Implement optimal mode of the present invention
Fig. 1 shows and presents to the medical worker for the endoscope 10 that uses.This endoscope 10 extends between far-end 11 and near-end 12, and this far-end 11 is that this near-end 12 is from the nearest end of people that uses this device from the nearest end of object that will imaging.This view shows the optical body 13 with eyecup 14, and the individual observes image by this eyecup 14.Thereby fiber pole 15 is held out splice going splice from light source and is provided for light through the optical fiber transmission, in order to just to illuminate the object in imaging.In this certain embodiments, device axis 18 is optical axises.
The 22 dislocation Liars 31 closely along axis 18 from window.As everyone knows, the object that is positioned on the extended line of optical axis 18 of 31 pairs of Liars forms image.Liar 31 can have any embodiment in the various embodiments.
The eyepiece 32 of optical devices 20 extends in the tubulose epitheca 21 from near-end 12.The axially extended axle collar 33 is welded or is brazed on the tubulose epitheca 21.The optical element that forms eyepiece can comprise some combination of aperture/sept, eye lens or guard ring or these elements or other optical element.Eyepiece 32 is to be an example of the optical element of the optical viewing arrangement of human eye or other form more well known in the prior art such as video observation system transmitted image.
The 3rd optical elements sets forms relay lens system 41 between Liar 31 and eyepiece 32.As everyone knows, this relay lens system is passed to eyepiece 32 with image from Liar 31.First sept 42 positions with respect to 31 pairs first relay lens elements of Liar such as doublet lens 43.In this specific embodiment, middle cylindrical optic lens sept 44 and other relaying doublet lens 43 constitute the other optical element of separating in order along optical axis 18, Duan relaying doublet lens 45 up to date, promptly nearest relaying doublet lens 45 with near-end 12.The structure of these relay lens system known in the state of the art and operation.Can make many improvement to specific lens shown in Figure 2 and sept structure.
Fig. 3 is the sections of optical devices 20 along the whole axis 18 among Fig. 2; Fig. 4 is perpendicular to the section of axis 18 by Fig. 3.Fig. 3 and Fig. 4 show by sept 44 along axis 18 separated two doublet lens 43.Each doublet lens 43 has first and second 45 and 46 and middle outer fringe surface 47.Tubulose epitheca 21 these optical elements of supporting.According to the present invention, only in construction process, use sept 44.Because behind utilization the present invention, sept 44 is not carried out the function of main location, this sept 44 can be thinner than traditional sept.
In fact, the invention reside in by engaging each lens or other optical element are positioned, thereby each such optical element is carried out lock-bit along axis 18 with near one or two face 45 and 46 outer fringe surface 47 of optical element.Can adopt different detailed processes.For example, Fig. 5 shows the hydrostatic pressure process 50 that adopts hydrostatic pressure equipment 51 shown in Figure 6 and implement.More specifically, in Fig. 5, the various operations of step 52 representative by these operations, are assembled optical devices 20 for example shown in Figure 3 with lens, sept and other optical element in tubulose epitheca 21.After the assembling, in step 53 optical devices 20 are positioned in the pressure chamber 54, this pressure chamber 54 is expressed as the cylindrical structural of the sealing with gland bonnet 55 in Fig. 6.
Along with removing gland bonnet 55, supporting construction 56 is connected to the end of optical devices 20, and this supporting construction 56 drops in the hydraulic oil 57.After gland bonnet 55 replaced, the operation of step 61 control hydraulic pump 61 and with boost in pressure to making epitheca 21 that the degree of plastic yield take place.Pressure gauge 62 these pressure of monitoring.Reduction valve 63 prevents that pressure is excessive, and plays the effect of snap-out release pressure when process finishes.When reaching suitable pressure, the part in the middle of lens element of tubulose epitheca 21 deforms, with the part that covers lens face for example on the lens face 45 and 46 among Fig. 3, and lock-bit and pinning lens element.This distortion makes these parts of epitheca 21 limit the axially-movable of lens 43 in epitheca 21 with showing in the geometric configuration one of near the face outer fringe surface 47 45 and 46.With reference to figure 7 and 8, by medium 57 hydrostatic pressure is applied to the outside of optical devices 20, it is avette that the not supply section distortion between lens element 43 of tubulose epitheca 21 is become, and this is avette to have the part 64 and 65 that keeps flat along main axis.Lens element 43 prevents the adjacent part distortion of tubulose epitheca 21.Thereby tubulose epitheca 21 covers on two lens faces 45 and 46 at each lens element place, as the covering at 66 and 67 places on each lens element 43 of lens element 43.Produce thereupon to the transition piece of covering 66 and 67 with lens element 43 locks in place, thereby lens element is fixedly positioning in tubulose epitheca 21 along axis 18.If adopt sept 44, then this sept 44 is thin septs, and this sept 44 is deformed into consistent with tubulose epitheca 21.Other covering is provided like this.
