[0025] Please refer to Figures 1-6, the PCB board glue overflow detector, including a lifting device 2, and a detection device 1 is arranged at the top of the lifting device 2.

[0026] In this embodiment: The detection device 1 includes a fixed frame 101. Two side detection platforms 102 are symmetrically arranged on the front and back surfaces of the fixed frame 101. Side cameras 103 are installed on the side detection platforms 102. A track blocking cylinder 104 is arranged in the middle of the fixed frame 101. A cylinder head 105 is arranged at the top of the track blocking cylinder 104. Two first lead screws 106 are symmetrically and rotatably arranged on both sides of the fixed frame 101. A first motor 107 is installed at the front end of the first lead screw 106. A moving frame 108 is arranged in the middle of the first lead screw 106. Synchronous belts 109 are arranged on the front side of the moving frame 108 and the inner side of the fixed frame 101. A second motor 110 is installed in front of the synchronous belt 109. Four front cameras 111 are symmetrically installed on the top of the fixed frame 101. A transmission belt 112 is arranged between the two first lead screws 106. The first lead screw 106 is connected to the fixed frame 101 by bearings. The first motor 107 is connected to the first lead screw 106 by a flat key. The side camera 103 is connected to the side detection platform 102 by bolts. The cylinder head 105 is rectangular. The fixed frame 101 supports the second motor 110 and at the same time drives the synchronous belts 109 on the fixed frame 101 and the moving frame 108 to move, driving the PCB board to be detected to move linearly. At the same time, the track blocking cylinder 104 ejects the cylinder head 105, and the cylinder head 105 blocks the movement of the PCB board, making it just located in the center of the side camera 103 and the front camera 111. Then the side detection platform 102 supports the side camera 103 to scan the front and back sides of the PCB board, and the fixed frame 101 supports the front camera 111 to scan the left and right sides of the PCB board. The six cameras simultaneously check whether there is glue overflow on the side of the PCB board through software and transmit the results to the host computer. After the detection is completed, the fixed frame 101 supports the first motor 107 to drive the coaxial first lead screw 106 to rotate. The first lead screw 106 drives the other first lead screw 106 to rotate through the transmission belt 112. The two first lead screws 106 simultaneously drive the moving frame 108 to move backward, so that the PCB board on the synchronous belt 109 loses the bottom support. Through the design of simultaneously scanning the four sides of the PCB board by the side camera 103 and the front camera 111, it is convenient to shorten the scanning time required, improve the detection speed of the device. At the same time, using software to control the camera for scanning can also improve the scanning accuracy, reduce errors. The overall automation degree of the device is high, and the processing smoothness is good;

[0028] Working principle: During detection, the electrical box 4 is responsible for the overall power supply, the light-blocking shell 3 blocks the light to form a closed room for camera scanning, the fixed frame 101 supports the second motor 110 and drives the synchronous belt 109 on the fixed frame 101 and the mobile frame 108 to move, driving the PCB board to move in a straight line, and at the same time, the track blocking cylinder 104 pops out the cylinder head 105, and the cylinder head 105 blocks the movement of the PCB board so that it is just located in the center of the side camera 103 and the front camera 111, and the rear inspection table 102 supports the side camera 103 to scan the front and back sides of the PCB board, and the fixed frame 101 supports the front camera 111 to scan the left and right sides of the PCB board. The six cameras simultaneously check whether there is glue overflow on the side of the PCB board through software, and transmit the results to the host. After the detection is completed, the fixed frame 101 supports the first motor 107 to drive the coaxial first screw 106 to rotate The first lead screw 106 drives another first lead screw 106 to rotate through the transmission belt 112, and the two first lead screws 106 drive the movable frame 108 to move backward at the same time, so that the PCB board on the synchronous belt 109 loses its bottom support. At the same time, the fixed seat 201 supports the third motor 203 to drive the second lead screw 202 to rotate, driving the lifting platform 204 to rise, pushing the clamp seat 205 and the limit clamp 206 to rise to undertake the PCB board that has lost its support, and finally the limit clamp 206 drives the PCB board to descend to complete the unloading process.
