Technical Field

[0002] Thermocouple wire welding is a process that uses the heat generated by thermocouple wire to transfer heat energy to the objects to be connected for welding. Thermocouple wire generates heat when it is energized. The heat is transferred to the surface of the objects to be connected through heat conduction. The heat acts on the surface of the objects to be connected, causing the connected parts to melt and fuse, thereby completing the welding.

[0019] Step 2: The wire and material to be welded are transported to between the two clamps of the material receiving mechanism through the first feeding device and the second feeding device, and then the third electric cylinder is used to drive the moving block to move, and the movement of the moving block drives the connecting arm to deflect, and the scissors hingedly connected to the other end of the connecting arm deflect around the bottom end of the fixed bracket accordingly, and the welding wire is cut through the deflection of the two scissors, and then the second electric cylinder is used to drive the second central axis to rotate, and the rotation of the second central axis drives the second turntable to rotate, and the rotation of the second turntable drives the second cylinder to rotate, and the moving bracket of the outer ring of the second cylinder moves along the sliding rod accordingly, so that the clamps on the two moving brackets move toward each other, and the wires and logistics on the clamps of the two material receiving mechanisms then fall from the clamps and adhere to the tape below them;

[0020] Step 3, using a motor to drive the first rotating shaft to rotate, the rotation of the first rotating shaft drives another first rotating shaft whose end is connected through the first hinge seat, the second hinge seat, the sleeve and the sleeve shaft to rotate accordingly, and then the first rotating shaft and the second rotating shaft are connected through a synchronous belt and a synchronous wheel transmission connection to make the second rotating shaft rotate accordingly, and the rotation of the second rotating shaft drives the threaded column at its end to rotate, thereby moving the tape to transport the wire and material thereon, and when the wire and material are transported to the welding mechanism, the ends of the wire and material can contact each other;

[0058] Step 3, use a motor to drive the first rotating shaft 205 to rotate, the rotation of the first rotating shaft 205 drives another first rotating shaft 205 whose end is connected through the first hinge seat 207, the second hinge seat 210, the sleeve 208 and the sleeve shaft 209 to rotate accordingly, then the first rotating shaft 205 and the second rotating shaft 206 are connected through a synchronous belt and a synchronous wheel to make the second rotating shaft 206 rotate accordingly, the rotation of the second rotating shaft 206 drives the threaded column 212 at its end to rotate, and then the tape moves to transport the wire and material thereon, and when the wire and material are transported to the welding mechanism 5, the ends of the wire and material can contact each other;

[0061] Working principle: When the present invention is in use, the positions of the rollers 217 on the two lifting brackets 214 are adjusted by moving the lifting brackets 214, and then fixed by the fastening screws 215, so that the device can be adjusted according to the diameter of the wire, so that the center points of the wires transported by the tape are at the same height;

[0062] The first electric cylinder 106 is used to drive the first rack 107 to move. The movement of the first rack 107 drives the first gear 105 and the first central axis 104 at the center thereof to rotate. The rotation of the first central axis 104 drives the first turntable 103 to rotate. The rotation of the first turntable 103 drives the first cylinder 111 thereon to make a circular rotation. The rotation of the first cylinder 111 drives the deflection bracket 203 on its outer ring to deflect around the deflection axis 204 and slide along the arc rod 202. Then, the tape roll and the empty tube are placed on two threaded columns 212 respectively, and the adhesive side of the tape is passed through several rollers 217 with the sticky side facing upwards. Then, the tape roll and the empty tube are fixed by the threaded sleeve 213. Then, the first electric cylinder 106 is used to reset the deflection bracket 203.

[0063] The wire and material to be welded are transported to between the two clamps 311 of the material receiving mechanism 3 by the first feeding device 109 and the second feeding device 110, and then the third electric cylinder 402 is used to drive the moving block 403 to move, and the movement of the moving block 403 drives the connecting arm 405 hinged to the third hinge seat 404 thereon to deflect, and the scissors 406 hingedly connected to the other end of the connecting arm 405 deflect around the bottom end of the fixed bracket 401 accordingly, and the welding wire is cut by the deflection of the two scissors 406;

[0064] Then, the second electric cylinder 307 is used to drive the second rack 308 to move, and the movement of the second rack 308 drives the second gear 304 and the second central axis 303 at the center thereof to rotate, and the rotation of the second central axis 303 drives the second turntable 305 to rotate, and the rotation of the second turntable 305 drives the second cylinder 306 to rotate, and the mobile bracket 310 on the outer ring of the second cylinder 306 moves along the slide bar 309 accordingly, so that the clamps 311 on the two mobile brackets 310 move toward each other, and the silk threads and logistics on the clamps 311 of the two material receiving mechanisms 3 then fall from the clamps 311 and adhere to the tape below them;

[0065] The first rotating shaft 205 is driven to rotate by a motor, and the rotation of the first rotating shaft 205 drives another first rotating shaft 205 whose end is connected by a first hinge seat 207, a second hinge seat 210, a sleeve 208 and a sleeve shaft 209 to rotate accordingly. Then, the first rotating shaft 205 and the second rotating shaft 206 are connected by a synchronous belt and a synchronous wheel to drive the second rotating shaft 206 to rotate accordingly. The rotation of the second rotating shaft 206 drives the threaded column 212 at its end to rotate, thereby moving the tape to transport the wire and material thereon, and when the wire and material are transported to the welding mechanism 5, the ends of the wire and material can contact each other;

[0066] The servo motor 505 is used to drive the third rotating shaft 504 to rotate, and the rotation of the third rotating shaft 504 drives the third gear 506 at its end to rotate. The two third gears 506 are meshed with each other to make the two third gears 506 rotate towards each other, and the third cylinder 507 on the third gear 506 rotates in a circle accordingly, thereby driving the moving ring 509 of its outer ring to move, so that the two moving frames 508 are close to each other. When the moving frame 508 moves, the roller 511 on the fixed rod 510 on it moves along the guide rail 502, so that the clamping plates 515 close to each other can clamp the wire and the material. As the moving frame 508 continues to move, the spring 513 is in a compressed state until the welding device 516 and the welding base 517 are at a suitable welding distance from the wire and the material, and then the welding device 516 is used for welding;

[0067] After welding is completed, the welding mechanism 5 is reset, and then the tape continues to drive the welded finished product to move, and the welded position can be inspected to check whether the welded position is firm, and finally the welded finished product on the tape is taken away by the material taking device.

[0068] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
