Technical Field
[0001] This utility model relates to the technical field of glass quality testing equipment, specifically a device for detecting defects in tempered glass. Background Technology
[0002] Tempered glass, with its high strength, thermal shock resistance, and dispersed fragments upon breakage, is widely used in building curtain walls, automotive windows, appliance panels, and electronic screens. As application scenarios increasingly demand higher safety and aesthetic quality, defect detection during the production and use of tempered glass has become a crucial step in ensuring product performance.
[0003] A search revealed that this utility model relates to the field of glass quality inspection technology, specifically a tempered glass defect detection device. The device includes a detection frame, a movable column, and driven gears. The upper end of the detection frame has a groove, and bases are fixedly connected to the four corners of the lower end of the frame. Fixed plates are fixedly connected to the front and rear of the upper end of the detection frame. A rotary motor is fixedly connected to the rear end of the rear fixed plate, and a driving gear is fixedly connected to the output end of the rotary motor. Several driven gears are provided, and conveying rods are fixedly connected to the front ends of the driving gears and the several driven gears. Four detection lamps are fixedly connected to the left and right inner walls of the detection frame. A connecting plate is fixedly connected to the upper ends of the two fixed plates. This utility model's tempered glass defect detection device, by incorporating a driving gear and several driven gears, significantly reduces the workload of operators.
[0004] The tempered glass inspection device in the aforementioned patent still has certain shortcomings. Common defects in tempered glass include surface scratches, bubbles, stones, impurities, and edge breakage. Currently, the detection of bubbles and impurities in tempered glass mainly relies on manual inspection. This involves placing the glass under strong light and having inspectors visually observe the defects on the glass surface. However, during the strong light exposure, the lack of an anti-reflective structure at the bottom of the tempered glass makes it easy for some of the strong light to be reflected back onto the glass surface, affecting the user's normal observation and causing visual fatigue for the inspectors, resulting in low work efficiency and difficulty in accurately identifying defects on the glass surface. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a tempered glass defect detection device. This solves the problem that the detection of bubbles and impurities in tempered glass still mainly relies on manual inspection. By placing the glass under strong light, inspectors can visually observe the defects on the glass surface. However, during the strong light exposure, the lack of an anti-reflective structure at the bottom of the tempered glass makes it easy for some of the strong light to be reflected back onto the glass surface, affecting the user's normal observation and causing visual fatigue for the inspectors, resulting in low work efficiency and difficulty in accurately identifying defects on the glass surface.
[0006] This utility model provides the following technical solution: a tempered glass defect detection device, including a detection support platform, a workpiece detection chamber provided on the detection support platform, a lamp holder provided at the middle of the top of the detection support platform, a plurality of defect detection lamps evenly installed at the bottom of the lamp holder, the lamp holder and the detection support platform being connected by a fixed screw, a workpiece limiting component provided on the detection support platform, and a detection anti-reflective component provided on the bottom side of the workpiece limiting component;
[0007] The workpiece limiting assembly includes workpiece support bars symmetrically arranged on both sides of the inner wall of the workpiece detection chamber. The workpiece support bars have workpiece limiting grooves on their sides. Two limiting slide grooves are symmetrically opened on both sides of the inner wall of the workpiece detection chamber. A limiting slider is slidably inserted into each limiting slide groove. The end of the limiting slider is fixedly connected to the side wall of the workpiece support bar.
[0008] The anti-reflective detection component includes a bottom mounting plate disposed at the bottom of the workpiece detection chamber. Two movable grooves are symmetrically opened on the bottom wall of the workpiece detection chamber. Two movable sliders are symmetrically arranged on both sides of the top of the bottom mounting plate. The movable sliders are slidably inserted into the movable grooves. A cotton board slot is opened at the top of the bottom mounting plate. A black pure cotton board is disposed in the cotton board slot. Two rotating connecting columns are symmetrically rotatably arranged on both sides of the top of the bottom mounting plate.
[0009] Preferred technical solution 1: An abutment plate is fitted on the rotating connecting column, and a torsion spring is also fitted on the rotating connecting column.
[0010] Preferred technical solution 2: One end of the torsion spring is connected to the rotating connecting column, and the other end of the rotating connecting column is connected to the abutting plate.
[0011] Preferred technical solution three: The longitudinal sections of the limiting groove and the limiting slider are both trapezoidal shapes that match each other.
[0012] This solution enables the limit slider to slide more stably in the limit groove, preventing the limit slider from slipping out of the limit groove.
[0013] Preferred technical solution four: The black pure cotton board is inserted into the cotton board slot, and the side of the abutting card is located on the side of the top of the black pure cotton board.
[0014] This solution enables the black pure cotton board to be effectively limited and fixed when inserted into the cotton board slot.
[0015] Preferred technical solution five: A baffle is provided at the top of the rotating connecting column.
[0016] This design makes the torsion spring fitted on the rotating connecting column more stable.
[0017] Compared with the prior art, this utility model provides a tempered glass defect detection device with the following beneficial effects: This utility model sets a workpiece limiting component and a detection anti-reflective component on the detection support platform. The workpiece limiting grooves opened on the two workpiece support bars in the workpiece limiting component can limit and support the tempered glass, allowing it to move directly under the defect detection lamp. A black pure cotton board is also set directly under the defect detection lamp. The black pure cotton board, through its own light absorption properties, can greatly reduce the reflection of strong light through the tempered glass, thereby making the user's observation and detection of defects on the tempered glass surface more comfortable, effectively reducing the visual fatigue of the inspector, making the detection and identification of defects on the tempered glass surface more accurate, and effectively improving work efficiency.

