Description
Technical Field
The present invention relates to the field of optics, and in particular, to an optical processing device, an optical lens, and a method for manufacturing the optical lens.
Background
Owing to the rapid development of automobile driving assistance systems in recent years, optical lenses are increasingly widely used in automobiles. Furthermore, the requirements for the pixel and safety performance of the optical lens, especially for the vehicle applications, are also increasing for the driving assistance of the vehicle. By increasing the imaging quality requirements of the image pickup device, the image sensor (CMOS) of the image pickup device is moving toward high power. The problem that the lens is atomized is increasingly prominent due to the increase of the internal heat productivity of the camera device, the imaging effect of the lens is greatly influenced, the driving safety is more harmed, and even huge economic loss and personal injury can be caused. The main reason for lens atomization is that water vapor in the inner gap of the optical lens condenses into fine water droplets and adheres to the lens to form water mist, so that clear images cannot be taken and driving safety may be caused.
In addition, when the air moisture in the production area of the optical lens is relatively large, and the air moisture content in the use area of the optical lens is low, the moisture stored in the internal space of the optical lens cannot be discharged, when the internal heat productivity of the camera device is increased, the internal lens of the optical lens is atomized, and the water mist cannot be quickly dissipated, so that the optical lens cannot provide a safe and stable guarantee when being applied to the fields of driving assistance and the like.
Further, lens fogging not only relates to vehicle-mounted optical lenses, but also relates to a problem that needs to be solved by a laser radar device, a projection apparatus and a vehicle-mounted head-up display (HUD) thereof. Various light processing devices are widely used in our daily life, and lens fogging may cause more significant economic loss and personal injury.
Fig. 1 shows a prior art image pickup device, wherein the image pickup device comprises a lens barrel 10 ', an optical lens module 20 ' and a processing module 30 '. The lens barrel 10 ' has an accommodating space 100 ' and a first light-passing opening 101 ' and a second light-passing opening 102 ' communicating with the accommodating space 100 '. The optical lens module 20 ' includes at least one outer lens 21 ', wherein the outer lens 21 ' is retained at the first light passing port 101 ' of the lens barrel 10 '. The processing module 30 ' is held at the second light passage 102 ' of the lens barrel 10 '. The outer lens 21 'is accommodated in the first light-passing opening 101' of the lens barrel 10 'in a limited manner, and the circulation efficiency between the accommodating space 100' and the external space is relatively low.
It should be noted that the image capturing device includes an optical lens 40 ', wherein the optical lens includes the lens barrel 10 ' and the optical lens module 20 '. The lens barrel 10 ' and the optical lens module 20 ' are assembled as the optical lens 40 '. The optical lens 40' may be assembled and applied to other optical processing devices, such as a projection device, a laser radar device, and the like.
The optical lens 40' is a conventional plastic barrel optical lens.
It should be noted that, when the processing module 30 ' processes light to generate heat, the space temperature of the accommodating space 100 ' is higher, and the water vapor in the accommodating space 100 ' meets the cooler outer lens 21 ' and then condenses into fine water drops and attaches to the outer lens 21 ' to form water mist.
The lens barrel 10 'has a front end recess 103', wherein the front end recess 103 'is formed at the front end of the lens barrel 10'. When the outer lens 21 'covers the front end of the lens barrel 10, the front end groove 103' is defined by the outer lens 21 'and the lens barrel 10'. The front end groove 103 'allows the water vapor in the accommodating space 100' to flow to the front end groove 103 'and then to flow outwards, so as to dissipate the water vapor inside the optical lens 40'.
It is worth mentioning that after the existing camera device is operated for a long time at a low temperature, the water mist in the accommodating space 100' of the camera device cannot be quickly dissipated. The water mist is dispersed for a long time, so that the dispersing speed of the water mist is not enough to keep the optical lens module 20' to obtain sufficient light in real time, and the imaging definition cannot be kept in real time, thereby causing great threat to driving safety.
It should be noted that the processing module 30' may be implemented as an image sensor (CMOS), a laser light source, or other projection light source. That is, the processing module 30 'processes light, and during the processing of the light by the processing module 30', the interior of the optical lens is heated to form water mist.
