Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0037] The embodiments of the present application are introduced below in conjunction with the accompanying drawings of the specification:

[0038] Reference Figures 1 to 5 , according to the hot pressing device of the embodiment of the present application, including a carrying component 100, a lifting component 200, a hot pressing component 300, and a driving component 400. The lifting component 200 includes a lifting member 210 and a transmission member 220. The lifting member 210 is connected to the transmission member 220. The transmission member 220 is provided with a first through hole 221 in the vertical direction. At least a part of the lifting member 210 is inserted into the first through hole 221. The hot pressing component 300 is connected to the lifting member 210. The driving component 400 is connected to the carrying component 100, and the driving component 400 is drivingly connected to the outer peripheral wall of the transmission member 220. Among them, the driving component 400 is configured to drive the transmission member 220 to rotate relative to the carrying component 100 to drive the lifting member 210 to move vertically relative to the transmission member 220. The driving component 400 is drivingly connected to the outer peripheral wall of the transmission member 220 to avoid the lifting member 210 inserted in the first through hole 221, so as to prevent the lifting member 210 from being hindered from moving vertically relative to the transmission member 220, improving the utilization rate of the height space, and making the hot pressing device more compact in the vertical direction.

[0039] Specifically, by providing a first through hole 221 in the transmission member 220, the lifting member 210 is passed through the first through hole 221, and the driving assembly 400 is drivingly connected to the outer peripheral wall of the transmission member 220, effectively avoiding the interference of the driving connection between the driving assembly 400 and the transmission member 220 on the vertical lifting of the lifting member 210. That is, in the vertical direction, the part where the driving assembly 400 and the transmission member 220 are connected is at the same height as at least a part of the lifting member 210, and at least a part of the driving assembly 400, the lifting member 210, and the transmission member 220 are arranged at the same height, effectively reducing the occupation of the height space by the hot pressing device and improving the compactness of the hot pressing device in the vertical direction.

[0040] It should be noted that the driving assembly 400 and the transmission member 220 can be drivingly connected through a transmission belt. The outer peripheral wall of the transmission member 220 serves as a pulley and abuts against the transmission belt. A thread is provided in the first through hole 221, and a thread is also provided on the outer peripheral wall of the lifting member 210. The lifting member 210 is threadedly connected to the transmission member 220. The transmission member 220 drives the lifting member 210 to move relative to the transmission member 220 in the vertical direction by rotation, and the hot pressing member 300 moves synchronously with the lifting member 210 in the vertical direction to achieve hot pressing of the battery cell. The connection between the transmission belt and the transmission member 220 can avoid the movement of the lifting member 210 in the vertical direction, preventing the connection between the transmission belt and the transmission member 220 from interfering with the lifting of the lifting member 210, effectively reducing the occupation of the height space by the hot pressing device. Thus, in the vertical direction, the structure of the hot pressing device is more compact.

[0041] Reference Figure 3 , in some other embodiments, the transmission member 220 may include a pulley structure and a threaded transmission structure. The pulley structure is connected to the transmission belt, and the threaded transmission structure is provided with an internal thread for threaded connection with the lifting member 210. The pulley structure is connected to the threaded transmission structure, and the pulley structure surrounds the threaded transmission structure in the horizontal direction and abuts against the outer peripheral wall of the threaded transmission structure. The pulley structure and the threaded transmission structure rotate synchronously. Splitting the transmission member 220 facilitates the separate processing and manufacturing of the pulley structure and the threaded transmission structure, reducing the production difficulty. In addition, when the transmission member 220 is damaged, only the damaged part needs to be replaced, which is beneficial to reducing the maintenance cost.

[0042] It should be noted that the pulley structure and the threaded transmission structure can be installed sequentially in the vertical direction, facilitating the sequential disassembly of the pulley structure and the threaded transmission structure, and making disassembly and maintenance more convenient.

