[0002] The charging and discharging speed of lithium-ion batteries is determined by the transmission and deintercalation speed of lithium ions in the electrodes. Graphene has excellent electronic and ion conductivity and a special two-dimensional single-atomic layer structure, which can form a three-dimensional electronic and ion transmission network structure between electrode material particles. Therefore, compared with traditional lithium batteries, graphene lithium batteries have extremely high charging and discharging speeds.

[0053] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0054] like Figure 1-17 As shown, the present invention has the following four specific embodiments.

[0055] Example 1

[0056] A gluing device for a graphene lithium battery cell cover, comprising a battery cell body A and a positive electrode battery cover B, wherein one end of the battery cell body A is provided with a positive electrode head A1, and further comprising:

[0057] The transfer mechanism includes a fixed cylinder 11 and a transfer roller 12. A feed port 13 is provided on the left side of the fixed cylinder 11, and a drop port 14 is provided on the front side of the bottom plate of the fixed cylinder 11. The transfer roller is rotatably connected to the fixed cylinder 11, and transfer grooves 15 are symmetrically provided on the left and right sides of the transfer roller 12.

[0058] A first conveying mechanism is provided on the left side of the fixing cylinder 11 and is used for conveying the battery cell body A;

[0059] The second conveying mechanism 3 is provided on the upper right side of the fixed cylinder 11 and is used for conveying the positive battery cover B;

[0060] The moving mechanism includes a seat plate 41, a moving seat 42 and a mounting seat 43; the seat plate 41 is fixed to the right side of the second conveying mechanism 3, and a moving groove 44 is opened on the seat plate 41. A guide rod 45 is fixedly connected to the moving groove 44 symmetrically in the front and back. The moving seat 42 is located in the moving groove 44 and is slidably connected to the guide rod 45. The upper surface of the moving seat 42 is evenly fixed with L-shaped support rods 46 in the longitudinal direction. The mounting seat 43 is fixed to the head of the support rod 46;

[0061] The pressing mechanism 5 is arranged on the lower surface of the seat plate 41. When the movable seat 42 contacts the left side of the movable groove 44, the pressing mechanism 5 is located directly above the right transfer groove 15. When the movable seat 42 contacts the right side of the movable groove 44, the pressing mechanism 5 is located directly above the second conveying mechanism 3.

[0062] The driving mechanism is used to drive the transfer roller 12 to rotate intermittently 180 degrees. The driving mechanism is also used to drive the movable seat 42 to move back and forth left and right. When the transfer roller 12 rotates 180 degrees, the movable seat 42 performs a reciprocating left and right motion stroke;

[0063] The gluing mechanism 7 is located at the rear side of the fixed cylinder 11 and is used to complete the gluing operation on the positive electrode A1 during the rotation process.

[0064] In this embodiment:

[0065] In this device, the fixed cylinder 11 is suspended and installed by an external bracket.

[0066] like Figure 2-3 As shown, in the initial state, the transfer trough 15 on the left is aligned with the feed port 13, and the first conveying mechanism conveys the battery cell body A from left to right. During the conveying process, since the present invention illustrates the working principle of the device through the gluing of the positive battery cover B, the positive head A1 of each battery cell body A faces upward. When gluing the negative battery cover, the positive head A1 of the battery cell body A can be conveyed downward.

[0067] The transported battery cell body A enters the transfer trough 15 on the left through the feed port 13. At this time, under the action of the driving mechanism, the transfer roller 12 performs an intermittent 180° rotation. The driving direction of the driving mechanism is set so that when viewed from top to bottom, the transfer roller 12 rotates clockwise, and the battery cell body A passes through the gluing mechanism 7 on the rear side, and the gluing mechanism 7 coats the positive electrode head A1 with glue.

[0068] After the transfer roller 12 rotates 180 degrees, the battery cell body A on the left is transferred to the gluing position on the right.

[0069] When the transfer roller 12 rotates, the movable seat 42 moves synchronously. In the initial state, the movable seat 42 contacts the left side of the movable groove 44. During the rotation of the transfer roller 12, the driving mechanism also drives the movable seat 42 to move. The movable seat 42 first moves to the right. When the movable seat 42 contacts the right side of the movable groove 44, the pressing mechanism 5 is located directly above the second conveying mechanism 3 to load the positive battery cover B. Then the movable seat 42 moves to the left and resets. When the movable seat 42 contacts the left side of the movable groove 44, the battery body A just reaches the processing position, and the pressing mechanism 5 works to glue the positive battery cover B to the top of the battery body A.

[0070] Then the driving device continues to work, and transfers the battery cell body A to be glued on the left to the right. The glued battery cell body A on the right rotates clockwise with the transfer roller 12, and falls when it passes the drop port 14. A collection box can be set below the drop port 14 to collect the glued battery cell body A, so that the transfer trough 15 at this position is empty. When it reaches the left side, it can take on a new battery cell body A. This cycle can realize the fully automatic gluing of the positive battery cover B.

