[0032] The following is a further detailed description of the present invention in conjunction with the attached Figures 1 to 8 This is not a limitation to the present invention.

[0033] As shown in the figure, in an embodiment of the present invention, the battery cell conveying device includes a first conveying mechanism 100, a guiding mechanism 200, an orientation adjustment mechanism 300, and a second conveying mechanism 400. The output end of the first conveying mechanism 100 is disposed at the inlet end of the guiding mechanism 200. The output end of the guiding mechanism 200 is disposed at the inlet end of the orientation adjustment mechanism 300. The outlet end of the orientation adjustment mechanism 300 is disposed at the inlet end of the second conveying mechanism 400. And the guiding mechanism 200 is inclined and disposed between the first conveying mechanism 100 and the orientation adjustment mechanism 300.

[0034] The technical solution of the present invention non - manually adjusts the battery cell body conveyed in the first orientation state to the second orientation state through the orientation adjustment mechanism, and transfers and conveys it to the second conveying mechanism, thereby reducing the processes of manually adjusting its orientation and manual transfer; thus improving the operation fluency and work efficiency. In addition, by the inclined guiding mechanism, the use of power driving sources is reduced, and it is ensured that the battery cell body can be quickly transferred to the orientation adjustment mechanism, thereby reducing the process of manual transfer; thus improving the operation fluency and work efficiency.

[0035] Specifically, in some embodiments, such as Figure 1 and 2As shown, the first conveying mechanism 100 includes a chain rotation driving component 120 and at least one placement seat 110 connected to the chain rotation driving component 120; a horizontal placement groove 111 is provided on the placement seat 110; the horizontal placement groove 111 is used to support (generally in the form of snap-fit assembly to prevent the core body from falling off) the core body 5 in a horizontal state. That is to say, this structure conveys multiple groups of core bodies 5 in the vertical space through the chain rotation driving component 120, thereby improving the orderliness of processing, and improving the fluency and working efficiency of operations. Among them, in some embodiments, such as Figure 1 and 2 As shown, the included angle between the conveying plane formed by the chain rotation driving component 120 and the horizontal plane where it is located is α; α satisfies: 65° ≤ α ≤ 85°. Among them, α can be 65°, 68°, 70°, 75°, 85°, etc.; preferably 75°. This structure can ensure the orderliness of the blanking of the core body 5 through the chain rotation driving component 120 with a larger inclination angle, and avoid the core body 5 falling off during the conveying process due to a small inclination angle; in addition, through the inclined chain rotation driving component 120 combined with the inclined guiding mechanism 200, the input of the power source can be reduced and the power of the power source can be lowered; furthermore, the use of the power driving source can be reduced, and it can be ensured that the core body can be quickly transferred to the placement direction adjustment mechanism.

[0036] Specifically, in some embodiments, such as Figure 2 and 3 As shown, the placement seat 110 includes a first limiting protrusion 112, a horizontal support portion 113, a second limiting protrusion 114 and a connecting block 115; one end of the connecting block 115 is connected to one side surface of the horizontal support portion 113; the other end of the connecting block 115 is connected to the chain rotation driving component 120; the first limiting protrusion 112 and the second limiting protrusion 114 are respectively connected side by side to the other side surface of the horizontal support portion 113 away from the connecting block 115; and the horizontal placement groove 111 corresponding to the outer shape of the core body 5 is formed between the first limiting protrusion 112, the second limiting protrusion 114 and the horizontal support portion 113. That is to say, this structure can ensure the assembly stability of the core body 5 through the formed U-shaped horizontal placement groove 111, and avoid phenomena such as falling off during the vertical conveying process. Among them, in some embodiments, such as Figure 2As shown in the figure, the second limiting protrusion 114 and the first limiting protrusion 112 are arranged side by side in sequence along the rotation and conveying direction of the chain rotation driving member 120; and the relational expression between the height H1 of the first limiting protrusion 112 and the height H2 of the second limiting protrusion 114 satisfies: H1 > H2. That is to say, the first limiting protrusion 112 is arranged in front of the second limiting protrusion 114, and the protrusion height of the first limiting protrusion 112 is greater than the protrusion height of the second limiting protrusion 114, so as to further improve the limiting effect on the battery cell body 5 and avoid phenomena such as the battery cell body falling off during the vertical conveying process.

