Many terminal devices are equipped with touch screens, such as smart speakers, mobile phones, computers, etc., and users can interact with the terminal devices by clicking or swiping the touch screens. The quality of the touch screen performance directly affects the use state and the user experience of the terminal equipment. The quality of the touch screen of the terminal equipment provided with the touch screen needs to be detected before the terminal equipment leaves a factory, so that the touch screen is ensured to have higher precision.

In order to solve the above technical problem, an embodiment of the present invention provides a touch screen detection device. The position of the detection equipment relative to the equipment to be detected is determined by the control device according to the image of the equipment to be detected acquired by the acquisition device, the position of the equipment to be detected is adjusted by controlling the moving distances of the Y axial moving device and the R axial moving device, meanwhile, the position of the detection device is adjusted by controlling the moving distances of the X axial moving device and the Z axial moving device, and the control device controls the detection device to perform tests such as clicking, scribing and the like on the equipment to be detected according to a preset track, so that the quality of a touch screen of the equipment to be detected is evaluated.

The technical scheme of the utility model is described in detail in the following with reference to the accompanying drawings.

Fig. 8 is another schematic partial structure diagram of a touch screen detection device according to an embodiment of the present invention, which mainly includes a detection platform, a Y-axis moving device, and an R-axis moving device.

As shown in fig. 1 and fig. 2, in one possible implementation manner, the touch screen detection device provided by the present invention includes: the device comprises a machine base 100, a detection platform 200, an X axial moving device 300, a Y axial moving device 400, a Z axial moving device 500, an R axial moving device 600, a control device 900, a detection device 700 and a collection device 800.

Specifically, the Y-axis moving device 400 is disposed on the top of the base 100, the R-axis moving device 600 is disposed on the Y-axis moving device 400, and the inspection platform 200 is disposed on the top of the R-axis moving device 600. The testing platform 200 is used for placing a device under test. At least two support posts 110 are provided on the top of the housing 100, and the X-axis moving device 300 is disposed between the at least two support posts 110. The Z-axis moving device 500 is disposed on the X-axis moving device 300, and the detecting device 700 and the collecting device 800 are both disposed on the Z-axis moving device 500.

The collection device 800 transmits the collected image of the device under test to the control device 900. The control device 900 determines the moving distances of the X axial moving device 300, the Y axial moving device 400, the Z axial moving device 500, and the R axial moving device 600 according to the images, respectively, and controls the detection device 700 to detect the device to be detected, and simultaneously obtains the detection information of the device to be detected.

In one example, the device under test may be a terminal device with a touch screen, such as a smart speaker, a mobile phone, or a computer. The control device 900 includes a display, a keyboard for manual operation, a mouse and buttons, a motor controller, a computer (PC), a software control system, and the like. The control device 900 may establish a wireless communication connection with the device under test via a router or the like, or may establish a wired communication connection using a data line. In the process of detecting the device to be tested, a test track (such as a single point, an arc line, a rectangle, a triangle, a straight line, a plurality of points, a multi-section scribing line and the like), a scribing length, a pressure value and the like can be set through the control device 900, and the control device 900 can collect coordinate values of points or lines actually responded by the touch screen in real time during the test and compare and analyze the coordinate values with the preset test track, so that whether indexes of the touch screen, such as click sensitivity, click accuracy test, click precision test, click static jitter test, scribing sensitivity, scribing linearity, two-finger separation degree test, signal to noise ratio, response time and the like, meet the standard or not is judged, and then the quality of the touch screen is accurately evaluated.

In another example, the acquisition device 800 may be a camera. Before testing the device under test by using the detection apparatus 700, the control apparatus 900 needs to control the Y-axis moving apparatus 400 to move first, so that the device under test is located under the collection apparatus 800, thereby facilitating the collection apparatus 800 to obtain the image of the device under test and transmit the image to the control apparatus 900. The control device 900 may determine the position of the detection device 700 relative to the device under test from the image.

In a possible implementation manner, reference is made to a partial structure schematic diagram of the touch screen detection device shown in fig. 3 and 4. The detection device 700 includes a plurality of click components 710. The multiple click component 710 is primarily used for clicking, scribing, etc. (including but not limited to single point, multi-point, straight line, curved line, rectangular, etc.) testing of the touch screen.

In one embodiment, as shown in FIGS. 3 and 5, the structure of each click component 710 is the same. The clicking assembly 710 includes a first drive mechanism 711, a pressure sensor 712, a plurality of first limit sensors 713, a first telescoping rod 714, a slider 715, and a first clicking post 716.

Specifically, the first driving mechanism 711 is fixed to the Z-axis moving device 500, and the plurality of first limit sensors 713 are sequentially fixed to the Z-axis direction of the Z-axis moving device 500. The lead screw of the first driving mechanism 711 is provided with a sensing block 717, the sensing block 717 is provided with a first sensing piece 718, and the plurality of first limit sensors 713 can determine whether the lead screw of the first driving mechanism 711 moves a preset distance through the first sensing piece 718.

The bottom of the induction block 717 is provided with an L-shaped connecting member 719, the pressure sensor 712 is fixed at the bottom of the connecting member 719, one end of the first telescopic rod 714 is connected with the bottom of the pressure sensor 712, the other end of the first telescopic rod is fixed at the top of the sliding member 715, and one end of the first click column 716 is fixed at the top of the sliding member 715. When the control device 900 controls the first driving mechanism 711 to operate, the screw rod of the first driving mechanism 711 can move towards the connecting member 719 and apply pressure on the top of the connecting member 719. When the pressure value detected by the pressure sensor 712 is greater than the preset pressure value, the control device 900 controls the first driving mechanism 711 to stop operating.

For example, as shown in fig. 5, the sliding element 715 may be disposed on the Z-axis moving device 500 by a sliding rail. Specifically, the slide rail is fixed on the Z-axis moving device 500 along the Z-axis direction, and the sliding element 715 is connected to the slide rail in a sliding manner.

In another embodiment, the clicking assembly 710 further includes a first stop lever. One end of the first limiting rod is slidably connected to the bottom of the connecting member 719, and the other end is fixed to the top of the sliding member 715. The first stop bar may define a maximum travel distance of the slider 715 and the first click post 716.

Illustratively, the first drive mechanism 711 may be a lead screw motor. The second limit sensor 724 may be a photoelectric sensor. When the photoelectric sensor senses that an object (specifically, a sensing piece) is shielded, the position of the lead screw can be determined, the control device 900 can determine the relative position of the clicking assembly 710 relative to the device to be tested according to the position of the lead screw, and further determine whether the clicking assembly 710 moves to the limit position in the testing process of clicking and the like.

In one example, the first telescoping rod 714 includes a fixed rod and a resilient member. One end of the fixing rod is disposed at the bottom of the pressure sensor 712, and the other end of the fixing rod is fixedly connected with one end of the elastic member. The other end of the elastic member is fixed to the top of the sliding member 715. Illustratively, the resilient member may be a spring. The screw may move up and down while the first driving mechanism 711 is operated. When the screw rod moves downwards, the first sensing piece 718 on the sensing block 717 is driven to move downwards from the initial position. After the lead screw comes into contact with the connecting member 719, pressure is applied to the connecting member 719. When the pressure sensor 712 senses that the pressure is equal to or greater than the preset pressure value, the control device 900 may control the first driving mechanism 711 to stop operating. The pressure sensor 712 applies a corresponding pressure to the first telescopic rod 714, so that the sliding member 715 and the first click post 716 can be driven to move downwards, and the first click post 716 can click or press the touch screen of the device to be tested. The control device 900 can respectively control the X-axis moving device 300 and the Y-axis moving device 400 to move, so that the pointing component 710 performs tests such as scribing on the touch screen of the device to be tested. After the test is completed, the control device 900 controls the first driving mechanism 711 to operate, so that the lead screw of the first driving mechanism 711 moves upward to the initial position, and the slider 715 and the first click post 716 are reset.

