Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of battery cell processing, and particularly relates to a battery cell flattening device for lithium battery production and processing. BACKGROUND

[0002] A lithium ion battery is a kind of secondary battery, which mainly relies on lithium ions to move between the positive electrode and the negative electrode to work. During the charging and discharging process, Li+ embeds and de-embeds between the two electrodes. When charging, Li+ de-embeds from the positive electrode, embeds into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state. When discharging, the opposite is true. Lithium batteries are divided into lithium batteries and lithium ion batteries. Mobile phones and notebook computers use lithium ion batteries, which are commonly known as lithium batteries. Lithium batteries need to be flattened during production.

The supports of the battery cell flattening machine are symmetrically welded at the top end of the long side seat of the chain plate conveyor, and the seat inside the chain plate conveyor is provided with a rotatable chain plate conveyor belt through a shaft body. The surface of the belt plate of the chain plate conveyor belt is provided with a limit seat, and the outer surfaces of the two end seat plates of the limit seat are symmetrically welded with ear plates, and the ear plates and the belt plate of the chain plate conveyor belt are locked with bolts. The outer surfaces of the long side seat plates on both sides of the chain plate conveyor below the battery cell flattening machine are symmetrically provided with split grooves, and the supporting plates are embedded between the split grooves. The supporting plates pass through the loop-shaped belt bodies of the chain plate conveyor belt, and the two ends of the supporting plates are welded with lifting plates which protrude out of the split grooves. The outer seat surface of the chain plate conveyor below the lifting plate is welded with a base plate, and the surface of the base plate is locked with the bottom of the electric push rod through bolts. The telescopic rod head of the electric push rod is locked with a fastening bolt between the lifting plate.

[0040] When embedding, the embedding end 611 on the connecting column 61 is embedded into the embedding groove 62 through the outer cover 63 and the movable pipe 64; at this moment, the constraint unit 65 in the movable pipe 64 is buckled on the circular truncated cone end 612; the rotating pipe 66 is rotated by pulling the pulling bar 632; the rotating pipe 66 pulls the movable pipe 64 to move towards the embedding groove 62; then the constraint unit 65 pulls the embedding end 611 to be embedded into the embedding groove 62 through the circular truncated cone end 612; at this moment, the check unit 67 restrains the pulling bar 632, so that the movable pipe 64 and the constraint unit 65 cannot move outward, thereby enhancing the firmness of the connection between the connecting column 61 and the embedding groove 62.

[0041] Referring to Figure 3 , the connecting column 61 is made of an iron column; the bottom wall of the embedding groove 62 is fixed with a magnet A621 for attracting the embedding end 611 on the connecting column 61.

[0042] The magnet A621 can attract the connecting column 61, thereby realizing the purpose of pre-fastening and facilitating assembly.

[0043] Referring to Figure 3 and Figure 4 , the constraint unit 65 comprises a constraint pipe 651 surrounded by a pair of semicircular pipes 6511 and a connecting part 652 for connecting or disassembling the pair of semicircular pipes 6511; the axis of the constraint pipe 651 coincides with the axis of the movable pipe 64; the movable pipe 64 is reserved with a constraint opening 641 for moving the pair of semicircular pipes 6511; the constraint pipe 651 is buckled on the circular truncated cone end 612.

[0044] In the process of performing the embedding, the pair of half-round tubes 6511 is disassembled via the adapter 652, and after the embedding end 611 passes through the pair of half-round tubes 6511 and is embedded into the embedding groove 62, the pair of half-round tubes 6511 is then assembled into a complete constraint tube 651 via the adapter 652, at which time the constraint tube 651 is just positioned on the round table end 612, greatly enhancing the convenience during use.

[0045] Referring to Figure 3 With Figure 4 , the adapter 652 includes a pressing rod 6521, a linkage strip 6522, a variable column 6523, a receiving cover 6524, and an elastic member B 6525; the movable tube 64 has a pressing opening 642 reserved therein for the back-and-forth movement of the lower end of the pressing rod 6521, and the outer surface of the outer cover 63 has a movable opening 633 reserved for the passage of the pressing rod 6521, the pressing rod 6521 and the movable opening 633 being movably connected, and the pressing opening 642 and the movable opening 633 being connected; the constraint opening 641 has a receiving opening 643 reserved thereon, the linkage strip 6522 is provided in a pair and is positioned in the receiving opening 643, the variable column 6523 is provided in a pair and is respectively fixed to the back surface of the half-round tube 6511, the linkage strip 6522 is rotatably connected to the pressing rod 6521 on one side and is rotatably connected to the corresponding variable column 6523 on the other side; the receiving cover 6524 is provided in a pair and is respectively connected to the two sides of the movable tube 64, and the outer cover 63 has a channel 634 reserved therein for the movement of the receiving cover 6524 therein; the variable column 6523 is movably arranged between the constraint opening 641 and the receiving cover 6524; the elastic member B 6525 is provided in a pair and is arranged in the corresponding receiving cover 6524, and when the pair of half-round tubes 6511 is connected to form the constraint tube 651, the elastic member B 6525 is in a shortened state.

[0046] When the pair of half-round tubes 6511 is connected to form the constraint tube 651, the elastic member B 6525 is in a shortened state, which can enhance the stability of the pair of half-round tubes 6511 after being connected to form the constraint tube 651, and in turn enhance the stability of the constraint tube 651 when pressing the round table end 612.

