DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] like Figures 1 to 5 As shown, an automatic light leakage detection machine for curtain fabric 9 includes a box body 2, the box body 2 includes a feed roller frame 3, a feed port 31, a discharge roller frame 4 and a discharge port 41, one side of the box body 2 has a feed port 31, and the other side has a discharge port 41, the feed roller frame 3 is installed on the side of the box body 2 close to the feed port 31, and the feed roller frame is installed with a first conveying roller 32; the discharge roller frame 4 is installed on the side of the box body 2 close to the discharge port 41, and the discharge roller frame 4 is installed with a second conveying roller 42;

[0025] A first opening and closing plate 21 is hingedly connected to one side of the box body 2 near the feed inlet 31, and a second opening and closing plate 22 is hingedly connected to one side of the box body 2 near the discharge outlet 41. The first opening and closing plate 21 and the second opening and closing plate 22 together close the two sides of the box body 2, leaving only a gap a at the feed inlet 31 for the curtain fabric 9 to enter and a gap b at the discharge outlet 41 for the curtain fabric 9 to be discharged;

[0026] The bottom of the box body 2 has a bottom plate 23, and an invisible light source 24 is installed on the bottom plate 23. The invisible light source 24 is located directly below the curtain fabric 9, with a height lower than the curtain fabric 9 and pointing upward to the lower surface of the curtain fabric 9;

[0027] The box body 2 has a top plate 51 in it, a reinforcing frame 52 is fixedly connected to the top plate 51, a mounting beam 53 is fixedly connected to the reinforcing frame 52, a plurality of fixing seats 54 are arranged and installed on one side of the mounting beam 53 through a first connecting piece, a driving box 55 is installed on the fixing seat 54, a special photosensitive industrial camera 56 is fixedly connected to the lower part of the driving box 55, and the special photosensitive industrial camera 56 is aimed downward at the upper surface of the curtain fabric 9.

[0028] In the present invention, the invisible light source 24 and the special light-sensitive industrial camera 56 are prior art.

[0029] The above structure is adopted, by setting the feed port 31 and the discharge port 41 on both sides of the box body 2, and the gap a of the feed port 31 for the curtain cloth 9 to enter and the gap b of the discharge port 41 for the curtain cloth 9 to exit can only maintain the conveyance of the curtain cloth 9, which is conducive to preventing the external light from entering the box body 2 due to the excessive size of the feed port 31 and the discharge port 41. At the same time, by setting the invisible light source 24 on the bottom plate 23 of the box body 2 to irradiate the back of the curtain cloth 9 upward, it is conducive to using invisible light instead of ordinary visible light source to reduce natural light interference. At the same time, a special photosensitive industrial camera 56 is set on the top mounting beam 53 of the box body 2. The irradiation position of the special photosensitive industrial camera 56 is driven by the driving box 55, which is conducive to aligning the special photosensitive industrial camera 56 with the upper surface of the curtain cloth 9, and is equipped with a special filter to filter visible light, retain invisible light, and improve imaging effect. At the same time, the image captured by the special photosensitive industrial camera 56 can be transmitted to the detection computer for imaging and detection through wires. The detection computer obtains photos and detects through algorithms. If there are some holes and light leakage on the curtain cloth 9, the invisible light source 24 can pass through the holes on the curtain cloth 9 and be detected by the special photosensitive industrial camera 56. Since the special photosensitive industrial camera 56 can filter visible light and retain invisible light, the operator can observe the light leakage position of the hole transmitted by the special photosensitive industrial camera 56 on the detection computer, and then call the detection data through the detection computer, and then print and mark the curtain cloth 9 at the light leakage position through the marking equipment, which is convenient for subsequent operators to handle. It is conducive to greatly improving the quality and accuracy of light leakage detection, distinguishing real light leakage defects and other factors, and preventing the operator from physical damage caused by using visible light for detection, protecting the operator, greatly improving safety, and fully automated detection, without manual judgment, improving the accuracy and efficiency of detection; no darkroom environment is required, reducing the impact on the eyes and mental state of workers. At the same time, managers can monitor the working status and quality in real time.

[0030] In the present invention, an invisible light source 24 is used to illuminate the back side (lower surface) of the fabric, and a special photosensitive industrial camera 56 is used to collect images on the front side (upper surface) of the fabric (only collecting invisible light information transmitted through the light leakage point). If there is no light leakage point, the picture is completely black. If there is, the picture and position of the light leakage can be seen on the detection computer.

[0031] Specifically, if Figures 1 to 5 As shown, a plurality of hinged joints are arranged on the upper side of the box body 2 close to the feed port 31, and the hinged joint has a first connecting portion 61, a transmission shaft 62 and a second connecting portion 63, and the first connecting portion 61 and the second connecting portion 63 are hingedly connected through the transmission shaft 62; the first connecting portion 61 fixes an outer wall of one side of the box body 2, and the second connecting portion 63 fixes a first opening and closing plate 21 that is flipped downward; a plurality of hinged joints are arranged on the upper side of the box body 2 close to the discharge port 41, and the second connecting portion 63 of the hinged joint is also fixedly connected to the second opening and closing plate 22.

[0032] With the above structure, the first opening and closing plate 21 and the second opening and closing plate 22 can be flipped upward and opened. When the box body 2 needs to be opened for inspection and fault diagnosis, it is convenient for the operator to clearly see the working status inside the box body 2, which is convenient for inspection and mechanical debugging.

[0033] like Figures 1 to 5 As shown, the detection width formed by the plurality of special light-sensitive industrial cameras 56 is equal to the width of the curtain cloth 9. The arrangement of this structure is conducive to the complete detection of the curtain cloth 9, greatly improving the accuracy and efficiency of the detection, and preventing the occurrence of missed detection and under-detection.

[0034] like Figures 1 to 5 As shown, the first connecting member is a first bolt 7, and first through holes are provided on both sides of the fixing seat 54. The first bolt 7 passes through the first through holes of the fixing seat 54 and is threadedly connected to the mounting beam 53. By providing the first bolt 7 to install the mounting beam 53 and the fixing seat 54, it is conducive to a reliable connection and a stable structure. If the special light-sensitive industrial camera 56 needs to be replaced, the replacement is more convenient and quick, and the practicality is stronger.

[0035] like Figures 1 to 5 As shown, the specific light source type of the invisible light source 24 is UVA / UVB ultraviolet and infrared light source. With this type of invisible light source 24, no darkroom environment is required, which reduces the impact on the eyes and mental state of workers. At the same time, it can be accurately detected by a special light-sensitive industrial camera 56, which improves the accuracy and efficiency of detection.

[0036] like Figures 1 to 5As shown, the material of the overall frame of the box body 2 is a light-proof high-strength steel material, and the material of the reinforcing frame 52 and the mounting beam 53 is a high-strength steel structure. Through this design, it is beneficial to greatly improve the strength of the device, prevent the device from being damaged, and extend the service life of the device.

[0037] like Figures 1 to 5 As shown, the first opening and closing plate 21 and the second opening and closing plate 22 are symmetrically provided with a rotating handle 211. By providing the rotating handle 211, it is convenient for the operator to open one side of the box body 2 through the first opening and closing plate 21 and the second opening and closing plate 22.

[0038] like Figures 1 to 5 As shown, the bottoms of both sides of the box body 2 are also provided with shading plates 25. By providing the shading plates 25, it is beneficial to also perform good shading effects on both sides of the bottom of the box body 2.

[0039] like Figures 1 to 5 As shown, four fixing legs 8 are installed at the bottom of the box body 2. By setting the fixing legs 8, it is beneficial to better fix the box body 2, and the structure is more stable and reliable.
