Description

Multifunctional electric iron

The utility model relates to a kind of electric iron, specifically is a kind of modified multi-functional electric soldering iron.

Present existing electric iron can be divided into two kinds with regard to its basic function: a kind of is the common electrical flatiron; A kind of is the electric iron that welds the IC piece specially.The common electrical flatiron is simple in structure, but must be difficult to be fit to the welding of IC piece; Existing application-specific integrated circuit welding electric iron must be vacated a hand in use and take instrument to push down the IC piece, in order to avoid the IC piece is shifted or the IC piece is taken up when mentioning the die clamp soldering tip, because the IC piece often has a lot of pin, the connecting line on the circuit board is not only close but also thin, will cause quality problems because of carelessness; Existing in addition welding IC electric iron also needs to take in addition an instrument when circuit board takes off IC, from the die clamp soldering tip IC is taken out, and the time is long slightly just can be burnt out IC; The die clamp soldering tip is changed inconvenient.

The purpose of this utility model is the deficiency that overcomes in the prior art, provides a kind of simple in structure, plane welding or convenient, reliable when taking off IC, and the multifunction electric soldering iron of fast changeable die clamp soldering tip.

Structure of the present utility model comprises pusher button (1), spring (2), push rod (3), heat pipe (4), locking device (5), die clamp soldering tip (6), push rod (3) is positioned at the center of electric iron, heat pipe (4) is fixed in the electric iron by locking device (5), die clamp soldering tip (6) is connected on the heat pipe (4), die clamp soldering tip (6) is a hollow-core construction, its hollow parts and heat conduction caliber match, press pusher button (1), push rod (3) moves forward along axis, its fore-end protrudes in the end face of die clamp soldering tip (6), to realize fixing and to withdraw from the IC piece.

The utility model has the advantages that simple in structure, welding or convenient and reliable when taking off IC, fast convenient when changing the die clamp soldering tip, the service worker that can be suitable for e-factory production line operation workman and electronics, electrical apparatus industry, also be the desirable soldering appliance of radio amateur, be specially adapted to the operation of plane welding.

Below in conjunction with drawings and Examples structure of the present utility model is further described.

By accompanying drawing 1 as can be known, structure of the present utility model comprises pusher button (1), spring (2), push rod (3), heat pipe (4), locking device (5), die clamp soldering tip (6), heating wire (8), push rod (3) is positioned at the central part of electric iron, can be along axial-movement, push rod (3) is provided with two gears, control the fixing of IC piece or withdraw from the replacing of second gear realization die clamp soldering tip for first grade.Heat pipe (4) is fixed in electric iron inside by locking device (5), and the tube wall of heat pipe (4) has half garden connected in star, and the pellet shot from a slingshot of locking device (5) embeds and wherein fixes.Die clamp soldering tip (6) is connected on the heat pipe (4), presses pusher button (1), and push rod (3) is along axis reach, and its fore-end protrudes in the end face of die clamp (6), thereby realizes fixedly the IC piece and withdraw from the IC piece.

Die clamp soldering tip (6) is heated under the effect of heating wire (8), when carrying out plane welding IC piece, die clamp soldering tip (6) cover is pressed on the IC, after melts soldering tin, be about to pusher button (1) and shift first gear onto, push rod (3) is pushed down the IC piece downwards, and the IC piece is moved, simultaneously by means of reaction force, die clamp soldering tip (6) breaks away from the IC piece, treats that scolding tin solidifies, and can take away electric iron, spring (2) resets push rod (3), and each pin of IC piece is pressed on the circuit board with being flattened.

When need take off the IC piece, at first choose suitable standard die clamp soldering tip (6) according to the size and the model of IC piece, the die clamp soldering tip (6) that has heated is entangled the IC piece that will be removed, treat the melts soldering tin of each pin of IC piece after, can mention electric iron, this moment, the IC piece was clamped by die clamp soldering tip (6), pusher button (1) is pushed into a gear, and the head of push rod (3) just withdraws from the IC piece from die clamp soldering tip (6), and safety is taken off the IC piece, circuit can be do not injured, the IC piece can be do not damaged yet.

When needs are changed die clamp soldering tip (6), pusher button (1) is pressed to second gear, the particle size part or the prominent joint of push rod (3) just in time withstand heat pipe (4), stressed heat pipe (4) is open the pellet shot from a slingshot of locking device (5), heat pipe (4) and on die clamp soldering tip (6) together released by push rod (3), realize quick-replaceable purpose.

Push rod (3) can be designed to multiple version: for side-mounted, push rod (3) is prominent joint formula as the pusher button among Fig. 2 (1); Pusher button among Fig. 3 (1) is rear-mounted, and push rod (3) is prominent joint; Pusher button among Fig. 4 (1) is rear-mounted, and the thick section of push rod (3) is an open-core type; Pusher button among Fig. 5 (1) is rear-mounted, and push rod (3) is a hose type.Die clamp soldering tip (6) among Fig. 6 is designed to plurality of specifications according to size and the model of IC, to satisfy the welding needs of different sizes, model IC piece.When carrying out routine when welding, the single head soldering tip (6) among Fig. 7 or the double end soldering tip (6) among Fig. 8 need only be changed and get final product.Half garden connected in star of its soldering tip hollow part and half garden connected in star of heat pipe (4) match, and the pellet shot from a slingshot embedding of locking device (5) realizes fixing within it.
