Description

Technical Field

[0001] The present invention relates to the technical field of automated testing, and particularly to multi-station automated testing equipment. Background Art

[0002] A wireless earphone is a form of earphone that uses radio waves instead of wires. Components such as a microphone and a speaker are integrated on a flexible circuit board inside it. Due to quality requirements, after the production of the flexible circuit board for wireless earphones, tests for frequency response and microphone effect need to be carried out.

[0003] However, in order to protect the sound holes from dust pollution, a protective film is attached to the speaker after the production of the flexible circuit board. During the testing stage, this protective film needs to be torn off, and after the testing is completed, the protective film needs to be reattached. The addition of the film tearing and film attaching steps has increased the steps in the testing stage, and the size of the flexible circuit board is small, resulting in inconvenient operation. In addition, the transfer of the flexible circuit board after the speaker film is torn off between testing devices increases the risk of dust polluting the sound holes. These problems have led to poor efficiency and accuracy in the testing of flexible circuit boards by existing testing equipment.

[0013] Compared with the prior art, the beneficial effects that the present invention can achieve are: 1. The present invention integrates functions of equipment loading, film tearing, frequency response testing, film pasting and unloading. After the loading tray containing the product to be tested is placed from the material inlet, the whole process is realized as unmanned operation through the manipulator assembly, synchronous belt drive system and intelligent control module, significantly shortening the test cycle. The structures between mechanisms are compact and the layout is reasonable, improving the test efficiency.

[0014] 2. The indexing cam mechanism of the present invention is combined with the multi-station design, and can parallelly complete film tearing and testing of multiple products within the same cycle. Compared with the traditional single-station equipment efficiency, it is especially suitable for the production line of large quantities of flexible circuit boards for wireless earphones.

[0015] 3. The present invention ensures the position accuracy of the product to be tested during transportation and testing through the code scanning and positioning component. Combined with the visual positioning of the manipulator, the picking error can be controlled within a very small range, avoiding test failure caused by position deviation, and is especially suitable for high-precision test scenarios of micro flexible circuit boards.

[0016] 4. The test process of the present invention is implemented in a relatively enclosed machine table, and with the wind dust removal device, it effectively isolates the interference of external dust on the sound holes and the test process. After film tearing, the product to be tested directly enters the shielding environment for testing, avoiding the sensitivity deviation caused by dust adhesion in traditional manual transportation, and improving the reliability of the test results.

[0017] 5. The present invention adopts a modular design. For example, the loading and unloading channels, test table board and film pasting components can be independently disassembled or replaced. For example, by adjusting the size of the loading tray material slot or replacing the probe module, different specifications of flexible circuit boards can be quickly adapted to meet the co-line test requirements of multiple models of products, reducing the cost of repeated equipment investment.

[0018] 6. Through the sample products preset in the sample carrier tray of the present invention, the equipment can regularly grab the sample products through the manipulator to perform the full-process test, compare with the preset parameters to judge the equipment status, timely detect problems such as probe wear or sensor drift, ensure the test consistency during long-term operation, and reduce the defective rate of product batches.

The products to be tested can be loaded and unloaded from the front and rear positions respectively. The loading and unloading flow channels 14 include flow channel columns 15. The flow channel columns 15 are connected to the bottom surface of the loading and unloading platform 13. A material tray support frame 16 is slidably connected through a sliding bearing, and a material tray 17 is supported on the material tray support frame 16. A plurality of material slots 18 for placing the product to be tested are evenly provided on the surface of the material tray 17. The bottom end of the flow channel column 15 is connected to an upper and lower material rack 19. The upper and lower material racks 13 are provided with openings for taking and placing materials at positions corresponding to the upper and lower material racks 19. The upper and lower material racks 19 are rotatably installed with a screw rod 20 between the two flow channel columns 15.

A code scanning and positioning assembly 38 is arranged at the position of the loading and unloading platen 13 corresponding to the CDD shooting hole. The code scanning and positioning assembly 38 includes a camera body 39 and a light source fixing plate 40. The camera body 39 uses a CCD camera. The light source fixing plate 40 is fixedly connected above the camera body 39. The code scanning and positioning assembly 38 is connected below the CDD shooting hole through a lens clamping block.