At present, the problem of lens fogging is mainly improved by changing the material of the optical lens 40 'and changing the structural design of the optical lens 40'. By analyzing the material, the lens barrel 10 'can be made of metal to improve the heat dissipation of the optical lens 40' and further improve the water mist problem. However, the metal lens barrel 10 ' is used to replace the common plastic lens barrel, so that the optical lens 40 ' has higher production cost and larger weight, and does not meet the design requirement of light weight of the optical lens 40 '. Analysis on the structure design of the lens barrel promotes the air circulation between the accommodating space 100 ' of the lens barrel 10 ' and the external space to improve the atomization problem of the optical lens, and the improvement effect is weak, and meanwhile, the influence of stray light on the light processing device is increased, so that the normal use of the optical lens 40 ' is influenced.
Therefore, the problem of water fog of the optical lens 40 'is still urgently needed to be improved by a more effective method, especially the problem of water fog of the vehicle-mounted optical lens 40'.

The underlying principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the invention.
It will be understood by those skilled in the art that in the present disclosure, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in an orientation or positional relationship indicated in the drawings for ease of description and simplicity of description, and do not indicate or imply that the referenced devices or components must be in a particular orientation, constructed and operated in a particular orientation, and thus the above terms are not to be construed as limiting the present invention.
Referring to fig. 2A to 2B, the optical processing apparatus according to the first preferred embodiment of the present invention is disclosed and explained in detail, wherein the optical processing apparatus includes a lens barrel 10, an optical lens module 20 and a processing module 30, and the optical lens module 20 and the processing module 30 are respectively disposed at two ends of the lens barrel 10. The lens barrel 10 includes a humidity control bearing portion 11, wherein when the optical lens module 20 and the lens barrel 10 are assembled, the humidity control bearing portion 11 adjusts the humidity of the environment to eliminate most of the water vapor in the lens barrel 10, so as to realize the clear and flat lens of the optical processing device.
The optical processing device includes an optical lens 40, wherein the optical lens 40 includes the lens barrel 10 and the optical lens module 20. The lens barrel 10 and the optical lens module 20 are assembled, then applied to the processing module 30, and then assembled in a matching manner. That is, the optical lens 40 is the lens barrel 10 and the optical lens module 20 assembled.
The lens barrel 10 has a receiving space 100, and a first light-passing port 101 and a second light-passing port 102 communicating with the receiving space 100, wherein the humidity control bearing portion defines the first light-passing port 101. The optical lens module 20 further comprises an outer lens 21 and at least one inner lens 22. The outer lens 21 covers the front end of the humidity control bearing portion 11 to cover the first light passing port 101 of the lens barrel 10. That is, the outer lens 21 is held by the first light passage port 101 of the lens barrel 10. The inner lens 22 is disposed in the accommodating space 100.
It should be noted that the humidity control bearing portion 11 is disposed at the first light opening 102, so that the humidity control bearing portion 11 is close to the outer lens 21 and the inner lens 22, and the optical lens module 20 can be further effectively enhanced to reduce fogging and improve the water mist dissipation effect.
Preferably, the optical axes of the inner lens 22 and the outer lens 21 coincide. The outer lens 21 is disposed outside the inner lens 22 so as to be covered. Further, the optical axes of the inner lens 22 and the outer lens 21 are coincident.
Referring to the first preferred embodiment of the present invention, the processing module 30 is held at the second light passing opening 102 of the optical lens module 20. When the processing module 30 is assembled to the lens barrel 10 in a manner of being placed on a base, the processing module 30 is held at the second light-passing opening 102 of the lens barrel 10.
After the processing module 30 is operated to generate heat, when the humidity inside the accommodating space 100 is relatively high, the water vapor inside the accommodating space 100 is dissipated by the humidity control bearing part 11.
It is worth mentioning that the processing module 30 is held on the second light passing port 102 side of the optical lens module 20. That is, the processing module 30 is disposed outside the optical lens module 20 and near the second light passing port 102 of the optical lens module 20.
