Description

Technical Field

[0001] The invention relates to the technical field of optical testing and identification, in particular to a plastic film quality detection device. Background Art

[0002] During the production and processing of plastic film, it is necessary to detect and process whether there are stains on the surface. By detecting stains on the surface of plastic film, unqualified products can be found and removed in time to ensure the quality of the final product. It can also improve the flatness and cleanliness of the surface of the plastic film. Therefore, plastic film surface stain detection plays a significant role in improving product quality, reducing losses and improving production efficiency, and is an indispensable part of modern industrial production.

[0003] In the prior art, the detection equipment used for plastic film quality uses visual recognition technology based on visible light to detect stains on the surface of plastic films. However, when unclear or stains are found, they can only be processed manually, resulting in low detection efficiency and frequent interruptions of the detection process. When an automated cleaning roller is used to clean the identified stains, the plastic film body will vibrate significantly due to the change in applied pressure, thereby causing local deformation. Summary of the invention

After the present invention detects the presence of stains on the surface of the plastic film through visual recognition, the approximate position of the stain on the plastic film can be judged, and the subsequent inspection and removal components can be accurately controlled to remove the stain in a targeted manner. During the removal process, the plastic film around the stain is always supported. Therefore, while providing a higher-intensity erasing effect, the vibration amplitude of the plastic film in the erasing area is also effectively reduced, thereby reducing the impact on the plastic film body and reducing the probability of deformation.

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0020] See also Figures 1 to 7The present invention provides the following technical solutions: a plastic film quality inspection device, comprising an inspection device body, the inspection device body comprising a bottom plate 1, a fill light platform 3, a lifting mechanism 5 and an inspection and removal component 6, the surface of the bottom plate 1 is screwed with the fill light platform 3, the side of the bottom plate 1 is welded with a side plate 36, the top of the side plate 36 is welded with a top plate 2, one end of the top plate 2 is integrally formed with an extension plate 7, the bottom of the extension plate 7 is plugged with a visual camera 8, and the visual camera 8 is aligned with the center point of the bottom fill light platform 3, one end of the surface of the fill light platform 3 is welded with a guide roller 30, the top of the lifting mechanism 5 is installed with an electric lifting rod 12, and the lifting mechanism 5 is fixed below the top plate 2, the surface of the bottom plate 1 is welded with a vertical plate 9, the inner side of the vertical plate 9 is installed with a middle-layer support component 16, the surface of the middle-layer support component 16 is sleeved with an edge support component 17, and the middle-layer support component 16 and the edge support component 17 are both installed in the middle position of the lifting mechanism 5, and one end of the surface of the bottom plate 1 is screwed with a winding guide roller 4. The plastic film quality inspection device is used to inspect whether there are stains such as dust and impurities on the surface of the plastic film.

[0021] When the present invention is used, the plastic film to be tested is passed around the top of the guide roller 30 and then passed through the inside of the lifting mechanism 5, and then passed through the inside of the detection and removal component 6, and finally rolled up with the help of the winding guide roller 4 at the end. In this process, the plastic film to be tested will be laid on the surface of the light-filling platform 3, and the light-filling platform 3 will be used to illuminate and fill light from the bottom, and the surface of the plastic film to be tested will be photographed and identified from the top with the help of the visual camera 8, and the image will be processed by the image analysis software to find defects and calculate and analyze them to determine the size, position and type of the defects. After the stain is detected in this process, the position of the stain on the surface of the plastic film to be tested is determined, and then the detection and removal component 6 at the rear end can be controlled to start two motors and the lifting mechanism 5 respectively to pull up or press down the area where the stain appears on the plastic film to be tested, and the sponge brush is used to clean and remove the stain part. Among them, the visual camera 8 belongs to the existing mature technology, and the scanning system used to detect and identify the stain and the subsequent matching image analysis software processing software do not belong to the protection scope of the present invention, so its operating principle and recognition scanning process are not described here.

[0022] In this embodiment, the detection and removal component 6 includes a middle-layer support component 16 and an edge support component 17. The top of the vertical plate 9 is welded with a front-end plate 10, the inner side of the side plate 36 is welded with a rear-end plate 24, and the outer side of the vertical plate 9 is screwed with a first motor 18. The front-end plate 10 and the rear-end plate 24 are on the same vertical plane, and the front-end plate 10 and the rear end are both vertical to the surface of the bottom plate 1 and the top plate 2. Both ends of the middle-layer support component 16 and the edge support component 17 are inserted into the interior of the front-end plate 10 or the rear-end plate 24. After the presence of stains on the surface of the plastic film is detected by visual recognition, the approximate position of the stain on the plastic film can be judged, and the subsequent detection and removal component 6 can be precisely controlled to remove the stain in a targeted manner. The entire process does not require manual intervention, which reduces the intensity of manual labor and improves the efficiency of detection and recognition.

[0023] Specifically, after the visual camera 8 detects and identifies the stain, if it is found that the stain is near the middle of the plastic film to be tested, the middle support assembly is controlled to rotate continuously, and the edge support assembly 17 controls the second cam 34 on the surface to point to the middle area and then stops running. In this state, the lifting mechanism 5 is controlled to rise and move down in sequence. After the surface of the plastic film to be tested contacts the surface of the second cam 34, the stain in the middle area can be wiped off and cleaned by continuous rotation of the middle support assembly 16. If the visual camera 8 recognizes that the stain is near the edge, the edge support assembly 17 is used for erasing, while the middle support assembly 16 remains fixed to provide support.

