At the same time, two rollers 242 located on the upper side or the lower side are a group, and the two rollers 242 in the same group are arranged oppositely. The lower end of the control member 320 can be inserted between the two rollers 242 in the same group, so that the two rollers 242 move away from each other on the horizontal plane.

[0101] Among them, referring to the above step 2→step 3, first, the control member 320 descends and is inserted between the two rollers 242 on the upper side of the jaws 240, so that the two rollers 242 move away from each other, and then the two jaws 240 rotate, 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. Then, the control member 320 rises and leaves the two jaws 240, so that the two jaws 240 approach each other, narrowing the space between the two clamping grooves 241, and clamping the battery 1 from both sides of the battery 1 by using the two clamping grooves 241. Preferably, in order to make the two jaws 240 actively approach each other, a return spring (not shown in the figure) is connected between the two jaws 240. At this time, without the action of external force, the elastic force of the return spring is used to drive the two jaws 240 to approach each other, and then the battery 1 is clamped by using the elastic force.

[0102] On the other hand, referring to the above step 6→step 7, during the descending process of the control member 320, the two jaws 240 will be opened, so that the two jaws 240 release the clamping force on the battery 1. At the same time, the lifting assembly 400 can drive the released battery 1 to descend and move away from the two jaws 240, facilitating the subsequent step 8 to pick up the material by using the discharging assembly 600.

[0103] In the above step 3, referring to Figure 4, by making the two jaws 240 approach each other, the battery 1 can be clamped between two opposite clamping grooves 241. Among them, during the clamping process of the lithium battery 1, if the range restricted by the two clamping grooves 241 is slightly larger than the current size of the battery 1, it is easy for the battery 1 to fall during the flipping process; if the range restricted 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 a local area of the outer wall of the battery 1, resulting in easy damage or depression on its exterior; for this reason, in some embodiments, a deformable rubber bladder 250 is fixedly connected to the clamping groove 241. Three inner cavities 251 are arranged inside the rubber bladder 250, a diaphragm 252 is arranged between two adjacent inner cavities 251, and the diaphragm 252 is provided with a plurality of flow guiding holes 253. The middle part of the rubber bladder 250 is arc-shaped and both ends are hook-shaped. The inner cavity 251 is filled with non-Newtonian fluid. An elastic damping pad surface 260 is arranged on the opposite side of the rubber bladder 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 jaws 240 conforms to the preset size of the battery 1, and the rubber bladder 250 in the clamping groove 241 is used to make up for the error problem between different products. Therefore, the clamping space restricted between the two rubber bladders 250 is small. Specifically, referring to Figure 9 , when the size of the battery 1 is large, it will squeeze both sides of the rubber bladder 250, prompting the non-Newtonian fluid in the inner cavities 251 at both ends to flow towards the middle inner cavity 251, expanding the arc of the rubber bladder 250 to fit the actual outer circumference of the product; referring to Figure 10 , when the size of the battery 1 is small, it will apply pressure to the middle part of the rubber bladder 250, prompting the non-Newtonian fluid in the middle inner cavity 251 to flow towards the inner cavities 251 at both ends, reducing the arc of the rubber bladder 250 to fit the actual outer circumference of the product. It should be emphasized that since the mold during the processing of the battery 1 is fixed, the error in its size is extremely small. The rubber bladder 250 in this embodiment undergoes a slight deformation to make the pressure on each part of the outer peripheral wall of the battery 1 tend to be consistent, ensuring the integrity of the outer surface of the battery 1. In addition, the damping pad surface 260 further improves the friction force between the clamping assembly 200 and the battery 1 by abutting and fitting with the outer wall of the battery 1. Referring to Figure 8 , the damping structure 261 is a plurality of damping strips arranged on the damping pad surface 260, and 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] Referring to Figure 4, in some embodiments, the lifting assembly 400 includes a lifting fixed seat 410, a lifting tray 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 trajectory around the outer wall of the bracket 100. The lifting fixed seat 410 is provided with a second slide rail 411 arranged in the vertical direction; the lifting tray 420 is slidably connected to the second slide rail 411. The upper surface of the lifting tray 420 is provided with a receiving groove 421. One side of the receiving groove 421 facing outward is open, and the circumferential angle of the receiving groove 421 is less than or equal to 180°. The shape of the receiving groove 421 matches the shape of the cup holder 700; one end of the connecting rod 430 is provided with a third slider 431, and the other end is fixedly connected to the lifting tray 420. The third slider 431 is slidably matched with the third track 130. The position of the lifting fixed 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, referring to Figure 5 , referring to the above steps 1→step 2, the feeding assembly 500 inputs the cup holder 700 with the battery 1 into the receiving groove 421 of the lifting tray 420, and then brings the battery 1 between the two jaws 240 through the liftable lifting tray 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 steps 3→step 4, before the battery 1 is flipped 180° by the clamping assembly 200, the lifting tray 420 supporting the cup holder 700 is lowered to a position where there is no interference with the battery 1, so that in the subsequent step 5, it is possible to avoid the collision between the battery 1 flipping process and the cup holder 700;

[0107] On the other hand, referring to the above steps 6→step 7, the lowered lifting tray 420 disengages the battery 1 from the clamping range of the clamping assembly 200, so that in the subsequent step 8, the cup holder 700 in the lifting assembly 400 can be taken away by the discharging assembly 600.

