[0028] In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0029] In one aspect, referring to Figure 1 The present application provides an electroplating device, which comprises a conveying mechanism 200, a plurality of processing units 300, and a power supply structure 100. The power supply structure 100 is used to supply power to each processing unit 300 respectively, and the processing unit 300 is used to process the parts. The conveying mechanism 200 is used to drive each processing unit 300 to move in sequence along a predetermined track. For example, when the conveying mechanism 200 is a chain conveying mechanism, the conveying mechanism 200 drives each processing unit 300 to move along a runway-shaped track.

[0030] In one specific embodiment, the plating device is a plating device, the processing units 300 are plating units, and the power supply structure 100 supplies power to each plating unit so that the electrodes in the plating unit can be powered, thereby enabling the plating process of the plating unit. When the conveying mechanism 200 drives the plating units to move in the plating solution, the contact probability of the parts in the plating units with the plating solution can be increased, thereby improving the uniformity of the plating of the parts. Understandably, in other embodiments of the present application, the processing units can also be other structures, such as electrolytic processing, solar cell processing, etc., mainly processing that requires electricity, which is not limited here.

[0031] On the other hand, referring to Figure 1 and Figure 2 the present application also provides a power supply structure 100, which includes a power supply 1, a main conductor 2, a plurality of sub-conductors 3, and a plurality of wires 4; the power supply 1 is connected to the main conductor 2 and supplies power to the main conductor 2; the plurality of sub-conductors 3 are arranged around the periphery of the main conductor 2 and move around the main conductor 2 in turn, and each sub-conductor 3 is electrically connected to the main conductor 2 through a wire 4; the wire 4 is elastic, and the length of the wire 4 can change with the distance between the sub-conductor 3 and the main conductor 2.

[0032] The power supply 1 is a distribution box, which is used to supply power to the main conductor 2. Of course, in other embodiments of the present application, the power supply 1 can also be a power supply board, which is provided with a socket, and the socket is connected to the power supply to supply power to the main conductor 2.

[0033] The position of the main conductor 2 is relatively fixed, that is, the main conductor 2 does not displace. Each sub-conductor 3 is arranged in each processing unit 300, and the conveying mechanism 200 drives each processing unit 300 to move around the main conductor 2, thereby driving each sub-conductor 3 to move around the main conductor 2 in turn.

[0034] The wire 4 is elastic, which means that the wire 4 can not only realize electrical connection, but also realize electrical connection between two objects with changing distances. The wire 4 can include a copper wire and an insulating material wrapped around the copper wire, and the insulating material is spirally twisted, such as a telephone line, so that the wire 4 is elastic.

[0035] When power supply is performed, the power supply member 1 first supplies power to the main conducting member 2, and the main conducting member 2 supplies power to each of the sub-conducting members 3 through the wires 4 one by one. When the sub-conducting members 3 move around the main conducting member 2, the distance between the sub-conducting members 3 and the main conducting member 2 changes with the movement of the sub-conducting members 3, and the length of the wires 4 changes with the change of the distance between the sub-conducting members 3 and the main conducting member 2, so that the main conducting member 2 can always supply power to each of the sub-conducting members 3, and the power supply is stable.

[0036] The power supply structure 100 provided by the embodiment of the present application is provided with the main conducting member 2 and the plurality of sub-conducting members 3, each of the sub-conducting members 3 is arranged around the periphery of the main conducting member 2 and moves around the main conducting member 2 in turn, so that when power supply is performed, each of the sub-conducting members 3 can be mounted on each of the to-be-powered units in movement, so that the main conducting member 2 fixedly arranged can supply power to each of the to-be-powered units in movement, and in the process of movement of each of the to-be-powered units, since the wires 4 are elastic, even if the distance between the to-be-powered units and the main conducting member 2 constantly changes, the main conducting member 2 can still supply power to each of the to-be-powered units, and the stability of power supply is improved. In addition, the present application can supply power to a plurality of to-be-powered units in movement by using one power supply member 1, the overall structure is simple, the manufacturing is simple, and the implementation is convenient.

