Description

Technical Field

[0001] The utility model relates to the technical field of display screens, and in particular to a fitting detection system for an anti-peep and anti-reflection optical film. Background Art

[0002] Existing cover glass often has an anti-reflection or anti-peep optical film attached to it as needed. In order to ensure the quality of shipment, it is necessary to check whether the finished cover formed after the bonding process has the optical film attached well, and whether the optical film is attached in reverse (i.e., whether the anti-peep direction of the optical film is reversed). Traditionally, the efficiency of observing whether the optical film is attached is low by looking with the naked eye. In addition, the optical film is thin and transparent, and it is difficult to distinguish with the naked eye, resulting in a high overall misjudgment rate. In addition, the inspection of whether the direction of the optical film is attached in reverse is also done manually, which also has the disadvantages of low efficiency and high overall misjudgment rate.

[0038] See also Figure 1 , the embodiment of the utility model provides a fitting detection system for an anti-peep and anti-reflection optical film, comprising: a cover plate to be detected 100, a first detection device 200, a second detection device 300 and a conveyor belt 400;

[0039] The first detection device 200 is used to detect whether the optical film is attached to the cover plate 100 to be detected;

[0040] The second detection device 300 is used to detect whether the optical film on the cover plate 100 to be detected is pasted upside down;

[0041] The conveyor belt 400 is used to convey the cover plate 100 to be inspected to the first inspection device 200 and the second inspection device 300 in sequence.

[0042] Through the technical solution of the embodiment of the utility model, the first detection device and the second detection device can respectively detect whether the cover plate is in contact with the optical film and whether the optical film is pasted upside down, thereby improving the automation of detection, reducing misjudgment and inefficiency caused by manual inspection, reducing production losses and improving production efficiency.

[0043] As a preferred embodiment of the present invention, please refer to Figure 1-2 , the first detection device 200 includes an illuminating lamp 210, a light brightness sensor 220 and a reflectivity calculation module;

[0044] The illumination lamp 210 is disposed above the cover plate 100 to be inspected, and is used to emit light to the cover plate 100 to be inspected;

[0045] The light brightness sensor 220 is disposed above the cover plate 100 to be detected, and is used to receive the reflected light of the cover plate 100 to be detected;

[0046] The reflectivity calculation module is electrically connected to the illuminating lamp 210 and the light brightness sensor, and is used to calculate the reflectivity of the cover plate surface 100 to be detected according to the emitted light of the illuminating lamp 210 and the reflected light received by the light brightness sensor. The reflectivity calculation module can be integrated inside the light brightness sensor, and the system in the utility model can also include a control device, and the reflectivity calculation module can also be separately set in the control device.

[0047] As a preferred embodiment of the utility model, it is characterized in that:

[0048] When the reflectivity is between 4% and 5%, it is considered that the optical film is not attached to the cover plate 100 to be inspected;

[0049] When the reflectivity is between 0% and 2%, it is considered that the optical film has been attached to the cover plate 100 to be inspected.

[0050] In the embodiment of the utility model, for the surface of the commonly used 3mm colorless glass (including automotive glass), the single-sided reflectivity of visible light is in the range of 4% to 5%. When an anti-reflective optical film is attached, the single-sided reflectivity of visible light will be less than 2%. Therefore, it can be set that when the reflectivity is 4% to 5%, it is considered that the optical film is not attached to the cover to be inspected; when the reflectivity is 0% to 2%, it is considered that the optical film is attached to the cover to be inspected. In addition, when the reflectivity is between 2% and 3% or exceeds 5%, it is an abnormal situation, such as a problem with the incoming optical film or a problem with the detection device, etc. At this time, the system will automatically alarm and ask the operator to take it away for re-inspection.

[0051] As a preferred embodiment of the present invention, please refer to Figure 2 , the anti-peep and anti-reflection optical film fitting detection system further includes a first suction device 500 and a first isolation area;

[0052] The first suction device 500 is disposed above the cover plate 100 to be inspected, and is used to suction the cover plate 100 to be inspected and move the cover plate 100 to the first isolation area when it is detected that the optical film is not attached to the cover plate 100 to be inspected.

