Description

[0002] With the rapid development of information technology, mobile phones have become an indispensable communication tool in people's daily lives, and the scale of mobile phone manufacturing has become enormous. During the manufacturing process, mobile phones undergo comprehensive testing of all functions before leaving the factory; only products that pass these tests are considered qualified.

[0003] Mobile phone testing involves numerous components, but existing testing equipment typically only tests a single function, such as proximity sensors or fingerprint recognition. To complete full functionality testing, the phone must be moved sequentially into multiple independent devices for testing. Clearly, existing mobile phone testing equipment lacks comprehensive functionality, requiring multiple devices to complete functional testing, resulting in a large footprint. Furthermore, transferring the phone between devices inevitably increases clamping and transfer time, leading to low overall testing efficiency. Therefore, there is an urgent need for automated equipment capable of performing multi-functional mobile phone testing. Summary of the Invention

[0021] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0022] like Figures 1 to 17As shown, a mobile phone functional testing pipeline includes a controller, a first machine 1000, and a second machine 2000. The controller can be an industrial computer, a programmable logic controller, or other electronic devices with data processing and control functions, used to coordinate and control the operation of the entire equipment. The first machine 1000 is equipped with a first conveyor belt 100, and the second machine 2000 is equipped with a second conveyor belt 200. The end of the first conveyor belt 100 is connected to the beginning of the second conveyor belt 200, thus connecting the first machine 1000 and the second machine 2000 in series to form a complete testing pipeline. The first conveyor belt 100 is used to transport mobile phones on the first machine 1000, and the second conveyor belt 200 is used to transport mobile phones on the second machine 2000. The mobile phone can be directly transferred from the end of the first conveyor belt 100 to the beginning of the second conveyor belt 200, realizing continuous pipeline testing.

[0023] In this embodiment, there are two first conveyor belts 100 and two second conveyor belts 200, with the two first conveyor belts 100 parallel to each other, and the beginning ends of the two second conveyor belts 200 connected to the end ends of the corresponding first conveyor belts 100. Setting up two parallel conveyor belts allows two mobile phones to be tested simultaneously, thereby improving testing efficiency.

[0024] The first testing station 1000 is equipped with a first scanning mechanism 110, a first testing station 300, a second testing station 400, a third testing station 500, a fourth testing station 600, a fifth testing station 700, and a sixth testing station 730, arranged sequentially along the conveying direction of the first conveyor belt 100. The first conveyor belt 100 can sequentially transport mobile phones to the above-mentioned stations, allowing the mobile phones to complete various tests in sequence. The first scanning mechanism 110 is used to scan the identification code on the mobile phone, read the mobile phone's identity information, and establish a wireless communication connection with the controller. The first testing station 300 is equipped with a first distance sensing test module 310, a first charging test module 320, and a microphone test module, which are used to test the mobile phone's distance sensor, charging function, and microphone pickup function, respectively. The second testing station 400 is equipped with a first light sensing test module 410, a gyroscope test module 420, and a first NFC test module 430, which are used to test the mobile phone's light sensor, gyroscope, and NFC functions, respectively. The third testing station 500 is equipped with a button testing module 510 and a first fingerprint testing module 520, used to test the side buttons and in-screen fingerprint recognition functions of the phone, respectively. The fourth testing station 600 is equipped with a vibration testing module and a second fingerprint testing module 610, used to test the phone's vibration motor and re-verify the in-screen fingerprint recognition function, respectively. The fifth testing station 700 is equipped with a screen testing module 710 and an infrared testing module, used to test the phone's screen display and infrared emission functions, respectively. The sixth testing station 730 is equipped with a second NFC testing module, used to re-test the phone's NFC function from the perspective of a card reader.

[0025] The first machine station 1000 is also equipped with a first defective product conveyor belt 3000 and a first defective product gripping mechanism 840. The first defective product gripping mechanism 840 is connected to the first defective product conveyor belt 3000 and the sixth testing station 730, respectively. It is used to grip the mobile phones that are judged to be defective in the first machine station 1000 test from the sixth testing station 730 and place them on the first defective product conveyor belt 3000 for delivery. The first defective product conveyor belt 3000 can deliver the defective mobile phones out of the first machine station 1000 for unified processing.

[0026] The second machine station 2000 is equipped with a second scanning mechanism 120, a seventh testing station 800, an eighth testing station 130, a ninth testing station 900, a tenth testing station 140, an eleventh testing station 150, and a defective product picking station 160, arranged sequentially along the conveying direction of the second conveyor belt 200. The second conveyor belt 200 can sequentially transport mobile phones to the aforementioned stations. The second scanning mechanism 120 is used to scan the mobile phone identification code again to confirm identity information and maintain wireless communication. The seventh testing station 800 is equipped with a first earphone testing module 810, a second charging testing module 820, and a flash testing module 830, used to test the mobile phone's earphone jack, charging function, and flash, respectively. The eighth testing station 130 is equipped with a second distance sensor testing module, used to test the distance sensor again. The ninth testing station 900 is equipped with a side fingerprint testing module 910 and a second light sensor testing module 920, used to test the mobile phone's side fingerprint sensor and light sensor, respectively. The tenth test station 140 is equipped with a second earphone test module and a third fingerprint test module, used to retest the earphone and in-screen fingerprint recognition, respectively. The eleventh test station 150 is equipped with a speaker test module, used to test the phone's speaker audio playback function.

[0027] The second machine 2000 is also equipped with a second defective product conveyor belt 4000 and a second defective product gripping mechanism 170. The second defective product gripping mechanism 170 is connected to the second defective product conveyor belt 4000 and the defective product gripping station 160, respectively. It is used to grip the mobile phones that are judged to be defective in the second machine 2000 test from the defective product gripping station 160 and place them on the second defective product conveyor belt 4000 for delivery. The second defective product conveyor belt 4000 can deliver the defective mobile phones out of the second machine 2000 for unified processing.

