Description

Technical Field

[0001] The present invention relates to the technical field of welding processing equipment, and in particular to welding processing equipment for producing and processing LED lighting lamps. Background Art

[0002] LED (light-emitting diode) lighting is a type of lighting fixture made using fourth-generation green light sources, LEDs. Known as fourth-generation lighting sources or green light sources, LEDs offer advantages such as energy saving, environmental friendliness, long lifespan, and compact size. They are widely used in various fields, including indication, display, decoration, backlighting, general lighting, and urban nightscapes. In the production and processing of LED lighting, welding is a core step in determining the product's structural stability, electrical performance, and appearance quality. This is particularly true for the connections of key components, such as lampshades, lamp panels, and lamp holders, where requirements for welding precision, efficiency, and compatibility are becoming increasingly stringent.

[0003] The structure of LED lighting is becoming more diversified. Take conical lampshades as an example. Since conical lampshades come in different sizes and tapers, existing welding equipment is prone to uneven welds or cold welds due to loose contact when welding conical structures of different tapers. In addition, the clamping mechanism of the welding equipment is mostly rigidly fixed, which is difficult to accommodate the curved surface clamping requirements of thin-walled materials, and surface scratches or deformation are common.

The inner supporting component can offset the expansion tendency of the conical lampshade when subjected to internal pressure, while the outer fixing component can limit the shrinkage deformation caused by external extrusion, thereby forming a two-way constraint, effectively resisting radial loads, and avoiding failure phenomena such as bulging and denting of the cylinder wall.

At this time, multiple arc plates 761 can form multi-point clamping for different curvature positions of the conical lampshade, tightly fitting the outer surface of the lampshade, effectively limiting its displacement or deformation caused by heat and force during welding. The motor 72 is connected to an external power supply to work, and the motor 72 drives the circular plate 75 and the connecting plate 73 to rotate, so that the arc plate 761 drives the internal conical lampshade to rotate around the round rod 78, so that the longitudinal straight line weld of the conical lampshade is located on the vertical plane, ensuring that the petals on both sides of the weld are at a preset conical angle before welding, avoiding the longitudinal straight line The weld seam is offset or twisted, and a circular plate 75 is fixedly connected to the middle of the side of the connecting plate 73 away from the fixed plate 71.

[0022] According to the inner wall diameter size of the conical lampshade, the square block 58 drives the trapezoidal block 54 to slide inside the square hole 53, so that the trapezoidal block 54 moves to the specified position, so that multiple trapezoidal blocks 54 form a circular outer diameter that is the same as the inner wall diameter size of the small diameter of the conical lampshade. Then the sliding plate 9 at the bottom of the vertical plate 51 drives the trapezoidal block 54 close to the conical lampshade, so that the trapezoidal block 54 is located inside the conical lampshade. The elastic properties of the trapezoidal plate 55 are used to make the positioning plate 56 fit the inner wall of the conical lampshade. As the sliding plate 9 continues to move, the limiting plate 57 contacts the large-diameter end of the conical lampshade, and then pushes the other end of the conical lampshade to contact the baffle 763, thereby axially limiting the conical lampshade.

[0023] After the workpiece is fixed, the electric push rod 62 works to push the welding gun 63 and the fixing seat 64 close to the bottom of the workpiece, so that the contact plate 68 fits the outer side of the workpiece. The elastic force of the return spring 65 can make the contact plate 68 always fit closely to the surface of the workpiece. After positioning, the slider 61 drives the welding gun 63 to move along the straight weld seam of the conical lampshade for welding.
