Description

Technical Field

[0001] This application relates to the field of electroplating technology, and more particularly to an electroplating apparatus. Background Technology

[0002] Electroplating tanks are equipped with shielding plates to cover areas of the workpiece that do not require electroplating. Due to variations in the size of the workpiece and its placement within the tank, the shielding plates need to be raised and lowered to accommodate different workpieces. Some related technologies utilize steel wire ropes to raise and lower the shielding plates. However, some of the electroplating solution inside the tank seeps into the steel wire rope through its ends, then continues to permeate the entire rope along its internal gaps, eventually reaching the steel wire rope outside the tank. Finally, it leaks out of the tank through the other end of the steel wire rope, causing environmental pollution and increased cleaning costs due to the leakage of electroplating solution. Summary of the Invention

[0003] In view of this, embodiments of this application aim to provide an electroplating apparatus that helps reduce the probability of electroplating solution leakage.

[0004] This application provides an electroplating apparatus, including: An electroplating tank is used to store electroplating solutions and to hold workpieces to be plated. A shield is provided inside the electroplating tank to shield the areas of the workpiece that do not require electroplating. A wire rope assembly and a drive assembly, the wire rope assembly including two rope segments and a connecting assembly, one of the rope segments being connected to the drive assembly and the other rope segment being connected to the shield, the two rope segments being connected by the connecting assembly so that the two rope segments are spaced apart along the height direction; The rope segment connected to the shield is always located inside the electroplating tank, and the rope segment connected to the drive assembly is separated from the electroplating solution by the connecting assembly.

[0005] In some embodiments, the connecting assembly includes an isolation section and a cylindrical body with openings at both ends. The isolation section is disposed inside the cylindrical body to divide the space inside the cylindrical body into two installation spaces, which are arranged axially. The connecting assembly includes two fasteners, and the two rope segments are respectively installed into the two installation spaces through the two fasteners. The highest position of the cylinder is not lower than the liquid level of the electroplating solution.

[0006] In some embodiments, the fastener has a through hole through which the rope segment passes and is located between the isolation portion and the fastener, the fastener being used to abut the rope segment against the isolation portion.

[0007] In some embodiments, the fastener has a through hole through which the rope segment passes; The fastener includes a head and a rod that are connected to each other. The rod is disposed in the installation space. The inner wall of the cylinder has a through-hole. The rope segment passes through the through hole, the gap between the isolation part and the fastener, and the through-hole in sequence, and is located between the head and the end face of the cylinder. The fastener is used to abut the rope segment against the isolation portion, and / or the head is used to abut the rope segment against the end face of the cylinder.

[0008] In some embodiments, the end face of the cylinder includes a first positioning surface and a second positioning surface, the first positioning surface and the second positioning surface are arranged along the axial direction, the first positioning surface is located on the side of the second positioning surface away from the isolation part, and a stepped surface is formed at the junction of the first positioning surface and the second positioning surface. A columnar protrusion is formed on the side of the head facing the isolation part, the stepped surface is located on the outer periphery of the columnar protrusion, and the rope segment is located between the columnar protrusion and the second positioning surface.

[0009] In some implementations, the isolation section and the cylindrical body are integrally formed.

[0010] In some implementations, the fastener is threadedly connected to the cylinder.

[0011] In some implementations, the connecting component is a plastic part.

[0012] In some embodiments, the electroplating apparatus includes a pulley, the drive assembly is disposed on the outer wall of the electroplating tank, and another rope segment is wound around the pulley and connected to the drive assembly.

[0013] In some embodiments, the rope segment includes a rope segment body and a covering, the covering covering the outer periphery of the rope segment body, the rope segment body being a steel wire rope and the covering being a plastic component.

[0014] For ease of description, the electroplating apparatus provided in this application refers to the rope segment connected to the drive assembly as the first rope segment and the rope segment connected to the shield as the second rope segment. The drive assembly moves the first rope segment, thereby moving the entire wire rope assembly to raise and lower the shield. The second rope segment remains inside the electroplating tank, preventing the electroplating solution from seeping out of the tank. The electroplating solution cannot seep into the first rope segment via the second rope segment, nor directly into the first rope segment, nor through the connecting assembly. In other words, the electroplating solution also cannot seep out of the tank via the first rope segment, thus helping to reduce the probability of electroplating solution leakage.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0023] The height direction of this embodiment is the direction indicated by d1 in the figure.

[0024] This application provides an electroplating apparatus; please refer to [link / reference]. Figure 1 and Figure 2 The electroplating apparatus includes an electroplating tank 10, a shield 20, a wire rope assembly 30, and a drive assembly 40.

