Description

Technical Field

[0001] The present invention relates to the technical field of conductive conveying, and particularly relates to a conductive mechanism and a workpiece processing system. Background Art

[0002] Electroplating refers to the electrolytic reaction in a solution with the help of an external direct current, so as to deposit a metal or alloy layer on the surface of a conductor. When electroplating, the anode of the electrode is electrically connected to the electroplating solution, and the cathode of the electrode is connected to the work piece with conductivity. When the current is switched on, the positively charged cations in the solution swim towards the cathode of the circuit, are reduced on the surface of the work piece, and form an electroplating layer covering the surface of the work piece.

[0003] In an electroplating system, one end of a hanger clamps the work piece to be processed, and the other end of the hanger needs to be electrically connected to a conductive component to transfer the external cathode electricity to the work piece to be processed, so that the work piece to be processed is electrified. In the prior art, the top of the hanger is fixed on a conveying mechanism and moves along with the movement of the conveying mechanism. The conductive components are several and are arranged in sequence along the moving direction of the hanger. When the hanger moves along with the conveying mechanism, one side wall of the hanger slidably frictionally abuts against the conductive component, so that the hanger transfers the electricity of the external power supply to the hanger, and then the hanger transfers it to the work piece to be processed fixed at the bottom of the hanger.

[0004] However, since there is always a sliding friction force between one side wall of the hanger and the conductive component, due to the existence of this friction force, when the hanger continuously slides relative to the conductive component for a period of time, both the one side wall of the hanger and the conductive component will be worn to a certain extent, resulting in poor contact between the hanger and the conductive component, affecting the conductivity between the conductive component and the hanger, and even unable to continuously conduct electricity to the work piece to be processed. At the same time, due to the long-term friction between the conductive component and one side wall of the hanger, inevitably, the surface material of the electrical component or the hanger is worn and falls off, and will fall into the solution tank below the hanger, polluting the bath solution in the electroplating tank and resulting in poor electroplating effect. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defects that after long-term wear between the conductive component and the hanger in the prior art, the contact between the two is poor, the conductivity between the conductive component and the hanger is poor, and the work piece to be processed cannot be continuously conducted electricity; and the surface materials of the conductive component and the hanger are worn and fall into the solution tank, affecting the electroplating effect, so as to provide a conductive mechanism and a workpiece processing system.

[0006] A conductive mechanism includes: a seat body having a receiving cavity for accommodating a conductive working medium for lubrication; at least one conductive component disposed in the receiving cavity, each conductive component having a conductive surface; a hanger slidably disposed relative to the seat body; the hanger having a body outside the seat body and an extension provided at one end of the body facing the conductive surface; the extension extends into the receiving cavity, and when sliding, the outer sidewall of the extension can slidably abut against the conductive surface of any one of the conductive components.

[0007] Optionally, in the above conductive mechanism, the seat body includes a groove with an open top, and the inner cavity of the groove serves as the receiving cavity;

[0008] The extension passes over a groove wall of the groove and is embedded into the receiving cavity through the notch of the groove, so as to slidably abut against the conductive surface of any one of the conductive components when sliding.

[0009] Optionally, in the above conductive mechanism, the extension is in the shape of a plate, and a surface abutment is formed between the conductive component and the conductive surface.

[0010] Optionally, in the above conductive mechanism, both ends of the groove are open in the sliding direction of the hanger for the conductive working medium to flow from one open end to another open end in the groove.

[0011] Optionally, in the above conductive mechanism, a supply mechanism is further included for supplying the conductive working medium into the groove;

[0012] A reflux groove, both ends of which are respectively connected to the inner cavity of the groove through pipelines; and

[0013] A filter provided on the pipeline between the reflux groove and the groove.

[0014] Optionally, in the above conductive mechanism, a biasing component connected to the conductive component is further included; [[ID=2I5]]

[0015] The conductive component is subjected to a biasing force exerted by the biasing component, so that the conductive surface tends to slidably abut against a sidewall of the extension.

[0016] Optionally, in the above conductive mechanism, there are several conductive components, and all the conductive components are arranged and distributed in sequence along the sliding direction of the hanger.

[0017] Optionally, in the above conductive mechanism, the body is in a frame shape.

[0018] Optionally, in the above conductive mechanism, the conductive component is a conductive brush.

[0019] A workpiece processing system includes:

[0020] At least two sequentially arranged troughs, which are connected between adjacent troughs; the top of any one of the troughs has a top opening;

[0021] The conductive mechanism as described above; the hanger of the conductive mechanism is used to drive the workpiece to be processed to slide in any one of the troughs.

