Description

Technical Field

[0001] The invention belongs to the technical field related to copper electroplating, and more specifically, it is an anti-corrosion device for copper electroplating in electroplating line processing. Background Art

[0002] The anti-corrosion device for copper electroplating in electroplating line processing is a device used to perform anti-corrosion treatment on the copper plating layer on the surface of the electroplating line during the copper electroplating process of the electroplating line. By using it, a protective layer can be formed on the surface of the copper plating layer to prevent oxidation.

[0003] The patent document with the patent number CN112941513A discloses a production method of cyanide-free electroplated copper-clad aluminum wire, including the following steps: (1) alkaline washing and degreasing treatment; (2) first zinc immersion; (3) first zinc stripping; (4) second zinc immersion; (5) pre-copper plating; (6) main copper plating; (7) drying, drawing and collecting. In the method of the invention, the copper plating layer manufactured by the electroless plating solution has good adhesion to the metal material substrate, small porosity of the copper layer, smooth surface of the plating layer, and fine and bright crystals. When the electroless copper plating solution of the present application is used for electroless copper plating, a copper plating layer can be obtained quickly and stably, and the quality of the plating layer is good. The produced aluminum-copper alloy wire has a uniform thickness of the wire plating layer and stable wire quality. And the production efficiency is high and the defective rate is low.

[0004] During the copper electroplating process of the electroplating line, the copper plating layer on the surface of the electroplating line is prone to copper surface oxidation during the drying process. The conventional operation is to form an antioxidant layer on the surface of the copper plating layer by the immersion method or the spraying method. It cannot form multiple antioxidant layers on the surface of the copper plating layer of the electroplating line at one time, reducing the anti-corrosion effect on the surface of the electroplating line; at the same time, the traditional operation cannot complete the anti-corrosion processing of multiple groups of electroplating lines at one time, and it is easy to entangle between multiple electroplating lines, making it impossible for multiple electroplating lines to fully perform anti-corrosion operations, reducing the working efficiency during its anti-corrosion processing operation and having a single function; secondly, when the traditional method is used for the anti-corrosion immersion treatment of the electroplating line, affected by the immersion space and the length of the wire body, the electroplating line cannot fully absorb the antioxidant material while moving, reducing the anti-corrosion immersion effect of the copper plating layer of the electroplating line. Summary of the Invention

[0005] The purpose of the present invention is to provide an anti-corrosion device for copper electroplating in electroplating line processing, which can solve the existing problems.

[0006] The problems solved by the present invention are:

[0007] 1. During the copper plating process on the electroplating line, the copper plating layer on the surface of the electroplating line is prone to copper surface oxidation during the drying process. The conventional operation is to use the immersion method or spraying method to form an antioxidant layer on the copper plating layer surface, which cannot form multiple antioxidant layers on the copper plating layer surface of the electroplating line at one time, reducing the anti-corrosion effect on the surface of the electroplating line.

[0008] 2. At the same time, the traditional operation cannot complete the anti-corrosion processing operation of multiple groups of electroplating lines at one time, and it is easy to have winding phenomena between multiple electroplating lines, making it impossible for multiple electroplating lines to fully perform anti-corrosion operations, reducing the working efficiency during its anti-corrosion processing operation and having a single function.

[0009] 3. When the traditional method is used for anti-corrosion immersion treatment of the electroplating line, affected by the immersion space and the length of the wire body, the electroplating line cannot fully absorb the antioxidant material while moving, reducing the anti-corrosion immersion effect of the copper plating layer of the electroplating line.

[0010] The object of the present invention can be achieved by the following technical solutions:

[0011] An anti-corrosion device for electroplated copper in electroplating line processing, including a fixed base and a spraying box. The spraying box is fixedly installed in the middle position on the upper outer surface of the fixed base. One outer surface of the spraying box is fixedly installed with a drying box. On one side of the spraying box and the drying box on the upper outer surface of the fixed base, there are fixedly installed limiting brackets for fixing the wire body. Inside the fixed base, there is an immersion tank, and several groups of wire winding frames are fixedly installed on the inner side of the immersion tank. The several groups of wire winding frames are arranged side by side. Inside the spraying box, there is a spraying member for double-layer spraying on the wire body. The spraying member includes a lower pipe rack and an upper pipe rack. The lower pipe rack is fixedly installed below the upper pipe rack, and the lower pipe rack and the upper pipe rack are connected through a communicating pipe.

[0012] As a further technical solution of the present invention, the wire winding frame includes a first rolling rod and a second rolling rod. The first rolling rod is movably installed below the second rolling rod, and the first rolling rod and the second rolling rod are arranged side by side. When using this device, by pouring potassium dichromate liquid into the immersion tank of the fixed base, the copper plating layer on the surface of the metal wire is purified by using the potassium dichromate liquid. When in use, the user can pass the metal wire through the space between the first rolling rod and the second rolling rod of several groups of wire winding frames, so that the metal wire moves around the first rolling rod and the second rolling rod in an S shape, thereby increasing the time of the metal wire in the immersion tank. The S-shaped movement mode can effectively extend the immersion time of the metal wire, enabling the metal wire to perform long-term immersion operations without being affected by the space of the immersion tank, and improving the purification effect of the copper plating layer on the surface of the metal wire.

