[0001] This application relates to the field of battery manufacturing technology, and in particular to a continuous isostatic feeding device and production system for all-solid-state batteries. Background Technology

[0002] The fabrication of all-solid-state batteries often involves isostatic pressing. Isostatic pressing of all-solid-state batteries uses uniform high-pressure densification technology to address challenges such as interface contact and energy density, thereby improving overall performance. Current technologies for all-solid-state batteries utilize cell loading and unloading devices to automate the loading and unloading of cells within the isostatic pressing apparatus, improving efficiency. However, these devices are only suitable for vertical isostatic pressing apparatuses, where cells are loaded and unloaded vertically, and are insufficient for horizontal isostatic pressing apparatuses. Utility Model Content

[0003] Based on this, this application provides a continuous isostatic pressing feeding device and production system for all-solid-state batteries, in order to improve the problem that the existing cell loading and unloading devices cannot meet the loading and unloading requirements of horizontal isostatic pressing devices.

[0004] In a first aspect, this application provides a continuous isostatic pressing (OSP) feeding device for all-solid-state batteries, the OSP feeding device comprising: A feed pusher is used to abut against a material cylinder, which is used to arrange battery cells; A drive mechanism is connected to the feed push rod and is used to drive the feed push rod to move horizontally and drive the material cylinder to move synchronously in the horizontal direction.

[0012] In one embodiment, the isostatic pressing device includes an isostatic pressing cylinder and a traversing mechanism. The isostatic pressing cylinder is connected to the traversing mechanism, which drives the isostatic pressing cylinder to move between a first working position and a second working position. The all-solid-state battery continuous isostatic pressing feeding device is used to feed the battery cell into the isostatic pressing cylinder or unload the battery cell from the isostatic pressing cylinder when the isostatic pressing cylinder is in the first working position.

[0013] In one embodiment, the all-solid-state battery continuous isostatic pressing production system further includes: A material cylinder transfer device, used to transfer the material cylinder; A fixture transfer device is used to transfer the fixtures for clamping battery cells.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0018] It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model.

[0019] The structures, proportions, sizes, etc., shown in the accompanying drawings of this specification are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which this utility model can be implemented. Any modifications to the structure, changes in the proportions, or adjustments to the size, without affecting the effects and purposes that this utility model can produce, should still fall within the scope of the technical content disclosed in this utility model.

[0020] The orientations or positional relationships indicated by terms such as "upper," "lower," "left," "right," "middle," "longitudinal," "transverse," "horizontal," "inner," "outer," "radial," and "circumferential" used in this specification are based on the orientations or positional relationships shown in the accompanying drawings and are only for the purpose of simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] As described in the background art, when all-solid-state battery cells undergo isostatic pressing, they can be automatically loaded and unloaded within the isostatic pressing device using a cell loading and unloading device, thereby improving the efficiency of the isostatic pressing process. In the prior art, the cell loading and unloading device may include a moving component and a connecting component, wherein the connecting component is connected to the moving component, and the moving component is used to drive the connecting component to move. The moving component may include two mutually perpendicular linear modules, which are used to realize the vertical and horizontal movement of the connecting component, respectively. The connecting component is used to detachably connect to the material frame on which the cells are arranged, and its connection position with the material frame is usually located at the top of the material frame. During feeding, the connecting component moves closer to the connecting component under the drive of the moving component and then connects with the material frame; then it moves closer to the isostatic pressing device under the drive of the moving component again. Since the isostatic pressing device is a vertical isostatic pressing device, the moving component loads the material frame from top to bottom into the isostatic pressing device through the connecting component, and removes the material frame from the isostatic pressing device from bottom to top when isostatic pressing is completed.

[0022] However, when this cell loading device is applied to a horizontal isostatic pressing unit, its connecting parts should be connected to one end of the material frame in the horizontal direction. During loading, the center of gravity of the material frame is prone to shift in the horizontal direction, causing the material frame to tilt. When the material frame enters the isostatic pressing unit, there is a risk of collision between the material frame and the isostatic pressing unit, which could damage the material frame, the cell, or the isostatic pressing unit. Therefore, it is easy to see that the existing cell loading and unloading devices are insufficient to meet the loading and unloading requirements of horizontal isostatic pressing units.

