Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of electroplating, and more particularly relates to an electroplating device. BACKGROUND

[0002] Currently, common electroplating methods on the market include hanging plating, barrel plating, continuous plating, brush plating, etc. Each electroplating method has its own limitations. For example, in the hanging plating process, the structure for picking up the workpiece is attached to the contact part of the workpiece, making it difficult to form a plating layer on the contact part, which needs to be handled manually later, consuming time and effort. In addition, there are subtle differences between the plating layer formed by manual addition and the plating layer formed by hanging plating, ultimately resulting in low efficiency and poor electroplating effect. For another example, in the barrel plating process, the parts are placed in a barrel containing electrodes and electroplating solution, and the plating layer is formed on the surface of the parts through the rolling of the barrel. However, the parts and the electrodes collide probabilistically, which may result in a thinner electroplating layer on the inner parts and a thicker electroplating layer on the outer parts, ultimately causing uneven electroplating layers on each part.

DETAILED DESCRIPTION

[0034] In order to make the technical problems to be solved by the present application, technical solutions and beneficial effects clearer, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application.

[0037] In addition, the terms "first", "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of 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 "multiple" is two or more, unless otherwise specifically limited.

[0038] Please refer to Figure 1 The electroplating device provided by the embodiment of the present application will be described. The electroplating device is used to realize the electroplating process of batch small parts.

[0039] Specifically, the electroplating device comprises a plurality of electroplating units 1, a driving mechanism 3 and a conveying mechanism 2; the electroplating units 1 are distributed with electrodes, and the plurality of electroplating units 1 are sequentially and spacedly installed on the conveying mechanism 2; the conveying mechanism 2 is used to suspend each electroplating unit 1 in the electroplating solution and drive each electroplating unit 1 to move along a preset track to realize hanging plating; the driving mechanism 3 is connected with each electroplating unit 1 respectively, and the driving mechanism 3 is used to drive each electroplating unit 1 to rotate and roll respectively, so that the parts in the electroplating unit 1 tumble to realize roll plating.

[0040] It should be noted that the electroplating device of the present application needs to be immersed in the electroplating solution as a whole during electroplating, the surface of the electroplating unit 1 is distributed with small holes, the aperture of the small holes is smaller than the size of the parts, and the electroplating solution can enter the inside of the electroplating unit 1 from the small holes, but the parts in the inside of the electroplating unit 1 cannot fall out from the small holes. Since the electroplating unit 1 can enter the electroplating solution, the parts act as cathodes, the inside of the electroplating unit 1 is distributed with electrodes, the electrodes act as anodes, and the driving mechanism 3 can drive the electroplating unit 1 to rotate and tumble, so that the parts continuously tumble and fall in the electroplating unit 1 to collide with the anodes, the cathode and anode electrodes are connected to form a current, and thus the plating of a metal layer on the surface of the parts begins.

[0041] Secondly, in the process of barrel plating of the parts in the electroplating unit 1, the conveying mechanism 2 drives the electroplating unit 1 to move along a preset track in the electroplating solution, for example, to make reciprocating linear motion, circular motion, closed motion of any shape, etc. In summary, in the process of barrel plating, the electroplating unit 1 can continuously move in the electroplating solution to continuously increase the collision probability between the parts and the electrode, so that the plating layer on the surface of the parts will also become more and more uniform.

[0042] In addition, it should be noted that the plurality of electroplating units 1 are sequentially and spacedly installed on the conveying mechanism 2. In the entire electroplating process, the plurality of electroplating units 1 can be simultaneously fed, and then the conveying mechanism 2 drives the plurality of electroplating units 1 to move in the electroplating solution for a preset time, and then the plurality of electroplating units 1 are simultaneously fed to realize batch barrel plating. Alternatively, each electroplating unit 1 can be fed separately, i.e. in the preset track, a feeding station and a discharging station are arranged, and when each electroplating unit 1 moves to the feeding station, the electroplating unit 1 is fed, and then the electroplating units 1 reaching the feeding station are sequentially fed, and the electroplating units 1 reaching the discharging station are simultaneously discharged. Thus, the waiting time for feeding and discharging is reduced, and the electroplating efficiency is improved.

[0043] The electroplating device of the present application realizes batch electroplating process of parts through the arrangement of the driving mechanism 3 and the plurality of electroplating units 1. Through the arrangement of the conveying mechanism 2 and the sequential and spaced installation of the plurality of electroplating units 1 on the conveying mechanism 2, the conveying mechanism 2 is used to suspend each electroplating unit 1 in the electroplating solution and drive each electroplating unit 1 to move along a preset track, i.e. to make the electroplating unit 1 move in the electroplating solution while barrel plating the parts, which can continuously increase the collision probability between the parts and the electrode, so that the plating layer on the surface of the parts will also become more and more uniform, and the electroplating effect is better. In addition, due to the arrangement of the driving mechanism 3 and the conveying mechanism 2, the electroplating unit 1 not only has self-rolling motion, but also can be driven to move by the conveying mechanism 2, which increases the motion of the parts and thus improves the electroplating efficiency of the parts. In addition, the arrangement of the plurality of electroplating units 1 also improves the electroplating efficiency of the electroplating device.

[0044] In one embodiment, the electroplating device has a feeding station and a discharging station, which are respectively arranged in the movement preset track of the electroplating units 1. Each electroplating unit 1 is driven by the conveying mechanism 2 to sequentially reach the feeding station and the discharging station, that is, during the electroplating process, the feeding equipment continuously feeds the electroplating unit 1 reaching the feeding station, and at the same time, the discharging station has the receiving equipment continuously receiving the parts discharged from the discharging station. In summary, during the electroplating process, the conveying mechanism 2 and the driving mechanism 3 are always working, even during the feeding and discharging process, and thus the electroplating efficiency of the entire electroplating device is improved. It can be understood that in other embodiments of the present application, according to the actual design situation, the above-mentioned multiple electroplating units 1 can also be simultaneously fed and discharged, and thus the conveying mechanism 2 and the driving mechanism 3 stop moving when feeding or discharging, which is not limited herein.

