Embodiment Construction

[0028] Such as figure 1 with figure 2 , a kind of equipment 1 for automatically testing the touch device 10 includes: a fixture unit 101, which is a common fixture table with a fixed function; User operation, the support unit 103 is a device that provides control of the detection unit and fixes the position of the detection unit, and the data processing unit 104 is a device such as a single-chip microcomputer or computer processing control.

[0029] The clamp unit 101 is used to fix the touch device 10, which is a capacitive touch panel in this embodiment, and may also be other devices such as touch keys. The fixture unit 101 and the data processing unit 104 are connected through an inter-integrated circuit bus 32 (I2C, Inter-Integrated Circuit) interface, and the data connection between the fixture unit 101 and the touch device 10 is through the adapter 21 converted between the I2C interface .

[0030] The detection unit 102 is a plate electrode fixed on the support unit ...

Abstract

The invention discloses an automatic testing apparatus and a corresponding method used for a touch device. The automatic testing apparatus comprises a clamp unit (101) which is connected with the touch device (10) through data means and used for fastening the touch device; at least one detecting unit (102) which senses the touch device and is used for simulating the operation of users; a support unit (103) which is connected with the detecting unit and used for controlling and fastening the detecting unit; a data processing control unit (104) which is connected with the clamp unit and the support unit and used for receiving the data from the clamp unit and support unit and controlling the units through feedback. Adopting the automatic testing apparatus and the method used for touch devices can realize the automatic test to touch devices so as to enhance manufacturing efficiency, reduce failure products, raise the reliability of products and avoid the impact of manual errors.

Description

technical field [0001] The invention relates to the technical field of automatic testing, in particular to an automatic testing device and method for realizing a capacitive touch device. Background technique [0002] Touch devices have been widely used in electronic products, and the touch devices provide a simple, light and inexpensive indicating device. There are three types of existing touch devices: resistive, electromagnetic, and capacitive. Since the resistive touch device needs to concentrate the pressure points during operation, while the electromagnetic touch device needs to cooperate with a stylus with a battery for input, and in terms of performance and cost, capacitive touch devices surpass resistive and electromagnetic touch devices. touch device. The working principle of the capacitive touch device is to use the moment when the user's finger or conductor touches the touch device to generate a capacitive effect, because the core part of the capacitive touch se...
