Abstract

An electroplating clamping apparatus for an PC board, which is mainly provided with two clips, wherein one clip is provided with a symmetrical lug in the middle, while the other clip is provided with a relief pivoted part in the middle, so that the two clips can sway by the connection of the lug and the pivoted part, wherein, the clip that provided with the pivoted part is arranged with a bolt on the top direction, and a spring connects one top end of the clip with the other top end of the clip, so the two clips can support the top through the spinning of the bolt, then the bottom of the clip can soak the clamp PC board in the electroplating liquid medicine, and the PC board can be spun out of the bolt after electroplating, because the bolt is higher than the liquid surface, it will not be plated with different metals to reduce the nitric acid consumption and environmental pollution, and avoid electric current loss in the electroplating process.

Description

A kind of PC plate electroplating clamp

Technical field

The utility model relates to PC plate field of electroplating, particularly relates to a kind of reusablely and needn't clean holding bolt with nitric acid liquid, and the holding bolt current sinking causes current loss when preventing to electroplate, to improve the anchor clamps of electroplating quality.

Background technology

Generally be used for PC plate electroplating jig as shown in Figure 1: a bolt 11 is installed, the PC plate is fixed between clamp 1 and the bolt 11 on clamp 1.Bolt 11 is with in the PC plate 20 immersion plating solution 6 during plating.There is following defective in this anchor clamps:

Can plate different metal with the PC plate during 1, owing to bolt 11 each plating, therefore must clean up with nitric acid liquid before the use next time.And nitric acid is the high pollution chemical article, and consumption is crossed senior general and caused environmental pollution.

2, as cleaning electrolytic coating on the bolt, because of spiral shell button tension, make the rotation difficulty when reusing without nitric acid.

After being immersed in nitric acid liquid when 3, bolt 11 is grown, will cause shorten work-ing life, and need after for some time to upgrade, increase production cost.

4, in the electroplating process, conduct electricity, cause current loss and reduce electroplating quality owing to bolt 11 is outstanding.

The utility model content

The purpose of this utility model provides a kind of simple in structure, avoids the novel PC plate electroplating clamp in the holding bolt immersion plating solution.

For achieving the above object, the utility model is taked following technical scheme: a kind of PC plate electroplating clamp, and it includes: a kind of PC plate electroplating clamp is characterized in that it includes:

First clamp, its bottom are the hook shape, and the top is provided with the screw that two levels wear, and the top is provided with fixed orifices, and are provided with symmetric lug in middle position;

Second clamp, its bottom are the hook shape, and middle position is provided with the floating prominent articulated section corresponding to the first clamp lug, and the top is provided with a bolt, and is provided with fixed orifices in the top;

This second clamp is placed on the lug of first clamp with its articulated section and fixes with gim peg, and the swing of two clamps connects, and connects spring formation electroplating clamp in the fixed orifices of two clamps.The PC plate holder is placed the bending hook part of two clamp bottoms, bolt is screwed in make the PC plate fixing again, make anchor clamps exempt the trouble of cleaning, and prevent that current loss is to improve electroplating quality with natal etch because of bolt is higher than the liquid medicine liquid level for immersion plating liquid medicine.

The utility model has adopted the scheme that directly tightens up the PC plate without bolt, but utilizes lever principle, and the power that will tighten up passes to the PC plate by clamp, thereby avoided bolt to contact with the direct of PC plate, has realized the purpose that bolt needn't immersion plating solution.

Embodiment

As shown in Figures 2 and 3, be a kind of PC plate electroplating clamp provided by the utility model, it includes:

First clamp 2 and second clamp 3, wherein first clamp, 2 bottoms are for colluding shape, the screw 21 and 22 that the top has two levels to wear, there is a fixed orifices 23 on the top, and there are two lugs 24,25 in central authorities; Second clamp, 3 bottoms are for colluding shape, and middle position is provided with the floating prominent articulated section 31 corresponding to first clamp, 2 lugs 24,25, and the top then is provided with a bolt 33 with lever 32, and establish with fixed orifices 34 in the top;

This second clamp 3 is placed on the lug 24 of the first clamp 2d with its articulated section 31, after 25, fixing with gim peg 4, make first, second clamp 2,3 are a spot wobble with gim peg 4, and in first, second clamp 2,3 vertical fixed orificess 23,34 connect a spring 5, to constitute anchor clamps, the PC plate holder is placed first, second clamp 2,3 the bottom bending hook part, again bolt 33 is screwed in and be attached on first clamp 2, make the PC plate holder be fixed in anchor clamps, be soaked in electroplate liquid for the PC plate, and because of being higher than the liquid medicine liquid level, bolt can not plate different metal in the electroplating process, the trouble that release is cleaned with natal etch, reduce environmental pollution, and the suction electric current causes current loss in preventing to electroplate, and then improve electroplating quality.

Please consult Fig. 4 simultaneously, Fig. 5, when the utility model uses, PC plate 20 is folded in first of anchor clamps, second clamp 2,3 bottoms, bolt 33 being screwed in makes it be attached on first clamp 2 with PC plate 20 tight clampings again, with anchor clamps immersion plating liquid medicine 6, carry out the electroplating activity of PC plate 20, because wherein bolt 33 is higher than liquid medicine 6 liquid levels, therefore can not be coated with different metal, when recycling once more, do not need to clean with the nitric acid liquid etch, make electroplating activity more convenient, and, can reduce environmental pollution because of reducing the consumption of nitric acid liquid, moreover, because bolt 33 is higher than liquid medicine 6 liquid levels, first, second clamp 2, therefore the neither projection that exists in 3 bottoms can not suck the loss that electric current causes electric current, and then raising electroplating quality, and when electroplate finish after, bolt 33 is screwed out, make first by the pulling force of spring 5, second clamp 2,3 open, and with screw 21,22 location are for taking out PC plate 20.

In sum, the utility model has adopted and has utilized lever principle, directly tighten up the scheme of PC plate without bolt, the power that will tighten up passes to the PC plate by clamp, bolt is not directly contacted with the PC plate, avoid bolt immersion plating solution, realized the purpose that to clean bolt, minimizing bolt current loss with nitric acid, improve electroplating quality.
