[0049] Working principle of this embodiment: Bamboo sticks are placed on the top of the bamboo stick conveyor belt 1, and the bamboo sticks are located between the outer limit bumps 101. The bamboo stick conveyor belt 1 rotates cyclically by a motor. The bamboo stick conveyor belt 1 drives the bamboo sticks to the lower part of the upper vision camera module 2. The upper vision camera module 2 records the real-time images of the bamboo sticks below and transmits them to the middle AI calculation module 106. The middle AI calculation module 106 identifies the bamboo sticks in the images of the upper vision camera module 2, identifies defective features such as burrs in the bamboo sticks. The calculation hardware module in the middle AI calculation module 106 cooperates with the software algorithm model to continuously calculate and summarize in image recognition, continuously improve and accelerate the recognition degree, realize the acceleration of the moving speed of the bamboo stick conveyor belt 1, realize the improvement of the detection efficiency, and the bamboo stick conveyor belt 1 and the outer limit bumps 101 cooperate to carry out the stable conveying of bamboo sticks. During the conveying process of the bamboo sticks by the bamboo stick conveyor belt 1, the bamboo sticks move to the lower part of the lower wedge block 203. The bottom of the lower wedge block 203 is in contact with the bamboo sticks on the top of the bamboo stick conveyor belt 1. The lower wedge block 203 guides the bamboo sticks to rotate circumferentially, and the bamboo sticks are adjusted and turned over circumferentially. The upper vision camera module 2 realizes the recording, transmission and detection of the comprehensive real-time images of all positions of the bamboo sticks, avoiding the situation of detection omission on the side of the bamboo stick against the upper vision camera module 2, and improving the accuracy of the appearance quality detection of the bamboo sticks; The lower wedge blocks 203 on both sides of the lower connecting bracket 201 are arranged in a staggered front and back manner. During the conveying process of the bamboo sticks, the two lower wedge blocks 203 are in contact with the bamboo sticks in sequence, and the two lower wedge blocks 203 do not contact the bamboo sticks at the same time, avoiding the situation of detection omission caused by the bamboo sticks being blocked by the two lower wedge blocks 203 when the two lower wedge blocks 203 contact the bamboo sticks at the same time. When the head end of the bamboo stick contacts the lower wedge block 203, the detection process of the tail end of the bamboo stick is carried out. When the tail end of the bamboo stick contacts the other lower wedge block 203, the detection process of the head end of the bamboo stick is carried out, ensuring that the upper vision camera module 2 can clearly and comprehensively capture the appearance information of the bamboo sticks and improving the reliability of visual detection;
[0050] The bamboo sticks on the top of the bamboo stick conveyor belt 1 are conveyed to the lower part of the upper pressure module 3. The outer detection pressure block 301 contacts and applies pressure to the bamboo sticks on the top of the bamboo stick conveyor belt 1. The outer detection pressure block 301 presses down the bamboo sticks. The outer detection pressure block 301 tests the strength of the bamboo sticks by applying a downward pressure. The outer detection pressure block 301 rotates at the same speed as the upper pressure module 3 and the bamboo stick conveyor belt 1, and the strength detection is carried out synchronously during the conveying process of the bamboo sticks, eliminating the waiting time of the bamboo sticks during the detection process, realizing the continuous detection of the bamboo sticks, greatly improving the detection efficiency, and meeting the detection requirements of large-scale bamboo stick production;
[0051] The middle turntable bracket 302 meshes and drives the middle screw rod 303 to rotate. The threads of the middle screw rod 303 guide the moving slider 304 to move axially. The moving slider 304 moves and pushes the supporting elastic member 305 closer to the outer detection pressure block 301. The length of the supporting elastic member 305 is reduced, the pressure on the outer detection pressure block 301 increases, and the downward pressure of the outer detection pressure block 301 on the bamboo stick increases, realizing flexible adjustment of the detection pressure for the strength of the bamboo stick, enabling the detection system to adapt to the pressure requirements of bamboo sticks with different strength specifications, improving the versatility of the detection system, and meeting the production quality detection requirements of bamboo sticks with different specifications; the lower vision camera module 4 records the images of the outer detection pressure block 301 and the bamboo stick and transmits them to the middle AI calculation module 106. The inclination angle of the lower vertical carriage 401 and the tail end of the lower vision camera module 4 are fixed. The vertical position of the lower horizontal carriage 403 and the lower vertical carriage 401 is fixed. The horizontal position of the lower horizontal carriage 403 and the lower base 404 is fixed. The lower vision camera module 4 realizes position adjustment in the inclination angle, vertical, and horizontal directions, ensuring that the outer detection pressure block 301 and the bamboo stick are at the center position of the image screen. For the bent bamboo stick judged by the middle AI calculation module 106, the middle AI calculation module 106 controls the discharge telescopic cylinder 104 to drive the upper moving discharge plate 103 to move horizontally. After the upper moving discharge plate 103 approaches the bamboo stick conveyor belt 1, the bamboo sticks on the bamboo stick conveyor belt 1 directly move to the top of the upper moving discharge plate 103. After the upper moving discharge plate 103 moves away from the bamboo stick conveyor belt 1, the bamboo sticks on the bamboo stick conveyor belt 1 move to the lower fixed discharge plate 105, realizing the separation of qualified and unqualified bamboo sticks.
