[0022] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] like Figures 1-5As shown, this embodiment discloses a membrane defect detection device, installed between the unwinding and lamination of membrane 7, for detecting defects in membrane 7 before lamination. The device includes a camera 1, a partition 2, a light strip 3, a light shield 4, a light shielding assembly 5, a tension roller 6, and membrane 7. The camera 1 is located above the partition 2, and the unwinding of membrane 7 passes below the partition 2. The partition 2 is used for workers to stand and adjust the lamination equipment. The camera 1 can take photos of the passing membrane 7 for comparison and detection. When obvious bright or dark areas appear, it can issue an alarm and stop lamination, reminding workers to handle the issue. This embodiment also includes a first guide rail 11, a first slider 111, a second guide rail 12, and a second slider 121. The first slider 111 is installed on the first guide rail 11, and the second guide rail 121 is installed on the first slider 11. 1. The second slider 121 is installed on the second guide rail 12. The first guide rail 11 is set horizontally, and the second guide rail 12 is set vertically to the first guide rail 11. The camera 1 is installed on the second slider 121. The first guide rail 11 is installed on the frame of the composite equipment. By adjusting the position of the first slider 111 on the first guide rail 11, the position of the camera 1 in the horizontal direction can be changed. The first slider 111 can be locked on the first guide rail 11 by bolts. By adjusting the position of the second slider 121 on the second guide rail 12, the position of the camera 1 in the vertical direction can be changed. The camera 1 is located above the middle position of the first light-transmitting groove 21. The camera 1 can be adjusted according to the width of the membrane 7 to be detected, so that the width that the camera 1 can cover can be adjusted to adapt to membranes 7 of different widths for detection.

[0024] The light strip 3, light shield 4, tension roller 6, and membrane 7 are located below the partition 2. There are two tension rollers 6, and the membrane 7 is tensioned by the two tension rollers 6. The membrane 7 is located between the partition 2 and the light strip 3, so that the part of the membrane 7 passing through the partition 2 and the light strip 3 is also in a horizontal state, and the camera 1 can take a clearer picture. The partition 2 is provided with a first light-transmitting groove 21, which extends along the width direction of the membrane 7. The camera 1 can take a picture of the membrane 7 that is lowered through the first light-transmitting groove 21. The brightness of the area of ​​the first light-transmitting groove 21 is significantly higher than the brightness of the rest of the partition 2. The part of the high-brightness strip area is then identified for comparison detection.

[0025] This embodiment also includes two light-shielding components 5, which are installed on the partition 2. Each light-shielding component 5 includes a movable base 51, a fixed shell 52, and a light-shielding baffle 53. The lower end face of the partition 2 is provided with a slide rail 22, which is located on both sides of the first light-transmitting groove 21 and extends along the length of the first light-transmitting groove 21. The movable base 51 is slidably connected to the two slide rails 22 and can slide along the slide rails 22. The upper end face of the movable base 51 is provided with two ear plates 511, and handles 512 are installed on the two ear plates 511. The handles 512 are rotatably connected to the ear plates 511 and can be used to pull the movable base 51. When not in use, the handles can be lowered below the partition 2. On the upper end face of the movable seat 51, there is a support plate 513. The support plate 513 includes a horizontal plate 5131. The horizontal plate 5131 is located above the partition 2. The horizontal plate 5131 is installed with a threaded bolt 514. The lower end of the bolt 514 can abut against the upper end face of the partition 2. When moving the seat 51, the bolt 514 needs to be turned away from the upper end face of the partition 2. After adjusting the movable seat 51, the bolt is tightened to fix the movable seat 51. By adjusting the distance between the two movable seats 51, the light transmission range of the first light transmission groove 21 can be changed. It can be adjusted according to the width of the membrane 7 being tested, reducing the error caused by the empty part when the camera 1 takes pictures and detects, and making the detection process more accurate.

[0026] The fixed housing 52 is installed at both ends of the first light-transmitting groove 21. The two ends of the light-shielding baffle 53 are respectively connected to the fixed housing 52 and the movable seat 51. The light-shielding baffle 53 is a wavy folding plate. The light-shielding baffle 53 is made of dark material and can block the light source below. The fixed housing 52 is hollow inside. The light-shielding baffle 53 is located inside the fixed housing 52. The fixed housing 52 can fold up to accommodate the folded light-shielding baffle 53. When the two movable seats 51 are close to each other, the two light-shielding baffles 53 unfold. The light-shielding baffle 53 can unfold or fold up. The light-shielding baffle 53 blocks part of the first light-transmitting groove 21. The wavy folding plate has good extensibility, which makes it easy to block the strip-shaped first light-transmitting groove 21.

[0027] The light strip 3 extends in the same direction as the first light-transmitting groove 21. The light strip 3 is located below the first light-transmitting groove 21, and the light-emitting surface of the light strip 3 faces the first light-transmitting groove 21. The light strip 3 illuminates the membrane 7 from below, allowing the light to pass through the membrane 7 being tested. The degree of light transmission is used to determine whether the membrane 7 has defects. More preferably, the length of the first light-transmitting groove 21 and the light strip 3 is greater than the width of the membrane 7, ensuring that the entire membrane 7 is within the illumination range of the light strip 3.

[0028] The light shield 4 is located on the outer periphery of the light strip 3. The light shield 4 is shaped like a "Z". The top of the light shield 4 is provided with a second light-transmitting groove 41, which corresponds to the position of the first light-transmitting groove 21. The light shield 4 includes a first light guide plate 411. The first light guide plate 411 is arranged around the edge of the second light-transmitting groove 41. The upper end of the first light guide plate 411 extends towards the partition 2 and is close to the film 7. The lower end of the first light guide plate 411 extends towards the light strip 3 and is close to the light-emitting surface of the lamp body 31. The first light guide plate 411 can form a strip-shaped light-transmitting channel, so that the light emitted by the light strip 3 can be concentrated in the channel formed by the first light guide plate 411, making the light irradiated on the film 7 more concentrated.

[0029] The light-shielding component 5 includes a second light guide plate 54. The two ends of the second light guide plate 54 are respectively fixed to the lower end faces of the two fixed shells 52. The channel formed by the second light guide plate 54 corresponds to the width of the first light-transmitting groove 21. The second light guide plate 54 extends towards the light strip 3. The lower end of the second light guide plate 54 is close to the film 7, so that the first light guide plate 411 and the second light guide plate 54 are connected more closely, reducing light loss. The second light guide plate 54 enables the light transmitted through the film 7 to be concentrated in the channel formed by the second light guide plate 54, making the light transmitted from the first light-transmitting groove 21 more concentrated, and making the camera 1 capture clearer images.

[0030] The light strip 3 includes a light body 31 and two brackets 32. The brackets 32 are located at both ends of the length of the light body 31. The brackets 32 are detachably connected to the light body 31. The side wall of the light shield 4 has multiple ventilation holes 42. The ventilation holes 42 are arranged along the length of the light shield 4. The ventilation holes 42 connect the inside and outside of the light shield 4. The brackets 32 can raise the distance between the light body 31 and the ground. The ventilation holes 42 connecting the two sides can help the light body 31 dissipate heat.
