Abstract
The utility model discloses a gum dipping device for prepreg. The gum dipping device comprises a pair of supports. Shaft sleeves are arranged on the supports. A gum dipping shaft is erected between the shaft sleeves. Each shaft sleeve comprises an insulating body. A conductor is embedded in the insulating body. The inner side face of the conductor is electrically connected with the gum dipping shaft, and the outer side face of the conductor is connected to the ground. According to the novel gum dipping device for the prepreg, the conductor is embedded in the insulating body of the shaft sleeve, the inner side face of the conductor is electrically connected with the gum dipping shaft, the outer side face of the conductor is connected to the ground, and accordingly static electricity can be guided into the ground, and the purpose of static electricity removing is achieved.
Description
Technical field
The utility model relates to a kind of gumming device for prepreg, can be applied to copper-clad plate and printed wiring board industry.
Background technology
At present, in the processing procedure of prepreg, need use gumming device, so that glass cloth is immersed in the glue, thereby be made into prepreg.Existing gumming device mainly comprises pair of brackets, respectively is provided with axle sleeve on the support, has set up the impregnation axle between the axle sleeve.Existing impregnation axle all is metal, so it is in operation process, can and glass cloth rub, thereby generation static.In order to eliminate static, existing axle sleeve is copper bush, and copper bush is discharged static by support (or lead is set in addition) ground connection.
Yet, find that in actual use the long-term friction of copper bush and impregnation axle can produce a large amount of copper scales, especially when the contact-making surface of copper bush and impregnation axle exposes outside the glue, its dry friction meeting produces a large amount of copper scales, thereby causes great pollution, has a strong impact on product quality; In addition, the wearability of copper bush is relatively poor, and is easy to wear, and easy frictional heating, and these have all brought adverse effect to gumming device.
At the problems referred to above, Teflon axle sleeve and zirconia ceramics bearing have appearred, yet, because the two all insulate fully, therefore can't solve the problem of static.
Summary of the invention
The purpose of this utility model provides a kind of gumming device for prepreg.
To achieve the above object of the invention, the technical solution adopted in the utility model is: a kind of gumming device for prepreg, comprise pair of brackets, and respectively be provided with axle sleeve on the support, set up the impregnation axle between the axle sleeve,
Described axle sleeve comprises an insulating body, is embedded with electric conductor in the insulating body; The medial surface of electric conductor is electrically connected lateral surface ground connection with described impregnation axle.
Above, the lateral surface ground connection of described electric conductor, thus static is derived, insert the earth.Electric conductor mainly is the static of deriving generation.
Tight fit when described insulating body and electric conductor adopt machining becomes one structure.
In the technique scheme, the lateral surface of described electric conductor is grounded by support.
In the technique scheme, described electric conductor and insulating body are structure as a whole.
In the technique scheme, described insulating body is plastic insulation spare.For example can select polyformaldehyde (POM), Te Folong or PP plastics for use.Preferred Te Folong; Because it has certain self lubricity and hardness height, the strength during as the roll shaft rotating operation supports.
In the technique scheme, described electric conductor is the copper electric conductor.It also can be the aluminium electric conductor.
In the technique scheme, the section of described electric conductor is T-shaped, and lateral surface is greater than medial surface.This structure can realize tight fit when machining.
Because technique scheme is used, the advantage that the utility model compared with prior art has is:
1, the utility model design has obtained a kind of new gumming device that is used for prepreg, in the insulating body of axle sleeve, be embedded electric conductor, and make the medial surface of electric conductor be electrically connected lateral surface ground connection with the impregnation axle, thereby static can be imported the earth, reach the purpose that static is eliminated.
2, the insulating body of axle sleeve of the present utility model can adopt plastic insulation spare, existing hardness and certain self-lubricating function is arranged, and can prevent stall, effectively reduce axle sleeve to the glue pollution problems, effectively promote the service life of axle sleeve and impregnation axle.
3, of the present utility model simple in structure, to be convenient to promote, the cost demand is low.
