The blocking block 2063, under the action of the power cylinder 2062, extends between the two conveyor belts to block the circuit board 8. After the circuit board 8 is blocked, the conveyor belt stops running, and the fixed clamping block 2052 moves downward and presses on the circuit board 8 to fix the position of the circuit board 8.
[0055] 5. The second motor 302 of the label feeder 3 (label supporting device) is started, driving the label paper 9 of the unwinding wheel 301 to rotate, so that the label paper 9 is released. Subsequently, the label paper 9 is flattened by the flattening device 304 and moves to the sensor 305. The sensor 305 is connected to the control system 7, such as the PLC control system 7. After the sensor 305 senses that the label on the label paper 9 has passed, it sends a sensing signal to the PLC control system 7, and the PLC control system 7 then outputs a control signal to the second motor 302 of the label feeder 3 according to the program setting, and controls the second motor 302 to stop running. Subsequently, the progressive cylinder 3062 is actuated to push the middle support seat 3064 to move toward the side of the retracting cylinder 3063 until the middle support seat 3064 moves to the extreme position. At this time, the sticky note at the edge of the label paper 9 slightly exceeds the feed line, so that the labeling head 406 can take away the label; at this time, the position of the label to be taken away can be reflected by the pre-set coordinate system;
[0056] 6. According to the preset coordinate system, the control system 7 outputs a control signal to control the actions of various components of the labeling device 4, so that the labeling head 406 moves to the corresponding coordinate and is located above the label to be removed. Then, the labeling head 406 moves downward and removes the label;
[0057] 7. The control system 7 outputs a control signal to control the various components of the labeling device 4 to move the labeling head 406 to the corresponding coordinates and to be located above the position of the circuit board 8 to be labeled. Then, the labeling head 406 moves downward and sticks the label on the circuit board 8;
[0058] 8. The labeled circuit board is conveyed by the conveying device 2 and exits from the circuit board outlet 102 .