[0023] Based on this, embodiments of this application provide a continuous isostatic pressing feeding device 100 for all-solid-state batteries, such as... Figures 1 to 3 As shown, the all-solid-state battery continuous isostatic pressing feeding device 100 includes: The feed pusher 110 is used to abut against the material cylinder 200, which is used to arrange the battery cells; The drive mechanism 120 is connected to the feed push rod 110 and is used to drive the feed push rod 110 to move horizontally and drive the material cylinder 200 to move synchronously in the horizontal direction.

[0024] like Figure 1 and Figure 2 As shown in this embodiment, by way of example, the all-solid-state battery continuous isostatic pressing feeding device 100 can be used to feed the material cylinder 200 into the horizontal isostatic pressing device 300. It can include a feeding push rod 110 for abutting against the material cylinder 200 and a drive mechanism 120 connected to the feeding push rod 110 and used to drive the feeding push rod 110 to move in the horizontal direction. When the drive mechanism 120 drives the feeding push rod 110 to move, the feeding push rod 110 can abut against one end of the material cylinder 200 and can push the material cylinder 200 to move synchronously in the horizontal direction.

[0025] The horizontal isostatic pressing device 300 may include an isostatic pressing cylinder 310 arranged in a horizontal direction. The isostatic pressing cylinder 310 may have a first working position and a second working position. The first working position may be a feeding working position, i.e., a working position for feeding the material cylinder 200; and the second working position may be an isostatic pressing working position, i.e., a working position for performing isostatic pressing treatment on the battery cell. When the isostatic pressing cylinder 310 is in the first working position, it can be coaxially arranged with the material cylinder 200. At this time, the feed pusher 110 drives the material cylinder 200 to move synchronously in the horizontal direction to feed the material cylinder 200 into the isostatic pressing cylinder 310. After feeding is completed, the isostatic pressing cylinder 310 can move to the second working position to perform isostatic pressing treatment on the battery cell.

[0026] like Figure 2 As shown, when the isostatic pressing of the battery cell is completed, the isostatic pressing cylinder 310 can be reset to the first working position. At this time, the feed pusher 110 can drive the next material cylinder 200 to move synchronously in the horizontal direction, so as to feed the next material cylinder 200 into the isostatic pressing cylinder 310. During the process of the next material cylinder 200 entering the isostatic pressing cylinder 310, the next material cylinder 200 can squeeze the material cylinder 200 that has completed the isostatic pressing process out of the isostatic pressing cylinder 310, thereby realizing the unloading of the material cylinder 200 within the isostatic pressing cylinder 310. When the last material cylinder 200 that has completed the isostatic pressing process needs to be unloaded, an empty material cylinder 200 can be fed into the isostatic pressing cylinder 310, so as to squeeze the last material cylinder 200 that has completed the isostatic pressing process out of the isostatic pressing cylinder 310.

[0027] It is understood that the all-solid-state battery continuous isostatic pressing feeding device 100 provided in this application drives the feeding push rod 110 to move horizontally through the driving mechanism 120. This allows the feeding push rod 110 to drive the material cylinder 200 to move synchronously in the horizontal direction after it comes into contact with the material cylinder 200, so as to realize the feeding or unloading of the material cylinder 200 in the horizontal isostatic pressing device 300. This improves the problem that the existing battery cell loading and unloading devices cannot meet the feeding and unloading requirements of the horizontal isostatic pressing device 300.

[0028] Specifically, the drive mechanism 120 includes a drive motor 121 and a synchronous belt assembly 122. The synchronous belt assembly 122 includes a drive pulley 1221 and a synchronous belt 1222. The drive motor 121 drives the drive pulley 1221 and causes the drive pulley 1221 to rotate. The synchronous belt 1222 is disposed on the drive pulley 1221, and the feed push rod 110 is disposed on the synchronous belt 1222.

