Description

Technical Field

[0001] This invention relates to the field of battery technology, and more particularly to a battery flipping device. Background Technology

[0002] When inserting individual cells into the pack, an inverted insertion method is used. Specifically, the individual cells are arranged with one end of the terminal placed on a platform, and then the pack housing is inverted on top of the arranged individual cells to insert them into the pack. After insertion, the pack housing and the individual cells inside need to be flipped over to facilitate the subsequent assembly and soldering of the busbar assembly.

[0034] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

They are only for the convenience of describing this invention and simplifying the description, and 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. Therefore, they should not be construed as limitations on this invention.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0037] Please refer to Figures 1 to 14 A battery flipping device includes a side support frame 11, a flipping clamp 2, and a transfer assembly 3. The two side supports 11 are arranged in a mirror image, as shown below. Figure 1 and Figure 2 As shown, the two side supports 11 are equipped with two top crossbeams 12, which are connected to form a gantry frame 1 to maintain the stability of the battery flipping device structure. Further, as... Figure 2 As shown, a vertically movable flipping assembly 13 is disposed on the side support 11. The flipping assembly 13 includes a drive plate 131 slidably mounted on the side support 11 in the vertical direction via a slide rail slider assembly. A turntable 132 is rotatably mounted on the drive plate 131. One turntable 132 on the drive plate 131 is the driving member, and the other turntable 132 on the drive plate 131 is the driven member. A drive screw 133 extending in the vertical direction is rotatably mounted on the side support 11 and is driven to rotate by a first motor 134 disposed on the side support 11. The drive plate 131 is threadedly connected to the drive screw 133 to realize the vertical movement of the flipping assembly 13. A flipping clamp 2 is disposed between two side uprights 11. The flipping clamp 2 is assembled with a flipping assembly 13, and the flipping clamp 2 can be flipped under the action of the flipping assembly 13. The transfer assembly 3 is used to carry and transfer a pallet and a battery pack b disposed on the pallet. The pallet includes a stacked mother pallet d and a daughter pallet a, and the battery pack b is disposed on the daughter pallet a. Optionally, the transfer assembly 3 is an AGV trolley.

[0038] In this embodiment, the flipping clamp 2 includes a square tube frame 21, on which a receiving hole 22 is provided for accommodating the sub-tray a and the battery pack b. The square tube frame 21 is provided with a first clamping mechanism 23 for fixing the sub-tray a and a second clamping mechanism 24 for fixing the battery pack b. The second clamping mechanism 24 can act on the PACK housing c, causing it to tend to move towards the sub-tray a. Optionally, as... Figure 3 , Figure 4 and Figure 6 As shown, in some embodiments, the square tube frame 21 is equipped with an adapter plate 211 corresponding to the turntable 132, and the adapter plate 211 is fixedly assembled to the corresponding turntable 132. In use, the turntable 132, as the active component, is driven to rotate by a second motor 135 mounted on the drive plate 131, thereby realizing the flipping of the flipping fixture 2, and further realizing the flipping of the sub-tray a and the battery pack b positioned on the flipping fixture 2.

[0039] In summary, when using this battery flipping device, the transfer component 3 first transfers the tray and the battery pack b on the tray to below the flipping clamp 2. Under the action of the flipping component 13, the flipping clamp 2 moves vertically downwards and approaches the battery pack b. Then, the first clamping mechanism 23 acts on the sub-tray a, and the second clamping mechanism 24 acts on the battery pack b. Under the action of the flipping component 13, the flipping clamp 2 moves vertically upwards. At this time, the sub-tray a separates from the mother tray d. The sub-tray a and the battery pack b move upwards synchronously with the flipping clamp 2. The AGV trolley then carries the mother tray d away. After the flipping fixture 2 moves to a certain height, it flips 180° under the action of the flipping component 13, realizing the flipping of the sub-pallet a and the battery pack b (before the flip, the sub-pallet a is below and the battery pack b is above; after the flip, the battery pack b is below and the sub-pallet a is above). Finally, the flipping fixture 2 moves downward in the vertical direction under the action of the flipping component 13. The AGV trolley carrying the battery pack b and the sub-pallet a arrives below the flipping fixture 2. After the battery pack b and the sub-pallet a come into contact with the AGV trolley, the first clamping mechanism 23 disengages from the sub-pallet a, and the second clamping mechanism 24 disengages from the battery pack b.