[0029] Specifically, before the manipulator assembly 12 transfers and picks up the product to be tested, the product to be tested is moved onto the code scanning and positioning assembly 38. The code scanning and positioning assembly 38 scans and positions the product to be tested through the camera body 39 to ensure the accuracy of the position of the product to be tested during picking and the traceability of the test results, so as to ensure the stability and accuracy in the subsequent test stage. The multi-axis manipulator 118 combines the nozzle position adjustment motor 123 with the CCD vision positioning to correct the picking position in real time and avoid the grasping failure caused by the size difference of the material tank 18.

[0030] Such as Figure 7 、 Figure 8 and Figure 14As shown in the figure, a test table board 41 and a test table board 42 are connected in the test area. The test table board 41 and the test table board 42 are connected in a left-right distribution. Round holes are provided on the front and rear sides of the test table board 41, and turntables 43 are rotatably installed in the round holes. An air rotary joint 44 is installed at the center of the turntable 43. The air rotary joint 44 is a known technology in the art. It has a rotating end and a fixed end. The fixed end is used for air path connection. The rotating end of the air rotary joint 44 is connected to the turntable 43, and the air paths of the fixed end and the rotating end are communicated. A plurality of air pipe interfaces are provided on the rotating end. The air rotary joint 44 is used to provide air path connection for the air-using equipment on the turntable 43. A bottom side column 45 is connected to the bottom surface of the test table board 41 corresponding to the position of the turntable 43. The bottom end of the bottom side column 45 is connected to an installation table 46. A divider 47 for driving the rotation of the rotating part of the air rotary joint 44 is installed on the installation table 46. A base 48 is annularly connected to the turntable 43. The number of bases 48 is at least four and they are annularly installed on the turntable 43. A carrier 49 is installed on the base 48. A carrier slot for placing the product to be tested is provided on the carrier 49. A common carrier plate 50 is connected to the base 48. A top side column 51 is connected to the top surface of the test platform corresponding to the position of the turntable 43. The top end of the top side column 51 is connected to a cylinder plate 52. Two upper die cylinders 53 are installed on the cylinder plate 52. The transmission shaft of the upper die cylinder 53 is connected to an upper die fixing plate 54. A guide rod 55 is fixedly connected to the upper die fixing plate 54. The guide rod 55 is slidably connected to the cylinder plate 52 through a sliding bearing. The bottom end of the upper die fixing plate 54 is connected to an expansion column 56. The bottom end of the expansion column 56 is connected to an operation plate 57. A pressing head assembly 58 and an upper frequency response assembly 62 are respectively arranged on the two operation plates 57. A film tearing assembly 126 and a lower frequency response assembly 81 are respectively arranged on the installation plate corresponding to the positions of the pressing head assembly 58 and the upper frequency response assembly 62. The number and positions of the pressing head assembly 58, the upper frequency response assembly 62, the film tearing assembly 126 and the lower frequency response assembly 81 correspond to the carrier slots on the carrier 49.

[0031] Specifically, after the manipulator assembly 12 picks up the material, it places the product to be tested into the loading slot of the carrier table 49. The divider 47 drives the turntable 43 to rotate by a quarter turn. The product to be tested first enters the position corresponding to the pressing head assembly 58. The upper die cylinder 53 drives the upper die fixing plate 54 to descend, so that the operation plate 57 abuts against the common carrier plate 50. The pressing head assembly 58 presses the product to be tested in the loading slot to make it stable. The film tearing assembly 126 tears off the protective film of the speaker of the product to be tested. After tearing the film, the upper die cylinder 53 drives the operation plate 57 to rise. The divider 47 drives the turntable 43 to rotate by another quarter turn. At this time, the product to be tested corresponds to the position of the upper frequency response assembly 62. The upper die cylinder 53 drives the operation plate 57 to descend again. The upper frequency response assembly 62 and the lower frequency response assembly 81 test the sensitivity of the product to be tested at a specific frequency, such as 1 kHz. After the test is completed, the upper die cylinder 53 drives the operation plate 57 to rise again. The divider 47 drives the turntable 43 to rotate by another quarter turn, completing the film tearing and frequency response tests of the product to be tested. The manipulator assembly 12 takes out the tested component in the carrier table 49. It should be noted that during the waiting process of film tearing and testing, the manipulator assembly 12 continues to pick up and place the product to be tested in the carrier table 49, so that each quarter turn of the turntable 43 will have a product to be tested for loading, unloading, film tearing and frequency response testing. The turntable 43 divider 47 drives four workstations to synchronously perform film tearing, frequency response testing, film pasting and unloading, realizing parallel processing. Compared with traditional single-station equipment, the test efficiency is improved, and the pneumatic slip ring 44 design ensures uninterrupted transmission of the air circuit signal.

