Description

Technical Field

[0001] The present invention relates to the technical field of automated equipment and testing methods, and more specifically to a CSAR mobile phone automated testing device and testing method. Background Art

[0002] The full English name of SAR is Specific Absorption Rate, which is generally called "specific absorption rate" or "characteristic absorption rate" in Chinese. It is the absorption ratio of electromagnetic wave energy of a mobile phone or wireless product. Its definition process is as follows: Under the action of an external electromagnetic field, an induced electromagnetic field will be generated in the human body. Since various organs of the human body are lossy dielectrics, an electric current will be generated in the internal electromagnetic field, resulting in the absorption and dissipation of electromagnetic energy. In biodosimetry, the SAR value is used to characterize this physical process. And CSAR refers to rapid SAR testing, which can quickly evaluate the electromagnetic radiation of mobile phones.

[0003] However, when evaluating the electromagnetic radiation of a mobile phone, long-term testing is required, and different sides of the mobile phone and different angles with respect to the human body need to be tested. In the traditional method, although there are SAR calculation methods, there is no particularly good measurement method that can ensure the accuracy of height, angle, position, etc. in each measurement. These are also the reasons affecting the test accuracy. And if the mobile phone is directly placed on the measurement station, the mobile phone cannot switch angles. Each time the angle or height is switched, an auxiliary part is required to stabilize the mobile phone; at the same time, the test time is long and a large amount of data needs to be recorded, often resulting in data errors;

[0004] And a mobile phone needs to go through several rounds of testing to evaluate the electromagnetic radiation of the mobile phone in different states. Then, when switching the mobile phone to different states, different programs need to be written. During the process of writing the program, the mobile phone needs to be connected to the writing device, and this connection is through an interface and a plug.

[0005] In the traditional technology, all the above processes / steps are completed manually, with low efficiency, which affects the automation process and the detection process.

[0006] In view of this, the applicant has proposed the following technology. Summary of the Invention

The lower positioning plate is fixedly installed, and the positioning motor drives the upper positioning plate to move relative to the lower positioning plate to perform a clamping or releasing action.

[0016] The test method of the above CSAR mobile phone automatic test device includes the following steps:

[0017] S1: Place the mobile phone on the rack and connect the charging mechanism, and charge the mobile phone while placing it.

[0018] S2: Grab the mobile phone through the multi-axis manipulator, and the mobile phone is separated from the charging mechanism while grabbing the mobile phone.

[0019] S3: The multi-axis manipulator moves the mobile phone to the CCD recognition station, takes a picture of the current lower surface of the mobile phone through the CCD industrial camera, and transmits the picture to the control system, and the control system identifies whether the current mobile phone is face up or back up.

[0020] S4: Measure the size of the mobile phone through the measuring mechanism. The multi-axis manipulator moves the first edge of the mobile phone towards the measuring mechanism. When the measuring mechanism detects the first edge of the mobile phone, the multi-axis manipulator stops moving. After the multi-axis manipulator moves away from the measuring mechanism and rotates 90°, the multi-axis manipulator moves the second edge of the mobile phone towards the measuring mechanism again. When the measuring mechanism detects the second edge of the mobile phone, the multi-axis manipulator stops moving. Thus, repeat the above actions for the third edge and the fourth edge of the mobile phone, and calculate the size of the mobile phone through the control system;

[0021] S5: The multi-axis manipulator drives the mobile phone to move to the alignment station, and calibrates the position in the XYZ directions. If the trigger position is the set coordinate, it is determined that the coordinate is accurate; if there is a deviation in the trigger position, coordinate compensation is performed;

[0022] S6: Control the multi-axis manipulator to place the mobile phone on the detection station at different angles through the control program, measure data through the measurement sensor, and transmit the measurement data to the control system, and the control system converts and calculates the radiation dose;

[0023] S7: The multi-axis manipulator drives the mobile phone to move to the flipping component. After the sensor on the fixture of the flipping component senses that the mobile phone enters between the two fixtures, the clamping cylinder controls the two sets of fixtures to clamp the mobile phone, and at the same time the multi-axis manipulator moves up to release the mobile phone; the rotating cylinder rotates 180°, the multi-axis manipulator moves down and sucks the mobile phone tightly again through the picking suction cup, the clamping cylinder drives the two sets of fixtures to open, after releasing the mobile phone, the multi-axis manipulator drives the mobile phone to move away from the flipping component, and moves to the CCD recognition station again to identify whether the current mobile phone is face up or back up;

[0024] S8: After repeating step S6, jump to step S9;