[0040] During this process, the second clamping mechanism 24 can act on the PACK box c, causing it to tend to move toward the sub-tray a. In other words, the second clamping mechanism 24 can apply force to the PACK box c, so that it works with the sub-tray a to press and fix the individual cells inside the PACK box c. This can prevent the individual cells from shifting due to gravity during the subsequent flipping process, thus ensuring product quality.

[0041] like Figure 6 and Figure 7 As shown, the receiving hole 22 is provided with adjustment brackets 25 on both sides in the first direction X. On one side of the adjustment bracket 25 in the thickness direction of the battery pack b, a fixed plate 251 is provided, and on the other side, a floating plate 252 is provided. The fixed plate 251 is fixedly connected to the adjustment bracket 25. A guide post 253 is provided on the floating plate 252. The guide post 253 passes through the fixed plate 251 and is slidably connected to it. The axial direction of the guide post 253 is perpendicular to the floating plate 252. An adjustment cylinder 254 is provided on the fixed plate 251 for driving the floating plate 252 to move closer to or away from the adjustment bracket 25 along the axial direction of the guide post 253.

[0042] In this embodiment, the first clamping mechanism 23 and the second clamping mechanism 24 are both mounted on the floating plate 252. This allows the positions of the first clamping mechanism 23 and the second clamping mechanism 24 to be adjusted in the thickness direction of the square tube frame 21, that is, in the thickness direction of the battery pack b, so as to better cooperate with the sub-tray a and the battery pack b.

[0043] Furthermore, such as Figure 7As shown, the regulating cylinder 254 is equipped with a first limiting plate 2541, and the guide column 253 is equipped with a second limiting plate 2531. A floating spring 255 is pressed between the first limiting plate 2541 and the second limiting plate 2531. The floating spring 255 facilitates the reset of the floating plate 252.

[0044] The second limiting plate 2531 is equipped with a limiting pin. When the second limiting plate 2531 moves toward the first limiting plate 2541, the first limiting plate 2541 is on the movement path of the limiting pin.

[0045] like Figure 6 , Figure 8 and Figure 9 As shown, the first clamping mechanism 23 includes a first base plate 231 and a first mounting plate 232, wherein: the first mounting plate 232 is movably mounted on the first base plate 231 along the first direction X via a slide rail slider assembly; an extension plate 233 is disposed on the first mounting plate 232; a first mounting block 2331 is disposed on the extension plate 233; a first mounting hole a2 corresponding to the first mounting block 2331 is disposed on the sub-tray a; the first mounting block 2331 can move with the first mounting plate 232 to engage or disengage from the first mounting hole a2. Figure 5 As shown, a positioning seat a1 is provided on the sub-tray a, and a first assembly hole a2 is provided on the positioning seat a1. In this embodiment, four positioning seats a1 are configured on the sub-tray a, and correspondingly, four first clamping mechanisms 23 are assembled on the square tube frame 21, which cooperate with the four positioning seats a1 one by one to limit and fix the sub-tray a.

[0046] It should be noted that the positioning seat a1 here can be understood as being integrated with the sub-tray a, as part of the structure of the sub-tray a.

[0047] Optionally, the first mounting plate 232 is driven to move along the first direction X by a first cylinder 2311 disposed on the first base plate 231.

[0048] like Figure 3 and 5 As shown, the thickness direction of battery pack b is defined as the second direction Y. The direction in which PACK body c moves toward sub-tray a is parallel to the second direction Y. The first direction X is perpendicular to the second direction Y. The first clamping mechanism 23 also includes a first vertical plate 234, which is fixedly installed on the first mounting plate 232 and extends along the second direction Y. A first pressure plate 235 is adjustablely arranged on the first vertical plate 234 along the second direction Y. A first pressure block 2351 is arranged on the first pressure plate 235. A first positioning surface a3 corresponding to the first pressure block 2351 is arranged on the sub-tray a. The first pressure block 2351 can fit or detach from the first positioning surface a3 along the second direction Y. The first positioning surface a3 is located between the first mounting block 2331 and the first pressure block 2351. Figure 5 As shown, the flipping fixture 2 is assembled with sub-tray a and battery pack b, and is in the state before flipping. At this time, the first pressing block 2351 cooperates with the first positioning surface a3 and the first mounting block 2331 cooperates with the first mounting hole a2. The first pressing block 2351 and the first mounting block 2331 can be relatively close to each other in the second direction Y to clamp the positioning seat a1, so that the sub-tray a is stable and does not shift during the flipping process of the flipping fixture 2.

