If the top surface of the furniture panel is detected to be qualified, the furniture panel is unloaded through the belt conveyor mechanism 6. If the top or bottom surface of the furniture panel is detected to be unqualified, the unqualified furniture panel is sent to the unqualified product area through the belt conveyor mechanism 6.

[0023] Furthermore, the scanning component 3 includes a linear guide rail 31, which is horizontally arranged at one end of the gantry 1, and its two ends are fixedly connected to the two sides of the gantry 1 respectively, and a mounting plate 32 is installed on the sliding seat of the linear guide rail 31, a first motor 33 is provided at one end of the mounting plate 32, and a scanning plate 34 is provided at the other end, and the scanning plate 34 is transmission-connected to the output shaft of the first motor 33, and the scanning plate 34 extends to above the belt conveyor mechanism 6, and a plurality of fill lights 35 and a plurality of cameras 36 are provided on its surface.

[0024] In this embodiment, a linear guide rail 31 using prior art can drive a mounting plate 32 mounted on a sliding seat to move horizontally, thereby driving a scanning plate 34 to move horizontally from one side of the furniture board to the other side. During the movement, a plurality of cameras 36 (using prior art CCD cameras) are used to detect defects on the surface of the furniture board. The surface of the furniture board is illuminated by a fill light 35, thereby facilitating the camera 36 to detect the surface of the furniture board.

The slider 43 is horizontally arranged in the slide groove 8, and it is threadedly connected to the screw rod 41, and it is slidably connected to the optical axis 44.

[0028] In this embodiment, the second motor 42 drives the screw rod 41 in the slide groove 8 to rotate, so that the slider 43 moves horizontally in the slide groove 8, thereby driving the vacuum suction cup machine 5 at the bottom end of the slider 43 to move, and the optical axis 44 is used to improve the stability of the slider 43 when moving.

[0031] Furthermore, a collection bin 7 is provided at one end of the frame 2 away from the scanning assembly 3 .

[0032] In this embodiment, when a defect is detected on the bottom surface of the furniture board, the electric push rod cooperates with the vacuum suction cup machine 5 to place the furniture board on the belt conveyor mechanism 6, and the belt conveyor mechanism 6 is started to transport the unqualified furniture board in the opposite direction of the material feeding direction until the furniture board falls into the collection bin 7; when a defect is detected on the top surface of the furniture board, the belt conveyor mechanism 6 is started to transport the unqualified furniture board in the opposite direction of the material feeding direction until the furniture board falls into the collection bin 7; a slope can be set between the belt conveyor mechanism 6 and the collection bin 7 to facilitate the unqualified furniture board to enter the collection bin 7;

[0033] Qualified furniture boards are transported to the downward direction by the belt conveyor mechanism 6 .

[0034] The utility model relates to a defect detection device for furniture panels. The device performs defect detection on the bottom end of the panel adsorbed by a vacuum suction cup machine through a camera on a scanning board, and then drives the scanning board to rotate through a first motor, thereby performing defect detection on the top end of the panel placed on a belt conveyor mechanism. Thus, defect detection can be performed on both sides of the panel in a panel unloading process, and workers do not need to perform visual identification, thereby improving the efficiency of panel surface defect detection and reducing the labor intensity of workers.