[0028] With the above layout, the first testing station 1000 and the second testing station 2000 are connected in series, distributing multiple functions of the mobile phone across the two stations. Each station independently transports the phone, enabling dual-channel parallel testing. Two phones can undergo different stages of testing simultaneously on the two stations, significantly improving testing efficiency. Furthermore, all test items are integrated into a single production line, eliminating the need to transfer phones between multiple independent devices, reducing equipment footprint and manual operation.

[0029] like Figure 4 As shown, the second conveyor belt 200 includes a first conveyor frame 210 and a second conveyor frame 220 that are parallel to each other. The second conveyor frame 220 is fixedly installed on the second machine base 2000. Both the first conveyor frame 210 and the second conveyor frame 220 are equipped with a conveyor belt 230 and a conveyor drive mechanism 240. The output end of the conveyor drive mechanism 240 is connected to the conveyor belt 230, and the conveyor drive mechanism 240 can drive the conveyor belt 230 to rotate on the conveyor frame. The conveyor belt 230 can be any type of belt conveyor structure capable of carrying and conveying mobile phones, such as a synchronous belt, a flat belt, or a chain. The conveyor drive mechanism 240 can be a device or structure capable of driving the synchronous belt to move, such as a motor pulley structure or a motor gear structure.

[0030] During operation, the two ends of the mobile phone are placed on two conveyor belts 230, which together carry and transport the phone. Two conveyor drive mechanisms 240 simultaneously drive the two conveyor belts 230, thus moving the phone from one workstation to the next. Because the phone is placed on both conveyor belts 230, the synchronized movement of the two belts ensures that the phone maintains a stable posture during transport, preventing tilting or shifting.

[0031] The second machine tool 2000 is equipped with a conveying adjustment mechanism 250. The output end of the conveying adjustment mechanism 250 is connected to the first conveyor frame 210, which is used to drive the first conveyor frame 210 to slide laterally on the machine tool, thereby adjusting the distance between the first conveyor frame 210 and the second conveyor frame 220, and thus changing the distance between the two conveyor belts 230. The conveying adjustment mechanism 250 can be any linear drive module such as a motor screw module or a motor pulley module. Different mobile phone models have different lengths. By adjusting the distance between the first conveyor frame 210 and the second conveyor frame 220 through the conveying adjustment mechanism 250, the distance between the two conveyor belts 230 can be changed, so that mobile phones of different lengths can be stably placed on the two conveyor belts 230 for conveying and testing, improving the versatility and adaptability of the equipment. The conveying adjustment mechanism 250 can be any linear drive module such as a motor screw module or a motor pulley module.

[0032] The structure and working principle of the first conveyor belt 100 are the same as those of the second conveyor belt 200; therefore, the specific structure of the first conveyor belt 100 will not be described in detail here.

[0033] The first scanning mechanism 110 is located at the beginning of the first conveyor belt 100 and is used to scan mobile phones on the first conveyor belt 100. The second scanning mechanism 120 is located at the beginning of the second conveyor belt 200 and is used to scan mobile phones on the second conveyor belt 200. Both the first scanning mechanism 110 and the second scanning mechanism 120 can be any scanning device capable of identifying mobile phone identification information, such as a barcode scanner or a QR code scanner. The function of the scanning mechanism is to read the identification code on the mobile phone, such as the IMEI code, serial number, or QR code, thereby establishing a communication connection between the mobile phone and the controller. After the communication connection is established, the controller can send test commands to the mobile phone and receive test feedback data from the mobile phone, realizing automated test control of the mobile phone. After scanning is completed, the mobile phone is recognized by the controller and included in the test management system.

[0034] On the first machine tool 1000, a first lifting and blocking mechanism 180 is provided at the corresponding positions of the first testing station 300, the second testing station 400, the third testing station 500, the fourth testing station 600, and the fifth testing station 700. Similarly, on the second machine tool 2000, a second lifting and blocking mechanism 190 is provided at the corresponding positions of the seventh testing station 800, the eighth testing station 130, the ninth testing station 900, the tenth testing station 140, and the eleventh testing station 150. The function of the first lifting and blocking mechanism 180 and the second lifting and blocking mechanism 190 is to block and limit the mobile phone at the corresponding processing position and to lift the mobile phone above the conveyor belt for accurate testing.

[0035] like Figure 5As shown, the first lifting and blocking mechanism 180 includes a lifting fixed base 181, which is fixedly installed on the first machine base 1000. A blocking cylinder 182 and a lifting cylinder 183 are provided on the lifting fixed base 181. The blocking cylinder 182 is vertically installed, with its output end extending upwards and connected to a blocking block 184. When the piston rod of the blocking cylinder 182 extends, the blocking block 184 moves upwards and extends above the first conveyor belt 100. When the piston rod of the blocking cylinder 182 retracts, the blocking block 184 moves downwards and retracts below the first conveyor belt 100. The lifting cylinder 183 is vertically installed, with its output end extending upwards and connected to a mobile phone tray 185, which is used to support mobile phones. When the piston rod of the lifting cylinder 183 extends, the phone holder 185 moves upward and extends above the first conveyor belt 100, lifting the phone on the first conveyor belt 100 to a preset test height. When the piston rod of the lifting cylinder 183 retracts, the phone holder 185 moves downward and retracts below the first conveyor belt 100, placing the phone back onto the first conveyor belt 100. A positioning clamping cylinder 186 is also installed on the phone holder 185. The positioning clamping cylinder 186 is horizontally arranged, and its output end is connected to a phone positioning clamping block 187. The positioning clamping cylinder 186 can drive the phone positioning clamping block 187 to move horizontally, bringing it closer to or away from the blocking block 184, thereby cooperating with the blocking block 184 to clamp and fix the phone from both sides.

