[0038] like Figure 1 , Figure 2 , Figure 3 As shown, the utility model provides a polyimide film cutting debris collection device, including an air suction structure for negative pressure suction of debris generated by a film cutter 7 during cutting of a film 8, the inlet of the air suction structure is arranged corresponding to the two sides of the film cutter 7 and the inlet direction of the air suction structure can be adjusted, the outlet of the air suction structure is connected to an outlet filter bag 1 for collecting and storing debris; a negative pressure air source structure is arranged between the air suction structure and the outlet filter bag 1 to provide negative pressure suction to the air suction structure.
[0039] According to the cutting characteristics of polyimide and the distribution of debris, the utility model configures a dedicated air suction structure on both sides of the film cutter 7 to improve the efficiency of debris absorption, and its inlet direction can be adjusted to meet the needs of cutter position adjustment, adjust a better debris absorption angle, and improve the efficiency of debris absorption.
[0040] The utility model can realize automatic collection of debris generated in the cutting process of the polyimide film, has high collection efficiency and good effect, reduces debris on the cutter surface, the film cut surface and the film surface, and improves the cleanliness of the film.
[0041] Further, if Figure 1 , Figure 2 , Figure 3 As shown, the suction structure includes a suction main pipe 4, the first end of which is closed, and the second end of which is connected to the outlet filter bag 1; the suction main pipe 4 is connected to a universal suction branch pipe 5 with an adjustable inlet direction, which is located above the film cutter 7, and the inlet of the universal suction branch pipe 5 constitutes the inlet of the suction structure. The utility model is equipped with a universally adjustable universal suction branch pipe 5, which can meet the needs of adjusting the position of the cutter, adjust a better debris absorption angle, and improve the debris absorption efficiency.
[0042] The utility model can realize the negative pressure adjustment of the air suction structure for collecting polyimide film debris, adjust the corresponding appropriate negative pressure for films with different thicknesses, and improve the debris absorption efficiency and the stability of the device operation.
[0043] Furthermore, there are multiple universal suction branch pipes 5, and the opening of each universal suction branch pipe 5 can be adjusted along the three-dimensional direction of the spatial coordinate system (that is, the universal adjustment of the opening of the universal suction branch pipe 5 can be achieved); multiple universal suction branch pipes 5 are arranged at intervals along the width direction of the film.
[0044] During the operation of the film cutter 7, the debris generated will splash to the two sides of the film cutter 7. The universal suction branch pipe 5 is positioned on both sides of the film cutter 7. At the same time, the universal suction branch pipe 5 can be arbitrarily adjusted in three dimensions, so that the debris can be absorbed at the best angle on both sides of the film cutter 7, thereby improving the debris absorption efficiency.
[0045] Further, if Figure 1 As shown, a suction branch pipe regulating valve 6 for adjusting and balancing the suction force of each universal suction branch pipe 5 is provided between the universal suction branch pipe 5 and the suction main pipe 4. The suction force of each universal suction branch pipe 5 is adjusted and balanced by adjusting the suction branch pipe regulating valve 6 to prevent the film from being sucked in due to excessive suction force, and to prevent the debris absorption efficiency from being low due to too little suction force.
[0046] Further, if Figure 1 As shown, the film cutter 7 includes a plurality of cutter heads, and both sides of each cutter head are respectively provided with a universal suction branch pipe 5. The universal suction branch pipe 5 is arranged on both sides of the cutter head to improve the efficiency of debris absorption.
[0047] Furthermore, a negative pressure air source structure is connected to the air suction main pipe 4 , and the negative pressure air source structure generates negative pressure in the pipe section of the air suction main pipe 4 between the first end and the negative pressure air source structure and the universal air suction branch pipe 5 .
[0048] Furthermore, the suction main pipe is located on the pipe section between the first end and the negative pressure air source structure, and a suction main pipe pressure regulating valve 2 for adjusting the suction force of the suction main pipe 4 is arranged near the negative pressure air source structure.
[0049] The suction main pressure regulating valve 2 is used to adjust the suction force of the suction main pipe 4. Different film thicknesses require different suction forces to ensure the debris absorption efficiency while preventing the film from being sucked in.
[0050] Further, if Figure 1 As shown, the negative pressure air source structure is a high pressure vortex air pump 3. Other types of fans can also be used to replace the high pressure vortex air pump 3 in the utility model.
