Description
Technical field
The present invention relates to automobile industry automatic welding control field, which provides equipment mistake proofing detection function necessary
There is the requirement such as high stability and convenient later maintenance, the present invention is a kind of raising fixture mistake proofing detection function stability
Method, specifically a kind of method for realizing fixture mistake proofing detection function stability.
Background technique
In automobile manufacturing industries field, most of fixture arc welding equipment all has mistake proofing detection function to the workpiece of production
Can, traditional design mode generally realizes mistake proofing detection function by installing additional close to inductive switching device, the disadvantage is that detection error is big,
Inductor touches easy to damage after heat source, generates the phenomenon of signal line short circuit, causes in equipment DC24 power supply power supply when serious
Disconnected, equipment paralysis is safeguarded after equipment time-consuming and laborious, influences to produce production capacity.
Summary of the invention
The present invention is to solve above-mentioned technical problem and the technical solution adopted is that provide a kind of realization fixture mistake proofing detection function
The method of stabilizability uses signal isolating device to can effectively avoid detection jitter and short circuit phenomenon after using new departure instead
Generation, reduce field maintenance person's maintenance workload, improve production efficiency.
In order to realize the above technical effect, the technical solution adopted by the present invention is that:
Using mechanical sension unit by way of contact inductive signal whether there is or not；
Mechanical sension unit connects isolation signals processing unit by wiring, and input is believed by isolation signals processing unit
PLC is sent to after number isolation processing.
The method of above-mentioned realization fixture mistake proofing detection function stability, in which:
The machinery sension unit includes shield one, and shield two, the shield one are arranged on the shield one
Including base portion and column portion, the shield is second is that right angle vertical plate, the upper surface of described column portion are arranged connecting pin and pacify
Hole location is filled, connecting pin is installed in connecting pin installation hole location, insulating bushing one, the connecting pin are set around the connecting pin
Lower section be arranged cross-over block one；In addition, also setting up gasket, cross-over block two on column portion, on cross-over block two also
Insulating bushing two is set, detection contact is set on connecting pin.
The method of above-mentioned realization fixture mistake proofing detection function stability, in which: the isolation signals processing unit includes
Signal input part and signal output end, are isolated between signal input part and signal input part.
The present invention has the following beneficial effects with respect to the prior art: 1) structure of sension unit can pass to avoid heat source
It leads, electronic component is avoided to damage；2) spring arrangement is installed, detection contact can be between the detection contact and pedestal of sension unit
It is close to workpiece sensing position, avoids input signal from cutting in and out and happen, be conducive to equipment stable operation.
Detailed description of the invention
Fig. 1 is the system diagram applied in implementation method.
Fig. 2 is the structural schematic diagram of mechanical sension unit.
In figure:
1 shield, one 2 cross-over block, one 3 insulating bushing, one 4 shield, 25 connecting pin, 6 gasket, 7 insulating bushing two
8 cross-over blocks two
Specific embodiment
Traditional approach: sensor directly contacts workpiece, and workpiece can be being easy hair in heat transfer to sensor when welding
Blanching is bad, and equipment DC24V control power supply short circuit causes whole system to paralyse when serious.Sensor side orientation is easy to appear when installing
Induction less than to the case where occur, detect jitter.
The present invention provides a kind of methods for realizing fixture mistake proofing detection function stability, in which:
Using mechanical sension unit by way of contact inductive signal whether there is or not；
Mechanical sension unit connects isolation signals processing unit by wiring, and input is believed by isolation signals processing unit
PLC is sent to after number isolation processing.
The machinery sension unit includes shield 1, and shield 24, the shield are arranged on the shield 1
One 1 include base portion and column portion, and the shield 24 is right angle vertical plate, the setting connection of the upper surface of described column portion
Pin installation hole location installs connecting pin 5 in connecting pin installation hole location, insulating bushing 1, institute is arranged around the connecting pin 5
State the lower section setting cross-over block 1 of connecting pin 5；In addition, gasket 6, cross-over block 28 are also set up on column portion, exhausted
Insulating bushing 27 is also set up on edge cushion block 28, and detection contact is set on connecting pin 5.The isolation signals processing unit includes letter
Number input terminal and signal output end, are isolated between signal input part and signal input part.
Although the present invention is disclosed as above with preferred embodiment, however, it is not to limit the invention, any this field skill
Art personnel, without departing from the spirit and scope of the present invention, when can make a little modification and perfect therefore of the invention protection model
It encloses to work as and subject to the definition of the claims.