[0024] In this embodiment, the middle-layer support assembly 16 includes a bottom-layer drive shaft 19, a first sponge brush 20 and a first cam 21. One end of the bottom-layer drive shaft 19 is inserted into the output end of the first motor 18. A driven shaft 37 is also inserted between the front end plate 10 and the rear end plate 24. The surfaces of the driven shaft 37 and the bottom-layer drive shaft 19 are both sleeved with the first sponge brush 20. The surface of the first sponge brush 20 is embedded with the first cam 21. The surfaces of the driven shaft 37 and the bottom-layer drive shaft 19 are key-connected with a first transmission gear set 22, and the surface of the first transmission gear set 22 is sleeved with a first toothed belt 23. In the process of removing the detected stains, a support effect will always be provided to the plastic film around the stains. Therefore, while providing a high-strength erasing effect, the vibration amplitude of the plastic film in the erasing area is also effectively reduced, thereby reducing the impact on the plastic film body and reducing the probability of deformation.

[0025] In this embodiment, the edge support assembly 17 includes a top driving shaft 26 and an outer sleeve 28. The surface of the rear end plate 24 is screwed with a second motor 25. The top driving shaft 26 is inserted into the output end of the second motor 25. The surface of the top driving shaft 26 is keyed to a second transmission gear set 27. The surface of the second transmission gear set 27 is sleeved with a second toothed belt 31. One end of the outer sleeve 28 is sleeved with a second sponge brush 35. The surface of the second sponge brush 35 is embedded with a second cam 34. The surface of the outer sleeve 28 is keyed to the second transmission gear set 27. The surface of the third transmission gear set 29 is sleeved with a third toothed belt 32. The inner wall of the outer sleeve 28 is embedded with a docking bearing 33. The docking bearing 33 is sleeved on the surface of the bottom driving shaft 19 or the driven shaft 37. There are four outer sleeves 28. The bottom driving shaft 19 and the driven shaft 37 both pass through the middle of the two outer sleeves 28 and the second sponge brush 35.

[0026] Specifically, after the stain is detected and identified by the visual camera 8, if it is found that the stain is near the middle of the plastic film to be tested, the second motor 25 is started at this time, and the top driving shaft 26 is rotated, and each outer sleeve 28 is pulled to rotate synchronously with the second transmission gear set 27, so that the second sponge brush 35 connected to one end of each outer sleeve 28 and the second cam 34 on the second sponge brush 35 are rotated to point to the direction of the plastic film. In this state, whether the lifting mechanism 5 is controlled to rise or move downward, the surface of the plastic film will be pressed against the fixed second cam 34, and the lifting mechanism 5 is continuously started at this time. The first motor 18 can drive the bottom driving shaft 19 to rotate through the first motor 18, and then the bottom driving shaft 19 drives the driven shaft 37 to rotate with the help of the first transmission gear set 22. Therefore, the first sponge brush 20 on the bottom driving shaft 19 and the driven shaft 37 can erase the stains on the plastic film through its own continuous rotation. The visual camera 8 recognizes that the stain is close to the edge, and in turn uses the edge support component 17 for erasing, while the middle-layer support component 16 remains fixed to provide support. The whole process can ensure that there is a support area around the stain to provide a stable support effect.

[0027] In this embodiment, the lifting mechanism 5 includes a lifting plate 11 and a traction rod 14. The bottom of the electric lifting rod 12 is screwed to the surface of the lifting plate 11. The bottom end of the lifting plate 11 is welded with a lifting frame 13. The two ends of the traction rod 14 are embedded in the inner wall of the lifting frame 13 through bearings. A gap 15 is set between the two traction rods 14 on the same vertical line. The plastic film to be tested passes through the inside of the gap 15, and the traction rod 14 is used to pull up or press down the plastic film to be tested. The middle support component 16 and the edge support component 17 are respectively used to remove the stains identified in different areas of the plastic film surface, and the lifting mechanism 5 at both ends can directly support the stain area, so that the impurities such as adhered dust can be in a concave state, so that the wiping pressure can be controlled, and the sponge brush in the wiping process can contact with a larger area of ​​the plastic film surface, expanding the scope of single wiping, and avoiding the phenomenon that the plastic film in the area is broken due to excessive concentration of the wiping area.

[0028] Specifically, after starting the electric lifting rod 12, the inner traction rod 14 can be pulled upward or downward with the help of the lifting plate 11 and the lifting frame 13, and then the plastic film can be pulled up or pressed down on both sides of the detection and cleaning component 6, so that the stain area can be pressed within the range of the detection and cleaning component 6, so as to facilitate the above-mentioned targeted cleaning treatment of the stain area. In addition, during the normal detection process, when the visual camera 8 does not identify the stain problem, the plastic film at this time directly passes through the inside of the gap 15 and will not contact any surface of the traction rod 14.

[0029] The basic principles and main features of the present invention and the advantages of the present invention are shown and described above. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