[0045] In one embodiment, the movement of the electroplating unit 1 can be a closed loop movement, for example, each electroplating unit 1 is driven by the conveying mechanism 2 to move along a circular track, or each electroplating unit 1 is driven by the conveying mechanism 2 to move along a runway track, or each electroplating unit 1 is driven by the conveying mechanism 2 to move along other irregular closed loop. In summary, during the movement of each electroplating unit 1, each electroplating unit 1 is sequentially and spacedly arranged in the closed loop, and a feeding station and a discharging station are arranged in the closed loop, so that the electroplating unit 1 is fed from the feeding station, and when the electroplating unit 1 moves from the feeding station to the discharging station, the part electroplating is completed and discharged at the discharging station. Since the feeding station and the discharging station are in a closed loop, the electroplating unit 1 needs to move to the feeding station for feeding after discharging, so as to give the electroplating unit 1 a pause time between discharging and feeding, so as to prevent the electroplating unit 1 from directly feeding after discharging, which causes conflict between feeding and discharging. It can be understood that in other embodiments of the present application, the movement of the above-mentioned electroplating unit 1 can also be a reciprocating linear movement, and each electroplating unit 1 can be simultaneously fed and discharged, and then synchronously linearly reciprocated, which is not limited herein.

[0046] In one specific embodiment, please refer to Figure 1 , the movement of the electroplating unit 1 is along a runway track, and the runway track is vertically arranged, and the feeding station and the discharging station are respectively arranged at two positions close to the top and opposite to each other of the runway track. The electroplating unit 1 moves downward along the runway track from the feeding station to the discharging station, and the length can be set according to actual needs to ensure that the part in the electroplating unit 1 is electroplated when the electroplating unit 1 moves to the discharging station. After discharging, the electroplating unit 1 moves upward and returns to the feeding station.

[0047] In one embodiment, please refer to Figure 1 andFigure 2 The electroplating device further comprises a frame 6, and the conveying mechanism 2 and the driving mechanism 3 are both mounted on the frame 6. Specifically, the conveying mechanism 2 comprises two groups of conveying structures 22, which are mounted on the frame 6 at intervals; the opposite ends of the electroplating unit 1 are respectively mounted on the two groups of conveying structures 22; the conveying structure 22 is a transmission chain conveying structure, and the two groups of transmission chain conveying structures are arranged at intervals in the horizontal direction and vertically, and drive each electroplating unit 1 to move along the vertically arranged runway track. This not only enables continuous movement of multiple electroplating units 1, but also enables each electroplating unit 1 to be at a certain height in the electroplating solution, so that the parts are in full contact with the electroplating solution, which is beneficial to the electroplating of the parts. Finally, the entire electroplating device occupies less space in the transverse direction, which is beneficial to placing more electroplating devices to realize larger batch electroplating processes.

[0048] Among them, the number of electroplating units 1 can be set according to actual needs, and the size of the transmission chain conveying structure can also be appropriately adjusted according to the number of electroplating units 1.

[0049] Please refer to Figure 2 The frame 6 comprises a plurality of cross beams 61 and a plurality of longitudinal beams 62, which are respectively vertically and alternately connected to form a square frame structure. The frame 6 further comprises two side plates 63, which are respectively vertically arranged and arranged at intervals in the horizontal direction, and the two side plates 63 are respectively fixedly connected with each cross beam 61 and longitudinal beam 62. The two transmission chain conveying structures are respectively mounted on the two side plates 63.

[0050] Specifically, please refer to Figure 1 and Figure 2 The conveying mechanism 2 further comprises a conveying driving member 21 and a synchronization structure 26. The conveying driving member 21 is specifically a motor, which is mounted on the outside of the frame 6 through a mounting seat. The conveying driving member 21 is connected with one of the conveying structures 22 to drive the conveying structure 22 to move, and the synchronization structure 26 is connected between the two conveying structures 22 to enable the two conveying structures 22 to move synchronously. Through the arrangement of the synchronization structure 26, only one conveying driving member 21 needs to be arranged to synchronously drive the two groups of conveying structures 22 to move, so as to convey each electroplating unit 1 to realize hanging plating, thereby saving the cost and assembly space of the conveying driving member 21.

[0051] Specifically, the transmission chain conveying structure includes two first sprockets 221 and a first transmission chain 222. The two first sprockets 221 are spaced apart along the vertical direction and rotatably arranged on the side plates 63. The first transmission chain 222 is arranged around the two first sprockets 221 and is in transmission connection with the two first sprockets 221, respectively. The conveying driving member 21 is connected to one of the first sprockets 221 of the transmission chain conveying structure located at the upper side through the shaft coupling 23, the gear reducer 24 and the first connecting shaft 25. The two first sprockets 221 of the transmission chain conveying structure located at the upper side are synchronously connected through the synchronous structure 26. When the conveying driving member 21 is started, the conveying driving member 21 drives the first sprocket 221 of the transmission chain conveying structure located at the upper side through the shaft coupling 23, the gear reducer 24 and the first connecting shaft 25, and then drives the corresponding first transmission chain 222 to move. At the same time, the synchronous movement of the two first transmission chains 222 of the two transmission chain conveying structures is realized through the synchronous structure 26, and then the movement of each electroplating unit 1 is realized along with the movement of the first transmission chain 222.

