DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides Figure 1 - Figure 7 The chip inductor winding welding mechanism shown includes an operating table 1 and a chip inductor 2. A welding device 8 for welding the chip inductor 2 is also provided on the operating table 1. A welding gun is installed at the bottom of the welding device 8. The chip inductor 2 is also called a surface mount inductor, which is a new generation of leadless or short-lead microelectronic components suitable for surface mount technology (SMT). An infrared position sensor is also integrated on the welding device 8. This sensor can assist the welding gun to weld the chip inductor 2 more accurately, thereby improving the accuracy and efficiency of welding.

[0024] The surface of the operating table 1 is provided with a welding base 3, and the surface of the welding base 3 is provided with a plurality of positioning blocks 7 which are arranged at equal distances, so as to facilitate the installation of the circuit board 4 and to limit the circuit board 4 so that it will not deviate during the welding process. The surface of the welding base 3 is slidably provided with the circuit board 4, and the welding base 3 is used to place the circuit board 4;

[0025] An auxiliary welding component 5 for welding the chip inductor 2 is provided on the welding base 3, which is mainly used for wrapping protection when welding the chip inductor 2 on the circuit board 4, ensuring that during the welding process, only the pin part of the chip inductor 2 is exposed for welding, while the rest of the chip inductor 2 is fully protected, reducing the direct impact of the thermal stress generated by the welding gun on the inductor body, thereby enhancing the welding accuracy and the stability of the chip inductor 2;

[0026] The auxiliary welding assembly 5 includes a tray 501, which is slidably arranged on the surface of the welding base 3. The inner wall of the tray 501 has a plurality of support bars 502 that are equidistantly arranged. A protective cover 503 is arranged at the bottom of the support bar 502. The protective cover 503 is made of a high heat-resistant material to ensure that a good protective function can be maintained even in a high temperature environment.

[0027] A spring 504 is provided on the inner wall of the protective cover 503, and a sliding sheet 505 is provided at one end of the spring 504. The sliding sheet 505 is slidably connected to the inner wall of the protective cover 503. A welding groove 506 is symmetrically provided at one end of the protective cover 503 away from the support bar 502. A plurality of equally spaced limiting holes 507 are provided on the surface of the welding base 3. A plurality of equally spaced limiting rods 508 are provided at the bottom of the tray 501, and the limiting rods 508 are plugged into the limiting holes 507.

[0028] When the chip inductor 2 needs to be welded, the chip inductor 2 is first mounted on the circuit board 4, and then the circuit board 4 is placed on the welding base 3, and then the limiting rod 508 of the tray 501 is aligned with the limiting hole 507 of the welding base 3, and the limiting rod 508 is inserted into the limiting hole 507. At this time, the protective cover 503 on the tray 501 wraps the chip inductor 2, and the sliding sheet 505 is close to the surface of the chip inductor 2. At this time, the spring 504 is compressed, and only the pins on both sides of the chip inductor 2 are leaked out, so as to limit the installation of the chip inductor 2, and then the welding equipment 8 is driven to weld the pins of the chip inductor 2, and the setting of the protective cover 503 only allows the pins of the chip inductor 2 to leak out, thereby reducing the influence of the thermal stress generated by the welding gun when welding the pins on the chip inductor 2 itself, and can also effectively prevent the welding gun from deviating and directly contacting the chip inductor 2, reduce the direct contact between the welding gun and the body of the chip inductor 2, and provide additional safety protection for the inductor.

[0029] The surface of the operating table 1 is provided with a cooling component 6 for dissipating heat after the chip inductor 2 is welded. The cooling component 6 mainly utilizes wind power to dissipate heat at the welding position of the chip inductor 2 after welding, thereby minimizing the influence of thermal stress generated during the pin welding process on the chip inductor 2 and ensuring the stability of the chip inductor 2 during the welding process.

[0030] The cooling assembly 6 includes a fan 601, which is arranged on the surface of the operating table 1. A dustproof net is arranged at the air inlet end of the fan 601, which not only ensures that the fan 601 can smoothly inhale air, but also effectively blocks impurities in the wind, thereby extending the service life of the fan 601;

[0031] The air outlet end of the fan 601 is provided with an inclined tube 602, and the surface of the operating table 1 is provided with a hollow tube 603. The hollow tube 603 has a plurality of air outlets 604 arranged at equal distances on one side close to the welding base 3. The positions of the air outlets 604 correspond to the support bars 502, thereby ensuring that the wind can be accurately blown to the welding part that needs heat dissipation, which improves the heat dissipation effect as a whole and ensures the convenience of operation.

[0032] The end of the air outlet 604 close to the welding base 3 is tilted so that the wind can form a greater wind pressure when blowing out. At the same time, the design of the inner wall of the air outlet 604 gradually decreases from large to small, so that the flow rate of the wind gradually increases, the wind force is greater, and the wind can be blown farther. Such a design ensures that even the chip inductor 2 farthest from the air outlet 604 can be blown by the wind, thereby effectively improving the heat dissipation effect;

[0033] By driving the fan 601 to rotate, wind is blown into the inclined tube 602 and into the hollow tube 603, and is blown out through the air outlet. When the blown wind contacts the welding part of the chip inductor 2, the welding part of the chip inductor 2 can be cooled. The setting of the protective cover 503 can prevent the blown hot air from directly contacting the chip inductor 2 body.
