[0002] A handheld terminal is a portable data processing terminal that features an operating system, memory, CPU, graphics card, output module, display module, data transmission and processing capabilities, and is portable and customizable. Generally, handheld terminals are divided into industrial-grade and consumer-grade handheld terminals. They play a significant role in both daily life and industrial production. They integrate a barcode scanning device with a data terminal, are battery-powered for offline operation, and possess real-time data acquisition, automatic storage, instant display, instant feedback, automatic processing, and automatic transmission functions. This ensures the authenticity, validity, timeliness, and availability of on-site data.
[0003] In the production process of handheld terminals, multiple performance tests need to be conducted before they leave the factory. Existing testing methods for handheld terminals based on the production line are generally divided into two types: one is testing by manual means, which is low in cost but low in efficiency and prone to errors in test results; the other is testing by mechanical equipment, which is more expensive, complex in structure, and large in size, making assembly and movement more troublesome. In addition, existing testing equipment only tests handheld terminals through one or two control axes, which is not precise or convenient enough for adjusting the position of the handheld terminal and the stylus. Summary of the Invention

[0014] According to the present invention, the carrier is disposed on the workbench, the carrier includes a base, an intermediate support member and a clamping member, the clamping member, the intermediate support member and the base are assembled from top to bottom, and the base is threadedly connected to the workbench.
[0015] According to the present invention, the clamping member is provided with a clamping groove, a light detection channel and a sound detection channel, and a plurality of clearance grooves, and the intermediate support member includes an NFC card sliding detection module.
[0016] According to the present invention, the upper bracket of the frame is provided with a light strip and a camera module. The electrical control module includes an electrical control box, which is detachably connected to the side wall of the partition located in the electrical control area.

[0018] According to a second aspect of the present invention, a control method for an automatic testing device for any of the above-described handheld terminals is provided, the control method comprising the following steps:
[0019] The system inputs a running signal to the main control board via a handle or keyboard. In response to the main control board's running signal, the third motor starts and drives the worktable to move along the second guide rail to the position to be tested. At this time, the first motor starts and drives the second control module to move along the first guide rail to the testing position. The second motor rotates forward and drives the threaded screw mechanism to move the touch module toward the position to be touched on the handheld terminal until the stylus completes one touch. At this time, the main control board collects the current test data and transmits it to the computer. The computer analyzes and stores the test data.
[0020] Continuing to respond to the operation signal, the handheld terminal performs a touch operation at the next position.

[0039] The following detailed description, in conjunction with the accompanying drawings, provides a further detailed description of an automatic testing device and control method for a handheld terminal according to the present invention. In this description, unless otherwise stated, the terms "upper," "lower," "left," "right," "inner," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are used only for the convenience of describing the present invention and simplifying the description. They are not intended to indicate or imply that the automatic testing device and control method for the handheld terminal must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.
[0040] Reference Figures 1-3 This invention provides an automatic testing device for a handheld terminal, comprising a frame 1 composed of several supports 101 and a cover plate 102. The internal space of the frame 1 is divided into a testing area 3 and an electronic control area 4 by a partition 2 and the supports 101. An electronic control module 5 is provided inside the electronic control area 4. The frame 1 includes a main frame 9 and an extension frame 10. The extension frame 10 is disposed on the side wall of the main frame 9. The upper end surface of the extension frame 10 and the side surface in contact with the main frame 9 and the extension frame 10 are both open surfaces. The cover plate 102 is fixedly connected to several supports 101. The bottom surfaces of the main frame 9 and the extension frame 10 are located on the same horizontal plane. A base plate 11 is laid on the bottom surface. A third control module 14 is disposed on the base plate 11.
