[0032] The code scanning docking station 100 is used to calibrate the opening and closing position of the laptop computer, so that each laptop computer can be opened at a fixed angle before testing, thereby improving the consistency of the test; in this embodiment, during the test, each laptop computer can be opened 90° after the code scanning docking station 100 is used. In other embodiments, any other opening angle can also be selected for testing. The code scanning docking station 100 can also scan the code of the laptop computer so that the laptop computer is connected to the control center so that the control center can control the laptop computer for testing. At the same time, the code scanning docking station 100 can also send the scanned laptop computer to the second conveyor line 21. Usually, the test program is installed in advance on the laptop computer, and it is connected to the control center after scanning the code so that the control center can control the laptop computer to run the corresponding test program, thereby realizing the test process. In this embodiment, after the code scanning docking station 100 scans the laptop computer, the laptop computer can communicate with the control center via wifi.

[0033] The speaker test device 200 is used to test the speaker performance and keyboard resonance performance of the laptop computer, and can deliver the tested laptop computer to the third conveyor line 500; the fan noise test device 300 is used to test the noise of the cooling fan of the laptop computer, and deliver the tested laptop computer to the fifth conveyor line 600.

The microphone test device 400 is used to test the microphone performance and air tightness of the laptop computer, and can deliver the tested laptop computer to the material receiving assembly 700.

[0034] During operation, the host computer or a human being places the laptop computer to be tested on the first conveyor line 11, controls the code scanning docking station 100 to operate, can calibrate the position and opening and closing angle of the laptop computer, and scans and identifies the identification code on the laptop computer, so that the laptop computer on the first conveyor line 11 is connected to the control center of the assembly line; then the laptop computer is conveyed to the second conveyor line 21 through the first conveyor line 11, and then the speaker performance and keyboard resonance performance of the laptop computer are tested by controlling the speaker testing equipment 200 to operate; then the laptop computer is conveyed to the third conveyor line 500 through the second conveyor line 21, and the laptop computer is conveyed to the third conveyor line 500 by controlling the third conveyor line 500 to be connected to the control center of the assembly line; The computer is conveyed to the fourth conveyor line 31; the fan noise test device 300 is controlled to work to detect the fan noise of the laptop computer when it is working; after the test, the laptop computer is conveyed to the fifth conveyor line 600 through the fourth conveyor line 31, and the laptop computer is conveyed to the sixth conveyor line 41 through the fifth conveyor line 600; then the microphone test device 400 is controlled to work to test the microphone performance and the air tightness of the laptop computer; after the test, the laptop computer is conveyed to the receiving assembly 700 through the sixth conveyor line 41 to complete the entire test process; the operator or the robot arm then takes out the tested laptop computer from the receiving assembly 700 to complete the unloading.

[0035] The laptop computer automated testing line adopts an assembly line-style operation process, connecting multiple devices to work online and cooperate with each other. There is no need for manual transfer of laptop computers. It can simultaneously complete the testing of the speaker performance, keyboard resonance performance, cooling fan noise, microphone performance and microphone air tightness on the laptop computer. The use of machines instead of manual labor reduces the labor cost of testing and can also greatly improve testing efficiency.

[0036] In order to improve the accuracy of the test structure, in this embodiment, the speaker test device 200, the fan noise test device 300 and the microphone test device 400 are all provided with a protective cover 80. The protective cover 80 can reduce the entry of external noise, so that the test environment is in a relatively quiet scene, so as to test the microphone, speaker and cooling fan of the laptop computer and improve the accuracy of the test.

[0037] like Figure 3 , Figure 5 , Figure 6 As shown, for the convenience of operation, a material passing notch 81 is provided on the left and right sides of the protective cover 80, and the material passing notch 81 is respectively arranged at the corresponding position of the corresponding conveying line, for example, the material passing notch 81 on the speaker testing device 200 is arranged at the corresponding position of the second conveying line 21. The material passing notch 81 is used for the laptop computer to be tested to pass through, so that the laptop computer can flow between various devices. An opening and closing mechanism 82 is provided at the corresponding position of the protective cover 80 with the material passing notch 81, and the opening and closing mechanism 82 is used to open or close the material passing notch 81.

[0038] Specifically, the opening and closing mechanism 82 includes an opening and closing mounting plate 821, which is fixedly connected to the protective cover 80. An opening and closing cylinder 822 is provided on the opening and closing mounting plate 821, and an opening and closing block 823 is provided on the output end of the opening and closing cylinder 822. The opening and closing cylinder 822 can drive the opening and closing block 823 to move so that the opening and closing block 823 opens or closes the material passing gap 81.

