[0002] When the circuit board is electroplated through the electroplating tank, it is clamped under the hanger by multiple spaced-apart clamps, and the conveying mechanism drives the hanger to move so as to drive the circuit board to be electroplated in tanks with different functions. In the traditional vertical continuous electroplating line, the hanger adopts a single-sided cantilever structure, and a gear or a push rod is provided on one side of the top of the hanger. The hanger moves forward on the transmission chain by the gear or the push rod. The conductive structure is arranged on the upper part of the hanger, and the conductive structure is pressed on the conductive copper bar by the weight of the hanger to contact the conductive copper bar for conduction. Since the hanger adopts a single-sided cantilever design, the hanger is unstable in operation during horizontal or vertical movement and is prone to swinging left and right. In addition, the conductive structure relies on the weight of the hanger to press the conductive copper bar for conduction, and there is a serious poor conductivity phenomenon in actual use. Summary of the invention

[0030] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] Example 1

[0032] This embodiment provides a conductive structure such as Figure 1 As shown, it includes a first conductive component, at least two second conductive components and a transmission assembly.

[0033] Among them, at least two second conductive components are located on opposite sides of the first conductive component, the outer edges of the second conductive components can contact and conduct electricity with the external conductive brush, the second conductive components are connected and conducted with the first conductive component, and the transmission component is arranged on the second conductive component and drives the second conductive component to move.

[0034] The conductive structure of this structure has a second conductive component on both sides of the first conductive component, and a transmission component is provided on the second conductive components on both sides. The transmission component is suitable for being respectively arranged on the driving components on both sides and being driven by the driving components to move, so as to drive the conductive structure to move forward. The second conductive component pushes away the conductive brushes on both sides, and the outer edge of the second conductive component contacts the conductive brushes for conduction, and then the cathode current is conducted to the first conductive component, and the first conductive component conducts the current to the clamp, and the clamp conducts the current to the circuit board to provide cathode electricity for the circuit board. Since there are second conductive components and transmission components on both sides of the first conductive component, the conductive structure has good strength, and both sides of the conductive structure can be supported on the driving component to move forward. Compared with the single-sided suspension structure, the conductive structure of this invention is stable in operation, and the second conductive component is in stable contact with the conductive brushes on both sides, and the conduction is stable.

[0035] Specifically, the first conductive component is a conductive plate 1, and the second conductive component is a conductive frame 2. The second conductive component is frame-shaped, has high strength and stable structure. There are two conductive frames 2, and any conductive frame 2 and the conductive plate 1 form a rectangle; the bottom of the conductive plate 1 is provided with a clamping claw that conducts with the conductive plate 1.

[0036] The conductive mode of the conductive frame 2 may be a cathode conductive component as disclosed in the patent document with publication number WO2019119807A1, which is connected to the negative pole of the power supply and includes two rows of conductive brushes, which are arranged opposite to each other and are connected to the cathode of the power supply through wires, and a gap is reserved between the two rows of conductive brushes for the conductive frame 2 and the conductive plate 1 to slide through. A torsion spring is provided on the conductive brush to keep the conductive brush and the conductive frame 2 in good contact and conduction.

[0037] like Figure 2 As shown, the two conductive frames 2 are respectively located on opposite sides of the conductive plate 1 in the thickness direction, and the two conductive frames 2 are symmetrical about the conductive plate 1. The symmetrical arrangement of the conductive frames 2 makes the conductive structure more stable as a whole, and the conductive structure runs stably and is not easy to shake, thereby ensuring that the conductive frames 2 are in stable contact with the conductive brushes for conduction.

[0038] Optimally, both ends of the two conductive frames 2 away from the front and rear ends of the first side 21 of the conductive plate 1 are provided with chamfers, so that the conductive frames 2 can squeeze the conductive brushes on both sides to enter the conductive area when moving forward; both ends of the conductive frames 2 are provided with chamfers, so that the conductive structure can be pushed away from the front or rear end, thereby improving the flexibility of the running direction of the conductive structure.

[0039] The transmission assembly includes a transmission plate 31, a connecting portion 32 and a reinforcing plate 33. The transmission plate 31 is arranged inside the conductive frame 2 along the length direction of the conductive frame 2, and the two ends of the transmission plate 31 are respectively fixed on the inner wall surfaces of the second side 22 and the third side 23 of the conductive frame 2; one end of the reinforcing plate 33 is fixed on the inner wall surface of the first side 21, and the other end is fixed on the upper surface of the transmission plate 31. The arrangement of the reinforcing plate makes the transmission assembly structure stable and runs smoothly, ensuring stable conduction. The transmission plate 31 and the reinforcing plate 33 are located inside the conductive frame, so that the transmission assembly has a higher strength, the conductive structure runs smoothly, and stable conduction is ensured.

