[0045] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0046] In order to solve the problems existing in the related art, an embodiment of the present disclosure provides a testing device, which includes a mechanical arm, a first rotating component and at least one test pen, wherein the first rotating component is arranged at the free end of the mechanical arm, the first output end of the first rotating component is connected to the test pen, and the at least one test pen is used to test the display function of the electronic device, and the first output end can rotate around a preset rotating shaft, and the axial direction of the first preset rotating shaft is parallel to the horizontal plane. In the present disclosure, the first rotation can drive the test pen to rotate around the first preset rotating shaft parallel to the horizontal plane, so that the test pen can be tilted relative to the display screen of the electronic device, which can better simulate human hands for testing, and can also adjust the number of test pens in contact with the display screen, thereby improving the test accuracy and broadening the test scenarios.

[0047] According to an exemplary embodiment of the present disclosure, Figure 1 As shown, an embodiment of the present disclosure provides a testing device, which is used to test the display function of an electronic device, such as a smart phone, a tablet computer, a laptop computer, a smart watch, etc. It is understandable that with the continuous development of technology, the display screens of existing electronic devices usually have the function of touch operation. In order to ensure the factory yield rate and reduce or avoid customer complaints, the display function and screen structure strength of the electronic device need to be tested before it leaves the factory, such as by clicking or sliding.

[0048] like Figure 1As shown, the testing device includes a mechanical arm 10 and at least one test pen 30. The mechanical arm 10 includes a fixed end and a free end 11. The test pen 30 is arranged at the free end 11 of the mechanical arm 10. The fixed end is usually fixedly installed on a working platform. The free end 11 can move arbitrarily within a certain spatial range relative to the fixed end, thereby driving the test pen 30 to translate and rise and fall arbitrarily within a certain spatial range, so that at least one test pen 30 can contact any position of the display screen of the electronic device to be tested, thereby testing the display function of the electronic device.

[0049] For example, reference Figure 1 , when the robot arm 10 drives the test pen 30 up and down ( Figure 1 When the mechanical arm 10 drives the test pen 30 to contact the display screen and drives the test pen 30 in the horizontal direction (z direction shown in FIG), the test pen 30 can repeatedly click the display screen of the electronic device, such as simulating the user's single click and double click operation of the display screen. Figure 1 The movement is performed in the plane where the x direction and y direction are located (as shown in the figure), for example, the operation of a user sliding a display screen can be simulated.

[0050] refer to Figures 1 to 3 The testing device further includes a first rotating assembly 20, which is disposed between the free end 11 of the mechanical arm 10 and the testing pen 30. Figures 1 to 3 The first rotating assembly 20 has a first output end 21, which is connected to the test pen 30. The first output end 21 can rotate around a first preset rotating shaft 211. The axial direction of the first preset rotating shaft 211 is parallel to the horizontal plane. The first rotating assembly 20 can drive the test pen 30 to rotate to adjust the angle between the test pen 30 and the plane where the display screen is located. For example, Figure 2 The test pen 30 is shown in a vertical position ( Figure 1 z direction) state, Figure 3 The test pen 30 is shown in a tilted state. For example, the first rotating assembly 20 drives the test pen 30 to move along direction a (refer to Figure 3 ) is rotated 30° (just as an example, it can also be any angle such as 16°, 34°, etc.), then Figure 2 The displayed status switches to Figure 3 Status shown.

[0051] In one example, when a user uses a finger to operate the display screen of an electronic device, even if they are all click (single-click) operations, the way the finger presses may be different in different usage scenarios. For example, when a user unlocks an electronic device with an under-screen fingerprint, in order to ensure the accuracy of the unlocking, the user usually uses the finger that recorded the fingerprint information (such as the front of the thumb) to press the display screen. In this case, the pressing contact area is larger and the force is perpendicular to the display screen. For another example, when a user needs to use a finger (such as the side of the thumb) to trigger a button farther away, the contact area between the finger and the display screen is smaller. Reference Figure 2 and Figure 3 , Figure 2 The test pen 30 shown is in a vertical position so as to have a larger pressing area. Figure 3 The test pen 30 shown is in a tilted state and thus has a smaller pressing area. Therefore, during the test process, the test pen 30 can be driven by the first rotating component 20 to switch between the vertical state and the tilted state, thereby simulating various manual operation methods.

