Detailed Description

In order to make the objects, technical solutions and advantages of the present application more clear, the present application will be further described in detail with reference to the accompanying drawings.

For convenience in understanding of the mobile terminal detection device provided in the embodiment of the present application, an application of the mobile terminal detection device is first described, and the mobile terminal detection device is applied to a screen test of a mobile terminal, and simulates a scene in which a screen is affected by an external force when the mobile terminal is used by applying forces in different directions. The mobile terminal can be a common mobile terminal such as a mobile phone and a tablet computer. When the screen is subjected to a horizontal force, the screen of the mobile terminal is damaged. As shown in fig. 1, the screen includes a first substrate 10 and a second substrate 20, and further includes a sub-pixel unit 30 disposed between the first substrate 10 and the second substrate 20, when the sub-pixel unit 30 is subjected to a horizontal external force, the sub-pixel unit 30 is squeezed, which may cause a display screen to have a red basket spot, resulting in a screen damage. Therefore, when the screen is detected, in order to detect the stress condition when the screen is damaged, the detection device needs to provide a horizontal external force to detect the screen. The following describes the mobile terminal detection device provided in the embodiments of the present application in detail with reference to the accompanying drawings.

As shown in fig. 2, fig. 2 is a schematic structural diagram of a mobile terminal detection device provided by an embodiment of the present application. The mobile terminal detection device provided in the embodiment of the application mainly comprises two structural parts, one is a supporting table for fixedly supporting the mobile terminal 6, and the other is a pressing device for providing a force.

First, as for the support table for supporting the mobile terminal 6, when the support table is specifically provided, different structures may be adopted to support the mobile terminal 6. As in a particular embodiment, with reference to the structure shown in fig. 2, the support platform includes a lift platform 4, and a support frame 13 for supporting the mobile terminal 6. The lifting platform 4 can lift along the vertical direction, and the specific structure of the lifting platform can comprise a hydraulic cylinder or an air cylinder and a supporting plate connected with a piston rod of the hydraulic cylinder or the air cylinder, and of course, other structures capable of achieving lifting can be adopted to achieve the lifting function, such as a gear rack assembly or a screw rod assembly.

The support 13 of the support platform can rotate relative to the lifting platform 4 when being arranged. The support frame 13 is disposed on top of the lifting platform 4 and can rotate relative to the lifting platform 4. When the support frame 13 is specifically realized to rotate relative to the lifting platform 4, the rotation can be realized in different manners, as shown in fig. 2, the support frame can further include a rotating device 5, and the rotating device 5 is fixedly arranged on the lifting platform 4 and can drive the support frame 13 to rotate. When specifically setting up rotary device 5, this rotary device 5 can be a motor, and the output shaft and the support frame 13 fixed connection of this motor, when the output shaft of motor rotated, the motor drove support frame 13 and rotates. Or the rotating device 5 may further include a motor and a speed reducer connected to the motor, and an output shaft of the speed reducer is fixedly connected to the supporting frame 13. Of course, besides the above-mentioned rotating device 5, the rotating device 5 can also be used to rotate the supporting frame 13 in other ways.

Except for the mode that the support frame 13 is not directly connected with the lifting platform 4, the rotation of the support frame 13 relative to the lifting platform 4 can be realized by adopting the mode that one end of the support frame 13 is rotatably connected with the lifting platform 4. When the driving support frame 13 rotates, the rotation is realized through the arranged hydraulic cylinder or the air cylinder, at the moment, the cylinder body of the hydraulic cylinder or the air cylinder is hinged with the lifting platform 4, the piston rod of the air cylinder or the hydraulic cylinder is hinged with the support frame 13, and when the piston rod extends out or retracts back, the driving support frame 13 rotates relative to the lifting platform 4.

It should be understood that no matter which connection method is adopted, when the supporting frame 13 rotates relative to the lifting platform 4, the angle of the mobile terminal 6 supported by the supporting frame 13 can be adjusted. Of course, the above-mentioned only some specific embodiments that can achieve the adjustment of the angle and the height of the mobile terminal 6 can be applied to the embodiments of the present application, and any other solutions that can achieve the adjustment of the angle and the height of the mobile terminal 6 can also be applied to the embodiments of the present application.

In addition, for the convenience of moving the supporting platform, the detection equipment is provided with a slide rail 2, and a lifting platform 4 of the supporting platform is slidably assembled on the slide rail 2 and can be locked at a set position.

