Technical Field

[0001] The utility model belongs to the technical field of tin wire processing, in particular to a soldering machine for preheating tin wire. Background Art

[0002] In the production process of electrical products, a series of parts need to be fixed by soldering, such as capacitors and resistors on circuit boards. In order to improve production efficiency, fully automatic or semi-automatic soldering machines are usually used for soldering. The core part of the soldering machine is the machine head and welding system. The welding system mainly includes the tin feeding mechanism and temperature control, heating element, soldering head, and tin wire spitting gun. The tin wire is drawn from the tin wire roll through the tin wire spitting gun and spitted to the gun head through the conveyor roller.

[0003] At present, when a soldering machine is in use, the solder wire is generally sent to a position close to the soldering iron tip through a tin feeding device, and the solder wire is melted by the soldering iron tip. Normally, the temperature of the solder wire itself is generally the same as the external ambient temperature. When the external ambient temperature is low, the temperature of the solder wire will decrease, and the temperature of the solder wire itself is low. The soldering iron tip needs a longer time to melt the solder wire. Moreover, the low-temperature solder wire suddenly heats up. Due to excessive thermal shock, part of the tin will sublimate, affecting the health of the operator.

[0004] Therefore, based on the above problems, we designed a soldering machine for preheating the tin wire. Utility Model Content

[0034] Among them, each gear 1 41 is driven by a servo motor externally arranged on both sides of the preheating channel 2. The main shaft of the servo motor is connected to the gear 1 41. Each servo motor drives the gear 1 41 and the gear 2 42 to rotate separately, thereby driving the two sets of guide wheels 4 to rotate and guide the tin wire.

[0035] like Figures 1 to 3 As shown, in this embodiment, an adjusting rod 5 is further provided on the base 11, an adjusting slot 51 is provided in the middle of the adjusting rod 5, an adjusting screw 52 is penetrated through the adjusting rod 5, a slider 53 is provided on the back of the preheating channel 2, the slider 53 is slidably provided in the adjusting slot 51, and is threadedly sleeved on the adjusting screw 52, ​​and the height of the preheating channel 2 is adjusted by adjusting the adjusting screw 52 to meet different soldering requirements.
