Description

Technical Field

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

[0002] With the ever-increasing demands for product quality, processing precision, and production efficiency in modern industrial production, thin film materials have been widely used in various fields such as electronics, packaging, medical, and optics. Especially in precision manufacturing processes, static electricity on thin film surfaces has become increasingly prominent, becoming a significant factor affecting product quality and process stability. Static electricity can lead to safety hazards such as dust adsorption, roller entanglement, electric shock, and even fire. Therefore, static electricity elimination technology, as a key control element in thin film processing, directly impacts product yield and equipment operational safety.

[0003] In recent years, electrostatic elimination technologies have mainly included active ion wind elimination, passive conductive material contact elimination, and composite elimination devices. Among them, ion wind bars are widely used in various thin film production lines due to their fast response speed and wide applicability. However, existing solutions still have many shortcomings: First, traditional ion wind bars are mostly fixed installation structures, which are difficult to adapt to thin film materials of different thicknesses or with offset running trajectories, resulting in unstable electrostatic elimination effects; second, under high tension or high-speed operation conditions, the film is prone to vibration due to uneven tension, which in turn affects the electrostatic neutralization efficiency; third, some devices lack manual intervention methods, and cannot perform timely partial discharge treatment in case of sudden electrostatic accumulation or equipment failure, causing continuous production interruption. In addition, existing devices usually do not have tension adjustment functions, making it difficult to effectively control the film's operating state, thus limiting their application performance under complex working conditions.

[0004] In summary, existing thin-film electrostatic elimination technologies still have significant shortcomings in terms of adaptability, controllability, and safety. This invention provides a thin-film electrostatic elimination device that effectively solves the problems of poor adjustment capability and low electrostatic elimination efficiency of traditional devices when dealing with different working conditions by integrating a tension adjustment device with a multi-point adjustable structure and a manual elimination device. It belongs to the cross-technical field of electrostatic control and mechanical adjustment in thin-film processing equipment. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a thin-film electrostatic eliminator, comprising a main body, an ion bar mounted on the frame of the main body, a tension adjustment device mounted on the frame, the tension adjustment device comprising a rectangular rod with several rectangular through holes, a manual elimination device mounted on the rectangular rod, the manual elimination device comprising a first rectangular column inserted into the rectangular through holes, an arc-shaped frame connected to the lower part of the first rectangular column, and a carbon fiber plate fixedly connected to the lower part of the arc-shaped frame.

[0006] A circular limiting plate is welded to the upper part of the first rectangular column, a first spring is sleeved on the outer side of the first rectangular column, and a handle is welded to the circular limiting plate.

[0007] A second rectangular post is inserted into the inside of the rectangular through hole. A rectangular limiting plate is welded to the upper part of the second rectangular post, and a wheel is connected to the lower part of the rectangular limiting plate.

[0008] The rectangular rod has a threaded hole that communicates with the rectangular through hole, and a spring bolt is connected to the threaded hole.

[0009] A motor is mounted on the frame, and the motor is driven by a take-up roller. A feed roller is also connected to the frame.

[0010] The lower part of the tension adjustment device is equipped with a metal roller, and a guide roller is rotatably connected to the frame.

[0011] Compared with existing technologies, the advantages of this invention are as follows: By installing ion bars on the frame, this device can efficiently perform non-contact electrostatic neutralization treatment on the surface of the film during operation, effectively avoiding problems such as dust adsorption, roller entanglement, or electric shock caused by electrostatic discharge, thereby improving product quality and production safety. The ion bars have a fast response speed and wide coverage, making them suitable for film materials of different thicknesses and operating speeds, thus enhancing the applicability and adaptability of the equipment.

[0012] Secondly, the device integrates a tension adjustment mechanism, which includes components such as a rectangular rod, a second rectangular column, wheels, and spring bolts. By adjusting the height of the wheels, precise control of the film tension can be achieved, preventing film vibration or displacement caused by uneven tension and ensuring smooth film operation, thereby improving the stability and consistency of electrostatic elimination. Simultaneously, the spring bolt design allows the adjusted position to be securely locked, further enhancing the device's ease of operation and structural stability.

[0013] Furthermore, the manual discharge device provides an effective emergency measure for partial discharge in sudden situations. The device comprises a first rectangular column, an arc-shaped frame, and a carbon fiber plate. The operator can press down on the carbon fiber plate with a handle, causing it to clamp the film together with the metal roller below. Utilizing the excellent conductivity of the carbon fiber material, static electricity is conducted into the grounding system, achieving rapid and reliable static discharge. Combined with the reset function of the first spring, this not only improves operational safety but also enhances ease of use. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-5 The illustrated thin-film static eliminator includes a main body 4, on which an ion bar 6 is mounted on a frame 41. The ion bar 6 is a device specifically designed to eliminate static electricity, and it is very useful in industrial production and laboratory environments. This device neutralizes the static charge on the surface of an object by generating an airflow with positive and negative charges, thereby preventing static electricity from adversely affecting the production process or experimental results.

