[0144] The working principle of the double parallel elbow soldering machine of the present invention is as follows:

[0145] Wire from Figure 4 The wire 100 is manually clamped on the wire clamping fixture 435. When the wire clamping fixture 435 runs to the left side of the chain transmission group 43, it will automatically open. After manual threading, the chain transmission group 43 rotates one station, the pressure cover 4351 on the wire clamping fixture 435 is pressed tightly by the pressure strip, and the pressure glue 4352 presses the wire 100.

[0146] The wire 100 runs to the line-fixing part on the cutting and stripping line-fixing group 42, the line-fixing cylinder 421 and the line-dividing cylinder 422 on the cutting and stripping line-fixing group 42 will be pressed down synchronously, the line-fixing cylinder 421 drives the line-fixing claw 427 to press down, corrects the wire into a straight shape and brings the positive and negative wires together, after the wire 100 is fixed, the line-fixing cylinder 421 rises, and the fixed wire 100 is sent to the line-correcting part.

[0147] The line setting cylinder 421 and the line dividing cylinder 422 will be pressed down synchronously, and the line dividing cylinder 422 drives the line dividing block base 423 on it to be pressed down. The two V-shaped structured line correcting claws on the line dividing block base 423 face downward, and the line dividing block 424 on the line correcting part separates the wires and corrects the wires at the same time. Fig.11 When the wire 100 runs to the wire-correcting part, the wire-correcting part is provided with two blocks, wherein the guide groove on one of the blocks pre-presses one of the negative core wires to 90 degrees, and the guide groove on the other block pre-presses the other positive core wire to 10 degrees. Fig.12 The structure of the wire after bending is shown].

[0148] Working principle of the pulling, cutting and stripping group 41: When the chain transmission group 43 sends the wire to this work station, the pulling, cutting and stripping group 42 presses the wire and then the upper and lower cylinders move. The wire correction V-shaped plate of the wire dividing station group corrects the wire. The second wire dividing cylinder 422 cuts the wire with a blade, and the rear blade of the cutting and stripping station cuts the wire, and the front blade cuts the rubber. The horizontal cylinder is pulled back, and the blade of the wire dividing station group cuts the wire to play a role in dividing the wire, and the front blade of the cutting and stripping station drives the wire skin to strip the wire skin. Finally, all cylinders are reset and the blowing block blows away the wire skin on the blade to complete the pulling, cutting and stripping action.

[0149] Working principle of solder group 44: Initial state: the lifting cylinder 444 on the solder group 44 is retracted upward, and the left and right solder cylinders 448 are retracted. When the wire clamping fixture 435 delivers the wire into place, the solder line-fixing group 45 completes the line fixing, and the upper folding line group folds the wire upward to 90 degrees. After the DC copper nail 200 is delivered into place through the direct vibration mechanism, the two groups of lifting cylinders 444 move downward synchronously, driving the left and right solder cylinders 448 to drop to the solder height; the tin feeders 441 at both ends deliver a small section of tin wire; the left and right solder cylinders 448 push out, squeeze the tin wire, stay for 1s, and solder the copper wire on the core wire to the DC copper nail 200; the two groups of lifting cylinders 444 are retracted, the left and right solder cylinders 448 are retracted, the solder line-fixing group 45 and the upper folding line group cylinders are retracted, and a line fixing soldering is completed.

[0150] After soldering is completed, the chain transmission group 43 rotates one station, the cylinder on the lower pressing group presses down, the wire fixing fork on it fixes the wire and presses the wire straight. The wire squeezing group holds tightly, and the wire squeezing clamp on it squeezes the core wire together.

[0151] Finally, the chain transmission group 43 rotates one station, the wire clamping fixture 435 leaves the pressure bar, the pressure cover on it is loosened, and the welded wire is manually taken out. Fig.21 Schematic diagram of the wire structure after welding].
