Detailed Description

The terminology used in the description of the embodiments of the application herein is for the purpose of describing particular embodiments of the application only and is not intended to be limiting of the application.

The optical characteristic test board for the display screen provided by the embodiment of the application can test the optical characteristic of the display screen of the electronic equipment. The electronic device may be, but is not limited to, a mobile phone, a tablet computer, a notebook computer, a netbook, etc.

In the field of display screen optical characteristic testing, an automatic display screen optical characteristic testing machine is a common testing tool. The automatic display screen optical characteristic testing machine can be provided with various testing instruments, simulate manual testing modes, match testing requirements of different testing instruments, and automatically adjust the relative positions between the tested display screen and the testing instruments so as to achieve the purpose of testing the optical characteristics of the display screen.

Fig. 1 shows a structure of a related art display screen optical characteristic test machine. Referring to fig. 1, the display screen optical property testing machine includes a chassis 10 and an optical property testing instrument 20 provided on the chassis 10. The frame 10 is provided with a vertical lifting mechanism 30, and a mounting plate 40 is arranged on the vertical lifting mechanism 30. The electronic device 50 may be connected to the mounting board 40, that is, the electronic device is connected to the vertical lifting mechanism 30 through the mounting board 40, and the electronic device 50 is driven to move up and down in a vertical direction (for example, to reciprocate in a Z direction as shown in fig. 1) by the vertical lifting mechanism 30.

Wherein the display screen 51 of the electronic device 50 is opposite to the optical property testing instrument 20, and the optical property testing instrument 20 is kept stationary during the vertical movement of the electronic device 50, so that the optical property of the display screen 51 of the electronic device 50 is tested by the optical property testing instrument 20.

If the display screen 51 of the electronic device 50 has a longer length in the X direction shown in fig. 1, the test range of the optical property test instrument 20 is exceeded. At this time, the position of the optical property testing device 20 is adjusted so that the optical property testing device 20 is moved horizontally (for example, reciprocated in the X direction shown in fig. 1). The optical characteristics of the entire display screen 51 are tested by the electronic device 50 moving up and down in the vertical direction and the whole optical characteristics testing instrument 20 moving left and right in the horizontal direction.

Further, the test distances of the different optical property test instruments 20 are different. That is, the different optical property testing instruments 20 have different distance requirements from the display screen 51 when testing the optical properties of the display screen 51. Accordingly, the optical property testing instrument 20 may be moved toward or away from the electronic device 50 (e.g., reciprocally moved in the Y-direction as shown in fig. 1), thereby adjusting the distance between the optical property testing instrument 20 and the electronic device 50.

However, the optical characteristics of the display screen 51 of the electronic device 50 are tested by moving the electronic device 50 and moving the optical characteristic testing apparatus 20. It is necessary that both the electronic device 50 and the optical property testing device 20 are provided with a structure capable of driving movement thereof, and the optical property test of the display screen 51 is performed in conjunction with the movement of both the electronic device 50 and the optical property testing device 20. That is, the electronic device 50 and the optical property testing apparatus 20 are required to be adjusted at the same time, and at the same time, due to the existence of an adjustment error, it is required to eliminate an overlapping error when both move, or both are provided with corresponding error compensation, etc. Thus, the test operation is complex, and the test efficiency is low.

Based on the above, the embodiment of the application provides an optical characteristic test board for a display screen, which drives a test instrument or a supporting unit arranged on a first driving mechanism through the first driving mechanism to perform transverse movement, longitudinal movement and vertical movement, thereby completing the test of the optical characteristic of the display screen of the whole electronic equipment by the test instrument. When the testing instrument tests the optical characteristics of the display screen, the testing instrument and the supporting unit do not need to be coordinated and move simultaneously, and only the movement error of one of the testing instrument and the supporting unit needs to be eliminated, so that the variable is convenient to control, the operation is more convenient and quick, and the testing efficiency is improved.

The application is described below with reference to the drawings and specific embodiments.

Fig. 2 is a schematic structural diagram of an optical property testing machine for a display screen according to an embodiment of the present application; fig. 3 shows a schematic structural diagram of an optical property testing machine for a display screen with another view angle.

