[0004] However, this existing structure still has the following shortcomings:

[0005] In this technical solution, the PCB board needs to be manually installed onto the test board assembly of the testing device. Then, the corresponding pin insertion board assembly and positioning board assembly are selected, and the conductive probe is pressed down by the clamping machine to make contact with the PCB board and perform power-on testing. This method of testing PCB boards is usually inefficient, requires manual placement of untested PCB boards and removal of PCB boards, and cannot perform continuous testing.

[0029] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0030] See Figures 1 to 10 As shown, an automatic inspection machine for PCB boards of an earphone charging case includes: a machine base 1, on which a loading tray 5 for accommodating PCB boards 100 is provided; several inspection components 2, which are disposed on the machine base 1 and used to inspect the PCB boards 100; a robotic arm module 3, which is disposed on the machine base 1 and used to transfer the PCB boards 100 on the loading tray 5 to the inspection components 2; and a vision module 4, which is disposed between the loading tray 5 and the inspection components 2 and used to visually position the PCB boards 100. The inspection components 2 include a lower mold 21 mounted on the machine base 1 for positioning the PCB boards 100, an upper mold 22 that is vertically movable above the lower mold 21 for testing the PCB boards 100, a pressing cylinder 23 disposed on the inspection components 2 for driving the upper mold 22 to move up and down, and a plug-in / plug-out structure 24 disposed on the machine base 1 for plug-in / plug-out testing with the PCB boards 100.

[0031] In this invention, the detection component 2 is connected to the PCB board 100 via a plug-in structure 24, effectively realizing automatic updating of the PCB board 100's functional software and testing of the PCB board 100's functions. A robotic arm module 3 replaces manual labor in clamping and transferring the PCB board 100 from the loading tray 5 to the detection component 2, effectively saving manpower, achieving continuous detection, and greatly improving efficiency. This invention is suitable for widespread application in various PCB board detection equipment. Furthermore, compared to existing structures, this invention adds a vision module 4, which automatically photographs and scans the QR code on the PCB board 100 before it is placed into the detection component 2, effectively ensuring the accuracy of the PCB board 100's transfer and ensuring it is correctly placed into the lower mold 21. Scanning the QR code obtains product information, facilitating production management.

[0032] The PCB board 100 is equipped with a control button 101 for controlling the working status, several LEDs 102 for displaying the working status, several contacts 103, and a data interface 104. The upper mold 22 is equipped with an analyzer probe 221 for testing the LEDs 102 on the PCB board 100, and a second detection cylinder 222 for testing the pressing of the control button 101. The lower mold 21 is equipped with a probe group 211 for making contact with the contacts 103 on the PCB board 100. Here, when the PCB board 100 is transferred from the loading tray 5 to the lower mold 21 by the robotic arm module 3, the pressing cylinder 23 will drive the upper mold 22 to move downward with the lower mold 21. After moving to the detection position, the analyzer probe 221 will automatically detect the color and brightness of the LED 102 on the PCB board 100. The second detection cylinder 222 will automatically press the control button 101 on the PCB board 100 for detection. At the same time, the probe group 211 will connect with the contact 103 on the PCB board 100 and perform detection.

[0033] The plug-in / plug structure 24 includes a fixed plate 241 disposed on the machine base 1, a first detection cylinder 242 mounted on the fixed plate 241, a slide rail 243 disposed on the fixed plate 241, a slider 244 slidably disposed on the slide rail 243 and connected to the output end of the first detection cylinder 242, and a type-C connector 245 disposed on the slider 244 and used for connecting with the data interface 104. Here, the plug-in / plug-out structure 24 can drive the slider 244 to move back and forth along the slide rail 243 via the first detection motor 242, so as to drive the type-c connector 245 set on the slider 244 to insert / pull out the data interface 104 of the PCB board 100, thereby realizing automatic plugging and unplugging. It can be understood that, generally when the upper mold 22 and the lower mold 21 are closed, the type-c connector 245 is driven to insert into the data interface 104 and the PCB board 100 functional software is automatically burned and tested. After the test is completed, the plug-in / plug-out structure 24 will drive the type-c connector 245 to pull out of the data interface 104 and prepare for the next PCB board 100 test, effectively realizing continuous detection.