[0108] In some embodiments, referring to Figure 2, the feeding assembly 500 includes a feeding conveyor belt 510, a feeding turntable 520 and a feeding annular plate 530. The feeding turntable 520 is pivotally arranged at the discharging end of the feeding conveyor belt 510. The feeding turntable 520 is provided with a plurality of feeding grooves 521. The plurality of feeding grooves 521 are arranged at equal intervals around the rotation center of the feeding turntable 520. The circumferential angle of the feeding groove 521 is smaller than that of the receiving groove 421. Among them, the feeding turntable 520 can rotate so that the feeding groove 521 corresponds to the receiving groove 421 in position. The rotation direction of the feeding turntable 520 is opposite to the rotation direction of the rotating cylinder 140. The feeding annular plate 530 is arranged around the outer side of the feeding turntable 520. The feeding annular plate 530 allows the cup holder 700 to slide. The feeding annular plate 530 has a first input end and a first output end. The first input end corresponds to the discharging end of the feeding conveyor belt 510. Among them, when the lifting support plate 420 moves to the first output end, the lifting support plate 420 is located below the feeding annular plate 530 and corresponds to one of the feeding grooves 521 in position.

[0109] In actual use, the feeding 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. Among them, through pivoting, the plurality of feeding grooves 521 loaded with the cup holder 700 on the feeding turntable 520 can respectively correspond to different receiving grooves 421. Through the opposite rotation direction and the feeding groove 521 with a circumferential angle smaller than that of the receiving groove 421, the cup holder 700 can be taken away by the receiving groove 421. Further, due to the smaller circumferential angle, the cup holder 700 located on the feeding annular plate 530 is likely to come out. In order to prevent the battery 1 from coming out, along the extending direction of the feeding annular plate 530, the feeding assembly 500 is further provided with a feeding fence 540. The feeding fence 540 is arranged outside the cup holder 700 and can limit the cup holder 700 when the cup holder 700 deflects outwards to prevent the cup holder 700 from falling.

[0110] In some embodiments, referring to Figure 2, the 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 grooves 621. The plurality of discharging grooves 621 are arranged at equal intervals around the rotation center of the discharging turntable 620. The discharging groove 621 is provided with a material pushing side 6211. The material pushing side 6211 is used to take out the cup holder 700 from the receiving groove 421 and send the cup holder 700 to the discharging conveyor belt 610. The discharging annular plate 630 is arranged around the outer side of the discharging turntable 620. The discharging annular plate 630 allows the cup holder 700 to slide. The discharging annular plate 630 has a second input end and a second output end. The second output end is correspondingly arranged with the feeding end of the discharging conveyor belt 610. Wherein, when the lifting support plate 420 moves to the second input end, the lifting plate is located below the discharging annular plate 630 and is correspondingly arranged with one of the discharging grooves 621. The discharging turntable 620 can rotate so that the material pushing side 6211 abuts against the cup holder 700 and pushes the cup holder 700 into the discharging annular plate 630.

[0111] After the battery 1 is flipped 180°, it is transported to a position corresponding to the discharging turntable 620 under the transportation of the transfer unit. The discharging turntable 620 is pivoted so that the plurality of discharging grooves 621 loaded with the cup holder 700 correspond to different receiving grooves 421. Specifically, the material pushing side 6211 in the discharging groove 621 can directly abut against the side wall of the cup holder 700 and push the cup holder 700 into the discharging annular plate 630, and make the cup holder 700 move along the extending direction of the discharging annular plate 630 and finally move to the discharging conveyor belt 610, and is transported by the discharging conveyor belt 610 to the next process. Wherein, in order to prevent the battery 1 from falling out, along the extending direction of the discharging annular plate 630, the discharging assembly 600 is further provided with a discharging fence 640. The discharging fence 640 is arranged outside the cup holder 700 and can limit the cup holder 700 when the cup holder 700 deviates outwards to prevent the cup holder 700 from falling.

[0112] As can be seen from the above, the driving gear 142 is pivotally driven by the rotating motor 810. Specifically, refer to Figure 11, a rotating motor 810 is fixedly connected with a driving wheel 820. The driving wheel 820 and a driving gear 142 are coaxial and rotate synchronously. The automatic conveying device further includes two steering wheels 830, a feeding wheel 850 and a discharging wheel 840. The feeding wheel 850 and a feeding turntable 520 are coaxial and rotate synchronously. The discharging wheel 840 and a discharging turntable 620 are coaxial and rotate synchronously. A transmission belt 860 is wound around the two steering wheels 830, the feeding wheel 850 and the discharging wheel 840. The two steering wheels 830, the feeding wheel 850 and the discharging wheel 840 are located inside the transmission belt 860 and are in transmission cooperation. The driving wheel 820 is located outside the transmission belt 860 and is in transmission cooperation with the transmission belt 860. Thus, the rotation directions of the driving wheel 820, the feeding wheel 850 and the discharging wheel 840 are all opposite, realizing that the rotation directions of the feeding turntable 520 and the discharging turntable 620 are the same. At the same time, the rotation directions of the transfer unit (or the rotating cylinder 140), the feeding turntable 520 and the discharging turntable 620 are opposite.
