Electronic part loading state detection device

Abstract

The invention relates to an electronic part loading state detection device comprising at least one light irradiation device, at least one camera, and an analyzer. The light irradiation device is used to irradiate light on a plurality of electronic parts disposed on loading trays on detection positions. The at least one camera is used to shoot the plurality of electronic parts used to irradiate light by using the light irradiation device. The analyzer is used to analyze the loading states of the electronic parts by the shape of the light in the images acquired by the camera. By viewing from a front side, an included angle between a first line used for connecting a reflection point and the camera and a second line used for connecting the reflection and the light irradiation device is greater than 0degree, and is smaller than 180degrees. The above mention reflection point can be one of the connection positions between the light irradiated by the light irradiation device on the electronic parts and the plurality of electronic parts. The changing shapes of the irradiated light are used to detect the loading states of the electronic parts, and a processing speed is fast, and the loading states of the electronic parts are determined accurately.

Description

technical field [0001] The present invention relates to an electronic component loading state detection device for detecting whether electronic components are properly loaded on a loading tray on which electronic components can be loaded. Background technique [0002] Electronic components such as solid-state drives (SSD, Solid-state Drive) or memory sticks need to go through label attachment operations, casing operations, and electrical characteristic testing operations before leaving the factory. [0003] In order to perform the above work, electronic components often need to be transported in a state loaded on a loading tray. Of course, usually multiple electronic components are loaded together on the loading tray. [0004] However, if the loading state of the electronic components is not good, the sampling robot will also be poorly held, so there may be problems in the label attaching work or the encapsulation work, and the electrical contact with the tester may be bad,...

Problems solved by technology

[0008] In addition, Korean Laid-Open Patent No. 10-2011-0100403 (hereinafter referred to as "Prior Art 2") and the like discloses the technology of using a camera for detection, but in the case of the prior art 2, the surface captured by the camera also needs to be relatively wide

Furthermore, according to the technology disclosed in prior art 2, when the multiple lines constituting the structure of the loading tray are complex, it may be difficult to grasp the loading state of the loading tray in the image captured by the camera, and even if it is grasped, it is necessary to confirm the electronic state. It takes a long time to analyze parts such as Line

In addition, production costs are also increased due to the use of expensive cameras and high-performance analyzers to capture clear images

[0009] Therefore, it is difficult to apply the prior art 1 and the prior art 2 when the electronic components are placed on the loading tray in a vertical state.
