Description

Technical Field

[0001] This invention relates to a detection device, mainly used for the detection of glass after drilling. Background Technology

[0002] With the advancement of glass manufacturing technology, back glass panels often require drilling. Currently, laser drilling is the most common technique. However, this process is prone to issues such as incomplete or misaligned holes. Manual inspection during the drilling process can lead to missed defects, resulting in defective products with incomplete holes entering the next stage. Furthermore, existing inspection devices frequently err on the side of glass vibration during testing. Therefore, developing a high-efficiency, low-cost drilling inspection device is a key focus for many glass manufacturers.

[0003] An existing patent (application number: CN202323351034.9) discloses an inspection device for perforated glass. It includes a glass conveyor roller conveyor on which perforated glass to be inspected is transported. The device is characterized by at least two frames spanning laterally on the glass conveyor roller conveyor. Each frame is equipped with a set of photoelectric switches, the detection direction of which corresponds to the glass conveyor roller conveyor. As the perforated glass to be inspected moves past the two frames, multiple holes on the perforated glass pass sequentially through the two sets of photoelectric switches on the two frames. This invention uses photoelectric switches and a control system for detection, identification, and defect alarm. The detection process does not affect normal production line operation. It has a simple structure, is easy to use, and online detection does not affect production progress, effectively detecting defects in perforated glass. However, this device increases costs by using photoelectric switches for light detection, and the measurement errors caused by vibration during glass transport on the roller conveyor are difficult to resolve. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a glass drilling detection device with low error rate and good detection effect.

[0005] Specifically, a glass drilling detection device includes a slider, a lifter, a fixed block, a contact element, a spring buffer rod, a probe, a U-shaped groove photoelectric switch, and a sponge anti-shake buffer pad. The slider is mounted on a horizontal slide rod and can slide horizontally along the rod. A lifter for vertical movement is installed at the bottom of the slider. A vertical "L"-shaped fixed block is installed on the lifter. A horizontal U-shaped groove photoelectric switch is installed on the top side of the fixed block, and a probe connecting block is installed on the bottom side of the fixed block. The probe connecting block has a square structure with a vertical spring buffer rod installed on its upper surface. A contact element is installed on the top of the spring buffer rod, and a vertical probe rod is installed on its lower surface. The bottom end of the probe rod is a flat cylindrical probe. A pair of connecting rods are provided on the bottom surface of the slider near the fixed block, and a horizontal sponge anti-shake buffer pad is provided at the bottom of the connecting rods. An air washing device is installed on the bottom surface of the slider away from the fixed block.

[0006] The glass inspection process begins. The drive unit of the transmission equipment below the machine starts, causing the transmission wheel on the rotating shaft to rotate. The perforated glass is horizontally transported through the transmission wheel. At the same time, the inspection device starts, and the air washing device is activated to blow away dust and glass debris from the glass surface to prevent subsequent scratches. Then, a sponge anti-vibration buffer pad is pressed on the glass surface to prevent deviations caused by vibration. The lifter starts, and the fixed block moves up and down to adjust the position of the front probe above the glass surface. When a perforation is encountered, the lifter descends. Normally, if there is a perforation, the device will not send a signal. If there is no perforation or the position is off, the elliptical probe of the probe cannot descend, triggering the upper spring buffer rod to move upward, causing the top contact piece to move upward, triggering the U-slot photoelectric switch's U-slot trigger signal alarm, indicating that there is a problem with the inspected glass.

[0007] Furthermore, a horizontal sensing plate is provided on the side of the probe connecting block, and above the sensing plate is the U-shaped groove of the U-shaped groove photoelectric switch.

[0008] Furthermore, the flat cylindrical probes come in various shapes such as round, square, and oval, allowing for the removal and replacement of appropriate probes based on the shape of the glass hole.

[0009] Furthermore, a rubber ring is wrapped around the bottom side of the flat cylindrical probe, and both the rubber ring and the probe can be replaced according to the size of the glass hole.

[0010] Furthermore, there is an elliptical rubber probe at the center of the bottom surface of the flat cylindrical probe.

[0011] Furthermore, the fixing block has a hollow structure, with signal lines inside connecting to the U-shaped slot photoelectric switch, the lifting device, the air washing device, and the signal lines connecting to the external control system.

