Problems solved by technology

[0003] At present, the general voltage internal resistance detection and matching in China are realized through manual operation. The actual voltage internal resistance value of each battery cell is detected manually through a voltage internal resistance tester. Manual operation has many uncertainties, including missed testing, false In many cases, such as testing, some defective products cannot be selected accurately and in time, which will lead to the flow of defective products to customers, resulting in unpredictable consequences

Abstract

The invention relates to a method for automatically detecting voltage and internal resistance of a battery and spraying a code, which comprises the following steps of: 1, starting a drawstring motor to drive a conveyor belt until infrared detection indicates that the battery is in place; controlling to open an air pump solenoid valve to clamp the battery until the measurement is finished or the specified time is up, and closing the air pump solenoid valve, returning to a testing clamping mechanism, and loosening the battery; receiving the measured data of a voltage and resistance tester and returning to the first step; and outputting spray print contents according to the measured data of each battery and controlling a code spraying machine to perform spray print on batteries which are transmitted to the nozzle one by one. The automatic detection and code spraying method is full automatic, the working efficiency and accuracy are improved, and detection missing is avoided.

Description

technical field [0001] The invention relates to battery production, in particular to a method for automatic detection and coding of battery voltage and internal resistance. Background technique [0002] Before the lithium-ion battery is shipped, the electrical properties of the lithium-ion battery must first be tested. The electrical performance indicators of the battery mainly refer to the voltage, internal resistance, and capacity of the battery. For the battery pack, it is required that the capacity, voltage, and internal resistance data of the cells of the same set of batteries are not much different, because for the same set of batteries , its performance is affected by each of these cells. [0003] At present, the general voltage internal resistance detection and matching in China are realized by manual operation, and the actual voltage internal resistance value of each battery cell is detected manually through a voltage internal resistance tester. Manual operation ha...
