Description

Technical Field

[0001] This utility model relates to the field of cigarette box detection technology, and in particular to a novel aluminum paper five-wheel imaging detection system. Background Technology

[0002] To reduce costs and make raw materials more environmentally friendly, the cigarette factory introduced a new type of aluminum foil as the inner lining of small cigarette packs. This aluminum foil has two characteristics: First, the upper 1 / 3 of it is made of the new aluminum foil with extremely low metal content, about 1 / 200 of the original aluminum foil, and its resistance is infinite when measured with a multimeter in ohm mode; Second, the remaining 2 / 3 is white paper that does not contain any metal.

[0003] The original design of the existing ZB416 packaging machine was to use white light to photograph the inside of the cigarette pack in a single pass. Due to the unique nature of the inspection location, it was greatly affected by light and mechanical packaging, and the inner lining paper used was a new type of aluminum foil. As a result, too many defective aluminum foil cigarette packs were mistakenly rejected during the operation of the equipment, which seriously affected the normal quality of the product. This led to defective aluminum foil cigarette packs entering the market, affecting the product quality and reputation of enterprises. Therefore, the inspection of the new type of aluminum foil in the packaging machine has become an urgent problem.

[0004] Therefore, providing a detection system that can accurately detect novel aluminum paper is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0032] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] like Figure 1 As shown, this utility model embodiment provides a novel aluminum paper five-wheel imaging detection system, including: an industrial control computer 1, an IO control board 2, a CCD detection camera 3, and a laser 4;

[0034] The IO control board 2 is connected to the industrial computer 1, the CCD inspection camera 3 and the laser 4 respectively;

[0035] The industrial control computer 1 is connected to the CCD detection camera 3;

[0036] Both the CCD detection camera 3 and the laser 4 are arranged perpendicularly to the cigarette pack conveyor belt.

[0037] The IO control board 2 is used to control the operation of the industrial computer 1, the CCD inspection camera 3 and the laser 4;

[0038] The CCD detection camera 3 is used to acquire images of the cardboard and aluminum foil inside the cigarette pack.

[0039] The laser 4 is used to illuminate the small cigarette pack.

[0040] In practical applications, both the CCD inspection camera and the laser are positioned perpendicular to the cigarette pack conveyor belt. The IO control board sends a trigger signal to the CCD inspection camera to capture images of the cardboard and aluminum foil inside the cigarette packs. Simultaneously, it controls the laser to flash, providing illumination for the CCD inspection camera. The CCD inspection camera then sends the captured images to the industrial control computer. The industrial control computer processes the images according to image processing requirements and finally sends an image quality signal to the IO control board. Through the coordinated operation of the industrial control computer, CCD inspection camera, and laser, defective aluminum foil can be accurately detected, improving product quality. Furthermore, this system is versatile and suitable for any type of packaging machine.

[0041] Preferably, the laser 4 is a grid laser;

[0042] The grid laser 4 is connected to the IO control board 2.

[0043] In practical applications, a grid laser is added to the existing lighting system. The grid laser offers grid laser imaging capabilities; for example... Figure 2 As shown, grid laser imaging can improve many problems caused by the reflection of aluminum foil materials; at the same time, it adds laser line projection characteristics to the grid laser, such as... Figure 3 As shown in (a), the feedback light information no longer simply describes the characteristics of the measured object as grayscale spots, but forms a highly informative feedback of the measured object's characteristics, such as... Figure 3 As shown in (b), by setting up a laser, various defects such as missing, skewed, open, wrinkled, and dented inner aluminum lining paper can be effectively detected, thereby achieving high-precision detection.

[0044] Preferably, the CCD inspection camera 3 includes: a three-wheel inspection camera 31 and a five-wheel inspection camera 32;

[0045] The IO control board 2 is connected to the three-wheeled detection camera 31 and the five-wheeled detection camera 32 respectively.

[0046] In practical applications, the CCD inspection cameras used include three-wheel inspection cameras and five-wheel inspection cameras. The flatness of the aluminum foil surface is detected by the three-wheel inspection camera and the grid laser. The flatness of the surface of some aluminum foil and inner cardboard is detected by the five-wheel inspection camera and the grid laser. The difference between the three-wheel inspection camera and the five-wheel inspection camera in this embodiment is that the three-wheel inspection camera only detects aluminum foil, while the five-wheel inspection camera detects both aluminum foil and inner cardboard.

[0047] Preferably, it further includes: encoder 5;

[0048] The encoder 5 is connected to the IO control board 2;

[0049] The encoder 5 is used to ensure that the electrical zero position of the equipment is consistent with the mechanical zero position of the equipment, so as to obtain a signal that the cigarette box is in place.

[0050] In practical applications, an encoder is used to ensure that the electrical zero position of the equipment is consistent with the mechanical zero position of the equipment, thereby facilitating the receipt of a signal indicating that the cigarette pack has been properly positioned. The encoder then sends this signal to the IO control board, which controls other components based on the signal. In this embodiment, the signal error is controlled within the allowable range of the PLC program settings.

[0051] Preferably, it further includes: a rejection machine 6;

[0052] The rejection machine 6 is connected to the IO control board 2;

[0053] The rejection machine 6 is used to receive signals sent by the IO control board 2 and reject unqualified cigarette packs.

[0054] In practical applications, a rejection machine is also installed, and the rejection machine is connected to the IO control board. When the IO control board receives the image good / bad signal sent by the industrial control computer, the IO control board controls the rejection machine to reject the unqualified cigarette packs according to the bad image signal.

[0055] Preferably, it also includes: an alarm 7;

[0056] The alarm 7 is connected to the IO control board 2;

[0057] The alarm 7 is used to receive signals sent by the IO control board 2 and trigger an alarm.

[0058] In practical application, an alarm is also installed. While the IO control board controls the rejection machine to reject non-compliant cigarette packs based on the bad image signal, it also controls the alarm to sound.
