Description

Technical Field

[0001] This utility model relates to the field of lead-acid battery processing technology, and in particular to an acid quantity control device for adding acid to lead-acid batteries. Background Technology

[0002] Lead-acid batteries are devices that directly convert chemical energy into electrical energy. They are designed for rechargeability, achieving recharging through a reversible chemical reaction. They are a type of battery, belonging to the category of secondary batteries. Their working principle is as follows: during charging, external electrical energy regenerates the internal active materials, storing electrical energy as chemical energy. When discharging is needed, the chemical energy is converted back into electrical energy for output. After the power source is removed, it returns to its pre-discharge state, forming a chemical battery. Rechargeable batteries can be repeatedly charged and discharged; a battery is a battery pack composed of one or more individual cells.

[0003] The lead-acid battery acid filling machine is a piece of equipment used to inject electrolyte into lead-acid batteries during production, and it is a key step in battery manufacturing. When adding acid to lead-acid batteries, precise quantitative acid addition is required. Existing acid addition control devices are complex in structure and have poor control over the amount of acid added. Utility Model Content

[0004] The present invention aims to overcome the shortcomings of existing technologies, such as complex structure and poor acid addition control, and provides an acid addition control device for lead-acid batteries with simple structure and good acid addition control effect.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an acid quantity control device for adding acid to a lead-acid battery, comprising a frame on which the following are mounted:

[0006] An acid tank is provided, and an acid pump is connected to the outside of the acid tank.

[0007] An acid-adding measuring cup is installed at the bottom of the acid tank, and a connecting hose is connected to the bottom of the acid-adding measuring cup. The connecting hose is connected to an acid-adding assembly for adding acid to the battery.

[0010] This control device features a frame with an acid loading tank mounted on top. Several acid-adding measuring cups are connected below the tank, and an acid level control rod is installed inside each cup. An external acid pump adds acid to the tank, while simultaneously, acid from the tank flows into the measuring cups. The amount of acid added is controlled by adjusting the length of the acid level control rod extending into the tank. A connecting hose, communicating with the acid-adding assembly, is connected to the bottom of each measuring cup. An acid discharge mechanism is also mounted on the frame to control the opening and closing of the connecting hose. When adding acid to the tank, the hose is closed; when adding acid from the tank to the battery, the mechanism opens the hose, completing the acid-adding operation. This device has a simple structure and provides good control over the amount of acid added.

[0011] Preferably, the bottom of the acid loading tank is connected to an acid return pipe, which is connected to the acid return tank.

Specifically, the frame also has a rotary motor, the shaft of which is connected to the ball screw. The movable slide plate is equipped with a screw nut, and the ball screw is connected to the screw nut. The rotation of the rotary motor, in conjunction with the action of the ball screw and screw nut, drives the movable plate to move up and down, thereby moving the acid dosage control rod to adjust the acid dosage, ensuring accurate acid addition, guaranteeing acid addition precision, and improving the effectiveness and efficiency of the acid addition operation.

[0014] Preferably, the acid discharging opening and closing mechanism includes a fixed plate mounted on a frame, an acid discharging pressure plate mounted on the outer side of the fixed plate, an acid discharging cylinder connected to the fixed plate, and an acid discharging rod connected to the telescopic end of the acid discharging cylinder passing through the fixed plate and the acid discharging pressure plate.

Several acid-adding measuring cups 31 are connected below the acid tank 30. An acid level control rod 32 is installed inside each acid-adding measuring cup 31. An acid pump connected to the outside of the acid tank 30 adds acid to the tank. Simultaneously, the acid in the acid tank 30 enters the acid-adding measuring cups. The amount of acid added is controlled by adjusting the length of the acid level control rod 32 extending into the acid tank 30. A connecting hose 44, communicating with the acid-adding assembly, is connected to the bottom of each acid-adding measuring cup 31. An acid-discharging opening and closing mechanism 42 is also installed on the frame 1. This mechanism controls the opening and closing of the connecting hose 44.
