Battery voltage automatic test screening device and method thereof

Abstract

The invention relates to a battery voltage automatic test screening device and a method thereof. The device provided by the invention comprises a transfer station, a placement station and a test screening mechanism. The test screening mechanism contains a bracing frame which is arranged at one side of the transfer station. The placement station is disposed at the other side of the transfer station, corresponding to the bracing frame. A meter pen rack is arranged on the bracing frame vertical to the horizontal platform of the transfer station. Detection signals of multiple positive and negative meter pen joints are sent through input ends of a central processing unit into the central processing unit for calculation. A second push-pull mechanism is disposed on the bracing frame parallally above horizontal platform of the transfer station. A third push-pull mechanism is arranged on the bracing frame at the corresponding side of a feeding end of the transfer station. An output control end of the central processing unit controls each push-pull mechanism. The battery voltage automatic test screening device provided by the invention has a simple structure and is convenient to operate. By the adoption of the device, labor intensity of workers is reduced, voltage measuring accuracy is high, production efficiency is raised effectively, and production cost is minimized.

Description

technical field [0001] The invention relates to the field of automatic detection of open-circuit voltage of a storage battery before packaging leaves the factory, in particular to a storage battery voltage automatic detection and screening device and method thereof. Background technique [0002] Due to the popularity of electric bicycles in recent years, the efficiency of battery manufacturing is very important. Before the battery is packaged and leaves the factory, it is necessary to measure the open circuit voltage of the battery and compare the voltage of the battery that needs to be matched. If the voltage difference between the batteries does not exceed 0.03V, it means that the consistency between the battery packs is good, otherwise it is unqualified. [0003] The conventional operation is to manually measure the voltage, and artificially determine the voltage difference between the battery packs and then screen. During the measurement, the staff needs to place the ful...

Problems solved by technology

[0004] However, when the staff often measure the fourth battery, they forget the voltage of the first battery that has been measured, and finally lead to a wrong judgment, and the staff manually use the voltage detection meter. The voltage is inaccurate, which leads to the wrong judgment and screening. When the detection is completed, the battery pack needs to be removed from the workbench manually. The whole process is not only labor-intensive, but also low in efficiency and accuracy, which is a serious waste of manpower and material resources. increase production cost