[0071] As a further implementation of this embodiment, the first conveying mechanism includes a U-shaped frame 21, a first conveying roller 22 and a first conveying motor 23; the U-shaped frame 21 is fixed to the left side of the fixed cylinder 11, the opening of the U-shaped frame 21 is aligned with the feed port 13, and a groove is provided on the front and rear side plates of the U-shaped frame 21. A first conveying shaft 24 is connected to each groove body for symmetrical rotation. The bottoms of the two conveying shafts on the left are fixed with driven wheels 25. The first conveying roller 22 is fixed to the first conveying shaft 24. The two first conveying rollers 22 on the front side and the two first conveying rollers 22 on the rear side are respectively linked by a first conveyor belt 26. The outer surface of the first conveyor belt 26 A rubber pad 27 is fixed to the wall, and the first conveying motor 23 is fixed to the bottom of the U-shaped frame 21 through the frame. A driving gear 28 is fixed to the power shaft of the first conveying motor 23. The bottom of the U-shaped frame 21 is also rotatably connected to a rotating shaft 29, and a driven gear 310 is fixed to the rotating shaft 29. The driven gear 310 is engaged with the driving gear 28. A driving wheel 211 corresponding to the driven wheel 25 is fixed to the power shaft of the first conveying motor 23 and the rotating shaft 29. The corresponding driving wheel 211 and the driven wheel 25 are linked by a third belt 212. The distance between the front and rear rubber pads 27 on the side close to each other is less than the diameter of the battery body A.

[0072] In this embodiment:

[0073] like Figure 14 As shown, when the first conveying motor 23 is working, it drives the driving gear 28 and the driving wheel 211 on the rear side to rotate. The driving gear 28 also drives the driven gear 310 and the rotating shaft 29 to rotate, so that the driving wheel 211 on the front side rotates. Since the externally meshed driving gear 28 and the driven gear 310 rotate in opposite directions, the two driving wheels 211 rotate in opposite directions. Under the action of the third belt 212, the two driven wheels 25 rotate in opposite directions. The direction of the first conveying motor 23 is set so that when viewed from top to bottom, the driven wheel 25 on the rear side rotates counterclockwise and the driven wheel 25 on the front side rotates clockwise, so that the first conveyor belts 26 on the front and rear sides rotate clockwise and counterclockwise, respectively.

[0074] The cell body A sandwiched between the rubber pads 27 is transported from left to right.

[0075] like Figure 15 As shown, since the distance between the two front and rear rubber pads 27 on their sides close to each other is smaller than the diameter of the cell body A, the cell body A is clamped between the rubber pads 27, making the transportation of the cell body A more reliable.

[0076] As a further implementation of this embodiment, the second conveying mechanism 3 includes a conveying seat 31, a second conveying roller 32 and a second conveying motor 33; the conveying seat 31 is fixedly connected to the right side of the fixed cylinder 11, the seat plate 41 is fixedly connected to the conveying seat 31, and the baffle 34 is fixedly connected to the left and right sides of the rear side of the conveying seat 31 symmetrically. A second conveying roller 32 is rotatably connected inside the conveying seat 31 and between the rear ends of the baffle 34 through a second conveying shaft 35, and the two second conveying rollers 32 are linked by a second conveyor belt 36. The second conveying motor 33 is fixed to the outer wall of the baffle 34, and the power shaft of the second conveying motor 33 is docked with the second conveying shaft 35 on the rear side. The upper surface of the conveying seat 31 is fixed with a positioning seat 37.

[0077] In this embodiment:

[0078] like Figure 16 and 17 As shown, when the second conveying motor 33 is working, it drives the second conveying belt 36 to rotate. The direction of the second conveying motor 33 is set so that the positive battery cover B thereon is conveyed from back to front and the positive battery cover B is positioned by the positioning seat 37.

[0081] Preferably, there are four locking slots 615 and four shifting slots 616, and the diameter of the first driving wheel 618 is twice the diameter of the first transmission wheel 620;

[0082] The diameter of the second driving wheel 619 is twice the diameter of the second driving wheel 619. Assuming that the ratio of the number of teeth of the worm wheel 68 to the number of heads of the worm 64 is i, when the movable seat 42 moves from the leftmost side to the rightmost side, the number of rotations of the reciprocating screw 61 is N, then i=4N.

[0083] In this embodiment:

[0084] like Figure 5-8 As shown, when the driving motor 62 rotates, it drives the dial 610, the tray 611 and the dial rod 613 to rotate synchronously. When the dial rod 613 does not enter the dial groove 616, the dial 610 and the locking groove 615 rotate. At this time, the groove wheel 614 does not rotate. When the dial rod 613 enters the dial groove 616, it drives the groove wheel 614 to rotate. At this time, the head of the groove wheel 614 enters the transition groove 612.