[0025] S9: Move the mobile phone into the USB automatic plugging and unplugging component through the multi-axis manipulator. The mobile phone enters between the upper positioning plate and the lower positioning plate, and the interface of the mobile phone faces the plug. The positioning motor drives the upper positioning plate to move down, and clamps the mobile phone through the upper positioning plate and the lower positioning plate, and the multi-axis manipulator releases; the CCD component takes a photo of the interface side of the mobile phone and transmits it to the control system. The control system analyzes the position of the mobile phone interface, controls the plug installation platform to move in the YZ three-axis directions, and after moving to align with the mobile phone interface, the plug installation platform moves in the X direction, and the plug is inserted into the mobile phone interface. The mobile phone is written and formed to change the state of the mobile phone. After writing the data, the multi-axis manipulator grabs the mobile phone again, the plug installation platform moves reversely in the X direction to reset, and the positioning motor drives the upper positioning plate to move up to release the mobile phone;

[0026] S10: Repeat steps S3 - S9 at least once, and then end the test.

[0027] In the further test steps, in step S4, the position of the CCD recognition station is fixed. Through system settings, the multi-axis manipulator on the CCD recognition station has fixed XYZ coordinates with the positioning rod as the reference. The first set of sensors on the measuring mechanism are distributed vertically. The multi-axis manipulator moves in the X direction with the YZ coordinates unchanged. The mobile phone can correctly enter between the first set of sensors, and the first edge of the mobile phone is sensed by the first set of sensors. When sensing, the distance between the positioning rod and the first set of sensors in the X direction is the local length a of the mobile phone. When the third edge of the mobile phone is sensed by the first set of sensors, the distance between the positioning rod and the first set of sensors in the X direction when sensing is the local length b of the mobile phone. a + b is the length of the mobile phone. Similarly, the width of the mobile phone can be calculated. At the same time, through the above method, it can also be detected whether the positioning rod is located at the exact center of the mobile phone;

[0028] In step S5, the alignment mechanism has a second sensor group, and the second sensor group is fixed at the alignment station. The multi-axis manipulator moves to the alignment mechanism, and the second sensor group triggers with the positioning rod. If the position coordinates of the current multi-axis manipulator are consistent with the standard coordinates when triggered, it is determined that the position is accurate;

[0029] If the position coordinates of the current multi-axis manipulator are inconsistent with the standard coordinates when triggered, it is determined that there is a position deviation and displacement compensation is required;

[0030] In step S6, the detection time that the mobile phone stays at the detection station is X, and X is set by the control system. The measurement sensor measures the electric field value at the detection station and transmits the electric field value to the control system, and then calculates the SAR value.

[0031] From the above technical solutions, compared with the prior art, the present invention has the following beneficial technical effects:

[0032] 1. The present invention tests the radiation data of the mobile phone in an automated manner, which is more accurate than the traditional test method;

[0033] 2. The present invention is provided with a charging mechanism on the rack. When one mobile phone is being detected, other mobile phones are charged to ensure that the mobile phone to be detected has sufficient power and ensure the smooth progress of the detection;

[0034] 3. The present invention is provided with a CCD recognition station, which can automatically recognize the front or back of the mobile phone. After recognition, the size of the mobile phone is measured by the measuring mechanism, so that the control system can calculate the coordinate position of the multi-axis manipulator moving to the detection station according to the size of the mobile phone to ensure the detection effect;

[0035] 4. The present invention is provided with a positioning mechanism, which measures the coordinates of the current multi-axis manipulator. If the multi-axis manipulator is offset, it can be automatically compensated by the positioning mechanism to ensure the correct movement of the multi-axis manipulator.

[0036] 5. The present invention is provided with a flipping mechanism, which can automatically flip the mobile phone by 180°, and the whole flipping process is fast.

[0037] 6. The present invention tests the mobile phone in various different states. Then, through the USB automatic plugging and unplugging component, different programs / signals can be written into the mobile phone to change the state of the mobile phone, which is convenient for testing the mobile phone in different states.

[0051] Now, the present invention will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only schematically showing the basic structure of the present invention, so they only show the components related to the present invention.

[0052] The CSAR mobile phone automatic testing device, as Figure 1A shown, includes: a control system. The control system is used to control the operation of the whole machine. There are many different models or types of sensors in the entire CSAR mobile phone automatic testing device. The data detected by the sensors are all fed back to the control system, and the control system issues instructions to control each mechanism / component to perform corresponding actions. In particular, the most core of the control system is to calculate the electromagnetic radiation of the mobile phone by measuring the electric field value transmitted by the sensor;

[0053] Specifically, the calculation method of the control system can adopt a SAR rapid testing method in the patent number: 201310281845.8.

