Description

Technical Field

[0001] This utility model relates to the technical field of CF conveyor film processing, specifically a CF conveyor film anti-dust and anti-wrinkle slitting device. Background Technology

[0002] In the circuit board manufacturing industry, with the development of the electronics industry, the circuit lines of electronic circuits and chip circuits are becoming more and more refined, and the gaps between copper wires are becoming smaller and smaller, with micron-level and even nanometer-level lines. Especially in the manufacturing of chips, various functional films, such as solder resist films and insulating films, need to be attached to the gaps between copper wires.

[0003] The prerequisite for achieving high-filling precision lamination on the carrier surface of various fine lines and vias is that the CF transfer film must be wrinkle-free and have high cleanliness on both sides. Therefore, when processing the CF transfer film, especially when slitting the CF transfer film, it is necessary to ensure that the debris generated during the cutting process does not enter the subsequent winding.

[0004] Therefore, the existing method of using a suction structure to remove chips is problematic because the width requirements of the CF conveyor film vary in different processing operations. This necessitates adjusting the position of the cutting wheel and then adjusting the position of the suction structure. This not only involves numerous adjustment steps but also makes it easy for the adjusted suction port to deviate from the cutting position, affecting the chip removal effect. Utility Model Content

[0005] The purpose of this invention is to provide a CF conveyor film anti-dust and anti-wrinkle slitting device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a CF conveyor film anti-dust and anti-wrinkle slitting device, comprising a frame and a plurality of guide rollers rotatably mounted on the frame for reversing the CF conveyor film; a feed roller and a take-up drum are detachably mounted on the frame, both of which are driven to rotate by a drive source; it also includes two slitting rollers rotatably mounted on the frame, with a plurality of cutting elements slidably mounted on the slitting rollers, and the cutting elements on the two slitting rollers are staggered to form a slitting position for performing a cutting action on the CF conveyor film; an adjustment unit, mounted on a fixed frame fixed to the frame and connected to the cutting elements, for adjusting the distance between two adjacent cutting elements; the adjustment unit is also equipped with a second suction nozzle, which faces the slitting position, and the second suction nozzle does not misalign with the slitting position when the position of the cutting elements is adjusted.

[0007] The CF conveyor film anti-dust and anti-wrinkle slitting device as described above: the cutting component includes a mounting base slidably mounted on the slitting roller, and a cutting wheel is fixed on one side of the mounting base.

[0008] As described above, the CF conveyor film anti-dust and anti-wrinkle slitting device has at least one strip-shaped limiting block formed on the slitting roller along its axis parallel to the roller, and a strip-shaped limiting groove that slides with the strip-shaped limiting block is formed in the through groove of the mounting base through which the slitting roller passes.

[0009] The CF conveyor film anti-dust and anti-wrinkle slitting device described above: the adjustment unit includes: a support frame that is slidably mounted on the fixed frame at one end, and a collar fixed at the other end of the support frame, the collar being sleeved on the mounting base and rotatably connected to the mounting base; the support frame is also provided with a locking member, the locking member being used to lock the position of the support frame relative to the fixed frame.

[0010] As described above, the CF conveyor film anti-dust and anti-wrinkle slitting device has the second suction nozzle tilted towards the slitting position, and the second suction nozzle is fixedly connected to the support frame through a connecting frame.

[0011] As described above, the CF conveyor film anti-dust and anti-wrinkle slitting device has a slider installed on the side of the support frame facing the fixed frame, and the slider is slidably connected to the slide rail set on the fixed frame.

[0012] As described above, the CF conveyor film anti-dust and anti-wrinkle slitting device has the following configuration: the shaft tube on the take-up drum is connected to the rotating shaft mounted on the frame, and a first suction nozzle connected to the frame is provided at the end of the shaft tube.

