[0033] During assembly of the present invention, the mounting base 2 is fixed on the frame 1, the turntable 3 is rotatably mounted in the mounting base 2, and the turntable 3 is driven to rotate by a motor. The first shaft seat 6 and the second shaft seat 26 are fixedly mounted on the rear side of the turntable 3, the first take-up shaft 12 is rotatably mounted in the first shaft seat 6, and the second take-up shaft 22 is rotatably mounted in the second shaft seat 26. The first take-up shaft 12 and the second take-up shaft 22 are respectively driven to rotate by separate motors, the first fixed disk 9 and the second fixed disk 25 are respectively mounted on the first take-up shaft 12 and the second take-up shaft 22 and rotate with the first take-up shaft 12 and the second take-up shaft 22, and at the same time, the first wire clamping spring 15 and the second wire clamping spring 20 are respectively mounted on the outer cylindrical conical surface of the first fixed disk 9 and the outer cylindrical conical surface of the second fixed disk 25.

[0034] The first blade 13 and the second blade 18 are fixed to the first blade support 5 and the second blade support 19 through the first clamping plate 14 and the second clamping plate 17 respectively, and then fixed as a whole to the turntable 3. The first wire stop rod 16 and the second wire stop rod 24 are arranged above the first wire take-up spool 10 and the second wire take-up spool 23 and fixed to the turntable 3.

[0035] The cylinder 4.1 is fixed to the cylinder base 4.2, and a Y-type joint 4.4 is fixedly installed at the end of the piston rod of the cylinder 4.1. The cutting rod 4.5 is connected to the Y-type joint 4.4 through a rotating pin 4.7, and is connected to the T-type support 4.3 through a connecting plate 4.6 and a rotating pin 4.7 to form a connecting rod mechanism. The T-type support 4.3 is fixed to the cylinder 4.1. When the piston rod of the cylinder 4.1 is extended, the cutting rod 4.5 is lifted, and when the piston rod of the cylinder 4.1 is retracted, the cutting rod 4.5 is pressed down. A counterweight 4.8 is fixed on the cutting rod 4.5 away from the Y-type joint 4.4 to increase the cutting force. The cutting cylinder device 4 is fixed to the frame 1 as a whole.

[0036] When starting the machine for the first time, first put the first take-up spool 10 and the second take-up spool 23 on the first take-up shaft 12 and the second take-up shaft 22 respectively and put them close to the first fixed disk 9 and the second fixed disk 25, and then use the first locking nut 11 and the second locking nut 21 to lock the first take-up spool 10 and the second take-up spool 23. At this time, the cylinder 4.1 in the cutting cylinder device 4 is in an extended state, and the cutting rod 4.5 is lifted. Then manually pass the tinned solder strip 8 around the wire arrangement guide wheel 7, clamp it in the first wire clamping spring 15 and wind it onto the first take-up spool 10. The reciprocating motion of the wire arrangement guide wheel 7 can evenly arrange the tinned solder strip 8 on the first take-up spool 10. The first take-up shaft 12 drives the first fixed disk 9 and the first take-up spool 10 to rotate counterclockwise. At this time, the second take-up shaft 22 stops rotating. Figure 1 After running for a period of time, when the first take-up spool 10 is nearly full, the turntable 3 rotates 180° counterclockwise. Figure 2 As shown, at this time, the first take-up spool 10 is located at the original position of the second take-up spool 23, and the tinned solder strip 8 is located above the second take-up spool 23. The second take-up shaft 22 drives the second fixed disk 25 and the second take-up spool 23 to rotate counterclockwise, and the first take-up shaft 12 and the second take-up shaft 22 rotate simultaneously. When the first take-up spool 10 is full, as shown in FIG. Figure 3 As shown, the piston rod of the cylinder 4.1 in the cutting cylinder device 4 is retracted, and the cutting rod 4.5 is pressed down to hit the tin-coated solder strip 8, and the tin-coated solder strip 8 is clamped by the second wire clamping spring 20 on the second fixed disk 25 rotating at a high speed. At the same time, the tin-coated solder strip 8 contacts the second blade 18 and is cut. As the wire arrangement guide wheel 7 reciprocates back and forth, the tin-coated solder strip 8 can be evenly arranged on the second wire take-up I-shaped wheel 23, as shown in FIG. Figure 4 As shown, the first take-up shaft 12 stops rotating at this time. Then the first take-up spool 10 with a full reel is manually removed, and the first take-up spool 10 with an empty reel is installed. When the second take-up spool 23 is close to a full reel, the turntable 3 rotates 180° counterclockwise, that is, the above steps are repeated to realize the cutting of the tinned solder strip 8 and the replacement of the spool without stopping the machine.

[0037] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
