Embodiment 1

[0028] Such as figure 1 As shown, an AOI visual detection device includes a frame 9, a detection device, a sensing device and a central processing unit (not shown in the figure). The detection device is fixedly connected to the frame 9 and fixedly arranged above the assembly line 1. The detection device includes a frame 2, an imaging device and a light source. The area of ​​the assembly line 1 corresponding to the frame 2 above it forms a detection area; the imaging device corresponds to the detection area It is arranged on the frame 2 and is connected with the central processor by electrical signals, and is used for imaging the detection area and transmitting the imaging data to the central processor. The induction device includes an RFID reader-writer 6 and a through-beam photoelectric sensor 10. The RFID reader-writer 6 is fixedly arranged at the upstream end of the assembly line 1, and is connected to the central processing unit with electrical signals for reading the note...

Embodiment 2

[0035]The rest are the same as in Embodiment 1, the difference is that the sensing device includes a barcode scanning gun and a diffuse photoelectric sensor, and the barcode scanning gun is fixedly arranged at the upstream end of the assembly line for scanning the barcode on the notebook computer under test, and the barcode scanning gun and the photoelectric sensor are respectively connected with the central processing unit by electrical signals.

Embodiment 3

[0037] All the other are identical with embodiment 1, and difference is, as figure 2 As shown, the frame 9 is movably arranged on one side of the assembly line, and the detection device is fixedly connected to the frame 9 and arranged above the assembly line 1 .

Abstract

An AOI visual detection device comprises a rack, a detector, a sensing device and a central processing unit. The detector is arranged above an assembly line and comprises imaging devices and a light source, the imaging devices are used for imaging keyboards of notebook computers in a detection region of the assembly line and outputting imaging data, and the light source is used for brightness supplement. The sensing device is arranged on the assembly line and the rack and used for sensing the detected computers and outputting sensing signals. The central processing unit is in signal connection with the imaging devices and the sensing device and is used for receiving the sensing signals and conducting corresponding data processing and control output. According to the AOI visual detection device, keyboard identifiers and volume labels of the notebook computers can be immediately and automatically detected online, the detection efficiency is improved, the labor cost is saved, and mistaken detection and missing detection caused by human factors are avoided.

Description

technical field [0001] The invention relates to a detection device, in particular to an AOI visual detection device for online detection of computer keyboards. Background technique [0002] With the popularity of computers, computers have entered almost all industries and played a pivotal role. It has become an indispensable tool for the normal operation of today's society. In order to meet the needs of various groups of people, computer styles and models emerge in an endless stream, and each computer has its own individual shape and specification design. [0003] When the manufacturer produces computer keyboards, because the keyboard position, logo and volume label on each type of computer keyboard are different, it is necessary to compare and test the computer keyboard with a standard template during online production. In the existing assembly line inspection, inspectors select transparent standard templates according to the production model to compare the products after ...
