Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a reflow soldering stove is used in carrier band production as shown in fig. 1-4, including reflow soldering stove base member 1 and heat dissipation case 3, the bottom of reflow soldering stove base member 1 is equipped with four at least stabilizer blades 4, and the surface of stabilizer blade 4 has cup jointed the silica gel pad, can increase stabilizer blade 4's surface friction, makes the holistic steadiness of device obtain promoting.

A cover 2 is installed above a base body 1 of the reflow oven, a heat dissipation box 3 is installed on one side of the surface of the cover 2, and in order to enable air in the heat dissipation box 3 to effectively circulate so as to dissipate heat, a heat dissipation opening 31 is sequentially and uniformly formed in the surface of one end of the heat dissipation box 3. The heat dissipation box 3 comprises a shell 5 and a battery pack 12, a protection frame 13 is assembled outside the battery pack 12, a glass fiber layer is filled inside the protection frame 13, a heat insulation effect can be achieved, and adverse effects on the battery pack 12 caused by the temperature in the heat dissipation box 3 are avoided.

One side of shell 5 is passed through 6 cooperation screws of link and is installed fin 7, be equipped with mounting panel 8 on the inner wall of shell 5, mounting panel 8's surface is installed the intercommunication in proper order and is had first heat dissipation fan 9, second heat dissipation fan 10 and thermantidote 11, first heat dissipation fan 9 all includes damping rod and fan main part with second heat dissipation fan 10, first heat dissipation fan 9 all assembles through damping rod and fan main part with the central part of second heat dissipation fan 10, can play the shock attenuation and alleviate the effect, play the effect of making an uproar, the too big influence operational environment of noise of avoiding the heat dissipation work. The battery pack 12 is arranged inside the housing 5, the first heat dissipation fan 9 is electrically connected with the battery pack 12 through a circuit matched with the first thermosensitive switch 14, the second heat dissipation fan 10 is electrically connected with the battery pack 12 through a circuit matched with the second thermosensitive switch 15, and the cooling fan 11 is electrically connected with the battery pack 12 through a circuit matched with the third thermosensitive switch 16.
