An embodiment of the present application provides an eye-protecting carbon crystal screen multi-contact positioning test device, which relates to the technical field of contact test devices. The eye-protecting carbon crystal screen multi-contact positioning testing device includes: a support moving mechanism, a workpiece positioning mechanism and a testing mechanism. The support movement mechanism includes an operating platform, a first lead screw, a first support seat, a first hand wheel, a transverse guide rod and a second support seat, and two groups of the first support seats and the second support seats are respectively installed On the top of the operating platform, both ends of the first lead screw are respectively rotatably connected to the two first support seats. The hand moves the touch bar at the bottom of the transparent plate to move along the route to be detected to realize the multi-point test screen. At this time, the transparent plate runs through the moving path. Since the screen is always positioned during the test, the moving touch bar will not drive the touch screen to move, making the multi-touch test more accurate when the touch bar moves.
Description
technical field [0001] The present application relates to the technical field of contact testing devices, in particular, to an eye-protecting carbon crystal screen multi-contact positioning testing device. Background technique [0002] With the rapid development of electronic technology, the tactile feedback system on the touch screen can drive various connecting devices according to the pre-programmed program, and can be used to replace the mechanical button panel. As an input device, the touch screen is a simple, convenient and natural way of human-computer interaction. It is mainly used in public information inquiry, industrial control, military command, electronic games, multimedia teaching, etc. [0003] After the eye-protecting carbon crystal touch screen is produced, it needs to be tested according to multiple contacts. When testing the contacts in the current manual method, there are special positioning and fixing devices in the touch screen to be tested, and it is d...
