[0034] The present invention will be further described in detail below with reference to the accompanying drawings.

[0035] like Figure 1 、 Figure 2 、 Figure 4 The film inspection device shown includes a frame 100, a camera assembly 200, a light source assembly 300, and an inspection station 500 for supporting a film 600. The frame 100 is provided with a first sliding portion 101 and a second sliding portion 102 for slidingly connecting to other components. The sliding paths of the first sliding portion 101 and the second sliding portion 102 are both arc-shaped, meaning that components provided on the first sliding portion 101 and the second sliding portion 102 can move relative to the frame 100 along the arc-shaped paths. The camera assembly 200 is used to photograph and inspect the film 600 and is slidably connected to the first sliding portion 101. The light source assembly 300 is used to illuminate the surface of the film 600 and is slidably connected to the second sliding portion 102. The camera assembly 200 has a photographing port 03 through which the camera assembly 200 photographs and inspects the film 600. The light source assembly 300 has an illumination port 04 through which light emitted by the light source assembly 300 is emitted to illuminate the film 600. The detection position 500 is arranged in a direction relative to the shooting port 03 and the illumination port 04. It is understood that in order to ensure that the shooting port 03 and the illumination port 04 can always face the detection position 500, the centers of the arc motion paths of the camera assembly 200 and the light source assembly 300 coincide with each other, and the detection position 500 is arranged at the center of the arc motion paths of the camera assembly 200 and the light source assembly 300.

[0036] Through the above design, when the camera assembly 200 and the light source assembly 300 perform circular motion along the first sliding portion 101 and the second sliding portion 102 respectively, since the motion path is circular and the detection position 500 is located at the center of the motion path of the camera assembly 200 and the light source assembly 300, during the motion process, the shooting port 03 of the camera assembly 200 and the irradiation port 04 of the light source assembly 300 can always remain facing the direction where the detection position 500 is located. The shooting angle of the camera assembly 200 relative to the detection position 500 and the irradiation angle of the light source assembly 300 relative to the detection position 500 will gradually change. In actual use, by making the camera assembly 200 and the light source assembly 300 perform circular motion with the detection position 500 as the center, the camera assembly 200 and the light source assembly 300 can be adjusted to the appropriate shooting angle and irradiation angle respectively; the sliding angle adjustment method is simple in structure and more accurate than the rotation angle adjustment method. It also does not require the use of high-precision motor equipment, and is simple and convenient to adjust.

[0037] The following will introduce the technical details of each component one by one.

[0038] In some embodiments, as Figure 4As shown, the camera assembly 200 includes a slide rail 21, a slider 22 and a shooting member 23. The slide rail 21 is slidably connected to the first sliding portion 101, the slider 22 is slidably connected to the slide rail 21, and the shooting member 23 is connected to the slider 22. The shooting member 23 can slide along the slide rail 21 following the slider 22.

[0039] For ease of description, Figure 4 、 Figure 5 、 Figure 6 As shown, the moving direction of the film 600 at the detection position 500 is set as the X direction, the width direction of the film 600 is set as the Y direction, and the X direction is perpendicular to the Y direction.

[0040] like Figure 4 、 Figure 5 As shown, the slide rail 21 extends along the Y direction. With this design, the camera 23 can move along the width of the film 600. In practical applications, the film 600 to be inspected is typically in a rolled form. During inspection, the film 600 is secured to a roller and gradually unrolled. As it passes through the inspection position 500, the camera 23 continuously photographs and inspects the film 600 at the inspection position 500, thereby inspecting the entire roll of film 600. It will be appreciated that to ensure that the camera 23 can inspect the entire surface of the film 600, the camera's inspection range in the width direction (i.e., the Y direction) of the film 600 must be greater than the width of the film 600. With this design, the camera 23 can slide along the width direction (i.e., the Y direction) of the film 600. By conveniently adjusting the position of the camera 23, the camera's inspection range can completely cover the film 600 in the width direction (i.e., the Y direction), thereby ensuring comprehensive inspection of the film 600.

[0041] In some embodiments, as Figure 4 、 Figure 5 As shown, the slide rail 21 is slidably connected to at least two sliders 22. This design allows for the installation of multiple imaging elements 23, each of which can slide along the slide rail 21. In practical applications, when the width of the film 600 to be inspected is excessively wide, to ensure comprehensive inspection of the film 600, multiple imaging elements 23 are required to capture the entire film 600, ensuring that the combined imaging range of all imaging elements 23 completely covers the film 600 in the width direction (i.e., the Y direction). The fact that multiple imaging elements 23 can slide along the slide rail 21 also facilitates adjustment of the spacing between the individual imaging elements 23 to ensure comprehensive imaging and inspection of the film 600 surface.

