Detection equipment for adjusting pressure resistance of screen based on air pressure

Abstract

The invention relates to the technical field of touch screen detection, and discloses a detection device for adjusting the pressure resistance of a screen based on air pressure, the detection device comprises a frame body, the top of the frame body is movably connected with a ratchet plate, the inner part of the ratchet plate is elastically connected with a first ratchet, and the inner part of the top of the frame body is movably connected with a first plug body; the top end of the first plug body is fixedly connected with a pressing block, and the left end and the right end of the pressing block are fixedly connected with second ratchets. According to the detection equipment for adjusting the pressure resistance of the screen based on the air pressure, a pressing block is pressed to enable a first plug body to change the volume in a pressurizing cavity, so that the air pressure of the pressurizing cavity is increased, a second plug body is jacked and pressurized along with running fit of a cam and a first connecting rod, the downward pressure of a third plug body is increased and through moving cooperation of the first gear and the second connecting rod, the movable rack moves up and down. When the lifting tensioning roller abuts against the surface of the screen, the lifting block ejects the shifting block to enable the pressurizing cavity to be communicated with an internal gas path of the lifting block, and the ejector pin is pressed down by gas pressure for detection.

Description

technical field [0001] The invention relates to the technical field of touch screen detection, in particular to a detection device for adjusting the anti-pressure of the screen based on air pressure. Background technique [0002] As a brand-new interpersonal interaction technology, touch screen has been widely used in industry, medical treatment, communication, entertainment, education and other fields. Nowadays, touch screen has been widely used in various devices, such as smart phones or tablet computers. Capacitive In the production process of type touch screen, it is necessary to test the pressure resistance of the screen surface. The existing equipment has complex structure and cumbersome adjustment steps, which reduces the efficiency of adjustment and detection. Moreover, the existing detection equipment directly presses down on the screen surface through thimbles, rigid contact It is easy to cause damage to the surface of the screen, damage the touch screen, and incre...
