Description

Technical Field

[0001] The present application relates to the technical field of hot air welding, and in particular to a hot air table for processing a stepper motor driver. Background Art

[0002] The hot air table uses the principle of light wind heating to remove tin, which can quickly and cleanly disassemble components of various packaging forms. The types of hot air tables on the market are mainly straight-air hot air tables and cyclonic hot air tables. Both are composed of air guns and host machines. The main difference between the two is the air supply method. The former is to install an air pump on the host machine and introduce the air into the air gun through the air duct, while the latter is to install a fan directly on the air gun; both air guns are equipped with nozzles, heating components and temperature detection devices. The nozzle is mounted on the heating component, and the temperature measurement device is installed at one end of the heating component. The heating component heats the air, and the air pump or fan discharges the hot air from the nozzle.

[0003] In the prior art, the nozzle size of the hot air station is uniform during welding and removal. When welding a smaller weld, it is easy to melt the nearby welded points, resulting in loose welding. If the nozzle is too small when welding a larger position, it will increase the welding time and affect the welding efficiency. Utility Model Content

[0008] By adopting the above technical solution, in order to avoid the position displacement of the air outlet nozzle during operation, the adjusting nut is abutted against the end of the rotating tube to apply friction to the rotating tube.

[0009] Preferably, a plurality of layers of adjusting pads are adhered to one end of the air outlet nozzle close to the air outlet pipe.

[0010] By adopting the above technical solution and using different numbers of adjustment pads, the gap between the air outlet nozzle and the air outlet pipe can be reduced, thereby reducing the leakage of hot air.

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses a hot air table for processing a stepper motor driver, referring to Figure 1-3 , including a main unit 1 and a hot air gun 2 connected to the main unit 1, the hot air gun 2 including a gun body 21 and an air outlet pipe 22, a nozzle replacement mechanism 3 is provided on the gun body 21, the nozzle replacement mechanism 3 includes a rotating sleeve 31, a center rod 32 and a rotating tube 33, one end of the center rod 32 is fixed on the gun body 21, and the center rod 32 is arranged parallel to the air outlet pipe 22, the rotating tube 33 is rotatably connected to the center rod 32, a nozzle assembly is installed at the outlet end of the rotating tube 33 near the air outlet pipe 22, the nozzle assembly includes a plurality of air outlet nozzles 34, the plurality of air outlet nozzles 34 are annularly fixed on the rotating tube 33, a gear 35 is fixed on the surface of one end of the rotating tube 33 near the gun body 21, the rotating sleeve 31 is rotatably connected to the gun body 21, and one end of the rotating sleeve 31 is arranged to extend out of the gun body 21, and an inner ring 311 meshing with the gear 35 is arranged on the inner ring of the rotating sleeve 31 extending out of the gun body 21;

[0020] In order to avoid scalding the staff, the surface of the rotating sleeve 31 and the surface of the air outlet pipe 22 are coated with high-temperature resistant heat-insulating coating. The high-temperature resistant heat-insulating coating is a new material derived from space technology used for thermal insulation of spacecraft. It has many advantages such as waterproof, fireproof, corrosion-resistant, wear-resistant, and insulating. The coating uses the latest nano-ceramic technology, and the insulation efficiency can reach more than 90%. The surface of the rotating sleeve 31 is also wrapped with a high-temperature resistant layer cover 6.

[0021] Reference Figure 2 and Figure 3 The length of the center rod 32 is greater than the length of the air outlet pipe 22. The surface of one end of the center rod 32 away from the gun body 21 is a threaded rod, and an adjusting nut 4 is threadedly connected to the threaded rod. One end of the adjusting nut 4 abuts against the end of the rotating tube 33, and a friction plate is glued and fixed on the surface of the adjusting nut 4 in contact with the rotating tube 33.

[0022] In order to prevent the air outlet nozzle 34 from being displaced during operation, the nut 4 is adjusted to abut against the end of the rotating tube 33 to apply friction to the rotating tube 33 .

[0023] Reference Figure 3 In order to reduce the gap between the air outlet nozzle 34 and the air outlet pipe 22, a plurality of adjustment pads 5 are adhered to one end of the air outlet nozzle 34 close to the air outlet pipe 22. An appropriate amount of adjustment pads 5 are adhered as needed to reduce the gap between the air outlet nozzle 34 and the air outlet pipe 22, thereby reducing the leakage of hot air.

[0024] The implementation principle of a hot air station for processing a stepper motor driver in the embodiment of the present application is as follows:

[0025] When it is necessary to use air outlet nozzles 34 of different calibers, the staff only needs to hold the gun body 21 with one hand and rotate the rotating sleeve 31 with the other hand. The inner gear ring 311 on the rotating sleeve 31 can drive the rotating tube 33 to rotate via the gear 35, thereby rotating the air outlet nozzle 34. The air outlet nozzle 34 to be used can be rotated to the end of the air outlet pipe 22, which is convenient for adjustment.

[0026] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, principle and application direction of the present application should be included in the protection scope of the present application.
