Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of electronic device testing, and in particular to a testing device and a testing system. BACKGROUND

[0002] With the increasing demand for electronic devices (such as mobile phones, tablets, smart watches, etc.) year by year, electronic devices have more and more functions. Some functions of electronic devices need to be tested before leaving the factory to verify whether the functions meet the corresponding requirements. For example, electronic devices generally have a photography function, and the implementation of the function is based on a camera module. Electronic devices need to be tested before leaving the factory, that is, each electronic device needs to be photographed at the same test point for the same area to verify whether the photographing quality of the electronic device meets the requirements.

[0003] However, in the existing testing process, the electronic devices are generally manually sent to the test point for testing, which can easily cause poor spatial position consistency of multiple electronic devices, that is, the actual positions of the electronic devices and the test point have large deviations, and it is difficult to analyze and compare the test results of the electronic devices. CONTENT OF THE UTILITY MODEL

[0004] Embodiments of the present application provide a testing device and a testing system to solve the problem of poor spatial position consistency of multiple electronic devices in the existing testing process.

[0005] To achieve the above purpose, embodiments of the present application adopt the following technical solutions:

[0006] In a first aspect, the embodiments of the present application provide a testing device for testing electronic devices, which comprises a driving mechanism, a base and a plurality of clamping mechanisms. The plurality of clamping mechanisms are fixed to the base, and the driving mechanism is connected to the base. The driving mechanism is used to drive the base to move so that any one of the plurality of clamping mechanisms stays at a test point.

[0007] The testing device provided by the first aspect of the present application sets a plurality of clamping mechanisms on the base, and drives the base to move by the driving mechanism to make any one of the plurality of clamping mechanisms stay at a test point. In this way, when a plurality of electronic devices are clamped on the corresponding clamping mechanisms for testing, the spatial position consistency of the plurality of electronic devices during testing can be greatly improved, that is, the actual positions of the electronic devices and the test point have small deviations, which is conducive to reducing the difficulty of subsequent analysis and comparison of test results.

[0008] With reference to the first aspect, in a possible implementation manner, the base has a first axis, the plurality of clamping mechanisms are arranged at intervals around the first axis, and the driving mechanism is configured to drive the base to rotate around the first axis. In this way, by driving the base to rotate around the first axis by the driving mechanism, any clamping mechanism on the base and the corresponding electronic device can be transported to the test point for testing.

[0009] With reference to the first aspect, in another possible implementation manner, the plurality of clamping mechanisms are arranged in a circular array around the first axis. That is, the central angle β corresponding to the line connecting any two adjacent clamping mechanisms and the first axis is equal, and the distance between each clamping mechanism and the first axis is also equal. In this way, during testing, the current position of any clamping mechanism on the base and the corresponding electronic device can be specified as the test point, and then the driving mechanism only needs to drive the base to rotate by a specified angle β each time, so that the other adjacent clamping mechanism and the corresponding electronic device can accurately enter the test point for testing, and the testing of the plurality of electronic devices can be completed in turn. The above structure is beneficial to reducing the control difficulty of the driving mechanism, for example, a stepping motor or a servo motor can be used.

[0010] With reference to the first aspect, in another possible implementation manner, the plurality of clamping mechanisms are arranged at intervals along a first straight line, and the driving mechanism is configured to drive the base to move along the first straight line. In this way, by driving the base to move along the first straight line by the driving mechanism, any clamping mechanism on the base and the corresponding electronic device can be transported to the test point for testing.

[0011] With reference to the first aspect, in another possible implementation manner, the plurality of clamping mechanisms are arranged at equal intervals along the first straight line. In this way, during testing, the current position of any clamping mechanism on the base and the corresponding electronic device can be specified as the test point, and then the driving mechanism only needs to drive the base to move along the first straight line by a preset distance d (d is equal to the interval between the center points of any two adjacent clamping mechanisms) each time, so that the other adjacent clamping mechanism and the corresponding electronic device can accurately enter the test point for testing, and the testing of the plurality of electronic devices can be completed in turn. The above structure is beneficial to reducing the control difficulty of the driving mechanism, for example, a stepping motor or a servo motor can be used.

[0012] With reference to the first aspect, in another possible implementation manner, the clamping mechanism comprises a back plate and a clamping piece. The back plate is fixed to the base, and the back plate has a first surface facing away from the base. The clamping piece is arranged on the back plate and protrudes from the first surface. In this way, the clamping piece and the first surface form a clamping space, and the electronic device can be clamped and fixed on the clamping piece.

[0013] With reference to the first aspect, in a possible implementation manner, the clamping member comprises a first clamping portion and a second clamping portion. The first surface of the back plate has opposite first and second edges, and the first clamping portion is arranged at the first edge and the second clamping portion is arranged at the second edge. In this way, the first clamping portion, the second clamping portion and the first surface jointly form a clamping space, and the electronic device is clamped and fixed between the first clamping portion and the second clamping portion after being placed in the clamping space.

