Description
[technical field]
The present invention relates to the coding detection technique, particularly a kind of detection method and structure thereof for detection of coding position skew on the die casting.
[background technology]
Coding is the process that adopts noncontact mode contents such as spray printing marking-up symbol, icon and bar code on product with ink jet numbering machine.In the production of metal crimp foundry goods, usually need carry out coding by the predeterminated position on a certain plane of die casting product, be beneficial in subsequent production die casting be identified.If actual coding position produces skew with predeterminated position on workpiece, then influence the follow-up identification operation of die casting.
See also Fig. 1, after the predeterminated position of the upper surface 11 of die casting 10 carries out coding 12, owing to lack object of reference as this coding 12 relative positions on this plane, therefore can't judge fast whether these coding 12 positions are offset.In the prior art, usually with measuring after the sampling of the die casting product on the coding production line, obtain actual coding position data, again with product design figure on coding predeterminated position data compare, could judge to draw the result whether the coding position is offset.
See also Fig. 2, the block scheme that it illustrates the detection method of prior art die casting coding position skew mainly may further comprise the steps:
Step 101: adjust the ink jet numbering machine position;
Step 102: die casting is positioned on the ink jet numbering machine spray printing direction;
Step 103: this die casting is carried out coding;
Step 104: the die casting that coding is finished is measured by the precision measurement instrument, obtained the measurement result of physical location;
Step 105: coding design attitude data on above-mentioned measurement result and the die casting are compared, judge whether the coding position is offset.
Because the detection method of prior art die casting coding position skew need be used precision measurement equipments such as projector, the detection cost is higher, this detection method can't detect in real time at production line in addition, testing process also requires the workman who possesses special operational technical ability just can fulfil assignment, labor intensive not only, and detection efficiency is lower.
[summary of the invention]
In view of this, the object of the present invention is to provide a kind of easy and simple to handle, efficient is higher can detect the detection method of coding position skew on the die casting in real time, overcoming the defective of prior art, thereby reduces production costs, enhance productivity.
In order to achieve the above object, the invention provides the detection method of coding position skew on a kind of die casting, it is characterized in that, mainly may further comprise the steps:
(1) in the default coding position of die casting die cast one coding contour structure, holds the coding content with cooperation;
(2) adjust the ink jet numbering machine position;
(3) die casting after the moulding is positioned on the ink jet numbering machine spray printing direction;
(4) die casting is carried out coding;
(5) whether the actual coding on the range estimation die casting exceeds the scope of holding of this coding contour structure.
By the auxiliary positioning effect of this coding contour structure, with this coding contour structure as object of reference, when the range estimation actual coding content exceed this coding contour structure hold scope the time, can draw testing result fast and be offset for the coding position; When the range estimation actual coding content do not exceed this coding contour structure hold scope the time, can draw testing result fast is that the coding position is offset.
In addition, the present invention also provides a kind of coding contour structure of the die casting for above-mentioned detection method, it is characterized in that, this coding contour structure is a bulge-structure or a recessed structure, this bulge-structure or recessed structure have the plane of holding, and it is suitable to hold the coding content that this holds the shape on plane and size and the profile of default coding content.
Preferably, this coding contour structure is a protruding mount structure, have the plane of holding in the encirclement of this projection mount structure, its shape and size and the profile of default coding content are suitable holding the coding content, coding content spray printing holding on the plane in this projection mount structure encirclement.When the coding position was offset, actual coding content exceeded this and holds holding scope and intersecting with the inside edge of this projection mount structure of plane.
Preferably, this coding contour structure is boss structure, and the upper surface of this boss structure is for holding the plane, and the profile of its shape and size and default coding content is suitable to hold the coding content, and coding content spray printing is on this boss structure upper surface.When the coding position was offset, actual coding content exceeded holding scope and intersecting with the edge of this boss structure of this upper surface.
Preferably, this coding contour structure is a recessed mount structure, have the plane of holding in the encirclement of this recessed mount structure, its shape and size and the profile of default coding content are suitable holding the coding content, coding content spray printing holding on the plane in this recessed mount structure encirclement.When the coding position was offset, actual coding content exceeded this and holds holding scope and intersecting with the inside edge of this recessed mount structure of plane.
Preferably, this coding contour structure is groove structure, and the bottom surface of this groove structure is for holding the plane, and the profile of its shape and size and default coding content is suitable to hold the coding content, and coding content spray printing is on this groove structure bottom surface.When the coding position was offset, actual coding content exceeded holding scope and intersecting with the edge of this groove structure of this bottom surface.
The detection method of coding position skew on the die casting of the present invention, by the object of reference of the one coding contour structure of moulding on die casting as the coding relative position, after actual coding, the testing result whether the coding position is offset only need be by the relative position relation of range estimation coding and this coding contour structure, i.e. whether coding exceeds the scope of holding of this coding contour structure is judged fast.Compared to prior art, the detection method of coding position skew need not other supplemental measurement tools on the die casting of the present invention, easy and simple to handle, detection efficiency is higher, and can detect in real time on line whether the coding position is offset on the die casting, overcome the defective of prior art, reduce production cost, improved production efficiency.