[0022] The technical solution of the present invention has the following advantages:

[0023] 1. A conductive mechanism provided by the present invention includes: a seat body, which has a receiving cavity, and the receiving cavity can be used to accommodate a conductive working medium for lubrication; at least one conductive component, which is arranged in the receiving cavity, and each conductive component has a conductive surface; a hanger, which is slidably arranged relative to the seat body; the hanger has a body located outside the seat body, and an extension part provided at one end of the body facing the conductive surface; the extension part extends into the receiving cavity, and when it slides, the outer side wall of the extension part can slidably abut against the conductive surface of any one of the conductive components.

[0024] In the conductive mechanism of this structure, by setting the seat body, arranging the conductive components in the receiving cavity of the seat body, the hanger can be slidably arranged relative to the seat body, and the extension part of the hanger can slidably abut against the conductive surface after extending into the receiving cavity. A conductive working medium for lubrication is accommodated in the receiving cavity. When the extension part and the conductive surface slide relative to each other, the extension part and the conductive components are immersed in the conductive working medium. This conductive working medium can play a lubricating role, effectively reducing the friction force between the conductive components and the extension part, and further greatly reducing the wear amount between the conductive components and the hanger, avoiding the situation of poor contact between the two, and being able to continuously supply power to the workpiece to be processed; at the same time, the surface materials of the conductive components and the hanger are directly mixed into the conductive working medium after being worn, and will not fall into the solution tank again, thus being able to avoid the situation of the plating solution being contaminated by the worn and fallen materials; the conductive working medium can also cool the conductive components, avoiding the problem that the conductive components have too high temperature due to frictional heat generation, which in turn affects the conductivity of the conductive components, and ensuring the uniform distribution of electricity conduction for the workpiece to be processed.

In a conductive mechanism provided by the present invention, it further includes a supply mechanism for supplying a conductive working medium to the groove; a return tank, the two ends of which are respectively connected to the inner cavity of the groove through pipelines; and a filter provided on the pipeline between the return tank and the groove.

The setting of the return groove enables the conductive working medium in the groove to flow reciprocally, making multiple uses of the conductive working medium. The setting of the filter can filter the materials in the conductive working medium that has been used multiple times, ensuring the purity of the conductive working medium entering the groove.

[0037] Embodiment 1

[0038] This embodiment records a conductive mechanism. Refer to Figure 1 and Figure 2 . The conductive mechanism includes a seat body 1, a conductive component 2, and a hanger 3. The seat body 1 has a receiving cavity 11 for accommodating a conductive working medium for lubrication. The conductive component 2 is arranged in the receiving cavity 11, and the conductive component 2 has a conductive surface 21. The hanger 3 can be slidably arranged relative to the seat body 1. When the hanger 3 slides relative to the seat body 1, the hanger 3 can contact the conductive surface 21. The number of conductive components 2 is set to at least one, and can be multiple. The specific number is set according to specific actual needs. In specific applications, the conductive component 2 can be set as a block-shaped conductive brush 22, and the material of the conductive brush 22 is copper. A plurality of conductive components 2 are located in the receiving cavity 11, and all the conductive components 2 can be arranged and distributed in sequence along the sliding direction of the hanger 3 in the receiving cavity 11.

[0039] Specifically, the hanger 3 has a body 31 located outside the above-mentioned seat body 1 and an extension part 32 provided at one end of the body 31 facing the conductive surface 21. The body 31 is in a frame shape. The extension part 32 can extend into the receiving cavity 11 of the seat body 1. When the body 31 of the hanger 3 slides relative to the seat body 1, the outer side wall of the extension part 32 can slidably abut against the conductive surface 21 of any one of the conductive components 2 to conduct electricity to the hanger 3 through the conductive component 2.

[0040] By providing the base body 1, the conductive component 2 is arranged in the accommodation cavity 11 of the base body 1. The hanger 3 can be arranged to slide relative to the base body 1. After the extension part 32 of the hanger 3 extends into the accommodation cavity 11, it can be in sliding contact with the conductive surface 21. The conductive working medium for lubrication is accommodated in the accommodation cavity 11. When the extension part 32 and the conductive surface 21 are in relative sliding movement, the extension part 32 and the conductive component 2 are immersed in the conductive working medium. This conductive working medium can play a lubricating role, effectively reducing the frictional force between the conductive component 2 and the extension part 32. Furthermore, the wear amount between the conductive component 2 and the hanger 3 can be greatly reduced, achieving the effect of stable conduction between the conductive component 2 and the extension part 32, avoiding the situation of poor contact between the two, being able to continuously supply power to the workpiece to be processed, reducing the conductive frictional force between the conductive component 2 and the extension part 32, reducing the main drive friction power of the whole line, extending the service life of the overall device, and saving electric energy consumption at the same time.