[0049] Optionally, the first pressure plate 235 is slidably connected to the first vertical plate 234 via a slide rail slider assembly, and is driven to move along the second direction Y by a second cylinder 2341 disposed on the first mounting plate 232 or the first vertical plate 234. In this embodiment, the second cylinder 2341 is disposed on the first vertical plate 234.

[0050] like Figure 8 and Figure 9 As shown, the first base plate 231 is provided with a first positioning hole 2312 and a second positioning hole 2313. In the first direction X, the second positioning hole 2313 is closer to the sub-tray a than the first positioning hole 2312. A first mounting plate 232 is adjustablely provided with a first pin 2321 along the second direction Y. When the first pin 2321 is inserted into the first positioning hole 2312, the first mounting block 2331 is in an unlocked state. When the first pin 2321 is inserted into the second positioning hole 2313, the first mounting block 2331 is in a locked state. Optionally, the first pin 2321 passes through the first mounting plate 232. A first shaft bracket 2322 is provided on the first mounting plate 232. A third cylinder 2323 is provided on the first shaft bracket 2322 for driving the first pin 2321 to move along the second direction Y. The first pin 2321 here cooperates with the first positioning hole 2312 and the second positioning hole 2313 respectively to keep the relative position of the first mounting plate 232 and the first base plate 231 fixed in the unlocked and locked states, ensuring that the first mounting block 2331 does not disengage from the first assembly hole a2 in the locked state, thereby improving safety.

[0051] like Figure 8 and Figure 9As shown, the first pressure plate 235 is provided with a third positioning hole 2352, and the first vertical plate 234 is provided with a second pin 2342. When the second pin 2342 is inserted into the third positioning hole 2352, the first pressure block 2351 is in a locked state. Optionally, in this embodiment, the first vertical plate 234 is provided with a second shaft bracket 2343, and the second shaft bracket 2343 is provided with a fourth cylinder 2344. The second pin 2342 passes through the first vertical plate 234, and the fourth cylinder 2344 is used to drive the second pin 2342 to insert or disengage from the third positioning hole 2352. In use, when the first pressure plate 235 moves along the second direction Y to make the first pressure block 2351 fit against the first positioning surface a3, the second pin 2342 is inserted into the third positioning hole 2352 to limit the first pressure plate 235, preventing the first pressure plate 235 from retracting and causing the first pressure block 2351 to disengage from the first positioning surface a3.

[0052] like Figure 3 and Figure 5 As shown, in this embodiment, a second positioning surface a4 is provided on the positioning base a1. The second positioning surface a4 is located on the movement path of the first pressing block 2351 along the first direction X towards the battery pack b. In this way, the second positioning surface a4 and the first pressing block 2351 cooperate with each other to limit the sub-tray a in the first direction X, preventing the sub-tray a from shifting in the first direction X during the flipping process.

[0053] Furthermore, such as Figure 3 , Figures 10 to 14 As shown, the second clamping mechanism 24 includes a second base plate 241 and a second vertical plate 242. The second vertical plate 242 is fixedly installed on the second base plate 241 and extends along the second direction Y. A transition strip 243 is movably provided on the second vertical plate 242 along the second direction Y. A positioning rod 244 is movably provided on the transition strip 243 along the first direction X. A limiting block 245 is provided at one end of the positioning rod 244 facing the battery pack b. A first limiting surface 2451, a second limiting surface 2452, and a third limiting surface 2453 are provided on the limiting block 245. The three are perpendicular to each other. The lifting lug c1 of the PACK box c is in the space defined by the first limiting surface 2451, the second limiting surface 2452, and the third limiting surface 2453. The first limiting surface 2451 acts on the lifting lug c1 so that the PACK box c has a tendency to move towards the sub-tray a.

