Description

Technical Field

[0001] This utility model relates to the field of thin film static elimination technology, and in particular to a static elimination device for polyimide film processing. Background Technology

[0002] Polyimide film is a high-performance film material. With its excellent mechanical properties, high temperature resistance, radiation resistance, low dielectric constant and high resistivity, polyimide film is widely used in the microelectronics industry as a dielectric space layer, a protective cover layer for metal films and a substrate. During the processing of polyimide film, the friction between the film and the roller or other structures leads to the risk of static electricity.

[0003] Currently, in polyimide film processing, ion bars are typically used to generate positively and negatively charged air masses to eliminate static electricity on the film surface. However, these ion bars are usually directly installed on the frame of the polyimide film processing equipment for single-sided static elimination, or two sets of ion bars are used to perform double-sided static elimination of the polyimide film during processing and transportation. This makes the application of ion bars in the polyimide film processing relatively simple and not conducive to double-sided static elimination of polyimide films using a single set of ion bars. Therefore, we propose a static elimination device for polyimide film processing. Utility Model Content

[0004] The main objective of this invention is to provide an antistatic device for polyimide film processing. It adds a frame structure to the existing ionizer bar to guide the polyimide film through. This frame structure, in conjunction with rollers A, B, and C, guides the polyimide film through the ionizer bar and the antistatic rope, enabling antistatic operation on both sides of the polyimide film. This ensures double-sided antistatic operation during polyimide film processing using a single set of ionizer bars, effectively solving the problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An antistatic device for polyimide film processing includes an ionizing air bar, a support plate, an L-shaped support leg, a folding plate, rotating rollers A, B, and C, a rope winding frame, and an antistatic rope. The ionizing air bar has support plates symmetrically bolted to both sides of its shell. L-shaped support legs are symmetrically welded to the lower surfaces of the support plates. Folding plates are welded to the sides of the L-shaped support legs. Rotating roller A is rotatably mounted on the body of the L-shaped support leg. Rotating rollers B and C are rotatably mounted sequentially from top to bottom on the surface of the folding plate. A rope winding frame is welded to the outer side of the folding plate between rotating rollers A, B, and C. A rope guide groove for inserting the antistatic rope is provided on one side of the folding plate of the rope winding frame. Mounting holes are provided on the surface of the L-shaped support legs.

[0007] Furthermore, a groove A is provided at the L-shaped support foot between the angle plate and the support plate, and the two roller heads of the rotating roller A are inserted into the L-shaped groove cavity of the groove A.

[0008] By adopting the above technical solution, and by opening the groove A at the L-shaped support, the two sides of the roller head of the rotating roller A can be firmly locked, ensuring that the rotating roller A will not loosen or fall off during rotation.

[0009] Furthermore, the angle plate has grooves B and C at the two sets of inclined plates away from the L-shaped support, and the roller heads of rollers B and C are respectively inserted into the L-shaped groove cavities of grooves B and C.

[0010] By adopting the above technical solution, grooves B and C are opened on the angle plate, which can respectively insert rollers B and C, helping to maintain the stability of rollers B and C when they rotate at the angle plate.

[0011] Furthermore, the frame rod of the rope winding frame is welded to the surface of the angle plate, and the surface of the frame rod of the rope winding frame has protruding support rods for winding the antistatic rope.

[0012] By adopting the above technical solution, the surface of the rope winding frame has raised support rods, which provides sufficient winding space and support points for the antistatic rope. This design not only makes the antistatic winding more neat and orderly, but also facilitates subsequent replacement and maintenance work.

[0013] Furthermore, a connecting rod is welded between the two sets of plates of the angle plate;

[0014] By adopting the above technical solution, welding connecting rods between the two groups of plates of the angle plate can enhance the overall rigidity and stability of the angle plate. This design helps to prevent the angle from deforming or being damaged during use.

[0015] Furthermore, the vertical plate of the support plate is locked to the shell of the ion air bar by bolts, and the bottom plate of the support plate is welded to the vertical plate of the L-shaped support leg. The air outlet of the ion air bar faces the rotating roller A.

[0016] By adopting the above technical solution, the support plate is connected to the shell of the ion bar by bolts and to the vertical plate of the L-shaped support leg by welding. This connection method ensures the stability of the structure and facilitates subsequent disassembly and maintenance. At the same time, the air outlet of the ion bar faces the rotating roller A, which ensures that the blown ion air acts directly on the polyimide film, improving the static elimination effect.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention provides a frame structure for guiding polyimide film through an existing ion bar. This frame structure, in conjunction with rollers A, B, and C, guides the polyimide film through the ion bar and the antistatic rope, enabling antistatic operation on both sides of the polyimide film and ensuring double-sided antistatic operation when processing polyimide film with a single set of ion bars.

