third end edge and a fourth end edge opposite to each other, the third end edge being connected to the third slide rail, and the second sidewall extending obliquely in a direction away from the first sidewall in the direction of the third end edge toward the fourth end edge.
[0010] In some embodiments of this application, the sliding boss extends to the upper surface of the third slide rail.
[0011] In some embodiments of this application, the sliding boss extends to the lower surface of the third slide rail.
[0012] In some embodiments of this application, the number of the first slide rails is two, and the two first slide rails are spaced apart in the extending direction of the second slide rail.
[0013] In some embodiments of this application, the first slide rail and the second slide rail are slidably connected by a locking slider.

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the solution of this utility model will be further described below. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.
[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present invention, and not all embodiments.
[0029] Currently, battery packs need to be disassembled and analyzed during the research and development, testing, trial production, factory production, and quality after-sales service processes.
[0030] Disassembling the welded joints of the battery cells and batteries is technically challenging and is currently mostly done manually. Due to varying levels of skill, when cutting the welded joints with processing tools, flying debris may be generated and not cleaned up in time, which can easily cause short circuits between the positive and negative electrodes.
[0031] Because the depth of processing depends entirely on personal experience, the quality of the disassembled battery cells also varies, which makes the work more difficult, results in poor quality disassembled battery cells, and poses certain safety hazards.
[0032] To improve the above technical issues, please refer to Figures 1 to 5 This application provides a battery pack tab removal device 100, which may include a support base 110, a gantry frame, a mounting plate 150, a processing tool 160, and a limiting component 170.
[0033] For details, please refer to Figure 1 and Figure 2The support base 110 is mounted on the battery pack position of the vehicle frame. It should be noted that the battery pack position of the vehicle frame generally has a battery pack access port. The support base 110 is mounted on the edge of the access port. The support base 110 has mounting holes that correspond to the holes on the vehicle frame. The quick-locking pin 111 is inserted into the mounting hole to fix the support base 110 to the vehicle frame.
[0034] The gantry frame may include a first slide rail 120, a second slide rail 130, and a third slide rail 140. The first slide rail 120 is horizontally mounted on the support base 110, and the second slide rail 130 is horizontally mounted on the first slide rail 120. The second slide rail 130 can extend along the extension direction of the first slide rail 120 (e.g., along the extension direction of the first slide rail 120). Figure 2 The slide is in the X direction shown, and the extension direction of the second slide rail 130 is (e.g., the X direction shown). Figure 2 The Y direction shown is perpendicular to the extension direction of the first slide rail 120.
[0035] In order to ensure the stability of the sliding of the second slide rail 130, there are two first slide rails 120. The two first slide rails 120 are spaced apart in the extension direction of the second slide rail 130, providing two mounting points for the second slide rail 130. The first slide rail 120 and the second slide rail 130 are connected by a locking slider 132.
[0036] It should be noted that the locking slider 132 has a locked state and an unlocked state. When the locking slider 132 is in the unlocked state, the second slide rail 130 can slide relative to the first slide rail 120. When the locking slider 132 is in the locked state, the second slide rail 130 is fixed in position relative to the first slide rail 120.
[0037] Please continue to refer to this. Figure 1 and Figure 2 In order to prevent the second slide rail 130 from slipping off the end of the first slide rail 120, a first baffle 121 can be provided at the end of the first slide rail 120 in the specific implementation process.
[0038] The third slide rail 140 is mounted on the second slide rail 130 and can slide along the extending direction of the second slide rail 130. To prevent the third slide rail 140 from slipping off the end of the second slide rail 130, a second baffle 131 can be provided at the end of the second slide rail 130 in specific implementation. The third slide rail 140 is also provided with a sliding boss 141, which is vertical (e.g., in the direction of...). Figure 2 (Extends in the Z direction as shown).
[0039] The mounting plate 150 is provided with a first sliding groove that slides in conjunction with the sliding boss 141. Specifically, the first sliding groove is formed as a groove with open ends and is fitted onto the sliding boss 141, thereby enabling the mounting plate 150 to slide relative to the third slide rail 140. The machining tool 160 is mounted on the mounting plate 150, thereby allowing the machining tool 160 to move vertically.
[0040] It should be noted that the first slide rail 120 and the second slide rail 130 are on the horizontal plane (e.g., Figure 2 The slide rail 120 extends along the plane defined by the XY axes shown in the diagram, and the extension direction of the first slide rail 120 is perpendicular to the extension direction of the second slide rail 130. The third slide rail 140 can slide along the extension direction of the second slide rail 130, and the machining tool 160 can slide vertically along the third slide rail 140. With the extension direction of the first slide rail 120 as the first direction, the extension direction of the second slide rail 130 as the second direction, and the vertical direction as the third direction, the first direction, the second direction, and the third direction are perpendicular to each other, so that the machining tool 160 can perform three-dimensional positioning in the machining space. Specifically, it realizes the positioning of the welding joint of the battery cell 200 and the plate 300 in the battery pack.
