Abstract
The utility model discloses an idle motion protection triggering device of a welding gun in a welding robot. The idle motion protection triggering device of the welding gun in the welding robot comprises a coil of a relay J connected between the output end and the ground end of a controller OUT5 in series, wherein the output end of the controller OUT5 outputs a high level when the welding gun carries out normal welding work and outputs a low level when the welding work is not carried out. A contactor A electrically connected with a welding gun head is connected with the scram signal input end EMG of the controller, the scram signal input end EMG of the controller is connected with a resistor R in series and then connected with a positive pole of a power source, and a contactor B electrically connected with a working table is connected with the normally-closed contactor J1 of the relay J in series and then connected with the ground end. The idle motion protection triggering device of the welding gun in the welding robot has the advantages that the triggering device is used in the welding robot, when the welding gun is in an idle motion process and the welding gun head runs into the working table, a scram protection circuit in the controller is triggered timely, so that the function of protecting the welding gun is achieved, and the failure that the welding gun is damaged is effectively prevented from happening.
Description
Technical field
The utility model relates to the control device of welding robot philtrum welding gun, refers more particularly to the protection flip flop equipment of welding gun.
Background technology
Along with the continuous development of society, enterprise is more and more higher to the requirement of production automation degree, and the application of welding robot also thereupon more and more widely.Under the control of the controller of welding robot, the welding gun of welding robot philtrum is when carrying out welding job, and the speed of service of welding gun is slower, is referred to as the microinching process usually; And when welding gun was in non-welding job state, the speed of its operation was very fast, and namely the speed during the welding gun idle stroke is very fast.For preventing that its welding gun rifle head is run into the workbench initiating failure in the welding gun idle stroke process, when need being provided, a kind of welding gun idle stroke can in time trigger the flip flop equipment that urgency in the controller of welding robot is stopped holding circuit.
The utility model content
The utility model technical issues that need to address are: the idle stroke protection flip flop equipment that welding gun among the welding robot people that urgency in a kind of controller that can in time trigger welding robot in the idle stroke process stops holding circuit is provided.
For addressing the above problem; the technical solution adopted in the utility model is: the idle stroke protection flip flop equipment of welding robot philtrum welding gun; comprise: the coil that is serially connected with the relay J between the controller OUT5 output and ground; controller OUT5 output is exported high level when welding gun carries out normal welding job; output low level when non-welding job; the contact A that is electrically connected with welding gun rifle head is connected with the emergent stop signal input EMG of controller; be connected with power positive end behind the emergent stop signal input EMG series resistor R of controller, be connected with earth terminal with the normally-closed contact J1 serial connection back of relay J with the contact B that workbench is electrically connected.
Further, the idle stroke of aforesaid welding robot philtrum welding gun protection flip flop equipment, wherein, the normally opened contact of relay J is serially connected with in the switching circuit of welding robot philtrum welding wire machine.
Further, the idle stroke of aforesaid welding robot philtrum welding gun protection flip flop equipment, wherein, contact A is electrically connected with the spring that is installed in welding gun rifle head lower end.
The beneficial effects of the utility model: in the welding robot people, use above-mentioned flip flop equipment; when welding gun is in the idle stroke process and welding gun rifle head when running into workbench; the urgency that can in time trigger in the controller is stopped holding circuit; thereby play the effect of protection welding gun, effectively avoided the impaired fault of welding gun to take place.
Description of drawings
Fig. 1 is the circuit theory schematic diagram of the idle stroke protection flip flop equipment of welding robot philtrum welding gun described in the utility model.
Fig. 2 is the spring mounting structure schematic diagram of welding gun rifle head described in the utility model lower end.
The specific embodiment
Be described in further details below in conjunction with accompanying drawing and the utility model of optimum embodiment.
As Fig. 1; shown in Figure 2; the idle stroke protection flip flop equipment of welding robot philtrum welding gun; comprise: the coil that is serially connected with the relay J between the controller OUT5 output and ground; controller OUT5 output is exported high level when welding gun carries out normal welding job; output low level when non-welding job; the contact A that is electrically connected with welding gun rifle head 1 is connected with the emergent stop signal input EMG of controller; be connected with power positive end after the resistance R that the emergent stop signal input EMG serial connection of controller is ten kilohms; be connected with earth terminal with the normally-closed contact J1 serial connection back of relay J with the contact B that workbench is electrically connected; in the present embodiment; the normally opened contact J2 of relay J is serially connected with in the switching circuit of welding robot philtrum welding wire machine; in addition, contact A is electrically connected with the spring 2 that is installed in welding gun rifle head 1 lower end in the present embodiment.
Operation principle of the present utility model is as follows: when controller control welding gun carries out welding job, the OUT5 output output high level of controller, make the relay adhesive, this moment, J1 disconnected, the J2 conducting is in this process, even contact and conducting with the workbench collision owing to reasons such as welding slag cause welding gun rifle head 1, can not trigger the anxious power failure road in the controller yet, thereby avoid taking place solder failure.When welding gun is finished welding job and is in the idle stroke process, controller OUT5 output output low level (closing), relay J dead electricity and restoring to the original state, the J1 conducting, J2 disconnects, when the spring 2 of welding gun rifle head 1 lower end is run into workbench, contact A and contact B conducting, the emergent stop signal input EMG of controller obtains the low level triggering signal, thereby the anxious power failure road in the startup controller, welding gun is effectively protected in the idle stroke of rapid movement, avoid taking place because of the impaired fault of welding gun collision workbench, because welding gun rifle head 1 lower end is equipped with spring 2, on the one hand, spring 2 plays the effect of buffering, can effectively slow down the collision between welding gun rifle head 1 and the workbench; On the other hand, spring 2 touches behind the workbench with regard to the trigger protection circuit, can more effectively protect welding gun rifle head 1 like this, avoids welding gun rifle head 1 and workbench direct collision.