[0029] like Figure 1 As shown in this embodiment, the drive mechanism 120 may include a drive motor 121 serving as a power source and a synchronous belt assembly 122 connecting the drive motor 121 and the feed push rod 110. The synchronous belt assembly 122 may include a frame 1224, a drive pulley 1221, a driven pulley 1223, and a synchronous belt 1222. The drive pulley 1221 and the driven pulley 1223 may both be rotatably mounted on the frame 1224 and may be coaxially mounted at both ends of the frame 1224. The drive pulley 1221 may be tensioned on the drive pulley 1221 and the driven pulley 1223. When the drive pulley 1221 rotates, it can drive the driven pulley 1223 to rotate synchronously through the synchronous belt 1222, and the synchronous belt 1222 may perform a rotary motion. The driving pulley 1221 may include a drive shaft, which can drive the drive motor 121, for example, through a coupling, so that the drive motor 121 can drive the driving pulley 1221 to rotate. Both ends of the drive shaft can also be connected to bearing housings to improve the smoothness of the rotation of the driving pulley 1221. The axle of the driven pulley 1223 can be arranged similarly. The feed pusher 110 can be located above the synchronous belt 1222. When the synchronous belt 1222 rotates, it can drive the feed pusher 110 to move synchronously, so that the feed pusher 110 abuts against the material cylinder 200 and drives the material cylinder 200 to move synchronously in the horizontal direction.

[0030] It is understood that in this embodiment, by setting the drive mechanism 120 to at least a drive mechanism 120 and a timing belt assembly 122, and setting the timing belt assembly 122 to at least a drive pulley 1221 and a timing belt 1222, the drive mechanism 120 can drive the feed push rod 110 to move horizontally and drive the material cylinder 200 to move synchronously horizontally.

[0031] More specifically, the feed pusher 110 includes a pusher base 111, a pusher body 112, and a pusher disc 113. The pusher body 112 is disposed between the pusher base 111 and the pusher disc 113. The pusher base 111 is disposed on the timing belt 1222, and the pusher disc 113 is used to abut against the feed cylinder 200.

[0032] like Figure 1As shown in this embodiment, the feed pusher 110 may include a pusher base 111, a pusher body 112, and a pusher disc 113. The pusher body 112 may be rod-shaped and horizontally oriented. One end of the pusher body 112 may be connected to the pusher base 111, which may be cuboid and positioned above the synchronous belt 1222. The other end of the pusher body 112 may be connected to the pusher disc 113, which may be disc-shaped and coaxially aligned with the pusher body 112. The disc-shaped pusher disc 113 abuts against one end of the feed cylinder 200, increasing the contact area between the pusher body 112 and the feed cylinder 200 to achieve an effective contact. When the synchronous belt 1222 rotates, it can drive the material cylinder 200 to move synchronously through the push rod base 111, the push rod body 112 and the push rod disc 113 in sequence.

[0033] It is understood that in this embodiment, by configuring the feed pusher 110 as at least a pusher base 111, a pusher body 112, and a pusher disc 113, the timing belt 1222 can drive the material cylinder 200 to move smoothly and synchronously through the feed pusher 110.

[0034] Specifically, the material cylinder 200 is cylindrical, and the axis of the material cylinder 200 is set in the horizontal direction. The drive mechanism 120 also includes a bearing wheel assembly 123, which is set in two sets. The material cylinder 200 is slidably mounted on the two sets of bearing wheel assemblies 123.

