Printed circuit board test equipment

Abstract

The invention discloses printed circuit board testing equipment, which comprises a placement device, and is characterized in that the placement device comprises a first placement plate, a first shell, a mounting rod, a clamping plate, a connecting pipe, a sliding rod, a second placement plate and an adjusting knob, and can fix a printed circuit board; the measuring device comprises a mounting base, a motor, a mounting block, a first sliding block, a first air cylinder, a second sliding block, a second air cylinder, a second shell, a feeler lever, a first spring, a third shell, a display module and a measuring module, each wiring point on the printed circuit board can be measured and displayed through the display module, and the purpose of testing the printed circuit board is achieved; and the lifting device comprises a second spring, a tray, a first movable block, a first supporting wheel, a second movable block and a second supporting wheel, and the lifting range of the lifting device is changed through airflow, so that the device adapts to printed circuit boards of different sizes.

Description

technical field [0001] The invention relates to the field of printed circuit production, in particular to a printed circuit board testing device. Background technique [0002] In the manufacturing process of printed circuit boards, it is necessary to check the electrical connection of the etched circuit on the circuit board to prevent open circuit and so on. The traditional method is to use a measuring device to measure between each wiring point through a probe, but the wiring There are many points, so a push-down test bench is generally used. There are multiple probes on the top, which can perform multi-line measurement at the same time. However, the probe structure of the traditional test bench is located above the circuit board, which makes it difficult to pick and place the circuit board. It will increase the test time when the circuit board is placed for a long time, reduce the production efficiency of the circuit board, and the position of the probe is fixed, which is ...

It will increase the test time when the circuit board is placed for a long time, reduce the production efficiency of the circuit board, and the position of the probe is fixed, which is not universal for different types of circuit boards, so that one test bench can only correspond to one type of circuit board , poor practicality
