Description

Technical Field

[0001] This utility model relates to the field of battery technology, and specifically to a static system. Background Technology

[0002] In the battery production process, the tray only serves as a carrier for transporting batteries and does not participate in the specific manufacturing process of the batteries.

[0003] Pallets are required in all stages of battery production, especially in the formation process. During the settling phase, after electrolyte filling, batteries need to be placed in a settling chamber for a period of time. Pallets filled with batteries are transferred to the settling chamber and placed in their designated areas. Because the settling time is often long, exceeding 12 hours, and a single pallet has limited capacity, a large number of pallets are needed during this phase. Simultaneously, battery production continues, further increasing the number of pallets required; a single production line may require nearly 10,000 pallet fixtures. Due to this large quantity, the increased costs and impact on the company's economic efficiency caused by pallets cannot be ignored. Utility Model Content

[0004] In view of this, the present invention provides a static system to solve the problem of high system investment costs caused by placing a tray containing batteries in the static system in the prior art.

[0005] In a first aspect, this utility model provides a static system, comprising:

[0006] A stacker crane includes forks, on which multiple sets of clamping assemblies are provided; the stacker crane has a pickup position.

[0007] A lifting device is located below the picking position; the lifting device includes a lifting mechanism, the lifting mechanism includes a lifting drive mechanism and a lifting platform, and the lifting platform is located at the drive end of the lifting drive mechanism;

[0008] The tray is provided with multiple receiving platforms, on which batteries are adapted to be placed; the bottom of the tray on the side of the receiving platform is provided with a first clearance hole, and the lifting platform is adapted to extend upward through the first clearance hole to lift the batteries on the tray upward;

[0009] The shelf has a placement platform; when the battery is lifted above the tray by the lifting device, the clamping assembly clamps the battery and transfers the battery to the placement platform.

[0010] Beneficial Effects: In operation, the battery-loaded pallet of this storage system is transported to the stacker crane's picking position. A lifting drive mechanism raises the lifting platform, whose upper part extends upwards through a first clearance hole at the bottom of the pallet. The lifting platform abuts against the bottom of the battery and lifts it upwards, detaching the battery from the pallet. The forks move to the battery location, and multiple clamping components simultaneously grip multiple batteries. The batteries are then placed on a shelf platform and left to rest within the shelf. Since the batteries are placed directly within the shelf, no pallet is needed during the storage process, achieving pallet-free storage and significantly reducing pallet usage and investment costs. Furthermore, with the pallet directly placed in the shelf and the batteries unencased by a pallet frame, they are fully exposed to the environment, improving heat dissipation and heating, shortening storage time, and ultimately increasing production efficiency.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] The following is combined with Figures 1 to 10 The following describes embodiments of the present invention.

[0026] According to an embodiment of the present invention, a stationary system is provided, including a stacker crane, a lifting device 2, a pallet 3, and a shelf 4.

[0027] The stacker crane includes forks 1, which are equipped with multiple clamping components 11; the stationary system has a picking position 5; a lifting device 2 is located below the picking position 5; the battery 6 is suitable for being placed in a pallet 3; the bottom of the pallet 3 is provided with a first clearance hole 31, and the lifting device 2 is suitable for lifting the battery 6 upward through the first clearance hole 31; when the battery 6 is lifted above the pallet 3 by the lifting device 2, the clamping components 11 clamp the battery 6 and transfer the battery 6 to the shelf 4.

[0028] When this stationary system is in operation, the pallet 3 containing the batteries 6 is conveyed to the picking position 5 of the stationary system. The lifting device 2 lifts the batteries 6 upward through the first clearance hole 31, so that the batteries 6 are detached from the pallet 3. The forks 1 move to the batteries 6, and multiple sets of clamping components 11 simultaneously clamp multiple batteries 6, and then place the batteries 6 in the shelf 4 for stationary placement. The batteries 6 are placed directly in the shelf 4 for stationary placement, and the pallet 3 is not needed during the battery stationary placement process. The stationary system achieves pallet-free stationary placement, which can greatly reduce the number of pallets 3 used, thereby reducing the investment cost of pallets 3. At the same time, with the pallet 3 placed directly in the shelf 4 for stationary placement, the batteries 6 are not wrapped by the outer frame of the pallet 3, which can fully expose the batteries 6 to the environment, improve the heat dissipation or heating effect of the batteries 6, shorten the battery stationary placement time, and help improve production efficiency.

