[0036] In order to improve the accuracy of the test structure, in the embodiment, the horn test equipment 200, the fan noise test equipment 300 and the microphone test equipment 400 are all sleeved with protective covers 80. The protective cover 80 can reduce the external noise entering, so that the test environment is in a relatively quiet scene, so as to test the microphone, sound box and cooling fan of the notebook computer, and improve the accuracy of the test.

[0037] As shown in Figure 3 , Figure 5 , Figure 6 In order to facilitate operation, the protective cover 80 is provided with a material passing gap 81 on the left and right sides. The material passing gap 81 is arranged at the corresponding position of the conveying line, for example, the material passing gap 81 on the horn test equipment 200 is arranged at the corresponding position of the second conveying line 21. The material passing gap 81 is used for the notebook computer to pass through, so that the notebook computer can flow between the devices. The protective cover 80 is provided with an opening and closing mechanism 82 at the corresponding position of the material passing gap 81.

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 the embodiment, the material passing gap 81 is in a right angle shape, and the opening block is matched with the shape of the material passing gap 81. The opening and closing cylinder 822 is arranged on the protective cover 80 at an angle of 45°. Arranging the opening and closing cylinder 822 at an angle of 45° can shorten the cylinder stroke to the maximum, thereby improving the processing efficiency. Also, the size of the opening and closing cylinder 822 can be reduced, saving the manufacturing cost.

[0040] As shown in Figure 4As shown, the code scanning transfer station 100 includes a first base 12, a first conveying line 11 is installed on the first base 12, and a positioning frame 13 and a pushing cylinder 14 are further arranged on the first base 12. One end of the positioning frame 13 extends into the first conveying line 11, and a pushing block 15 is arranged on the output end of the pushing cylinder 14. The pushing block 15 is used to push the notebook computer to slide transversely on the first conveying line 11. During processing, the notebook computer is placed on the first conveying line 11 by the upper computer or the mechanical hand. The notebook computer is driven to move to the position corresponding to the positioning frame 13 by the first conveying line 11, and then the notebook computer is pushed to slide transversely on the first conveying line 11 by controlling the pushing cylinder 14 to work, until the side of the notebook computer away from the pushing block 15 abuts against the positioning frame 13. Through the cooperation of the pushing cylinder 14 and the positioning frame 13, the position of each notebook computer during testing is uniform, which improves the accuracy and stability of the test.

[0041] A turnover cylinder 16 is installed on the positioning frame 13, a suction disc mounting plate 17 is arranged on the output end of the turnover cylinder 16, a plurality of negative pressure suction discs 18 are installed on the suction disc mounting plate 17, and a negative pressure device is connected to the negative pressure suction disc 18 to generate negative pressure suction force, which is used to abut against the back of the notebook computer. The turnover cylinder 16 is used to drive the screen of the notebook computer to turn over and open. During processing, when the pushing cylinder 14 works, the two sides of the notebook computer abut against the pushing block 15 and the positioning frame 13 respectively; then the turnover cylinder 16 is controlled to work, the negative pressure suction disc 18 is driven to move towards the notebook computer, until the negative pressure suction disc 18 abuts against the back of the screen of the notebook computer, and the negative pressure suction disc 18 will adsorb the back of the screen of the notebook computer; then the turnover cylinder 16 is controlled to reset, the negative pressure suction disc 18 is driven to move away from the notebook computer, the negative pressure suction disc 18 will pull the screen of the notebook computer to rotate relative to the keyboard, until the turnover cylinder 16 resets; then the negative pressure device connected to the negative pressure suction disc 18 stops negative pressure suction. Through the turnover cylinder 16 and the negative pressure suction disc 18, the notebook computer can be turned over and opened to a fixed angle, so that each notebook computer can be opened to a fixed angle before testing, which improves the accuracy and stability of the test.