[0039] In this embodiment, the material notch 81 is in a right angle shape, and the opening block is adapted to the shape of the material notch 81; the opening and closing cylinder 822 is tilted at a 45° angle on the protective cover 80. The opening and closing cylinder 822 is tilted at a 45° angle to shorten the cylinder stroke to the maximum extent, thereby improving the processing efficiency; it can also reduce the size of the opening and closing cylinder 822 and save the manufacturing cost.

[0040] like Figure 4As shown, the barcode scanning docking station 100 includes a first machine base 12, a first conveyor line 11 is installed on the first machine base 12, a positioning frame 13 and a push cylinder 14 are also provided on the first machine base 12, one end of the positioning frame 13 extends into the first conveyor line 11, and a push block 15 is provided on the output end of the push cylinder 14, and the push block 15 is used to push the laptop computer to slide horizontally on the first conveyor line 11; during processing, the host computer or the manipulator places the laptop computer on the first conveyor line 11, drives the laptop computer to move to the corresponding position of the positioning frame 13 through the first conveyor line 11, and then controls the push cylinder 14 to work and push the laptop computer to slide horizontally on the first conveyor line 11 until the laptop computer is away from the side of the push block 15 and abuts against the positioning frame 13. Through the cooperation of the push cylinder 14 and the positioning frame 13, each laptop computer is in a uniform position during testing, which improves the accuracy and stability of the test.

[0041] A flip cylinder 16 is installed on the positioning frame 13, and a suction cup mounting plate 17 is provided on the output end of the flip cylinder 16. A plurality of negative pressure suction cups 18 are installed on the suction cup mounting plate 17. The negative pressure suction cups 18 are externally connected to a negative pressure device to generate negative pressure suction, which is used to abut against the back of the laptop computer. The flip cylinder 16 is used to drive the laptop computer screen to flip and open. During processing, when the push cylinder 14 is completed, the two sides of the laptop computer abut against the push block 15 and the positioning frame 13 respectively; then the flip cylinder 16 is controlled to work, and the negative pressure suction cup 18 is driven to move in the direction close to the laptop computer until the negative pressure suction cup 18 abuts against the back of the laptop computer screen, and the negative pressure suction cup 18 will absorb the back of the laptop computer screen; then the flip cylinder 16 is controlled to reset, and the negative pressure suction cup 18 is driven to move in the direction away from the laptop computer, and the negative pressure suction cup 18 will pull the laptop computer screen corresponding to the keyboard to rotate until the flip cylinder 16 is reset; then the negative pressure device external to the negative pressure suction cup 18 is controlled to stop negative pressure suction. The laptop computer can be flipped and opened to a fixed angle by the flipping cylinder 16 and the negative pressure suction cup 18, so that each laptop computer can be opened at a fixed angle before testing, thereby improving the accuracy and stability of the test.

[0042] A scanning terminal 19 is provided on one side of the first base 12 near the push cylinder 14. The scanning terminal 19 is used to identify the identification code on the laptop computer on the first conveyor line 11. Before the laptop computer is tested, a QR code will be displayed on its screen; in the specific processing process, when the negative pressure suction cup 18 opens the laptop computer to a suitable angle, the QR code on the screen can be scanned by the scanning terminal 19, so that the laptop computer can establish a connection with the control center of the test assembly line, so that the control center can control the laptop computer for testing. After the scanning terminal 19 finishes scanning, the push cylinder 14 is controlled to reset, and the push block 15 is driven to move away from the laptop computer, so that the push block 15 is separated from the laptop computer; then the first conveyor line 11 is controlled to work, and the laptop computer is sent to the second conveyor line 21 through the material notch 81.

[0043] like Figure 6 As shown, the speaker testing device 200 includes a second base 22, and the second conveyor line 21 is fixedly mounted on the second base 22. The second conveyor line 21 is provided with a first blocking component 23 and a first clamping and positioning component 24. The first blocking component 23 is used to limit the position of the laptop computer on the second conveyor line 21, so that each laptop computer can stay at a uniform position on the second conveyor line 21, thereby improving the consistency of the test; the first clamping and positioning component 24 is used to resist the two sides of the laptop computer, so that the laptop computer is fixed at the upper limit on the second conveyor line 21, so as to test the resonance of the speaker and keyboard of the laptop computer, thereby improving the stability and accuracy of the test. The second base 22 is provided with a pickup component 25, which is used to pick up the sound played by the speaker when the laptop computer is working or the vibration sound of the keyboard when the laptop computer is working; during the test, the control center will control the laptop computer on the second conveyor line 21 to play the audio file, and the corresponding sound can be picked up by the pickup component 25, thereby judging whether the speaker performance of the laptop computer and the resonance sound of the keyboard are qualified.

