Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.
A kind of thin film switch AOI detecting device as shown in Figure 1, comprise signal collecting device, AOI function detection equipment, AOI appearance detecting device, detection record equipment and detection signal output device.The AOI function detection equipment is for detection of the comprehensive function of thin film switch to be measured, and the AOI appearance detecting device is for detection of the outward appearance of thin film switch to be measured, and detection record equipment is for recording testing result, and the detection signal output device is for showing testing result.The input end of AOI function detection equipment, AOI appearance detecting device is connected with signal collecting device respectively, and the output terminal of AOI function detection equipment, AOI appearance detecting device is connected with the detection signal output device with the detection record equipment connection respectively.Like this, the information of the thin film switch to be measured obtained from signal collecting device passes to AOI function detection equipment and AOI appearance detecting device, detects and obtains testing result, then testing result is passed to detection signal output device and detection record equipment.Detection record equipment is recorded testing result, is convenient to search.
As a kind of preferred version, the detection signal output device comprises NG output device and OK output device.The NG output device comprises alarm and red light, and the OK output device comprises bar code output device and green light.Preferably, alarm is hummer.
When testing result was defective, the NG output device sent defective prompting, and hummer sends chimes of doom, and red LED lamp lights.When testing result was qualified, the OK output device sent qualified prompting, and bar code output device output bar code is attached on qualified thin film switch, and green LED lamp lights.
As a kind of preferred version, signal collecting device adopts camera, is convenient to accurately read the information of thin film switch to be measured.
The AOI detection method of a kind of thin film switch based on thin film switch AOI detecting device of the present invention as shown in Figure 2, comprise the steps:
1) with signal collecting device, read the information of thin film switch to be measured;
2) information is passed to AOI function detection equipment and AOI appearance detecting device, carry out AOI Function detection and AOI outward appearance and detect, obtain respectively Function detection information and outward appearance and detect information; Wherein, the information that signal collecting device reads can adopt the mode of transmitting successively, can first through the AOI function detection equipment, pass through the AOI appearance detecting device again, also can pass to simultaneously AOI function detection equipment and AOI appearance detecting device;
3) AOI function detection equipment and AOI appearance detecting device pass to the detection signal output device by Function detection information and outward appearance detection information, and when testing result was defective, the detection signal output device was made defective prompting; When testing result was qualified, the detection signal output device was made qualified prompting.
As a kind of preferred version, in step 3), the NG output device is made defective prompting, and the OK output device is made qualified prompting.The defective red LED lamp that prompts for that the NG output device is made lights, and alarm sends alerting signal; The qualified green LED lamp that prompts for that above-mentioned OK output device is made lights, the qualified bar code of bar code output device output, and be attached on thin film switch.Alarm is hummer.
Preferably, in step 3), detection record equipment records testing result when the detection signal output device is made defective prompting or qualified prompting, testing result is deposited in corresponding document, the staff can search according to warning message the typing situation of data like this, thereby find faulty goods, not there will be undetected or because personnel are unidentified, cause faulty goods to flow in client's hand.In step 1), signal collecting device is camera, and camera can clearly carry out function and outward appearance detects.
Above demonstration and described ultimate principle of the present invention, principal character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