[0042] The first base 12 is provided with a code scanning head 19 near one side of the pushing cylinder 14. The code scanning head 19 is used to identify the identification code on the notebook computer on the first conveying line 11. Before the notebook computer is tested, a two-dimensional code will be displayed on the screen of the notebook computer. During the specific processing process, when the negative pressure suction cup 18 opens the notebook computer to a proper angle, the two-dimensional code on the screen can be scanned by the code scanning head 19, so that the notebook computer is connected with the control center of the test assembly line, so that the control center can control the notebook computer to be tested. After the code scanning head 19 completes the scanning, the pushing cylinder 14 is controlled to reset, and the pushing block 15 is driven to move away from the notebook computer, so that the pushing block 15 is separated from the notebook computer. Then the first conveying line 11 is controlled to work, and the notebook computer is sent to the second conveying line 21 through the material passing gap 81.

[0043] As shown in Figure 6 The loudspeaker test device 200 includes a second base 22, and the second conveying line 21 is fixedly installed on the second base 22. The second conveying line 21 is provided with a first blocking assembly 23 and a first clamping and positioning assembly 24. The first blocking assembly 23 is used to limit the notebook computer on the second conveying line 21, so that each notebook computer can stop at a uniform position on the second conveying line 21, thereby improving the consistency of the test. The first clamping and positioning assembly 24 is used to abut against both sides of the notebook computer, so that the notebook computer is limited and fixed on the second conveying line 21, so as to test the loudspeaker and keyboard resonance of the notebook computer, thereby improving the stability and accuracy of the test. The second base 22 is provided with a sound pickup assembly 25. The sound pickup assembly 25 is used to pick up the sound played by the loudspeaker when the notebook computer works or the vibration sound of the keyboard when the notebook computer works. During the test, the control center controls the notebook computer on the second conveying line 21 to play an audio file, and the corresponding sound can be picked up by the sound pickup assembly 25, so as to judge whether the loudspeaker performance and the keyboard resonance of the notebook computer are qualified.

[0044] In order to improve the accuracy of the test, a noise pickup microphone 26 is further arranged on the second base 22, and the noise pickup microphone 26 is arranged on the second base 22 away from the second conveying line 21. The noise pickup microphone 26 is used to pick up the noise in the protective cover 80 of the loudspeaker test device 200, and feed back the noise information to the control center. The sound picked up by the sound pickup assembly 25 after the noise is eliminated by the software algorithm of the control center is the sound played by the loudspeaker or the resonance sound of the keyboard. By obtaining the noise and offsetting, the accuracy of the test can be improved.

[0045] Specifically, as shown in Figure 7As shown, the second conveying line 21 comprises two conveying frames 211 arranged in parallel, the conveying frames 211 are connected with the second base 22, and each conveying frame 211 is provided with a conveying belt 212. The second base 22 is provided with a conveying driving assembly 213 for driving the conveying belt 212 to move. The conveying driving assembly 213 is a motor pulley structure, and the motor drives the pulley to rotate, thereby driving the conveying belt 212 to move on the conveying frame 211, so as to drive the notebook computer to move. The second base 22 is also provided with a conveying adjusting mechanism 214 for adjusting the distance between the two conveying frames 211. The conveying adjusting mechanism 214 is a motor screw structure, and the motor drives the screw to rotate, thereby driving one of the conveying frames 211 to move towards or away from the other conveying frame 211, so that the distance between the two conveying frames 211 changes, and the distance between the two conveying belts 212 changes synchronously, so that it can adapt to the test requirements of notebook computers of different sizes.

[0046] In order to adapt to the test requirements of notebook computers of different sizes, the conveying frame 211 is provided with a blocking adjusting mechanism 27 for adjusting the position of the first blocking assembly 23. The blocking adjusting mechanism 27 is a motor screw structure, and the first blocking assembly 23 is installed on the output end of the blocking adjusting mechanism 27. By controlling the motor to work, the first blocking assembly 23 can be driven to move on the conveying frame 211 in a direction parallel to the movement direction of the conveying belt 212, so that the first blocking assembly 23 can block the notebook computer of different sizes on the conveying belt 212 at a position aligned with the pickup assembly 25, so that the pickup assembly 25 can test the loudspeaker performance and keyboard resonance of the notebook computer.

