Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of light boxes for insulating glass production lines, specifically, to a light box for insulating glass production lines. Background Technology

[0002] In the production process of insulated glass, quality inspection of the raw glass sheets and the lamination process is a crucial step in ensuring the performance of the finished product. Whether it is checking for defects such as scratches and bubbles on the glass surface, or inspecting the alignment accuracy of the two glass sheets, clear visual observation conditions are required, which directly affects the product qualification rate and production efficiency.

[0003] Currently, the lighting of insulating glass production lines mostly relies on ambient light or simple lamps. These light sources have obvious shortcomings: the light intensity is unstable and easily affected by weather and time of day. On cloudy or rainy days or during nighttime production, the light brightness drops significantly. Moreover, the angle of illumination from the light source is fixed, making it difficult to cover the entire area of ​​the glass. This results in uneven light and shadow on the glass surface, and some areas may hide defects due to insufficient light, increasing the risk of missed inspections.

[0004] For large-sized insulated glass units (such as those used in building curtain walls), their large surface area limits the illumination range of traditional light sources. Operators must frequently adjust their observation positions to complete a comprehensive inspection, which not only prolongs the inspection time but also risks misjudging defects due to viewing angle deviations. Furthermore, insufficient lighting forces operators to get close to the glass, increasing the probability of secondary contamination from hand contact and affecting the cleanliness of the insulated glass. Therefore, developing a dedicated lightbox adapted for insulated glass production lines to provide stable and uniform illumination has become an urgent need to improve inspection accuracy and production efficiency. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a light box for insulating glass production lines, which solves the technical problem that the lighting of insulating glass production lines in the prior art mostly relies on ambient light or simple lamps in the workshop, and these light sources have obvious deficiencies.

[0031] like Figures 1-3 As shown, a lightbox for an insulating glass production line according to an embodiment of this disclosure includes:

[0032] The enclosure 1 and the observation window 2 are provided at an inclined angle on the surface of the enclosure 1.

[0033] Lighting component 4, which is disposed at the top inside the housing 1;

[0034] A pair of rectangular seats 3 and a support adjustment assembly 5, wherein the rectangular seats 3 are both disposed at the bottom of the housing 1, and the support adjustment assembly 5 is disposed between the rectangular seats 3 and the housing 1;

[0035] The lighting assembly 4 includes a lamp plate 4-1, which is disposed at the top of the housing 1. Connecting rods 4-2 are provided at the four opposite corners of the lamp plate 4-1. The connecting rods 4-2 are movably fitted into the top of the housing 1. An internally threaded block 4-3 is rotatably fitted onto the top of the housing 1. A stud 4-4 is provided on the surface of the lamp plate 4-1, passing through the top of the housing 1 and connected to the internally threaded block 4-3 via a threaded engagement. Elongated holes 4-5 are provided on the top and one side of the housing 1, with a skin 4-6 inserted into each hole. A support plate 4-7 is provided inside the housing 1, fitting against the inner side of the skin 4-6. Pressure plates 4-8, fixed by bolts, are provided on the top and one side of the housing 1, pressing against the surface of the skin 4-6.

[0036] In some examples, to achieve both good lighting effects and height adjustability, a lighting component 4 is designed. This component includes a lamp plate 4-1 located at the top inside the housing 1, with connecting rods 4-2 at the four corners of its surface pointing vertically upwards and movably fitted into guide holes at the top of the housing 1, ensuring smooth and stable movement of the lamp plate 4-1 during lifting and lowering. An internally threaded block 4-3 at the top of the housing 1 is rotatably connected via bearings. Studs 4-4 on the surface of the lamp plate 4-1 pass upwards through the top of the housing 1 and are threaded into the internally threaded block 4-3. Elongated holes 4-5 at the top and one side of the housing 1 provide installation channels for the skin 4-6. After passing through the elongated holes 4-5, the inner side of the skin 4-6 fits against the support plate 4-7, while the outer side is secured by bolts to the pressure plate 4-8 on the surface of the housing 1. The support plate 4-7 provides support for the skin 4-6, preventing it from sagging under its own weight and affecting the lighting effect.

[0037] During adjustment, rotating the internal threaded block 4-3 drives the stud 4-4 to rise and fall via the threaded transmission. The lamp plate 4-1 moves along the connecting rod 4-2 with the screw 5-4, changing the illumination height. The skin 4-6 diffuses the light, making the light inside the housing 1 uniform and avoiding light spots caused by direct light. The pressure plate 4-8 and the support plate 4-7 cooperate to fix the skin 4-6, preventing it from shifting when the lamp plate 4-1 rises and falls. This assembly, through the height-adjustable lamp plate 4-1 and the diffused light skin 4-6, provides a uniform and adjustable brightness illumination environment for insulated glass inspection, improving the accuracy of glass defect identification.