When the mobile terminal 6 is placed on the support frame 13 for detection, the pressing device presses the screen of the mobile terminal 6, and the pressing force applied by the pressing device is transmitted to the support frame 13. In order to be able to simulate the compression in different scenarios, a base 12 is detachably connected to the support 13 when the support is set up, the base 12 being located below the mobile terminal 6 and supporting the mobile terminal 6. As shown in fig. 6, fig. 6 shows a specific embodiment, in the structure shown in fig. 6, the supporting frame 13 includes a circular supporting plate 131, and four supporting legs 132 disposed around the supporting plate 131; each supporting leg 132 is provided with an accommodating groove, the substrate 12 is directly placed in the accommodating groove, or some clamping grooves are formed in the supporting frame 13, and the substrate 12 is directly clamped on the supporting frame 13. However, in any of the above manners, it should be ensured that the back surface of the mobile terminal 6 completely falls onto the substrate 12 when the mobile terminal 6 is fixed on the support 13, so as to ensure that a scene when the mobile terminal 6 is placed on different materials can be truly simulated during detection. In addition, fig. 6 illustrates only one specific embodiment of the structure of the supporting frame 13, and other embodiments may be adopted. And, for the above substrate 12, it can be made of different materials, for example, the substrate 12 can be a soft cushion, marble, wood, steel platform, etc. The base 12 made of different materials simulates the mobile terminal 6 to be in different scenes so as to ensure the accuracy in detection.

For the supporting table structure provided in the embodiment of the present application, in addition to the above-mentioned structure, other structural forms may also be adopted, for example, the supporting table is only a solid table body, and specifically, different structures such as a circular table and a square table may be adopted. The mobile terminal 6 may be directly placed on a support table for fixing when in use, but when such a structure is adopted, the substrate 12 may be provided to simulate different scenes.

After the mobile terminal 6 is fixed on the support table, a pressing device needs to be adopted to press the screen of the mobile terminal 6 to simulate a scene that the screen is pressed. The pressing device, when set, comprises a first driving device 8 and a pressing head 11, wherein the pressing head 11 is used for pressing the screen of the detected mobile terminal 6. And the first drive means 8 is arranged to bring the ram 11 to press against the screen. In particular implementation, as shown in fig. 2, fig. 2 shows one particular implementation of the hold-down device. The first drive means 8 is arranged on a support 1, the support 1 is of an inverted L-shaped construction, the first drive means 8 is arranged on a cross beam of the support 1 and the first drive means 8 can effect a movement in the vertical direction. If the first driving device 8 is a hydraulic cylinder or an air cylinder, the piston rod of the hydraulic cylinder or the air cylinder can drive the pressing head 11 to press downwards.

With continued reference to fig. 2, the stand 1 is coupled to a position adjustment device for adjusting the position of the first drive means 8 so as to bring the ram 11 to press against different locations on the screen. The position adjustment means may be of different construction. As in a particular embodiment, the position adjustment device comprises a first slide rail fixedly connected to the cross beam of the support 1, and a second slide rail slidably mounted on the first slide rail, and the first drive device 8 slidably mounted on the second slide rail. The length direction of the first slide rail is perpendicular to the length direction of the second slide rail, so that the first driving device 8 can be adjusted to different positions on a horizontal plane. Of course, besides the above-mentioned first slide rail and second slide rail, the first linear motor and the second linear motor may also be adopted. At this time, the first linear motor is fixedly connected with the bracket 1, the second linear motor is connected with the first linear motor, and the first driving device 8 is connected with the second linear motor, so that the effect of adjusting the first driving device 8 in the upward direction of the horizontal plane can be achieved. In addition to the two specific solutions listed above, the position adjustment device provided in the embodiment of the present application may also adopt other solutions to adjust the position of the first driving device 8.

Besides the above-mentioned combination of the support 1 and the position adjusting device to adjust the position of the first driving device 8, other configurations may be adopted, such as a mechanical arm to support the first driving device 8, and the position of the first driving device 8 may be adjusted by the movement of the mechanical arm. Alternatively, as a variant, the first driving means 8 is fixed and the support table is moved to adjust the position of the mobile terminal 6, in which case the support table is slidably mounted on a slide rail similar to the above-described structure comprising the first slide rail and the second slide rail, so as to adjust the relative position of the mobile terminal 6 and the first driving means 8. Of course, other ways may also be used, such as the way that the first driving device 8 and the supporting platform can both slide, in which case the first driving device 8 slides along the first direction, the supporting platform slides along the second direction, and the first direction and the second direction are both in the horizontal plane and perpendicular to each other.