[0025] Please see Figure 1-4 ,
[0026] Example 1: A tempered glass defect detection device includes a detection support platform 1, a workpiece detection chamber 2 on the detection support platform 1, a lamp holder 3 at the center of the top of the detection support platform 1, a plurality of defect detection lamps 4 evenly installed at the bottom of the lamp holder 3, the lamp holder 3 and the detection support platform 1 are connected by a fixing screw 5, a workpiece limiting component 6 is provided on the detection support platform 1, and a detection anti-reflective component 7 is provided on the bottom side of the workpiece limiting component 6.
[0027] The workpiece limiting assembly 6 includes workpiece support bars 601 symmetrically arranged on both sides of the inner wall of the workpiece inspection chamber 2. The workpiece support bars 601 have workpiece limiting grooves 602 on their sides. Two limiting slide grooves 603 are symmetrically opened on both sides of the inner wall of the workpiece inspection chamber 2. Limiting sliders 604 are slidably inserted into each limiting slide groove 603. The ends of the limiting sliders 604 are fixedly connected to the side walls of the workpiece support bars 601.
[0028] The anti-reflective testing component 7 includes a bottom mounting plate 701 located at the bottom of the workpiece testing chamber 2. Two symmetrical sliding grooves 702 are formed on the bottom wall of the workpiece testing chamber 2. Two symmetrical sliding blocks 703 are arranged on both sides of the top of the bottom mounting plate 701, and the sliding blocks 703 are slidably inserted into the sliding grooves 702. A cotton board slot 704 is formed at the top of the bottom mounting plate 701, and a black pure cotton board 705 is placed inside the cotton board slot 704. Two symmetrical rotating connecting columns 706 are rotatably arranged on both sides of the top of the bottom mounting plate 701. A contact plate 707 is fitted on the rotating connecting column 706, and a torsion spring 708 is also fitted on the rotating connecting column 706. One end of the torsion spring 708 is connected to the rod body of the rotating connecting column 706, and the other end of the rotating connecting column 706 is connected to the contact plate 707.
[0029] Example 2: The difference between this example and Example 1 is that the longitudinal sections of the limiting groove 603 and the limiting slider 604 are both trapezoidal shapes that cooperate with each other.
[0030] This makes the sliding of the limiting slider 604 in the limiting groove 603 more stable and prevents the limiting slider 604 from slipping out of the limiting groove 603.
[0031] Example 3: The difference between this example and Example 1 is that the black cotton board 705 is inserted into the cotton board slot 704, and the side of the contact plate 707 is located on the side of the top of the black cotton board 705.
[0032] This ensures that the black pure cotton board 705 is effectively limited and fixed when inserted into the cotton board slot 704.
[0033] Example 4: The difference between this example and Example 1 is that a baffle is provided at the top of the rotating connecting column 706.
[0034] This makes the torsion spring 708, which is fitted onto the rotating connecting column 706, more stable.
[0035] In this embodiment, since the existing detection of bubbles and impurities in tempered glass mainly relies on manual inspection, the glass is placed under strong light and inspectors observe the defects on the glass surface with the naked eye. However, during the strong light exposure, the tempered glass lacks an anti-reflective structure at the bottom, which makes it easy for some of the strong light to be reflected onto the glass surface, affecting the user's normal observation and reflecting back to the inspectors, causing visual fatigue, low work efficiency, and difficulty in accurately identifying defects on the glass surface.
[0036] In summary, in practical implementation, when users need to inspect tempered glass for defects, they first need to insert both sides of the tempered glass into the workpiece limiting groove 602 to provide limiting support. Handles are also provided at the ends of the two workpiece support bars 601. After being limited, the tempered glass can be moved directly below the defect detection light 4 by pushing the handles. Since both sides of the workpiece support bars 601 are slidably inserted into the limiting groove 603 via limiting sliders 604, the forward and backward movement of the limited tempered glass is more convenient and smooth. Users can flexibly push it forward and backward according to the inspection situation to fully observe and inspect its surface defects.
[0037] Inside the workpiece inspection chamber 2, there is also an anti-reflective inspection component 7. The bottom mounting plate 701 of the anti-reflective inspection component 7 has a cotton board slot 704 on its top. A black pure cotton board 705 is installed in the cotton board slot 704. The black pure cotton board 705 is made of coarse cotton yarn, which is thick and has many gaps between the fibers. After being dyed with dark black dyes such as sulfur black and reactive black, its absorption rate of visible light can reach more than 90%. The bottom end of the bottom mounting plate 701 is slidably inserted into the sliding groove 702 by a sliding slider 703, and then pushed by the bottom mounting plate 701.
[0038] The black cotton board 705 can be moved directly below the defect detection lamp 4. When the defect detection lamp 4 emits strong light that penetrates the tempered glass, it will shine onto the black cotton board 705. Through the absorption effect of the black cotton board 705, the reflection of strong light can be greatly reduced, making it more comfortable for users to observe and detect defects on the surface of tempered glass. This effectively reduces the visual fatigue of the inspectors, makes the detection and identification of defects on the surface of tempered glass more accurate, and effectively improves work efficiency.