Referring to fig. 2 and 3, the optical property testing machine for a display screen provided in an embodiment of the present application includes a base 100, a supporting unit 200, a driving unit 300 and a testing apparatus 400, where the driving unit 300 includes a first driving mechanism 310, the first driving mechanism 310 is disposed on the base 100, the testing apparatus 400 has a testing end surface 410, and the supporting unit 200 is used for supporting the display screen 51 of the electronic device 50 so that the display screen 51 of the electronic device 50 faces the testing end surface 410.

In the present application, the base 100 is used to support the support unit 200, the first driving mechanism 310 and the test instrument 400, and the upper surface 110 of the base 100 provides an installation space for the first driving mechanism 310 and the support unit 200 disposed on the upper surface 110 of the base 100 or the test instrument 400 disposed on the upper surface 110 of the base 100.

In particular, the base 100 may be a frame-type support. The base 100 may also be a support platform. The base 100 may have a storage cavity inside, and the side surface of the base 100 may be further provided with an openable door 120, so that the storage cavity is exposed or closed by opening and closing the door 120.

In some embodiments, the bottom of the base 100 may have leveling foot pads 130, and the number of leveling foot pads 130 may be at least three. The leveling foot pad 130 is used to adjust the height of the base 100 at different positions to maintain the base 100 stationary on uneven supporting surfaces (e.g., the ground) and prevent the base 100 from rocking. Thereby providing stable support for the support unit 200, the first driving mechanism 310 and the test instrument 400. Wherein the leveling foot pad 130 may also be referred to as a leveling foot. The leveling foot pad 130 is constructed and arranged in a manner similar to that of the leveling foot at the bottom of the machine tool.

In the present application, there is no limitation on the number of leveling footpads 130. In particular implementations, the number of leveling footpads 130 may be set according to the size of the base 100, with the number of leveling footpads 130 increasing the greater the size of the base 100. The leveling footpads 130 are uniformly spaced at the bottom of the base 100 and each leveling footpad 130 may be adjacent to a side of the base 100, thereby facilitating adjustment of the leveling footpads 130.

In another embodiment, the bottom of the base 100 may further be provided with rollers 140, and the number of the rollers 140 may be at least three. At least one of the rollers 140 may be a universal wheel. By providing the roller 140, it is thus convenient to move the optical property test machine of the display screen. When the optical property testing machine of the display screen needs to be placed in the testing area, the base 100 of the optical property testing machine of the display screen is pushed, and the roller 140 rolls on the ground to place the optical property testing machine in the testing area. When the leveling foot pad 130 is installed, the height of the base 100 is adjusted, so that the roller 140 at the bottom of the base 100 is separated from the ground, and the optical property testing machine of the display screen is prevented from being separated from the testing area in use.

It should be noted that, the portions of the leveling foot pads 130 and the rollers 140 contacting the ground are made of antistatic materials, such as rubber materials.

In the present application, the test instrument 400 is used to test the optical characteristics of the display 51 of the electronic device 50. The test instrument 400 may be one, two or more, thereby meeting different test requirements.

While the test instrument 400 tests the optical characteristics of the display screen 51 of the electronic device 50, one of the support unit 200 and the test instrument 400 may remain stationary, and the other may move. Hereinafter, these two modes will be described.

In one possible implementation, the support unit 200 is disposed on the first driving mechanism 310 and the test instrument 400 is disposed on the base 100. The test instrument 400 remains stationary and the first driving mechanism 310 drives the support unit 200 provided on the first driving mechanism 310 to move. The first driving mechanism 310 drives the supporting unit 200 to move in a movement plane, and the first driving mechanism 310 can also drive the supporting unit 200 to move relative to the test instrument 400 so as to adjust the distance between the supporting unit 200 and the test instrument 400; wherein the plane of motion is parallel to the test end face 410.

