When the microcontroller is transmitted to the bottom of the visual inspection device 3 on the conveyor belt, the position of the visual inspection CCD camera 301 is adjusted so that it can comprehensively shoot and inspect the surface of the microcontroller.

[0033] During the operation of the entire microcontroller inspection production line, each device works in coordination. The transmission device 2 continuously and stably transmits the microcontroller, the visual inspection device 3 first inspects the surface of the microcontroller, and then the clamping device 4 clamps the defective microcontroller according to the inspection results. The flipping device 5 flexibly flips the microcontroller according to the inspection requirements, and finally the laser inspection device 6 inspects the back of the microcontroller. After the monitoring is completed, the microcontroller is stacked on the stacking device 1, achieving the purpose of efficiently and comprehensively inspecting the microcontroller on a production line.

[0034] Working process

[0035] The transmission motor 201 of the transmission device 2 is started, and its output shaft drives the rotating shaft 203 to rotate via the pulley. The first pulley 204 on the rotating shaft 203 rotates accordingly, and since the first pulley 204 is connected to multiple sets of parallel second pulleys 205 via belts, the transmission belt is driven to run, so that the microcontroller is transmitted on the transmission belt. Multiple sets of first pulleys 204 and second pulleys 205 ensure that the transmission belt is evenly stressed, ensuring the stability of the microcontroller during the transmission process.

[0036] When the microcontroller is transferred to the bottom of the visual inspection device 3, the visual inspection CCD camera 301 in the visual inspection device 3 starts to work. The visual inspection CCD camera 301 and the transmission device 2 slide in multiple directions, and its position can be adjusted in the following ways: the X-axis motor 303 at the end of the first transmission track 302 drives the first slide 304 to slide in the X-axis direction, the Y-axis motor 305 on the side of the first slide 304 drives the first sliding assembly 306 to slide in the Y-axis direction, and the second slide 314 is driven by the Z-axis motor 307 to slide in the Z-axis direction. After the visual inspection CCD camera 301 obtains the image information on the surface of the microcontroller, it detects whether there are defects such as scratches, cracks, stains, etc. on the surface of the microcontroller through relevant image processing algorithms.

[0037] The clamping device 4 works (for defective microcontrollers). If the visual inspection finds that the microcontroller is defective, the clamping device 4 will reject it. The motor at the top of the first housing 11 in the clamping device 4 drives the third slide bar group 13, and the third slider 14 on the third slide bar group 13 slides on the slide bar. The first telescopic cylinder 15 fixed at the lower end of the third slider 14 drives the clamping claw 9 to move. The clamping claw 9 can accurately clamp the defective microcontroller and then remove the defective product from the production line.

[0038] When the microcontroller needs to switch the detection surface, for example, when the back circuit solder joint detection needs to be performed after the surface defect detection, the rotating air gripper 10 in the flipping device 5 (for the microcontroller after the surface defect detection) works, and the second telescopic cylinder 17 at the upper end of the connecting member 21 drives the fourth slider 19 to slide along the Y-axis direction on the second slide rail 20 to the specified position, and the rotating air gripper 10 can clamp the microcontroller, and then rotate itself, thereby driving the microcontroller to flip, realizing the conversion of the detection surface, and facilitating the back circuit solder joint detection.

[0039] When the microcontroller is transmitted to the bottom of the laser detection device 6, the laser detection device 6 starts to work. The laser detector 601 in the laser detection device 6 detects the circuit on the back of the microcontroller, such as whether the circuit is connected, whether there is a short circuit, etc. At the same time, the solder joint detection CCD camera 610 on the fixing part 604 at the bottom of the laser fixing plate 603 takes pictures and detects the solder joints on the back of the microcontroller, and determines whether the solder joints are full and whether there are defects such as cold solder joints through image analysis technology, thereby comprehensively detecting the back of the microcontroller.

[0040] The clamping device 4 works (for defective microcontrollers). If the laser detection device 6 finds that there are defects on the back of the microcontroller, the clamping device 4 will remove it. The motor on the top of the first housing 11 of the clamping device 4 drives the third slide bar group 13, and the third slider 14 on the third slide bar group 13 slides on the slide bar. The first telescopic cylinder 15 fixed at the lower end of the third slider 14 drives the clamping claw 9 to move. The clamping claw 9 can accurately clamp the defective microcontroller and then remove the defective product from the production line.

[0041] The rotating air gripper 10 in the flipping device 5 (for the microcontroller after the back circuit solder joint detection) works, and the second telescopic cylinder 17 at the upper end of the connecting piece 21 drives the fourth slider 19 to slide to the specified position along the Y-axis direction on the second slide rail 20. The rotating air gripper 10 can clamp the microcontroller and then rotate itself, thereby driving the microcontroller to flip, realizing the conversion of the detection surface, and facilitating the stacking of the microcontroller.

[0042] When the transmission device 2 transmits the microcontroller to the position of the upward cylinder 101, the upward cylinder 101 transports the microcontroller upward to contact the supporting fastener 104, and the supporting fastener 104 rotates around the first rod group 102 until the microcontroller enters the stacking slot 103, and the supporting fastener 104 recovers to contact the second rod group 105, and the microcontroller is supported on the supporting fastener 104. The transmission device 2 enables the microcontroller to enter the stacking slot 103 in an orderly manner.

[0043] During the whole process, various devices work together, and the transmission device 2 continuously and stably transmits the microcontroller, thereby achieving the purpose of efficiently and comprehensively testing the microcontroller on a production line.

[0044] In summary, the present invention can realize the integration of microcontroller detection equipment and achieve orderly stacking of microcontrollers after detection.
