Description

Detection method for coiled material without uncoiling
Technical Field
The invention belongs to the technical field of coiled strip detection, and particularly relates to a detection method for coiled strip without uncoiling.
Background
As is known, many electronic products need to be rolled and packaged by using a coiled material, but no bad products are ensured to flow into the market, and a detection procedure is needed after the coiled material is rolled.
At present, the detection mode for the coiled belt coil stock is as follows: and the other side of the coil is reeled, and corresponding detection equipment is arranged on the uncoiling path of the coil material, so that the detection of the products is implemented in a screening mode one by one to judge whether unqualified products exist in the whole coil of belt material.
Obviously, the above detection method has the following disadvantages:
1. detection is necessarily carried out in the unwinding process, the required detection time is long, the efficiency is low, and particularly, the detection cost is higher for electronic products with higher qualified rate;
2. once the product is detected to have a problem, the detection cannot be continued, and the machine can only be stopped for waiting for manual treatment.

In order to overcome the defects of the prior art, the invention aims to provide a brand-new detection method for a disc strip without unwinding.
The technical scheme of the invention is as follows: a detection method for a coiled material without uncoiling comprises the following steps:
s1, acquiring detection points and product sequence numbers
The method comprises the following steps of (1) horizontally placing the disc belt material and taking a picture comprehensively to obtain detection points distributed in the disc belt material, forming Archimedes spiral route track points according to the distribution of each detection point, and sequentially numbering from outside to inside or from inside to outside along the track points;
s2, partition screening
1) Dividing N sorting areas according to the number of products in the plate belt material and the diameter of the reel, wherein N is not less than 2 and is an integer;
2) carrying out image acquisition and amplification processing on each inspection region, and covering a part of the side edge of each inspection region adjacent to the inspection region to form subarea overlapping;
3) deleting the detection points with repeated serial numbers in the adjacent overlapping parts of every two adjacent sorting areas, detecting all other detection points in the obtained sorting areas, and simultaneously finishing all the detection of the detection points in all the sorting areas;
s3, determination of detection result
If no detection point is unqualified, the whole coil of the disc is qualified; if one detection point is unqualified, at the moment, the disc belt material is uncoiled and is uncoiled to the number corresponding to the detection point, and then the product is manually replaced or removed.
Preferably, the N sorting areas are equally divided. Therefore, the detection information of each detection point can be relatively obtained, so that the detection omission is avoided.
According to a particular embodiment and preferred aspect of the invention, the distribution is in an annular array centered on the centre of the disc band. This can facilitate the division and formation of the sorting zones.
Preferably, each sorting area comprises an arc-shaped section with a central angle of 360 DEG/N and subarea overlapping parts positioned on two opposite sides of the arc-shaped section, wherein the subarea overlapping parts are positioned on the arc-shaped section corresponding to the central angle of 1 DEG-5 deg. Thus, through the arrangement of the partition overlapping part, the omission of detection points or repeated detection caused by partition is avoided.
In this example, the divisional overlapping portions are located at arc segments corresponding to central angles of 2 ° -3 °, and the repetition numbers are deleted from the sequence numbers in S1. The missing detection rate is zero at the moment, and the quick detection efficiency is not influenced.

Set up like this, directly after the unwinding, through the stack of digit, can seek the product of finding appointed serial number fast and accurately, and then make things convenient for the manual work to carry out the product and change or remove the processing.
Preferably, when numbering is carried out along the track points from inside to outside in sequence, the serial number 1 corresponds to a product with the nearest inner end of the coil material, the serial number m corresponds to a product with the nearest outer end of the coil material, and if the detection points are unqualified, the products are unfolded according to the sequence of m, m-1.. 3, 2 and 1 so as to complete product replacement or removal processing. Set up like this, directly after the unwinding, through the back-off of digit, can seek the product of finding appointed serial number fast and accurately, and then make things convenient for the manual work to carry out the product and change or remove the processing.
In S2, the product corresponding to each detection point is scanned by using the laser. Therefore, once the product has surface or internal defects, parts are not assembled and the like, the detection conclusion can be rapidly and accurately drawn.
Preferably, in S3, the web is unwound once the detection result obtained from the detection point is not qualified, and the unwinding mechanism includes an unwinding component, a winding component, and a scanning and reading component, wherein the unwinding of the web is controlled by the scanning and reading component. In this way, after the roll is unwound to the position of the designated serial number, the roll unwinding is suspended, so that the product replacement or removal processing is conveniently carried out manually.
Further, scanning reading part includes counter and recognizer, and wherein the product on the recognizer uses discernment dribbling, and the counter can count down or count in the same direction as the number, and so, the operator of being convenient for that the track point that forms is no matter from inside to outside or outside to inside, and the homoenergetic is accurate finds the product that the sequence number corresponds to make things convenient for the manual work to carry out the product and change or remove the processing.
