Description

Technical Field

[0001] This utility model relates to the field of glass processing equipment technology, and in particular to a glass defect indication device. Background Technology

[0002] In the glass manufacturing process of key sectors such as photovoltaics, float glass, and automobiles, glass may encounter quality problems such as edge dimensional errors and localized surface deformation at various stages. To address these issues, many glass manufacturers have introduced visual inspection technology to identify glass defects and thus control the quality of the glass production process. While traditional visual inspection technology can accurately identify and report defect information on a display screen, its limited display size makes it inconvenient for on-site defect location. Even when defective glass can be identified, it's difficult to quickly and directly locate these defects on the glass. Ultimately, personnel still need to rely on screen comparison and visual inspection to find and confirm the corresponding flaws on the actual glass, resulting in low efficiency and a lack of intuitiveness. Therefore, developing inspection equipment that intuitively and efficiently indicates the location of defects on glass has become an urgent need. Utility Model Content

[0003] This invention provides a glass defect indicator device, which aims to improve the efficiency and lack of intuitiveness in the existing glass defect identification process.

[0004] To achieve the above objectives, the glass defect indicator proposed in this utility model includes:

[0005] A conveying mechanism for transporting horizontally placed glass plates;

[0006] A visual inspection mechanism, located above the conveying mechanism, is used to detect defects in the glass plate and generate defect location information;

[0007] A defect marking mechanism is used to receive the defect location information and mark the defects on the glass plate according to the defect location information;

[0008] The defect marking mechanism includes a plurality of marking components spaced apart along the width direction of the glass plate, a liquid delivery component for providing marking liquid to the plurality of marking components, and a pipe assembly connecting the plurality of marking components to the liquid delivery component;

[0009] The marking assembly is located above the conveying mechanism, and the marking assembly includes a nozzle for spraying marking liquid onto a glass plate and a solenoid valve for controlling the opening and closing of the nozzle.

[0011] In some embodiments, the marking assembly further includes a universal bamboo tube connecting the nozzle and the liquid supply tube.

[0012] In some embodiments, the liquid delivery assembly includes a reservoir for storing the labeled liquid and a pump for drawing the labeled liquid from the reservoir.

[0013] In some embodiments, the piping assembly includes a main pipe connecting the pump and a secondary pipe connecting the main pipe to a plurality of the marking assemblies; there are a plurality of secondary pipes, and at least one end of each secondary pipe is connected to a marking assembly.

[0014] In some embodiments, the glass defect indicator further includes a mounting frame, which includes two columns respectively disposed on both sides of the conveying mechanism, and a first crossbeam and a second crossbeam connecting the two columns; the first crossbeam is located above the second crossbeam; a plurality of the marking components are fixed to the lower end of the second crossbeam; and the secondary pipe is disposed along the length direction of the second crossbeam.

[0015] In some embodiments, the visual inspection mechanism is disposed on the first crossbeam; the visual inspection mechanism is located above the plurality of the marking components; the visual inspection mechanism and the marking components are arranged sequentially along the direction in which the glass plate is conveyed by the conveying mechanism.

[0016] In some embodiments, the visual inspection mechanism includes a plurality of visual inspection components, which are spaced apart along the length of the first crossbeam.

[0019] The beneficial effects of this utility model are as follows: This utility model utilizes a conveying mechanism to horizontally transport glass plates. During transport, the glass plates pass through a vision inspection mechanism. After detecting defects on the glass plates, the vision inspection mechanism generates defect location information and sends it to a defect marking mechanism. Based on the defect location information, the defect marking mechanism precisely controls the opening and closing of the solenoid valve in the marking component at the corresponding position, allowing the nozzle to spray marking liquid onto the defect on the glass plate. This results in a colored adhesive liquid adhering to the glass plate, achieving intuitive marking of the defect location. This allows operators to quickly and intuitively discover defects on the glass, significantly improving the efficiency of defect identification. This utility model can achieve intuitive indication of defects on glass with relatively low cost and simplified control methods. It enables operators to easily discover and handle defects without screen comparison, significantly improving the working efficiency of the production line and the product quality control capability.

[0028] This embodiment proposes a glass defect indicator device 100, referring to... Figures 1 to 3 ,include:

[0029] Conveying mechanism 1, used to convey horizontally placed glass plate 200;

[0030] The visual inspection mechanism 2 is located above the conveying mechanism 1 and is used to detect defects in the glass plate 200 and generate defect location information.

