The invention discloses an integrated heating-placement hot air head which is characterized in that a heater fixing seat and a heater support are arranged between an upper fixing plate and a lower fixing plate; a nozzle holder is arranged at the bottom of the lower fixing plate; a hollow sucking rod guiding sleeve is arranged in the upper fixing plate in a penetrating way; the lower end of the sucking rod guiding sleeve extends into the heater fixing seat; a rotating induction coil is arranged at the upper part of the sucking rod guiding sleeve; a sensor is also arranged beside the rotating induction coil; a rotating driving rod is arranged between the rotating induction coil and the sucking rod guiding sleeve; the sucking rod guiding sleeve is connected with a rotating rod; a sucking rodenters from the rotating induction coil, penetrates the sucking rod guiding sleeve and extends out of the nozzle holder; and a suction nozzle is also arranged at one end of the sucking rod outside the nozzle holder. The hot air head disclosed by the invention has the advantages of simple and reasonable structure, small volume, low cost, uniform heating temperature, rapid heating and cooling, longservice life, excellent heat resistance, low heat loss, capability of ensuring placement accuracy and reliability, and convenient installation and maintenance.
Description
Technical field [0001] The present invention involves the technology field of printing circuit board welding machines, especially a heating and fitting integrated heat. Background technique [0002] The existing printing circuit board welding machine still has the following shortcomings: (1) Due to the failure of heating and paste mechanisms (independence), the product volume is large, and a certain space needs to be occupied.High, and affecting work efficiency; (2) The heating wires in the hot air head, the temperature is uneven, the temperature heating / cooling is slow, and the heat of the heating wire is not good; (3) the existing hot air, its hot air can not directly act on the chip on the chip, Its heat loss is large and it is difficult to achieve infrared heating; (4) Affected by the traditional vacuum access method, the micro -movement of the rod is easily affected by the vacuum access tube, which is difficult to ensure the accuracy and reliability of the paste; (5)The rod ...