[0034] The robotic arm module 3 includes a robotic arm base 31 mounted on the machine base 1, a drive seat 32 mounted on the robotic arm base 31, a first swing arm 33 swayably mounted on the drive seat 32, a second swing arm 34 swayably mounted on the first swing arm 33, a lifting rod 35 vertically mounted on the second swing arm 34, and a suction cup structure 36 connected to the lower end of the lifting rod 35 for moving the PCB board 100. Here, the robotic arm module 3 is located beside the loading tray 5. The robotic arm module 3 drives the first swing arm 33 and the second swing arm 34 via the drive seat 32 to move the suction cup structure 36 to the loading tray 5. Then, the lifting rod 35 drives the suction cup structure 36 to descend above the PCB board 100 and adsorb it. When it swings above the vision component 4, the vision component 4 performs scanning and visual positioning. Then, it is transferred to the detection component 2, where the suction cup structure 36 places the PCB board 100 in the lower mold 21 for detection.

[0035] The suction cup structure 36 includes a connecting seat 361 connected to the lower end of the lifting rod 35, an adjusting cylinder 362 disposed on the connecting seat 361, a support arm 363 disposed at the output end of the adjusting cylinder 362 and driven by the adjusting cylinder 362 to lift and lower, and a suction cup 364 mounted on the support arm 363 for adsorbing the PCB board 100. Here, the adjusting cylinder 362 can control the support arm 363 to make small-amplitude lifting and lowering movements. After the robotic arm module 3 swings to the approximate position, the adjusting cylinder 362 makes fine adjustments, which can effectively improve accuracy and ensure that the suction cup 364 can firmly adsorb the PCB board 100, avoiding accidental drops.

[0036] The machine base 1 is equipped with a protective cover assembly 6 for enhanced protection; the vision module 4 includes a positioning base 41 mounted on the machine base 1, a camera lens 42 mounted on the positioning base 41 for scanning and taking pictures, a cable tray 43 mounted on the camera lens 42, and a supplementary light 44 mounted on the positioning base 41 for supplementary lighting. Here, the supplementary light 44 is ring-shaped and surrounds the camera lens 42 to ensure uniform light, which facilitates scanning by the camera lens 42 and enables visual positioning even in dark environments.

[0037] The machine tool 1 is equipped with a test fixture 7, and the detection components 2 are mounted on the test fixture 7. The test fixture 7 includes a work box 71 detachably mounted on the machine tool 1 for placing the lower mold 21, and a bracket 72 mounted on the work box 71 for placing the pressing cylinder 23. The plug-in structure 24 is also mounted on the work box 71. Here, the test fixture 7 can accommodate multiple detection components 2 and can simultaneously detect multiple PCB boards 100, which can effectively improve work efficiency.

[0038] The upper mold 22 is fitted with a first slide cylinder 223 and a second slide cylinder 224. Correspondingly, a first guide rod 701 and a second guide rod 702 are vertically arranged between the work box 71 and the support 72. The first guide rod 701 and the second guide rod 702 pass through the first slide cylinder 223 and the second slide cylinder 224 respectively, so that the upper mold 22 can be raised and lowered in the vertical direction.

[0039] The feeding tray 5 has several first contour placement positions 51 arranged on it for accommodating the PCB board 100; the machine base 1 is provided with an NG tray 8 for accommodating the PCB board 100, and the NG tray 8 has several second contour placement positions 82 arranged on it for placing the PCB board 100. Here, when the detection component 2 detects a defective product, the robotic arm module 3 places the defective PCB board 100 into the NG tray 8 for easy recycling by the operator.

[0040] In summary, in this invention, the detection component 2 is connected to the PCB board 100 via the plug-in structure 24, effectively realizing automatic software updates and testing of the PCB board 100. The robotic arm module 3 replaces manual labor in clamping and transferring the PCB board 100 from the loading tray 5 to the detection component 2, effectively saving manpower, achieving continuous detection, and greatly improving efficiency. This invention is suitable for widespread application in various PCB board testing equipment. Furthermore, compared to existing structures, this invention adds a vision module 4, which automatically photographs and scans the QR code on the PCB board 100 before it is placed into the detection component 2, effectively ensuring the accuracy of the PCB board 100 transfer and ensuring it is correctly placed into the lower mold 21. Scanning the QR code obtains product information, facilitating production management.