[0052] In another example, there are some electronic devices on the market whose display screens have curved structures, such as the display screens of smart phones including micro-curved screens, waterfall screens, etc. It can be determined that if the test pen 30 is always in a vertical state, the test pen 30 can only have a good test effect on the flat surface of the display screen, and the test effect on the curved surface area is poor or cannot be tested. Therefore, when it is necessary to test the curved surface area of ​​the display screen of the electronic device, the first rotating component 20 can drive the test pen 30 to rotate around the first preset rotating shaft 211 at a certain angle, so that the test pen 30 is in an inclined posture so that the curved surface area can be tested.

[0053] In another example, it can be determined that the touch operation is not limited to single-finger click. Some functions of the electronic device may require multiple fingers to press and slide the display screen at the same time to trigger, such as two-finger (three-finger) sliding the upper limit of the screen, two-finger (three-finger) tapping to take a screenshot or start recording, etc. The above operation logic is only used as an example to assist in understanding the technical solution of the present disclosure, and does not limit the technical solution, usage, etc. of the present disclosure. Figure 5 and Figure 6 , showing that the first output end 21 of the first rotating assembly 20 is connected to three test pens 30 at the same time, Figure 5 The first rotating assembly 20 is in a first preset state, and the plane where the bottom ends of the multiple test pens 30 are located is stacked along a direction perpendicular to the plane to be tested (the plane where the display screen is located, the working plane). That is, when the test pens 30 are in a vertical state, the heights of the three test pens 30 are inconsistent. Figure 5In the state shown, when the mechanical arm 10 drives the test pen 30 to operate on the display screen, only the test pen 30 with the lowest height can contact the display screen, so that only single-finger click, slide and other operations can be completed. When the test device needs to test the multi-finger operation function of the electronic device, the first rotating component 20 can be controlled to drive the three test pens 30 to rotate around the first preset rotating shaft 211 (reference Figure 3 ) is rotated to the second preset state, so that the bottom ends of the three test pens 30 are at the same horizontal plane (reference Figure 6 ), when the robotic arm 10 drives the test pen 30 to operate on the display screen, the three test pens 30 can all contact the display screen, thereby completing operations such as three-finger (multi-finger) clicking and sliding.

[0054] In another example, it can be determined that during the process of touching the display screen, the user's fingers may be in different states, such as dry, wet, wearing gloves, etc. Therefore, multiple test pens 30 can be set on the first rotating component 20, and the bionic contacts 34 (described in detail later) used by the multiple test pens 30 to contact the display screen are different. The first rotating component 20 drives the test pens 30 to rotate around the first preset rotating shaft 211, so that the test pens 30 equipped with various bionic contacts 34 contact the display screen respectively, thereby simulating fingers in various states, without the need for staff to manually replace the bionic contacts 34, which is conducive to improving the test efficiency.

[0055] In the disclosed embodiment, the first rotation can drive the test pen to rotate around a first preset axis parallel to the horizontal plane, so that the test pen can be tilted relative to the display screen of the electronic device, which can better simulate human hands for testing and can also adjust the number of test pens in contact with the display screen, thereby improving test accuracy and broadening test scenarios.

[0056] In an exemplary embodiment, Figures 1 to 4 As shown, an embodiment of the present disclosure provides a testing device, which is used to test the display function of an electronic device. The testing device includes a robotic arm 10, a first rotating component 20 and a testing pen 30. The first rotating component 20 is arranged at the free end 11 of the robotic arm 10. The first output end 21 of the first rotating component 20 is connected to the testing pen 30. The first output end 21 can rotate around a preset rotating axis, and the axial direction of the first preset rotating axis 211 is parallel to the horizontal plane.

[0057] In this embodiment, Figure 8 and Fig. 9 As shown, the test pen 30 includes an outer shell 31 , a pen core 32 and a buffer member 33 .

[0058] refer to Figure 8 and Fig. 9, the outer shell 31 is connected to the first output end 21 of the first rotating component 20, the outer shell 31 is barrel-shaped and defines a receiving chamber 311, the pen core 32 and the buffer 33 are both arranged in the receiving chamber 311, the buffer 33 has elastic deformation ability, in the elastic deformation direction of the buffer 33, one end of the buffer 33 is connected to the outer shell 31, and the other end is connected to the pen core 32. It can be seen from the above that the buffer 33 can be elastically deformed, so that the outer shell 31 and the pen core 32 form a movable connection. For example, taking the click operation as an example, in the process of the robot arm 10 driving the test pen 30 to approach and press the display screen, the pen core 32 will remain relatively motionless after contacting the display screen, and as the robot arm 10 continues to move downward ( Figure 1 The robot arm 10 will drive the outer shell 31 closer to the display screen. At this time, the buffer member 33 will provide a buffering function to prevent the display screen from being damaged by excessive pressure, thereby improving the fault tolerance and safety of the test process.

