Description

A kind of patch frock

Technical field

It the utility model is related to mount technology field, more particularly to a kind of patch frock.

Background technology

In the patch processing of various metal substrates, if reasonable utilization frock is used cooperatively, it will substantially reduce processing Cost.Such as：Production work in the copper base paste solder printing without clamping technique edges, SMT patches and connection sheet welding auxiliary manufacture Skill mainly has the following steps and (generally requires 6 stations to complete)：

(1) copper base of jigsaw carries out crossing Reflow Soldering for the first time by SMT patches (component)；

(2) copper base for completing patch carries out V-CUT and is divided into unit copper base；

(3) unit copper base loads positioning tool；

(4) manually at syringe point tin cream copper base pad；

(5) high tempreture tape manually is pasted in connection sheet, prevents from climbing tin；

(6) positioning tool of (3) on chip step is connected, ceiling molding clamps, and carries out second and crosses Reflow Soldering.

Existing copper base SMT production technologies are primarily present following defect：

(1) number of copper base V-CUT is excessive；

(2) manually point tin cream efficiency is slow, and tin amount is uneven；

(3) product second reflow, has hidden danger to quality；

(4) transfer of production station is more, and efficiency is low, of high cost.

In summary, the copper base paste solder printing, SMT patches and connection sheet welding auxiliary manufacture, exist not in practice Just the problem of, so it is necessary to be improved.

Utility model content

The purpose of this utility model is to provide a kind of patch frock, reduces frock, station, V-CUT quantity, and patch is latter Secondary Reflow Soldering can just be welded component and connection sheet, avoid secondary stove of crossing from causing product quality risk.

To achieve the above object, using following technical scheme：

One kind is used for patch frock, including upper cover, bottom plate, some magnet, at least an at least pressing plate, a catch；On described First through hole is opened up among lid；The width of the pressing plate along upper cover is arranged on its bottom；The catch slides and vertical peace Mounted in pressing plate end；The magnet symmetry is embedded in the lower surface of upper cover and the upper surface of bottom plate.

It is preferred that both sides open up the parallel ventilation hole of two row to the bottom plate along its length；The length direction of the upper cover Both sides open up a row ventilation hole, and are corresponded with the one row ventilation hole of inner side of bottom plate.

It is preferred that the pressing plate is arranged to two；The catch is arranged to four；The pressing plate both ends are passed through with upper cover respectively Screw welds；The catch opens up chute hole along central axis direction；The catch is through its chute hole in pressing plate and the screw of upper cover Between slide.

It is preferred that the patch frock further includes some first positioning columns；Some first positioning columns, which correspond to, to be distributed in The lower surface of upper cover and the upper surface of bottom plate, for being positioned to material.

It is preferred that the patch frock further includes some second positioning columns；Some second positioning columns are arranged at upper cover Lower surface；The bottom plate corresponds to the second positioning column position and sets some second location holes.

It is preferred that the upper cover and bottom plate are aluminium material.

It is preferred that the magnet is high temperature resistant magnet.

Using the above scheme, the beneficial effects of the utility model are：

1) frock quantity is saved, 1 set of frock is (existing with regard to that can complete paste solder printing, patch, connection sheet welding procedure Need 3 sets of frocks)；

2) reduce station number, only need 2 stations (existing at least to need 6 stations) at this stage, save manually into Sheet and production occupied space cost；

3) reduce process, station transfer, without switching frock, in a SMT line with regard to work can be completed, improve Work efficiency, reduces human cost；

4) press printing tin cream is used, tin cream amount is uniform and uniformity is good, and a Reflow Soldering just can be first device after patch Part and connection sheet are welded, and avoid secondary stove of crossing from causing product quality risk；

5) reduce V-CUT number, 2 scoreboards with regard to can split unit copper base (according to the needs of frock, the spelling to substrate The mode of connecing is improved).

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.

Referring to figs. 1 to shown in 7, the utility model provides one kind and is used for patch frock, including upper cover 2, bottom plate 1, some magnetic Iron 3, at least a pressing plate 4, at least a catch 5；First through hole 21 is opened up among the upper cover 2；Width of the pressing plate 4 along upper cover 2 Degree direction is arranged on its bottom；The catch 5 slides and is vertically mounted on 4 end of pressing plate；3 symmetry of magnet is embedded in The lower surface of lid 2 and the upper surface of bottom plate 1.

Wherein, both sides open up the parallel ventilation hole 22 of two row to the bottom plate 1 along its length；The length side of the upper cover 2 A row ventilation hole 22 is opened up to both sides, and is corresponded with the one row ventilation hole 22 of inner side of bottom plate 1.The pressing plate 1 is arranged to two It is a；The catch 5 is arranged to four；Welded respectively with upper cover 2 through screw at 4 both ends of pressing plate；The catch 5 is along central shaft side To opening up chute hole；The catch 5 is slided through its chute hole between pressing plate 4 and the screw of upper cover 2.

The patch frock further includes some first positioning columns 6；Some first positioning columns 6, which correspond to, is distributed in upper cover 2 Lower surface and bottom plate 1 upper surface, for being positioned to material.The patch frock further includes some second positioning columns 7； Some second positioning columns 7 are arranged at 2 lower surface of upper cover；The bottom plate 1 corresponds to 7 position of the second positioning column and sets some second Location hole 8.The upper cover 2 and bottom plate 1 are aluminium material.The magnet 3 is high temperature resistant magnet.

Utility model works principle：

The utility model is illustrated by taking copper base as an example.