The movement plane may be an XZ plane shown in fig. 2, and the first driving mechanism 310 drives the support unit 200 to move in the XZ plane shown in fig. 2. Illustratively, the first driving mechanism 310 drives the supporting unit 200 to move left and right (e.g., reciprocate in the X direction shown in fig. 2), and the first driving mechanism 310 drives the supporting unit 200 to move up and down (e.g., reciprocate in the Z direction shown in fig. 2). The first driving mechanism 310 may also drive the supporting unit 200 to move back and forth (e.g., reciprocate along the Y direction shown in fig. 2), so that the supporting unit 200 approaches or moves away from the test instrument 400, so as to adjust the distance between the supporting unit 200 and the test instrument 400, so as to meet the requirements of different types of test instruments 400 on the test distance between the display screen 51 and the test instrument 400.

It will be appreciated that the side-to-side movement may also be referred to as lateral movement, the back-and-forth movement may also be referred to as longitudinal movement, and the up-and-down movement may be referred to as vertical movement.

Fig. 4 shows another structure of the optical property test station of the display screen. Referring to fig. 4, the movement plane may also be the XY plane shown in fig. 4, and the first driving mechanism 310 drives the supporting unit 200 to move in the XY plane shown in fig. 4. Illustratively, the first driving mechanism 310 drives the supporting unit 200 to move left and right (e.g., reciprocate in the X direction shown in fig. 4), and the first driving mechanism 310 drives the supporting unit 200 to move back and forth (e.g., reciprocate in the Y direction shown in fig. 4). The first driving mechanism 310 may also drive the supporting unit 200 to move up and down (e.g., reciprocate along the Z direction shown in fig. 4), so that the supporting unit 200 approaches or moves away from the test instrument 400, so as to adjust the distance between the supporting unit 200 and the test instrument 400, so as to meet the requirements of different types of test instruments 400 on the test distance between the display screen 51 and the test instrument 400.

In the embodiment, if the types of the test instruments 400 are large (for example, the types of the test instruments 400 are two or more), or the weight of the test instruments 400 is heavy, the test instruments 400 may be kept still, and the first driving mechanism 310 may drive the supporting unit 200 provided on the first driving mechanism 310 to move.

In another possible implementation, the test instrument 400 is disposed on the first driving mechanism 310 and the support unit 200 is disposed on the base 100. The support unit 200 remains stationary and the first driving mechanism 310 drives the movement of the test instrument 400 provided on the first driving mechanism 310. The first driving mechanism 310 drives the test instrument 400 to move in a movement plane, and the first driving mechanism 310 can also drive the test instrument 400 to move relative to the support unit 200 so as to adjust the distance between the support unit 200 and the test instrument 400; wherein the plane of motion is parallel to the test end face 410.

Wherein the support unit 200 remains stationary and the first driving mechanism 310 drives the movement of the test instrument 400 provided on the first driving mechanism 310. Similar to the embodiment of fig. 2 and 4 described above in which the test instrument 400 remains stationary, the first drive mechanism 310 drives the support unit 200 provided on the first drive mechanism 310. That is, the support unit 200 and the test instrument 400 are interchanged, and the rest of the structures and the movement modes are the same, and reference may be made to the description of the embodiment of fig. 2 and fig. 4, which is not repeated here.

In particular, if the types of the test instruments 400 are less than or equal to two types and the test instruments 400 have a relatively light weight, the above embodiment may be adopted in which the support unit 200 is kept still and the first driving mechanism 310 drives the test instruments 400 disposed on the first driving mechanism 310 to move.

In the present application, the test instrument 400 or the supporting unit 200 provided on the first driving mechanism 310 is driven by the first driving mechanism 310 to perform lateral movement, longitudinal movement and vertical movement, thereby completing the test of the optical characteristics of the test instrument 400 on the display screen 51 of the entire electronic device 50. When the test instrument 400 tests the optical characteristics of the display screen 51, the test instrument 400 and the supporting unit 200 do not need to move simultaneously in coordination with each other, and only the movement error of one of the test instrument 400 and the supporting unit 200 needs to be eliminated, so that the variable is convenient to control, the operation is more convenient and quick, and the test efficiency is improved.

The first driving mechanism 310 drives the supporting unit 200 to move, and the test instrument 400 is kept still; and the first driving mechanism 310 drives the test instrument 400 to move, the two different ways in which the support unit 200 remains stationary are described. Next, a possible implementation of the first driving mechanism 310 will be described.