[0053] The first suction device 500 is disposed between the first detection device 200 and the second detection device 300 . When the first detection device 200 is used to detect that the optical film is correctly attached to the cover plate 100 to be detected, the first suction device 500 is skipped and directly transmitted to the second detection device 300 .

[0054] As a preferred embodiment of the present invention, the first suction device 500 includes a telescopic mechanical arm 510 and a suction nozzle 520. The suction nozzle 520 is connected to the telescopic mechanical arm 510 and performs a vacuum operation when started to suck the cover plate to be inspected without film.

[0055] The first isolation zone is not shown in the figure, and the first isolation zone can be set outside the conveyor belt. The cover plates to be inspected without film will be flexibly transferred to the first isolation zone by the telescopic robot arm 510. After the system is shut down, the operator will uniformly recycle the cover plates in the first isolation zone.

[0056] As a preferred embodiment of the present invention, please refer to Figure 1-3 , the second detection device 300 includes a backlight module 310 and a high-definition camera 320;

[0057] The backlight module 310 is disposed inside the conveyor belt 400 . During detection, the backlight module 310 simulates the display to emit light and illuminates the cover plate 100 to be detected below the cover plate 100 to be detected.

[0058] The high-definition camera 320 is disposed in the upper front of the cover plate 100 to be inspected, and is used to identify the color of the view of the illuminated cover plate 100 to be inspected;

[0059] If the image color is white, the optical film on the cover plate 100 to be inspected is not reversed;

[0060] If the view color is gray, the optical film on the cover plate 100 to be inspected is pasted upside down.

[0061] In the present invention, the anti-peep and anti-reflection optical film is one-way anti-peep. When viewed from the side on both sides, the white light emitted by the backlight module can be normally seen when viewed from the side on one side, and only gray light can be seen when viewed from the side on the other side because it is blocked by the unilateral anti-peep layer of the optical film. Therefore, the colors of the views seen from the two sides are different, so it can be determined whether the optical film is pasted upside down. That is, the high-definition camera 320 is placed in the upper front, and when the cover plate 100 to be detected passes above the backlight module 310, the high-definition camera 320 will simulate the perspective of a bystander to shoot from the side, upper front, and if the color of the view captured is white, the optical film on the cover plate 100 to be detected is not pasted upside down; if the color of the view is gray, the optical film on the cover plate 100 to be detected is pasted upside down.

[0062] The conveyor belt may be a transparent conveyor belt, so that when the backlight module emits light inside the conveyor belt, it illuminates the cover plate to be detected. Alternatively, the conveyor belt has an opening, and the size of the opening only needs to ensure that the cover plate to be detected can be placed on the conveyor belt without falling into the opening. When the cover plate to be detected reaches the backlight module, the light emitted by the backlight module will pass through the opening and irradiate the cover plate to be detected.

[0063] As a preferred embodiment of the present invention, the anti-peep and anti-reflection optical film lamination detection system further includes an alarm device, which is used to send an alarm signal when the optical film is not lamination on the cover plate to be detected, or when the optical film on the cover plate to be detected is lamination upside down. The alarm device can also send an alarm message to the client, etc., to notify the operator to remove the cover plate with the optical film lamination upside down for repair.

[0064] As a preferred embodiment of the present invention, the alarm device includes a signal light, and its alarm signal can be a flashing red light.

[0065] As a preferred embodiment of the present invention, the alarm device includes a buzzer, and its alarm signal can be a buzzer sound.

[0066] As a preferred embodiment of the present invention, please refer to Figure 2 , the anti-peep and anti-reflection optical film fitting detection system further includes a second suction device 600 and a second isolation area;

[0067] The second suction device 600 is disposed above the cover plate 100 to be inspected, and is used to suck the cover plate to be inspected and move the cover plate 100 to the second isolation area when it is detected that the optical film on the cover plate to be inspected is pasted upside down.

[0068] Among them, the second suction device 600 is arranged after the second inspection device 300. When the optical film is not pasted upside down, the second suction device 600 will be skipped for shipment; the cover plate to be inspected with the optical film pasted upside down will be flexibly transferred to the second isolation area by the second suction device 600, and the operator will perform unified repair of the cover plates in the second isolation area after the system is shut down.

[0069] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
