Description

Technical Field

[0001] This application relates to the field of release film peeling technology, and in particular to a peeling fixture and film application equipment. Background Technology

[0002] Release films are widely used in industries such as packaging, electronics, and printing. They are composed of a release film and a backing paper, and often need to be separated during actual use. Therefore, the peeling process between the release film and the backing paper is a crucial step before subsequent processing or use, and its effectiveness directly affects product quality and production efficiency.

[0003] Currently, the peeling of release composite films is mostly done manually or with simple mechanically assisted peeling devices. Manual peeling is not only labor-intensive and inefficient, but also makes it difficult to guarantee peeling accuracy. Improper operation can easily lead to wrinkles, damage, or contamination of the film material, making it particularly unsuitable for large-scale continuous production.

[0004] While existing mechanically assisted peeling devices can replace manual labor to some extent, they have obvious drawbacks: some devices lack effective guiding and limiting structures, and the release film is prone to deviation and wrinkling during the conveying process, resulting in incomplete separation of the release film and the backing paper or deviation in the separation position; other devices have complex structures and are difficult to adapt to the peeling requirements of release films of different specifications, which limits their promotion and application in industrial production. Utility Model Content

[0005] The purpose of this application is to provide a peeling fixture and film-applying equipment to address, to some extent, the problems of manual peeling in existing technologies. Manual peeling is not only labor-intensive and inefficient, but also lacks precision, easily leading to wrinkles, damage, or contamination of the film due to improper operation, making it particularly unsuitable for large-scale continuous production. Furthermore, some devices lack effective guiding and limiting structures, causing the release film to easily deviate or wrinkle during transport, resulting in incomplete separation or misalignment between the release film and the backing paper. Other devices have complex structures, making them difficult to adapt to the peeling requirements of release films of different specifications, thus limiting their widespread application in industrial production.

[0006] According to a first aspect of this application, a peeling tool is provided, disposed on a conveyor table, for separating the release film and the backing paper of the release composite film; The peeling fixture is provided with a first membrane passage slit that extends through the peeling fixture in a first direction, and the first membrane passage slit is used for the release composite membrane to pass through. The peeling fixture includes a first pressing block and a second pressing block, which are connected along the first direction. A second through-film slit is formed between the first pressing block and the second pressing block along the second direction. The second through-film slit is used for the liner paper to pass through. The second direction intersects with the first direction.

[0007] Preferably, the first pressing block and the second pressing block are connected at at least one end in a third direction, which intersects the plane defined by both the first direction and the second direction.

[0008] Preferably, it further includes a connecting part, which is fixed to the third-direction ends of the first pressure block and the second pressure block, and the connecting part is adapted to connect to the conveyor platform; The side face of the first pressing block facing the conveyor platform is the first end face, and the side face of the second pressing block facing the conveyor platform is the second end face. The first end face and the second end face are coplanar and connected to form a predetermined plane. The end face of the connecting part facing the conveyor platform is the connecting end face, and the connecting end face and the predetermined plane form the first membrane slit in the second direction.

[0009] Preferably, in the second direction, the distance between the predetermined plane and the connecting end face is h, and the thickness of the release composite film is T, wherein T≤h≤3T.

[0010] Preferably, the second pressing block includes a first portion and a second portion spaced apart along the third direction, the first portion and the second portion forming a second membrane slit with the first pressing block in the first direction, and a membrane loading notch forming between the first portion and the second portion along the third direction, the membrane loading notch communicating with the second membrane slit.

[0011] Preferably, in the third direction, the sum of the dimensions of the first portion and the second portion is greater than or equal to one-third of the width of the release composite film.

[0012] Preferably, the side of the second pressing block facing away from the first pressing block is a weight-reducing inclined surface; From the stripping fixture to the conveyor platform, the weight reduction slope gradually tilts away from the first pressure block.

[0013] Preferably, the side face of the first pressing block facing the second pressing block is the peeling blade side face, the side face of the first pressing block facing the conveyor table is the first end face, and the peeling blade side face is perpendicular to the first end face.

[0014] Preferably, the connecting portion is provided with a mounting hole that extends through the connecting portion along the second direction, and the mounting hole is adapted to be connected to the conveyor platform; And / or, the connecting part, the first pressing block and the second pressing block are an integral connecting piece.

[0015] According to a second aspect of this application, a film-applying device is provided, comprising the aforementioned conveyor platform and the peeling fixture described in any of the aforementioned technical solutions. The peeling fixture is disposed on the conveyor platform and thus possesses all the beneficial technical effects of the peeling fixture, which will not be elaborated here.