[0041] In this embodiment of the invention, the bracket 101 is made of aluminum. The wall surface of the bracket 101 has a groove of equal length to the bracket 101, and the interior of the bracket 101 is hollow. The brackets 101 are fixedly connected by the following methods: first, by connecting two brackets 101 through angle iron placed inside the bracket 101; second, by connecting two brackets 101 through insertion holes; third, by connecting two brackets 101 through angle iron located outside the bracket 101. The first two connection methods facilitate sealing the outer surface of the bracket 101, ensuring aesthetics, while the third connection method improves structural stability.
[0042] Furthermore, provided that the cost and structural weight do not exceed the design limits, the material between them can be aluminum alloy.
[0043] Furthermore, bolt holes are provided on the outer wall of the bracket 101, which can also ensure the fixed installation of the equipment on the bracket 101.
[0044] Reference Figures 1-3 In this embodiment of the invention, the cover plate 102 is connected to each bracket 101 by a threaded connection, thereby allowing the side of the frame 1 to be closed. It should be noted that the upper surface of the outer frame 10 needs to be an open surface and cannot be closed by the cover plate 102. The side of the main frame 9 that contacts the outer frame 10 also needs to be an open surface. These two open surfaces can provide space for the installation between the handheld terminal 13 and the carrier 12. The internal space of the outer frame 1 is also a test space. The electrical control area 4 is the internal space after the bracket 101, the partition 2 and the cover plate 102 are combined. The side of the electrical control box 6 is positioned and fixed to the partition 2 by a quick-connect alignment mechanism 15. The lower end of the electrical control box 6 can be quickly positioned by cooperating with the groove. Then, the electrical control box 6 is fixedly installed in the electrical control area 4 by a threaded connection.
[0045] Reference Figures 4-8 The partition 2 is provided with a first control module 16 on the side wall of the test area 3, and a second control module 17 is provided on the first control module 16. The first control module 16 is used to realize the lateral movement of the second control module 17 on the first control module 16, and the second control module realizes the vertical up and down movement of the touch module, so as to perform movement operation on the relevant mechanism of the automatic test equipment. The bottom of the frame 1 is provided with a third control module 14 for changing the position of the handheld terminal 13. The partition 2 is provided with a first control module 16 on the side wall of the test area 3, and a second control module 17 is provided on the first control module 16. The first control module 16 is used to realize the lateral movement of the second control module 17 on the first control module 16, and the bottom of the frame 1 is provided with a third control module 14 for changing the position of the handheld terminal 13.
[0046] Reference Figure 4 , Figure 5 and Figure 7 The first control module 16 includes a first synchronous belt 19, a first guide rail 20, and a first motor 21. The second control module 17 is movably connected to the first guide rail 20 and is equipped with a touch module 23. The third control module 14 is equipped with a carrier 12 for mounting the handheld terminal 13. The first control module 16 also includes a first synchronous pulley 22. The second control module 17 moves laterally on the first guide rail 20 with the cooperation of the first synchronous pulley 22 and the first synchronous belt 19. The first synchronous pulley 22 and the first synchronous belt 19 have a precise transmission ratio, and the transmission is smooth with low noise, enabling the most accurate automated control. In the automatic testing equipment, the first synchronous belt 19 and the first synchronous pulley 22 can smoothly transmit the torque output by the first motor 21 to the second control module 17, so that the second control module 17 can move smoothly on the first track.
[0047] Reference Figure 4 and Figure 6 The second control module 17 also includes a second motor 24, a nut and screw mechanism 25, and a mounting plate 26 mounted on the nut and screw mechanism 25. The touch module 23 is fixedly installed on the side wall of the mounting plate 26. The nut and screw mechanism 25 is used to realize the reciprocating movement of the touch module 23 in the vertical direction. The nut and screw mechanism 25 is composed of a nut and a screw. When the screw rotates one revolution, the nut is displaced by one pitch. It is mainly used to convert rotational motion into linear motion or linear motion into rotational motion. After the second motor 24 is started, it drives the screw to rotate, thereby controlling the displacement of the nut and finally realizing the movement of the touch module 23. The forward / reverse rotation of the second motor 24 corresponds to controlling the downward / upward movement of the touch module 23.
