[0067] When in use, the controller automatically controls the material receiving drive motor 608 to work, and the output shaft of the material receiving drive motor 608 drives the drive screw 606 to rotate through the coupling.

[0075] A U-shaped fixed protective frame 618 is fixedly connected to the upper surface of the belt pressing plate 617. A guide groove 619 with a T-shaped inner wall is provided on the upper surface of the fixed protective frame 618. The two guide grooves 619 are symmetrically distributed with the axis of the fixed protective frame 618 as the center. A laser beam sensor 620 electrically connected to the controller via a cable is fixedly installed on the inner wall of the fixed protective frame 618.

[0076] When in use, the laser beam sensor 620 is used to detect the position of the electrolyte barrel moving to the fixed protective frame 618, so as to automatically control the electrolyte barrel conveyor belt 602 to stop working after the electrolyte barrel moves to the position.

[0083] The electric push rod 628 is electrically connected to the controller via a cable.

[0084] Furthermore, in order to achieve better control and power supply for the electrolyte barrel conveying mechanism, during actual use, a drag chain cable is arranged inside the lifting tower 1, and the surface of the drag chain cable is fixed to the surface of the lifting bracket 4, so that the electrolyte barrel conveying mechanism has stable power supply and control signal transmission during operation, and the surface of the lifting bracket 4 is X-shaped, which is convenient for avoiding the drag chain cable, thereby achieving a better power supply effect.

[0085] Preferably, the surface of the lifting bracket 4 and the inner wall of the supporting bottom frame 6 are also provided with a drag chain cable or a spring wire for providing power to the docking material drive motor 608, the conveying drive motor 610 and the electric push rod 628.

[0086] By setting up an electrolyte barrel conveying mechanism, when in use, the electrolyte barrel conveyor belt 602 cooperates with the assembly line conveyor belt 3 to automatically move the battery electrolyte barrel into the elevator, and during the movement, the movable protective frame 622 and the barrel support frame 627 cooperate to protect and support the battery barrel, ensuring that the battery electrolyte safely enters the elevator, and after lifting, the electrolyte barrel conveyor belt 602 is driven by the rotating drive motor 62 to rotate in the direction of docking with the elevator set in the filling workshop, so that the battery electrolyte barrel automatically enters the filling workshop from the cleaning and drying workshop.

[0087] By setting up a lifting drive mechanism and an electrolyte barrel conveying mechanism, when in use, the lifting drive mechanism and the electrolyte barrel conveying mechanism are automatically controlled by a controller to work, and the electrolyte barrel conveyor belt 602 is driven by the lifting drive mechanism. After moving to be level with the assembly line conveyor belt 3, the electrolyte barrel conveyor belt 602 moves in the same direction as the assembly line conveyor belt 3, and the electrolyte barrel is moved from the assembly line conveyor belt 3 to the electrolyte barrel conveyor belt 602 and enters the lifting tower 1. Then, after the electrolyte barrel conveyor belt 602 is separated from the assembly line conveyor belt 3 and reset, the battery electrolyte barrel is lifted from the cleaning and drying workshop into the filling workshop by the lifting drive mechanism, thereby solving the problem that the elevator cannot automatically cooperate with the conveyor belt to complete the lifting and transportation, and there are low automation levels and high labor costs.

[0088] Working principle: In the process of lifting and transporting the electrolyte barrels in the cleaning workshop to the filling workshop, the lifting drive mechanism first drives the lifting bracket 4 and the electrolyte barrel conveying mechanism to move downward in the lifting tower 1, so that the surface of the electrolyte barrel conveyor belt 602 in the electrolyte barrel conveying mechanism moves to be flush with the surface of the assembly line conveyor belt 3.

[0089] Specifically, the controller controls the lifting drive motor 503 to work, and the lifting drive motor 503 drives the driving shaft to rotate in the opposite direction, and the driving shaft drives the driving gear 504 to rotate. The driving gear 504 drives four driven gears 506 to rotate through four transmission gears 505 at the same time, and drives four driving screws 501 to rotate synchronously. Through the synchronous rotation of the four driving screws 501, the lifting bracket 4 and the electrolyte barrel conveying mechanism on the lifting bracket 4 are driven to move downward. In actual use, according to the height of the assembly line conveyor belt 3, a limit switch or a proximity sensor is installed inside the lifting tower 1, and is connected to the controller through the limit switch or the proximity sensor. During the lifting movement of the lifting bracket 4, after the surface of the lifting bracket 4 contacts the limit switch or approaches the proximity sensor, the limit switch or the proximity sensor sends an electrical signal to the controller for feedback. After receiving the feedback signal, the controller controls the lifting drive motor 503 to stop forward or reverse rotation, and performs limit control on the stroke of the lifting bracket 4 to achieve the effect of precise control.