[0037] Specifically, in some embodiments, such as Figure 1 and 2 As shown in the figure, the chain rotation driving member 120 includes a first bracket 121, a transmission wheel set 122, a rotation conveying chain 123 and a first driving motor 124; the first driving motor 124 is connected to the first bracket 121; each transmission wheel in the transmission wheel set 122 is movably connected to the first bracket 121; the first driving motor 124 is drivingly connected to one of the transmission wheels; the rotation conveying chain 123 is wound around the outer surfaces of each transmission wheel in the transmission wheel set 122; all the placement seats 110 (the connecting blocks 115 therein) are connected to the outer side surface of the rotation conveying chain 123; and the horizontal placement groove 111 is arranged on the side surface of the placement seat 110 away from the rotation conveying chain 123.

[0038] Specifically, in some embodiments, such as Figure 1 and 4 As shown in the figure, the guiding mechanism 200 includes a guiding track 220 and at least two demolding support plates 230; a through cavity is provided between two adjacent demolding support plates 230; the through cavity is used for the placement seat 110 to pass through; and a demolding contact surface is arranged on the side surface of each demolding support plate 230 facing the output end of the first conveying mechanism 100; one end of the guiding track 220 is communicated with the side end of the demolding support plate 230 away from the first conveying mechanism 100; the other end of the guiding track 220 is communicated with the inlet end of the placement direction adjusting mechanism 300. That is to say, multiple groups of demolding support plates 230 enable the battery cell body 5 placed in the horizontal placement groove 111 to be lifted and separated from the placement seat 110, and enable the placement seat 110 to be circulated and discharged from the middle through cavity, so as to ensure that the battery cell body can be quickly transferred to the placement direction adjusting mechanism. Among them, as Figure 4 As shown in the figure, the demolding contact surface includes a demolding arc surface and a demolding flat surface arranged in sequence from the first conveying mechanism 100 towards the guiding track 220 direction. That is, the demolding arc surface protrudes in an arc shape from the body of the demolding support plate 230 towards the outside. This structure can effectively reduce the impact damage between the demolding support plate 230 and the battery cell body 5, and further improve the safety and stability of conveying. Further, in some embodiments, such as Figure 4As shown, the included angle between the guiding track 220 and the horizontal plane where it is located is β; the β satisfies: 15° ≤ β ≤ 40°. Among them, α can be 15°, 18°, 20°, 25°, 40°, etc.; preferably 20°. Through the action of a smaller inclined acute angle, this structure ensures that the battery cell body 5 can be transported without a power source, and avoids excessive impact force during the transportation of the battery cell body 5, thereby improving the safety and efficiency of transportation.

[0039] Specifically, in some embodiments, such as Figure 1 and 4 As shown, the guiding mechanism 200 further includes an adapter block 210; the adapter block 210 is arranged between the guiding track 220 and the demolding support plate 230; and there is a buffer gap 250 between the adapter block 210 and the guiding track 220; the relationship between the width M of the buffer gap 250 and the width N of the battery cell body 5 satisfies: M = N*(1 / 3 - 1 / 2). Among them, the upper surface of the adapter block 210, the upper surface of the demolding support plate 230 and the conveying upper surface of the guiding track 220 are arranged in a flush manner. This structure can reduce the initial speed of the battery cell body 5 entering the guiding track 220 through the adapter block 210 and the buffer gap 250, thereby effectively reducing the impact stress when the battery cell body 5 finally enters the placement direction adjustment mechanism 300; and then improving the safety and stability of transportation. Among them, in some embodiments, such as Figure 4 As shown, the guiding mechanism 200 further includes a first side limiting plate 240; the first side limiting plate 240 is connected to the left and / or right end faces in the conveying direction of the guiding track 220 to prevent the battery cell body 5 from falling off and other phenomena under the action of no driving source.