[0014] With reference to the first aspect, in a possible implementation manner, the clamping mechanism further comprises an adjusting assembly arranged on the back plate, and at least one of the first clamping portion and the second clamping portion is connected with the adjusting assembly. The adjusting assembly is configured to adjust the distance between the first clamping portion and the second clamping portion. In this way, the volume of the clamping space can be increased by moving the first clamping portion and the second clamping portion away from each other through the adjusting assembly, so as to facilitate the electronic device to be placed into the clamping mechanism. After the electronic device is placed into the clamping mechanism, the electronic device can be clamped and fixed between the first clamping portion and the second clamping portion by moving the first clamping portion and the second clamping portion closer to each other through the adjusting assembly. In addition, the distance between the first clamping portion and the second clamping portion can be adjusted through the adjusting assembly, so that the clamping mechanism can be adapted to electronic devices of different sizes, thereby improving the versatility of the clamping mechanism.

[0015] With reference to the first aspect, in a possible implementation manner, the adjusting assembly comprises an adjusting knob and a screw rod. A screw hole is arranged on the side wall surface of the back plate, and a through hole is arranged on the first clamping portion or the second clamping portion. One end of the screw rod is fixedly connected with the adjusting knob after passing through the through hole, and the other end of the screw rod is screwed into the screw hole. In this way, the screw rod can be rotated by rotating the adjusting knob clockwise or counterclockwise, and the distance between the first clamping portion and the second clamping portion can be adjusted by changing the screwing amount of the screw rod in the screw hole. That is, the size of the clamping space can be adjusted by rotating the screw rod, so as to facilitate the electronic device of different sizes to be placed into the clamping mechanism. After the electronic device is placed into the clamping mechanism, the electronic device can be clamped and fixed between the first clamping portion and the second clamping portion by screwing the screw rod.

[0016] In another possible implementation manner, the adjusting assembly comprises a pull rod and a spring, the side wall surface of the back plate is provided with a blind hole, the spring is fixed to the bottom of the blind hole, one end of the pull rod is fixedly connected with the first clamping part or the second clamping part, and the other end of the pull rod extends into the blind hole and is connected with the spring. In this way, a pulling force can be applied to the first clamping part or the second clamping part, the pulling force is transmitted to the spring through the pull rod, the spring is stretched and deformed, and then the spacing between the first clamping part and the second clamping part is changed. That is, the size of the clamping space can be adjusted by pulling the first clamping part or the second clamping part, so that electronic devices of different sizes can be conveniently placed into the clamping mechanism. After the electronic device is placed into the clamping mechanism, the pulling force applied to the first clamping part or the second clamping part is removed, and the first clamping part or the second clamping part is driven to move close to each other by the elastic force of the spring, until the opposite two side edges of the electronic device are respectively abutted against the first clamping part and the second clamping part. That is, the electronic device can be automatically clamped by the above structure.

[0017] With reference to the first aspect, in another possible implementation manner, a first limiting groove is arranged on the surface of the first clamping part facing the second clamping part, and a second limiting groove is arranged on the surface of the second clamping part facing the first clamping part. In this way, when the electronic device is clamped on the clamping mechanism, the opposite two side edges of the electronic device can be correspondingly embedded into the first limiting groove and the second limiting groove, so that the risk of the electronic device being detached from the clamping mechanism can be reduced.

[0018] With reference to the first aspect, in another possible implementation manner, the first limiting groove penetrates through the first clamping part along the extension direction of the first clamping part, and the second limiting groove penetrates through the second clamping part along the extension direction of the second clamping part. In some cases, when the length of the electronic device is greater than the length of the first clamping part and the length of the second clamping part, the edges of the electronic device cannot be embedded into the first limiting groove and the second limiting groove. Therefore, by designing the first limiting groove and the second limiting groove as through grooves, the above situation can be avoided.

[0019] With reference to the first aspect, in another possible implementation manner, the clamping mechanism further comprises a positioning member, the first surface of the back plate has a third edge connected between the first edge and the second edge, and the positioning member is fixed to the third edge and protrudes from the first surface. For the convenience of description, an XYZ coordinate system is established, the length direction of the back plate is taken as the X-axis direction, the width direction of the back plate is taken as the Y-axis direction, and the thickness direction of the back plate is taken as the Z-axis direction. In this way, when the electronic device is clamped, the positioning member, the first clamping part, the second clamping part and the back plate can be combined to realize accurate positioning of the electronic device. That is, the back plate can limit the movement of the electronic device in the Z-axis direction, the first clamping part and the second clamping part can limit the movement of the electronic device in the Y-axis direction, and the positioning member can limit the movement of the electronic device in the X-axis direction.

[0020] With reference to the first aspect, in a possible implementation manner, the clamping mechanism further comprises at least one guide rod, the guide rod is fixed on the back plate, and a guide hole is arranged on the first clamping part or the second clamping part, and the guide rod is arranged in the guide hole. Alternatively, the guide rod is fixed on the first clamping part or the second clamping part, and a guide hole is arranged on the side wall surface of the back plate, and the guide rod is arranged in the guide hole. In this way, when the first clamping part or the second clamping part is moved by the adjusting assembly, the guide rod can guide the first clamping part or the second clamping part to prevent the first clamping part or the second clamping part from being deflected during movement.

[0021] With reference to the first aspect, in a possible implementation manner, a plurality of guide rods are arranged, a plurality of guide holes are arranged, the plurality of guide rods correspond to the plurality of guide holes in one-to-one correspondence, and the plurality of guide rods are arranged at intervals. In this way, the plurality of guide rods arranged at intervals can make the first clamping part or the second clamping part move more smoothly, and can also reduce the risk of the first clamping part or the second clamping part being deflected when clamping the electronic device.