The lens barrel 10 includes the humidity control bearing part 11 and a barrel body 12, wherein the barrel body 12 extends backward from the humidity control bearing part 11, and the barrel body 12 defines the second light passing port 102.
It is worth mentioning that the humidity control bearing part 11 has a larger strength, so that the humidity control bearing part 11 can bear the outer lens 21 and/or the inner lens 22 of the optical lens module 20. Furthermore, the humidity control bearing part 10 is disposed close to the optical lens module 20 to better dissipate the water mist of the optical lens module 20, so as to solve the long-term influence of the water mist on the light passing effect of the optical lens.
It is noted that nearby refers to a spatially close position. That is, the humidity control bearing unit 10 is provided at a position close to the optical lens module 20 to enable better dissipation.
The humidity control supporting portion 11 includes a humidity control element 111 and a supporting member 112, wherein the supporting member 112 and the lens barrel main body 12 are integrally formed, and the humidity control element 111 can be flexibly disposed in the accommodating space 100 to dissipate the water vapor in the accommodating space 100.
More preferably, the humidity conditioning element 111 is disposed near a location where fogging is likely to occur, to facilitate the dissipation of water fog, and still more particularly, the humidity conditioning element 111 is disposed near the outer lens 21 and the inner lens 22 of the optical lens module 20.
It is worth mentioning that the support member 112 defines a flow through groove 1121, wherein the flow through groove 1121 of the support member 112 is formed at the front end of the support member 112 such that the cross section of the support member 112 is an annular groove.
When the outer lens 21 is held at the first light passing port 101 of the lens barrel 10, the flow channel 1121 is defined as an annular channel by the outer lens 21 and the bearing member 112. The circulation groove 1121 allows air circulation between the accommodating space 100 and the external space, and when the temperatures of the outer lens 21 and the inner lens 22 are high, the circulation groove 1121 allows air and water vapor to be dissipated outwards, but because the air circulation rate between the accommodating space 100 and the external space is slow, most of water mist dissipation cannot be achieved. More specifically, the outer lens 21 is fastened to the humidity control bearing section 11, supported by the humidity control bearing section 11, and stably retained, so that the humidity control bearing section 11 improves the stability of the optical lens module 20.
With reference to the first preferred embodiment, the humidity conditioning element 111 is disposed between the optical lens modules 20 to quickly dissipate moisture misted by the outer lens 21 or the inner lens 22.
With reference to the first preferred embodiment of the invention, the conditioning element 111 is arranged between the outer lens 21 and the inner lens 22.
The humidity control element 111 is disposed between the outer lens 21 and the inner lens 22, but cannot affect the transmission of the irradiated light through the optical lens module 20, so as to ensure the transmittance of the optical lens module 20 and ensure that the moisture between the outer lens 21 and the inner lens 22 is not attached to the outer lens 21 and/or the inner lens 22 to be liquefied by cooling.
It is worth mentioning that when the external space is cold and the processing module 30 is stably operated, the processing module 30 generates heat, the temperature of the air existing between the outer lens 21 and the inner lens 22 increases, and the circulation rate of the accommodating space 100 to the external space through the circulation groove 1121 is slow, so that the hot air is retained in the accommodating space and cannot be circulated outwards, the water vapor is liquefied when encountering the cold outer lens 21 and adheres to the outer lens 21, and the water mist is dispersed for a long time, so that the optical processing device cannot stably perform optical processing, especially, the optical processing device is very dangerous for the vehicle-mounted camera device for driving assistance. Furthermore, when the processing module 30 is operated stably, the processing module 30 is lighted for a long time, and the water mist dissipation inside the existing optical processing device cannot be dissipated quickly, and cannot meet the requirement of stable use for a long time, especially for some vehicle camera devices with high requirements for stability, which cannot meet the requirements of society and market at all.
The lens barrel 10 of the present invention is provided with the supporting member 112 matching the humidity adjusting element 111 and the air circulation, which greatly facilitates the dissipation of the water vapor in the accommodating space 100.
It is worth mentioning that the humidity control element 111 can rapidly dissipate the water mist to more than 95%, so that the optical processing device can stably operate to ensure the safety of driving.
