Description

Technical Field

[0001] The utility model belongs to the technical field of electrolyte filling devices, and particularly relates to a battery electrolyte filling device. Background Art

[0002] Batteries are widely used in various production and living products. During the production process of batteries, it is necessary to fill the electrolyte into the closed housing. Currently, manual filling is usually adopted. The common filling standard is that the liquid level can be seen from the filling port of the battery. This filling method often has the problem of electrolyte overflow, which not only easily causes waste of electrolyte, but also pollutes the environment and harms the human body. Content of the Utility Model

[0003] To solve the deficiencies of the prior art, the utility model provides a battery electrolyte filling device, which can timely control the opening and closing of the filling pipe and effectively prevent electrolyte overflow.

[0004] To achieve the purpose of the utility model, the following scheme is proposed:

[0005] A battery electrolyte filling device includes a filling pipe and a guide rod.

[0006] The lower end of the filling pipe is an oil outlet. A liquid inlet pipe is communicated with the side wall of the upper end of the filling pipe for introducing electrolyte into the filling pipe. A pull rod is coaxially arranged inside the filling pipe, and a valve is arranged at its lower end. The valve is located below the filling pipe. A lifting device is arranged at the top of the filling pipe for controlling the movement of the pull rod along the axis.

[0007] The guide rod is arranged parallel to one side of the filling pipe and is movably arranged along the axis. A floating ball is arranged at the lower end of the guide rod, and the height of the floating ball is lower than the oil outlet of the filling pipe. A sensor is arranged outside the filling pipe corresponding to the upper part of the guide rod. When the sensor senses the guide rod, the lifting device drives the pull rod to move upward, so that the valve closes the oil outlet of the filling pipe.

[0008] The beneficial effect of the utility model is that the floating ball arranged at the lower end of the guide rod senses the filling position of the electrolyte in time, and the sensor detects the position signal of the guide rod. The lifting device controls the valve to close the filling pipe according to the in-place signal, so as to timely close the liquid outlet hole of the filling pipe and avoid electrolyte overflow.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will describe the implementation manners of the present utility model in detail with reference to the accompanying drawings. However, the embodiments described herein are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0016] As Figures 1 to 4 shown, a battery electrolyte filling device includes: a filling tube 1 and a guide rod 4.

[0017] The lower end of the filling tube 1 is an oil outlet. A liquid inlet tube 11 is communicatively connected to the side wall of the upper end of the filling tube 1 for introducing electrolyte into the interior of the filling tube 1. A pull rod 2 is coaxially arranged inside the filling tube 1, and a valve 21 is provided at its lower end. The valve 21 is located below the filling tube 1 and is used to control the opening and closing of the oil outlet of the filling tube 1. A lifting device 3 is provided at the top of the filling tube 1, and its movable end is connected to the pull rod 2 for controlling the movement of the pull rod 2 along the axis.

[0018] The guide rod 4 is arranged parallel to one side of the filling tube 1 and is movably arranged along the axis. Specifically, a support plate can be provided on the side wall of the filling tube 1, and the guide rod 4 is passed through the support plate. A floating ball 41 is provided at the lower end of the guide rod 4, and the height of the floating ball 41 is lower than the oil outlet of the filling tube 1. An inductor 5 is provided outside the filling tube 1 corresponding to the upper part of the guide rod 4. The inductor 5 is a proximity switch or a photoelectric switch. When the inductor 5 senses the guide rod 4, the lifting device 3 drives the pull rod 2 to move upward, so that the valve 21 closes the oil outlet of the filling tube 1.

[0019] Working principle: Insert the filling pipe 1 and the guide rod 4 together into the filling hole of the battery to a predetermined depth, which is based on the sensor 5 sensing the guide rod 4 after the electrolyte is filled to the predetermined position; then send the electrolyte into the filling pipe 1 through the liquid inlet pipe 11, and then the electrolyte can automatically drain from the liquid outlet; when the liquid level of the electrolyte rises to the height of the floating ball 41 and continues to be filled, the floating ball will rise under the buoyancy of the electrolyte, so that the guide rod 4 moves upward. When the upper end of the guide rod 4 moves into the sensing range of the sensor 5, the sensor 5 will sense the in-place signal of the guide rod 4. At this time, it means that the electrolyte has been filled to the predetermined position, and the in-place signal sensed by the sensor 5 is used as the start signal of the lifting device 3. At this time, the lifting device 3 starts, and then drives the valve 21 to close the liquid outlet of the filling pipe 1 through the pull rod 2, so as to prevent the electrolyte from overflowing due to excessive filling; because the valve 21 is arranged at the bottom of the filling pipe 1, the liquid outlet can be quickly closed, so that the electrolyte inside the filling pipe 1 still remains inside the filling pipe 1 to avoid the liquid inside the filling pipe 1 from continuing to drain into the battery and further prevent the electrolyte from overflowing.

[0020] Preferably, as Figures 1 to 3 shown, a regulating rod 6 is arranged in parallel on the outer side of the filling pipe 1, and it passes through a bracket arranged on the outer side of the filling pipe 1. When the filling pipe 1 is inserted into the battery to a predetermined depth, the lower end of the regulating rod 6 contacts the top surface of the battery. The regulating rod 6 is of a screw structure, and by rotating the regulating rod 6, the height difference between the lower end of the regulating rod 6 and the lower end of the filling pipe 1 can be changed to facilitate adaptation to different models of batteries.

[0021] Preferably, as Figure 2 、 Figure 3 shown, the lower ends of the filling pipe 1 and the guide rod 4 both pass through the same guiding block 7, and its outer contour matches the filling hole of the battery. When filling the electrolyte, the guiding block 7 is inserted into the filling hole of the battery to prevent the electrolyte from splashing. At the same time, it is convenient for the filling pipe 1 and the guide rod 4 to be inserted into the filling hole at the same time, and the guiding block 7 is used to protect the lower ends of the filling pipe 1 and the guide rod 4 to prevent the lower ends of the two from being knocked; because the filling hole is usually a round hole structure, the guiding block 7 is also set to a corresponding cylindrical structure.

[0022] Further preferably, as Figure 2 、 Figure 3As shown, a conduit 8 is sleeved outside the guide rod 4, and there is a predetermined interval between the outer wall of the guide rod 4 and the inner wall of the conduit 8. Specifically, one or more layers of mesh plates can be arranged inside the conduit 8, and the guide rod 4 passes through the mesh plates, so as to achieve the purpose of having a predetermined interval between the outer wall of the guide rod 4 and the inner wall of the conduit 8. The conduit 8 is located below the inductor 5, and the conduit 8 passes through the guide block 7. When the filling pipe 1 fills the electrolyte into the battery, the air inside the battery can be discharged out through the conduit 8 to prevent the electrolyte filling from being blocked due to the increase in the internal pressure of the battery. The guide block 7 is made of rubber.

[0023] Preferably, as Figure 1 , Figure 3 shown, the top surface of the valve 21 is a conical structure, and the inner wall of the lower end of the filling pipe 1 has a conical hole matching the conical structure, so as to improve the sealing effect of the valve 21 on the filling pipe 1.

[0024] The above are only the preferred embodiments of the present invention, and do not represent the only or limit the present invention. Those skilled in the art should understand that various changes or equivalent replacements made to the present invention without departing from the scope of the present invention all fall within the scope of protection of the present invention.
