Description

Technical Field

[0001] This utility model relates to the field of packaging film quality inspection technology, and in particular to a continuous bidirectional packaging film quality inspection device. Background Technology

[0002] The continuous bidirectional packaging film quality inspection equipment is a highly automated optical inspection system designed for uninterrupted, real-time, bidirectional (i.e., both width and length directions of the film roll) quality inspection on packaging film production lines. It integrates advanced machine vision, spectral analysis, and motion control technologies, enabling high-speed online detection of various defects on the film surface and internal structures. It also provides automatic marking, classification, statistics, and reporting, ensuring consistent quality across all film rolls leaving the factory.

[0003] Existing continuous two-way packaging film quality inspection equipment is installed in industrial production lines. Its high-speed camera is interfered with by mechanical vibrations generated by motors, rollers, etc., which causes relative movement between the camera and the film at the moment of exposure, resulting in blurred images. This seriously affects the accuracy of identifying and detecting minor defects. Utility Model Content

[0004] Therefore, it is necessary to provide a continuous two-way packaging film quality inspection device to address the problem that mechanical vibration in industrial environments causes camera imaging to become blurred, which seriously affects the accuracy of defect detection.

[0005] A continuous bidirectional packaging film quality inspection device includes: a visual defect detection system, wherein a support bracket is fixedly connected to each of the two opposite ends of the visual defect detection system; The locking mechanism comprises two locking mechanisms, each including a base plate fixedly connected to the bottom of a support bracket. The top of the base plate has an insertion hole and an annular groove. The insertion hole is located inside the annular groove, and a flange bolt is inserted into the inner side of the insertion hole. The shank of the flange bolt extends through the insertion hole, and the head of the flange bolt has a one-way positioning groove. A frame is inserted into the annular groove, and a one-way positioning block is fixedly connected to the top of the frame, which engages with the one-way positioning groove. The one-way positioning block blocks the one-way positioning groove in the same direction as the flange bolt shank exiting the insertion hole.

[0006] In one embodiment, the number of unidirectional positioning slots and unidirectional positioning blocks is no less than twenty, and the unidirectional positioning slots and unidirectional positioning blocks are all distributed in a ring around the insertion hole.

[0007] In one embodiment, the vertical cross-sectional shapes of the unidirectional positioning groove and the unidirectional positioning block are matching right-angled triangles.

[0008] In one embodiment, the vertical and inclined surfaces of two adjacent unidirectional positioning slots are adjacent, and the vertical and inclined surfaces of two adjacent unidirectional positioning blocks are adjacent.

[0009] In one embodiment, the horizontal cross-sectional shape of both the annular groove and the insert frame is a frame shape with an inner circle and an outer square.

[0010] In one embodiment, a first rubber pad is adhered to the bottom of the insert frame, and the bottom of the first rubber pad contacts the annular groove.

[0011] In one embodiment, the first rubber pad is always in a compressed state, and the first rubber pad is a fluororubber material component.

[0012] In one embodiment, the locking mechanism further includes a second rubber pad adhered to the bottom of the base plate, the top of the second rubber pad having a through hole communicating with the insertion hole, and the shank of the flange bolt passing through the through hole.

[0013] Beneficial effects 1. In the above-mentioned continuous bidirectional packaging film quality inspection equipment, the locking mechanism is inserted into the insertion hole of the base plate by the flange bolt, and the one-way positioning block of the insertion frame is inserted into the one-way positioning groove of the flange bolt head. Since the blocking direction of the one-way positioning block is the same as the withdrawal direction of the flange bolt rod, a mechanical self-locking is formed, which effectively prevents the bolt from loosening due to vibration and ensures the stable installation of the visual defect detection system.

[0014] 2. The first and second rubber pads of the locking mechanism provide elastic damping under compression to attenuate high-frequency and low-frequency vibrations. At the same time, the right-angled triangular cross-section of the unidirectional positioning block and the unidirectional positioning groove cooperate to form a reverse mechanical block to prevent the flange bolts from loosening. The dual mechanism reduces relative movement and ensures the stability of the image acquisition unit at the moment of exposure. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The following is combined with Figure 1 - Figure 5 This invention describes a continuous bidirectional packaging film quality inspection device.

[0020] In one embodiment, a continuous bidirectional packaging film quality inspection device includes: a visual defect detection system 100 and two locking mechanisms 300, wherein a support bracket 200 is fixedly connected to each of the two opposite ends of the visual defect detection system 100.

[0021] The visual defect detection system 100 mainly consists of four parts: an image acquisition unit, a dedicated lighting system, an image processing and analysis unit, and an execution auxiliary unit. The image acquisition unit typically uses a high-resolution line scan camera, such as the KT-STAFIC8000 8K intelligent camera from Kuntian Automation, paired with a specific optical lens. The lighting system uses high-brightness LED line light sources or backlights to ensure stable and clear imaging. The processing unit relies on an industrial computer equipped with a high-speed image acquisition card from the CRECO brand and deep learning algorithm software for analysis. The execution unit includes an audible and visual alarm. All these components are precisely integrated into the mechanical frame and sealed protective housing of the rewinding machine.

