[0044] The working steps of this device are as follows: First, place the battery on the conveyor line 2. The conveyor belt 23 of the conveyor line 2 transfers the battery to the right. When the first battery moves to the right end and is blocked by the baffle 25, the blocking cylinder at the right end ejects the blocking block 21 to block the second battery. This process is repeated for all blocking cylinders. Then, the electric telescopic rod 27 ejects outward, and the push rod 20 pushes the battery into the transition groove 26, placing the battery in the transition groove 26 and waiting for the acid adding nozzle assembly 43 to move down. Next, the drive motor 434 in the acid adding nozzle assembly 43 drives the drive screw 436 to rotate. After cooperating with the drive nut 432, the mounting plate moves down. The card slot 439 provided at the bottom of the positioning block 438 of the mounting plate catches the battery, and the filling nozzle 437 is inserted into the battery, completing the matching installation of the acid adding nozzle assembly 43. At this time, the acid inlet pump in the acid quantity control assembly 3 adds acid into the upper acid tank 30. Before adding acid, the connecting hose 44 at the upper end of the acid adding cup 40 is pressed by the acid discharging rod 423 on the acid discharging opening and closing mechanism 42 to achieve the closed state. At the same time, the rotating motor 38 rotates to drive the ball screw 39 to cooperate with the screw nut 370 to drive the moving plate 35 to move, driving the functional acid quantity control rod 32 to insert into the acid adding measuring cup 31 to a certain depth, so that the acid liquid entering the acid adding measuring cup 31 meets the specified acid adding quantity. When the acid adding measuring cup 31 is filled, the excess acid liquid returns to the acid return tank 34 through the acid return pipe 33, achieving quantitative filling. Then, the vacuum pump in the vacuum pumping assembly 5 is started. The air inlet rubber hose 56 is closed by the vacuum opening and closing mechanism 53, and the vacuum hose 51 is in the open state. At the same time, the acid adding hose 41 is closed by the acid discharging opening and closing mechanism 42. In this state, the vacuum pumping assembly 5 can evacuate the battery to a vacuum state. Then, the acid discharging opening and closing mechanism 42 opens the connecting hose 44 and the acid adding hose 41. The acid liquid in the acid adding measuring cup 31 enters the acid adding cup 40 through the connecting hose 44 and then enters the battery through the acid adding hose 41 and the filling nozzle 437. At this time, the air inlet rubber hose 56 is opened by the vacuum opening and closing mechanism 53, improving the acid adding efficiency. Thus, it can be ensured that the acid adding machine realizes quantitative filling of acid liquid during the acid adding process, and it can ensure that the acid liquid is evenly distributed after entering the battery, ensuring the acid adding effect and improving the acid adding efficiency.
