[0035] 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 the present application belongs. The terminology used in the description of the present application herein only for the purpose of describing specific embodiments of the present application, and is not intended to limit the present application.

[0036] Reference should be made to Figures 1 to 5The battery piece overturning device provided in the embodiments of the present application comprises an overturning mechanism 1, a first conveying mechanism 2 and a second conveying mechanism 3. The overturning mechanism 1 comprises a base 11 and an overturning piece 12. The overturning piece 12 is rotatably connected to the base 11 through a rotating shaft 13. The overturning piece 12 is provided with a bearing groove 1211. The bearing groove 1211 is used for bearing a battery piece 4. The bearing groove 1211 is provided with an adsorption part 12123 on the groove surface. The overturning piece 12 can rotate around the rotating shaft 13, so that the bearing groove 1211 is overturned from a first position to a second position, thereby overturning the battery piece 4 in the bearing groove 1211 from the first position to the second position. The first conveying mechanism 2 is used for conveying the battery piece 4 into the bearing groove 1211 in the first position. The second conveying mechanism 3 is used for outputting the battery piece 4 in the bearing groove 1211 in the second position to a third position. The adsorption part 12123 is used for adsorbing the battery piece 4 in the first position, so that the battery piece 4 in the bearing groove 1211 is fixed in the bearing groove 1211, thereby avoiding the movement of the battery piece 4 during the overturning from the first position to the second position. The adsorption part 12123 is also used for releasing the battery piece 4 in the second position, thereby facilitating the output of the battery piece 4 out of the bearing groove 1211 by the second conveying mechanism 3.

[0037] In the embodiments of the present application, the first conveying mechanism 2 can convey the battery piece 4 into the bearing groove 1211 in the first position. Then the adsorption part 12123 in the bearing groove 1211 in the first position adsorbs the battery piece 4, so that the battery piece 4 is fixed in the bearing groove 1211. After the overturning piece 12 overturns the battery piece 4 to the second position, the adsorption part 12123 releases the battery piece 4. The second conveying mechanism 3 outputs the battery piece 4 in the bearing groove 1211 in the second position to the next station, thereby effectively overturning the battery piece 4. The hidden cracks or fragments caused by the shaking of the battery piece 4 during the overturning process are avoided. Moreover, the fixing of the battery piece 4 in the bearing groove 1211 avoids the positional deviation of the battery piece 4 during the overturning process. The battery piece 4 in the bearing groove 1211 in the second position can be accurately placed on the second conveying mechanism 3, thereby improving the accuracy of the piece placement, avoiding the scratching of the battery piece 4 caused by the edge, reducing the fragment rate and improving the product yield of the battery piece 4. Moreover, the conveying of the battery piece 4 into the bearing groove 1211 in the first position by the first conveying mechanism 2 and the output of the battery piece 4 in the bearing groove 1211 in the second position by the second conveying mechanism 3 not only effectively improve the production efficiency, but also further avoid the damage of the battery piece 4, thereby further improving the product yield of the battery piece 4.

[0038] In some preferred embodiments, please refer to Figure 4The turnover member 12 comprises at least one bearing unit 121, each bearing unit 121 comprises a plurality of bearing slots 1211, the plurality of bearing slots 1211 are evenly spaced on the same circle, the center of the circle is located on the axis of the rotating shaft 13, and each bearing slot 1211 can be used to bear a piece of battery piece 4. In this embodiment, each bearing unit 121 comprises a plurality of bearing slots 1211, thereby further improving the production efficiency.

[0039] In some more preferred embodiments, the turnover member 12 comprises a plurality of bearing units 121, the plurality of bearing units 121 are sequentially arranged along the rotating shaft 13 in the axial direction, the production efficiency can be further improved, and the bearing units 121 do not interfere with each other.

[0040] As an example, please refer to Figure 4 The plurality of bearing units 121 are the same structure, so that the turnover member 12 can simultaneously turn over a plurality of battery pieces 4 from the first position to the second position, thereby further improving the production efficiency.

[0041] As an optional embodiment, please refer to Figure 4 The turnover member 12 can comprise two bearing units 121. The two bearing units 121 are sequentially arranged along the rotating shaft 13 in the axial direction, and the two bearing units 121 are completely the same structure, each bearing unit 121 comprises a plurality of bearing slots 1211, the bearing slots 1211 in the two bearing units 121 are correspondingly arranged, that is, the turnover member 12 can simultaneously turn over two battery pieces 4 together to the second position.

[0042] As an optional embodiment, each bearing unit 121 comprises six bearing slots 1211, and the interval between the adjacent two bearing slots 1211 is 60°.

