In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0042] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0043] The present invention relates to a battery restraint machine, which includes a tray 1000 and a restraint and pressurizing device 2000. Battery cells can be placed in the tray 1000. Under the action of the restraint and pressurizing device 2000, the tray 1000 can restrain and pressurize the battery cells to achieve pressurization and pressure maintenance of the battery cells. Afterwards, the tray 1000 can be sent to a formation cabinet to complete formation and capacity formation.

[0044] Tray 1000 includes a restraint assembly and a restraint and pressure component 1101. The restraint and pressure device 2000 includes a push-and-press assembly, which includes a push-and-press component 2102. Specifically, a battery cell can be placed in the restraint assembly. Under the action of push-and-press component 2102, restraint and pressure component 1101 can apply pressure to the ends of the restraint assembly, thereby pressurizing the battery cell.

[0045] Tray 1000 includes a restraining and pressure-maintaining component 1301, and the restraining and pressurizing device 2000 includes a pushing and pressure-maintaining assembly, which includes a pushing and pressure-maintaining component 2202. Specifically, after restraining and pressurizing component 1101 presses against the restraining assembly, the pushing and pressure-maintaining component 2202 acts to push restraining and pressure-maintaining component 1301 against restraining and pressurizing component 1101, thereby maintaining the pressure on the battery cells.

[0046] In order to improve the degree of automation and production efficiency of the equipment, the battery restraint machine includes a conveying device, which can transport the tray 1000 to the restraint and pressurizing device 2000. After the tray 1000 is moved into place, the restraint and pressurizing device 2000 is started and can apply a restraining and compacting force to the battery cells in the tray 1000. After the restraint and compaction are completed, the conveying device will send the tray 1000 out.

[0047] Specifically, the conveying device includes a plurality of conveying rollers 3001, each of which is capable of rotating. Referring to the accompanying drawings, the conveying device includes a conveying frame, with both ends of the conveying rollers 3001 hinged to the conveying frame. Furthermore, the conveying device includes a transmission chain and a conveying drive. The conveying drive is configured as a motor connected to the conveying frame, and the conveying drive drives the conveying rollers 3001 to rotate via the transmission chain.

[0048] Furthermore, the battery restraint machine includes a lifting device, which includes a liftable lifting component 4001. The lifting component 4001 is configured as a support column. With reference to the accompanying drawings, multiple lifting components 4001 are provided in the gap between two adjacent conveyor rollers 3001 in the conveying device near the restraint and pressure device 2000. It is understandable that when the tray 1000 is conveyed to the restraint and pressure device 2000, the lifting component 4001 can extend from the support surface of the conveying device to prop up the tray 1000 so that the restraint and pressure device 2000 can complete the restraint and compression of the battery cells in the tray 1000.

[0049] Specifically, the lifting device includes a lifting driver 4002 and a lifting movable plate. The lifting movable plate is disposed below the support surface of the conveying device. The lifting component 4001 is disposed on the lifting movable plate. The lifting driver 4002 is capable of driving the lifting movable plate to move upward and downward, thereby moving the lifting component 4001 upward and downward. In some examples, the lifting driver 4002 is configured as a cylinder.

[0050] The structure of the tray 1000 will be described below.

[0051] Tray 1000 includes a tray body, which includes a tray base and multiple side panels. A restraint assembly is disposed within the tray body, and a restraint pressure member 1101 is disposed within the tray body. Referring to the accompanying drawings, restraint pressure member 1101 is configured as a pressure plate. Specifically, restraint pressure member 1101 is disposed within the tray body near the first end of the tray body.

[0052] During the tightening process, the restraint pressure member 1101 can move, specifically, toward the restraint assembly so that the restraint pressure member 1101 can apply pressure to the first end of the restraint assembly. In this case, the side plate at the second end of the disc body can abut against the second end of the restraint assembly.

[0053] It is understood that at least one restraint assembly is provided. In some examples, a plurality of restraint assemblies are provided to increase the capacity of the tray 1000. Specifically, in the tray 1000, the restraint assemblies are provided in parallel.

[0054] With reference to the accompanying drawings, the restraint assembly has multiple restraint stations 1201, where battery cells can be placed. Specifically, the restraint assembly includes multiple shaping components 1202, each of which is arranged in a row, with the area between two adjacent shaping components 1202 serving as the restraint station 1201. It will be understood that when the restraint pressure component 1101 applies pressure to the end of the restraint assembly, the shaping components 1202 can restrain and compress the battery cells.

[0055] With reference to the accompanying drawings, the side panel at the first end of the disc body is provided with a restraint and pressure escape area 1102, which extends through the side panel at the first end of the disc body. It is understood that the propulsion and pressure component 2102 of the restraint and pressure device 2000 can pass through the restraint and pressure escape area 1102 and press against the restraint and pressure component 1101. Under the push of the propulsion and pressure component 2102, the restraint and pressure component 1101 can move and compress the restraint assembly.

[0056] In order to enable the propulsion pressure component 2102 to smoothly push the restraint pressure component 1101, at least two propulsion pressure components 2102 are set corresponding to one restraint pressure component 1101. Accordingly, the side panel has at least two restraint pressure avoidance areas 1102 corresponding to one restraint pressure component 1101.

[0057] The tray 1000 includes a restraining and pressurizing guide member 1400, which is configured as a guide rod and is connected to the tray body. The restraining and pressurizing member 1101 is movably connected to the restraining and pressurizing guide member 1400. It is understood that during the restraining and pressing process, the restraining and pressurizing guide member 1400 can provide guidance for the movement of the restraining and pressurizing member 1101. Specifically, the restraining and pressurizing guide member 1400 penetrates the restraining and pressurizing member 1101, and the restraining and pressurizing member 1101 is pressurized and can move along the restraining and pressurizing guide member 1400.

[0058] The restraint pressure component 1101 can be provided in one or more forms, as follows: In some examples, the restraint pressure component 1101 is provided in a one-to-one correspondence with each restraint assembly, i.e., one restraint pressure component 1101 is provided at the first end of the restraint assembly, and the number of restraint pressure components 1101 is the same as the number of restraint assemblies. In some examples, when there are multiple restraint assemblies, the restraint pressure component 1101 is provided as a larger pressure plate, so that the restraint pressure component 1101 can simultaneously push each restraint assembly.

[0059] During the restraint and compression process, the restraint and pressure guide component 1400 can provide guidance for the movement of the shaping component 1202. Specifically, the restraint assembly includes multiple shaping connection components 1203, which are movably connected to the restraint and pressure guide component 1400, and the shaping component 1202 is mounted on the shaping connection components 1203. With reference to the accompanying drawings, the shaping connection components 1203 are arranged in pairs, with the two ends of the shaping component 1202 respectively mounted on the shaping connection components 1203. The restraint and pressure guide component 1400 extends through each shaping connection component 1203 located on the same side, and the shaping connection components 1203 can move along the restraint and pressure guide component 1400.

[0060] Considering the different sizes of battery cells encountered in actual production, and to improve the adaptability of tray 1000, the shaping member 1202 is designed to be removable. This allows tray 1000 to be replaced with shaping members 1202 of different sizes to adjust the size of restraint station 1201, thereby accommodating battery cells of various sizes. It is understood that both ends of shaping member 1202 are detachably connected to shaping connection members 1203.

[0061] With reference to the accompanying drawings, the shaped connecting member 1203 is provided with a shaped connecting slot, one end of which extends toward the surface of the tray 1000. The shaped connecting slot is open on the upper surface of the shaped connecting member 1203 along the extension direction. The end of the shaped member 1202 is provided with a shaped connecting protrusion, which can be inserted into the shaped connecting slot to assemble the shaped member 1202 with the shaped connecting member 1203. It is understood that the shaped connecting protrusion can be removed from the shaped connecting slot to separate the shaped member 1202 from the shaped connecting member 1203.

[0062] Regarding the structure of the shaping component 1202, specifically, it includes a shaping partition and a shaping end plate. Referring to the accompanying drawings, a shaping end plate is provided at each end of the shaping partition, with the shaping end plate located partially on one side of the shaping partition and partially on the other side. Referring to the accompanying drawings, the area enclosed by each shaping partition and each shaping end plate between two adjacent shaping components 1202 forms a restraint station 1201. By designing shaping partitions and shaping end plates of varying thicknesses, restraint stations 1201 of varying sizes can be obtained. It is understood that the shaping component 1202 located at the end of the restraint assembly and the shaping end plate are located on one side of the shaping partition.

[0063] Of course, as an alternative, it can also be designed as follows: the shaping component 1202 is set as a shaping partition, and the area between two adjacent shaping partitions forms the restraint station 1201.

