Technical field
The utility model relates to electron device package technology, is specifically related to a kind of parallel seam welding frock of electromagnetic location.
Background technology
Along with the development of hyundai electronics information technology, electronic device is rapidly to miniaturization, chip type future development.The plurality of advantages such as hydrid integrated circuit is wide in variety with it, reliability is high, volume is little are widely used in all kinds of military-civil field.Parallel seam welding technology is one of main seal technology of the highly reliable hydrid integrated circuit of current hermetic seal, but because the sagging mechanical action of two lateral electrodes can not Complete Synchronization in welding process, often cause on one side electrode contact time capping slight deflection, make product seal decrease in yield.
For addressing this problem, parallel seam welding operating personnel often adopt the way of the light squeeze cap of the instruments such as tweezers to locate to make capping, during to ensure that electrode is sagging, capping can not displacement, if but in operating process handheld tool slight jitter still likely cause capping deflection, cause airtight quality defective.
Utility model content
For defect or the deficiency of prior art, the purpose of this utility model is the parallel seam welding frock providing a kind of electromagnetic location, compresses problem to solve capping in parallel seam welding process.
For achieving the above object, the technical solution of the utility model is as follows:
A parallel seam welding frock for electromagnetic location, comprising:

One is positioned at the iron core on pedestal, and described iron core is connected on pedestal by securing member,
One yoke being set in parallel in iron core both sides, described iron core is consistent with the height of yoke, and the top of iron core and yoke is provided with end cap, and one is wound in the coil on iron core, and coil is fixed in the cavity that iron core and yoke form by described end cap;
Also comprise a flat head be connected with iron core, described flat head is provided with locating piece, and above locating piece, slip is provided with capping; Produce the stabilizing magnetic field perpendicular to capping plane after described coil electricity, and make capping produce downward constant electromagnetic suction.
In a preferred embodiment of the present utility model, described locating piece both sides are also provided with frid, and described frid is corresponding with yoke position, and magnetic field enters yoke formation loop by frid radiation.
In a preferred embodiment of the present utility model, described end cap is that non-magnet_conductible material is made.
In a preferred embodiment of the present utility model, described iron core is connected with cable, and described cable connects DC driver.
By technique scheme, the beneficial effects of the utility model are:
The utility model adopts DC driven mode, can realize location electromagnetic attraction and stablize; Adopt soft magnetic metal material simultaneously and be bonded closed magnetic path without magnetic structural metal parts, both coil had been facilitated to go the taking-up of the rear welded part of electricity, have and to greatest extent electromagnetic field is enclosed in frock inside, to avoid the materials such as space stray magnetic field adsorption tooling periphery magnetic parts and magnetic fifth wheel.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
With reference to figure 1, the parallel seam welding frock of a kind of electromagnetic location of this embodiment, comprises iron core 1, pedestal 2, yoke 3, coil 4, end cap 5, frid 6, locating piece 7, workpiece to be added 8, capping 9, cable 10, flat head 11.
Particularly, a kind of parallel seam welding frock of electromagnetic location, comprise a pedestal 2, and be positioned at iron core 1 on pedestal 2, described iron core 1 is connected on pedestal 2 by securing member,
One yoke 3 being set in parallel in iron core 1 both sides, described iron core 1 is consistent with the height of yoke 2, and the top of iron core and yoke is provided with end cap 5, and one is wound in the coil 4 on iron core, and coil 4 is fixed in the cavity that iron core 1 and yoke 3 form by described end cap 5;
Also comprise a flat head be connected with iron core 11, described flat head 11 is provided with locating piece 7, and above locating piece 7, slip is provided with capping 9; Produce the stabilizing magnetic field perpendicular to capping 9 plane after described coil 4 is energized, and make capping 9 produce downward constant electromagnetic suction.
Further, locating piece 7 both sides are also provided with frid 6, and described frid 6 is corresponding with yoke 3 position, and magnetic field enters yoke formation loop by frid radiation.When specific works, locating piece 7 put into by workpiece 8 to be added.
Further, iron core is connected with cable, and described cable connects DC driver, and DC driver produces constant current, makes to realize location electromagnetic attraction and stablizes.
Produce magnetic field after coil 4 is energized, iron core 1, pedestal 2, yoke 3, coil 4, frid 6, locating piece 7, capping 9, flat head 11 are soft magnetic metal part and form closed magnetic circuit, and end cap 5 is aluminium alloy or other non-magnet_conductible materials.
The magnetic circuit course of work is: during coil energization, and the magnetic field that coil 4 produces conducts to flat head 11 through iron core 1, and due to end cap 5 not magnetic conduction, magnetic field, flat head 11 upper surface successively enters capping 5 and locating piece 7 to space radiation, then conducts to frid 6 by locating piece 7.
Frid 6 and yoke 3 have larger right opposite and amass, and magnetic field enters yoke 3 by frid 6 radiation and forms loop.Have two air gaps in whole magnetic circuit, one is the breath between flat head 11 and capping 9, and another is the breath that non-magnetic end cap 5 is formed.Wherein to amass large magnetic resistance little for capping 9 and flat head 11 upper surface right opposite, and magnetic field, along the little path conduct radiation of magnetic resistance, produces downward electromagnetic attraction to capping 9, realizes the location to capping 9.
Seam is soldered into rear coil and goes electromagnetic field to disappear, and the electromagnetic attraction of capping 9 also disappears, and can take out soldering and sealing workpiece smoothly with instruments such as tweezers, completes parallel seam welding operation.
Adopt aforesaid way, the sagging asynchronous weldment caused of parallel seam sealing machine two lateral electrode can be eliminated and move deflection, it also avoid manual pressure in welding process and weldment may be caused to move, ensure that welding uniformity, parallel soldering and sealing quality can be improved.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
