[0019] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0020] like Figures 1-7 As shown, the organic bar appearance inspection device of this utility model includes a bar conveying device, at the outlet of which a collecting hopper 1 is provided. At the outlet of the collecting hopper 1, a receiving drum 2, an end face inspection drum 3, a bar body inspection drum 4, a rejection drum 5, and an output drum 6 are sequentially arranged and connected to each other. At the outlet of the output drum 6, a tray loading machine 7 is provided.

[0021] A first camera 81 for taking pictures of the end face of the organic rod is set near the end face detection drum 3, a second camera 82 for taking pictures of the outer peripheral surface of the organic rod is set near the rod body detection drum 4, and a third camera 83 for taking pictures of the outer peripheral surface of the organic rod is also set near the end face detection drum 3.

[0022] The aforementioned first camera 81 is provided in two sets, with two cameras in each set. The first cameras 81 in the same set are placed at both ends of the end face detection drum 3 to take pictures of the inner and outer end faces of the organic rod. One set of first cameras 81 faces the end face of the target organic rod, while the other set of first cameras 81 forms a certain angle with the rod body of the target organic rod, that is, to take pictures of the end face of the target organic rod at an angle.

[0023] The aforementioned second camera 82 consists of two cameras, arranged side-by-side above the rod detection drum 4, used to detect the lower surface of the target organic rod; the third camera 83 also consists of two cameras, arranged side-by-side below the end face detection drum 3, used to detect the upper surface of the target organic rod. That is, the second camera 82 and the third camera 83 are positioned on either side of the junction of the rod detection drum 4 and the end face detection drum 3, working together to complete the detection and imaging of the entire circumference of the target organic rod.

[0024] The signal output terminals of the first camera 81, the second camera 82, and the third camera 83 are respectively connected to the signal input terminal of the control unit, and the control output terminal of the control unit is connected to the control input terminal of the removal drum 5.

[0025] The aforementioned bar conveying device includes a conveyor belt 9, with multiple input ports arranged side by side on its upstream side that connect to the output end of the bar extruder. The middle part of the conveyor belt has a 180° turning structure, and a collection hopper 1 is provided at the end of the conveyor belt.

[0026] The aforementioned receiving drum 2, end face inspection drum 3, rod body inspection drum 4, rejection drum 5, and output drum 6 are all negative pressure adsorption drums. Among them, such as... Figures 3-6 As shown, the removal drum 5 includes an adsorption rotor 51, in which a negative pressure fixed wheel 52 is slidably fitted. Multiple radial airflow channels 53 are evenly arranged inside the adsorption rotor 51, with the two ends of the airflow channels 53 extending to the wheel surface and wheel hole of the adsorption rotor 51, respectively. A negative pressure groove 54 extending circumferentially is provided on the wheel surface of the negative pressure fixed wheel 52. The length of the negative pressure groove 54 is less than the circumference of the wheel surface of the negative pressure fixed wheel 52, and a removal control groove 55 isolated from it is provided in the negative pressure groove 54. A first negative pressure suction port 56 is provided on the removal control groove 55, and a second negative pressure suction port 57 is provided on the negative pressure groove 54. The first negative pressure suction port 56 and the second negative pressure suction port 57 are respectively connected to an external negative pressure fan. Furthermore, an electromagnetic control valve is provided on the pipe connecting the external negative pressure fan to the removal control groove 55. The receiving drum 2, end face inspection drum 3, rod body inspection drum 4, and output drum 6 are structurally similar to the rejection drum 5, except that the rejection control groove 55 is not set in the negative pressure groove 54 (see Figure 7 Except for the removal drum 5, the rest of the structure is the same as the removal drum 5.

[0027] The control unit includes a control module, an image storage module, an image processing module, and an image comparison and judgment module. The image processing module is used to process the images acquired by the first camera 81, the second camera 82, and the third camera 83, for example, by performing color level processing on the target image using binarization. The image comparison and judgment module is used to compare the image processed by the image processing module with the standard bar image stored in the storage module and to give a judgment result on whether it is a defective bar.

[0028] When working, the external negative pressure fan is started to make the receiving drum 2, the rod body detection drum 4 and the output drum 6 rotate clockwise, and the end face detection drum 3 and the rejection drum 5 rotate counterclockwise; then, the conveying belt 9 is started to convey the 96mm rod bar from the rod bar extruder to the collecting hopper 1, and the rod bar at the outlet of the collecting hopper 1 is tightly adsorbed on the corresponding adsorption rotating wheel 51 of the negative pressure groove 54 under the action of negative pressure of the receiving drum 2; with the adsorption rotating wheel 51 rotating away from the negative pressure groove 54, the negative pressure disappears, and at the same time, the rod bar is tightly adsorbed on the end face detection drum 3 under the action of negative pressure of the end face detection drum 3; since the first camera 81 is fixed, the end face of the rod bar running to the shooting position of the end face detection drum 3 can be shot, and the third camera 82 detects the upper surface of the rod body below the right of the end face detection drum 3, and the fourth camera 83 detects the lower surface of the rod body above the left of the rod body detection drum 4 when the rod bar runs onto the rod body detection drum 4, so that the detection of the whole outer periphery of the rod body is completed. After the above-mentioned cameras finish shooting, the images are transmitted to the image processing module of the control unit, and after the images are processed, the image comparison judgment module judges that the rod bar is a qualified product if the end face and the outer periphery meet the requirements of the standard rod bar, and the rod bar successfully enters the tray loading machine 7 through the rejection drum 5 and the output drum 6; if any one of the end face and the outer periphery does not meet the requirements of the standard rod bar, the image comparison judgment module judges that the rod bar is a defective product, and when the defective product is adsorbed by the rejection drum 5 and runs to the position of the rejection control groove 55, the electromagnetic control valve (the valve is arranged on the pipeline connecting the rejection control groove 55 and the negative pressure fan) receives the instruction sent by the control module, disconnects the connection between the control groove 55 and the negative pressure fan, and makes the defective product separate from the rejection drum 5 under the condition that the negative pressure adsorption is lost, so that the purpose of "rejection" is achieved.

[0029] It should be noted that in the description of the present application, the terms indicating the orientation or position relationship such as "front", "back", "left", "right", "vertical", "horizontal", "inner", "outer" and the like are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as limiting the present application.
