Description

Technical Field

[0001] This utility model relates to the field of glass detection technology, specifically to an integrated glass detection alarm device based on multi-sensor feedback. Background Technology

[0002] Glass is an amorphous inorganic non-metallic material, generally made from a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw materials, with the addition of small amounts of auxiliary materials. Its main component is silicon dioxide and other oxides. Glass is widely used in buildings for wind insulation and light transmission; it is a mixture. There are also colored glasses, which exhibit color due to the incorporation of certain metal oxides or salts, and tempered glass, which is produced through physical or chemical methods. Sometimes, some transparent plastics (such as polymethyl methacrylate) are also referred to as plexiglass.

[0003] In the existing technology, when existing glass inspection equipment detects abnormalities such as unevenness on the glass surface, the protrusions still need to be detected manually. Manual inspection is not only time-consuming and labor-intensive, but also increases the factory's labor costs and is very inconvenient to use.

[0004] In view of this, we have launched an integrated glass detection and alarm device based on multi-sensor feedback. Utility Model Content

[0005] The purpose of this invention is to provide an integrated glass detection and alarm device based on multi-sensor feedback to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated glass detection and alarm device based on multi-sensor feedback, comprising: a concave frame, a limiting plate, and detection sensors;

[0007] The concave frame is provided with conveyor wheels at equal intervals inside, and a motor is provided on the side of the concave frame located on one side of the conveyor wheels.

[0008] The limiting plate is set inside the concave frame and is located on the top of the conveyor wheel. The limiting plate is set to limit the glass to be inspected and prevent the glass from shifting randomly. The top of the concave frame is provided with a concave frame, and the concave frame and the concave frame are fixedly set together.

[0009] The detection sensors are evenly spaced on the inner top wall of the concave frame. The detection sensors are bolted to the inner top wall of the concave frame. A detection mechanism is set on the top of the concave frame on one side of the concave frame. The detection plate of the detection mechanism drives the upright and the contact plate to move up so that the contact plate contacts the alarm sensor.

[0010] Preferably, the detection mechanism includes a spring sleeved on the surface of the upright, a side plate connected to the top of the concave frame, the side plate being fixedly connected to the concave frame, and two sets of side plates. A top plate is provided on the top of the two sets of side plates, and the top plate is fixedly connected to the two sets of side plates. The detection plate is slidably connected to the inner side of the two sets of side plates, the upright is connected to the top of the detection plate, the upright is fixedly connected to the detection plate, and the upright passes through the top plate and connects to the contact plate, and the upright is fixedly connected to the contact plate.

[0011] Preferably, a connecting rod is connected to the center of the top of the top plate, and the connecting rod is fixedly connected to the top plate. A positioning plate is connected to the top of the connecting rod, and the positioning plate is fixedly connected to the connecting rod. An alarm sensor is connected to the bottom of the positioning plate by bolts, and the alarm sensor is located above the contact plate.

[0012] Preferably, a limiting block is connected to one side of the surface of the detection plate, and a limiting groove for sliding the limiting block is opened inside the side plate. The limiting groove and the side plate are integrally formed, and the limiting block slides inside the limiting groove to form a limit, so that the detection plate always moves in a vertical state.

[0013] Preferably, an alarm light is connected to one side of the top of the concave frame. The alarm light can be lit up to visually alert staff to any abnormalities in the glass inspection when problems are detected.

[0014] Preferably, the spring is located between the detection plate and the top plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) When the glass comes into contact with the detection plate, if there is an uneven protrusion, the detection plate moves upward and the spring is compressed. The detection plate drives the upright connected to its top and the contact plate to move upward. When the contact plate moves up to contact the alarm sensor, the alarm sensor is triggered and the alarm sensor transmits the alarm signal. At the same time, the alarm light connected to one side of the top of the concave frame receives the signal and lights up to visually remind the staff that there is an abnormality in the glass detection.

[0017] (2) By using the limiting plate located on the top of the conveyor wheel and inside the concave frame, it can strictly limit the position of the glass during glass conveying, prevent deviation, and ensure that the glass passes through the detection area accurately, always maintaining a suitable detection position, avoiding detection errors caused by position deviation, greatly improving detection accuracy and stability, and laying the foundation for obtaining reliable detection results.

