Detailed Description
In order to make the technical solution of the present utility model better understood by those skilled in the art, the technical solution of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present utility model without making any inventive effort, shall fall within the scope of the present utility model.
Example 1
As shown in fig. 1, this embodiment provides a non-contact dust removal and defect detection device for processing cover glass, which comprises a housing 1, wherein two opposite ends of the housing 1 are respectively provided with a feeding port 101 and a discharging port, a transmission channel is arranged between the feeding port 101 and the discharging port in the housing 1, the transmission channel can adopt a transmission roller 3 driven by a motor to rotate, and glass 2 is put into the transmission channel from the feeding port 101 and then is transmitted towards the direction of the discharging port.
As shown in fig. 2-3, the transmission channel is divided into a first transmission area 301 and a second transmission area 302 along the transmission direction of the glass 2, and the size of each of the first transmission area 301 and the second transmission area 302 is not smaller than that of a whole glass 2; an electrostatic removing mechanism (such as an ion fan 7) is arranged in the shell 1 and positioned at the first transmission area 301, ion wind is blown to the surface of the glass 2, static electricity of dust and foreign matters on the surface of the glass 2 is removed, electrostatic adsorption force between the dust and foreign matters and the surface of the glass 2 is lost, and subsequent dust removal is facilitated. The green laser 4, the exhaust fan 5 and the glass quality vision detection system 6 (a ken vision CCD camera, CA-H500M CA-H500C) are arranged at the second transmission area 302, and since the green light irradiates the surface of the glass 2 more easily to make the dust on the surface appear, the green laser 4 is obliquely arranged in the housing 1, and the emitted green laser is obliquely irradiated on the surface of the glass 2 at a certain angle. The smooth surface of the glass 2 will generate less diffuse reflection light, while dust and foreign matters will diffuse reflect more light, so that the dust and foreign matters can be found more easily, and the phenomena such as cracks and bubbles inside the glass 2 will also generate diffuse reflection after being irradiated, and finally, the diffuse reflection light will be collected and shot by the glass quality visual detection system 6 for dust, foreign matters and defect analysis.
Working principle:
the glass 2 is put on the inner conveying roller 3 through the feeding port 101 of the device, and is conveyed forward under the drive of the conveying roller 3. In the process of conveying the glass 2, the glass firstly enters the first conveying area 301, and ion wind is blown to the surface of the glass 2 through the ion fan 7, so that static electricity of dust and foreign matters on the surface of the glass 2 is eliminated, electrostatic adsorption force between the dust and foreign matters and the surface of the glass 2 is lost, and subsequent dust removal is facilitated. And then enters the second transfer zone 302 by the transfer roller 3 and stays in this zone. The suction fan 5 sucks air, and sucks dust and foreign matters on the surface of the glass 2 through the suction opening in the housing 1.
Meanwhile, the green laser 4 emits green laser to the surface of the glass 2, the glass 2 and the dust and foreign matter on the surface reflect light rays, the glass quality vision detection system 6 collects and shoots dust and foreign matter on the surface of the glass, if the glass quality vision detection system 6 detects that the surface has a reflection point generated by dust and foreign matter, the reflection point is transmitted to the PLC 10 through an electric signal, the PLC 10 continues to start the exhaust fan 5, so that dust removal is always performed, as shown in fig. 1, an indicator lamp 9 can be arranged outside the shell 1, and the indicator lamp 9 displays red when the dust removal is performed, so that the surface of the glass 2 detects dust and foreign matter; until the glass quality vision detection system 6 can not shoot dust and foreign matters on the surface of the glass 2, the PLC controller 10 turns off the exhaust fan 5 again to stop dust removal, and the indicator lamp 9 turns green at the moment to indicate that the surface of the glass 2 is free of dust and foreign matters.
In addition, if the glass quality visual inspection system 6 detects that the surface of the glass 2 has abnormal reflection points and is not cleaned, and the indicator lamp 9 always displays red, bubbles and cracks inside the glass 2 may be caused. Therefore, the detection time length can be preset in the PLC 10, when the indicator lamp 9 always displays red color and the detection time length exceeds the preset detection time length, the PLC control system turns off the exhaust fan 5, stops dust removal, and starts the transmission roller 3 again to transmit the glass 2 to the discharge opening for taking out; and meanwhile, the photo with the abnormal reflecting point is transmitted to a central control display screen, and the position of the abnormal reflecting point is displayed to a worker, so that the defect of the glass 2 is found.
Example 2
On the basis of embodiment 1, as shown in fig. 2-3, four ultrasonic generators 8 are further disposed at the second transmission region 302, and are respectively disposed at four corners of the second transmission region 302. After the glass 2 is transferred to the second transfer area 302 and stays, the ultrasonic generator 8 is started to emit ultrasonic waves to the glass 2, so that the glass 2 vibrates, and dust and foreign matters on the surface of the glass 2 are removed under the cooperation of the exhaust fan 5.
Although the present utility model has been described in detail by way of preferred embodiments with reference to the accompanying drawings, the present utility model is not limited thereto. Various equivalent modifications and substitutions may be made in the embodiments of the present utility model by those skilled in the art without departing from the spirit and scope of the present utility model, and it is intended that all such modifications and substitutions be within the scope of the present utility model/be within the scope of the present utility model as defined by the appended claims. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
