[0003] The usual method for receiving protective paper is to arrange several pieces of protective paper on the release film and then use equipment to transport them to the processing area for tearing and pasting operations.

[0004] Chinese patent application CN202121970597.4 discloses a protective paper feeding structure, including a release film, a protective paper with adhesive on one side, and a rigid film. The rigid film has a higher hardness than the protective paper. The adhesive side of the protective paper is attached to the release film, and the rigid film is attached to the protective paper. In this design, the protective paper maintains its original shape when torn off or pasted, avoiding arching or sticking together, thanks to the support of the rigid film.

[0005] However, after the protective paper structure arrives, multiple protective papers are regularly attached to the release film. As workers peel off the protective papers one by one and attach them to the module, the release film, which originally had protective paper attached, is prone to deformation and bending as the number of protective papers decreases (e.g., ...). Figure 1 As shown, this affects the tearing of the remaining protective paper, impacting employee operations and reducing work efficiency. Therefore, this utility model discloses a protective paper feeding structure to solve the above problems. Utility Model Content

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0032] As described in the background art, after the protective paper structure arrives, multiple protective papers are regularly attached to the release film. During the process of workers peeling off the protective papers one by one and attaching them to the module, the release film, originally covered with protective paper, is prone to deformation and bending as the number of protective papers decreases (e.g., ...). Figure 1 As shown in the image, this affects the tearing of the remaining protective paper, impacts employee operations, and reduces work efficiency.

[0033] To solve this technical problem, this utility model provides a protective paper feeding structure, which is applied in the field of protective paper.

[0034] For details, please refer to Figure 2-3 The protective paper feeding structure specifically includes a release film 1 and a protective paper 2 with adhesive on one side. The protective paper 2 is arranged and attached to the release film 1. A rigid support frame 3 is provided at the edge of the release film 1 to support the release film 1.

[0035] The protective paper 2 feeding structure provided by this utility model has a rigid support frame 3 set at the edge of the release film 1. During the process of tearing off the protective paper 2, the rigid support frame 3 can provide rigid support for the release film 1, prevent the release film 1 from deforming, ensure the flatness of the release film 1, facilitate the tearing off of the remaining protective paper 2, ensure the work efficiency of workers, and avoid the situation where the operation is difficult and affects the work efficiency of workers.

[0036] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0037] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0038] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0039] Example 1

[0040] Please refer to Figure 2-3 A protective paper 2 feeding structure is provided, which includes a release film 1 and a protective paper 2 with adhesive on one side. The protective paper 2 is arranged and attached to the release film 1, and the adhesive side of the protective paper 2 is bonded to the release film 1. Multiple protective paper 2 are arranged on a single release film 1, and the protective paper 2 is arranged parallel to the release film 1 at equal intervals. Each protective paper 2 has the same size. A rigid support frame 3 is provided at the edge of the release film 1. The rigid support frame 3 is arranged around the four edges of the release film 1, and the width of the rigid support frame 3 is 3-5mm. In this example, the release film 1 is rectangular, and the matching rigid support frame 3 is also rectangular. The outer edge of the rigid support frame 3 is flush with the outer wall of the release film 1. The rigid support frame 3 supports the release film 1. The rigid support frame 3 is made of a material with a certain hardness. In this example, polyimide (PI) is used. One surface of the rigid support frame 3 is adhesive, so that the rigid support frame 3 is directly glued and fixed to the release film 1.

[0041] Furthermore, the protective paper 2 is disposed on the upper surface of the release film 1, and the rigid support frame 3 is disposed on the upper or lower surface of the release film 1. In this example, the rigid support frame 3 is disposed on the upper surface of the release film 1, so that the rigid support frame 3 is arranged around the protective paper 2. In this way, after the release film 1 is stacked, it will not affect the protective paper 2 between the layers, and plays a role in protecting the protective paper 2.

[0042] Furthermore, the protective paper 2 is black, but not limited to black. Depending on the application and product requirements, the protective paper 2 can also be blue, red, green, purple or other colors.