[0025] Specifically, the electroplating tank 10 is used to store the electroplating solution and to place the workpiece to be plated. A shield 20 is disposed inside the electroplating tank 10 to shield the areas of the workpiece to be plated that do not require electroplating.

[0026] For example, the wire rope assembly 30 includes two rope segments 31 and a connecting assembly 32. One rope segment 31 is connected to the drive assembly 40, and the other rope segment 31 is connected to the shield 20. The two rope segments 31 are connected by the connecting assembly 32 such that the two rope segments 31 are spaced apart along the height direction. See also... Figure 2 and Figure 3 The rope segment 31 connected to the shield 20 is always located inside the electroplating tank 10, and the end of the rope segment 31 connected to the drive assembly 40 near the connecting assembly 32 is separated from the electroplating solution by the connecting assembly 32.

[0027] For ease of description, the rope segment 31 connected to the drive assembly 40 is named the first rope segment 31a, and the rope segment 31 connected to the cover plate 20 is named the second rope segment 31b.

[0028] It should be noted that the two rope segments 31 are spaced apart along the height direction, meaning that the first rope segment 31a and the second rope segment 31b will not be in direct contact. Therefore, the electroplating solution that penetrates into the interior of the second rope segment 31b through the end of the second rope segment 31b will not penetrate into the first rope segment 31a.

[0029] It should be noted that the rope segment 31 connected to the drive assembly 40, i.e. the first rope segment 31a, is separated from the electroplating solution by the connecting assembly 32. This means that the first rope segment 31a will not come into contact with the electroplating solution. Thus, the electroplating solution cannot directly penetrate into the first rope segment 31a, or penetrate into the first rope segment 31a through the connecting assembly 32.

[0030] The method by which the first rope segment 31a is separated from the electroplating solution by the connecting component 32 is not limited. For example, the connection position between the connecting component 32 and the first rope segment 31a can always be higher than the liquid surface of the electroplating solution. Alternatively, please refer to [reference needed]. Figure 2 and Figure 4 The first rope segment 31a is located inside the connecting component 32. The highest position of the connecting component 32 is not lower than the liquid surface of the electroplating solution. In this embodiment, the position of the first rope segment 31a can be lower than the liquid surface of the electroplating solution.

[0031] The electroplating apparatus provided in this embodiment utilizes a drive assembly 40 to move the first rope segment 31a, thereby causing the entire wire rope assembly 30 to move, thus achieving the lifting and lowering of the shield 20. The second rope segment 31b is always located inside the electroplating tank 10, preventing the electroplating solution from seeping out of the electroplating tank 10 through the second rope segment 31b. The electroplating solution cannot seep into the first rope segment 31a through the second rope segment 31b, nor can it directly seep into the first rope segment 31a, nor can it seep into the first rope segment 31a through the connecting assembly 32. In other words, the electroplating solution will also not seep out of the electroplating tank 10 through the first rope segment 31a, thereby helping to reduce the probability of electroplating solution leakage.

[0032] In some embodiments, the connecting assembly 32 includes an isolation portion 322 and a cylindrical body 321 with openings at both ends. The isolation portion 322 is disposed inside the cylindrical body 321 to divide the space inside the cylindrical body 321 into two installation spaces 321a, which are arranged axially. That is, the two installation spaces 321a are located on both sides of the isolation portion 322 along the axial direction.

[0033] Understandably, the two installation spaces 321a are not axially connected.

[0034] For example, the connecting component 32 includes two fasteners 323, and the two rope segments 31 are respectively installed into the two installation spaces 321a by the two fasteners 323, and the highest position of the cylinder 321 is not lower than the liquid level of the electroplating solution.

[0035] In this embodiment, the isolation section 322 separates the two installation spaces 321a to separate the first rope segment 31a from the second rope segment 31b, thereby preventing liquid that has permeated into the second rope segment 31b from permeating into the first rope segment 31a. Since the second rope segment 31b is located inside the cylinder 321, and the highest point of the cylinder 321 is not lower than the surface of the electroplating solution, the second rope segment 31b will not come into contact with the surface of the electroplating solution.

[0036] In some embodiments, the fastener 323 has a through hole 323a through which the rope segment 31 passes and is located between the isolation portion 322 and the fastener 323. The fastener 323 is used to abut the rope segment 31 against the isolation portion 322. In this embodiment, the rope segment 31 is clamped by the interaction force between the fastener 323 and the isolation portion 322.