[0052] Please refer to Figure 1 , the outer shape of the two side plates 63 is set to be matched with the shape of the two first transmission chains 222. The two first sprockets 221 are arranged at the upper and lower ends of the outer side of the side plates 63, respectively. The first transmission chain 222 is also arranged at the outer side of the side plates 63.

[0053] Please refer to Figure 2 and Figure 3 , the synchronous structure 26 includes a synchronous shaft 261 and two groups of second transmission chain structures 262. One group of second transmission chain structures 262 is connected between the first connecting shaft 25 and the synchronous shaft 261, so that the synchronous shaft 261 and the first connecting shaft 25 are synchronously rotated through the second transmission chain structure 262. The first sprocket 221 of the other transmission chain conveying structure located at the upper side is rotatably arranged on the corresponding side plate 63 through the second connecting shaft 27. The other group of second transmission chain structures 262 is connected between the synchronous shaft 261 and the second connecting shaft 27, so that the second connecting shaft 27 and the synchronous shaft 261 are synchronously connected, and then the synchronous movement of the two groups of transmission chain conveying structures is realized.

[0054] In one embodiment, please refer to Figure 1 and Figure 2 , the driving mechanism 3 includes a transmission member 31 and a plurality of matching members 32. The plurality of matching members 32 are arranged on the plurality of electroplating units 1, specifically, one matching member 32 is arranged on one electroplating unit 1. The transmission member 31 extends along the movement direction of the electroplating unit 1. Each matching member 32 is in transmission connection with different positions of the transmission member 31 in the movement process of the electroplating unit 1. The transmission member 31 can move along the movement direction of the electroplating unit 1 after being driven to rotate each matching member 32 to drive each electroplating unit 1 to roll.

[0055] It should be noted that the movement track of the electroplating unit 1 is runway type, so when the transmission member 31 extends along the movement direction of the electroplating unit 1, the transmission member 31 also extends along the runway type track, and the transmission member 31 moves along the runway type track after being driven. In this way, no matter where the electroplating unit 1 moves to, the matching member 32 thereon can drive the corresponding transmission member 31 to move, so that the movement of one transmission member 31 can drive the rotation of multiple matching members 32, and further drive the rotation of multiple electroplating units 1.

[0056] In the present application, since multiple electroplating units 1 are in constant motion, the electroplating unit 1 will appear in countless positions during the movement, so it is difficult to drive the electroplating unit 1 to roll by a fixed driving structure. Through the arrangement of the transmission member 31 and the multiple matching members 32, and the movement of the transmission member 31 after being driven, only one external drive is needed to drive the multiple movable electroplating units 1 to rotate through the transmission member 31 and the multiple matching members 32, which is simple in structure and saves the number of driving members and cost.

[0057] In a specific embodiment, please refer to Figure 1 and Figure 2 The above-mentioned transmission member 31 is a second transmission chain, and the above-mentioned matching member 32 is a second sprocket. Each second sprocket is meshingly connected with different positions of the second transmission chain. Through the movement of the second transmission chain, each second sprocket is driven to rotate, and further drive each electroplating unit 1 to rotate, so that the parts in the electroplating unit 1 are tumbled. It can be understood that in other embodiments of the present application, according to the actual design situation and specific requirements, the above-mentioned transmission member 31 and matching member 32 can also be other structures. For example, when the transmission member 31 is a conveyor belt with transmission teeth on the outer surface, the conveyor belt is equivalent to a rack, and the matching member 32 can be a gear. Multiple gears are meshingly connected with different positions on the outer surface of the conveyor belt, so as to drive each gear to rotate respectively.

[0058] In an embodiment, please refer to Figure 1 and Figure 2 The driving mechanism 3 further comprises a rotating driving member 33 and two third sprockets 34. The transmission member 31 is a double-row chain, and the matching member 32 is a fourth sprocket. The two third sprockets 34 are respectively arranged in a vertical direction and are respectively rotatably arranged on the side plates. The rotating driving member 33 is connected with one of the third sprockets 34. The double-row chain is sleeved on the two third sprockets 34. The two third sprockets 34 are meshingly connected with the inner side of one of the two chains of the double-row chain. Each fourth sprocket is meshingly connected with the outer side of the other chain of the double-row chain. In this embodiment, through the arrangement of the double-row chain, the third sprocket 34 and the fourth sprocket are meshingly connected with two different chains, so as to prevent the movement of the third sprocket 34 and the fourth sprocket from being interfered.

[0059] In the embodiment, the first sprocket 221 and the third sprocket 34 are arranged at the outer side and the inner side of the side plate 63 respectively, the first sprocket 221 is coaxially connected with the third sprocket 34, and the third sprocket 34 is rotatably sleeved on the first connecting shaft 25. In this way, the first chain and the double-row chain are arranged in the same center line, that is, the movement trajectories of the double-row chain are similar.

[0060] Please refer to Figure 2 The rotating driving member 33 drives the third sprocket 34 to move through the third transmission chain structure 35.

[0061] In addition, since the electroplating unit 1 has two ends arranged oppositely, two sets of driving mechanisms 3 are required for the electroplating unit 1, and the two sets of driving mechanisms 3 are symmetrically arranged on the two side plates 63 and synchronously drive the two ends of the electroplating unit 1 to rotate synchronously. It can be understood that in other embodiments of the present application, the two side barrel plating driving mechanisms 3 can also be synchronously connected through a synchronous member when the structure permits, so that the number and cost of the rotating driving members 33 can be saved.

[0062] In another embodiment of the present application, since the third sprocket 34 and the first sprocket 221 are coaxially arranged and both are sleeved on the first connecting shaft 25, the rotating driving member 33 can not be arranged, but the third sprocket 34 and the first connecting shaft 25 are fixedly connected, the first connecting shaft 25 drives the third sprocket 34 to rotate, thereby driving the double-row chain to move, so that the movement and rotation of the electroplating unit 1 can be driven by one conveying driving member 21, thereby saving the number and cost of the driving members.

