Description
Technical field
The invention belongs to detonator automatic identification technology field more particularly to a kind of detonator for detonator automatic identification machine are fixed
Bit scan device.
Background technique
The use of public security department's regulation detonator must be registered clearly, shown custodian, provided people, receive people, use
Project, place to use, quantity, type, waste product etc., all items are indispensable, there is stringent land use reform.
Currently, the unit using detonator uses detonator in management substantially according to the requirement of public security department, detonator is being provided
Formality on it is also roughly the same, i.e., " manually copy code, registration, counting, signature, granting, archive ".The small unit of detonator dosage uses
It is artificial to provide, it can satisfy the needs of production substantially, still, the biggish unit of detonator usage amount, if big in the short time
Batch provides detonator, needs to spend many manpowers and longer time, this seriously inhibits production efficiencys, do not adapt to height
The needs of the modern production of speed development.In addition, manually providing the defect of detonator also: (1) cannot efficiently and accurately complete to give birth to
Detonator provides all registrations and receives formality in production；(2) it is many that there are human factors, be easy to cause granting mistake.
As national correlation department is to the dangerous material process of circulation strict control such as detonator, it is desirable that the detonator pipe in actual production
Reason increasingly refines in place, detonator production and use will be included in computer and be managed automatically seems to be close at hand, so detonator volume
The quickly and efficiently identification of code is applied to manage also more more and more urgent.
And in detonator coding automatic identification technology, the positioning scanning technique for solving detonator is first had to, detonator is being scanned
Detonator position in cataloged procedure is fixed, and ensure that safety of the detonator in identification encoding operation.
Summary of the invention
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide a kind of safely and effectively detonator positioning scanning dress
It sets.
In order to achieve the above objectives, the present invention is implemented with the following technical solutions: detonator positions scanning means, comprising:

Expect that part, non-transparent material part are metal or plastic construction, this structure reduces the possibility of quartz glass bring explosion
Property, also reduce overall cost；The circular scanning instrument of use comprehensive can be scanned detonator coding, and structure is simple,
It is easy to operate.
Further, there is hole in the closed end of the non-transparent material part.
Further, the detonator positioning mechanism further includes position sensor, and the position sensor is optical sensor,
The position sensor is mounted on the closed end of the non-transparent material part by the hole.
When detonator is inserted into the pre-position of the pipe sleeve, the optical sensor can perceive the position of detonator, thus
It warns, so that operator can understand detonator the pipe sleeve position the case where in real time.
Optionally, the outer diameter of the internal diameter of the pipe sleeve and the detonator is adapted.
The pipe sleeve can do limited distance along the axis of first pedestal and second pedestal and move, when insertion thunder
Guan Shi, simultaneously further inwardly movement after detonator is contacted with pipe sleeve, then detonator drives pipe sleeve inwardly to move, when arrival predetermined position
When, the pipe sleeve and detonator keep stablizing and trigger the position sensor, when extracting detonator, the pipe sleeve homing
It sets.
Further, the non-transparent material part is metal structure or plastic construction.
Further, the non-transparent material part and the transparent part are separately mounted to first pedestal and described
On second pedestal.
Further, the detonator positioning mechanism further includes explosion-proof sealing ring, and the explosion-proof sealing ring is arranged described
Between transparent part and second pedestal.
Further, the endpoint of one end with lead of the length of the transparent part and detonator rises to detonator coding
The distance of beginning position matches.
The length of the transparent part mainly cooperates scanner to be scanned and be arranged to detonator coding, can be big
In be equal to detonator one end with lead endpoint to detonator coding start bit distance.
Further, the transparent part is quartz glass structure.
Further, the detonator positioning scanning means further includes support frame, and support frame as described above is fixedly mounted on described
Pipe sleeve side, the scanner are mounted on support frame as described above.
The additional aspect of the present invention and advantage will be set forth in part in the description, and will partially become from the following description
Obviously, or practice through the invention is recognized.
