Manufacturing method of maintenance-free motorcycle battery lead terminal structure

Abstract

The invention discloses a manufacturing method of a maintenance-free motorcycle battery lead terminal structure, which comprises the following steps of: firstly, fixing a nut (7) in a lead terminal die cavity and directly pouring lead liquid molten at a high temperature into the lead terminal die cavity for carrying out casting molding to form a lead terminal (8); then fixing the lead terminal in a battery cover die cavity and carrying out high-temperature injection molding to form a battery cover (9); secondly, arranging and cast-welding a negative plate (2), a separator (3) and a positive plate (4) at intervals into a pole group and welding a bus bar (5) on the pole group; cast-welding on the bus bar (5) to directly form a pole (6); thirdly, carrying out heat seal on a battery case (1) and a battery cover (9) so that the pole (6) is matched with the lead terminal (8), welding the pole (6) with the lead terminal (8) together in an acetylene welding manner; and finally, pouring an electrolyte to form a battery. According to the manufacturing method, the production operating process is reduced, the production fraction defective is reduced and the appearance quality of the battery is improved, but also the problem of wiring mode of the motorcycle battery is solved, the motorcycle battery is convenient to operate and is easy to install and the problem of acid creeping at the lead terminal of the battery is avoided.

Description

[0001] technical field [0002] The invention relates to a method for manufacturing a motorcycle battery, in particular to a method for manufacturing a lead terminal structure of a maintenance-free motorcycle battery. Background technique [0003] Lead-acid batteries are widely used because of their low price, reliable quality, large capacity range, easy maintenance, and long service life. In recent years, with the development of the world's energy economy and the improvement of people's living standards, motorcycles, as leisure tools, have been widely promoted and used in rural areas of China, and the demand for motorcycle batteries is also gradually increasing. [0004] In the production process of the lead-acid battery, the battery terminal is an important part of the lead-acid battery. As the terminal connected to the electric facility, it is required to be able to withstand a certain large current charge and discharge, to ensure the maximum power of the battery, no heat,...

Problems solved by technology

At present, the motorcycle battery terminals produced by most manufacturers have circular screw holes on the front and top surfaces, and a square hole structure on the side. The only way to connect them is to place the nuts in the square holes and then tighten the wiring screws. It is more difficult and cumbersome at the same time. The torque test of the battery terminals does not meet the required data. Due to the long-term bumpy use of the battery on the motorcycle, the terminal connection is easy to loosen and the battery terminal sparks. In the increasingly competitive market lack of competitiveness