[0044] In order to improve the accuracy of the test, a background noise pickup microphone 26 is also provided on the second base 22, and the background noise pickup microphone 26 is arranged on the side of the second base 22 away from the second conveyor line 21; the background noise pickup microphone 26 is used to pick up the background noise in the protective cover 80 of the speaker testing equipment 200, and feed back the background noise information to the control center; the control center uses a software algorithm to eliminate the background noise from the sound picked up by the sound pickup component 25, and the sound is the sound of the speaker playback or the resonance sound of the keyboard. By obtaining the background noise and offsetting it, the accuracy of the test can be improved.

[0045] Specifically, Figure 7As shown, the second conveyor line 21 includes two parallel conveyor racks 211, the conveyor racks 211 are connected to the second base 22, each conveyor rack 211 is provided with a conveyor belt 212, and the second base 22 is provided with a conveyor drive assembly 213 for driving the conveyor belt 212 to move, and the conveyor drive assembly 213 is a motor pulley structure, which drives the conveyor belt 212 to move on the conveyor rack 211 through the rotation of the motor drive pulley, so as to achieve the purpose of driving the notebook computer to move. The second base 22 is also provided with a conveyor adjustment mechanism 214 for adjusting the distance between the two conveyor racks 211, and the conveyor adjustment mechanism 214 is a motor screw structure, which drives the screw to rotate by controlling the motor work, and then drives one of the conveyor racks 211 to move in the direction of approaching or moving away from the other conveyor rack 211, so that the distance between the two conveyor racks 211 changes, so that the distance between the two conveyor belts 212 changes synchronously, so that it can be suitable for the testing needs of notebook computers of different sizes.

[0046] In order to meet the testing requirements of laptop computers of different sizes, a blocking adjustment mechanism 27 for adjusting the position of the first blocking component 23 is installed on the conveyor frame 211. The blocking adjustment mechanism 27 is a motor screw structure. The first blocking component 23 is installed on the output end of the blocking adjustment mechanism 27. By controlling the operation of the motor, the first blocking component 23 can be driven to move on the conveyor frame 211 in a direction parallel to the movement direction of the conveyor belt 212, so that the first blocking component 23 can block laptop computers of different sizes on the conveyor belt 212 at a position corresponding to the pickup component 25, so that the pickup component 25 can test the speaker performance and keyboard resonance of the laptop computer.

[0047] The first blocking assembly 23 includes a blocking cylinder 231, which is installed on the output end of the blocking adjustment mechanism 27. A blocking block 232 is provided on the output end of the blocking cylinder 231. The blocking cylinder 231 can drive the blocking block 232 to move in a direction perpendicular to the moving direction of the conveyor belt 212, and make the blocking block 232 extend into or extend out of the conveyor belt 212. Normally, the blocking cylinder 231 extends so that the blocking block 232 extends into the conveyor belt 212; when working, the conveyor belt 212 drives the laptop to move. When the laptop moves to the corresponding position of the blocking block 232, the blocking block 232 will abut against one end of the laptop, so that the conveyor belt 212 can no longer drive the laptop to move. At this time, the laptop just moves to the position relative to the pickup assembly 25. After the test of the pickup assembly 25 is completed, the blocking cylinder 231 is controlled to retract, and the blocking block 232 is driven to separate from the laptop. After that, the conveyor belt 212 can drive the laptop to move and transport it to the third conveyor line 500.

[0048] The first clamping and positioning assembly 24 includes clamping cylinders 241 symmetrically distributed on the two conveying racks 211 , one clamping cylinder 241 is installed on each conveying rack 211 , and the two clamping cylinders 241 are arranged opposite to each other, and clamping blocks 242 are respectively provided on the output ends of the clamping cylinders 241 . During the test, after the blocking block 232 blocks the laptop computer, the conveyor belt 212 is controlled to stop working; then the two clamping cylinders 241 are controlled to work, driving the clamping blocks 242 to move towards the conveyor belt 212, until the two clamping blocks 242 are respectively in contact with the two sides of the laptop computer, and the laptop computer is clamped by the two clamping blocks 242 so that it can no longer move; then the speaker of the laptop computer is controlled to play audio, and then the speaker performance and keyboard resonance performance of the laptop computer are tested through the cooperation of the pickup component 25 and the background noise pickup microphone 26; after the test is completed, the clamping cylinder 241 is controlled to reset, and at the same time the blocking cylinder 231 is controlled to retract, so that the blocking block 232 and the two clamping blocks 242 are respectively separated from the laptop computer; then the laptop computer is transported to the third conveyor line 500 through the conveyor belt 212.

