[0003] The prior art provides a device for detecting the uniformity of conductive coating on aluminum foil (publication number CN212791669U), comprising an unwinding device, a first coating machine, a first drying oven, a second coating machine, a second drying oven, and a winding device arranged sequentially along the conveyor belt direction; the unwinding device, the first coating machine, the first drying oven, the second coating machine, the second drying oven, and the winding device are all connected to a control device; a first grayscale meter for detecting one side of the foil is provided between the first drying oven and the second coating machine; a second grayscale meter for detecting the other side of the foil is provided between the second drying oven and the winding device; both the first and second grayscale meters are connected to a host computer; the host computer and the control device communicate bidirectionally.
[0004] In practical use, the aforementioned patent employs a grayscale meter to conduct online detection of the aluminum foil coating during winding. However, the lack of an effective tension adjustment function during the movement of the aluminum foil makes it prone to wrinkles during detection, which may cause deviations in the signal collected by the grayscale meter, thereby affecting the accuracy of the coating uniformity judgment. Therefore, we need to propose an aluminum foil coating detection device. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-4 This utility model provides a technical solution:
[0023] An aluminum foil coating inspection device includes a base plate 1, a first fixing frame 2, two sets of guide rollers 3 and tension rollers 4. The first fixing frame 2 is fixedly installed on the top of the base plate 1, and the two sets of guide rollers 3 and tension rollers 4 are all arranged inside the first fixing frame 2. A fixing plate 5 is fixedly installed on one side of the first fixing frame 2, and an adjustment component 6 for adjusting the tension of the tension roller 4 is provided on the side of the fixing plate 5 near the tension roller 4.
[0024] With the setup of base plate 1, first fixed frame 2, two sets of guide rollers 3, tension roller 4 and adjustment component 6, base plate 1 serves as the bearing platform for the entire device, ensuring the overall structural stability. First fixed frame 2 provides installation space for the two sets of guide rollers 3 and tension roller 4, and the two sets of guide rollers 3 are symmetrically arranged to guide the transmission direction of aluminum foil. Tension roller 4 is located between the two sets of guide rollers 3 and is responsible for adjusting the tension of aluminum foil. With the help of adjustment component 6, the tension of aluminum foil during movement can be adjusted to ensure that aluminum foil remains flat during the inspection process.
[0025] The adjusting assembly 6 includes a motor 61, a threaded rod 62, a push plate 63, a push rod 64, a support plate 65, and a connecting frame 66. The motor 61 is fixedly installed on one side of the first fixed frame 2, and the output end of the motor 61 is fixedly connected to the threaded rod 62 through a coupling. The push plate 63 is threadedly installed on the outside of the threaded rod 62, and two sets of push rods 64 are symmetrically fixed on the side of the push plate 63 away from the fixed plate 5. The ends of the two sets of push rods 64 away from the push plate 63 pass through the support plate 65 and are fixedly connected to the connecting frame 66 for the tension roller 4 to be rotated and installed. The support plate 65 is fixedly installed inside the first fixed frame 2.
[0026] By adjusting the settings of component 6, motor 61 can be selected as a Panasonic MINAS-A6 series servo motor. Motor 61 is fixed to the outside of the first fixed frame 2 by bolts, and its output shaft is rigidly connected to threaded rod 62 through a coupling. This ensures effective power transmission. When motor 61 drives threaded rod 62 to rotate, push rod 64 passes through support plate 65, thereby converting the rotational motion of threaded rod 62 into linear motion of push plate 63. Push plate 63 moves along threaded rod 62, and push rod 64 pushes connecting frame 66 and tension roller 4 to move synchronously, so that tension roller 4 is pressed towards aluminum foil, thereby achieving precise adjustment of the position of tension roller 4.
[0027] The adjustment assembly 6 also includes a slider 67 and a groove 68. The slider 67 is fixedly installed on both sides of the push plate 63, and the groove 68 for the slider 67 to slide is opened on both sides inside the first fixed frame 2.
[0028] With the slider 67 and the groove 68 set, the slider 67 slides into the groove 68, providing precise guidance for the linear movement of the push plate 63, ensuring that the tension roller 4 moves along a fixed trajectory during the adjustment process, avoiding the push plate 63 from tilting or jamming due to uneven force, and ensuring the stability of tension adjustment.
[0029] One end of the threaded rod 62 is rotatably mounted on one side of the support plate 65, and the support plate 65 has two sets of through holes 7 for the push rod 64 to slide inside.