[0016] Compared with the prior art, the beneficial effects of this application are as follows: The peeling fixture provided in this application, through a first and a second intersecting slit formed by a first and a second pressure block, can guide the release film and the backing paper of the release composite film respectively, enabling them to separate stably along different paths. This avoids problems such as entanglement and overlap during the separation process, significantly improving the orderliness of the separation. The first and second slits limit and guide the release composite film from different directions, effectively constraining the offset and swaying of the film material during the conveying process, ensuring precise separation of the release film and the backing paper, reducing material loss due to separation deviation, and improving the stability of the overall processing quality. Simultaneously, its simple structural design facilitates installation, debugging, and maintenance, and it can be flexibly applied to the peeling requirements of release composite films of different specifications, enhancing its applicability in various production scenarios. Compared with traditional peeling methods, this fixture achieves automated separation guidance through a mechanical structure, reducing efficiency losses caused by manual intervention or complex mechanical operations, accelerating the processing speed of the peeling process, and helping to improve the overall operating efficiency of the production line.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0026] The following reference Figures 1 to 4 This application describes a peeling fixture and film-applying equipment according to some embodiments.

[0027] See Figures 1 to 4 As shown, an embodiment of the first aspect of this application provides a peeling fixture, disposed on a conveyor table 3, for separating the release film 11 and the backing paper 12 of the release composite film 10; the peeling fixture is provided with a first film-passing slit 201 extending through the peeling fixture along a first direction F1, the first film-passing slit 201 for the release composite film 10 to pass through; the peeling fixture includes a first pressing block 21 and a second pressing block 22, the first pressing block 21 and the second pressing block 22 are connected along the first direction, and a second film-passing slit 202 extending through the first pressing block 21 and the second pressing block 22 along a second direction F2 is formed between the first pressing block 21 and the second pressing block 22, the second film-passing slit for the backing paper to pass through, the second direction F2 intersects with the first direction F1.

[0028] According to the peeling fixture provided by the above technical features, the first and second intersecting slits 201 and 202 formed by the first and second pressure blocks 21 and 22 can guide the release film 11 and the backing paper 12 of the release composite film 10 respectively, so that the release film 11 and the backing paper 12 can be stably separated along different paths, avoiding problems such as entanglement and overlap during the separation process, and significantly improving the orderliness of the separation. The first and second slits 201 and 202 limit and guide the release composite film 10 from different directions, effectively constraining the offset and shaking of the film material during the conveying process, ensuring the precise separation position of the release film 11 and the backing paper 12, reducing material loss caused by separation deviation, and improving the stability of the overall processing quality. Meanwhile, its simple structural design makes it easy to install, debug and maintain, and it can be flexibly applied to the peeling requirements of release composite films 10 of different specifications, enhancing its applicability in various production scenarios. Compared with traditional peeling methods, this tooling achieves automated separation guidance through mechanical structure, reducing efficiency losses caused by manual intervention or complex mechanical operations, speeding up the peeling process, and helping to improve the overall operating efficiency of the production line.

[0029] like Figures 1 to 4As shown in the figure, F1 can be an example of the first direction F1 described above, and F2 can be an example of the second direction F2 described above. Preferably, the first direction F1 and the second direction F2 can be perpendicular to each other to adapt to the structure of most existing conveyor platforms 3. However, this is not the case; the angle between the first direction F1 and the second direction F2 can be adaptively adjusted according to the structure of the existing conveyor platform 3. For ease of description, the direction intersecting the plane determined by the first direction F1 and the second direction F2 is defined as the third direction F3. F3 shown in the figure can be an example of the third direction F3 described above. Preferably, the third direction F3 can be perpendicular to the plane determined by the first direction F1 and the second direction F2 described above.

[0030] Preferably, such as Figure 1 and Figure 2 As shown, the first pressing block 21 and the second pressing block 22 are connected at their two ends on the third direction F3, thus forming a single integral structure and enhancing the structural stability of the tooling. This effectively prevents the first pressing block 21 and / or the second pressing block 22 from shifting position due to uneven force during the separation of the release film 11 and the liner paper 12, ensuring the stability and reliability of the separation process, and also facilitating the overall installation and disassembly of the tooling.

[0031] Optionally, not shown in the figure, the first pressing block 21 and the second pressing block 22 can be connected only at one end on the third-direction F3. In other words, the first pressing block 21 and the second pressing block 22 are connected at one end on the third-direction F3, and the other end of the first pressing block 21 and the second pressing block 22 on the third-direction F3 is open. Thus, the release film 11 can be installed through this open end.

[0032] Preferably, such as Figure 1 and Figure 2 As shown, the peeling fixture may also include a connecting part 23, which is fixed to the ends of the first pressing block 21 and the second pressing block 22 in the third direction F3. The peeling fixture is connected to the conveyor table 3 via the connecting part 23. The connection part 23 enables a stable connection between the peeling fixture and the conveyor table 3.

[0033] Preferably, such as Figures 1 to 4 As shown, the connecting part 23 may be provided with a mounting hole 231 that passes through the connecting part 23 along the second direction F2. The mounting hole is suitable for connection with the conveyor table. In this way, the stripping tool and the conveyor table 3 can be connected and fixed by fasteners such as bolts and rivets, which effectively simplifies the assembly difficulty and improves the adaptability of the stripping tool.

[0034] Preferably, such as Figures 1 to 4As shown, there may be two connecting parts 23. The two connecting parts 23 are spaced apart along the third direction F3. Each connecting part 23 is fixedly connected to one end of the corresponding first pressing block 21 and one end of the second pressing block 22 to improve the connection stability between the first pressing block 21 and the second pressing block 22.

