Welding control system.The reconditioning of electrode is counted generally in robot control unit by the robot welding system of these brands.
The electrode of robot soldering pliers carries out reconditioning after welding certain number of times, and its resistance of the electrode after reconditioning is inevitable also there occurs change,
Use the welding parameter originally set, welding quality will necessarily be affected.
Summary of the invention
The present invention devises the welding reconditioning compensation method of the automobile body welding equipment of a kind of auto industry, its technology solved
Problem is that the electrode of existing robot soldering pliers carries out reconditioning after welding certain number of times, and its resistance of the electrode after reconditioning is inevitable also to be sent out
Give birth to change, used the welding parameter originally set, welding quality will necessarily have been affected.
In order to solve the technical problem of above-mentioned existence, present invention employs below scheme:
The welding reconditioning compensation method of the automobile body welding equipment of a kind of auto industry, comprises the following steps:
Before the work of step 1, coping device, gather soldering turret welding times coherent signal by bus and send to welding controller I/O
Plate, is reconverted into machine code and carries out Data Comparison with single-chip microcomputer inner setting program；When soldering turret welding times reaches reconditioning meter
During the setting value counted, welding controller can send reconditioning request, and polishing device can carry out reconditioning to electrode, it is to avoid same electrode cap
Disposable welding is counted and is too much affected welding quality, and this both can ensure that welding quality can avoid defective solder joint to omit simultaneously；
Step 2, startup reconditioning switch so that coping device is started working and electrode cap surface is carried out reconditioning；
After step 3, coping device complete reconditioning to electrode cap 1b, needing to carry out electrode cap 1b heat compensation, heat compensation is mended
Fill mode as follows: heat compensation sets when welding procedure is arranged, automatically start after electrode cap reconditioning；According to formula Q=
I2Rt, Q are sweating heat value, and I is welding current, and R is the resistance value of electrode, and t is weld interval；Carry out heat Calculation, work as electricity
After the resistance R of pole reduces, it is desirable to value Q is constant for sweating heat, so needing by increasing welding current I or t weld interval
Carry out heat compensation.The welding reconditioning compensation method of the automobile body welding equipment of this auto industry has the advantages that
The present invention is by when using welding controller to carry out reconditioning counting, using specific coping device to carry out electrode cap surface simultaneously
Reconditioning, finally can use heat compensation function, it is ensured that quality of welding spot.

Detailed description of the invention
Below in conjunction with Fig. 1 to Fig. 5, the present invention will be further described:
As it is shown in figure 1, the automobile body welding equipment of a kind of auto industry, door lock 1 and Xiamen on cabinet door is respectively arranged at two ends with up and down
Lock 2.Rotary switch 3 is to select craft or robot welding.
As in figure 2 it is shown, the automobile body welding equipment of a kind of auto industry, it is provided with radiator 3 in the bottom of cabinet one side
Air outlet.
As it is shown on figure 3, the automobile body welding equipment of a kind of auto industry, a side of cabinet is concentrated and is provided with main power source
Incoming line the 5, first soldering turret long cable section of ingoing line 9, signal cable wire-threading device the 6, first soldering turret signal wire interface the 7, second soldering turret holding wire
Interface 8 and the second soldering turret long cable section of ingoing line 10.First soldering turret long cable section of ingoing line 9 is connected with the first soldering turret, the second soldering turret long cable section of ingoing line
It is connected with the second soldering turret.
As shown in Figure 4, inside its cabinet, it is provided with four-layer structure, is respectively as follows: ground floor from top to bottom and is provided with control loop electricity
Source terminal row 11 and PLC12, the second layer prolongs horizontal direction and is followed successively by reconditioning switch 13, solid-state directional contactor 15, relay 16
And main power source catalyst 14, third layer is set to grounding copper bar 17, and third layer is prolonged horizontal direction and is followed successively by controller 18 and exchanges
Catalyst 19.
As it is shown in figure 5, coping device is by dressing 1a, sorption wheel 1c, absorption air channel 1d, the first motor 1e, the second motor 1f
And the 3rd motor 1g, the first motor 1e drive dressing 1a to rotate, the second motor 1f drives the electrode cap 1b of soldering turret to rotate, the
Three motor 1g drive Electrostatic Absorption wheel 1c to rotate, dressing 1a and electrode cap 1b in mutual friction process by electrode cap 1b surface
Oxide and gel-like foreign matters abrasion become granule, granule is taken turns by the Electrostatic Absorption below at dressing 1a and electrode cap 1b friction
