DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-8 The utility model provides a technical solution: an acid injection device for a lead-acid battery, comprising a workbench 1 and a conveying unit 2 arranged under the workbench 1 for transporting a lead-acid battery body 5, and further comprising:

[0029] A limiting unit 3 is provided on the conveying unit 2 and is used to limit the position of the lead-acid battery body 5;

[0030] The acid injection unit 4 is arranged on the workbench 1 and is used for injecting acid into the lead-acid battery body 5 transported by the conveying unit 2 .

[0031] It should be noted that, during operation, multiple lead-acid battery bodies 5 are placed one by one on the conveying unit 2, and the number and position of the placement can be controlled according to the number and position of the acid injection unit 4, and then the conveying unit 2 transports the lead-acid battery body 5 to the upper and lower parts of the workbench 1. When the conveying unit 2 is conveying, the limiting unit 3 can guide the lead-acid battery body 5 on the conveying unit 2, so that the acid filling port of the lead-acid battery body 5 is aligned with the acid filling port of the acid injection unit 4, thereby improving the acid injection efficiency of the lead-acid battery body 5. When the size of the lead-acid battery body 5 changes, the position of the acid filling port of the lead-acid battery body 5 can be adjusted by the limiting unit 3, so that the acid filling port of the lead-acid battery body 5 is located directly below the acid filling port of the acid injection unit 4, so that the entire acid injection device can be suitable for processing lead-acid battery bodies 5 of different sizes, making the entire device more practical.

[0032] In one embodiment, the limiting unit 3 includes an L-shaped fixed plate 31 symmetrically fixed on the conveying unit 2, a limiting plate 32 adjustably arranged between the two fixed plates 31, a screw 33 rotatably arranged on the side of the fixed plate 31 close to the limiting plate 32, and a turntable 34 arranged on the side of the screw 33 away from the limiting plate 32, and the screw 33 is threadedly connected to the fixed plate 31.

[0033] In this design, the turntable 34 is rotated, and the screw 33 drives the limiting plate 32 to move above the conveying unit 2. By adjusting the distance between the two limiting plates 32, the limiting plate 32 adjusts the position of the lead-acid battery body 5 on the conveying unit 2, and the acid filling port of the lead-acid battery body 5 is adjusted to a horizontal position just below the acid filling port of the acid injection unit 4. When the acid filling port of the lead-acid battery body 5 is aligned with the acid filling port of the acid injection unit 4, the acid injection port of the acid injection unit 4 is moved to the acid filling port of the lead-acid battery body 5, and the lead-acid battery body 5 is acid-filled. After the acid filling work is completed, the conveying unit 2 conveys the lead-acid battery body 5 to the next station, and moves the next group of lead-acid battery bodies 5 that need acid injection to the bottom of the acid injection unit 4, so as to realize continuous processing of the lead-acid battery body 5 and improve the acid injection efficiency of the lead-acid battery body 5.

[0034] In one embodiment, the bottom of the limiting plate 32 is configured to be L-shaped and fits tightly with the bottom of the fixing plate 31 .

[0035] With this design, the bottom of the limiting plate 32 fits tightly with the fixing plate 31 , which can limit the movement of the limiting plate 32 , so that the limiting plate 32 moves horizontally above the conveying unit 2 , thereby improving the guiding effect of the limiting plate 32 on the lead-acid battery body 5 .

[0036] In one embodiment, a guide rod 35 is disposed on one side of the limiting plate 32 close to the fixing plate 31 , and the guide rod 35 penetrates the fixing plate 31 .

[0037] With this design, the guide rod 35 can guide the limiting plate 32 to prevent the lead-acid battery body 5 from squeezing the limiting plate 32 and causing the limiting plate 32 to tilt, thereby affecting the limiting effect on the lead-acid battery body 5. When the lead-acid battery body 5 moves to just below the acid injection unit 4, the acid injection port of the lead-acid battery body 5 cannot be aligned with the acid injection port of the acid injection unit 4, causing the hazard of leakage of sulfuric acid solution during acid addition.

[0038] In one embodiment, the acid injection unit 4 includes a liquid storage tank 41 fixed on one side of the workbench 1, a liquid outlet pipe 42 arranged at the liquid outlet end of the liquid storage tank 41, and a liquid injection device 43 arranged on the workbench 1 and connected to the liquid outlet pipe 42 for injecting acid into the lead-acid battery body 5, and the liquid injection device 43 is located between the two limiting plates 32.

[0039] In this design, the liquid storage tank 41 is provided with a liquid inlet 411 for replenishing the sulfuric acid solution, and the liquid outlet pipe 42 is connected with a delivery pump, which can deliver the sulfuric acid solution in the liquid storage tank 41 to the liquid injection device 43 for liquid injection.

[0040] In one embodiment, the injection device 43 includes a fixed frame 431 fixed on the workbench 1, a hydraulic cylinder 432 fixed on the fixed frame 431, a connecting frame 433 arranged at the power output end of the hydraulic cylinder 432, and an injection nozzle 434 arranged on the connecting frame 433, and the injection nozzle 434 is connected to the liquid outlet pipe 42.

[0041] In this design, when the lead-acid battery body 5 moves to the acid injection station, the hydraulic cylinder 432 is started, driving the connecting frame 433 to move downward, so that the liquid injection nozzle 434 is inserted into the acid injection port of the lead-acid battery body 5, and then the delivery pump is turned on to add sulfuric acid solution from the liquid storage tank 41 into the lead-acid battery body 5, thereby completing the acid injection work of the lead-acid battery body 5.

[0042] In one embodiment, the conveying unit 2 includes a mounting frame 21 arranged below the workbench 1, a motor 22 arranged on one side of the mounting frame 21, a transmission roller 23 arranged at intervals on the mounting frame 21 and connected to the power output end of the motor 22, and a transmission belt 24 sleeved on the transmission roller 23. The mounting frame 21 is provided with a support member 25 for supporting the lead-acid battery body 5 at the upper end of the transmission belt 24.

[0043] In this design, the motor 22 is started, driving the transmission roller 23 to rotate, so that the transmission roller 23 drives the transmission belt 24 to move inside the mounting frame 21, and the transmission belt 24 transports the lead-acid battery body 5 placed above it, and transports the lead-acid battery body 5 to the bottom of the workbench 1 to align with the injection nozzle 434, the motor 22 stops, and the lead-acid battery body 5 is injected with acid. After the acid injection work is completed, the motor 22 is started to transport the lead-acid battery body 5 that has been injected with acid to the next process, and another group of lead-acid battery bodies 5 that need to be injected with acid on the transmission belt 24 are moved to the bottom of the injection nozzle 434.

[0044] In one embodiment, the support member 25 includes a fixed block 251 symmetrically fixed on the mounting frame 21, a vertical plate 252 fixed between the two fixed blocks 251, and a horizontal plate 253 fixed at the upper end of the vertical plate 252. The fixed blocks 251 are arranged at intervals below the transmission belt 24, and the top of the horizontal plate 253 abuts against the transmission belt 24.

[0045] With this design, the cross plate 253 is placed horizontally below the transmission belt 24, which can support the lead-acid battery body 5 on the transmission belt 24, so that the lead-acid battery body 5 can move horizontally on the transmission belt 24, avoiding the lead-acid battery body 5 from bending the transmission belt 24, so that when the lead-acid battery body 5 moves to the bottom of the injection nozzle 434, the acid filling port of the lead-acid battery body 5 cannot be aligned with the injection nozzle 434.