[0032] As Figure 7 and Figure 9 shown, the pressing head assembly 58 includes a pressing head cylinder 59. The pressing head cylinder 59 is installed on the operation plate 57. The transmission shaft of the pressing head cylinder 59 is connected with a pressing head mounting block 60. The pressing head mounting block 60 is connected with a film tearing pressing head 61. The film tearing pressing head 61 penetrates through the operation plate 57. The film tearing pressing head 61 corresponds to the loading slot and also corresponds to the position of the speaker of the product to be tested.

[0033] Specifically, when the pressing head cylinder 59 is started, it drives the film tearing pressing head 61 to descend, pressing and fixing the speaker of the product to be tested in the carrier table 49 to ensure the stability of the film tearing operation of the film tearing assembly 126.

[0034] As Figure 7 and Figure 10As shown, the film tearing assembly 126 includes a film tearing table 127. A guide rail is connected to the mounting table 46. The film tearing table 127 is slidably connected to the guide rail. A positioning cylinder 128 is installed on the mounting table 46. The transmission shaft of the positioning cylinder 128 is connected to the film tearing table 127. The positioning cylinder 128 is used to adjust the front and rear positions of the film tearing table 127. The mounting table 46 is connected with receiving plates 129 on both sides of the film tearing table 127. A tape roll 130 and a waste film reel 131 are respectively rotatably connected to the two receiving plates 129. A motor for driving the waste film reel 131 to rotate is installed on the receiving plate 129. The tops of the receiving plates 129 are connected to each other through a receiving baffle 132. One side of the receiving baffle 132 is connected with a tape cover plate 133. A floating plate is slidably installed on the bottom surface of the tape cover plate 133. One end of the tape on the tape roll 130 is connected to the waste film reel 131, and the tape is sleeved between the tape cover plate 133 and the floating plate. The adhesive surface of the tape faces downward. The tabletop of the film tearing table 127 is installed with a main film tearing cylinder 134. A secondary film tearing cylinder 135 is installed at the rear end of the main film tearing cylinder 134. The transmission shafts of the main film tearing cylinder 134 and the secondary film tearing cylinder 135 are both installed with suction vacuum tubes 136 through a support plate. Through holes for film tearing are provided on the base 48 and the carrier 49.

[0035] Specifically, connect the suction vacuum tube 136 to the negative pressure pipeline controlled by a solenoid valve. The positioning cylinder 128 pushes the film tearing table 127 to the position corresponding to the through hole. The main film tearing cylinder 134 and the secondary film tearing cylinder 135 rise to make the suction vacuum tube 136 pass through the through hole and adsorb the protective film of the speaker of the product to be tested. Then the main film tearing cylinder 134 and the secondary film tearing cylinder 135 descend, and the protective film is torn off by using negative pressure. The positioning cylinder 128 pulls the film tearing table 127 back to the original position. Then the main film tearing cylinder 134 and the secondary film tearing cylinder 135 lift the suction vacuum tube 136 to make the protective film adhere to the tape. Then the suction vacuum tube 136 disconnects the negative pressure. The main film tearing cylinder 134 and the secondary film tearing cylinder 135 pull the suction vacuum tube 136 down. The motor drives the waste film reel 131 to rotate, so that the part of the tape with the adhered protective film leaves the film tearing position and is gradually wound on the waste film reel 131. Through the double-action film tearing of negative pressure adsorption and tape peeling, it is ensured that the protective film is completely peeled off and there is zero residue of waste film.

[0036] Such as Figure 7 、 Figure 11 and Figure 12As shown, the upper frequency response component 62 includes a frequency response bottom plate 63, which is connected to the operation panel 57.

[0037] Specifically, the sound source unit of the input sound and the circuit that converts the sound into an electrical signal and transmits it to the decoding board are respectively connected to the horn socket and the plug-in terminal, and then connected to the upper adapter terminal 79 and the floating probe 78 respectively. After the operating table is lowered, the upper adapter terminal 79 is inserted into the lower adapter needle mold 137, and the floating probe 78 and the probe 80 are in contact with the circuit of the flexible circuit board of the product to be tested. The key motor 66 drives the motor slider 67 to rise and fall, thereby driving the sensor baffle 68 to rise and fall. The sensor baffle 68 is used to drive the induction switch 70 to control the start and stop of the frequency response test function. The sound source generates sound, and the MIC on the product to be tested receives the sound, and then converts the sound into an electrical signal and transmits it to the decoding board, thereby testing the sensitivity of the product to be tested at a specific frequency and the quality of the parts.