[0013] As a further technical solution of the present invention, fixed side plates are provided at both ends of the first rolling rod and the second rolling rod. The first rolling rod, the second rolling rod and the fixed side plates are all movably connected by rotating shafts. A clamping groove is provided on the side of the fixed side plate. The fixed side plate plays a role in connecting and fixing the installation between the first rolling rod, the second rolling rod and the fixed base. The fixed side plate enables the first rolling rod and the second rolling rod to maintain a reasonable distance, so that the metal wire can move in an S shape around the first rolling rod and the second rolling rod, increasing the length of the metal wire in the immersion tank.

[0014] As a further technical solution of the present invention, the limit clamping frame includes a lower pressing rod and an upper pressing rod. The lower pressing rod is arranged below the upper pressing rod. The lower pressing rod and the upper pressing rod are arranged side by side. There are several groups of arc-shaped grooves on the surfaces of the lower pressing rod and the upper pressing rod. Rolling shafts are arranged in the arc-shaped grooves. When the device performs anti-back-corrosion operations on several groups of metal wires at the same time, the lower pressing rod and the upper pressing rod can be used to assist in limiting several groups of metal wires, so that a reasonable distance is maintained between several groups of metal wires, enabling each metal wire to be fully subjected to anti-back-corrosion treatment. During operation, several groups of metal wires are simultaneously passed through between the lower pressing rod and the upper pressing rod. According to the thickness of the metal wire, the lower pressing rod and the upper pressing rod are moved to adjust the distance between the lower pressing rod and the upper pressing rod, so that several groups of metal wires are clamped in the arc-shaped grooves of the lower pressing rod and the upper pressing rod. The arc-shaped grooves are used to assist in positioning several groups of metal wires to prevent the metal wires from contacting and winding each other.

[0015] As a further technical solution of the present invention, a first support rod is movably installed on the outer surface of one end of the lower pressing rod and the upper pressing rod, and a second support rod is movably installed on the outer surface of the other end of the lower pressing rod and the upper pressing rod. The first support rod and the second support rod are arranged side by side, and sliding grooves are provided on the inner sides of the first support rod and the second support rod. Clamping bolts are sleeved on the middle parts of both ends of the lower pressing rod and the upper pressing rod. The sliding grooves can be used to adjust the distance between the lower pressing rod and the upper pressing rod between the first support rod and the second support rod. At the same time, by rotating the clamping bolts, the adjusted lower pressing rod and upper pressing rod are locked and fixed.

[0016] As a further technical solution of the present invention, several groups of upper spray heads are fixedly installed on the outer surface of the lower end of the upper pipe rack, and several groups of lower spray heads are fixedly installed on the outer surface of the upper end of the lower pipe rack. Several groups of upper spray heads and several groups of lower spray heads are all arranged side by side. The overall upper pipe rack and the lower pipe rack are both in a square structure. A feed pipe is provided at the feed end of the lower pipe rack. When several groups of electroplating wires are subjected to anti-back-corrosion operations, two limit clamping frames are used to make several groups of electroplating wires pass through the spraying box side by side. The antioxidant paint is poured into the upper pipe rack and the lower pipe rack through the feed pipe by the pump body. When the metal wire passes between the upper pipe rack and the lower pipe rack, the upper spray heads and the lower spray heads are used to perform two-way spraying operations on the metal wire, so that the antioxidant paint is evenly coated on the surface of the metal wire.

[0017] As a further technical solution of the present invention, fixed baffles are fixedly installed on the outer surfaces of both sides of the drying box, and a strip-shaped notch is provided in the middle position of the inner side of the fixed baffle. A hot air blower is fixedly installed on the outer surface of the upper end of the drying box, and an electric heating box is fixedly installed in the middle position of the inner side of the drying box. The hot air blower and the electric heating box are connected through a wind pipe. The metal wire coated with antioxidant paint moves through the strip-shaped notch of the fixed baffle by itself, so that the metal wire passes through the middle of the drying box, and the antioxidant paint on the surface of the metal wire is quickly cured by the cooperation of the electric heating box and the hot air blower.

[0018] As a further technical solution of the present invention, a first tank body and a second tank body are fixedly installed inside the fixed base. The first tank body and the second tank body are arranged side by side. A unwinding rack is provided on the outer surface of one end of the fixed base, a winding rack is provided on the outer surface of the other end of the fixed base, and a motor is provided at the end of the winding rack.