In one possible implementation, the drive unit may be a robotic arm. The first drive mechanism 310 is part of a robotic arm. One of the supporting unit 200 and the testing instrument 400 is mounted on a mechanical arm, and the operation is convenient by driving the one of the supporting unit 200 and the testing instrument 400 to move through the mechanical arm.

In another possible implementation, the first drive mechanism 310 may be a tri-axial linear module. One of the support unit 200 and the test instrument 400 is mounted on a triaxial linear module, and one of the support unit 200 and the test instrument 400 is driven to move by the triaxial linear module. Such as the triaxial linear module driving support unit 200 shown in fig. 2, to move. The triaxial linear module is low in cost, long in service life and high in precision.

In a specific implementation, the three axes in the three-axis linear module may be coordinate axes perpendicular to each other in three pairs, i.e., the X axis, the Y axis, and the Z axis in fig. 2. Wherein the support unit 200 is installed on the Z-axis. Wherein the height on the Z axis can be 1630 mm-1650 mm, the effective stroke on the Z axis can be 440 mm-460 mm, the effective stroke on the Y axis can be 1240 mm-1260 mm, and the effective stroke on the X axis can be 300 mm-320 mm.

The above test method adopts a positive viewing angle, that is, the optical characteristics of the display screen 51 are tested in a scenario where the test instrument 400 is facing the display screen 51 of the electronic device 50. But in use of the electronic device 50, the display 51 of the electronic device 50 may be angled from the user's viewing angle. The optical characteristics of the display screen 51, such as the luminance and color degradation performance at different viewing angles of the user, are also important indicators for evaluating the optical characteristics of the display screen 51.

In the present application, the driving unit 300 further includes a second driving mechanism 320, the supporting unit 200 or the test instrument 400 disposed on the first driving mechanism 310 is connected to the first driving mechanism 310 through the second driving mechanism 320, and the second driving mechanism 320 is used for driving the supporting unit 200 or the test instrument 400 to rotate relative to the first driving mechanism 310 to adjust the incident angle r of the display screen 51; the second driving mechanism 320 is further used for driving the supporting unit 200 or the test instrument 400 to rotate in the movement plane so as to adjust the azimuth angle f of the display screen 51.

Fig. 5 shows the azimuthal position. Referring to fig. 2 and 5, in some embodiments, the support unit 200 is disposed on the first driving mechanism 310, and the support unit 200 is connected to the first driving mechanism 310 through the second driving mechanism 320. The second driving mechanism 320 may drive the supporting unit 200 to rotate in the XZ plane with the Y axis as a rotation axis in fig. 2. Thereby, the azimuth angle f of the display screen 51 of the electronic device 50 mounted on the supporting unit 200 is adjusted. The azimuth angle f is an angle between the azimuth line f ₂ of the display screen 51 and the horizontal line f ₁ of the horizontal plane. Fig. 5 shows the initial position and the rotated position of the display screen 51, respectively, and the position of the display screen 51 shown by the solid line box in fig. 5 is the initial position, where the horizontal line f ₁ of the horizontal plane coincides with the azimuth line f ₂ of the display screen 51. The position of the display screen 51 shown by the broken line box in fig. 5 is a position where the display screen 51 is rotated by a certain angle in the XZ plane.

The present application is not limited to the angle at which electronic device 50 rotates in the XZ plane. Wherein the azimuth angle f is between +180° and-180 °, and the azimuth angle f may be between 0 ° and 360 °.

Fig. 6 shows the location of incidence. Referring to fig. 2 and 6, the second driving mechanism 320 may also drive the supporting unit 200 to rotate with respect to the first driving mechanism 310 to adjust an incident angle r of the display screen 51 of the electronic device 50 mounted on the supporting unit 200. That is, the second driving mechanism 320 drives the supporting unit 200 to rotate in the XY plane with the Z axis as a rotation axis in fig. 2, so that the supporting unit 200 is out of the movement plane. The incident angle r is an included angle between the display screen normal f ₄ and the test end surface normal f ₃. Fig. 6 shows the initial position and the rotated position of the display screen 51, respectively, and the position of the display screen 51 shown by the solid line box in fig. 6 is the initial position, where the display screen normal f ₄ and the test end surface normal f ₃ coincide. The position of the display screen 51 shown by the broken line box in fig. 6 is a position after the display screen 51 is rotated by a certain angle in the XY plane.