[0051] The impeller of the high-pressure vortex air pump is composed of dozens of blades, which is similar to the impeller of a huge gas turbine. The air between the impeller blades is affected by centrifugal force and moves to the edge of the impeller, where the air enters the annular cavity of the pump body and circulates again from the starting point of the blades in the same way. The circulating airflow generated by the rotation of the impeller leaves the air pump with extremely high energy for use.
[0052] The suction force of the high-pressure vortex air pump 3 is constant. If the suction force in the suction pipe 4 needs to be increased, the suction pipe pressure regulating valve 2 needs to be adjusted down. If the suction force in the suction pipe 4 needs to be reduced, the suction pipe pressure regulating valve 2 needs to be adjusted up.
[0053] The configuration of the suction main pipe pressure regulating valve 2 and the suction branch pipe regulating valve 6 can adjust the suction force of the system and achieve a better debris absorption effect.
[0054] Furthermore, the suction main pipe pressure regulating valve 2 can be replaced by frequency conversion control of the high-pressure vortex air pump 3 , that is, a frequency conversion adjustment unit for adjusting the suction force of the suction main pipe 4 is provided on the negative pressure air source structure.
[0055] Furthermore, the negative pressure range generated in the pipe section between the first end and the negative pressure air source structure of the air suction main pipe 4 and the universal air suction branch pipe 5 is 8-10 KPa.
[0056] During the normal production process, the production operator adjusts and positions the film cutter 7 according to the required film width (the film 8 is installed on the film support 9). During the operation of the film cutter 7, the debris generated will splash to the two sides of the film cutter 7. The universal suction branch pipe 5 is positioned on both sides of the film cutter 7. At the same time, the universal suction branch pipe 5 can be arbitrarily adjusted in three dimensions, so that the debris can be absorbed at the best angle on both sides of the film cutter 7, thereby improving the debris absorption efficiency. Because the film cutter 7 may have multiple blades working at the same time, a universal suction branch pipe 5 is arranged on both sides of each blade.
[0057] The other end of the universal suction branch pipe 5 is connected to the main suction pipe 4. At this time, due to the different distances from the high-pressure vortex air pump 3, the suction forces of the universal suction branch pipes 5 at different positions are different. At this time, it is necessary to install a suction branch pipe regulating valve 6 between the universal suction branch pipe 5 and the main suction pipe 4. The suction force of each universal suction branch pipe 5 can be adjusted and balanced by adjusting the suction branch pipe regulating valve 6 to prevent the film 8 from being sucked in due to excessive suction force, and to prevent the debris absorption efficiency from being low due to excessive suction force.
[0058] The debris enters the air suction pipe 4 through the above structure, and enters the outlet filter bag 1 through the high-pressure vortex air pump 3 along the air flow direction. The outlet filter bag 1 is a filter bag installed at the air outlet of the high-pressure vortex air pump 3, which is used to receive the debris sucked in by filtration to prevent the debris from being discharged into the air near the equipment and causing secondary pollution.
[0059] The suction main pipe pressure regulating valve 2 is installed on the suction main pipe 4 near the high-pressure vortex air pump 3. The valve is used to adjust the suction force of the suction main pipe 4. Different film thicknesses require different suction forces to ensure the efficiency of debris absorption while preventing the film 8 from being sucked in. Since the suction force of the high-pressure vortex air pump 3 is constant, if the suction force in the suction main pipe 4 needs to be increased, the suction main pipe pressure regulating valve 2 needs to be adjusted down. If the suction force in the suction main pipe 4 needs to be reduced, the suction main pipe pressure regulating valve 2 needs to be adjusted up.
[0060] As described above, the polyimide film cutting debris collection device of the utility model has the following beneficial effects:
[0061] According to the cutting characteristics of polyimide and the distribution of debris, the utility model configures a proprietary air suction structure on both sides of the film cutter to improve the efficiency of debris absorption, and the inlet direction can be adjusted to meet the needs of adjusting the position of the cutter, adjust a better debris absorption angle, and improve the efficiency of debris absorption;
[0062] The configuration of the suction main pipe pressure regulating valve and the suction branch pipe regulating valve can adjust the suction force of the system and achieve better debris absorption effect.
[0063] The utility model can realize the negative pressure adjustment of the air suction structure for collecting polyimide film debris, adjust the corresponding appropriate negative pressure for films with different thicknesses, and improve the debris absorption efficiency and the stability of the device operation.
[0064] The utility model can realize automatic collection of debris generated in the cutting process of the polyimide film, has high collection efficiency and good effect, reduces debris on the cutter surface, the film cut surface and the film surface, and improves the cleanliness of the film.
