Description

Technical Field

[0001] The invention relates to the technical field of cloth optical detection, in particular to a detection device for double-sided printed cloth. Background Art

[0002] The production and processing of double-sided printed fabrics requires multiple processing steps. After the printing process is completed, in order to evaluate the quality of the fabric, the structural integrity of the fabric surface and the color difference and texture of the printed pattern will be analyzed and studied based on the purpose of the fabric, so as to determine the value of the fabric and identify whether it meets the specified standards. This process requires the use of corresponding fabric testing equipment.

[0003] In the prior art, an industrial camera is usually used to directly capture images of the surface of double-sided printed fabrics to determine whether there are defects in the printed pattern. Then, a visual recognition system can be used to determine whether the fabric in the captured image has the above-mentioned problems. However, this solution cannot accurately detect minor defects or loose yarns. At the same time, once impurities and dust adhere to the surface of the fabric, it is easy to interfere with the subsequent recognition process, so that some qualified fabrics will still not pass smoothly due to the adhered impurities. The use of conventional dust removal equipment will increase the cost and energy consumption of the entire process. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a detection device for double-sided printed fabrics to solve the problems raised in the above-mentioned background technology. The present invention allows the fabric to be tested to pass through the interior of the detection box, and uses the internally arranged photosensitive chamber and lighting chamber to detect whether there are defects, damages, loose yarns and other problems on the surface of the fabric. The detection efficiency is higher and external light interference is avoided. At the same time, it can automatically achieve the effect of cleaning and dust removal on both sides of the internal fabric, thereby improving the accuracy of subsequent recognition of the pattern on the fabric surface.

DETAILED DESCRIPTION

[0026] 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.

[0027] See also Figures 1 to 6 The present invention provides the following technical solutions: a detection device for double-sided printed fabrics, comprising a detection device body, the detection device body comprising a bottom detection box 5, a top detection box 6, a blocking mechanism 10 and a dust removal mechanism 11, a bottom plate 1 is installed at the bottom of the bottom detection box 5, a bracket 2 is fixedly installed on the surface of the bottom plate 1, and two brackets 2 are provided, a feed guide roller 3 and a discharge guide roller 4 are respectively installed at the top of the two brackets 2, a fixing plate 7 is installed in the middle of each bracket 2, the side of the top detection box 6 is installed on the fixing plate 7 with screws, the blocking mechanism 10 and the dust removal mechanism 11 are both installed in the cavity inside the bottom detection box 5 and the top detection box 6, a top rod 20 is provided on the surface of the dust removal mechanism 11, the double-sided printed fabric to be tested passes through the inside of the bottom detection box 5 and the top detection box 6, and the surface of the top rod 20 is against the surface of the double-sided printed fabric, and an industrial camera 8 is installed at one end of the surface of the top detection box 6.

[0028] The double-sided printed fabric detection device is used to detect whether there are defects, damage, loose defense lines, and errors in printed patterns on the surface of high-density double-sided printed fabrics. During the detection, the double-sided printed fabric to be tested is directly bypassed from the feed guide roller 3 at the top of one end, and then passed through the outer extrusion interlayer 30 between the bottom detection box 5 and the top detection box 6. Inside the detection box, the defects, damage, and loose defense lines on the surface of the double-sided printed fabric to be tested are detected and processed through the light source 15 and the photosensitive sensor 16 elements. At the same time, the two sides of the fabric are provided with a beating dust removal and cleaning treatment in the dust removal chambers 12 at both ends of the detection box. Finally, when passing through the inside of the detection box, the image can be captured by the industrial camera 8 on the top, and then the purpose of detecting the printed pattern is achieved with the help of the visual recognition system. Among them, the light source 15, the photosensitive sensor 16, the industrial camera 8 and the matching visual recognition system are all existing mature technologies. This part of the structure is only used to solve the functional requirements required by the present invention and does not belong to the protection scope of the present invention. Therefore, its specific structure and principle are not described here.

[0029] In this embodiment, the bottom detection box 5 and the top detection box 6 are provided with a dust removal chamber 12, a photosensitive chamber 14 and an illumination chamber 13. An outer extrusion interlayer 30 is provided between the bottom detection box 5 and the top detection box 6, and the edge of the double-sided printed fabric is embedded in the outer extrusion interlayer 30. Scrapers 17 are provided at both ends of the outer extrusion interlayer 30. Four dust removal chambers 12 are provided, and one photosensitive chamber 14 and one illumination chamber 13 are provided. The dust removal chamber 12 is symmetrically installed on both sides of the barrier mechanism 10, and the photosensitive chamber 14 and the illumination chamber 13 are surrounded by the barrier mechanism 10.

[0030] A light source 15 is installed on the top of the lighting chamber 13, a support plate 18 is installed at the middle bottom of the photosensitive chamber 14, a photosensitive sensor 16 is installed on the surface of the support plate 18, a photosensitive resistor element is installed inside the photosensitive sensor 16, an air pump 9 is installed on one end of the surface of the bottom plate 1, the output end of the air pump 9 is connected to a collecting pipe 29, and the surface of the collecting pipe 29 is connected to a plurality of shunt pipes 32, and a dust removal hole 28 is opened on the side of each dust removal chamber 12, and the end of each collecting pipe 29 is connected to the inside of the dust removal chamber 12 through the dust removal hole 28. By passing the fabric to be tested through the inside of the detection box, and installing the photosensitive sensor 16 and the light source 15 equipment in the photosensitive chamber 14 and the lighting chamber 13 respectively, it is possible to detect whether there are problems such as defects, damages and loose yarns on the surface of the fabric, the detection efficiency is higher, and the blocking mechanism 10 can effectively avoid external light interference.