[0054] The machine platform 100, as the carrier of the whole device, is provided with multiple stations on the machine platform 100. Specifically, it includes: a multi-axis manipulator 200, a loading and unloading component 300, a CCD recognition station 400, a detection station 500, a calibration station 600, a flipping component 700, and a USB automatic plugging and unplugging component 800. As Figure 1A and Figure 11 shown, the multi-axis manipulator 200, the loading and unloading component 300, the CCD recognition station 400, the detection station 500, the calibration station 600, the flipping component 700, and the USB automatic plugging and unplugging component 800 are all located on or exposed on the surface of the machine platform 100, and the multi-axis manipulator 200 is roughly located in the middle of the machine platform 100. The loading and unloading component 300, the CCD recognition station 400, the detection station 500, the calibration station 600, the flipping component 700, and the USB automatic plugging and unplugging component 800 are distributed around the multi-axis manipulator 200. The whole layout is compact, and the multi-axis manipulator 200 can move to each station with a small space distance, reducing the volume of the whole machine.

[0055] It should be noted that Figure 1A and Figure 11In the figure, a mobile phone 900 is placed on each of the three inspection stations 500. In actual inspection, the mobile phones are not placed on the three inspection stations 500 at the same time. The multi-axis manipulator 200 is required to place the mobile phones 900 on the inspection stations 500 in a set order for inspection. Figure 1A and Figure 11 The three mobile phones are placed separately in the figure just to inform the positions where the mobile phone 900 is placed during the test.

[0056] The multi-axis manipulator 200 drives the mobile phone 900 to move on each workstation. The multi-axis manipulator 200 is at least a three-axis manipulator, and a material picking suction cup 210 is provided on the multi-axis manipulator 200.

[0057] like Figure 1A As shown, the multi-axis manipulator 200 is at least a 3-axis manipulator, and in this embodiment is set as a 6-axis manipulator, and a material picking suction cup 210 is set at the end of the multi-axis manipulator 200, which grabs the mobile phone by adsorption and will not scratch the surface of the mobile phone. There are four material picking suction cups 210, which can stably grab the mobile phone. When grabbing, the external suction device inhales air, and the material picking suction cup 210 sucks the mobile phone. When releasing the mobile phone, the external suction device stops or outputs air, and the material picking suction cup 210 releases the mobile phone.

[0058] A positioning rod is provided at the end of the multi-axis manipulator 200, and the material picking suction cup 210 is installed at the end of the positioning rod, and the positioning rod is a straight rod.

[0059] The movement principle of the multi-axis manipulator 200 can refer to the six-axis manipulator in the prior art, and the specific structure of the multi-axis manipulator will not be described separately here.

[0060] like Figure 2 As shown, the loading and unloading assembly 300 includes: a bottom plate 310, a material rack 320, a charging mechanism 330 and an indicator light assembly 340. The bottom plate 310 serves as a support for the entire loading and unloading assembly 300, so that the entire loading and unloading assembly 300 can be assembled as a whole and then installed on the machine 100, simplifying the assembly process; the material rack 320 is composed of a plurality of L-shaped brackets 321 obliquely arranged on the bottom plate 310, and each L-shaped bracket 321 forms a mounting position. The mobile phone 900 is placed obliquely on the mounting position and the front of the mobile phone is exposed to the outside for easy grasping by the multi-axis manipulator. When the mobile phone 900 is placed, the mounting position is in contact with the edge of the mobile phone 900; Figure 11 As shown, it is a schematic diagram of the multi-axis manipulator 200 grabbing the mobile phone 900, and the L-shaped bracket 321 allows the multi-axis manipulator 200 to be lifted slightly to detach from the installation position when grabbing the mobile phone 900, and take the mobile phone 900 out of the rack 320, so that the grabbing and placing processes are very convenient;

[0061] A charging mechanism is provided at the bottom corresponding to each L-shaped bracket 321. The charging mechanism is installed on the L-shaped bracket 321 in a limiting manner. The limiting manner here can be clamping, inserting, etc. According to the detection of different mobile phone models, the specific models of the charging mechanisms are also different. According to the existing mobile phone interface types, there are mainly three types: TYPE-C, MicroUSB, and Lightning. Then, the charging connectors in the charging mechanisms also change the charging mechanisms according to the models of the detected mobile phones 900. The clamping and inserting methods can quickly replace the charging mechanisms.

[0062] When the mobile phone 900 is placed on the rack 320, the charging mechanism charges the mobile phone 900 at the same time. Only when charging, the mobile phone 900 is considered to be placed correctly, otherwise the placement is inaccurate.

[0063] The described indicator light assembly 340 is provided corresponding to each L-shaped bracket 321. When the mobile phone 900 is charging or placed correctly, the indicator light assembly 340 lights up, which can remind the user that the mobile phone 900 is installed correctly. When the indicator light assembly 340 is off, it means that there is no mobile phone 900 placed or the mobile phone 900 is placed incorrectly.

