Description

Technical Field

[0001] The invention relates to the technical field of lead-acid battery acid-adding tools, in particular to an acid-adding device for a lead-acid battery. Background Art

[0002] Sulfuric acid, the electrolyte of lead-acid batteries, is an important component of the battery and plays a decisive role in the performance of lead-acid batteries. Different battery types have different ways of adding acid. Currently, most manufacturers mainly use free acid and vacuum acid. These two acid adding methods are completely impractical for pure lead flat batteries and wound batteries, and there are the following problems:

[0003] During the use of lead-acid batteries, acid addition operations need to be performed. Manual acid addition has safety hazards, and an acid addition device is required for acid addition. The current automatic acid addition device for lead-acid batteries has a fixed position of the acid addition tube, which will cause the acid addition tube to be unable to adapt to the lead-acid batteries with different acid addition port spacings for mobile adjustment operations, and can only process batteries of the same specification. If acid is added to other batteries, a corresponding pre-set acid addition machine is required, so the acid addition efficiency is very low, affecting the scope of application of the equipment; and the existing acid addition equipment also has the problem that when the acid addition head is about to fill the lead-acid battery with acid, acid splashing and leakage are prone to occur, affecting the protective effect of the lead-acid battery shell; at the same time, during the process of adding acid, since there is no pre-exhaust operation inside the lead-acid battery, as the liquid level inside the lead-acid battery rises, the internal air pressure will also increase, and then when the acid addition tube is removed from the acid addition port, the acid addition tube is prone to dripping, which reduces the protective performance of the lead-acid battery when adding acid; therefore, the above problems need to be solved.

[0043] Working principle: In this embodiment, the present invention also proposes a method for using the acid adding device of a lead-acid battery, comprising the following steps:

[0044] Step 1: First, the pumping machine 11, the micro motor 17, the servo motor, the electronic valve, the electric exhaust valve and the vacuum pump 32 are electrically connected to the external control device through wires, and then the supply cylinder 12 is filled with the dilute sulfuric acid to be filled, and then the lead-acid battery to be filled with dilute sulfuric acid is placed on the support plate 9, and then the micro motor 17 is started to drive the lead screw 16 to reverse, and when the lead screw 16 reverses, the longitudinal displacement seat can drive the support plate 9 to move backward;

[0045] Step 2: As the support plate 9 moves, the lead-acid battery to be filled with acid is easily moved to the bottom of the lifting frame 4, and the driving component cooperates with the support plate 9 to vertically align the injection port on the lead-acid battery with the injection cone 23 on the lifting frame 4. After the acid injection port of the lead-acid battery is aligned with the injection cone 23, the driving component stops adjusting the longitudinal movement of the support plate 9;

[0046] Step three, then according to the spacing of the acid filling ports on the lead-acid battery, the corresponding spacing of the sliding plate 13 installed on the lifting frame 4 is adjusted, so that the injection cone 23 installed on the sliding plate 13 can be aligned with the acid filling port on the lead-acid battery, and after adjusting the spacing of the sliding plate 13, the positioning screw 24 is driven to descend by turning the knob, and the descending of the positioning screw 24 can drive the locking block 25 to be pressed in the damping groove, so that the positioning screw 24 and the locking block 25 can limit and lock the adjusted sliding plate 13;

[0047] Step 4, then start the adjustment component to drive the guide tube 7 to descend, and when the guide tube 7 descends, the lifting frame 4 can be driven to descend, and the injection mechanism is driven to descend by the descending lifting frame 4, so that the injection cone 23 in the injection mechanism is lowered and inserted into the acid filling port of the lead-acid battery. When the injection cone 23 is inserted into the acid filling port, the sealing rubber cylinder 22 sleeved at the bottom of the injection tube 21 will be pressed against the side of the acid filling port of the lead-acid battery, thereby preventing the injection cone 23 from splashing and dripping during the acid filling process; and the acid filling port of the lead-acid battery is sealed;

[0048] Step 5, then start the vacuum pump 32 and the gas collecting pipe 31 to perform a vacuum operation on the inside of the lead-acid battery before acid addition. After the suction force is generated inside the gas collecting pipe 31, the electric exhaust valve on the upper air outlet pipe of the injection cone 23 inserted at the acid addition port of the lead-acid battery is opened accordingly. Then, the shunt pipe 27, the partition plate 28 and the automatic sealing plate 29 can be used to facilitate the exhaust operation of the front end battery through the injection cone 23 inserted into the acid addition port, so as to facilitate the vacuum operation before acid addition to the lead-acid battery. Through the setting of the automatic sealing plate 29, it is convenient to make the bottom opening of the liquid passage cavity open only when liquid passes through the interior. At this time, when the lead-acid battery is evacuated, the liquid passage cavity on one side of the partition plate 28 can be automatically closed to avoid the vacuum inside the connecting hose 15.

[0049] Step 6, after the lead-acid battery is vacuumed, the electric exhaust valve on the air outlet pipe is closed, and then the electronic valve on the connecting hose 15 corresponding to the acid injection port is opened, and then the pumping machine 11 is started to transport the dilute sulfuric acid in the supply cylinder 12 into the connecting hose 15, and the dilute sulfuric acid entering the connecting hose 15 will flow into the shunt pipe 27, and then the dilute sulfuric acid entering the shunt pipe 27 will enter the injection cone 23 through the liquid cavity. At this time, the automatic sealing plate 29 on one side of the bottom of the partition plate 28 will automatically flip downward under the action of liquid gravity, so that the bottom opening of the liquid cavity is opened; and then the dilute sulfuric acid is injected into the lead-acid battery through the injection cone 23;

[0050] Step 7, after completing the acid addition operation for the lead-acid battery, the electronic valve on the connecting hose 15 is synchronously closed, and then the start-up adjustment component drives the guide tube 7 to rise, and the lifting frame 4 is driven to rise by the lifting of the guide tube 7, and then the injection cone 23 is lifted out of the acid filling port of the lead-acid battery; because the lead-acid battery is in a vacuum state before the acid is added, the connecting hose 15 can be located inside the front end tube body of the electronic valve, and the shunt pipe 27, the injection pipe 21 and the injection cone 23 will not have residual acid; avoid the injection cone 23 dripping acid after it is lifted out of the acid filling port; finally, after the lifting frame 4 is lifted, the driving component is started again to drive the support plate 9 to move forward on the top of the processing table 1, and then the lead-acid battery filled with dilute sulfuric acid can be removed from the support plate 9; by moving the support plate 9 forward, the operator can avoid the accidental contact between the hand and the injection cone 23 when taking and placing the lead-acid battery, thereby improving the protection effect of the lead-acid battery when adding acid.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