[0022] With reference to the first aspect, in a possible implementation manner, the back plate is provided with an avoiding opening, and the avoiding opening penetrates the back plate along the thickness direction of the back plate. In this way, by arranging the avoiding opening, the back plate can avoid blocking the view angle of the camera module of the electronic device, that is, the clamping mechanism is completely outside the view angle of the camera module. In addition, since the camera decoration cover of the electronic device generally protrudes from the back cover, the avoiding opening can avoid the camera decoration cover of the electronic device, that is, the camera decoration cover can extend into the avoiding opening, so that the back cover of the electronic device can be attached to the back plate, thereby ensuring the stability of the clamped electronic device.

[0023] With reference to the first aspect, in a possible implementation manner, the base comprises a bottom plate and a plurality of support arms. The plurality of support arms are arranged at intervals around the central axis of the bottom plate, and the plurality of support arms correspond to the plurality of clamping mechanisms in one-to-one correspondence. One end of the support arm is fixedly assembled with the bottom plate, and the other end of the support arm is fixedly assembled with the clamping mechanism. The driving mechanism comprises a driving body and an output shaft, the output shaft is rotationally connected with the driving body, the bottom plate is fixedly assembled with the output shaft, and the axis of the output shaft coincides with the central axis of the bottom plate.

[0024] In this way, the base and the output shaft of the driving mechanism are quickly connected by assembling and fixing the bottom plate and the output shaft, that is, multiple bases can be equipped during testing, each base clamping a group of electronic devices, and after a group of electronic devices is tested, the base can be quickly connected to another base for testing another group of electronic devices, thereby improving the testing efficiency. In addition, the above structure also realizes the modular design of the base and the clamping mechanism. When testing two groups of electronic devices with large size difference (for example, one group of electronic devices is a mobile phone and the other group of electronic devices is a tablet computer), the clamping mechanism with corresponding size and the support arm with corresponding length can be replaced to make the structure of the base and the clamping mechanism more compact and lighter under the premise that the adjacent electronic devices do not interfere with each other, thereby reducing the load of the driving mechanism.

[0025] In combination with the first aspect, in another possible implementation manner, the driving mechanism is a six-axis articulated robot. The base is connected to the end joint of the six-axis articulated robot. The six-axis articulated robot has six degrees of freedom, and the electronic devices on the clamping mechanism can reach any point in the working radius space of the robot by driving the six-axis articulated robot.

[0026] In combination with the first aspect, in another possible implementation manner, the testing device further includes a mobile platform, and the driving mechanism is arranged on the mobile platform. During photographing testing, different scenes need to be photographed, such as restaurant scene models, office scene models, bar scene models, and the like. In this way, by arranging the driving mechanism on the mobile platform, the mobile platform can move the driving mechanism, the base, the multiple clamping mechanisms, and the multiple electronic devices between different scenes, thereby improving the testing efficiency. In addition, during testing, the mobile platform moves the driving mechanism, the base, the multiple clamping mechanisms, and the multiple electronic devices to a scene first, and then moves to the next scene after the multiple electronic devices in the group test the same area in the scene, so as to ensure the consistency of the multiple electronic devices for the same scene.

[0027] In the second aspect, the application provides a testing system, which includes the testing device provided in the first aspect and a central control module. The central control module is in communication connection with the electronic devices, and is configured to analyze and compare the test results of the electronic devices.

[0028] It can be understood that the testing system provided in the second aspect and any possible implementation manner thereof has the beneficial effects as described in the first aspect and any possible implementation manner thereof, which will not be described herein again.

DETAILED DESCRIPTION

[0049] In order to make the purpose, technical scheme and advantages of the application clearer, the application will be further described in detail below with embodiments. It should be understood that the specific embodiments described herein are only used to explain the application and not to limit the application.

[0050] In the description of the present application, it should be clear that the terms "vertical", "transverse", "longitudinal", "front", "back", "left", "right", "up", "down", "horizontal" and the like indicate the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present application, and does not mean that the device or element referred to must have a particular orientation or position, and therefore cannot be understood as a limitation on the present application. The "number" cannot be understood as a limitation on the present application.

[0051] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting" should be understood in a broad sense, for example, can be fixedly connected, or can be detachably connected, or integrally connected; can be mechanically connected, or can be electrically connected; can be directly connected, or can be indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0052] With the increasing demand for the use of electronic devices year by year, the electronic devices have more functions. Specifically, the electronic device can be a portable electronic device or other types of electronic devices. For example, the electronic device can be a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a monitor, a camera, a personal computer, a notebook computer, a wearable device, etc. For the convenience of explanation, the following examples are taken as a mobile phone as an example.

[0053] Please refer to Figure 1 and Figure 2 , Figure 1 the overall structure schematic diagram of the electronic device 02 provided by the embodiment of the present application, Figure 2 the structure explosion diagram of the electronic device 02 in the above Figure 1 It can be known from the above that in the present embodiment, the electronic device 02 is a mobile phone, and the electronic device 02 can have an approximately rectangular plate structure. The electronic device 02 can include a display module 2a, a frame 2b, a camera module 2c, a back cover 2d, and a camera decoration cover 2e.

[0054] It can be understood that Figure 1 and Figure 2 only some components included in the electronic device 02 are schematically shown, and the actual shape, actual size, actual position and actual structure of these components are not limited by Figure 1 and Figure 2 .