[0037] In one embodiment, please refer to Figure 1 Each of the sub-conducting members 3 moves around the main conducting member 2 according to a preset track, wherein the preset track is a racetrack type track, and the main conducting member 2 is located at the position of the center symmetry line of the racetrack type track, and in the process of movement around the main conducting member 2, the distance between the sub-conducting members 3 and the main conducting member 2 first slowly increases, then slowly decreases, then slowly increases again, and then slowly decreases again, so as to complete one round, and the process is repeated in turn. It can be understood that in other embodiments of the present application, the sub-conducting members 3 can also move according to other tracks, for example, a circular track, an elliptical track, a rectangular track, a square track or a regular hexagonal track, etc., as long as the track is a closed track, which is not limited herein.

[0038] In one embodiment, please refer to Figure 3 The length extension direction of the main conducting member 2 is the same as the length extension direction of each of the sub-conducting members 3, that is, in the process of movement of each of the sub-conducting members 3, the main conducting member 2 and each of the sub-conducting members 3 are in a parallel state in the three-dimensional space.

[0039] At least part of the wires 4 are arranged staggered along the length extension direction of the main conductor 2, that is, the connection positions of the wires 4 and the main conductor 2 can be staggered along the length extension direction of the main conductor 2. Meanwhile, the connection ends of the wires 4 and the sub conductors 3 are also staggered along the length extension direction of the main conductor 2, that is, the wires 4 are always staggered along the length extension direction of the main conductor 2 during the movement of the sub conductors 3, which not only avoids the complexity of the structure of the main conductor 2 caused by the wires 4 being connected to the same position of the main conductor 2 along the length extension direction, but also avoids the mutual entanglement of the wires 4 during the movement of the sub conductors 3, which affects the entire power supply structure 100 and the operation of the electroplating device using the power supply structure 100.

[0040] In one embodiment, referring to Figure 1 , the power supply structure 100 includes a plurality of wire groups 01, each wire group 01 is arranged spaced apart along the length extension direction of the main conductor 2, and each wire group 01 includes at least one wire 4. For example, as shown in Figure 1 and Figure 3 , the power supply structure 100 includes 12 sub conductors 3 and 12 wires 4, and the 12 wires 4 are divided into 6 wire groups 01, each wire group 01 includes two wires 4. Among them, the 6 wire groups 01 are arranged spaced apart along the length extension direction of the main conductor 2, that is, six mounting positions are divided on the main conductor 2 along the length extension direction of the main conductor 2, the six mounting positions are arranged spaced apart, and the six wire groups 01 are respectively mounted on the six mounting positions, so that each wire group 01 is staggered along the length direction of the main conductor 2, and the structure interference between the wire groups 01 is avoided. In addition, by arranging a wire group 01 at each length position of the main conductor 2, when the number of each wire group 01 is greater than one, different wires 4 can be used to provide tension in different directions to the main conductor 2 to keep the main conductor 2 balanced. It can be understood that in other embodiments of the present application, the number of wires 4 in each wire group 01 can also be one, three or more than three. When each wire group 01 includes one wire 4, that is, each wire 4 is staggered along the length extension direction of the main conductor 2, and when each wire group 01 includes three or more than three wires 4, the number of wire groups 01 can be reduced, and the length of the main conductor 2 and the sub conductor 3 can also be reduced, thereby reducing the occupied space of the entire power supply structure 100 along the length direction of the main conductor 2, which is not limited here.

[0041] In one embodiment, referring to Figure 1Each group of wire groups 01 includes at least two wires 4; in the same wire group 01, the positions where the at least two wires 4 are connected to the main conductor 2 are located at the same length position of the main conductor 2, the at least two wires 4 are connected to different positions of the main conductor 2 in the circumferential direction, and the at least two wires 4 are arranged at equal intervals in the circumferential direction of the main conductor 2. In this embodiment, by arranging the at least two wires 4 located at the same length position of the main conductor 2 at equal intervals in the circumferential direction of the main conductor 2, the wires 4 in the same wire group 01 are prevented from being entangled with each other, and the connectors for connecting the wires 4 on the main conductor 2 are prevented from interfering with each other. In addition, the wires 4 in the same wire group 01 are connected to different positions of the main conductor 2 in the circumferential direction, so that the forces applied by the wires 4 to the main conductor 2 are evenly distributed in the circumferential direction and offset each other, thereby balancing the force applied to the main conductor 2 and keeping the position stable.