[0063] In another embodiment of the present application, when each electroplating unit 1 moves synchronously through the conveying mechanism 2, the driving mechanism 3 can be arranged on the conveying mechanism 2, and then each electroplating unit 1 is driven to move. At this time, the driving mechanism 3 is relatively easy to realize, for example, a plurality of gears meshing with each other can be driven by one motor to drive each electroplating unit 1 to rotate respectively.

[0064] In one embodiment, the conveying mechanism 2 is vertically arranged and used to drive each electroplating unit 1 to move along a vertically arranged racetrack trajectory. For the feeding and discharging of the electroplating unit 1, an opening is generally arranged on the electroplating unit 1, and the electroplating unit 1 is fed or discharged through the opening. Since the electroplating unit 1 moves with the first chain, when the electroplating unit 1 moves to the position of the bottom arc or the top arc of the first chain, the electroplating unit 1 will rotate, and the rotation of the electroplating unit 1 will cause the opening of the electroplating unit 1 to change. For example, the bottom arc of the first chain will have a 180-degree change, so the electroplating unit 1 will also have a 180-degree rotation. If the opening faces upward before passing through the bottom arc, it will face downward after passing through the bottom arc, causing the part to fall out of the opening.

[0065] For this case, the traditional method is to set a cover at the opening, cover the opening through the cover, prevent the parts from falling out, and then open the cover when discharging. However, since all the electroplating units 1 will not only move with the first chain, but also be driven to roll by the driving mechanism 3, it will be relatively complex to set a cover at the opening and set a structure for automatically opening and closing the cover, which will affect the overall operation of the electroplating unit 1.

[0066] For this, the application sets a guide structure 4 connected between the frame 6 and the electroplating unit 1, and used for guiding the electroplating unit 1 to make the opening of the electroplating unit 1 face a predetermined direction. Specifically, the guide structure 4 makes the electroplating unit 1 not rotate when passing through the bottom arc of the first chain, so as to ensure that the opening of the electroplating unit 1 is always upward, thereby preventing the parts from falling out when the electroplating unit 1 passes through the bottom arc of the first chain.

[0067] Please refer to Figure 4 and Figure 5 , the guide structure 4 includes a first guide rail 41 and a sliding piece 45, the first guide rail 41 is formed with a semicircular first guide groove, and the sliding piece 45 is slidingly arranged in the first guide groove; the sliding piece 45 includes a first guide block 451 and a second guide block 452 arranged in layers; during the sliding piece 45 is slidingly arranged in the first guide groove, the first guide block 451 and the second guide block 452 alternately form a rotation limiting fit with different depth positions on the sidewall of the first guide rail, so as to adjust the sliding direction of the sliding piece 45 in the first guide rail.

[0068] It should be noted that the first guide block 451 and the second guide block 452 are arranged in layers, and when the sliding piece 45 is slidingly arranged in the first guide groove, the first guide block 451 and the second guide block 452 are located at different depth positions of the first guide groove, that is, the stacking direction of the first guide block 451 and the second guide block 452 corresponds to the depth direction of the first guide groove, specifically, the first guide block 451 is located at a deeper position of the first guide groove than the second guide block 452. Similarly, when cooperating with the sidewall of the first guide groove, the first guide block 451 cooperates with the position close to the bottom of the sidewall of the first guide groove, and the second guide block 452 cooperates with the position close to the top of the sidewall of the first guide groove.

[0069] Further, during the sliding of the sliding member 45 in the first guide groove, the first guide block 451 and the second guide block 452 alternately form the rotational limiting cooperation with the sidewall of the first guide rail, that is, during the sliding of the sliding member 45 to different sections, it is possible that the first guide block 451 forms the rotational limiting cooperation with the sidewall of the first guide rail 41, and it is also possible that the second guide block 452 forms the guide cooperation with the sidewall of the first guide rail 41. The first guide groove is in the shape of a semicircular arc, and the sidewall of the first guide rail 41 also extends along the semicircular arc. During the sliding of the sliding member 45, it is impossible to always cooperate with the sidewall of the first guide rail 41. Therefore, the sliding member 45 is divided into the first guide block 451 and the second guide block 452 arranged in layers, and the first guide block 451 and the second guide block 452 cooperate with the sidewall at different positions, so as to finally achieve the purpose that the orientation of the sliding member 45 is substantially unchanged. In the present application, the different guide cooperations at different sections are used to offset the change in the orientation of the sliding member 45 due to the different sections. For example, in one section, the first guide block 451 and the sidewall of the first guide rail 41 are guided and cooperated with each other, so that the sliding member 45 is deflected in the clockwise direction. In another section, the second guide block 452 and the sidewall of the first guide rail 41 are guided and cooperated with each other, so that the sliding member 45 is deflected in the counterclockwise direction. Thus, after the sliding of the sliding member 45 in the whole first guide rail 41, the overall orientation of the sliding member 45 does not change too much, and the opening of the electroplating unit 1 on the sliding member 45 does not face downward to pour out the material.

[0070] In one embodiment, referring to Figure 5 , the first guide rail 41 includes a first guide section 411, a second guide section 412 and a third guide section 413, and the first guide section 411 and the third guide section 413 are symmetrically connected to opposite ends of the second guide section 412. Specifically, referring to Figure 5 , the second guide section 412 is a BC section, and the first guide section 411 and the second guide section 412 are AB section and CD section respectively.