[0064] Specifically, in this embodiment, six L-shaped brackets 321 are provided, which can simultaneously accommodate six mobile phones for charging. The untested mobile phones are charged during the waiting process. Because the detection time for each mobile phone is relatively long, maintaining the charging state ensures that the mobile phone has sufficient power when the mobile phone 900 is detected, so as to avoid the situation of power shortage during the detection process and affect the detection progress.

[0065] As shown in FIGS. 1-2, the CCD recognition station 400 includes: a glass plate 410, a CCD industrial camera (not shown in the figure) provided at the bottom of the glass plate 410, and a measuring mechanism 420;

[0066] The CCD industrial camera is provided below the glass plate 410, and the CCD industrial camera uses a 20 million pixel high-definition CCD camera. The maximum field of view can support 12-inch tablet computer products. With an adaptive vision recognition algorithm, it can work in a normal lighting environment without the need for an additional lighting device;

[0067] Although the CCD industrial camera is not shown in the figure, the general structure and principle of the CCD industrial camera should be known to those skilled in the art; the described glass plate 410 is made of special material glass, which ensures light transmittance while not generating reflected light that affects CCD recognition.

[0068] The shooting of the CCD industrial camera mainly aims to identify whether the current mobile phone is in the front or the back. Since there is a camera on the back of the mobile phone, the CCD industrial camera is connected to the control system, and the captured pictures are transmitted to the control system for analysis. The front or back of the mobile phone can be distinguished by identifying the mobile phone camera, so as to identify the orientation of the mobile phone and bring convenience to the subsequent detection work.

[0069] The described measuring mechanism 420 is arranged beside the glass plate 410, and the measuring mechanism 420 protrudes vertically. The measuring mechanism 420 includes: a first U-shaped bracket 421 and a set of symmetric first sensor groups 422 arranged on the first U-shaped bracket 421, and the size of the mobile phone is measured by the first sensor groups 422. The specific measurement method is as follows: First, a positioning rod is arranged on the multi-axis manipulator 200, and a basic coordinate of the multi-axis manipulator 200 on the CCD recognition station 400 is set. Each time the multi-axis manipulator 200 resets to the CCD recognition station 400, this coordinate is used as the benchmark. It is set to keep the position of the multi-axis manipulator 200 unchanged in the YZ direction, and the position of the measuring mechanism 420 is also fixed. Then, the position of the multi-axis manipulator 200 in the X direction is changed, and the multi-axis manipulator 200 is moved towards the measuring mechanism 420. When the first sensor group 422 just detects the edge of the mobile phone 900, the operation stops. At this time, the distance between the positioning rod and the measuring mechanism 420 is the local size of the mobile phone. The multi-axis manipulator 200 resets to the reference coordinate, and then the opposite side of the mobile phone is measured. The superposition of the two measurement data is the width size of the mobile phone. In this way, the length size of the mobile phone is measured again, which is convenient for correctly moving the mobile phone to the detection station 500 subsequently.

[0070] It can also be: a basic coordinate of the multi-axis manipulator 200 on the CCD recognition station 400, and the first sensor group 422 is also fixed on the CCD recognition station 400. Then the distance in the X direction between the two is fixed at L. Then during measurement, when the first sensor group 422 touches the edge of the mobile phone, the moving distance of the multi-axis manipulator 200 in the X direction is L1. Then, L - L1 is the local width of the mobile phone. Then the opposite side of the mobile phone is measured. The moving distance of the multi-axis manipulator 200 in the X direction is L2, and L - L2 is the local width of the mobile phone. Then the overall width of the mobile phone is: (L - L1) + (L - L2).

[0071] In addition, through the above method, it can also be confirmed whether the positioning rod is located at the center position of the mobile phone 900, which is convenient for correcting the position of the mobile phone 900 on the detection station 500 during subsequent detection.

[0072] Please refer to Figure 1AAs shown in the figure, there are three detection stations 500 set on the machine platform 100. A measurement sensor is set on each detection station 500. The multi-axis manipulator 200 moves the mobile phone 900 to the detection station 500 and acts on the detection station 500 at different angles and heights. The measurement sensor measures the data and transmits the data to the control system, and the control system analyzes the data; the measurement sensor measures the electric field value at the detection station and transmits the electric field value to the control system. The specific calculation method of the control system can adopt a SAR rapid test method in 201310281845.8.

[0073] As Figure 1A shown, there are multiple alignment mechanisms 610 set on the alignment station 600. A positioning rod is set on the multi-axis manipulator 200. Through the cooperation of the positioning rod and the alignment mechanism 610, the position is calibrated. The alignment mechanism 610 is set on any one or more detection stations 500, including: a first alignment mechanism and a second alignment mechanism. Both the first alignment mechanism and the second alignment mechanism include: a second U-shaped bracket 611 and a set of symmetric second sensor groups 612 set on the second U-shaped bracket 611; both the first sensor group 422 and the second sensor group 612 are communicatively connected to the control system.

