Abstract
The utility model provides an adjustable hot air cover, mainly comprising an automatic guide cover and a hot air cover; wherein, the surface of the automatic guide cover is provided with a first guide body, the bottom of the automatic directional cover is provided with an exhaust hole; the hot air cover is provided with a secondary guide body corresponding to the first guide body. The hot air cover is invaginated in the automatic guide cover and makes a relative sliding movement to the automatic guide cover at the direction of getting close to or getting far away from a circuit board, enabling the hot air cover to be hung above the circuit board. The device reduces the distance between the circuit board and the hot air cover through the automatic guide cover, thereby preventing the hot air from directly pressing on the surface of the circuit board, and avoiding the circuit board being pressed broken and affecting the return repair quality. The circuit board is fuuly heated by hot air, and the air can be exhausted from the heating fully the circuit board, and the vent gas going out from the exhaust hole, thereby ensuring the heating air temperature curve so as to achieve a stable heating effect.
Description
[technical field]
The utility model relates to a kind of adjustment type air bells cap, particularly relates to a kind of device that certain part on the circuit board is evenly heated.
[background technology]
Along with the development of electronic product to miniaturization, portability, networking and high-performance direction, circuit assembling, maintenance technique and I/O pin count are had higher requirement, the volume of chip is more and more littler, and the pin of chip is more and more, gives and produces and reprocess and brought difficulty.
All BGA element rework equipments all are to adopt hot type up and down at present, and the top all is to adopt the hot blast heating.And the air bells cap body of top all is an integral body, the height of air bells cap is unadjustable, can better cover the BGA that is overhauled for air bells cap like this, all be to realize in whole implementation process by regulating machine, there is the stroke of the air bells cap of a lot of machines all to fix, such shortcoming has: (1) is regulated the distance of air bells cap and PCB and will be finished by regulating machine, and the adjusting time is long like this; (2) if the distance of air bells cap and PCB is too little, touch PCB, have big pressure, make the PCB distortion, quality is reprocessed in influence; (3) distance of air bells cap and PCB is fixing, when particularly distance is big, may be by factor affecting temperature curves such as extraneous air-flow, hot gas gas flows, thus have influence on the hot blast heats.
[summary of the invention]
The purpose of this utility model provides a kind of adjustment type air bells cap, is a kind of discharge stability of guaranteeing hot blast, makes heats strengthen, and it utilizes the lower end to have the slidably automatic guide cover of steam vent.
The utility model provides a kind of adjustment type air bells cap, consists predominantly of automatic guide cover, air bells cap, and this automatic guide cover is provided with first guide body, and the bottom is provided with steam vent; Air bells cap is provided with second guide body, and is corresponding with the first guide body position, and air bells cap is placed in the automatic guide cover, with the automatic guide cover do with respect to circuit board near and away from direction slide.
Further include, the air bells cap cover body amount of being provided with line is controlled the distance of air bells cap and circuit board according to measuring the line scale when air bells cap slides in the automatic guide cover.
Structure compared to prior art, increases an automatic guide cover between circuit board and air bells cap as mentioned above, by the automatic guide cover air bells cap needn't directly be contacted with circuit board, can regulate machine very easily like this, reduces the adjusting time; Also prevent air bells cap contact circuit plate, only allow automatic guide cover contact circuit plate, the pressure that the direct contact circuit plate of the pressure ratio air bells cap of its generation produces is little, does not have influence to reprocessing quality; Hot gas is fully heated circuit board, and gas evenly overflows from steam vent, guarantees the temperature curve of heated air, thereby reaches stable heats.

[embodiment]
Ginseng Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, the utility model consists predominantly of air bells cap 1, automatic guide cover 2 etc. for adjusting air bells cap.Automatic guide cover 2 is placed in air bells cap 1 cover body outside, and the outer surface of air bells cap 1 is close to the inner surface of automatic guide cover 2, and both gaps do not influence heats.Air bells cap 1 is provided with some second guide body, 11, the second guide body 11 and can be difformity, and second guide body 11 is the gathering sill structure of long and narrow arc in this embodiment.
The air bells cap 1 cover body amount of being provided with line 12, its marking scale direction is consistent with the air bells cap direction of motion.Automatic guide cover 2 is provided with some first guide body 21, first guide body comprises fixing hole 211 and immobilising device 212, immobilising device 212 passes fixing hole 211, see through second guide body 11, immobilising device 212 can be done slide relative in second guide body 11, by the fixing relative position of automatic guide cover 2 and air bells cap 1 of this structure, automatic guide cover 2 is slided freely along the direction of second guide body, 11 guide channels in the air bells cap 1; The bottom of automatic guide cover 2 cover bodies is provided with plurality of rows pore 22, and steam vent 22 is the angle of opening 45 degree in this example, by steam vent 22 hot gas is discharged rapidly to circuit board 3 heating backs.
During enforcement, automatic guide cover 2 is downward naturally, its bottom is contact circuit plate 3 directly, and cover on fully and be heated parts 31 on the circuit board 3, air bells cap 1 slides to the direction near circuit board 3 under the effect of interfixing of first guide body 21 and second guide body 11, throughput line 12 represented scales, the distance of control air bells cap 1 and circuit board 3, make not contact circuit plate 3 of air bells cap, also can guarantee heats.
The utility model is not limited to this embodiment, and the utility model content all can be implemented.