[0064] Furthermore, considering that the battery cells generate heat during formation and conversion in the forming cabinet, a heat dissipation structure is provided on the forming component 1202 to facilitate heat dissipation. Specifically, a plurality of heat dissipation holes or a plurality of heat dissipation slots are provided in the forming partition, and a plurality of heat dissipation holes or a plurality of heat dissipation slots are provided on the forming end plate, thereby increasing the heat dissipation area.

[0065] When the restraint pressure component 1101 presses against the restraint assembly, the restraint pressure-maintaining component 1301 needs to press against the restraint pressure component 1101 to maintain the pressure against the restraint assembly. Referring to the accompanying drawings, the restraint pressure-maintaining component 1301 extends through a side panel of the disk body, with the first end of the restraint pressure-maintaining component 1301 extending into the disk body. It is understood that the first end of the restraint pressure-maintaining component 1301 can move to a position that presses against the restraint pressure component 1101.

[0066] In some examples, the restraining and pressure-maintaining component 1301 is threadedly connected to the disk body. Specifically, the restraining and pressure-maintaining component 1301 is threadedly connected to the side plate of the disk body. It is understood that the side plate at the first end of the disk body is provided with a threaded hole. In this case, on the one hand, rotating the restraining and pressure-maintaining component 1301 can achieve movement of the restraining and pressure-maintaining component 1301; on the other hand, the threads can fix the restraining and pressure-maintaining component 1301, providing a stop and prevent it from moving.

[0067] Specifically, the restraining and pressure-maintaining component 1301 is provided with a restraining and pressure-maintaining engaging portion, and applying force to the restraining and pressure-maintaining engaging portion enables the restraining and pressure-maintaining component 1301 to rotate. In some examples, the restraining and pressure-maintaining engaging portion is provided at the second end of the restraining and pressure-maintaining component 1301, and the advancing and pressure-maintaining component 2202 can be transmission-connected to the restraining and pressure-maintaining engaging portion, so that the advancing and pressure-maintaining component 2202 can drive the restraining and pressure-maintaining component 1301 to rotate.

[0068] In some examples, a pressure-retaining bearing seat 1500 is provided on the side of the restraining and pressurizing component 1101, and the first end of the restraining and pressure-retaining component 1301 can abut against the pressure-retaining bearing seat 1500. Specifically, the pressure-retaining bearing seat 1500 has a limiting area, and the first end of the restraining and pressure-retaining component 1301 can be inserted into the limiting area, which can prevent the restraining and pressure-retaining component 1301 from shifting. In conjunction with the accompanying drawings, the pressure-retaining bearing seat 1500 is provided with two pressure-retaining side stops 1501, which are arranged opposite each other, and the area between the two pressure-retaining side stops 1501 is the limiting area.

Specifically, the pushing and pressuring assembly includes a pushing and pressuring driver 2101, which can drive the pushing and pressuring component 2102 to move linearly. The pushing and pressuring component 2102 can extend into the tray 1000 so that the pushing and pressuring component 2102 can push the restraining and pressuring component 1101. With reference to the accompanying drawings, the restraining and pressuring device 2000 includes a restraining and pressuring base 2401, which is connected to the conveyor frame, the pushing and pressuring driver 2101 is connected to the restraining and pressuring base 2401, and the pushing and pressuring component 2102 is configured as a push rod.

[0071] The propulsion and pressurization assembly includes a propulsion and pressurization transmission assembly, and the propulsion and pressurization driver 2101 drives the propulsion and pressurization component 2102 to move linearly through the propulsion and pressurization transmission assembly. In some examples, the propulsion and pressurization transmission assembly includes a pressurization transmission rod 2104 and a propulsion and pressurization moving member 2105. The output end of the propulsion and pressurization driver 2101 is connected to the first end of the pressurization transmission rod 2104, and the pressurization transmission rod 2104 passes through the propulsion and pressurization moving member 2105. Under the action of the pressurization transmission rod 2104, the propulsion and pressurization moving member 2105 can move, and the propulsion and pressurization component 2102 is connected to the propulsion and pressurization moving member 2105.

[0072] Specifically, the push-and-press driver 2101 is configured as a motor. The push-and-press driver 2101 is capable of driving the pressurizing transmission rod 2104 to rotate. The pressurizing transmission rod 2104 drives the push-and-press moving member 2105 to move via a threaded transmission, thereby driving the push-and-press moving member 2105 to move the push-and-press component 2102. Referring to the accompanying drawings, the restraint and pressurizing device 2000 includes a push-and-press support seat 2402, which is connected to the restraint and pressurizing base 2401. The second end of the pressurizing transmission rod 2104 is hingedly connected to the push-and-press support seat 2402.