[0035] like Figure 1 As shown in this embodiment, the feed cylinder 200 can be configured as a cylinder, with its axis arranged horizontally. The feed pusher 110 can abut against one end of the feed cylinder 200 along its axial direction, thereby driving the feed pusher 110 to move synchronously. The drive structure can also include a bearing wheel assembly 123, which can include a bearing plate 1231 and side wheels 1232. The bearing plate 1231 can be arranged along the extension direction of the synchronous belt 1222, and the side plate can be arranged on the bearing plate 1231. Several side wheels 1232 can be spaced apart along the extension direction of the bearing plate 1231, and their axes can be perpendicular to the extension direction of the bearing plate 1231 and inclined relative to the horizontal direction. The bearing wheel assembly 123 can be configured as two sets, and the two sets of bearing wheel assemblies 123 can be arranged on both sides of the width direction of the synchronous belt 1222. The material cylinder 200 can be arranged on two sets of bearing wheel assemblies 123, and the side wheels 1232 of the two sets of bearing wheel assemblies 123 can support the material cylinder 200. When the feed push rod 110 drives the material cylinder 200 to move synchronously in the horizontal direction, the material cylinder 200 can slide on the two sets of bearing wheel assemblies 123.

[0036] It is understood that in this embodiment, by setting the material cylinder 200 as a cylinder and setting its axis along the horizontal direction, and by arranging two sets of bearing wheel assemblies 123 to make the material cylinder 200 slidable, the bearing wheel assembly 123 can reduce the resistance encountered by the material cylinder 200 when it moves horizontally synchronously with the feed push rod 110, thereby ensuring the smoothness of the material cylinder 200 in the process of entering the isostatic pressing device 300.

[0037] Specifically, the barrel 200 is provided with an inner cavity 210, and the battery cells are arranged in the inner cavity 210 by the battery cell clamping fixture 400.

[0038] like Figure 1 and Figure 3 As shown in this embodiment, the barrel 200 may be provided with an inner cavity 210 for arranging battery cells. The inner cavity 210 may be rectangular, that is, the barrel 200 and its inner cavity 210 may adopt an "outer circle, inner square" design. The battery cells may be arranged in a battery cell clamping fixture 400, which may include several laminated plates. The battery cells may be clamped between two adjacent laminated plates, and the laminated plates may be locked and fixed by bolts and nuts. When the battery cell clamping is completed, the battery cell clamping fixture 400 can be arranged in the inner cavity 210 to realize the arrangement of the battery cells in the barrel 200.

[0039] It is understood that in this embodiment, by providing an inner cavity 210 on the barrel 200 and arranging the battery cell clamping fixture 400 with the battery cell in the inner cavity 210, it is convenient to arrange the battery cell in the barrel 200, thereby facilitating the feeding of the battery cell into the isostatic pressing device 300 for isostatic pressing treatment.

[0040] More specifically, the barrel 200 is provided with a feed inlet 220, and the battery cell clamping fixture 400 is arranged in the inner cavity 210 through the feed inlet 220.

[0041] like Figure 3 As shown in this embodiment, by way of example, the material cylinder 200 may be provided with a feed port 220, which may be formed by extending outward from the top of the inner cavity 210 through the material cylinder 200. Through the feed port 220, the cell clamping fixture 400 can be arranged in the inner cavity 210.

[0042] It is understood that this embodiment facilitates the arrangement of the battery cell clamping fixture 400 in the inner cavity 210 by providing the feed port 220.

[0043] More specifically, the barrel 200 is provided with a perforation 230 communicating with the inner cavity 210.

[0044] like Figure 3As shown in this embodiment, by way of example, the barrel 200 may also be provided with a perforation 230. The perforation 230 may be provided on the periphery of the barrel 200 and may extend from the inner cavity 210 to the outside of the barrel 200, that is, the perforation 230 is connected to the inner cavity 210. There may be several perforations 230, which may be evenly distributed, for example, in a rectangular array on the unfolded surface of the barrel 200. When the battery cell is arranged in the inner cavity 210 by the battery cell clamping fixture 400, and the barrel 200 is fed into the isostatic pressing device 300, the isostatic medium can also enter and exit the barrel 200 through the perforation 230 to ensure the effectiveness of the isostatic pressing treatment of the battery cell.

[0045] It is understood that by providing perforations 230 on the barrel 200 in this embodiment, the battery cell can be ensured to have full contact with the isostatic medium during isostatic pressing, thereby ensuring the isostatic pressing effect on the battery cell.

