[0002] Battery formation is a key step in the battery manufacturing process. It is mainly used to activate the chemical substances inside the battery, form a stable electrode interface (such as SEI film, solid electrolyte interphase film), and ensure that the battery achieves its designed capacity and performance.

[0003] In existing technologies, batteries are generally formed using a formation cabinet. The formation cabinet typically has multiple fixtures arranged in rows inside. To further optimize the formation process, the individual batteries to be formed are pre-placed in a tray, and then the tray is transported to the formation cabinet via a transport system. However, battery formation involves multiple stages, including constant current charging, constant voltage charging, and resting, which is time-consuming and can easily lead to blockages or idling in the transport system.

[0018] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0019] The loading and unloading buffer device of this utility model uses a storage unit, a transport unit, and a lifting unit in cooperation. Along the z-axis, the transport unit extends at least partially to the bottom of the storage space, effectively allowing the tray carrying the batteries to be formed to be transported to the bottom of the storage space via the transport unit.

Then, the first cylinder drives the lifting section and the supporting section to rise, placing the tray carrying batteries to be formed into the storage space. After that, the second cylinder drives the lifting section and the supporting section to move backward, and the first cylinder drives the lifting section and the supporting section to fall, causing the lifting section and the supporting section to return to their original positions. This operation is repeated until the storage space for batteries to be formed is filled, effectively buffering the batteries to be formed.

[0044] The following will be combined with the appendix Figures 1-9 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0045] Please see Figures 1-9The loading and unloading buffer device 100 of this utility model embodiment includes a storage unit 10, a transport unit 20, and two lifting units 30. The storage unit 10 has a storage space 11. Along the z-axis direction, the transport unit 20 extends at least partially to the bottom of the storage space 11. Along the x-axis direction, the two lifting units 30 are arranged opposite to each other on both sides of the storage space 11. Each lifting unit 30 includes a lifting component 31. The lifting component 31 includes a first cylinder 311, a lifting part 312, a second cylinder 313, and a supporting part 314. The first cylinder 311 is disposed at the top of the storage space 11. The output shaft of the first cylinder 311 is connected to the lifting part 312 along the y-axis direction. The second cylinder 313 is disposed on one side of the storage space 11. The output shaft of the second cylinder 313 is connected to the side of the lifting part 312 away from the storage space 11 along the x-axis direction. The supporting part 314 is disposed on the side of the lifting part 312 facing the storage space 11.

[0046] Compared with the prior art, the loading and unloading buffer device 100 of this utility model uses the storage unit 10, the transport unit 20 and the lifting unit 30 in cooperation. Along the z-axis direction, the transport unit 20 extends at least partially to the bottom of the storage space 11, which effectively allows the tray 300 carrying the battery 200 to be formed to be transported to the bottom of the storage space 11 through the transport unit 20. Along the x-axis direction, the two lifting units 30 are arranged opposite to each other on both sides of the storage space 11. The two lifting units 30 work together to lift the battery 200 to be formed from the transport unit 20 and place it in the storage space 11, which effectively buffers the tray 300 carrying the battery 200 to be formed on the transport unit 20, effectively relieves the pressure of the transport system to transport the battery 200 to be formed, and avoids the transport system from being blocked or running idle. Each lifting unit 30 includes a first cylinder 311, a lifting part 312, a second cylinder 313, and a supporting part 314. The first cylinder 311 can drive the lifting part 312 and the supporting part 314 to rise or fall along the y-axis direction, and the second cylinder 313 can drive the lifting part 312 and the supporting part 314 to move forward or backward along the x-axis direction. When the transport unit 20 transports the tray 300 carrying the battery 200 to be formed to the bottom of the storage space 11, the second cylinder 313 drives the lifting part 312 and the supporting part 314 to move forward, and the supporting part 314 supports the battery. The tray 300, carrying the batteries 200 to be formed, is lifted by the first cylinder 311, which in turn raises the lifting part 312 and the supporting part 314. After placing the tray 300 into the storage space 11, the second cylinder 313 moves the lifting part 312 and the supporting part 314 backward, while the first cylinder 311 lowers them, resetting them to their original positions. This process is repeated until the storage space 11 is filled with the batteries 200 to be formed, effectively buffering the batteries 200. Furthermore, manual placement of the batteries 200 into the storage space 11 is eliminated, reducing manual operation time and errors, and effectively improving the automation level of the loading and unloading buffer device 100.

