Description

Technical Field

[0001] This utility model relates to the field of glass cover manufacturing technology, and more specifically, to a method for detecting surface defects in flexible glass covers. Background Technology

[0002] Flexible glass covers are widely used in electronic devices (such as smartphones and tablets). Surface defects (such as scratches, dents, and foreign objects) directly affect the product's appearance, function, and user experience. Inspection can promptly remove defective products, ensuring consistent quality across the entire product line. Currently, flexible glass cover inspection includes automated and semi-automatic surface inspection devices. However, semi-automatic surface inspection still faces the following challenges.

[0003] Existing artificial flexible glass cover surface inspection devices typically consist of a base and a lamp holder. The glass cover is manually rotated for inspection. During manual operation, improper handling (such as picking up or flipping) may cause the glass cover to slip accidentally, resulting in breakage or even shattering. Furthermore, when the flexible glass cover is rotated manually in front of the light source, the speed is inconsistent, and some defects may not be observed during the rapid manual rotation, leading to a decrease in the yield rate.

[0004] To address the aforementioned issues, a method for detecting surface defects in flexible glass covers is proposed. Utility Model Content

[0005] To address the aforementioned technical issues, a method for detecting surface defects in flexible glass covers is provided.

[0006] To achieve the above objectives, the present invention can be implemented using the following technical solutions: This utility model provides a method for detecting surface defects in flexible glass covers, comprising: a base, a vertical shaft fixedly connected to the top of the base, a fixed box provided on the top of the vertical shaft, a rotating frame rotatably connected to the top of the fixed box, a rotating frame rotatably connected inside the rotating frame rotatably, two sliding grooves symmetrically formed at the bottom of the rotating frame rotatably, sliders slidably connected inside the two sliding grooves, clamps fixedly connected to the top of the two sliders, positioning grooves formed on the inner sides of the two clamps, foam embedded inside the two positioning grooves, a bidirectional lead screw rotatably connected to the bottom of the rotating frame rotatably, the two ends of the bidirectional lead screw being threadedly connected to the two sliders respectively, and a knob rotatably connected to one side of the bottom of the rotating frame rotatably, the middle of the knob being fixedly connected to the bidirectional lead screw.

[0007] Preferably, a vertical pole is fixedly connected to the top of the base, a sliding rod is slidably connected to the middle of the vertical pole, a detection light is fixedly connected to the top of the sliding rod, and a bolt is threadedly connected to the top of the vertical pole.

[0008] Preferably, a telescopic shaft is slidably connected to the top of the vertical shaft, and two bolts are threadedly connected to one side of the top of the vertical shaft.

[0009] Preferably, a driven bevel gear is rotatably connected to the inner top of the fixed box, and the driven bevel gear is coaxially fixedly connected to the rotating frame. A driving bevel gear is rotatably connected to one side of the inside of the fixed box, and the driving bevel gear meshes with the driven bevel gear. A knob is rotatably connected to the side of the fixed box near the driving bevel gear, and one end of the knob passes through the fixed box and is fixedly connected to the driving bevel gear.

[0010] Preferably, a protective cover is fixedly connected to one side of the rotating frame one, a worm gear is rotatably connected inside the protective cover, the middle part of the worm gear is fixedly connected to the rotating frame two, a worm is rotatably connected inside the protective cover, the worm meshes with the worm gear, and a knob two is rotatably connected to the side of the protective cover, the knob two is fixedly connected to the worm.

[0011] As described above, the features and advantages of this utility model for detecting surface defects in flexible glass covers are: By setting up the clamps, the glass cover is placed between the two clamps. Then, the knob is rotated until the foam inside the positioning groove contacts the edge of the glass cover and is positioned by the positioning groove. Then, rotating frame one and rotating frame two can be rotated to inspect the glass cover in conjunction with the light from the inspection lamp. Compared with the method of inspecting the glass cover by hand, this helps to improve the safety of the glass cover.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] See Figures 1-5 As shown, this is an embodiment of the present invention, and the method for detecting surface defects in a flexible glass cover will be described in detail below: A method for detecting surface defects in flexible glass covers, such as Figures 1-3 As shown, it includes: a base 1, a vertical shaft 2 fixedly connected to the top of the base 1, a fixed box 3 set on the top of the vertical shaft 2, a rotating frame 4 rotatably connected to the top of the fixed box 3, a rotating frame 5 rotatably connected inside the rotating frame 4, two sliding grooves 6 symmetrically opened at the bottom of the rotating frame 5, sliders 7 slidably connected inside the two sliding grooves 6, clamps 8 fixedly connected to the top of the two sliders 7, positioning grooves 9 opened on the inner side of the two clamps 8, foam 10 embedded inside the two positioning grooves 9, a bidirectional lead screw 11 rotatably connected to the bottom of the rotating frame 5, the two ends of the bidirectional lead screw 11 are respectively threaded to the two sliders 7, a knob 12 rotatably connected to one side of the bottom of the rotating frame 5, and the knob 12 is interference-fitted with the rotating frame 5, the middle part of the knob 12 is fixedly connected to the bidirectional lead screw 11.

[0018] Through the above scheme, the foam 10 can protect the edge of the glass cover plate. After the glass cover plate is placed between the two clamping plates 8, rotating the knob 12 will cause the bidirectional lead screw 11 to rotate. The bidirectional lead screw 11 drives the two sliders 7 to move towards the middle of the bidirectional lead screw 11, so that the two clamping plates 8 are close to the edge of the glass cover plate until the foam 10 inside the positioning groove 9 contacts the edge of the glass cover plate and is positioned by the positioning groove 9. Then the rotating frame 1 4 and rotating frame 2 5 can be rotated to detect the glass cover plate in conjunction with the light of the detection lamp 15.

