Embodiment 1

[0032] Such as figure 1 As shown, the drive mechanism 6 is a mechanical drive arm. The track of the touch pen 5 is controlled by the mechanical driving arm.

Embodiment 2

[0034] Such as figure 2 As shown, the drive mechanism 6 is a three-axis drive base with X-axis, Y-axis and Z-axis. The three-way driving is carried out through the three-axis driving seat to realize the track control of the touch pen 5 .

[0035] In addition, in order to prevent the high-intensity electromagnetic field from interfering with the electric control components of the driving mechanism 6, the electric control components of the driving mechanism 6 are shielded, and the shielding is sealed inside the metal matrix.

[0036] Finally, the driving mechanism 6 is provided with a camera mechanism 7 facing the capacitive touch screen 2 . It is convenient to monitor the testing process of the capacitive touch screen 2 remotely.

[0037] From the above description, it can be found that a touch device for the electromagnetic field radiation sensitivity test of a capacitive touch screen according to the present invention can test the limit field strength of the capacitive tou...

Abstract

The invention discloses a touch device for the electromagnetic field radiation sensitivity test on a capacitive touch screen. The touch device comprises an electromagnetic field isolation chamber, andthe capacitive touch screen is arranged in the electromagnetic field isolation chamber. The touch device comprises a touch mechanism arranged in the electromagnetic field isolation chamber, and a remote control mechanism arranged outside the electromagnetic field isolation chamber. The remote control mechanism is in control connection with the touch mechanism. The touch mechanism comprises a touch pen used for touching the capacitive touch screen, and a driving mechanism used for driving and controlling the touch pen to perform the touch test on the capacitive touch screen. According to the invention, the limit field intensity test can be carried out on the capacitive touch screen and the requirement of an aviation aircraft is met. The touch stability of the capacitive touch screen is guaranteed, and the safety is improved. The remote test mode is adopted, and the electromagnetic field isolation chamber provides isolation. Therefore, the test personnel cannot be influenced by the high-intensity field intensity, so that the health threat of the test personnel is completely eradicated. A safe testing environment is provided. The touch device is simple and reliable in design and easyto implement.

Description

technical field [0001] The invention relates to a touch device, in particular to a touch device for a capacitive touch screen electromagnetic field radiation sensitivity test, and belongs to the technical field of isolation supporting equipment for high field strength tests. Background technique [0002] Capacitive touch screens are widely used in consumer electronic devices because of their good transmittance and response sensitivity. To apply capacitive touch screens to military display devices, it is necessary to perform response standard magnetic field / electric field radiation sensitivity tests. However, due to the magnetic field / electric field radiation sensitivity test, high-intensity and high-frequency electromagnetic field radiation is extremely harmful to human health, and this test of the capacitive touch screen requires that the surface of the display screen be touched continuously during the test, and To monitor the working status of the touch screen in real time...