[0071] The second guide block 452 can form a rotation limiting cooperation with the first sidewall 4111 of the first guide segment 411 and the third sidewall 4131 of the third guide segment 413 respectively; the first guide block 451 forms a rotation limiting cooperation with the second sidewall 4121 of the second guide segment 412. Specifically, taking the sliding member 45 sliding in the first guide rail 41 from left to right counterclockwise as an example, the sliding member 45 slides into the first guide segment 411, at this time, the second guide block 452 forms a rotation limiting cooperation with the first sidewall 4111 of the first guide segment 411, so that the position of the sliding member 45 in the first guide segment 411 remains basically unchanged; then, the sliding member 45 slides into the second guide segment 412, at the time when the second guide block 452 cannot cooperate with the second sidewall 4121 of the second guide segment 412, the first guide block 451 forms a rotation limiting cooperation with the second sidewall 4121 of the second guide segment 412, so that the position of the sliding member 45 does not change too much; when the sliding member 45 slides to the third guide segment 413, because the arc of the third guide segment 413 and the arc of the first guide segment 411 are symmetrically arranged, the second guide block 452 can cooperate with the third sidewall 4131 of the third guide segment 413 to keep the position of the sliding member 45 basically unchanged when passing through the first guide segment 411, the second guide segment 412 and the third guide segment 413.

[0072] In one embodiment, referring to Figures 5 to 7 The surface of the first guide block 451 has two first right angles 4511 symmetrically arranged in the circumferential direction, the second guide block 452 has two second arc surfaces 4523 symmetrically arranged in the circumferential direction, and the two first right angles 4511 and the two second arc surfaces 4523 are one-to-one corresponding in the stacking direction of the first guide block 451 and the second guide block 452. The first guide segment 411 has two oppositely arranged first sidewalls 4111, the first sidewall 4111 located on the outer side is formed with a first clamping groove 4112 and a third arc surface 4113, and the first clamping groove 4112 is located at the bottom side of the third arc surface 4113; the first sidewall 4111 located on the inner side of the first guide segment 411 is formed with a first gap 4115 by removing material, that is, the first guide segment 411 does not form a sidewall close to the inner side.

[0073] When the slider 45 slides downwards onto the first guide section 411 with its two first right angles 4511 positioned at the lower left and upper right corners respectively, the opening of the electroplating unit 1 mounted on the slider 45 is facing upwards. As the slider 45 slides downwards, the first right angle 4511 at the lower left corner, due to inertia, vertically engages with the first slot 4112 of the outer first sidewall 4111. The second arc surface 4523 of the second guide block 452 abuts against the third arc surface 4113, thus preventing the slider 45 from rotating during sliding. Furthermore, since the slider 45 slides downwards, its point of force is on the outer first sidewall 4111, thus eliminating the need for an inner first sidewall 4111. Simultaneously, the first notch 4115 allows the first right angle 4511 at the upper right corner to slide along it without structural interference with the first guide section 411. It is understood that in other embodiments of this application, the structures of the two first sidewalls 4111 of the first guide segment 411 may also be set to be the same, and this is not a unique limitation.

[0074] In one embodiment, see Figure 6 The first slot 4112 extends along the length of the first guide segment 411. The first slot 4112 has a first stop wall 4114 near the second guide segment 412. The first stop wall 4114 is used to stop the first right angle 4511 so that the slider 45 rotates by a first preset angle. Specifically, the first slot 4112 is an arc-shaped groove on the outer side wall 4111 of the first guide segment 411. The first slot 4112 passes through the inner and outer sides of the first side wall 4111, and the first stop wall 4114 is the terminal side wall of the first slot 4112. When the slider 45 slides along the first guide section 411, the first right angle 4511 located at the lower left corner slides along the first slot 4112 until the first right angle 4511 abuts against the first stop wall 4114. Due to inertia, the first right angle 4511 will rotate counterclockwise due to the stop of the first stop wall 4114 until the first right angle 4511 slides out of the first slot 4112, and one right angle surface of the first right angle 4511 abuts against the second side wall 4121 located on the outer side of the second guide section 412. The slider 45 then slides stably into the second guide section 412.

[0075] In this embodiment, when the first right angle 4511 slides to its lowest point in the first slot 4112, the first guide rail 41 begins to turn. At this point, the limiting position between the first right angle 4511 and the first slot 4112 can no longer ensure that the direction of the slider 45 remains unchanged. Therefore, other positions of the slider 45 are needed to cooperate with the second guide segment 412 to keep the orientation of the slider 45 within a certain range. Since the slider 45 cannot stably slide into the second guide segment 412 in its current state, the first stop wall 4114 is provided to push and rotate the slider 45 so that it can slide precisely into the second guide segment 412.

[0076] In one embodiment, see Figure 5 and Figure 7 The first guide block 451 has two first right angles 4511 symmetrically arranged circumferentially, and a first arc surface 4513 is connected between the two ends of the two first right angles 4511. The two first arc surfaces 4513 are concentric and symmetrically arranged. The two second sidewalls 4121 of the second guide section 412 each have a fourth arc surface 4122. The distance between the two fourth arc surfaces 4122 is adapted to the diameter of the two first arc surfaces 4513. In the second guide section 412, the first arc surface 4513 and the first right angle 4511 alternately abut against the fourth arc surface 4122.

[0077] Specifically, the first right angle 4511 is formed by the intersection of two mutually perpendicular first right angle surfaces 4512. The two first right angle surfaces 4512 of the first right angle 4511 are respectively tangent to two first arc surfaces 4513, and the diameter of the first arc surface 4513 is adapted to the distance between the inner and outer second sidewalls 4121 of the second guide section 412.