[0019] Furthermore, the antistatic rope of the antistatic device is easy to replace, and the design of the rope winding frame makes the winding and arrangement of the antistatic rope simple and quick. At the same time, the various parts of the device are easy to disassemble and clean, making it convenient for users to perform daily maintenance and upkeep. Attached Figure Description

The side of the foot plate of the L-shaped support leg 3 is welded with the folding plate 4. The rotating roller A8 is rotatably installed on the plate body of the L-shaped support leg 3. The rotating roller B9 and the rotating roller C10 are rotatably installed on the surface of the plate body of the folding plate 4 from top to bottom. The outside of the folding plate 4 between the rotating rollers A8, B9, and C10 is welded with the rope winding frame 11, and a rope guide groove 12 for inserting the antistatic rope 13 is opened at the folding plate 4 on one side of the rope winding frame 11. The foot plate surface of the L-shaped support leg 3 is provided with mounting holes.

[0025] Among them, a groove A5 is provided at the L-shaped support foot 3 between the angle plate 4 and the support plate 2, and the two roller heads of the rotating roller A8 are inserted into the L-shaped groove cavity of the groove A5.

[0026] By adopting the above technical solution, by opening the groove A5 at the L-shaped support 3, the two sides of the roller head of the rotating roller A8 can be firmly locked, ensuring that the rotating roller A8 will not loosen or fall off during rotation.

[0027] Among them, the angle plate 4 is provided with grooves B6 and C7 at the two sets of inclined plates away from the L-shaped support 3, and the roller heads of rollers B9 and C10 are respectively inserted into the L-shaped groove cavity of grooves B6 and C7.

[0028] By adopting the above technical solution, grooves B6 and C7 are opened on the angle plate 4, which can respectively insert the rotating rollers B9 and C10, which helps to maintain the stability of the rotating rollers B9 and C10 when they rotate at the angle plate 4.

[0029] The frame rod of the rope winding frame 11 is welded to the surface of the angle plate 4, and the frame rod surface of the rope winding frame 11 has a support rod for winding the antistatic rope 13.

[0030] By adopting the above technical solution, the support rods protrude on the surface of the rope winding frame 11, providing sufficient winding space and support points for the antistatic rope 13. This design not only makes the winding of the antistatic rope 13 more neat and orderly, but also facilitates subsequent replacement and maintenance work.

[0031] A connecting rod 14 is welded between the two sets of plates of the angle plate 4;

[0032] By adopting the above technical solution, welding connecting rods between the two sets of plates of the angle plate 4 can enhance the overall rigidity and stability of the angle plate 4. This design helps to prevent the angle plate 4 from deforming or being damaged during use.

[0033] The vertical plate of the support plate 2 is locked to the shell of the ion air bar 1 by bolts, and the bottom plate of the support plate 2 is welded to the vertical plate of the L-shaped support leg 3. The air outlet of the ion air bar 1 faces the rotating roller A8.

[0034] By adopting the above technical solution, the support plate 2 is connected to the shell of the ion air bar 1 by bolts and to the vertical plate of the L-shaped support leg 3 by welding. This connection method not only ensures the stability of the structure but also facilitates subsequent disassembly and maintenance.

[0035] It should be noted that this utility model is an antistatic device for polyimide film processing. The antistatic device is placed in an appropriate position on the polyimide film processing equipment, ensuring that components such as the ion bar 1, rollers A8, B9, C10, and the rope winding frame 11 are in easily operable and observable positions. Depending on the specific processing equipment, the antistatic device is fixed in the appropriate position through the mounting holes at the bottom of the L-shaped support 3. The antistatic rope 13 is checked for integrity and then wound around the rope winding frame with one end grounded, ensuring that the antistatic rope 13 can smoothly pass through the rope guide groove 12 and contact the polyimide film. Then, the power supply to the ion bar 1 is connected. The polyimide film needs to pass over the upper surface of roller A8, then over the lower surface of roller B9 and the upper surface of roller C10 before being led outwards to other processing equipment. Ensure that the antistatic rope 13 is positioned below the polyimide film. Turn on the power switch of the ion bar 1 and adjust its blowing direction and force so that it directly acts on the static-affected area of ​​the polyimide film above roller A8. Then, the un-de-staticized side of the polyimide film can contact the antistatic rope 13 for conductive release. After processing, the power to the ion bar 1 needs to be turned off, and the various components of the antistatic device should be checked regularly for integrity. Any loose or damaged parts should be repaired or replaced promptly.
