Embodiment Construction

[0015] Below in conjunction with accompanying drawing, preferred embodiment of the present invention will be further described:

[0016] figure 1 Shown is a structural schematic diagram of the automatic component counting device of the present invention. Its composition mainly includes array detector 1, optical system 2, component tray 3, vibration mechanism 4, lighting source 5, power supply and control device 6, bracket 7, image display and data processing system 8.

[0017] Among them, the bottom plate of the component tray 3 is made of acrylic material; the vibration mechanism 4 and the lighting source 5 are set under the bottom plate; the optical system 2 is set above the tray, and the close-up photographic objective lens is selected, and the aperture diaphragm and focal length are controlled by the circuit. The tray 3; the array detector 1 is an area-array CCD camera, which can acquire the image taken by the optical system 2, and is connected with the image display and ...

Abstract

The invention discloses a method and a device for automatically counting components by using a machine vision and image processing method. Small-sized components such as chip resistors, chip capacitors and the like can be automatically counted more accurately, the counting efficiency and the counting accuracy are improved, and the labor intensity of operators is reduced.

Description

technical field [0001] The invention belongs to the technical field of screening and statistics of electronic components, and more specifically relates to a method and device for automatic counting and statistics of components by using machine vision and image processing methods. Background technique [0002] At present, in the screening of components, the usual method is that the inspector puts a large number of tiny components on the tray and counts them manually. When the number of components is particularly large, this method is easily affected by the operator's experience and psychological, physiological and other factors, and the accuracy and stability are poor. Once a verification error occurs, it needs to be counted again. [0003] When the components leave the factory, most of them are wrapped in strips, and there are small holes on the strips. Before leaving the factory, the method of photoelectric scanning is used for counting and statistics. Before the component...
