Embodiment Construction

[0011] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0012] see figure 1 and figure 2 , the shielding fixture 200 is used to prevent tiny particles of the coating material from entering the interior of the lens mount 100 when the outer surface of the lens mount 100 is coated. In this embodiment, the lens holder 100 has a stepped through hole 10, and the stepped through hole 10 includes a first accommodating cavity 11 and a second accommodating cavity 12 with successively increasing diameters, wherein the first accommodating cavity The inner wall of the cavity 11 has internal threads 11 .

[0013] The shielding fixture 200 includes a lifting part 210 , an upper baffle 220 , a buffer 230 , a connecting part 240 and a lower baffle 250 . The lifting part 210 , the upper baffle 220 , the buffer part 230 , the connecting part 240 and the lower baffle 250 are arranged coaxially. The upper baffle 220 is integrally...

Abstract

The invention relates to a shading fixture, which is used for preventing a coating material entering the inside of a lens mount during coating on the outer surface of the lens mount. The lens mount is provided with a step-shaped through hole, and the step-shaped through hole comprises a first accommodating cavity and a second accommodating cavity of which the diameters are increased in sequence. The shading fixture comprises an upper baffle plate, a connecting part which is integrated with the upper baffle plate and a lower baffle plate. The diameter of the upper baffle plate is lager than that of the first accommodating cavity. The diameter of the connecting part is less than that of the first accommodating cavity, and the outer surface is provided with outer threads. The lower baffle plate comprises a cylinder of which the diameter is equal to that of the second accommodating cavity, and the lower baffle plate is provided with a blind hole coaxial to the connecting part. The blind hole is provided with inner threads meshed with the outer threads. The outer threads of the connecting part integrated with the upper baffle plate tightly fit to the inner threads of the lower baffle plate, so that the upper baffle plate and the lower baffle plate tightly fit to the lens mount to prevent micro particles of the coating material entering the inside of the lens mount.

Description

technical field [0001] The invention relates to a shielding jig, in particular to a shielding jig which prevents fine particles of coating material from entering the interior of the lens mount when the lens mount is coated, and a lens mount coating method using the shielding jig. Background technique [0002] As stated in the article "Development and Application of Electromagnetic Shielding Film Equipment" (Vacuum Electronics Technology, 2007 (03), 73-74), with the increasing popularity of electronic and electrical products, in order to reduce the weight of the whole machine and reduce costs, more and more More and more electronic products and equipment use plastic casings. And this casing is transparent to electromagnetic interference, and its internal electronic circuits and sensitive components will be interfered by electromagnetic waves and affect the performance of electronic products. In order to meet market demands, many manufacturers prepare electromagnetic shieldin...