[0054] Optionally, the transition bar 243 is slidably connected to the second vertical plate 242 via a slide rail slider assembly. A fifth cylinder 2421 is mounted on the second vertical plate 242, driving the transition bar 243 to move along the second direction Y. Specifically, the fifth cylinder 2421 is mounted on the top of the second vertical plate 242 via a cylinder bracket 2422. A first extension block 246 is mounted on the positioning rod 244, and a connecting block 2461 is fixedly mounted on the first extension block 246. The fifth cylinder 2421 is connected to the connecting block 2461, and acts on the transition bar 243 through the connecting block 2461 and the first extension block 246. In this embodiment, the positioning rod 244 is slidably connected to the transition bar 243 via a slide rail slider assembly. The positioning rod 244 is driven by a sixth cylinder 2431 mounted on the transition bar 243, thereby allowing the limiting block 245 to move closer to or further away from the lifting lug c1 along the first direction X. The fifth cylinder 2421 acts on the transition bar 243, so that the limiting block 245 can approach or move away from the lug c1 in the second direction Y. Specifically, the first limiting surface 2451 can abut or disengage from the lug c1 in the second direction Y.

[0055] In this embodiment, the second limiting surface 2452 is used to limit the lifting lug c1 in the first direction X, and the third limiting surface 2453 is used to limit the lifting lug c1 in the third direction, thereby ensuring the stability of the PACK box c during the flipping process.

[0056] Furthermore, a follower push block 2462 is disposed on the transition strip 243, and the follower push block 2462 can follow the transition strip 243 to move along the second direction Y; a stop push block 2425 is disposed on the second vertical plate 242, and when the second clamping mechanism 24 is in the locked state, the stop push block 2425 is used to limit the follower push block 2462 along the path away from the battery pack b in the second direction Y. Optionally, in this embodiment, the follower push block 2462 is disposed on the first extension block 246, and the first extension block 246 can pass through the second vertical plate 242 through the clearance hole 2423 disposed on the second vertical plate 242, so that the second vertical plate 242 is located between the follower push block 2462 and the connecting block 2461. A seventh cylinder 2424 is configured on the second vertical plate 242. A follower pusher block 2462 is slidably mounted on the second vertical plate 242 via a slide rail slider assembly. The seventh cylinder 2424 acts on the follower pusher block 2462 to allow it to slide relative to the second vertical plate 242 along the first direction X. With this configuration, the follower pusher block 2462 and the anti-reverse pusher block 2425 cooperate to keep the second clamping mechanism 24 in a stable locked state, preventing the PACK box c from shifting during the flipping process. In particular, it prevents the first limiting surface 2451 from disengaging from the lifting lug c1 or from becoming loose. This ensures that the movement trend of the PACK box c towards the sub-tray a along the second direction Y does not disappear and remains stable during the flipping process. As a result, during the flipping process, the PACK box c, together with the sub-tray a, presses and fixes the individual batteries inside the PACK box c, preventing the individual batteries from shifting due to gravity during the flipping process.

[0057] like Figure 11 and Figure 12 As shown, the follower push block 2462 is equipped with a first locking slope 2463, and the anti-reverse push block 2425 is equipped with a second locking slope 2426 corresponding to the first locking slope 2463. When the second clamping mechanism 24 is in the locked state, the first locking slope 2463 and the second locking slope 2426 are in contact. The slope is designed to limit the follower push block 2462 within a certain stroke range by the anti-reverse push block 2425. Specifically, the position of the anti-reverse push block 2425 is adjusted in the first direction X, and the first locking slope 2463 and the second locking slope 2426 cooperate to change the extreme position of the follower push block 2462 in the second direction Y. This is reflected in the assembly of the first limiting surface 2451 and the lifting lug c1, which makes the pressure applied by the first limiting surface 2451 on the lifting lug c1 adjustable to adapt to the flipping operation of different models of battery packs b.

[0058] like Figure 3 , Figure 4 and Figure 6 As shown, in this embodiment, the rotating shaft e of the flipping fixture 2, which is flipped by the flipping component 13, is parallel to the first direction X.