[0038] like Figures 1-3As shown in the figure, the support adjustment component 5 in this embodiment includes a pair of through holes 5-1, which are opened at the lower ends of the two side surfaces of the housing 1. A pair of rolling rods 5-2 are provided on the inner and outer sides of the housing 1. The rolling rods 5-2 are located at the through holes 5-1. A pair of fixed rods 5-3 are connected between the rectangular seats 3. A screw 5-4 is rotatably connected between the fixed rods 5-3. A movable cavity 5-5 is opened in the rectangular seat 3. A pair of guide rods 5-6 are provided in the movable cavity 5-5. A slider 5-7 is slidably connected to both ends of the guide rods 5-6. The upper end surface of the slider 5-7 is rotatably connected to the bottom surface of the housing 1 by a pin and a support rod 5-8. A transmission rod 5-9 is connected between the pair of horizontally opposite sliders 5-7. The transmission rods 5-9 are all connected to the screw 5-4 by threaded engagement.

[0039] In some examples, to achieve stable support for the housing 1 and flexible height adjustment, a support adjustment assembly 5 is designed. This assembly includes through-holes 5-1 at the lower ends of both sides of the housing 1 to provide installation space for the rolling rods 5-2. The two ends of the rolling rods 5-2 are located inside and outside the housing 1, respectively, and can rotate freely. During glass conveying, they contact the glass surface to reduce friction. The fixing rods 5-3 between the rectangular seats 3 are arranged in parallel, and the screw 5-4 is rotatably fitted between the fixing rods 5-3. The moving cavity 5-5 inside the rectangular seat 3 provides moving space for the slider 5-7. The guide rod 5-6 is horizontally fixed inside the moving cavity 5-5, and the slider 5-7 is fitted on the guide rod 5-6 and can slide along the rod. The support rod 5-8 at the upper end of the slider 5-7 is rotatably connected to the bottom surface of the housing 1 by a pin. The transmission rod 5-9 between the sliders 5-7 laterally opposite each other is threadedly engaged with the screw 5-4, and the threads at both ends rotate in opposite directions.

[0040] During adjustment, rotating screw 5-4 causes transmission rod 5-9 to move the laterally opposite slider 5-7 in the opposite direction along guide rod 5-6, which in turn pushes the housing 1 up and down via support rod 5-8. Rolling rod 5-2 remains in contact with the glass as the height of housing 1 changes, assisting in glass transport. Screw 5-4 drives the slider 5-7 to move synchronously, ensuring smooth lifting and lowering of housing 1; guide rod 5-6 limits the offset of slider 5-7, improving adjustment stability. This assembly can accommodate glass of different thicknesses. By adjusting the height of housing 1, the observation window 2 maintains the optimal detection distance from the glass, and the rolling rod 5-2 ensures smooth glass transport.

[0041] For example, such as Figure 3 As shown, the skin 4-6 is laid in an L-shape on the top of the box body 1.

[0042] In some examples, L-shaped skins 4-6 cover the top and one side surfaces of the inner chamber 1, with smooth transitions at the corners. The edges of the skins 4-6 pass through elongated holes 4-5 and are secured by pressure plates 4-8, with the inner side tightly fitted to the support plate 4-7. The L-shaped structure allows light to illuminate the glass simultaneously from the top and sides, eliminating blind spots in the inspection. The smooth transitions at the corners prevent light refraction from creating shadows, resulting in more uniform lighting within the chamber 1 and improving the comprehensiveness of glass defect detection.

[0043] For example, such as Figure 3 As shown, the lamp panel 4-1 uses a D65 light source.

[0044] In some examples, the D65 light source used in light panel 4-1 is a standard daylight source with a stable color temperature of around 6500K. This light source's spectrum is close to natural daylight, accurately reproducing the color and defect characteristics of insulated glass, avoiding misjudgments caused by color deviation. The D65 light source, combined with the soft light effect of skin 4-6, provides an internationally standardized lighting environment for glass inspection, ensuring the accuracy of the test results.

[0045] For example, such as Figure 2 As shown, both ends of the screw 5-4 are provided with screwing blocks 6, and the screwing blocks 6 have a polygonal structure.

[0046] In some examples, the polygonal screw blocks 6 at both ends of the screw 5-4 are integrally formed with the screw 5-4 and can be used with tools such as wrenches. The polygonal structure of the screw blocks 6 facilitates the application of torque, allowing easy rotation of the screw 5-4 to adjust the height of the housing 1. They are symmetrically distributed at both ends of the screw 5-4, making it convenient to operate from both sides, improving the ease of adjustment, and ensuring that the support adjustment assembly 5 can quickly adapt to glass of different thicknesses.

[0047] In actual use: The pushing device moves the rectangular seat 3 to the side of the production line. Rotating the polygonal screw blocks 6 at both ends of the screw 5-4 drives the slider 5-7 to slide along the guide rod 5-6 via the transmission rod 5-9. The support rod 5-8 pushes the housing 1 up and down. The rolling rod 5-2 at the through-hole 5-1 adjusts to fit the glass surface according to the height of the housing 1, ensuring smooth glass transport. Rotating the internal thread block 4-3 causes the stud 4-4 to move the lamp plate 4-1 up and down along the connecting rod 4-2, adjusting the lighting height. The L-shaped skin 4-6 is fixed inside the housing 1 by the pressure plate 4-8, softening and diffusing the D65 light source of the lamp plate 4-1. The insulating glass is fed into the housing 1 via the rolling rod 5-2. The operator inspects the glass for defects through the tilted observation window 2 under uniform lighting. After inspection, the glass is sent out with the rolling rod 5-2. If lighting adjustment is needed, simply rotate the internal thread block 4-3 again.

Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