[0059] In one example, reference Fig. 9 The buffer member 33 may be a compression spring. This does not limit the technical solution of the present disclosure. In some optional implementations, the buffer member 33 may also be an item made of elastic materials such as a rubber block or a silicone block.

[0060] Among them, reference Fig. 9 The test pen 30 also includes a bionic contact 34, which is arranged at one end of the pen core 32 away from the buffer 33, and the bionic contact 34 is detachably connected to the pen core 32. Removable connections include threaded connections, snap connections, magnetic connections, adhesive connections, etc. The bionic contact 34 has an area and texture similar to those of a human hand. For example, the bionic contact 34 can be made of materials such as silicone and conductive cloth. The bionic contact 34 is arranged to be detachably connected to the pen core 32, which is convenient for replacing the bionic contact 34 according to test requirements and for maintaining the test pen 30. For example, when the bionic contact 34 is damaged, it can be replaced separately.

[0061] Among them, reference Figures 1 to 4 The test device further includes a pressure sensor 50, which is disposed between the first output terminal 21 and the test pen 30. For example, referring to Figure 2 and Fig. 9 , the pressure sensor 50 can be arranged between the first output end 21 and the outer shell 31 of the test pen 30. For another example, referring to Figure 7 The pressure sensor 50 can be disposed between the mounting bracket 22 (described in detail later) of the first rotating assembly 20 and the free end 11. The pressure sensor 50 can detect the magnitude of the pressure applied by the mechanical arm 10 to the display screen, thereby preventing the display screen from being damaged due to excessive pressure applied by the mechanical arm 10, and improving the fault tolerance and safety of the test process.

[0062] In an exemplary embodiment, Figure 1 As shown, the embodiment of the present disclosure provides a testing device, which is used to test the display function of an electronic device. The testing device includes a mechanical arm 10, a first rotating component 20 and a testing pen 30. The first rotating component 20 is arranged at the free end 11 of the mechanical arm 10. The first output end 21 of the first rotating component 20 is connected to the testing pen 30. The first output end 21 can rotate around a preset rotation axis. The axial direction of the first preset rotation axis 211 is parallel to the horizontal plane. The testing pen 30 includes an outer shell 31, a pen core 32 and a buffer 33. The outer shell 31 defines a receiving chamber 311. The pen core 32 and the buffer 33 are arranged in the receiving chamber 311.

[0063] The testing device provided in this embodiment may include various structures and components of the testing devices provided in the above-mentioned various embodiments.

[0064] In some embodiments, Figure 1 As shown, the test device also includes a second rotating component 40, which is disposed between the free end 11 of the mechanical arm 10 and the first rotating component 20. The second rotating component 40 has a second output end (not shown in the drawings), which is connected to the first rotating component 20. The second output end rotates around a second preset rotating axis, and the axial direction of the second preset rotating axis is parallel to the vertical direction. As can be seen from the above, the second rotating component 40 can drive the first rotating component 20 to rotate around the second preset rotating axis, thereby driving the test pen 30 to rotate around the second preset rotating axis, thereby changing the relative position of the test pen 30 and the display screen of the electronic device. In one example, refer to Figure 5 and Figure 6 The testing device is provided with a plurality of test pens 30 arranged in a line. The second rotating component 40 can make the arrangement direction of the plurality of test pens 30 parallel to the width direction of the electronic device, or can make the arrangement direction of the plurality of test pens 30 parallel to the length direction of the electronic device, thereby meeting different testing requirements and testing electronic devices with different operating logics.

[0065] In this embodiment, by providing the second rotating assembly 40 , the relative position of the test pen 30 and the display screen can be adjusted to meet the needs of various test scenarios.

[0066] Among them, Figures 2 to 4 As shown, the test pen 30 further includes a connecting portion 35, a first end of the connecting portion 35 is connected to the first output end 21 of the first rotating assembly 20, and a second end of the connecting portion 35 is connected to the outer shell 31 of the test pen 30. In one example, referring to Figure 2 , showing that the extending direction of the connecting portion 35 is parallel to the axial direction of the first output end 21. In another example, referring to Figure 8, showing that the extending direction of the connecting portion 35 is perpendicular to the axial direction of the first output end 21, and the extending direction of the connecting portion 35 is also perpendicular to the vertical direction.

