The invention discloses an automatic welding device for a solar junction box. The automatic welding device comprises a body, a horizontal workbench and a lifting frame, wherein at least one group of tin feeding mechanism and corresponding soldering heads are fixedly arranged on the lifting frame; the soldering heads are controlled by a heating device; a bending mechanism used for pressing a bus-bar on a solar panel into a binding post of the solar junction box is arranged on the horizontal workbench; a transversally moving mechanism is arranged between the horizontal workbench and the body; a lifting mechanism is arranged between the workbench and the lifting frame; the heating device, the bending mechanism, the tin feeding mechanism, the transversally moving mechanism and the lifting mechanism are controlled by a PLC (programmable logic controller); and a locating mechanism is arranged on the bottom surface of the body. According to the automatic welding device for the solar junction box, original manual welding is replaced by automatic welding, not only are the welding quality and production efficiency improved, but also accurate welding is achieved through arrangement of the locating mechanism, and additionally, multi-station welding can be achieved through arrangement of the transversally moving mechanism and the lifting mechanism.

PURPOSE: To improve an efficiency and safety as well by vertically locating the box column loaded on a raising and felling device and by performing an automatic welding of a diaphragm by using the traveling type welding machine arranged on the lift of a portal frame. CONSTITUTION: The frame 17 ascending and descending along a main column 1 and the automatic welding machine moving in the horizontal direction along the main beam of the frame 17 are provided on the front face of the portal frame composed of a pair of main column 11 and sub-column 12 and plural work platform supporting frame 14. A box frame 30 is then raised by actuating a driving device 32 after binding by horizontally loading plural box columns 1 on the box frame which is located at the horizontal position. With the vertical standing of the box column 1 the prescribed welding is performed after positioning the automatic welding machine by driving the frame 17 further by advancing the work platform 15 located on the supporting frame 14 according to the position of the diaphragm 2 to be welded. The box column can thus be safely welded with good efficiency. COPYRIGHT: (C)1987,JPO&Japio

PURPOSE:To weld a rod member easily with high strength by placing the rod member in the almost same shape groove of a copper strap so as to pinch a deeper groove of the center part, arc-dissolving alternately the center lower part by a CO2 half-automatic welding machine, forming the first layer, and therefore, heaping it up in the shape of a ring CONSTITUTION:Rod members 1A, 1B are placed in the almost same shape groove 2a of a copper strap 2 so as to pinch a deeper groove 2b of a welding operable width of the center part The section center lower part of the rod member 1A is arc-dissolved 4 by a flux-contained wire 3 of a CO2 half-automatic welding machine, the section center lower part of the rod member 1B of the opposite side is arc-dissolved 4, and the first layer 4 of the lower part is formed by repeating said operation The second layer and its subsequent layers are dissolved and heaped up in the shape of a ring, and in the end, dissolved and formed in a sectional shape of the rod members 1A, 1B In this way, the rod member is welded with high strength by a simple method

PURPOSE:To improve the operability in a one face welding by lowering the supporting height of the material to be welded and by disusing an end tab, by binding to the material to be welded via a pressing plate the backing material somewhat longer than the length of the one face butt weld zone of short sized body. CONSTITUTION:The backing material 3 somewhat longer than the weld zone 2 length is fastened by a speed clamp 8 at its four corners via a pressing plate 5 in the one face butt welding of a short sized body 1. In this case, the height (h) of the supporting angle 11 of the material 1 to be welded is taken less than about 100mm. The operability in the one face welding can be increased owing to no end tab of the weld zone 2 terminal being necessary.
