Description
Technical Field
[0001] The utility model relates to the technical field of polyimide film processing, and specifically relates to a dust removal device for polyimide film. Background Art
[0002] Polyimide film is a high-performance material with excellent high-temperature resistance, chemical corrosion resistance, electrical insulation and mechanical strength. It is widely used in electronic equipment, aerospace and other high-tech fields for manufacturing insulating layers, protective films and structural components. During the production process of polyimide film, dust particles are easily adhered to its surface, which will affect the use characteristics of the film. Therefore, it is necessary to perform dust removal operations on the film.
[0003] The existing dust removal of polyimide film mainly uses the method of blowing to clean and remove dust. During the process of blowing dust removal, dust particles are easily scattered near the film and are likely to fall back onto the film again, causing secondary pollution, and thus the dust removal effect is not efficient and ideal enough. Content of the Utility Model
[0004] The purpose of the utility model is to provide an efficient dust removal device for polyimide film, which effectively solves the problems raised in the above background art.

The side plates are fixed on one side of the upper surface of the base. A pair of upper and lower symmetrically arranged mounting plates are provided on the side of the side plates. The first guide roller and the second guide roller are arranged on the side of the mounting plates and are arranged in an upper and lower staggered layout. An ultrasonic generating mechanism is jointly provided on the side plates and the two mounting plates for generating ultrasonic vibrations and transmitting them to the first guide roller and the second guide roller. Dust suction mechanisms are provided on both the upper and lower mounting plates for sucking dust from both surfaces of the film.
[0007] Thus, compared with the traditional blowing dust removal, this device uses the method of ultrasonic vibration dust removal and combines the dust suction effect of the dust suction mechanism.

[0009] Furthermore, the dust suction mechanism includes a dust suction box and a dust suction pipe. Dust suction boxes are fixed on the side parts of the two mounting plates. Dust suction cavities are arranged in the two dust suction boxes. Dust suction openings are arranged on the surfaces of the two dust suction boxes close to each other. Flow guiding holes are evenly distributed on the inner end walls of the dust suction openings close to the dust suction cavities. Each flow guiding hole corresponds to communicate with the dust suction cavity. A dust suction pipe is connected to one of the side ends of the two dust suction boxes. The dust suction pipe corresponds to communicate with the dust suction cavity. The ends of the two dust suction pipes are both connected to the suction inlet of an industrial vacuum cleaner.

[0011] Furthermore, a guiding roller is rotatably installed on the side part of the side plate obliquely below the second guide roller.
[0012] Furthermore, a driving mechanism is arranged on the side part of the side plate. The driving mechanism is used to drive the two mounting plates to move closer to or away from each other in the vertical direction for adjustment.
[0013] Furthermore, the driving mechanism includes a guide seat, a bidirectional threaded rod, a driving motor, and a pair of nut seats. The guide seat is vertically fixed on the side part of the side plate. A vertically extending guide groove is arranged on the side part of the guide seat. The bidirectional threaded rod is rotatably installed in the guide groove. The driving motor is fixed on the top of the guide seat, and the output shaft extends into the guide groove and is fixedly connected to the bidirectional threaded rod. The two nut seats are symmetrically and slidably installed in the guide groove and are both threadedly sleeved on the bidirectional threaded rod.

