Method four adopts the test of product line property testing instrument more directly perceived, and the test effect is better, but test speed is slower, and bulk article needs all tests, takes the testing efficiency of the method lower.
The situation of comprehensive above-mentioned various handset touch panel test technologies, the testing electrical property device that has touch-screen now is improved and innovates is very necessary.
Summary of the invention
In view of above-mentioned the deficiencies in the prior art, the purpose of this utility model is exactly, design a kind of capacitive touch screen proving installation that adopts the anthropomorphic hand of multi-point mould to touch handset touch panel, the handset touch panel test process is reached: simple, convenient and suitable batch process.
The purpose of this utility model is to realize by such technical scheme, a kind of capacitive touch screen proving installation is characterized in that: described device comprises by monolithic processor controlled test chip circuit, instrument casing, pneumatic touch head, tracheae, the touch headstock, touches a floating holder and testing touch screen interface board;
The test chip circuit places in the instrument casing, and the test chip circuit connects the built-in touch screen interface of testing touch screen interface board by terminal interface and winding displacement; Pneumatic touch head is made of metal tube and thin metal dish cap, on the screw thread of metal tube bottom, screw in thin metal dish cap, thin metal dish cap surface is pasted one deck conductive rubber, metal tube upper end grafting tracheae, the tracheae other end connects air pump, tested touch-screen is positioned on the testing touch screen interface board, before the test, make the whole measured point of a pneumatic touch gap contact touch-screen, during test, when tracheae connects source of the gas, under the effect of air pressure, make and adopt the thin metal dish cap distortion of Thin Elastic metal material to protrude the conductive rubber anthropomorphic dummy finger presses touch-screen measured point of thin metal dish cap surface; Control the break-make of tracheae source of the gas by test chip circuit control electric air pump switch;
The beneficial effect that the utility model produces is: the test position of capacitive touch screen proving installation covers whole touch scope, research and development test products parameter consistency is carried out statistical study, can directly provide the non-defective unit defective products judges, judge non-defective unit and defective products according to statistic analysis result, take the high suitable batch production of testing efficiency of the method; Accurate testing degree and work efficiency have been improved.

Embodiment
As shown in Figure 1 to Figure 3, the capacitive touch screen proving installation comprises by monolithic processor controlled test chip circuit, instrument casing 6, pneumatic touch 1, tracheae 2, touches the headstock 3, touches a floating holder 4 and testing touch screen interface board 5;
Also be provided with liquid crystal display terminal 7 and tolerance on the instrument casing 6 and adjust knob 8; The test chip circuit places in the tool housing 6, connects the built-in touch screen interface of testing touch screen anchor clamps by test circuit terminal interface plate 5 and winding displacement and is connected with product so that product is tested; It is copper that thin metal dish cap 12 adopts the Thin Elastic metal material.
The utility model is to detect at the electrical property that capacitive touch screen carries out.According to driver chip correlation technique parameter, design and produce capacitive touch screen proving installation device, the every technical feature of capacitive touch screen is detected.
The establishment corresponding testing program makes test operation simple, convenient, operator is opened corresponding test procedure on computers, computer and tester are communicated with the back operator and put into product to be tested on request in tools, press testing button, tester just can be tested automatically, and providing result of determination according to test data, computer carries out record to test data simultaneously.Operator can reach test purpose according to result of determination with the placement of classifying of non-defective unit, defective products.Record in the computer can be convenient to that the engineering staff effectively follows the trail of and bad analysis.
Auto test flow:
[test 1] power test: power input short circuit, open test
[test 2] connects test: the test board check of communicating by letter with the touch-screen module
[test 3] module version test: module hardware and software version checking
[test 4] passage short-circuit test: FPCB flexible-cable and chip short-circuit testing