[0040] Specifically, in some embodiments, such as Figure 1 and 5 As shown, the placement direction adjustment mechanism 300 includes a steering guiding component 310 and a pushing adjustment component 320; the input end of the pushing adjustment component 320 is communicated with the outlet end of the guiding track 220; a steering channel 313 is provided in the steering guiding component 310; the inlet end of the steering channel 313 is communicated with the output end of the pushing adjustment component 320; the outlet end of the steering channel 313 is communicated with the input end of the second conveying mechanism 400. This structure intercepts the battery cell body 5 conveyed by the guiding track 220 through the pushing adjustment component 320, and then pushes it to the steering guiding component 310; and then through the steering channel 313 inside the steering guiding component 310 to adjust the steering of the battery cell body 5, thereby ensuring the smoothness of the steering operation, reducing the processes of manually adjusting its placement direction and manual transfer; and then improving the smoothness of the operation and work efficiency.

[0041] Specifically, in some embodiments, such as Figure 5 and 7As shown, the pushing and adjusting component 320 includes a first transverse driving component 321, a mounting block 322, a pushing block 323, and a baffle 324; the baffle 324 is arranged above the second conveying mechanism 400 and at the outlet end of the guiding track 220; and a pushing cavity 325 is provided between the baffle 324 and the second conveying mechanism 400; the pushing cavity 325 is communicated with the outlet end of the guiding track 220; and the pushing cavity 325 is communicated with the steering channel 313; the first transverse driving component 321 is connected to the surface of the baffle 324 away from the guiding track 220 and is connected to one end of the mounting block 322; the other end of the mounting block 322 is connected to one end of the pushing block 323; the other end of the pushing block 323 is arranged inside the pushing cavity 325. Among them, the first transverse driving component 321 can be a first transverse driving cylinder or a first transverse driving lead screw. This structure blocks and operates through the baffle 324 on the front to make the electric core body 5 be transported and limited to be stationary; thus, it is beneficial to promote the orderly operation of the pushing, adjusting, and steering operations.

[0042] Specifically, in some embodiments, as Figure 7 and 8 shown, the steering guiding component 310 includes a guiding arc block 311 and a guiding limiting block 312 arranged side by side; a steering channel 313 is formed between the guiding arc block 311 and the guiding limiting block 312; and a guiding arc surface 314 is provided on the surface of the guiding arc block 311 facing the guiding limiting block 312; an adjusting arc surface 315 is provided on the surface of the guiding limiting block 312 facing the guiding arc block 311. Under the guiding and conveying of the guiding arc surface 314 and the guiding and pulling for steering of the adjusting arc surface 315, this structure makes the electric core body 5 in the horizontally placed state change to the vertically transported state; thus, the steering adjustment operation without a power source is realized, and the operation efficiency is further improved; the input of manpower and material resources is reduced. Among them, in some embodiments, the guiding arc surface 314 is arc-shaped and protrudes from the body of the guiding arc block 311 towards the steering channel 313; the adjusting arc surface 315 is arc-shaped and recessed from the steering channel 313 towards the body of the guiding limiting block 312. Further, the projection of the guiding arc surface 314 on the guiding limiting block 312 and the adjusting arc surface 315 have at least partial overlap; to reduce the impact and damage phenomenon between the electric core body 5 and the guiding limiting block 312, and improve the speed and efficiency of the steering operation.

The second transverse movement driving member 420 is connected to the side end face of the second bracket 410 and is drivingly connected to one end of the pusher member 430. The other end of the pusher member 430 is arranged inside the conveying channel 401. Among them, in some embodiments, as Figure 6 shown, the pusher member 430 includes a pusher block 431 and a splicing block 432 which are connected to each other. The pusher block 431 is arranged inside the conveying channel 401. The splicing block 432 is connected to the second transverse movement driving member 420. Further, an L-shaped or T-shaped structure is formed between the pusher block 431 and the splicing block 432. The second transverse movement driving member 420 is selected from a second transverse movement driving cylinder or a second transverse movement driving lead screw. Still further, in some embodiments, as Figure 6 shown, at least one second side limiting plate 440 is provided on the side end face of the second bracket 410.

And the second side limiting plate 440 and the second bracket 410 form the conveying channel 401 therebetween.
