[0050] A positioning component 12 is provided at one end of the transmission line unit 3 .

[0051] The adjustment component 8 includes a first linear module 81, a slide rail 82, a slide seat 83 and a locking screw 84. The first linear module 81 is arranged on the machine platform 1. The first linear module 81 is arranged along the length direction of the avoidance through hole 4. The slide rail 82 is vertically connected to the first slider on the first linear module 81. The slide seat 83 is slidably connected to the slide rail 82. The slide seat 83 is provided with a locking hole. The locking screw 84 is arranged in the locking hole. The second detection component 7 is arranged on the slide seat 83. The space below the detection working surface can be fully utilized. At the same time, the first linear module can drive the slide rail to move along the length direction of the avoidance through hole through the slider thereon. The slide seat can be moved up and down on the slide rail by loosening and tightening the locking screw to adjust the position of the second CCD camera, thereby improving the detection quality of the second CCD camera.

[0052] The second detection component 7 includes a first CCD camera 71, a fill light 72, a light source controller and a brightness sensor. The first CCD camera 71 is mounted on the slide 83. The first CCD camera 71 is connected to the light source controller. An anti-collision plate 9 is arranged above the first CCD camera 71. The anti-collision plate is connected to the slide rail 82. A through hole is arranged on the anti-collision plate 9. The first CCD camera 71 faces the through hole. The fill light 72 is mounted on the anti-collision plate 9. The brightness sensor is arranged on the fill light 72. The anti-collision plate can prevent materials from falling from above and damaging the camera, thereby protecting the camera. Since the first CCD camera is located inside the machine, when the bottom plate passes through the avoidance through hole, the light will be blocked, resulting in unclear images of the first CCD camera. The brightness sensor senses the light intensity around the first CCD camera, and the light intensity of the fill light is controlled by the light source controller, so that the first CCD camera can capture a clear image, thereby achieving the purpose of improving the detection quality.

[0053] The first detection component 6 includes a second CCD camera 61, a manipulator 62 and a mounting seat 63. The manipulator 62 is arranged on the top of the machine 1, and the mounting seat 63 is connected to the manipulator 62. At least one second CCD camera 61 is arranged on the mounting seat 63. Two second CCD cameras are provided and arranged in parallel; the second CCD camera is connected to the machine through a manipulator, and the manipulator is a multi-axis manipulator, which can realize the movement of the second CCD camera up and down, left and right, front and back, and can also realize the adjustment of the angle, so that the second CCD camera can be aligned with the detection position on the bottom plate, thereby improving the detection quality.

[0054] In one embodiment, the second CCD camera 61 is arranged at the center of the mounting seat 63, and light absorbing plates 10 are respectively arranged on both sides of the second CCD camera 61, and the light absorbing plates 10 are connected to the mounting seat 63. The light absorbing plates can absorb the light of the second CCD camera, reduce reflections, and improve the quality of the second CCD camera.

[0055] In another embodiment, a light-shielding dark box 11 is provided on the mounting seat 63, and the second CCD camera 61 is built in the light-shielding dark box 11.

The light-shielding dark box shields the external light source, avoids reflection and light leakage, and improves the detection effect and stability.

[0056] The inner surface of the light-shielding dark box 11 is provided with a light-absorbing layer, which is a black coating and can improve the light-absorbing effect and prevent the reflected light of the bottom plate from being reflected again.

[0057] The positioning component 12 includes a second linear module 121, a connecting plate 122 and a push plate 123. The second linear module 121 is arranged on the machine table 1. Two second sliders are arranged on the second linear module 121. The connecting plate 122 is connected to the second slider, and the push plate 123 is connected to the connecting plate 122. The second linear module can drive the connecting plate to move through the second slider thereon, so that the two push plates can push the bottom plate to the detection position, realizing automatic positioning with high efficiency.

[0058] One end of the push plate 123 is provided with a baffle 13. The end of the bottom plate can be limited, thereby improving the quality of positioning.

[0059] A sensor 14 is provided on one side of the push plate 123, and the sensor is installed on the machine 1. The sensor is used to sense the product on the conveyor line, and after the sensor senses the product on the conveyor line, the second linear module starts to work.

[0060] Working principle: The bottom plate is automatically sent to the detection area through the transmission line unit, and then the first CCD camera and the second CCD camera take pictures of the bottom plate, and finally the photographed information is sent to the computer for processing to determine whether the bottom plate is qualified. Therefore, the transmission line of the present invention is composed of two transmission line units, the two transmission line units are belt transmission lines, the two transmission line units are independently controlled, and the two transmission line units can forward or reverse the flow direction, so that the movement direction can be flexibly adjusted for operation, which is convenient for use in different areas. An avoidance through hole is opened on the detection working surface, and the gap between the avoidance through hole and the transmission line unit is directly opposite. When the bottom plate passes through the gap, the first detection component above the gap and the second detection component below the gap can detect the upper and lower sides of the bottom edge at the same time, which can improve the detection efficiency. The second CCD camera is connected to the machine through a manipulator. The manipulator is a multi-axis manipulator, which can realize the movement of the second CCD camera up and down, left and right, front and back, and can also realize the adjustment of the angle, so that the second CCD camera can be aligned with the detection position on the bottom plate, thereby improving the detection quality. The first CCD camera is installed below the detection working surface through an adjusting component. The adjusting component consists of a first linear module, a slide rail, a slide seat and a locking screw. The first linear module can drive the slide rail to move along the length direction of the avoidance through hole through the slider thereon.
