Description

Touch screen test device

【Technical field】

The invention relates to a test device, in particular to a touch screen test device.

【Background technique】

For electronic products such as notebook computers, digitizer (digital conversion) touch screens have appeared. This type of touch screen needs a scribing test, that is, a magnetic pen is used to continuously scribe the line in the limited area of the touch screen, and the signal generated after the scribing is exported. The test computer shows whether the drawn lines are continuous to judge whether the touch screen is qualified. Of course, for the touch screen of the digitizer, the test standard is that the magnetic pen is required to do the above-mentioned scribing test at a distance from the screen, and the test can still pass.

However, at present, for the above tests, the scribing test is usually performed on the assembled electronic products. If the touch screen is found to be defective, it takes a lot of manpower and material resources to disassemble the touch screen, and then perform the action of replacing the screen. The cost is relatively high. high and inefficient.

In view of this, it is necessary to develop a touch screen testing device to solve the above problems.

【Detailed ways】

Please refer to FIG. 1 and FIG. 2 in conjunction. FIG. 1 is a schematic structural diagram of a preferred embodiment of a touch screen test device of the present invention, and FIG. 2 is a schematic diagram of a preferred embodiment of the touch screen test device of the present invention. Schematic diagram of the breakdown structure.

In order to achieve the above purpose, the touch screen test device provided by the present invention includes:

The base 100 has several positioning shafts 101 on its upper surface, the base 100 has a boss 102 near one end, and the boss 102 has a pivot hole;

The lower bottom plate 103 is arranged on the base 100, and the bottom surface of the lower bottom plate 103 is butted with the positioning shaft 101;

The guide plate 104 is disposed above the lower bottom plate 103 , and the touch screen 105 (take the touch screen of digitizer as an example) is clamped between the lower bottom plate 103 and the guide plate 104 , one end of the guide plate 104 is There is a pivot, the pivot is pivoted to the pivot hole on the base 100 , the guide plate 104 has a penetrating guide groove 106 , and the guide groove 106 corresponds to the scribing test of the touch screen 105 area.

Using the touch screen testing device of the mold of the present invention, the lower base plate 103 is installed on the base 100, the touch screen 105 is clamped between the guide plate 104 and the lower base plate 103, and the lower base plate 103 is rotated. The guide plate 104 is pressed against the touch screen 105, and the magnetic pen moves along the guide groove 106 to make a continuous scribing motion, thereby completing the scribing action. Of course, in order to ensure that the magnetic control pen and the touch screen 105 can pass the test within an effective distance during operation, the magnetic control pen can maintain an effective distance from the touch screen 105 when drawing a line. Since the touch screen 105 is subjected to a scribing test before being assembled to an electronic product, it is avoided that the scribing test after assembly is unqualified, and the screen needs to be disassembled to replace the screen, thereby saving manpower and material resources.