[0049] like Figure 8 As shown, the sound pickup assembly 25 includes a first sound pickup mechanism 251, a second sound pickup mechanism 252 and a third sound pickup mechanism 253. The first sound pickup mechanism 251 and the second sound pickup mechanism 252 are respectively arranged above the second conveying line 21, and the third sound pickup mechanism 253 is arranged below the second conveying line 21. According to different types of notebook computer speakers, the first sound pickup mechanism 251, the second sound pickup mechanism 252 or the third sound pickup mechanism 253 can be freely called, or the first sound pickup mechanism 251, the second sound pickup mechanism 252 or the third sound pickup mechanism 253 can be called simultaneously or partially, and the present invention is not limited to this.

[0050] The first sound pickup mechanism 251 , the second sound pickup mechanism 252 and the third sound pickup mechanism 253 have the same structure, and the third sound pickup mechanism 253 is used for explanation herein.

[0051] Specifically, Fig. 9 As shown, the third sound pickup mechanism 253 includes a longitudinal driving module 2531, which is connected to the second base 22, and a transverse driving module 2532 is provided on the output end of the longitudinal driving module 2531, and a microphone mounting block 2533 is provided on the output end of the transverse driving module 2532, and a sound pickup microphone 2534 is provided on the microphone mounting block 2533. In specific operation, since the speaker positions of various models of laptop computers are not the same, the longitudinal driving module 2531 can be used to drive the transverse driving module 2532 and the sound pickup microphone 2534 to move longitudinally, and the transverse driving module 2532 can be used to drive the sound pickup microphone 2534 to move transversely, so that the position of the sound pickup microphone 2534 can be freely moved on a two-dimensional plane, so that it can be suitable for different types of laptop computer testing requirements.

[0052] Both the transverse drive module 2532 and the longitudinal drive module 2531 are motor screw structures, and their specific structures are not described in detail herein.

[0053] In this embodiment, two sound pickup microphones 2534 are provided on the lateral drive module 2532. The screw rod on the lateral drive module 2532 is a bidirectional screw rod, and the two sound pickup microphones 2534 can be driven to move closer to each other or away from each other through the lateral drive module 2532. Because many laptop computers have two symmetrically arranged speakers, by providing two sound pickup microphones 2534, the sound of the two speakers can be picked up at the same time, thereby improving the accuracy and convenience of the test.

[0054] The third conveyor line 500 is fixedly connected to the speaker test equipment 200 and the fan noise test equipment 300, respectively. The fifth conveyor line 600 is fixedly connected to the fan noise test equipment 300 and the microphone test equipment 400, respectively. The third conveyor line 500 and the fifth conveyor line 600 are both structures in which the motor pulley drives the belt to rotate, and their structures are not described in detail in this article. In other embodiments, any existing structure or device that can drive the linear movement of the laptop computer can also be used.

[0055] The structure of the fan noise test device 300 is the same as that of the speaker test device 200, and the specific structure of the fan noise test device 300 is not described in detail herein. When performing the fan noise test, the control center of the assembly line will control the laptop to work normally, and through the cooperation of the pickup microphone 2534 and the background noise pickup microphone 26, and through the software algorithm of the control center, the fan noise of the laptop can be obtained when the laptop is working, so as to judge whether the fan noise of the laptop is within the qualified range, thereby realizing the test process of the fan noise of the laptop.

[0056] like Fig.10 As shown, the microphone testing device 400 includes a third base 42, and a sixth conveyor line 41 is fixedly mounted on the third base 42. The sixth conveyor line 41 has the same structure as the second conveyor line 21, so the structure of the sixth conveyor line 41 is not described in detail herein. A second blocking assembly 43 and a second clamping and positioning group 44 are installed on the sixth conveyor line 41. The second blocking assembly 43 is used to limit the position of the laptop computer on the sixth conveyor line 41, so that each laptop computer can stay at a uniform position on the sixth conveyor line 41, thereby improving the consistency of the test; the second blocking assembly 43 has the same structure as the first blocking assembly 23, and the structure of the second blocking assembly 43 is described in detail herein. The second clamping and positioning group 44 is used to hold against both sides of the laptop computer, so as to test the microphone performance and air tightness of the laptop computer, thereby improving the stability and accuracy of the test.