In addition, the inner lens 22 also has a problem of fogging, when the external environment is larger, more water vapor is brought into the accommodating space 100, so that more water vapor is between the outer lens 21 and the inner lens 22, and when the optical processing device is not in operation, the water vapor is liquefied against the colder inner lens 22 to form water mist attached to the inner lens 22.
It is worth mentioning that the humidity control element 111 not only absorbs moisture, but also adjusts the humidity in the environment, and when the humidity in the environment is too high, the humidity control element 111 absorbs part of the moisture to ensure that the environment keeps a certain humidity level. When the humidity in the environment is too low, the humidity conditioning element can release part of the humidity to balance the humidity of the environment.
Preferably, the humidity control element 111 is made of a humidity control material.
Preferably, the humidity conditioning element 111 is a diatomite/ground limestone composite humidity conditioning material, wherein the composite humidity conditioning material is selected from the following material combinations: there is at least one of calcium silicate, portlandite, calcite and dehydrated diatomaceous earth.
Optionally, the conditioning element 111 is embodied as an inorganic composite material.
Optionally, the humidity controlling element 111 is a cast bamboo charcoal cement-based composite humidity controlling material, wherein the composite humidity controlling material is cast into a ring shape.
Optionally, the composite humidity conditioning material is selected from the following material combinations: at least one of bamboo charcoal, cement, fly ash, quartz sand, additives and water. Alternatively, the conditioning element 111 is implemented as a composite conditioning material based on cast river sediment and slaked lime.
Optionally, the composite humidity control material is implemented as a high molecular polymer water-absorbing composite active mineral soil humidity control material to improve the water absorption performance of the humidity control element 111.
Those skilled in the art will understand and appreciate that the conditioning material used in the conditioning element 111 is not limited in any way.
It will be understood and appreciated by those skilled in the art that the shape of the humidity conditioning element 111 can be designed according to the needs, and the humidity conditioning element 111 can be designed according to the specific shape and the gap of the optical lens module 20, so that the humidity conditioning element 111 can be adapted to most of the optical processing devices, and further, the humidity conditioning element 111 can be adapted to the needs of various optical lenses to perform humidity conditioning on the optical lenses with high requirements.
It is worth mentioning that the greater the number of the humidity control elements 111 provided in the accommodating space 100, the greater the surface area thereof, the better the humidity control effect of the humidity control elements 111.
The humidity control element 111 is disposed between the outer lens 21 and the inner lens 22 and clamped by the humidity control element 111 by the outer lens 21 and the inner lens 22, so that the humidity control element 111 does not image the light path in the optical lens module 20, and the optical processing device can maintain its effect and reduce the influence of water mist on the optical processing device, so that the optical processing device can work well and stably.
The humidity adjusting element 111 can be disposed at the connection position of the inner lens 22 and the outer lens 21, the air between the inner lens 22 and the outer lens 21 flows through the circulation groove 1121 to the external space, when the humidity in the air is high, the humidity adjusting element 111 absorbs part of the moisture to adjust the amount of the moisture in the environment, so that the humidity adjusting element 111 realizes the consumption of the moisture in the air. In addition, when the external humidity is high, the accommodating space 100 is prevented from being filled with more water vapor by the external air, and the lens atomization problem of the optical processing device is effectively prevented.
It should be noted that the optical lens 40 can be applied to a device selected from the following group: laser detection device, projection arrangement, on-vehicle head-up display device (HUD). And is not limited in any way in the present invention.

Preferably, the supporting members 112 are embodied in at least three such that at least one conditioning element 111 can be accommodated in the flow-through channel 1121. When the humidity control elements 111 are disposed in the respective circulation grooves 1121, and each humidity control element 111 is disposed in the respective circulation groove 1121, the number of the humidity control elements 111 is less than that of the respective circulation grooves 1121, so that the circulation grooves 1121 promote air circulation, and simultaneously increase the humidity control of the humidity control elements 111 and reduce the water mist on the lens surfaces of the outer lenses 21 and the inner lenses 22.