[0074] When the multi-axis manipulator 200 moves into the alignment mechanism 610, the positioning rod on the multi-axis manipulator 200 and the second sensor group 612 calibrate the current coordinates. Through calculation, the subsequent running track of the multi-axis manipulator 200 is controlled, and it can be correctly placed on the detection station 500 for detection;

[0075] As Figure 9 shown, it is the detection position of the mobile phone on the first detection station 500. The mobile phone 900 is driven by the multi-axis manipulator 200 and placed vertically above the first detection station 500 for side detection.

[0076] As Figure 10 shown, it is the detection position of the mobile phone on the second detection station 500. The mobile phone 900 is driven by the multi-axis manipulator 200 and placed vertically above the second detection station 500 for front / back detection.

[0077] On the detection station 500, each mobile phone is detected at least at two different angles. For example: the first is horizontal placement detection, and the second is placement detection at an inclination of 15°.

[0078] Tests are carried out at different heights and angles on different detection stations 500, corresponding to imitating the mobile phone at a certain position on the human body, such as the left and right beside the back of the head, the degree of closeness, the front and back sides beside the body and the degree of closeness for testing, and the test data is more comprehensive.

[0079] As Figure 3As shown, the flipping assembly 700 includes: a clamping cylinder 710, a rotating cylinder 720, and two sets of clamps 730. The clamps 730 are arranged in pairs. The rotating cylinder 720 drives the entire clamp to rotate at least 180°. The clamping cylinder 710 drives the relative clamping or opening between the two clamps 730.

[0080] Specifically, during CSAR automated testing, after the multi-axis manipulator 200 grabs the mobile phone 900 with its material taking suction cup 210, the flipping assembly 700 clamps and flips the mobile phone, facilitating further testing after the mobile phone is flipped. The rotating cylinder 720 is connected to the clamp 730, and the rotating cylinder 720 drives the clamp 730 to perform a concentric rotational motion; the clamping cylinder 710 drives the two sets of clamps 730 to clamp inward or open outward, realizing the clamping and loosening of the mobile phone 900, or adjusting the clamping force; sensors are provided on the two sets of clamps 730, and the sensors are generally arranged on the inner sides of the two clamps 730 for detecting the in-position state of the test prototype.

[0081] Contact strips 740 are provided on the opposite surfaces of the clamp 730. The contact strips 740 are made of silicone plastic material, but the material is not limited to this embodiment; when clamping the mobile phone, the contact strips 740 contact the surface of the mobile phone. The flexible plastic material has a certain buffering and protective effect during clamping, avoiding damage to the prototype and affecting the accuracy of the test.

[0082] Further, the clamping cylinder 710 and the rotating cylinder 720 are installed on the mounting bracket and hidden inside the protective cover 750, playing a protective role, and the clamp 730 extends out of the protective cover 750.

[0083] As Figures 4 - 7 shown, the USB automatic plugging and unplugging assembly 800 includes: a bracket 810, a CCD module 820 assembled on the bracket 810, a plug assembly 830, and a positioning module 840. The CCD module 820, the plug assembly 830, and the positioning module 840 are all connected to a control system and are controlled by the control system to operate.

[0084] The bracket 810 plays a bearing role, mainly installing the entire USB automatic plugging and unplugging device on the CSAR mobile phone automated testing equipment. The specific structure and shape of the bracket 810 can be various. Specifically, the bracket 810 is in a plate shape in this embodiment.

[0085] A Z-axis 850 is installed on the bracket 810. The CCD module 820 and the plug assembly 830 are commonly installed on the Z-axis 850 through a sliding seat and linearly reciprocate along the Z-axis 850 synchronously; the Z-axis 850 can be structures such as a guide rail or a slide rail. The Z-axis 850 has a housing, playing a protective role.

[0086] The described CCD module 820 and the plug component 830 are driven by the Z-axis motor 851 to move linearly back and forth along the Z-axis 850 synchronously. The Z-axis motor 851 drives the sliding seat to move along the Z-axis 850.

[0087] On the described sliding seat, a first mounting plate for assembling the CCD module 820 and a second mounting plate for assembling the plug component 830 are formed. After the CCD module 820 and the plug component 830 are installed, Figure 4 As shown in the indicated orientation, they are distributed vertically. The CCD module 820 is located above the plug component 830, and the relative distance between the two in the Z-axis direction is fixed.

[0088] The described sliding seat functions to drive the sliding and provide support for installation, and the specific shape of the sliding seat can be replaced.

[0089] The described CCD module 820 includes: a main unit 821 and a CCD camera 822. The CCD camera 822 faces the direction of the positioning module 840. The CCD camera 822 takes pictures of the mobile phone 900 and transmits the pictures to the control system. By analyzing the control system, the interface position of the mobile phone 900 is determined, and then the plug component 830 is controlled to move to the corresponding interface position of the mobile phone 900 and insert into the interface of the mobile phone 900.