[0055] The display module 2a is used to display images, videos, etc. The display module 2a and the back cover 2d are respectively fixed on both sides of the frame 2b, so that the display module 2a, the frame 2b and the back cover 2d enclose a containing cavity inside the electronic device 02, and the camera module 2c and other components of the electronic device 02 are arranged in the containing cavity.

[0056] The aforementioned camera module 2c is used to capture video or images and can achieve autofocus (AF), thus making it suitable for various shooting scenarios. The camera decorative cover 2e protrudes from the back cover 2d; the camera decorative cover 2e is used to decorate the camera module 2c and also to prevent the camera module 2c from being scratched by external objects. The aforementioned camera module 2c and camera decorative cover 2e can be configured as follows... Figure 1 The camera module 2c and camera decorative cover 2e are positioned near one edge of the back cover 2d. Alternatively, the camera module 2c and camera decorative cover 2e can be located in the upper middle part of the back cover 2d. Figure 1 (Not shown in the image). Therefore, this application does not impose any special restrictions on the specific location of the camera module 2c.

[0057] Before leaving the factory, the aforementioned electronic devices 02 need to undergo some functional tests to verify whether each function meets the corresponding requirements. For example, before leaving the factory, mobile phones need to undergo a photo-taking test on the camera module 2c. That is, each mobile phone needs to take a picture of the same area at the same test point to compare and verify whether the photo quality of the mobile phone meets the requirements.

[0058] However, existing testing devices 01 generally involve single-machine testing and manual replacement during the testing process. This means that only one electronic device 02 can be manually delivered to the test point for testing at a time. This can easily lead to poor spatial consistency of multiple electronic devices 02 when taking pictures. In other words, there is a large deviation between the actual shooting position of the electronic device 02 and the test point, and the deviation is also different for each electronic device 02. Since the viewing angle α of the camera module 2c of each electronic device 02 being tested is the same, this results in a large deviation in the imaging area of ​​each electronic device 02, making it difficult to analyze and compare the shooting results of each electronic device 02.

[0059] For example, see Figure 3 As shown, Figure 3 This diagram illustrates the actual positional deviation of two electronic devices 02 during image capture. The two electronic devices 02 are designated as first electronic device 02a and second electronic device 02b. During image capture, the actual position of first electronic device 02a is used as the test point, and the actual position of second electronic device 02b... Figure 3 The deviation between the actual position of the dashed box and the actual position (i.e., the test point) of the first electronic device 02a is L. After the object to be photographed is photographed, the deviation between the imaging area S2 of the second electronic device 02b and the imaging area S1 of the first electronic device 02a is also L. It is difficult to analyze and compare the shooting results of the first electronic device 02a and the second electronic device 02b.

[0060] To address the aforementioned technical problems, this application provides a testing device 01, please refer to [link to relevant documentation]. Figure 4 and Figure 5 As shown,Figure 4 A structural schematic diagram of a test device 01 provided by an embodiment of the present application, Figure 5 Clamping multiple electronic devices 02 Figure 4 A schematic diagram of multiple clamping mechanisms 12 in the middle.

[0061] The test device 01 comprises a driving mechanism 20, a base 11, and multiple clamping mechanisms 12 fixed to the base 11, wherein the clamping mechanism 12 is provided with a clamping space 100 suitable for accommodating the electronic device 02. The driving mechanism 20 is connected with the base 11, and the driving mechanism 20 is used to drive the base 11 to move, so that any one of the multiple clamping mechanisms 12 stays at a test point.

[0062] In this way, when multiple electronic devices 02 are clamped on the corresponding clamping mechanism 12 for testing, compared with artificial one-by-one conveying test, the above-mentioned test device 01 can greatly improve the consistency of the spatial position of the multiple electronic devices 02 during testing, that is, the deviation between the actual position of each electronic device 02 and the test point is small, thereby facilitating the reduction of the analysis and comparison difficulty of the subsequent test results.

[0063] In some embodiments, please continue to refer to Figure 4 and Figure 5 It is shown that the base 11 has a first axis 11a, and the multiple clamping mechanisms 12 are arranged at intervals around the first axis 11a, and the driving mechanism 20 is used to drive the base 11 to rotate around the first axis 11a. In this way, by driving the base 11 to rotate around the first axis 11a by the driving mechanism 20, any clamping mechanism 12 and the corresponding electronic device 02 on the base 11 can be conveyed to the test point for testing.

[0064] It can be understood that when the base 11 is a regular central symmetric structure, the central axis of the base 11 can be used as the first axis 11a, thereby facilitating the dynamic balance of the base 11 during rotation.

[0065] Specifically, the multiple clamping mechanisms 12 can be distributed in a circumferential array around the first axis 11a. That is, the central angle corresponding to the line connecting the center points of two adjacent clamping mechanisms 12 and the first axis 11a of the base 11 is the same, and the distance between the center point of each clamping mechanism 12 and the first axis 11a of the base 11 is also the same.