[0041] At the same time, after the surface materials of the conductive component 2 and the hanger 3 are worn, they are directly mixed into the conductive working medium and will not fall into the solution tank again, thus being able to avoid the situation of the plating solution being contaminated by the worn and fallen materials; the conductive working medium can also cool down the conductive component 2, avoiding the problem that the temperature of the conductive component 2 is too high due to frictional heat generation, which in turn affects the conductivity of the conductive component 2, and ensuring the uniform distribution of conduction to the workpiece to be processed.

[0042] In this embodiment, the above-mentioned base body 1 includes a groove with an open top. The inner cavity of this groove is used as the accommodation cavity 11 for accommodating the conductive working medium. The extension part 32 of the above-mentioned hanger 3 can cross a groove wall of the groove and be embedded into the accommodation cavity 11 through the groove opening. When the hanger 3 slides relative to the seat, the extension part 32 can be in sliding contact with the conductive surface 21 of any one of the conductive components 2 to complete the conductive effect.

[0043] In order to ensure stable conduction to the hanger 3, the extension part 32 can be set as a plate, and a surface contact is formed between the conductive component 2 and the conductive surface 21.

[0044] In this embodiment, the two ends of the above-mentioned groove in the sliding direction of the hanger 3 are provided with open openings, so that the conductive working medium can flow from one open opening to the other open opening in the groove, making the conductive working medium in a fluid state in the groove. This conductive working medium can adopt liquid conductive media such as water and lubricating oil.

[0045] The conductive mechanism in this embodiment further includes a supply mechanism, a return groove and a filter. The supply mechanism is used to provide the conductive working medium to the groove, which can ensure that there is enough conductive working medium in the groove to lubricate the conductive surface 21 and the extension part 32. When the conductive working medium is water, the supply mechanism can be a water tank;

[0046] Both ends of the above-mentioned reflux tank are respectively communicated with the inner cavity of the groove through pipelines. The conductive working medium circulates reciprocally in the reflux tank, and the conductive working medium can be reused multiple times. When the conductive working medium circulates in the reflux tank, a cooler can be arranged in the reflux tank. Since the conductive working medium lubricates the conductive component 2 and the extension part 32, and conducts electricity to the conductive component 2, heat will also be generated in the conductive component 2, and thus heat will also be generated between the conductive surface 21 and the extension part 32. Therefore, the conductive working medium can also absorb the generated heat to complete the cooling of the conductive component 2 and the extension part 32. Therefore, the temperature of the conductive working medium will rise, and the cooler can cool the conductive working medium to ensure the constant temperature of the conductive working medium, and can achieve the cooling effect on the conductive component 2 and the extension part 32.

[0047] The above-mentioned filter is arranged on the pipeline between the reflux tank and the [specific part not mentioned]. It can filter the materials in the conductive working medium used multiple times to ensure the purity of the conductive working medium entering the groove.

[0048] In this embodiment, it further includes a biasing component connected to the conductive component 2. The conductive component 2 is subjected to the biasing force of the biasing component, so that the conductive surface 21 tends to be in sliding contact with one side wall of the conductive part. The biasing component can be set as a spring.

[0049] Embodiment No. 2

[0050] The difference between this embodiment and Embodiment 1 is that this embodiment describes a workpiece processing system, which includes at least two sequentially arranged tanks and the conductive mechanism described above. The adjacent two tanks are communicated with each other, and the top of any one tank has a top opening. Electroplating solution or etching solution can be placed inside the tank. The hanger 3 of the conductive mechanism is used to drive the workpiece to be processed to slide in any one tank. When the hanger 3 drives the workpiece to be processed to slide in any one tank, the constant conductive temperature between the conductive component 2 and the hanger 3 can ensure the conductive reliability of the workpiece to be processed, providing a prerequisite for improving the uniformity of electroplating or etching, and can conduct electricity stably to the workpiece to be processed located in the tank, ensuring the effect of electroplating or etching.

[0051] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