[0019] The beneficial effects of the present invention:

[0020] 1. By setting up a drying box and a spraying box, when using this anti-corrosion device for electroplated copper in an electroplating line, the user unwinds the metal wire using the unwinding rack, so that the wire body passes through the immersion tank of the fixed base. The first tank body fills the immersion tank with potassium dichromate liquid through a pipe body. The winding rack is used to pull one end of the metal wire for winding operation. The potassium dichromate liquid is used to purify the copper plating layer on the surface of the metal wire, so that an antioxidant layer is formed on the copper plating layer. When the metal wire moves, it enters the inside of the spraying box. The pump body fills the upper pipe rack and the lower pipe rack with antioxidant paint through the feed pipe. The metal wire passes between the upper pipe rack and the lower pipe rack. The upper pipe rack and the lower pipe rack can spray the metal wire bidirectionally from the upper and lower parts of the metal wire. When the metal wire passes between the upper pipe rack and the lower pipe rack, the upper nozzles and the lower nozzles installed on the upper pipe rack and the lower pipe rack are used to perform bidirectional spraying operations on the metal wire, so that the antioxidant paint is evenly coated on the surface of the metal wire, avoiding the phenomenon of spraying omission on the surface of the metal wire. At the same time, due to the movement of the metal wire, the metal wire sprayed with the second antioxidant layer will be transported to the inside of the drying box. The hot air blower and the electric heating box are connected through a wind pipe. The metal wire coated with antioxidant paint moves through the strip-shaped notch of the fixed baffle by itself, so that the metal wire passes through the middle of the drying box, and the antioxidant paint on the surface of the metal wire is quickly cured by the cooperation of the electric heating box and the hot air blower, so that the metal wire quickly completes the double-layer antioxidant layer, avoiding the phenomenon of back-corrosion of the copper plating layer on the surface of the metal wire. By cooperating the drying box and the spraying box with the immersion tank treatment, it can complete the double-layer electroplated copper anti-corrosion treatment operation by using the movement of the metal wire itself at one time.

[0021] 2. By setting two sets of limit brackets, when the copper electroplating anti-corrosion device for electroplating line processing is in use, multiple metal wires can be fixed simultaneously by the two sets of limit brackets, keeping a reasonable distance between the multiple metal wires to avoid entanglement during movement, improving the effect during immersion and spraying operations. During operation, the lower pressing rod and the upper pressing rod can be used to assist in limiting several groups of metal wires, keeping a reasonable distance between several groups of metal wires, so that each metal wire can be fully subjected to anti-corrosion treatment. Pass several groups of metal wires through between the lower pressing rod and the upper pressing rod. According to the thickness of the metal wire, move the lower pressing rod and the upper pressing rod to adjust the distance between the lower pressing rod and the upper pressing rod, so that several groups of metal wires are stuck in the arc-shaped grooves of the lower pressing rod and the upper pressing rod. The setting of the roller can reduce the friction when the metal wire moves. The arc-shaped grooves are used to assist in positioning between several groups of metal wires to avoid contact and entanglement between the metal wires. The sliding groove can be used to adjust the distance between the lower pressing rod and the upper pressing rod between the first support rod and the second support rod. At the same time, by rotating the fastening bolt, the adjusted lower pressing rod and upper pressing rod are locked and fixed, enabling the copper electroplating anti-corrosion device to complete the processing operation of multiple electroplating lines at one time and improving its working efficiency.

[0022] 3. By setting several groups of wire winding frames, when the copper electroplating anti-corrosion device for electroplating line processing is in use, install several groups of wire winding frames in the immersion tank of the fixed base. When soaking the metal wire, several groups of wire winding frames can make the metal wire move in an S shape, increasing the soaking time of the metal wire. Without reducing the moving speed of the metal wire, the soaking treatment effect is improved. During operation, the user can pass the metal wire through between the first roller and the second roller of several groups of wire winding frames, making the metal wire move around the first roller and the second roller in an S shape, thereby increasing the time of the metal wire in the immersion tank. The S-shaped movement mode can effectively extend the soaking time of the metal wire, enabling the metal wire to be soaked for a long time without being affected by the space of the immersion tank, improving the purification effect of the copper plating layer on the surface of the metal wire. The fixed side plate plays a role in connecting and fixing the installation between the first roller, the second roller and the fixed base. The fixed side plate keeps a reasonable distance between the first roller and the second roller, enabling the metal wire to move around the first roller and the second roller in an S shape, increasing the length of the metal wire in the immersion tank and improving the anti-corrosion soaking treatment effect.

The setting of the roller 26 can reduce the friction force when the metal wire moves, and the arc-shaped groove is used to assist in positioning between several groups of metal wires to avoid contact and entanglement between the metal wires. The sliding groove can be used to adjust the distance between the lower pressing rod 23 and the upper pressing rod 27 between the first support rod 22 and the second support rod 24.

When immersing the metal wire, several groups of wire winding frames 10 can make the metal wire move in an S shape, increasing the immersion time of the metal wire. Without reducing the moving speed of the metal wire, the immersion treatment effect is improved. During operation, the user can pass the metal wire through between the first roller 28 and the second roller 29 of several groups of wire winding frames 10. The S-shaped movement mode can effectively extend the immersion time of the metal wire, enabling the metal wire to be immersed for a long time without being affected by the space of the immersion tank, and improving the purification effect of the copper plating layer on the surface of the metal wire.