[0036] During processing, the blocking cylinder 182 activates first, driving the blocking block 184 to extend upwards above the first conveyor belt 100. The first conveyor belt 100 transports the phone forward along the conveying direction. When the phone contacts the blocking block 184, the blocking block 184 stops the phone, keeping it in the correct position at the corresponding test station. Then, the lifting cylinder 183 activates, driving the phone holder 185 to move upwards, lifting the phone from the first conveyor belt 100 and raising it to the preset test height. Next, the positioning clamping cylinder 186 activates, driving the phone positioning clamp 187 to move closer to the blocking block 184 until the phone positioning clamp 187 abuts against the side of the phone furthest from the blocking block 184. At this point, both sides of the phone are clamped and fixed by the blocking block 184 and the phone positioning clamp 187 respectively, and the phone is stably positioned in the preset test position, preventing displacement during subsequent testing. After the phone is clamped and fixed, the various test modules at this test station begin testing the phone.

[0037] The second lifting blocking mechanism 190 has the same mechanism as the first lifting blocking mechanism 180; therefore, the specific structure of the second lifting blocking mechanism 190 will not be described in detail here.

[0038] like Figure 6As shown, the first distance sensing test module 310 includes a distance sensing mounting base 311, a distance sensing lifting assembly 312, and a distance sensing test gray card 313. The distance sensing mounting base 311 is fixedly mounted on the first machine tool 1000, and the distance sensing lifting assembly 312 is mounted on the distance sensing mounting base 311. The distance sensing lifting assembly 312 can be a motor screw module, a motor synchronous belt module, or other modules capable of linear drive. The distance sensing test gray card 313 is mounted on the output end of the distance sensing lifting assembly 312. The distance sensing test gray card 313 is a gray card with standard reflectivity, used to simulate obstacles or objects in front of the mobile phone during use. During testing, the distance sensing lifting assembly 312 drives the distance sensing test gray card 313 downwards, causing it to descend to a preset position. At this point, the distance between the distance sensing test gray card 313 and the mobile phone reaches the preset test distance. The proximity sensor on the mobile phone emits infrared light or laser light. When this light encounters the proximity test gray card 313, it is reflected back. The proximity sensor receives the reflected light and calculates the distance between itself and the gray card 313. The mobile phone wirelessly transmits the distance data detected by the proximity sensor to the controller. The controller compares this data with a preset standard distance. If the deviation is within the allowable range, the proximity sensor is deemed qualified; otherwise, it is deemed unqualified.

[0039] The structure and working principle of the second distance sensing test module are the same as those of the first distance sensing test module 310; therefore, the specific structure of the second distance sensing test module will not be described in detail here.

[0040] like Figure 6 As shown, the first charging test module 320 includes a charging mounting base 321, a charging insertion cylinder 322, and a charging plug 323. The charging mounting base 321 is fixedly installed on the conveyor frame of the first machine tool 1000 or the first conveyor belt 100. The charging insertion cylinder 322 is installed on the charging mounting base 321, and the charging plug 323 is connected to the output end of the charging insertion cylinder 322. The charging plug 323 is electrically connected to the controller via a wire. The controller can provide charging voltage and current to the mobile phone through the charging plug 323 and detect the current and voltage parameters during the charging process. When the mobile phone is transported to the first test station 300 and clamped and fixed by the first lifting and blocking mechanism 180, the charging insertion cylinder 322 is activated, driving the charging plug 323 to move closer to the mobile phone, so that the charging plug 323 is inserted into the charging interface of the mobile phone. The controller supplies power to the mobile phone through the charging plug 323 and detects whether the charging current and voltage are normal. At the same time, the mobile phone also sends its charging status information to the controller via wireless communication. The controller comprehensively judges whether the charging function of the mobile phone is normal. After the test is completed, the charging plug cylinder 322 reverses its movement, pulling the charging plug 323 out of the phone's charging port.

[0041] The structure and working principle of the second charging test module 820 are the same as those of the first charging test module 320; therefore, the specific structure of the second charging test module 820 will not be described in detail here.

[0042] like Figure 6 As shown, the sound pickup test module includes a speaker 330, which is fixedly installed on the first machine platform 1000 and located below the first lifting and blocking mechanism 180 corresponding to the first test station 300. When the mobile phone is transported to the first test station 300 and lifted to the test height by the first lifting and blocking mechanism 180, the speaker 330 is positioned directly below the mobile phone. During the sound pickup test, the controller controls the speaker 330 to play a preset audio signal, and the microphone on the mobile phone picks up the sound played by the speaker 330. The mobile phone then transmits the audio data collected by the microphone to the controller via wireless communication. The controller analyzes the received audio data to determine whether the sound intensity, clarity, and other indicators meet the requirements, thereby determining whether the mobile phone's sound pickup function is normal.

[0043] After the mobile phone completes the distance sensing test, charging test, and sound pickup test at the first testing station 300, the positioning clamping cylinder 186 retracts, driving the mobile phone positioning clamp 187 to move away from the side wall of the mobile phone, releasing the clamp on the mobile phone. Then, the lifting cylinder 183 retracts, driving the mobile phone tray 185 to descend and place the mobile phone back onto the first conveyor belt 100. Next, the blocking cylinder 182 retracts, driving the blocking block 184 to descend and retract below the first conveyor belt 100. The first conveyor belt 100 continues to move, transporting the mobile phone to the second testing station 400.

