Embodiments of the present invention

The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by a person of ordinary skill in the art without creative work shall fall within the protection scope of this application.

In this embodiment, a method for detecting a touch screen of an electronic product is provided, as shown in FIG. 1 and FIG. 5 to FIG. 7. The method for detecting a touch screen includes the following steps:

Step 101: Generate multiple detection points on the screen of the electronic product under test.

Among them, the tested electronic products include mobile phones, tablet computers or other products with touch screens.

Before testing the electronic product under test, it is necessary to install a preset detection software on the electronic product under test, and generate a plurality of regularly arranged detection points 20 on the screen of the electronic product under test through the detection software. The arrangement rule of 20 depends on the type and size of the touch screen of the electronic product. Specifically, the screen size of the tested electronic product is obtained, and a plurality of regularly arranged detection points 20 are generated according to the screen size of the tested electronic product.

The shape of the detection point 20 may be a circle or a square. The adjacent detection points 20 in the same row are tangent, and the adjacent detection points 20 in the same column are tangent to ensure that the detection points 20 can cover the touch area to the maximum extent. Among them, the size of the detection point 20 depends on the actual situation.

The detection point 20 covers the corresponding sensing device. With reference to FIG. 2, the touch screen includes a first metal coating 11, a second metal coating 12 and an insulating fulcrum 13. The insulating fulcrum 13 is arranged on the first metal coating. Between the layer 11 and the second metal coating 12, the first metal coating 11 is provided with a plurality of arc-shaped areas 111 correspondingly, and the detection point 20 covers the arc-shaped area 111; After the shaped area 111 is pressed, the first metal coating 11 and the second metal coating 12 contact to generate a touch signal.

Specifically, with reference to Figure 9, after the electronic product under test is placed in the detection position, the detection software has been activated. After the test function of the detection software is triggered, the detection software obtains the size of the touch screen and the type of touch screen. The inspection points 20 are arranged regularly to form a test base map, and then step 102 is executed.

Step 102: Trigger the auxiliary touch device to simulate touching the detection point according to a preset sliding track.

Wherein, the auxiliary touch device 30 may specifically be a robotic arm.

Among them, the preset sliding trajectory includes a full-screen sliding trajectory (as shown in Figure 5), an X-shaped sliding trajectory (corresponding to the X-shaped formed by two diagonal lines in Figure 6), and a sliding trajectory formed by superimposing a square and a diagonal line ( Figure 6).

In an actual application scenario, the type of the touch screen of the electronic product under test is acquired, and the sliding track is determined according to the type of the touch screen of the electronic product under test. When the detection points 20 corresponding to the touch screen are independent of each other, the sliding trajectory is a full-screen trajectory. Since the detection points 20 are independent of each other, the damage of a single detection point 20 will not affect other detection points 20. It is necessary to use a full-screen sliding method to detect all the detection points 20 to determine whether the touch screen function is good or bad.

Specifically, the touch screen is a self-capacitive screen, and the sensing circuit is mainly formed by electrodes 21. Each electrode 21 is independent of each other. The detection point 20 can be corresponding to the position of the electrode 21, as shown in FIG. The square is understood as the electrode 21, the circle is the detection point 20, and the detection point 20 covers the corresponding electrode 21.

When the detection points 20 of the touch screen influence each other in the horizontal and vertical directions, the sliding track is an X-shaped track. Since the detection points 20 influence each other in the horizontal and vertical directions, the damage of a detection point 20 will be associated with each other. Affect all detection points 20 on the row where the detection point 20 is located, and all detection points 20 on the column where the detection point 20 is located. In order to improve the detection efficiency, an X-shaped sliding track can be used for detection to determine whether the touch screen function is good or bad. .

Specifically, the touch screen is a mutual capacitance screen. As shown in FIG. 4, the sensing circuit includes a driving circuit 22 and a sensing circuit 23. The sensing circuit 23 and the driving circuit 22 are interleaved with each other. Take FIG. 4 as an example. The sensor circuit includes multiple rows of drive lines 22 and multiple columns of sensor lines 23. Each row of drive lines 22 drives each column of sensor lines 23 correspondingly. The sensor lines 23 and the drive lines 22 influence each other in the longitudinal and transverse directions, which can be The detection point 20 is arranged at the intersection of the sensing circuit 23 and the driving circuit 22, and one of the detection points 20 can simultaneously detect the quality of a row of driving circuits 22 and a column of sensing circuits 23.