[0048] Reference Figure 8 The third control module 14 includes a third motor 27, a second synchronous pulley 29, a second synchronous belt 28, a second guide rail 30, and a worktable 31. The second guide rail 30 is laid on the base plate 11. The worktable 31 is movably connected to the second guide rail 30 through several sliding rods. The second synchronous pulley 29 and the second synchronous belt 28 cooperate to transmit the torque output by the third motor 27 to the worktable 31 so as to realize the movement of the worktable 31 on the second guide rail 30. The second synchronous pulley 29 and the second synchronous belt 28 can smoothly transmit the torque output by the third motor 27 to the worktable 31, so that the worktable 31 can move smoothly on the second guide rail 30.
[0049] In this embodiment of the invention, reference is made to Figures 4-8The partition 2 is provided with a first limiting optical coupler 42, a second limiting optical coupler 32 and a third limiting optical coupler 18. There are two first limiting optical couplers 42. The two first displacement limiting optical couplers are respectively set at two extreme positions of the second control module 17 on the first guide rail 20. These two extreme positions are the extreme positions that the second control module 17 can reach at both ends of the first guide rail 20.
[0050] There are two second limiting optocouplers 32, which are respectively set at the two extreme positions that the touch module 23 can reach from the second control module 17. There are two third limiting optocouplers 18, which are respectively set at the two extreme positions that the worktable 31 can reach from the two ends of the second guide rail 30. The first limiting optocoupler 42, the second limiting optocoupler 32 and the third limiting optocoupler 18 respectively limit the movement range of the second control module 17, the touch module 23 and the worktable 31 to a certain area.
[0051] The electronic control module 5 controls the third control module 14 to move to the position to be detected. Under the control of the electronic control module 5, the first control module 16 drives the second control module 17 to move on the first guide rail 20 and stop at the set position. Under the control of the electronic control module 5, the second control module 17 drives the touch module 23 to move vertically until it touches the position to be touched on the handheld terminal 13.
[0052] Reference Figure 9 The carrier 12 is mounted on the workbench 31. The carrier 12 includes a base 33, an intermediate support 34, and a clamping member 35. The clamping member 35, the intermediate support 34, and the base 33 are assembled from top to bottom. The base 33 is threadedly connected to the workbench 31. The carrier 12 is composed of three modules: the clamping member 35, the intermediate support 34, and the base 33, which facilitates the installation, maintenance, and replacement of some parts of the carrier 12. The clamping member 35 has a clamping groove 36, a light detection channel 37, a sound detection channel 38, and several clearance grooves 39. The intermediate support 34 includes an NFC card sliding detection module.
[0053] Furthermore, the light detection channel 37 includes an entrance light hole and an exit light hole. The entrance light hole is located opposite to the light-emitting components such as the flash of the handheld terminal 13, and the exit light hole is located at the upper end of the clamping member 35 or other positions that facilitate light collection.
[0054] Furthermore, the sound inlet of the sound detection channel 38 is located at the sound outlet of the handheld terminal 13, and the sound outlet of the sound detection channel 38 is located at the sound receiving outlet of the handheld terminal 13. The sound outlet is generally the microphone of the handheld terminal 13, and the sound receiving outlet is generally the earpiece and microphone of the handheld terminal 13.
[0055] Furthermore, the sound detection channel 38 may include more than one sound outlet for detecting multiple sound receiving points.
[0056] Reference Figure 12 and Figure 13 The upper bracket 101 of the frame 1 is equipped with a light strip 40 and a camera module. The camera module is used to capture images of the handheld terminal 13 and the carrier 12, providing image information to the computer. The electronic control module 5 includes an electronic control box 6, which is detachably connected to the side wall of the partition 2 located in the electronic control area 4. The electronic control box 6 includes a quick-connect alignment component and a main control board. The quick-connect alignment component is used to achieve quick positioning of the electronic control box 6 and the partition 2. The frame 1 is also equipped with a handle 46, which is electrically connected to the main control board. The frame 1 is also equipped with a computer. The handle 46, in conjunction with the main control board, can control the operation of the first control module 16, the second control module 17, and the third control module 14 without the computer.
