[0002] In the manufacturing process of prismatic lithium batteries, formation and capacity testing are crucial steps. To improve equipment utilization efficiency, charging and discharging equipment typically needs to be compatible with different battery models and sizes. Key components on the charging and discharging equipment, such as probe assemblies for electrical connections and negative pressure assemblies for vacuuming, need to be frequently repositioned according to changes in battery models.

[0003] In related technologies, the positive electrode probe, negative electrode probe, and negative pressure component usually share a set of switching mechanisms for linkage adjustment. When the relative positions of the positive electrode, negative electrode, and injection hole of the battery change, the negative pressure component cannot be adjusted independently. It is necessary to disassemble and calibrate twice, which makes the debugging process complicated. Furthermore, the switching mechanism includes a drive component and an adjustment component. The drive component and the adjustment component are usually set along the Z direction. Therefore, there is a height difference between the drive component and the adjustment component. Due to the height problem, a transmission component is set up for the two, which increases the number of parts in the switching mechanism and increases the installation difficulty.

[0028] First, it should be noted that the X, Y, and Z directions mentioned in the embodiments of this application are referred to in the appendix. Figure 1 and Figure 4 The marked directions. Among them, the axes in the X direction, Y direction, and Z direction intersect each other.

[0029] like Figures 1-10 As shown, according to a first aspect of the embodiments of this application, a shape-changing device is provided, including a first shape-changing mechanism 1, a second shape-changing mechanism 2, a probe assembly 4, and a negative pressure assembly 5; the first shape-changing mechanism 1 includes a first driving assembly 11 and a first adjusting assembly 12, the first adjusting assembly 12 including a first fixing structure 121 connected to the first driving assembly 11, the first driving assembly 11 including a first output shaft, the axis of the first output shaft coinciding with the axis of the first fixing structure 121; the second shape-changing mechanism 2 is arranged at intervals from the first shape-changing mechanism 1 along the X direction and at the same height in the Z direction, the second shape-changing mechanism 2 including a second driving assembly 21 and a second adjusting assembly 22, the second adjusting assembly 22 including a third fixing structure 221 connected to the second driving assembly 21, the second driving assembly 21 including a second output shaft, the axis of the second output shaft coinciding with the axis of the third fixing structure 221; the probe assembly 4 is connected to the first fixing structure 121; the negative pressure assembly 5 is connected to the third fixing structure 221.

[0030] like Figure 1 and Figure 2 As shown, the shape-changing device includes a first shape-changing mechanism 1, a second shape-changing mechanism 2, a probe assembly 4, and a negative pressure assembly 5; wherein, the first shape-changing mechanism 1 and the second shape-changing mechanism 2 are spaced apart along the X direction, the first shape-changing mechanism 1 is used to adjust the probe assembly 4, and the second shape-changing mechanism 2 is used to adjust the negative pressure assembly 5.

[0031] like Figure 2 and Figure 4As shown, the first changing mechanism 1 includes a first driving component 11 and a first adjusting component 12. The first adjusting component 12 includes a first fixing structure 121, which is connected to the driving end of the first driving component 11. The probe component 4 is connected to the first fixing structure 121. The first driving component 11 can drive the probe component 4 to move along the X direction through the first fixing structure 121. The second changing mechanism 2 includes a second driving component 21 and a second adjusting component 22. The second adjusting component 22 includes a third fixing structure 221, which is connected to the driving end of the second driving component 21. The negative pressure component 5 is connected to the third fixing structure 221. The second driving component 21 can drive the negative pressure component 5 to move along the X direction through the third fixing structure 221.

[0032] Further explanation: The first drive assembly 11 includes a first output shaft, the axis of which coincides with the axis of the first fixed structure 121. Specifically, the axis of the first output shaft is parallel to the axis in the X direction, and the axis of the first fixed structure 121 is also parallel to the axis in the X direction. The first output shaft is connected to the first fixed structure 121. Therefore, in the Z direction, the first output shaft and the first fixed structure 121 are at the same height and coaxially arranged. Thus, there is no need to set up a transmission structure between the first drive assembly 11 and the first fixed structure 121 due to height issues, thereby reducing the number of parts in the first changing mechanism 1, reducing installation difficulty, and improving debugging. Efficiency; the second drive assembly 21 includes a second output shaft, the axis of which coincides with the axis of the third fixed structure 221; specifically, the axis of the second output shaft is parallel to the axis in the X direction, and the axis of the third fixed structure 221 is parallel to the axis in the X direction. The second output shaft is connected to the third fixed structure 221, so the second output shaft and the third fixed structure 221 are at the same height and coaxially arranged in the Z direction. Therefore, there is no need to set a transmission assembly between the second drive assembly 21 and the third fixed structure 221 due to height issues, thereby reducing the number of parts in the second changing mechanism 2, reducing installation difficulty, and improving debugging efficiency.

[0033] The battery replacement device provided in this application has an independent first adjustment component 12 and a second adjustment component 22. The positions of the probe component 4 and the negative pressure component 5 can be adjusted independently through the first adjustment component 12 and the second adjustment component 22, respectively. There is no need to disassemble and assemble parts for two calibration operations, which simplifies the battery replacement debugging process, shortens the downtime of charging and discharging equipment replacement, and thus effectively improves the production efficiency of charging and discharging equipment. In addition, there is no need to set up a transmission structure between the first drive component 11 and the first fixed structure 121 due to height issues, and there is no need to set up a transmission component between the second drive component 21 and the third fixed structure 221 due to height issues. This reduces the number of parts in the first replacement mechanism 1 and the second replacement mechanism 2, reduces the installation difficulty, and improves debugging efficiency.

[0034] In the prior art, the changing mechanism is usually installed on the side 61 of the top frame 6. In order to ensure the installation accuracy of the changing mechanism, it is necessary to perform precision machining on the side 61. However, machining the side 61 requires rotating the entire top frame 6 90 degrees horizontally, and the machining process of the side 61 is relatively complicated and troublesome.

[0035] In response to the above problems, such as Figures 1-3 As shown, in an optional embodiment of this application, the battery changing device further includes a first mounting plate 7 and a top frame 6. The first mounting plate 7 is disposed on the side 61 of the top frame 6, and the first changing mechanism 1 and the second changing mechanism 2 are both disposed on the bottom surface 71 of the first mounting plate 7. Specifically, the top frame 6 includes a side 61 facing the Y direction, the first mounting plate 7 is fixedly mounted on the side 61 of the top frame 6, the first mounting plate 7 has a bottom surface 71 facing the Z direction, and the first changing mechanism 1 and the second changing mechanism 2 are spaced apart on the bottom surface 71 of the first mounting plate 7 along the X direction. In this embodiment, the bottom surface 71 of the first mounting plate 7 is easier to be precision machined, thereby reducing the processing difficulty of the changing device and ensuring the flatness of the bottom surface 71 of the first mounting plate 7. By mounting the first changing mechanism 1 and the second changing mechanism 2 on the bottom surface 71 of the first mounting plate 7, the installation accuracy of the first changing mechanism 1 and the second changing mechanism 2 can be improved, thereby improving the horizontal accuracy of the probe assembly 4 and the negative pressure assembly 5, reducing the alignment deviation during battery changing, and reducing the debugging difficulty.

[0036] Among them, the bottom surface 71 of the first mounting plate 7 is a precision-machined plane.

[0037] like Figure 2 , Figure 4 and Figure 5As shown, in an optional embodiment, the first adjusting assembly 12 further includes a second fixing structure 122 and a first transmission structure 123. The first fixing structure 121 and the second fixing structure 122 are spaced apart along the Y direction, and the first driving assembly 11 is connected to the first fixing structure 121. Both ends of the first transmission structure 123 are respectively connected to the first fixing structure 121 and the second fixing structure 122, and both ends of the probe assembly 4 are respectively connected to the first fixing structure 121 and the second fixing structure 122. Specifically, the first fixing structure 121 and the second fixing structure 122 are spaced apart along the Y direction, and the first transmission structure 123 includes a first transmission part and a... The second transmission unit is connected to the first fixed structure 121 and the second fixed structure 122. One end of the probe assembly 4 is movably connected to the first fixed structure 121 and the other end of the probe assembly 4 is movably connected to the second fixed structure 122. The driving end of the first driving assembly 11 is connected to the end of the first fixed structure 121 away from the first transmission structure 123. In this embodiment, the first fixed structure 121 and the second fixed structure 122 are driven by the first transmission structure 123, which enables the two ends of the probe assembly 4 to move synchronously in the X direction. This improves the uniformity of force and the consistency of displacement at both ends of the probe assembly 4 during the adjustment process, thereby avoiding the problem of unilateral offset and tilt of the probe assembly 4.

[0038] like Figure 6 and Figure 7 As shown, in a specific embodiment, the first transmission structure 123 includes a first gear 1231, a second gear 1232, a third gear, a fourth gear 1234, and a transmission shaft 1235. The first gear 1231 is located at one end of the first fixed structure 121, the second gear 1232 is located at one end of the second fixed structure 122, the third gear is located at one end of the transmission shaft 1235, and the fourth gear 1234 is located at the other end of the transmission shaft 1235. The first gear 1231 meshes with the third gear, and the second gear 1232 meshes with the fourth gear 1234. Power transmission is achieved through gear meshing.

[0039] Among them, the first gear 1231, the second gear 1232, the third gear, and the fourth gear 1234 can be helical gears or spur gears.

[0040] Among them, the first gear 1231 and the third gear are the first transmission part; the second gear 1232 and the fourth gear 1234 are the second transmission part.

[0041] like Figure 2 , Figure 4 and Figure 8As shown, in an optional embodiment, the second adjusting component 22 further includes a fourth fixing structure 222 and a second transmission structure 223. The third fixing structure 221 and the fourth fixing structure 222 are spaced apart along the Y direction, and the second driving component 21 is connected to the third fixing structure 221. The two ends of the second transmission structure 223 are respectively connected to the third fixing structure 221 and the fourth fixing structure 222, and the two ends of the negative pressure component 5 are respectively connected to the third fixing structure 221 and the fourth fixing structure 222. Specifically, the third fixing structure 221 and the fourth fixing structure 222 are spaced apart along the Y direction, and the second transmission structure 223 includes a third transmission part arranged along the Y direction. The third and fourth transmission parts are connected to the third fixed structure 221 and the fourth transmission part is connected to the fourth fixed structure 222. One end of the negative pressure component 5 is movably connected to the third fixed structure 221 and the other end of the negative pressure component 5 is movably connected to the fourth fixed structure 222. The driving end of the second driving component 21 is connected to the end of the third fixed structure 221 away from the second transmission structure 223. In this embodiment, the third fixed structure 221 and the fourth fixed structure 222 are driven by the second transmission structure 223, which enables the two ends of the negative pressure component 5 to move synchronously in the X direction. This improves the uniformity of force and the consistency of displacement at both ends of the negative pressure component 5 during the adjustment process, thereby avoiding the problem of unilateral offset and tilt of the negative pressure component 5.

[0042] The structure of the second transmission structure 223 is the same as that of the first transmission structure 123, and will not be described again here.

[0043] like Figure 4 and Figure 5 As shown, in one specific embodiment, the first drive assembly 11 and the first fixed structure 121 are arranged along the X direction, and the second drive assembly 21 and the third fixed structure 221 are arranged along the X direction. The first drive assembly 11 and the second drive assembly 21 are located between the first fixed structure 121 and the third fixed structure 221. Specifically, the first fixed structure 121, the first drive assembly 11, the second drive assembly 21 and the third fixed structure 221 are arranged sequentially along the X direction. The first drive assembly 11 and the second drive assembly 21 are located between the first fixed structure 121 and the third fixed structure 221. In other words, the first drive assembly 11 and the second drive assembly 21 are located in the middle position at the front of the changing device, which facilitates the operator to inspect and maintain the first drive assembly 11 and the second drive assembly 21.