[0029] In some embodiments, the fork 1 includes a support platform 12, and multiple sets of clamping components 11 are spaced apart on the top surface of the support platform 12. When the battery 6 is lifted by the lifting device 2 above the tray 3, the lifting device 2 contacts part of the bottom surface of the battery 6 to reserve a space for the fork 1 to clamp on the bottom surface of the battery cell. The fork 1 extends to the bottom of the reserved space of the battery 6 to clamp the battery 6 from the bottom. After clamping, the bottom surface of the battery 6 abuts against the top surface of the support platform 12, and the fork 1 can stably clamp and transfer the battery 6.

[0030] In other embodiments, the clamping assembly 11 may also be disposed on the bottom surface of the support platform 12, and the fork 1 moves to the top of the battery 6, and the clamping assembly 11 clamps the battery 6 from the top of the battery 6.

[0031] In some embodiments, such as Figure 9 As shown, the fork 1 also includes a clamping drive mechanism. Each clamping assembly 11 includes two clamping plates 111. The clamping drive mechanism connects at least one clamping plate 111 of each clamping assembly 11. The two clamping plates 111 are opposite to each other and movably disposed on the support platform 12. The clamping assembly 11 is initially in the open state. The fork 1 moves to below the battery 6, and the fork 1 moves upward. The two clamping plates 111 of each clamping assembly 11 are located outside the two large surfaces of each battery 6. The clamping drive mechanism drives the clamping plates 111 to move toward the battery 6 to stably clamp the battery 6 from both sides.

[0032] In some embodiments, a clamping drive mechanism is connected to one of the clamping plates 111 of each set of clamping components 11, the two clamping plates 111 are opposite each other and one of the movable clamping plates 111 can move relative to the fixed clamping plate 111 to clamp or release the battery 6.

[0033] In some embodiments, such as Figure 9 As shown, the support platform 12 has a receiving cavity, and the clamping drive is located in the receiving cavity; the support platform 12 has a sliding groove 121 communicating with the receiving cavity, and the clamping plate 111 is slidably located in the sliding groove 121. The clamping drive is located in the receiving cavity, which can effectively reduce the space occupied by the forks 1. The clamping drive drives the clamping plate 111 to slide stably and smoothly along the sliding groove 121, which is conducive to the smooth clamping or release of the battery 6.

[0034] like Figure 9 As shown, in some embodiments, the two clamping plates 111 of each clamping assembly 11 form a clamping cavity, and a first guide ramp 1111 is provided on the top of the side of the clamping plate 111 facing the clamping cavity. During the process of the fork 1 loading the battery 6 from the bottom, when the clamping plate 111 contacts the battery 6, the battery 6 can slide into the clamping cavity along the first guide ramp 1111, which is conducive to the rapid entry of the battery 6 into the clamping cavity and can improve the production cycle.

[0035] like Figure 10 As shown, in some embodiments, the shelf 4 includes a support frame 41 and multiple sets of support legs 42. The support legs 42 are suspended on the inner wall of the support frame 41, and a clearance space is formed between the bottom of the support legs 42 and the support frame 41 for the forks 1 to pass through. The forks 1 are adapted to place multiple batteries 6 on multiple support legs 42 simultaneously. The batteries 6 are lifted to a predetermined height by the lifting device 2, and the forks 1 extend from the bottom of the batteries 6 to the bottom of the batteries 6. The clamping assembly 11 clamps the batteries 6, the lifting device 2 descends, and the forks 1 remove the batteries 6 and transfer them to the shelf 4. The support legs 42 of the shelf 4 are suspended on the support frame 41. When the forks 1 deliver the batteries 6 into the shelf 4, the forks 1 enter the shelf 4 from above the support legs 42, with the batteries 6 located above the support legs 42. After the forks 1 move into position, the forks 1 move down, placing the batteries 6 on top of the support legs 42. The forks 1 continue to move down, so that the clamping assembly 11 is located below the batteries 6, and the forks 1 can then exit the shelf 4. The support leg 42 is suspended in the air to facilitate the entry and exit of the fork 1 into and out of the shelf 4.