[0078] The second guide section 412 is specifically divided into two parts, such as Figure 5As shown, respectively, are the BK segment and the CK segment. For the BK segment, the sliding member 45 is stopped after rotation by the first stop wall 4114, and the two first right-angled faces 4512 of the two first right angles 4511 are respectively matched with the two fourth arc faces 4122 for sliding. Since in the BK segment, the sliding member 45 is sliding downward along the arc, and the fourth arc face 4122 of the second guide segment 412 located below has an upward stopping force on the first right angle 4511 thereon, the first right-angled face 4512 of the first right angle 4511 is always arranged in abutment with the fourth arc face 4122, that is, the sliding member 45 is angularly rotated along the arc of the fourth arc face 4122 to slide to the K position, and the first guide block 451 is just slid to the position where the opposite first right-angled faces 4512 of the two first right angles 4511 are in a horizontal state. At this time, the opening of the electroplating unit 1 on the sliding member 45 is restored to an upward state, and the first arc face 4513 is tangent to the first right-angled face 4512 of the first right angle 4511. Therefore, when the sliding member 45 enters the KC segment, since the KC segment is upwardly arc-shaped, the two segments of the first arc face 4513 and the two segments of the fourth arc face 4122 enter the arc matching guide stage. In the KC segment, since the first arc face 4513 and the fourth arc face 4122 are both arc faces, and the two first right angles 4511 are both located at the middle positions of the grooves of the second guide segment 412, the orientation of the first guide block 451 can be kept unchanged, that is, the opening of the electroplating unit 1 is always kept in an upward state in the KC segment.

[0079] In one embodiment, referring to Figure 5 The second guide block 452 has two second right angles 4521 symmetrically arranged along the circumference, and the two second right angles 4521 are formed by two second right-angled faces 4522 perpendicularly intersecting, and one second arc face 4523 is connected between the two ends of the two second right angles 4521. The two second right-angled faces 4522 are tangent to the two second arc faces 4523, and the two second arc faces 4523 are symmetrically arranged with the same center and the same diameter as the two first arc faces 4513. The two second right angles 4521 are correspondingly arranged along the stacking direction of the first guide block 451 and the second guide block 452 with the two first arc faces 4513, and the two second arc faces 4523 are correspondingly arranged along the stacking direction of the first guide block 451 and the second guide block 452 with the two first right angles 4511.

[0080] The second circular surface 4523 of the second guide block 452 abuts against the third circular surface 4113 on the first side wall 4111 on the first guide section 411, and the two second right angles 4521 of the second guide block 452 are just along the extension direction of the first guide section 411, that is, the two second right angles 4521 are arranged in the first guide groove of the first guide section 411. On the second guide section 412, the height of the second side wall 4121 is relatively lower than the height of the first side wall 4111, and the height of the second side wall 4121 is just suitable for the thickness of the first guide block 451, so that the two second right angles 4521 can be arranged on the top side of the two second side walls 4121.

[0081] In one embodiment, referring to Figure 6 , the second guide section 412 and the third guide section 413 are provided with a second stop wall 414 at the connection position, and the second stop wall 414 is used to stop the second right angle 4521 to rotate the sliding member 45 by a second preset angle.

[0082] Specifically, referring to Figure 6 , the second guide section 412 has a second side wall 4121, and the third guide section 413 has a third side wall 4131, the height of the third side wall 4131 is higher than the height of the second side wall 4121, and the step between the third side wall 4131 and the second side wall 4121 is the second stop wall 414. As known from the foregoing, on the second guide section 412, the two second right angles 4521 of the second guide block 452 are arranged on the top side of the two second side walls 4121, respectively, so that when the second right angle 4521 slides to the second stop wall 414 at which the second side wall 4121 is connected with the third side wall 4131, the second guide block 452 will rotate clockwise due to the inertia, and rotate by a second preset angle, until the second right angle 4521 slides into the third guide section 413.

[0083] In one embodiment, referring to Figure 6 , the third side wall 4131 of the third guide section 413 is provided with a second clamping groove 4132 and a fifth circular surface 4133, and the second clamping groove 4132 is located at the bottom side of the fifth circular surface 4133. The second right angle surface 4522 of the second right angle 4521 abuts against and slides on the fifth circular surface 4133, and the first right angle 4511 is arranged in the second clamping groove 4132.

[0084] Specifically, when the second guide block 452 rotates clockwise and slides into the third guide section 413, the second straight angle face 4522 of the second straight angle 4521 abuts against the fifth circular arc face 4133 on the third side wall 4131. Since the third guide section 413 is an upwardly extending arc, and the second straight angle face 4522 of the second straight angle 4521 is above the fifth circular arc face 4133, on the CD section, the second straight angle face 4522 of the second straight angle 4521 always abuts against the fifth circular arc face 4133, and the second straight angle face 4522 is just vertically arranged, and at this time, the opening of the electroplating unit 1 on the sliding member 45 is just upwardly directed. In addition, in the third guide section 413, the first straight angle 4511 is partially convex to the third side wall 4131, so the first straight angle 4511 is just limited to slide in the second clamping groove 4132.

[0085] Similarly, in this embodiment, since the acting force of the sliding member 45 is completely borne on the third side wall 4131 on the outer side of the third guide section 413, the third side wall 4131 on the inner side of the third guide section 413 can not be arranged, but a second gap 4134 is formed so that the first straight angle 4511 of the first guide block 451 slides.

[0086] In addition, in this application, although the sliding member 45 has multiple angle rotations, the rotation angle is not large, which does not greatly affect the opening direction of the electroplating unit 1 thereon, and will not cause the material to fall off.

