AI Technical Summary

Technical Problem

In the prior art, when using lead-acid liquid-rich batteries in high temperature environments, the sulfuric acid electrolyte inside the battery loses water, causing the positive electrode grid to lose its skeleton function, grow up and contact with the busbar to form a short circuit, causing the battery to fail prematurely. At the same time, the existing filler-adding device cannot effectively add filler into the gap between the extreme group partition bag and the busbar, resulting in overflow and waste of filler and increased cost.

Method used

A battery pole top filler device is designed, including the head and the tail. The head is a cylindrical structure with both ends open, and the discharge port is designed to be arc-shaped, so that the filler can fully cover the upper edge of the partition bag. The tail includes a feeding groove and a flow guide groove. The flow guide groove is designed as a trapezoidal structure to facilitate the flow of filler and can fill the gap between the two pole group busbars and the partition bag at the same time.

Benefits of technology

This device can effectively add filler to the gap between the pole group partition bag and the busbar to form a protective film to prevent the growth of the positive electrode grid from being short-circuited with the busbar due to high temperature loss. At the same time, the production efficiency is improved, the filling area reaches more than 2/3, and the waste of filler materials is avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of battery production, in particular to a device for adding a filler to the top of a battery pole group. Background Art

[0002] In tropical areas, the environment is hot all year round, and the ambient temperature can reach up to 43°C. When the bus is running at this temperature, the temperature of the battery compartment can reach above 65°C. There are certain safety hazards when using new energy batteries at this ambient temperature. Therefore, lead-acid flooded batteries are mainly used.

[0003] However, when the lead-acid flooded battery is operated in a high temperature environment for a long time, the water loss rate of the sulfuric acid electrolyte in the battery increases. This will further increase the density of the sulfuric acid electrolyte inside the battery. Repeated charging and discharging will cause the positive grid to lose its skeleton function and grow vertically. When the pole group in a single cell grows to a certain extent away from the plate ear, it will be short-circuited with the busbar. This will eventually cause the battery to fail prematurely.

[0004] Conventional countermeasures are to increase the thickness of the positive grid and increase its stress. However, this will increase the lead consumption cost, and the product will lose its price advantage and be unfavorable for market development. There are also methods that directly add fillers to the upper edge of the busbar and the separator bag to form a protective film to prevent the plate from growing and contacting the busbar in a high temperature environment to form a short circuit.

[0005] At present, the device for adding filler in the gap between the pole group separator bag and the bus can generally only operate on the bus in a single cell, which is inefficient. At present, the lead-acid battery is usually placed horizontally in a conventional manner, and the adding device heats the melt glue from one direction to the required glue adding position. However, the discharge port of the existing adding device is opened at the bottom, and the discharge port is vertically set downward, and it is impossible to extend into the gap between the pole group separator bag and the reflux bar to realize fixed-point feeding, resulting in the inability to completely add filler in the gap between the pole group separator bag and the bus, and the filler overflows and wastes, which increases the cost. Summary of the invention

[0006] The purpose of the utility model is to solve the above-mentioned deficiencies of the prior art, thereby providing a device for adding a filler to the top of a battery pole group to improve production efficiency.

[0007] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a device for adding filler to the top of a battery pole group, comprising a head for receiving materials and a tail for guiding flow;

[0008] The head is a cylindrical structure with openings at both ends, the opening at the upper end of the head is a feed inlet, and the opening at the lower end is a discharge outlet;

[0009] The tail portion includes a material receiving trough and two side-by-side guide troughs located at the lower end of the material receiving trough;

[0010] The receiving groove is an open groove with an open lower end surrounded by a front side wall, a rear side wall, a left side wall, a right side wall and an upper side wall, the lower open end of the open groove is a discharge port for the filler, and the upper side wall is provided with an opening connected to the head discharge port;

[0011] The two guide grooves are separated and formed with a gap for making way for the battery slot partition wall. The lower ends of the two guide grooves are bent to one side and the rear ends are provided with a filler adding port.

[0012] A stop notch is provided on one side of the head for observing the insertion depth of the external filler access tube, and the stop notch is arranged horizontally.

[0013] The head side wall has a through slot extending in the axial direction, the upper end of the through slot is flush with the feed port, the lower end is connected with the stop notch, and symmetrical ears are arranged at both ends of the through slot, and symmetrical clearance holes are opened on the ears.

[0014] After the external filler access tube is inserted into place, the external filler access tube is fastened to the head by bolts and nuts installed at the two ear clearance holes.

[0015] The horizontal cross-sectional area of ​​the upper end of the guide groove is larger than the cross-sectional area of ​​the lower end.

[0016] The front side surface of the guide groove is a trapezoidal structure that is larger at the top and smaller at the bottom, and the left and right side surfaces of the guide groove are trapezoidal structures that are narrower at the top and wider at the bottom.

[0017] The width of the guide groove is consistent with the width of the busbar in a single cell of the battery slot.

[0018] The utility model has a large upper space and a small lower space at the tail, which is convenient for the filling agent to flow; the filling agent output port is designed in an arc-shaped mouth shape, which is convenient for the filling agent to fully cover the upper edge of the partition bag.

[0019] The utility model can add filler to the upper edge of the separator bag to form a layer of protection, thereby preventing the positive plate grid from growing due to high temperature water loss and causing the busbar to be short-circuited.

[0020] The utility model can simultaneously fill the gap between two pole group bus bars and the partition bag at a time, and the filling area is more than 2 / 3. The production cycle will not be reduced, and no waste of filler materials will be caused.

[0021] The utility model is easy to install and disassemble, and is made of aluminum silicate, which has good heat insulation effect. When the machine stops abnormally, the filler will not be blocked. BRIEF DESCRIPTION OF THE DRAWINGS