[0018] (3) When the glass is detected by the detection sensor, or when the glass surface is uneven and the detection plate moves up and the contact plate comes into contact with the alarm sensor, the alarm system is activated. The alarm sensor transmits the signal and the alarm light on the top of the concave frame lights up. Through both sound and vision, the staff are promptly alerted that the glass detection is abnormal, ensuring that the problem can be quickly detected and dealt with, and reducing production delays and material waste caused by the failure to detect abnormalities in time.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 This utility model provides a technical solution: an integrated glass detection and alarm device based on multi-sensor feedback, comprising: a concave frame 1, wherein a conveyor wheel 2 is provided at equal intervals inside the concave frame 1, and a motor is provided on the side of the concave frame 1 located on one side of the conveyor wheel 2;

[0027] The limiting plate 3 is disposed on the inner side of the concave frame 1 and is located on the top of the conveyor wheel 2. The top of the concave frame 1 is provided with a concave frame 4.

[0028] The detection sensors 6 are evenly spaced on the inner top wall of the concave frame 4 and are bolted to the inner top wall of the concave frame 4. The top of the concave frame 1 is provided with a detection mechanism on one side of the concave frame 4. The detection plate 10 of the detection mechanism drives the upright 12 and the contact plate 13 to move upward so that the contact plate 13 contacts the alarm sensor 16.

[0029] The detection mechanism includes a spring 11 sleeved on the surface of the upright 12, a side plate 7 connected to the top of the concave frame 1, the side plate 7 being fixedly installed with the concave frame 1, and two sets of side plates 7, with a top plate 8 on the top of the two sets of side plates 7, the top plate 8 being fixedly installed with the two sets of side plates 7, the detection plate 10 slidingly connected to the inner side of the two sets of side plates 7, the upright 12 connected to the top of the detection plate 10, the upright 12 being fixedly installed with the detection plate 10, and the upright 12 passing through the top plate 8 and connecting to the contact plate 13, the upright 12 being fixedly installed with the contact plate 13.

[0030] A connecting rod 17 is connected to the top center of the top plate 8. The connecting rod 17 is fixedly connected to the top plate 8. A positioning plate 9 is connected to the top of the connecting rod 17. The positioning plate 9 is fixedly connected to the connecting rod 17. An alarm sensor 16 is connected to the bottom of the positioning plate 9 by bolts. The alarm sensor 16 is located above the contact plate 13.

[0031] The detection plate 10 is connected to a limiting block 15 on one side of its surface. The side plate 7 has a limiting groove 14 for sliding the limiting block 15 inside. The limiting groove 14 and the side plate 7 are integrally formed, and the limiting block 15 slides inside the limiting groove 14 to form a limit, so that the detection plate 10 always moves in a vertical state.

[0032] An alarm light 5 is connected to one side of the top of the concave frame 4. The alarm light 5 is designed to light up when problems are detected, visually alerting staff to any abnormalities in the glass inspection.

[0033] The spring 11 is located between the detection plate 10 and the top plate 8.

[0034] Specifically, during use, the motor on the side of the concave frame 1 is started, and the motor drives the conveyor wheel 2 to rotate. The glass to be tested is placed on the conveyor wheel 2. The glass moves along the length of the concave frame 1 under the drive of the conveyor wheel 2. The limiting plate 3 is set on the top of the conveyor wheel 2 and located inside the concave frame 1. Its function is to limit the position of the glass during the conveying process, prevent the glass from deviating, ensure that the glass can accurately pass through the detection area, and keep the glass in the appropriate detection position to ensure the accuracy and stability of the detection.

[0035] During the glass transport process, it passes under the concave frame 4. Detection sensors 6, evenly spaced on the inner top wall of the concave frame 4, begin to operate. After single-sided grinding of the glass, they acquire a detection image of the glass surface after grinding. Based on preset projection features, they identify the detection image to form a projection image. Cognex In-Sight2000 series detection sensors 6 determine whether the projection image is consistent with a preset projection reference image. If yes, the glass is clamped into a preset qualified area. If no, the deviation between the projection image and the projection reference image is analyzed and used as projection deviation information. Based on the projection deviation information, processing abnormality warning information is determined and output to the terminal held by the management personnel. When the detection sensor 6 detects an abnormality in the glass, it will trigger a subsequent alarm.

