Description

Technical Field

[0001] The utility model relates to the technical field of automated detection. Background Art

[0002] As the market prospects of bendable mobile phones are getting better and better, the demand for ultra-thin glass is also increasing. At the same time, the production and processing costs and quality of ultra-thin flexible glass have become the focus of people's attention. Product quality inspection is one of the most important links in the entire production process. At present, most companies are still at the stage of manual visual inspection in terms of product inspection, resulting in the largest proportion of inspection personnel on the production site, high labor costs, and the defects of ultra-thin glass are microscopic. Long-term concentration of human eyes will lead to decreased vision.

[0003] For example, the public document with publication number CN211043189U, publication date 2020-07-17, and patent name "A device for visual detection of ultra-thin glass defects" discloses a device for visual detection of ultra-thin glass defects, including a darkroom, a fixed glass device is arranged directly above the darkroom, and the ultra-thin glass sample is fixed at the lower end of the fixed glass device; light source systems are arranged on both side edges of the ultra-thin glass sample, and the light of the light source system can be illuminated in parallel on the surface of the ultra-thin glass sample.

[0004] At present, similar visual inspection devices are used. In the process of ultra-thin flexible glass inspection, defects on the glass are observed manually with the naked eye. The human eye has a slow observation efficiency, and long-term focus on strong light can cause great damage to the eyes. In addition, an inspector inspects a small amount of glass per day, and the human eye has a small observation range. Most of the defects of ultra-thin glass are microscopic, and they will be missed with a slight negligence, resulting in product quality problems. In addition, the labor cost caused by large shipments is relatively high. This patent is to invent a device for automatically detecting defects in ultra-thin glass to replace manual inspection of glass in order to reduce the workload of inspectors, save corporate production costs, improve inspection efficiency, and more stringent quality control.

[0018] The following is a further detailed description of the specific implementation methods of the present invention, such as the shapes and structures of the components involved, the relative positions and connection relationships between the components, the functions and working principles of the components, the manufacturing process and the operation and use methods, etc., through the description of the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention.

[0019] The glass detection system consists of two rotating devices with the same structure. The two rotating devices are placed adjacent to each other and can serve as backup equipment for each other or be used for synchronous detection. They can provide more reliable protection for glass detection work. The glass detection system is particularly suitable for detecting ultra-thin flexible glass. The entire system is preferably set in a sealed environment and equipped with FFU (fan filter system) to ensure that the equipment is not contaminated by dust and prevent interference with the detection results.

[0020] The two rotating devices are introduced below, wherein the loading rotating seat 5 is a base that rotates horizontally, and two symmetrically arranged loading platforms 4 are fixed on the loading rotating seat 5 by a bracket. The bracket can be in the form of a connecting rod, which is horizontally fixed on the loading rotating seat 5 and extends symmetrically in opposite directions. Two loading platforms 4 are fixed at the ends of the brackets respectively. The loading platforms 4 are horizontally arranged plate-like structures. The loading platforms 4 are used to place glass products to be inspected. The loading stations 3 and the inspection stations A6 are symmetrically arranged on the rotating path of the loading stations 4. The inspection station A6 is provided with an inspection mechanism 7 for obtaining image information of the glass products. The symmetrical arrangement is to rotate the glass on the loading stations 3 and 4 to the inspection station A6. When one product is being photographed, another product can be loaded, thereby improving work efficiency. In addition, the loading position is separated from the photographing position to ensure the cleanliness of the loading position. A loading robot 2 is provided next to the loading station 3. The loading robot 2 is responsible for grabbing a stacked product and placing it on a rotatable loading table 4. A stacking station 1 for stacking glass products to be inspected is provided in the activity area of ​​the loading robot 2. The glass products to be inspected can be neatly placed in the stacking station 1 in advance.

[0021] Similarly, the unloading rotating seat 11 is a base that rotates in the horizontal direction. Two symmetrically arranged unloading tables 10 are fixed on the unloading rotating seat 11 through a bracket. The bracket can also be in the form of a connecting rod, which is horizontally fixed on the unloading rotating seat 11 and extends symmetrically in opposite directions. Two unloading tables 10 are fixed at the ends of the brackets. The unloading tables 10 are horizontally arranged plate-like structures. The unloading tables 10 are used to place glass products to be inspected. Unloading stations 13 and inspection stations B12 are symmetrically arranged on the rotation path of the unloading table 10. The inspection station B12 is provided with a detection mechanism 7 for obtaining image information of the glass product. The symmetrical arrangement is to rotate the glass on the unloading table 10 at the loading station 3 to the inspection station B12. When one product is being photographed, another product can be unloaded, which improves work efficiency. The loading position is separated from the photographing position to ensure the cleanliness of the unloading position. A unloading robot is provided next to the unloading station 13. The unloading robot is responsible for grabbing a piece of inspected product on the unloading table 10 and placing it on the unloading station 15. A unloading station 15 for stacking inspected glass products is provided in the activity area of ​​the unloading robot. The unloading station 15 can have two different placement areas, one is a qualified product placement area, and the other is an unqualified product placement area.

[0022] The intersection area of ​​the rotation path of the unloading platform 10 and the rotation path of the loading platform 4 is the transfer station 8, wherein the intersection area needs to ensure that there is no interference between the unloading platform 10 and the loading platform 4, and there is a certain gap when intersecting, and the transfer station 8 is used to transfer the glass products to be tested on the loading platform 4 to the transfer device on the unloading platform 10. The transfer mechanism is a mechanical arm with a vacuum adsorption mechanism, which can also be manually operated.

[0023] The detection mechanism 7 includes a light source for illuminating the glass product to be detected, and an industrial camera for capturing the surface image information of the glass product to be detected. The industrial camera can cooperate with the light source to capture clear glass defects. There are generally multiple industrial cameras, which can collect image information from different angles to ensure the reliability of detection. The detection mechanism 7 transmits the acquired signal to the PLC. The PLC device is the master control device of the entire system. It can be equipped with corresponding detection software to identify the acquired image and determine whether it is qualified. For example, the detection pictures of the glass on the two stages are spliced ​​to obtain the image of the entire glass. It can also be detected by manual observation of the screen, which is slightly less efficient than automated detection. The PLC is connected and communicated with the loading manipulator 2, the loading rotating seat 5, the detection mechanism 7, the unloading rotating seat 11, the unloading manipulator 14, and the transfer mechanism, and can coordinate the entire system to work.

[0024] By designing two workstations, the inspection station B12 and the inspection station A6 can be used as backup inspection stations for each other, so that production will not be delayed in case of maintenance or failure. The inspection station A6 and the inspection station B12 can also inspect the front and back sides of the glass product to be inspected respectively.

[0025] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