[0047] Understandably, during the transport of the battery 200 to be formed, the battery 200 is placed in the tray 300. Therefore, the support part 314 holds the battery 200 to be formed in the tray 300 and places it in the storage space 11 through the tray 300, thereby effectively preventing damage to the battery 200 to be formed during the movement of the battery 200.

[0048] Please see Figures 1-2 , Figure 4 , Figure 6 and Figure 8In some embodiments, the storage unit 10 includes a storage rack 12 and two storage sections 13. A storage space 11 is disposed on the storage rack 12. Along the x-axis, the two storage sections 13 are disposed opposite each other within the storage space 11, and each of the two storage sections 13 corresponds to one of the two lifting units 30. A first cylinder 311 is disposed on the top of the storage rack 12, and a second cylinder 313 is located on one side of the storage rack 12. Through the cooperative use of the storage rack 12 and the storage sections 13, the storage space 11 is disposed on the storage rack 12. When the battery 200 to be formed is placed in the storage space 11, the storage sections 13 located on both sides of the storage space 11 cooperate to support the battery 200 to be formed, effectively realizing the storage of the battery 200 to be formed.

[0049] Please see Figures 1-2 , Figure 4 , Figure 6 and Figure 8 In some embodiments, each storage unit 13 includes a movable support 131, a third cylinder 132, and a storage platform 133. The third cylinder 132 is disposed on one side of the storage rack 12 along the x-axis direction. The output shaft of the third cylinder 132 is connected to the side of the movable support 131 away from the storage space 11. The storage platform 133 is disposed on the side of the movable support 131 facing the storage space 11. A storage position is formed between the storage platforms 133 of the two storage units 13. With the coordinated use of the movable support 131, the third cylinder 132, and the storage platform 133, the storage platform 133 is set on the side of the movable support 131 facing the storage space 11, and a storage position is formed between the storage platforms 133 on both sides of the storage space 11. The storage position is used to place the battery 200 to be formed. The third cylinder 132 is used to drive the movable support 131 and the storage platform 133 to move forward or backward along the x-axis direction, which effectively makes the interval between the storage platforms 133 on both sides of the storage space 11 adjustable, thereby adjusting the size of the storage position so that the storage position can be compatible with various sizes of trays 300 or batteries 200 to be formed.

[0050] When the lifting assembly 31 raises the tray 300 containing the batteries 200 to be formed to above the target storage layer, the third cylinder 132 drives the storage platform 133 forward to support the tray 300. Then, the second cylinder 313 drives the lifting part 312 and the supporting part 314 backward, and the first cylinder 311 drives the lifting part 312 and the supporting part 314 downward. The lifting part 312 and the supporting part 314 then reset, ready to lift the next tray 300 containing the batteries 200 to be formed. This effectively buffers the batteries 200 to be formed, improving the automation level of the loading and unloading buffer device 100.

[0051] Please see Figures 1-2 , Figure 4 , Figure 6 and Figure 8 In some embodiments, multiple storage platforms 133 and multiple support portions 314 are provided. Multiple storage platforms 133 are spaced apart along the y-axis on the movable support 131, and multiple support portions 314 are spaced apart along the y-axis on the lifting portion 312, with each storage platform 133 and support portion 314 corresponding to the other. Through the coordinated use of multiple storage platforms 133 and multiple support portions 314, and by having multiple storage platforms 133 spaced apart along the y-axis on the movable support 131, multiple storage positions are effectively formed along the y-axis, effectively increasing the storage capacity of the upper and lower buffer mechanisms without occupying a large space.

[0052] With multiple storage platforms 133 and multiple support parts 314 arranged one-to-one, when storing the next tray 300 containing the battery 200 to be formed, the second cylinder 313 drives the lifting part 312 and the support part 314 forward, and the support part 314 supports the transport unit 20 and the tray 300 on the storage platform 133. The third cylinder 132 drives the storage platform 133 to move backward to avoid the rise of the tray 300 on the transport unit 20. The first cylinder 311 lifts the lifting unit 312 and the supporting unit 314, raising the pallet 300 above the target storage layer. Then, the third cylinder 132 moves the storage platform 133 forward to support the pallet 300. Next, the second cylinder 313 moves the lifting unit 312 and the supporting unit 314 backward, while the first cylinder 311 lowers them. The lifting unit 312 and the supporting unit 314 then reset, ready to lift the next pallet 300 containing the battery 200 to be formed. Through the coordinated operation of the first cylinder 311, the second cylinder 313, and the third cylinder 132, a single pallet 300 is effectively transferred from the transport unit 20 to the target storage layer of the storage rack 12. When the transport unit 20 delivers a new pallet 300, the storage platform 133 moves backward via the third cylinder 132 to create vertical lifting space, avoiding mechanical interference with the supporting unit 314 during lifting and ensuring smooth operation of the multi-layer storage unit during high-density storage.

[0053] It is understood that the supporting part 314 supports the pallet 300 on the transport unit 20 and the storage platform 133. That is, among the multiple supporting parts 314, the supporting part 314 corresponding to the pallet 300 on the transport unit 20 supports the pallet 300 on the transport unit 20; among the multiple supporting parts 314, the supporting part 314 corresponding to the pallet 300 on the storage platform 133 supports the pallet 300 on the storage platform 133.

[0054] Please see Figures 1-2 , Figure 4 and Figures 6-8In some embodiments, a guide portion 134 is provided on the storage platform 133. The guide portion 134 is used to assist in the extraction of the tray 300 located on the storage platform 133.

[0055] Furthermore, the guide section 134 includes a plurality of first rollers 1341 and a plurality of second rollers 1342. Along the z-axis, the first rollers 1341 are spaced apart on the upper surface of the storage platform 133, and the second rollers 1342 are spaced apart on the side of the storage platform 133 opposite to the movable support 131. Through the cooperative use of the first rollers 1341 and the second rollers 1342, when a tray 300 carrying batteries 200 to be formed is placed on the storage platform 133, the sides of the first rollers 1341 contact the sides of the tray 300, and the sides of the second rollers 1342 contact the bottom of the tray 300. The second rollers 1342, spaced apart along the z-axis, form support points for the tray 300, while the first rollers 1341, spaced apart along the z-axis, restrict the tray 300, preventing displacement. When the tray 300 containing the battery 200 to be formed is removed from the storage platform 133, the tray 300 is pulled, the first roller 1341 and the second roller 1342 roll, and the auxiliary tray 300 is removed along the z-axis.

[0056] Please see Figures 1-3 In some embodiments, the transport unit 20 includes a conveying component 21 and a lifting component 22. The lifting component 22 is disposed at the bottom of the storage space 11. Along the z-axis, one end of the conveying component 21 is disposed on the lifting component 22, and the other end of the conveying component 21 extends to the front side of the storage rack 12. Through the cooperative use of the conveying component 21 and the lifting component 22, the conveying component 21 is used to transport the tray 300 carrying the battery 200 to be formed to the bottom of the storage space 11, and the lifting component 22 lifts the tray 300 located on the conveying component 21, so that the subsequent support part 314 can support the tray 300.