[0023] The working principle of the ion bar 6 is based on high-voltage discharge technology. When the ion bar 6 is powered on, the built-in high-voltage generator produces a high voltage, which creates a strong electric field around the discharge needle of the ion bar 6. Under the action of this strong electric field, molecules in the air are ionized, generating positively and negatively charged ions. These ions are then blown out of the ion bar 6 and interact with the static charge on the target surface, achieving the purpose of neutralizing static electricity.

[0024] A tension adjusting device 3 is installed on the frame 41. The tension adjusting device 3 includes a rectangular rod 34 with several rectangular through holes 35. A manual elimination device 9 is installed on the rectangular rod 34. The manual elimination device 9 includes a first rectangular post 93, which is inserted into the rectangular through holes 35. An arc frame 94 is connected to the lower part of the first rectangular post 93. A carbon fiber plate 95 is fixedly connected to the lower part of the arc frame 94. A metal roller 7 is provided at the lower part of the tension adjusting device 3. When the first rectangular post 93 and the carbon fiber plate 95 are pushed down, the film can come into contact with the metal roller 7 and the carbon fiber plate 95, so as to manually remove static electricity.

[0025] A circular limiting plate 92 is welded to the upper part of the first rectangular column 93. A first spring is sleeved on the outside of the first rectangular column 93. A handle 91 is welded to the circular limiting plate 92. A grounding wire is connected to the handle 91, which is not shown in the figure.

[0026] A second rectangular post 36 is inserted into the inside of the rectangular through hole 35. A rectangular limiting plate 37 is welded to the upper part of the second rectangular post 36. A wheel 33 is connected to the lower part of the rectangular limiting plate 37. The tension of the membrane can be adjusted by adjusting the wheel 33 up and down.

[0027] A threaded hole 31 is provided on the rectangular rod 34. The threaded hole 31 is connected to the rectangular through hole 35. A spring bolt 32 is connected to the threaded hole 31 to fix the height of the second rectangular column 36 after adjustment.

[0028] A motor 5 is mounted on the frame 41, and a winding roller 1 is driven by the motor 5. A feeding roller 8 is connected to the frame 41, and a guide roller 2 is rotatably connected to the frame 41.

[0029] Working principle: The device combines an ion bar 6 with a mechanical contact discharge structure to achieve efficient and stable elimination of static electricity on the film surface. It integrates the ion bar 6, tension adjustment device 3, and manual elimination device 9, supplemented by a motor 5 driving the winding and guiding system, forming a complete film static electricity control system.

[0030] In terms of automatic static electricity elimination, the ion bar 6 in the device serves as the main static electricity neutralization unit, and its working principle is based on high-voltage corona discharge technology. When the device is powered on, the built-in high-voltage generator produces a high voltage, forming a strong electric field around the discharge needle, which ionizes air molecules into positive and negative ions. These charged particles are propelled by the airflow and sprayed onto the surface of the operating thin film, where they neutralize the static charge accumulated on the film, thus achieving a non-contact static electricity elimination process. Because the ion bar 6 has advantages such as fast response, wide coverage, and strong adaptability, it can effectively handle thin film materials with high-speed operation or varying thickness, significantly improving the efficiency and stability of static electricity elimination.

[0031] For mechanically assisted static elimination, the device is equipped with a tension adjustment device 3 and a manual elimination device 9. The tension adjustment device 3 consists of a rectangular rod 34, a second rectangular post 36, a wheel 33, and a spring bolt 32. By adjusting the height of the wheel 33, the tension of the membrane along its path can be changed, preventing membrane vibration or displacement caused by uneven tension, thereby improving the stability of the ion bar 6. After adjustment, the position of the second rectangular post 36 can be locked by tightening the spring bolt 32 to ensure a constant tension setting.

[0032] The manual discharge device 9 is used to address partial discharge needs in case of sudden static electricity buildup or equipment failure. This device includes a first rectangular column 93, an arc-shaped frame 94, and a carbon fiber plate 95, with height adjustment achieved via a circular limit plate 92 and a handle 91. The operator can use the handle 91 to press down the carbon fiber plate 95, causing it to clamp the film together with the metal roller 7 below. Utilizing the excellent conductivity of the carbon fiber material, the surface charge of the film is conducted into the grounding system, achieving rapid discharge. Simultaneously, the first spring acts as a reset buffer, facilitating automatic return to the initial position after operation.

[0033] In addition, the device is equipped with a feeding roller 8, a guide roller 2, and a winding roller 1 driven by a motor 5, which enables the film to be continuously and smoothly transported throughout the system, further ensuring the continuity and uniformity of the electrostatic elimination process.

[0034] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