[0047] During the insertion process, the pressure rod 6521 is pressed downwards. The pressure rod 6521 pulls a pair of movable columns 6523 towards the inside of a pair of storage covers 6524 via a pair of linkage bars 6522, thereby causing a pair of semi-circular tubes 6511 to move away from each other, allowing the insertion end 611 of the connecting column 61 to pass through. At this moment, the elastic element B6525 is in a shortened state. After the insertion end 611 is inserted into the insertion groove 62, the pressure rod 6521 is released. The pair of elastic elements B6525 pulls the corresponding movable columns 6523, linkage bars 6522, and pressure rod 6521 back to their original positions, allowing the pair of semi-circular tubes 6511 to form a constraint tube 651 clamped on the frustum end 612. This facilitates the disassembly or docking of the pair of semi-circular tubes 6511, and the storage cover 6524 is used to allow the movement of the movable columns 6523 and the movement of the elastic element B6525. At the same time, it can cooperate with the channel 634 to guide the movement of the movable tube 64.

[0048] Reference Figure 3 and Figure 4 An elastic element A6421, which is fixed to one side of the pressure rod 6521, is installed in the pressure port 642. The elastic element A6421 is always in a shortened state.

[0049] The installation of elastic element A6421 can cooperate with elastic element B6525 to jointly enhance the return function of pressure rod 6521, linkage bar 6522 and variable column 6523.

[0050] Reference Figure 3 and Figure 4 The ends of a pair of semi-circular tubes 6511 are fixed to magnets B65111 that attract each other.

[0051] The installation of magnet B65111 can enhance the stability after the connection of a pair of semi-circular tubes 6511, thereby enhancing the stability when the constraint tube 651 pulls the frustum end 612 to move; and the magnet B65111, which attract each other, can assist the return of the moving column 6523, the linkage bar 6522 and the pressure rod 6521 when the pair of semi-circular tubes 6511 are about to form the constraint tube 651.

[0052] Reference Figure 4 An inserting post 635 is fixedly connected to the side wall of the channel 634 near the inserting groove 62. The storage cover 6524 and the movable post 6523 have pre-reserved inserting interfaces 6351 for inserting the inserting post 635. When the rotating tube 66 pulls the movable tube 64 toward the inserting groove 62, the inserting post 635 is inserted into the inserting interface 6351 on the corresponding movable post 6523.

[0053] When the levering lever 632 is levered to make the rotating tube 66 pull the movable tube 64 to change, the embedded column 635 is embedded into the embedded interface 6351 on the changing column 6523, at this moment, the embedded column 635 can not only guide the changing of the receiving cover 6524 and the movable tube 64, but also can lock the position of the changing column 6523 in the receiving cover 6524, thereby enhancing the stability of the pair of semicircular tubes 6511 when extruding the circular table end 612.

[0054] With reference to Figure 3 With Figure 5 , the non-return unit 67 comprises a stopper block 671, an arch-shaped protruding block 672, a disassembling part 673 and a maintaining part 674; the stopper block 671 is arranged on the levering lever 632, the arch-shaped protruding block 672 is fixedly connected to the inner surface of the rotating opening 631, when the stopper block 671 and the arch-shaped protruding block 672 are engaged, the rotation of the levering lever 632 and the rotating tube 66 can only pull the movable tube 64 to change to one side of the embedded slot 62; the disassembling part 673 is arranged on the levering lever 632 and is used to pull the stopper block 671 and the arch-shaped protruding block 672 to unlock; the maintaining part 674 is arranged on the levering lever 632, and is used to maintain the position of the stopper block 671 constant when the stopper block 671 and the arch-shaped protruding block 672 are unlocked.

[0056] When the connecting column 61 is disassembled, the stopper block 671 and the arch-shaped protruding block 672 are disengaged through the disassembling part 673, at this moment, the levering lever 632 can be reversed, the rotating tube 66 pulls the movable tube 64 to change to the farther side of the embedded slot 62, then the pair of semicircular tubes 6511 are disengaged through the connecting part 652, the connecting column 61 can be pulled out, thereby greatly enhancing the convenience of disassembling the connecting column 61.

[0057] With reference to Figure 3 With Figure 5 , the disassembling part 673 comprises a clamping cylinder 6731 and an elastic member C6732, the clamping cylinder 6731 is movably clamped on the levering lever 632, the elastic member C6732 is arranged in the clamping cylinder 6731 and is fixedly connected with the levering lever 632; the stopper block 671 is rotatably connected to the clamping cylinder 6731.

[0058] When the connecting column 61 is disassembled, the pressing hoop 6731 makes the stopper 671 and the arch-shaped protrusion 672 disintegrate, the elastic member C 6732 is shortened, and the hoop 6731 is reversely twisted to make the twisting bar 632 and the rotating tube 66 pull the movable tube 64 to move away from the side of the embedding groove 62, so as to ensure the disintegration of the stopper 671 and the arch-shaped protrusion 672 and improve the convenience of the reverse twisting of the twisting bar 632.

[0059] With reference to Figure 5 With Figure 6 , the maintaining part 674 comprises a maintaining block 6741 and an elastic member D 6742, the maintaining block 6741 is fixedly connected to the hoop 6731, and the elastic member D 6742 is fixedly connected between the maintaining block 6741 and the stopper 671; when the stopper 671 and the arch-shaped protrusion 672 are engaged, the elastic member D 6742 is in a normal state.

[0060] When the hoop 6731 pulls the stopper 671 and the arch-shaped protrusion 672 to disintegrate, the elastic member D 6742 can maintain the orientation of the stopper 671 constant, so that after the hoop 6731 is released, the elastic member C 6732 pulls the hoop 6731 back to the original position, the stopper 671 can be engaged with the arch-shaped protrusion 672 again, and the use is very convenient.