[0044] To further explain, the length of the first driving component 11 extends along the X direction, and the length of the second driving component 21 extends along the X direction; that is, the length direction of the first driving component 11 is also the X direction, and the length direction of the second driving component 21 is also the X direction. In this embodiment, the space occupied by the first driving component 11 and the second driving component 21 in the Z direction can be reduced.

[0045] like Figure 2 and Figure 5 As shown, in one specific embodiment, both the first fixing structure 121 and the second fixing structure 122 include a first adjusting member 1211 and a second adjusting member 1212. The probe assembly 4 includes a positive probe 41 and a negative probe 42. The positive probe 41 is connected to the first adjusting member 1211, and the negative probe 42 is connected to the second adjusting member 1212. The direction in which the first adjusting member 1211 moves the positive probe 41 is opposite to the direction in which the second adjusting member 1212 moves the negative probe 42. Specifically, the first adjusting member 1211 is connected to the first driving assembly 11, and the second adjusting member 1212... 12 is connected to the first adjusting member 1211. One end of the positive probe 41 is connected to the first adjusting member 1211 of the first fixing structure 121, and the other end of the positive probe 41 is connected to the first adjusting member 1211 of the second fixing structure 122. One end of the negative probe 42 is connected to the second adjusting member 1212 of the first fixing structure 121, and the other end of the negative probe 42 is connected to the second adjusting member 1212 of the second fixing structure 122. The positive probe 41 and the negative probe 42 can be moved towards or away from each other in the X direction through the first adjusting member 1211 and the second adjusting member 1212 to adjust the distance between the positive probe 41 and the negative probe 42.

[0046] like Figure 2 and Figure 8 As shown, to further illustrate, both the third fixing structure 221 and the fourth fixing structure 222 include a third adjusting member 2211, and the negative pressure component 5 is connected to the third adjusting member 2211; specifically, one end of the negative pressure component 5 is connected to the third adjusting member 2211 of the third fixing structure 221, and the other end of the negative pressure component 5 is connected to the third adjusting member 2211 of the fourth fixing structure 222.

[0047] In the above embodiment, in the X direction, the negative pressure component 5 is located between the positive electrode probe 41 and the negative electrode probe 42. The first driving component 11 drives the first adjusting member 1211 and the second adjusting member 1212 to move the positive electrode probe 41 and the negative electrode probe 42 toward or away from each other, so as to adjust the distance between the positive electrode probe 41 and the negative electrode probe 42 in the X direction. The second driving component 21 drives the third adjusting member 2211 to move the negative pressure component 5 in the X direction, so as to adjust the distance between the negative pressure component 5 and the positive electrode probe 41 or the negative electrode probe 42 individually. Different batteries can be adapted without disassembly and calibration. It has a high degree of adjustment freedom and the replacement and debugging steps are simpler.

