Abstract
The utility model provides a kind of testing touch screen machine, comprise frame, test module, display module and card extender, test module and display module are arranged in frame, card extender is test module and tested touch-screen in succession, it is characterized in that: test module is the circuit comprising microcomputer chip AT89C52, by exploitation single-chip microcomputer control program, be combined with SCM peripheral circuit, the each passage of touch-screen is contacted respectively by probe, the each passage of touch-screen is connected with testing touch screen machine test module, connect into voltage comparator, so just can measure each interchannel resistance value and conducting situation exactly, avoid and detect with the artificial multimeter that uses, detection efficiency is high, accuracy rate is high.
Description
Technical field
The utility model relates to a kind of Touch-screen testing equipment, particularly relates to a kind of testing touch screen machine.
Background technology
Touch-screen is more and more widely used as one display and input electron device, and the quality of touch-screen directly affects it and uses, so, to detect the touch-screen of processing, to judge the quality of touch-screen in the production run of touch-screen.
The terminal pin (PIN) of touch-screen is from several to tens have, short circuit must not be had between each circuit of touch-screen, and the resistance of the every bar induction line of capacitance plate can not exceed the value of regulation, therefore, the capacitance plate produced should to detect between PIN and PIN whether short circuit, also will detect the resistance value of every bar induction line.
Because the quantity of producing touch-screen is many, even sampling observation, its workload detecting touch-screen is also very large, further, mostly the method detecting at present touch-screen is to adopt digital display type multimeter: any two PIN checking capacitance plate with red, the black meter pen of multimeter one by one, until to check out between each PIN whether short circuit, do like this, because PIN not only checks that speed is very slow too much, but also inaccurate, easily go wrong; When checking the resistance value of every bar induction line, be also a PIN and this another end points of PIN circuit of contacting every bar induction line with red, the black meter pen of multimeter, check that speed is slow, inaccurate, efficiency is low.
Summary of the invention
The purpose of this utility model is to provide a kind of testing touch screen machine, and this testing touch screen machine testing touch-screen efficiency is high, and accuracy rate is high.
In order to achieve the above object, testing touch screen machine of the present utility model, comprise frame, test module, display module and card extender, test module and display module are arranged in frame, card extender is test module and tested touch-screen in succession, it is characterized in that: test module is the circuit comprising microcomputer chip AT89C52.
Test module with microcomputer chip AT89C52 for core, by exploitation single-chip microcomputer control program, be combined with SCM peripheral circuit, contact each passage of touch-screen respectively by probe, each passage of touch-screen is connected with testing touch screen machine test module, connects into voltage comparator, so just can measure each interchannel resistance value and conducting situation exactly, avoid and detect with the artificial multimeter that uses, detection efficiency is high, and accuracy rate is high.
Described testing touch screen machine, is characterized in that: the circuit board contact pilotage on card extender is consistent with the contact pilotage specification of tested touch-screen.
Described display module is made up of pilot lamp and hummer, is used for showing the result that testing touch screen machine records touch-screen.
Described frame is support and the link of testing touch screen machine.
In the use procedure of testing touch screen machine, according to the online product type needing test, the welding circuit board with test product same size on test machine card extender, be connected on test machine by the wire of card extender, circuit board during test on product is connected with the circuit board on test machine card extender.
Testing touch screen machine testing touch-screen efficiency of the present utility model is high, and accuracy rate is high.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of the test module embodiment of the utility model testing touch screen machine.
Embodiment
The embodiment of the utility model testing touch screen machine comprises frame, test module, display module and card extender, frame is support and the link of testing touch screen machine, test module and display module are arranged in frame, card extender is test module and tested touch-screen in succession, see Fig. 1, test module is the circuit composition comprising microcomputer chip AT89C52, circuit board contact pilotage on card extender is consistent with the contact pilotage specification of tested touch-screen, display module is made up of pilot lamp and hummer, is used for showing the result that testing touch screen machine records touch-screen.
Test module with microcomputer chip AT89C52 for core, by exploitation single-chip microcomputer control program, be combined with SCM peripheral circuit, contact each passage of touch-screen respectively by probe, each passage of touch-screen is connected with testing touch screen machine test module, connects into voltage comparator, so just can measure each interchannel resistance value and conducting situation exactly, avoid and detect with the artificial multimeter that uses, detection efficiency is high, and accuracy rate is high.
In the use procedure of testing touch screen machine, according to the online product type needing test, the welding circuit board with test product same size on test machine card extender, be connected on test machine by the wire of card extender, circuit board during test on product is connected with the circuit board on test machine card extender.
By comparing, using multimeter test products, needing 2 people's operations, testing a granule product and need 10 minutes consuming time, with testing touch screen machine test machine test identical product of the present utility model, only about 1 minute consuming time, and only need 1 people's operation, and measuring accuracy is high.
Testing touch screen machine testing touch-screen efficiency of the present utility model is high, and accuracy rate is high, applying of it, has positive meaning to raising touch-screen quality and throughput rate.