[0043] Reference Figures 1 to 5, in some embodiments, the carrier assembly 100 includes a first substrate 110 and a rotating member 130. The first substrate 110 is connected to the rotating member 130. The rotating member 130 is provided with a second through hole 131. Along the vertical direction, at least a part of the transmission member 220 passes through the second through hole 131. The outer peripheral wall of the transmission member 220 abuts against the side wall of the second through hole 131. The rotating member 130 is used to support the relative rotation of the transmission member 220 with respect to the first substrate 110, increasing the smoothness of the rotation of the transmission member 220 and the first substrate 110. In addition, at least a part of the transmission member 220 passes through the second through hole 131, so that along the vertical direction, the height of the transmission member 220 is the height of the cooperation between the transmission member 220 and the rotating member 130, effectively avoiding the increase in the height of the hot pressing device and ensuring the structural compactness of the hot pressing device along the vertical direction.

[0044] Specifically, the rotating member 130 surrounds the outer peripheral wall of the transmission member 220 along the horizontal direction and abuts against the outer peripheral wall of the transmission member 220. The lifting member 210 moves relative to the transmission member 220 along the vertical direction. The transmission member 220 is mainly subjected to a force along the vertical direction. The rotating member 130 can be a bearing with axial load-bearing capacity such as a thrust ball bearing. The rotating member 130 includes a first fixing portion fixedly connected to the first substrate 110 and a second fixing portion fixedly connected to the transmission member 220. The first fixing portion and the second fixing portion are connected by rolling members to realize the relative rotation of the first fixing portion and the second fixing portion, and further realize the relative rotation between the transmission member 220 and the first substrate 110. Thus, on the basis of improving the smoothness of the rotation between the transmission member 220 and the first substrate 110, the occupation of the height space by the hot pressing device is reduced, which is beneficial to adapting to the working scenario with limited height space.

[0045] Reference Figures 1 to 5 , in some embodiments, along the vertical direction, the first substrate 110 is provided with a third through hole 111. The lifting assembly 200 is located on one side of the first substrate 110, and the hot pressing member 300 is located on the other side of the first substrate 110. The lifting member 210 passes through the third through hole 111 from one side of the first substrate 110 and extends to the other side of the first substrate 110. The lifting member 210 is simultaneously connected to the transmission member 220 and the hot pressing member 300. Placing the transmission member 220 on one side of the first substrate 110 and the hot pressing member 300 on the other side of the first substrate 110 facilitates the maintenance of the lifting assembly 200 and the hot pressing member 300 respectively.

[0046] Specifically, the hot pressing device can be arranged in the vertical direction, such that the lifting assembly 200 is located above the first substrate 110, the hot pressing member 300 is located below the first substrate 110, and the transmission member 220 is located above the first substrate 110 for driving the lifting member 210 to move in the vertical direction. The lifting member 210 is connected to the hot pressing member 300 to drive the hot pressing member 300 located below the first substrate 110 to move in the vertical direction for the hot pressing battery core. Thus, only the lifting assembly 200 needs to be disassembled for maintaining the lifting assembly 200, and the overall hot pressing device is not required to be disassembled, which is beneficial to shortening the maintenance time.

[0047] Reference Figures 3 to 5 , in some other embodiments, the third through hole 111 extends in the vertical direction, at least a part of the rotating member 130 is located in the third through hole 111 and abuts against the side wall of the third through hole 111, realizing the mating installation of the rotating member 130 and the first substrate 110, reducing the mating height between the rotating member 130 and the first substrate 110, and further making the structure of the hot pressing device more compact in the vertical direction.

[0048] It should be noted that the rotating member 130 is provided with a second through hole 131, and at least a part of the transmission member 220 is located in the second through hole 131, such that the part where the transmission member 220 and the rotating member 130 cooperate is located in the third through hole 111.

[0049] Reference Figures 3 to 5 , in some embodiments, the first substrate 110 is further provided with a protruding portion 112. The protruding portion 112 is located in the third through hole 111, the protruding portion 112 protrudes outward from the side wall of the third through hole 111, at least a part of the rotating member 130 is located in the third through hole 111, and the protruding portion 112 abuts against the rotating member 130. The protruding portion 112 is used to support the rotating member 130, increasing the stability of the cooperation between the rotating member 130 and the first substrate 110.