[0019] Furthermore, such as Figure 1 , Figure 2 as well as Figure 4 As shown, a vertical rod 13 is fixedly connected to the top of the base 1, a sliding rod 14 is slidably connected to the middle of the vertical rod 13, a detection light 15 is fixedly connected to the top of the sliding rod 14, a bolt 16 is threadedly connected to the top of the vertical rod 13, a telescopic shaft 17 is slidably connected to the top of the vertical shaft 2, and a bolt 18 is threadedly connected to one side of the top of the vertical shaft 2.

[0020] With the above method, after unscrewing bolt 18 from the vertical shaft 2, the telescopic shaft 17 can be manually raised and lowered to adjust the height of rotating frame 4 and rotating frame 5. After adjustment, screwing bolt 18 back onto the vertical shaft 2 will press the telescopic shaft 17, thus fixing the height of rotating frame 4 and rotating frame 5. After unscrewing bolt 16 from the vertical rod 13, the length of the slide rod 14 extending from the vertical rod 13 can be manually adjusted to adjust the height of the detection light 15. After adjustment, screwing bolt 16 back onto the vertical rod 13 will press the slide rod 14 for fixation. This allows for flexible adjustment based on the height of the staff and the size of the glass cover to align the detection light 15 at the required height.

[0021] Furthermore, such as Figure 1 as well as Figure 4 As shown, a driven bevel gear 19 is rotatably connected to the inner top of the fixed box 3. The driven bevel gear 19 is coaxially fixedly connected to the rotating frame 4. A driving bevel gear 20 is rotatably connected to one side of the inside of the fixed box 3. The driving bevel gear 20 meshes with the driven bevel gear 19. A knob 21 is rotatably connected to the side of the fixed box 3 near the driving bevel gear 20. One end of the knob 21 passes through the fixed box 3 and is fixedly connected to the driving bevel gear 20.

[0022] Using the above method, the staff can manually rotate knob 21, which will cause the active bevel gear 20 to rotate. Under the action of meshing connection, the active bevel gear 20 will drive the driven bevel gear 19 to rotate, thereby driving the rotating frame 4 to rotate, which in turn will drive the glass cover plate held between the clamping plates 8 to rotate left and right, so as to observe the glass cover plate from different angles.

[0023] Furthermore, such as Figure 1 as well as Figure 5 As shown, a protective cover 22 is fixedly connected to one side of the rotating frame 4. A worm gear 23 is rotatably connected inside the protective cover 22. The middle part of the worm gear 23 is fixedly connected to the rotating frame 5. A worm 24 is rotatably connected inside the protective cover 22. The worm 24 meshes with the worm gear 23. A knob 25 is rotatably connected to the side of the protective cover 22. The knob 25 is fixedly connected to the worm 24.

[0024] With the above method, the staff can manually rotate knob 25, which will cause the worm gear 24 to rotate. When the worm gear 24 rotates, it will drive the worm wheel 23 to rotate under the action of meshing connection. The worm wheel 23 will drive the rotating frame 5 to rotate, thereby causing the glass cover plate held in the clamping plate 8 to rotate back and forth. This allows the staff to inspect the glass cover plate from more angles through the light source of the detection lamp 15.

[0025] Specifically, after unscrewing bolt 18 from the vertical shaft 2, the telescopic shaft 17 can be raised and lowered, thereby adjusting the height of rotating frame 4 and rotating frame 5. After adjustment, screwing bolt 18 back onto the vertical shaft 2 will press the telescopic shaft 17, fixing the height of rotating frame 4 and rotating frame 5. After unscrewing bolt 16 from the vertical rod 13, the length of the slide rod 14 extending from the vertical rod 13 can be adjusted, thereby adjusting the height of the detection lamp 15. After adjustment, screwing bolt 16 back onto the vertical rod 13 will press the slide rod 14 for fixation. This allows for flexible adjustment based on the height of the staff and the size of the glass cover to align the detection lamp 15 at the required height. Then, after placing the glass cover between the two clamping plates 8, rotating the knob 12 will cause the knob 12 to drive the bidirectional lead screw 11 to rotate. The bidirectional lead screw 11 will drive the two sliders 7 to slide towards the middle of the bidirectional lead screw 11, thus... Two clamping plates 8 are positioned close to the edge of the glass cover plate until the foam 10 inside the positioning groove 9 contacts the edge of the glass cover plate, and the glass cover plate is positioned by the positioning groove 9. The operator rotates knob 1 21 by hand, which drives the active bevel gear 20 to rotate. Under the action of meshing connection, the active bevel gear 20 rotates, which in turn drives the driven bevel gear 19 to rotate the rotating frame 4, thereby causing the glass cover plate clamped between the clamping plates 8 to rotate left and right, so as to observe the glass cover plate from different angles. The operator rotates knob 25 by hand, which drives the worm gear 24 to rotate. When the worm gear 24 rotates, it drives the worm wheel 23 to rotate under the action of meshing connection, which in turn drives the rotating frame 2 5 to rotate, thereby causing the glass cover plate clamped in the clamping plates 8 to rotate back and forth, so that the operator can inspect the glass cover plate from more angles through the light source of the detection lamp 15.

[0026] The above description is merely an embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
