Abstract

The invention discloses an automatic testing device for a super-high-quality color imaging scanner. A signal control point of a to-be-tested product is connected to a measurement channel switching unit, and a modularized digital universal meter is connected with a collection end of the measurement channel switching unit. An IO signal end of a data collection module is connected with a control end of the measurement channel switching unit, and the data collection module is in control with a stepping motor. A limiting detection unit is connected with a detection signal port of a stepping motor, and is also in feedback connection with the measurement channel switching unit. A JTAG Cable burning module is connected with the to-be-tested product through a probe. A DC power supply is connected with the measurement channel switching unit, and the data collection module, the modularized digital universal meter and the JTAG Cable burning module are respectively in communication connection with a testing computer. The device effectively improves the testing efficiency of a production line.

Description

technical field [0001] The invention relates to an automatic test device for an ultra-high-quality color imaging scanner. Background technique [0002] At present, during PCBA (circuit board) testing, operators need to manually check whether each test point on the circuit board meets the requirements one by one with a testing instrument, and manually perform JTAG programming and U disk data testing, which is extremely inconvenient. The efficiency is low, and measurement errors are prone to occur, resulting in low work efficiency and increased labor costs. Contents of the invention [0003] The purpose of the present invention is to overcome the problems of low efficiency and error-prone in existing manual testing, and provide an automatic testing device for ultra-high-quality color imaging scanners. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] The automatic test device of ultra-high-quality color imaging sc...
