Technical Field

[0001] This utility model relates to the field of cigarette equipment technology, and in particular to a small pack transparent paper detection device. Background Technology

[0002] The top and bottom surfaces of cigarette packaging transparent paper (such as BOPP film) are easily affected by mechanical extrusion or heat sealing processes during packaging, resulting in defects such as bubbles and creases. These defects directly affect the product's sealing performance and appearance quality, and need to be tested to ensure product quality. Currently, this is generally done through manual visual inspection, which has low testing efficiency.

[0003] Existing technology CN208377222U discloses a device for detecting defects in the transparent paper of cigarette packs, including a mounting bracket, a through-beam fiber optic sensor, a fiber optic signal amplification circuit, and a central processing unit (CPU). The through-beam fiber optic sensor includes a transmitter and a receiver, which are located on opposite sides of the pack on a guide rail. The transmitter's emitter is directly opposite the receiver's receiver. The distance between the detection light beam from the transmitter and receiver and the upper surface of the pack is greater than 0 mm and less than or equal to 1 mm. The transmitter and receiver are fixed on the mounting bracket. The first output terminal of the CPU is connected to the control input terminal of the through-beam fiber optic sensor, and the signal output terminal of the through-beam fiber optic sensor is connected to the input terminal of the CPU through the fiber optic signal amplification circuit. The CPU is connected to an industrial control computer. This invention can effectively detect defects such as wrinkles and curling of the transparent paper wrapped in the pack.

[0020] This utility model's small-package transparent paper inspection device includes a body 101, a clamping assembly 102, an upper camera 103, a lower camera 104, a fixing plate 105, a support rod 106, an extension plate 107, a tray 108, a laser bracket 109, an upper laser 110, a lower laser 111, a mounting plate 112, an upper mounting base 113, a lower mounting base 114, an upper light source 115, a lower light source 116, a support frame 117, a display 118, a reinforcing rib 119, and a cigarette pack 120. It solves the problem that while existing technologies can detect defects in transparent paper, they cannot simultaneously perform rapid inspection of both the top and bottom surfaces, resulting in low inspection efficiency. It is understood that the aforementioned solution can also be used to improve inspection efficiency and accuracy.

[0021] In this embodiment, both the body 101 and the clamping component 102 are existing technologies. The clamping component 102 can clamp and fix the cigarette pack 120 through a pneumatic clamp. Through the detection component, the problem that although the existing technology can detect defects in the transparent paper, it cannot simultaneously achieve rapid detection on both the top and bottom sides, resulting in low detection efficiency is solved.

[0022] The upper camera 103 and the lower camera 104 are connected to the body 101 via the supporting member. The supporting member is installed inside the body 101 and supports the upper camera 103 and the lower camera 104. The laser bracket 109 is fixedly connected to the body 101 and located inside the body 101. The upper laser 110 is fixedly installed on the laser bracket 109, and the lower laser 111 is fixedly installed on the laser bracket 109. The light source component is installed on the inner wall of the body 101. Both the upper camera 103 and the lower camera 104 are mounted via the supporting member. Within the body 101, the supporting member provides installation conditions for the upper camera 103 and the lower camera 104, allowing the upper camera 103 and the lower camera 104 to respectively photograph the upper and lower sides of the cigarette pack 120. Both the upper camera 103 and the lower camera 104 are 5-megapixel high-speed area array cameras (frame rate ≥ 200fps), equipped with telecentric lenses (field of view 100mm × 100mm). The cameras have built-in polarizing filters to suppress glare on the transparent paper surface and are used for image acquisition of the upper and lower sides of the cigarette pack 120. The laser bracket 109 is vertically installed within the body 101, providing support for the upper camera 103 and the lower camera 104. The upper laser 110 and the lower laser 111 provide installation conditions. Both the upper laser 110 and the lower laser 111 are 532nm green line lasers. The lower laser 111 is located below the upper laser 110. The upper laser 110 and the lower laser are used to project laser light onto the upper and lower surfaces of the cigarette pack 120, respectively. Both the upper laser 110 and the lower laser 111 project light onto the transparent paper surface of the cigarette pack 120 at a 45° incident angle. Scratches and internal bubbles are detected by the deformation of the reflected light spot. The light source component is installed on the body 101 and the upper laser 110 and... On the side opposite to the lower laser 111, the light source component can be deeply integrated with the upper camera 103, the lower camera 104, the upper laser 110, and the lower laser 111, significantly improving the detection device's comprehensive identification capability for complex defects. Through the dual-station structure design of the upper and lower cameras 104 and the upper and lower lasers 111, images of both the upper and lower sides of the cigarette pack 120 can be acquired, enabling rapid detection of both sides of the cigarette pack 120, improving detection efficiency, and solving the problem that although existing technologies can detect defects in transparent paper, they cannot simultaneously achieve rapid detection of both the upper and lower sides, resulting in low detection efficiency.

