Description

Technical Field

[0001] The utility model relates to the technical field of toughened film appearance detection, in particular to a toughened film appearance detection device. Background Art

[0002] The main function of a mobile phone tempered film is to protect the phone screen from scratches, impacts, and other damage. If the film is deformed, warped, or bubbling, it may cause the film to poorly adhere to the phone screen, thus affecting its protective effect. Therefore, the tempered film is inspected for appearance before leaving the factory to detect and solve these problems in a timely manner.

[0003] Traditionally, the appearance inspection of tempered glass is mainly carried out through manual visual inspection. Workers use tools such as magnifying glasses or microscopes to carefully observe the surface and edges of the film to find possible defects. However, the inspection results are greatly affected by the workers' experience and vision, which may lead to misjudgment or missed inspections, making it difficult to ensure product quality.

[0025] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0026] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] See also Figures 1 to 5 , which is a tempered film appearance inspection device of an embodiment of the utility model, includes a feeder assembly 10, a detection assembly 20 installed on one side of the feeder assembly 10, and a loading and unloading robot 30 installed on the other side of the feeder assembly; the loading and unloading robot 30 is used for loading and unloading operations of the tempered film.

[0029] The material setting component 10 includes a material setting table 11, a limit block 12 movably installed at a corner of the top surface of the material setting table 11, and a telescopic cylinder 13 installed inside the material setting table 11; the telescopic cylinder 13 is used to connect the limit block 12 so that the position of the limit block 12 can be adjusted to adapt to tempered films of different sizes.

[0030] Specifically, Figure 3 and Figure 4As shown, a plurality of air holes 111 are evenly spaced in the middle of the material setting table 11, and an air extraction plate 112 is installed inside the material setting table 11. The air extraction plate 112 matches and connects the air holes 111, and the air extraction plate 112 is connected to a vacuum pump. When the tempered film is placed on the top surface of the material setting table 11, the vacuum pump extracts the air between the tempered film and the top surface of the material setting table 11 through the air extraction plate 112 and the air holes 111, so that the tempered film is tightly attached to the top surface of the material setting table 11.

[0031] The detection assembly 20 includes a column 21 installed on one side of the material setting platform 11, a first longitudinal linear module 22 installed on the top of the column 21, a transverse linear module 23 connected to the first longitudinal linear module 22, a carrier plate 24 connected to the transverse linear module 23, a line spectrum confocal sensor 25 installed on one side of the carrier plate 24, a second longitudinal linear module 26 installed on the other side of the carrier plate 24, an industrial camera 27 connected to the second longitudinal linear module 26, a zoom lens 28 coaxially connected to the industrial camera 27, and a coaxial light source 29 coaxially connected to the end of the zoom lens 28. The industrial camera 27 and the line spectrum confocal sensor 25 are arranged side by side, and both the industrial camera 27 and the line spectrum confocal sensor 25 are located above the material setting platform 11 to detect the appearance of the tempered film.

[0032] The axis of the line spectrum confocal sensor 25 is perpendicular to the top surface of the material table 11 , and the axis of the industrial camera 27 is perpendicular to the top surface of the material table 11 .

[0033] In actual detection, the industrial camera 27 can capture high-resolution images of the tempered film. Through high-quality images, various features on the surface of the tempered film, such as scratches, bubbles, foreign matter, etc., can be clearly identified. The line spectrum confocal sensor 25 can accurately measure the height information of each point on the surface of the tempered film. Combined with the height information, the line spectrum confocal sensor 25 can detect tiny defects on the surface of the tempered film, such as unevenness, deformation, etc. These defects may not be easily found by the naked eye or the industrial camera 27, but the line spectrum confocal sensor 25 can accurately identify them with its high-precision measurement capability, greatly improving the detection efficiency and detection quality. Therefore, by jointly detecting the surface of the tempered film with the industrial camera 27 and the line spectrum confocal sensor 25, the detection accuracy can be significantly improved.

[0034] In this embodiment, the line spectrum confocal sensor 25 is connected to the carrier plate 24 via a manually adjustable slide 250 to adjust the position of the line spectrum confocal sensor 25. The adjustment direction of the manually adjustable slide 250 is perpendicular to the surface of the carrier plate 24 to drive the line spectrum confocal sensor 25 to approach or move away from the surface of the carrier plate 24, which can flexibly adapt to the detection requirements of tempered films of different sizes.

[0035] The loading and unloading robot 30 is located on one side of the material positioning table 11. A suction cup 31 is installed at the end of the loading and unloading robot 30. The suction cup 31 is used to suck the tempered film to place the tempered film on the material positioning table 11 or remove the tempered film from the positioning table 11 to realize the loading and unloading operation of the tempered film.

[0036] The above-mentioned tempered film appearance inspection equipment has a simple structure and is easy to use. It uses the material setting table 11 to position the tempered film, and uses the industrial camera 27 and the line spectrum confocal sensor 25 to jointly detect the surface of the tempered film, replacing the traditional manual visual inspection, effectively preventing misjudgment or missed detection, and greatly improving the detection efficiency and quality.

[0037] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] 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.