[0038] like Figure 8 and Figure 14As shown in the figure, the lower frequency response component 81 includes a jacking cylinder 82. A test hole is provided on the bottom surface of the carrier slot, and the test hole penetrates through the carrier table 49 and the base 48. The transmission shaft of the guide post cylinder is connected to a column plate 83. A positioning guide post 84 is connected to the column plate 83 at a position corresponding to the test hole, and a sound guide post 85 is connected to the column plate 83 at a position corresponding to the through hole. The top end of the sound guide post 85 is connected to a conductive rubber pad.

[0039] Specifically, the jacking cylinder 82 pushes the column plate 83 to rise, so that the sound guide post 85 contacts the speaker to receive sound, and the positioning guide post 84 jacks up the flexible circuit board to cooperate with the floating probe 78 to clamp the product to be tested, increasing the stability of the test.

[0040] As Figure 7 、 Figure 15 and Figure 16 shown in the figure, MIC test components 86 are provided on both the front and rear sides of the test table board two 42. The MIC test component 86 includes a rectangular test box frame 87. A test circuit based on PLC control is provided inside the test box frame 87.

The transmission shaft of the sliding cylinder 90 is connected to the door connecting plate 89. Test box covers are installed on all six sides of the test box frame 87, and sliding holes are provided at the top ends of the test box covers on the left and right sides. The door connecting plate 89 is located inside the sliding holes and is connected to an SL shielding box 91. A code scanning and positioning component 38 is provided on the test table board two 42 between the two test box frames 87. A test board 92 is connected inside the test box frame 87. One end of the test board 92 close to the code scanning and positioning component 38 is connected to an acoustic test table 93. An opening is provided on the test box cover corresponding to the acoustic test table 93. Guide rails are connected to the top surface of the test board 92, and an in-box sliding plate 94 is slidably connected to the guide rails. The top surface of the in-box sliding plate 94 is connected to a shaft fixing plate 95 through a column. Two upper moving cylinders 96 are provided on the shaft fixing plate 95. The two upper moving cylinders 96 are distributed left and right. The transmission shafts of the upper moving cylinders 96 are connected to an adapter plate 97. The top surface of the adapter plate 97 is slidably connected to the shaft fixing plate 95 through a rigid shaft. A separate speaker is provided on the adapter plate 97 and is controlled by the test circuit. A standard microphone is provided inside the acoustic test table 93. A support electric slide 98 is installed inside the test box frame 87. The transmission shaft of the support electric slide 98 is connected to the in-box sliding plate 94.

[0041] Specifically, the manipulator assembly 12 places the product to be tested on the acoustic test bench 93. Then, the transmission shaft of the sliding cylinder 90 extends, and the door connecting plate 89 pushes the SL shielding box 91 to cover the product to be tested and closes the test box cover plate, thus avoiding the influence of external noise on the test. Then, the bracket electric sliding table 98 pushes the inner box sliding plate 94 to make the connecting plate 97 correspond to the product to be tested. The upper moving cylinder 96 descends and pushes the connecting plate 97 closer to the product to be tested. The speaker on the connecting plate 97 emits sound to the mic of the product to be tested, and the standard microphone in the acoustic test bench 93 receives the sound emitted by the speaker of the product to be tested, thereby verifying and testing the mic function of the product to be tested. After the test is completed, the MIC test assembly 86 resets, and the manipulator assembly 12 takes the product to be tested. It should be noted that before placing the product to be tested on the MIC test assembly 86 and after taking the product, the manipulator assembly 12 needs to pass through the position detection of the code scanning and positioning assembly 38.

[0042] As Figure 7 and Figure 17 shown, on one side of the MIC test assembly 86 on the test bench plate two 42, there is also a film pasting assembly 99. The film pasting assembly 99 includes a film pasting frame 100. The top of the film pasting frame 100 is connected with an electric sliding table 101. The transmission end of the electric sliding table 101 is connected with a film taking frame 102. At one end of the film taking frame 102 far from the electric sliding table 101, a film feeding cylinder 103 is installed. The transmission shaft of the film feeding cylinder 103 is installed with a rotating cylinder 104. The transmission shaft of the rotating cylinder 104 is connected with a film sucking frame 105. At the upper and lower ends of the film sucking frame 105, suction nozzle vacuum guide blocks 106 are installed. At the end of the suction nozzle vacuum guide block 106, a suction nozzle is installed. On one side of the film pasting frame 100, a film position adjusting cylinder 107 is installed.