[0023] Secondly, the fixing plate 105 is fixedly connected to the body 101 and located on the inner wall of the body 101; the support rod 106 is fixedly connected to the fixing plate 105 and located on one side of the fixing plate 105, and the upper camera 103 is mounted on the end of the support rod 106; the extension plate 107 is fixedly connected to the fixing plate 105 and located on the side of the fixing plate 105 away from the support rod 106; the tray 108 is fixedly connected to the extension plate 107 and located at the end of the extension plate 107 away from the fixing plate 105, and the lower camera 104 is mounted on the tray 108; the fixing plate 105 is fixed to the inner wall of the body 101 by bolts; the support rod 106 is vertically mounted on the fixing plate 105 by a fixing seat; and the upper camera 103 is mounted on the support rod by an adjusting bracket. At the top of 106, the adjustment bracket can adjust the installation angle of the upper camera 103. The extension plate 107 is a rectangular plate, connected to the fixing plate 105 by bolts, and set at a 90-degree angle to the support rod 106. The extension plate 107 serves as a mounting bracket, ensuring that the mounting position of the lower camera 104 is not obstructed, allowing the lower camera 104 to better capture images of the lower surface of the cigarette pack 120. The support plate 108 is fixed to the extension plate 107 by bolts and set at a 90-degree angle to the extension plate 107. The lower camera 104 is mounted on the top of the support plate 108 by the adjustment bracket. Through the support components, the installation conditions for the upper camera 103 and the lower camera 104 are provided, allowing the upper camera 103 and the lower camera 104 to capture images of the upper and lower surfaces of the cigarette pack 120, respectively.

[0024] Meanwhile, the mounting plate 112 is fixedly connected to the body 101 and located inside the body 101; the upper mounting base 113 is fixedly connected to the mounting plate 112 and located on the side of the mounting plate 112 away from the body 101; the lower mounting base 114 is fixedly connected to the mounting plate 112 and located on the side of the mounting plate 112 close to the upper mounting base 113; the upper light source 115 is fixedly mounted on the upper mounting base 113; the lower light source 116 is fixedly mounted on the lower mounting base 114. The mounting plate 112 is a long rectangular plate, vertically mounted on the inner wall of the body 101. The mounting plate 112, the support rod 106, and the laser bracket 109 are on the same straight line. The upper mounting base 113 and the lower mounting base 114 are both bolted to the mounting plate. On 112, the lower mounting base 114 is located below the upper mounting base 113. The upper light source 115 and the lower light source 116 are respectively mounted on the upper mounting base 113 and the lower mounting base 114. Both the upper light source 115 and the lower light source 116 are high-brightness white LED surface light sources (color temperature 6000K), which use a diffuser plate for uniform illumination to detect surface stains, creases, and abnormal transparency. The intensity of the upper and lower light sources 116 is adjustable (0-5000 lux) to adapt to the reflective characteristics of different transparent paper materials. Through the coordinated illumination of the upper and lower light sources 116 and the upper and lower lasers 111, the upper and lower cameras 104 can simultaneously capture surface stains, creases, and internal bubbles, scratches, and other defects of the cigarette pack 120. Through the light source components, the comprehensive identification capability of complex defects can be improved.

[0025] In addition, the support frame 117 is fixedly connected to the machine body 101 and located on one side of the machine body 101; the display 118 is fixedly mounted on the support frame 117, and the support frame 117 is fixed to the top of the machine body 101 by bolts. In order to provide installation conditions for the display 118, the display 118 is fixed to the support frame 117 by bolts. The display 118 has a built-in intelligent image processing system. The display 118 can display the collected images of the top and bottom sides of the transparent paper of the cigarette pack 120, the light transmittance analysis data, the laser stripe distortion information, and the defect detection results in real time. Through the display 118, the operator can intuitively monitor the detection process and adjust the production line process in a timely manner according to the defect information fed back in real time, so as to realize dynamic control of the packaging quality of the cigarette pack 120.

[0026] Finally, the reinforcing rib 119 is fixedly connected to the support frame 117 and is located on the side of the support frame 117 away from the display 118. The reinforcing rib 119 is located below the support frame 117. Through the reinforcing rib 119, the structural strength of the support frame 117 can be enhanced and the stability of the display 118 can be improved.

[0027] In this embodiment, the cigarette pack 120 is clamped and fixed by the clamping assembly 102. The upper light source 115 and the lower light source 116 illuminate the upper and lower surfaces of the cigarette pack 120. The upper laser 110 and the lower laser 111 project onto the transparent paper surface of the cigarette pack 120 at a 45° incident angle. The upper camera 103 and the lower camera 104 collect the patterns on the upper and lower surfaces of the cigarette pack 120. The collected image data is transmitted to the intelligent image processing system. The built-in algorithm (a multi-feature fusion algorithm based on convolutional neural network (CNN) to jointly analyze data such as abnormal light transmittance and laser distortion) analyzes and judges whether there are defects such as scratches, bubbles, and creases on the surface of the cigarette pack 120. The results are displayed in real time on the display 118. By employing a dual-station structure design with upper and lower cameras 104 and upper and lower lasers 111, images of both the upper and lower sides of the cigarette pack 120 can be acquired, enabling rapid detection of both sides of the cigarette pack 120. This improves detection efficiency and solves the problem that while existing technologies can detect defects in transparent paper, they cannot simultaneously achieve rapid detection of both the upper and lower sides, resulting in low detection efficiency.
