Description
Technical field
The present invention relates to blind hole technology field, and in particular to a kind of blind hole positioned at front glass cover plate adds
Work technique.
Background technology
Because there are screen, receiver, front camera and other equipment in mobile phone front, therefore in design fingerprint recognition module
During installation site, most manufacturer is using the rearmounted fingerprint recognition modular structure in the back side, and its is simple in construction, it is only necessary in hand
Perforate is covered after machine, then fixed placement fingerprint recognition module.
The fingerprint recognition blind hole processing technology of existing front glass cover plate, because the main material of glass is SiO2, this
The characteristic of material is hard and nonelastic, and the blind hole yield that it is processed is low.And preposition, narrow fingerprint recognition is even realized,
It may also can influence recognition effect.
The content of the invention
To solve above-mentioned problem, the present invention provides a kind of processing technology of blind hole positioned at front glass cover plate,
Its relatively big-diameter blind hole yield processed is high.
A kind of processing technology of blind hole positioned at front glass cover plate, its blind hole processing technology step include：
(1) sawing sheet：Obtain front glass cover plate material；
(2) CNC shapings：Using electroplating abrasion wheel rod, the fingerprint recognition position being pointed on front glass cover plate is carried out
Preliminary working, form blind hole；Its processing mode is to use to cut layer by layer, and plunge cut way is angle-inserting type；
(3) bis- refine blind holes of CNC：Using secondary localization tool, front glass cover plate is positioned, then, using plating sand
Rod is taken turns, blind hole is finished；
(4) clear off：Blind hole is cleared off；
(5) refine：Using electroplating abrasion wheel rod, blind hole is refined；
(6) cleaning, full inspection；
(7) strengthen：Blind hole is nitrogenized；
(8) clean, packaging and storage after inspection.
Further, secondary localization tool crown center position is provided with the mounting groove for placing front glass cover plate,
Mounting groove centre position is provided with through hole, and the through hole connects suction device by flexible pipe.
Further, several and the soft pipe connection are provided with the mounting groove and positioned at the bore periphery position
Air channel.
Beneficial effects of the present invention are：Its relatively big-diameter blind hole yield processed is high.
Brief description of the drawings
Fig. 1 is the front glass covering plate structure schematic diagram of mobile phone of the present invention.
Fig. 2 is the overlooking the structure diagram of the secondary localization tool of the present invention.
Fig. 3 is the cross section view in Fig. 2 centre positions.
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that specific embodiment described herein only to explain the present invention, not
For limiting the present invention.
As shown in figure 1, the front glass cover plate 1 of mobile phone is provided with the blind hole 11 for fingerprint recognition.
A kind of processing technology of blind hole 11 positioned at front glass cover plate 1 of the invention, its blind hole processing technology step include：
(1) sawing sheet：Obtain front glass cover plate material；
(2) CNC shapings：Using electroplating abrasion wheel rod, the fingerprint recognition position being pointed on front glass cover plate is carried out
Preliminary working, form blind hole；Its processing mode is to use to cut layer by layer, and plunge cut way is angle-inserting type；
(3) bis- refine blind holes of CNC：Using secondary localization tool, front glass cover plate is positioned, then, using plating sand
Rod is taken turns, blind hole is finished；
(4) clear off：Blind hole is cleared off；
(5) refine：Using electroplating abrasion wheel rod, blind hole is refined；
(6) cleaning, full inspection；Full inspection is carried out before nitridation, prevents from nitrogenizing defect ware, saves cost；
(7) strengthen：Blind hole is nitrogenized；
(8) clean, packaging and storage after inspection.
Processed using electroplating abrasion wheel rod, rather than common emery wheel, the main material for being due to front glass cover plate is
SiO2, processing difficulties.The appearance of electroplating abrasion wheel rod is electroplate with the material that hardness is far above SiO2.
As shown in Figures 2 and 3, the secondary crown center position of localization tool 2 is provided with for placing front glass cover plate
Mounting groove 21, mounting groove centre position are provided with through hole 211, and the through hole connects suction device by flexible pipe, and suction device is used for
Evacuate the air between front glass cover plate and mounting groove so that vacuum is formed in through hole, front glass cover plate is close to installation
Groove.
As shown in Figure 2 and Fig. 3, the mounting groove 21 is interior and is provided with several and institute positioned at the peripheral position of through hole 211
State the air channel 212 of soft pipe connection.
The principle of fingerprint recognition is：Screen portions (front glass cover plate) above fingerprint recognition chip are emptied,
Make its thinning, fingerprint recognition blind hole is formed, to realize penetrating for capacitance signal.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
Any modification, equivalent substitution or improvement made within refreshing and principle etc., should be included in the scope of the protection.
