[0029] Example:

[0030] In a first aspect, embodiments of this application provide a battery cell flipping device, see [link to relevant documentation]. Figures 1 to 3 As shown, it includes a flipping mechanism 1 and a carrier plate mechanism 2; the flipping mechanism 1 includes a first plate 11, a first support plate 12 and a movable support assembly 13 disposed opposite to both ends of the first plate 11, and a flipping assembly 14 disposed between the first support plate 12 and the movable support assembly 13; the flipping assembly 14 includes a rotating suction member 141 with both ends connected to the first support plate 12 and the movable support assembly 13 respectively; the carrier plate mechanism 2 includes a carrier plate 21 that cooperates with the rotating suction member 141. After the rotating suction member 141 flips the battery cell received from the carrier plate 21, the carrier plate 21 then unloads the battery cell from the rotating suction member 141.

[0031] The battery piece turning device comprises the turning mechanism 1. In use, the turning mechanism 1 sucks the battery piece from the carrier plate 21 through the rotary suction member 141 and turns the battery piece sucked thereon through the rotation of the rotary suction member 141. After turning, the carrier plate 21 discharges the battery piece from the rotary suction member 141 through cooperation with the rotary suction member 141 in the turning assembly 14. The battery piece turning device turns the received battery piece directly through the turning mechanism 1, then discharges the battery piece through the carrier plate 21 of the carrier plate mechanism 2, has high turning efficiency, does not need secondary suction, reduces damage to the battery piece, guarantees the yield of the battery piece, has simple overall structure, simplifies the component setting of the turning device and reduces the maintenance area.

[0032] The turning assembly 14 further comprises a rotary driving member 142 arranged on the first support plate 12. The rotary suction member 141 comprises a vacuum air pipe 1411 connected to the output end of the rotary driving member 142 and a suction nozzle 1412 vertically arranged on the vacuum air pipe 1411. Both ends of the vacuum air pipe 1411 are rotationally connected to the first support plate 12 and the movable support assembly 13, respectively. Optionally, the number of the suction nozzles 1412 arranged on the corresponding area of each battery piece is at least two, so as to guarantee the stability of the suction nozzles 1412 to the battery piece. For example, when the battery piece is rectangular, the number of the suction nozzles 1412 can be two, and the suction nozzles 1412 are arranged along the diagonal line of the battery piece. It can be understood that the vacuum air pipe 1411 is connected to a negative pressure generating device such as a vacuum generator through an air pipe. Both ends of the vacuum air pipe 1411 are rotationally connected to the first support plate 12 and the movable support assembly 13 through rotary bearings, respectively.

[0033] As an option, the number of the rotary driving members 142 can be optional. For example, in some embodiments, the number of the rotary driving members 142 is 1, and the turnover mechanism 1 further comprises a third plate body 2112 arranged on the side of the first support plate 12 away from the rotary driving member 142, the vacuum air pipe 1411 is connected to the third plate body 2112, and the rotating end of the rotary driving member 142 is connected to the third plate body 2112. In use, the rotary driving member 142 drives the third plate body 2112 to rotate, thereby driving the vacuum air pipe 1411 to rotate as a whole; in this structure, the rotary driving member 142 can be arranged to realize the turnover of the battery piece adsorbed on the suction nozzle 1412, thereby saving the number of the rotary driving member 142 and reducing the production cost. In other embodiments, the rotary driving member 142 is arranged one-to-one corresponding to the vacuum air pipe 1411, and the rotary driving member 142 drives the vacuum air pipe 1411 to rotate synchronously to realize the turnover operation. In this structure, the arrangement space of the rotary suction member 141 is saved, the space occupied by the equipment is saved, and the flexibility of the operation of the rotary suction member 141 is improved.

[0034] The movable support assembly 13 comprises a movable connecting member 131 arranged on the first plate body 11, a first limiting member 132 connected to the movable connecting member 131, and a second support plate 133 arranged on the end of the vacuum air pipe 1411 away from the first support plate 12; the second support plate 133 is provided with a limiting cooperation structure 134 cooperating with the first limiting member 132.

[0035] Correspondingly, the two ends of the vacuum air pipe 1411 are movably connected to the first support plate 12 and the second support plate 133 through rotating bearings respectively. The end of the first limiting member 132 away from the movable connecting member 131 is provided with a first limiting protrusion, and the structure of the first limiting member 132 can be selected according to actual needs, for example: in some embodiments, the first limiting member 132 is in the shape of a whole, comprising a main body part and ear parts vertically arranged on both ends of the main body part, one of the ear parts is arranged on the first plate body 11 through the rotating connecting member, and the other ear part is connected to the first limiting groove in cooperation.

[0036] The vacuum air pipes 1411 are arranged in parallel with each other to form a first gap 1413, and the second support plate 133 is arranged one-to-one corresponding to the vacuum air pipe 1411; see Figure 4 and Figure 5As shown, the carrier plate 21 comprises a frame body 211 and cantilevers 212 arranged in the area surrounded by the frame body 211; the frame body 211 is in the shape of a Chinese character “fang” as a whole, comprising a second plate body 2111 and a third plate body 2112 vertically arranged on one side of the second plate body 2111, and the cantilevers 212 are arranged on the same side of the second plate body 2111 and parallel to the third plate body 2112; the second gaps 213 are formed between the cantilevers 212, which are arranged to allow the cantilevers 212 to pass through the rotary material suction member 141; the cross-sectional area of the cantilevers 212 gradually decreases from the end connected to the second plate body 2111 to the end away from the second plate body 2111.

[0037] Referring to Figure 6 As shown, the frame body 211 and the cantilevers 212 are connected in cooperation, so that the overall shape of the carrier plate 21 is similar to a shovel, one end of which is in a closed structure formed by the second plate body 2111, and the other end is in an open structure 31 formed between the cantilevers 212, so that the carrier plate 21 can be arranged inside the vertical projection of the first gap 1413 when the battery pieces are discharged, and finally the battery pieces are carried in the positioning area. The structure of the cantilevers 212 is arranged such that the mass of the cantilevers 212 gradually decreases from the end connected to the second plate body 2111 to the end away from the second plate body 2111, so that the weight of the carrier plate 21 gradually decreases from the end close to the second plate body 2111 to the end away from the second plate body 2111, which improves the structural stability of the carrier plate 21 during movement, avoids excessive shaking of the cantilevered end, and improves the stability of the transmission of the battery pieces.

[0038] Specifically, the cantilevers 212 are in the shape of a wedge or a right-angled trapezoidal body as a whole, and the end with a larger cross-sectional area of the cantilevers 212 is connected to the second plate body 2111. In actual operation, the number of the cantilevers 212, the number of the vacuum air pipes 1411, the number of the positioning areas on the carrier plate 21, and the number of the suction nozzles 1412 can be specifically set according to actual needs. For example, the number of the vacuum air pipes 1411 is n, the number of the cantilevers 212 is n-1, the number of the positioning areas on the carrier plate 21 is x, and the number of the suction nozzles 1412 can be 2x, where n and x are positive integers.

[0039] The two sides of the cantilever 212 and the side wall opposite to the cantilever 212 of the third plate body 2112 are provided with positioning members 214, and the positioning members 214 jointly form a positioning area; the positioning member 214 comprises a second limiting protrusion 2141 and a clamping point 2142 provided on the second limiting protrusion 2141; the second limiting protrusion 2141 is in the shape of a slope prism, and at least a plane connected with the clamping point 2142 of the second limiting protrusion 2141 is an inclined plane, and the inclination angle of the inclined plane gradually increases from the connection area of the clamping point 2142 to the direction away from the clamping point 2142.

[0040] When the positioning member 214 positions the battery piece, the battery piece is arranged on the clamping point 2142, and the second limiting protrusion 2141 limits the battery piece to prevent the battery piece from shaking, thereby improving the stability of the positioning of the battery piece. In addition, the second limiting member is in the shape of a slope prism, which ensures that the second limiting member plays a limiting role on the battery piece while buffering the shaking of the battery piece, thereby avoiding the damage of the battery piece caused by the excessive force between the battery piece and the second limiting member when the battery piece shakes.

[0041] Specifically, as an option, the shape of the second limiting protrusion 2141 can be a triangular prism, a trapezoidal column or other column structures with inclined planes, as long as the inclined surface structure of the second limiting protrusion 2141 is connected to the clamping point 2142, and the inclination angle of the inclined surface structure gradually increases from the clamping point 2142 upward.

[0042] Referring to Figures 1 to 3 As shown, the movable support assembly 13 further comprises a third limiting protrusion 135 arranged on the side of the second support plate 133 away from the rotating material suction member 141; the battery piece turnover device further comprises a positioning plate 3, and the positioning plate 3 is provided with an opening structure 31 through which the carrier plate 21 passes and a second limiting groove 32 matched with the third limiting protrusion 135.

[0043] When in use, the third limiting protrusion 135 and the second limiting groove 32 are matched to further limit the turnover assembly 14, thereby improving the stability of the turnover assembly 14. In addition, when the first limiting member 132 is opened, that is, the first limiting protrusion is separated from the limiting matching structure 134, and the vacuum air pipe 1411 is unloaded, the third limiting protrusion 135 is inserted into the second limiting groove 32 to limit the rotary material suction piece 141, thereby ensuring the stability of the rotary material suction piece 141, so that the battery piece is stably adsorbed on the suction nozzle 1412, and the end of the rotary material suction piece 141 is prevented from shaking to damage the battery piece. During the transferring process of the battery piece by the turnover assembly 14, the carrier plate 21 carrying the turned-over battery piece passes through the opening structure 31 to transfer the battery piece to the next process.

[0044] When the rotary material suction piece 141 rotates to the suction nozzle 1412 facing the first plate body 11, a third gap 15 is arranged between the first plate body 11 and the rotary material suction piece 141. The third gap 15 provides space for the turnover of the rotary material suction piece 141 and facilitates the movement of the carrier plate 21.

[0045] The turnover mechanism 1 further comprises a first lifting driving assembly 16 and a first horizontal driving assembly 17. The first plate body 11 is arranged at the telescopic end of the first lifting driving assembly 16, and the first lifting driving assembly 16 is connected to the output end of the first horizontal driving assembly 17. When in use, the first plate body 11 is driven to move up and down by the first lifting driving assembly 16, and the first horizontal driving assembly 17 drives the first plate body 11 to move along the horizontal direction by driving the first lifting driving assembly 16 to move along the horizontal direction. It should be noted that the vertical direction in the present application refers to the direction parallel to the z-axis in the space coordinate system, and the horizontal direction refers to the plane parallel to the plane formed by the x-axis and y-axis in the space coordinate system, and the x-axis, y-axis and z-axis are perpendicular to each other.

[0046] The carrier plate mechanism 2 further comprises a second vertical driving assembly 22 and a second horizontal driving assembly 23. The second horizontal driving assembly 23 is connected to the output end of the second vertical driving assembly 22, and the output end of the second horizontal driving assembly 23 is connected to the second plate body 2111. The carrier plate 21 moves along the vertical direction or the horizontal direction under the cooperation of the second vertical driving assembly 22 and the second horizontal driving assembly 23, thereby supplying the battery piece to the turnover mechanism 1 and removing the battery piece from the turnover mechanism 1.

[0047] The operation steps of the battery piece turning device for turning the battery piece include: moving the carrier plate 21 to the area corresponding to the rotary material suction piece 141 through cooperation of the second horizontal driving assembly 23 and the second vertical driving assembly 22, at this time, the suction nozzle 1412 on the rotary material suction piece 141 is arranged in a direction away from the first plate body 11, and the first limiting piece 132 in the movable support assembly 13 cooperates with the limiting cooperation structure 134 to limit the rotary material suction piece 141; the rotary material suction piece 141 sucks the battery piece from the carrier plate 21 through the suction nozzle 1412; the rotary driving piece 142 drives the rotary material suction piece 141 to rotate, when the suction nozzle 1412 drives the battery piece to rotate to the direction of the first plate body 11, the turning operation of the battery piece is realized; in use, after the battery piece is turned by the turning mechanism 1, the suction nozzle 1412 is depressurized, the first limiting piece 132 is separated from the limiting cooperation structure 134, and the carrier plate 21 is moved to the position corresponding to the rotary material suction piece 141 under the cooperation and driving of the second horizontal driving assembly 23 and the second vertical driving assembly 22; the cantilever 212 moves to the projection area of the first gap 1413, the second vertical driving assembly 22 drives the carrier plate 21 to move upward, so that the battery piece is positioned in the positioning area, and the second horizontal driving assembly 23 drives the carrier plate 21 to move out of the opening structure along the horizontal direction.