[0057] In this embodiment of the invention, the quick-connect alignment assembly includes a sleeve 7 disposed on the partition 2 and a sleeve rod 8 disposed on the electrical control box 6 corresponding to the sleeve 7. When the electrical control box 6 is installed, aligning the sleeve rod 8 with the sleeve 7 can limit the degrees of freedom of the electrical control box 6 in four directions, enabling the electrical control box 6 to be quickly positioned in the installation position. The number of sleeves 7 and sleeve rods 8 is at least two. The cooperation of a single sleeve 7 and sleeve rod 8 cannot completely limit the degrees of freedom of the electrical control box 6 in four directions, because the electrical control box 6 may rotate.
[0058] Furthermore, the sleeve 7 can be installed on the electrical control box 6, and the sleeve rod 8 can be installed on the partition plate 2.
[0059] The touch module 23 includes a stylus 45 and a touch box 40 for loading the stylus 45. The touch box 40 is provided with a pressure feedback component 41 for reducing the impact force caused by the stylus.
[0060] In this embodiment of the invention, the pressure feedback component 41 consists of several springs. The touch box 40 has a guide block 43 with an internal moving channel, and both ends of the touch box 40 are covered with caps 44. The stylus 45 is placed in the moving channel of the guide block 43 and passes through one end of the guide block 43 and one end of the cap 44 of the touch box 40. The other end of the guide block 43 is closed, and several storage slots are opened on the end face of this end. Several springs are placed into the storage slots one by one, and the length of the springs needs to exceed the depth of the storage slots. When the stylus 45 touches the mobile terminal, the feedback force received by the stylus 45 causes the guide block 43 to move inside the touch box 40. At this time, the springs abut against the other end of the cap 44 of the touch box 40, so that the impact force on the handheld terminal 13 and the stylus 45 is reduced.
[0061] Furthermore, the pressure feedback component 41 can also be any elastic element other than the spring.
[0062] Accordingly, based on the automatic testing equipment for the handheld terminal 13 proposed in this embodiment of the invention, this embodiment of the invention also proposes a control method, which is applied to the main control board and the computer, for controlling the automatic testing equipment for the handheld terminal 13 proposed in this embodiment of the invention:
[0063] The main control board receives a running signal via the handle 46 or keyboard. In response to the main control board's running signal, the third motor 27 starts and drives the workbench 31 to move along the second guide rail 30 to the position to be tested. At this time, the first motor 21 starts and drives the second control module 17 to move along the first guide rail 20 to the testing position. The second motor 24 starts rotating forward and drives the threaded screw mechanism to move the touch module 23 toward the position to be touched on the handheld terminal 13 until the stylus 45 completes a touch. At this time, the main control board collects the current test data and transmits it to the computer. The computer analyzes and stores the test data.
[0064] Continuing to respond to the operation signal, the handheld terminal 13 performs a touch operation at the next position. The second motor 24 reverses and drives the screw mechanism to move the touch module 23 away from the previously touched position. The third motor 27 reverses / forwards and drives the worktable 31 to the set position. The first motor 21 forwards / reverses and drives the second control module 17 to the set position. The second motor 24 forwards and drives the screw mechanism to move the touch module 23 toward the new touch position of the handheld terminal 13 until the stylus 45 completes a touch. The test item of the handheld terminal responds to the touch action. The handheld terminal responds to the test signal of the test item, and the touch module triggers the relevant execution actions one by one. The handheld terminal responds to the actions one by one. The signals, for example: 1. Upon entering the screen color recognition test, the screen displays different RGB full colors to provide images for the top camera module to capture for computer recognition algorithms; 2. Upon entering the button function test, buttons are pressed via the touch module, and the handheld terminal's button detection program provides feedback. The test results are then sent to the computer via the handheld terminal's USB, and the result of whether the test passed or failed is recorded; 3. Upon entering the audio test, the handheld terminal's speaker emits a special test tone, the handheld terminal's microphone receives the test tone, and the test software records the microphone's audio file. This file is then uploaded to the computer via the handheld terminal's USB, where the computer's algorithm software compares the audio file and the recorded audio file to determine if the speaker or microphone is functioning correctly. Finally, after all tests are completed, the computer summarizes all test results and feeds them back to the upper-level database system for production management.
