The present invention relates to a kind of manufacturing process for the sealing shell of photoelectric sensor under ultraviolet light environments, include the following steps：Fluoroplastics are spare through high temperature hot melt；Fluoroplastics after hot melt are integrally formed shell through mold injection, shell and incident light Window layer are fluoroplastics integrated injection molding, carry out injection process to fluoroplastics, injection molding rear casing is integrated with incident light Window layer, and waterproofing grade is high.Window layer control thickness is uniform, and fluoroplastics transparency is high after hot melt, and the incident transmitance of full spectrum projection and light can also improve.Transmitance consistency is excellent.Different types can be made, is machined than fluoroplastics proximate matter and saves material, energy conservation and environmental protection is easy to be molded, not by volumetric constraint.Process velocity is fast simultaneously, is easy and fast to mass production.
Description
Technical field
The present invention relates to field of sensor devices, outside specifically a kind of sealing for photoelectric sensor under ultraviolet light environments
The manufacturing process of shell.
Background technology
The existing photoelectric sensor shell to work under ultraviolet light environments is usually that metal and Window layer (translucent material) are logical
Mechanical seal composition or fluoroplastics proximate matter is crossed to complete by being machined.
The sealing material of mechanical seal is usually rubber material, and work under ultraviolet light environments meeting accelerated ageing for a long time, close
Envelope effect can continuously decrease cause reduced service life.Translucent material such as plastics, acrylic, glass or quartz glass, ultraviolet
Surface will also result in some material agings or accumulation dust when being used under luminous environment.Light transmission rate is caused to reduce.
Fluoroplastics are high through over mechanical processing rear surface roughness, are easy to accumulate attached dust, fluoroplastics proximate matter is due to material and adds
The difference of work method can generally be in translucent or milky state, and transmitance at this moment can reduce, especially narrow wave wave band
Spectrum (such as ultraviolet light of the parts UVC) transmitance can be very low.
Invention content
Outside technical problem to be solved by the invention is to provide a kind of sealing for photoelectric sensor under ultraviolet light environments
The manufacturing process of shell, to solve defect existing in the prior art.
The technical solution that the present invention solves above-mentioned technical problem is as follows：
1) fluoroplastics are heated through high temperature spare；
2) fluoroplastics after hot melt are integrally formed shell through mold injection, shell and incident light Window layer are fluoroplastics
Integrated injection molding；
Further, the fluoroplastics are integrally formed through mold injection rear casing and incident light Window layer, window in mold
The polished processing of layer segment, and the surface layer chromium plating of mold injection face；
The beneficial effects of the invention are as follows：Injection process, injection molding rear casing and incident light Window layer one are carried out to fluoroplastics
Change, waterproofing grade is high.Window layer control thickness is uniform, and fluoroplastics transparency is high after hot melt, full spectrum projection and the incidence of light
Transmitance can also improve, especially the spectrum (such as ultraviolet light of the parts UVC) of narrow-band.Transmitance consistency is excellent.It can do
It at different types, is machined than fluoroplastics proximate matter and saves material, energy conservation and environmental protection is easy to be molded, not by volumetric constraint.Add simultaneously
Work speed is fast, is easy and fast to mass production.
Specific implementation mode
The principles and features of the present invention are described below, and the given examples are served only to explain the present invention, is not intended to limit
Determine the scope of the present invention.
A kind of manufacturing process for the sealing shell of photoelectric sensor under ultraviolet light environments includes the following steps：
1) fluoroplastics are heated through high temperature spare；
2) fluoroplastics after hot melt are integrally formed shell through mold injection, shell and incident light Window layer are fluoroplastics
Integrated injection molding；
Further, the fluoroplastics are integrally formed through mold injection rear casing and incident light Window layer, window in mold
The polished processing of layer segment, and the surface layer chromium plating of mold injection face；
The manufacturing process of the present invention has the following advantages that：
1, fluorine material weatherability is strong, is suitble to outdoor long-term work.Not only ultraviolet resistance but also saturating ultraviolet light simultaneously, window is in narrow wave
The light transmission rate of wave band is higher, especially the parts UVC.Than the rubber packing material ultraviolet resistance aging of mechanical seal.
2, light intensity attenuation characteristic is carried, the Window layer being molded by can regard the use of UV wave band variable optical attenuators simultaneously, can
To allow light-sensitive device to be used under high intensity ultraviolet luminous environment；Incident light window layer segment passes through polishing treatment, fluorine modeling in mold
Material injection molding rear surface smoothness is high, higher by the surface flatness of mechanical processing out than material, along with fluoroplastics itself have
Some self-lubricating types and hydrophobicity, surface are not easy to adhere to dirt, especially long-term work in water, and it is dirty will not to accumulate attached mucus shape
Stain.
3, meeting food-grade requirement, the shell done can apply in drinking water water treatment facilities,
4, fluoroplastics acid and alkali resistance, solvent borne are high, are suitable in particular circumstances, especially various to have UVC germicidal applications water
In processing environment.Fluoroplastics have flame retardancy and excellent heat resistance.Brittle temperature is extremely low, shows fabulous cryogenic property note
The product temperature of modeling out has a wide range of application, and is better than ordinary rubber sealing element.
5, there is excellent insulation performance, the shell being molded by is not turned on embedded circuit part, compares metal shell
The protection of circuit can be reduced, circuit volume is reduced.
6, mechanical performance is high, and the product being molded by is suitble to make screw thread, be easier to and metal threaded connection.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention.