[0066] For example, please continue to refer to Figure 4 and Figure 5 It is shown that Figure 4 four clamping mechanisms 12 are provided on the base 11, and the four clamping mechanisms 12 are distributed in a circumferential array around the first axis 11a of the base 11, at this time, the central angle corresponding to the line connecting the center points of two adjacent clamping mechanisms 12 and the first axis 11a of the base 11 is the same, and the distance between the center point of each clamping mechanism 12 and the first axis 11a of the base 11 is also the same.Figure 5 The central angle β corresponding to the line connecting the black dots in the middle is 90°. Therefore, during testing, the current position of any clamping mechanism 12 on the base 11 and the corresponding electronic device 02 can be designated as the test point, for example, using... Figure 5 The position of the clamping mechanism 12 at the top of the base 11 in the indicated orientation is the test point. Then, each time, the driving mechanism 20 drives the base 11 to rotate 90° clockwise, so that the adjacent clamping mechanism 12 on the left and the corresponding electronic device 02 can accurately enter the test point for shooting (or, each time, the driving mechanism 20 drives the base 11 to rotate 90° counterclockwise, so that the adjacent clamping mechanism 12 on the right and the corresponding electronic device 02 can accurately enter the test point for testing). This process can be repeated to complete the test of a group of four electronic devices 02.

[0067] Similarly, the base 11 can also be equipped with three clamping mechanisms 12 (the central angle β corresponding to the line connecting the center point of two adjacent clamping mechanisms 12 to the first axis 11a of the base 11 is 120°), six clamping mechanisms 12 (the central angle β corresponding to the line connecting the center point of two adjacent clamping mechanisms 12 to the first axis 11a of the base 11 is 60°), eight clamping mechanisms 12 (the central angle β corresponding to the line connecting the center point of two adjacent clamping mechanisms 12 to the first axis 11a of the base 11 is 45°), etc., which will not be listed here.

[0068] Please see Figure 6 As shown, Figure 6 For clamping Figure 4 A comparison image of the imaging areas of the four electronic devices 02 on the test apparatus 01. From... Figure 6 As can be seen, the imaging areas of the four electronic devices 02 are highly consistent. In other words, the above-mentioned structural design of this application can greatly improve the consistency of the spatial position of multiple electronic devices 02 during testing. That is, the actual positions of each electronic device 02 are less different from each other, which helps to reduce the difficulty of subsequent analysis and comparison of test results.

[0069] In some embodiments, please refer back to the previous section. Figure 4 and combined Figure 7 As shown, Figure 7 This is a schematic diagram illustrating the combination of a base 11 and a clamping mechanism 12 according to an embodiment of this application. The base 11 may include a base plate 111 and multiple support arms 113. The multiple support arms 113 are spaced apart around the central axis of the base plate 111, which is the first axis 11a of the base 11. Each of the multiple support arms 113 corresponds to one of the multiple clamping mechanisms 12. One end of each support arm 113 is fixedly mounted to the base plate 111, and the other end of each support arm 113 is fixedly mounted to one of the clamping mechanisms 12.

[0070] Correspondingly, the driving mechanism 20 can include a driving body 21 and an output shaft 22, the output shaft 22 is rotationally connected with the driving body 21, the bottom plate 111 is fixedly assembled with the output shaft 22, and the axis of the output shaft 22 coincides with the first axis 11a of the base 11.

[0071] It can be understood that the above-mentioned fixed assembly can be a clamping (for example, transition fit, interference fit), threaded connection (for example, an inner thread and an outer thread are respectively arranged on the bottom plate 111 and the output shaft 22 to match each other), and the like, which is a connection assembly mode relying on the matching relationship between the structures of two components. The fixed assembly can also be a connection assembly mode in which two components are connected together through an additional connecting piece (for example, a bolt, a screw, a rivet, etc.).

[0072] In this way, the fixed assembly of the bottom plate 111 and the output shaft 22 facilitates the quick docking of the base 11 and the output shaft 22 of the driving mechanism 20, that is, a plurality of bases 11 can be provided during testing, each base 11 clamps a group of electronic devices 02, and after a group of electronic devices 02 are tested, another base 11 can be quickly docked for testing another group of electronic devices 02, thereby facilitating the improvement of testing efficiency. In addition, the above-mentioned structure also realizes the modular design of the base 11 and the clamping mechanism 12. When testing two groups of electronic devices 02 with large size difference (for example, one group of electronic devices 02 is a mobile phone and the other group of electronic devices 02 is a tablet computer), the clamping mechanism 12 with different sizes and the support arm 113 with different lengths can be replaced to make the structure of the base 11 and the clamping mechanism 12 more compact and lighter under the premise of ensuring that the adjacent electronic devices 02 do not interfere with each other, thereby facilitating the reduction of the load of the driving mechanism 20.

[0073] It can be understood that the above-mentioned driving mechanism 20 can be a servo motor, a stepper motor, a multi-axis mechanical arm, etc., which is not specially limited in the present application.

[0074] For example, the above-mentioned Figure 4 The driving mechanism 20 is a six-axis articulated mechanical arm, and the end joint of the six-axis articulated mechanical arm can serve as the output shaft 22. The bottom plate 111 of the base 11 is connected with the end joint of the six-axis articulated mechanical arm. The six-axis articulated mechanical arm has six degrees of freedom, and through the driving of the six-axis articulated mechanical arm, the electronic devices 02 on the clamping mechanism 12 can reach any point in the mechanical arm operation radius space.

[0075] In some embodiments, please continue to refer to Figure 7 , and in combination with Figure 8 , as shown in Figure 8A structural schematic diagram of a clamping mechanism 12 provided by an embodiment of the present application. The clamping mechanism 12 can include a back plate 121 and a clamping piece 120. The back plate 121 is fixed to the support arm 113, and the back plate 121 has a first surface 1210 facing away from the support arm 113, and the clamping piece 120 protrudes from the first surface 1210.

[0076] For the convenience of the following description, an XYZ coordinate system is established, in which the length direction of the back plate 121 of one of the clamping mechanisms 12 is the X-axis direction, the width direction of the back plate 121 is the Y-axis direction, and the thickness direction of the back plate 121 is the Z-axis direction.

[0077] Specifically, the clamping piece 120 can include a first clamping portion 122 and a second clamping portion 123. The first surface 1210 of the back plate 121 has opposite first and second edges 1211 and 1212, which are distributed along the Y-axis direction, and the first clamping portion 122 is arranged at the first edge 1211 and the second clamping portion 123 is arranged at the second edge 1212.

[0078] In this way, the first clamping portion 122, the second clamping portion 123 and the first surface 1210 together form a clamping space 100, and the electronic device 02 placed in the clamping space 100 is clamped and fixed between the first clamping portion 122 and the second clamping portion 123, and remains in contact with the first surface 1210.

[0079] Further, please continue to refer to Figure 8 As shown, the clamping mechanism 12 can also include an adjusting assembly 124. The adjusting assembly 124 is arranged on the back plate 121, and the adjusting assembly 124 is used to adjust the distance between the first clamping portion 122 and the second clamping portion 123 along the Y-axis direction.

[0080] It should be noted that the above-mentioned adjusting assembly 124 can be connected only with the first clamping portion 122, or only with the second clamping portion 123, or connected with both the first clamping portion 122 and the second clamping portion 123, as long as it can adjust the distance between the first clamping portion 122 and the second clamping portion 123, which is not specially limited by the present application.

[0081] In this way, by adjusting the assembly 124, the first clamping part 122 and the second clamping part 123 are moved away from each other along the Y-axis direction, so as to increase the volume of the clamping space 100, and facilitate the electronic device 02 to be placed into the clamping mechanism 12. After the electronic device 02 is placed into the clamping mechanism 12, the first clamping part 122 and the second clamping part 123 are moved closer to each other along the Y-axis direction by adjusting the assembly 124, so as to clamp and fix the electronic device 02 between the first clamping part 122 and the second clamping part 123. In addition, by adjusting the distance between the first clamping part 122 and the second clamping part 123 through the assembly 124, the clamping mechanism 12 can be applied to electronic devices 02 of different sizes, which is beneficial to improve the versatility of the clamping mechanism 12.

[0082] For example, please continue to refer to Figure 8 As shown in the figure, the first clamping part 122 is fixed on the back plate 121, and the adjusting assembly 124 is connected between the second clamping part 123 and the back plate 121. By this arrangement, since the first clamping part 122 is fixed relative to the back plate 121, the adjustment of the distance between the second clamping part 123 and the first clamping part 122 along the Y-axis direction can be realized by moving the second clamping part 123 through the adjusting assembly 124.

[0083] As for the specific structure of the above-mentioned adjusting assembly 124, the present application does not make special limitation.

[0084] For example, please continue to refer to Figure 8 , and combine Figure 9 and Figure 10 As shown in the figure, Figure 9 is a structure explosion diagram of a clamping mechanism 12 provided by an embodiment of the present application, Figure 10 is a partial sectional view (parallel to the XY plane) of the clamping mechanism 12 in Figure 9 The adjusting assembly 124 can include an adjusting knob 1241 and a screw rod 1242. The side wall surface of the back plate 121 close to the second clamping part 123 is provided with a screw hole 200, the second clamping part 123 is provided with a through hole 300, one end of the screw rod 1242 is fixedly connected with the adjusting knob 1241 after passing through the through hole 300, and the other end of the screw rod 1242 is screwed into the screw hole 200.

[0085] At this time, the adjusting knob 1241 can be rotated clockwise or counterclockwise to drive the screw rod 1242 to rotate, and the screwing amount of the screw rod 1242 in the screw hole 200 is changed, so that the distance between the first clamping part 122 and the second clamping part 123 along the Y-axis direction is adjusted, that is, the size of the clamping space 100 can be adjusted by rotating the screw rod 1242, so as to facilitate the electronic device 02 of different sizes to be placed into the clamping mechanism 12. After the electronic device 02 is placed into the clamping mechanism 12, the screw rod 1242 is tightened to clamp and fix the electronic device 02 between the first clamping part 122 and the second clamping part 123.

[0086] For example, please refer to Figure 11 , Figure 11 is a partial sectional view (parallel to the XY plane) of the clamping mechanism 12 provided by the embodiment of the application. The adjusting assembly 124 can include a pull rod 1243 and a spring 1244. The blind hole 400 is arranged on the side wall surface of the back plate 121 close to the second clamping part 123, the spring 1244 is fixed to the bottom of the blind hole 400, one end of the pull rod 1243 is fixedly connected with the second clamping part 123, and the other end of the pull rod 1243 extends into the blind hole 400 and is connected with the spring 1244.

[0087] At this time, the second clamping part 123 can be pulled along the positive direction of the Y-axis to apply a pulling force F to the second clamping part 123, and the pulling force F is transmitted to the spring 1244 through the pull rod 1243, so that the spring 1244 is stretched and deformed, and the distance between the first clamping part 122 and the second clamping part 123 is changed, that is, the size of the clamping space 100 can be adjusted by pulling the second clamping part 123 along the positive direction of the Y-axis, so as to facilitate the electronic device 02 of different sizes to be placed into the clamping mechanism 12. After the electronic device 02 is placed into the clamping mechanism 12, the pulling force F applied to the second clamping part 123 is removed, and the second clamping part 123 is driven by the elastic force of the spring 1244 to move towards the first clamping part 122, until the opposite two side edges of the electronic device 02 abut against the first clamping part 122 and the second clamping part 123 respectively, that is, the electronic device 02 can be automatically clamped by the above structure.

