Description

Technical Field

[0001] This invention relates to the field of garment defect detection equipment, and more particularly to a surface defect detection device for cashmere fabric products. Background Technology

[0002] To ensure the quality of clothing when it leaves the factory, garment companies often use optical inspection equipment to inspect the finished garments as a whole and find out the defects. These devices usually use high-resolution optical imaging technology, which uses a uniform light source to illuminate the fabric surface and combines image analysis algorithms to identify defects such as broken yarns, holes, and oil stains. Automated optical inspection systems can quickly scan large areas of fabric, significantly improving inspection efficiency and reducing the missed detection rate, and have become a key link in the quality control of the textile industry.

[0003] Cashmere fabrics are naturally characterized by their fine fibers and fluffy texture. However, minor imperfections (such as snags or uneven textures) can be difficult to detect due to fiber entanglement or the presence of fuzz. To ensure the quality and user experience of high-end garments, some apparel companies targeting the high-end market have extremely high requirements for the accuracy of cashmere product testing. Therefore, they often choose to manually operate a fabric inspection lamp to re-inspect finished garments before they leave the factory. The core principle of the fabric inspection lamp is to use high-intensity visible light transmission technology. Taking a garment as an example, the operator places the garment over two light-transmitting cones. The strong light generated by the visible light generator inside the cones passes through the garment for inspection. To ensure the accuracy of the light inspection and reduce the probability of false positives and false negatives, the inspector needs to continuously pull the garment to eliminate wrinkles, especially in the armpit area, reducing the area of ​​uneven light transmission caused by wrinkles. This reduces the probability of false positives and false negatives. After the light penetrates the fabric, the fiber structure and shadows of imperfections are clearly visible under the strong light, making it easy to directly identify subtle abnormalities (such as hair particles or discolored hairs) with the naked eye, thus compensating for the blind spots of automated equipment.

[0004] However, the above-mentioned shirt lamp equipment still has the following shortcomings: First, after the garment is placed on the two light-transmitting cones, the inspector needs to repeatedly pull the garment to reduce surface wrinkles. This not only significantly increases the processing time for a single garment, but also significantly reduces the efficiency of the inspection process due to continuous manual adjustments. Second, the equipment requires two major steps for inspecting garment products. The main body area needs to be processed first, and then the cuffs need to be adjusted separately for a second inspection after the inspection is completed. This segmented operation mode requires the inspector to frequently adjust the position of the garment, thus reducing the overall efficiency of the inspection process again. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that the existing technology has the disadvantages of low efficiency due to repeated manual wrinkle removal and the need for frequent adjustment of clothing for segmented detection, which reduces efficiency. To this end, we propose a surface defect detection device for cashmere fabric products.

[0006] To achieve the above objectives, this application adopts the following technical solution: a surface defect detection device for cashmere fabric products, comprising a detection device body 1, which is composed of a grounding base, a rotating disk, and a slide rail. The rotating disk is rotatably connected to the upper surface of the grounding base. Two sets of conical light-transmitting covers 11 are limited and installed on the slide rail by a sliding member (with a limit bolt, which is fixed by the bolt pressing against the slide rail). The sliding member is equipped with a rotating member (the rotating member can be adjusted to rotate left and right for the two sets of conical light-transmitting covers 11). Each set of rotating shafts of the device is equipped with a damping bearing to maintain relative stability during detection. Two sets of conical light-transmitting covers are movably installed on the upper surface of the detection device body. The outer walls of the two sets of conical light-transmitting covers are symmetrically provided with inclined first storage grooves. Each set of first storage grooves is equipped with auxiliary components for positioning the garment and smoothing out wrinkles.

[0007] The auxiliary component also includes an inner support airbag that passes through the cuff and provides support for it. The outer wall of the inner support airbag is coaxially fitted with an outer bulging airbag for driving the cuff to bulge. The outer wall of the outer bulging airbag is fixed at equal angles around the axis with multiple sets of first traction airbags for pulling the cuff to eliminate wrinkles. The interior of the inner support airbag is fixed with multiple sets of porous partitions for separating the interior space of the inner support airbag at equal intervals. The interlayer space between the outer bulging airbag and the inner support airbag is fixed with multiple sets of porous spacer rings.

