[0004] Regarding the above-mentioned related technologies, since the metal detector can only detect metal foreign objects, non-metallic foreign objects such as glass fragments, plastic particles and other foreign objects cannot be effectively identified, affecting the recognition effect of the foreign object recognition device. Utility Model Content

[0005] In order to improve the recognition effect of a foreign object recognition device, the present application provides a foreign object recognition device in a bottle after canning.

[0006] The present application provides a device for identifying foreign matter in a bottle after canning, which adopts the following technical solution:

[0007] A device for identifying foreign matter in a bottle after canning, comprising a composite sensor component, a conveyor belt and a rejection component;

[0008] The conveyor belt is arranged along the length direction of the production line;

[0009] The composite sensor assembly includes a high-frequency electromagnetic sensor, an acoustic wave sensor and an optical sensor;

[0011] The rejecting assembly is used to reject beverage bottles containing foreign matter after filling.

[0012] By adopting the above technical solution, the conveyor belt is first driven to move forward smoothly and continuously along the production line. The conveyor belt receives and smoothly transports the filled beverage bottles one by one. With the movement of the conveyor belt, multiple beverage bottles are smoothly transported to the subsequent links of the production line. During the transportation process, the bottled liquid products pass through the detection area of ​​the composite sensor component one by one. When the beverage bottles are transported to the optical path facing each sensor, the high-frequency electromagnetic sensor will emit high-frequency electromagnetic waves and detect the reflected signals. The acoustic wave sensor sends acoustic waves and detects their reflected signals. The optical sensor uses optical imaging technology to obtain the image inside the bottle and identifies possible foreign objects through image processing algorithms. If there is foreign matter in the bottle, the metal object will change the reflection characteristics of the electromagnetic wave, and the signal received by the high-frequency electromagnetic sensor will change. The non-metallic object will change the sound wave and optical imaging, so that the optical sensor and the sound wave sensor receive the change signal and send the signal to the controller, which will sound an alarm and control the rejection component to reject the beverage bottle with foreign matter from the conveyor belt; the foreign matter identification device in the bottle after canning is convenient for comprehensively identifying the metal and non-metallic foreign matter in the bottle through the composite sensor component, and cooperates with the rejection component to accurately reject the beverage bottle containing foreign matter after filling, effectively improving the recognition effect and recognition accuracy of the foreign matter identification device in the bottle after filling.

[0015] Preferably, the conveying speed of the second conveyor belt is greater than that of the first conveyor belt.

[0016] By adopting the above technical solution, since the speed of the second conveyor belt is faster, during the foreign matter identification process, if the bottled liquid product on the first conveyor belt is detected to contain foreign matter, the unqualified product can be quickly removed from the first conveyor belt to the second conveyor belt, thereby achieving effective separation of the unqualified products.

[0017] Preferably, protective plates are provided on the sides of the first conveyor belt and the second conveyor belt away from each other, and the protective plates are distributed along the length direction of the conveyor belt.

[0020] By adopting the above technical solution, the alarm device can immediately send out an alarm signal when any sensor detects foreign matter in the bottle, so that the operator can quickly learn of the abnormal situation, which is convenient for the operator to quickly locate the beverage bottle containing foreign matter and deal with it in time.

[0021] Preferably, it further comprises a rejection component, wherein the rejection component comprises a manipulator, and the manipulator is arranged facing the composite sensor component.

At the same time, the robot arm has a fast operating speed and high precision, and can quickly complete the rejection action, which is conducive to improving the rejection efficiency of the entire production line.

[0023] Preferably, the rejection assembly includes a mounting seat, a cylinder and a push plate;

[0024] The mounting seat is arranged on a side of the first conveyor belt away from the second conveyor belt;

[0025] The piston rod of the cylinder is fixedly connected to the push plate, and the other end is fixedly connected to the mounting seat;

[0026] The mounting seat, the cylinder and the push plate are all arranged opposite to the connecting point between the first conveying plate belt and the second conveying plate belt.

[0027] By adopting the above technical solution, since the piston rod of the cylinder is fixedly connected to the push plate, the rejection action can be accurately controlled by accurately controlling the telescopic action of the cylinder, and unqualified products can be quickly and accurately pushed from the first conveyor belt to the second conveyor belt, and the mechanical rejection method is faster and more stable, which is beneficial to improving the rejection efficiency of the production line; at the same time, the setting of the rejection component has a certain degree of versatility, which is convenient for adjusting the position and parameters of the mounting seat, cylinder and push plate to adapt to bottled liquid products of different sizes and shapes, which is beneficial to improving the adaptability of the device to various production lines.

[0028] Preferably, the push plate is arranged in an arc shape on a side away from the cylinder to match the side wall of the beverage bottle.

[0032] 2. The rejection component is set up. Since the piston rod of the cylinder is fixedly connected to the push plate, the rejection action can be accurately controlled by accurately controlling the telescopic action of the cylinder, so that unqualified products can be quickly and accurately pushed from the first conveyor belt to the second conveyor belt.
