Description

Technical Field

[0001] This application relates to the field of electronic component testing technology, and in particular to a line-scan testing device for privacy film products. Background Technology

[0002] The primary function of a computer screen is to protect the LCD screen from scratches. However, with advancements in technology, specialized screen protectors have emerged. For example, gold-plated screen protectors can reduce the impact of radiation on the human body, tinted screen protectors can adjust color temperature to reduce eye strain, and polarized screen protectors can reduce or increase the viewing angle. This has also led to the development of privacy screen protectors, which prevent side viewing and ensure that only users facing the screen can see the content on the computer.

[0003] After the privacy film product is die-cut, its appearance needs to be inspected to determine whether there are scratches, defects or other defects. The existing inspection methods are mostly manual and rely on the naked eye to inspect, and then qualified or unqualified products are separated and recycled. This inspection method is not efficient and of low quality, and undoubtedly increases the labor intensity of operators. Therefore, this application discloses a line scan inspection device for privacy film products. Utility Model Content

[0019] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0020] In the description of this application, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the component or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0021] Example

[0022] To address the problems existing in current technologies regarding the visual inspection of die-cut privacy film products, this paper refers to... Figure 1 and Figure 2 As shown, in some embodiments, this application discloses a line-scanning inspection device for privacy film products, including an inspection machine 10, a first conveyor line 20, a swing wheel sorting table 30, a second conveyor line 40, a third conveyor line 50, and a scanning inspection mechanism 60.

[0023] The first conveyor line 20 is arranged along the first direction on the inspection platform 10 for conveying privacy film products. The swing wheel sorting table 30 is arranged at the end of the first conveyor line 20 for conveying the privacy film products that have been inspected to the first direction or the second direction. The second conveyor line 40 and the third conveyor line 50 are arranged on both sides of the swing wheel sorting table 30 in the first direction and the second direction, respectively for conveying privacy film products that have passed inspection and privacy film products that have failed inspection. The extension line of the second conveyor line 40 in the first direction and the extension line of the third conveyor line 50 in the second direction are perpendicular to each other. The scanning inspection mechanism 60 includes a frame arranged above the rear section of the first conveyor line 20, an XY axis drive unit 61 arranged at the bottom of the frame, and a vision scanning unit 62 connected to the XY axis drive unit 61.

[0024] Based on the above structure, in actual use, the completed privacy film products fall one by one onto the first conveyor line 20. Under the conveying of the first conveyor line 20, they are placed in the detection area. When the XY axis drive unit 61 drives the vision scanning unit 62 to move along the X and Y axes, the vision scanning unit 62 will scan and detect the privacy film products. After the detection is completed, the first conveyor line 20 will convey the privacy film products to the swing wheel sorting table 30. If the product is qualified, the swing wheel sorting table 30 will not change its running direction and will convey the qualified product to the second conveyor line 40. If the product is unqualified, the swing wheel sorting table 30 will change its running direction and convey the unqualified product to the third conveyor line 50.

[0025] Furthermore, in practice, operators can place collection devices at the ends of the second conveyor line 40 and the third conveyor line 50 to collect and process qualified and unqualified products separately.

[0026] Specifically, the XY-axis drive unit 61 of this application includes an X-axis servo module 611, a linear guide rail 612, a Y-axis servo module 613, and a drive base 614. The X-axis servo module 611 and the linear guide rail 612 are respectively disposed at the bottom of two crossbeams in the second direction of the frame. The Y-axis servo module 613 is connected to the bottom of the X-axis servo module 611 and the linear guide rail 612. The drive base 614 is connected to the bottom of the Y-axis servo module 613. During the specific testing process, with the cooperation of the X-axis servo module 611 and the linear guide rail 612, the Y-axis servo module 613 will move along the X-axis direction. Driven by the Y-axis servo module 613, the drive base 614 will move in the Y-axis direction. Furthermore, the X-axis servo module 613 drives the drive base 614 to move in the Y-axis direction. The visual scanning unit 62 is mounted on the drive base 614. The visual scanning unit 62 specifically includes an L-shaped camera base 621, a visual scanning camera 622, and a ring light source 623. The L-shaped camera base 621 is located on one side of the drive base 614, the visual scanning camera 622 is mounted on the L-shaped camera base 621, and the ring light source 623 is fitted around the outer ring of the visual scanning camera 622. While the drive base 614 moves along the X and Y axes, the L-shaped camera base 621 will move along the X and Y axes. During this process, the visual scanning camera 622 will scan the privacy film product along the X and Y axes. With the cooperation of an external control system, it can detect whether there are scratches or defects on the privacy film product.

[0027] In addition, in order to block the privacy film product from the area set by the first conveyor line 20 for testing, this application also includes a lifting blocking mechanism 70. The lifting blocking mechanism 70 includes a blocking door 72 and two rodless cylinders 71. The two rodless cylinders 71 are respectively set on both sides of the frame in the second direction at the conveying end of the first conveyor line 20. The blocking door 72 is connected between the two slides of the two rodless cylinders 71. Before the privacy film is conveyed to the end of the first conveyor line 20, the two rodless cylinders 71 will synchronously drive the lifting door to descend. When the privacy film product is conveyed by the first conveyor line 20 and comes into contact with the lifting door, the subsequent scanning and testing work can begin. In addition, as a preferred embodiment of this application, the blocking door 72 is provided with a rubber stop 73 on the side facing the first conveyor line 20, which can prevent the privacy film product from contacting the lifting door, thereby effectively protecting the privacy film product.