Alternatively, the humidity control element 111 may completely fill the flow-through groove 1121 in order to optimize the humidity control effect of the humidity control carrier 11.
Preferably, the number of the circulation grooves 1121 is 8, the humidity control elements 111 are four, and the circulation grooves 1121 are filled at intervals, so that when the humidity control elements 111 are accommodated in the circulation grooves 1121, the humidity control elements 111 can regulate moisture in air, the circulation grooves 1121, which are not filled with the humidity control elements, promote air circulation between the accommodating space 100 and an external space, further accelerate the adjustment of humidity of air entering the accommodating space 100, prevent the optical lens module 20 from generating water mist, and further quickly dissipate the water mist on the lens surface of the optical lens module 20.

(g21) each of the humidity control elements 111 is provided at intervals to the flow channel 1121.
Referring to fig. 6A to 6B, a fifth preferred embodiment of the invention is disclosed and explained in detail, wherein the wet control carrying part 11 of the optical processing apparatus of the present invention is different from the wet control carrying part 11 of the optical processing apparatus of the third preferred embodiment in the implementation manner, and becomes a new embodiment. The humidity control carrier 11 includes the support member 112 and one humidity control element 111, wherein the humidity control element 111 is disposed in the gap between the inner lens 22 and the support member 112, so that the humidity control element 111 can better regulate the humidity of the accommodating space 100 therein. Since the humidity of the area where the optical lens 40 is assembled is different from the humidity of the area where the optical lens 40 is used. The humidity environment of the optical lens 40 needs to be considered during the manufacturing and selling of the optical lens.
When the optical lens 40 is in an environment with high humidity in the preparation process and the optical lens 40 is in an environment with low humidity in the use process, after the processing module 30 works to generate heat, the water vapor inside the optical lens 40 is attached to the inner lens 22 after being liquefied by the inner lens 22, the air in the accommodating space 100 inside the optical lens 40 is slower in circulation with the external space, and the water vapor inside the accommodating space 100 is difficult to circulate to the external space, so that the optical lens 40 cannot be stably used. In contrast, the humidity control element 111 according to the fifth preferred embodiment of the present invention is disposed between the inner lens 22 and the lens barrel 20, so that the humidity control element 111 can adjust the humidity of the accommodating space 100 therein.
The humidity control element 111 is made of a humidity control material, so that a certain preset humidity is maintained in the environment, and the humidity of the environment can be adjusted to the certain preset humidity instead of only absorbing moisture under the condition that the humidity of the environment is insufficient.
Preferably, the support member 112 has a locating shelf 1125, wherein the locating shelf 1125 is defined by the interior sidewalls of the interior wall 1122 of the support member 112. The positioning platform 1125 is connected to the accommodating space 100, so that the inner lens 22 can be supported and limited by the positioning platform 1125 when being inserted into the accommodating space 100 from the first light-passing opening 101.
It is worth mentioning that the humidity adjusting element 111 is disposed on the positioning platform 1125 and is clamped between the positioning platform 1125 and the inner lens 22. That is to say, the humidity adjusting element 111 is disposed between the lens barrel 20 and the inner lens 22 to maintain the accommodating space 100 at a certain humidity, so that when the water vapor in the accommodating space 100 is high, the water mist attached to the inner lens 22 when cooled can be dissipated quickly.
Further, the inner wall 1122 and the outer wall 1123 protrude from the positioning platform 1125, so that the inner lens 22 is placed in the accommodating space 100 through the first light passing port 101, and the inner lens 22 is limited by the positioning platform 1125.

The humidity adjusting element 111 is disposed around the positioning table 1125 with less space for communication between the supporting member 112 and the inner lens 22, so as to allow the accommodating space 100 inside the inner lens 22 to communicate with the accommodating space 100 on the object side of the inner lens 22, thereby preventing the moisture in the accommodating space 100 from being unable to escape.