[0046] The implementation principle of the all-solid-state battery continuous isostatic feeding device 100 provided in this application embodiment is as follows: When the battery cell requires isostatic pressing, the battery cell is first clamped in the battery cell clamping fixture 400. Then, the battery cell clamping fixture 400 with the battery cell is placed in the inner cavity 210 of the material cylinder 200. The material cylinder 200 is then placed on two sets of bearing roller assemblies 123. The drive motor 121 drives the drive pulley 1221 to rotate, and the drive pulley 1221 can drive the driven pulley 1223 to rotate through the synchronous belt 1222. The synchronous belt 1222 can also rotate. When the upper side of the synchronous belt 1222 moves, it can drive the feed push rod 110 to move horizontally. Then, the feed push rod 110 can abut against one end of the material cylinder 200 and drive the material cylinder 200 to move synchronously horizontally, thereby feeding the material cylinder 200 into the isostatic pressing device 300. During the process of the next material cylinder 200 entering the isostatic pressing cylinder 310, the next material cylinder 200 can squeeze the material cylinder 200 that has completed the isostatic pressing process out of the isostatic pressing cylinder 310 to achieve material discharge.

[0047] The continuous isostatic pressing feeding device 100 for all-solid-state batteries provided in this application drives the feeding push rod 110 to move horizontally through the driving mechanism 120. After the feeding push rod 110 comes into contact with the material cylinder 200, it drives the material cylinder 200 to move synchronously in the horizontal direction, so as to realize the feeding or unloading of the material cylinder 200 in the horizontal isostatic pressing device 300. This improves the problem that the existing battery cell loading and unloading devices cannot meet the feeding and unloading requirements of the horizontal isostatic pressing device 300.

[0048] This application also provides a continuous isostatic pressing production system for all-solid-state batteries, such as... Figures 1 to 4 As shown, the continuous isostatic pressing production system for all-solid-state batteries includes: Isostatic pressing device 300, and; Any of the all-solid-state battery continuous isostatic pressing feeding devices 100 provided in this application are used to feed battery cells into the isostatic pressing device 300.

[0049] like Figure 4 As shown in this embodiment, the isostatic pressing device 300 can be a horizontal isostatic pressing device 300, and its feeding method can be feeding in a horizontal direction. In any of the all-solid-state battery continuous isostatic pressing feeding devices 100 provided in this application, the driving mechanism 120 can drive the feeding push rod 110 to move horizontally, so that after the feeding push rod 110 abuts against the material cylinder 200, it drives the material cylinder 200 to move synchronously in a horizontal direction, thereby feeding the material cylinder 200 into the isostatic pressing device 300.

[0050] Specifically, the isostatic pressing device 300 includes an isostatic pressing cylinder 310 and a transverse movement mechanism 320. The isostatic pressing cylinder 310 is connected to the transverse movement mechanism 320, which drives the isostatic pressing cylinder 310 to move between a first working position and a second working position. The all-solid-state battery continuous isostatic pressing feeding device 100 is used to feed the battery cells into the isostatic pressing cylinder 310 or unload the battery cells from the isostatic pressing cylinder 310 when the isostatic pressing cylinder 310 is in the first working position.

[0051] like Figure 2 As shown in this embodiment, the isostatic pressing device 300 may include an isostatic pressing cylinder 310 and a transverse movement mechanism 320. The isostatic pressing cylinder 310 may be a hollow cylinder structure with openings at both ends. The axis of the isostatic pressing cylinder 310 may be parallel to the direction in which the feed pusher 110 drives the material cylinder 200 to move synchronously. The isostatic pressing cylinder 310 may be mounted on the transverse movement mechanism 320, which may include a linear motion drive device such as a lead screw slide and a guide rail device for guidance. The transverse movement mechanism 320 can drive the isostatic pressing cylinder 310 to move, thereby enabling the isostatic pressing cylinder 310 to switch its working position. The direction of movement of the isostatic pressing cylinder 310 may be horizontal or perpendicular to its axis.