[0047] The first blocking assembly 23 comprises a blocking cylinder 231 installed on the output end of the blocking adjusting mechanism 27. The output end of the blocking cylinder 231 is provided with a blocking block 232. The blocking cylinder 231 can drive the blocking block 232 to move in a direction perpendicular to the movement direction of the conveying belt 212, and make the blocking block 232 extend into or out of the conveying belt 212. Normally, the blocking cylinder 231 is extended, so that the blocking block 232 extends into the conveying belt 212. When working, the conveying belt 212 drives the notebook computer to move. When the notebook computer moves to the corresponding position of the blocking block 232, the blocking block 232 abuts against one end of the notebook computer, so that the conveying belt 212 cannot drive the notebook computer to move any more. At this time, the notebook computer is just moved to a position aligned with the pickup assembly 25. After the pickup assembly 25 completes the test, the blocking cylinder 231 is controlled to retract, driving the blocking block 232 to disengage from the notebook computer. Then the conveying belt 212 can drive the notebook computer to move, and transport it to the third conveying line 500.

[0048] The first clamping positioning assembly 24 comprises clamping cylinders 241 symmetrically arranged on the two conveying frames 211, one clamping cylinder 241 is arranged on each conveying frame 211, and the two clamping cylinders 241 are oppositely arranged, and a clamping block 242 is arranged on the output end of each clamping cylinder 241. During testing, after the blocking block 232 blocks the notebook computer, the conveying belt 212 is controlled to stop working; then the two clamping cylinders 241 are controlled to work, the clamping blocks 242 are driven to move towards the conveying belt 212, until the two clamping blocks 242 abut against the two sides of the notebook computer respectively, the notebook computer is clamped by the two clamping blocks 242, so that it cannot move again; then the loudspeaker of the notebook computer plays audio, and then the loudspeaker performance and the keyboard resonance performance of the notebook computer are tested by cooperation of the sound pickup assembly 25 and the bottom noise pickup microphone 26; after the testing is completed, the clamping cylinders 241 are controlled to reset, and the blocking cylinders 231 are controlled to retract, so that the blocking block 232 and the two clamping blocks 242 are separated from the notebook computer respectively; then the notebook computer is conveyed to the third conveying line 500 by the conveying belt 212.

[0049] As shown in Figure 8 , the sound pickup assembly 25 comprises 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 arranged above the second conveying line 21 respectively, and the third sound pickup mechanism 253 is arranged below the second conveying line 21. Different types of notebook computers can be installed in different positions, and 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 simultaneously or partially called, which is not limited in the application.

[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 described herein.

[0051] Specifically, as shown in Figure 9 , the third sound pickup mechanism 253 comprises a longitudinal driving module 2531, the longitudinal driving module 2531 is connected with the second machine base 22, a transverse driving module 2532 is arranged on the output end of the longitudinal driving module 2531, a microphone mounting block 2533 is arranged on the output end of the transverse driving module 2532, and a sound pickup microphone 2534 is arranged on the microphone mounting block 2533. During specific operation, because the positions of the loudspeakers of various types of notebook computers are not the same, the longitudinal driving module 2531 can drive the transverse driving module 2532 and the sound pickup microphone 2534 to move longitudinally, and the transverse driving module 2532 can drive the sound pickup microphone 2534 to move transversely, so that the position of the sound pickup microphone 2534 can move freely in a two-dimensional plane, thereby meeting the testing requirements of different types of notebook computers.

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

[0053] In this embodiment, the horizontal drive module 2532 is equipped with two microphones 2534. The lead screw on the horizontal drive module 2532 is a bidirectional lead screw, which can drive the two microphones 2534 to move closer together or further apart. Since many laptops have two symmetrically arranged speakers, setting up two microphones 2534 can simultaneously pick up the sound from both speakers, thereby improving the accuracy and convenience of testing.

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

[0055] The structure of the fan noise testing device 300 is the same as that of the speaker testing device 200, and the specific structure of the fan noise testing device 300 will not be described in detail here. During fan noise testing, the control center of the production line controls the laptop to operate normally. Through the cooperation of the microphone 2534 and the background noise microphone 26, and through the software algorithm of the control center, the fan noise of the laptop during operation can be obtained, thereby determining whether the fan noise of the laptop is within the acceptable range, thus realizing the fan noise testing process for the laptop.

