[0054] Step S11: The conveyor belt transports the wood to a CT scanning module, where the emission intensity is Q n The scanning instrument measures the condition of the wood by emitting a beam and observing the degree of absorption of the beam.

[0055] Step S12: After emitting the light beam, monitor its light intensity W n , and the residual light intensity E is obtained n , ;

[0056] Step S13: Refine the absorption amount of each beam of light, calculate the area where the absorption exceeds the threshold R, and fit the above node area into a closed figure. The nodes of wood are generally darker in color and have a stronger ability to absorb light beams, so the beam node range is calculated based on the method of light beam absorption exceeding the threshold;

[0057] Step S14: Remove the light in the area where the absorption exceeds the threshold R in the wood image, calculate the average intensity E0 of the remaining light, and thus obtain the density T of the wood board. , the density of wood is generally different. The situation of wood nodes is eliminated and the residual light intensity of the remaining area is calculated to make the calculation more accurate. The higher the density of wood, the less light absorption, but the density of wood has an upper limit and will not exceed a certain value;

[0058] Step S15: The density information of each wooden board and the wood nodes are coded accordingly and stored in the database.

[0059] Step S2 further comprises the following steps:

[0060] Step S21: The primary production module receives the wood raw material, reads the wood code, and obtains the data information of the wood in the database;

[0061] Step S22: According to the density of the wood, the robot arm selects different rotation speeds Y. , the higher the density of the wood, the slower the screw will be turned, so the work done is higher and the screw will be more firmly screwed into the wood;

[0063] Step S24: The robot arm drills the screws vertically according to the rotation speed Y to connect the furniture together. Drilling the screws vertically can avoid the occurrence of insufficient connection.

[0066] Step S32: The module analyzes the side view and analyzes the concave deformation angle U on both sides of the wood and the screw. According to the degree of concave of the wood on both sides of the screw, it can be checked whether the screw is vertical. When it is vertical, the screw connection is more secure.

[0067] Step S33: If the deformation angles U are the same, the screw is in a vertical state, otherwise it is in a non-optimal state;

[0068] Step S34: transmitting the furniture connection in a non-optimal state to the component correction module.

[0069] Step S4 further comprises the following steps:

[0070] Step S41: the component correction module reads the connection side scan image;

[0071] Step S42: Calculate the direction I of the force applied by the robot arm according to the deformation angle U of the wooden board on both sides of the screw. , I is to adjust the direction of U toward one end of the deformed protrusion.