[0040] For example, Figure 3 As shown, the connecting part is a rack, and two racks are provided at the bottom of any transmission plate 31. The driving component is a steel belt 4, and a tooth shape matching the rack is provided on the top of the steel belt. The two ends of the conductive structure are respectively driven by the tooth meshing on the steel belt 4. The steel belt drives the transmission plate 31 to move, and the transmission plate 31 drives the conductive structure to move. The operation is stable, it is not easy to jump teeth, the failure rate is low, and the conductivity is stable.

[0041] The upper part of the conductive plate 1 is a hollow structure, which ensures its strength while saving materials. A protrusion 11 extends upward from the top of the conductive plate 1, and a card block is connected to the outside of the protrusion 11. Card slots are provided on both sides of the card block. The lifting device is connected to the card slots on both sides of the card block. When the conductive structure switches the working slot, the lifting device is suitable for lifting the conductive structure and the circuit board upward together, running to the next working slot, and then the lifting device moves downward to put the circuit board into the working slot. The lifting process of the lifting device realizes the switching of the circuit board between different working slots, which can prevent the circuit board from directly entering the next slot horizontally. It needs to squeeze the water retaining roller between the two slots to enter the next slot, and the water retaining roller squeezes and damages the circuit on the circuit board.

[0042] As a first alternative implementation of Example 1, the conductive plate 1 may also be a solid structure without being hollowed out.

[0043] As a second alternative implementation of Example 1, the chamfer may not be set on the conductive frame 2, or a chamfer may be set only at one end of the front end or the rear end of the conductive frame 2, as long as the conductive structure can run to the conductive brush and squeeze the conductive brush away so that the outer edges on both sides of the conductive frame 2 can stably contact the conductive brush for conduction.

[0044] As a third alternative implementation of Example 1, the first conductive component may not be in the shape of a plate. For example, it may be set to a three-dimensional columnar shape, such as a rectangular parallelepiped; as a further deformation, the second conductive component may be set to a solid plate shape, and the plate-shaped second conductive components are symmetrically arranged on two opposite sides of the first conductive component; the outer wall surfaces of the second conductive components on both sides can stably contact the conductive brushes to conduct electricity, and then transfer the current to the first conductive component; when the second conductive component is in the shape of a frame, any second conductive component and the first conductive component can also form a square, a parallelogram, etc., as long as the two outer edges of the second conductive component in contact with the conductive brush are parallel to each other and can respectively abut against the conductive brushes on both sides to conduct electricity.

[0045] As a fourth alternative implementation of Example 1, chains may be provided under the second conductive components on both sides, and gears cooperating with the chains may be provided on the transmission components on both sides to realize transmission of the conductive structure.

[0046] As a fifth alternative implementation of Example 1, the transmission assembly may also be arranged outside the second conductive component. For example, when the second conductive component is in the shape of a solid plate, the transmission assembly may be arranged at the bottom of the second conductive component.

[0047] As a sixth alternative implementation of Example 1, the second conductive component may not be symmetrical with respect to the first conductive component, as long as second conductive components are respectively provided on the opposite sides of the first conductive component, and a transmission component is provided on each second conductive component, and the transmission component is supported on the driving component below and is driven by the driving component to move forward, a supporting transmission can be formed on both sides of the conductive structure, so that the conductive structure can run stably and achieve stable conduction.

[0048] Example 2

[0049] This embodiment provides a hanging tool, such as Figure 1 As shown, it includes the conductive structure in Example 1. The conductive structure is arranged on the upper part of the hanger, and a plurality of clamps connected to the conductive plate 1 are arranged at the lower part, and the clamps are used to clamp the circuit board. During operation, the conductive frame 2 contacts the conductive brushes on both sides to conduct electricity, and the conductive frame 2 conducts the cathode current to the conductive plate 1, and the conductive plate 1 transfers the current to the clamps, and the clamps transfer the current to the circuit board, providing the circuit board with cathode current for the circuit board to complete electroplating in the electroplating tank. Due to the symmetrical conductive structure on the upper part of the hanger, and the driving components are provided on both sides of the first conductive component to support and drive the hanger, the hanger can run stably, the conductivity is stable, and the electroplating quality of the circuit board is improved.

[0050] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