[0090] CCD recognition technology, CCD industrial recognition systems, etc. have been popularized and applied in existing automated equipment. The CCD module 820 in this embodiment uses a 6-million-pixel industrial CCD to automatically recognize the interfaces of different test prototypes, and adopts an AI vision recognition algorithm, which can recognize interfaces of different colors and different materials with high recognition accuracy; the shape, angle, etc. of the product are recognized through CCD.

[0091] The CCD module 820 is used to collect high-definition images of the mobile phone 900. After the images are digitally processed, the generated positioning data is used to achieve positioning control and control the movement of the plug component 830 to accurately insert into the interface of the mobile phone 900.

[0092] The described plug component 830 includes: an X-axis component 831, a Y-axis component 832, a plug mounting table 833, and a plug 801. The plug 801 is fixedly installed on the plug mounting table 833 and moves synchronously with the plug mounting table 833 on the X-axis component 831 and the Y-axis component 832.

[0093] The model of the described plug 801 is replaced according to the interface model of the mobile phone to be detected. For example, Figure 6As shown, the plug mounting table 833 includes an upper mounting table 8331 and a lower mounting table 8332. After the upper mounting table 8331 and the lower mounting table 8332 are assembled, an installation cavity for fixing the plug 801 is formed therebetween. The plug 801 is connected to the wire 302 within the installation cavity; the plug 801 protrudes from the front end of the plug mounting table 833.

[0094] The upper mounting table 8331 and the lower mounting table 8332 are locked by screws, or the upper mounting table 8331 and the lower mounting table 8332 are limited and fixed by a locking member, which is convenient for disassembly. After the upper mounting table 8331 is disassembled, the replacement of the plug 801 can be facilitated. Specifically, in this embodiment, the upper mounting table 8331 and the lower mounting table 8332 are locked by screws. According to the existing mobile phone interface types, there are mainly three types: TYPE-C, Micro USB, and Lightning. According to the different models of the mobile phone to be detected, the model of the plug 801 can be correspondingly replaced to match the mobile phone interface model.

[0095] The plug mounting table 833 is mounted on the X-axis assembly 831, and the X-axis assembly 831 is mounted on the Y-axis assembly 832. The X-axis assembly and the Y-axis assembly can both be lead screw assemblies, and the lead screw is rotated by a lead screw motor to drive the plug mounting table 833 to move precisely in the X and Y directions; or the X-axis assembly and the Y-axis assembly can both be cylinder and slide rail assemblies, and the plug mounting table 833 is driven by a cylinder to move along the slide rail in the X and Y directions.

[0096] Specifically, as Figure 6 shown, the X-axis assembly 831 includes a first base 8311, an X-axis motor 8312, and a lead screw 8313. The plug mounting table 833 is connected to the lead screw 8313 through a first slide block 8314. The rotation of the X-axis motor 8312 drives the first slide block 8314 to move linearly in the X direction, and further drives the plug mounting table 833 to move in the X direction;

[0097] As Figure 7 shown, the Y-axis assembly 832 includes a second base 8321, a Y-axis motor 8322, and a lead screw 8323. The Y-axis assembly 832 is connected to the lead screw 8323 through a second slide block 8324. The rotation of the Y-axis motor 8322 drives the second slide block 8324 to move linearly in the Y direction, and further drives the plug mounting table 833 and the X-axis assembly 831 to move in the Y direction;

[0098] Through the above, the movement of the plug 801 in the XYZ three-axis directions can be realized to correspond to the interface position of the mobile phone 900.

[0099] As Figure 4As shown, the positioning module 840 is positioned and supported at the front end of the plug assembly 830 by means of the support rod 844, and the positioning module 840 is fixed at least in the X direction. The positioning module 840 includes: an upper positioning plate 841, a lower positioning plate 842 and a second motor 843. One of the upper positioning plate 841 and the lower positioning plate 842 is positioned relative to the bracket 810, and the other is driven by the second motor 843 to perform a clamping or loosening action between the upper positioning plate 841 and the lower positioning plate 842. Here, it is set that the lower positioning plate 842 is fixed, and the upper positioning plate 841 is driven by the second motor 843 to move up and down;

[0100] Further, the first base 8311 is provided with a slide rail in the direction parallel to the lead screw 8313. The plug mounting table 833 is mounted on the X-axis assembly 831 through the slider 8315. The slider 8315 is fixed to the first slide seat 8314, and the slide rail serves to assist the movement of the slider 8315;

[0101] Similarly, the second base 8321 is provided with a slide rail in the direction parallel to the lead screw 8323. The X-axis assembly 831 is mounted on the Y-axis assembly 832 through the slider 8325. The slider 8325 is fixed to the second slide seat 8324, and the slide rail serves to assist the movement of the slider 8325;

[0102] During use, the mobile phone is sent between the upper positioning plate 841 and the lower positioning plate 842 manually or by a manipulator. Then, the second motor 843 drives the upper positioning plate 841 to move downward to clamp the mobile phone.

