Embodiment Construction

[0010] As shown in the figure, the components of the present invention are as follows: working status indicator light 1, test button 2, power switch 3, X direction adjustment head 4, X\Y fine-tuning platform 5, stage 6, upper camera 7, upper camera display Screen 9, lower camera display screen 8, upper thread needle mounting plate 10, Y direction adjustment head 11.

[0011] A fixed adjustment device for a fine-pitch needle board is provided on the stage, the fine-pitch needle board is connected to the pins of the capacitive touch screen to be detected, and the fine-pitch needle board is electrically connected to the detection circuit.

[0012] The micro-pitch wire needle board is the lead-out wire needle (wire needle) on the insulating board, and the wire needle corresponds to the pin position of the capacitive touch screen to be tested. The wire needle is 2mm higher than the insulation board, which is a single row of metal probes, the surface of which is gold-plated or other...

Abstract

A capacitive touch screen detection device comprises a detection circuit, a controller, an upper fine-pitch lead board, a lower fine-pitch lead board, interface boards, a high-precision X-Y fine adjustment platform, a stage, an upper binocular microscope camera and a lower binocular microscope camera and display screens thereof. The stage for holding a capacitive touch screen to be detected is arranged on the high-precision X-Y fine adjustment platform, the microscope cameras are respectively arranged above and below the capacitive touch screen to be detected and connected to the display screens, fixing regulating devices of the upper fine-pitch lead board and the lower fine-pitch lead board are arranged on the stage, and the upper fine-pitch lead board and the lower fine-pitch lead board are connected with pins of the capacitive touch screen to be detected, and are connected to a detection circuit through the interface boards. The capacitive touch screen detection device is reliable in connection and long in service life since FPCs (flexible printed circuits) are replaced by fine-pitch leads.

Description

technical field [0001] The invention relates to a detection device for a capacitive touch screen. Background technique [0002] With the hot sales of iPhones, capacitive touch screens are becoming more and more well known. Its light transmittance and clarity are better than resistive screens, and the operation of capacitive screens can be operated without pressure and light touch. More and more resistive touch screen manufacturers have invested energy and funds to shift the production focus to the production of capacitive touch screens for supporting mobile phone manufacturers. Due to the different technologies used, the detection method of capacitive touch screen is different from that of resistive touch screen. The old detection equipment cannot be used, and often can only be detected one by one by manual visual inspection and binding chips. Typically, FPC soft wiring is used for bonding. This makes the production efficiency extremely low and the production cost is quite...
