Description

Technical Field

[0001] The utility model relates to the technical field related to electroplating equipment, and more specifically to a cathode conductive device for tungsten alloy electroplating production. Background Art

[0002] At present, in the tungsten alloy electroplating production line, the electroplating tank is the most widely used electroplating equipment, which can electroplate the workpiece to be electroplated suspended in the plating tank through the plating liquid in the plating tank. Traditional electroplating tanks are equipped with a cathode conductive hanger at the upper opening, and then the workpiece to be electroplated is hung on the cathode conductive hanger, so that the workpiece descends with the cathode conductive hanger and sinks in the plating liquid. In the acidic and alkaline humid environment of electroplating, the matching surface of the cathode conductive hanger is very easy to oxidize and rust, which seriously affects the conductivity of the cathode conductive device, and then affects the quality of the electroplated workpiece, so it needs to be cleaned frequently.

[0003] A document with publication number CN217973461U has been retrieved and disclosed a cathode conductive device for electroplating, comprising a base plate and an insert plate, wherein the bottom surface of the base plate is provided with a slot for plugging and cooperating with the insert plate, and the insert plate is installed in the slot in a plug-in structure and can be removed from the installation slot, so as to facilitate the hanging and unloading of the electroplated workpiece offline, and multiple plug-ins can be placed on the online line in turn to realize the electroplating operation, so as to facilitate continuous operation and thus improve production efficiency.

[0004] In the above-mentioned public documents, although a plug-in installation structure is used in conjunction with the base plate installation to facilitate offline cleaning after the plug-in board is taken out, the cathode conductive column needs to be cleaned together with the plug-in board, but the cathode conductive column is installed in an array at the bottom of the plug-in board. It is inconvenient to clean when there are a large number of cathode conductive columns, and if a single or part of the array-type cathode conductive column is damaged, it cannot be replaced individually, which will affect the use of the entire plug-in board, and the overall replacement increases the maintenance cost.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0032] See also Figures 1 to 7 In the utility model, the cathode conductive device for tungsten alloy electroplating production includes a bottom plate 1 and a conductive plate 2. A through slot 3 for plugging and matching with the conductive plate 2 is provided on the top of the bottom plate 1. The conductive plate 2 is installed in the through slot 3 in a plug-in structure and can be taken out from the through slot 3.

[0033] Among them, a number of conductive seats 4 distributed in an array and passing through the conductive plate 2 are fixedly embedded on the conductive plate 2, a corresponding cathode conductive column 5 is arranged under each conductive seat 4, and conductive shafts 6 distributed in a circular array are fixedly connected to the outer wall of the cathode conductive column, and an installation cavity 7 for accommodating the cathode conductive column 5 and the conductive shaft 6 is opened at the bottom of the conductive seat 4.

[0034] In this embodiment, preferably, a mounting hole 8 communicating with the mounting cavity 7 and for the conductive shaft 6 to pass through is formed at the bottom of the conductive seat 4 , and an L-shaped limiting groove 18 communicating with the mounting hole 8 is formed on the inner wall of the mounting cavity 7 .

[0035] In this embodiment, preferably, a telescopic rod 9 and a spring 10 are fixedly provided on the inner top wall of the mounting cavity 7, a stopper 11 is fixedly provided on the bottom end of the telescopic rod 9, the spring 10 is arranged on the outside of the telescopic rod 9, the bottom end of the spring 10 abuts against the top of the stopper 11, the spring 10 is inserted into the mounting hole 8 with the low-tight stopper 11 in the natural state, the telescopic rod 9, the spring 10 and the stopper 11 are located in the vertical section of the L-shaped limit groove 18, and the conductive shaft 6 can be screwed into the horizontal section of the L-shaped limit groove 18;

[0036] Specifically, since the spring 10 is prone to bending during the compression process, a telescopic rod 9 is provided to allow the spring 10 to be linearly compressed. The telescopic rod 9 adopts the existing public technology and can be retracted and retracted synchronously with the spring 10. During the installation process, the conductive shaft 6 squeezes the block 11 to compress the spring 10. After the conductive shaft 6 is installed, the elastic force of the spring 10 blocks the block 11.

[0037] In this embodiment, preferably, the surface of the stopper 11 is processed into an arc, and the conductive shaft 6 is a cylindrical structure and matches the surface shape of the stopper 11;

[0038] Specifically, during the disassembly process, rotating the cathode conductive column 5 can cause the cylindrical conductive shaft 6 to slide relative to the surface of the stopper 11, so that the spring 10 and the telescopic rod 9 are compressed, thereby completing the disassembly process.

[0039] In this embodiment, preferably, two power connection posts 12 distributed along the diagonal line of the bottom plate 1 are fixedly connected to the bottom plate 1, and two power connection sockets 13 distributed along the diagonal line of the conductive plate 2 are embedded and installed at the bottom of the conductive plate 2, and the power connection posts 12 can be inserted into the power connection sockets 13;

[0040] Specifically, when installed between the conductive plate 2 and the base plate 1, the power post 12 can be inserted into the power socket 13, and the cathode conductive post 5 can conduct electricity to the electroplated workpiece through the conductive plate 2, the conductive seat 4, the conductive shaft 6 and the cathode conductive post 5 in sequence.

