Electronic component detecting system

Abstract

The invention relates to a testing system for electronic element, comprising: electronic element supply part; electronic element aligning part with no vibration transfer; glass disk for electronic element arrangement; electronic element position testing part, generating trigger signal and code; shooting part; shooting the four surfaces of electronic element; discharging part, discharging electronic element by injecting condensed air; controlling part, controlling said discharging part according to judgment about the qualification of electronic element got from trigger signal, code and shoot image. The said aligning part can align electronic element with no vibration; the judgment is made according to more than two times' shoot; the removal of inject nozzle shortens the moving route of condensed air, and so the answer speed for electronic element discharge is increased.

Description

technical field [0001] The invention relates to a detection system for electronic parts, in particular to an electronic part alignment device, an electronic part discharge device and an electronic part alignment device for automatically aligning electronic parts, judging whether they are good or bad, and discharging and classifying electronic parts according to the judgment results. Component inspection system. Background technique [0002] The electronic component inspection system is to align and photograph multilayer ceramic capacitors (multilayer ceramic capacitor) or similar electronic components, and use the captured images to judge the quality of electronic components, and then spray compressed air according to the judgment results to automatically classify them System of electronic components. [0003] Usually, electronic components such as MLCC must be judged on size, crack, gold plating amount, gold plating area, etc. before they go on the market. [0004] The pr...

Problems solved by technology

[0005] However, the problem with the existing electronic component inspection system is that the electronic components are always in a state of vibration during the process of aligning the electronic components, so it is difficult to align the electronic components in a stable state

[0006] Moreover, for the electronic component object to be inspected, the quality of the electronic component is judged based on the one-time photographed image, so there is also the problem that the selectivity of electronic component quality judgment is low

[0007] When injecting compressed air to discharge electronic components based on the quality judgment results of electronic components, it is necessary to use a nozzle, and the air movement path is long, so there is a problem of compressed air generated from the electromagnetic (solenoid) valve to the electronic component. time delay problem