[0008] Each group of porous spacers has multiple sets of pores for gas passage on its surface at equal angles around the center, and the number of pores on the surface of the multiple groups of porous spacers decreases in a stepwise manner from one side to the other.

[0009] The inner support airbag has a connecting air port at the center of the outer wall on the side away from the mounting plate, which is connected to the inner space of the outer bulging airbag. The interlayer space between the outer bulging airbag and the inner support airbag is connected to the inner space of the inner support airbag through the connecting air port to form a whole.

[0010] The distance between two adjacent sets of first traction airbags increases in a stepped manner from one side to the other, and the inner cavity of the first traction airbag is connected to the inner cavity of the outer bulging airbag. A visible light generating device is installed inside the conical light-transmitting cover.

[0011] Preferably, both the inner support airbag and the outer bulging airbag are corrugated in shape, and one end of the inner support airbag and the outer bulging airbag is fixedly connected to a mounting plate, which is fixedly installed inside the first storage groove by bolts.

[0012] Preferably, the spacing between two adjacent sets of porous spacers decreases in a stepped manner from one side to the other. The adjustable spacing of each section is achieved by the stepped decreasing outward bulging air bladder, so that the fixed point of the cuff is continuously stretched (depending on the different stretching spacing), thereby eliminating some wrinkles to a certain extent. Each set of porous spacers has multiple sets of through holes for gas passage at equal angles around the center, and the number of air holes on the surface of the multiple sets of porous spacers decreases in a stepped manner from one side to the other. The inflation rate of different cavities is adjusted by the change in the number of air holes on the surface of the porous spacers, so as to achieve the effect of gradual elongation.

[0013] Preferably, a first one-way valve is installed at the center of the surface of the mounting plate, allowing air to enter the inner support airbag in only one direction, and the output end of the first one-way valve is connected to the internal space of the inner support airbag. A branch pipe assembly is fixed on the outer wall of the mounting plate on the side away from the inner support airbag, and one set of output ends of the branch pipe assembly is connected to the input end of the first one-way valve.

[0014] Preferably, multiple sets of second one-way valves that only discharge air to the external space are fixed around the center on the surface of the mounting plate and in the space between the outer bulging airbag and the inner supporting airbag. The output end of each set of second one-way valves is connected to the output end of the corresponding position on the branch pipe group. The input end of the branch pipe group is connected to the air supply system through a connecting pipe.

[0015] Preferably, the lower side of the outer wall of the conical light-transmitting cover is provided with multiple sets of second storage slots with inclined internal spaces at equal angles around the center, and each set of second storage slots is fixed with a second traction airbag for pulling the hem of the clothing downward.

[0016] Preferably, the internal volume of each group of second traction airbags is larger than the internal volume of the second storage slot, and each group of second traction airbags is externally connected to the air supply system through a connecting pipe.

[0017] The technical effects and advantages of this invention are as follows:

[0018] In this invention, the device injects gas into the inner support airbag through a gas supply system. The special internal structure of the airbag causes the gas to inflate sequentially, pushing the outer bulging airbag to gradually penetrate into the cuff, achieving an automatic positioning function. Subsequently, the gas causes the end of the outer bulging airbag to inflate first and continuously compress the cuff. At the same time, the first traction airbag on the outer bulging airbag inflates synchronously and adheres tightly to the inner wall of the cuff. During the extension of the airbag, it continuously pulls the cuff outward, effectively eliminating wrinkles and reducing manual adjustment time.

[0019] In this invention, the device inflates the second traction airbag through an air supply system. The airbag extends along the inclined storage groove on the outer wall of the conical light-transmitting cover and fits tightly against the inner wall of the garment's hem. Because the airbag extends along an inclined downward direction, it exerts a continuous downward pulling force on the garment during inflation, causing the main body of the garment to naturally tighten and flatten. No segmented operation is required. Once the garment is tightened, the inspector can directly turn on the visible light source inside the conical light-transmitting cover. The light penetrates the cover and the flat garment, enabling a one-time overall inspection and completely avoiding the need for repeated adjustments to the garment. Attached Figure Description

