[0002] With the continuous advancement of technology, people have increasingly higher requirements for the performance of electronic products. Existing electronic products, such as mobile phones and tablets, cannot do without the use of glass plates, which can be used to make structures such as LCD screens and light guide plates.

[0003] The quality of the glass plate directly affects the quality of the manufacturing of structures such as LCD screens and light guide plates. Before manufacturing, it is necessary to remove foreign matter residues and scratches from the glass plate surface to ensure the reliability of subsequent processing. In the current technology, foreign matter and scratches are directly detected on the surface of the glass plate manually, which is extremely inefficient and cannot guarantee the quality of the detection.

[0004] Therefore, this application discloses a device for detecting foreign objects and scratches on glass surfaces. Utility Model Content

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0026] In the description of this application, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the component or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Example

[0027] To address the shortcomings of existing technologies that rely on manual inspection of glass plates for foreign objects and scratches; (referencing...) Figures 1-4 As shown, this application provides the following technical solution: a glass surface foreign object and scratch detection device, including a detection machine 10, a dual-station detection mechanism 20 and a sorting and unloading mechanism 30; the detection machine 10 is provided with a first belt conveyor line 40 along a first direction. In actual use, the operator or robot arm 33 places the glass plates to be detected one by one on the first belt conveyor line 40, and under the conveying of the first belt conveyor line 40, each glass plate will move forward;

[0028] The dual-station inspection mechanism 20 includes a first mounting bracket located on one side of the inspection machine 10 corresponding to the middle section of the first belt conveyor 40 and two camera inspection components 22 arranged side by side on the vertical support 21. When the two glass plates are conveyed by the first belt conveyor 40 to the area below the two camera inspection components 22, the two camera inspection components 22 will inspect the two glass plates respectively to determine whether there are foreign objects or scratches on the surface of the two glass plates.

[0029] The sorting and unloading mechanism 30 includes a T-shaped bracket 31 located on the inspection platform 10 along the second direction at the end of the first belt conveyor 40, a telescopic drive unit 32 located on the transverse part of the T-shaped bracket 31 along the second direction, two robotic arms 33 connected to the telescopic drive unit 32, and two second belt conveyors 34 and a third belt conveyor 35 located on the other side of the inspection platform 10 along the first direction. When unloading the inspected glass plates, the telescopic drive unit 32 first drives the two robotic arms 33 to be positioned above the first belt conveyor 40 in sequence and grabs one inspected glass plate in sequence. Then, according to the detection results of the two camera detection components 22, the telescopic drive unit 32 drives the two robotic arms 33 to move above the second belt conveyor 34 or the third belt conveyor 35. Finally, the two robotic arms 33 place the grabbed glass plates on the corresponding belt conveyors.

[0030] To ensure precise movement of the glass plates on the first belt conveyor 40, this application provides several positioning protrusions 41 arranged along a first direction on the first belt conveyor 40. A glass positioning groove is provided above the positioning protrusions 41. In actual use, the operator or robot must place the glass plate to be inspected into the positioning groove. In addition, this application also provides a connecting part 42 integrally on one side of the two positioning protrusions 41. A laser emitter 43 is provided on the outer wall of the connecting part 42. A laser receiver 44 is provided on one side of the middle section of the first belt conveyor 40. Only when the laser emitted by the laser emitter 43 is received by the laser receiver 44 can it be said that the two glass plates to be inspected are accurately located below the two camera detection components 22. At this time, the first belt conveyor 40 will stop running.

[0031] In one specific embodiment, the telescopic drive unit 32 of this application includes a linear guide rail 321 disposed on the side of the transverse portion of the T-shaped bracket 31 facing the first belt conveyor line 40, the second belt conveyor line 34, and the third belt conveyor line 35; a sliding seat 322 slidably disposed on the linear guide rail 321; a linear rack 323 disposed above the sliding seat 322; a servo geared motor 324 disposed on the rear side of the transverse portion of the T-shaped bracket 31 with its output shaft passing through the transverse portion of the T-shaped bracket 31; and a gear 325 mounted on the drive shaft of the servo geared motor 324 and meshing with the linear rack 323. When the two robotic arms 33 move, the servo motor drives the gear 325 to rotate, and with the cooperation of the gear 325 and the linear rack 323, the sliding seat 322 will move telescopically. Based on this embodiment, the robotic arm 33 of this application includes a lifting pneumatic slide 331 provided on the sliding seat 322 and a plurality of pneumatic suction cups 332 provided at the bottom of the lifting pneumatic slide 331. While the sliding seat 322 slides, the two robotic arms 33 located on the sliding seat 322 can slide, and the glass plate can be adsorbed or released by the suction or blowing of the plurality of pneumatic suction cups 332.

[0032] In one specific implementation, the camera inspection component 22 of this application includes a manual fine-tuning module 221 and a visual inspection camera 222 mounted on the manual fine-tuning module 221. Before the visual inspection camera 222 operates, the operator needs to adjust the height of the visual camera through the manual fine-tuning module 221 to place it in a better inspection position. When inspecting the glass plate, the visual inspection camera 222 will take pictures of the glass plate below it and transmit them to the computer system for processing (this part is not protected by this application). In addition, in order to improve the inspection quality of the visual inspection camera 222, this application also provides a light box 23 on the vertical bracket below the two camera inspection components 22. During the inspection process, the light box 23 is lit up, so that the glass plate below the light box 23 is clearer.