[0030] With the support plate 65 and through hole 7, one end of the threaded rod 62 is rotatably mounted on the support plate 65, providing a fixed fulcrum for the threaded rod 62. This ensures that the threaded rod 62 rotates coaxially under the drive of the motor 61, preventing axial offset or wobbling caused by suspension and ensuring the smoothness of the threaded transmission. At the same time, the through hole 7 on the support plate 65 provides a linear motion track for the push rod 64, allowing the push rod 64 to move only along the axial direction of the through hole 7. This prevents the push rod 64 from swaying radially under the drive of the push plate 63, ensuring the accuracy of the tension roller 4 adjustment trajectory.
[0031] It also includes a detection component 8 for detecting both sides of the aluminum foil coating. The detection component 8 includes a frame 81, a first gray level meter 82, a connecting plate 83, and a second gray level meter 84. The frame 81 is fixedly installed on the top of the base plate 1, the first gray level meter 82 is located at the inner top of the frame 81, the connecting plate 83 is fixedly installed inside the frame 81, and the second gray level meter 84 is located at the bottom of the connecting plate 83.
[0032] With the setting of the detection component 8, the aluminum foil is released from the unwinding roller 10. When the aluminum foil moves into the shaped frame 81, the first gray level meter 82, which is fixed at the top of the shaped frame 81, detects the coating on the upper surface of the aluminum foil. Then, the aluminum foil is guided and transported by the guide roller 3, so that the lower surface of the aluminum foil passes under the second gray level meter 84, which is fixed at the bottom of the connecting plate 83. The second gray level meter 84 detects the coating on the lower surface of the aluminum foil. After the detection is completed, the aluminum foil continues to move and is finally wound up by the winding roller 11. The first gray level meter 82 and the second gray level meter 84 can both be Keyence FS-N11 N model gray level meters. The first gray level meter 82 and the second gray level meter 84 are existing mature detection technologies. They detect the front and back sides of the aluminum foil coating through optical principles. The data connection and transmission method with the controller are common technical solutions in the industry and are not the innovative protection points of this patent, so they will not be described in detail.
[0033] A second fixed frame 9 is fixedly installed on the top of the base plate 1, and an unwinding roller 10 and a take-up roller 11 are rotatably installed inside the second fixed frame 9, with the unwinding roller 10 located above the take-up roller 11.
[0034] By setting up the unwinding roller 10 and the take-up roller 11, the unwinding roller 10 is used to unload the aluminum foil, and the take-up roller 11 is used to take up the aluminum foil. The unwinding roller 10 and the take-up roller 11 are stacked and installed in the second fixed frame 9. Compared with the horizontal arrangement, the floor space occupied by the equipment in the plane direction is greatly reduced, and the vertical space is effectively utilized.
[0035] The unwinding roller 10 and one of the guide rollers 3 are located on the same horizontal plane, and the winding roller 11 and another set of guide rollers 3 are located on the same horizontal plane.
[0036] By having the unwinding roller 10 and the upper guide roller 3 on the same horizontal plane, the aluminum foil can remain relatively flat during movement, which facilitates the first grayscale meter 82 to detect the upper surface of the aluminum foil. Meanwhile, the winding roller 11 and the lower guide roller 3 are on the same horizontal plane, which facilitates the second grayscale meter 84 to detect the lower surface of the aluminum foil, thereby significantly improving the consistency and accuracy of double-sided coating detection.
[0037] Working principle: When this utility model is used, the aluminum foil is drawn out from the unwinding roller 10, passes through two sets of guide rollers 3 in sequence, and is then wound up by the winding roller 11. During testing, the aluminum foil passes through the shaped frame 81. The first gray level meter 82 at the top of the shaped frame 81 tests the front side of the aluminum foil coating. Then, the aluminum foil passes through two sets of guide rollers 3, and the second gray level meter 84 at the bottom of the connecting plate 83 tests the back side of the aluminum foil coating.
[0038] If the aluminum foil tension is insufficient during operation, the motor 61 is started to drive the threaded rod 62 to rotate, which drives the push plate 63 to slide along the slide groove 68. The push rod 64 pushes the connecting frame 66 to make the tensioning roller 4 press the aluminum foil, thereby adjusting the aluminum foil tension and ensuring that the aluminum foil remains flat during the inspection process.
[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