After distortion takes place,, in the step 70 of Fig. 5, start reduction valve 63 among Fig. 6 with relief pressure as showing ground by reaching predetermined pressure.After this, can remove end cap 55, and from chamber 54, remove out the optical devices 20 of the structure of Fig. 7 and 8.
In this process, the component of elasticity of the circumference under the given hydrostatic pressure or hoop compressive stress and radial deflection can be used for calculating and the pressure when predicting for certain material and material thickness generation plastic yield.Having adopted the pressure of 1450 to 2250 PSI that diameter is provided is the suitable plastic yield of 3 millimeters 316 stainless-steel tubes.Foundation or prediction cause that for other material, material thickness and diameter the step of the pressure of plastic yield is known by the those of ordinary skill in the present technique field.
The major control criterion that is used for this process is to produce enough pressure to make the part of crossing a part of lens face of housing to keep the mode plastic yield of pipe integrality.This method and control criterion can be suitable for all types of optical devices, comprise that those bear optical devices high pressure steam sterilization or other severe rugged environment, the needs sealing.In addition, should limit radial deformation, make the crushed element of tubulose epitheca 21 not extend to the visual field that is used for optical devices 20.
Fig. 9 to 11 shows the replacement process of aforesaid fluid static pressure process, and this replacement process adopts series to press the pleat process.Initial step 80 for example is included in and uses lens, sept, prism, window and other optical element construction of optical device 20 in the housing shown in Fig. 3 and 4.Step 81 make optical devices 20 by the pressure pleat instrument place of arrow 82 representatives with as first lens of selected lens first in the face of neat.In this case, select lens 83, and first 84 is alignd with pressure pleat instrument 82 as doublet lens 43.At step 85 place, the pleat instrument is pressed in utilization in the transverse plane of axis 18, is to form gauffer on the opposite side of housing of form thereby be in tubulose epitheca 21 at the end sections 86 of sept 43.In step 87, with optical devices 20 with press the pleat instrument to reorientate, make and press second 97 of pleat instrument and selected lens to align, promptly be positioned at the position of arrow 90 representatives.Step 91 repeats this pressure pleat process then.
If optical devices 20 comprise other lens, step 92 is diverted to step 93 with control, presses facing of pleat instrument and next lens neat thereby make, and these next one lens are represented by arrow 94 as selected lens and at Figure 10.Control is turned back to step 85,87 and 91 and produces first gauffer and produce second gauffer in the position of arrow 95 with the position at arrow 94 then.When finishing this process, just finished described process and step 92 and be diverted to and finish this series at step 96 place and press the pleat process for each lens element.
The pressure pleat at step 85 and 86 places usually occurs in opposed position on the diametric(al).Step 85 and 86 can also be included in the repeatedly pressure pleat operation of each aligned position.For example, first presses the pleat operation can produce the gauffer of vertical alignment, and second press the pleat operation can produce and first gauffer gauffer of displacement at an angle of 90.Can adopt more other pressure pleat instrument or processing to produce suitable gauffer by serial or parallel, as the gauffer that can obtain by special pressure pleat instrument, this special pressure pleat instrument can produce the radial pressure that equates from a plurality of radial angles.