[0013] As described above, the CF conveyor film anti-dust and anti-wrinkle slitting device includes at least two unfolding rollers rotatably mounted on the frame. The two unfolding rollers are fixed on the frame and maintain contact with the CF conveyor film.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: multiple second suction nozzles are connected to a blower through a connecting pipe. When the blower is working, a large negative pressure is generated at the position of the second suction nozzle, which sucks the debris generated when the CF conveyor film is cut at the slitting position into the second suction nozzle and discharges it through the blower. This ensures that the debris will not be rolled into the CF conveyor film during the winding process after slitting, and ensures that the cleanliness of both sides of the CF conveyor film after winding meets the requirements of subsequent processes.

[0015] Secondly, to meet different slitting requirements, the position of the cutting part needs to be adjusted. In this embodiment, the position of the second suction nozzle is simultaneously adjusted when the position of the cutting part is adjusted by the set adjustment unit. This ensures that after the cutting part is in the adjusted position, the second suction nozzle is still facing the slitting position, eliminating the need for further position adjustment of the second suction nozzle. This effectively reduces the adjustment process and ensures the accuracy after adjustment, preventing the position of the second suction nozzle from shifting due to the adjustment of the cutting part's position. This effectively ensures the suction effect of the second suction nozzle on debris. The unfolding roller is an arc-shaped roller, with one unfolding roller located at the discharge end of the feeding roller and the other unfolding roller located at the front end of the slitting position. This allows the CF conveying film to be flattened from the middle position to both sides in its width direction, reducing the shrinkage and wrinkling phenomenon of the CF conveying film due to tension stretching.

[0025] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0026] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0027] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0028] Please see Figures 1-8 In this embodiment of the present invention, a CF conveying film anti-dust and anti-wrinkle slitting device includes a frame 1 and a plurality of guide rollers 2 rotatably mounted on the frame 1 for reversing the CF conveying film. A feed roller 3 and a take-up drum 4 are also detachably mounted on the frame 1, both driven to rotate by a drive source. The device also includes two slitting rollers 7 rotatably mounted on the frame 1, each slitting roller 7 having a plurality of cutting elements slidably mounted on it. The cutting elements on the two slitting rollers 7 are staggered to form a slitting position for cutting the CF conveying film. An adjustment unit is mounted on a fixed frame 8 fixed to the frame 1 and connected to the cutting elements, for adjusting the distance between two adjacent cutting elements. A second suction nozzle 12 is also mounted on the adjustment unit, facing the slitting position, and the second suction nozzle 12 does not misalign with the slitting position when the cutting element position is adjusted.

[0029] Multiple second suction nozzles 12 are connected to a blower via connecting pipes. When the blower operates, it generates a large negative pressure at the location of the second suction nozzles 12, which sucks the debris generated when the CF conveyor film is cut at the slitting position into the second suction nozzles 12 and discharges it through the blower. This ensures that the debris will not be rolled into the CF conveyor film during the winding process after slitting, and ensures that the cleanliness of both sides of the CF conveyor film after winding meets the requirements of subsequent processes.

[0030] Secondly, in order to meet different slitting requirements (to achieve slitting of CF conveyor films of different widths), it is necessary to adjust the position of the cutting component. In this embodiment, the position of the second suction nozzle 12 is simultaneously adjusted when the position of the cutting component is adjusted by the set adjustment unit. This ensures that after the cutting component is in the adjusted position, the second suction nozzle 12 is still facing the slitting position, and there is no need to adjust the position of the second suction nozzle 12 again. This effectively reduces the adjustment process and ensures the accuracy after adjustment. It ensures that the position of the second suction nozzle 12 will not shift due to the adjustment of the position of the cutting component, and effectively ensures the debris suction effect of the second suction nozzle 12.

[0031] It should be noted that the driving source mentioned above includes a motor. When the motor is working, it drives the unloading roller 3 and the winding drum 4 to rotate to achieve the driving requirements. This embodiment will not elaborate on this further.