[0056] like Figure 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 its structure will not be described in detail here. A second blocking component 43 and a second clamping and positioning assembly 44 are mounted on the sixth conveyor line 41. The second blocking component 43 is used to limit the laptop computer to the sixth conveyor line 41, ensuring that each laptop computer can stay at a uniform position on the sixth conveyor line 41, thus improving the consistency of the test. The second blocking component 43 has the same structure as the first blocking component 23, so its structure will be described in detail here. The second clamping and positioning assembly 44 is used to hold the laptop computer against both sides to test the microphone performance and airtightness of the laptop computer, improving the stability and accuracy of the test.

[0057] The second clamping positioning assembly 44 is similar to the first clamping positioning assembly 24 in structure, and the difference is that the second clamping assembly has three clamping cylinders 241 which are distributed in a triangular shape on both sides of the sixth conveying line 41; in operation, the three clamping cylinders 241 work simultaneously to drive the corresponding clamping blocks 242 to move, and the notebook computer is clamped and fixed on the sixth conveying line 41 by the three clamping blocks 242 pressing against the two sides of the notebook computer.

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

[0059] The third machine base 42 is further provided with a first hole plugging mechanism 47 and a second hole plugging mechanism 48, the first hole plugging mechanism 47 is arranged above the sixth conveying line 41, and the second hole plugging mechanism 48 is arranged on one side of the sixth conveying line 41, and the first hole plugging mechanism 47 and the second hole plugging mechanism 48 are respectively used to plug the sound hole of the notebook computer on the sixth conveying line 41. According to the different microphone installation positions of different notebook computers, the first hole plugging mechanism 47 or the second hole plugging mechanism 48 can be controlled to work, and the sound hole of the notebook computer is plugged by the first hole plugging mechanism 47 or the second hole plugging mechanism 48, so as to test the air tightness of the microphone of the notebook computer on the sixth conveying line 41.

[0060] In specific testing, after the sixth conveying line 41 conveys the notebook computer to the corresponding position of the second blocking assembly 43, the notebook computer is blocked on the sixth conveying line 41 by the second blocking assembly 43; then the notebook computer is clamped and fixed by the second clamping positioning assembly 44. Then the first loudspeaker 45 and / or the second loudspeaker 46 is controlled to play test audio, and the microphone of the notebook computer on the sixth conveying line 41 picks up the audio information and feeds it back to the control center, and the control center can judge whether the microphone performance of the notebook computer is normal. Then the first hole plugging mechanism 47 or the second hole plugging mechanism 48 is controlled to work, and the sound hole of the notebook computer on the sixth conveying line 41 is plugged by the first hole plugging mechanism 47 or the second hole plugging mechanism 48, and then the first loudspeaker 45 and / or the second loudspeaker 46 plays test audio, and the microphone of the notebook computer on the sixth conveying line 41 picks up the audio information and feeds it back to the control center, and the control center can judge whether the air tightness of the microphone of the notebook computer is qualified by comparing the two data when the sound hole is plugged and when the sound hole is not plugged.

[0061] It should be noted that the microphone of the notebook computer mainly has the following distribution modes:

[0062] 1. The microphone is installed on the side of the display screen of the notebook computer, and is usually installed on the side of the camera of the notebook computer.

[0063] 2. The microphone is installed below the mouse of the notebook computer, and is usually installed on the inner side of the bottom shell of the notebook computer.

[0064] Usually, the first plugging mechanism 47 is used for testing the air tightness of the microphone of the above-mentioned first notebook computer; and the second plugging mechanism 48 is used for testing the air tightness of the microphone of the above-mentioned second notebook computer.