[0012] Furthermore, the connecting rod is equipped with a telescopic device that can be adjusted according to different glass thicknesses to ensure that the sponge anti-shake buffer pad can press down on the perforated glass from above.

[0013] Furthermore, the bottom of the air washing device is equipped with a set of downward-propelling jet heads.

[0014] The beneficial effects of this utility model are:

[0015] 1. Install anti-shake buffer device to reduce the shaking of the glass during transmission and ensure the accuracy of the test.

[0016] 2. Replaceable probes are set according to the diameter of the glass hole, which can detect whether a hole has been drilled and whether the hole diameter meets the standard.

[0017] 3. Using an oval-tipped rubber probe can effectively prevent the glass surface from being scratched.

[0018] 4. The detection probe can be replaced with different shapes, and can be used to detect and explore glass holes of different shapes.

[0019] 5. Install an air washing device to blow away debris and dust from the glass surface, preventing subsequent components from scratching the surface. Attached Figure Description

[0028] Example 1:

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, a glass drilling detection device includes a slider 1, a lifter 2, a fixing block 3, a contact element 4, a spring buffer rod 5, a probe 8, a U-shaped groove photoelectric switch, and a sponge anti-shake buffer pad 12. The slider 1 is mounted on a horizontal slide rod 17 and can slide horizontally along the rod. A lifter 2 for vertical lifting is installed at the lower part of the slider 1. A vertical "L"-shaped fixing block 3 is installed on the lifter 2. A horizontal U-shaped groove photoelectric switch 10 is installed on the top side of the fixing block 3, and a probe connecting block 6 is installed on the bottom side of the fixing block 3. The fixing block 3 has a hollow structure and contains signal lines connecting the U-shaped groove photoelectric switch 10, the lifter 2, and the air washing device 14. The signal lines 13 are connected to an external control system. A horizontal sensing plate 4-1 is provided on the side of the probe connecting block 6. Above the sensing plate 4-1 is the U-shaped groove 10-1 of the U-shaped groove photoelectric switch 10. The probe connecting block 6 has a square structure and a vertical spring buffer rod 5 is installed on its upper surface. The spring buffer rod 5 has a contact element 4 at its top and a vertical probe 7 on its lower surface. The bottom of the probe 7 is a flat cylindrical probe 8, which can be round, square, or elliptical. The probe can be disassembled and replaced with a suitable probe according to the shape of the glass hole. A rubber ring 8-1 is wrapped around the bottom side of the flat cylindrical probe 8. Both the rubber ring 8-1 and the probe 8 can be replaced according to the size of the glass hole. There is an elliptical rubber probe 9 at the center of the bottom surface of the probe 8. The bottom surface of the slider 1 is equipped with a pair of connecting rods 11 near the fixed block 3. A horizontal sponge anti-shake buffer pad 12 is provided at the bottom of the connecting rods 11. The connecting rods 11 are equipped with a telescopic device that can be adjusted according to different thicknesses of glass to ensure that the sponge anti-shake buffer pad 12 can press down on the perforated glass 19. The bottom surface of the slider 1 is equipped with an air washing device 14 away from the fixed block 3. The bottom of the air washing device 14 is equipped with a set of downward-propelling air jets 14-1.

[0030] When the glass inspection process begins, the drive unit 15 of the transmission equipment below the device starts, driving the transmission wheel 16 on the rotating shaft 18 to rotate. The perforated glass 19 is horizontally transmitted through the transmission wheel 16. At the same time, the inspection device starts, and the air washing device 14 is turned on to blow away the dust and glass debris on the glass surface to prevent subsequent devices from scratching the glass surface. Then, the sponge anti-shake buffer pad 12 is pressed on the glass surface to prevent vibration and deviation. The lift 2 starts, and the fixing block 3 moves up and down to adjust the front probe 8 to be positioned above the glass surface. When a perforation position is encountered, the lift 2 descends. Normally, if there is a hole, the device will not send a signal. If there is no hole or the position is off, the elliptical probe 9 of the probe 8 cannot descend, triggering the upper spring buffer rod 5 to move upward, driving the top contact piece 4 to move upward. The sensing plate 4-1 enters the U-shaped groove 10-1 of the U-shaped groove photoelectric switch 10 and triggers a signal alarm, indicating that the inspected glass has a problem.
