Summary of the invention
Inadequately along pasting, discharge is big outside the ray when plumbous curtain starts at the plumbous curtain that laminates assembling on the existing screening machine, and the low deficiency of production efficiency that should the lead curtain.The purpose of this invention is to provide plumbous curtain of a kind of integral type alpha ray shield and manufacture method thereof.
The technical solution adopted for the present invention to solve the technical problems is: it is made up of first of making one and second portion, and described first is an one-piece construction, and described second portion is closely arranged successively by the plumbous curtain broad ways of number of plate-shaped and constituted.
Further, the plumbous curtain of described sheet is vertical bar shaped or oblique strip shaped or other shapes.
Further, the junction in the described second portion between the plumbous curtain of every adjacent two sheets is provided with one and ends the structure of slitting, and is used to stop the slit between the plumbous curtain of described sheet to extend.
Further, the described structure of only slitting is through hole, riveting parts or hot pressing part.
In addition, the present invention also provides a kind of method of making the plumbous curtain of integral type alpha ray shield, and step is as follows:
A, the plumbous curtain that will make one are divided into first and second portion;
B, described plumbous curtain second portion broad ways cut obtain the plumbous curtain of number of plate-shaped.
The beneficial effect of this patent is: the second portion of the plumbous curtain of integral type alpha ray shield of the present invention is closely arranged by the plumbous curtain of sheet and is constituted, the all-in-one-piece first in plumbous curtain top not only makes the slit between the plumbous curtain of sheet reduce, and, the plumbous curtain of the sheet that is started easier setting back under the pining down of undivided first reduced the chance that ray leaks.In the practical application, when two plumbous curtains of shielding laminated and make the slit between the plumbous curtain of sheet to stagger, the all-in-one-piece first in its top was more convenient for shielding the applying between plumbous curtain, has reduced leaking of ray to greatest extent.In addition, the plumbous curtain of integral type alpha ray shield of the present invention is easy for installation, has saved the trouble that the plumbous curtain of a plurality of strips is assembled one by one.Make in this method that shields plumbous curtain, the plumbous curtain processing technology of integral type is simplified, economical with materials, and production efficiency improves.