[0085] That is, each time the driving motor 62 rotates one circle, the sheave 614 rotates a fixed angle.

[0086] Since there are four locking grooves 615 and four shifting grooves 616, the groove wheel 614 rotates 90° every time the driving motor 62 rotates one circle, that is, the groove wheel 614 rotates 90° intermittently, and when the groove wheel 614 rotates, it drives the second shaft 63 to rotate. When the second shaft 63 rotates, the first driving wheel 618 rotates. The first driving wheel 618 drives the first transmission wheel 620, the third shaft 617 and the transfer roller 12 to rotate through the first belt 621. Since the diameter of the first driving wheel 618 is twice the diameter of the first transmission wheel 620, the rotation speed of the first transmission wheel 620 is twice that of the first driving wheel 618, that is, when the first driving wheel 618 rotates 90°, the first transmission wheel 620 and the transfer roller 12 rotate 180°, thereby realizing the intermittent 180° rotation of the transfer roller 12.

[0087] When the second shaft 63 rotates, it also drives the second drive wheel 619 to rotate. The second drive wheel 619 drives the second transmission wheel 622, the first shaft 67 and the worm gear 68 to rotate synchronously through the second belt 623. The worm gear 68 drives the worm 64 and the reciprocating screw 61 to rotate. Since the movable seat 42 is engaged with the reciprocating screw 61 through the reciprocating threaded sleeve in the center and is limited by the guide rod 45, when the reciprocating screw 61 rotates, the movable seat 42 moves back and forth left and right.

[0088] Since the second shaft 63 rotates intermittently, the transfer roller 12 and the movable seat 42 are both driven by the second shaft 63 , that is, the transfer roller 12 and the movable seat 42 move synchronously.

[0089] Since the ratio of the number of teeth of the worm wheel 68 to the number of teeth of the worm 64 is i, that is, when the worm wheel 68 rotates one circle, the worm 64 and the reciprocating screw 61 rotate i circles, and the diameter of the second driving wheel 619 is twice the diameter of the second transmission wheel 622, that is, when the second driving wheel 619 rotates one circle, the second transmission wheel 622 rotates 2 circles, that is, when the second driving wheel 619 rotates one circle, the worm wheel 68 rotates two circles. Since the second driving wheel 619 rotates intermittently by 90 degrees, the second driving wheel 619 rotates 90 degrees every time (i.e. 0.25 turns), the worm wheel 68 rotates (0.25*2) turns, the worm 64 rotates (0.25*2*i) turns, and since the number of turns of the reciprocating screw 61 is N when the movable seat 42 moves from the leftmost side to the rightmost side, it is assumed that in the initial state, the movable seat 42 is in contact with the left side of the movable groove 44, that is, when the movable seat 42 moves to the right to contact the right side of the movable groove 44 and then resets, the number of turns of the reciprocating screw 61 is 2N, so 0.25*2*i=2N, that is, i=4N.

[0090] That is, the driving mechanism can realize the intermittent 180° rotation of the transfer roller 12. During the 180° rotation of the transfer roller 12, the movable seat 42 first moves to the right, so that the pressing mechanism 5 moves to the top of the second conveying mechanism 3 to load the positive battery cover B, and then moves to the left to reset, so that the pressing mechanism 5 is located directly above the battery cell body A to be glued.

[0091] During specific operation, there is a battery cell body A to be glued (recorded as battery cell No. 1) in the transfer trough 15 on the left side of the right side, and there is a glued battery cell body A (recorded as battery cell No. 2) in the transfer trough 15 on the right side. When the device is working, it first rotates 180° clockwise, and the No. 1 battery cell is glued by the gluing mechanism, and then moved to the right and braked for a period of time. The No. 2 battery cell rotates clockwise and falls at the drop port 14, so that the controlled transfer trough 15 moves to the left. When the transfer roller 12 rotates, the movable seat 42 performs a reciprocating left and right movement to load and reset the positive battery cover B, and then brake.

[0092] When the movable seat 42 and the transfer roller 12 are braked, the pressing mechanism 5 works to glue the positive electrode battery cover B.

[0093] Then the transfer roller 12 and the movable seat 42 continue to move, and this cycle is repeated to continuously achieve the gluing of the battery cell body A and the positive electrode battery cover B.

The inlet of the negative pressure fan 54 is connected to the cover body 57 through the ventilation component. When the push rod 55 is in the maximum telescopic state, the lower surface of the pressure seat 52 contacts the upper surface of the transfer roller 12.