[0103] During use, the mobile phone is placed on the positioning module 840 by a manipulator or manually; the second motor 843 drives the upper positioning plate 841 to move downward, and the mobile phone is clamped by the upper positioning plate 841 and the lower positioning plate 842; the CCD module 820 moves downward in the Z-axis direction. After moving downward, a picture of the positioned mobile phone 900 is taken and transmitted to the control system. The current position of the mobile phone 900 and the position of the interface are analyzed through the control system; the CCD module 820 resets, and then the plug assembly 830 is controlled by the control system to move in the ZY direction until it is aligned with the interface; the control system controls the plug assembly 830 to move in the X direction, and the plug 801 is inserted into the socket of the mobile phone 900 to write data.

[0104] After the data writing is completed, the plug assembly 830 moves and resets in the X direction, the plug 801 is pulled out, and the mobile phone is transmitted to a designated place manually or by a manipulator.

[0105] Through this CSAR mobile phone automatic measuring device, automatic measurement can be realized, and the operation is simpler and more convenient.

[0106] The test method of the CSAR mobile phone automatic test device includes the following steps:

[0107] S1: Place the mobile phone on the rack and connect it to the charging mechanism, and charge the mobile phone while placing it.

[0108] S2: Grasp the mobile phone with the multi-axis manipulator, and the mobile phone disconnects from the charging mechanism while being grasped.

[0109] S3: The multi-axis manipulator moves the mobile phone to the CCD recognition station, takes a picture of the current lower surface of the mobile phone through the CCD industrial camera, and transmits the picture to the control system. The control system identifies whether the current mobile phone is face up or back up.

[0110] S4: Measure the size of the mobile phone through the measuring mechanism. The multi-axis manipulator moves the first edge of the mobile phone towards the measuring mechanism. When the measuring mechanism detects the first edge of the mobile phone, the multi-axis manipulator stops moving. After the multi-axis manipulator moves away from the measuring mechanism and rotates 90°, the multi-axis manipulator moves the second edge of the mobile phone towards the measuring mechanism again. When the measuring mechanism detects the second edge of the mobile phone, the multi-axis manipulator stops moving. In this way, repeat the above actions for the third edge and the fourth edge of the mobile phone, and calculate the size of the mobile phone through the control system.

[0111] S5: The multi-axis manipulator drives the mobile phone to move to the alignment station for calibration of the position in the XYZ directions.

[0112] S6: Control the multi-axis manipulator to place the mobile phone on the detection station at different angles through the control program, measure the data through the measuring sensor, and transmit the measured data to the control system. The control system converts and calculates the radiation dose.

[0113] S7: The multi-axis manipulator drives the mobile phone to move to the flipping assembly. After the sensor on the fixture of the flipping assembly senses that the mobile phone enters between the two fixtures, the clamping cylinder controls the two groups of fixtures to clamp the mobile phone, and at the same time the multi-axis manipulator moves up to release the mobile phone; the rotating cylinder rotates 180°, the multi-axis manipulator moves down and sucks the mobile phone tightly again through the picking suction cup, the clamping cylinder drives the two groups of fixtures to open, and after releasing the mobile phone, the multi-axis manipulator drives the mobile phone to move away from the flipping assembly and moves to the CCD recognition station again to identify whether the current mobile phone is face up or back up.

[0114] S8: After repeating step S6, jump to step S9.

[0115] S9: The mobile phone is moved by a multi-axis robot arm into the USB automatic plugging and unplugging component. The mobile phone enters between the upper positioning plate and the lower positioning plate, and the interface of the mobile phone faces the plug. The positioning motor drives the lower movement of the upper positioning plate. The mobile phone is clamped by the upper positioning plate and the lower positioning plate, and the multi-axis robot arm releases it. The CCD component takes a photo of the interface side of the mobile phone and transmits it to the control system. The control system analyzes the position of the mobile phone interface, controls the movement of the plug installation platform in the YZ three-axis directions. After moving to align with the mobile phone interface, the plug installation platform moves in the X direction, and the plug is inserted into the mobile phone interface. The mobile phone is written and formed to change the state of the mobile phone. After the data writing is completed, the multi-axis robot arm grabs the mobile phone again. The plug installation platform moves reversely in the X direction to reset. The positioning motor drives the upper movement of the upper positioning plate to release the mobile phone;

[0116] S10: After repeating steps S3 - S9 at least once, the test ends.