In the present application, the angle of incidence r may be adjusted between +75° and-75 °. Illustratively, when the display screen 51 is in the position shown by the dashed box in FIG. 6, the angle of incidence r is 0, the display screen 51 may be rotated 75 clockwise in the XY plane of FIG. 2, and the display screen 51 may also be rotated 75 counterclockwise, thereby effecting an adjustment of the angle of incidence r between +75 and-75.

It should be noted that, in another embodiment, the test apparatus 400 is disposed on the first driving mechanism 310. The difference between this embodiment and the above-mentioned supporting unit 200 disposed on the first driving mechanism 310 is that the positions of the testing apparatus 400 and the supporting unit 200 are interchanged, and the rest of the structures are the same, and the manner in which the second driving mechanism 320 drives the testing apparatus 400 through the first driving mechanism 310 is not described herein again.

In the application, by arranging the second driving mechanism 320, the second driving mechanism 320 drives one of the supporting unit 200 and the testing instrument 400 to rotate relative to the other, so that the azimuth angle f and the incidence angle r between the two are adjusted, the omnidirectional visual angle test of the display screen 51 is satisfied, and the integration level of the optical characteristic testing machine of the display screen is improved.

The structure of the second driving mechanism 320 will be described below.

Fig. 7 shows the structures of the driving unit 300 and the supporting unit 200, and fig. 8 shows the structure of the second driving mechanism 320 in the driving unit 300. Referring to fig. 2 to 8, in the present application, the second driving mechanism 320 includes a first driving assembly 321 and a first supporting seat 322, the first supporting seat 322 is connected with the first driving mechanism 310, and the first driving assembly 321 is disposed on the first supporting seat 322.

The first driving assembly 321 drives the supporting unit 200 to rotate with respect to the first driving mechanism 310. As shown in fig. 7, the first support base 322 is connected to the Z axis of the first driving mechanism 310, and the first support base 322 is driven to move up and down along the Z axis of the first driving mechanism 310 by the first driving mechanism 310. The first driving assembly 321 drives the supporting unit 200 to rotate in the XY plane with the Z axis as a rotation axis with respect to the first driving mechanism 310, and an incident angle between the display screen 51 and the test end surface 410 is measured. Alternatively, as shown in fig. 4, the first driving unit 321 drives the test instrument 400 to rotate in a movement plane (for example, in an XZ plane) with respect to the first driving mechanism 310, with the Y axis as a rotation axis.

Specifically, the first reduction member 3212 may be a gear reduction box or a belt reduction assembly or the like for reduction. The first driving piece 3211 may be a rotary motor, a rotary hydraulic cylinder, or a rotary air cylinder. The first driving member 3211 is decelerated by the first deceleration member 3212, so that the first rotation member 3213 precisely adjusts the rotation angle of the support unit 200 or the test instrument 400.

The first driver 3211 is also connected to an encoder. An encoder is a device that compiles, converts, or communicates, transmits, and stores signals or data into a signal form. The position coordinates of the supporting unit 200 or the test instrument 400 are recorded by the encoder, so that the loss of the existing position coordinates in the case of sudden power failure or the like is avoided. Wherein the encoder may be an absolute encoder. The absolute encoder is encoded by mechanical position determination, and has higher anti-interference characteristic and higher reliability of data.

The first reduction gear 3212, the first driving member 3211 and the first reduction gear 3212 may be connected with the first supporting seat 322 by a detachable connection manner such as a screw, a clamping connection, etc., and the first reduction gear 3212, the first driving member 3211 and the first reduction gear 3212 may also be fixedly connected with the first supporting seat 322 by a manner such as welding, bonding, etc. Wherein the first rotating member 3213 may be a rotating platform.

