Current calibration equipment and method for charge management ICs

Abstract

The invention provides current calibration equipment and a method for charge management ICs. The current calibration method of charge management IC comprises the following steps: setting a three-dimensional coordinate axis; defining plane coordinate values on every charge management ICs on testing clamp components and height coordinate values generated during rising and downward pressing a longitudinal cylinder, wherein a logic controller drives a transversal cylinder to move according to calculated space coordinate values and a certain intervals of speed and period until the most front row of the charge management ICs are positioned under testing needle components, and the longitudinal cylinder drives the testing needle components to be pressed downwards automatically and be in contact with testing points of the most front row of the charge management ICs sufficiently to calculate current precision signals of the charge management ICs with charging protection, then, the transversal cylinder moves continuously until the next row of the charge management ICs are positioned under the testing needle components; repeating the testing steps till all of the charge management ICs are tested. According to the testing manners, the stepping type and the multichannel type are adopted, so that the degree of automation of the testing equipment is improved, and the production cost and the operation labor intensity are lowered.

Description

technical field [0001] The invention relates to a verification device and method, in particular to a charging management IC current verification device and method. Background technique [0002] At present, charging management ICs are being used more and more widely. The fields involved in charging management ICs include new energy fields such as chargers, car batteries, and computers. Its broad market prospects and considerable commercial value make it possible to develop and use equipment is of great significance. [0003] The existing traditional method for current verification of the charging management IC adopts the method of connecting the conduction product with a single-channel manual fixture. However, on the one hand, the single-channel calibration mode makes product calibration inefficient and the scalability of the calibration equipment is poor, and the number of channels cannot be flexibly configured according to the actual situation of the product quantity; Man...

AI Technical Summary

Problems solved by technology

However, on the one hand, the single-channel calibration mode makes product calibration inefficient and the scalability of the calibration equipment is poor, and the number of channels cannot be flexibly configured according to the actual situation of the product quantity; Manual adjustment, the operation process is cumbersome and error-prone, and it is not convenient for automatic management and maintenance

Therefore, the existing methods for current verification of charging management ICs have defects such as poor scalability, poor flexibility, low operating efficiency, and inconvenient intelligent management and maintenance.
