[0022] Embodiment
[0023] The following is further described in conjunction with specific embodiments. Referring to Figures 1 - 3 As shown, this embodiment is a device for detecting the adhesion of a pre-coated film coating, including a detection table 1 and a film pressing plate 2. The film pressing plate 2 is arranged above the detection table 1, and a detection hole 21 is provided in the middle of the film pressing plate 2; a scribing detector 3 is arranged above the detection hole 21, and the scribing detector 3 includes a scribing needle 32 and a rotating plate 31. The scribing needle 32 is arranged on the edge side of the rotating plate 31, and the tail end of the rotating plate 31 is connected to a mounting plate 4. The top end of the mounting plate 4 is connected to a lifting cylinder 6; a cylinder tube 5 is installed on the upper surface of the film pressing plate 2. A return spring 51 is arranged in the cylinder tube 5. Pressing columns 41 for accessing the cylinder tube 5 and abutting against the return spring 51 are arranged at both ends of the mounting plate 4; specifically, first, the pre-coated film to be detected is placed on the detection table 1 and moved to the lower side of the film pressing plate 2. The lifting cylinder 6 drives the mounting plate 4 and the scribing detector 3 to move downward as a whole, so that the film pressing plate 2 clamps the pre-coated film to be detected between the detection table 1 and the film pressing plate 2. A part of the pre-coated film is exposed from the detection hole 21. The lifting cylinder 6 further moves downward, pressing and squeezing the return spring 51. The scribing needle 32 extends into the detection hole 21, and the driving motor drives the rotating plate 31 to rotate. The scribing needle 32 rotates around the detection hole 21 and scribes circles on the surface of the pre-coated film. The adhesion is judged by the scratches or coating peeling on the surface of the pre-coated film. During this detection process, the fixing effect of the pre-coated film is good, and the film shifting situation is not likely to occur.
[0024] As Figure 1 shown, this embodiment further includes a hanging frame 7 and a bottom plate 8. The hanging frame 7 is installed on the bottom plate 8. The detection table 1 is arranged on the bottom plate 8, and the lifting cylinder 6 is fixedly installed on the hanging frame 7; specifically, the entire mechanism is suspended on the hanging frame 7, and a gap for the pre-coated film to extend is left between the film pressing plate 2 and the detection table 1; and the surfaces of the film pressing plate 2 and the detection table 1 are kept parallel.
[0025] In order to facilitate the movement of the pre-coated film to be detected under the detection hole 21, a chute 81 for placing the detection table 1 is provided on the bottom plate 8, and the chute 81 passes through from the lower side of the film pressing plate 2; specifically, the detection table 1 drives the pre-coated film to move along the chute 81, which is convenient for taking and placing, and also convenient for changing different detection positions on the pre-coated film.
[0026] Referring to Figure 1 and Figure 3 As shown, in this embodiment, the scribe needle 32 is provided with at least two circumferentially evenly spaced around the rotating plate 31; it also includes a cleaning oil sponge 33, and the cleaning oil sponge 33 is arranged between adjacent scribe needles 32; specifically, in order to avoid the influence of oil stains on the film surface on the detection result, during the rotation of the rotating plate 31, the cleaning oil sponge 33 will first clean the coating surface that will come into contact with the scribe needle 32.
[0027] In addition, the cleaning oil sponge 33 is in a crescent shape, and its setting position coincides with the movement trajectory of the scribe needle 32.
[0028] Referring to Figure 3 As shown, a blowing head 34 is provided in the middle of the rotating plate 31 in this embodiment; specifically, in order to ensure the cleanliness of the surface of the pre-coated film during the detection process, when the scribe needle 32 makes a circle, the blowing head 34 first cleans the fine dust on the film surface.
[0029] As Figure 3 shown, a number of fixed suction cups 11 are provided on the upper surface of the detection table 1; specifically, when the pre-coated film to be detected is placed on the detection table 1, the fixed suction cups 11 provide a small suction force to fix it, and cooperate with the pressing of the film pressing plate 2 to further prevent problems such as wrinkles or offsets of the pre-coated film during the detection process, and the fixing effect is better.
[0030] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
