Description
Technical field
The present invention relates to laser marking field, the method for specifically a kind of three laser on-line markings of bottle cap.
Background technique
Currently, in bottle cap production industry, more and more bottle cap surfaces or internal using laser marking bar code, two dimension
The contents such as code, pattern, text, number, letter.During mark, generally use at present a set of bottle cap ancillary equipment (riko cover and
Vacuum conveying belt) it is much big with a set of or two sets of laser marking devices progress on-line markings, the host speed of bottle cap production at present
In the production capacity of single head or double end on-line marking, numerous bottle cap manufacturing enterprises are in order to match host production capacity, it has to increase equipment, make
At place, cost, energy consumption, personnel's waste.Modern bottle cap manufacturing enterprise production cost is lower and lower, artificial demand is fewer and fewer,
Increasingly higher demands also proposed to mark efficiency, the mark speed promotion of laser marking machine is inexorable trend.
Currently, laser on-line marking field, mostly uses 1 laser marking machine (single head laser) or 2 laser marking machines (double
Head laser) a set of vacuum conveying belt progress mark of cooperation.Not increasing bottle cap ancillary equipment separately in user, (riko cover and vacuum are defeated
Send) but in the case where needing to accelerate the conveying speed of bottle cap to improve production efficiency, since by 1 laser marking machine, (single head swashs
Light) or 2 laser marking machine (dual-headed laser) mark speed limitation, the on-line marking efficiency of bottle cap can not be improved to meet need
It asks.
Summary of the invention
It is an object of the present invention to provide a kind of methods of three laser on-line markings of bottle cap, make the effect of the online laser marking of bottle cap
Rate is remarkably enhanced, and laser marking machine can also play more powerful advantage in the online laser marking application field of bottle cap.
The technical scheme to solve the above technical problems is that
A kind of method of three laser on-line markings of bottle cap, includes the following steps:
1) bottle cap is sent to preset laser marking region, the laser head below laser head on the conveyor line and is set as three
It is a；
2) laser marking overlying regions are provided with pattern recognition device, described image identification device is to entering laser marking
The bottle cap in region carries out image recognition, and speed, each bottle cap according to three one group of bottle cap, by controller to every group of bottle cap
Between interval calculated；
3) the laser head underface region position of regional location and pattern recognition device identification immediately below each laser head is established
The mapping relations set；
4) position of each bottle cap of pattern recognition device identification is substituted into the mapping relations in step 3), upon a match,
Illustrate that the bottle cap is in immediately below laser head, the laser machine of controller triggering at this time carries out mark；
The beneficial effects of the present invention are: bottle cap is sent to preset laser marking range below laser head by vacuum conveying belt
When region, a laser head is triggered at interval of two bottle caps and carries out mark, three laser heads alternately carry out mark to bottle cap.Three
Laser head can carry out mark to corresponding three bottle caps vertical in vacuum respectively simultaneously.A mark is carried out every two bottle caps.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention；
Specific embodiment
The principle and features of the present invention will be described below with reference to the accompanying drawings, and the given examples are served only to explain the present invention, and
It is non-to be used to limit the scope of the invention.
As shown in Figure 1, a kind of method of three laser on-line markings of bottle cap, includes the following steps:
1) bottle cap is sent to preset laser marking region, the laser head below laser head on the conveyor line and is set as three
It is a；
2) laser marking overlying regions are provided with pattern recognition device, described image identification device is to entering laser marking
The bottle cap in region carries out image recognition, and speed, each bottle cap according to three one group of bottle cap, by controller to every group of bottle cap
Between interval calculated；
3) the laser head underface region position of regional location and pattern recognition device identification immediately below each laser head is established
The mapping relations set；
4) position of each bottle cap of pattern recognition device identification is substituted into the mapping relations in step 3), upon a match,
Illustrate that the bottle cap is in immediately below laser head, the laser machine of controller triggering at this time carries out mark；
One, mark principle
When bottle cap is sent to preset laser marking range areas below laser head by vacuum conveying belt, at interval of two bottles
Lid triggers a laser head and carries out mark, and three laser heads alternately carry out mark to bottle cap.Three laser heads can be right respectively simultaneously
Vertical corresponding three bottle caps carry out mark in vacuum.A mark is carried out every two bottle caps.
Two, mark improved efficiency principle analysis
Single head laser marking efficiency calculation formula
The adjacent bottle cap interval mark efficiency (a/minute)=bottle cap speed (m/min) ÷ (rice /) × laser head number
Such as:
Single head laser marking machine calculates mark efficiency by parameters described below
Bottle cap speed are as follows: 4 ms/min
Adjacent bottle cap interval are as follows: 0.01 meter/
Laser head number: 1
Mark efficiency=4 (m/min) ÷ 0.01 (rice /) × 1=400/minute
Dual-head laser marking efficiency calculation formula
Mark efficiency (a/minute)=bottle cap speed (m/min) ÷ is separated by bottle cap interval (rice /) × laser head number
Such as: double-ended laser marking machine calculates mark efficiency by parameters described below
Bottle cap speed is promoted are as follows: 6 ms/min
It is separated by bottle cap interval are as follows: 0.02 meter/
Laser head number: 2
Mark efficiency=8 (m/min) ÷ 0.02 (rice /) × 2=800/minute
Three laser marking efficiency calculation formula
Mark efficiency (a/minute)=bottle cap speed (m/min) ÷ is every two bottle cap intervals (rice /) × laser head
Number
Such as: three laser marking machines calculate mark efficiency by parameters described below
Bottle cap speed is promoted are as follows: 12 ms/min
Every two bottle cap intervals are as follows: 0.03 meter/
Laser head number: 3
Mark efficiency=12 (m/min) ÷ 0.03 (rice /) × 3=1200/minute
Concrete operating principle: during laser on-line marking:
When the interval of the amasthenic lens range > vacuum conveying belt upper bottle cover of single head laser marking machine, laser marking machine is certainly
Body efficiency still has She's amount, can promote line speed, increases bottle cap interval and is allowed to consistent with mark range, plays marking machine most
Big efficiency.
When the amasthenic lens of single head laser marking machine range=vacuum conveying belt upper bottle cover interval, laser marking machine is certainly
Body efficiency has reached highest, can not promote conveying tape speed and increase bottle cap interval, mark efficiency can not be promoted.
When vacuum conveying belt requires speed to be promoted to 3 times, conveying production capacity is also promoted to 3 times, then bottle on vacuum handling band
The interval of lid needs to keep preceding consistent with speed-raising.In this case, three laser of configuration on same vacuum handling band can be taken,
The amasthenic lens of laser marking machine is changed to original 3 times of mark ranges simultaneously.Such 1 laser head can be at 3 times of bottle cap intervals
In the range of complete a bottle cap mark (i.e. laser head completes a mark, and centre needs two bottle caps in interval), and by
Every other two bottle cap then by other 2 laser heads complete laser marking.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
