The vacuum assembling apparatus comprises a lens holder (1), a spacer ring (2), a vacuum adsorption bracket (5), a burst resisting hose (6), a valve (7), a vacuum vessel (8), a manometer (9), and a vacuum pump (10). The eyeglass (3) and the adsorption bracket (5) are adsorbed together by using the vacuum adsorption, and the eyeglass is assembled into a mechanical shell (4) from top to bottom. The vacuum assembling apparatus has the advantages of wide using range and high accuracy, raising assembling efficiency greatly, meanwhile reducing pollution and improving the imaging quality of the lens.
Description
Technical field: the vacuum assembling device of this utility model optics, belong to the assembly system of optical precision instrument, the optics that specifically is applied in fields such as precision measurement, photograph, duplicating, laser technology and Precision Machining is in addition in the assembly work of parts.
Background technology: the dress school of optics (such as optical lens), be meeting design requirement, process qualified optical component and component of machine and be combined into a complete camera lens, it is as last procedure of optical lens production and processing, because the specific (special) requirements on the optical quality, it is that strictness is meticulous again that assembly work is become, and the quality of assembly work often directly influences the quality of optical imaging of whole camera lens.
The assembly method of optical lens is seen figure one in the prior art, at first has a camera lens holder 1, and interval turns 2 and eyeglass 3 are placed in the camera lens holder 1 by direction, and the mechanical cover 4 with optical lens is inserted in from the top down then, even if form a complete optical lens.Shown in figure two.
If camera lens, optical design becomes three optical mirror slips, so just three optical mirror slips and the interval turns between them are placed in the camera lens holder simultaneously, and whether the interval of measuring between eyeglass and the eyeglass meets the optical design requirement, as do not meet, carry out the reconditioning of interval turns, make it not meet the optical design requirement, at last eyeglass and interval turns and camera lens shell are cleaned, again with direction eyeglass and interval turns are placed on Jing Tuoshang in order by above-mentioned steps, then camera lens machinery shell is inserted in from top to bottom, the camera lens that installs is turned, press trim ring, camera lens just assembling is over, enter the optical check stage of camera lens at last, check whether meet the optical design requirement.
In recent years along with optical technology constantly develops, the optical instrument of some specific (special) requirements is more and more, camera lens is also done littler and littler, the diameter of lens that has even little below 5mm, this results in hand cramps and difficulty just for the optical lens assembly work, the tradition assembly method is difficult to finish the fittage of camera lens, its reason is that the optic diameter of tiny lens is smaller, and thickness is relatively more broad, and therefore little eyeglass weight is also low weight, these little eyeglasses and little spacer ring all are placed on Jing Tuoshang, be inserted in from top to bottom with the camera lens mechanical cover, as long as one bump gently, or a contact, variation has just taken place in the position of little eyeglass and booth circle, camera lens mechanical cover be difficult to pack into little eyeglass and closely-spaced circle, even can bump little eyeglass and booth circle or block, cause and collapse the limit, need processing again, usually needing repeated multiple times to assemble could success.Whenever once just need clean once repeatedly, waste time and energy like this little eyeglass of optics and closely-spaced circle, repeatable operation, even can cause rete to damage, influence the optical lens image quality.
Summary of the invention: for solving contradiction and the problem that above assembling micro-optics parts occur, we develop the vacuum assembling device of an optics.Its principle of work is to utilize the vacuum suction effect to replace manual operations, is characterized in applied widely, and the degree of accuracy height can be used for assembling the different optics of size specification, is particularly useful for the work of debuging of micro-optics parts.
Technical scheme: ask for an interview figure three, the concrete structure of the vacuum assembling device of this optics comprises camera lens holder 1 and interval turns 2, it is characterized in that it also comprises vacuum pump 10, tensimeter 9 on the vacuum tank, vacuum tank 8, valve 7, high-pressure rubber pipe 6 and vacuum suction carriage 5; Annexation between each parts is: vacuum pump 10 links to each other in vacuum tank 8 by high-pressure rubber pipe 6, tensimeter 9 is housed on the vacuum tank 8, vacuum tank 8 is connected with vacuum suction carriage 5 by high-pressure rubber pipe 6, and absorption carriage 5 is adsorbing eyeglass 3, in the mechanical cover 4 of from top to bottom packing into.
According to the various opticses of different size and shape, make several a series of absorption carriages 5 respectively, interval turns 2 and camera lens holder 1, standby as annex;
The concrete course of work is: vacuum pump vacuumizes vacuum tank, the logical high-pressure rubber pipe of vacuum tank connects the vacuum suction carriage, eyeglass and vacuum suction surface are the smooth surfaces of making by Precision Machining, the attached bracket surface of suction of taking seriously contacts with eyeglass one, open and vacuumize valve, because the effect that vacuumizes, absorption carriage and eyeglass surface of contact form a negative pressure, the eyeglass another side forms malleation, and eyeglass is because the effect of positive and negative pressure is attached together eyeglass and absorption carriage securely like this.In the time of needs assembling camera lens, the eyeglass that will adorn by vacuum absorption device is adsorbed on the absorption carriage securely, holding the absorption carriage that is connected flexible pipe down assembles from camera lens machinery shell top, adorn an eyeglass and put an airspace circle, the eyeglass of different-diameter can be very easy to the small camera lens of assembling like this with the absorption carriage and the interval turns of different sizes.
The beneficial effect of the vacuum assembling device of optics: this device is reasonable in design, simple in structure, with low cost, easy to use, and effect is remarkable; Have the following advantages:
One, usable range is wide, the efficiency of assembling height: this device is not only applicable to the micro-optics parts, is applicable to general optics and cut, and is usually used in the 4-20mm optics.As long as once dress is slightly measured interval between the eyeglass according to the interval turns between the good eyeglass of designing requirement reconditioning, just last assembly work can have been entered, and traditional assembly method, need repeated multiple times assemble the fittage that just can finish camera lens, therefore, efficiency of assembling improves more than three times.
They are two years old, easy to use, safe and reliable: the optical mirror slip of small optics is smaller and thinner, remove to take its damage and pollution optical mirror slip easily with instrument and hand, might cause eyeglass to collapse the limit by traditional assembly method, safer with the vacuum suction optical mirror slip, in assembling process, can not produce the mutual friction of eyeglass and camera lens spacer ring and cause eyeglass and rete to damage.
They are three years old, prevent to pollute, improve image quality: very clean with this device assembling optics, and the optical mirror slip of micro-optics parts is smaller, the dust of camera lens and contamination particle directly influence image quality, and the cleaning of little eyeglass is the work that bothers very much, be difficult to give the pollution of dust protection and to the damage of optical mirror slip with traditional assembly method, dust and little particle all can be adsorbed to fall with vacuum absorption device assembling tiny lens, owing to saved the process of assembling repeatedly, the pollution number of times of eyeglass reduces, and keeps mirror surface cleaning, has improved the image quality of camera lens.