In the present application, the first driving assembly 321 is connected to the second supporting seat 324 of the second driving assembly 323 through the second supporting seat 324, so that the first driving assembly 321 drives the second driving assembly 323 and the second supporting seat 324 to integrally rotate, thereby adjusting the azimuth angle.

As shown in fig. 4, the second driving unit 323 drives the test instrument 400 to rotate in a movement plane (for example, XY plane) with the Z axis as a rotation axis.

Referring to fig. 8 to 10, in a specific implementation, the second support base 324 and the first support base 322 may have the same structure, and the second support base 324 may be stacked on the first support base 322.

Specifically, the second support base 324 may include a third support 3241 and a fourth support 3242 disposed at one side of the third support 3241, the fourth support 3242 being parallel to the first support 3221. The third support 3241 is parallel to the second support 3222, the first driving assembly 321 is located between the third support 3241 and the second support 3222, and the third support 3241 is connected to the first rotation member 3213. The fourth support 3242 is located between the first support 3221 and the second drive assembly 323. Thus, the rotation axis S ₁ of the second rotating member 3231 and the rotation axis S ₂ of the first rotating member 3213 are perpendicular, and the structure of the second driving mechanism 320 is compact.

With continued reference to fig. 10, the second driving assembly 323 further includes a second driving member 3232 and a second speed reducing member 3233, wherein the second rotating member 3231, the second driving member 3232 and the second speed reducing member 3233 are all connected to the second supporting seat 324, and the second driving member 3232 and the second rotating member 3231 are connected through the second speed reducing member 3233.

The second driving element 3232 may have the same structure as the first driving element 3211, the second decelerating element 3233 may have the same structure as the first decelerating element 3212, and the second rotating element 3231 may have the same structure as the first rotating element 3213. The connection manner and the working principle of the second driving member 3232, the second decelerating member 3233 and the second rotating member 3231 are the same as those of the first driving member 3211, the first decelerating member 3212 and the first rotating member 3213, and the description thereof will be referred to and will not be repeated here.

Fig. 11 shows another second drive mechanism 320, and fig. 12 and 13 show the structure of the slip assembly 325 from different angles, respectively. Referring to fig. 7, 8, and 11 to 13, in order to increase the adjustment accuracy, in some embodiments, the second driving mechanism 320 further includes a slide assembly 325, the slide assembly 325 is disposed on the second rotating member 3231, the support unit 200 or the test instrument 400 is detachably disposed on the slide assembly 325, and the slide assembly 325 is used to drive the support unit 200 or the test instrument 400 to move toward at least one direction in a movement plane.

The sliding table assembly 325 may be an electric sliding table, and fine adjustment is performed on the supporting unit 200 or the testing instrument 400 through the electric sliding table. The adjustment direction of the electric sliding table may be at least one of the Z-axis direction and the X-axis direction in fig. 2 or 7. Or the adjustment direction of the electric slipway may be at least one of the Y-axis direction and the X-axis direction in fig. 4. In specific implementation, the adaptability can be selected according to the test requirements.

In the present application, the origin of coordinates of XYZ axes of the driving unit 300 may be disposed at a central position of the supporting unit 200. Illustratively, as shown in fig. 2, the slipway assembly 325 may fine tune the center point position of the display screen 51 such that the center point position of the display screen 51 coincides with the center position of the support unit 200. In this way, it is possible to facilitate acquisition of the displacement value of the display screen 51.

Referring to fig. 8, 11, 14 and 15, in order to facilitate mounting the slide assembly 325 on the second rotating member 3231, in some embodiments, the second driving mechanism 320 further includes a first transfer plate 326, the slide assembly 325 is connected to the second rotating member 3231 through the first transfer plate 326, and the second rotating member 3231 drives the slide assembly 325 and the first transfer plate 326 to rotate. When the size of the second rotating member 3231 is smaller than that of the sliding table assembly 325, the installation space of the sliding table assembly 325 is increased by the first intermediate rotating plate 326, so that the sliding table assembly 325 and the second rotating member 3231 are firmly installed.

