Tin structure

This creation is about a tin-out structure, especially that it can restrict the movement of the tin wire so that the tin wire does not produce sliding when it is output, and the precision of the wire length is improved.

Pressing; the tin machine is a device for automatically feeding tin during welding in the manufacturing process of electronic products. At present, the automatic tin-spinning machine usually rotates and holds the tin wire by the gear structure, and the tin wire is guided out. However, at least the following deletions actually occur: Because the wire diameter of the tin wire is very small, only the gear is used to hold the wire. The wire is only driven by the friction force. Because the gear does not penetrate into the wire, the friction between the wire and the gear is insufficient, and the wire is slipped. The problem of inconvenient conveying of the wire or the inaccurate distance of the conveying length is that the amount of tin in the welding is not accurate enough to form a problem of poor soldering quality and good yield.

Therefore, the current structure of the tin machine has not been ideal, and it is necessary to improve it.

Therefore, the creator is constantly researching the concept of improvement and innovation based on products, and is based on the practical experience of the product development for many years, as well as actively researching and thinking, and through numerous practical design experiments, the creation of this creation.

The purpose of this creation is to provide a blade piercing with a tooth cutter by a tooth cutter wheel. The tin wire can restrict the movement of the tin wire so that the tin wire output does not cause sliding phenomenon, and the tin length distance is accurate, thereby providing a precise structure of the tin amount during welding.

In order to achieve the above purpose, the present invention comprises a tin module, a tooth cutter wheel and a motor, wherein the tin module comprises a first conveying tin tube, a second conveying tin tube and a tin wire conveying rotating body. The first conveying tin tube and the second conveying tin tube are arranged up and down and define a working space at the corresponding end, the tin wire conveying rotating body is movable to install a tin wire and rotate the The tin wire is conveyed through the first conveying tin pipe, the working space and the second conveying tin pipe; the tooth cutter wheel is disposed on one side of the working space, the tooth cutter wheel has a tooth cutter, and the tooth cutter has a plurality of blades The motor is coupled to the tooth cutter wheel for driving the gear wheel; and the driven wheel device includes a driven wheel, the driven wheel is a rotatable wheel body, and the driven wheel is, for example, an idler wheel. The driven wheel device is disposed on the other side of the working space, and the driven wheel is disposed on the tooth cutter wheel side.

When the tin wire is transported to the working space, the tin wire is clamped between the driven wheel and the toothed wheel, and when the motor drives the toothed wheel to simultaneously drive the driven wheel, the blade of the toothed knife is rotated by the toothed wheel Puncture the tin wire, thereby restricting the movement of the tin wire so that it does not cause sliding phenomenon, and the precision of the wire feeding length distance is increased, so as to provide accurate soldering amount, and the conventional skill can be overcome. The wire is conveyed, and the friction between the wire and the gear is insufficient due to the lack of penetration into the tin wire, which causes the wire to slip, which causes the difficulty of conveying the wire or the inaccurate distance of the conveyance cannot provide the correct amount of solder.

The advantageous effect of the novel is to improve the precision of the distance between the lengths of the conveying wires, and to make the amount of tin in the welding precise, to gain the quality of the soldering and to improve the yield.