[0087] In one embodiment, please refer to Figure 4 The guide structure 4 further comprises a second guide rail 42 and a third guide rail 43, both of which are straight guide rails, and the second guide rail 42 and the third guide rail 43 are respectively connected to opposite ends of the first guide rail 41, and are respectively tangentially connected with the first guide rail 41; the sliding member 45 is slidably arranged on the second guide rail 42 and the third guide rail 43, and the second guide rail 42 or the third guide rail 43 is provided with a rack 47, and the sliding member 45 further comprises a gear 46 connected with the second guide block 452, and the gear 46 is in meshing transmission with the rack 47 to rotate the sliding member 45 by a third preset angle.

[0088] In this embodiment, the feeding station and the discharging station are arranged on the sliding path of the sliding member 45, specifically, the feeding station is arranged at one end of the second guide rail 42 away from the first guide rail 41, and the discharging station is arranged at one end of the third guide rail 43 away from the first guide rail 41. Therefore, the electroplating unit 1 on the sliding member 45 needs to have the opening facing upward at the feeding station, and needs to keep the opening facing upward during the transportation process through the first guide rail 41, the second guide rail 42 and the third guide rail 43, and needs to have the opening facing downward at the discharging station. Therefore, the rack 47 can be arranged at a position of the third guide rail 43 close to the discharging station. When the sliding member 45 slides to the position of the rack 47 in the state that the electroplating unit 1 has the opening facing upward, the gear 46 on the sliding member 45 meshes with the rack 47. When the sliding member 45 continues to rotate, the gear 46 rotates under the action of the rack 47 and drives the electroplating unit 1 to rotate by 180 degrees, so that the opening of the electroplating unit 1 faces downward and the material is discharged.

[0089] In one embodiment, referring to Figure 4 , the guide structure 4 further comprises a fourth guide rail 44, the fourth guide rail 44 is connected with one end of the second guide rail 42 and the third guide rail 43 away from the first guide rail 41 respectively, the fourth guide rail 44 is in the shape of a semicircular arc, and the sliding member 45 can slide along the fourth guide rail 44; the first guide block 451 is guided and matched with the fourth side wall 441 of the fourth guide rail 44, so that the first guide block 451 rotates with the fourth side wall 441.

[0090] Specifically, the fourth guide rail 44 has two fourth side walls 441 arranged oppositely, both of the two fourth side walls 441 are in the shape of a semicircular arc, the spacing between the two fourth side walls 441 is matched with the diameter of the two first circular surfaces 4513, and the height of the two fourth side walls 441 is matched with the height of the first guide block 451. When the first guide block 451 slides in the fourth guide rail 44, the two second right angles 4521 of the second guide block 452 are respectively arranged on the top side of the fourth side wall 441. During the sliding process of the first guide block 451 in the fourth guide rail 44, the first guide block 451 rotates by 180 degrees with the fourth guide rail 44, so as to rotate the opening of the electroplating unit 1 downward to upward, and then return to the feeding station for feeding.

[0091] In this application, for the electroplating unit 1, it can not only be driven to revolve around by the conveying mechanism 2, but also be driven to rotate by the driving mechanism 3. In order to prevent the revolution and rotation of the electroplating unit 1 from affecting each other, the electroplating unit 1 is designed as follows in this application.

[0092] Please refer to Figure 8 and Figure 9The electroplating unit 1 comprises a drum assembly 001, an electrode shaft 13, two inner rings 11 and a plurality of blades 12. The two inner rings 11 are respectively arranged at opposite ends of the two drum assemblies 001, and the two ends of each blade 12 are respectively mounted on the two inner rings 11. The electrode shaft 13 is mounted in the drum assembly 001, and a plurality of electrodes are distributed on the electrode shaft 13 at intervals. The drum assembly 001 is provided with a first connecting structure 17 for connecting with the conveying mechanism 2. The inner ring 11 is provided with a second connecting structure 18 for connecting with the driving mechanism 3.

[0093] The drum assembly 001 is substantially cylindrical, and the parts to be electroplated are accommodated in the inner cavity of the drum assembly 001. The electrode shaft 13 and the plurality of electrodes are respectively arranged in the inner cavity of the drum assembly 001. A plurality of small holes are distributed on the side wall of the drum assembly 001. The diameter of the small hole is smaller than the size of the part, and the small hole can allow the electroplating solution to enter the inner cavity of the drum assembly 001 and prevent the part from leaking out of the drum assembly 001 through the small hole.

[0094] The two inner rings 11 are respectively arranged at opposite ends of the drum assembly 001, so that each blade 12 is also mounted in the inner cavity of the drum assembly 001. When the driving mechanism 3 drives the inner ring 11 to rotate, the inner ring 11 rotates relative to the drum assembly 001, thereby driving each blade 12 to rotate, and further enabling the parts in the inner cavity of the drum assembly 001 to be stirred, so that the parts continuously tumble and fall to collide with the electrodes. The positive and negative electrodes are connected to form a current, thereby starting to plate a metal layer on the surface of the part.

[0095] When the conveying mechanism 2 drives the drum assembly 001 to move along the runway-shaped track, since the inner ring 11 and the blade 12 are mounted on the drum assembly 001, and there is only relative rotation between the inner ring 11 and the drum assembly 001, without relative movement, the inner ring 11 and the blade 12 also move with the drum assembly 001.

[0096] In one embodiment, referring to Figure 8 and Figure 9 The drum assembly 001 comprises an outer ring 14, a middle ring assembly 15 and a drum 16. The middle ring assembly 15 is rotatably sleeved on the inner ring 11, and the outer ring 14 is rotatably sleeved on the middle ring assembly 15. The axial ends of the drum 16 are respectively mounted on the two middle ring assemblies 15. The first connecting structure 17 is mounted on the outer ring 14, and the third connecting structure 19 for connecting with the guide structure 4 is connected on the middle ring assembly 15.