[0022] The working principle of the visual defect detection system 100 is a closed-loop "perception-analysis-execution" process: the film moves at a constant speed driven by the rewinder, the encoder triggers the line scan camera to synchronously acquire images line by line, and the illumination system highlights the contrast of defects; the acquired high-speed image data is processed, identified and classified in real time by software algorithms; once a defect is confirmed, the system immediately records all defect information and drives the audible and visual alarm, and can also upload the data to the remote management platform according to needs and preset programs.

[0023] The quality inspection process of the visual defect detection system 100 is as follows: The film is drawn out from the unwinding roller, stabilized by the guide roller and the correction device, and then enters the inspection area. The vision system performs online real-time detection and defect marking. After the film rolls have been inspected and marked, they are either put into storage as finished products with attached quality reports or enter the slitting process to automatically remove defective products using defect location information. Finally, the quality reports generated by the system provide data support for process optimization and production management, thereby achieving efficient quality control and continuous improvement.

[0024] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the locking mechanism 300 includes a base plate 310 fixedly connected to the bottom of the support bracket 200. The top of the base plate 310 has an insertion hole 311 and an annular groove 312. The insertion hole 311 is located inside the annular groove 312. A flange bolt 320 is inserted into the inner side of the insertion hole 311, with the shank of the flange bolt 320 extending through the insertion hole 311. A one-way positioning groove 321 is formed at the head of the flange bolt 320. A frame 330 is inserted into the annular groove 312. A one-way positioning block 340, which engages with the one-way positioning groove 321, is fixedly connected to the top of the frame 330. The direction in which the one-way positioning block 340 blocks the one-way positioning groove 321 is the same as the direction in which the shank of the flange bolt 320 exits the insertion hole 311. The number of one-way positioning grooves 321 and one-way positioning blocks 340 is not less than twenty, and the number of one-way positioning grooves 321 and one-way positioning blocks 340 is also not less than twenty. All are arranged in a ring around the insertion hole 311; the vertical cross-sectional shape of the one-way positioning groove 321 and the one-way positioning block 340 is a matching right triangle; the vertical and inclined surfaces of two adjacent one-way positioning grooves 321 are adjacent, and the vertical and inclined surfaces of two adjacent one-way positioning blocks 340 are adjacent; the horizontal cross-sectional shape of the ring groove 312 and the insertion frame 330 is a frame shape with an inner circle and an outer square; a first rubber pad 350 is bonded to the bottom of the insertion frame 330, and the bottom of the first rubber pad 350 is in contact with the ring groove 312; the first rubber pad 350 is always in a compressed state, and the first rubber pad 350 is a fluororubber material component; the locking mechanism 300 also includes a second rubber pad 360 bonded to the bottom of the base plate 310, and the top of the second rubber pad 360 has a through hole 361 communicating with the insertion hole 311, through which the shank of the flange bolt 320 passes.

[0025] Working principle: The visual defect detection system 100 is fixedly connected to the base plate 310 of the locking mechanism 300 through the bearing brackets 200 on its two opposite sides, thus being installed on the top of the rewinding machine. The specific anchoring process is as follows: First, the insert frame 330 along with the first rubber pad 350 is embedded into the annular groove 312. Then, the shank of the flange bolt 320 passes through the insertion hole 311 of the base plate 310 and the through hole 361 of the second rubber pad 360 in sequence and is screwed into the threaded hole on the top of the rewinding machine. During this process, the one-way positioning block 340 on the top of the insert frame 330 is precisely inserted into the one-way positioning groove 321 on the head of the flange bolt 320. The annular groove 312 and the inner circle and outer square frame cross section of the insert frame 330 prevent rotation, forming a mechanical directional self-locking mechanism.

[0026] This structure addresses the imaging blurring caused by vibration through a dual mechanism: First, the elastic compression of the first rubber pad 350 and the second rubber pad 360 effectively attenuates the high-frequency vibration and low-frequency resonance transmitted by the rewinding machine; second, the right-angled triangular cross-sections of the unidirectional positioning block 340 and the unidirectional positioning groove 321 form a reverse mechanical barrier, preventing the flange bolts 320 from loosening during vibration, ensuring that the image acquisition unit of the visual defect detection system 100 maintains zero relative displacement with the film at the moment of exposure, thereby ensuring the stable operation of the illumination system and the image processing and analysis unit, and ultimately achieving high-precision defect identification and marking.

[0027] It should be noted that the visual defect detection system 100 and the rewinder mentioned above are both devices with relatively mature existing technologies. The specific models can be selected according to actual needs. At the same time, both the visual defect detection system 100 and the rewinder are powered by mains power. The specific power supply method can be selected according to the situation, which will not be elaborated here.

[0028] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