When the weight of the test instrument 400 is greater than the weight of the electronic device 50, or when the number of the test instruments 400 is large (for example, two or more). Since the weight of the electronic device 50 on the supporting unit 200 is relatively light with respect to the test instrument 400, the electronic device 50 is easily installed. The support unit 200 may be provided on the first driving mechanism 310 as shown in fig. 2 or 7. In this way, the first driving mechanism 310 is facilitated to drive the supporting unit 200.

To facilitate mounting of the electronic device 50 on the support unit 200, the movement plane is a vertical plane, and the first driving mechanism 310 includes a vertical driving assembly (e.g., a driving assembly in the Z-axis direction in fig. 2 or 7), on which the support unit 200 is disposed.

Next, the structure of the supporting unit 200 will be described.

Fig. 16 shows the structures of the second driving mechanism 320 and the supporting unit 200, and fig. 17 and 18 show the structures of the supporting unit 200 and the second transfer plate 250 from different angles, respectively. Referring to fig. 7, 16 to 19, in some embodiments, the support unit 200 includes a support plate 210 and a clamping mechanism including a clamp assembly 220, the clamp assembly 220 being detachably connected to the second driving mechanism 320 through the support plate 210, the clamp assembly 220 being used to clamp the electronic device 50. The present application clamps the electronic device 50 by the clamp assembly 220, thus facilitating rapid disassembly and assembly of the electronic device 50, thereby improving work efficiency.

In particular implementations, the support plate 210 and the ramp assembly 325 of the second drive mechanism 320 are removably coupled. Wherein, the support plate 210 and the sliding table assembly 325 can be connected by a detachable connection mode such as clamping connection or screw connection. Alternatively, the second transfer plate 250 may be provided on one of the slide table assembly 325 or the support plate 210, the slide table assembly 325 being fixed to the second transfer plate 250, and the support plate 210 being detachably connected to the second transfer plate 250. The effect of the second transfer plate 250 is the same as that of the first transfer plate 326.

For example, the support plate 210 may have at least one first mounting hole 211 thereon, and the second transfer plate 250 may have at least one second mounting hole 251 thereon, the first mounting hole 211 and the second mounting hole 251 being disposed in one-to-one correspondence, and screws being installed in the first mounting hole 211 and the second mounting hole 251 to detachably connect the support plate 210 and the second transfer plate 250, thereby detaching the clamp assembly 220 from the slide assembly 325. Wherein the number of the first mounting holes 211 and the second mounting holes 251 may be two or more, thereby increasing the stability of the connection of the clamp assembly 220 and the slide table assembly 325.

According to the application, the support plate 210 and the second driving mechanism 320 are detachably connected, so that the support units 200 with different sizes can be replaced, and thus, the electronic equipment 50 with different sizes can be tested, and the phenomenon of unstable support of the support unit 200 when the size of the support unit 200 is smaller than that of the electronic equipment 50 is avoided. For example, the mobile phone, the tablet computer, the notebook computer, and the netbook may correspond to the support unit 200 having a size that matches or is slightly larger than the size thereof, respectively.

To facilitate positioning of the support plate 210 with the second transfer plate 250, in some embodiments, two first positioning pins 252 are provided on one of the second transfer plate 250 and the support plate 210, and two first positioning holes 212 are provided on the other. The first positioning pins 252 are inserted into the corresponding first positioning holes 212 to position the support plates 210 such that the clamp assembly 220 can hold the electronic device 50 in the same state, for example, the electronic device 50 is kept in a vertical state or a horizontal state, when the support units 200 of different sizes are connected to the slide assembly 325.

It is understood that when the second mounting hole 251 is not provided, the second mounting hole 251 may be provided on the slide assembly 325, and the first positioning hole 212 or the first positioning pin 252 may be provided on the slide assembly 325. That is, the sliding table assembly 325 is mounted and positioned with the support plate 210 in the same manner as the second transfer plate 250 is mounted and positioned with the support plate 210 in the above-described embodiment.

In the present application, the supporting unit 200 may be provided with a plurality of sets to meet the test requirements of the optical characteristics of the display screen 51 within 4 to 15 inches.