Preferably, the humidity control element 111 is an annular body, wherein the humidity control element 111 is fittingly disposed on the positioning platform 1125 and is limited by the positioning platform 1125, so that after the inner lens 22 is inserted into the accommodating space 100 from the first light passage 101, the inner lens 22 is limited to the rear side by being blocked by the humidity control element 111, and after the outer lens 21 is covered on the lens barrel 10, the outer lens 21 is clamped by the outer lens 21 and the lens barrel 10, so as to stably accommodate the inner lens 21.

The support member 112 of the moisture control carrier 11 has a positioning slot 1126 and the positioning platform 1125, wherein the positioning slot 1126 is formed inside the positioning platform 1125. That is, the positioning slot 1126 is defined by the positioning platform 1125 and the inner wall 1122.
Preferably, the positioning slot 1126 presents an annular groove. The humidity adjusting element 111 is disposed in the positioning groove 1126, so that when the inner lens 22 is retained on the positioning platform 1125, the humidity adjusting element 111 is retained by the inner lens 22 and the supporting member 112, so as to adjust the humidity of the accommodating space 100, and dissipate the water mist formed in the accommodating space 100 as soon as possible. Further, the humidity adjusting element 111 is positionally accommodated in the positioning table 1125, and is kept to be conductively accommodated in the positioning slot 1126, and the humidity adjusting element 111 is arranged in the gap between the inner lens 22 and the positioning slot 1126.
Preferably, the positioning slot 1126 is implemented as an annular groove.
Preferably, the number of the humidity control elements 111 is at least two, and the humidity control elements 111 are implemented as block-shaped bodies. The humidity conditioning elements 111 are sequentially placed in the positioning slot 1126, and the humidity conditioning elements 111 are confined to the annular groove.
Preferably, the number of the humidity control elements 111 is three. The humidity control element 111 is disposed in the positioning groove 1126. Further, the positioning groove 1126 has a certain space for allowing air to flow therethrough, so as to facilitate the air flow between the accommodating space 100 inside the inner lens 22 and the accommodating space 100 on the object side of the inner lens 22, so as to improve the water vapor dissipation of the accommodating space 100, and further improve the water mist dissipation effect of the accommodating space.
Preferably, three conditioning elements 111 are provided.
Alternatively, the humidity controlling element 111 may be fixedly positioned at each position of the positioning slot 1126 by gluing or the like.
Optionally, the positioning slot 1126 is implemented as a plurality of grooves arranged in the positioning platform 1125. That is to say, the number of the humidity adjusting elements 111 is at least two, and each humidity adjusting element 111 is respectively placed in one of the positioning slots 1126 to adjust the humidity of the accommodating space 100 and dissipate the water mist as soon as possible. The larger the number of the humidity control elements 111, the better. That is, the positioning groove 1126 may be alternatively implemented to be sequentially arranged in succession in a ring shape.
It should be noted that the inner wall 1122 and the outer wall 1123 protrude from the positioning platform 1125, so that the inner lens 22 is placed in the accommodating space 100 through the first light passing port 101, and the inner lens 22 is limited by the positioning platform 1125.
Since the inner lens 22 is disposed in the lens barrel 10 in a limited manner, and the air in the accommodating space 100 flows relatively low, that is, the flow rate of the water vapor in the accommodating space 100 inside the inner lens 22 flowing to the external space is very poor, if the air in the accommodating space 100 inside has relatively large water vapor, it is difficult to dissipate the water vapor quickly, and the humidity adjusting element 111 disposed in the inner lens 22 and the positioning table 1125 can dissipate the water vapor in the accommodating space 100 quickly, so that the accommodating space 100 prevents the formation of water mist and can dissipate the water mist in the accommodating space 100 quickly.
Preferably, the humidity adjusting element 111 can rapidly dissipate more than 95% of the water mist in a short time, so as to adjust the humidity of the accommodating space by the humidity adjusting element 111.
It will be understood and appreciated by those skilled in the art that the humidity conditioning element 111 can be disposed at multiple locations on the supporting member 112, so that the moisture in the accommodating space 100 can be dissipated more quickly. Since the greater the area and number of the humidity control elements 111, the better the dispersion of moisture in the storage space 100, the humidity control effect can be effectively improved by providing the humidity control elements 111 at a plurality of positions on the support member 112.
