[0036] Working principle: When in use, the staff inserts the circuit board body 9 from the through hole 7 on the limit plate 1 6. When the circuit board body 9 is against the limit plate 2 8 through the limit groove 2 5 on the support plate 4, the staff fixes the circuit board body 9. At this time, when the staff puts all the components on the entire support column 3 into the limit groove 1 206 on the conveyor belt 205, the staff starts the motor 1 202 to drive the rotating roller 1 203 to rotate, thereby driving the conveyor belt 205 to move. At this time, the conveyor belt 205 passes through the rotating roller 209, which ensures that the conveyor belt 205 will not collapse, thereby improving the overall stability. The staff promptly starts the cylinder 1102 on the correction component 11, so that the cylinder 1102 is raised and lowered according to the height of the conveyor belt 205. When it is raised and lowered to a suitable position, the staff starts the motor 2 1107 to drive the positive and negative double-ended screw rod 1108 to rotate, thereby driving the two sets of sliding seats 1111 to move at the same time. When the correction roller 1113 contacts the conveyor belt 205, the correction roller 1113 corrects the conveyor belt 205, thereby ensuring that the conductive slurry is accurately injected into the conductive hole 7, improving the accuracy of the plugging hole, and at the same time, in the continuous production process, even if there is a slight position deviation, the correction component 11 can quickly Adjustments are made to avoid continuous accumulation of errors and ensure that each conductive hole 7 can receive high-quality plugging treatment. When the circuit board body 9 moves to the bottom of the plugging assembly 12, the staff pours the conductive slurry into the slurry storage tank, connects the pressure pump and the plugging nozzle, turns on the control system, sets the pressure of the pressure pump, the injection speed of the plugging nozzle and the movement parameters of the positioning mechanism, and then the staff starts the motor three 1203 to rotate the active bevel gear 1204, thereby driving the driven bevel gear 1205 to rotate. At the same time, the staff starts the cylinder two 1208 and stops when it is lifted to the appropriate position. At this time, multiple plugging holes are The nozzle 1214 performs multi-directional spraying by rotating the ball 1213 to ensure stable plugging quality. When all the holes are plugged, the pressure pump and the plugging nozzle 1214 are turned off. At this time, all the plugging work has been completed. At this time, the staff only needs to return the conveyor belt 205 to the initial position and take out the plugged circuit board body 9 from the through hole 7. The staff only needs to repeat the above process to plug all the circuit board bodies 9. Finally, the staff only needs to clean the conductive slurry storage tank and the plugging nozzle 1214 to prepare for the next use. The structure is simple, the operation is easy, and the practicability is high.