[0032] Further, please refer to Figures 3-7 The cutting component includes a mounting base 16 slidably mounted on the slitting roller 7. A cutting wheel 17 is fixed to one side of the mounting base 16. At least one strip-shaped limiting block 19 is formed on the slitting roller 7 in a direction parallel to its axis. A strip-shaped limiting groove 20 is formed in the through groove on the mounting base 16 through which the slitting roller 7 passes, which slides in cooperation with the strip-shaped limiting block 19. The mounting base 16 is connected to an adjustment unit, which can adjust the position of the mounting base 16 on the slitting roller 7 and keep the adjusted position fixed. By sliding in cooperation between the strip-shaped limiting block 19 and the strip-shaped limiting groove 20, when the mounting base 16 can be adjusted along the position of the slitting roller 7, the rotation of the slitting roller 7 can drive the mounting base 16 and the cutting wheel 17 to rotate synchronously to achieve the cutting requirements.

[0033] Please refer to the following: Figures 3-6 The aforementioned adjustment unit includes a support frame 13 with one end slidably mounted on the fixed frame 8, and a collar 18 fixed to the other end of the support frame 13. The collar 18 is sleeved on the mounting base 16 and rotatably connected to the mounting base 16. A locking member 14 is also provided on the support frame 13, which is used to lock the position of the support frame 13 relative to the fixed frame 8.

[0034] For example, in one embodiment, the locking member 14 includes a threaded rod passing through the support frame 13 and a rotating handle fixed to the threaded rod. By rotating the rotating handle, the threaded rod can be rotated, thereby pressing the end of the threaded rod away from the rotating handle onto the fixed frame 8, thus fixing the position of the support frame 13 relative to the fixed frame 8.

[0035] The mounting base 16 has an annular inner groove, and the collar 18 is fitted into the annular inner groove, so that when the collar 18 moves, it can drive the mounting base 16 to move accordingly, and the mounting base 16 will not be interfered with when it rotates due to the presence of the collar 18.

[0036] The second suction nozzle 12 is tilted toward the cutting position, and the second suction nozzle 12 is fixedly connected to the support frame 13 through the connecting frame 15. Therefore, when the support frame 13 is adjusted in position, the second suction nozzle 12 is adjusted in position accordingly.

[0037] Furthermore, a slider 11 is installed on the side of the support frame 13 facing the fixed frame 8. The slider 11 is slidably connected to the slide rail 10 provided on the fixed frame 8. The slide rail 10 has a T-shaped cross-section. The sliding groove formed on the slider 11 is adapted to the shape of the slide rail 10 to ensure that the slider 11 can only slide along the length direction of the fixed frame 8.

[0038] In another embodiment of this utility model, the shaft tube 401 on the winding drum 4 is connected to the rotating shaft 6 mounted on the frame 1. A first suction nozzle 5 connected to the frame 1 is provided at the end of the shaft tube 401. The first suction nozzle 5 is connected to another blower through a conduit. When the blower is working, it generates a negative pressure at the inlet of the first suction nozzle 5, thereby sucking away the dust generated by the sliding friction between the rotating shaft 6 and the shaft tube 401, so as to further improve the cleanliness of the CF conveyor film after winding.

[0039] For preferred options, please refer to [link / reference]. Figure 1 , Figure 2 and Figure 8 At least two unfolding rollers 9 are rotatably mounted on the frame 1. The two unfolding rollers 9 are fixed on the frame 1 and keep in contact with the CF conveying film. The unfolding rollers 9 are arc-shaped rollers. One unfolding roller 9 is located at the discharge end of the feeding roller 3, and the other unfolding roller 9 is located at the front end of the slitting position (it contacts the unfolding roller 9 first and then is conveyed to the slitting position). This makes the CF conveying film flattened from the middle position to both sides in its width direction, so as to reduce the shrinkage and wrinkling phenomenon of the CF conveying film due to tension stretching.

[0040] 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.

[0041] 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.