[0036] The comparison between the projected image and a preset reference image can be achieved using sensors like the Cognex In-Sight 2000 series mentioned in the text, which have built-in powerful image processing modules. Taking the In-Sight 2000-120Mini as an example, it features a 1 / 3" CMOS imager, supports multiple image modes, and has advanced functions such as optical character recognition and spot detection. After acquiring the image of the glass surface and forming a projected image, these sensors can directly compare the projected image and the reference image within the sensor itself, relying on internal preset algorithms and stored reference image data. This method utilizes the sensor's own processing power to quickly obtain the judgment result, reducing data transmission latency.

[0037] Alternatively, it can be a standalone image processing unit: In complex industrial inspection systems, a dedicated image processing unit (IPU) is often used. The detection sensor 6 transmits the acquired image data to this unit. The IPU, with its powerful computing capabilities and specialized image analysis software, accurately compares the projected image with a preset projection reference image. The advantage of this approach is that it can centrally process data from multiple sensors, and the image processing unit can flexibly upgrade its software algorithms to adapt to different inspection needs, improving the accuracy and adaptability of the judgment.

[0038] Programmable Logic Controllers (PLCs) can also be combined with relevant software: PLCs are widely used in industrial control, and some have image processing extension modules. They can receive image data from sensors and, combined with specialized image analysis software or custom programs, determine the consistency between the projected image and a preset projection reference image. The advantages of PLCs lie in their high stability and reliability, enabling them to work closely with other control components in the entire industrial production system. Upon detecting a glass anomaly, they can promptly trigger other equipment for appropriate processing.

[0039] The glass will gradually move backward and come into contact with the detection plate 10. If it encounters an uneven surface, the detection plate 10 will move upward, causing the upright rod 12 connected to its top to move upward as well. The upright rod 12 passes through the top plate 8 and connects to the contact plate 13, so the contact plate 13 will also move upward with the upright rod 12. The spring 11 is sleeved on the surface of the upright rod 12 and is located between the detection plate 10 and the top plate 8. The spring 11 will then be compressed, storing its elastic properties (the spring 11 is sleeved on the surface of the upright rod 12, and the upright rod 12 can be used to limit the compression of the spring 11). (Or, in a situation where there is no oscillation when the elasticity is restored), when the contact plate 13 moves up to contact the alarm sensor 16, the alarm sensor 16 is triggered and transmits an alarm signal. At the same time, the alarm light 5 connected to the top side of the concave frame 4 lights up after receiving the signal, visually reminding the staff that an abnormality has occurred in the glass inspection. When the inspection is completed or the abnormality is handled, the spring 11 uses its own elasticity to restore its original shape, pushing the inspection plate 10 back to the initial position, preparing for the next inspection and facilitating use.

[0040] The sensor 6 can be from the Cognex In-Sight 2000 series (machine vision sensor), such as the In-Sight 2000-110 Mini and In-Sight 2000-120 Mini, offering different combinations of vision tools, imaging specifications, and communication protocols. Taking the In-Sight 2000-120 Mini as an example, it features a 1 / 3" CMOS imager, supports monochrome and color images, and offers options for autofocus (liquid lens) at 6.2mm or manual focus at 8mm. It provides diverse image modes and advanced functions such as optical character recognition and spot detection, enabling precise image acquisition and analysis of glass surfaces to detect anomalies.

[0041] SICK industrial vision sensor cameras VSPP-3F1122 and VSPP-5F2134 are used for automated inspection. They can capture images of glass, process and analyze the images using their internal algorithms, and determine the size, shape, surface defects, etc. of the glass. They can efficiently detect the quality of glass on glass production inspection lines.

[0042] Hikvision's MV-SC3016C-06M-WBN smart camera features machine vision inspection capabilities, using algorithms to detect glass surfaces. Its pixel count, frame rate, and other parameters meet the requirements for glass surface defect detection, acquiring clear images and accurately identifying minute imperfections, protrusions, and other anomalies on the glass surface.

[0043] The model of alarm sensor 16 can be: (contact sensor) KEYENCE AG-411 contact proximity switch: when the contact plate approaches the AG-411 to a certain distance (reaching the trigger threshold), it can respond quickly and output an alarm signal. It has high sensitivity and reliability and can be stably applied in this integrated device to ensure that an alarm signal is issued in a timely manner when an abnormality in the glass is detected.

[0044] Wholesale CHM6A5M8 non-contact contact sensor: As a contact sensor, when the contact plate comes into contact with the sensor, its internal sensing structure changes, generating an electrical signal output, thereby triggering the alarm system. It has a compact structure and is easy to install in integrated devices.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