[0031] The defect marking mechanism 3 is used to receive defect location information and mark the defects on the glass plate 200 according to the defect location information;

[0032] The defect marking mechanism 3 includes a plurality of marking components 31 spaced apart along the width direction of the glass plate 200, a liquid delivery assembly 32 for providing marking liquid to the plurality of marking components 31, and a pipe assembly 33 connecting the plurality of marking components 31 to the liquid delivery assembly 32.

[0033] The marking assembly 31 is located above the conveying mechanism 1. The marking assembly 31 includes a nozzle 311 that sprays marking liquid onto the glass plate 200 and a solenoid valve 312 that controls the opening and closing of the nozzle 311.

[0034] This embodiment utilizes a vision inspection mechanism 2 to quickly and accurately detect defects in the glass plate 200 transported on the conveying mechanism 1, generating defect location information. The defect marking mechanism 3 includes multiple marking components 31 spaced apart along the width of the glass plate 200, capable of covering the area of ​​the glass plate 200 to be marked and simultaneously marking multiple defects on the glass plate 200. The defect marking mechanism 3 is electrically connected to the vision inspection mechanism 2. After receiving the defect location information, the defect marking mechanism 3 directly controls the solenoid valve 312 on the corresponding marking component 31, causing the nozzle 311 to spray marking liquid onto the defects in the glass plate 200, ensuring that all defects are marked in a timely manner. The solenoid valve 312 controls the on / off state of the nozzle 311, flexibly and precisely controlling the timing and quantity of marking as needed, improving the controllability of marking. The liquid delivery component 32 provides marking liquid to the multiple marking components 31 to ensure the stability of the marking. The pipeline component 33 connects the multiple marking components 31 to the liquid delivery component 32, allowing the marking liquid to be smoothly delivered to each marking component 31. Compared to existing dispensing machines and other equipment, this embodiment enables automated detection and marking of defects on glass at a relatively low cost and with simplified control. Operators can easily identify and address defects without needing to compare against a screen, improving defect identification efficiency and enhancing production line efficiency and product quality control.

[0035] Furthermore, the marking assembly 31 also includes a liquid supply pipe 313 connecting the nozzle 311 to the pipe assembly 33, and a flow regulating valve 314 is provided on the liquid supply pipe 313. In this embodiment, the flow regulating valve 314 on the marking assembly 31 can precisely adjust the flow rate of the marking liquid according to different glass defect conditions and marking requirements. For defects with small areas, a smaller flow rate can be used for marking to avoid the marking being too concentrated and affecting subsequent observation and processing of the defect. For defects with larger areas or more obvious features, the flow rate can be appropriately increased to ensure that the marking is clearly visible. By reasonably adjusting the flow rate, waste of marking liquid can also be avoided. Under the premise of ensuring that the marking is clearly identifiable, the amount of marking liquid used can be reduced as much as possible, thereby reducing production costs. In addition, when the liquid pressure in the pipe assembly 33 changes, the flow regulating valve 314 can be adjusted accordingly to maintain a stable flow rate of marking liquid at the nozzle 311, ensuring the normal operation of the marking work.

[0036] Furthermore, the marking assembly 31 also includes a universal joint tube 315 connecting the nozzle 311 and the liquid supply pipe 313. The universal joint tube 315 can be bent and rotated in multiple directions, allowing for flexible adjustment of the position and angle of the nozzle 311 according to actual needs, ensuring that the nozzle 311 can accurately mark defects on the glass plate 200. In addition, the universal joint tube 315 is easy to install and maintain, improving the reliability and stability of the device.

[0037] Furthermore, the liquid delivery assembly 32 includes a storage tank 321 for storing the labeling liquid and a pump 322 for drawing the labeling liquid from the storage tank 321. In this embodiment, the labeling liquid is a colored adhering liquid. The storage tank 321 centrally stores the labeling liquid, facilitating liquid management, monitoring, and timely replenishment or replacement. Additionally, the labeling liquid can be filtered, stirred, or otherwise treated in the storage tank 321 to ensure stable performance. The pump 322 is a small water pump 322, serving as an independent component; if it malfunctions, it can be replaced or repaired separately, offering convenience and speed.

