[0025] Embodiment 1:

[0026] Please refer to Figures 1 to 3 , a wooden board defect detection and sorting device provided by the present utility model includes: a first conveyor belt 6 and a second conveyor belt 10 arranged side by side; the first conveyor belt 6 and the second conveyor belt 10 are connected to each other, and there is a gap at the connection; a wooden board image defect collection device is arranged at the connection of the first conveyor belt 6 and the second conveyor belt 10; a feeding device is arranged at one end of the first conveyor belt 6 away from the second conveyor belt 10, and a control terminal 19 is arranged on the side of the first conveyor belt 6; a sorting device is arranged on the second conveyor belt 10; the signal output end of the wooden board image defect collection device is connected to the signal receiving end of the control terminal 19; the signal output end of the control terminal 19 is connected to the signal receiving end of the sorting device; the wooden board image defect collection device is used to detect the defects of the wooden boards provided by the feeding device and transmit the detection information to the control terminal 19, and the control terminal 19 is used to control the sorting device to sort and classify the wooden boards according to the detection information.

[0027] The feeding device places the wooden boards to be detected on the first conveyor belt 6, and the first conveyor belt 6 conveys the wooden boards to the connection of the first conveyor belt 6 and the second conveyor belt 10. The wooden boards are subjected to defect detection by the wooden board image defect collection device at the connection and the detection information is transmitted to the control terminal 19. The wooden boards continue to be transported to the second conveyor belt 10, and the control terminal 19 controls the sorting device on the second conveyor belt 10 to sort and classify the wooden boards according to the detection information, realizing the automatic detection of the wooden boards, improving the detection efficiency, and at the same time unifying the detection standards, thereby improving the detection accuracy.

[0028] In this embodiment, the feeding device includes: a feeding bin 5 arranged above the end of the first conveyor belt 6; a top material cylinder 1 and a pushing material cylinder 2 arranged vertically on the side of the feeding bin 5 away from the second conveyor belt 10.

[0029] The two sides of the square feeding bin 5 are equal in side width to the first conveyor belt 6. A rectangular groove for pushing out the wooden board is provided at the bottom of the feeding bin 5. The wooden board pushing cylinder 2 controls its pushing rod 4 to push the wooden board at the bottom of the feeding bin 5 onto the first conveyor belt 6. The pusher cylinder 1 controls its pusher rod 3 to hold the wooden board above the bottommost wooden board to prevent the pushing cylinder 2 from pushing out multiple wooden boards at once.

[0030] In this embodiment, the wooden board image defect acquisition device includes: a first annular backlight board 9 provided above the connection of the first conveyor belt 6 and the second conveyor belt 10, and a second annular backlight board 17 provided below the connection of the first conveyor belt 6 and the second conveyor belt 10; a first STINGRAY camera 8 is provided above the first annular backlight board 9; a second STINGRAY camera 18 is provided below the second annular backlight board 17.

[0031] The first STINGRAY camera 8 and the second STINGRAY camera 18 can collect images of the upper and lower surfaces of the wooden board and detect defects on the front and back sides of the wooden board; the first annular backlight board 9 and the second annular backlight board 17 can irradiate the light source on the upper and lower surfaces of the wooden board, thereby better collecting images;

[0032] In this embodiment, the sorting device includes: a first sorting cylinder 11, a second sorting cylinder 12, and a third sorting cylinder 13 sequentially arranged on the second conveyor belt 10; a first collection bin 16, a second collection bin 15, and a third collection bin 14 are arranged on the side of the second conveyor belt 10; the first sorting cylinder 11, the second sorting cylinder 12, and the third sorting cylinder 13 correspond to the first collection bin 16, the second collection bin 15, and the third collection bin 14 in sequence in the width direction of the second conveyor belt 10.

[0033] The first collection bin 16, the second collection bin 15, and the third collection bin 14 are classified, and wooden boards of the same quality are collected in each collection bin. After the wooden board image defect acquisition device detects the defects of the wooden board and transmits the detection information to the control terminal 19, the control terminal 19 analyzes the data, determines which level of wooden board the wooden board belongs to, and when the wooden board moves to the second conveyor belt 10, controls the sorting cylinder corresponding to the collection bin of the corresponding level to push the wooden board into the corresponding collection bin, thereby completing the sorting of the wooden board; and when the wooden board needs to stay on the conveyor belt, the control terminal 19 can also control the first conveyor belt 6 or the second conveyor belt 10 to stop working; in this way, not only can the surface information of the wooden board be accurately obtained, analyzed and processed to detect defects, but also the defective wooden boards can be sorted quickly and accurately, greatly improving the work efficiency.

[0034] In this embodiment, the size of the gap 20 between the first conveyor belt 6 and the second conveyor belt 10 in the conveying direction is smaller than the size of the wooden board provided by the feeding device in the conveying direction.

[0035] As Figure 2 shown, no wooden board is placed at the gap 20. By limiting the size of the gap 20 at the connection, it is avoided that the wooden board falls when it moves to the gap 20.

[0036] In this embodiment, the first annular backlight panel 9, the second annular backlight panel 17, the first STINGRAY camera 8 and the second STINGRAY camera 18 are all fixed on the fixing frames on the sides of the first conveyor belt 6 and the second conveyor belt 10 through the fixing rods 7, so as to improve the stability of the first annular backlight panel 9, the second annular backlight panel 17, the first STINGRAY camera 8 and the second STINGRAY camera 18.

[0037] In this embodiment, the moving directions of the first sorting cylinder 11, the second sorting cylinder 12 and the third sorting cylinder 13 are the same as the width direction of the second conveyor belt 10, so that the first sorting cylinder 11, the second sorting cylinder 12 and the third sorting cylinder 13 can accurately push the wooden boards into the corresponding collection bins.

[0038] In this embodiment, the irradiation directions of the first STINGRAY camera 8 and the second STINGRAY camera 18 are perpendicular to the conveying directions of the first conveyor belt 6 and the second conveyor belt 10, so that the first STINGRAY camera 8 and the second STINGRAY camera 18 can irradiate the upper and lower surfaces of the wooden board more clearly.

[0039] In this embodiment, rollers are arranged at the bottoms of the first conveyor belt 6 and the second conveyor belt 10, which facilitates the overall movement of the device.

[0040] Obviously, the above embodiments are only examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