[0090] After the surface of the electrolyte barrel conveyor belt 602 in the electrolyte barrel conveying mechanism moves to be flush with the surface of the assembly line conveyor belt 3, the controller controls the material receiving drive motor 608 to work, and the output shaft of the material receiving drive motor 608 drives the driving screw 606 to rotate through the coupling, and the driving screw 606 thread drives the driving block 607 to move, driving the conveying support frame 601 on the upper surface of the supporting bottom frame 6, along the guide slide rail 604 to move, driving the supporting bottom frame 6 and the electrolyte barrel conveyor belt 602 to move close to one end of the assembly line conveyor belt 3, and the conveying support frame 601 is limited by the limit switch 609 to ensure that after the electrolyte barrel conveyor belt 602 is close to the assembly line conveyor belt 3, the electrolyte barrel can be smoothly transported to the electrolyte barrel conveyor belt 602 through the assembly line conveyor belt 3.

[0091] Then the controller controls the conveying drive motor 610 to work, the conveying drive motor 610 drives the active synchronous pulley 611 to rotate forward, the active synchronous pulley 611 drives the driven synchronous pulley 613 to rotate through the synchronous belt, the driven synchronous pulley 613 drives the conveying drive shaft 612 to rotate, the conveying drive shaft 612 drives the driving roller 614 to rotate, and drives the electrolyte barrel conveyor belt 602 to rotate in the direction of the assembly line conveyor belt 3.

After moving to the electrolyte barrel on the assembly line conveyor belt 3, the controller controls the two electric push rods 628 to work, and the two electric push rods 628 drive the two barrel support frames 627 to move, so that the surfaces of the two barrel support frames 627 contact the surfaces of the electrolyte barrel on the assembly line conveyor belt 3 to support the electrolyte barrel.

[0092] After the barrel support frame 627 contacts and supports the electrolyte barrel, the controller controls the conveying drive motor 610 to reverse, and at the same time, the assembly line conveyor belt 3 continues to convey the electrolyte barrel into the lifting tower 1, and the conveying drive motor 610 drives the active synchronous pulley 611 to rotate in the opposite direction, and the active synchronous pulley 611 drives the driven synchronous pulley 613 to rotate through the synchronous belt, and the driven synchronous pulley 613 drives the conveying drive shaft 612 to rotate, and the conveying drive shaft 612 drives the driving roller 614 to rotate, driving the electrolyte barrel conveyor belt 602 to rotate into the lifting tower 1, and driving the electrolyte barrel to the lifting tower 1.

After the electrolyte barrel movement blocks the laser beam sensor 620, the laser beam sensor 620 sends an electrical signal to the controller, and the controller controls the conveying drive motor 610 to stop. At the same time, the movable protective frame 622 follows the electrolyte barrel conveyor belt 602 to move in the opposite direction and reset.

Then the controller controls the lifting drive motor 503 to work, and the lifting drive motor 503 drives the driving shaft to rotate forward, and the driving shaft drives the driving gear 504 to rotate, and the driving gear 504 drives the four driven gears 506 to rotate at the same time through the four transmission gears 505, and drives the four driving screws 501 to rotate synchronously, and through the synchronous rotation of the four driving screws 501, drives the lifting bracket 4 and the electrolyte barrel conveying mechanism on the lifting bracket 4 to move upward, and lifts the electrolyte barrel.

[0094] After being lifted to the set height, the controller controls the rotation drive motor 62 to work, and the rotation drive motor 62 drives the driving worm 64 to rotate, and the driving worm 64 drives the driving worm wheel 66 to rotate, and the driving worm wheel 66 drives the rotating shaft 61 to rotate, and the rotating shaft 61 drives the supporting bottom frame 6 to rotate, and the number of rotations of the driving worm 64 is monitored by the rotary encoder 65, and the number of rotations of the driving worm 64 is fed back to the controller.