[0065] As shown in Figure 11 , the first plugging mechanism 47 comprises a plugging lifting module 471, which is fixedly installed on the third machine base 42 and is a motor lead screw structure. A clamping jaw air cylinder 472 is installed on the output end of the plugging lifting module 471, and two silica gel clamping heads 473 are arranged on the output end of the clamping jaw air cylinder 472. When testing the air tightness of the microphone of the above-mentioned first notebook computer, the plugging lifting module 471 is controlled to work, the clamping jaw air cylinder 472 is driven to descend, and the two silica gel clamping heads 473 are moved to the two sides of the microphone of the notebook computer. Then the clamping jaw air cylinder 472 is controlled to work, the two silica gel clamping heads 473 are driven to approach each other, and the notebook computer is clamped by the two silica gel clamping heads 473, so that the sound hole of the notebook computer is plugged. Then the first loudspeaker 45 and / or the second loudspeaker 46 are controlled to play test audio, so as to test the air tightness of the microphone of the notebook computer. After the test is completed, the clamping jaw air cylinder 472 is controlled to work, the two silica gel clamping heads 473 are driven to separate, and then the plugging lifting module 471 is controlled to reset, so that the silica gel clamping heads 473 are lifted and reset to the initial position.

[0066] As shown in Figure 12As shown, in order to adapt to the processing requirements of different sizes of notebook computers, the third base 42 is provided with a hole plugging adjustment module 49 for driving the second hole plugging mechanism 48 to move horizontally. The hole plugging adjustment module 49 can drive the second hole plugging mechanism 48 to move horizontally on the third base 42, and the driving direction of the hole plugging adjustment module 49 is perpendicular to the movement direction of the sixth conveying belt 212. The hole plugging adjustment module 49 has a motor lead screw structure, and the specific structure is not described herein. The second hole plugging mechanism 48 includes a hole plugging mounting block 481, and the hole plugging mounting block 481 is provided with two hole plugging cylinders 482. One of the hole plugging cylinders 482 is horizontally arranged, and the other is arranged obliquely. Because the shapes of the housings of notebook computers are different, if the housing of a notebook computer is a right-angle structure, the horizontally arranged hole plugging cylinder 482 can be controlled to work; if the housing of a notebook computer is an oblique-angle structure, the obliquely arranged hole plugging cylinder 482 can be controlled to work. The output ends of the two hole plugging cylinders 482 are respectively provided with silica gel plugs 483, and the hole plugging cylinders 482 can drive the corresponding silica gel plugs 483 to abut or separate from the notebook computer on the sixth conveying line 41. Before testing the air tightness of the microphone of the above-mentioned second type of notebook computer, the hole plugging adjustment module 49 is controlled to drive the second hole plugging mechanism 48 to move horizontally on the third base 42 until the second hole plugging mechanism 48 can be connected with the notebook computer on the sixth conveying line 41. During the testing process, the corresponding hole plugging cylinder 482 is controlled to work to drive the silica gel plug 483 to move, so that the silica gel plug 483 abuts against the sound hole of the notebook computer on the sixth conveying line 41, and seals the sound hole of the notebook computer. Then the first loudspeaker 45 and / or the second loudspeaker 46 are controlled to play test audio, so as to test the air tightness of the microphone of the notebook computer. After the test is completed, the hole plugging cylinder 482 is controlled to reset, and the silica gel plug 483 is driven to move away from the notebook computer and reset to the initial position.

[0067] As Figure 2As shown, the receiving assembly 700 includes a receiving rack 71 fixedly connected with the third base 42, one end of the receiving rack 71 being communicated with the discharging end of the sixth conveying line 41, a plurality of rotatable rollers 72 being installed on the receiving rack 71, and a baffle 73 being installed on the side edge of the receiving rack 71. The rollers 72 are arranged to reduce the friction of the notebook computer on the rollers 72 after the notebook computer is discharged from the third base 42 by the sixth conveying line 41, so as to protect the appearance of the product. The baffle 73 is arranged to prevent the notebook computer from falling out of the receiving rack 71, thereby improving the safety of the test. After the test is completed, the sixth conveying line 41 discharges the tested product from the third base 42, and then the notebook computer on the rollers 72 is taken away by the operator or the mechanical arm, so as to complete the discharging. In other embodiments, the receiving assembly 700 can be replaced by a conveying belt. The tested product is directly sent into the conveying belt by the sixth conveying line 41, and the product is conveyed to the next work station by the conveying belt, so as to realize the unmanned automatic test process.
