Description
Technical field
The utility model relates to a kind of cleaning of lead frame manufacture field more particularly to discrete device lead frame folders
Tool.
Background technique
Discrete device is widely applied to consumer electronics, computer and peripheral hardware, network communication, automotive electronics, LED display
Equal fields.During punching production, discrete device inevitably touches punching oil, completes punching press and folding in this way
After curved, it is necessary to carry out ultrasonic cleaning.Since discrete device lead frame (such as figure one) is higher to dimension precision requirement, position
It sets tolerance and is generally ± 0.05mm, bending depth tolerances are generally ± 0.10mm and its structure is unique.In the process of cleaning
In slight mutual collision or all may cause deformation of products with cleaning container collision and exceed the range that tolerance allows.Therefore it needs
For the fixture of cleaning process design specialized to guarantee that product is intact during cleaning.Simultaneously some cleaning jigs its
Practicability is single, can only configure particular jig according to specific products, increase production cost.
Such as a kind of lead frame fixture of Publication No. CN205385014U.The lead frame fixture include connect liquid bath and
Clamping device.For the liquid bath that connects with vallecular cavity, the vallecular cavity for connecing liquid bath can contain the chemical pretreatment solution dripped on lead frame.
The clamping device is for clamping lead frame and is located at lead frame above the vallecular cavity.Lead provided by the utility model
Frame fixture, setting connect liquid bath and can receive the chemical pretreatment solution dripped on lead frame completely, avoid chemical treatment drop
It falls in the structures such as cylinder, guide rail and causes to corrode, to protect mechanical equipment while realizing clamping, middle rotating function, prolong
Service life is grown.Program design is complicated and universal poor, is not suitable for large-scale promotion and uses.
Publication No. CN102936745B semiconductor lead frame clamp for electric plating and the plating side with the fixture for another example
Method, only clamping opening part and semiconductor lead frame are conducted the bottom sheet of fixture by folder rib, rest part electrical isolation.It can avoid
Tin layers are plated on side muscle or middle muscle, save material, side muscle and middle muscle can be recycled directly；Easy to operate, process reduces production
And labour cost, production efficiency is improved, electroplating clamp strip process can be saved.The program is poor to the stationarity of lead frame,
Be not suitable for cleaning.
Utility model content
The purpose of this utility model is to solve the deficiencies in the prior art, provides that a kind of structure is simple, at low cost, applicability is wide
's.
The technical solution adopted in the utility model is: a kind of cleaning jig of discrete device lead frame, including top board
And lower pallet, the cavity that the top board and lower pallet are constituted is interior to be equipped at least four sponge strips, and the sponge strip passes through screw
It is connected with top board and lower pallet；The lower pallet is equipped with location hole, and the positioning hole is followed closely equipped with correcting, correcting nail positioning
The position of lower pallet, sponge strip and discrete device；The top board is connected with lower pallet by thumbscrew.
The correcting nail is furnished with plug screw as a further improvement of the utility model,.
The beneficial effect that the utility model uses is: the cleaning jig of this structure has the following characteristics that 1) guarantee deviding device
Part lead frame is indeformable in the process of cleaning；2) practical, according to the characteristic of different product come guide pin hole in alignment jig
Position, the use condition of most of discrete device may be implemented substantially；3) structure is simple, cooperates between each section part
Requirement it is lower, operate fairly simple；4) input cost is low.
Detailed description of the invention
Fig. 1 is discrete device lead frame schematic diagram.
Fig. 2 is discrete device lead frame side view.
Fig. 3 is utility model diagram.
Fig. 4 is the utility model side view.
It is as shown in the figure: 1 discrete device, 2 top boards, 3 lower pallets, 4 sponge strips, 6 correctings nail, 7 thumbscrews, 8
Plug screw, 9 screws.
Specific embodiment
Below with reference to Fig. 1 to Fig. 4, the utility model is described further.
As shown, a kind of cleaning jig of discrete device lead frame, including top board 2 and lower pallet 3, the upper pressure
Be equipped at least four sponge strips 4 in the cavity that plate 2 and lower pallet 3 are constituted, the sponge strip 4 by screw 9 respectively with top board 2
It is connected with lower pallet 3；The lower pallet 3 is equipped with location hole, and the positioning hole is equipped with correcting nail 6,6 positioning subiculum of correcting nail
The position of plate 3, sponge strip 4 and discrete device 1；The top board 2 is connected with lower pallet 3 by thumbscrew 7.
It for the work quality for further increasing this product, improves service life, the correcting nail is furnished with plug screw, passes through plug screw
Location hole is blocked, guarantees that correcting nail will not be cleaned liquid erosion.
The application method of the utility model is as follows, first stacks product, then with four sponge strips by the two of product
Side pressure is tight, then using correcting nail positioning, and is screwed sponge strip, is finally locked using thumbscrew, to complete whole
A clamping process.By facts have proved that this mechanism can be very good to guarantee that discrete device is indeformable during cleaning.And
This mechanism is not limited solely to one to two product.This mechanism can also make corresponding adjustment according to different products, to mention
Its high adaptability.When discrete device location hole difference, the diameter of adjustable correcting nail is adapted therewith with position；When point
When the bending depth difference of vertical device, it can come by adjusting the height of four sponge strips matching.The two collective effect, base
Originally it can satisfy the use condition of the discrete device of the overwhelming majority.
In the actual production process, operator is using simplicity, when discrete device type difference, it is only necessary to adjust by the present invention
The size of whole guide pin and the thickness of sponge strip can be applicable in most of discrete device, and mobility is stronger, has saved production
Cost, and the design very good solution of this fixture cleaning problem of discrete device lead frame, provide for product quality
It is effective to ensure.
1) cleaning jig of this structure, which has the following characteristics that, guarantees that discrete device lead frame is constant in the process of cleaning
Shape；2) practical, according to the characteristic of different product come the position in guide pin hole in alignment jig, most of point may be implemented substantially
The use condition of vertical device；3) structure is simple, and mutually matched between each section part to require lower, the comparison that operates is simple
It is single；4) input cost is low.
Those skilled in the art should know the protection scheme of the utility model is not limited only to the above embodiments, may be used also
To carry out various permutation and combination and transformation on the basis of the above embodiments, without departing from the spirit of the present invention,
The various transformation carried out to the utility model are all fallen in the protection scope of the utility model.
