Other metal strips.
In order to make the conveniently moving of the utility model, insulation handle is provided on the metal hanging rack.
In order to have good conductive property metal hanging rack and metal hanger, the metal hanging rack and metal hanger are used
The metal of red copper or other well conductings is made.
In order to make the utility model has the advantages of simple structure, manufacture be easy, if the metal hanging rack by a vertical metallic rod with
Dry transverse metal bar connection composition, the metal clamping jaw are fixed on transverse metal bar, and the metal hanger is fixed on vertically
The upper end of metallic rod.
The utility model compared with prior art, has the advantage that
Due to using, metal clamping jaw is vertical with metal hanging rack to be connect and metal clamping jaw is by least three bullets the utility model
Property metal strip composition structure, by the connection vertical with metal hanging rack of metal clamping jaw, for chip assembly and disassembly provide it is enough
Operating space keeps the assembly and disassembly operations of chip more convenient, while crowding around to form clamping jaw by a plurality of resilient metal strip, can be to crystalline substance
Piece provides enough chucking powers, and can reduce the percentage of damage of chip, and chip is convenient to mount and dismount, fast, is effectively promoted
Production efficiency reduces production cost.It is wrapped up on the position and metal hanging rack with contact wafers moreover, metal clamping jaw is removed
There is thermoplastic layer, hanger is prevented to be corroded in use by thermoplastic layer, effectively extends the service life of hanger, due to
Thermoplastic layer acid-alkali-corrosive-resisting, thus it is pollution-free to electroplate liquid.Also, several metal clamping jaws on metal hanging rack are uniform at equal intervals
Arrangement, to make uniform current density, ensure that thickness of coating is controllable.The utility model has the advantages of simple structure, manufacture is easy, uses
It is convenient and reliable.
The utility model will be further described below with reference to the accompanying drawings.Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, Electropolating hangers described in the utility model, including metal hanging rack 1 and are arranged on metal hanging rack 1
Metal hanger 2 and several metal clamping jaws 3.Wherein, metal hanging rack 1 is by a vertical metallic rod 11 and several transverse metal bars 12
Welding or screw connection by way of form, and each transverse metal bar 12 be present it is inferior be intervally arranged, every transverse metal
Multiple metal clamping jaws 3, and co-located metal clip are connected in such a way that welding or screw are fixed respectively on bar 12
Pawl 3 is symmetrically arranged with two, in order to make uniform current density, and then guarantees that thickness of coating is controllable, several metal clamping jaws 3 are at equal intervals
Uniformly arrangement.Moreover, the length of metal clamping jaw 3 is set according to the diameter of chip, the length of usual metal clamping jaw 3 is
30~100mm, preferably 50~80mm.Metal hanger 2 is then the upper end for being fixed on vertical metallic rod 11, in present embodiment
In, metal hanger 2 is integrated with vertical metallic rod 11 and connect.In use, metal hanging rack 1 is fixed on electrode by metal hanger 2
Electric action is gone up.Moreover, metal hanging rack 1 and metal hanger 2 are using purple in order to have good conductive property hanger main body
Copper or other good metals of guiding are made.
In order to provide enough operating spaces to the assembly and disassembly of chip, each metal clamping jaw 3 is vertical with metal hanging rack 1 respectively to be connected
Connect, i.e., as shown, the length direction of metal clamping jaw 3 is vertical with the length direction of transverse metal bar 12, and metal clamping jaw 3 with
Transverse metal bar 12 is located in same level.In order to be effectively reduced percentage of damage when chip clamping, each metal clamping jaw 3 respectively by
At least three resilient metal strip compositions for being intervally arranged and being fixed together by circumferencial direction.As shown, in present embodiment
In, each metal clamping jaw 3 is crowded around by three resilient metal strips formed respectively, and one end of three resilient metal strips is by being welded and fixed
Together, the other end surrounds clamping opening, and the shape of every resilient metal strip is identical, and is located at one end of clamping opening by being bent to form
The positioning groove for preventing chip from deviating from, while two resilient metal strips for being located at downside form upward support chip at a distance of relatively closely
Posture, prevent chip from falling between this two resilient metal strips.Moreover, in order to ensure metal clamping jaw 3 has good lead
Electrical property and clamping effect, resilient metal strip are stainless steel strip or copper bar or other metal strips.
In order to effectively extend the service life of hanger, reduce production cost, metal clamping jaw 3 is removed for contacting with chip 5
Position, remaining position are enclosed with thermoplastic layer 4.Meanwhile thermoplastic layer 4 is also enclosed on metal hanging rack 1.As shown, due to crystalline substance
Piece 5 is the outer end for being clamped in metal clamping jaw 3, therefore is that the outer end of metal clamping jaw 3 is not provided with thermoplastic layer.It is resistance in order to reach
The effect of acid and alkali corrosion, thermoplastic layer 4 are made of PE or PVC thermoplastic powder, preferably PE thermoplastic powder.
In order to make the conveniently moving of hanger, insulation handle 6 is provided on metal hanging rack 1.In the present embodiment, it insulate
Handle 6 is the top for being fixed by screws in vertical metallic rod 11, and the handle 6 that insulate is made of using metal, only in metal
It is equipped with thermoplastic layer and handle is made to be formed as the handle that insulate.Certainly, insulation handle 6 can also be fixed on perpendicular by welding
To in metallic rod 11, and insulating materials can be directly used and be made.