[0073] In order to enable the propulsion and pressure component 2102 to move smoothly, the propulsion and pressure component 2102 passes through the propulsion support seat 2402 . It can be understood that the propulsion support seat 2402 can support the propulsion and pressure component 2102 .

[0074] In conjunction with the accompanying drawings, the restraint and pressurization device 2000 includes a propulsion and pressurization guide component 2103, which is connected to the restraint and pressurization base 2401, and a propulsion and pressurization movable member 2105 is movably connected to the propulsion and pressurization guide component 2103.

[0075] Specifically, the push-pushing guide member 2103 is configured as a guide rail, and the push-pushing movable member 2105 is movably connected to the push-pushing guide member 2103 via a slider. In conjunction with the accompanying drawings, two push-pushing guide members 2103 are provided. Of course, it is understood that the push-pushing guide member 2103 can also be replaced with a guide rod that penetrates the push-pushing movable member 2105.

[0076] Regarding the transmission between the propulsion and pressure driver 2101 and the propulsion and pressure component 2102, as an alternative, the propulsion and pressure driver 2101 can also be designed as a cylinder, and the propulsion and pressure component 2102 is connected to the output end of the propulsion and pressure driver 2101.

[0077] The propulsion and pressure-maintaining assembly includes a propulsion and pressure-maintaining driver 2201, which is connected to the restraint and pressure-maintaining base 2401. The propulsion and pressure-maintaining component 2202 is connected to the output end of the propulsion and pressure-maintaining driver 2201. With reference to the accompanying drawings, the propulsion and pressure-maintaining component 2202 passes through the propulsion support seat 2402, which supports the propulsion and pressure-maintaining component 2202. Specifically, the propulsion and pressure-maintaining driver 2201 is configured as a motor, which can drive the propulsion and pressure-maintaining component 2202 to rotate. The propulsion and pressure-maintaining component 2202 is in transmission connection with the restraint and pressure-maintaining component 1301, thereby driving the restraint and pressure-maintaining component 1301 to rotate.

[0078] The advancing and pressure-maintaining component 2202 is provided with an advancing and pressure-maintaining engaging portion, which is disposed at one end of the advancing and pressure-maintaining component 2202 and is capable of connecting with the restraining and pressure-maintaining engaging portion of the restraining and pressure-maintaining component 1301.

[0080] The advancing and pressure-maintaining clamping portion includes an advancing and pressure-maintaining sleeve portion 2203, which can be sleeved on one end of the restraining and pressure-maintaining component 1301. Referring to the accompanying drawings, the advancing and pressure-maintaining clamping structure is configured as a notch 2204 at the end of the advancing and pressure-maintaining sleeve portion 2203. The notch 2204 is provided at the end of the side wall of the advancing and pressure-maintaining sleeve portion 2203. Specifically, the notch 2204 can be connected to the restraining and pressure-maintaining clamping structure 1302. When the advancing and pressure-maintaining actuator 2201 drives the advancing and pressure-maintaining component 2202 to rotate, the notch 2204 and the restraining and pressure-maintaining clamping structure 1302 are locked, thereby enabling the advancing and pressure-maintaining actuator 2201 to drive the restraining and pressure-maintaining component 1301 to rotate, thereby achieving movement of the restraining and pressure-maintaining component 1301.

[0081] With reference to the accompanying drawings, the opening direction of the recess 2204 is inclined relative to the axial direction of the advancing and pressure-maintaining component 2202. After the advancing and pressure-maintaining sleeve 2203 is sleeved onto the end of the restraining and pressure-maintaining component 1301, the advancing and pressure-maintaining driver 2201 drives the advancing and pressure-maintaining component 2202 to rotate, thereby connecting the recess 2204 to the restraining and pressure-maintaining retaining structure 1302. In this case, when the advancing and pressure-maintaining component 2202 is turned over, the recess 2204 is separated from the restraining and pressure-maintaining retaining structure 1302.

[0082] Of course, as an alternative, the opening direction of the recess 2204 can also be designed to be arranged along the axial direction of the pushing and pressure maintaining component 2202. In this case, when the pushing and pressure maintaining component 2202 retreats, the recess 2204 is separated from the restraining and pressure maintaining fixing structure 1302.