[0052] like Figure 2As shown, in this embodiment, the lateral movement mechanism 320 can drive the isostatic pressing cylinder 310 to move between a first working position and a second working position. The first working position can be the cell loading and unloading position. When the lateral movement mechanism 320 moves the isostatic pressing cylinder 310 to the first working position, the drive mechanism 120 of the all-solid-state battery continuous isostatic pressing feeding device 100 can drive the feeding push rod 110 to move horizontally, so that after the feeding push rod 110 abuts against the cylinder 200, it drives the cylinder 200 to move synchronously horizontally, thereby loading the cylinder 200 into the isostatic pressing cylinder 310. If a previous cylinder 200 is present in the isostatic pressing cylinder 310 at this time, the previous cylinder 200 can be unloaded from the isostatic pressing cylinder 310 under the abutment of the currently loading cylinder 200. The second working position can be the isostatic pressing position for the battery cell. In the second working position, the isostatic pressing cylinder 310 can be connected to the circulation system of the isostatic medium, so that the isostatic medium can enter the isostatic pressing cylinder 310. After the material cylinder 200 is fed into the isostatic pressing cylinder 310, the traversing mechanism 320 can drive the isostatic pressing cylinder 310 from the first working position to the second working position to realize the isostatic pressing treatment of the battery cell.

[0053] It is understood that in this embodiment, by configuring the isostatic pressing device 300 at least as an isostatic pressing cylinder 310 and a transverse moving mechanism 320, and by driving the isostatic pressing cylinder 310 to move between the first working position and the second working position through the transverse moving mechanism 320, it is convenient to realize the feeding and unloading of battery cells in the isostatic pressing device 300 and the isostatic pressing process.

[0054] More specifically, the continuous isostatic pressing production system for all-solid-state batteries also includes: The material cylinder transfer device 500 is used to transfer the material cylinder 200; The fixture transfer device 600 is used to transfer the battery cell clamping fixture 400. The automatic battery cell loading and unloading device 700 is used to load battery cells into the battery cell clamping fixture 400 or to remove battery cells from the battery cell clamping fixture 400. The fixture loading and unloading device 800 is located between the automatic battery cell loading and unloading device 700 and the material cylinder transfer device 500, and is used to assemble the battery cell clamping fixture 400 into the material cylinder 200 or to remove the battery cell clamping fixture 400 from the material cylinder 200.

[0055] like Figure 4As shown in this embodiment, the all-solid-state battery continuous isostatic pressing production system may further include a barrel transfer device 500, a fixture transfer device 600, an automatic cell loading and unloading device 700, and a fixture loading and unloading device 800. The barrel transfer device 500 can be configured as a rectangular rotary line, with one long side serving as the main line 510, primarily used for loading and unloading cells within the isostatic pressing device 300. The other long side and the two short sides serve as auxiliary lines, primarily used for the repeated transfer of empty barrels 200. The all-solid-state battery continuous isostatic pressing feeding device 100 can be located at one end of the main line 510 to feed the barrels 200 onto the main line 510, and its synchronous belt assembly 122 can be used as a component of the main line 510. When the isostatic pressing cylinder 310 moves to the first working position, it moves to the position of the main line body 510 so that the material cylinder 200 can enter the isostatic pressing cylinder 310. The main line body 510 is disconnected at the first working position of the isostatic pressing cylinder 310 to avoid interference with the isostatic pressing cylinder 310.

[0056] The fixture transfer device 600 can also be configured as a rotary line, which may include a double-layered line arranged vertically, extending in a straight line. The fixture transfer device 600 can be located on one side of the rotary line, close to the long side of the auxiliary line. The fixture transfer device 600 can be used to transfer the battery cell clamping fixture 400.