[0057] The structure of the second clamping and positioning group 44 is similar to that of the first clamping and positioning component 24, the difference being that the second clamping component has three clamping cylinders 241, and the three clamping cylinders 241 are distributed in a triangle on both sides of the sixth conveyor line 41; when working, the three clamping cylinders 241 work simultaneously, driving the corresponding clamping blocks 242 to move, and the three clamping blocks 242 are used to press against both sides of the laptop computer, thereby limiting and fixing the laptop computer on the sixth conveyor line 41.

[0058] The third base 42 is provided with a first broadcasting speaker 45 and a second broadcasting speaker 46. The first broadcasting speaker 45 is arranged directly above the sixth conveying line 41, and the second broadcasting speaker 46 is arranged obliquely above the side of the sixth conveying line 41. According to the different installation positions of the microphone of the tested laptop computer, the first broadcasting speaker 45 and / or the second broadcasting speaker 46 can be controlled to play audio respectively, so that the laptop computer on the sixth conveying line 41 picks up the corresponding sound, so as to test whether the microphone performance of the laptop computer is normal.

[0059] The third base 42 is also provided with a first hole blocking mechanism 47 and a second hole blocking mechanism 48. The first hole blocking mechanism 47 is arranged above the sixth conveying line 41, and the second hole blocking mechanism 48 is arranged at one side of the sixth conveying line 41. The first hole blocking mechanism 47 and the second hole blocking mechanism 48 are respectively used to block the sound outlet holes of the laptop computers on the sixth conveying line 41. According to the different installation positions of the microphones on different laptop computers, the first hole blocking mechanism 47 or the second hole blocking mechanism 48 can be controlled to work, and the sound outlet holes of the laptop computers are blocked by the first hole blocking mechanism 47 or the second hole blocking mechanism 48, so as to test the air tightness of the microphones of the laptop computers on the sixth conveying line 41.

[0060] During the specific test, after the sixth conveyor line 41 conveys the laptop computer to the corresponding position of the second blocking component 43, it is blocked on the sixth conveyor line 41 by the second blocking component 43; and then the laptop computer is clamped and fixed by the second clamping and positioning group 44. Then the first broadcasting speaker 45 and / or the second broadcasting speaker 46 are controlled to play the test audio, and the microphone of the laptop computer on the sixth conveyor line 41 will pick up the audio information, and feed back the picked up audio information to the control center, and the control center can judge whether the microphone performance of the laptop computer is normal. Then the first hole blocking mechanism 47 or the second hole blocking mechanism 48 is controlled to work, and the sound outlet of the laptop computer on the sixth conveyor line 41 is sealed by the first hole blocking mechanism 47 or the second hole blocking mechanism 48, and then the test audio is played by the first broadcasting speaker 45 and / or the second broadcasting speaker 46, and the microphone of the laptop computer on the sixth conveyor line 41 will pick up the audio information, and feed back the picked up audio information to the control center. The control center can judge whether the air tightness of the microphone of the laptop computer is qualified by comparing the two data when the sound outlet hole is sealed and the sound outlet hole is not sealed.

[0061] It should be noted that the microphones of laptops are mainly distributed in the following ways:

[0062] 1. The microphone is installed on the side periphery of the laptop display screen, usually on the side of the laptop camera.

[0063] 2. The microphone is installed below the built-in mouse of the laptop, usually on the inside of the bottom shell of the laptop.

[0064] Typically, the first hole blocking mechanism 47 is used to test the air tightness of the microphone of the first type of laptop computer; the second hole blocking mechanism 48 is used to test the air tightness of the microphone of the second type of laptop computer.