[0042] In some embodiments, as Figure 4 、 Figure 5As shown, the camera assembly 200 further includes an adjustment base 24 for adjusting the orientation of the photographing port 03. The adjustment base 24 is disposed between the slider 22 and the photographing element 23. Typically, the adjustment base 24 is a three-axis adjustment base 24. Once the photographing element 23 is mounted on the adjustment base 24, it can be rotated in any direction, facilitating fine-tuning of the photographing angle of the photographing element 23.

[0043] In actual use, the shooting component 23 can be a device with a camera function. Depending on the different detection requirements, the model and size of the selected shooting component 23 will also be different. The orientation of the shooting port 03 of different models of shooting components 23 will be different, so the shooting angle of the shooting component 23 can be adjusted through the adjustment seat 24 to ensure that the shooting port 03 of the shooting component 23 can be aligned with the detection position 500.

[0044] In some embodiments, as Figure 4 、 Figure 5 、 Figure 6 As shown, the camera assembly 200 further includes a locking member 25 for locking the position of the slide rail 21. The locking member 25 is connected to the slide rail 21 and moves with it. Accordingly, the frame 100 is provided with a locking portion 103, to which the locking member 25 is detachably connected. The connection between the locking member 25 and the locking portion 103 prevents the slide rail 21 from sliding relative to the frame 100. Once the camera 23 moves to a desired shooting angle following the slide rail 21, the locking member 25 locks the shooting angle. In practice, the camera 23 is protected from vibrations and other factors affecting the desired shooting angle, thereby improving the suitability and stability of the shooting angle during the film 600 inspection process.

[0045] For details, please refer to Figure 4 、 Figure 5 、 Figure 6As shown, the frame 100 includes two side panels 12, which are arranged opposite each other. A slide rail 21 is disposed between the two side panels 12, and the ends of the slide rail 21 are slidably connected to the two side panels 12. The slide rail 21 extends perpendicular to the side surfaces of the side panels 12, and the slide path of the slide rail 21 is arc-shaped. One end of the locking member 25 is connected to the end of the slide rail 21, and the other end extends near the side panel 12 and is disposed opposite the side panel 12. The end of the locking member 25 near the side panel 12 is provided with a first locking hole 05. The side panels 12 are evenly spaced apart with a plurality of second locking holes 06, which are arranged along the projection of the first locking holes 05 on the side surfaces of the side panels 12 (i.e., the first locking holes 05 are always aligned with the second locking holes 06 in the Y direction during movement). Bolts are provided between the locking member 25 and the frame 100, and the locking member 25 and the frame 100 are removably connected by the bolts passing through the first locking holes 05 and the second locking holes 06. The above locking method has a simple and effective structure and is also very convenient and fast to operate.

[0046] To ensure effective alignment of the first locking hole 05 and the second locking hole 06, refer to Figure 6 It is understood that the first locking hole 05 extends a predetermined length along its movable path. With the above design, the first locking hole 05 can be moved to any position and aligned with at least one second locking hole 06, thereby locking the camera 23 at any angle within its movable range.

[0047] In some embodiments, as Figure 4 、 Figure 5 、 Figure 6 As shown, the frame 100 is provided with a first arc-shaped hole 01, and the slide rail 21 is provided with a first bolt shaft 211. The first bolt shaft 211 is fixed to the first arc-shaped hole 01 and can slide along the first arc-shaped hole 01. The extension direction of the slide rail 21 is perpendicular to the plane in which the first arc-shaped hole 01 is located. The center of the first arc-shaped hole 01 coincides with the detection position 500, and the shooting port 03 is arranged toward the detection position 500. The first arc-shaped hole 01 is arc-shaped. As the first bolt shaft 211 slides along the first arc-shaped hole 01, it can drive the slide rail 21 and the shooting member 23 to perform an arc motion. The above design structure is simple and does not require complex mechanical structures. When the shooting angle of the shooting member 23 needs to be adjusted, it is only necessary to slide the first bolt shaft 211 along the first arc-shaped hole 01. The operation is simple and requires little experience from the staff.

[0048] It is understandable that the diameter of the first bolt shaft 211 is consistent with the width of the first arc-shaped hole 01, which can reduce the shaking of the camera assembly 200 when performing circular motion.

