[0030] Working principle: The operator places the touch screen product to be tested into the positioning component 7 on top of the placement plate 3 through the transport slot 12. The touch screen product needs to be accurately embedded into the positioning slot 73 in the placement slot 71 and connected to the data cable 74 through the digital interface 72 to realize data communication between the product and the central control unit 54. After starting the switch 51 and setting the detection parameters through the control knob 52, the card reader 53 performs identity verification. The central control unit 54 activates the cylinder a6 to drive the movable plate 1 to slide down along the guide rod b13. The fixing ring b14 at the bottom of the movable plate 1 cooperates with the guide rod b13 to ensure the stability of the movable plate 1. During the movement, the baffle 10 limits the sliding of the movable plate 1. When the movable plate 1 moves down to the working position, the printing component 4 first contacts the product. Under the guidance of the directional rod 42, the pressure plate 43 slides down along the template 45 and presses the edge of the product. The auxiliary positioning column 46 further ensures the accurate position of the product. The cylinder b85 drives the pressing plane 81 to move down along the guide rod a83, so that the detector 84 contacts the surface of the touch screen product. The detector 84 detects the touch sensitivity, multi-touch function and other parameters of the touch screen and transmits the data to the central control computer 54 for analysis and processing in real time.

[0031] If the test result is qualified, cylinder C15 drives the printing component 4 to move, and the fixed block 41 moves down with cylinder C15, causing the pressure plate 43 to slide on the template 45. The qualified product is marked by the pattern on the template 45. If the test is unqualified, the central control unit 54 will issue an alarm signal. After the test is completed, cylinder A6 drives the movable plate 1 to move up and reset. The operator takes out the tested product through the transport groove 12 to complete one work cycle. The side plate 16 and the front plate 11 are fixedly connected by the mounting block 9 to form a closed frame, which protects the internal components and provides operating space.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
