[0018] According to the technical solution of the present invention, without changing the essential spirit of the present invention, those skilled in the art may propose a variety of interchangeable structural methods and implementation methods. Therefore, the following specific embodiments and drawings are merely illustrative of the technical solution of the present invention and should not be regarded as the entire present invention or as a limitation or restriction of the technical solution of the present invention.

[0019] The technical solution of the present utility model is further described in detail below with reference to the accompanying drawings and embodiments.

[0020] Example 1, as Figure 1 and Figure 2 The device, shown in Figure 1, is a device for inspecting the appearance of finished film sheets. It includes a positioning platform 1 and a vision system 2. The positioning platform 1 is made of a transparent material and is used to place films such as mobile phone screen protectors, TV screen protectors, and screen protectors. The vision system 2 is mounted above the positioning platform 1 and uses an internally mounted industrial camera to take photos of the film sheet held in the positioning platform 1. The images are captured and analyzed by a server to determine if the film is qualified.

[0021] The top of the positioning platform 1 is equipped with side bars 11, round bars 12, and pressure bars 13. Two side bars 11 and two round bars 12 are provided, interlaced at right angles. The side bars 11 and round bars 12 are connected to form a rectangular frame. Multiple pressure bars 13 are provided, with their ends fitting over the round bars 12 and adjustable within the rectangular frame. To accommodate diaphragm products of varying sizes, simply adjust the position of the pressure bars 13. By adjusting the distance between adjacent pressure bars 13, diaphragms of varying lengths can be flattened, facilitating image detection by the visual system 2.

[0022] See also Figure 3 and Figure 4As shown, one side of the pressure rod 13 is provided with an avoidance groove 16 along its extension direction. The avoidance groove 16 is a rectangular structure. A movable block fixed to the round rod 12 is provided in the avoidance groove 16. The movable block is a square structure, and its height is consistent with the height of the avoidance groove 16. The movable block is horizontally connected in the avoidance groove 16, so that the distance between the round rod 12 on this side and the round rod 12 on the other side can be adjusted to accommodate diaphragm products of different specifications. The other side of the pressure rod 13 is fitted with the round rod 12 on the other side and is set in a non-movable manner to play a positioning role. The bottom of the pressure rod 13 plays the role of pressing the diaphragm, making it convenient to unfold the diaphragm for appearance inspection.

[0023] More specifically, a pressure block 14 is connected to the bottom of the round rod 12. The bottom surface of the pressure block 14 is arranged horizontally with the positioning platform 1, and the pressure block 14 flattens the edge of the diaphragm. One side of the side rod 11 is fitted with the round rod 12. The other side of the side rod 11 is provided with a waist groove 17 that moves horizontally with the end of the round rod 12. This waist groove 17 facilitates the movement of the round rod 12 and also cooperates with the horizontal movement of the avoidance groove 16 and the movable block. The waist-shaped structure has the function of upper and lower limit, which only allows the round rod 12 to move horizontally and linearly with the pressure block 14.

[0024] As a preferred solution, an auxiliary pressure strip 15 is also installed on one side of the positioning platform 1. Both ends of the auxiliary pressure strip 15 are provided with positioning grooves 18 connected to the positioning platform 1. The positioning groove 18 is a waist-shaped structure. The positioning platform 1 adjusts the distance relative to the positioning platform 1 through the positioning groove 18.

Light panel 32 is positioned below the bottom of positioning platform 1 and is oriented upward. Driven by linear guides 31, positioning platform 1 moves. When it reaches the top of light panel 32, it is illuminated by light panel 32, making it easier to detect appearance defects on the film, which are then captured by vision system 2.

[0026] Columns 23 are mounted on both sides of the top of the stand 3 to support the entire vision system 2. The vision system 2 includes a housing, within which a row of industrial cameras are mounted. The housing's two sides are pivotally connected to the tops of the columns 23 via shafts 21. This allows the industrial cameras to adjust their shooting angles, capturing the diaphragm's appearance from different angles and performing a comprehensive visual inspection of the diaphragm.

[0027] In addition, it should be noted that a cooling fan 24 is provided on the top of the shell to dissipate heat for the industrial camera when it is working. An interface board 25 is provided at the front end of the shell to connect the power and data cables. A row of shooting holes 26 are provided at the bottom of the shell to provide space for shooting with the industrial camera. In order to protect the dust-proof effect, a high-lens lens is also installed.

[0028] For details, please refer to Figure 6 Clamps 22 are provided on both sides of the housing. A rotating shaft 21 is connected to the middle of the clamps 22 and is rotatably arranged with the clamps 22. As a preferred solution, a support frame 27 is provided on the top of the clamps 22. The top of the support frame 27 is a flat structure and can be integrated with the clamps 22. A bracket 28 is fixed to the top of the column 23. The two sides of the bracket 28 contact the top of the support frame 27 via tightening screws 29. By tightening the tightening screws 29, the shooting angle after the rotating shaft 21 is rotated can be fixed. In addition, the angle can be fine-tuned by adjusting the tightening screws 29 on both sides.

[0029] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only a specific implementation method of the utility model and is not intended to limit the scope of protection of the utility model.
