Abstract
Compare and manage the utility model discloses a kind of sealing cap centering, it includes comparing tube body, offer mutually concentric first on the comparison tube body successively from the outside to the core and compare device to hole than device to hole and second, described first matches than the inner surface of device to hole and the base periphery of photodiode, the base of the photodiode is provided with chip, the exiting surface of the chip is mutually concentric with the base, and the outside of the chip is also arranged with lens hood, the periphery of the lens hood matches with described second than device to hole.The utility model compares device to hole by opening up mutually concentric first successively from the outside to the core on tube body is compared than device to hole and second, the base of photodiode and the concentricity of lens hood are detected than device to hole than device to hole and second using first, and the exiting surface of chip and base is mutual concentric, so as to converse the concentricity of lens hood and chip, it is not only simple in structure, the easy to use and large batch of sampling observation that can be adapted to.
Description
Technical field
The utility model is related to photodiode technologies field, more particularly to a kind of sealing cap centering compares pipe.
Background technology
Existing photodiode when encapsulating sealing cap, it is necessary to ensure lens hood and chip with one heart in ± 30um, still, mesh
Preceding detection tool construction is complicated, using cumbersome and efficiency is low, is not suitable for large batch of sampling observation.
Utility model content
The utility model is mainly the technical problem solved in the presence of prior art, thus provide it is a kind of it is simple in construction,
The sealing cap centering of easy to use, suitable large batch of sampling observation compares pipe.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：
The sealing cap centering that the utility model is provided compares pipe, and it is included comparing on tube body, the comparison tube body from outer
Mutually concentric first is inwardly offered successively than device to hole and second than device to hole, described first than device to hole inner surface and photoelectricity two
The base periphery of pole pipe matches, and the base of the photodiode is provided with chip, the exiting surface of the chip with it is described
Base is mutually concentric, and the outside of the chip is also arranged with lens hood, and the periphery of the lens hood is compared with described second
Hole matches.
Further, described first than device to hole depth be equal to the base thickness.
Further, described second than device to hole depth be more than the lens hood height.
Further, the comparison tube body is made using transparent material.
The beneficial effects of the utility model are：By opening up mutually concentric successively from the outside to the core on tube body is compared
First than device to hole and second than device to hole, using first than device to hole and second than device to hole to the base of photodiode and lens hood
Concentricity detected, and the exiting surface of chip and base is mutual concentric, so as to converse the same of lens hood and chip
Heart degree, it is not only simple in structure, the easy to use and large batch of sampling observation that can be adapted to.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the accompanying drawing used required in description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the use state figure that sealing cap centering of the present utility model compares pipe；
Fig. 2 is the structural representation that sealing cap centering of the present utility model compares pipe.
Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that advantage of the present utility model
It can be easier to be readily appreciated by one skilled in the art with feature, so as to make protection domain of the present utility model apparent clear and definite
Define.
Refering to shown in Fig. 1-2, sealing cap centering of the present utility model compares pipe, and it includes comparing tube body 1, compares tube body
Mutually concentric first is offered on 1 successively from the outside to the core than device to hole 2 and second than device to hole 3, first than device to hole 2 inner surface with
The periphery of base 5 of photodiode 4 matches, and the base 5 of photodiode 4 is provided with chip 6, the exiting surface of chip 6 with
Mutually with one heart, and the outside of chip 6 is also arranged with lens hood 7 to base 5, the periphery of lens hood 7 and second than device to hole 3 interior table
Face matches.
The utility model by opening up mutually concentric first than the He of device to hole 2 successively from the outside to the core on tube body 1 is compared
Second than device to hole 3, using first than device to hole 2 and second than device to hole 3 to the base 5 of photodiode 4 and the concentricity of lens hood 7
Detected, and the exiting surface of chip 6 and base 5 is mutual concentric, so as to converse the concentric of lens hood 7 and chip 6
Degree, it is not only simple in structure, the easy to use and large batch of sampling observation that can be adapted to.
It is preferred that first than device to hole 2 depth be equal to base 5 thickness, in detection process, by observing base 5
Whether bottom is with comparing whether the bottom of tube body 1 flushes, so that it may qualified to the thickness of base 5 tentatively to be judged, so as to carry
The product quality detection efficiency and effect of photodiode 4 are risen.
In this implementation, in order to avoid second interferences than the bottom of device to hole 3 with lens hood 7, second is bigger than the depth of device to hole 3
In the height of lens hood 7.
Preferably, for convenience observation photodiode 4 first than device to hole 2 and second than the state in device to hole 3, compare
Tube body 1 is made using transparent material.
More than, embodiment only of the present utility model, but protection domain of the present utility model is not limited thereto,
Any change or replacement expected without creative work, should all cover within protection domain of the present utility model.Therefore,
Protection domain of the present utility model should be determined by the scope of protection defined in the claims.