[0048] like Figure 9 As shown, in one specific embodiment, both the first adjusting member 1211 and the second adjusting member 1212 include a first lead screw 12111, a first fixing block 12112, a second mounting plate 12113, and a first movable member 12114. The first movable member 12114 is rotatably engaged with the first lead screw 12111, the second mounting plate 12113 is detachably connected to the first movable member 12114, and the first fixing block 12112 is connected to the second mounting plate 12113. The probe assembly 4 is connected to the first fixing block 12112; specifically, the first movable member 12114 is rotatably engaged with the first lead screw 12111, the second mounting plate 12113 is connected to the first movable member 12114, the first fixing block 12112 is detachably connected to the second mounting plate 12113, and the probe assembly 4 is connected to the first fixing block 12112; the first drive assembly 11 can drive the first lead screw 12111 to rotate around the axis in the X direction, and the first movable member 12114 can be relatively fixed relative to the first... The lead screw 12111 moves along the X direction, thereby enabling the probe assembly 4 to move along the X direction via the second mounting plate 12113 and the first fixing block 12112. When the position of the first movable member 12114 needs to be adjusted separately, the first fixing block 12112 can be removed from the second mounting plate 12113, preventing the probe assembly 4 from affecting the rotation of the first movable member 12114, thus allowing manual adjustment of the position of the first movable member 12114. The first lead screw 1211 of the first adjusting member 1211... 1. Connected to the first output shaft of the first drive assembly 11, the first lead screw 12111 of the second adjusting member 1212 is connected to the first lead screw 12111 of the first adjusting member 1211, and the thread direction of the first lead screw 12111 on the first adjusting member 1211 is opposite to the thread direction of the first lead screw 12111 on the second adjusting member 1212, so that the first movable member 12114 of the first adjusting member 1211 and the first movable member 12114 of the second adjusting member 1212 can move towards or away from each other.

[0049] The axis of the first fixed structure 121 is the axis of the first lead screw 12111 of the first adjusting member 1211. In other words, the axis of the first output shaft of the first drive assembly 11 coincides with the axis of the first lead screw 12111.

[0050] Further explanation: The third adjusting component 2211 includes a second lead screw (not shown in the figure), a second fixed block (not shown in the figure), a third mounting plate (not shown in the figure), and a second movable component (not shown in the figure). The second movable component is rotatably engaged with the second lead screw, the third mounting plate is connected to the second movable component, the second fixed block is detachably connected to the third mounting plate, and the negative pressure component 5 is connected to the second fixed block. Specifically, the second movable component is rotatably engaged with the second lead screw, the third mounting plate is connected to the second movable component, the second fixed block is detachably connected to the third mounting plate, and the negative pressure component 5 is connected to the second fixed block. The second driving component 21 can drive the second lead screw to rotate around the X-axis, and the second movable component can move relative to the second lead screw along the X-axis, thereby enabling the negative pressure component 5 to move along the X-axis via the third mounting plate and the second fixed block. When it is necessary to adjust the position of the second movable component separately, simply remove the second fixed block from the third mounting plate to avoid the negative pressure component 5 affecting the rotation of the second movable component, thus allowing manual adjustment of the position of the second movable component.

[0051] The axis of the third fixed structure 221 is the axis of the second lead screw of the third adjusting member 2211. In other words, the axis of the second output shaft of the second drive assembly 21 coincides with the axis of the second lead screw.

[0052] In one specific embodiment, the first fixing block 12112 has a first elongated hole 12115, the Z-direction dimension of the first elongated hole 12115 is larger than the Y-direction dimension of the first elongated hole 12115, and the second mounting plate 12113 has a first connecting hole 12116 corresponding to the first elongated hole 12115.

[0053] In another specific embodiment, the second fixing block has a second elongated hole, the Z-direction dimension of the second elongated hole is greater than the Y-direction dimension of the second elongated hole, and the third mounting plate has a second connecting hole corresponding to the second elongated hole.

[0054] like Figure 2 and Figure 9As shown, in another specific embodiment, the first fixing block 12112 has a first elongated hole 12115, the Z-direction dimension of the first elongated hole 12115 being larger than the Y-direction dimension of the first elongated hole 12115; the second mounting plate 12113 has a first connecting hole 12116 corresponding to the first elongated hole 12115; the second fixing block has a second elongated hole, the Z-direction dimension of the second elongated hole being larger than the Y-direction dimension of the second elongated hole; and the third mounting plate has a second connecting hole corresponding to the second elongated hole. This embodiment will be described as an example.

