First embodiment

Referring to fig. 1, a schematic structural diagram of a tin feeding mechanism in a first embodiment of the present invention is shown. The tin feeding mechanism in the embodiment includes a conveying pipe (including a first pipe 11 and a second pipe 12), a switch 2, a contact portion 3, a fixed block 4, a conveying roller (including a driving roller 51 and a driven roller 52), a driving portion 6, a guide pipe 7, a protection pipe 8 and a frame 9.

The tin wire 0 passes through the guide tube 7, enters between the driving roller 51 and the driven roller 52, and then passes through the first tube 51, the second tube 52 and the protection tube 8 in sequence. In this embodiment, the transport direction of the solder wire 0 is from top to bottom. First pipe 11 and second pipe 12 all pass fixed block 4, and second pipe 12, switch 2 all with fixed block 4 fixed connection. The fixed block 4, the driving part 6, the guide pipe 7 and other parts are all fixed on the frame 9.

The driving part 6 is fixedly connected with the driving roller 51, and the driving roller 51 is driven by the driving part 6 to rotate. In this embodiment, the driving unit 6 is a motor. The driven roller 52 is pressed toward the drive roller 51. When the driving roller 51 rotates counterclockwise, the driven roller 52 is driven to rotate clockwise, and the tin wire 0 between the driving roller and the driven roller is pulled to move downwards, so that the tin wire 0 is conveyed. Preferably, the driven roller 52 has a plurality of serrations on its surface to increase friction with the solder wire 0 and prevent the solder wire 0 from slipping.

Referring to fig. 2, a side view of a part of the structure of the tin feeding mechanism according to the first embodiment of the present invention is shown, in which the fixing block and the like are omitted. The tin wire 0 passes through the first tube 11 and the second tube 12 after passing through the driving roller 51 and the driven roller 52. The contact portion 3 is located between the first tube 11 and the switch 2, and the contact portion 3 has a certain elasticity. The switch 2 is provided with a trigger block 21. The first end 31 of the contact part 3 is fixedly connected to the switch 2. The surface of the first pipe 11 is provided with a pressing portion 111, and the second end 32 of the contact portion 3 is located at the pressing portion 111. In the present embodiment, the pressing portion 111 is provided as a groove on the surface of the first pipe 11.

When the solder wire 0 is normally carried, a gap is formed between the second end 32 of the contact portion 3 and the pressing portion 111, and a gap is also formed between the first end 31 of the contact portion 3 and the trigger block 21. The elastic member 112 is sleeved outside the bottom end of the first tube 11, and the bottom end of the first tube 11 extends into the second tube 12. The elastic member 112 is fixedly connected to both the first tube 11 and the second tube 12. In this embodiment, the elastic member 112 is a spring.

The protection tube 8 is located the below of second pipe 12, and the protection tube 8 can lead to tin line 0, and can protect tin line 0, prevents that tin line 0 from appearing buckling or damaging because of external collision or other factors in transportation process.

If the apparatus is out of order, the solder wire 0 cannot be consumed after reaching the soldering point, and the drive roller 51 and the driven roller 52 are still rotating, and the solder wire 0 is still continuously conveyed downward. Because the outer cover of tin wire 0 is equipped with protection tube 8, first pipe 11 and second pipe 12, it all can restrict the position of tin wire 0, makes it unable the bending, pile up and scatter outwards, consequently, tin wire 0 will produce at first in the top department of first pipe 11 and pile up. After the solder wire 0 is accumulated to a certain degree, the first tube 11 will be pressed to move downward, and when the solder wire is moved to a certain position, the edge 113 of the pressing portion 111 will be tightly abutted against the second end 32 of the contact portion 3, and will jack up the second end 32 of the contact portion 3 toward the switch 2. The first end 31 of the contact portion 3 elastically rotates in the direction of the switch 2 and contacts the trigger block 21 to trigger the switch 2. The switch 2 will stop the rotation of the drive roll 51, stop the transportation of the tin wire 0 and send an alarm to remind the operator to overhaul the equipment. During the above process, the elastic member 112 is in a compressed state. After the equipment failure is resolved, under the resilience of the elastic member 112, the first tube 11 will move upward to return and be separated from the second end 32 of the contact portion 3, and the contact portion 3 also returns, and the first end 31 of the contact portion 3 is separated from the trigger block 21.

In addition, the embodiment also provides a welding machine which comprises the tin feeding mechanism.