[0050] Specifically, the rotating member 130 is used to bear the axial force, and the protruding portion 112 provides support for the rotating member 130 in the vertical direction. Compared with the rotating member 130 abutting against the side wall of the third through hole 111 in the horizontal direction, the stability of the cooperation between the rotating member 130 and the first substrate 110 is further improved.

[0051] It should be noted that, in the horizontal direction, there is a gap between the protruding portion 112 and the lifting member 210. While the protruding portion 112 abuts against the rotating member 130, it avoids interfering with the movement of the lifting member 210 in the vertical direction.

[0052] Reference Figures 3 to 5, in some other embodiments, the rotating member 130 is located within the third through hole 111. Along the horizontal direction, the rotating member 130 abuts against the side wall of the third through hole 111. The height at which the first substrate 110 and the rotating member 130 cooperate is the height of the first substrate 110 or the rotating member 130 along the vertical direction, further reducing the overall height of the hot pressing device.

[0053] It should be noted that the rotating member 130 is located within the third through hole 111, the transmission member 220 abuts against the rotating member 130, and along the horizontal direction, there is a gap between the transmission member 220 and the first substrate 110 to prevent the transmission member 220 from coming into contact with the first substrate 110 and ensure the smooth rotation of the transmission member 220 relative to the first substrate 110.

[0054] Reference Figures 3 to 5 , in some embodiments, the carrying assembly 100 further includes a guiding member 140. The guiding member 140 is connected to the first substrate 110, and the hot pressing member 300 is slidably connected to the guiding member 140. Both the guiding member 140 and the lifting member 210 extend along the vertical direction. The guiding member 140 is used to guide the movement of the hot pressing member 300, prevent the hot pressing member 300 from deflecting during movement, which is beneficial to improving the uniformity of hot pressing the battery cell and enhancing the hot pressing quality of the battery cell.

[0055] It should be noted that the hot pressing member 300 includes a horizontal hot pressing surface, and the hot pressing member 300 moves along the vertical direction, which is beneficial for better fitting the battery cell.

[0056] Reference Figures 3 to 5 , in some other embodiments, there are multiple guiding members 140. The multiple guiding members 140 all extend along the vertical direction, and the hot pressing member 300 is simultaneously slidably connected to the multiple guiding members 140, enabling the hot pressing member 300 to move along the vertical direction relative to the multiple guiding members 140 simultaneously. The multiple guiding members 140 further ensure the stability of the vertical movement of the hot pressing member 300, prevent the movement path of the hot pressing member 300 from deflecting relative to the vertical direction, and further improve the quality of the hot pressed battery cell.

[0057] Reference Figures 3 to 5 , in some embodiments, the carrying assembly 100 further includes a second substrate 120. The second substrate 120 is connected to the guiding member 140. Along the vertical direction, the hot pressing member 300 is located between the first substrate 110 and the second substrate 120. The second substrate 120 is used to carry the battery cell. The hot pressing member 300 is slidably connected to the guiding member 140. The horizontal hot pressing surface on the hot pressing member 300 is perpendicular to the guiding member 140. The second substrate 120 has a horizontal carrying surface. The second substrate 120 is connected to the guiding member 140, and the horizontal carrying surface on the second substrate 120 is perpendicular to the guiding member 140, thus ensuring the parallelism between the horizontal hot pressing surface and the horizontal carrying surface, which is beneficial to improving the quality of the hot pressed battery cell.

[0058] Reference Figures 3 to 5 In some embodiments, the first substrate 110 and the second substrate 120 are connected by a plurality of guiding members 140. Each guiding member 140 extends in the vertical direction. The hot pressing member 300 is connected to the lifting member 210 and is slidably connected to each guiding member 140, which is beneficial to ensuring the parallelism of the first substrate 110, the second substrate 120 and the hot pressing member 300, and beneficial to improving the smoothness and quality of hot pressing.

