Embodiment
Below embodiment of the present utility model is described in detail:
As shown in Figure 1, a kind of copper block oxide frock clamp, at least one framework 300 comprising base plate 200 and be connected with base plate 200, framework 300 coordinates the container cavity 310 forming accommodating copper billet 100 with base plate 200.At least at least large than the thickness of copper billet 100 0.2mm of the degree of depth of framework 300, prevents copper billet 100 upper surface and cover plate 400 from fitting, causes copper billet 100 upper surface brown bad.The size of container cavity 310 can according to actual treat brown copper billet 100 be dimensioned to different specifications, to adapt to the copper billet 100 brown demand of different size.Base plate 200 offers multiple first through holes 210 be communicated with container cavity 310, is convenient to brown liquid medicine and exchanges.As shown in Figure 2, the sidewall of container cavity 310 is arranged with at least one groove 311, prevents the sidewall close contact of the sidewall of copper billet 100 and container cavity 310 from causing the sidewall brown of copper billet 100 bad.Frock clamp of the present utility model can cross horizontal brown line by normal pcb board brown mode, and can not make generation harmful effect to other pcb board brown.It can realize, and the brown of copper billet 100, baking and other subsequent treatment are unified to be used, and needs copper billet 100 to take out, cause the surperficial brown film of copper billet 100 easily to wipe flower after avoiding traditional brown process.And frock clamp can unlimitedly use without under damaged condition, easy to operate and durability good.
As shown in Figure 2, in the present embodiment, base plate 200 offers second through hole 220, second through hole 220 relative with groove 311 and is communicated with groove 311.Brown liquid medicine can enter groove 311 from the second through hole 220, has more liquid medicine and copper billet 100 sidewall contact when guaranteeing copper billet 100 sidewall and container cavity 310 sidewall contact, ensures copper billet 100 fully brown.Groove 311 is multiple, and multiple grooves 311 are evenly arranged in the sidewall of container cavity 310.The utility model can be holed to framework 300 and base plate 200, and obtain integrated above-mentioned groove 311 and the second through hole 220, the course of processing is simple.
As shown in figures 1 and 3, the utility model also comprises cover plate 400, and framework 300 removably connects away from one end of base plate 200 and cover plate 400, when copper billet 100 brown time, cover cover plate 400, ensure that copper billet 100 can not be lost in brown process, be conducive to the volume production of copper billet 100.Cover plate 400 offers the third through-hole 410 be communicated with container cavity 310, be convenient to liquid medicine and exchange.
As shown in Figure 3, framework 300 and cover plate 400 are removably connected by connector 500, and cover plate 400 and framework 300 are equipped with the fixing hole 320 coordinated with connector 500.In the present embodiment, connector 500 is pin, and the utility model also can select other connectors 500 such as screw, rivet according to actual needs.
Base plate 200, framework 300, cover plate 400 are the FR4 sheet material making the common high Tg that pcb board is commonly used, and draw materials easily, easy to make, durability is good, significantly reduces production cost.Base plate 200 need possess certain rigidity and be used for supporting and placing copper billet 100, and its thickness is 0.5mm.Cover plate 400 also needs to possess certain rigidity, protection copper billet 100 in brown process not by roller extruding, liquid medicine impact, wind pressure etc. act on cause that brown is bad, loss etc., its thickness is 0.5mm.
Base plate 200 and framework 300 can be integrated formed structure, and obtain container cavity 310 by controlling dark groove milling on FR4 sheet material, moulding process is simple, and cost of manufacture is lower.Fixture overall dimensions is 18 × 24inch, is conventional pcb board processing dimension, matches with production technology, convenient processing.
As shown in Figure 4, framework 300 is multiple, forms multiple framework 300 be set up in parallel by controlling dark groove milling on FR4 plate.In each framework 300 limit put a copper billet 100, frock clamp once can the multiple copper billet 100 of brown, both improve the load capacity of brown process, improve efficiency, the brown quality of copper billet 100 can have been ensured again.Spacing between adjacent two frameworks 300 is 8-10mm, avoids the spacing of adjacent frame 300 too short, makes fixture in use be subject to the effect such as ambient pressure, collision and the connecting plate between adjacent frame 300 is ruptured, damage fixture.
Also for ease of and ensure rigidity of the present utility model, multiple first through hole 210 is evenly arranged in base plate 200, as shown in Figure 4.Multiple third through-hole 410 is evenly arranged in cover plate 400, as shown in Figure 3.Spacing between adjacent two the first through holes 210 and the spacing between adjacent two third through-holes 410 are 2-4mm.Prevent the rigidity of the less reduction fixture of spacing between through hole.It also avoid spacing between through hole causes more greatly the number of openings of corresponding container cavity 310 to reduce simultaneously, is unfavorable for that liquid medicine exchanges, and causes copper billet 100 cannot abundant brown.
As shown in Figure 4, in the present embodiment, multiple first through hole 210 is circular port.The large I of circular port determines according to the size of actual copper billet 100, ensures that copper billet 100 can not drop from circular port.Because general its shape of copper billet 100 is square or rhombus, through hole of the present utility model is preferably circular port, can prevent copper billet 100 that is square or rhombus from dropping from the first through hole 210.When the diameter of circular port is 2mm, the utility model can realize the surperficial brown process of minimum 3mm × 3mm copper billet 100.
To sum up, the utility model can adapt to the brown process of the copper billet 100 of different size, easy to operate, has larger practicality.It with multiple framework 300 by design, is improve the load capacity of brown process, improves efficiency.Framework 300 inside is designed by special groove 311, ensures the normal brown of copper billet 100, improves copper billet 100 brown quality.And the utility model can unlimitedly use without under damaged condition, easy to operate and durability good, significantly reduce brown process costs.
Each technical characteristic of the above embodiment can combine arbitrarily, for making description succinct, the all possible combination of each technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics does not exist contradiction, be all considered to be the scope that this specification is recorded.
The above embodiment only have expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