[0042] Optionally, referring to Figure 1 , each sub-conductor 3 moves along a racetrack-shaped track around the main conductor 2, and during the movement of each sub-conductor 3, two sub-conductors 3 are always arranged symmetrically with the center line of the main conductor 2 as the center. Therefore, in this embodiment, each group of wire groups 01 includes two wires 4, and the two wires 4 are connected to different positions of the main conductor 2 in the circumferential direction.

[0043] In one embodiment, referring to Figure 1 , the connection positions of the wires 4 on the main conductor 2 are arranged at equal intervals in the circumferential direction of the main conductor 2, for example Figure 1 , the 12 wires 4 are arranged at equal intervals in the circumferential direction, so that the wires 4 are connected to the main conductor 2 in a straight line without detours.

[0044] In another embodiment of the present application, the length extension direction of the main conductor 2 can also be different from the length extension direction of each sub-conductor 3. For example, the main conductor 2 has a long strip structure, and the sub-conductors 3 are not long strip structures, but the sub-conductors 3 are arranged at intervals in the length extension direction of the main conductor 2 in space, one end of each wire 4 connected to the main conductor 2 is arranged at intervals in the length extension direction of the main conductor 2, and the other end of each wire 4 is connected to each sub-conductor 3. Therefore, the other end of each wire 4 is also arranged at intervals in the length extension direction of the main conductor 2, so that no matter how the sub-conductors 4 move, the wires 4 are arranged at intervals in the length extension direction of the main conductor 2, thereby preventing the wires 4 from being entangled with each other.

[0045] In another embodiment of the present application, the length extension direction of the main conducting member 2 can also be different from the length extension direction of each sub-conducting member 3. For example, the main conducting member 2 is in a long strip structure, while the sub-conducting member 3 is not in a long strip structure, one end of each wire 4 connected with the main conducting member 2 is staggered along the length extension direction of the main conducting member 2, and the other end of each wire 4 is connected with each sub-conducting member 3 respectively. In this embodiment, since one end of each wire 4 is staggered, the mutual entanglement of each wire 4 can also be avoided.

[0046] In one embodiment, the main conducting member 2 is arranged to rotate around the center line of the main conducting member 2. For example, referring to Figure 3 , the external device to which the power supply structure 100 is applied is provided with a frame 400, that is, the electroplating device also comprises the frame 400, and the main conducting member 2 is arranged to rotate on the frame 400. Specifically, the frame 400 is provided with through holes at two opposite positions, and the opposite ends of the main conducting member 2 along the length direction are arranged to rotate in the two through holes respectively. When each sub-conducting member 3 moves along the runway-type track under the driving of the external conveying mechanism, each sub-conducting member 3 pulls each wire 4 along the circumferential direction, thereby driving the main conducting member 2 to rotate around the center line thereof. In this embodiment, the main conducting member 2 is arranged to rotate around the center line thereof, so that when each sub-conducting member 3 moves along the runway-type track, each wire 4 will also be pulled to move. In order to avoid the entanglement of each wire 4 on the main conducting member 2 and the mutual entanglement of each wire 4, the main conducting member 2 is arranged to rotate around the center line thereof.

[0047] In one embodiment, referring to Figure 3 , the main conducting member 2 comprises a copper rod 21 and an insulating sleeve 22 covering the surface of the copper rod 21, and the copper rod 21 is provided with a first connecting terminal 23 for connecting with the wire 4, and the first connecting terminal 23 penetrates through the insulating sleeve 22 to connect with the wire 4.

[0048] In one embodiment, referring to Figure 3The main electrically conductive part 2 further comprises a plurality of sealing sleeves 24, which are respectively sleeved at different positions of the insulating sleeve 22 along the axial direction. The insulating sleeve 22 is provided with a through slot 221 at a position corresponding to the first connecting terminal 23, and the sealing sleeve 24 is provided with a connecting hole 243 at a position corresponding to the through slot 221.

When the first connecting terminal 23 is penetrated through the connecting hole 243, the first sealing ring 25 abuts against the outer peripheral wall of the first connecting terminal 23, thereby realizing the connection between the first connecting terminal 23 and the sealing sleeve 24, and further realizing the sealing connection between the first connecting terminal 23 and the insulating sleeve 22.

The two ends of the two sleeve bodies 241 along the axial direction are buckled with each other along the radial direction and locked, and the two sleeve bodies 241 are sealingly connected with the insulating sleeve 22 through the second sealing ring at the buckled positions. At least one of the sleeve bodies is provided with the above-mentioned connecting hole 243.