[0096] Preferably, the ventilation assembly includes a ventilation chamber 531 and a valve seat 532; the ventilation chamber 531 is fixedly connected to the left side of the cover body 57 and communicates with the cover body 57, a pair of first partitions 533 are fixedly connected in the ventilation chamber 531, and the first partitions 533 are symmetrically provided with first through holes 534 and second through holes 535 on the upper and lower sides, a second partition 536 is fixedly connected between the left first partition 533 and the left side plate of the ventilation chamber 531, and a third through hole 536 is provided on the left side plate of the ventilation chamber 531 below the second partition 536. 7. A suction pipe 538 is fixedly connected to the inlet of the negative pressure blower 54. The suction pipe 538 is connected to the top plate of the ventilation chamber 531. The connection between the suction pipe 538 and the ventilation pipe is located above the second partition plate 536. The valve seat 532 is slidably connected between the first partition plates 533. A support rod 539 is fixedly connected to the lower surface of the valve seat 532. The support rod 539 is slidably connected to the bottom plate of the ventilation chamber 531. The bottom of the support rod 539 is fixedly connected to a contact seat 5310. A spring 5311 is sleeved on the outer surface of the support rod 539.

[0097] When the valve seat 532 contacts the bottom plate of the ventilation chamber 531, the spring 5311 is in a natural state, and at this time the distance between the bottom surface of the contact seat 5310 and the bottom surface of the pressure seat 52 is equal to the distance between the upper surface of the valve seat 532 and the top plate of the ventilation chamber 531.

[0098] Preferably, a support plate 511 is fixedly connected to the front side of the movable seat 42, an infrared receiver 512 is fixedly connected to the support plate 511, an infrared transmitter 513 is fixedly connected to the front side of the seat plate 41, the infrared receiver 512 and the infrared transmitter 513 are used in pairs, and when the movable seat 42 contacts the left side of the movable slot 44, the infrared receiver 512 and the infrared transmitter 513 are aligned, and a PLC controller 514 and a time relay 515 are fixedly connected to the front side of the fixed cylinder 11, the power interface of the PLC controller 514 is electrically connected to the external power supply, the signal input end of the PLC controller 514 is electrically connected to the infrared receiver 512, the control output end of the PLC controller 514 is electrically connected to the electric cylinder 51 through the time relay 515, and an air pressure sensor 516 is fixedly connected in the cover body 57, the air pressure sensor 516 is electrically connected to the signal input end of the PLC controller 514, and the control output end of the PLC controller 514 is also electrically connected to the negative pressure fan 54.

[0099] In this embodiment:

[0100] like Figure 9 and 10As shown, the negative pressure fan 54 continues to work and draws air to the cover body 57 through the ventilation component. Under the action of the suction hole 58, the receiving groove 56 forms a negative pressure. When the pressing mechanism 5 moves to the top of the second conveying mechanism 3, the positive battery cover B is sucked up by the negative pressure and enters the receiving groove 56. Then the pressing mechanism 5 moves to the processing position, and the electric cylinder 51 drives the push rod 55 to extend, so that the pressure seat 52 descends, and the positive battery cover B is pressed onto the top of the battery body A.

[0101] A pressure sensor 516 is provided in the cover body 57 . The pressure sensor 516 detects the air pressure in the cover body 57 and compares it with a threshold value preset in the PLC controller 514 . When the detected value is greater than the threshold value, the circuit of the negative pressure fan 54 is cut off.

[0102] like Figure 9 As shown, when gluing is not completed, under the action of the spring 5311, the valve seat 532 contacts the bottom of the ventilation chamber 531. At this time, the suction tube 538 draws air through the first through hole 534, thereby forming a negative pressure environment in the cover body 57 (according to Bernoulli's principle, fast-flowing airflow forms negative pressure).

[0103] like Figure 10 As shown, during the pressing process, the contact seat 5310 contacts the transfer roller 12, so that the valve seat 532 is pushed up, the first through hole 534 is closed, and the outside air is connected to the internal environment of the cover body 57 through the third through hole 537 and the second through hole 535, so that the glued positive battery cover B is separated from the receiving groove 56.

[0104] like Figure 11 and 12 As shown, when the movable seat 42 contacts the left side of the movable groove 44, the positive battery cover B and the battery cell body A are in place. At this time, the infrared receiver 512 is aligned with the infrared transmitter 513, and the infrared receiver 512 receives the signal and transmits it to the PLC controller 514. The PLC controller 514 controls the electric cylinder 51 to perform a reciprocating extension and contraction movement through the time relay 515, completing a pressing operation, thereby realizing automatic control of the electric cylinder 51.

[0109] During the transportation of the battery cell body A, the positive electrode head A1 contacts the rubber-coated sponge 72. Under the action of friction, the battery cell body A and the positive electrode head A1 rotate, so that the circumference of the positive electrode head A1 can be coated with rubber.
