The process steps are as follows,

(1) Conveying and feeding: Multiple roller heads on the first conveyor belt rotate synchronously, and after placing the wood board with burrs on the first conveyor belt, the wood board is conveyed to the centering adjustment module under the action of the rollers;

(2) Coarse centering adjustment: The wood board is conveyed by the roller, and it will pass through multiple sets of side-by-side iron sheets that are in the shape of "eight" on both sides and are perpendicular to the surface of the roller. The closer the fine adjustment mechanism is, the smaller it is, and the initial centering adjustment of the board posture is gradually performed;

(3) Fine adjustment of centering: After step 2, the wooden board will be finely adjusted to the position and posture of four pairs of guide wheels symmetrical to the center line of the workbench. Under the action of the spring contraction and the synchronous rotation of the two gears, each pair of The guide wheel keeps the board on the centerline of the workbench;

(4) Burr detection: The centering board reaches the shooting position under the action of the first and second conveyor belts, and the trigger sensor receives the signal to trigger the industrial camera to perform image acquisition. The image acquisition card collects the image information and uploads it to the microcomputer for calibration and correction. , grayscale processing, and then calculate the effective border width and burr position of the burr sawn timber;

(5) Saw position control: After step 4, according to the position of the board on the worktable, the size of the burr, and the effective area, the burr removal position and the decomposition position are obtained, and the stepper motor is driven to drive the lead screw to rotate, and the lead screw drives the lead screw to slide. The toggle plate of the block push rod mechanism pushes the saw blade forward or backward to adjust the lower saw position;

(6) Sawing decomposition: The wood board enters the sawing mechanism under the action of the third conveyor belt, and is sawed by the three circular saw blades together, and the burrs are separated from the effective area of the wood board;

(7) Sorting and recycling: The sawed boards and burrs are sent to the sorting module. According to the position of the effective board on the worktable, two independent drive motors drive the screw of the screw group to rotate to push the screw forward or backward. The rod slider is set to the set position, and the drive bridge slide table is mounted on the lead screw slide block. The effective wood board enters the discharge conveyor belt along the drive bridge slide table under the action of the conveyor belt, and the burrs do not catch the drive bridge slide table. fall into the waste recycling chute;

(8) Board output: Two effective boards arrive at the output end under the action of the discharge conveyor belt.
