[0001] This utility model relates to the field of precision die-cutting technology, specifically an automatic detection device for the front and back sides of a release film bottom film. Background Technology

[0002] In industries where release films are widely used, such as electronic component packaging, self-adhesive products, and lithium battery separator manufacturing, the production and processing procedures are complex and delicate. As a key material, the correct use of the front and back of the release film directly affects the product quality and performance.

[0003] Currently, the main products are foam and thermally conductive adhesive. The design process involves first making the product, then removing the outer frame waste, and finally manually attaching the final shipping backing film to the adhesive side of the product. The backing film is sliced ​​by a slicing machine and then stacked together. Sometimes, the slicing personnel will place the backing film upside down, which may not be detected during manual application. The current manual process requires another inspection, using tape to confirm the correct orientation, which is very time-consuming and labor-intensive. Even with long-term testing and muscle memory, there may be instances of missed detection, rendering the product unusable. Utility Model Content

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments of the present invention can be combined with each other.

[0022] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device 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 utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] Example 1: Please refer to Figure 1 and Figure 2An automatic detection device for the front and back sides of a release film bottom film includes a base 1, which can be configured into a circular, fan-shaped, or rectangular shape as needed. A support component 2 is fixedly connected to the top of the base 1, and a front and back detection component 3 is mounted on the support component 2. The support component 2 defines the position of the front and back detection component 3, and the bottom film abuts against the front and back detection component 3. The detection device also includes an abutting component 4 that abuts the bottom film against the front and back detection component 3. The front and back detection component 3 can employ various detection methods, such as using a high-tech surface adhesion analyzer to analyze the front and back sides.

[0026] Please see Figure 3 The support assembly 2 includes a fixed column 5 fixedly connected to the base 1. A sliding sleeve 6 is slidably connected to the fixed column 5, and a screw 7 is rotatably connected to the top of the sliding sleeve 6. The lower end of the screw 7 is threadedly connected to the fixed column 5. By sliding the sliding sleeve 6 on the outside of the fixed column 5, the height of the sliding sleeve 6 can be adjusted. The adjustment is made by rotating the screw 7. Under the rotational force of the screw 7, the relative position between the sliding sleeve 6 and the fixed column 5 changes, thereby adjusting the overall height of the support assembly 2. The top of the screw 7 is provided with an internal hexagonal notch, which can be used to adjust the height with a wrench.

[0027] Please refer to section 4. The front / back detection assembly 3 includes a detection plate 8. An adhesive roller 9 is rotatably connected to the bottom of the detection plate 8, and the roller 9 abuts against the base film. The front / back detection assembly 3 is connected to the outside of the sliding sleeve 6. This application discloses a simple, low-cost, and effective front / back detection assembly 3. The roller 9, located below the detection plate 8, contacts the base film to determine whether the upper surface of the base film is a release surface. One or more rollers 9 are provided. When the base film is pulled out from its placement position, the front / back orientation of the base film is determined based on the resistance encountered. Since the base film has a release surface and a PET surface, the front release surface has silicone oil and can be easily pulled out, while the back surface is made of PET and cannot be removed. Therefore, manual adjustment of the front / back orientation of the base film is required to avoid the base film being applied backwards.

[0028] The forward and reverse detection component 3 is slidably connected to the sliding sleeve 6. The bottom film is placed between the base 1 and the roller 9. The abutment component 4 includes a first spring 10 fixedly connected to the outside of the sliding sleeve 6. The roller 9 abuts against the bottom film under the spring force of the first spring 10. A groove 11 is provided on the side of the sliding sleeve 6, and the forward and reverse detection component 3 is slidably connected to the groove 11.

[0029] The sliding groove 11 restricts the freedom of the forward and reverse detection component 3 to slide up and down. The first spring 10 causes the forward and reverse detection component 3 to press against the upper surface of the bottom film. As the bottom film is continuously pulled away, the forward and reverse detection component 3 continues to descend, thereby realizing continuous forward and reverse detection.

[0030] Example 2: This example discloses another implementation of the forward and reverse detection component 3. Specifically, the forward and reverse detection component 3 is fixedly connected to the sliding sleeve 6. The abutment component 4 includes a second spring 12 fixedly connected to the base 1. A supporting base plate 13 is fixedly connected above the second spring 12, and the bottom film is placed between the supporting base plate 13 and the roller 9. In this example, the second spring 12 causes the supporting base plate 13 to move upward continuously. During the process of removing the bottom film, the position of the forward and reverse detection component 3 remains unchanged. As the bottom film is removed, the top layer of the bottom film moves upward continuously, thereby realizing forward and reverse detection. In this structural design, since the removal position remains unchanged, the ease of removal operation is improved. If automation is improved during the removal operation, there is no need to constantly adjust the removal position.

[0031] Please see Figure 5 Four second springs 12 are provided, located at the four corners of the supporting base plate 13. Four guide columns 14 located inside the second springs 12 are fixedly connected above the base 1. The guide columns 14 are slidably connected to the supporting base plate 13. The multiple guide columns 14 guide the supporting base plate 13 from all sides, resulting in better stability.

[0032] Please see Figure 6 A second spring 12 is provided, located at the center below the support base plate 13. A telescopic rod 15 is fixedly connected above the base 1, and the telescopic rod 15 is located inside the second spring 12. The upper end of the telescopic rod 15 is fixedly connected to the support base plate 13. The telescopic rod 15 ensures that there are no interference structures around the upper surface of the support base plate 13. Although the support stability is slightly reduced, it facilitates the operator's removal operation and avoids the situation where the hand touches the guide column 14 during the removal of the bottom membrane.

[0033] Furthermore, this application only applies to the testing when the bottom film is stacked horizontally. Without changing the design concept, the equipment can also be set horizontally, in which case the same testing operation can be performed when the bottom film is placed vertically.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
