The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1 to 4, a method for using an anti-corrosion collector bar, the anti-corrosion collector bar comprising: titanium material barred body 1, titanium material barred body 1 include first link 11 and second link 12. Copper material barred body 2, copper material barred body 2 include third link 21 and fourth link 22, and third link 21 can be dismantled with second link 12 and be connected, or fourth link 22 can be dismantled with second link 12 and be connected. That is to say, arbitrary one end of copper product barred body 2 all can dismantle with titanium material barred body 1 and be connected, can improve the convenience and the interchangeability of installation like this, and the staff can select arbitrary one end to be connected with titanium material barred body 1 when the installation, can improve the installation effectiveness. In this embodiment, the conductive rod is used to increase the conductive effect, so that the plated layer can be more uniform, and the conductive rod itself is not used as an anode.
The use method of the anti-corrosion conductive rod comprises the following steps:
s1: the second connecting end 12 of the titanium rod body 1 is connected with the third connecting end 21 of the copper rod body 2 to form the anti-corrosion conducting rod, or the second connecting end 12 of the titanium rod body 1 is connected with the fourth connecting end 22 of the copper rod body 2 to form the anti-corrosion conducting rod.
S2: the first connecting end 11 of the titanium rod 1 is immersed into the electroplating solution in the electroplating bath, at the moment, the copper rod 2 is kept dry, the third connecting end 21 or the fourth connecting end 22 of the copper rod 2 is connected with a direct current power supply, and the titanium rod 1 leads current to the electroplating solution.
In this embodiment, the titanium rod may be partially immersed in the plating solution or completely immersed in the plating solution, and may be set according to the requirements of the actual plating process. The copper rod 2 can be connected with the positive pole of a direct current power supply, and current enters the electroplating solution through the copper rod and the titanium rod, so that metal ions in the electroplating solution move to the surface of a product to be plated under the action of potential difference to form a plating layer. In the embodiment, the anti-corrosion conductive rod only plays the roles of transmitting electrons and conducting current, and can enhance the moving speed of metal ions in the electroplating solution, so that the plating layer is deposited on the surface of a product more uniformly. Since the thickness of the metal plating layer deposited on the film surface of the COF product is in the micron order, the unsatisfactory thickness and uniformity of the plating layer can seriously affect the use of the product, for example, when the COF product is applied to a display screen, the conductivity and the signal transmission effect are affected.
In this embodiment, the end surface of the second connection end 12 is provided with the threaded post 13, the end surface of the third connection end 21 is provided with the second mounting hole 23, and the end surface of the fourth connection end 22 is provided with the third mounting hole 24. When the third connecting end 21 is detachably connected with the second connecting end 12, the threaded column 13 is in threaded connection with the second mounting hole 23, so that the end face of the second connecting end 12 is tightly attached to the end face of the third connecting end 21. When the fourth connection end 22 is detachably connected to the second connection end 12, the threaded post 13 is in threaded connection with the third mounting hole 24, so that the end face of the second connection end 12 is tightly attached to the end face of the fourth connection end 22. The end face of the titanium rod body 1 is tightly attached to the end face of the copper rod body 2, so that the electric conductivity is improved.
In this embodiment, the titanium rod 1 has two first planar surfaces 14 on the periphery near the second connecting end 12, and the two first planar surfaces 14 are symmetrically arranged. The periphery of the copper rod body 2 close to the third connecting end 21 is provided with two second flat tangent planes 25, and the two second flat tangent planes 25 are symmetrically arranged; the copper bar body 2 is provided with two third flat section 26 at the periphery near the fourth connecting end 22, and the two third flat sections 26 are symmetrically arranged. When the titanium material rod body 1 and the copper material rod body 2 are connected, the first flat section 14, the second flat section 25 and the third flat section 26 can enable the titanium material rod body 1 and the copper material rod body 2 to be connected more tightly, for example, when a wrench is used for connecting the threaded column 13 and the second mounting hole 23, the first flat section 14 and the second flat section 25 can increase the contact area of the wrench and the rod body, so that the threaded column 13 and the second mounting hole 23 are connected more firmly in a threaded manner.
In this embodiment, the outer diameter of the titanium rod 1 is d1, the outer diameter of the copper rod 2 is d2, and the outer diameter d1= d 2. In this embodiment, the titanium rod 1 and the copper rod 2 are preferably cylindrical, and the outer diameter d1= d2 enables the conductive effect to be better.
In this embodiment, the end surface of the first connection end 11 is provided with a first mounting hole 15, and when the corrosion-proof conducting rod comprises a plurality of titanium rod bodies 1, the first mounting hole 15 can be in threaded connection with the threaded column 13 of another titanium rod body 1. That is to say, when the plating solution capacity is more, and the plating bath degree of depth is darker, can splice a plurality of titanium material barred bodies 1 to satisfy the user demand, can improve the convenience and the saving cost that the conducting rod used.
In this example, the length of the titanium rod 1 was 140cm, and the length of the copper rod 2 was 100 cm. The length of the titanium rod 1 and the length of the copper rod 2 can be designed according to the depth of the plating bath and the depth of the plating solution.
In this embodiment, the end surface of the first connection end 11 is perpendicular to the axis of the titanium rod 1. The titanium material has good corrosion resistance, is not easy to corrode when immersed in electroplating solution, and the end face of the first connecting end 11 is perpendicular to the axis of the titanium material rod body 1, so that the phenomenon of point discharge can be avoided, and the service life of the conducting rod is prolonged.
As described above, in the method of using the corrosion-resistant conductive rod of the present invention, the titanium rod 1 and the copper rod 2 are joined together, and the corrosion-resistant titanium rod 1 is immersed in the plating solution, whereby the copper rod 2 is kept dry in the air. On one hand, the service life of the conductive rod can be prolonged, the phenomenon of point discharge is avoided, the thickness and uniformity of a product coating can meet the standard, and the yield of the product is improved; on the other hand, the frequency of replacing the conductive rod by workers can be reduced (for example, the conductive rod made of pure copper needs to be replaced in sequence in a week, the service life of the anti-corrosion conductive rod can be as long as one year), the working efficiency and the production efficiency are improved (for example, for a single-row electroplating line which can produce 5040 meters in a week, the replacement of the conductive rod made of pure copper needs to take 3 hours once, but the anti-corrosion conductive rod does not need to be replaced in a year), even if the titanium rod body 1 reaches the service life, only the titanium rod body 1 needs to be replaced, and the copper rod body 2 can be continuously used, so that the use cost of the conductive rod can be reduced.
In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the contents of the specification, and must be determined by the scope of the claims.