[0044] like Figure 7 , Figure 8As shown, the gyroscope testing module 420 includes a horizontal fixing frame 421, a horizontal clamping cylinder 422, and a horizontal clamping block 423. The horizontal fixing frame 421 is fixedly mounted on the first machine base 1000. A horizontal mounting surface 424 is provided on the horizontal fixing frame 421. The horizontal mounting surface 424 is a horizontal surface with high-precision flatness, used to provide a horizontal reference for the mobile phone. Horizontal clamping cylinders 422 are respectively provided on the left and right sides of the horizontal mounting surface 424. The horizontal clamping cylinders 422 are arranged horizontally, and the horizontal clamping blocks 423 are connected to their output ends. The horizontal clamping blocks 423 are slidably engaged with the horizontal mounting surface 424, so that the horizontal clamping blocks 423 can slide smoothly along the horizontal mounting surface 424 under the drive of the horizontal clamping cylinders 422. When the mobile phone is conveyed to the second testing station 400 and lifted to the height of the horizontal clamping block 423 by the first lifting and blocking mechanism 180, the two horizontal clamping cylinders 422 act simultaneously, driving the two horizontal clamping blocks 423 to move closer to the mobile phone until the two horizontal clamping blocks 423 abut against the mobile phone from the left and right sides respectively, horizontally clamping and fixing the mobile phone. Since the horizontal clamping blocks 423 slide along the horizontal mounting surface 424, and the horizontal mounting surface 424 itself is horizontal, the clamped mobile phone is also forced to remain in a horizontal state. While the mobile phone is in a horizontal state, the controller sends gyroscope calibration and test commands to the mobile phone via wireless communication. The gyroscope inside the mobile phone is calibrated in a horizontal state and sends the calibration data to the controller. The controller determines whether the gyroscope is working properly based on the calibration data.

[0045] like Figure 7 As shown, the first light-sensing test module 410 includes a light-shielding mounting bracket 411, a light source mounting base 412, and a surface light source 413. The light-shielding mounting bracket 411 is fixedly mounted on the first machine base 1000. A light shield 414 is mounted on the light-shielding mounting bracket 411, which surrounds the entire gyroscope test module 420 and the mobile phone clamping position, forming a closed dark environment that reduces the entry of ambient light. The light source mounting base 412 is mounted on the first machine base 1000, and the surface light source 413 is mounted on the light source mounting base 412. The surface light source 413 is located directly above the horizontal mounting surface 424. When the mobile phone is clamped and fixed by the horizontal clamping block 423, the mobile phone is located directly below the surface light source 413. During light-sensing testing, the surface light source 413 emits uniform light that illuminates the mobile phone's light sensor. The mobile phone's light sensor detects the light intensity and transmits the detection data to the controller via wireless communication. The controller compares the detected data with the preset standard illumination value to determine whether the light sensor is working properly.

[0046] like Figure 7As shown, the first NFC test module 430 includes an NFC lifting cylinder 431, an NFC rotating cylinder 432, and an NFC chip 433. The NFC lifting cylinder 431 is fixedly mounted on the light-shielding mounting bracket 411, the NFC rotating cylinder 432 is mounted on the output end of the NFC lifting cylinder 431, and the NFC chip 433 is mounted on the output end of the NFC rotating cylinder 432. When NFC testing is required, the NFC lifting cylinder 431 extends, pushing the NFC rotating cylinder 432 and the NFC chip 433 downwards to the height of the mobile phone. Then, the NFC rotating cylinder 432 rotates, rotating the NFC chip 433 to a position directly above the mobile phone inside the light-shielding cover 414. At this time, the NFC antenna on the mobile phone can sense the radio frequency signal emitted by the NFC chip 433. The mobile phone sends the NFC test result to the controller via wireless communication, and the controller determines whether the mobile phone's NFC function is normal based on this result. After the NFC test is completed, the NFC rotary cylinder 432 rotates in the opposite direction, moving the NFC chip 433 from the inside of the light shield 414 to the outside, thus moving it away from directly above the phone and achieving a rotational positioning to facilitate the light-sensing test. Then, the NFC lifting cylinder 431 retracts, raising the NFC rotary cylinder 432 and the NFC chip 433 back to their initial positions. Through the combined movement of the NFC lifting cylinder 431 and the NFC rotary cylinder 432, the NFC chip 433 can flexibly switch between the test position and the positioning position, ensuring the smooth progress of the NFC test while avoiding interference with the light-sensing test.

[0047] After the mobile phone completes the gyroscope test, light sensor test and NFC test at the second test station 400, the first lifting and blocking mechanism 180 puts the mobile phone back onto the first conveyor belt 100, and the first conveyor belt 100 transports the mobile phone to the third test station 500.

[0048] like Figure 9As shown, the button testing module 510 includes a button testing fixture 511, a pressing block mounting frame 512, a pressing head mounting frame 513, a pressing test cylinder 514, and a test pressing head 515. The button testing fixture 511 is fixedly mounted on the first machine base 1000, and the pressing block mounting frame 512 is mounted on the button testing fixture 511. The pressing block mounting frame 512 is a hollow frame structure. When the mobile phone is lifted by the first lifting blocking mechanism 180, the mobile phone is located inside the pressing block mounting frame 512. Pressing head mounting frames 513 are respectively provided on the left and right sides of the pressing block mounting frame 512. The pressing head mounting frames 513 and the pressing block mounting frame 512 are connected by an elongated slot and screws to achieve an adjustable limiting connection. By loosening the screws, the position of the pressing head mounting frames 513 can be adjusted along the direction of the elongated slot to adapt to the differences in button positions on different mobile phone models. Each press head mounting base 513 is equipped with a press test cylinder 514, and a test press head 515 is mounted on the output end of the press test cylinder 514. During testing, the press test cylinder 514 extends, driving the test press head 515 to move closer to the phone until the test press head 515 comes into contact with the button on the side of the phone and performs a pressing action. After the phone detects that the button has been pressed, it generates a corresponding electrical signal. The phone sends this signal to the controller via wireless communication, and the controller determines whether the button function is normal based on the received signal. After the test is completed, the press test cylinder 514 retracts, driving the test press head 515 away from the phone.

