Description

Technical Field

[0001] The utility model relates to the technical field of printed circuit manufacturing equipment, in particular to an online peeling mechanism for release paper used in a PET assembly machine. Background Art

[0002] With the development of the electronics industry, thin-film circuits are increasingly used in various electronic devices, particularly in keyboards, control panels, and flexible printed circuits (FPCs). Thin-film circuits typically consist of three layers: an upper circuit layer, a spacer layer, and a lower circuit layer. The upper circuit layer is coated with conductive adhesive to achieve electrical connections for buttons or contacts. To protect the conductive adhesive from contamination and damage, a release paper liner is applied to the surface during the production process.

[0003] However, in actual production, the traditional manual stripping method is often used. This is not only inefficient but also prone to unstable product quality, such as damaged or uneven conductive adhesive. In addition, manual operation increases labor costs and is inconsistent with the trend of modern manufacturing towards automation and intelligence. Utility Model Content

[0004] In order to solve the problems in the above background technology, the utility model provides an online peeling mechanism for release paper for a PET assembly machine.

[0005] The solution adopted by the utility model to solve the technical problem is: an online peeling mechanism for release paper for a PET assembly machine, comprising a frame, a roll-feeding mechanism arranged on one side of the frame for conveying the PET film layer, and a first peeling mechanism arranged on the frame and docked with the roll-feeding mechanism for peeling off the release paper, the first peeling mechanism comprising a pressing component for folding the PET film layer and a blowing and suction component for blowing off the release paper on the folded PET film layer.

[0006] By adopting the above technical solution, when the PET film layer enters the peeling mechanism, the pressing component can be used to fold the PET film layer, causing the release paper to rise, and then the blowing and suction component is used to separate the release paper to complete the automatic peeling process.

[0007] Furthermore, the pressing assembly includes two support frames vertically arranged on both sides of the end face of the frame, two moving rollers horizontally spaced apart between the two support frames for moving the PET film layer, a slide rail fixedly arranged on the inner side of the support frame, a pushing plate slidably connected to the slide rail on both sides and located between the two moving rollers, a pressing shaft arranged at the bottom of the pushing plate, and a driving motor for driving the pushing plate to move along the slide rail.

[0008] By adopting the above technical solution, the movable rollers are continuously moved, the push plate is kept pressed down and does not move, and the pressing shaft is continuously applied to the PET film layer, so that the PET film layer can be continuously bent in the area between the movable rollers.

[0009] Furthermore, a plurality of support members for supporting the pressing shaft to prevent it from bending are evenly spaced between the pressing shaft and the pushing plate.

[0010] By adopting the above technical solution, additional support points can be provided, the rigidity of the pressing shaft can be increased, and the pressing shaft can be prevented from bending due to uneven force during the pressing process.

[0011] Furthermore, the blowing and sucking assembly includes a plurality of blowing heads arranged on one side of the pressing assembly and a suction nozzle arranged on the other side of the pressing assembly.

[0012] By adopting this technical solution, the blower head blows high-pressure air toward the release paper that has lifted up from the PET film layer, separating it from the conductive adhesive. A suction nozzle on the other side assists the blower head in separating the release paper and can also absorb and collect the lifted release paper to prevent it from interfering with subsequent processes.

[0013] Furthermore, a second peeling mechanism is provided behind the first peeling mechanism, and the second peeling mechanism and the first peeling mechanism together constitute a double-station peeling area.

[0014] By adopting the above technical solution, the PET film layer can be subjected to secondary processing to prevent incomplete peeling in the first peeling mechanism, thereby improving the peeling quality.

[0015] Furthermore, a deviation correction mechanism is provided between the feeding mechanism and the first peeling mechanism.

[0016] By adopting the above technical solution, the correction mechanism can detect and adjust the position of the PET film layer in real time to ensure its accurate lateral and longitudinal position during the transportation process. This helps to improve the accuracy of the peeling process and avoid uneven peeling or damage caused by position deviation.

[0017] In summary, the beneficial effects of the present invention are as follows: Through the coordinated use of the press assembly and the blow-and-suction assembly, the present invention enables a rapid and automated release paper peeling process. Specifically, the push plate drives the press shaft, effectively folding the PET film layer, causing the release paper to tilt. Subsequently, the high-pressure air provided by the blow head rapidly separates the release paper from the conductive adhesive, while the suction nozzle collects the peeled release paper. The entire process requires no human intervention, significantly improving production efficiency.

[0018] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention, it can be implemented in accordance with the contents of the specification. In addition, in order to make the above and other purposes, features and advantages of the present invention more obvious and easy to understand, the following preferred embodiments are specifically cited and described in detail with reference to the accompanying drawings.

Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0026] like Figures 1 to 2As shown, an online peeling mechanism for release paper for a PET assembly machine, wherein this embodiment includes a frame 1, a roll-feeding mechanism 2 arranged on one side of the frame 1 for conveying a PET film layer, and a first peeling mechanism 4 arranged on the frame 1 and docked with the roll-feeding mechanism 2 for peeling off the release paper, the first peeling mechanism 4 including a pressing component 41 for folding the PET film layer and a blowing and suction component 42 for blowing off the release paper on the folded PET film layer.

[0027] The frame 1 of this embodiment serves as the supporting structure for the entire mechanism. A reel is provided on one side, serving as a feed mechanism 2. A PET film layer, either an upper circuit layer or a lower circuit layer coated with conductive adhesive, is wound on the reel. A first peeling mechanism 4 is provided on the end face of the frame 1, docking with the feed mechanism 2. The first peeling mechanism 4 comprises a pressing assembly 41 and a blowing / suction assembly 42. When the PET film layer enters the peeling mechanism, the pressing assembly 41 folds the PET film layer. During this folding process, the adhesion between the release paper and the conductive adhesive is broken, causing the release paper to warp. Simultaneously, as the PET film layer is folded, the side blowing / suction assembly 42 separates the release paper, completing the automatic peeling process.

