Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of printed circuit board manufacturing field, especially a kind of accompanying plating edge material structure for vertical gantry plating line. BACKGROUND

[0002] In printed circuit board manufacturing, the printed circuit board needs to be electroplated, and the electroplating refers to a surface processing method in which the cations of pre-plating metal in a plating solution are deposited on the surface of a base metal to form a plating layer by electrolysis with the base metal as cathode in a salt solution containing the pre-plating metal. The commonly used electroplating production line is gantry electroplating production line, and the circuit board is positioned on a flying target by a clamp, and then the flying target is placed in an electroplating tank for electroplating operation.

[0003] In the existing electroplating process, because the sizes of PCBs are different, when the PCBs are sequentially clamped by clamps, the number of clamps cannot completely match the number of production line clamps, and several clamps are left unused. In order to avoid product warping and uneven copper plating, an accompanying plating edge strip is often clamped to improve the edge effect of electroplating. In the electroplating process of the equipment for the printed circuit board, the accompanying plating edge strip is plated with a layer of copper together with the PCB. Because the accompanying plating edge strip is recycled, the copper plated on the edge strip needs to be cleaned by chemical etching after the first plating of copper, and then the edge strip can be used again. This results in the waste of copper, although the amount of copper is small each time, but over a long period of time, it will also be a considerable cost for the enterprise. In addition, after the PCB is moved into the electroplating solution tank, it needs to be oscillated back and forth, so that the holes in the PCB can also be soaked in the solution. In this process, the accompanying plating edge strip and the PCB are separated, and the effect of accompanying plating is lost. SUMMARY

[0004] The utility model aims at providing an accompanying plating edge strip structure for vertical gantry electroplating line, which reduces the waste of copper, reduces the cost, improves the effect of accompanying plating, and reduces the edge effect through the improvement of the structure.

[0005] To achieve the above-mentioned purpose, the utility model adopts the technical scheme of an accompanying plating edge strip structure for vertical gantry electroplating line, which comprises a clamping part and a connecting part.

The adjacent PCB is inserted into the connecting groove to form the connection of the two. The clamping part and the connecting part are connected at the head and tail, and the clamping part is provided with a notch below.

[0006] In the above technical scheme, the clamping part and the connecting part are an integral structure, and the two are connected at the head and tail to form an inverted L-shaped structure.

[0007] In the above technical scheme, the groove bottom of the connecting groove is welded and fixed with the connecting part, the groove width is greater than 6.5MM, and the groove wall is loosely matched with the PCB.

[0008] In the technical scheme, the clamping part spans multiple clamps, and the length of the clamping part is adapted to the number of the remaining clamps; the length of the connecting part is adapted to the width of the PCB.

[0009] In the technical scheme, the total area of the clamping part and the connecting part is adapted to the copper plating thickness.

However, the utility model can be realized in many different forms and is not limited to the embodiments already described by means of the drawings. The embodiments described by reference to the drawings are exemplary and serve to make the disclosure of the utility model more thorough and comprehensive, but cannot be interpreted as limiting the utility model. In addition, if a detailed description of known technology is not necessary for the features of the utility model shown, these technical details can be omitted.

[0021] The following description is only the preferred embodiment of the utility model, and does not limit the scope of the utility model. In addition, the terms "vertical", "horizontal", "top", "bottom", "front", "back", "upper", "lower", "inner", "outer" and the like in the embodiments of the utility model indicate the orientation or positional relationship based on the drawings shown or the orientation or positional relationship of the product when it is usually placed, only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the utility model. The utility model will be described in detail below with reference to the drawings and in conjunction with the embodiments. Figure 1

[0022] Referring to Figures 1 to 3 As shown in the drawings, a vertical gantry electroplating line with an accompanying plating edge strip structure includes a clamping part 1 and a connecting part 2, the clamping part 1 is used for hanging clamps 3, the connecting part 2 is provided with a connecting groove 5 corresponding to one side of a PCB 4, adjacent PCBs 4 are inserted into the connecting groove 5 to form a connection between them; the clamping part 1 and the connecting part 2 are connected end to end, and the clamping part 1 is provided with a notch 6 below.

[0023] In this embodiment, the clamping part 1 and the connecting part 2 are an integral structure, and are connected end to end to form an inverted L shape. Among them, the clamping part 1 spans multiple clamps 3, and its length is adapted to the number of remaining clamps; the length of the connecting part 2 is adapted to the width of the PCB 4. Here, because the processed PCB 4 has multiple models corresponding to different widths, after being arranged in sequence, there are remaining empty clamps 3, and the empty clamps will also be soaked in the solution, thereby forming copper liquid dripping, polluting the inside of the equipment, so the clamping part 1 is used to fill the remaining clamps.

[0024] In another embodiment, if the width of the clamping part 1 is not enough to fill the remaining clamps, it also includes a supplementary empty material 7, which is arranged on the side of the clamping part 1 to fill the remaining empty clamps. As Figure 1 shown.

[0025] ​The adapter 2 is adapted to the width of the side PCB board 4, and can also exceed the width of the PCB board 4, and is based on the maximum width of the PCB board 4 to meet the use of various types of boards.

[0026] As shown in Figure 3 The bottom of the connecting groove 5 is welded and fixed with the adapter 2, the groove width is greater than 6.5MM, and the groove wall 8 is loosely matched with the PCB board 4. The width of the connecting groove 5 is adapted to the thickness of the PCB board 4, and is slightly larger than the thickness of the PCB board 4. In the prior art, the maximum thickness of the PCB board 4 is 6.4MM, and "adapted" means that the maximum size of the PCB board 4 can be inserted into the connecting groove 5. Since the PCB board 4 swings forward and backward during soaking in the solution, the groove width of the connecting groove 5 is slightly larger than the thickness of the PCB board 4, and the consistent movement of the two will not be affected, and various specifications and types of PCB boards 4 can be used.

[0027] The total area of the clamping part 1 and the adapter 2 is adapted to the copper plating thickness. According to the principle of electroplating, the current is conducted to the PCB board 4 and the accompanying plated edge material through the clamp 3, and reacts with the soaked medicine water. Under the condition that the current value is equal, the size of the conductor determines the thickness of the copper plating. Here, "adapted" means the minimum area of the accompanying plated edge material under the condition of ensuring the thickness of the copper plating on the edge of the PCB board, and a balance point is sought (a person skilled in the art can calculate the calculation model according to the actual size of the PCB board to be processed and the rated current of the clamp).

[0028] The above only describes some embodiments of the present application. It should be noted that for those skilled in the art, without departing from the principles of the present application, some improvements and refinements can be made, and these improvements and refinements should also be considered as the protection scope of the present application.