[0059] Reference Figures 3 to 5 In other embodiments, the hot pressing member 300 includes a heating plate 310 and a pressing plate 320. The heating plate 310 and the pressing plate 320 are connected. The heating plate 310 is also connected to the lifting member 210. In the vertical direction, the pressing plate 320 is located below the heating plate 310. The heating plate 310 is used to generate heat, and the pressing plate 320 is used to receive the heat generated by the heating plate 310. Compared with the heating plate 310 directly contacting the battery cell, the heat distribution on the pressing plate 320 is more uniform, which is beneficial to avoiding local overheating of the battery cell and ensuring the yield rate of the battery cell. In addition, the heating plate 310 and / or the pressing plate 320 are also slidably connected to the guiding member 140 to avoid tilting during hot pressing and ensure the stability of hot pressing.

[0060] It should be noted that the heating plate 310 usually generates heat by means of resistance heating, etc. The pressing plate 320 can be made of a material with good thermal conductivity. The heat generated by the heating plate 310 can be quickly conducted on the pressing plate 320 and evenly distributed on the pressing plate 320. The setting of the pressing plate 320 is beneficial to avoiding local overheating of the battery cell and ensuring the hot pressing quality of the battery cell.

[0061] Reference Figures 1 to 3 In some embodiments, the carrier assembly 100 further includes a fixing member 150. The fixing member 150 is connected to the first substrate 110. In the horizontal direction, the fixing member 150 is distributed around the rotating member 130 and abuts against the outer peripheral wall of the rotating member 130, which is used to limit the shaking of the rotating member 130 and ensure the stability of the installation of the rotating member 130. In addition, there is a gap between the fixing member 150 and the transmission member 220, which is used to avoid the transmission member 220 and prevent friction between the transmission member 220 and the fixing member 150 when the transmission member 220 rotates, which is beneficial to ensuring the smooth rotation of the transmission member 220.

[0062] It should be noted that the fixing member 150 is located above the first substrate 110, and in the vertical direction, the height of the fixing member 150 does not exceed the height of the transmission member 220, so as to avoid increasing the overall height of the hot pressing device and ensure that the structure of the hot pressing device in the vertical direction is more compact.

[0063] Reference Figures 1 to 5, in some embodiments, along the horizontal direction, the driving assembly 400 is located on one side of the lifting assembly 200, and along the vertical direction, the height of the driving assembly 400 does not exceed the height of the transmission member 220, that is, the driving assembly 400 is horizontally arranged on one side of the lifting assembly 200, which is beneficial to limiting the overall height of the hot pressing device.

[0064] It should be noted that the transmission between the transmission member 220 and the driving assembly 400 can be realized through transmission structures such as transmission belts and transmission chains, which is beneficial to ensuring the horizontal transmission between the transmission member 220 and the driving assembly 400. Compared with other transmission methods such as gear transmission, it is also beneficial to reduce the transmission cost.

[0065] Reference Figures 1 to 5 , in some embodiments, the driving assembly 400 includes a driving member 410 and a speed reducing member 420. The driving member 410 is connected to the speed reducing member 420, and the speed reducing member 420 is connected to the transmission member 220. The speed reducing member 420 is located above the driving member 410. Specifically, along the vertical direction, the speed reducing member 420 and the transmission member 220 are at the same height. The speed reducing member 420 can be connected to the transmission member 220 through a transmission belt, so that the highest point of the driving assembly 400 does not exceed the highest point of the transmission member 220, which is beneficial to improving the compactness of the hot pressing device along the vertical direction.

[0066] It should be noted that the speed reducing member 420 may include a sun gear, a plurality of planet gears and an outer gear ring. For example, the speed reducing member 420 is a planetary speed reducer. The driving member 410 is connected to the sun gear, and the plurality of planet gears are meshed with the sun gear to increase the torque output by the speed reducing member 420, thereby increasing the pressure exerted by the hot pressing member 300 on the battery cell, which is beneficial to more tightly hot pressing the battery cell.

[0067] Reference Figures 1 to 5 , the production equipment according to the embodiments of the present application includes a conveying device and the hot pressing device in any of the above embodiments. The hot pressing device is connected to the conveying device.
