Background technique

Welding wire layer winding machine is a kind of equipment that regularly winds the processed finished welding wire layer by layer on the welding wire reel for packaging, storage, circulation and sales. The welding wire obtained through welding wire layer winding is several kilograms per reel To tens of kilograms, easy to circulate and use, it is the last process of welding wire production. The welding wire layer winding process is generally divided into the following steps. First, the starting end of the welding wire needs to be bent to form a hook shape, hook it to the gap on the wire reel, and then turn the wire reel to wind the welding wire onto the wire reel. Each layer The welding wire rings are closely arranged between the rings, and the next layer is wound after one layer is filled until the specified weight or length is reached. Finally, the welding wire needs to be cut off, and its end is passed through the small hole on the wire reel, and folded Bend to prevent the wound wire from falling apart.

The current level of automation of welding wire layer winding machines is not high, the main reason is that it fails to solve three key problems: First, at the beginning, the beginning of the welding wire is automatically bent into a hook shape and hooked onto the wire reel, which is called "hooking". The second is that during the layer winding process, it is automatically ensured that each layer of welding wire is closely arranged with the welding wire of the adjacent circle when winding, and there is no gap or overlap, which is called "tight layer winding"; the third is that in the layer At the end of winding, the welding wire is automatically cut off, and the end of the welding wire is passed into the corresponding hole on the wire reel and automatically bent, which is called "final hook wire".

Lift the rollers (352A, 352B); the welding wire reel position camera on the lifting part 3 takes the welding wire reel 11 image, recognizes the position of the dial hole 11B on the welding wire reel 11, and drives the lifting roller (352A) through the lifting roller drive motor 354 , 352B) drive the welding wire reel 11 to rotate to a suitable position, then lift the cylinder 34 to raise the lifting frame 351, so that the central hole 11A of the welding wire reel 11 is coaxial with the main shaft 42; the pressure plate 55 of the tailstock part 5 promotes the welding wire reel 11 Close to the main shaft 42, the main shaft 42 is inserted in the central hole 11A of the welding wire reel 11 and the driving rod 422 on the dial 421 is inserted into the dialing hole of the welding wire reel 11, and kept pressed; the rotation of the main shaft 42 makes the hook wire hole on the welding wire reel 11 Facing the wire feeding conduit 68, the wire feeding conduit 68 drives the welding wire 12 close to the welding wire reel 11, and sends the welding wire 12 into the hook wire hole on the welding wire reel; the lifting wire mechanism 44 passes through the arc-shaped hole on the dial 421 , the main shaft 42 drives the welding wire reel 11 to rotate, and the welding wire 12 that passes through the wire reel 11 to hook the wire hole is blocked by the starting wire head of the wire pressing mechanism when rotating, and then bent to form a hook shape, hooked on the wire reel 11 On the wire hooking hole, the wire pressing mechanism 44 exits, the main shaft 42 rotates, the welding wire 12 starts to wind on the wire reel 11, and the wire feeding guide 68 is controlled to make the welding wires closely arranged for layer winding; after the layer winding meets the requirements, the spindle 42 stop the rotation, the wire folding part 8 moves to a suitable position, the wire pressing head 883 on the wire folding fixed arm 881 and the bending arm wire pressing head 894 on the bending arm 892 press the welding wire 12; The wire cutting part 7 moves to a proper position, the wire cutting mechanism 74 cuts the welding wire; the bending arm 892 rotates and bends the welding wire, and loosens the welding wire, and the folding wire fixing arm 881 drives the end of the welding wire to move to the welding wire fixing hole 11E on the welding wire reel 11 place, and make the end of the welding wire pass through the hole; the final pressing wheel (452, 453) presses the end of the welding wire to the wall of the wire reel, so that the end of the welding wire hooks the fixing hole; the push ring (46A, 46B) of the translational push-out mechanism pushes the The welding wire reel after winding the welding wire is released from the main shaft 42 and falls on the lifting rollers (352A, 352B). The shift push rod 105 releases the welding wire reel from the lifting frame and enters the welding wire reel discharge chute 9.

It should be noted that, according to the principle proposed by the present invention, there are many specific implementation examples. For example, the shifting part can be installed on the workbench instead of being installed separately. For another example, the movement of the shifting part can be replaced by a cylinder. The rack and pinion mechanism in the machine and so on.

In addition, the fully automatic welding wire layer winding machine based on the principles of the present invention can be applied to other similar workplaces, for example, winding the processed enameled wire or other types of wires to the I-shaped reel similar to the welding wire reel, the winding reel For other applications of the automatic welding wire layer winding machine based on the present invention, it should be within the protection scope of the present invention.