It should be noted that the control device 900 can control the maximum distance of the up-and-down movement of the lead screw by controlling the number of turns of the first driving mechanism 711, so as to control the pressure value applied by the lead screw to the connecting member 719, and further control the pressure value of the first click column 716 pressing the touch screen of the device under test. However, in order to further limit the moving distance of the lead screw of the first driving mechanism 711 and prevent the overshoot motion of the lead screw, the present invention determines whether the lead screw moves by a preset distance (i.e., a distance between the initial position and the final position) by providing a plurality of limit sensors. As shown in fig. 5, assume that the pointing assembly 710 includes two first limit sensors 713. The two first limit sensors 713 are vertically disposed on the Z-axis moving device 500 in the Z-axis direction. When the screw of the first driving mechanism 711 is located at the initial position, the first sensing piece 718 is inserted into the first position-limiting sensor 713 located above. When the screw rod of the first driving mechanism 711 moves downward, the first sensing piece 718 also moves to the first position-limiting sensor 713 located below along with the screw rod. When the first position-limiting sensor 713 located at the lower side detects the blocking of the first sensing piece 718, it indicates that the lead screw of the first driving mechanism 711 has moved by the preset distance, and at this time, the control device 900 may control the first driving mechanism 711 to stop operating. Similarly, after the test is completed, the control device 900 controls the first driving mechanism 711 to operate, so that the screw rod of the first driving mechanism 711 moves upward, and when the first position-limiting sensor 713 located above detects the shielding of the first sensing piece 718, it indicates that the screw rod of the first driving mechanism 711 has moved from the final position to the initial position, and the control device 900 may control the first driving mechanism 711 to stop operating.

In another possible implementation, as shown in fig. 4, 6 and 7, the detection apparatus 700 further includes a two-finger separation assembly 720. The two-finger separating component 720 is mainly used for simulating the line drawing operation when the user moves in opposite directions on the touch screen by using two fingers at the same time (for example, zooming in the picture by moving the two fingers in the opposite directions, zooming out the picture by moving the two fingers in the opposite directions, etc.).

In one embodiment, the two-finger separating assembly 720 includes a second drive mechanism 721, a first actuator 722, two clicking mechanisms 723, a plurality of second limit sensors 724, and two synchronizing wheels 725. A second drive mechanism 721 and a plurality of second limit sensors 724 are fixed to the Z-axis moving device 500. The screw rod of the second driving mechanism 721 is provided with a fixing plate 726, and the bottom of the fixing plate 726 is provided with a fixing frame 727. The first driver 722 and the two synchronizing wheels 725 are disposed on a side of the fixing frame 727 away from the Z-axis moving device 500, and the second driving mechanism 721 is used for driving the two clicking mechanisms 723 to move along the Z-axis direction.

The first driver 722 is used for driving the two synchronous wheels 725 to rotate so as to drive the synchronous belt 7251 arranged on the two synchronous wheels 725 to move. One of the two click mechanisms 723 is arranged on a synchronous belt 7251 at the upper ends of the two synchronous wheels 725 through a first sliding block 7281, and the other is arranged on a synchronous belt 7251 at the lower ends of the two synchronous wheels 725 through a second sliding block 7282, so that when the synchronous belt 7251 moves, the two click mechanisms 723 can be driven to move reversely (including moving backwards and moving towards each other) along the Y-axis direction. The plurality of second limit sensors 724 are used to determine whether the two clicking mechanisms 723 have moved a preset distance.

For example, as shown in fig. 6 and 7, the first sliding block 7281 and the second sliding block 7282 can also be slidably connected to the fixing frame 727 through a sliding rail. Specifically, the slide rail is fixed to the fixing frame 727 along the Y-axis direction (i.e., the horizontal direction), and the first sliding block 7281 and the second sliding block 7282 are slidably connected to the slide rail, respectively.

It will be appreciated that in the two-finger separator assembly 720 shown in fig. 6 and 7, the first actuator 722, in operation, may rotate one of the synchronizing wheels 725, thereby rotating the timing belt 7251 clockwise or counterclockwise and thus rotating the other synchronizing wheel 725. If the synchronous belt 7251 rotates clockwise, the synchronous belt 7251 above the two synchronous wheels 725 moves back to back with the synchronous belt 7251 below the two synchronous wheels 725, so that the two click mechanisms 723 can be driven to move back to back simultaneously. If the synchronous belt 7251 rotates counterclockwise, the synchronous belt 7251 above the two synchronous wheels 725 and the synchronous belt 7251 below the two synchronous wheels 725 move toward each other, so that the two click mechanisms 723 can be driven to move toward each other at the same time.

By way of example and not limitation, the second driving mechanism 721 may be a lead screw motor, and the number of turns of the lead screw motor determines the moving distance of the lead screw, and thus the moving distance of the two-finger separating assembly 720 in the Z-axis direction. The second limit sensor 724 may be a photoelectric sensor. The first actuator 722 may be a motor, and the number of rotations of the motor determines the number of rotations of the timing wheel 725, thereby determining the moving distance of the timing belt 7251, and thus the reverse moving distance of the two-finger separating assembly 720 in the Y-axis direction.
