Description
[technical field]
The utility model relates to one kind during laser cutting machine automatic blanking, judge whether workpiece with clout has adhesion
Detection device and detection method.
[background technique]
Extensive with industrial automation is popularized, and demand of the people to production efficiency and factory are unmanned is increasing.
Especially laser cutting field, the harm due to laser to human eye, Unmanned operation are very necessary.Laser cutting machine it is unmanned
Production, first have to complete is exactly lathe automatic loading/unloading part.But for the automatic blanking of laser cutting, it is easy to deposit
In a problem: in laser cutting process, being frequently present of part workpiece can not be cut through, and lead to the feelings with clout there are adhesion
Condition.At this point, if carrying out feeding in a conventional manner, it is easy to drive entire clout (including on clout it is other cut through it is small
Plate) it is mobile.When this will result in blanking machine and continues to take other workpiece below, can not accurately grabbing workpiece, (workpiece is moved
It is dynamic), cause blanking to fail.
Therefore, it is necessary to provide the new blanking device with material strip adhesion detection function of one kind to solve the above problems.
[utility model content]
One of main purpose of the utility model is to provide a kind of blanking device with material strip adhesion detection function, lead to
The capacitance between the detection workpiece and needle bed that are crawled is crossed, achievees the purpose that detect whether workpiece with clout has adhesion, thus
It avoids continuing to grab still have adhesion workpiece with clout, causes other workpiece to be moved, influence blanking.
The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of blanking with material strip adhesion detection function
Device is used for the blanking operation of conductive material workpiece comprising clamping device that clamping workpiece moves up and down, for branch
Workpiece and the supporting mechanism with conducting function are supportted, is provided with the conductive part contacted with workpiece on the clamping device, it is described to lead
Pass through a capacitance sensing module electrical communication between electric portion and the supporting mechanism.
Further, the clamp structure is sucker or clamping jaw, is directly contacted with workpiece.
Further, the supporting mechanism is the needle bed of laser cutting machine.
It further, further include electrically connecting with the controller of capacitance sensing module electrical connection, with the controller
The alarm and the driving clamping device connect carries out the mobile driving assembly in space, the driving component and the controller
Electrical connection.
Further, the capacitance sensing module is capacitance sensor or capacitive detection circuit.
Compared with prior art, a kind of beneficial effect of the blanking device with material strip adhesion detection function of the utility model
Be: using capacitance sensor, capacitance between measuring workpiece and support product platform, realize detection workpiece whether with clout
There is the purpose of adhesion.Have the advantage that 1) detection is quick: the numerical value of capacitance sensor is real-time change, therefore can be with moment
Complete detection, fast response time；2) detection accuracy is high: capacitive sensor technology is mature, and in workpiece and clout adhesion or does not glue
Numerical value change is obvious when even, is not easy to cause misjudgment.
[Detailed description of the invention]
Fig. 1 is the structural schematic diagram of blanking device in the utility model embodiment；
Fig. 2 be the utility model embodiment in detection material whether the control flow chart of adhesion.
[specific embodiment]
Embodiment:
Fig. 1-Fig. 2 is please referred to, the present embodiment is a kind of blanking device 100, it is used for the blanking operation of conductive material workpiece,
It include clamping workpiece 101 move up and down clamping device 1, be used to support workpiece 101 and with conducting function support
Mechanism 2 is provided with the conductive part 3 contacted with workpiece on clamping device 1, passes through a capacitor sense between conductive part 3 and supporting mechanism 2
Survey 4 electrical communication of module.
Clamp structure 1 is sucker or clamping jaw, is directly contacted with workpiece.The present embodiment is particularly suitable for laser cutting device
In, in laser cutting machine, supporting mechanism 2 is the needle bed of laser cutting machine.
The blanking device 100 of the present embodiment further includes the controller 5 being electrically connected with capacitance sensing module 4 and controller 5
The alarm 6 and driving clamping device 1 of electrical connection carry out the mobile driving assembly (not identifying in figure) in space, driving assembly
It is electrically connected with controller 5.
Capacitance sensing module 4 is existing capacitance sensor or capacitive detection circuit.
The present embodiment additionally provides a kind of material strip adhesion rapid detection method based on above-mentioned blanking device comprising following
Step:
1) clamping device 1 is moved to feeding point grabbing workpiece；
2) workpiece is lifted up by clamping device 1, completely disengages 2 surface of supporting mechanism；
3) whether the capacitance that capacitance sensing module 4 detects between workpiece and supporting mechanism 2 is 0, if 0, is then issued viscous
Even alarm, if not 0, then workpiece and clout do not have adhesion, continue subsequent action；
4) judge whether the workpiece is the last one workpiece, if it is not, then clamping device 1 is moved to next feeding position
It sets, repeats step 2-3, until all workpiece are completed to grab.
Material strip adhesion rapid detection method of the present embodiment based on above-mentioned blanking device is clamped in workpiece and is lifted away from support machine
After 2 platform of structure, a capacitive sensing area is formed between 2 platform of workpiece and supporting mechanism, can sense a capacitance at this time.
If workpiece and clout do not have adhesion, capacitive sensing value is with apart from direct proportionality, i.e., distance between the two is bigger, then capacitor
It is worth bigger；When workpiece is contacted or is electrically connected with supporting mechanism 2, capacitance between the two is 0.Therefore, if it is clamped
There are if adhesion phenomenon between remaining workpiece on workpiece and supporting mechanism 2, then mechanism 1 is clamped in the workpiece and is lifted away from support
After mechanism 2, which forms access, at this point, by pressing from both sides by adhesion part and remaining workpiece and 2 electrically conducting of supporting mechanism
Whether holding the capacitance between workpiece and supporting mechanism 2 is 0, can be 0 by detecting the capacitance in above-mentioned capacitive sensing area therefore
Judge clamped workpiece with the presence or absence of adhesion, when avoiding blanking, causes the mistake of clout and other workpiece mobile, cause down
Material failure.
When in use, the material of the supporting mechanism platform of workpieces processing and support product must be conductor, otherwise can not feel
Answer capacitance；It when blanking, has to that product is first raised certain altitude, then starts capacitance detection, this highly can basis
Depending on practical board and workpiece situation, principle be guarantee workpiece can completely disengage needle bed while, avoid when workpiece with it is remaining
When material has adhesion, the obvious displacement of clout and other workpiece is caused after upper lift.
The present embodiment has the blanking device of material strip adhesion detection function, using capacitance sensor, measuring workpiece and support
Capacitance between product platform, realizes whether detection workpiece has the purpose of adhesion with clout.The sharpest edges of this programme have two
Point: 1) detection is quick: the numerical value of capacitance sensor is real-time change, therefore can complete to detect with moment, fast response time；2) it examines
It is high to survey precision: capacitive sensor technology is mature, and when workpiece is with clout adhesion or adhesion, numerical value change is obvious, does not easily cause
False judgment.
Above-described is only some embodiments of the utility model.For those of ordinary skill in the art,
Without departing from the concept of the present invention, various modifications and improvements can be made, these belong to practical
Novel protection scope.
