TECHNICAL FIELD
[0001] The utility model relates to a tin soldering device, in particular to a tin soldering device for soldering tool thermistor and wire. BACKGROUND
[0002] Electronic devices (such as thermistor) need to be soldered on the wire before use. Usually, the pins of thermistor and wire are soldered together by tin soldering. When tin soldering, solder tin needs to be sent to two pin positions respectively, so that the soldering efficiency is low. SUMMARY

[0013] The structure of the tin soldering device and other aspects of the utility model are further described in detail below through specific embodiments and with reference to the accompanying drawings.
[0014] As Figures 1 to 3 shown, the tin soldering device of the utility model comprises an upper soldering tool 1, a lower soldering tool 2, a heating device 3 and a tin feeding machine 4. The upper soldering tool 1 can move to approach or move away from the lower soldering tool 2, and the lower soldering tool 2 remains stationary. The heating device 3 is used to heat the lower soldering tool 2 to melt the end of the tin wire delivered to the lower soldering tool 2. The tin feeding machine 4 is used to deliver the tin wire to the welding position.
[0015] In a specific embodiment, the tin soldering device of the utility model comprises a horizontal sliding block 5 and a vertical sliding block 6. The horizontal sliding block 5 is slidably mounted on a fixed frame 7, and the horizontal sliding block 5 can move horizontally along the fixed frame 7 through a sliding rail and a sliding groove. The vertical sliding block 6 is slidably mounted on the horizontal sliding block 5, and the vertical sliding block 6 moves up and down along the horizontal sliding block 5 through a sliding rail and a sliding groove provided on the vertical sliding block 6 and the horizontal sliding block 5.
[0016] The upper soldering tool 1 is mounted on the vertical sliding block 6 and can move with the vertical sliding block 6 to approach or move away from the lower soldering tool 2. The tin feeding machine 4 is mounted on the vertical sliding block 6. The tin feeding machine 4 belongs to existing equipment, and mature products can be purchased on the market, such as the tin feeding machine produced by Shenzhen Zhongbangbao Technology Co., Ltd.
[0017] As Figure 4 shown, the lower soldering tool 2 has a wire separation protrusion 21, and during welding, the two pins of the thermistor are placed on both sides of the wire separation protrusion 21. The wire separation protrusion 21 can avoid the solder flowing during welding to cause the two pins to be welded together. Correspondingly, the upper soldering tool 1 is provided with a groove 11, and the groove 11 is used to accommodate the wire separation protrusion 21 when the upper soldering tool 1 and the lower soldering tool 2 are in contact.
[0018] In a preferred embodiment, the lower welding fixture 2 has a positioning plate 22 with two positioning notches 221, which are located on both sides of the branching protrusion 21. The two leads or wires of the thermistor are placed within the positioning notches 221 to prevent the object being welded from shifting.
[0019] In a specific embodiment, the heating device 3 includes a heating block 31 and a heating rod 32 located within the heating block 31. The heating block 31 at least partially surrounds the lower welding fixture 2, thereby transferring heat to the lower welding fixture 2. The heating rod 32 generates heat when energized.
[0020] When the solder feeder 4 feeds the solder wire, the solder wire is at a certain angle to the horizontal direction, so that only the end of the solder wire can contact the dividing protrusion 21 or the object to be soldered. When the solder feeder 4 feeds the solder wire, the projection of the solder wire on the horizontal plane is perpendicular to the projection of the dividing protrusion 21 on the horizontal plane.
[0021] When this soldering device is in operation, the thermistor and wire are first placed in the positioning groove 221 of the lower soldering fixture 2, with the two leads of the thermistor located on both sides of the dividing protrusion 21. The horizontal slider 5 moves horizontally until the upper soldering fixture 1 and the lower soldering fixture 2 are in the same vertical position. The vertical slider 6 moves the upper soldering fixture 1 towards the lower soldering fixture 2 until the upper soldering fixture 1 and the lower soldering fixture 2 clamp the thermistor and wire in the middle. The solder feeder 4 delivers the end of the solder wire from the side to above the thermistor leads and into contact with the dividing protrusion 21. The end of the solder wire is heated by the heating block 31 until it melts. The melted solder is distributed on both sides of the dividing protrusion 21 and bonds the thermistor leads and wire together.
[0022] Compared to existing technologies that feed solder wire along the direction of the thermistor leads, this soldering device feeds the solder wire perpendicular to the thermistor leads. The ends of the solder wire are overlapped onto both leads of the thermistor in one pass, achieving soldering of both leads in a single operation, resulting in high soldering efficiency.
[0023] The above embodiments are only used to illustrate the concept and scope of this utility model and are not intended to limit the protection scope of this utility model. Modifications, equivalent substitutions, and other improvements to the above embodiments that are obvious to those skilled in the art are also within the concept of this utility model. The protection scope and concept of this utility model are specifically defined by the claims.