[0067] It can be confirmed that by setting the connection part 35, the distance between the test pen 30 and the second preset rotation axis can be increased, so that the second rotating assembly 40 can quickly adjust the position of the test pen 30. In addition, the shape of the connection part 35 can be set according to actual needs, for example, Figure 4 , showing that the end of the connecting portion 35 away from the outer shell 31 has a flat mounting structure, so that the test pen 30 has a larger mounting area, improving the structural reliability, and also making the test pen 30 and the pressure sensor 50 have a larger contact area, avoiding excessive concentration of force on the pressure sensor 50, thereby extending the service life of the pressure sensor 50.

[0068] In some embodiments, Figure 4 As shown, the first rotating assembly 20 includes a mounting frame 22, a servo motor 23 and a coupling 24. The mounting frame 22 includes a first mounting structure 221 and a second mounting structure 222 and a third mounting structure 223 that are parallel to each other. One side of the first mounting structure 221 is connected to the free end 11. The second mounting structure 222 and the third mounting structure 223 are arranged on the side of the first mounting structure 221 that is away from the free end 11. The servo motor 23 is connected to the second mounting structure 222. The output shaft 231 of the servo motor 23 passes through the second mounting structure 222. The coupling 24 is arranged between the second mounting structure 222 and the third mounting structure 223. One side of the coupling 24 is connected to the output shaft 231. The other end of the coupling 24 is connected to the first output end 21. The first output end 21 of the first rotating assembly 20 is rotatably connected to the third mounting structure 223. In this embodiment, the first output end 21 and the servo motor 23 are separately arranged on the second mounting structure 222 and the third mounting structure 223 to prevent the force between the test pen 30 and the electronic device from being directly transmitted to the servo motor 23, reduce the axial load and radial load of the output shaft 231 of the servo motor 23, and help extend the service life of the servo motor 23. In addition, the servo motor 23 can be based on the MODBUS protocol control algorithm to accurately adjust the angle of the test pen 30 and record the angle.

[0069] In some embodiments, Figure 1As shown, the mechanical arm 10 of the test device includes a lifting assembly 12, and the lifting assembly 12 includes a lifting bracket 122 and a lifting slider 121. The lifting bracket 122 constitutes the fixed end of the mechanical arm 10, and a lifting guide rail 123 extending in the vertical direction is provided on the lifting bracket 122. The lifting slider 121 is connected to the lifting guide rail 123 and can move relative to the lifting bracket 122 along the extension direction of the lifting guide rail 123 to achieve lifting or lowering. In one example, the lifting guide rail 123 can be a lead screw, and the lifting slider 121 is threadedly matched with the lead screw. The rotation of the lead screw causes the lifting slider 121 to rise or fall. In another example, the lifting guide rail 123 can be a rack, and the lifting slider 121 is provided with a gear meshing with the rack. The rotation of the gear causes the lifting slider 121 to rise or fall.

[0070] Continue to refer Figure 1 The lifting assembly 12 further includes a horizontal moving assembly 13, which is disposed on a lifting slider 121 of the lifting assembly 12. The first end of the horizontal moving assembly 13 is connected to the lifting slider 121, and the second end constitutes the free end 11 of the mechanical arm 10, so that the horizontal moving assembly 13 can drive the second rotating assembly 40, the first rotating assembly 20 and the test pen 30 to move arbitrarily in the horizontal direction, for example, the test point position of the test pen 30 on the display screen can be adjusted, and the test pen 30 can be controlled to slide on the display screen.

[0071] In one example, reference Figure 1 , the horizontal moving assembly 13 includes a first connecting rod 131 and a second connecting rod 132 which are rotatably connected, an end of the first connecting rod 131 away from the second connecting rod 132 is rotatably connected to the lifting slider 121, and an end of the second connecting rod 132 away from the first connecting rod 131 constitutes the free end 11 of the robot arm 10. Through the relative rotation of the first connecting rod 131 and the second connecting rod 132, and the rotation of the first connecting rod 131 relative to the lifting slider 121, the free end 11 of the robot arm 10 can be moved arbitrarily in the horizontal direction. In another example (not shown in the drawings), the horizontal moving assembly 13 can be composed of a straight guide rail extending in the x direction and a straight guide rail extending in the y direction, so that the horizontal moving assembly 13 and the lifting assembly 12 constitute an xyz three-axis moving mechanism, which will not be described in detail in this disclosure.