[0055] Specifically, the first fixing block 12112 has a first elongated hole 12115, the axis of which is parallel to the axis in the X direction. The first elongated hole 12115 has a first dimension in the Z direction and a second dimension in the Y direction, where the first dimension is larger than the second dimension. The second mounting plate 12113 has a first connecting hole 12116, which corresponds to the first elongated hole 12115. The first connecting hole 12116 can be a round hole or an elongated hole for fastening. The first fixing block 12112 is fixed together with the second mounting plate 12113 by passing through the first connecting hole 12116 and the first elongated hole 12115. In this embodiment, the first elongated hole 12115 can provide assembly compensation in the Z direction to accommodate dimensional deviations caused by component processing and machining, and avoid assembly interference. At the same time, the fastener can be quickly inserted through the first elongated hole 12115 and the first connecting hole 12116 without precise alignment, and its disassembly and assembly operations are convenient, thereby reducing the difficulty of equipment maintenance, model change and disassembly operations.

[0056] Specifically, the second fixing block has a second elongated hole, the axis of which is parallel to the axis in the X direction. The second elongated hole has a third dimension in the Z direction and a fourth dimension in the Y direction, with the third dimension being larger than the fourth dimension. The third mounting plate has a second connecting hole corresponding to the second elongated hole. The second connecting hole can be a round hole or an elongated hole. Fasteners pass through the second connecting hole and the second elongated hole to fix the second fixing block and the third mounting plate together. In this embodiment, the second elongated hole can provide assembly compensation in the Z direction to accommodate dimensional deviations caused by component processing and machining, and avoid assembly interference. At the same time, the second elongated hole and the second connecting hole do not require precise alignment for fasteners to be quickly inserted, making disassembly and assembly convenient and reducing the difficulty of equipment maintenance and replacement.

[0057] like Figure 1 , Figure 3 and Figure 10As shown, in an optional embodiment, the changing device further includes a third changing mechanism 3 and a lifting frame 8. The third changing mechanism 3 is disposed on the lifting frame 8, and the lifting frame 8 and the top frame 6 are arranged at intervals along the Z direction. The third changing mechanism 3 is configured to adjust the relative lifting stroke between the top frame 6 and the lifting frame 8. Specifically, due to the height variation of the battery and / or tray itself or the thickness difference of different battery models, when it is necessary to adjust the working height of the probe assembly 4 to adapt to batteries or trays of different specifications, the third changing mechanism 3 can adjust the movement range of the lifting frame 8 along the Z direction to be compatible with batteries or trays of different specifications.

[0058] like Figure 1 and Figure 3 As shown, in an optional embodiment, the changing device further includes a limiting member 9, which is disposed on the top frame 6. The third changing mechanism 3 includes a lifting part 33, which is arranged with the limiting member 9 along the Z direction. Specifically, the lifting part 33 has a limiting surface 331 and can move along the Z direction. By moving the lifting part 33 in the Z direction, the distance between the limiting surface 331 and the limiting member 9 can be changed, which in turn can change the range of movement of the lifting frame 8 in the Z direction, thereby realizing flexible adjustment of the working height.

[0059] like Figure 10 As shown, in a specific embodiment, the third changing mechanism 3 includes a third driving component 31 and a transmission component 32. The third driving component 31 is connected to the transmission component 32, and the transmission component 32 is rotatably connected to the lifting part 33. The third driving component 31 can drive the lifting part 33 to move along the Z direction.

[0060] When it is necessary to change the battery model, the operation process of the battery replacement device is as follows: The controller sends instructions to the first drive component 11 and the second drive component 21, adjusts the position of the probe component 4 through the first adjustment component 12, and adjusts the position of the negative pressure component 5 through the second adjustment component 22, so as to realize the battery model that needs to be replaced.

[0061] The controller sends instructions to the third changing mechanism 3 to adjust the position of the lifting unit 33 in the Z direction, thereby achieving height control.

[0062] According to a second aspect of the embodiments of this application, a charging and discharging device is provided, including the above-described replacement device.