Fig. 20 shows the structure of the clamp assembly 220. As shown in fig. 7, 16, 17 and 20, the clamp assembly 220 includes two clamping members 221, the two clamping members 221 being disposed opposite to each other, and the two clamping members 221 clamping or unclamping the electronic device 50. The two opposite clamping members 22 are respectively contacted with two opposite sides of the electronic device 50 to clamp the electronic device 50, so that the clamping is stable.

Wherein the two clamping members 221 may be oppositely disposed in the X-axis direction in fig. 16, thereby forming a vertical clamping state. It is also possible to arrange oppositely in the Z-axis direction in 14 so as to form a horizontal gripping state, that is, two gripping members 221 in fig. 16 are rotated by 90 ° in the XZ plane. In a specific implementation, the two clamping members 221 may be symmetrically arranged.

Fig. 21 shows the structure of the holder 221. Referring to fig. 7, 16, 20 and 21, the clamping member 221 includes a support portion 2211 and at least one clamping finger 2212 provided on the support portion 2211, the support portion 2211 being in contact with the back surface of the electronic device 50, the clamping finger 2212 being used to clamp the electronic device 50. Wherein the back surface of the electronic device 50 is opposite to the display screen 51, the supporting portions 2211 of the two holding members 221 are located in the same plane (for example, in a vertical plane), and the electronic device 50 is supported by the supporting portions 2211, so that the electronic device 50 is vertically placed on the holding members 221, and the state that the display screen 51 is opposite to the test end surface 410 is maintained. Errors in the placement of the electronic device 50 are avoided from causing measurement errors in the test instrument 400.

In a specific implementation, the number of the holding fingers 2212 may be two or more, and the number of the holding fingers 2212 on the two holding members 221 may be the same or different. The clamping fingers 2212 on the two clamping pieces 221 can be staggered or opposite to each other. The application is not limited in this regard.

The clamping finger 2212 may abut against a side surface of the electronic device 50, and the clamping finger 2212 may further extend to the surface of the display screen 51 and abut against the surface of the display screen 51. That is, the gripping finger 2212 may have an L-shape.

In particular implementations, the sides of the support 2211 can have at least one groove 2211a with the gripping fingers 2212 partially embedded in the groove 2211a and removably attached to the groove 2211 a. By changing the gripping finger 2212 to a different size, a different thickness of the electronic device 50 is used. The electronic device 50 held by the holding finger 2212 is placed in an upright state by manually adjusting the mounting angle of the holding finger 2212.

In some embodiments, the contact surface 2211b of the support portion 2211 and the electronic device 50 is a rough surface. In this way, the support portion 2211 and the back surface of the electronic device 50 can be prevented from being attracted to each other, and thus the corresponding electronic device 50 and the support portion 2211 can be quickly disengaged.

In a specific implementation, the contact surface 2211b may be a sandblasted surface, for example, the contact surface 2211b is subjected to a 100-mesh sandblasting treatment.

With continued reference to fig. 20 and 21, the clamp assembly 220 further includes at least one first elastic member 222, and the two clamping members 221 are connected by the first elastic member 222. When the two clamping members 221 clamp the electronic device 50, the elastic force of the first elastic member 222 keeps the clamping members 221 clamping the electronic device 50.

The electronic device 50 is inserted between the two clamping members 221, the two clamping members 221 are separated from each other, the first elastic member 222 is extended to increase the distance between the two clamping members 221, the two clamping members 221 form a space for accommodating the electronic device 50, and the elastic force of the first elastic member 222 keeps the clamping members 221 clamping the electronic device 50. When the electronic device 50 needs to be removed, the first elastic member 222 urges the two clamping members 221 toward each other. In this way, a single-handed quick replacement of the electronic device 50 may be achieved.

Wherein the first elastic member 222 may be a spring or a bungee cord. The number of the first elastic members 222 may be two or more, and the first elastic members 222 are uniformly spaced, so that the force applied to the clamping member 221 is relatively uniform.

In order to facilitate the installation of the first elastic member 222, the opposite sides of the support portion 2211 of the two clamping members 221 may be provided with mounting posts 2211c, and both ends of the first elastic member 222 are respectively connected to the mounting posts 2211c of the two clamping members 221.
