[0023] In order to better understand and explain the present application, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0024] Please refer to Figure 1-Figure 5 , This embodiment is a film sticking precision detection machine, including a transparent precision mark plate 1 and a recognition camera 2 placed above the precision mark plate 1;

[0025] The precision mark plate 1 is placed on the support structure 3; a shielding layer 6 corresponding to the position of the film strip 5 on the cover plate 4 to be detected is arranged on the precision mark plate 1, and the width of the shielding layer 6 is set to be larger than the width of the film strip 5 on the cover plate 4 to be detected, so that the projection of the shielding layer 6 can completely cover the film strip 5 on the cover plate 4 to be detected, but it cannot be too wide to affect the accuracy. The cover plate 4 to be detected can be glass. Preferably, the width of the shielding layer 6 is 1-2mm wider than the film strip 5 on the cover plate 4 to be detected, and the shielding layer 6 is opaque; the shielding layer 6 is arranged in a grid shape and is attached to the precision mark plate 1 at a predetermined position designed according to the drawing. Along the irradiation direction of the recognition camera 2, the projection of the shielding layer 6 completely covers the film strip 5 on the cover plate 4 to be detected;

[0026] The support structure 3 is also provided with a correction manipulator 7;

[0027] A conveying device 8 is provided below the precision standard plate 1 .

[0028] The film sticking precision detection machine provided in this embodiment is used as follows: Figure 5 As shown, first prepare the precision standard plate 1 according to the glass film drawing, that is, according to the drawing, paste the shielding layer 6 at the same position of the precision standard plate 1 with the same size and shape as the glass. Then put the precision standard plate 1 on the support rod 31. Start the film laminating machine, and after the glass is filmed, it is transferred to the bottom of the precision standard plate 1 through the conveyor belt. The positioning manipulator corrects the glass and the precision standard plate 1 so that the glass and the precision standard plate 1 overlap. The camera takes a picture and identifies it. If it is normal, the conveyor belt will run and the glass will be released. If it is abnormal, the glass film belt 5 exceeds the shielding range of the shielding layer 6 on the precision standard plate 1, then the glass is unqualified and needs to be repaired. If a batch of glass is unqualified, the film laminating machine will be stopped.

[0029] This application, 1. It is completely inspected by machinery, and can quickly check the accuracy of the film tape 5 during the production process, reducing labor costs. 2. It can quickly check for defective glass, reduce the tangent time of the production line, and improve the quality of component products and the production efficiency of the production line; 3. It can reduce the cost of component downgrade when the film accuracy is poor in batches.

[0030] In this embodiment, optionally, according to another aspect of the present application, the shielding layer 6 includes a laminated adhesive film layer 61 and a spray paint coating 62, and the spray paint coating 62 is black and non-reflective.

[0031] With this arrangement, when the camera takes a picture, it can be more clearly displayed whether the glass film tape 5 is pasted accurately, and the image is clearer.

[0032] In this embodiment, if Figure 2 and Figure 3 As shown in FIG. , optionally, the shielding layer 6 is 2 mm wider than the film strip 5 on the cover plate 4 to be detected.

[0033] In this way, the shielding layer 6 can completely cover the film strip 5 on the glass, and at the same time, the width is not too wide, resulting in a large position deviation of the film strip 5.

[0034] In this embodiment, optionally, the correction manipulator 7 includes a multi-degree-of-freedom manipulator, and an L-shaped correction block is provided at the operating end of the manipulator.

[0035] The L-shaped correction block can push the corner of the glass to facilitate the correction of the glass. The multi-degree-of-freedom robot arm can correct the glass more flexibly.

[0036] Two groups of manipulators can be provided, which are respectively provided at opposite vertex angles, so as to facilitate the movement and correction of the glass and the precision standard plate 1 .

[0037] In this embodiment, optionally, the support structure 3 includes a support frame, at least two support rods 31 are arranged in the middle of the support frame, rollers are arranged above the support rods 31, and the precision standard plate 1 is placed on the rollers.

[0038] The support rod 31 and the roller support the precision mark plate 1, which is convenient for loading and unloading, and will not block the glass too much. Preferably, the support rod 31 and the roller can be set to transparent materials, preferably acrylic high transparent plastic, and the precision mark plate 1 can also use this material

[0039] In this embodiment, the conveying device can be optionally a belt transmission. Belt transmission is a common conveying device in glass transmission, which is stable and not easy to damage the glass. The conveying device can also be a roller transmission, which is more conducive to the support and positioning of the glass.

[0040] The scope of application of the present application is not limited to the processes, mechanisms, manufactures, material compositions and means of the specific embodiments described in the specification. From the disclosure of the present application, it will be easily understood by those skilled in the art that the processes, mechanisms, manufactures, material compositions and means that currently exist or are to be developed in the future, where they perform substantially the same functions as the corresponding embodiments described in the present application or obtain substantially the same results, can be applied to them in accordance with the present application.