[0057] Please see Figures 1-3In some embodiments, the conveying assembly 21 includes a support platform 211 and a conveyor belt 212, and the lifting assembly 22 includes a fourth cylinder 221 and a U-shaped support 222. The U-shaped support 222 is disposed at the bottom of the storage space 11, the fourth cylinder 221 is disposed on the U-shaped support 222, the support platform 211 is disposed at the front side of the storage rack 12, along the z-axis direction, one end of the conveyor belt 212 is disposed on the U-shaped support 222, and the other end of the conveyor belt 212 is disposed on the support platform 211. Through the coordinated use of the support platform 211, conveyor belt 212, fourth cylinder 221, and U-shaped support 222, the U-shaped support 222 and the support platform 211 work together to support the conveyor belt 212. The conveyor belt 212 is used to transport the tray 300 carrying the batteries 200 to be formed to the bottom of the storage space 11. The output shaft of the fourth cylinder 221 lifts the tray 300 located on the conveyor belt 212, making it easier for the subsequent support part 314 to support the tray 300. In addition, through the setting of the U-shaped support 222, the U-shaped support 222 not only provides support for the conveyor belt 212, but the U-shaped opening of the U-shaped support 222 also provides clearance space for the output shaft of the fourth cylinder 221.

[0058] Furthermore, the conveyor belt 212 includes two synchronous belts, spaced apart along the x-axis. One end of one of the synchronous belts is positioned on one side of the U-shaped opening of the U-shaped support 222, and one end of the other synchronous belt is positioned on the other side of the U-shaped opening of the U-shaped support 222. The other ends of both synchronous belts are positioned on the support platform 211. During the process of conveying the tray 300 carrying the battery 200 to be formed via the two synchronous belts, along the x-axis, one side of the tray 300 is located on one of the two synchronous belts, and the other side of the tray 300 is located on the other synchronous belt. This effectively allows the output shaft of the fourth cylinder 221 to pass through the U-shaped opening of the U-shaped support 222 and lift the tray 300.

[0059] Furthermore, the output shaft of the fourth cylinder 221 is connected to a lifting plate 223. Limiting rods 224 are provided at the four corners of the lifting plate 223. The U-shaped support 222 has limiting holes corresponding to the limiting rods 224. The limiting rods 224 pass through the limiting holes, and the limiting rods 224 and the limiting holes are slidably connected. During use, the fourth cylinder 221 can lift the pallet 300 through the lifting plate 223, effectively improving the stability of the lifting assembly 22 in lifting the pallet 300. During the process of the fourth cylinder 221 driving the lifting plate 223 to rise or fall, the limiting rods 224 located at the four corners of the lifting plate 223 form a rectangular guide frame, effectively restricting the lifting plate 223 from rising or falling in the y-axis direction, preventing the lifting plate 223 from shifting or rotating, thereby improving the stability during the lifting of the pallet 300.

[0060] Please see Figures 1-4In some embodiments, the upper and lower buffer mechanism further includes a first sliding component 40, which includes a first slide rail 41 and a first slider 42. The first slider 42 is slidably connected to the first slide rail 41. Specifically, along the x-axis, the first slide rail 41 is located at the top of the storage rack 12, and the first slider 42 is located at the top of the movable support 131; and / or, along the x-axis, the first slide rail 41 is located at the bottom of the storage rack 12, and the first slider 42 is located at the bottom of the movable support 131. The first sliding component 40 assists in the forward or backward movement of the movable support 131, improving its stability. The first sliding component 40 includes a first slide rail 41 and a first slider 42 slidably connected to the first slide rail 41. The movable support 131 is slidably connected to the first slide rail 41 of the storage rack 12 through the first slider 42, which effectively restricts the movable support 131 from moving forward or backward in the x-axis direction, effectively guides the moving support 131 to move forward or backward, and improves the stability of the moving support 131 moving forward or backward.

[0061] When the top and bottom of the movable support 131 are both provided with first sliders 42, and the top and bottom of the storage rack 12 are both provided with first slide rails 41, the stability of the movable support 131 moving forward or backward is further improved, and structural vibration is reduced.

[0062] Please see Figures 1-2 , Figure 4 , Figure 6 and Figure 8 In some embodiments, along the y-axis, the lifting part 312 includes a first segment 3121, a second segment 3122, and a third segment 3123. The second segment 3122 connects the first segment 3121 and the third segment 3123. The thickness of the second segment 3122 is greater than the thickness of the first segment 3121 and the third segment 3123. The output shaft of the first cylinder 311 is connected to the first segment 3121, and the output shaft of the second cylinder 313 is connected to at least one of the first segment 3121, the second segment 3122, and the third segment 3123. Through the cooperative use of the first segment 3121, the second segment 3122, and the third segment 3123, the second segment 3122 connects the first segment 3121 and the third segment 3123. Since the second segment 3122 is located in the middle of the lifting part 312, and its thickness is greater than the thickness of the first segment 3121 and the second segment 3122, the structural strength of the lifting part 312 is effectively enhanced, preventing the lifting part 312 from bending and deforming.