[0043] In this embodiment, the turnover member 12 can pause once every 60° of rotation, so that the first conveying mechanism 2 can send the battery piece 4 into the bearing slot 1211 located at the first position, and the second conveying mechanism 3 can also output the battery piece 4 in the bearing slot 1211 at the second position from the turnover member 12.

[0044] It can be understood that the battery piece 4 can be sent into the bearing slot 1211 located at the first position and the battery piece 4 in the bearing slot 1211 at the second position can be output from the turnover member 12 at the same time, or not at the same time, which can be set according to the actual situation, and will not be repeated here.

[0045] It should be noted that the turnover member 12 can also comprise one or three or more bearing units 121, and each bearing unit 121 can also comprise other number of bearing slots 1211, which can be set according to the actual situation, and will not be repeated here.

[0046] By way of example, reference will be made to Figure 2 , Figure 4 and Figure 5 The battery piece 4 has two first side edges 41 and two second side edges 42, the two first side edges 41 are oppositely arranged, and the two second side edges 42 are oppositely arranged. The turnover member 12 further comprises a body 122 fixed to the rotating shaft 13. Each of the carrying units 121 comprises a plurality of carrying bodies 1212, and each of the carrying bodies 1212 has a carrying groove 1211. Specifically, each of the carrying bodies 1212 comprises two first insertion parts 12121 and a second insertion part 12122, and the two first insertion parts 12121 and the second insertion part 12122 are respectively fixed to the body 122. One of the first insertion parts 12121 is arranged corresponding to one of the first side edges 41, the other first insertion part 12121 is arranged corresponding to the other first side edge 41, and the second insertion part 12122 corresponds to one of the second side edges 42. The two first insertion parts 12121 and the second insertion part 12122 jointly define the carrying groove 1211 suitable for the insertion of the battery piece 4.

[0047] The two first insertion parts 12121 can be symmetrically arranged, thereby more stably supporting the battery piece 4, and the two first insertion parts 12121 are symmetrically provided with the suction parts 12123, thereby more stably adsorbing the battery piece 4 and further avoiding the movement of the battery piece 4.

[0048] In one example, reference will be made to Figure 2 and Figure 5 The first insertion part 12121 comprises two first insertion blocks 121211, and the two first insertion blocks 121211 are fixed to the body 122 at intervals. The interval between the two first insertion blocks 121211 is configured as a first insertion groove 121212, the first insertion groove 121212 is inserted and matched with the first side edge 41, and one of the first insertion blocks 121211 is provided with the suction part 12123. Not only is the structure simple, but also the battery piece 4 can be effectively adsorbed. The second insertion part 12122 comprises two second insertion blocks 121221, and the two second insertion blocks 121221 are fixed to the body 122 at intervals. The interval between the two second insertion blocks 121221 is configured as a second insertion groove 121222, and the second insertion groove 121222 is inserted and matched with the second side edge 42. The two first insertion grooves 121212 and the second insertion groove 121222 jointly form the carrying groove 1211. One of the first side edges 41 of the battery piece 4 is inserted into one of the first insertion grooves 121212, the other first side edge 41 of the battery piece 4 is inserted into the other first insertion groove 121212, and one of the second side edges 42 of the battery piece 4 is inserted into the second insertion groove 121222.

[0049] In the present example, the bearing groove 1211 is composed of two first insertion grooves 121212 and one second insertion groove 121222, which not only can effectively bear the battery piece 4, but also can reduce the contact area between the turnover piece 12 and the battery piece 4 as much as possible, avoid scratching the battery piece 4 when inserting the bearing groove 1211, and more conveniently transport the battery piece 4 into the bearing groove 1211 by the first conveying mechanism 2, and the same, more conveniently output the battery piece 4 in the bearing groove 1211 to the outside of the bearing groove 1211 by the second conveying mechanism 3.

[0050] As an optional embodiment, the adsorption part 12123 is a suction cup. As an example, the adsorption part 12123 can be provided with adsorption holes (not shown in the figure), which can be micropores, thereby effectively avoiding adsorption from damaging the structure of the battery piece 4. For example, the diameter of the adsorption hole can be less than 2 nanometers.

[0051] In some preferred embodiments, please refer to Figures 1 to 5 The battery piece turnover device further comprises a driving mechanism 5, which can provide power for the turnover piece 12.

[0052] As an optional embodiment, the rotating shaft 13 can be connected to the output end of the driving mechanism 5, and the driving mechanism 5 drives the turnover piece 12 to rotate with the rotating shaft 13.

