Abstract
The present invention is the identification method of biconvex non-spherical lens directionality, comprising the following steps: (1) die surface increases loop design, and raw material are formed to obtain the biconvex non-spherical lens with annular ditch groove by mold microdiecast；(2) have the one side of annular ditch groove as main reference plane biconvex non-spherical lens, carry out filming process and cutting action；(3) lens are cleaned, after the completion, arrow logo is completed by marking pen according to the label of annular ditch groove under the microscope, with display assembling datum level and assembly orientation.The present invention can carry out directionality differentiation by the design of ring-shaped groove, and specific cutting mode and arrow logo to lens, and the direction positioning accuracy of significantly high client improves production efficiency, reduce the pollution waste and damage of lens.
Description
Technical field
The present invention relates to optical fields, more particularly to the identification method of biconvex non-spherical lens directionality.
Background technique
In optical communication industry, due to the topology requirement by product small, the size of camera lens is required more next
It is smaller, it is more and more accurate, while maximumlly being required to meet clear aperature size again, it needs to carry out two to the shape of camera lens
Secondary processing.And the direction recognition as conventional aspherical coupled lens, be all with the naked eye differentiated under the microscope, or
It is differentiated in client by speckle analysis equipment, so that client is increased using difficulty, and extends its process time.
Therefore it is directed to biconvex non-spherical lens, the difference of two curved surfaces is difficult to the case where differentiating under the microscope in appearance, makes
Inaccurate at the direction positioning of client, production efficiency is low, increases the pollution waste and damage of lens.
Summary of the invention
The object of the present invention is to provide the mark sides of a kind of delicate structure, the biconvex non-spherical lens directionality of good heat dissipation
Method.
The present invention is achieved through the following technical solutions above-mentioned purpose: the identification method of biconvex non-spherical lens directionality, packet
Include following steps:
(1) die surface increases loop design, and raw material are formed to obtain with annular ditch groove by mold microdiecast
Biconvex non-spherical lens；
(2) have the one side of annular ditch groove as main reference plane biconvex non-spherical lens, carry out filming process and cut
Cut process；
(3) lens are cleaned, after the completion, arrow is completed by marking pen according to the label of annular ditch groove under the microscope
Leader is known, with display assembling datum level and assembly orientation.
Further, the cutting processing path in the cutting action is rectangle, the both ends of the rectangular short side
Point is respectively positioned in ringed line, and two-end-point one of rectangular long side is located in ringed line, another is located at outside ringed line, is cut
Complete there will be annular ditch groove there are two the retention of the single side at angle on four angles of rear lens；
Further, the cutting mode is diamond dust cutting.
Compared with prior art, the beneficial effect of the identification method of biconvex non-spherical lens directionality of the present invention is: passing through
The design of ring-shaped groove, and specific cutting mode and arrow logo can carry out directionality differentiation to lens, significantly high
The direction positioning accuracy of client improves production efficiency, reduces the pollution waste and damage of lens.

Fig. 3 is the schematic diagram in cutting processing path.
Fig. 4 is the lens schematic diagram after cutting.
Fig. 5 is the left view of Fig. 4.
Fig. 6 is the schematic diagram that lens in Fig. 4 have increased arrow logo.
Specific embodiment
Please refer to Fig. 1 to Fig. 6, the identification method of biconvex non-spherical lens directionality, comprising the following steps:
(1) die surface increases loop design, and raw material are formed to obtain with annular ditch groove 3 by mold microdiecast
Biconvex non-spherical lens.
(2) have the one side of annular ditch groove as main reference plane biconvex non-spherical lens, carry out filming process and cut
Cut process；
Cutting processing path 4 in cutting action is rectangle, and the two-end-point of rectangular short side is respectively positioned in ringed line,
Two-end-point one of rectangular long side is located in ringed line, another is located at outside ringed line, and four of rear lens are completed in cutting
There will be annular ditch groove there are two the retention of the single side at angle on angle；
Cutting mode is diamond dust cutting.
(3) lens are cleaned, after the completion, arrow is completed by marking pen according to the label of annular ditch groove under the microscope
Leader knows 5, with display assembling datum level and assembly orientation.
This method has the advantage that
(1) by increasing the design of mold upper annular, can easily realize lens batch production facilitates label；
(2) camera lens that molding is completed simplifies rear road filming process and cuts due to having apparent single convex surface ring-shaped mark
Cut the judgement in lens clamping direction in process；
(3) the squarish dissymmetrical structure of well cutting can easily judge lens direction；(4) make under microscope
Clearly user can be instructed quickly to judge lens with the arrow mark that marking pen is completed
Coupling direction and assembling datum level.
Above-described is only some embodiments of the present invention.For those of ordinary skill in the art, not
Under the premise of being detached from the invention design, various modifications and improvements can be made, these belong to protection model of the invention
It encloses.
Claims (2)
1. the identification method of biconvex non-spherical lens directionality, it is characterised in that: the following steps are included:
