Description

Technical Field

[0001] The utility model relates to the technical field of hot air guns, in particular to an intelligent dual-station replaceable-core hot air gun desoldering station. Background Technique

[0002] Hot air guns are widely used in many fields such as electronic repair, plastic welding, heat shrink packaging, paint drying, etc. In the electronic field, they can be used for the welding and disassembly of electronic components, and provide convenience for desoldering with their unique characteristic of generating high-temperature hot air.

[0003] Currently, the hot air gun desoldering stations on the market usually use high voltage to directly heat the resistance wire, adjust the turbine speed through a turbine fan to control the hot air volume, and use the temperature sensor at the front end of the heating core rod to measure the temperature and feedback it to the control unit to achieve temperature and air volume control. However, there are many problems with existing hot air guns: First, the handle and heating wire of the hot air gun are non-pluggable and fixed, resulting in high daily maintenance costs. If the air duct of the hot air gun is damaged, it needs to be returned to the factory for replacement as a whole, and the heating core cannot be replaced by itself, making it difficult to change the heating power and the size of the air duct. Second, most are single-handle designs currently, but the chip specifications in electronic products are diverse, and maintenance personnel often need to purchase multiple hot air gun stations for combined repair and welding work. Third, the heating cores of existing hot air guns often use the winding method of winding resistance wires around a ceramic air duct with six or eight holes, which will cause turbulence to the air flow. If a blower with a larger air volume is not used, the hot air volume will be blocked by the ceramic rod and the resistance wire and cannot flow quickly to the heating nozzle, resulting in insufficient heating power. Fourth, existing hot air guns all use a single temperature sensor to measure the temperature, resulting in problems such as inaccurate temperature measurement and deviation, and usually cannot monitor the problem of temperature backflow. Generally speaking, problems such as non-replaceable handles, non-replaceable heating cores, inconvenient replacement of the nozzle due to high temperature during operation and easy skin burns, the need to combine multiple hot air gun stations for repair and rework, resulting in increased purchase costs, occupying a large amount of desktop space during use and easy confusion of handles, etc., bring a lot of troubles to the repair personnel. At the same time, there are defects in the heating method and temperature measurement method of existing hot air guns, affecting their performance and use effect. Therefore, there is an urgent need for an intelligent dual-station replaceable-core hot air gun desoldering station to solve the above multiple problems. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1 to 5, showing a smart dual-station replaceable-core hot air gun desoldering station provided by an embodiment of the present invention, including a hot air gun, a hot air gun base 2 and a control host 3.

The hot air gun handle silicone tubes 4 corresponding to each hot air gun handle 11 are provided in a matching manner. The sizes of the two hot air gun handle silicone tubes 4 can also be the same or different. For example, the diameters or lengths of the two hot air gun handle silicone tubes 4 can be the same or different. When batch desoldering components of the same specification, the two hot air gun handles 11 are selected to have the same size, and the work efficiency is high. When it is necessary to desolder multiple specifications of components at the same time, the two hot air gun handles 11 can be selected to have different sizes to desolder simultaneously, with strong adaptability. The hot air gun handle silicone tube 4 is preferably a high-temperature resistant rubber tube.

[0030] Specifically, the heating component 12 includes a heating wire 121 and a heating bracket 122.

[0037] In some specific embodiments, the heating tube 123 is preferably made of stainless steel. The heating tube 123 and the front-end metal on the hot air gun handle 11 form a circuit. When the hot air gun handle 11 is inserted into the hot air gun base 2, the handle ring contacts the sleep handle bracket, and the two are short-circuited, generating a sleep signal and feeding it back to the control host 3, so that when the hot air gun is placed on the hot air gun base 2, it can automatically pause the heating function and enter the intelligent sleep state, saving energy and avoiding accidentally injuring the operator due to always maintaining the heating state.

[0038] More specifically, the hot air gun handle 11 is further provided with a hot air gun start button, a hot air gun heating button and a hot air gun cooling button. The hot air gun start button is connected to the switch power supply 34. The hot air gun heating button and the hot air gun cooling button are connected to the temperature control system.

Thus, the heating power can be adjusted according to actual needs. Moreover, the heating tube 123 can also be replaced with different models of different sizes, thereby enabling the control of the size of the unit air output volume, meeting the repair requirements of various chip specification sizes, greatly improving the applicability of the hot air gun.
