[0101] Among them, referring to the above-mentioned steps 2→3, the control member 320 is first lowered and inserted between the two rollers 242 located on the upper side of the clamping jaws 240, so that the two rollers 242 move away from each other, and then the two clamping jaws 240 are rotated and the two clamping grooves 241 move away from each other, expanding the space between the two clamping grooves 241 for the rising battery 1 to enter between the two clamping grooves 241, and then the control member 320 is raised and leaves the two clamping jaws 240, so that the two clamping jaws 240 are close to each other, and the space between the two clamping grooves 241 is reduced, and the two clamping grooves 241 are used to clamp the battery 1 from both sides of the battery 1. Preferably, in order to actively bring the two clamping jaws 240 close to each other, a reset spring (not shown in the figure) is connected between the two clamping jaws 240. At this time, in the absence of external force, the elastic force of the reset spring is used to drive the two clamping jaws 240 to move close to each other, and then the elastic force is used to clamp the battery 1.

[0102] On the other hand, referring to the above-mentioned steps 6→7, during the process of the control member 320 descending, the two clamps 240 will be opened, so that the two clamps 240 release the clamping force on the battery 1. At the same time, the lifting component 400 can drive the released battery 1 to descend and away from the two clamps 240, so as to facilitate the use of the discharge component 600 to take out the material in the subsequent step 8.

[0103] In step 3 above, refer to Figure 4, the two clamping jaws 240 are brought close to each other, so that the battery 1 can be clamped between the two opposite clamping grooves 241. In the process of clamping the lithium battery 1, if the range limited by the two clamping grooves 241 is slightly larger than the current size of the battery 1, it is easy to cause the battery 1 to fall during the flipping process; and if the range limited by the two clamping grooves 241 is slightly smaller than the current size of the battery 1, it is easy to generate unbalanced pressure on the local area of ​​the outer wall of the battery 1, causing damage or dents on the outer wall; Therefore, in some embodiments, the clamping groove 241 is fixedly connected with a deformable rubber sac 250, three inner cavities 251 are arranged inside the rubber sac 250, a diaphragm 252 is arranged between two adjacent inner cavities 251, the diaphragm 252 is provided with a plurality of guide holes 253, the middle part of the rubber sac 250 is arc-shaped, and the two ends are hook-shaped, the inner cavity 251 is filled with a non-Newtonian fluid, and an elastic damping pad surface 260 is arranged on the opposite side of the rubber sac 250, and a damping structure 261 is arranged on the surface of the damping pad surface 260. The clamping space defined by the clamping grooves 241 of the two clamping jaws 240 meets the preset size of the battery 1, and the rubber sac 250 in the clamping grooves 241 is used to compensate for the error problem between different products. Therefore, the restricted clamping space between the two rubber sacs 250 is small. Specifically, refer to Fig. 9 When the battery 1 is larger in size, the two sides of the rubber capsule 250 are squeezed, causing the non-Newtonian fluid in the inner cavity 251 at both ends to flow to the middle inner cavity 251, expanding the curvature of the rubber capsule 250 to match the actual outer circumference of the product; refer to Fig.10 When the battery 1 is small in size, the middle of the rubber bladder 250 is pressurized to force the non-Newtonian fluid in the middle inner cavity 251 to flow to the inner cavities 251 at both ends, thereby reducing the curvature of the rubber bladder 250 to match the actual outer circumference of the product. It should be emphasized that since the mold of the battery 1 is fixed during the processing, the error in its size is extremely small. The rubber bladder 250 in this embodiment causes the pressure of each part of the outer circumferential wall of the battery 1 to be consistent through slight deformation, thereby ensuring the integrity of the outer surface of the battery 1. In addition, the damping pad surface 260 is in contact with the outer wall of the battery 1 to further increase the friction between the clamping assembly 200 and the battery 1. Figure 8 The damping structure 261 is a plurality of damping strips arranged on the damping pad surface 260 . The damping strips are arranged along the extending direction of the damping pad surface 260 , and the plurality of damping strips are arranged at intervals.

[0104] Reference Figure 4In some embodiments, the lifting assembly 400 includes a lifting fixed seat 410, a lifting support plate 420 and a connecting rod 430. The lifting fixed seat 410 is fixedly connected to the lower side of the connecting plate 141. The lifting fixed seat 410 can and can only move along a circular track around the outer wall of the bracket 100. The lifting fixed seat 410 is provided with a second slide rail 411 arranged in a vertical direction; the lifting support plate 420 is slidably connected to the second slide rail 411, and a receiving groove 421 is provided on the upper surface of the lifting support plate 420. The receiving groove 421 is open to the outside, and the circumferential angle of the receiving groove 421 is less than or equal to 180°. The shape of the receiving groove 421 matches that of the cup holder 700; a third slider 431 is provided at one end of the connecting rod 430, and the other end is fixedly connected to the lifting support plate 420, and the third slider 431 is slidably matched with the third track 130. The position of the lifting fixing seat 410 is fixed, so that the entire lifting assembly 400 can move to different positions as the connecting plate 141 rotates, and cooperate with the clamping assembly 200 to perform different processes at different positions.

[0105] Specifically, refer to Figure 5 , referring to the above step 1→step 2, the feeding assembly 500 inputs the cup holder 700 with the battery 1 into the receiving groove 421 of the lifting support plate 420, and then brings the battery 1 between the two clamping claws 240 through the liftable lifting support plate 420, and cooperates with the clamping assembly 200 to clamp the battery 1;

[0106] On the other hand, referring to Figure 6 , referring to the above step 3 → step 4, before the battery 1 is flipped 180° by the clamping assembly 200, the lifting support plate 420 supporting the cup holder 700 is lowered to a position where it does not interfere with the battery 1, so that in the subsequent step 5, the battery 1 can be prevented from colliding with the cup holder 700 during the flipping process;

[0107] On the other hand, referring to the above step 6 → step 7, the descending lifting plate 420 removes the battery 1 from the clamping range of the clamping assembly 200, and then in the subsequent step 8, the cup holder 700 in the lifting assembly 400 can be removed by the discharge assembly 600.

