Regarding the membrane separation assembly 5, a separation member for fixing the tearing portion 03 is included, as shown in fig. 5, 6 and 7, the separation member includes a predetermined positioning member and a fine positioning member, wherein the specific position of the tearing portion 03 is shown with reference to fig. 7; the pre-positioning member and the fine positioning member are mounted on the positioning plate 51; in the present embodiment, the pre-positioning member employs at least two pre-positioning suction cups 52 for sucking the tear-off portion 03; the fine positioning component comprises a film separating clamping jaw 53 and a film separating cylinder 54 which is hinged; the film separating cylinder 54 drives the film separating clamping jaw 53 to perform station switching in the horizontal direction and the vertical direction, and when the film separating clamping jaw 53 is in the vertical station, the film separating clamping jaw is attached to the clamping plate 55 fixed on the positioning plate 51. The membrane separation assembly 5 further includes a transfer member 56 and a carrier member 57; the transfer member 56 drives the separation members to move in the vertical direction and the horizontal direction, respectively; the transfer member 56 is connected with the positioning plate 51 and comprises a lifting cylinder 561 and a translation cylinder 562; the supporting member 57 is arranged at the side of the separating member and supports the separated cell film 02; the carrier member 57 includes a carrier plate 571 and a lift cylinder 572 for driving the carrier plate 571 up and down.
In the working scene, the rotary clamping assembly 4 moves back and forth between the positioning assembly 2 and the membrane separating assembly 5, and performs a first linear motion towards the separating member, a second linear motion away from the separating member and a rotary motion after clamping the battery cell 01; the first linear motion and the second linear motion act on the front and back of the separation member fixed tearing part 03, and the second linear motion and the rotary motion are synchronously executed; when the rotary clamping assembly 4 executes the first linear motion, the positioned battery cell is rotated from a horizontal state to a vertical state by 90 degrees, and the tearing part 03 is opposite to the preset positioning member.
As shown in fig. 7, in the initial state, the battery cell 01 is vertical, the film separation clamping jaw 53 is horizontal, the tearing portion 03 of the battery cell 01 faces the predetermined positioning suction cup 52, and the tearing portion 03 is sucked by the predetermined positioning suction cup 52. As shown in fig. 8, the rotary gripping assembly 4 performs a second rectilinear motion, realizes retraction, and performs a rotary motion during retraction, in which the positioning suction cup 52 is always attracted to the tear-off portion 03. When the cell film 02 is torn to a certain length, as shown in fig. 9, the film separating cylinder 54 drives the film separating clamping jaw 53 to switch from a horizontal state to a vertical state, so that the tearing part 03 is clamped between the film separating clamping jaw 53 and the clamping plate 55. Afterwards, the rotary clamping assembly 4 drives the battery cell 01 to continuously retract and rotate until the battery cell film 02 is completely torn; in the process, the supporting member 57 is used for supporting the torn-off cell film 02.
In the process of tearing off the cell membrane 02, the action is required to be executed simultaneously by matching the membrane separating component 5 with the rotary clamping component 4. Since the "tear-off" process has two implementations: firstly, the battery cell 01 rotates in a fixed shaft way, and the tearing part 03 is fixed and retreats; second, the tear-off portion 03 is fixed, and the cell 01 is rotated while retreating is performed. In the implementation process of the former, more action execution space needs to be reserved, and a mechanism for realizing the fixed axis rotation of the battery cell 01 and a mechanism for realizing the transverse movement of the membrane separation assembly 5 need to be additionally arranged. This clearly increases the length in the direction of action execution for the device as a whole, and also reduces the degree of co-ordination between the components. In the present embodiment, the rotary clamping assembly 4 performs the functions of fixing, transferring, rotating and retracting, so that the integration level is high, the membrane separation assembly 5 does not need to perform long-distance transverse movement, and the coordination degree of the membrane separation process is high.
When the cell film 02 is torn off, it has a four-layer structure, as shown in fig. 10, the positive electrode material 021, the lower separator 022, the negative electrode material 023 and the upper separator 024 are respectively arranged from bottom to top. Therefore, the positive electrode material 021, the lower diaphragm 022 and the negative electrode material 023 are required to be peeled in sequence, and then four layers of materials are separated; during the whole process, the cell membrane 02 needs to be pulled by the traction component 6.
As shown in fig. 11, the traction assembly 6 includes a traction guide rail 61 and a traction clamping jaw 62, and in combination with fig. 1, the traction guide rail 61 is disposed at the side of each assembly along the distribution direction of the membrane separation assembly 5, the positive electrode material separation assembly 7a, the membrane separation assembly 8, the negative electrode material separation assembly 7b, and the coil assembly 9; the pulling jaw 62 pulls the cell film to the station where each component is located in turn.
The positive electrode material separating component 7a and the negative electrode material separating component 7b have the same structure, and as shown in fig. 12-14, each include a scraping member 71 below the membrane structure and a pressing member 72 above the membrane structure; as shown in fig. 13, the scraping member 71 includes a scraping blade 711, a first roller 712, and a second roller 713, which are sequentially provided in the film structure moving direction; the scraper 711 is provided in an inclined direction and has a scraper head portion at the highest position; as shown in fig. 12, the pressing member 72 includes a pressing plate 721 and a third roller shaft 722, and can be lifted and lowered; as shown in fig. 14, the pressing plate 721 is abutted against the upper end surface of the film structure in the working state, and the height of the upper end surface of the film structure at the corresponding position is lower than the height of the scraping head part; the third roller shaft 722 and the first roller shaft 712 are distributed in the vertical direction, and the film feeding structure is arranged between the first roller shaft 712 and the third roller shaft 722 in a penetrating manner in the working state.
In the working state, the traction component 6 moves to one side of the membrane separation component 5, clamps the tearing part 03, and pulls the membrane structure to move along the length direction perpendicular to the scraping component 71; as shown in fig. 14, the film structure always moves in contact with the blade 711, and the lowermost positive electrode material is scraped off by the blade 711; similarly, after the lower separator is separated, the membrane structure moves to the side of the negative electrode material separating component 7b, and the negative electrode material can be scraped off by pulling of the traction component 6.
As shown in fig. 13, 15, 16, the membrane separation assembly 8 includes a lower suction member 81 located below the membrane structure, and an upper suction member 82 located above the membrane structure, the upper suction member 82 being displaced in the horizontal direction with respect to the lower suction member 81. As shown in fig. 13, the lower suction member 81 employs one or more lower suction cups for sucking the lower surface (lower diaphragm) of the membrane structure; as shown in fig. 15, the upper suction member 82 employs one or more upper suction cups for sucking the upper surface (upper diaphragm) of the membrane structure, and can be lifted and horizontally moved. As shown in fig. 16, when the upper adsorption member 82 adsorbs the upper separator to move laterally, the lower adsorption member 81 is fixed, so that the upper separator and the lower separator can be separated, and the negative electrode material can be leaked. In this process, the tearing off of the lower diaphragm is completed.
In the present embodiment, as shown in fig. 13, the scraping member 71 and the lower suction member 81 are integrally provided, and the lower suction member 81 is provided between the first roller shaft 712 and the second roller shaft 713, so that the scraping member and the lower suction member can be lifted. Further, the positive electrode material separation unit 7a, the separator separation unit 8, and the negative electrode material separation unit 7b have the same device structure below the membrane structure.
