Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is expanded on further。These embodiments are interpreted as being merely to illustrate the present invention rather than limiting the scope of the invention。After having read the content that the present invention records, the present invention can be made various changes or modifications by those skilled in the art, and these equivalence changes and modification fall into the scope of the claims in the present invention equally。
As Figure 1-3, the planer-type solar array resistance spot welding lathe that the preferred embodiment of the present invention provides, lathe entirety adopts aluminum alloy materials to build, including bed piece 1, image identification unit 2, single axis robot 3, program control welding unit 4 (AVIO:MCW-750), pressure control unit 5 (AVIO:QC-100), control rack and operation software thereof, wherein: the framework of bed piece 1 adopts aluminium alloy extrusions to build；X-axis adopts the section material guide rail that two Timing Belts drive, and two guide rails are distributed in the both sides up and down of lathe, adopts synchronizing bar between two guide rails；Y-axis adopts a Timing Belt to drive aluminium alloy extrusions guide rail and an auxiliary aluminum alloy profile guide rail；Platen is arranged on the slide block of Y-axis；Z axis adopts single axis robot 3, and is arranged on platen；Image identification unit 2, program control welding unit 4 and pressure control unit 5 are installed on platen；Image identification unit 2, program control welding unit 4 and pressure control unit 5 all and control rack communication connection；The operation Integrated Simulation controlling rack has the module controlling integrated image identification unit 2, program control welding unit 4 and pressure control unit 5；The X-axis of lathe, Y-axis and Z axis all adopt servomotor。
The planer-type solar array resistance spot weld of the present embodiment has image recognition, automatic tracking location function, this function mainly by form the pick-up lens of image identification unit 2, calibrating device and control rack and operation software complete。This function can help lathe to carry out being accurately positioned of bond pad locations, and precision can reach ± 0.05mm。
The planer-type solar array resistance spot weld of the present embodiment has welding pressure and controls function。The QC-100 pressure control unit of the integrated AVIO of this lathe。In control rack and operation software thereof, design special module carry out integrated, use it to complete the monitor in real time of welding pressure, and be subjected at the pressure spot set。
The planer-type solar array resistance spot weld of the present embodiment has program control welding function。Miniature microgap parallel resistance spot welding unit (MCW-750) of the integrated AVIO of this lathe。By relevant interface and agreement, controlling rack and operation software users just can complete the setting of the important parameters such as welding current, voltage, discharge time, and it is welded in real time curve (electric current, voltage) be monitored and data acquisition。The photo simultaneously using field terminal unit to take, completes preserving in real time and monitoring all data of each solder joint。
Owing to the lathe of the present embodiment is used for welding solar array, its weight is very light, so the framework of bed piece 1 adopts high-quality aluminum alloy section bar to build；X-axis adopts the section material guide rail that two Timing Belts drive, and two guide rails are distributed in the both sides up and down of lathe, adopts synchronizing bar to ensure the synchronicity of its motion between two guide rails。Y-axis adopts a Timing Belt to drive aluminium alloy extrusions guide rail and an auxiliary aluminum alloy profile guide rail；Platen is arranged on the slide block of Y-axis, all adopts aluminum alloy materials；Z axis adopts single axis robot 3, is arranged on platen, and its structure is extremely compact, easy to control。
As it is shown on figure 3, the monitor controller etc. of the welding gun of the photographic head of image identification unit 2, program control welding unit 4 and power supply, pressure control unit 5 is all arranged on platen, on lathe, all of cable is all completed by trough。Whole lathe all adopts aluminum alloy materials to build, and light structure, lightweight, outward appearance is generous attractive in appearance。
The method that lathe completes solar array resistance spot welding is illustrated below in conjunction with accompanying drawing:
What X, Y, Z of lathe adopted is servomotor, it is possible to complete welding gun accurate control of position on platen。What control rack operates the Integrated Simulation module of image identification unit 2, program control welding unit 4 and pressure control unit 5 etc.。
During welding, first solar array is fixed on lathe table top。Then dead-center position and the dimensioned area of solar array are set for unit。
After setting completes, pressing beginning recognition button, unit will according to the dead-center position of cell array and dimensioned area, automatic operation image recognizer。The operation software of control rack can control the photographic head of image identification unit 2 and be scanned taking pictures and identifying to whole cell array, in the component locations information to be welded transmission storage identified to data base。
After identification completes, it is necessary to weld required voltage (or electric current), discharge time and curve etc. according to the different set of welding component；And the pressure needed during welding。Setting completes to press and starts to weld button, and the single axis robot of Z axis moves to components and parts to be welded with welding gun under program control, now the pressure of lathe monitor in real time welding gun, after reaching setting value, feed back signal to control rack, stop Z axis and move, and give one enabling signal of the source of welding current。The source of welding current welds under the triggering of signal, and now unit can gather the parameter that welding is relevant automatically, and monitoring unit takes photo during welding, and they are stored in data base。
Lathe repeat the above steps, until monoblock solar array has welded。
