Referring to fig. 4 to Fig. 7, consider from solder joint position, selects welding gun model SRTX-2C7636-LX4, SRTC-
2C5776LX2, SRTC-2C5777LX2, SRTX-2C7635-LX5.
Cabinet body and bottom plate welding sequence: passing in and out rifle path to the design and simulation of special-shaped true welding gun, design welding gun according to cabinet body,
Disengaging rifle ensures to pass in and out rifle in 210 practical 185mm of welding gun designed openings maximum or so and does not interfere tooling and cabinet body, to realize weldering
The welding of point.
Welding beat is optimized: time longer process solder joint is moved into his sequence to realize the mesh for evenly distributing solder joint
, express delivery cabinet welds beat 120 seconds, this programme is such as applied to rich nest cabinet body, then beat is modified to 150 seconds.
Limit solder joint carries out spot-welded: posture limit when because of solder joint robot welding, so 1 axis of positioner is rotated
45 ° are welded.Such as: two repair welding solder joints of cabinet body guiding gutter inboard cannot achieve welding, and an axis, which turns to 45 °, can be achieved weldering
It connects.
In terms of PLC.
Welding interference problem: welding equipment with welding procedure point distribution and require it is different, throughout the region that is entirely welded,
So it is ubiquitous to weld bring electromagnetic interference itself.
Efficiently use bus cable and feed cable shielded layer function of shielding.Bus cable is generally mostly to shield electricity
Cable, Fraquent start, the drive apparatus for changing frequency generally can also select shielded cable.In type selecting, reliable cable is selected, is guaranteed
The integrality of shielded layer.
Drive apparatus interference problem: drive apparatus generates a large amount of high-frequency electromagnetic in starting and stopping, operation and speed regulation process
Wave forms interference, pollutes neighbouring field control system.
It installs hardware additional and considers wave circuit, the occasions power loop such as Fraquent start, frequency conversion installs the filter of the hardware such as input and output reactance additional
Wave circuit reduces main power source harmonic wave, surge and peak point current, meanwhile, improve the anti-interference of control system, safeguards system it is steady
It is fixed.Such as: in main control cabinet, i.e., the HT2320-3-L8-H1 power-supply filter of access Hui Bodun realizes main control cabinet electricity in MPC cabinet
The filtering in source.The CW4L2-30A-R filter that OMNICOM is accessed in positioner control cabinet, realizes the filtering of drive apparatus.
Power cable interference problem: nearest power-equipment for example: the confession of welding transformer, air cleaning system motor etc.
Electrical cables, because power plant power is big, rated current is high, and immediate current may be up to 6-the 11 of rated current when especially starting
Times, because face can generate big rush of current in the short time.
Take method are as follows:
1, bus apparatus is laid with far from interference source, bus cable with power cable respectively.Control the power-equipment and electric power at scene
Cable square is inversely proportional to the interference size of fieldbus and distance, i.e., distance is bigger, and interference attenuation is faster.So live
Bus apparatus will be as far as possible far from power-equipments such as motor, transformers；
2, bus cable laying is laid with respectively with power cable, at least accomplishes to be layered gantry arrangement.
3, the suitable communication speed of setting.Fieldbus networks total length and communication speed have inversely, usual net
Network total length is longer, and communication speed needs drop lower.
4, repeater in installing additional, amplifies network signal, extends network length；Using fiber optic communications；Control system and cable
Arrangement is laid with and combines with technique.
Power supply system interference problem: power frequency supply wave distortion and higher hamonic wave are isolated or are considered wave if not adding, can pass through confession
Electric system face metering-in control system rings whole scene bus from face.
Install isolating transformer, regulated power supply additional.While preventing the interference from power frequency supply, reduce current supply circuit due to
The unstable bring interference of power supply.
Instability problem caused by imperfect earth: reliable ground.Guarantee equipment normal work and personal safety, inhibits simultaneously
Electromagnetic interference.The ground connection of fieldbus is divided into single-point grounding and multipoint earthing.Under normal circumstances, working frequency is in 1MHZ or less
When, single-point grounding can be used.Such as: when using shielded cable low-frequency transmission signal, by the screen of the shielding of each branch line and main line
It covers and links together, finally converge and be grounded (i.e. single-point grounding).It determines line standard according to low frequency scene, whole cable
Upper only to allow one point earth, any one end of bus does not allow to be grounded, and shielded layer cannot be as power supply line.When field of line bus works
Multipoint earthing can be used in 10MHZ or more in frequency, can also two kinds of earthing modes be used in mixed way, concrete condition should be according to selected
Fieldbus characteristic and engineering is practical is designed.
In terms of production line detailed design:
