People, which reproduces in operation process, there is certain failure, the computer system of spot welding robot just autostop after signal an alert,
And show the type of error or fault.Spot welding robot has the interface with external device communication, it can pass through this interface
Receive upper level master control and works with the control command for managing computer.
One auto parts assembly be by numerous, big and small assembling parts together, each part has assembly
Arrange order, substep corresponding assembling parts together.The welding overwhelming majority of auto parts assembly is by spot welding robot
It completes, spot welding robot is firstly moved to the solder joint position of part at work, and then welding gun turn-on current completes welding, next
Spot welding robot will continue to be moved to next solder joint position, and galvanization is welded welding gun again.Spot welding robot is welding
On production line, spark splash it is larger, be then attached on vehicle body, need staff expend considerable time and effort could incite somebody to action
It is polished off, and causes serious energy waste, the problems such as car body quality is bad.
Therefore those skilled in the art are dedicated to developing a kind of method that reduction spot welding robot's spot welding spark splashes, with solution
The technical issues of certainly spark splashes when spot welding robot's spot welding.
Summary of the invention
In view of the above drawbacks of the prior art, the technical problem to be solved by the present invention is to fiery when spot welding robot's spot welding
Flower splashes, and the present invention provides a kind of method that reduction spot welding robot's spot welding spark splashes.
To achieve the above object, the present invention provides a kind of methods that reduction spot welding robot's spot welding spark splashes, including
Following steps:
1) guarantee that the gap between component and soldering turret stationary electrode to be welded is 0 to 5 ㎜；
2) coping device stability confirmation.
Preferably, the gap between component to be welded and the soldering turret stationary electrode is 0 ㎜；White three coordinate measurement qualification rate of car body
It maintains to stablize.
Preferably, welding institute calorific requirement Q, the relationship between conduction time T, resistance R are as follows: Q=I2RT, wherein resistance R
=R1+R2,R1For the parts to be tested resistance, R2For contact resistance.
Preferably, coping device setting is in the component side to be welded and is fixedly mounted on the ground.
Preferably, being also included the following specific steps before step 1):
1) the bonding state confirmation of the component to be welded；
2) the spot welding parameter setting of the spot welding robot.
Preferably, the gap between component to be welded is 0~5 ㎜.
Preferably, the gap between component to be welded is less than 1 ㎜.
Preferably, spot welding robot can have multiple solder joints.
Preferably, being that welding parameter is separately provided in each solder joint in step 2).
The beneficial effects of the present invention are:
1) present invention guarantees that the gap between component and soldering turret stationary electrode to be welded is 0 to 5 ㎜, component to be welded and soldering turret electrostatic
The distance between pole is smaller, and contact area can reduce, contact resistance be it is smaller, the heat of generation is also smaller；Component to be welded with
The distance between soldering turret stationary electrode is bigger, and contact area can contract greatly, contact resistance be it is bigger, the heat of generation is also bigger.Institute
With when the distance between second component and soldering turret stationary electrode are zero, contact area can be minimum, and contact resistance is minimum, generation
Heat is minimum, can reduce heat to greatest extent, and spark splashes when reducing spot welding robot's spot welding to greatest extent, and not shadow
Ring the welding function of spot welding robot.
2) gap between component to be welded involved by the present invention is 0~5 ㎜, and the gap between component especially to be welded is less than 1
㎜, under same welding condition, part overlaps that gap is smaller, and when spot welding robot's spot welding is less susceptible to spark splashing, avoids making
At energy waste, car body quality is bad and personnel, waste of time.
3) welding parameter is separately provided when carrying out parameter setting to spot welding robot for each solder joint in the present invention,
Not in such a way that several solder joints share set of parameter, other welderings can be influenced to avoid the adjustment because of single spot welding parameter in this way
Point.
4) present invention ensure that the stability of coping device, shaking when can repair a die to avoid coping device, when leading to two electrode weldings
Dislocation, spark splashes when spot welding robot being caused to weld.
5) present invention keeps white three coordinate measurement qualification rate of car body to stablize, as long as the program about spot welding robot is constant
Change, the position that spot welding robot welds every time is stable, fire when can further avoid spot welding robot's spot welding in this way
Flower splashes.