[0041] Please see Figure 6 and refer to Figures 2 to 5 The limiting component 170 may include a limiting plate 171 and a stud 172. The limiting plate 171 is located on the lower side of the mounting plate 150. At least a portion of the limiting plate 171 projected onto the mounting plate 150 is located outside the first sliding groove. The limiting plate 171 is provided with a second sliding groove 1711 that mates with the sliding boss 141. In the sliding direction of the mounting plate 150, the limiting plate 171 can abut against the mounting plate 150. The side wall of the second sliding groove 1711 is provided with a notch 1712. The outer wall of the notch 1712 is provided with a threaded hole. The stud 172 is threadedly engaged with the threaded hole. The stud 172 can extend into the notch 1712 and abut against the inner wall of the notch 1712, pushing the inner wall of the notch 1712 to deform, so that the inner wall of the second sliding groove 1711 abuts against and is fixed to the sliding boss 141.
[0042] It should be noted that by screwing in the stud 172, the contact between the stud 172 and the inner wall of the notch 1712 causes the stud 172 to apply pressure towards the inner side of the second sliding groove 1711, causing the inner wall of the notch 1712 to deform inward. This causes the inner wall of the second sliding groove 1711 to abut against the side wall of the sliding boss 141, thus limiting the movement between the limiting plate 171 and the sliding boss 141. This prevents the limiting plate 171 from moving relative to the sliding boss 141. Since the limiting plate 171 is located below the mounting plate 150, when the mounting plate 150 moves to the limiting plate 171, the limiting plate 171 will block the mounting plate 150, preventing the mounting plate 150 from moving further downward.
[0043] In actual operation, to avoid excessive pressure on the welding positions of the battery cell 200 and the electrode 300 by the machining tool 160, the limiting plate 171 is screwed in to limit the downward movement of the mounting plate 150 by the screw stud 172. This limits the lower limit position of the mounting plate 150. When the mounting plate 150 moves to abut against the limiting plate 171, the machining tool 160 reaches the height at which the welding positions of the battery cell 200 and the electrode 300 are disassembled. The machining tool 160 cannot descend further, thus protecting the battery cell 200 and the electrode 300 and further improving the quality of disassembling the battery cell 200.
[0044] In some embodiments of this application, the sliding boss 141 includes a first sidewall and a second sidewall. The first sidewall and the second sidewall are opposite to each other in the extension direction of the second slide rail 130. The first sidewall includes a first end edge and a second end edge that are opposite to each other. The first end edge is connected to the third slide rail 140. In the direction from the first end edge to the second end edge, the first sidewall extends obliquely in a direction away from the second sidewall.
[0045] Therefore, by tilting the first sidewall, the mounting plate 150 and the limiting plate 171 can be prevented from falling off from the protruding direction of the sliding boss 141.
[0046] Furthermore, the second sidewall includes opposing third and fourth end edges, the third end edge being connected to the third slide rail 140, and the second sidewall extending obliquely in the direction from the third end edge to the fourth end edge, away from the first sidewall.
[0047] Therefore, the cross-section of the sliding boss 141 is formed into a trapezoid, which further prevents the mounting plate 150 and the limiting plate 171 from falling off from the protruding direction of the sliding boss 141.
[0048] Furthermore, the sliding boss 141 can extend to the upper surface of the third slide rail 140, so that the first sliding groove can be fitted over the outer side of the sliding boss 141 through the upper end of the sliding boss 141, thereby achieving a sliding connection between the mounting plate 150 and the sliding boss 141.
[0049] Furthermore, the sliding boss 141 can extend to the lower surface of the third slide rail 140, so that the second sliding groove 1711 can be fitted onto the outside of the sliding boss 141 through the lower end of the sliding boss 141, thereby connecting the limiting plate 171 and the sliding boss 141.
[0050] In some embodiments of this application, please refer to Figure 5 and Figure 6 The sliding boss 141 is provided with a rack 142, which extends along the extension direction of the sliding boss 141; the mounting plate 150 is provided with an adjustment hole, which penetrates the side wall of the first sliding groove.
[0051] The battery strip removal device may also include a hand lever 190, which includes an adjustment section and a hand section connected to each other. The hand section is located outside the mounting plate 150, and the adjustment section extends into the first sliding groove through the adjustment hole. The outer circumferential side of the adjustment section is provided with teeth that cooperate with the rack 142.
[0052] Thus, by rotating the hand lever 190, the mounting plate 150 can move relative to the sliding boss 141. Specifically, the mounting plate 150 has a scale on one side surface of the hand grip section, which can be used to identify the descent height of the mounting plate 150, and thus identify the descent height of the machining tool 160.
[0053] Furthermore, the free end of the handheld section is equipped with a handle, which improves the efficiency of the operator in rotating the handheld lever 190 degrees. Specifically, the handle can be a crank handle or a steering wheel handle.
[0054] In some embodiments of this application, the battery pack strip removal device 100 may further include a controller 180, which is electrically connected to the drive motor of the machining tool 160 and is used to control the start and stop of the machining tool 160.
[0055] In some embodiments of this application, the battery pack strip removal device 100 may further include a mounting base 101, a processing tool 160 disposed on the mounting base 101, and the mounting base 101 mounted on the mounting plate 150.
[0056] In some embodiments of this application, the battery pack strip removal device 100 may also include an external vacuum cleaner to promptly remove processing debris and prevent short circuit accidents between the positive and negative terminals.
