Batt is formed by electrostatic spinning, and the veiling glare that the black tapetum can will be reflected to thereon is absorbed well,
So as to weaken the veiling glare being mapped on medial surface 31.Specifically, the medial surface 31 includes the close optical axis from the thing side 1
OO ' one end tilts the first joint face 32 of extension to image side and inclined from first joint face 32 to away from optical axis OO ' directions
The second joint face 33 tiltedly extended.The image side surface 2 is included from one end of the close image side of second joint face 33 to remote
The first horizontal-extending plane 21 of optical axis OO ' directions.Institute is respectively provided with second joint face 33 and first plane 21
Black tapetum is stated, the veiling glare that the black tapetum can will be reflected to thereon is absorbed, is mapped to so as to weaken well
Veiling glare on second joint face 33 and first plane 21 is to improve image quality.
In present embodiment, as shown in Figure 3 and Figure 4, the black tapetum can also be set on the thing side 1,
The black tapetum is formed by electrostatic spinning.Specifically, can be individually set on the thing side 1 it is described black
Color tapetum, the veiling glare that the black tapetum can will be reflected to thereon are absorbed well, and thing is reflexed to so as to weaken
Veiling glare on side 1 is to improve image quality.In the other embodiment of the present invention or in the thing side 1, institute
State and the tapetum be set in any one of image side surface 2, the medial surface 31, or, can also be the thing side 1,
Any both or three in the image side surface 2, the medial surface 31 set the tapetum simultaneously.Specifically, be according to pressure
Depending on the scope that decrease veiling glare is needed on ring 10.
It should be noted that in present embodiment, the black tapetum can be dumb light black tapetum, in other realities
Apply in mode, or semi-gloss or gloss black tapetum, depending on needs.
The invention further relates to a kind of processing method of pressure ring, idiographic flow is as shown in figure 5, comprise the following steps：
Step S10, there is provided a pressure ring 10, including thing side 1, be oppositely arranged with the thing side 1 image side surface 2, with
And the side wall 3 of the connection thing side 1 and the image side surface 2, the side wall 3 include close to optical axis OO ' medial surface 31 and with
The lateral surface 34 that the medial surface 31 is oppositely arranged, one layer of adhesive is coated on the medial surface 32.
In present embodiment, specifically coating one layer of adhesive on the medial surface 31 and image side surface 2.Specifically,
One end that the medial surface 31 includes the close optical axis OO ' from the thing side 1 tilts the first joint face 32 extended to image side
Include certainly with from first joint face 32 to the second joint face 33 that extension is tilted away from optical axis OO ' directions, the image side surface 2
One end of the close image side of second joint face 33 is to away from the first horizontal-extending plane 21 of optical axis OO ' directions.In step
It is one layer of adhesive of coating on second joint face 33 and first plane 21 in S10, the adhesive is used for by after
The black fine hair sprayed in continuous step is bonded on second joint face 33 and first plane 21.
In present embodiment, one layer of adhesive can also be individually coated on the thing side 1, or, while described
One layer of adhesive is coated on thing side 1.
Step S11, black fine hair is sprayed to the medial surface 31 using electrostatic spinning equipment, the electrostatic spinning equipment
It is 0.01~1kg/min to go out suede amount.
In step s 11, it is to spray black fine hair to the medial surface 31 and image side surface 2 using electrostatic spinning equipment to carry out
Electrostatic spinning.Specifically, can be sprayed using electrostatic spinning equipment to second joint face 33 and first plane 21 black
Color fine hair carries out electrostatic spinning.The process of electrostatic spinning is as follows：Electrostatic spinning equipment is connected with the mains, passes through electrostatic spinning equipment
The high-pressure electrostatic of tens thousand of volts is produced, fine hair is output in shower nozzle, the fine hair in shower nozzle carries negative electrical charge, and mobile shower nozzle is close to institute
The second joint face 33 is stated, fine hair is ascended to heaven onto second joint face 33 in the presence of high voltage electric field from shower nozzle, perpendicular
Shape is implanted on the second joint face 33 for scribbling adhesive.The process of electrostatic spinning is carried out in first plane 21 and second
The process that electrostatic spinning is carried out on joint face 33 is similar.
In present embodiment, it individually can also spray black fine hair to the thing side 1 and carry out electrostatic spinning, or, together
When spray black fine hair to the thing side 1 and carry out electrostatic spinning.
In present embodiment, the suede amount that goes out of the electrostatic spinning equipment can be excellent within the scope of 0.01~1kg/min
Selection of land, the suede amount that goes out of the electrostatic spinning equipment is 0.5kg/min, now the electrostatic spinning equipment go out suede uniformly and measure
It is moderate, to ensure that the fine hair of the electrostatic spinning equipment injection can be equably bonded on the adhesive being coated on pressure ring 10.
Step S12, dry the pressure ring 10.
In step s 12, specifically, pressure ring 10 is dried using dryer, the time of drying is in 2~10min models
Within enclosing, drying temperature is within the scope of 40~50 DEG C, it is preferable that the drying time is 6min, the drying temperature now needed
Spend for 45 DEG C, such duration and temperature had both ensured that the fine hair of the electrostatic spinning equipment injection can stably be bonded at adhesive
On, it can prevent that overlong time or temperature are too high and cause fine hair to be destroyed again.
Step S13, the unnecessary fine hair on the surface of pressure ring 10 is blown down using high pressure air pressure gun, is formed on the medial surface 31
One layer of black tapetum.
In previous step, there is part fine hair to be not fully locked on pressure ring 10, or be adhered to the table of other fine hair
Face, if do not removed, it can be come off in assembling procedure, pressure ring 10 and other elements are polluted.
In step s 13, high pressure air pressure gun air-flow area coverage is big, and regulating wind power, therefore can quickly blow down institute
The unnecessary fine hair on the surface of pressure ring 10 is stated, ensures to need the region of electrostatic spinning to form one layer of black tapetum on pressure ring 10, this
It is one layer of black tapetum of formation on the medial surface 31 and image side surface 2, specifically described second in embodiment
One layer of black tapetum is formed on joint face 33 and first plane 21, the black tapetum, which can weaken, reflexes to pressure ring
Veiling glare on 10.
In present embodiment, one layer of black tapetum can also be individually formed on the thing side 1, or, while
One layer of black tapetum is formed on the thing side 1.
The step of various methods divide above, be intended merely to describe it is clear, can be merged into when realizing a step or
Some steps are split, are decomposed into multiple steps, as long as including identical logical relation, all protection domain in this patent
It is interior；To either adding inessential modification in algorithm in flow or introducing inessential design, but its algorithm is not changed
