Description

Technical Field

[0001] This utility model relates to the field of glass inspection technology, and in particular to a reciprocating glass defect scanning and inspection instrument. Background Technology

[0002] Accurate detection of glass defects is crucial in many fields such as glass production, processing, and quality inspection. Chinese utility model patent, authorized announcement number "CN219625322U", discloses a glass defect inspection machine. This utility model has a reasonable structural design, simple structure, and convenient operation. It can not only transport the glass plate to be inspected, but also perform double-sided scanning inspection on the glass plate to be inspected, effectively improving the inspection efficiency and the accuracy of the inspection results.

[0003] While the above-mentioned technical solutions can scan and inspect the top and bottom of the glass during use, they are difficult to effectively inspect the sides of the glass. This means that in actual production, there may be some defects hidden on the non-inspection surfaces, making it impossible to detect defects in the blind spots of side inspection in a timely manner, thus affecting product quality. Therefore, we propose a reciprocating glass defect scanning and inspection instrument. Utility Model Content

This leads to the problem that in actual production, there may be some defects hidden on the non-inspection surface, making it impossible to detect the defects in the blind spot of the side inspection in time, thus affecting the product quality.

The two support plates are threaded onto the outer surface of the bidirectional threaded rod, and the two support plates are slidably connected to the outer surface of the limiting rod. The two side scanning detectors are fixedly installed at the bottom of their respective support plates.

[0009] Preferably, the scanning detection structure further includes a second motor, a second threaded rod, a third limiting rod, a mounting plate, and two top scanning detectors. The second threaded rod and the third limiting rod are rotatably connected inside the defect detection box. The second motor is fixedly installed on the side of the defect detection box near the first motor. The output end of the second motor rotatably extends into the interior of the defect detection box and is fixedly connected to the second threaded rod. The mounting plate is threaded onto the outer surface of the second threaded rod and slidably onto the outer surface of the third limiting rod. The two top scanning detectors are fixedly installed on the mounting plate.

[0010] Preferably, a motor three is fixedly installed on the side of the defect detection box near the motor one. The output end of the motor three extends rotatably into the interior of the defect detection box and is fixedly connected to a threaded rod one.

[0026] Please see Figure 1-4 This utility model provides a technical solution: a reciprocating glass defect scanning and inspection instrument, comprising:

[0027] Roller conveyor 1 and defect detection box 2, with defect detection box 2 fixedly connected inside roller conveyor 1;

[0028] The scanning detection structure is located on the defect detection box 2;

[0029] The scanning detection structure includes two support plates 8, two side scanning detectors 7, a bidirectional threaded rod 9, a limiting rod 10, and a motor 3. The bidirectional threaded rod 9 and the limiting rod 10 are rotatably connected inside the defect detection box 2. The motor 3 is fixedly installed on one side of the defect detection box 2. The output end of the motor 3 extends rotatably into the interior of the defect detection box 2 and is fixedly connected to the bidirectional threaded rod 9. The two support plates 8 are threaded onto the outer surface of the bidirectional threaded rod 9. The two support plates 8 are slidably connected to the outer surface of the limiting rod 10. The two side scanning detectors 7 are fixedly installed at the bottom of the corresponding support plates 8.

[0030] The scanning detection structure also includes a second motor 4, a second threaded rod 13, a third limiting rod 14, a mounting plate 15, and two top scanning detectors 16. The second threaded rod 13 and the third limiting rod 14 are rotatably connected inside the defect detection box 2. The second motor 4 is fixedly installed on the side of the defect detection box 2 near the first motor 3. The output end of the second motor 4 rotatably extends into the interior of the defect detection box 2 and is fixedly connected to the second threaded rod 13. The mounting plate 15 is threaded onto the outer surface of the second threaded rod 13 and slidably fitted onto the outer surface of the third limiting rod 14. The two top scanning detectors 16 are fixedly installed on the mounting plate 15. The two top scanning detectors 16 are symmetrically arranged on both sides of the mounting plate 15 and are installed at an angle on the mounting plate 15.

[0031] A motor 5 is fixedly installed on the side of the defect detection box 2 near the motor 3. The output end of the motor 5 extends into the interior of the defect detection box 2 and is fixedly connected to a threaded rod 11. The threaded rod 11 is rotatably connected to the interior of the defect detection box 2. A limit rod 2 12 is fixedly connected inside the defect detection box 2. A bottom scanning detector 6 is threaded onto the outer surface of the threaded rod 11. The bottom scanning detector 6 is slidably sleeved on the outer surface of the limit rod 2 12. Inlet and outlet are provided on both sides of the defect detection box 2.

[0032] Furthermore, when using this device, the glass is placed on the roller conveyor 1. Driven by the rotation of the rollers, the glass moves along the roller conveyor 1 toward the defect detection box 2 and enters the detection area from the inlet / outlet on one side of the defect detection box 2. First, the motor 4 starts, and its output end drives the threaded rod 13 to rotate inside the defect detection box 2. When the threaded rod 13 rotates, the mounting plate 15 moves horizontally along the limiting rod 14, thereby driving the two top scanning detectors 16 on the mounting plate 15 to move horizontally. The two top scanning detectors 16 are symmetrically arranged on both sides of the mounting plate 15 and are both installed at an angle. During the process of the glass passing through the defect detection box 2, the top scanning detector 16 away from the side scanning detector 7 will scan the top and front of the glass, while the top scanning detector 16 close to the side scanning detector 7 can scan the back of the glass. The threaded rod 13 drives the two top scanning detectors 16 to move back and forth, thereby facilitating uniform scanning and detection of the glass.

[0033] When motor 35 starts, its output end drives threaded rod 11 to rotate. The rotation of threaded rod 11 will cause bottom scanning detector 6 to move back and forth along limit rod 2 12, thereby performing reciprocating scanning detection on the bottom surface of the glass to ensure that no defect location is missed and effectively detect whether there are defects such as unevenness or cracks on the bottom.

[0034] Subsequently, motor 3 starts, and its output end drives the bidirectional threaded rod 9 to rotate. The rotation of the bidirectional threaded rod 9 will drive the two support plates 8 to move in opposite directions along the limit rod 10, thereby adjusting the distance between the two side scanning detectors 7 to adapt to the side detection requirements of glass of different widths, so as to facilitate the two side scanning detectors 7 to scan and detect the two sides of the glass.

[0035] After completing the comprehensive inspection, the glass continues to move on the roller conveyor 1 and is output from the inlet and outlet on the other side of the defect inspection box 2, entering the subsequent process.

[0036] The distance between the two side scanning detectors 7 can be adjusted by the bidirectional threaded rod 9 to adapt to the side inspection requirements of glass of different widths, ensuring that both the left and right sides of the glass are within the inspection range. The two top scanning detectors 16 are installed symmetrically at an angle. When they move back and forth driven by the threaded rod 13, they can scan the top, front and back sides of the glass respectively, avoiding the limitation that the inspection can only cover the top and bottom of the glass, thereby improving the comprehensiveness and accuracy of glass defect detection.