[0049] In some embodiments, as Figure 4 、 Figure 5As shown, the film detection device provided in the present application also includes a driving mechanism 400 for driving the camera assembly 200 to slide along the first sliding portion 101. The driving mechanism 400 is connected to the frame 100. The driving mechanism 400 has a driving end 401, and the driving end 401 is connected to the first bolt shaft 211 to drive the first bolt shaft 211 to slide along the first arc-shaped hole 01.

[0050] In some other embodiments, such as Figure 2 、 Figure 3 As shown, the drive mechanism 400 includes a drive rail 41, a drive block 42, and a screw mechanism 43. Both the drive rail 41 and the screw mechanism 43 are fixed to the frame 100. The drive block 42 is slidably connected to the drive rail 41, and the screw mechanism 43 is connected to the drive block 42. The screw mechanism 43 is used to drive the drive block 42 to slide along the drive rail 41. The drive block 42 includes a sliding portion 421 and a driving portion 422 that are interconnected. The sliding portion 421 is slidably connected to the drive rail 41. The driving portion 422 defines an oblong hole 07. The driving portion 422 is sleeved with the first bolt shaft 211 through the oblong hole 07, and the first bolt shaft 211 can slide along the oblong hole 07. When the screw mechanism 43 drives the drive block 42 to move along the drive rail 41, the first bolt shaft 211, pushed by the driving portion 422, slides along the second arcuate hole 02. The oblong hole 07 prevents the first bolt shaft 211 from becoming stuck with the drive block 42 when the drive block 42 pushes the first bolt shaft 211. The screw mechanism 43 is very common in practical applications. By using this structure in the thin film inspection device of this application, the camera assembly 200's shooting angle can be adjusted, making operation very convenient.

[0051] In some embodiments, as Figure 2 As shown, the frame 100 is formed with at least one crossbeam 11 along the Y direction. The crossbeam 11 includes a main body 111 and a clamping member 112 for mounting the light source assembly 300. The clamping member 112 is detachably connected to the main body 111. The clamping member 112 can be mounted at any position on the main body 111 along the Y direction to facilitate adjustment of the position of the light source assembly 300 and ensure the lighting effect of the light source assembly 300 on the film 600. In actual use, the position of the light source assembly 300 needs to be adjusted for films 600 of different widths to ensure that the light source assembly 300 can fully illuminate the surface of the film 600 in the Y direction, ensuring that the camera assembly 200 can clearly and completely capture and inspect the surface of the film 600.

[0052] like Figure 2 、 Figure 3As shown, the locking member 112 defines a second arcuate hole 02, and the light source assembly 300 is provided with a second bolt shaft (not shown). The second bolt shaft is locked in the second arcuate hole 02 and can slide along the second arcuate hole 02. The center of the second arcuate hole 02 coincides with the detection position 500, and the illumination port 04 is positioned toward the detection position 500. This design is simple in structure and lacks complex mechanical structures. When the illumination angle of the light source assembly 300 needs to be adjusted, the second bolt shaft can be simply slid along the second arcuate hole 02. This is simple to operate and requires minimal operator experience.

[0053] In some embodiments, as Figure 6 As shown, the light source assembly 300 is used to emit light obliquely toward the surface of the film 600. During actual inspection, it is necessary to detect possible defects such as bumps and dents on the surface of the film 600. By emitting light obliquely toward the surface of the film 600, these defects can be more clearly revealed, thereby facilitating recording by the camera assembly 200.

[0054] In addition to the above technical effects, please refer to Figure 6 It is understood that emitting light obliquely to the surface of the film 600 can also make the illuminated part of the film 600 appropriately away from the light source assembly 300, thereby avoiding the structure of the light source assembly 300 itself from blocking and interfering with the illuminated part of the film 600, which is beneficial to improving the detection accuracy of the camera assembly 200.

[0055] The present application provides a thin film detection method, which uses the above-mentioned thin film detection device and includes:

[0056] Unfold the film 600 to be inspected and place it in the inspection position 500. Adjust the position of the camera assembly 200 along the first sliding portion 101. Since the sliding path of the first sliding portion 101 is an arc, the camera assembly 200's shooting angle will deflect when sliding along the path of the first sliding portion 101. Then, adjust the shooting angle of the camera assembly 200 to achieve the optimal shooting angle for inspecting and photographing the film 600.

[0057] The position of the light source assembly 300 is adjusted along the second sliding portion 102. Since the sliding path of the second sliding portion 102 is arc-shaped, the illumination angle of the light source assembly 300 will be deflected when it slides along the path of the second sliding portion 102, and then the illumination angle of the light source assembly 300 is adjusted to achieve the optimal illumination angle to illuminate the surface of the film 600.

[0058] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0059] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply the existence of any such actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or device comprising the element.

[0060] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