[0065] like Fig.11 As shown, the first hole blocking mechanism 47 includes a hole blocking lifting module 471, which is fixedly mounted on the third machine base 42, and is a motor screw structure. A clamping cylinder 472 is mounted on the output end of the hole blocking lifting module 471, and two silicone chucks 473 are arranged on the output end of the clamping cylinder 472. When testing the air tightness of the microphone of the first laptop computer mentioned above, the hole blocking lifting module 471 is controlled to work, and the clamping cylinder 472 is driven to descend until the two silicone chucks 473 move to both sides of the microphone of the laptop computer; then the clamping cylinder 472 is controlled to work, and the two silicone chucks 473 are driven to move closer to each other until the two silicone chucks 473 clamp the laptop computer and block the sound outlet of the laptop computer, and then the first broadcasting speaker 45 and / or the second broadcasting speaker 46 are controlled to play the test audio, so as to test the air tightness of the microphone of the laptop computer. After the test is completed, the clamping claw cylinder 472 is first controlled to work, driving the two silicone chucks 473 to separate; then the hole plugging lifting module 471 is controlled to reset, driving the silicone chuck 473 to rise and reset to the initial position.

[0066] like Fig.12As shown, in order to meet the processing requirements of laptop computers of different sizes, a hole blocking adjustment module 49 for driving the second hole blocking mechanism 48 to move horizontally is provided on the third base 42. The hole blocking adjustment module 49 can drive the second hole blocking mechanism 48 to move horizontally on the third base 42, and the driving direction of the hole blocking adjustment module 49 is perpendicular to the movement direction of the sixth conveyor belt 212; the motor screw structure of the hole blocking adjustment module 49 is not described in detail in this article. The second hole blocking mechanism 48 includes a hole blocking mounting block 481, and two hole blocking cylinders 482 are provided on the hole blocking mounting block 481, one of which is horizontally arranged and the other is tilted; because the outer shell of the laptop computer has different shapes, if the outer shell of the laptop computer is a right-angle structure, the horizontally arranged hole blocking cylinder 482 can be controlled to work; if the outer shell of the laptop computer is an oblique structure, the tilted hole blocking cylinder 482 can be controlled to work. The output ends of the two hole-blocking cylinders 482 are respectively installed with silicone plugs 483, and the hole-blocking cylinders 482 can drive the corresponding silicone plugs 483 to abut or separate from the laptop computer on the sixth conveyor line 41. Before testing the air tightness of the microphone of the second laptop computer, the hole-blocking adjustment module 49 is first controlled to drive the second hole-blocking mechanism 48 to move horizontally on the third base 42 until the second hole-blocking mechanism 48 can connect with the laptop computer on the sixth conveyor line 41; during the test, the corresponding hole-blocking cylinder 482 is controlled to work and drive the silicone plug 483 to move, so that the silicone plug 483 abuts against the sound outlet of the laptop computer on the sixth conveyor line 41, sealing the sound outlet of the laptop computer, and then controlling the first broadcasting speaker 45 and / or the second broadcasting speaker 46 to play the test audio, so as to test the air tightness of the laptop computer's microphone. After the test is completed, the hole-blocking cylinder 482 is controlled to reset, and the silicone plug 483 is driven to leave the laptop computer and reset to the initial position.

[0067] like Figure 2As shown, the receiving assembly 700 includes a receiving rack 71, which is fixedly connected to the third machine base 42, one end of which is connected to the discharging end of the sixth conveyor line 41, and a plurality of rotatable rollers 72 are installed on the receiving rack 71, and baffles 73 are installed on the sides of the receiving rack 71; by setting the rollers 72, the sixth conveyor line 41 will send the tested laptop computer out of the third machine base 42 and then flow into the rollers 72, and the rotating rollers 72 can reduce the friction of the laptop computer, thereby protecting the appearance of the product. By setting the baffles 73, the laptop computer can be prevented from falling out of the receiving rack 71, thereby improving the safety of the test. After the test is completed, the sixth conveyor line 41 will send the tested product out of the third machine base 42, and then flow into the rollers 72, and then the operator or the robot arm will take the laptop computer on the rollers 72 to complete the unloading. In other embodiments, the material receiving assembly 700 may also be replaced by a conveyor belt, and the tested products may be directly fed into the conveyor belt via the sixth conveyor line 41, and the products may be transported to the next workstation via the conveyor belt, thereby realizing an automated testing process without human intervention.

[0068] The laptop computer automated test line can test laptop computers of different sizes and types, greatly improving the versatility of the equipment. One line can meet the testing needs of most types of laptop computers on the market. Moreover, the laptop computer automated test line can simultaneously test the speaker performance, keyboard resonance, fan noise, microphone performance, and microphone air tightness of the laptop computer, covering almost all current test items for laptop computer audio performance. It is powerful, and the entire process is automated and controlled, without the need for human intervention. It has a high degree of automation, can save a lot of manpower, and improve test efficiency.
