Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of static electricity elimination, especially relates to a sealing structure for ion bar. BACKGROUND

[0002] Rod-shaped ion generating device (referred to as ion bar) is a kind of fixed type static electricity elimination special equipment.It is easy to install, safe and stable in work, and has the characteristics of fast static electricity elimination speed.It is mainly used in electronic, plastic, silk screen printing, prepress system, image processing and other industries, and also used in plastic film and paper printing roll covering cutting production equipment.

[0003] The principle of ion bar eliminating static electricity is that air is ionized into a large number of positive and negative ions by high-voltage power generator and discharge electrode, and then these ions are blown to the surface of the object by wind, so as to neutralize the static electricity on the surface of the object.

[0004] Specifically, ion bar ionizes air through high-voltage corona discharge at the tip, generating air masses with positive and negative charges.These charged air masses are blown out at high speed, and when the surface of the object has negative charge, it will attract the positive charge in the air mass;Conversely, when the surface of the object has positive charge, it will attract the negative charge in the air mass, thereby achieving the effect of neutralizing static electricity.

[0005] The application scenarios of ion bar are very wide, and it is commonly used in occasions where static electricity needs to be eliminated, such as electronic manufacturing, packaging, printing and other industries.Its working principle is based on the principle of tip discharge and positive and negative charge neutralization, which can effectively eliminate static electricity on insulating materials and objects.In addition, ion bar also has the characteristics of simple use, safety and stability, and is suitable for use in various environments.

[0006] A typical structure of industrial ion bar can be referred to the disclosure in the utility model "resistance coupled industrial frequency alternating current ion bar" with the authorization announcement date of 2020.10.30 and the authorization announcement number of CN211831299U.It sets U-shaped metal shell outside the ion bar shell;A plurality of circuit boards are arranged in the ion bar shell;An even number of discharge electrodes are arranged on the upper surface of each circuit board;An odd number of sheet-shaped high-voltage resistors are arranged on the lower surface of each circuit board;The sheet-shaped high-voltage resistors are arranged horizontally and parallel to the circuit boards on the lower surface of the circuit boards;On each circuit board, two discharge electrodes are connected in parallel and then connected in series with the corresponding sheet-shaped high-voltage resistor.It changes the original longitudinal arrangement of high-voltage resistor to horizontal arrangement without increasing the external size of ion bar, so that the electrical insulation strength of ion bar is obviously improved, the production efficiency is improved, the discharge current of ion bar is increased, the ion production is increased, the power is smaller, and the efficiency ratio is increased.

[0007] During the production and manufacturing process, the high-voltage circuit assembly (see Figure 1The electrode needle a, the electrode needle insert b, the high-voltage circuit board c, the high-voltage resistor d and the metal connector e jointly constitute a high-voltage circuit assembly. The insulating glue sealing (also known as insulating glue pouring or glue pouring) is performed on the high-voltage circuit assembly. Figure 2 Or Figure 4 However, at both ends of the rod body / rod core, as shown in Figure 1 At the joint of the rod core and the end cover and / or the electric connector (also known as the network port connector) and the end cover, the insulating glue pouring is prone to leakage (commonly known as "glue leakage").

[0008] In order to prevent the glue leakage at the joint of the rod core 5' and the end cover 1' and / or the electric connector 2' and the end cover 1', as shown in Figure 1 Generally, a single-component room-temperature curing silicone rubber which does not react with the insulating glue is coated on the joint (such as between the rod core 5' and the end cover 1' and / or between the electric connector 2' and the end cover 1') and at least the surface of the single-component room-temperature curing silicone rubber is dried (surface curing) before the subsequent insulating glue pouring operation is performed.

[0009] However, in the actual production process, it is found that the prior art has the following technical defects:

[0010] 1) The single-component room-temperature curing silicone rubber used for sealing is manually coated, which is not conducive to the standardization of the process operation and the product quality cannot be effectively guaranteed.

[0011] 2) The insulating glue pouring operation must be performed after the single-component room-temperature curing silicone rubber which serves as a sealant is dried (surface curing), which increases the production manufacturing time and reduces the production efficiency.

[0012] 3) If the inner surface or the gap of the joint is not completely coated with the single-component room-temperature curing silicone rubber due to human factors, the glue pouring of the joint of the end cover of the ion rod is prone to leakage.

[0013] How to avoid the glue pouring leakage and simplify the assembly steps to realize simple, reliable and efficient ion rod assembly operation is a technical problem to be solved in the actual assembly and production process. Content of the utility model

[0020] Further, the network port connector has a cylindrical overall shape, the port part thereof passes through the circular through hole at the middle part of the flexible sealing pad and is arranged in the circular mounting through hole at the middle part of the end cover.