Figure 11 shows has four opposed gauffer part 100 and 101 optical devices 20 on diametric(al), and these gauffer parts 100 and 101 manually press the pleat operation to produce by twice.Also as illustrating especially among Figure 10, if adopt sept 43 to be used for initial alignment, each fold place that these septs 43 also will be in these gauffers is the gauffer in Figure 11 100 and 101 place's deflections for example.
Control the gauffer that each presses the pleat operation to have a degree of depth with generation, this degree of depth guarantees that gauffer partly covers on the part of lens face such as lens face 84.Yet, thereby should limit gauffer so that do not make material breaks keep the integrality of any hermetically-sealed construction.Also gauffer should be limited so that structure does not extend in the visual field.No matter in which kind of is arranged, these gauffers all make housing or tubulose epitheca with near the outer fringe surface of each doublet lens 83 first and second to look like face 84 and 97 consistent, with along axis 18 pinning doublet lens 83.
That Figure 12 to 14 shows the like configurations that is used to produce shown in Figure 10 and 11 but need not the structure of sept 44.According to present embodiment, the process 110 of Figure 12 starts from the end with optical devices 20 in the step 111, and to be fixed on tubulose epitheca 21 be in the far-end of housing of form.For example, assemble this structure if insert device, by objective lens arrangement being positioned and performing step 111 at far-end by near-end from endoscope.
The step 112 tubulose epitheca 21 that aligns in the axial direction then makes position as the distal face of first lens of selected lens be positioned at and presses pleat instrument place.This is by 113 representatives of the arrow among Figure 13.In step 114, the operation of the pressure pleat of one or many produces the gauffer part, and these gauffers partly make the part of tubulose epitheca 21 consistent with selected lens at far-end lens face place.
In step 115, with the lens position instrument lens element such as lens element 116 are inserted in the tubulose epitheca usually.This lens element that moves forward contacts with the housing parts 120 of pressing pleat up to far-end lens face 117.
Step 121 is reorientated tubulose epitheca 21 in the axial direction then, with the proximal end face 122 at the lens 116 that align as the pressure pleat instrument place of arrow 123 representatives.At step 124 place, another presses the pleat operation to make the part conformal at near-end lens face place of tubulose epitheca 21 is gauffer 125.In step 126, can remove any orientation tool that adopts in the step 115.Thereby lens 116 accurately are held in place on the optical axis 18 and are vertical with axis 18.
Figure 13 shows another lens element 127 with far-end lens face 128 and near-end lens face 129.Thereby the step 130 among Figure 12 turns to step 131 with control, and this step 131 location tubulose epitheca 21 is with by the pressure pleat instrument place alignment of the arrow 131 representatives distal face as next lens of selected lens.Control is turned back to step 114 to form initial gauffer 133 then, can adopt orientation tool to contact with gauffer 133 up to distal face 128 to insert lens 127 thereafter.Can will press the pleat instrument be repositioned to position corresponding to arrow 134 then to produce gauffer at near-end lens face 129 places.
According to step 114 to 126 during with all lens element location, step 130 is diverted to step 137 place terminating operation with control.
According to present embodiment, aforementioned operation produces four gauffers of separating around the circumference equal angles of tubulose epitheca 21 at each lens face place.Figure 14 shows opposed first gauffer 133 on diametric(al) especially, and this gauffer 133 engages with the distal face 128 of lens 127.Second presses pleat to be operable to is created in opposed gauffer 136 on the diametric(al) squarely.
Fig. 3 shows each parting 34 wherein and bears against optical devices 20 on the opposed lens face.Figure 15 shows the replacement method, plays the effect of optical branch support arrangement and at pre-position supporting lens element by each lens sept of this replacement method.For example, Figure 15 shows the lens element 140 with first and second lens faces 141 and 142.Sept 143 supportings are as the lens element 140 of sub-component or lens subassembly.In this application-specific, at lens element in sept 143 after the axial location, press the pleat operation to produce gauffer group 144 and 145, thereby in sept 143, pin lens element 140, middle ware parting part 146 between gauffer 144 and 145 engages with the outer fringe surface 147 of lens element 140, and should press pleat operation generation component 148.Thereby the structure of optical sub-assembly as shown in figure 16 such as sub-component 144 comprises: adopt tubulose epitheca such as tubulose epitheca 21; And after with end member such as object lens location, in the assembly with suitable dimension shown in Figure 15 such as assembly 148A and 148B tubular stinger successively, to produce relay lens system.Can adopt the method among Figure 15 to be used for relay lens system, but obviously can adopt this method to be used to form object lens or formation eyepiece.