[0108] In some embodiments, reference Figure 2The feeding assembly 500 includes a feeding conveyor belt 510, a feeding turntable 520 and a feeding annular plate 530.

The plurality of feeding troughs 521 are equidistantly arranged around the rotation center of the feeding turntable 520. The circumferential angle of the feeding troughs 521 is smaller than the receiving groove 421. The feeding turntable 520 can rotate so that the positions of the feeding troughs 521 and the receiving groove 421 correspond to each other. The rotation direction of the material turntable 520 is opposite to that of the rotating cylinder 140; the feed annular plate 530 is arranged around the outer side of the feed turntable 520, and the feed annular plate 530 allows the cup holder 700 to slide, and the feed annular plate 530 has a first input end and a first output end, and the first input end and the discharge end of the feed conveyor belt 510 are correspondingly arranged; wherein, when the lifting support plate 420 moves to the first output end, the lifting support plate 420 is located below the feed annular plate 530 and corresponds to the position of one of the feed troughs 521.

[0109] In actual use, the feed conveyor belt 510 is used to convey the cup holder 700, so that the cup holder 700 loaded with the battery 1 can enter the transfer unit of the bracket 100, wherein the feed turntable 520 is pivoted so that the multiple feed slots 521 loaded with the cup holder 700 can correspond to different receiving slots 421 respectively, and the cup holder 700 can be taken away by the receiving slot 421 through the opposite rotation direction and the feed slot 521 with a circumferential angle smaller than the receiving slot 421. Furthermore, due to the small circumferential angle, the cup holder 700 located on the feed annular plate 530 is easy to fall out. In order to prevent the battery 1 from falling out, the feed assembly 500 is further provided with a feed fence 540 along the extension direction of the feed annular plate 530. The feed fence 540 is arranged on the outside of the cup holder 700, and can limit the cup holder 700 when the cup holder 700 deviates outward to prevent the cup holder 700 from falling.

[0110] In some embodiments, reference Figure 2The discharging assembly 600 includes a discharging conveyor belt 610, a discharging turntable 620 and a discharging annular plate 630. The discharging turntable 620 is pivotally arranged at the feeding end of the discharging conveyor belt 610. The discharging turntable 620 is provided with a plurality of discharging slots 621. The plurality of discharging slots 621 are arranged equidistantly around the rotation center of the discharging turntable 620. The discharging slot 621 is provided with a discharging side 6211. The discharging side 6211 is used to take out the cup holder 700 from the receiving slot 421 and feed the cup holder 700 into the discharging conveyor belt 610. The discharging annular plate 630 is provided with a plurality of discharging slots 621. 30 is arranged around the outer side of the discharge turntable 620, the discharge annular plate 630 is provided for the cup holder 700 to slide, the discharge annular plate 630 has a second input end and a second output end, and the second output end is arranged corresponding to the feeding end of the discharge conveyor belt 610; wherein, when the lifting support plate 420 moves to the second input end, the lifting plate is located below the discharge annular plate 630 and is arranged corresponding to one of the discharge grooves 621, the discharge turntable 620 can rotate so that the material-pickup side 6211 abuts against the cup holder 700, and the cup holder 700 is pushed into the discharge annular plate 630.

[0111] After the battery 1 is flipped 180°, it is transported by the transfer unit to a position corresponding to the discharge turntable 620. The discharge turntable 620 pivots so that the multiple discharge slots 621 loaded with the cup holder 700 correspond to the positions of different receiving slots 421. Specifically, the picking side 6211 in the discharge slot 621 can directly abut against the side wall of the cup holder 700, and pick the cup holder 700 onto the discharge ring plate 630, so that the cup holder 700 moves along the extension direction of the discharge ring plate 630, and finally moves to the discharge conveyor belt 610, and is transported to the next process by the discharge conveyor belt 610. In order to prevent the battery 1 from falling out, the discharge assembly 600 is further provided with a discharge fence 640 along the extension direction of the discharge ring plate 630. The discharge fence 640 is arranged on the outside of the cup holder 700, and can limit the cup holder 700 when it deviates outward to prevent the cup holder 700 from falling.

[0112] As can be seen from the above, the driving gear 142 is driven to pivot by the rotating motor 810. Specifically, referring to Fig.11The rotating motor 810 is fixedly connected to a driving wheel 820, which is coaxial with the driving gear 142 and rotates synchronously. The automatic conveying device also includes two steering wheels 830, a feed wheel 850 and a discharge wheel 840. The feed wheel 850 is coaxial with the feed turntable 520 and rotates synchronously. The discharge wheel 840 is coaxial with the discharge turntable 620 and rotates synchronously. A transmission belt 860 is wound around the two steering wheels 830, the feed wheel 850 and the discharge wheel 840. The wheel 830, the feed wheel 850 and the discharge wheel 840 are located on the inner side of the transmission belt 860 and are in transmission coordination with each other. The driving wheel 820 is located on the outer side of the transmission belt 860 and is in transmission coordination with the transmission belt 860, so that the rotation directions of the driving wheel 820, the feed wheel 850 and the discharge wheel 840 are opposite, so that the feed turntable 520 and the discharge turntable 620 have the same direction of rotation. At the same time, the transfer unit (or rotating drum 140), the feed turntable 520, and the discharge turntable 620 have opposite directions of rotation.