[0049] like Figure 9 , Figure 10As shown, the first fingerprint testing module 520 includes a fingerprint testing mounting block 521 and a pressure head assembly. The fingerprint testing mounting block 521 is fixedly mounted on the button testing mounting base 511, providing the mounting foundation for the entire fingerprint testing module. A lifting cylinder 522 is mounted on the fingerprint testing mounting block 521, and a lifting slider 523 is connected to the output end of the lifting cylinder 522. The pressure head assembly includes a vertically arranged pressing guide rail 524, a counterweight 525, a pressing limit block 526, a pressure head mounting base 527, a pressure sensor 528, and a fingerprint testing head 529. The pressing guide rail 524 is vertically arranged and slidably engaged with the lifting slider 523, allowing the pressing guide rail 524 to slide freely relative to the lifting slider 523 in the vertical direction. Multiple detachable counterweights 525 are provided at the upper end of the pressure guide rail 524. The counterweights 525 are fitted onto the upper end of the pressure guide rail 524. By increasing or decreasing the number of counterweights 525, the total weight of the entire pressure guide rail 524 and its associated components can be adjusted, thereby adjusting the pressure of the fingerprint sensor 529 on the mobile phone. A pressure limiting block 526 is provided on the pressure guide rail 524. The pressure limiting block 526 protrudes outward. When the lifting slider 523 is located below the pressure limiting block 526, the pressure limiting block 526 can abut against the upper end surface of the lifting slider 523, thereby suspending the pressure guide rail 524 on the lifting slider 523. A pressure head mounting seat 527 is installed at the lower end of the pressure guide rail 524. A pressure sensor 528 is installed on the pressure head mounting seat 527. The detection end of the pressure sensor 528 faces downward and is fitted with the fingerprint sensor 529.

[0050] After the phone is clamped and fixed by the lifting blocking mechanism, it is positioned directly below the fingerprint test head 529. At this time, the downward limiting block 526 abuts against the upper end of the lifting slider 523, and the downward guide rail 524 is suspended in the air by the lifting slider 523. During fingerprint testing, the piston rod of the lifting cylinder 522 extends, driving the lifting slider 523 to move downward. The lifting slider 523 moves away from the downward limiting block 526, and the downward guide rail 524, losing its support, descends freely under gravity until the fingerprint test head 529 abuts against the fingerprint recognition area on the phone screen. The fingerprint recognition area on the phone screen scans and recognizes the fingerprint test head 529, and the phone sends the recognition result to the controller via wireless communication. The controller determines whether the fingerprint recognition function is normal. During the fingerprint test, the pressure sensor 528 detects the pressure value of the fingerprint test head 529 on the phone in real time and sends the pressure data to the controller to ensure that the pressure value is within the preset allowable range. By increasing or decreasing the number of counterweights 525, the total weight of the pressure guide rail 524 can be adjusted, thereby adjusting the pressure of the fingerprint test head 529 on the mobile phone to meet different test pressure requirements. After the test is completed, the piston rod of the lifting cylinder 522 retracts, driving the lifting slider 523 to move upward. When the lifting slider 523 abuts against the pressure limit block 526, the lifting slider 523 drives the entire pressure guide rail 524 to rise synchronously through the pressure limit block 526, causing the fingerprint test head 529 to leave the surface of the mobile phone until it returns to its initial position.

[0051] The structures of the second fingerprint testing module 610 and the third fingerprint testing module are exactly the same as those of the first fingerprint testing module 520. Therefore, the specific structures of the second fingerprint testing module 610 and the third fingerprint testing module will not be described in detail here.

[0052] After the phone completes button and fingerprint tests at the third testing station 500, the first lifting and blocking mechanism 180 places the phone back onto the first conveyor belt 100, which then transports the phone to the fourth testing station 600.

[0053] like Figure 9As shown, a vibration testing module and a second fingerprint testing module 610 are installed on the fourth testing station 600. The vibration testing module includes a vibration sensor (not shown in the figure), which is fixedly installed on the output end of the positioning clamping cylinder 186 of the first lifting and blocking mechanism 180 corresponding to the fourth testing station 600, arranged side by side with the mobile phone positioning clamp 187. When the mobile phone is transported to the fourth testing station 600, the first lifting and blocking mechanism 180 is activated, clamping and fixing the mobile phone and lifting it to a preset testing height. When the positioning clamping cylinder 186 drives the mobile phone positioning clamp 187 to move towards the blocking block 184, the vibration sensor also moves synchronously towards the mobile phone. When the mobile phone positioning clamp 187 abuts against one side of the mobile phone and clamps and fixes the mobile phone, the vibration sensor also abuts tightly against the side wall of the mobile phone. At this time, the controller sends a vibration command to the mobile phone through wireless communication, controlling the mobile phone's vibration motor to start working. When the mobile phone vibrates, the vibration sensor collects parameters such as the vibration amplitude and frequency of the mobile phone and transmits the collected data to the controller. The controller analyzes the vibration data to determine whether the vibration motor can start normally and whether the vibration parameters meet the design requirements.

[0054] The phone also underwent fingerprint testing at the fourth testing station 600 to verify the repeatability and stability of the phone's fingerprint recognition function.

[0055] After the mobile phone completes the vibration test and fingerprint test at the fourth test station 600, the first lifting and blocking mechanism 180 puts the mobile phone back onto the first conveyor belt 100, and the first conveyor belt 100 transports the mobile phone to the fifth test station 700.

[0056] like Figure 11 As shown, the screen testing module 710 includes a camera mounting bracket 711 and a test camera 712. The camera mounting bracket 711 is fixedly mounted on the first machine base 1000, and the test camera 712 is fixedly mounted on the camera mounting bracket 711, located directly above the mobile phone on the first lifting and blocking mechanism 180. When the mobile phone is clamped and fixed by the first lifting and blocking mechanism 180, the lens of the test camera 712 faces the screen of the mobile phone. During screen testing, the controller sends a screen-on command to the mobile phone via wireless communication, causing the mobile phone screen to display a preset test image. The test image can be a solid color image, a grayscale image, a colored stripe image, or other standard images that can detect screen display defects. The test camera 712 takes a picture of the mobile phone screen and transmits the captured image to the controller. The controller analyzes the captured image using an image processing algorithm to detect whether the screen has defects such as dead pixels, bright spots, dark spots, color differences, uneven brightness, and display abnormalities, thereby determining whether the screen display function is qualified.

[0057] The infrared testing module includes an infrared receiver 720, which is fixedly mounted on the first platform 1000 and located to one side of the first lifting and blocking mechanism 180. When the mobile phone is clamped and fixed by the first lifting and blocking mechanism 180, the infrared transmitter on the mobile phone is directly facing the infrared receiver 720. During infrared testing, the controller sends an infrared function activation command to the mobile phone via wireless communication, and the mobile phone's infrared transmitter emits an infrared signal. The infrared receiver 720 receives the infrared signal and transmits the received signal to the controller. The controller determines whether the mobile phone's infrared function is working properly based on whether the infrared receiver 720 receives the signal and the signal strength.

[0058] After the mobile phone completes the screen test and infrared test at the fifth test station 700, the first lifting and blocking mechanism 180 puts the mobile phone back onto the first conveyor belt 100, and the first conveyor belt 100 transports the mobile phone to the sixth test station 730.

[0059] like Figure 12 As shown, a second NFC testing module is installed on the sixth testing station 730. The second NFC testing module includes an NFC mounting base 731, an NFC blocking cylinder 732, an NFC blocking block 733, a card reader mounting base 734, and an NFC card reader 735. The NFC mounting base 731 is fixedly installed on the first machine tool 1000. The NFC blocking cylinder 732 is vertically installed on the NFC mounting base 731, and the NFC blocking block 733 is connected to the output end of the NFC blocking cylinder 732. When the piston rod of the NFC blocking cylinder 732 extends, the NFC blocking block 733 moves upward and extends above the first conveyor belt 100; when the piston rod of the NFC blocking cylinder 732 retracts, the NFC blocking block 733 moves downward and retracts below the first conveyor belt 100. The card reader mounting base 734 is mounted on the NFC mounting base 731 and located below the first conveyor belt 100. The NFC card reader 735 is mounted on the card reader mounting base 734 with the sensing side of the NFC card reader 735 facing upwards and directly towards the conveyor belt.

[0060] When the mobile phone is conveyed to the sixth test station 730, the NFC blocking cylinder 732 has already been activated, driving the NFC blocking block 733 to extend above the conveyor belt. The first conveyor belt 100 conveys the mobile phone forward along the conveying direction. After the mobile phone comes into contact with the NFC blocking block 733, it is blocked. At this time, the mobile phone is directly above the NFC reader 735. The NFC reader 735 communicates with the mobile phone via radio frequency signals to read the mobile phone's NFC information or write preset information to the mobile phone. The mobile phone sends the communication result to the controller via wireless communication. The controller determines whether the mobile phone's NFC function is normal based on the communication result.

[0061] like Figure 13As shown, the first defective product gripping mechanism 840 includes a gantry frame 801, a lateral drive module 802, a gripping rotary cylinder 803, a gripping lifting cylinder 804, and a gripping claw cylinder 805. The gantry frame 801 spans the first conveyor belt 100 and the first defective product conveyor belt 3000, providing support for the entire gripping mechanism. The lateral drive module 802 is mounted on the gantry frame 801 and can be a synchronous belt motor module, a lead screw motor module, or other existing linear drive devices, capable of driving the gripping mechanism to move laterally. The gripping rotary cylinder 803 is mounted on the output end of the lateral drive module 802 and can drive the gripping mechanism to rotate around a vertical axis. The gripping lifting cylinder 804 is mounted on the output end of the gripping rotary cylinder 803 and can drive the gripping mechanism to lift vertically. The material-grabbing claw cylinder 805 is installed on the output end of the material-grabbing lifting cylinder 804. Two clamping blocks 806 are provided on the output end of the material-grabbing claw cylinder 805. The material-grabbing claw cylinder 805 can drive the two clamping blocks 806 to close or separate from each other, so as to clamp and release the mobile phone.

[0062] Once the mobile phone completes testing at the sixth testing station 730, if all tests are passed, the phone is deemed a good product. The first conveyor belt 100 then transports the phone from the first machine 1000 to the second conveyor belt 200. If any test fails, the phone is deemed a defective product. At this time, the first defective product gripping mechanism 840 is activated, and the lateral drive module 802 drives the picking mechanism to move above the first conveyor belt 100 where the defective mobile phone is located. The picking lifting cylinder 804 extends, causing the picking claw cylinder 805 to descend to the height of the mobile phone. The picking claw cylinder 805 activates, causing the two clamping blocks 806 to close and clamp the mobile phone. The picking lifting cylinder 804 retracts and lifts the mobile phone. The picking rotary cylinder 803 rotates and adjusts its direction as needed. The lateral drive module 802 then drives the picking mechanism to move above the first defective product conveyor belt 3000. The picking lifting cylinder 804 extends, causing the mobile phone to descend onto the first defective product conveyor belt 3000. The picking claw cylinder 805 activates, causing the two clamping blocks 806 to separate and release the mobile phone. The picking lifting cylinder 804 retracts and returns to its original position. Defective mobile phones are placed on the first defective product conveyor belt 3000, which then sends them out of the first machine station 1000 for further sorting or repair.

[0063] The structure and working principle of the second defective product gripping mechanism 170 are the same as those of the first defective product gripping mechanism 840; therefore, the specific structure of the second defective product gripping mechanism 170 will not be described in detail here.

[0064] like Figure 14As shown, the first headphone testing module 810 includes headphone jack components respectively disposed on the first conveyor frame 210 and the second conveyor frame 220. The reason for providing headphone jack components on both the first and second conveyor frames 210 is to improve the versatility of the equipment; because the headphone jack positions differ between different mobile phone models—some have them located at the top, while others have them at the bottom. To accommodate both situations, headphone jack components are disposed on the two conveyor frames. One is located on the left side of the second conveyor belt 200 for inserting into phones with headphone jacks at the top, and the other is located on the right side of the second conveyor belt 200 for inserting into phones with headphone jacks at the bottom. Regardless of whether the headphone jack is at the top or bottom, after the phone is positioned by the second lifting and blocking mechanism 190, one headphone jack component will always be aligned with the headphone jack, thus achieving precise insertion testing.

[0065] Specifically, the headphone jack assembly includes a headphone test holder 811, which is fixedly connected to either the first conveyor frame 210 or the second conveyor frame 220. The headphone test holder 811 is equipped with a headphone test cylinder 812, and the output end of the headphone test cylinder 812 is equipped with a headphone plug 813, which is electrically connected to a controller. The headphone test cylinder 812 can drive the headphone plug 813 to connect or disconnect from the mobile phone on the lifting and blocking mechanism.

[0066] After the phone is lifted and positioned by the second lifting and blocking mechanism 190, the headphone test cylinder 812 drives the headphone plug 813 to move towards the phone, inserting it into the phone's headphone jack. Once inserted, the controller controls the phone to play a preset audio signal. The controller receives and analyzes the audio signal output by the phone through the headphone plug 813 to determine if the phone's headphone function is working properly. After the test is complete, the headphone test cylinder 812 drives the headphone plug 813 to be pulled out of the phone's headphone jack, achieving separation.

[0067] like Figure 14 As shown, the flash test module 830 includes a prism assembly and a shooting assembly. The prism assembly includes a prism mounting base 831 and at least two reflecting prisms 832, which are mounted on the prism mounting base 831. At least one reflecting prism 832 is located directly below the mobile phone on the second lifting blocking mechanism 190. During testing, the flash of the mobile phone on the phone holder 185 is located directly above this reflecting prism 832. The light emitted by the flash can shine downwards onto the reflecting prism 832, which can reflect the light onto the other reflecting prism 832. Additionally, at least one reflecting prism 832 is also located directly below the shooting assembly to reflect light onto the shooting assembly.

[0068] It should be noted that the mobile phone flash on the second conveyor belt 200 is usually facing downwards, i.e., opposite to the direction of the mobile phone screen; while on the second conveyor belt 200, the mobile phone is usually placed screen-up. Therefore, it is necessary to set up a prism assembly, using a reflecting prism 832 to change the light path, guiding the light emitted by the downward-facing flash after multiple reflections to directly below the shooting component, so that the shooting component can be installed above the lifting and blocking mechanism, thereby enabling testing of the downward-facing flash on the mobile phone on the lifting and blocking mechanism. This light path deflection design cleverly solves the problem of difficulty in direct shooting when the flash is facing downwards, making the equipment structure more compact and reasonable.

[0069] In this embodiment, the optical path of the flash test module 830 is: flash emitting light downwards → first reflecting prism → second reflecting prism → imaging component. In other embodiments, one or more intermediate reflecting prisms may be added between the first and second reflecting prisms. The only requirement is to ensure that the light emitted by the flash can ultimately be captured by the imaging component.

[0070] The shooting assembly includes a shooting mount 833, on which a shooting camera 834 is mounted. The shooting camera 834 is adjustablely and limitably connected to the shooting mount 833. The shooting camera 834 is used to photograph the reflecting prism 832. By adjusting the mounting height of the shooting camera 834, the shooting focal length can be adjusted to meet the testing requirements of different mobile phones. The shooting camera 834 is located directly above the last reflecting prism 832 in the optical path of the prism assembly. The shooting camera 834 captures the image of the flash reflected from the reflecting prism 832 and transmits the image to the controller for analysis to determine whether the flash brightness, uniformity, etc., meet the standards.

[0071] like Figure 15 As shown, the side fingerprint testing module 910 includes a side fingerprint testing frame 911, which is fixedly mounted on the second machine base 2000. A side fingerprint testing cylinder 912 is mounted on the side fingerprint testing frame 911, and the side fingerprint testing cylinder 912 is tunably connected to the side fingerprint testing frame 911. By adjusting the mounting position of the side fingerprint testing cylinder 912 on the side fingerprint testing frame 911, the horizontal position of the side fingerprint testing cylinder 912 can be changed, thus adapting to the testing needs of mobile phones with side fingerprints in different positions. A side fingerprint testing head 913 is mounted on the output end of the side fingerprint testing cylinder 912, which can drive the side fingerprint testing head 913 to contact or separate from the mobile phone on the second lifting and blocking mechanism 190.

[0072] After the phone is lifted and positioned by the second lifting and blocking mechanism 190, the side fingerprint test cylinder 912 drives the side fingerprint test head 913 to move towards the phone, so that the side fingerprint test head 913 comes into contact with the fingerprint recognition area on the side of the phone. The side fingerprint test head 913 simulates a finger pressing the fingerprint recognition area, and the controller reads the fingerprint recognition result of the phone to determine whether the side fingerprint recognition function is normal. After the test is completed, the side fingerprint test cylinder 912 drives the side fingerprint test head 913 to separate from the phone.

[0073] like Figure 15 As shown, the second light-sensing test module 920 includes a light source mounting bracket 921, which is fixedly mounted on the side fingerprint test bracket 911. A light-sensing light source 922 is mounted on the light source mounting bracket 921, positioned directly above the mobile phone on the second lifting blocking mechanism 190. The light-sensing light source 922 is adjustablely connected to the light source mounting bracket 921. By adjusting the mounting height of the light-sensing light source 922 on the light source mounting bracket 921, the distance between the light-sensing light source 922 and the mobile phone can be changed, thus adapting it to the testing needs of different mobile phones.

[0074] The testing principle of the light sensor is as follows: Light is provided above the light sensor of the phone, and the phone's ability to automatically adjust screen brightness according to the light intensity is tested. The light source 922 emits light of a preset intensity onto the phone's light sensor. The controller reads the light sensor's detection value and determines whether it matches the preset light intensity, thus determining whether the light sensor is working properly.

[0075] like Figure 16 As shown, in this embodiment, two speaker testing modules are provided on the eleventh test station 150, and the two speaker testing modules are respectively installed on the first conveyor frame 210 and the second conveyor frame 220. The purpose of this design is to improve the testing accuracy and adapt to the speaker layout of different mobile phones. Specifically, the position of the mobile phone speaker varies depending on the model: some mobile phone speakers are located at the top of the phone, that is, the earpiece position also serves as the external speaker; some are located at the bottom of the phone, that is, on the side of the charging port; and some models have speakers at both the top and bottom to achieve a stereo effect. In order to be compatible with all the above situations and ensure the accuracy of the test data, this embodiment adopts a dual-microphone layout 152.