[0117] Further, before the detection of the mobile phone, the movement trajectory of the multi-axis robot arm has been set by the control system.

[0118] Further, in step S4, the position of the CCD recognition station is fixed. Through system settings, the multi-axis robot arm has fixed XYZ coordinates at the CCD recognition station. When measuring the size of the mobile phone, each reset of the multi-axis robot arm is reset to the fixed XYZ coordinates, and then the next full measurement is carried out again;

[0119] The first group of sensors on the measuring mechanism are distributed vertically. The multi-axis robot arm moves in the X direction with the YZ coordinates unchanged. The mobile phone can correctly enter between the first group of sensors, and the first edge of the mobile phone is sensed by the first group of sensors. The distance between the positioning rod and the first group of sensors in the X direction during sensing is the partial length a of the mobile phone. The multi-axis robot arm is reset to the fixed XYZ coordinates. After controlling the mobile phone to rotate 180°, the third edge of the mobile phone is measured. When the third edge of the mobile phone is sensed by the first group of sensors, the distance between the positioning rod and the first group of sensors in the X direction during sensing is the partial length b of the mobile phone. a + b is the length of the mobile phone. Similarly, the width of the mobile phone can be calculated. At the same time, whether the positioning rod is located at the center of the mobile phone can also be detected through the above method;

[0120] More specifically, the positioning coordinates of the multi-axis manipulator at the CCD recognition station are set to (0, 0, 0). Then, when the multi-axis manipulator resets at the CCD recognition station, it resets to the coordinate (0, 0, 0). When performing the first moving measurement, the local length a of the mobile phone is 8 cm; when performing the second moving measurement, the local width measurement a' of the mobile phone is 4 cm; when performing the third moving measurement, the local length b of the mobile phone is 8 cm; when performing the fourth moving measurement, the local width measurement b' of the mobile phone is 4 cm. Then, the length of the mobile phone can be calculated as a + b = 16 cm, and the width of the mobile phone is a' + b' = 8 cm.

[0121] In step S5 described above, the position of the alignment mechanism 610 is fixed, so the position of the second sensor group is fixed. As described in step S4, when the multi-axis manipulator moves to the positioning coordinate (0, 0, 0) of the CCD recognition station according to the set trajectory, the positioning rod should fall on the positioning coordinate (0, 0, 0). However, during the use of the device, due to collision or certain reasons, the positioning rod may have a slight deformation (position offset). The positioning rod should originally be a straight rod and be vertical at the positioning coordinate (0, 0, 0). Due to the position offset, when the multi-axis manipulator moves to the positioning coordinate (0, 0, 0) according to the specified trajectory, the positioning rod is not at the coordinate (0, 0, 0). Thus, if the multi-axis manipulator moves according to the specified trajectory at the detection station, the placement position of the mobile phone will be offset, resulting in inaccurate measurement data. Therefore, alignment needs to be performed through the alignment mechanism 610.

[0122] The position of the alignment mechanism 610 at the alignment station is fixed, and the second sensor group is fixed at the alignment station. It is set that when the positioning rod has no position offset and the multi-axis manipulator moves to the standard coordinate (30, 30, 30), the positioning rod triggers the second sensor group.

[0123] However, when the position of the positioning rod is offset and the multi-axis manipulator moves to the standard coordinate (30, 30, 30), the positioning rod has not yet triggered the second sensor group. Then, the multi-axis manipulator continues to move until the positioning rod triggers the second sensor group and then stops moving. It is set that the trigger coordinate at this time is (32, 32, 30). Then, it can be determined that the position of the positioning rod has shifted. If the multi-axis manipulator continues to move according to the set trajectory, then when moving to the detection station, there will be a deviation of +2 displacement in the position of the mobile phone at the detection station. After the above alignment, the moving trajectory of the multi-axis manipulator can be changed through the program to perform displacement compensation and cancel the +2 displacement deviation to ensure accurate measurement.

[0124] Optionally, the order of steps 4 and 5 above can be interchanged.

[0125] In the step S6, the detection time for the mobile phone to stay at the detection station is X, and X is set by the control system. Here, the measurement time can be set to 20 minutes. The measurement sensor measures the electric field value at the detection station and transmits the electric field value to the control system, and then calculates the SAR value.

[0126] A mobile phone can have multiple test states. For example: in a state of simple call, or in a state of connecting to a 4G network, or in a state of connecting to a 5G network, or in a state of connecting to a 5G network and in a call, or there are some other states. After writing the program / data through the USB automatic plugging and unplugging component, the various states of the mobile phone can be measured, and the radiation values of the mobile phone in different states can be calculated.

[0127] After a mobile phone test is completed, the multi-axis manipulator 200 resets and is ready to grab the next mobile phone for detection in the same way.
