Abstract
The invention provides a method for replacing a contact tube outside an arc welding station of a robot and a replacing system realizing the method. The arc welding station is arranged inside a safety fence. The method for replacing the contact tube comprises the following steps: when the gun cleaning of the contact tube reaches specified times, the robot automatically stops welding; a robot body sends the contact tube out from the station so as to replace the contact tube. When the method is adopted for replacing the contact tube on an arc welding gun, the robot body automatically sends the welding gun out from the station so that operating personnel can replace the contact tube of the welding gun outside the station and do not need to enter the safety fence for replacing the contact tube, so that the personnel safety of the operating personnel is guaranteed better, the time of replacing the contact tube by the operating personnel is also shortened, and the working efficiency is accelerated. Moreover, after the contact tube is replaced, the location degree deviation of the contact tube is detected through a track verification module, so that the batch weld line offset caused by deviation of sending welding wires of the contact tube is avoided, and the welding quality is guaranteed.

Detailed description of the invention
By particular specific embodiment explanation embodiments of the present invention, person skilled in the art scholar can understand other advantages of the present invention and effect easily by the disclosed content of this description below.
Refer to Fig. 1 to Fig. 2.Notice, appended graphic the illustrated structure of this description, ratio, size etc., all contents in order to coordinate description to disclose only, understand and read for person skilled in the art scholar, not in order to limit the enforceable qualifications of the present invention, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, not affecting under effect that the present invention can produce and the object that can reach, all should still drop on disclosed technology contents and obtain in the scope that can contain.Simultaneously, in this description, quote as " on ", the term of D score, " left side ", " right side ", " centre " and " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the present invention, the change of its relativeness or adjustment, changing under technology contents, when being also considered as the enforceable category of the present invention without essence.
Fig. 2 shows a kind of embodiment of the outer ignition tip replacing of robot of the present invention arc-welding station method and system, and the outer ignition tip replacing system of robot arc-welding station comprises PLC controller 1, robot control cabinet 2, robot body 3, arc welding 4, welding gun 5.Arc-welding station is arranged in safe fence, PLC controller 1 carries out two-way communication with robot control cabinet 2 and is connected, robot control cabinet 2 control bodies 3 move, welding gun 5 is positioned on robot body 3, robot body 3 drives welding gun 5 to move, arc welding 4 is connected control welding gun 5 and welds with welding gun 5, on PLC controller 1, be also connected with control button 6, signal alarm set 7 and track correction verification module 9, track correction verification module 9 communicates to connect by robot control cabinet 2 and PLC controller 1, controls welding gun and on track verifying plate, carries out checking routine.PLC controller 1 is also connected with a touch-screen 8, can realize human-computer dialogue by touch-screen 8.
Replacing method below in conjunction with the outer ignition tip of robot arc-welding station is further described:
The outer ignition tip of above-mentioned robot arc-welding station is changed system in the time of work, first detect the number of times of the clear rifle of ignition tip on welding gun 5 by PLC controller 1, rifle number of times as clear in ignition tip reaches regulation requirement, PLC controller 1 by robot control cabinet 2 control welding gun stop welding, control signal alarm set 7 sends sound and light alarm signal, reminds operating personnel to change the ignition tip on welding gun 5.Now operating personnel press control button 6 for the first time, and PLC controller 1 opens welding gun 5 by robot control cabinet 2 and station sent by welding gun 5 by control body 3, changes the ignition tip on welding gun 5 by operating personnel; After ignition tip has been changed, operating personnel press control button 6 for the second time, robot body 3 is sent welding gun 5 back to station and on track verifying plate, is first carried out track checking routine, has verified that rear PLC controller 1 makes signal alarm set 7 send the sound and light alarm signal of alert inspection calibration.As verification is passed through, operating personnel make its stop alarm, and welding gun 5 continues to enter duty.If verification is not reported to the police by signal alarm set 7 is lasting, calling operating personnel reaffirm.
The outer ignition tip of above-mentioned robot arc-welding station is changed system in the time that the ignition tip of welding gun reaches the clear rifle number of times of regulation, welding gun will stop welding automatically, while robot body is automatically sent station by welding gun and is carried out ignition tip replacing, adopting the ignition tip that operating personnel get final product Butt welding gun in safe fence outside in this way changes, and in safe fence, carry out ignition tip replacing without entering into again, shorten like this time that operating personnel change ignition tip, accelerate operating efficiency, after adopting according to statistics the method, each time of changing ignition tip can be brought up to 1 minute by original 5 minutes, so just can save a large amount of time for the production of.Adopt in this way simultaneously, the replacing that operating personnel carry out ignition tip outward at station is also safer, personnel need not enter in safe fence, can avoid like this personnel to enter deathtrap, operating personnel's personal safety is better ensured, and only have in the time that control button is pressed, robot body just can be delivered to soldering turret outside safe fence automatically, more ensures safety.And operating personnel have reduced operating personnel's labour intensity without walking up and down.And by the position degree deviation of track correction verification module detection ignition tip, avoid the batch weld excursion that send the deviation of welding wire to cause due to ignition tip.To realize expense lower for this system simultaneously, every cover system hardware cost is no more than 1000 yuan, and cost of labor is also 1000 yuan of left and right, but long-term value is obvious, average two classes of productions every day (changing 2-3 ignition tip with per tour calculates) can be produced 16-24 more and be divided kind, and some months can be recouped capital outlay.
In sum, while adopting the present invention to carry out the ignition tip replacing on arc-welding welding gun, robot body can be sent station by welding gun, the ignition tip that operating personnel get final product Butt welding gun in station outside is like this changed, and in safe fence, carry out ignition tip replacing without entering into again, make like this operating personnel's personal safety better be ensured, simultaneously also shortened operating personnel and change the time of ignition tip, accelerated operating efficiency.And detect the position degree deviation of ignition tip by track correction verification module after ignition tip has been changed, and avoid the batch weld excursion that send the deviation of welding wire to cause due to ignition tip, ensure welding quality.So the present invention has effectively overcome various shortcoming of the prior art and tool high industrial utilization.
Above-described embodiment is illustrative principle of the present invention and effect thereof only, but not for limiting the present invention.Any person skilled in the art scholar all can, under spirit of the present invention and category, modify or change above-described embodiment.Therefore, such as in affiliated technical field, have and conventionally know that the knowledgeable, not departing from all equivalence modifications that complete under disclosed spirit and technological thought or changing, must be contained by claim of the present invention.