[0036] like Figure 10 As shown, in some embodiments, the shelf 4 is provided with multiple sets of support legs 42, with two support legs 42 in each set arranged opposite to each other on the support frame 41. The top of the support leg 42 is provided with a groove 421, and the battery 6 is placed in the groove 421 so that the battery 6 is stably held on the support leg 42.

[0037] In some embodiments, such as Figure 10 As shown, the support leg 42 has a second guide ramp 422 on the side facing the groove 421. During the process of the fork 1 placing the battery 6 into the groove 421 from above, the bottom of the battery 6 slides into the groove 421 along the second guide ramp 422, facilitating quick positioning of the battery 6. Figure 10 As shown, the second guide ramps 422 on the two oppositely arranged support legs 42 are arranged opposite each other.

[0038] In some embodiments, the lifting device 2 includes a lifting mechanism 21, which includes a lifting drive mechanism 211 and a lifting platform 212. The lifting platform 212 is located at the drive end of the lifting drive mechanism 211. The tray 3 is provided with a plurality of receiving platforms 32111, and the battery 6 is adapted to be placed on the receiving platform 32111. A first clearance hole 31 is provided on the side of the receiving platform 32111. The lifting platform 212 is adapted to extend upward through the first clearance hole 31 to lift the battery 6 upward.

[0039] In some embodiments, such as Figure 5 and Figure 6 As shown, the tray 3 includes multiple positioning components 32. The positioning components 32 are disposed on the bottom wall of the tray 3, and the top of the positioning components 32 is provided with a positioning groove 3211. The bottom of the positioning groove 3211 forms a receiving platform 32111 for supporting the battery 6. The positioning groove 3211 with a certain depth is provided on the top of the positioning component 32. The battery 6 is placed in the receiving groove, and the groove wall of the receiving groove limits the battery 6, so that the tray 3 can stably support the battery 6 and prevent the battery 6 from shaking.

[0040] In other embodiments, the positioning component 32 may be omitted, and the bottom of the tray 3 may directly serve as the receiving platform 32111 to support the battery 6.

[0041] In some embodiments, such as Figures 2 to 4 and Figure 8 As shown, the lifting platform 212 includes a connecting platform assembly 2121 and lifting plates 2122. Multiple lifting plates 2122 are provided. The driving end of the lifting drive mechanism 211 is connected to the connecting platform assembly 2121. Multiple lifting plates 2122 are spaced apart on the top of the connecting platform assembly 2121. By driving the connecting platform assembly 2121 to rise and fall through one lifting drive mechanism 211, all lifting plates 2122 can be driven to rise and fall. Each lifting plate 2122 lifts one battery 6, allowing the lifting platform 212 to lift multiple batteries 6 simultaneously. Correspondingly, as... Figure 5 and Figure 6As shown, each group of positioning components 32 includes positioning blocks 321 that are opposite to each other and spaced apart, with positioning grooves 3211 located on the top of the positioning blocks 321. Multiple groups of positioning components 32 are arranged in a row, with first clearance holes 31 extending along the arrangement direction of the multiple groups of positioning components 32 and located between the two positioning blocks 321 of each group of positioning components 32. The upper part of the connecting platform component 2121 is adapted to rise and fall through the first clearance holes 31. The two positioning blocks 321 of each group of positioning components 32 are opposite to each other and spaced apart, forming a clearance space between the two positioning blocks 321 for the upper part of the connecting platform component 2121 to rise above the positioning blocks 321, thus separating the bottom of the battery 6 from the tray 3, facilitating the forks 1 to extend from the bottom of the battery 6 and clamp the battery 6. The two ends of the battery 6 in the length direction are respectively located in the positioning grooves 3211 of the two positioning blocks 321 of each group.

[0042] In other embodiments, the lifting platform 212 includes a support plate connected to the drive end of the lifting drive mechanism 211, which drives the support plate to rise and fall to simultaneously lift multiple batteries 6.

[0043] like Figure 5 As shown, in some embodiments, the tray 3 has a long side and a wide side, and a plurality of positioning components 32 are spaced apart and arranged in rows along the length direction of the tray 3. A first clearance hole 31 extends along the length direction of the tray 3. A connecting platform assembly 2121 extends along the length direction of the tray 3, and a plurality of lifting plates 2122 are spaced apart along the length direction of the connecting platform assembly 2121. When the plurality of lifting plates 2122 are lifted upwards simultaneously, the batteries 6 above each row of positioning components 32 can be lifted upwards simultaneously.