When the first driving device 8 drives the pressure head 11 to be pressed down, an angle adjusting device is adopted. The angle adjusting device is respectively connected with the first driving device 8 and the pressure head 11 in a rotating way and is used for adjusting the direction of the force applied to the pressure head 11 by the first driving device 8. When the angle adjusting device is connected to the first drive device 8, it is in particular rotatably connected to a connecting base connected to the piston rod of the hydraulic or pneumatic cylinder. The angle adjustment means, when specifically arranged, is used to adjust the angle of the ram 11 relative to the first drive means 8. As shown in fig. 2, the angle adjusting device includes a push rod 10, one end of the push rod 10 is rotatably connected to the first driving device 8, specifically, to the connecting seat in the first driving device 8, and the other end of the push rod 10 is rotatably connected to the pressing head 11. Therefore, when the push rod 10 rotates, the pressing head 11 is driven to rotate relative to the first driving device 8, so that more pressing heads 11 are adjusted relative to the first driving device 8. In use, the first driving device 8 can only provide a vertically downward force, and the force applied by the first driving device 8 is transmitted to the third pressing head 11 through the push rod 10, and since the push rod 10 is a straight rod, the direction of the force provided by the push rod extends along the length direction of the straight rod. When the pressure head 11 is applied to the screen, the pressure head 11 is pressed against the screen, and because the push rod 10 and the screen form a certain included angle, the force applied to the pressure head 11 is also a certain inclination angle, that is, the vertical force provided by the first driving device 8 is changed into a component force having a horizontal direction and a vertical direction by the arranged angle adjusting device, so that the force applied to the screen in a real scene can be simulated more accurately. As shown in fig. 3 and 4, fig. 3 and 4 respectively show the force of the pressing head acting on the screen when the push rod 10 is at different angles, as shown by the straight line with an arrow in fig. 3. Referring first to fig. 3, in the structure shown in fig. 3, the push rod 10 is vertically disposed, and at this time, the force generated by the pressing head to the screen is a vertical force. Whereas in fig. 4 the angle between the push rod 10 and the vertical is α, the force applied by the first drive means 8 is F, and the direction of F is along the push rod 10, the vertical component F1, which is included in the force applied by the ram 11 to the screen, is Fsin α, and the horizontal component F2 is Fcos α. Of course, the rotating means 5 can also be used together when the tilting of the push rod 10 with respect to the screen is realized. As shown in fig. 5, the support bracket 13 is rotated by the rotating means 5 so that the mobile terminal 6 is tilted, and at the same time, the push rod 10 is also tilted with respect to the vertical plane so that the ram can generate more horizontal component force in the force applied to the mobile terminal.

When the push rod 10 is rotated, the rotation is achieved through a second driving device of the angle adjusting device, and the second driving device is used for driving the push rod 10 to rotate relative to the first driving device 8, so that the pressure head 11 is driven to rotate. When the second driving device is specifically configured, different structures can be adopted, for example, in a specific embodiment, the second driving device is a stepping motor fixedly disposed on the first driving device 8, and an output shaft of the stepping motor is fixedly connected with the push rod 10. When the second driving device is specifically provided, the second driving device is provided on the connecting seat of the first driving device 8, and the push rod 10 is rotatably connected with the first driving device 8 through the stepping motor. In addition, the second driving device may also adopt other modes such as driving a reduction gearbox by a driving motor, or driving a rack by an air cylinder or a hydraulic cylinder, driving a gear to rotate by the rack, fixedly connecting the gear with the push rod 10, and the like. The effect of driving the push rod 10 to rotate can be achieved.

