[0003] At present, the optical film lamination of the cover plate adopts the laser cutting process to replace the traditional film lamination process. The optical film is laminated to the cover plate by expanding 3-4mm according to the shape of the cover plate, and then the shape of the optical film is trimmed by laser cutting so that the outer edge of the optical film and the cover plate are within a fixed distance. This lamination process improves the lamination accuracy of the optical film and the lamination accuracy of the special-shaped film, but there is a risk of poor cutting in laser cutting. Uneven laser cutting leads to glue overflow at the edge, or excessive cutting beyond the range of the cover plate, etc., which will produce defective products. Defective products need to be manually inspected and picked out, affecting production efficiency. Utility Model Content

[0024] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0025] A device for detecting the lamination accuracy of optical films on cover plates, referring to Figure 1 , including a frame 10, on which an assembly line 20 is arranged along the length direction, one end of the assembly line 20 is a feed end 21, and the other end is a discharge end 22. A plurality of cover plate bodies 30 are placed on the assembly line 20, and the plurality of cover plate bodies 30 are evenly distributed along the length of the assembly line 20. The plurality of cover plate bodies 30 are transported from the feed end 21 of the assembly line 20 to the discharge end 22. In this embodiment, the cover plate body 30 is a cover plate bonded with an optical film and subjected to laser cutting.

[0026] Reference Figure 1 and Figure 2 , a detection assembly for detecting the cover body 30 and a bad spraying assembly for spraying defective products are arranged along the length direction of the assembly line 20, and the detection assembly and the bad spraying assembly are arranged in sequence along the direction from the feed end 21 to the discharge end 22 of the assembly line 20. The detection assembly includes a detection box 40 and a CCD detection device 41 arranged in the detection box 40. The detection box 40 is set on the assembly line 20, and an inlet 401 for the cover body 30 to enter is opened on the side of the detection box 40 facing the feed end 21, and an outlet 402 for the cover body 30 to exit is opened on the side of the detection box 40 facing the discharge end 22. The cover body 30 enters the detection box 40 from the inlet 401 of the detection box 40 to be detected and exits from the outlet 402 of the detection box 40.

[0027] Reference Figure 3 and Figure 4The CCD detection device 41 is fixed on the inner top of the detection box 40. The CCD detection device 41 is a camera. The shooting direction of the CCD detection device 41 faces downward and is directly opposite to the surface of the cover body 30. The CCD detection device 41 is used to shoot the cover body 30 entering the detection box 40 to obtain the bonding condition of the optical film on the surface of the cover body 30. The cover body 30 is divided into a good cover body 30 and a defective cover body 30. The CCD detection device 41 determines whether the cover body 30 is a good cover body 30 or a defective cover body 30 according to the shooting result. The good cover body 30 is that the distance between the two outer sides of the optical film on the surface of the cover body 30 and the outer edge of the cover body 30 is within the specified range, while the defective cover body 30 is that the distance between any one outer side of the optical film on the surface of the cover body 30 and the outer edge of the cover body 30 exceeds the specified range, including that the optical film after bonding is too small and the optical film after bonding is too large.

[0028] Further, refer to Figure 2 , a lighting lamp 42 is arranged in the detection box 40, and the lighting direction of the lighting lamp 42 is toward the surface of the assembly line 20. The lighting lamp 42 provides a light source for the detection box 40, so that the CCD detection device 41 has sufficient light when shooting, ensuring that the shooting result is effective. When the assembly line 20 is moving, the CCD detection device 41 and the lighting lamp 42 are both turned on, so that the cover body 30 can be photographed after entering the detection box 40.

[0029] Further, refer to Figure 2 In order to enable the CCD detection device 41 to take pictures immediately after the cover body 30 enters the detection box 40, a sensor 43 is provided in the detection box 40. The sensor 43 is used to sense the entry of the cover body 30. When the sensor 43 senses that the cover body 30 enters the detection box 40, the CCD detection device 41 takes pictures.

[0030] Reference Figure 2 A controller 50 is provided on the detection box 40, and the CCD detection device 41, the irradiation lamp 42 and the sensor 43 in the detection box 40 are electrically connected to the controller 50. When the sensor 43 enters the detection box 40, the controller 50 controls the CCD detection device 41 to take pictures, and the CCD detection device 41 transmits the shooting results to the controller 50, and determines whether the cover body 30 is a defective cover body 30.

[0031] Reference Figure 1 and Figure 2The defective spraying assembly is arranged at one side of the detection assembly. The defective spraying assembly includes a bracket 60 fixed at one side of the frame 10 and a sprayer 61 arranged on the bracket 60. The bracket 60 is fixed at one side of the frame 10. The sprayer 61 is located at the top of the bracket 60. The sprayer 61 is located directly above the assembly line 20. The spraying direction of the sprayer 61 is toward the surface of the assembly line 20. The sprayer 61 is electrically connected to the controller 50. When the cover body 30 enters the detection box 40 and is photographed and judged by the CCD detection device 41, when the cover body 30 is determined to be a defective product, the controller 50 controls the sprayer 61 to spray the defective cover body 30, so as to separate the defective cover body 30 in the subsequent process, and the good cover body 30 continues to be transported to the next process along the length direction of the assembly line 20, thereby replacing the manual full inspection and improving the production efficiency.

[0032] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