Shown in Fig. 9 to 14 each is pressed pleat action need some control, the particularly degree of depth of each gauffer.Mechanical stop on the instrument can provide this control.Those of ordinary skill in the present technique field is known the operation and the control of this process very much.
Figure 17 to 19 shows combining of another other form optical devices of the present invention, and these optical devices are suitable for endoscope without difficulty, endoscope that particularly can high pressure steam sterilization.As shown in these figures, optical module 150 extends along device axis 18, and this device axis 18 is an optical axis in this certain embodiments.Assembly 150 comprises optical element 151 and the conformal pipe 152 that optical element 151 is positioned.For the reason that illustrates, the optical element 151 among Figure 17 to 19 is the doublet lens with lens 151A and 151B.Conformal pipe 152 comprises two shell 152A and 152B.
Be specifically related to shell 152A, center section 153 in the axial direction with optical element 151 with prolonging, and have around axis 18 and make a part of consistent radius of center section 153 and optical element 151.Each extension 154 and 155 has the radius that reduces slightly to produce radial transition parts 156 and 157 with center section 153 respectively.These transition pieces 156 and 157 and the outward flange of optical element 151 overlapping, thereby by being consistent, and in sub-component 150, produce reliable axial location with near the face outer fringe surface 162 160 of optical element 151 and 161 geometric configuration.
Each shell among shell 152A and the 152B has the excircle that is used for cylindrical lens group 151, and this excircle makes to have gap 163 and 164 between shell 152A and 152B less than the semi-circumference of lens combination 151.Thereby assembly shown in Figure 19 150 can be slid into external structure for example in the tubulose epitheca 21 among Figure 17 and 18.The external diameter of center section 153 makes that corresponding to the internal diameter of epitheca 21 assembly 150 slides in assembling in epitheca 21.The cooperation of assembly 150 in epitheca 21 produces enough frictions with the unnecessary axial displacement in preventing to use.Thereby epitheca 21 also prevents any outside radial displacement of shell 152A and 152B.In addition, the axial range of center section 153 enough is used for preventing assembly 150 deflection in tubulose epitheca 21.
Be easy to make conformal pipe 152 by many different manufacture processes.For example, in having the smart mould machine that cooperates smart mould, each shell in these shells such as shell 152A can form required profile by foil.Other method is that this deformable material is used for and described chip bonding in conjunction with single accurate machine mould and the pressing element with deformable material.Also in other method, can in smart molded tool, form shell such as shell 152A in the shell, lens combination such as optical element 151 are carried in the conformal shell 152A, and exert pressure, thereby around optical element 151, form another foil by pressing element with deformable material such as RTV.
The conformal tube side method of describing with reference to Figure 17 to 19 has many advantages.Need not just can assemble these conformal pipes 152, and be accompanied by the difficulty that keeps clean along the tube wall single lens that slide along the tube wall single lens that slide.Adopt these conformal pipes 152 bigger productive capacity can also be provided, reduce cost and improve the precision of axial location.And this structure is compatible with automation equipment.
Disclosed is some alternative methods that are used to form optical devices, axially accurately is provided with optical element in these optical devices with placing.These different structures are characterised in that pressure pleat or the crushed element with support member, and these press the part of pleat or crushed element and each face of optical element overlapping to carry out lock-bit at support member interior focusing element.The example of the process that adopts hydrostatic pressure process, traditional pressure pleat and process operation is disclosed.These only are the modes of example.Obviously can not depart from the present invention disclosed equipment is made many improvement.Thereby the purpose of claims is to cover all these variations and improvement that occurred in true spirit of the present invention and the scope.