When the pressing head 11 is pressed against the screen, the pressing head 11 has a pressing surface which is in contact with the screen. When the pressing head 11 is rotatably connected with the angle adjusting device, the pressing surface of the pressing head 11 cannot be ensured to face the screen all the time. In order to ensure that the pressing surface of the pressing head 11 always faces the screen and the pressing surface of the pressing head 11 still faces the screen when the push rod 10 rotates, a pressing head 11 adjusting assembly is arranged, and the pressing head 11 adjusting assembly is used for synchronously 3 and reversely rotating the pressing head 11 when the push rod 10 rotates so as to ensure that the pressing surface of the pressing head 11 always faces the screen. When specifically setting up this pressure head 11 adjustment assembly, its structure that contains is: a first belt pulley 9 and a synchronous belt 3 sleeved on the first belt pulley 9. And two ends of the synchronous belt 3 are respectively fixedly connected with the pressure head 11; wherein, the first belt wheel 9 is rotationally connected with the first driving device 8; and the device also comprises a third driving device for driving the first belt wheel 9 to rotate. Referring to the structure shown in fig. 2, it can be seen from fig. 2 that when the adjustment assembly of the ram 11 is provided, the first pulley 9 is rotatably connected to the second driving device, but the first pulley 9 may be rotatably connected to the push rod 10. However, in either case, the axis of the first pulley 9 intersects the axis of the push rod 10. Further, when the timing belt 3 is provided, as shown in fig. 2, positions where both ends of the timing belt 3 are connected to the ram 11 are arranged on both sides of the push rod 10. When the screen pressing device is used, after the second driving device drives the push rod 10 to rotate for a certain angle, the third driving device drives the first belt pulley 9 to rotate in the opposite direction (opposite to the rotating direction of the push rod 10), at the moment, the synchronous belt 3 drives the pressing head 11 to rotate in the opposite direction for the same angle, so that the condition that the pressing surface of the push rod 10 inclines after rotating is offset, and the pressing surface can always keep the effect of facing the screen. If the push rod 10 rotates by 10 degrees, the pressure head 11 assembly drives the pressure head 11 to rotate by-10 degrees, and in short, the rotating angle of the push rod 10 is always equal to the rotating angle of the pressure head 11 and the rotating directions are opposite.

Of course, when the adjustment assembly of the pressing head 11 is provided, other modes may be adopted, such as a first belt pulley 9 and a second belt pulley, at this time, the first belt pulley 9 is rotatably connected with the push rod 10 or the second driving device, the second belt pulley is fixedly connected with the pressing head 11, and the synchronous belt 3 is sleeved on the first belt pulley 9 and the second belt pulley, so as to drive the pressing head 11 to rotate in the same manner.

In the detection using the above-described device, the direction of the pressing force is adjusted by adjusting the push rod 10, and the direction of the pressing force may also be changed by the direction of the screen of the mobile terminal 6. For example, the mobile terminal 6 is moved downwards by the lifting platform 4, then the mobile terminal 6 is rotated by the rotating device 5 to be adjusted to a required angle, and then the mobile terminal is lifted to an original position by the lifting platform 4. After the mobile terminal 6 is adjusted, the rotating angle of the push rod 10 is adjusted, and meanwhile, the pressing surface on the pressing head 11 is adjusted to be parallel to the screen through the pressing head 11 adjusting assembly. The ram 11 is then depressed by the first drive means 8 so that the effect of forces in different directions on the screen can be simulated. After the force is applied, the image of the pressed sub-pixels on the screen is captured by the image capturing device 7, and the image capturing device 7 may be a microscope. When the microscope is specifically set up, it is also connected to the stand 1 or the robot arm. In use, the indenter 11 is removed and the microscope is moved to the squeezed position on the screen for photographing.

For the convenience of understanding the mobile terminal 6 detection device provided in the embodiment of the present application, the following describes in detail a flow of detecting the mobile terminal 6 by taking the structure shown in fig. 2 as an example. First, as shown in fig. 2, the mobile terminal 6 is fixed on a support 13, and a substrate 12 such as marble is provided on the support 13. After placing mobile terminal 6 to basement 12, rotate through rotary device 5 in order to adjust the angle of mobile terminal 6, and adjust the height of mobile terminal 6 through lift platform 4, make mobile terminal 6 be located the below of pressure head 11, afterwards, adjust the angle of pressure head 11 through angle adjusting device, after adjusting the angle, control first drive arrangement 8 and drive pressure head 11 and push down, make pressure head 11 support and press on mobile terminal 6, and exert pressure through first drive arrangement 8 for pressure head 11, in order to extrude the screen of mobile terminal 6. Reference may be made to FIG. 4; when the force provided to the ram 11 by the first driving device 8 is F, a horizontal pressing force F1 is generated to press the pixels of the screen through F1. After the simulation extrusion is completed, the pressure head 11 is driven to ascend through the first driving device 8, the pressure head 11 is moved away through the arranged position adjusting device, the camera device 7 is moved to the position where the pressure head 11 is extruded before shooting, whether the basket spot 61 appears or not is judged according to the shot picture, and when the condition as shown in fig. 7 appears, the basket spot 61 appears.

As can be seen from the above description, the mobile terminal detection device provided in the embodiment of the present application can adjust the direction of the force applied by the pressure head 11 to the screen according to the detection requirement, so that the effect of pressing the screen in different environments can be simulated. And further, the detection accuracy can be improved.

The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present application, and shall be covered by the scope of the present application.