[0053] In some examples, the driving mechanism 5 can be a motor.

[0054] In some preferred embodiments, please refer to Figure 2 and Figure 4 The battery piece turnover device further comprises a solenoid valve (not shown in the figure), a first sensing piece 6 and a second sensing piece 7, and the first sensing piece 6 and the second sensing piece 7 are respectively connected with the solenoid valve. Among them, the solenoid valve is arranged one by one with the bearing groove 1211, and the solenoid valve is used to control the adsorption part 12123 in the corresponding bearing groove 1211 to adsorb the battery piece 4, and the solenoid valve is also used to control the adsorption part 12123 in the corresponding bearing groove 1211 to release the battery piece 4. That is, the adsorption part 12123 of each bearing groove 1211 works independently and does not affect each other. The first sensing piece 6 is arranged at the first position, and the first sensing piece 6 is used to sense whether the bearing groove 1211 at the first position carries the battery piece 4. The second sensing piece 7 is arranged at the second position, and the second sensing piece 7 is used to sense whether the bearing groove 1211 at the second position carries the battery piece 4.

[0055] As an example, when the turnover member 12 rotates to one of the carrying grooves 1211 in the first position, the turnover member 12 stops rotating, and the first conveying mechanism 2 conveys the battery piece 4 into the carrying groove 1211 in the first position. At this time, the first sensing member 6 senses that the battery piece 4 is carried in the carrying groove 1211 in the first position, and triggers a vacuum extraction signal. The electromagnetic valve corresponding to the carrying groove 1211 in the first position receives the vacuum extraction signal, and causes the adsorption part 12123 of the carrying groove 1211 in the first position to be in a negative pressure state, thereby adsorbing and fixing the battery piece 4 in the carrying groove 1211 in the first position, and then the turnover member 12 continues to rotate. When one of the carrying grooves 1211 rotates to the second position, the turnover member 12 stops rotating. At this time, if the second sensing member 7 senses that the battery piece 4 is carried in the carrying groove 1211 in the second position, a vacuum breaking signal is triggered. The electromagnetic valve corresponding to the carrying groove 1211 in the second position receives the vacuum breaking signal, and causes the adsorption part 12123 of the carrying groove 1211 in the second position to release the battery piece 4 in the carrying groove 1211 in the second position, and the second conveying mechanism 3 conveys the battery piece 4 to the next station.

[0056] In the embodiment, the adsorption part 12123 of each carrying groove 1211 is controlled separately, and the adsorption part 12123 always adsorbs the battery piece 4 during the rotation of the battery piece 4 from the first position to the second position, thereby more effectively avoiding the movement of the battery piece 4.

[0057] It can be understood that in other embodiments, one electromagnetic valve can control the adsorption parts 12123 of all the carrying grooves 1211 at the same time, or one electromagnetic valve can control the adsorption parts 12123 of multiple carrying grooves 1211 at the same time. The electromagnetic valve is a prior art, which can be set according to the actual situation, and will not be described here.

[0058] In some preferred embodiments, the battery piece turnover device further comprises a rotary joint (not shown in the figure), which can be fixed to the base 11 and connected to the air pipe (not shown in the figure) of the vacuum extraction mechanism. The turnover member 12 is fixed to the rotating shaft 13, and the turnover member 12 and the rotating shaft 13 are provided with a vacuum extraction channel (not shown in the figure) that communicates with the adsorption part 12123 and the rotary joint. This embodiment can avoid the problem of air pipe entanglement during the operation of the battery piece turnover device caused by the direct connection of the air pipe and the adsorption part 12123.

[0059] As an example, the rotary joint can be a 360° rotary joint, which can be installed at one end of the rotating shaft 13.

[0060] In some preferred embodiments, the number of the first conveying mechanisms 2 and the second conveying mechanisms 3 is the same as the number of the carrying units 121, and the first conveying mechanisms 2 and the second conveying mechanisms 3 can be arranged one-to-one with the carrying units 121, please refer to Figure 4 Each first conveying mechanism 2 can send the battery piece 4 into the carrying groove 1211 in the first position in the corresponding carrying unit 121, and each second conveying mechanism 3 can output the battery piece 4 in the carrying groove 1211 in the second position in the corresponding carrying unit 121 to the third position, thereby further improving the production efficiency.

[0062] It can be understood that in some embodiments, the first limiting piece 22 can have one group. In other embodiments, the first limiting piece 22 can have multiple groups, and the multiple groups of the first limiting piece 22 are uniformly and interval arranged along the conveying direction of the first conveying belt 21, and each group of the first limiting piece 22 cooperates with one battery piece 4.
