Detailed description of the invention

Fig. 1 is the electrical connection diagram of self detection device of the spot welding fixture (SWFX) sensor of the utility model；

Fig. 2 is the installation diagram of self detection device of the spot welding fixture (SWFX) sensor of the utility model.

Specific embodiment

In order to make those skilled in the art be better understood when the technical solution of the utility model, below with reference to attached Its specific embodiment is described in detail in figure:

Please refer to Fig. 1 and Fig. 2, the most preferred embodiment of the utility model, a kind of self detection device of spot welding fixture (SWFX) sensor, Including spot welding robot 5, sensor group 2, sensor fault indicator lamp groups 3, sensor controller 1 and robot controller 4.

Spot welding robot 1 is connected with the output end of robot controller 4；Sensor group 2 includes six clamp sensors 21 ~26；Sensor fault indicator lamp groups 3 include a fixture malfunction indicator lamp 37 and six clamp sensor malfunction indicator lamp 31 ~36；Sensor controller 1 includes sensor signal input terminal 11, sensor detection signal output end 12 and welding signal output End 13；Six clamp sensors 21~26 are connected with the sensor signal input terminal 11 of sensor controller 1 respectively；One fixture Malfunction indicator lamp 37 and six clamp sensor malfunction indicator lamp 31~36 are detected with the sensor of sensor controller 1 respectively to be believed Number output end 12 is connected；The input terminal of robot controller 4 is connected with the welding signal output end 13 of sensor controller 1.

Sensor signal input terminal 11 includes six input ports 111~116, and sensor detection signal output end 12 includes Seven output ports 121~127；Six clamp sensors 21~26, six with sensor signal input terminal 11 correspondingly Input port 111~116 is connected；Six clamp sensor malfunction indicator lamp 31~36 and a fixture malfunction indicator lamp 37 are one by one Accordingly it is connected with seven output ports 121~127 of sensor detection signal output end 12.

Again referring to Fig. 2, sensor controller 1 uses Siemens 300PLC, six clamp sensors 21~26 be can be used Product detection sensor on original spot welding fixture (SWFX) 100, spot welding robot 5 is using the spot welding machine on original spot-welding equipment People, robot controller 4 use the control system of the spot welding robot on original spot-welding equipment.Sensor fault indicator lamp groups 3 are mounted on operation doorway 102, facilitate observation result；The manual reset button 101 of original spot welding system is also mounted at operation doorway 102, facilitate operation.

Self detection device of the spot welding fixture (SWFX) sensor of the utility model, the signal of six clamp sensors 21~26 acquisition Sensor controller is transferred to by six input ports 111~116 of the sensor signal input terminal 11 of sensor controller 1 It inside 1, is handled by 1 internal processes of sensor controller, after finding test problems, by the seven of sensor detection signal output end 12 Signal processing results are sent to sensor fault indicator lamp groups 3, sensor fault indicator lamp groups 3 by a output port 121~127 It should be mounted in operator is readily seen that and production process and be not easy the position encountered.Sensor fault indicator lamp groups 3 In six clamp sensor malfunction indicator lamp 31~36 be indicate corresponding six clamp sensors 21~26 it is normal whether, most The latter fixture malfunction indicator lamp 37 indicate be entire clamp sensor detection after result it is normal or problematic.Work as detection Rear jig malfunction indicator lamp 37 of finding the problem just is gone out, and cannot normally be reserved by reserve button at this time and be stopped producing.At this time Corresponding clamp sensor malfunction indicator lamp 31~36 will light, and prompt operator that should overhaul corresponding sensor.Therefore The case where barrier breaks down includes that sensor position loosens, normal open or normally closed, sensor cable disconnect after sensor body damage Or it is short-circuit, do not install correctly product, product more fill, fixture damage, fixture have foreign matter etc..Manual reset button 101 is installed On the left side on operation doorway, I can complete here with the original system reset pad of spot-welding equipment in maintenance of breaking down Afterwards, it presses and carries out self detection device to the spot welding fixture (SWFX) sensor of the utility model within manual reset button 101 3 seconds and answer Position.

Self detection device of the spot welding fixture (SWFX) sensor of the utility model, in conjunction with the sensing on the original fixture of spot-welding equipment Device is respectively processed its signal inside PLC, by comparative analysis, then removes the device reservation in control original system Function timely closes reservation function after sensor failure, and Robot Spot Welding system is made to stop production.Letter is exported simultaneously Number, which specific sensor of instruction occurs problem and needs repairing.Reset button is pressed after the completion of maintenance to eliminate alarm.

Self detection device of the spot welding fixture (SWFX) sensor of the utility model, principle are exactly to start pair after the completion of welding every time Clamp sensor is detected, from the opening of fixture until the closing of fixture, all sensors will be disconnected by primary To the process of connection, what we to be done is exactly to detect that the certain off and on of all the sensors is primary in this process, Clamp sensor must have the variation of signal in a cycle, the clamp sensor only changed can just be determined to be it is intact and Effective sensor at this moment will be defeated when some clamp sensor is just identified as failure occurred there is no signal intensity Indication signal out, while cutting off reserve channel.

In conclusion self detection device of the spot welding fixture (SWFX) sensor of the utility model, the automatic spot welding fixture (SWFX) that detects is uploaded The quality of sensor avoids the uncertainty of artificial point inspection.

Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate that this is practical new Type, and be not used as the restriction to the utility model, as long as in the spirit of the utility model, to the above Variation, the modification of embodiment will all be fallen in the Claims scope of the utility model.
