Inspection and selection device for chip electronic components

Abstract

[Problem] To provide a chip electronic component inspection and sorting device whereby substandard chip electronic components can be prevented from being admitted to a chip electronic component accommodating container and whereby a chip electronic component can easily be extracted from a chip electronic component-accommodating container. [Solution] In an inspection and sorting device for chip electronic components, chip electronic components that are accommodated in a large number of through-holes (23) that are provided in a chip electronic component holding plate (24) are inspected and sorted in accordance with their electrical properties and are accommodated in at least two chip electronic component accommodating containers (34) whose upper faces are open. In this device, in a chip electronic component discharge passage support structure (39a) that is connected with discharge passages (37) for chip electronic components that are discharged from the through-holes (23) of the aforementioned holding plate (24), pressurised gas escape passages (41) are provided whereby at least some of the pressurised gas that is delivered into a container (34) through a discharge passage (37) can escape. Also, the containers (34) are supported by raising / lowering means (42) whereby the gap between the open faces (33) of these containers (34) and the underside surface (43a) of the support structure (39a) can be adjusted.

Description

technical field [0001] The present invention relates to a device for inspecting and selecting a large number of chip electronic components at high speed. Background technique [0002] As the production volume of electronic products typified by mobile phones, liquid crystal televisions, and game machines increases, the production volume of chip electronic components incorporated in such electronic products is remarkably increasing. As chip electronic components, chip capacitors (also referred to as chip capacitors), chip resistors (including varistors), and chip inductors are widely known. [0003] Chip electronic components such as chip capacitors have extremely small dimensions (for example, about 0.3 mm in width and about 0.6 mm in length), and a large number of chip capacitors of tens of thousands to hundreds of thousands are produced in one production . [0004] In order to reduce the defect rate of electrical products incorporating chip electronic components due to de...

Problems solved by technology

When the opening of the upper surface of each sub-box is blocked with a shelf board, since it becomes impossible to discharge the chip electronic components and the air sent to each sub-box through the above-mentioned discharge mechanism, it becomes difficult to send the chip electronic components to each sub-box. case, and because it becomes impossible to easily remove the case tray on which the case is placed from the device