[0028] like Figure 2As shown, the pressing assembly 41 of this embodiment includes two support frames 411 vertically disposed on either side of the end face of the frame 1, two moving rollers 412 horizontally spaced apart between the two support frames 411 for moving the PET film layer, a slide rail 413 fixedly disposed on the inner side of the support frames 411, a push plate 414 slidably connected to the slide rails 413 on both sides and located between the two moving rollers 412, a press shaft 415 disposed at the bottom of the push plate 414, and a drive motor 416 for driving the push plate 414 to move along the slide rails 413. Specifically, the two support frames 411 vertically disposed on either side of the end face of the frame 1 provide support for the overall structure. Two moving rollers 412 are disposed at opposite ends of the two support frames 411 (i.e., the inner side). A certain space is left between the two moving rollers 412, which are located on the same horizontal line, forming a peeling station. The rotation of the moving rollers 412 drives the PET film layer to continuously advance. A push plate 414 is positioned between the two moving rollers 412, and X-axis slide rails 413 are located inside both support frames 411 to provide guidance and support for the push plate 414. The support frames 411 are also equipped with a drive motor 416, which drives the push plate 414 to move vertically up and down along the slide rails 413. A pressing shaft 415, whose diameter is slightly smaller than the width of the release paper on the conductive adhesive, is located at the bottom of the push plate 414. When the PET film layer is unfolded over the two moving rollers 412, the drive motor 416 controls the push plate 414 to move downward along the slide rails 413. The pressing shaft 415 directly acts on the PET film layer, folding the PET film layer. Because the diameter of the pressing shaft 415 is relatively narrow, the contact area with the PET film layer is small, allowing the folding area to be very narrow, maximizing the folding of the PET film layer and causing the release paper to warp. Since the moving roller 412 is constantly moving, it is only necessary to keep the pushing plate 414 stationary so that the pressing shaft 415 acts on the PET film layer, thereby achieving the effect of continuous bending of the PET film layer in the peeling station.

[0029] like Figure 2 As shown, a plurality of support members 417 for supporting the press shaft 415 and preventing it from bending are evenly spaced between the press shaft 415 and the push plate 414 in this embodiment. Considering that the press shaft 415 has a narrow diameter, resulting in weak strength and easy to break and damage, a plurality of support members 417 capable of fixing and supporting the press shaft 415 are evenly and spaced at the bottom of the push plate 414. Each support member 417 is fixed to the other side of the press shaft 415 that acts on the PET film layer, which can provide additional support points without affecting its operation, increase the rigidity of the press shaft 415, and prevent it from bending due to uneven force during the pressing and folding process.

[0030] like Figure 2As shown, the blowing and suction assembly 42 of this embodiment includes a plurality of blowing heads 421 arranged on one side of the pressing assembly 41 and a suction nozzle 422 arranged on the other side of the pressing assembly 41. Specifically, the plurality of blowing heads 421 are arranged on the right side of the pressing shaft 415, and each blowing head 421 can be moved and adjusted to adapt to the different distribution positions of the conductive adhesive on different PET film layers, so that it is aligned with the conductive adhesive position and blows high-pressure gas to the release paper that is raised on the PET film layer to separate it from the conductive adhesive. The suction nozzle 422 on the other side can assist the blowing head 421 in separating the release paper, and can also suck up the blown release paper and collect it to prevent it from interfering with subsequent processes.

[0031] like Figure 2 As shown, in this embodiment, a second peeling mechanism 5 is provided behind the first peeling mechanism 4. Together, the second peeling mechanism 5 and the first peeling mechanism 4 form a dual-station peeling area. The second peeling mechanism 5 is located at the rear end of the first peeling mechanism 4 and has the same structure as the first peeling mechanism 4. After the PET film has been peeled by the first peeling mechanism 4, it enters the second peeling mechanism 5 for secondary processing. This prevents incomplete peeling in the first peeling mechanism 4 and improves peeling quality.

[0032] like Figure 1 As shown, in this embodiment, a correction mechanism 3 is further provided between the feeding mechanism and the first peeling mechanism 4. The correction mechanism 3 can detect and adjust the position of the PET film layer in real time to ensure that its horizontal and vertical positions during the conveying process are accurate. This helps to improve the accuracy of the peeling process and avoid uneven peeling or damage caused by position deviation.

[0033] In summary, the beneficial effects of this embodiment are as follows: this embodiment can realize a fast and automated peeling process of the release paper through the coordinated use of the pressing component 41 and the blowing and sucking component 42. By driving the pressing shaft 415 through the push plate 414, the PET film layer can be effectively folded, so that the release paper is tilted, and then the high-pressure gas provided by the blowing head 421 can quickly separate the release paper from the conductive adhesive, and the suction nozzle 422 is responsible for collecting the peeled release paper. The entire process does not require manual intervention, which greatly improves production efficiency. In addition, multiple support members 417 are provided to increase the rigidity of the pressing shaft 415 to prevent it from bending, ensuring the consistency and stability of the folding area. The double-station peeling design (the first peeling mechanism 4 and the second peeling mechanism 5) ensures that even if the release paper is not completely removed in the first peeling, the second peeling can also be completed completely, thereby improving the quality of the final product.

[0034] The embodiments described above are only preferred implementation methods of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and modifications made by technicians in this field on the basis of the utility model shall fall within the scope of protection of the present invention.
