Capacitive touch screen conducting film probe type electrical testing equipment

Abstract

The invention relates to capacitive touch screen conducting film probe type electrical testing equipment which comprises a workbench, a carrier plate used for placing a touch screen, a support arranged above the workbench, a TX testing assembly and an RX testing assembly, wherein the TX testing assembly and the RX testing assembly are arranged on the support. Vacuum adsorption nozzles which are distributed at equal intervals are arranged above the carrier plate, and the touch screen is adsorbed and fixed through the vacuum adsorption principle; the TX testing assembly and the RX testing assembly can move transversely and longitudinally relative to the workbench at the same time, and then alignment with a touch screen conductive film test position is achieved. The problem that an existing electric testing machine cannot meet the testing requirement of a touch screen conducting film or is low in testing efficiency is solved, the multiple sections of movable testing pressure heads and short-circuiting bars are adopted, transverse and longitudinal adjustment can be achieved through each testing pressure head and short-circuiting bar, switching of testing requirements of touch screen conducting films of different models is achieved, electric testing of touch screen conducting films of different models can be achieved, and the testing efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of touch display modules, in particular to a capacitive touch screen conductive film probe type electric measuring device. Background technique [0002] Touch screen, also known as "touch screen" or "touch panel", is an inductive liquid crystal display device that can receive input signals such as contacts. When touching the graphic buttons on the screen, the tactile feedback on the screen The system can drive various connecting devices according to pre-programmed programs, which can be used to replace mechanical button panels, and to create vivid audio-visual effects through liquid crystal display screens. As the latest computer input device, the touch screen is currently the simplest, most convenient and natural way of human-computer interaction. It endows multimedia with a new look and is a very attractive new multimedia interactive device. [0003] At present, the touch screen is made of TX touch film ...

AI Technical Summary

Problems solved by technology

Existing electrical testing machines usually use a single test indenter. The electrical testing machine cannot meet the test requirements or the test efficiency is low. An electrical testing device compatible with various sizes and multi-segment testing is needed.

For example, attach figure 1 Among them, the TX touch film has 4 test positions, and the RX touch film has 3 test positions. This touch film has products from 23 inches to 110 inches. The existing electrical testing equipment cannot meet the test requirements.
