The terminology used herein in the template description is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] like Figures 1 to 4 As shown, some embodiments of this application provide a hydraulic restraint machine having a first direction Z and a second direction Y that are perpendicular to each other, mainly used to improve the flexibility of movement and reduce the transfer time of the electrode assembly.

[0027] The hydraulic restraint machine includes a vehicle body 100, a limiting device 200, and a hydraulic device 300.

[0028] The vehicle body 100 includes a first support plate 110 and a movable part 120. The movable part 120 is disposed on one side of the support plate along the first direction Z, so as to provide movable support for the support plate. The first support plate 110 has a plurality of through holes 111 extending along the first direction Z. The arrangement of the plurality of through holes 111 includes at least one of matrix arrangement, linear arrangement, arc arrangement, and ring arrangement, which can be specifically set according to the actual situation.

[0029] The limiting device 200 is disposed on the side of the first support plate 110 away from the moving part 120 along the first direction Z. The limiting device 200 includes a hydraulic pump 211, a frame 220 and a movable plate 230. The frame 220 defines an installation space 221. The movable plate 230 is at least partially housed in the installation space 221 and is slidably connected to the frame 220 along the second direction Y. The frame 220 provides guidance and limiting for the movable plate 230 along the second direction Y, so as to ensure the stability and smoothness of the sliding of the movable plate 230 in the second direction Y.

[0030] In this embodiment, the hydraulic pump 211 is located on the side of the frame 220 opposite to the movable plate 230 along the second direction Y, and the hydraulic pump 211 is configured to push the movable plate 230 to move relative to the frame 220 along the second direction Y.

[0031] It should be noted that the installation space 221 is used to assemble the cell restraint device. After the cell restraint device is installed in the installation space 221, the hydraulic pump 211 pushes the movable plate 230 to move along the second direction Y. The movable plate 230 abuts against the cell restraint device, thereby restraining the cell placed in the cell restraint device, shaping the cell thickness, ensuring the consistency of the size of the same batch, so that the gas generated during the formation process can be discharged smoothly and suppressing abnormal swelling of the cell.

[0032] Additionally, the hydraulic device 300 includes a lifting platform 320 and a plurality of push rods 330. The lifting platform 320 is disposed on the side of the first support plate 110 away from the limiting device 200, and the push rods 330 are disposed on the side of the lifting platform 320 facing the first support plate 110. Each push rod 330 corresponds one-to-one with a through hole 111 along the first direction Z, meaning the number of push rods 330 is equal to the number of through holes 111, and one push rod 330 can be inserted into one through hole 111. In this embodiment, the axis of the push rod 330 is parallel to the first direction Z.

[0033] In this embodiment, the lifting platform 320 can move along the first direction Z, and the lifting platform 320 drives the top rod 330 to pass through the through hole 111 along the first direction Z, that is, the top rod 330 and the lifting platform 320 move synchronously along the first direction Z. It should be noted that the top rod 330 moves relative to the first support plate 110 along the first direction Z during the process of passing through the through hole 111 along the first direction Z.

[0034] It should be noted that after the battery cell in the battery cell restraint device installed on the frame 220 has completed its formation, the lifting platform 320 drives the top rod 330 through the through hole 111, and the top rod 330 pushes the battery cell out of the battery cell restraint device so that the battery cell after formation can be taken out.

[0035] like Figure 1 As shown, in some embodiments of this application, the hydraulic restraint machine also has a third direction X, and the first direction Z, the second direction Y and the third direction X are mutually perpendicular.

[0036] The frame 220 includes a second support plate 224, multiple connecting rods 222 and a limiting member 223. The second support plate 224 is disposed between the hydraulic pump 211 and the movable plate 230. The second support plate 224 is connected to the first support plate 110 and the second support plate 224 is parallel to the movable plate 230.

[0037] In addition, the limiting member 223 is disposed at one end of the first support plate 110 away from the second support plate 224 along the second direction Y. One end of the connecting rod 222 is connected to the second support plate 224, and the other end of the connecting rod 222 is connected to the limiting member 223. The connecting rod 222 passes through the movable plate 230 along the second direction Y, so as to provide guidance and limiting function for the movable plate 230 during the movement along the second direction Y, so as to ensure the stability of the movable plate 230 during the movement.

[0038] In this embodiment, multiple connecting rods 222 are spaced apart at both ends of the second support plate 224 along the third direction X. At least two connecting rods 222 are spaced apart along the first direction Z and at least two connecting rods 222 are spaced apart along the third direction X. The axis of the connecting rods 222 is parallel to the second direction Y. This forms a limiting structure in the installation space 221 along the third direction X through the multiple connecting rods 222. The connecting rods 222 limit the battery cell restraint device installed in the installation space 221. At the same time, the movable plate 230 and the limiting member 223 limit the battery cell restraint device along the second direction Y to ensure the stability of the battery cell restraint device in the installation space 221.

[0039] like Figure 2 As shown, in some embodiments of this application, the hydraulic restraint machine further includes a jack 213, which is disposed between the second support plate 224 and the movable plate 230, and is connected to the hydraulic pump 211 for transmission. The output end of the jack 213 is connected to the movable plate 230 along the second direction Y, so that the jack 213 can be driven to push the movable plate 230 to move along the second direction Y during the operation of the hydraulic pump 211.

[0040] Understandably, when the cell restraint device is located in the installation space 221, the hydraulic pump 211 is started, and the hydraulic pump 211 drives the jack 213 to extend. The jack 213 pushes the movable plate 230 to move along the second direction Y towards the side close to the limit member 223. The movable plate 230 squeezes the cell restraint device, thereby restraining the cell placed in the cell restraint device along the second direction Y.