[0041] In this embodiment, preferably, evenly distributed bayonet holes 14 are opened on the top of the bottom plate 1, a plurality of positioning rods 15 inserted into the bayonet holes 14 are fixedly provided on the outer ring of the conductive plate 2, and a plurality of elastic buckles 16 corresponding to the bayonet holes 14 and used for clamping the positioning rods 15 are fixedly provided on the top of the bottom;

[0042] Specifically, when installing between the conductive plate 2 and the base plate 1 , the positioning rod 15 can pass through the bayonet 14 to achieve installation positioning, and then snap into the elastic buckle 16 to fix the conductive plate 2 to achieve installation between the conductive plate 2 and the base plate 1 .

[0043] In this embodiment, preferably, the elastic buckle 16 includes a receiving portion 161, a first inclined portion 162, a second inclined portion 163 and a third inclined portion 164 which are connected in sequence from top to bottom, the side of the receiving portion 161 is fixedly connected to the lower end of the first inclined portion 162, the bottom end of the second inclined portion 163 is fixedly connected to the top end of the first inclined portion 162, the bottom end of the third inclined portion 164 is fixedly connected to the top end of the second inclined portion 163, the first inclined portion 162 is inclined inwardly from bottom to top, the second inclined portion 163 is inclined inwardly from bottom to top and the inclination angle is greater than the inclination angle of the first inclined portion 162, and the third inclined portion 164 is inclined outwardly from bottom to top;

[0044] Specifically, during installation, the positioning rod 15 contacts the third inclined portion 164, causing the second inclined portion 163 and the first inclined portion 162 to open until the positioning rod 15 is against the receiving portion 161. Since the inclination angle of the second inclined portion 163 is greater than the inclination angle of the first inclined portion 162, the inner side wall of the second inclined portion 163 and the upper end surface of the receiving plate limit the movement of the positioning rod 15 in the up and down directions. The second inclined portion 163 and the first inclined portion 162 clamp the positioning rod 15 to achieve installation between the conductive plate 2 and the base plate 1.

[0045] In this embodiment, preferably, both sides of the top of the conductive plate 2 are fixedly connected with handles 17, and the handles 17 are made of insulating material;

[0046] Specifically, the handle 17 made of insulating material can facilitate operators to perform operations such as plugging and unplugging.

[0047] The working principle and use process of this utility model:

[0048] By aligning the conductive plate 2 with the through slot 3 on the bottom plate 1, the positioning rod 15 and the bayonet 14 are in the same position, the power post 12 and the power socket 13 are in the same position, and the conductive plate 2 is pressed downward to make the positioning rod 15 snap into the elastic buckle 16, and the power post 12 can be inserted into the power socket 13, so that the conductive plate 2 and the bottom plate 1 are installed; when removing the conductive plate 2, it is only necessary to manually pull the handle 17 upward so that the positioning rod 15 overcomes the elastic force of the elastic buckle 16 to pull out the conductive plate 2;

[0049] The cathode conductive column 5 and the conductive shaft 6 are respectively aligned with the mounting cavity 7 and the mounting hole 8 and inserted, and the conductive shaft 6 squeezes the stopper 11 in the process of passing through the mounting hole 8, so that the spring 10 and the telescopic rod 9 are compressed. When the top of the cathode conductive column 5 contacts the inner top wall of the mounting cavity 7, the conductive shaft 6 passes through the mounting hole 8 and enters the L-shaped limiting groove 18. The cathode conductive column 5 is rotated to move the position of the conductive shaft 6 from the bottom of the stopper 11 to the lateral section of the L-shaped limiting groove 18. At this time, the spring 10 and the telescopic rod 9 are reset to make the stopper 11 block the mounting hole 8, so that the conductive shaft 6 can be limited, and the installation between the cathode conductive column 5 and the conductive seat 4 can be realized;

[0050] When a cathode conductive column 5 is damaged, the cathode conductive column 5 can be rotated in reverse so that the conductive shaft 6 and the surface of the block 11 form relative sliding movement, so that the spring 10 and the telescopic rod 9 are compressed, and the conductive shaft 6 passes through the L-shaped limit groove 18 and is taken out from the mounting hole 8, thereby realizing the disassembly process, which is convenient for disassembly and assembly and facilitates the replacement of a single cathode conductive column 5.

[0051] In summary, the conductive plate 2 and the base plate 1 are detachably installed, which makes it convenient to take out the conductive plate 2 and clean it offline, and each of the cathode conductive columns 5 distributed in an array below the conductive plate 2 can be disassembled and assembled individually. A certain number of cathode conductive columns 5 are equipped according to the required number and position. Each cathode conductive column 5 corresponds to a plated workpiece, which is convenient for batch electroplating of the plated workpieces, that is, high efficiency. At the same time, if a single or part of the cathode conductive column 5 is damaged, it can be disassembled and assembled for individual replacement, which does not affect the use of the entire plug-in board and reduces maintenance costs.

[0052] The electronic components and modules used in the content of this utility model can all be parts that are commonly used in the market and can realize the specific functions in this case, and the specific models and sizes can be selected and adjusted according to actual needs. The electronic components and modules are all connected to an external power supply and a control switch for use. Their specific circuit connection methods and methods of use are commonly used public technologies and will not be elaborated on here.

[0053] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
