Description
Technical field
The utility model relates to a kind of parcel plating device.
Background technology
As shown in Figure 1, in the semicon industry, the electronic element 603 that a lot of equipment must use, it comprises pin 602, before use, need carry out the electroplating surface processing to electronic component 603 and pin 602.Because be applied in the semiconductor technology such as unicircuit, the volume of electronic element 603 and pin 602 is often very little.For adapting to needs of scale production; use limit muscle 604 with a plurality of electronic elements 603 with after pin 602 is connected; and on limit muscle 604, offer through hole 601; to overlap more and need galvanized electronic element and pin to electroplate in batch using a plurality of hooks on the hook carriage to pass through hole 601, limit muscle, electronic element and pin are collectively referred to as lead frame.Therefore, the limit muscle only is to use when lead frame is electroplated, and needs to cut away after plating is finished.As shown in Figure 2, the electroplating device that uses in the prior art, comprise electric bath groove 1 and hook (not shown), many group hooks are arranged on the hook rack 2 along arranging with the liquid level vertical direction, a plurality of lead frames 6 hang on the hook successively, and lead frame 6 also is along being arranged in parallel with liquid level vertical direction B (depth direction of electric bath groove just).During plating, for guaranteeing the electroplating effect of top lead frame, each hook and lead frame all are immersed in the electric bath groove, hook connects power supply one utmost point, anode is set in the electroplate liquid connects another utmost point of power supply, after the energising, the metallic cation in the electroplate liquid is subjected to lead frame to attract to converge on the lead frame, finishes plating.Though this equipment also can realize electroplating function, in electroplating process, muscle part in limit also is to be made by electro-conductive material, therefore, in electroplating process, also can electroplate layer of metal on the muscle of limit.And when reality was used, the limit muscle partly needed excision.Like this, the opposite side muscle is partly electroplated and has just been caused waste, has increased material cost, and the processing after the parcel plating of opposite side muscle also becomes thorny problem, directly abandons and will cause environmental pollution, as handle, need corresponding technology, increased processing links, then increase cost once more.And in hook and the equal immersion plating liquid of hook rack, hook rack and hook adopt electro-conductive material to make, and after its energising, also can electroplate the layer of metal material on hook and the hook rack, like this, electroplate in hook rack and hook surface, can waste plated material equally.Recycle as linking up with, after having electroplated a collection of lead frame, need carry out the strip processing, remove the metallic substance that its surface plates hook and hook rack with hook rack.Like this, the one, wasted plated material, the material of hook and hook rack electroplating surface accounts for more than 25% of employed plated material in the whole technological process, just will waste the plated material more than 25%; The 2nd, increased aftertreatment technology to hook and hook rack, make the whole process time prolong, efficient reduces.
The utility model content
The purpose of this utility model is in order to overcome deficiency of the prior art, a kind of parcel plating device that reduces plated material and water resource waste to be provided.
For realizing above purpose, the utility model is achieved through the following technical solutions:
The parcel plating device comprises electric bath groove, is provided with anode in the electric bath groove, it is characterized in that, also comprise hook carriage and two groups of above hooks, described hook is installed on the hook carriage, and two groups of above hooks are arranged along the direction parallel with the electroplate liquid liquid level.
Above-mentioned more than two groups, its implication comprises two groups.
Hook and hook carriage can adopt electro-conductive material to make, and during plating, only need the hook carriage is connect power supply one utmost point, can be energized to lead frame and electroplate.Adopt non-conducting material as hook and hook carriage, then use lead to switch in addition as lead frame.
Preferably, every group of hook number is two or more, two or more hook linear arrangement, and every group tangles a lead frame.Preferably, two hooks are one group, tangle a lead frame jointly.
Preferably, described hook carriage comprises frame parallel more than two and at least one crossbeam, two connect as one by crossbeam with upper side frame, hook is installed on the frame, and per the hook more than two is one group, lays respectively on the plural frame, described hook number is more than two groups, two groups of above hooks are arranged along the direction parallel with the electroplate liquid liquid level, and crossbeam or side frame are on the cell wall of electric bath groove
Preferably, also comprise the setting device that to adjust distance between liquid level and the cable address hook.
Preferably, described setting device is overflow groove or the overflow weir that is arranged on the electroplate liquid cell wall.
Preferably, described anode is the net formula.
Parcel plating device in the utility model, can make hook and the height of electroplating liquid level keep definite value, just can make when lead frame is electroplated needs galvanized part to be immersed in the electroplate liquid, electrode and limit muscle etc. do not need galvanized part can remain on more than the plating liquid level, in electroplating process, hook, hook carriage and limit muscle part can not plate plated material, reduced waste of material, and reduced the aftertreatment technology of limit muscle, electrode and hook carriage, both save material, simplified aftertreatment technology again.And, electroplated a collection of lead frame after, need not that hook carriage and hook are carried out strip and handle the plating just can proceed the next batch lead frame, saved the time, improved efficient.
Parcel plating device in the utility model is meant and can only electroplates need plated item surface, as to lead frame, just can only electroplate electronic element and pin.
The beneficial effects of the utility model are: easy to use, can only carry out parcel plating to lead frame, save material, use the parcel plating device in the utility model, can save plated material at least more than 25%, and saved aftertreatment technology, simple to operate, save time the efficient height, and device structure is simple, makes easily.
