Description

Improved structure of anode device

technical field

The utility model relates to an improved structure of an anode device, in particular, it is suitable for electroplating treatment of printed circuit boards or other plate-shaped industrial products, and can prevent the electroplating solution from being blocked by the anode plate too much, resulting in low electroplating solution smoothness of flow.

Background technique

It is well known that printed circuit boards must be electroplated during the manufacturing process, and other plate-shaped industrial products also have the opportunity to be electroplated; the known electroplating treatment method is to set conveying rollers in the electroplating tank, and the conveying rollers are immersed in the electroplating tank Below the liquid level of the electroplating solution inside, there is a tube body and an anode device between the rollers. The inlet and outlet directions of the electroplating tank are respectively equipped with cathode rollers. The printed circuit board is composed of the cathode roller and the conveying roller to contact the printed circuit. When the printed circuit board is conveyed through the anode device and the tube body, the electroplating solution gushed out of the tube body can make the metal ions in the electroplating solution positively charged after passing through the anode device, and flow through the printed circuit board. The surface of the board and the holes allow the positively charged metal ions to attach to the negatively charged printed circuit board to achieve electroplating.

Because the traditional anode plate A is a whole piece of fine metal mesh (as shown in Figure 5), the electroplating solution flowing out from the liquid injection port of the infusion tube will be dispersed when passing through the anode plate, which directly affects the flow of the electroplating solution. smoothness, so the utility model is to improve the above-mentioned defects in the traditional electroplating anode device.

Detailed ways

As shown in Figure 1, the improved structure of the anode device provided by the utility model includes upper and lower fixing seats 1, 1A and two groups of infusion tubes 3 respectively arranged on the upper and lower sides, and two groups are used to assemble on the upper and lower The anode plate 2 in the inner space of the lower fixing seat 1, 1A.

The structures of the upper and lower fixing bases 1 and 1A are the same, and the structure of the upper fixing base 1 is now used for illustration, which is also applicable to the lower fixing base 1A. As shown in Figure 1, a narrow water inlet 111 and a wide water outlet 14 in the shape of a continuous groove are respectively provided on opposite sides of the upper fixing seat 1, so that the end of the upper fixing seat 1 has a ladder shape. shape; again, the two side ends of the upper fixing seat 1 are formed into a through shape, and the water outlet 14 is integrally provided with a plurality of ribs 13 arranged obliquely and obliquely, so that the water outlet 14 is also arranged obliquely. By means of these ribs 13 The strength of the water outlet 14 can be reinforced. The arrangement and combination of the plurality of ribs 13 is that the upper fixing seat 1 is formed to be divided into two areas by the center, and the ribs 13 in the two areas are symmetrical to each other to form a herringbone water outlet 14, by being arranged obliquely The water outlet 14 can make the thin printed circuit board pass through without corner interference and clamping board; in addition, the inner opposite side walls of the upper fixing base 1 are respectively provided with corresponding rail grooves 12 near the water inlet 111. .

The preferred embodiment of the upper and lower fixing bases 1, 1A is integrally formed and reassembled to be located on the upper and lower sides respectively, and make the water outlets 14 correspond to each other and maintain a space for the printed circuit board to pass through. Described anode plate 2 is a strip net plate shape, and its plate body offers an elongated groove 21 (as shown in Figure 3); In order to avoid the anode plate 2 because being subjected to the influence of offering groove 21 and reducing intensity and To produce deflection and deformation, the utility model additionally provides a skeleton 22 to combine with the anode plate 2. The skeleton 22 has two parallel and conductive rods 221, and the anode plate 2 is fixed to the two poles by spot welding. 221, and the groove 21 is located between the two rods 221, and this design can also make the conductive distribution of the anode plate 2 more uniform when the current is passed through the skeleton 22 to the rods 221. , so as to avoid the resistance of the anode plate 2 being too large, thus solving the situation of uneven current distribution.

The lower side of the infusion tube 3 of the utility model is provided with a long groove-shaped liquid spray port 32 , and two opposite outer sides of the liquid spray port 32 are respectively provided with a rail bar 31 .

The combination of the aforementioned components is to put the combined anode plate 2 and skeleton 22 directly into the inner space 11 of the upper and lower fixing bases 1 and 1A, and then place the rails 31 of the infusion tube 3 along the upper and lower The rail grooves 12 of the fixing base 1, 1A slide in to combine the upper and lower fixing bases 1, 1A and the two infusion tubes 3, and finally the first base body 41, the second base body 43 and the pads 42, 44 The formed end fixing part 4 is combined with the ends of the upper and lower fixing seats 1, 1A and the infusion tube 3 to prevent the frame 22 and the infusion tube 3 from detaching from the upper and lower fixing seats 1, 1A. Because the circuit board is covered with many through-holes, in order to avoid the liquid flow in the through-holes offsetting each other because the upper and lower liquid jets are facing each other, although the upper and lower liquid jets are facing downward and upward respectively, but the upper and lower liquid jets are not corresponding to each other on a straight line and are staggered (as shown in Figure 4), and the anode plates 2 arranged on the upper and lower The grooves are also respectively staggered to correspond to the upper and lower liquid injection ports. Described upper and lower fixing seats 1, 1A are connected in series and can be installed in the electroplating tank 5 (as shown in Figure 2 ) after being combined into one group. After the liquid spray port 32 flows out, it can flow out again through the groove 21 of the anode plate 2, so that the flow of the electroplating solution is smoother than the conventional one.