[0088] For example, please refer to Figure 12 and Figure 13 , Figure 12 is a partial enlarged view of A in Figure 9 , Figure 13 is a partial enlarged view of A in Figure 9The local enlarged view at B. In order to prevent the electronic device 02 from falling off the clamping mechanism 12 during the test, the first clamping part 122 is provided with a first limiting slot 1220 on the surface facing the second clamping part 123, and the second clamping part 123 is provided with a second limiting slot 1230 on the surface facing the first clamping part 122. In this way, when the electronic device 02 is clamped to the clamping mechanism 12, the opposite two side edges of the electronic device 02 can be correspondingly embedded in the first limiting slot 1220 and the second limiting slot 1230, so as to reduce the risk of the electronic device 02 falling off the clamping mechanism 12.

[0089] In some cases, when the length of the electronic device 02 along the X-axis direction is greater than the length of the first clamping part 122 and the second clamping part 123 along the X-axis direction, the edges of the electronic device 02 cannot be embedded in the first limiting slot 1220 and the second limiting slot 1230. For this purpose, please continue to refer to Figure 12 and Figure 13 It is shown that the first limiting slot 1220 penetrates the first clamping part 122 along the X-axis direction, and the second limiting slot 1230 penetrates the second clamping part 123 along the X-axis direction. In this way, by designing the first limiting slot 1220 and the second limiting slot 1230 as through slots, the situation that the electronic device 02 cannot be embedded in the first limiting slot 1220 and the second limiting slot 1230 can be avoided.

[0090] On the basis of the above, please refer to Figure 14 It is shown that Figure 14 Another structure schematic diagram of the clamping mechanism 12 provided by the embodiment of the present application. The clamping mechanism 12 can also include a guide rod 126, the guide rod 126 is fixed on the back plate 121, the second clamping part 123 is provided with a guide hole 500, and the guide rod 126 is arranged in the guide hole 500. Alternatively, the guide rod 126 is fixed on the second clamping part 123, the side wall surface of the back plate 121 close to the second clamping part 123 is provided with a guide hole 500, and the guide rod 126 is arranged in the guide hole 500. In this way, when the second clamping part 123 is moved by the adjusting assembly 124, the guide rod 126 can guide the second clamping part 123, preventing the second clamping part 123 from deflecting during movement.

[0091] It can be understood that the guide rod 126 can be one or more, and the number of the guide rod 126 is not specially limited by the present application.

[0092] For example, Figure 14The plurality of guide rods 126 are arranged in a spaced manner, and are arranged on both sides of the adjusting assembly 124. In this way, the plurality of guide rods 126 arranged in a spaced manner can make the second clamping part 123 move more smoothly relative to the first clamping part 122, and can also reduce the risk of the second clamping part 123 deflecting when clamping the electronic device 02.

[0093] Please continue to see Figure 14 As shown in

[0094] In this way, when clamping the electronic device, the electronic device 02 can be placed on the first clamping part 122 first, and then the electronic device 02 is pushed to slide along the first limiting groove 1220 until the upper edge of the electronic device 02 abuts against the positioning piece 125, which means that the electronic device 02 is placed in place, and then the distance between the first clamping part 122 and the second clamping part 123 is adjusted to clamp the electronic device 02. That is, through the cooperation of the positioning piece 125, the first clamping part 122, the second clamping part 123 and the back plate 121, the electronic device 02 can be precisely positioned, that is, the back plate 121 can limit the movement of the electronic device 02 in the Z-axis direction, the first clamping part 122 and the second clamping part 123 can limit the movement of the electronic device 02 in the Y-axis direction, and the positioning piece 125 can limit the movement of the electronic device 02 in the X-axis direction.

[0095] In addition, in order to avoid the back plate 121 from blocking the view angle of the camera module 2c of the electronic device 02, please continue to see Figure 14 , and in combination with Figure 15 As shown in Figure 15 is a schematic view of the electronic device 02 clamped on the clamping mechanism 12 in Figure 14 . Among them, the back plate 121 is provided with a avoiding opening 600, the avoiding opening 600 penetrates through the back plate 121 along the thickness direction of the back plate 121 (parallel to the Z-axis).

[0096] In this way, by arranging the avoiding opening 600, the back plate 121 can avoid blocking the view angle of the camera module 2c of the electronic device 02, that is, the clamping mechanism 12 is completely outside the view angle of the camera module 2c. In addition, since the camera decoration cover 2e of the electronic device 02 generally protrudes from the back cover 2d, the avoiding opening 600 can avoid the camera decoration cover 2e of the electronic device 02, that is, the camera decoration cover 2e can extend into the avoiding opening 600, so that the back cover 2d of the electronic device 02 can be attached to the first surface 1210 of the back plate 121, ensuring the stability of the electronic device 02 after clamping.

[0097] It can be understood that the arrangement position of the above-mentioned avoiding opening 600 on the back plate 121 can be reasonably adjusted according to the positions of the camera module 2c and the camera decoration cover 2e of the electronic device 02, and the application does not make special limitations thereto.