On the transmission shaft of the film feeding plate 108, a tape shaft 109 and a tape winding shaft 110 are rotatably installed. A tape with film 111 is connected to the tape shaft 109. The tape with film 111 is a tape with a protective film adhered to the adhesive surface. On the protective film, film bodies adapted to the shape of the speaker are arranged in a die-cut manner. On the film feeding plate 108, a motor and a synchronous belt assembly for driving the tape shaft 109 and the tape winding shaft 110 to rotate are installed. The top of the film feeding plate 108 is connected with a separating block 112 for separating the protective film and the tape. A tape pressing block 113 is connected to the separating block 112. On the top of the film feeding plate 108, on one side of the separating block 112, an anti-sticking block 114 is connected. The anti-sticking block 114 is made of iron fluorocarbon plating material. The tape passes through between the separating block 112 and the tape pressing block 113, and the tape is separated from the protective film at the end of the separating block 112. One end of the tape is connected to the tape winding shaft 110, and the protective film is placed on the anti-sticking block 114. On one side of the film pasting frame 100, a film shooting lens 115 for detecting the position of the film body is installed. On one side of the film pasting assembly 99 on the test bench plate two 42, a code scanning and positioning assembly 38 is provided.

[0043] Specifically, the electric slide table 101 pushes the nozzle vacuum guide block 106 to move above the anti-sticking block 114. The nozzle at the end of the nozzle vacuum guide block 106 sucks the die-cut protective film. Then, the rotating cylinder 104 drives the film suction frame 105 to rotate half a circle, and another nozzle sucks another protective film. Then, the electric slide table 101 pulls the nozzle vacuum guide block 106 back to its original position. After the manipulator assembly 12 grabs the product to be tested, the product to be tested is placed above the nozzle vacuum guide block 106 after being detected by the code scanning and positioning assembly 38. Then, the transmission shaft of the film feeding cylinder 103 extends to push the nozzle vacuum guide block 106 to rise, so that the protective film fits onto the speaker of the product to be tested, and the speaker of the product to be tested is film-coated. After film coating, the film feeding cylinder 103 drives the nozzle vacuum guide block 106 to return to its original position, and the rotating cylinder 104 drives the film suction frame 105 to rotate half a circle to film coat the next product to be tested. After film coating is completed, the above actions are repeated to suck the protective film. After the protective film is needed, the motor drives the tape take-up shaft 110 to rotate, and the film tape 111 runs to supplement the new protective film.

[0046] As Figure 1 and Figure 18 shown, the transfer manipulator assembly 12 is arranged on both sides and in the middle of the test table board two 42. The manipulator assembly 12 includes a transfer frame 117. A multi-axis manipulator 118 is installed at the end of the transfer frame 117. The multi-axis manipulator 118 is a known prior art. A material taking frame 119 is connected to the end of the multi-axis manipulator 118. A material taking CCD camera 120 is installed in the middle of the material taking frame 119. Material taking cylinders 121 are installed on both sides of the material taking frame 119. The transmission shaft of the material taking cylinder 121 is connected to a motor frame 122. A nozzle position adjusting motor 123 is installed on the motor frame 122. The transmission shaft of the nozzle position adjusting motor 123 is connected to a nozzle frame 124. Two material taking vacuum nozzles 125 are connected to the bottom end of the nozzle frame 124.

[0047] Specifically, the multi-axis manipulator 118 can drive the material-taking vacuum suction nozzle 125 to move horizontally and vertically, bringing the material-taking vacuum suction nozzle 125 close to the product to be tested. The lifting of the material-taking cylinder 121 enables the material-taking vacuum suction nozzle 125 to quickly grasp the product to be tested. The nozzle position adjustment motor 123 can adjust the axial position of the material-taking vacuum suction nozzle 125. The material-taking vacuum suction nozzle 125 can perform negative pressure suction on both ends of the product to be tested, ensuring stable clamping of the flexible circuit board.

[0048] It should be noted that the movement of the structure of the present application can be detected by setting sensor switches and sensors, and the limit is achieved through circuit control. This is common knowledge and is shown in the drawings of the present application, so it will not be elaborated in this application.