[0043] Example 2

[0044] The material structure of the protective paper 2 provided in Example 1 is further optimized, specifically, as follows: Figure 4 As shown, the protective paper 2 is provided with a tear-off handle 4. The color of the tear-off handle 4 is different from that of the protective paper 2 for easy distinction. The tear-off handle 4 is located at one end of the protective paper 2 and is non-adhesive, so that the tear-off handle 4 does not stick to the release film 1. In this way, when tearing off the protective paper 2, the tear-off handle 4 can be separated from the release film 1 well, thereby tearing the protective paper 2 off the release film 1. Meanwhile, some protective paper 2 needs to be tightly adhered after the bonding module is applied, so there is no need to tear off the handle 4. Instead, the tear-off handle 4 needs to be torn off from the protective paper 2. For this purpose, a separation cutting line 5 is provided between the tear-off handle 4 and the protective paper 2 to facilitate the tear-off handle 4 from the protective paper 2. Furthermore, the two ends of the separation cutting line 5 are set into an open U-shape to form an easy-tear opening, which makes it easy to tear off the tear-off handle 4. At the same time, the tearing force between the tear handle and the protective paper 2 is greater than the adhesive force between the protective paper 2 and the release film 1, which can prevent the tear-off handle 4 from breaking with the protective paper 2 when the tear-off handle 4 pulls the protective paper 2 away from the release film 1.

[0045] Example 3

[0046] The material structure of the protective paper 2 provided in Example 2 is further optimized, specifically, as follows: Figure 5-6 As shown, the release film 1 has positioning holes 6, and the rigid support frame 3 has protruding posts 7. After the rigid support frame 3 is attached to the release film 1, the protruding posts 7 pass through the positioning holes 6, which can ensure the accuracy of the attachment between the rigid support frame 3 and the release film 1, and also facilitate the attachment between the rigid support frame 3 and the release film 1. At the same time, it can also prevent the rigid support frame 3 from slipping or deviating relative to the release film 1. Moreover, there is at least one positioning hole 6 on each of the four edges of the release film 1, which can ensure that each side of the rigid support frame 3 can be positioned, which facilitates the precise positioning and installation of the rigid support frame 3. The protruding posts 7 are integrally formed with the rigid support frame 3.

[0047] Furthermore, after the protruding post 7 passes through the positioning hole 6, it extends a certain distance out of the surface of the release film 1, and a pressing cap 8 is inserted into the extended part. The pressing cap 8 has an insertion hole, and the pressing cap 8 matches the protruding post 7. The protruding post 7 and the insertion hole in the pressing cap 8 are interlocked. By using the pressing cap 8 to connect with the protruding post 7, the connection strength between the rigid support frame 3 and the release film 1 is improved, and it is prevented from detaching from the release film 1 after the adhesive on the rigid support frame 3 weakens. The setting of the pressing cap 8 can also prevent the release film 1 from sticking to the rigid support frame 3 during stacking, causing friction loss.

[0048] The working principle of the protective paper 2 feeding structure provided by this utility model is as follows: A rigid support frame 3 is set at the edge of the release film 1. During the tearing process of the protective paper 2, the rigid support frame 3 can provide rigid support for the release film 1, preventing deformation of the release film 1, ensuring the flatness of the release film 1, facilitating the tearing operation of the remaining protective paper 2, ensuring the work efficiency of workers, and avoiding situations where operational difficulties affect the work efficiency of workers. A tearing handle 4 is set on the protective paper 2, and the tearing handle 4 is not adhered to the release film 1, making tearing convenient. The protective paper 2 improves the efficiency of peeling the protective paper 2 from the release film 1. A separation cutting line 5 is set between the peeling handle 4 and the protective paper 2. After the protective paper 2 is bonded to the module, the unwanted peeling handle 4 can be peeled off from the separation cutting line 5 without affecting the use effect of the protective paper 2. A positioning hole 6 is set on the release film 1, and a protruding post 7 is set on the rigid support frame 3 to facilitate precise positioning and installation of the rigid support frame 3. At the same time, the pressing cap 8 is inserted into the protruding post 7 to improve the connection strength between the rigid support frame 3 and the release film 1.