[0037] In some embodiments, such as Figure 4 and Figure 5 As shown, the fastener 323 includes a head 3231 and a rod 3232 connected to each other. The rod 3232 is disposed in the installation space 321a. The inner wall of the cylinder 321 forms a through-hole 321b. The rope segment 31 passes through the through hole 323a, the gap between the isolation part 322 and the fastener 323, and the through-hole 321b in sequence, and is located between the end faces of the head 3231 and the cylinder 321. Fastener 323 is used to abut the rope segment 31 against the isolation part 322, and / or head 3231 is used to abut the rope segment 31 against the end face of the cylinder 321.

[0038] This embodiment includes the following three cases: The first scenario: The rope segment 31 is clamped using only the interaction force between the fastener 323 and the isolation part 322.

[0039] The second scenario: The rope segment 31 is clamped by the interaction force between the head 3231 and the end face of the cylinder 321.

[0040] The third scenario involves simultaneously clamping the rope segment 31 using the interaction force between the fastener 323 and the isolating part 322, as well as the interaction force between the head 3231 and the end face of the cylinder 321. In this case, applying two interaction forces to the rope segment 31 helps to further improve the stability of the rope segment 31 within the installation space 321a.

[0041] It is understood that this application does not limit the above three situations, and the specific situation can be determined by the weight of the cover plate 20 and the clamping force provided in various situations.

[0042] For example, such as Figure 6 As shown, the end face of the cylinder 321 includes a first positioning surface 3211 and a second positioning surface 3212. The first positioning surface 3211 and the second positioning surface 3212 are arranged along the axial direction, and the first positioning surface 3211 is located on the side of the second positioning surface 3212 away from the isolation part 322. That is to say, the end face of the cylinder 321 is not a plane, but is stepped.

[0043] It is understandable that the first positioning surface 3211, the second positioning surface 3212, and the step surface 3213 are all annular.

[0044] For example, a columnar protrusion 32311 is formed on the side of the head 3231 facing the isolation portion 322, a stepped surface 3213 is located on the outer periphery of the columnar protrusion 32311, and a rope segment 31 is located between the columnar protrusion 32311 and the second positioning surface 3212. This facilitates contact between the head 3231 and the first positioning surface 3211, thereby improving the sealing performance between the fastener 323 and the cylinder 321 and further reducing the probability of electroplating solution entering the cylinder 321.

[0045] In an embodiment where the head 3231 is used to abut the rope segment 31 against the end face of the cylinder 321, the columnar protrusion 32311 abuts the rope segment 31 against the second positioning surface 3212.

[0046] In some embodiments, the isolation portion 322 and the cylinder 321 are integrally formed. This helps to improve the connection stability between the isolation portion 322 and the cylinder 321, and also helps to improve the sealing performance between the isolation portion 322 and the cylinder 321.

[0047] In some embodiments, the fastener 323 is threadedly connected to the cylinder 321.

[0048] The form of fastener 323 is not limited; for example, fastener 323 can be a screw, bolt, etc.

[0049] In some embodiments, the connecting component 32 is made of plastic. That is, the cylinder 321, the isolation portion 322, and the fastener 323 are all made of plastic, which helps to improve the corrosion resistance of the connecting component 32.

[0050] For example, connecting component 32 can be a PVC (Polyvinyl chloride) part. In some embodiments, such as Figure 2 and Figure 3 As shown, the electroplating apparatus includes a pulley 50 and a drive assembly 40 disposed on the outer wall of the electroplating tank 10. A rope segment 31 is wound around the pulley 50 and connected to the drive assembly 40. In this embodiment, the pulley 50 is used to change the direction of movement of the first rope segment 31a, so that the drive assembly 40 can be disposed on the outer wall of the electroplating tank 10, thereby reducing the probability of the electroplating solution contacting the drive assembly 40.

[0051] In some embodiments, rope segment 31 includes a rope segment 31 body and a covering, the covering covering the outer periphery of the rope segment 31 body. The rope segment 31 body is a steel wire rope, and the covering is a plastic part. In this way, the covering can provide protection for the rope segment 31 body, allowing the electroplating solution in the rope segment 31 (e.g., the second rope segment 31b) located in the electroplating solution to enter the interior of the rope segment 31 through the end of the rope segment 31, rather than through the surface of the rope segment 31 along its length, thus helping to reduce the corrosive effect of the electroplating solution on the second rope segment 31b.

[0052] For example, the covering part can be a PVC part.

[0053] The various embodiments / implementations provided in this application can be combined with each other without creating contradictions.

[0054] The above are merely preferred embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