[0031] Specifically, when the double-sided printed fabric passes through the interior of the detection box, the top lighting chamber 13 and the bottom photosensitive chamber 14 will be separated. At this time, the light beam generated by the light source 15 at the top of the lighting chamber 13 will be directly blocked by the double-sided printed fabric. At this time, the light intensity inside the photosensitive chamber 14 is always in an extremely low state and remains stable. When the surface of the double-sided printed fabric is defective, damaged or the defense line is loose, the light inside the lighting chamber 13 will pass through the abnormal double-sided printed fabric surface and enter the bottom photosensitive chamber 14, thereby affecting the photosensor 16 and generating a change in the electrical signal. It can be determined that the part of the double-sided printed fabric that has passed at this time has the above-mentioned abnormal problems of defect, damage, and loose defense line.

[0032] In this embodiment, the blocking mechanism 10 includes a bottom partition 22, a top partition 23 and a clamping plate 26. The ends of the bottom partition 22 and the top partition 23 that are away from each other are respectively welded to the inner walls of the bottom detection box 5 and the top detection box 6 as a whole, and the ends of the bottom partition 22 and the top partition 23 that are close to each other are installed with a clamping plate 26. Arc plates 24 are arranged on both sides of the clamping plate 26. An inner extrusion interlayer 25 is arranged between two adjacent clamping plates 26, and rubber pads are attached to the surfaces of the clamping plate 26 and the arc plate 24. The double-sided printed fabric to be tested passes through the inside of the two inner extrusion interlayers 25 in turn, and the photosensitive chamber 14 and the lighting chamber 13 are blocked by the double-sided printed fabric.

[0033] When the double-sided printed fabric passes through the interior of the inspection box, the side of the double-sided printed fabric is squeezed and enclosed by the outer extrusion interlayer 30, and the part of the double-sided printed fabric inside the inspection box is clamped and enclosed by the inner extrusion interlayer 25. Therefore, the blocking mechanism 10 and the bottom inspection box 5 and the top inspection box 6 can ensure that the lighting chamber 13 and the photosensitive chamber 14 are both in a closed state. Combined with the filling effect of the double-sided printed fabric itself on the gap, the external light and the light of the light source 15 in the lighting chamber 13 cannot directly pass through the surface of the qualified double-sided printed fabric.

[0034] In this embodiment, the dust removal mechanism 11 includes a drive shaft 19, a gear 34 and a transmission belt 21. The sides of the bottom detection box 5 and the top detection box 6 are provided with strip holes 31. The gears 34 are installed at both ends of the drive shaft 19. The transmission belt 21 is sleeved on the surface of the gear 34. The surface of the drive shaft 19 is connected with a transmission rod 33. Both ends of each top rod 20 are movably connected with the side of the transmission rod 33. Support bearings 27 are embedded on the inner wall of the bottom detection box 5 and the top detection box 6. Both ends of the drive shaft 19 pass through the inside of the support bearing 27. Each gear 34 is hidden inside the bottom detection box 5 and the top detection box 6. The surface of the transmission belt 21 passes upward from the top of the strip hole 31. Two dust removal chambers 12 are separated at both ends by the blocking mechanism 10 and the detection box, and the cleaning and dust removal effect of the internal moving over both sides of the cloth is achieved with the help of the dust removal mechanism 11, so as to prevent impurities adhering to the surface of the cloth from interfering with the subsequent image recognition process. The accuracy of subsequent recognition of the surface pattern of the fabric is improved. In this process, after the fabric to be tested passes through the inner part of the outer extrusion interlayer 30, the inner dust removal mechanism 11 can be automatically driven to rotate by the extrusion effect, so there is no need to build additional power equipment, which reduces the equipment cost.

[0035] Specifically, when the double-sided printed fabric passes through the inside of the external extrusion clamp, an extrusion effect is generated on the surface of the transmission belt 21. Therefore, as the double-sided printed fabric moves, the transmission belt 21 is directly driven to rotate. The transmission belt 21 drives the inner gear 34 to rotate, which can control the rotation of the drive shaft 19 in the gear 34. During the rotation of the drive shaft 19, the side transmission rod 33 and the push rod 20 are directly rotated, so that the push rod 20 is against the two sides of the double-sided printed fabric. By frequently beating the surface of the double-sided printed fabric with the push rod 20, the impurities and dust adhering to the double-sided printed fabric can be shaken off. At this time, the external air pump 9 extracts the impurities and dust that fall from the dust removal cavity due to the beating by exhausting air, so as to avoid a large amount of impurities and dust adhering to the surface of the double-sided printed fabric for a long time. Therefore, when the part of the double-sided printed fabric that passes through the inside of the detection box is subsequently moved to the front of the industrial camera 8 for image acquisition, the interference of the impurities and dust adhering to the surface on the accuracy of visual recognition can be reduced.

[0036] 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.

[0037] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
