Surely will be after the completion of all weld seams all weld, workpiece could be taken out and detected by worker, thus waste many welderings
Time and solder wire material are connect, cost is improved.
Invention content
The present invention in order to overcome the deficiencies of the prior art, provides a kind of detection device for fusion length, can in welding
It can carry out judging whether weld seam is qualified after completing a weld seam with every welding, if unqualified can take out at once, carry out down
The welding of one workpiece, improves the detection efficiency of weld seam in this way, and avoids and waste a large amount of welding wire, and reduction is welded into
This.
To achieve the above object, a kind of detection device for fusion length, including wire feed bucket, wire-feed motor are designed, it is special
Sign is：It is directly provided with wire feed measuring mechanism in wire feed bucket and wire-feed motor, and wire feed measuring mechanism is mounted on the pillar of fence
On；The wire feed measuring mechanism includes PLC, counting module.
The PLC is SIEMENS PLC.
The counting module model FM350-1.
The counting module is mounted on by cable connection encoder, encoder on welding robot.
The PLC program is as follows：
（1）Fixture starts clamping workpiece；
（2）Workpiece is transferred to welding position by fixture, and robot starts to work；
（3）Robot runs to specified welding position, and sends a signal to welding machine and start to weld；
（4）Welding machine carries out the welding starting the arc；
（5）Minor arc is successfully established；
（6）Judge whether the time that the starting the arc is kept is greater than the set value, is the length of then encoder operation detection welding wire；Otherwise
Workpiece is unqualified, and unqualified workpiece input is scrapped after case and resetted；
（7）The length of encoder operation detection welding wire judges the use length of welding wire whether in setting value, is then weld seam
It is qualified；Otherwise weld seam is unqualified, and unqualified workpiece input is scrapped after case and resetted；
（8）After weld is accepted, continue welding job, until all weld seams are completed and after qualification, it is qualified to complete workpiece
Summarize；
（9）Unqualified workpiece input is scrapped after case and is resetted, and clamping workpiece is then re-started.
The present invention compared with the existing technology, provides a kind of detection device for fusion length, can be with every weldering in welding
Connecing can carry out judging whether weld seam is qualified after completing a weld seam, if unqualified can take out at once, carry out next work
The welding of part, improves the detection efficiency of weld seam in this way, and avoids and waste a large amount of welding wire, reduces welding cost.
Description of the drawings
Fig. 1 is flow chart of the present invention.
Specific implementation mode
The invention will now be described in further detail with reference to the accompanying drawings.
It is directly provided with wire feed measuring mechanism in wire feed bucket and wire-feed motor, and wire feed measuring mechanism is mounted on the pillar of fence
On；The wire feed measuring mechanism includes PLC, counting module.
PLC is SIEMENS PLC.
Counting module model FM350-1.
Counting module is mounted on by cable connection encoder, encoder on welding robot.
As shown in Figure 1, PLC program is as follows：
（1）Fixture starts clamping workpiece；
（2）Workpiece is transferred to welding position by fixture, and robot starts to work；
（3）Robot runs to specified welding position, and sends a signal to welding machine and start to weld；
（4）Welding machine carries out the welding starting the arc；
（5）Minor arc is successfully established；
（6）Judge whether the time that the starting the arc is kept is greater than the set value, is the length of then encoder operation detection welding wire；Otherwise
Workpiece is unqualified, and unqualified workpiece input is scrapped after case and resetted；
（7）The length of encoder operation detection welding wire judges the use length of welding wire whether in setting value, is then weld seam
It is qualified；Otherwise weld seam is unqualified, and unqualified workpiece input is scrapped after case and resetted；
（8）After weld is accepted, continue welding job, until all weld seams are completed and after qualification, it is qualified to complete workpiece
Summarize；
（9）Unqualified workpiece input is scrapped after case and is resetted, and clamping workpiece is then re-started.
Weld seam state mainly comprises the following steps：
1. weld data collecting part：Every weld seam has corresponding weld interval and length, there is setting value and reality respectively
Point of actual value, setting value, which is artificial setting, has operator's permission；Actual value be in welding process the practical time consumed and
Length, deviation are also manually to set（For length）.
2. weld seam judges result display portion：The judgement result of every weld seam all can here it is shown that, weld completion every time
Afterwards, when fixture rotates supreme material position, the weld seam result of the fixture will be shown herein.Meanwhile corresponding fixture number also can
It is shown（No. 1 fixture or No. 2 fixtures）.
3. manual wire-feeding part：There are one manual wire feed buttons on picture, when operation mode is in manual mode, manually
By lower button, PLC will be instructed to the wire feed of one 3s of robot, and robot will send out the welding wire of 3s, manual wire feed length
What is shown is exactly the length of robot hand wire vent.This function mainly for detection of encoder gathered data error size.
4. alarm indication：If encoder is in slipping state, the skidding alarm of corresponding encoded device can be aobvious in picture
Show.Equally, according to the working quantity of setting, if reaching the value that robot needs clear rifle manually, it just will appear phase on that picture
In requisition for the prompt of manual clear rifle.
Weld is accepted basis for estimation：
1. the starting the arc success time：Calculate the first time starting the arc successful duration, when practical between be more than setting time when,
Judge that weld seam welding is qualified.When being less than or equal to setting time between when practical, judge that weld seam welding is unqualified, and set one
Such as " No. 1 weld seam current interruption ", " No. 2 weld seam current interruptions ", " No. 3 weld seam current interruptions ", " No. 4 weld seam current interruptions " of a current interruption signal, while in HMI
Display.
2. welding wire consumes length：Welding wire consumption calculating after first time starting the arc success, when welding wire consumes length
When in the weld seam allowable range, judge that weld seam welding is qualified.When welding wire consumes length not in the weld seam bound section,
Judge that unqualified and one unqualified signal of length of set of weld seam welding such as " No. 1 fusion length is unqualified ", " No. 2 weld seams are long
Spend unqualified ", " No. 3 fusion lengths are unqualified ", " No. 4 fusion lengths are unqualified ", while being shown in HMI.
When starting the arc success time, welding wire consumption length either condition are unqualified, which is judged to unqualified, while the workpiece
It is judged to unqualified.
By this set welding wire length detection device can effectively control every weld seam whether normal weld and every weld seam
Whether welding wire usage amount is normal, to effectively ensureing that the welding quality of our products plays the role of prodigious detection.