[0083] Regarding the advancing and pressure-maintaining clamping portion and the restraining and pressure-maintaining clamping portion, alternative designs are also possible: in some examples, the advancing and pressure-maintaining clamping portion is configured as a regular polygonal connecting end at one end of the advancing and pressure-maintaining component 2202, and correspondingly, the restraining and pressure-maintaining clamping portion is configured as a countersunk hole at the end of the restraining and pressure-maintaining component 1301, the countersunk hole being configured as a regular polygon, and the connecting end and the countersunk hole being able to be plugged in and locked. In some examples, the advancing and pressure-maintaining clamping portion is configured as a regular polygonal countersunk hole at one end of the advancing and pressure-maintaining component 2202, and correspondingly, the restraining and pressure-maintaining clamping portion is configured as a regular polygonal connecting end at the end of the restraining and pressure-maintaining component 1301.

[0084] During the rotation process, the propulsion and pressure-maintaining component 2202 can move toward the tray 1000 to maintain the transmission connection between the propulsion and pressure-maintaining component 2202 and the restraint and pressure-maintaining component 1301. It is understood that the propulsion and pressure-maintaining driver 2201 can move on the restraint and pressure base 2401 to enable the propulsion and pressure-maintaining component 2202 to move.

[0085] Specifically, the advancing and pressure-maintaining assembly includes a synchronous advancing driver 2205, which is connected to the restraining and pressurizing base 2401. It is understood that when the advancing and pressure-maintaining driver 2201 drives the advancing and pressure-maintaining component 2202 to rotate, the synchronous advancing driver 2205 can drive the advancing and pressure-maintaining driver 2201 to move toward the tray 1000, and the advancing and pressure-maintaining component 2202 connected to the advancing and pressure-maintaining driver 2201 moves accordingly.

[0086] It will be appreciated that the restraint and pressurizing device 2000 includes a synchronous propulsion guide component disposed on the restraint and pressurizing base 2401. The synchronous propulsion driver 2205 drives the propulsion and pressure-maintaining driver 2201 to move along the synchronous propulsion guide component. Specifically, the synchronous propulsion guide component is configured as a guide rail, and the propulsion and pressure-maintaining driver 2201 is movably connected to the synchronous propulsion guide component via a slider. With reference to the accompanying drawings, one propulsion and pressure-maintaining driver 2201 is configured with two synchronous propulsion guide components.

[0087] To stabilize the position of the tray 1000 during the restraint and pressurization process, the battery restraint machine is equipped with a restraint and pressurization support seat 2403. When the restraint and pressurization device 2000 applies force to the restraint and pressurization component 1101 at the first end of the tray 1000, the restraint and pressurization support seat 2403 can abut the second end of the tray 1000. With reference to the accompanying drawings, the restraint and pressurization support seat 2403 and the restraint and pressurization device 2000 are located on either side of the conveyor device, and the restraint and pressurization support seat 2403 and the restraint and pressurization device 2000 are in opposing positions. The conveyor device can convey the tray 1000 between the restraint and pressurization support seat 2403 and the restraint and pressurization device 2000. Specifically, the restraint and pressurization support seat 2403 is connected to the conveyor frame.

[0088] In conjunction with the accompanying drawings, the restraint and pressure-maintaining device 2000 includes an auxiliary pressure-maintaining component 2300, which is connected to the restraint and pressure-maintaining base 2401. The auxiliary pressure-maintaining component 2300 includes an auxiliary pressure-maintaining part 2301. After the pushing pressure part 2102 pushes the restraint and pressure-maintaining part 1101 in the tray 1000 into place, before the pushing pressure-maintaining part 2202 has not yet abutted against the restraint and pressure-maintaining part 1301, the auxiliary pressure-maintaining part 2301 can move to a position abutting against the restraint and pressure-maintaining part 1101, so that the restraint and pressure-maintaining part 1101 remains in a compressed state.

[0089] Specifically, the auxiliary pressure-maintaining assembly 2300 includes an auxiliary pressure-maintaining propulsion assembly and an auxiliary pressure-maintaining lifting assembly. The auxiliary pressure-maintaining propulsion assembly is connected to the restraint and pressurization base 2401. The auxiliary pressure-maintaining propulsion assembly can drive the auxiliary pressure-maintaining lifting assembly to move toward the tray 1000, and the auxiliary pressure-maintaining lifting assembly can drive the auxiliary pressure-maintaining component 2301 to move up and down. It is understood that during the descent of the auxiliary pressure-maintaining component 2301, it can be inserted into the tray 1000 from above, pressing against the restraint and pressurization component 1101. After the pressure-maintaining component 2202 moves into place, the auxiliary pressure-maintaining component 2301 rises and leaves the tray 1000, facilitating the separation of the tray 1000 from the restraint and pressurization device 2000.

[0090] The auxiliary pressure-maintaining propulsion assembly includes an auxiliary pressure-maintaining propulsion driver 2311 and an auxiliary pressure-maintaining propulsion seat 2312. The auxiliary pressure-maintaining propulsion driver 2311 drives the auxiliary pressure-maintaining propulsion seat 2312 to move in a pneumatic or screw-type manner, and the auxiliary pressure-maintaining lifting assembly is connected to the auxiliary pressure-maintaining propulsion seat 2312.

[0091] Furthermore, the auxiliary pressure-maintaining propulsion assembly includes an auxiliary pressure-maintaining propulsion guide component, which is arranged along the direction of pressurization. The auxiliary pressure-maintaining propulsion guide component is arranged as a guide rail, and the auxiliary pressure-maintaining propulsion seat 2312 moves along the auxiliary pressure-maintaining propulsion guide component through a slider.

[0092] The auxiliary pressure-maintaining lifting assembly includes an auxiliary pressure-maintaining lifting driver 2321 and an auxiliary pressure-maintaining lifting seat 2322. The auxiliary pressure-maintaining lifting driver 2321 drives the auxiliary pressure-maintaining lifting seat 2322 to move in a pneumatic or screw-type manner. The auxiliary pressure-maintaining component 2301 is connected to the auxiliary pressure-maintaining lifting seat 2322.

[0093] Specifically, in order to save time and improve production efficiency, the auxiliary pressure-maintaining lifting driver 2321 is designed to be a pneumatic device. Compared with the driving method of the threaded transmission of the propulsion pressurizing component, the auxiliary pressure-maintaining lifting driver 2321 adopts a pneumatic method and can move faster. Therefore, after the pressurization is completed and before the pressure maintenance begins, the auxiliary pressure-maintaining component 2301 is against the restraint pressurizing component 1101. While the restraint pressure-maintaining component 1301 moves to maintain pressure, the propulsion pressurizing component 2102 can retreat.

[0094] Furthermore, the auxiliary pressure-maintaining lifting assembly includes an auxiliary pressure-maintaining lifting guide component, which is configured as a guide rail, and the auxiliary pressure-maintaining lifting seat 2322 moves along the auxiliary pressure-maintaining lifting guide component via a slider.

[0095] The following describes the process of restraining and compacting the battery cells in the tray 1000 in conjunction with the structure of the battery restraint machine. It should be noted that the following description is merely an example and does not constitute a specific limitation to the invention.

[0096] The conveying device transports the tray 1000 to the restraint and pressurizing device 2000, and the push-pressurizing driver 2101 is started, driving the push-pressurizing movable part 2105 in a screw transmission manner. The push-pressurizing movable part 2105 drives the push-pressurizing component 2102 to extend into the tray 1000 and push the restraint and pressurizing component 1101 to press the battery cell.

[0097] The auxiliary pressure-maintaining propulsion assembly is started to move the auxiliary pressure-maintaining lifting assembly provided with the auxiliary pressure-maintaining component 2301 toward the direction close to the tray 1000, and the auxiliary pressure-maintaining lifting assembly is started to lower the auxiliary pressure-maintaining component 2301 to a position where it can resist the restraint pressure component 1101.

[0098] The propulsion and pressure-maintaining assembly is started, and the propulsion and pressure-maintaining driver 2201 drives the restraint and pressure-maintaining component 1301 to rotate through the propulsion and pressure-maintaining component 2202. At the same time, the synchronous propulsion driver 2205 is started. When the restraint and pressure-maintaining component 1301 moves, the propulsion and pressure-maintaining driver 2201 moves synchronously in the same direction.

[0099] After the restraining pressure-maintaining component 1301 moves to the pressure-maintaining position, the auxiliary pressure-maintaining component 2301 and the pushing pressure-maintaining component 2202 withdraw from the tray 1000, and the conveying device sends the tray 1000 out.

[0100] It is understandable that after the auxiliary pressure-maintaining component 2301 is lowered into place, when the pressure-maintaining assembly is pushed in operation, the pressure-applying component 2102 can be synchronously withdrawn from the tray 1000, saving time and improving efficiency.