[0035] Preferably, such as Figure 1 As shown, the end face of the first pressing block 21 facing the conveyor table 3 is the first end face, and the end face of the second pressing block 22 facing the conveyor table 3 is the second end face. The first and second end faces are coplanar and connected to form a predetermined plane. This coplanarity of the end faces of the first pressing block 21 and the second pressing block 22 prevents wrinkles or jamming of the membrane material during conveying due to uneven end faces. Furthermore, as... Figure 1 As shown, the connecting part 23 has a connecting end face on the side facing the conveyor platform 3. This connecting end face and the predetermined plane form the first through-film slit 201 in the second direction F2 to avoid interference between the conveyor platform 3 and the release composite film 10 during the peeling process.

[0036] Preferably, such as Figure 1 As shown, the side face of the first pressing block 21 facing the second pressing block 22 is the peeling blade side face 210. The peeling blade side face 210 is perpendicular to the first end face (i.e. the end face of the first pressing block 21 facing the conveyor table 3). This facilitates the separation of the release film 11 from the backing paper 12 and avoids the release film 11 pulling the backing paper 12, causing the release composite film 10 to shift as a whole.

[0037] Preferably, in the second direction F2, the distance between the predetermined plane and the connecting end face is h, and the thickness of the release composite membrane 10 is T, where T≤h≤3T. This limits the distance h between the predetermined plane and the connecting end face to a specific range within the thickness T of the release composite membrane 10. This ensures that the release composite membrane 10 passes smoothly through the peeling fixture while also providing appropriate constraint on the membrane material during passage, preventing it from shaking or shifting during separation, thereby improving the separation accuracy between the release membrane 11 and the backing paper 12. If h is too small, the membrane material may have difficulty passing through or even become stuck; if h is too large, the membrane material cannot be effectively constrained, affecting the separation effect.

[0038] Preferably, such as Figure 1 , Figure 2 and Figure 4As shown, the second pressing block 22 includes a first portion 221 and a second portion 222 spaced apart along a third direction F3, forming a film loading notch in the first portion 221 and the second portion 222 in a first direction F1. This film loading notch communicates with a second film-passing slit 202, facilitating the smooth introduction of the release film 11 portion of the release composite film 10 into the second film-passing slit 202 during initial installation, reducing the difficulty of film loading and improving operational convenience. Simultaneously, the first portion 221 and the second portion 222 are positioned at both ends of the first pressing block 21 along the third direction F3, guiding the release film 11 at both ends of the third direction F3, ensuring the stability of the separation guidance of the release film 11 and the backing paper 12 by the second pressing block 22, and ensuring the practicality and efficiency of the tooling.

[0039] Preferably, such as Figure 2 As shown, the dimension of the first part 221 in the third direction F3 is S1, and the dimension of the second part 222 in the third direction F3 is S2. The sum of their dimensions is S1 + S2. The sum of the dimensions of the first part 221 and the second part 222 (i.e., S1 + S2) is greater than or equal to the width of the release composite film 10 (i.e., Figure 2 The value of L shown is one-third of the value of L. In other words, (S1+S2)≥L / 3. This ensures that the second pressure block 22 has sufficient support and guiding area for the release composite membrane 10, so that the membrane material is subjected to uniform force during the separation process. This avoids local deformation of the membrane material or unsmooth separation due to insufficient support, thereby improving the separation effect and product quality.

[0040] Preferably, such as Figure 1 and Figure 2 As shown, the side of the second pressure block 22 facing away from the first pressure block 21 is a weight-reducing inclined surface 223. From the peeling fixture to the conveyor table 3, the weight-reducing inclined surface 223 gradually slopes away from the first pressure block 21. In this way, on the one hand, the contact area between the second pressure block 22 and the liner paper 12 can be effectively increased, thereby ensuring the separation stability of the second pressure block 22 and the liner paper 12; on the other hand, the structure of the weight-reducing inclined surface 223 can effectively reduce the mass of the second pressure block 22, save the amount of manufacturing materials for the peeling fixture, and reduce the manufacturing cost of the peeling fixture.

[0041] Preferably, the size of the second slit 202 in the first direction F1 can be 1mm to 1.5mm. This can accurately limit the release composite film 10, so that the release film 11 and the backing paper 12 can be effectively separated when passing through the slit. At the same time, the film material will not be damaged due to excessive compression because the slit is too narrow, or the separation effect will be poor due to the slit being too wide, thus optimizing the reliability and stability of the separation process.

[0042] Preferably, such as Figures 1 to 4As shown, the connecting part 23, the first pressing block 21 and the second pressing block 22 can be integrated as a single connecting piece, which enhances the overall structural strength and rigidity of the tooling, reduces assembly errors between components, ensures the stability and durability of the stripping tooling, and extends its service life.

[0043] See Figure 3 and Figure 4 As shown, an embodiment of the second aspect of this application also provides a film-applying device, including the above-described conveyor 3 and the peeling fixture described in any of the above embodiments, and thus possesses all the beneficial technical effects of the peeling fixture, which will not be repeated here.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