[0044] In some alternative embodiments, such as Figure 8 As shown, each lifting device 2 includes two sets of opposing and spaced-apart lifting mechanisms 21. The lifting plates 2122 on the two sets of lifting platforms 212 are adapted to lift the battery 6 from both ends along its length. Two first clearance holes 31 are provided. The two sets of lifting mechanisms 21 in each lifting device 2 allow for simultaneous upward lifting of the battery 6 from both ends along its length, facilitating smooth lifting and preventing the battery 6 from swaying. The area between the two sets of lifting mechanisms 21 forms a clearance space, allowing the forks 1 to pass through. The two first clearance holes 31 allow the upper part of the connecting platform assembly 2121 of the two sets of lifting mechanisms 21 to pass through.

[0045] In other embodiments, each lifting device 2 may also be provided with one or more lifting mechanisms 21. When one lifting mechanism 21 is provided, the lifting platform 212 of the lifting mechanism 21 lifts the battery 6 upward from the middle area of ​​the bottom surface of the battery 6, thereby ensuring the smooth lifting of the battery 6. When three or more lifting mechanisms 21 are provided, the multiple lifting mechanisms 21 are arranged at intervals along the length direction of the bottom surface of the battery 6.

[0046] like Figure 2 and Figure 3 As shown, in some embodiments, the lifting platform 212 further includes a limiting component 2123, which is disposed on the lifting plate 2122. The limiting component 2123 is adapted to clamp and position the battery 6 from the side. The limiting component 2123 limits the battery 6, preventing the battery 6 from shaking during lifting or when it is lifted to its highest position. This ensures that the battery 6 is stably maintained at a predetermined height so that the forks 1 can move to the battery 6 to clamp it.

[0047] like Figure 3 As shown, in some embodiments, the lifting plate 2122 includes a first supporting portion 21221 and a second supporting portion 21222. The first supporting portion 21221 extends along the length direction of the first clearance hole 31, and the second supporting portion 21222 is perpendicular to the first supporting portion 21221. The limiting component 2123 includes two first limiting blocks 21231 and a second limiting block 21232. The two first limiting blocks 21231 are disposed opposite to each other at both ends of the first supporting portion 21221, and the second limiting block 21232 is disposed at the end of the second supporting portion 21222. The middle region of each positioning block 321 is broken to form a partition area. The bottom of the tray 3 is also provided with a second clearance hole 33, which is disposed at the bottom of the partition area and communicates with the first clearance hole 31. The first support portion 21221 extends along the length direction of the first clearance hole 31, passing through the tray 3. The second support portion 21222 passes through the tray 3 through the second clearance hole 33. The battery 6 includes a prismatic battery 6. Two first limiting blocks 21231 abut against the two large surfaces of the battery 6 to prevent the battery 6 from swaying along its thickness direction. The second limiting blocks 21232 on the two second support portions 21222 abut against the two sides of the battery 6 along its length direction to prevent the battery 6 from swaying along its length direction. The first limiting blocks 21231 and the second limiting blocks 21232 can effectively prevent the battery 6 from swaying, allowing the battery 6 to be smoothly lifted upwards and stably maintained at a predetermined height. Figure 6As shown, the central region of the positioning block 321 is broken to form a partition area, allowing the second supporting part 21222 and the second limiting block 21232 to rise and fall through the second clearance hole 33 and the partition area. The end of the second clearance hole 33 away from the first clearance hole 31 is located on the outer side of the side wall of the positioning block 321, facilitating the second limiting block 21232 to rise from the outside of the positioning block 321 and the battery 6 and abut against the side of the battery 6.

[0048] like Figure 6 and Figure 7 As shown, the second clearance hole 33 is located on one side of the first clearance hole 31 and is perpendicular to the first clearance hole 31. The second clearance holes 33 on the sides of the two first clearance holes 31 in each group are respectively located on opposite sides of the two first clearance holes 31, and the second clearance holes 33 on the sides of the two first clearance holes 31 in each group are arranged facing each other. Accordingly, as... Figure 3 As shown, each group of two opposing second support parts 21222 are arranged facing each other.

