Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a detection equipment for the adhesion of metallized films. Background Technique

[0002] A metallized film is wound inside a capacitor. The surface of the metallized film includes a non-metal layer and a metal layer. The adhesion state of the metal layer on the surface of the non-metal layer is an important factor for judging the quality of the metallized film.

[0003] By bonding a tape on the surface of the metallized film and then smoothly peeling the tape vertically, the adhesion state of the metal coating on the surface of the metallized film can be judged by observing whether there is obvious peeling of the metal coating, and further whether the metallized film meets the quality requirements can be judged.

[0004] The traditional peeling detection method depends on the operation experience of the operator to a certain extent. It is necessary to ensure the smooth state of the tape during the peeling process and a relatively consistent peeling angle. Manual operation is likely to cause deviations in the detection results. At the same time, only the good or bad detection of the adhesion state can be achieved through the traditional detection method, and the quantitative analysis of the metal layer cannot be realized. The test results need to be judged visually by humans, and the judgment accuracy is poor and the efficiency is low. Content of the Utility Model

Detailed Embodiments

[0019] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following specifically describes the embodiments of the present utility model with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0020] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only embodiments. Embodiment

[0021] The capacitor is internally wound with a metallized film. The surface of the metallized film includes a non-metal layer 210 and a metal layer 220. The adhesion state of the metal layer 220 on the surface of the non-metal layer 210 is an important factor for judging the quality of the metallized film.

[0022] By bonding a tape to the surface of the metallized film and then smoothly and vertically peeling the tape, the adhesion state of the metal coating on the surface of the metallized film can be judged by observing whether there is obvious peeling of the metal coating, and then it can be judged whether the metallized film meets the quality requirements.

[0023] The traditional peeling detection method depends to a certain extent on the operation experience of the operator. It is necessary to ensure the stable state of the tape during the peeling state and a relatively consistent peeling angle. Manual operation is likely to cause deviation of the detection result; at the same time, through the traditional detection method, only the detection of the quality of the adhesion state can be realized, and the quantitative analysis of the metal layer 220 cannot be realized. The test results need to be judged visually by humans, and the judgment accuracy is poor and the efficiency is low.

[0024] To solve the above problems, referring to the attached Figure 1 - attached Figure 3 , a detection device for the adhesion of a metallized film, includes a conveying device for directionally conveying the metallized film 200. The conveying device controls the metallized film 200 to be in a tensioned conveying state to ensure that the tape and the surface of the metallized film 200 can be in a completely adhered state, ensuring the accuracy of the subsequent adhesion detection result.

[0025] The detection device further includes a first bonding device 400. The first bonding device 400 includes a first unwinding assembly 410, a first winding assembly 420, and a first rolling press assembly 440. The first rolling press assembly 440 bonds the first tape 430 to the surface of the metal layer 220 of the metallized film 200, and the first winding assembly 420 winds up the first tape 430 and records the winding traction force. It also includes a first image detection device 310 located at the rear end of the first bonding device 400. The first image detection device 310 detects the peeling area of the metal layer 220 in a predetermined area, and calculates the adhesion of the metal layer 220 based on the winding traction force and the peeling area of the metal layer 220. Specifically, the winding traction force per unit area = winding traction force / peeling area.

[0026] In the above manner, the winding traction force per unit area of the metallized film 200 can be quantitatively analyzed to automatically detect the adhesion of the metal layer 220 in a predetermined area. The data obtained by the first winding assembly 420 and the first image detection device 310 are automatically transmitted to the central processing unit after being processed, and the adhesion of the metal layer 220 in the predetermined area is automatically calculated and automatically recorded, without manual peeling and observation, greatly improving the accuracy and efficiency of the determination of the adhesion state of the metal layer 220.

[0027] The above image detection method belongs to the prior art. There are significant differences between the surface of the metallized film 200 with the metal layer 220 and without the metal layer 220. The real-time calculation of the peeling area can be achieved by calculating the area of a specific characteristic area. Embodiment

[0028] The difference from Embodiment 1 is that Embodiment 2 further includes a second bonding device 500. The second bonding device 500 includes a second unwinding device 520 and a second rolling press assembly 510. The second rolling press assembly 510 bonds the second tape 530 to the non-metal layer 210 surface of the metallized film 200. By setting the second tape 530 to adhere to the non-metal layer 210 surface, the overall metallized film 200 can be protected, and the non-metal layer 210 can be fixed from the other side, which can prevent the metallized film 200 from being torn and damaged during the measurement process, especially suitable for the metallized film 200 with a thickness below 4.8 microns, ensuring the stability of the detection data.

[0029] Among them, the rolling press assembly includes two relatively arranged power rollers, which are in a tightened state, and both can rotate in a predetermined direction at a predetermined rate, further ensuring the accuracy of the detection result.

[0030] A second image detection device 320 is installed at the front end of the first bonding device 400. The bonding area between the first tape 430 and the metal layer 220 is detected by the second image detection device 320. The second image detection device 320 can detect the bonding area between the metal layer 220 and the first tape 430 at the front end position. The subsequent peeling area is corrected according to the bonding area, further ensuring the accuracy of the detection result.

[0031] Finally, it should be noted that the conveying device includes an unwinding roller 110, a winding roller 120 and a guiding roller. The winding roller 120 continuously rotates to complete the continuous winding of the metallized film 200. Further, the guiding roller includes a guiding roller one 130 and a guiding roller two 140 arranged at intervals. The metallized film 200 can be kept in a taut straight state within a certain length range through the guiding roller one 130 and the guiding roller two 140, so as to realize the installation and arrangement of structures such as the first bonding device 400 and the second bonding device 500. Here, the unwinding roller 110 and the winding roller 120 can be located on the same side or different sides according to needs.

[0032] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent replacements or changes, and should be covered within the protection scope of the present invention.
