TECHNICAL FIELD
[0001] The present application relates to the technical field of electric welding device, in particular to an electric welding device for electronic component manufacturing. BACKGROUND
[0002] Electric welding refers to a welding method that uses electric energy to heat or pressurize, or both, and uses or does not use filler material to make the welding piece reach atomic bonding. When manufacturing electronic components, a welding gun is usually used to heat the welding wire to achieve the effect of electric welding. Generally, electric welding devices are divided into full-automatic electric welding machines, semi-automatic electric welding machines, and manual electric welding machines. Full-automatic electric welding machines have high efficiency in manufacturing industry, but require high artificial operation, and need to be programmed and adjusted by a dedicated person to make the running track meet the welding position of electronic components, and manual feeding and discharging are also required, which is costly. Semi-automatic electric welding devices are simple to operate and do not require programming, so the requirement for programming personnel is low. In the work, the worker holds the electronic component in one hand and the electric wire in the other hand, and then steps on the control switch to make the electric push rod push the welding gun down to weld. In most small electronic factories, considering the cost, semi-automatic electric welding devices are usually used. However, most existing semi-automatic electric welding devices have a common problem that the welding fume needs to be sucked by an independent pipeline. However, the arrangement of the pipeline easily limits the use of the welding gun and the welding wire, so most semi-automatic spot welding devices do not have a welding fume suction device in production. Some factories independently install the device, but some factories do not equip the device to save trouble, which easily causes damage to the workers. SUMMARY

[0017] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0018] See also Figures 1-10 , an electric welding device for manufacturing electronic components, comprising a base 1 and a console 2 and a top frame 3 mounted thereon, a wire rack 71 being fixedly mounted on the side wall of the top frame 3, and further comprising: The friction wheel 72 is rotatably mounted on the side wall of the top frame 3; A fixed tube 82, which is fixedly mounted on the side wall of the top frame 3 and is used for the welding wire to pass through; A hose 83 , one end of which is connected to the fixed tube 82 and the other end of which is directed toward the welding gun 6 ; The expansion tube 81 is installed between the fixed tube 82 and the top frame 3. The expansion tube 81 and the fixed tube 82 are connected, and the fan blade 76 is installed in the expansion tube 81; The vertical plate 91 has toothed plates 91.1 rotatably mounted on both side walls thereof. A rotating wheel 73 cooperating with the toothed plates 91.1 is fixedly mounted on each of the two friction wheels 72. The downward movement of the vertical plate 91 drives the rotating wheel 73 to rotate, while the upward movement of the vertical plate 91 does not drive the rotating wheel 73 to rotate. The vertical plate 91 is moved downward to drive the two friction wheels 72 to rotate inward, thereby sliding the welding wire on the wire rack 71 downward. At this time, the other end of the welding wire will extend from the surface of the hose 83 to facilitate welding. When welding is completed, the vertical plate 91 moves upward, which will drive the fan blades 76 to rotate, so that the hose 83 generates suction to suck the welding smoke into the hose 83.
[0019] In another embodiment of the present invention: the vertical plate 91 is located between the two rotating wheels 73, and the rotating wheels 73 are provided with a plurality of tooth grooves along their circumferences; Among them Figure 10 As shown, the right-angled bottom end of the tooth plate 91.1 can rotate downward on the surface of the vertical plate 91, so that when the vertical plate 91 moves downward, the tooth plate 91.1 remains horizontal. At this time, the vertical plate 91 will drive the rotating wheel 73 to rotate through the tooth groove of the rotating wheel 73, and because the vertical plate 91 is located between the two rotating wheels 73, the downward movement of the vertical plate 91 will drive the two rotating wheels 73 to rotate inward toward each other. The welding wire is installed in the wire rack 71 after being rolled, and the welding wire passes between the two friction wheels 72 into the fixed tube 82. Therefore, when the two rotating wheels 73 drive the two friction wheels 72 to rotate inward toward each other, the welding wire between the two friction wheels 72 will be pushed to slide downward.

When the riser 91 descends, the pulleys drive the rotating wheel 73 to rotate. When the riser 91 ascends, the pulleys rise freely without driving the rotating wheel 73 to rotate. The shaft 77 is in close contact with the side wall of the vertical plate 91, and when the vertical plate 91 moves, the shaft 77 rotates, and the shaft 77 drives the connecting shaft 75 and the fan blade 76 to rotate through the belt 74. When the vertical plate 91 rises, the rotating direction of the fan blade 76 generates suction, and the suction is generated in the fixed tube 82 and the hose 83 to absorb the welding fume.

The bottom end of the vertical plate 91 is fixedly installed with a bottom plate 92, the bottom plate 92 is fixedly installed with a convex strip 94, and the second sliding ring 96 is fixedly installed with an inclined rod 95. The telescopic cover 88 is provided with a plurality of telescopic covers, four telescopic covers 88 are provided in the embodiment, the four telescopic covers 88 are combined to form a cone, and the welding wire extends from the tip of the combined telescopic cover 88, so that the combined telescopic cover 88 limits the welding wire to avoid large left and right deviation angles. The bottom end of the convex strip 94 is provided with an inclined edge, the inclined edge is in close contact with the inclined angle of the inclined rod 95, when the vertical plate 91 rises, the convex strip 94 rises through the bottom plate 92, and the inclined edge pushes the inclined rod 95 to move left (refer to Figure 5 ) along with the rising of the convex strip 94, the inclined rod 95 drives the second sliding ring 96 to move along with the movement of the second sliding ring 96, the first sliding ring 97 drives the first sliding ring 97 to move through the connecting rod, the first sliding ring 97 pulls the convex plate 86 to rotate through the string 85, the rotating of the convex plate 86 drives the rotating block 87 and the telescopic cover 88 to rotate, the plurality of telescopic covers 88 are opened outward, the through hole 89 of the fixed head 84 is exposed, and the suction in the hose 83 is absorbed through the through hole 89 to absorb the welding fume. The rotating block 87 and the fixed head 84 are installed with a coil spring, when the string 85 no longer pulls the convex plate 86, the coil spring drives the rotating block 87 to rotate and reset, so that the plurality of telescopic covers 88 rotate and reset to be combined, the combined telescopic cover 88 limits the welding wire again to avoid that the size of the through hole 89 is too large to affect the accurate positioning of the welding wire. The inner diameter of the hose 83 is larger than the size of the welding wire, so that the welding fume can pass through. The hose 83 is a shaped hose 83.