In addition, touch screens include full screens, curved screens, and bangs screens. Most mobile phone touch screens are bangs or curved screens, which are blocked on the screen. When using the auxiliary touch device 30 to draw lines, you need to correspond to the bangs. Touch the area, trigger the auxiliary touch device 30 to make one more horizontal scribing on the bangs (the specific sliding track is shown in Figure 7), avoiding the position of the camera, earpiece, speaker and other components, generally drawn on the generated detection point 20 To avoid damage to the camera, earpiece, speaker and other components. This is due to the fact that the LCD display screen will not give up setting the original LCD in the position of the camera, earpiece, speaker and other components when it is cut into a mobile phone screen. The touch area of the notch part of the notch can also be detected.

Step 103: Obtain the connection between the touched detection points.

Step 104: Determine whether the touch screen of the electronic product under test is damaged according to the connection condition.

After the detection point 20 is swiped by the auxiliary touch device 30, if the touch of the detection point 20 area is normal, a touch signal will be generated, and the detection software will trigger the formation of a connection. If the touch function of the detection point 20 area is damaged, it will not be generated. The touch signal cannot form a connection. Therefore, the quality of the touch screen can be determined by the connection between the touched detection points 20.

Specifically, among the touched detection points 20, it is determined whether there is a target detection point that does not form a line between adjacent detection points 20; if it exists, the touch function of the touch area corresponding to the target detection point is invalid; if If it does not exist, the touched detection points 20 all generate touch signals, and the touch screen of the electronic product under test functions normally. In the actual state, whether there is a connection or not will present an intuitive effect on the display of the mobile phone, and this effect will be uploaded to the host computer 31 for corresponding record storage.

In this application, when detecting electronic products, the screen is divided into multiple detection points 20 by the detection software, and the auxiliary touch device 30 simulates the touch detection points 20, and then determines whether the touch screen is connected according to the connection between the detection points 20 Intact, no need to set up multiple hardware units, saving resources, simple detection method, short time-consuming, suitable for automatic detection.

The auxiliary touch device 30 is connected to the identification device 32, wherein the electronic product under test is pre-installed with detection software. When the electronic product under test is tested, the detection software is started and displayed on the screen of the electronic product under test. A plurality of inspection points 20 arranged regularly are generated.

In the actual application scenario, before testing the electronic product under test, it is necessary to install the preset detection software on the electronic product under test, and generate multiple regularly arranged detection points on the screen of the electronic product under test through the detection software. 20. Specifically, the screen size of the tested electronic product is obtained, and a plurality of regularly arranged detection points 20 are generated according to the screen size of the tested electronic product.

In addition, touch screens include full screens, curved screens, and bangs screens. Most mobile phone touch screens are bangs or curved screens, which are blocked on the screen. When using the auxiliary touch device 30 to draw lines, you need to correspond to the bangs. The touch area triggers the auxiliary touch device 30 to perform one more horizontal scribing on the bangs (the specific sliding track is shown in FIG. 7), and the touch area of the bangs of the bangs screen can also be detected.

The identification device 32 is used to obtain the connection status between the touched detection points 20; the host computer 31 is used to determine whether the touch screen of the tested electronic product is damaged according to the connection status, and further, The host computer 31 is also used to obtain the type of the touch screen of the electronic product under test, and plan the sliding track of the auxiliary touch device 30 according to the type of the touch screen.

Specifically, after the detection point 20 is swiped by the auxiliary touch device 30, if the touch of the detection point 20 area is normal, a touch signal will be generated, and the detection software will trigger the formation of a connection. If the touch function of the detection point 20 area is damaged, No touch signal is generated, and no connection can be formed. Therefore, the quality of the touch screen can be determined by the connection between the touched detection points 20.

Specifically, in the touched detection point 20, the host computer 31 is used to determine whether there is a target detection point that does not form a connection between adjacent detection points 20; if it exists, the touch corresponding to the target detection point The touch function of the area is invalid; if it does not exist, all touched detection points 20 generate a touch signal, and the touch screen function of the electronic product under test is normal.