[0041] It is understood that in this embodiment, the battery cell restraint device can be directly restrained or released in the installation space 221 by means of the frame 220, which saves the transfer time of the battery cell restraint device between different devices and improves the production efficiency of the restraint process.

[0042] like Figure 2 and Figure 3 As shown, in some embodiments of this application, the limiting member 223 includes a support frame 2231, a support member 2232 and a baffle 2233, with the support frame 2231 disposed on the side of the first support plate 110 away from the moving part 120.

[0043] Among them, the support member 2232 and the baffle 2233 are respectively disposed on the side of the support frame 2231 away from the second support plate 224. The side of the support member 2232 facing the support frame 2231 defines the mounting groove 2234 with the support frame 2231. The mounting groove 2234 passes through the support member 2232 in a third direction X, and the opening of the mounting groove 2234 is disposed away from the first support plate 110.

[0044] In this embodiment, the baffle 2233 is rotatably connected to the support frame 2231, and the baffle 2233 has a first position and a second position relative to the support member 2232.

[0045] When the baffle 2233 is in the first position relative to the support member 2232, a portion of the baffle 2233 is received in the mounting groove 2234. At least a portion of the baffle 2233 is located on the side of the support member 2232 away from the mounting space 221 along the third direction X, so as to limit the battery cell restraint device installed in the mounting space 221 away from the movable plate 230 along the second direction Y by the baffle 2233, thereby limiting the battery cell restraint device along the second direction Y by the movable plate 230 and the baffle 2233 to ensure the stability of the connection between the battery cell restraint device and the frame 220.

[0046] When the baffle 2233 is in the second position relative to the support member 2232, the baffle 2233 is located on the side of the support member 2232 away from the installation space 221. At this time, the baffle 2233 has no limit on the cell restraint device along the second direction Y, so as to facilitate the removal of the cell restraint device from the frame 220.

[0047] like Figure 2 and Figure 3 As shown in some embodiments of this application, the movable plate 230 has a plurality of spaced-apart support columns 400 on the side opposite to the hydraulic pump 211. The arrangement of the plurality of support columns 400 includes at least one of matrix arrangement, linear arrangement, and ring arrangement. The axis of the support column 400 is parallel to the second direction Y.

[0048] In this embodiment, the support column 400 is configured to position the cell restraint device housed in the mounting space 221.

[0049] It should be noted that in this embodiment, the support column 400 is a column of equal height, so as to form a limiting effect on the battery cell restraint device in the first direction Z through the support column 400, so as to achieve precise limiting of the battery cell restraint device and ensure the stability of the battery cell restraint device in the first direction Z.

[0050] like Figure 3 and Figure 4 As shown, in some embodiments of this application, the hydraulic device 300 further includes a cylinder 340, which is disposed on the side facing the first support plate 110.

[0053] The guide rod 350 passes through the lifting platform 320 along the first direction Z, so as to provide guidance and limit the lifting platform 320 along the first direction Z, so as to prevent the lifting platform 320 from shaking during the lifting process along the first direction Z, and to ensure the stability and accuracy of the movement of the lifting platform 320 along the first direction Z.

[0054] In this embodiment, the bearing 360 is disposed on the side of the lifting platform 320 facing the first support plate 110, and the bearing 360 is sleeved on the guide rod 350. In this embodiment, the bearing 360 is a double-liner bearing 360. It should be noted that the double-liner bearing 360 is a structural form of the linear ball bearing 360. The double-liner bearing 360 has the advantages of high load capacity, good rigidity, resistance to eccentric load, and convenient installation.

[0055] In this embodiment, multiple guide rods 350 are spaced apart, and a bearing 360 is fitted onto one guide rod 350 to further improve the stability and accuracy of the lifting platform 320 in the first direction Z.

[0056] In addition, multiple guide rods 350 are disposed at both ends of the first support plate 110 along the second direction Y, and / or multiple guide rods 350 are disposed at both ends of the first support plate 110 along the third direction X.

[0057] It is understood that in some embodiments, a plurality of guide rods 350 are disposed at both ends of the first support plate 110 along the second direction Y, or a plurality of guide rods 350 are disposed at both ends of the first support plate 110 along the third direction X. In other embodiments, a plurality of guide rods 350 are disposed at both ends of the first support plate 110 along the second direction Y, and a plurality of guide rods 350 are disposed at both ends of the first support plate 110 along the third direction X.

[0058] In this embodiment, the arrangement of the multiple guide rods 350 includes at least one of linear arrangement, matrix arrangement, and ring array. By controlling the arrangement of the guide rods 350, the limiting and guiding quality of the guide rods 350 on the movement of the lifting platform 320 along the first direction Z is further ensured, and the shaking of the lifting platform 320 is avoided.

[0059] like Figure 1 and Figure 4 As shown, in some embodiments of this application, the hydraulic device 300 further includes a control component 310. The control component 310 includes a housing 311, a control panel 312, and a power supply 313. The housing 311 is disposed on the side of the first support plate 110 away from the limiting device 200. The connection between the housing 311 and the first support plate 110 includes any one of snap-fit, adhesive, bolt connection, or welding.

[0060] The lifting platform 320 and the power supply 313 are arranged alternately within the housing 311, and the housing 311 has an air supply port 314 on at least one side along the third direction X. It is understood that in some embodiments, the housing 311 has an air supply port 314 on one side along the third direction X.

The control panel 312 is located on one side of the housing 311 along the second direction Y. The control panel 312 is electrically connected to the power supply 313 to provide stable power to the control panel 312. The user can control the start or stop of the cylinder 340 through the control panel 312. It should be noted that in this embodiment, one of the two air supply ports 314 is an intake port and the other is an exhaust port.