[0038] Furthermore, the piping assembly 33 includes a main pipe 331 connecting to the pump 322, and secondary pipes 332 connecting the main pipe 331 to multiple marking components 31. Multiple secondary pipes 332 are present, and at least one end of each secondary pipe 332 is connected to a marking component 31. In this embodiment, the liquid supply pipe 313 of the marking component 31 is connected to the piping assembly 33 via a tee pipe 316, at least one end of which is connected to a secondary pipe 332. Multiple marking components 31 are connected in series via multiple secondary pipes 332. The tee pipe 316 can evenly distribute the marking liquid in the main pipe 331 or secondary pipes 332 to each marking component 31, ensuring a stable liquid supply to each marking component 31. When it is necessary to add a marking component 31, the system can be easily expanded by connecting a new tee pipe 316 and a marking component 31 to the existing secondary pipe 332, without requiring large-scale modifications to the entire piping assembly 33, thus improving the scalability and adaptability of the device.

[0039] Furthermore, the glass defect indicator device also includes a mounting frame 4, which includes two columns 41 respectively disposed on both sides of the conveying mechanism 1, and a first crossbeam 42 and a second crossbeam 43 connecting the two columns 41. The first crossbeam 42 is located above the second crossbeam 43. Multiple marking components 31 are fixed to the lower end of the second crossbeam 43. The secondary pipe 332 is arranged along the length direction of the second crossbeam 43. In this embodiment, the arrangement of the first crossbeam 42 and the second crossbeam 43 gives the mounting frame 4 a layered structure, which can reasonably and centrally arrange the positions of the visual inspection mechanism 2 and the marking components 31. When it is necessary to adjust the position or height of the marking components 31, it can be achieved by adjusting the length of the second crossbeam 43 or its height on the mounting frame 4. Arranging the secondary pipe 332 along the length direction of the second crossbeam 43 makes the layout of the secondary pipe 332 more neat and orderly, providing an installation position for the secondary pipe 332 while also supporting and protecting it.

[0040] Furthermore, the visual inspection mechanism 2 is mounted on the first crossbeam 42. The visual inspection mechanism 2 is located above the multiple marking components 31. The visual inspection mechanism 2 and the marking components 31 are arranged sequentially along the direction in which the glass plate 200 is conveyed by the conveying mechanism 1. In the conveying direction of the glass plate 200, the visual inspection mechanism 2 is positioned in front, and the marking components 31 are positioned behind. The visual inspection mechanism 2 and the marking components 31 are spatially separated, allowing sufficient time for the defect marking mechanism 3 to control the marking components 31. First, the location of defects on the glass plate 200 is determined by the visual inspection mechanism 2. When the glass plate 200 reaches the marking components 31, the marking components 31 then mark the glass plate 200. The required position and height of the visual inspection mechanism 2 can be achieved by adjusting the length of the first crossbeam 42 or its height on the mounting bracket 4.

[0041] Furthermore, the visual inspection mechanism 2 includes multiple inspection vision components 21, which are spaced apart along the length of the first crossbeam 42. This spacing increases the inspection coverage area, ensuring comprehensive inspection of the glass plate 200. The multiple inspection vision components 21 can also complement and verify each other, improving the reliability of the inspection. In some embodiments, the inspection vision components 21 include an industrial camera, a lens, and a light source.

[0042] Furthermore, the conveying mechanism 1 includes a transmission wheel assembly 11 for placing the glass plate 200, a drive assembly 12, a bracket 13, and a drive shaft 14 mounted on the bracket 13. The drive assembly 12 is connected to the transmission wheel assembly 11 via the drive shaft 14. The bracket 13 is used to mount the drive shaft 14, the transmission wheel assembly 11, and the drive assembly 12. The transmission wheel assembly 11 is used to place the glass plate 200 and is mounted on the drive shaft 14, driving synchronously with the drive shaft 14, which is horizontally positioned. In this embodiment, a rotating shaft is also vertically positioned. The drive assembly 12 drives the rotating shaft to rotate, which in turn drives the drive shaft 14 to rotate, which in turn drives the transmission wheel assembly 11 to rotate, thereby moving the glass plate 200 forward. The transmission wheel assembly 11, drive assembly 12, drive shaft 14, and rotating shaft are relatively independent, facilitating maintenance and repair.

[0043] Furthermore, the transmission wheel assembly 11 includes a plurality of transmission wheels 111 passing through the transmission shaft 14. The plurality of transmission wheels 111 are spaced apart along the length direction of the transmission shaft 14. In this embodiment, the transmission wheels 111 are vertically arranged on the transmission shaft 14. The arrangement of multiple transmission wheels 111 makes the transmission wheel assembly 11 more adaptable. By increasing the number of transmission wheels 111 and the length of the transmission shaft 14, it can accommodate glass of different sizes, thus improving the scalability of the device.
