Abstract

A heat gun head comprises an outer casing, wherein two rows of air outlets communicated with the inside of the outer casing are formed in one end of the outer casing; hot air in the outer casing can be blown out through each air outlet. According to the invention, the two rows of air outlets are formed in the heat gun head, and can be aligned to various pins of a chip respectively, and the soldering tin of the pins can be melted simultaneously to facilitate dismounting the chip.

Description

Heat gun head

Technical field

The present invention relates to a kind of heat gun head.

Background technology

The head of existing heat gun is normally only provided with an air outlet, and when circuit board is pulled down chip, heat gun makes its fusing to the scolding tin blowing hot-air of the pin of the both sides of chip in turn, thereby conveniently takes off chip.Yet the different pins of chip are heated and are inhomogeneous, the scolding tin of some pins just melts, and previously the scolding tin of fusing had been tending towards solidifying, was inconvenient to carry out the sealing-off operation of chip.

Summary of the invention

In view of above content, be necessary to provide a kind of heat gun head that can chip for convenience detach.

A heat gun head, comprises a shell, and one end of shell is provided with the air outlet that two row are communicated with the inside of shell, and the hot blast in shell can blow out from each air outlet.

This heat gun head is provided with two and lists air port, and these air outlets can align respectively each pin of chip, and the scolding tin of these pins is melted simultaneously, is conducive to pull down chip.

Main element symbol description

The following specific embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.

The specific embodiment

Please refer to Fig. 1 and Fig. 3, the better embodiment of heat gun head of the present invention is for pulling down the chip 100 that is welded in circuit board.Chip 100 comprises a body 101 and is located at some pins 102 of the both sides of body 101.Heat gun head comprises a shell 10, a transmission mechanism 20 and an actuating mechanism 30.

Shell 10 comprises the head 11 of an interior sky and is arranged on a columnar neck 16 of the rear end of head 11.The middle part of the leading flank 112 of head 11 is provided with a groove 12.Head 11 is run through at the two ends of groove 12.The opening 122(that the two ends of groove 12 are respectively provided with the inside of a connection head 11 is shown in Fig. 2).Head 11 rotates respectively in the two ends of groove 12 installs a fixture block 13.The two ends of groove 12 are respectively provided with the pivot rods 125 of two relative sidewalls 123 of a connecting groove 12.This two pivot rods 125 is arranged in respectively this two fixture block 13, makes this two fixture block 13 be rotationally connected with this two pivot rods 125.The inner side of each fixture block 13 projects a catch 131 in diapire 126 places away from groove 12.The outside of each fixture block 13 projects a limiting section 132.The leading flank 112 of head 11 is respectively provided with the air outlet 15 of the inside of some connection heads 11 that form a line in the both sides of groove 12.This two is listed between air port 15 and aligns one by one from left to right.The outside of neck 16 is provided with the chute 18 of inside of the connection neck 16 of a leading flank 112 perpendicular to head 11.

Transmission mechanism 20 comprises that the both sides of the leading flank 112 perpendicular to head 11 that is positioned at neck 16 are equipped with a catch bar 21 of some latches 211, are positioned at two gears 22 that are meshed with latch 211 and an action bars 23 of the both sides of catch bar 21.Each gear 22 center installing one connects the axle 222 of the inwall 162 of neck 16.Action bars 23 extends and is arranged in slidably chute 18 from catch bar 21.Action bars 23 is provided with the inwall 162 of a butt neck 16 and hides the windshied part 232 of chute 18.

Actuating mechanism 30 comprises that a connecting portion roughly taking the shape of the letter U 301 and two is the shell fragment 33 of the arc protruding forward.Connecting portion 301 comprises a connecting piece 31 of the front end that connects catch bar 21 and two Extendible flakes 32 that extend forward from the both sides of brace 31.This two shell fragment 33 extends outward from the front end of this two Extendible flake 32 respectively.This two shell fragment 33 passes respectively the rear end of the inner side of this two fixture block 13 of the rear connection of this two opening 122.The outside of each Extendible flake 32 is provided with a compression leg 35 with the junction of corresponding shell fragment 33.

During use, these air outlets 15 of heat gun head are aligned respectively to these pins 102.Open the heat gun that this heat gun head is corresponding, hot blast blows out from these air outlets 15 after flow through neck 16 and head 11.The hot blast that these air outlets 15 blow out blows to these pins 102 simultaneously, and the scolding tin of these pins 102 is melted simultaneously.Close heat gun, stir forward action bars 23, make catch bar 21 reaches, this two gear 22 rotates.These connecting portion 301 reaches, this two shell fragment 33 is out of shape and pulls the rear end of this two fixture block 13, and this two fixture block 13 is opened relatively.The body of chip 100 101 is contained in to groove 12 and between this two fixture block 13.Pull back action bars 23, these two shell fragments, 33 elastic recoverys, connecting portion 301 and catch bar 21 reset.This two fixture block 13 folds and clamps the body 101 of chip 100, thereby chip 100 can be taken away from circuit board, and this two catch 131 can prevent that chip 100 from skidding off forward.Each fixture block 13 cannot continue outside rotation while outwards turning to the lateral surface of corresponding limiting section 132 butt heads 11, and then avoids this two shell fragment 33 because being out of shape the excessive elasticity of losing.

In the present embodiment, this two gear 22 moves catch bar 21 comparatively reposefully.In other embodiments, this two gear 22 can omit, and catch bar 21 can not established latch 211.