[0076] Specifically, the speaker testing module includes a speaker testing mounting bracket 151, which is connected to a corresponding first conveyor frame 210 or second conveyor frame 220. A microphone 152 is mounted on the speaker testing mounting bracket 151 and is electrically connected to a controller. The two microphones 152 are spatially located above and below the second conveyor belt 200, respectively. When the mobile phone is lifted and positioned by the second lifting and blocking mechanism 190 corresponding to the fifth testing station 700, the speaker at the top of the mobile phone faces the microphone 152 located above it, and the speaker at the bottom of the mobile phone faces the microphone 152 located below it.

[0077] During speaker testing, the controller directs the phone to play preset test sound sources sequentially or simultaneously. The upper microphone 152 primarily captures sound emitted from the top of the phone, while the lower microphone 152 primarily captures sound emitted from the bottom of the phone. The controller receives the audio signals from both microphones 152 and compares them with a built-in standard signal to determine the speaker's distortion and true loudness under the current environment, thereby judging whether the speaker's performance meets the standards.

[0078] For phones with speakers at both the top and bottom, this dual-module layout allows the device to simultaneously test the synergistic effect of the two speakers (stereo testing) or test their independent performance separately. For phones with speakers on only one side, the corresponding microphone can collect sound at the closest distance, reducing interference from environmental noise and sound propagation attenuation, thereby significantly improving the testing accuracy of distortion and loudness.

[0079] The defective product gripping station 160 is equipped with a defective product blocking component. This component is used to stop the mobile phone on the second conveyor belt 200 at the defective product gripping station 160. After the mobile phone completes all tests on the second machine 2000, if it is determined to be defective, the second conveyor belt 200 transports it to the defective product gripping station 160, where the defective product blocking component blocks the phone, awaiting the second defective product gripping mechanism 170 to grip and remove it.

[0080] like Figure 17 As shown, the defective product blocking assembly includes a defective product blocking mounting base 161, which is fixedly mounted on the second machine tool 2000. The defective product blocking mounting base 161 is equipped with a defective product blocking cylinder 162, and a defective product blocking block 163 is provided on the output end of the defective product blocking cylinder 162. The defective product blocking cylinder 162 can drive the defective product blocking block 163 to move up and down, thereby causing the defective product blocking block 163 to extend above the second conveyor belt 200 or retract below the second conveyor belt 200.

[0081] When a mobile phone is determined to be defective after completing all tests, the second conveyor belt 200 transports the phone to the defective product gripping station 160. The defective product blocking cylinder 162 drives the defective product blocking block 163 to extend upwards above the second conveyor belt 200, blocking the defective phone at the defective product gripping station 160. After the second defective product gripping mechanism 170 removes the phone, the defective product blocking cylinder 162 drives the defective product blocking block 163 to retract downwards below the second conveyor belt 200, releasing the obstruction.

[0082] Working principle: The host computer or a person places the mobile phone into the first end of the first conveyor belt 100. The first conveyor belt 100 then moves the phone to the scanning position of the first scanning mechanism 110, where the first scanning mechanism 110 scans the identification code to establish wireless communication with the controller, completing identity binding and data tracking. Subsequently, the first conveyor belt 100 sequentially transports the phone to the first through sixth test stations 730, where it sequentially performs tests on multiple functions, including proximity sensor, charging function, microphone pickup, light sensor, gyroscope, NFC, side button, in-screen fingerprint, vibration motor, screen display, and infrared emission. After completing all predetermined items on the first test station 1000, the phone transitions directly from the end of the first conveyor belt 100 to the beginning of the second conveyor belt 200, where the second scanning mechanism 120 scans it again to confirm its identity, maintain communication, and enter the testing process on the second test station 2000. If any test item fails, the phone is deemed defective. Mobile phones that are judged to be defective on the first machine station 1000 will be picked up from the sixth test station 730 by the first defective product grabbing mechanism 840 and placed on the first defective product conveyor belt 3000 to be sent out of the first machine station 1000.

[0083] On the second machine 2000, the mobile phone passes through the seventh to eleventh testing stations 150 sequentially along the second conveyor belt 200, continuing to complete supplementary tests such as headphone jack retest, charging function retest, flash, proximity sensor retest, side fingerprint retest, light sensor retest, headphone jack retest, screen fingerprint retest, and speaker audio playback. If any test item fails, the mobile phone is judged as a defective product. Mobile phones judged as defective on the second machine 2000 are then conveyed to the defective product grabbing station 160, where the second defective product grabbing mechanism 170 grabs them and sends them out onto the second defective product conveyor belt 4000. Only mobile phones that pass all tests are considered good products and are normally sent out of the second machine 2000 by the second conveyor belt 200 to enter the next production stage.

[0084] This mobile phone functional testing production line incorporates several ingenious structural design features to ensure high efficiency and accuracy in testing. Firstly, two parallel first conveyor belts 100 and two parallel second conveyor belts 200 enable dual-channel parallel testing, allowing two mobile phones to undergo different stages of testing simultaneously on two different machines, significantly improving overall efficiency. Secondly, each conveyor belt is equipped with a conveyor adjustment mechanism 250, which can adjust the spacing of the two conveyor belts 230 to accommodate mobile phones of different lengths, enhancing the equipment's versatility. Furthermore, each testing station is equipped with a lifting and blocking mechanism. Through blocking blocks 184, lifting of the mobile phone tray 185, and clamping from the side by positioning cylinders 186, the mobile phone is precisely fixed in the preset testing position, ensuring reliable test results. Through the close coordination of each component, fully automated, high-efficiency, and high-precision continuous testing of multiple mobile phone functions is achieved, meeting the needs of mass production.

All equivalent changes made in accordance with the present invention are within the protection scope of the present invention.
