For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0034] The following is combined with Figures 1 to 7 The technical solution of the utility model is further illustrated by specific implementation methods.

[0035] like Figure 1 and Figure 5-7 As shown, an automatic soldering machine includes a processing table 1, a conveying mechanism 2, a flux tank 3, a soldering furnace 4, a scraping mechanism 5, a walking mechanism 6, a carrier 7 and a housing 8. The conveying mechanism 2, the flux tank 3, the soldering furnace 4 and the scraping mechanism 5 are arranged in sequence on the processing table 1. The conveying mechanism 2 is used to transport the carrier 7 to the processing area. The carrier 7 is used to load the coil to be soldered. The flux tank 3 is used to store the flux. The soldering furnace 4 is used to store the solder liquid. The scraping mechanism 5 is used to scrape off the solder liquid oxidized on the surface. The processing table 1 is wrapped as a whole by the housing 8. The top of the housing 8 is provided with an air guide component 81;

[0036] The walking mechanism 6 is arranged above the processing table 1, and the walking mechanism 6 includes a slide rail, a power source and a claw member, and the claw member includes a claw arm 611 and a claw groove 612. There are two claw members, and the two claw members are arranged opposite to each other; the power source drives the claw member to slide on the slide rail and drives the claw groove 612 to rotate; the claw groove 612 is detachably installed at the bottom of the claw arm 611, and a notch is provided on one side wall of the claw groove 612, and the groove wall of the notch is provided with an inclined surface 6121, and the inclined surface 6121 is inclined inwardly, and the claw groove 612 is hooked along the inclined surface 6121 to the raised portion 71 of the carrier 7; the groove width of the claw groove 612 is greater than the width of the raised portion 71.

[0037] Specifically, the scraping mechanism 5 scrapes off the oxidized solder liquid on the surface of the solder furnace 4, and the air guide component 81 (refer to Figure 7 ) to discharge the harmful gases generated during the soldering process, the conveying mechanism 2 conveys the carrier 7 to the processing area 212, the walking mechanism 6 moves to the top of the processing area, and the two claw grooves 612 simultaneously hook the protrusion 71 of the carrier, and then the walking mechanism 6 drives the carrier 7 to move, so that the coil to be soldered is completely dipped into the soldering agent and solder liquid in the flux tank 3 and the soldering furnace 4, and finally, the walking mechanism 6 moves the carrier 7 loaded with the soldered coil to the receiving area 222 of the conveying mechanism 2 to complete the soldering process. When the claw member completes the hook, as shown in FIG. Figure 2 As shown, the groove width of the claw groove 612 is greater than the width of the protrusion 71, so that a gap is left between the inner wall of the claw groove 612 and the protrusion 71, ensuring that the protrusion 71 can completely fall into the groove of the claw groove 612, and the gap between the inner wide wall of the claw groove 612 and the edge of the protrusion 71 is 1-2 mm, and the gap between the inner long wall of the claw groove 612 and the edge of the protrusion 71 is 0.5-1 mm. The connection between the claw groove 612 and the protrusion 71 is more flexible, because there is no need to accurately align the inner wall of the claw groove 612 with the edge of the protrusion 71, and loading and unloading are easier.

[0038] Specifically, the number of the air guide components 81 is at least two, which guide and discharge the harmful gases generated during the soldering process to avoid inhaling harmful gases and causing harm to the body. At the same time, it can accelerate the solidification of the molten tin of the pins of the soldering coil. The walking mechanism 6 includes a slide rail, a power source, and a claw member. The claw member includes a claw arm 611 and a claw groove 612. The number of the claw members is two, and the two claw members are arranged opposite to each other; the power source drives the claw member to slide on the slide rail and drives the claw groove 612 to rotate; a transmission chain is provided inside the claw arm 611, and a transmission shaft is provided at the corner of the claw arm 611. The transmission chain connects the power source, the transmission shaft and the claw groove 612. The power source drives the transmission shaft to rotate through the transmission chain, and then drives the claw groove 612 to rotate. The power source can be a driving device such as a motor or a cylinder. The claw groove 612 is detachably mounted on the bottom of the claw arm 611 by drilling a hole with a screw, which is convenient for replacing the claw groove 612 to meet the needs of different carriers 7. A notch is provided on one side wall of the claw groove 612, and an inclined surface 6121 is provided on the groove wall at the notch. The two inclined surfaces 6121 are inclined inwardly, and the claw groove 612 hooks the raised portion 71 of the carrier 7 along the inclined surface 6121 to prevent the raised portion 71 from getting stuck and being unable to enter the claw groove 612. The carrier 7 falls into the claw groove 612, and the bottom surface of the raised portion 71 is connected to the bottom surface of the claw groove 612. The claw member drives the solder coil in the carrier 7 to move stably to complete the soldering operation.

[0039] In summary, the utility model sets the inclined surface 6121 so that the raised portion 71 of the carrier is hooked with the claw groove 612 of the claw member, thereby preventing the raised portion 71 from getting stuck and unable to enter the claw groove 612. At the same time, the groove width of the claw groove 612 is greater than the width of the raised portion 71, so that the raised portion 71 can completely fall into the groove of the claw groove 612, and the raised portions 71 at both ends of the carrier 7 remain parallel in the claw groove 612. The coil to be soldered loaded on the carrier 7 can maintain the consistency of the solder height when dipping in the flux liquid and the solder agent, thereby reducing the production loss rate and improving the stability of the solder.

[0040] Preferably, if Figure 3 and Figure 4 As shown, the height of the inner side wall at the notch is H1, the height of the inclined surface 6121 at the notch is H2, the height of the protrusion 71 is H3, and H1-H2>H3.

[0041] Specifically, the height of the protrusion 71 should be smaller than the height of the inner wall at the notch minus the height of the inclined surface 6121 at the notch. The protrusion 71 is placed inside the claw groove 612, so that when the power source drives the claw groove 612 to rotate, the inner wall surface at the notch of the claw groove 612 stably supports the protrusion 71. The structure is simple and the operation is smooth and reliable.

[0046] Specifically, the flux liquid supply box 33 replenishes the flux liquid to the second flux tank 32 through a liquid pump. Since the height of the second flux tank 32 is higher than that of the first flux tank 31, the second flux tank 32 overflows into the first flux tank 31 after being filled, and the flux liquid then returns to the flux liquid supply box 33 through the liquid outlet of the first flux tank 31, so that the height of the flux liquid in the second flux tank 32 remains unchanged, and the walking mechanism 6 takes the height of the flux liquid according to the set parameters.