Detailed Implementation

[0029] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0030] Reference Figure 1-7 As shown, the present invention provides a technical solution: a surface defect detection device for cashmere fabric products, including a detection device body 1. The detection device body 1 is composed of several main parts, including a grounding base, a rotating disk, and a slide rail. The rotating disk is rotatably connected to the upper surface of the grounding base. Two sets of conical light-transmitting covers 11 are limited and installed on the slide rail by a sliding member (with limit bolts, which are fixed by the bolts pressing against the slide rail). The sliding member is equipped with a rotating member (the rotating member can adjust the left and right rotation of the two sets of conical light-transmitting covers 11). Each set of rotating shafts of the device is equipped with a damping bearing to maintain relative stability during detection. Two sets of conical light-transmitting covers 11 are movably installed on the upper surface of the detection device body 1. The outer walls of the two sets of conical light-transmitting covers 11 are symmetrically provided with inclined first storage grooves 12. Each set of first storage grooves 12 is equipped with auxiliary components for positioning the garment and smoothing out wrinkles.

[0031] The auxiliary components also include an inner support airbag 2 that passes through the cuff and provides support for it. The outer wall of the inner support airbag 2 is coaxially fitted with an outer bulging airbag 22 for driving the cuff to bulge. The outer wall of the outer bulging airbag 22 is fixed at equal angles around the axis with multiple sets of first traction airbags 23 for pulling the cuff to eliminate wrinkles. Multiple sets of porous partitions 21 for separating the internal space of the inner support airbag 2 are fixed at equal intervals inside the inner support airbag 2. Multiple sets of porous spacer rings 24 are fixed inside the interlayer space between the outer bulging airbag 22 and the inner support airbag 2.

[0032] Each group of porous spacers 21 has multiple sets of pores for gas passage at equal angles around the center on its surface, and the number of pores on the surface of the multiple groups of porous spacers 21 decreases in a stepwise manner from one side to the other.

[0033] The inner support airbag 2 has a connecting air port at the center of the outer wall on the side away from the mounting plate 25, which is connected to the inner space of the outer bulging airbag 22. The interlayer space between the outer bulging airbag 22 and the inner support airbag 2 and the inner space of the inner support airbag 2 are connected to each other as a whole through the connecting air port.

[0034] The distance between two adjacent sets of first traction airbags 23 increases in a stepped manner from one side to the other, and the inner cavity of the first traction airbag 23 is connected to the inner cavity of the outer bulging airbag 22. The inside of the cone-shaped light-transmitting cover 11 is equipped with a visible light generating device 14. When multiple sets of first traction airbags 23 with different distances are close to the inner wall of the cuff.

[0035] Reference Figure 3-7 As shown in this embodiment: the inner support airbag 2 and the outer bulging airbag 22 are both pleated in shape. The pleated inner support airbag 2 and the outer bulging airbag 22 can inflate and extend in a fixed direction after inflation, and then extend into the cuff of the garment. One end of the inner support airbag 2 and the outer bulging airbag 22 is fixedly connected to a mounting plate 25. The mounting plate 25 is fixedly installed inside the first storage groove 12 by bolts.

[0036] Reference Figure 3-7 As shown in this embodiment: the spacing between two adjacent sets of porous spacer rings 24 decreases in a stepped manner from one side to the other. The adjustable spacing of each section is achieved by the stepped decreasing outer bulge 22, so that the fixed point of the cuff is continuously stretched (which varies depending on the stretching spacing), thereby eliminating some wrinkles to a certain extent. Each set of porous spacer rings 24 has multiple sets of through holes for gas passage at equal angles around the center, and the number of air holes on the surface of the multiple sets of porous spacer rings 24 decreases in a stepped manner from one side to the other. The inflation rate of different cavities is adjusted by the change in the number of air holes on the surface of the porous spacer rings 24, thereby achieving the effect of gradual elongation.

[0037] Reference Figure 3-7 As shown in this embodiment: a first one-way valve is installed at the center of the surface of the mounting plate 25, which only allows air to enter the inner support airbag 2 in one direction, and the output end of the first one-way valve is connected to the internal space of the inner support airbag 2. A branch pipe group 26 is fixed on the outer wall of the mounting plate 25 away from the inner support airbag 2, and one set of output ends of the branch pipe group 26 is connected to the input end of the first one-way valve.