[0065] After the test is completed, the first motor 21, the second motor 24 and the third motor 27 all respond to the reverse signal and start, driving the second control module 17, the touch module 23 and the worktable 31 back to their initial positions respectively.
[0066] In this embodiment of the invention, the functions of the main control board and the computer are as follows:
[0067] The main functions of the computer are: to interact with the main control board and to run the test software.
[0068] The main function of the main control board is as follows: according to the instructions of the main control board, the first motor 21, the second motor 24, and the third motor 27 will respond and start running. The control instructions issued by the main control board to the first motor 21 are mainly for the first motor 21 to perform the following operations:
[0069] When the main control board sends a test signal to the first motor 21, the first motor 21 responds to the test signal and starts in the forward direction, thereby causing the first motor 21 to drive the second control module 17 to move the first guide rail 20 by a corresponding number of steps. When the next test is carried out, the first motor 21 rotates forward / reverse, causing the second control module 17 to move to the next position.
[0070] The control commands issued by the main control board to the second motor 24 are mainly for the second motor 24 to perform the following operations:
[0071] When the main control board sends a test signal to the second motor 24, the second motor 24 responds to the test signal and starts in the forward direction, driving the touch module 23 to move to the required position and touch the test point of the handheld terminal 13. After the touch is completed, the second motor 24 reverses and the touch module 23 rises, ready for the start of the next test.
[0072] The control commands issued by the main control board to the third motor 27 are mainly for the third motor 27 to perform the following operations:
[0073] When the main control board sends a test signal to the third motor 27, the third motor 27 starts in the forward direction in response to the test signal, driving the worktable 31 to move to the set position on the second track. When the test is completed, the third motor 27 rotates forward / reverse / stops, so that the worktable 31 moves to the required position or stays in the current position.
[0074] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be considered within the scope of protection of the present invention.

7. The control method for the automatic testing equipment according to any one of claims 1-6, applied to a main control board and a computer, characterized in that, The control method includes: The system inputs a running signal to the main control board via a handle or keyboard. In response to the running signal from the main control board, the third motor starts and drives the worktable to move along the second guide rail to the position to be tested. At this time, the first motor starts and drives the second control module to move along the first guide rail to the testing position. The second motor rotates forward and drives the threaded screw mechanism to move the touch module toward the position to be touched on the handheld terminal until the stylus completes a touch. The item to be tested on the handheld terminal responds to the touch action. The handheld terminal responds to the test signal of the item to be tested. The touch module triggers the relevant execution actions one by one, and the handheld terminal responds to the action signals one by one. Continuing to respond to the operation signal, the handheld terminal performs a touch operation at the next position. The second motor reverses and drives the screw mechanism to move the touch module away from the previously touched position. The third motor reverses / forwards and drives the worktable to the set position. The first motor forwards / reverses and drives the second control module to the set position. The second motor forwards and drives the screw mechanism to move the touch module toward the new touch position of the handheld terminal until the stylus completes another touch. At this time, the main control board collects the current test data and transmits it to the computer. The computer analyzes and stores the test data. According to this operation logic, the first control module, the second control module, and the third control module cooperate to ensure that the stylus touches all the test positions of the handheld terminal. After the test is completed, the first motor, the second motor and the third motor all respond to the reverse signal and start, driving the second control module, the touch module and the worktable back to their initial positions respectively.