[0057] like Figure 4 As shown, an automatic battery cell loading and unloading device 700 is at least mounted on the fixture transfer device 600, and may include a pressure plate lifting mechanism and a battery cell clamping mechanism. The pressure plate lifting mechanism can adjust the spacing between adjacent pressure plates of the battery cell clamping fixture 400 using components such as claws, while the battery cell clamping mechanism can arrange the battery cell between adjacent pressure plates or remove the battery cell from between adjacent pressure plates using components such as claws, thereby achieving automatic loading and unloading of the battery cell within the battery cell clamping fixture 400. The automatic battery cell loading and unloading device 700 can be configured in two sets, with each set positioned at one end of the fixture transfer device 600, for assembling the battery cell into the battery cell clamping fixture 400 and removing the battery cell from the battery cell clamping fixture 400, respectively.

[0058] The continuous isostatic pressing production system for all-solid-state batteries may also include a cell transfer device 900, which can be configured as a linear line for transferring cells. Two sets of cell transfer devices 900 can be configured, each corresponding to one of two sets of automatic cell loading and unloading devices 700. One set of automatic cell loading and unloading devices 700 can assemble the cells from its corresponding cell transfer device 900 into the cell clamping fixture 400; while the other set of automatic cell loading and unloading devices 700 can remove the cells from the cell clamping fixture 400 and place them onto its corresponding cell transfer device 900.

[0059] like Figure 4 As shown, the jig loading / unloading device 800 can be positioned between the automatic cell loading / unloading device 700 and the barrel transfer device 500. It can include a robotic arm and a rotary platform. The robotic arm can be mounted on the rotary platform, which can drive the robotic arm to rotate, facilitating the transfer of the cell clamping jig 400 between the automatic cell loading / unloading device 700 and the barrel transfer device 500. Two sets of jig loading / unloading devices 800 can be configured, each corresponding to one of the two sets of automatic cell loading / unloading devices 700. These devices are used to load the cell clamping jig 400, which contains the cells, into the empty barrel 200, and to remove the cell clamping jig 400 after isostatic pressing from the barrel 200, respectively.

[0060] It is understood that by setting up the material cylinder transfer device 500, the fixture transfer device 600, the automatic battery cell loading and unloading device 700, and the fixture loading and unloading device 800, this embodiment can also realize the automatic loading and unloading of battery cells in the battery cell clamping fixture 400, as well as the automatic feeding and unloading of the battery cell clamping fixture 400 in the material cylinder 200, which has a higher degree of automation and is more convenient.

[0061] The implementation principle of the all-solid-state battery continuous isostatic pressing production system provided in this application embodiment is as follows: When the battery cell undergoes isostatic pressing, the battery cell is first assembled into the battery cell clamping fixture 400 using a set of battery cell loading and unloading devices. Then, the battery cell clamping fixture 400 is loaded into the material cylinder 200 using a set of fixture loading and unloading devices 800. Next, the drive mechanism 120 of the all-solid-state battery continuous isostatic pressing feeding device 100 provided in this application drives the feeding push rod 110 to move horizontally, so that the feeding push rod 110 abuts against the material cylinder 200. Simultaneously, the isostatic pressing cylinder 310 is moved to the first working position by the traversing mechanism 320. Subsequently, the drive mechanism 120 continues to drive the feeding push rod 110 to move, so that the feeding push rod 110 drives the material cylinder 200 to move synchronously horizontally, thereby loading the material cylinder 200 into the isostatic pressing device 300. Then, the traversing mechanism 320 moves the isostatic pressing cylinder 310 to the second working position to perform isostatic pressing on the battery cell. After the isostatic pressing of the battery cell is completed, the isostatic pressing cylinder 310 is moved back to the first working position by the traversing mechanism 320. At this time, the material cylinder 200 inside the isostatic pressing cylinder 310 can be squeezed out of the isostatic pressing cylinder 310 during the process of the next material cylinder 200 entering the isostatic pressing cylinder 310, thus achieving material discharge. After the material cylinder 200 is discharged, the battery cell clamping fixture 400 can be removed from the material cylinder 200 by another set of fixture loading and unloading devices 800, and then the battery cell can be removed from the battery cell clamping fixture 400 by another set of battery cell loading and unloading devices.

[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