[0038] Reference Figure 3-7 As shown in this embodiment: multiple sets of second one-way valves that only discharge air to the external space are fixed around the center on the surface of the mounting plate 25 and in the space between the outer bulging airbag 22 and the inner supporting airbag 2. The output end of each set of second one-way valves is connected to the output end of the corresponding position on the branch pipe group 26. The input end of the branch pipe group 26 is connected to the air supply system through the connecting pipe.

[0039] Reference Figure 3-7 As shown in this embodiment: multiple sets of second storage slots 13 with inclined internal spaces are opened at equal angles around the center on the lower side of the outer wall of the cone-shaped light-transmitting cover 11. Each set of second storage slots 13 has a second traction airbag 3 fixed inside for pulling the hem of the clothes downward.

[0040] Reference Figure 3-7 As shown in this embodiment: the internal volume of each group of second traction airbags 3 is larger than the internal volume of the second storage slot 13, and each group of second traction airbags 3 is externally connected to the air supply system through a connecting pipe.

[0041] Working principle: The inspector first covers the garment with the outer wall of the two sets of conical light-transmitting covers (the cuffs of the garment need to be aligned with the first storage slot 12), and then starts the air supply system to send air into the interior of the internal support airbag 2 through the connecting pipe and branch pipe group 26.

[0042] During the gas supply process, the first one-way valve is in the open state, and each group of second one-way valves is in the closed state. The gas continuously flows through the cavities separated by multiple groups of porous partitions 21. During the flow, the different number of air holes on the surface of each group of porous partitions 21 can distinguish the bulging speed of each group of cavities (specifically, the group of porous partitions 21 closest to the mounting plate 25 has the most air holes, and then the number decreases sequentially towards the other side).

[0043] Therefore, when air is introduced, the cavity closest to the mounting plate 25 of the inner support airbag 2 will bulge first, and then the remaining cavities will bulge in sequence. With the gradual bulging of the inner support airbag 2, the outer bulging airbag 22 will gradually extend into the cuff, which is similar to the action of putting on clothes and then putting them on. This can eliminate the need for manual labor and automatically and quickly position the cuff of the garment, which improves the detection efficiency to a certain extent.

[0044] Next, the gas flows from the inner cavity of the inner support airbag 2 to the inner space of the outer bulging airbag 22 through the connecting air port. Then, the gas continuously passes through the spaces divided by each group of porous spacers 24, inflating the outer bulging airbag 22 section by section. Since the end of the outer bulging airbag 22 inflates first, the first section of the outer bulging airbag 22 will always compress the cuff during the entire process of the inner support airbag 2 driving the outer bulging airbag 22 to extend. At the same time, as the inner cavity of the outer bulging airbag 22 inflates section by section, each corresponding group of first traction airbags 23 inflates together. With the first traction airbags 23 closely attached to the inner wall of the cuff, the continuously extending outer bulging airbags 22 continuously pull the cuff outward with the help of the first traction airbags 23, thereby eliminating most of the wrinkles on the cuff, reducing the workload of the inspection personnel in smoothing out wrinkles, shortening the operation time of this step, and further improving the inspection efficiency to a certain extent.

[0045] Before testing, air is supplied to each group of second traction airbags 3 through the air supply system and connecting pipe. The second traction airbags 3 inflate and extend along the inclined inner wall of the second storage groove 13 to the outer wall of the cone-shaped light-transmitting cover 11. The extended second traction airbags 3 contact the inner wall of the hem of the garment and continuously pull the garment down through the inclined downward path, thereby tightening the garment to a certain extent and ensuring the accuracy of the test.

[0046] During testing, the operator needs to turn on the visible light generating device 14 located inside the conical light-transmitting cover 11. With the help of visible light passing through the conical light-transmitting cover 11 and the clothing, the testing personnel will then conduct the test.

[0047] Finally, after the test is completed, the gas is extracted from the inner support airbag 2, the outer bulging airbag 22, the first traction airbag 23 and the second traction airbag 3 through the gas supply system. During the extraction process, the second one-way valve opens and the first one-way valve closes. After the extraction is completed, each airbag component retracts inward, and the clothing can be removed at this time.

[0048] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