[0063] Furthermore, transition sections are provided between the first segment 3121 and the second segment 3122, and between the third segment 3123 and the second segment 3122. The thickness of the transition sections gradually increases from the first segment 3121 towards the second segment 3122 and from the third segment 3123 towards the second segment 3122. This effectively reduces the overall weight of the lifting unit 312 while maintaining structural rigidity and preventing the lifting unit 312 from bending or deforming.

[0064] Please see Figures 1-2 , Figure 4 , Figure 6 and Figures 8-9 In some embodiments, the upper and lower buffer mechanism further includes a second sliding component 50, which includes a second slide rail 51 and a second slider 52. The second slider 52 is slidably connected to the second slide rail 51. The second slide rail 51 is disposed in the first segment 3121 and / or the third segment 3123, and the second slider 52 is connected to the output shaft of the second cylinder 313. The second sliding component 50 assists in the raising or lowering of the lifting part 312, improving the stability of the lifting part 312's raising or lowering. The second sliding component 50 includes a second slide rail 51 and a second slider 52 slidably connected to the second slide rail 51. The lifting part 312 is slidably connected to the output shaft of the second cylinder 313 via the second slider 52 through the second slide rail 51, effectively limiting the raising or lowering of the lifting part 312 along the y-axis direction, effectively guiding the raising or lowering of the lifting part 312, and improving the stability of the raising or lowering of the lifting part 312.

[0065] Since the thickness of the second segment 3122 is greater than the thickness of the first segment 3121 and the third segment 3123, the second slide rail 51 is positioned on the first segment 3121 and / or the third segment 3123. The thicker structure of the second segment 3122 can serve as a clear limiting boundary. This effectively limits the rise or fall of the lifting part 312, preventing problems such as tray 300 collision and battery damage caused by excessive lifting.

[0066] Please see Figures 1-2 , Figures 4-6 and Figure 8In some embodiments, each lifting unit 30 further includes a movable frame 32. Along the x-axis, the movable frame 32 is slidably mounted on the top of the storage rack 12. Each lifting unit 30 has multiple lifting components 31. Along the z-axis, the first cylinders 311 of the multiple lifting components 31 of each lifting unit 30 are spaced apart on the movable frame 32. By configuring the movable frame 32, the first cylinders 311 of the multiple lifting components 31 of each lifting unit 30 are spaced apart on the movable frame 32, effectively forming a modular unit with the movable frame 32. The multiple lifting components 31 move synchronously through the movable frame 32, improving the stability of the lifting tray 300 and increasing operational efficiency.

[0067] Furthermore, a fifth cylinder 33 is provided on the storage rack 12, and the output shaft of the fifth cylinder 33 is connected to the movable frame 32 along the x-axis. The fifth cylinder 33 can drive the movable frame 32 to move forward or backward along the x-axis, effectively reducing the load on the second cylinder 313.

[0068] Furthermore, a third sliding assembly 60 is provided between the top of the movable frame 32 and the top of the storage rack 12. The third sliding assembly 60 includes a third slide rail 61 and a third slider 62, which are slidably connected to the third slide rail 61. The third slide rail 61 is located at the top of the storage rack 12, and the third slider 62 is located at the bottom of the movable frame 32. The third sliding assembly 60 assists in the forward or backward movement of the movable frame 32, improving its stability. The third sliding assembly 60 includes a third slide rail 61 and a third slider 62 slidably connected to it. The movable frame 32 is slidably connected to the third slide rail 61 of the storage rack 12 via the third slider 62, effectively limiting the forward or backward movement of the movable frame 32 along the x-axis, effectively guiding its movement and improving its stability.