[0049] In some alternative embodiments, such as Figure 3 As shown, the top of the first limiting block 21231 is provided with a first guide slope 212311, and the top of the second limiting block 21232 is provided with a second guide slope 212321; the first guide slope 212311 slopes downward toward the first supporting part 21221, and the second guide slope 212321 slopes downward toward the second supporting part 21222. When the lifting plate 2122 rises, the bottom of the battery 6 can slide along the first guide slope 212311 and the second guide slope 212321 into the top surface of the first supporting part 21221 and the second supporting part 21222, which facilitates the accurate and rapid entry of the battery 6 into the supporting surface of the first supporting part 21221 and the second supporting part 21222, while preventing damage to the battery 6 from sharp corners.

[0050] Alternatively, in some embodiments, such as Figure 6 As shown, a third guide slope 3212 is provided on the positioning block 321 at the outer edge of the positioning groove 3211. The third guide slope 3212 slopes downward toward the inside of the positioning groove 3211. During the process of placing the battery 6 into the tray 3, the battery 6 slides into the positioning groove 3211 along the third guide slope 3212, which facilitates and quickly places the battery 6 into position, while preventing damage to the battery 6.

[0051] In some embodiments, such as Figure 5 and Figure 7 As shown, the tray 3 has multiple rows of positioning components 32, and each row of positioning components 32 holds a row of batteries 6. The number of lifting devices 2 corresponds to the number of rows of batteries 6. For example, in some embodiments, the tray 3 has two rows of positioning components 32, and the lifting devices 2 have two sets. Each set of positioning components 32 has two parallel and spaced first clearance holes 31.

[0052] like Figure 8 As shown, in some optional embodiments, the connecting platform assembly 2121 includes a first connecting plate 21211, a connecting column 21212, and a second connecting plate 21213 arranged sequentially from bottom to top. The driving end of the lifting drive mechanism 211 is connected to the first connecting plate 21211, and the connecting column 21212 is connected to the first connecting plate 21211 and the second connecting plate 21213. Multiple lifting plates 2122 are spaced apart on the top of the second connecting plate 21213. The connecting platform assembly 2121 includes the first connecting plate 21211, the connecting column 21212, and the second connecting plate 21213. The lifting drive mechanism 211 drives the first connecting plate 21211 to rise, which can simultaneously drive all the lifting plates 2122 to rise and fall, which is beneficial for simultaneously lifting multiple batteries 6. At the same time, it can simplify the structure of the lifting mechanism 21 and save costs.

[0053] For example, in some embodiments, two connecting posts 21212 are provided, the first connecting plate 21211 is rectangular, and the two connecting posts 21212 are located at both ends of the first connecting plate 21211. The driving end of the lifting drive mechanism 211 is connected to the middle position of the first connecting plate 21211. The middle region of the second connecting plate 21213 is thickened to ensure its structural strength and to ensure stable support of the battery 6. The first bearing part 21221 and the second bearing part 21222 are fixed to the top of the second connecting plate 21213.

[0054] like Figure 1 As shown, when the stationary system is working, the pallet 3 containing the battery 6 is transported to the stacker crane's picking position 5. The lifting drive mechanism 211 drives the connecting platform assembly 2121 and the lifting plate 2122 to rise. The second connecting plate 21213, the first bearing part 21221, and the first limiting block 21231 extend to the upper part of the pallet 3 through the first clearance hole 31. The second bearing part 21222 and the second limiting block 21232 extend to the upper part of the pallet 3 through the second clearance hole 33. The bottom of the battery 6 contacts the first limiting block 21231 and the second limiting block 21232, and slides into the first bearing part 21221 along the first guide ramp 212311 and the second guide ramp 212321. On the first and second support parts 21221 and 21222, the lifting drive mechanism 211 continues to drive the first support part 21221 and the second support part 21222 to rise, so that the battery 6 rises to a predetermined height, making the bottom of the battery 6 higher than the top of the pallet 3. The fork 1 moves from the area between the two lifting mechanisms 21 to below the battery 6. The clamping drive mechanism drives the clamping plate to clamp the battery 6. The lifting drive mechanism 211 drives the lifting plate 2122, the first limit block 21231 and the second limit block 21232 to descend. The limit block disengages from the battery 6. The fork 1 moves to outside the pallet 3 and places the battery 6 on the support leg 42 of the shelf 4, realizing the pallet-free static placement.