[0028] In the embodiments of the present utility model, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.
[0029] Please refer to Figures 1-6 , a polyimide film dust removal device provided by the present utility model includes a base 1, side plates 2, a first guide roller 3, a second guide roller 4, an ultrasonic generating mechanism 5, and a dust suction mechanism 6. The side plates 2 are fixed on one side of the upper surface of the base 1. A pair of symmetrically arranged upper and lower mounting plates 01 are provided on the side of the side plates 2. The first guide roller 3 and the second guide roller 4 are arranged on the side of the mounting plates 01 and are arranged in a vertically staggered layout. An ultrasonic generating mechanism 5 is provided on the side plates 2 and the two mounting plates 01 together, which is used to generate ultrasonic vibrations and transmit them to the first guide roller 3 and the second guide roller 4. Dust suction mechanisms 6 are provided on both the upper and lower mounting plates 01, and the two dust suction mechanisms 6 are arranged between the first guide roller 3 and the second guide roller 4 and are used to perform dust suction treatment on the two surfaces of the film.
[0030] When using the dust removal equipment provided by the present utility model to perform dust removal treatment on the polyimide film, the film is introduced onto this equipment, bypasses the second guide roller 4, then passes through between the two dust suction mechanisms 6, and then bypasses the first guide roller 3 and is led out of the equipment. The ultrasonic generating mechanism 5 works to generate ultrasonic vibrations, and transmits the vibrations to the first guide roller 3 and the second guide roller 4, causing the first guide roller 3 and the second guide roller 4 to generate ultrasonic vibrations, thereby driving the film segments in contact with the first guide roller 3 and the second guide roller 4 to perform ultrasonic vibrations, so as to shake off the dust particles on both sides of this section of the film. At the same time, by the operation of the two dust suction mechanisms 6, the dust particles shaken off from both sides of the film can be sucked and collected, thereby realizing the ultrasonic dust removal of the film. Compared with the traditional wind blowing dust removal, this equipment uses the ultrasonic vibration dust removal method, combined with the dust suction effect of the dust suction mechanism 6, so that after the dust particles are shaken off, they can be immediately sucked and collected by the dust suction mechanism 6, as much as possible to avoid the dust particles from drifting back onto the film and causing pollution, with better dust removal effect, and can complete the dust removal on both sides of the film at the same time, with higher efficiency.
[0031] Specifically, the ultrasonic generating mechanism 5 includes an ultrasonic generator 51, a pair of transducers 52 and a pair of ultrasonic conduction skeletons 53. The ultrasonic generator 51 is fixed on the side of the side plate 2. The two transducers 52 are respectively fixed on the sides of the two mounting plates 01. The two transducers 52 are both electrically connected to the ultrasonic generator 51. The two ultrasonic conduction skeletons 53 are respectively fixed on the transducers 52. The first guide roller 3 is fixed on the end of one of the ultrasonic conduction skeletons 53, and the second guide roller 4 is fixed on the end of the other ultrasonic conduction skeleton 53. By the operation of the ultrasonic generator 51, a high-frequency electrical signal is generated and transmitted to the transducer 52. The transducer 52 converts the high-frequency electrical signal into mechanical vibration, and then the ultrasonic conduction skeleton 53 transmits the mechanical vibration to the first guide roller 3 and the second guide roller 4, thereby realizing the ultrasonic vibration of the first guide roller 3 and the second guide roller 4.
[0032] Specifically, the dust suction mechanism 6 includes a dust suction box 61 and a dust suction pipe 66. The sides of the two mounting plates 01 are both fixed with dust suction boxes 61. Dust suction cavities 62 are provided in the two dust suction boxes 61. Dust suction ports 63 are provided on the surfaces of the two dust suction boxes 61 close to each other. Flow guiding holes 65 are evenly distributed on the inner end walls of the dust suction ports 63 close to the dust suction cavities 62. Each flow guiding hole 65 communicates with the dust suction cavity 62 correspondingly. One of the side ends of the two dust suction boxes 61 is connected with a dust suction pipe 66. The dust suction pipe 66 communicates with the dust suction cavity 62 correspondingly. The ends of the two dust suction pipes 66 are both connected to the suction port of an industrial vacuum cleaner. Through the negative pressure generated by the operation of the industrial vacuum cleaner, the dust particles shaken off from both sides of the film can be successively sucked into the dust storage tank through the dust suction port 63, the flow guiding hole 65, the dust suction cavity 62 and the dust suction pipe 66, realizing the suction and collection of the dust particles.
[0033] In addition, the film located between the first guide roller 3 and the second guide roller 4 passes horizontally between the two dust suction boxes 61. The two dust suction boxes 61 are symmetrically distributed on the upper and lower sides of the film, ensuring that the distances between the two dust suction boxes 61 and the film are the same, so as to ensure the same dust removal effect on the dust particles, and improve the dust removal effect on the double-sided dust of the film.
[0034] Specifically, cleaning bristles 64 are evenly distributed on the inner end wall of the dust suction port 63 close to the dust suction cavity 62. The cleaning bristles 64 on the upper and lower sides are respectively in contact with the upper and lower surfaces of the film. Since it is inevitable that some impurities are firmly attached to the film and difficult to be shaken off by ultrasonic vibration, when the film passes between the two dust suction boxes 61, the cleaning bristles 64 on the upper and lower sides can be used to scrape off the impurities firmly adsorbed on the film. Coupled with the operation of the industrial vacuum cleaner, the cleanliness of the film surface can be guaranteed to the greatest extent, and the cleaning effect on the film can be further improved.
[0035] Specifically, a guide roller 21 is rotatably installed at the side of the side plate 2 obliquely below the second guide roller 4. The guide roller 21 can be used to smoothly guide the film onto the second guide roller 4.
[0036] Specifically, a driving mechanism 7 is provided at the side of the side plate 2. The driving mechanism 7 is used to drive the two mounting plates 01 to move closer to or away from each other in the vertical direction.
[0037] The driving mechanism 7 includes a guide seat 71, a bidirectional threaded rod 72, a driving motor 73 and a pair of nut seats 74. The guide seat 71 is vertically fixed on the side of the side plate 2. A vertically extending guide groove 711 is provided on the side of the guide seat 71. The bidirectional threaded rod 72 is rotatably installed in the guide groove 711. The driving motor 73 is fixed on the top of the guide seat 71, and the output shaft extends into the guide groove 711 and is fixedly connected to the bidirectional threaded rod 72. The two nut seats 74 are symmetrically and slidably installed in the guide groove 711 and are both threadedly sleeved on the bidirectional threaded rod 72. The two mounting plates 01 are fixedly installed on the side ends of the two nut seats 74 respectively.
[0038] By driving the driving motor 73 to work to drive the bidirectional threaded rod 72 to rotate, the rotating bidirectional threaded rod 72 threadedly drives the two nut seats 74 to approach or move away from each other, and then drives the two mounting plates 01 to move synchronously, realizing the mutual approach or mutual separation and sleeving of the two mounting plates 01, so as to realize the spacing adjustment between the first guide roller 3 and the second guide roller 4 to adapt to films of different thicknesses. In addition, the two dust suction boxes 61 are respectively installed on the mounting plates 01, so that the distance between the two dust suction boxes 61 can be synchronously adjusted following the distance between the first guide roller 3 and the second guide roller 4 to synchronously adapt to films of different thicknesses, with high versatility.
[0039] Specifically, the dust suction pipe 66 is a corrugated flexible pipe. Using the corrugated flexible pipe as the dust suction pipe 66 enables the dust suction pipe 66 to have the ability to be bent and deformed for adjustment, so as to adapt to the position change during the adjustment of the distance between the two dust suction boxes 61.
[0040] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claims involved.