[0098] For example, please continue to refer to Figure 15 , in the illustrated orientation, since the camera module 2c and the camera decoration cover 2e of the electronic device 02 are arranged close to the upper left corner of the back cover 2d, the avoiding opening 600 is arranged at the upper left corner of the back plate 121. When the electronic device 02 is clamped to the clamping mechanism 12, the back cover 2d is attached to the first surface 1210 of the back plate 121, and the camera decoration cover 2e extends into the avoiding opening 600.

[0099] In some cases, the electronic device 02 needs to take pictures of different scenes during testing, and there is a certain distance between different scenes. Therefore, on the basis of the above, please refer to Figure 16 , in the illustrated orientation, Figure 16 is another structural schematic diagram of the test device 01 provided by the embodiment of the application. The test device 01 can further include a moving platform 30, and the driving mechanism 20 is arranged on the moving platform 30. In this way, by arranging the driving mechanism 20, the base 11 and the plurality of clamping mechanisms 12 on the moving platform 30, the moving platform 30 can carry the driving mechanism 20, the base 11, the plurality of clamping mechanisms 12 and the plurality of electronic devices 02 to move between different scenes, thereby facilitating the improvement of test efficiency.

[0100] For example, please refer to Figure 17 , in the illustrated orientation, Figure 17 is a schematic diagram of the test device 01 in Figure 16 moving between different scenes. Each electronic device 02 in the same group of tests needs to take pictures of three scenes, respectively, that is, scene 1, scene 2 and scene 3. Among them, scene 1 is a restaurant scene model, scene 2 is an office scene model, and scene 3 is a bar scene model.

[0101] During the test, the mobile platform 30, carrying the drive mechanism 20, the base 11, multiple clamping mechanisms 12, and multiple electronic devices 02, first moves to scene 1. Then, the drive mechanism 20 drives the base 11 to rotate, so that the multiple electronic devices 02 clamped on the multiple clamping mechanisms 12 take pictures of the same area in scene 1 in turn. After each electronic device 02 in this test has finished taking pictures of scene 1, the mobile platform 30 moves to scene 2, so that the multiple electronic devices 02 clamped on the multiple clamping mechanisms 12 take pictures of the same area in scene 2 in turn, and so on, until scene 3 is completed.

[0102] This ensures consistency in the shooting area of ​​multiple electronic devices 02 for the same scene.

[0103] It is understood that the aforementioned mobile platform 30 can be an AGV (Automated Guided Vehicle), a sliding rail mechanism, etc., and this application does not make any special restrictions on it.

[0104] This application also provides a testing device 01, please refer to... Figure 18 As shown, Figure 18 This is a schematic diagram of another testing device 01 provided in an embodiment of this application. The testing device 01 may include a driving mechanism 20, a base 11, and multiple clamping mechanisms 12. The multiple clamping mechanisms 12 are fixed to the base 11 and arranged along a first straight line C. The driving mechanism 20 is connected to the base 11 and is used to drive the base 11 to move along the first straight line C. In this way, by driving the base 11 to move along the first straight line C via the driving mechanism 20, any clamping mechanism 12 on the base 11 and its corresponding electronic device 02 can be placed. Figure 18 (Not shown) is transported to the test point for testing. Compared to manual testing one by one, the above-mentioned testing device 01 can also greatly improve the consistency of the spatial position of multiple electronic devices 02 during testing, that is, the deviation between the actual position of each electronic device 02 and the test point is small, which helps to reduce the difficulty of subsequent analysis and comparison of test results.

[0105] Further reading is available upon request. Figure 18 The multiple clamping mechanisms 12 can be arranged at equal intervals along the first straight line C.

[0106] For example, please continue to see Figure 18 As shown, Figure 18 The base 11 is equipped with three clamping mechanisms 12, which are arranged at equal intervals along a first straight line C. The distance between the center points of any two adjacent clamping mechanisms 12 is d. This allows for the initial selection of any clamping mechanism 12 on the base 11 and its corresponding electronic device 02 during testing. Figure 18(Not shown in the image) The current location is the test point, for example, using... Figure 18 The clamping mechanism 12 and the corresponding electronic device 02 located on the far right of the base 11 in the shown orientation are currently at the test point. Then, each time, the drive mechanism 20 simply moves the base 11 a distance d to the right along the first straight line C, allowing the adjacent clamping mechanism 12 and the corresponding electronic device 02 on the left to accurately enter the test point for testing. This process is repeated to complete the testing of a group of three electronic devices 02. Through this structural design, the consistency of the spatial positions of multiple electronic devices 02 during testing is significantly improved; that is, the deviation between the actual position of each electronic device 02 and the test point is small, which helps reduce the difficulty of subsequent analysis and comparison of test results.

[0107] It is understood that the aforementioned drive mechanism 20 can be a linear motor, cylinder, or other mechanism that is itself a linear drive mechanism. The aforementioned drive mechanism 20 can also be a drive mechanism that can convert rotary motion into linear motion through an intermediate transmission mechanism. For example, the drive mechanism 20 can be a servo motor or a stepper motor. The output shaft 22 of the servo motor or the stepper motor is equipped with a gear, and the base 11 is equipped with a rack. Through the meshing of the gear and the rack, the rotation of the output shaft 22 of the servo motor or the stepper motor can be converted into the movement of the base 11.

[0108] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0109] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