[0097] The drum 16 is provided with an opening 161 for feeding the parts into the drum 16 or discharging the parts from the drum 16. In order to prevent the parts in the drum 16 from falling off, the opening of the drum 16 needs to be upward as much as possible during the movement of the drum 16.

[0098] The middle ring assembly 15 is rotatably sleeved on the inner ring 11, that is, the middle ring assembly 15 and the inner ring 11 can rotate relative to each other; the outer ring 14 is rotatably sleeved on the middle ring assembly 15, that is, the outer ring 14 and the middle ring assembly 15 can rotate relative to each other. However, the outer ring 14, the middle ring assembly 15 and the inner ring 11 do not move relative to each other. Therefore, when the conveying mechanism 2 drives the outer ring 14 to move, the linear pushing force of the conveying mechanism 2 on the outer ring 14 can be transmitted to the middle ring assembly 15 and the inner ring 11 in turn, so that the conveying mechanism 2 can drive the outer ring 14, the middle ring assembly 15, the inner ring 11, the blade 12 and the roller 16 to move together; when the driving mechanism 3 drives the inner ring 11 to rotate through the second connecting structure 18, since the inner ring 11 and the middle ring assembly 15 are rotatably connected, when the inner ring 11 and the blade 12 rotate, the middle ring assembly 15 and the outer ring 14 do not rotate, so that the rotation of the inner ring 11 does not cause the middle ring assembly 15 to rotate, and thus the opening 161 of the roller 16 does not change in orientation. At the same time, the rotation of the inner ring 11 does not cause the outer ring 14 to rotate, so as not to affect the fixed connection between the outer ring 14 and the conveying mechanism 2. In addition, when the conveying mechanism 2 has a rotary drive on the outer ring 14, in order to prevent the roller 16 from rotating with the outer ring 14 and causing the opening 161 to change in orientation, the middle ring assembly 15 can be guided by the guide structure 4 so that the middle ring assembly 15 remains in a non-rotating state when the outer ring 14 rotates.

[0099] In summary, the electroplating unit 1 of the present application is rotatably connected by the outer ring 14, the middle ring assembly 15 and the inner ring 11, so that the electroplating unit 1 can simultaneously satisfy three kinds of motion without interfering with each other. It can be understood that in other embodiments of the present application, when the roller assembly 001 moves in a straight line, the roller assembly 001 does not rotate during the movement of the roller assembly 001, so the roller assembly 001 can also be a whole structure without being divided into the outer ring 14, the middle ring assembly 15 and the roller 16. Herein, no limitation is made.

[0100] The two outer rings 14 are oppositely arranged and connected by a plurality of connecting rods 110.

[0101] In one embodiment, please refer to Figures 9 to 11The middle ring assembly 15 comprises a mounting ring 151 and a fastening ring 152. The mounting ring 151 comprises a base plate 1511 and a convex ring 1512. Both the base plate 1511 and the convex ring 1512 are annular, and the base plate 1511 and the convex ring 1512 are coaxially connected in steps. The inner diameter of the base plate 1511 is the same as the inner diameter of the convex ring 1512, and the outer diameter of the base plate 1511 is larger than the outer diameter of the convex ring 1512. The base plate 1511 is rotatably arranged between the inner ring 11 and the outer ring 14. The fastening ring 152 is fixed on the base plate 1511, and the fastening ring 152 is sleeved outside the convex ring 1512. The end of the roller 16 abuts between the outer side wall of the convex ring 1512 and the inner side wall of the fastening ring 152, and the outer side wall of the fastening ring 152 abuts with the inner side wall of the outer ring 14. During installation, the fastening ring 152 can be sleeved on the convex ring 1512, then the end of the sleeve 93 is inserted between the fastening ring 152 and the convex ring 1512, and finally the fastening ring 152 is locked on the base plate 1511 by the fastening piece, so that the end of the sleeve 93 can be tightly locked.

[0102] In one embodiment, referring to Figure 8 and Figure 10 The first connecting structure 17 is a transmission wheel. The transmission wheel is arranged outside the inner ring 11 and is coaxially fixedly connected with the inner ring 11. Specifically, the transmission wheel can be a gear, and the transmission wheel is connected with an external gear or a rack to drive the inner ring 11 to rotate. The transmission wheel can also be a chain wheel, and the transmission wheel is connected with an external chain to drive the inner ring 11 to rotate. In addition, the transmission wheel can also be a friction wheel, and an external friction strip is used to drive the transmission wheel to rotate.

[0103] Referring to Figure 8 and Figure 10 The inner ring 11 and the transmission wheel are connected by a connecting cylinder 111. The inner ring 11, the connecting cylinder 111 and the transmission wheel are sequentially fixed and coaxially connected along the axial direction of the inner ring 11. In this embodiment, the connecting cylinder 111 is provided to connect the inner ring 11 and the transmission wheel, and also to provide a certain distance between the inner ring 11 and the transmission wheel, so as to avoid the connection between the transmission wheel and the driving mechanism 3 from interfering with the electroplating unit 1, and also to provide space for the subsequent installation of the sleeve 93.

[0104] In one embodiment, referring to Figures 8 to 11The third connecting structure 19 comprises a transmission shaft 191 and a connecting piece 192. The inner ring 11 has a central hole, the transmission shaft 191 is inserted into the central hole, the transmission shaft 191 is rotationally connected with the inner ring 11, the transmission shaft 191 is used to be connected with the guide structure 4, one end of the connecting piece 192 is connected with the transmission shaft 191, and the other end of the connecting piece 192 is connected with the middle ring assembly 15. When the guide structure 4 drives the transmission shaft 191 to rotate relative to the inner ring 11, the transmission shaft 191 drives the middle ring assembly 15 to rotate through the connecting piece 192, and then the middle ring assembly 15 rotates relative to the inner ring 11 and the outer ring 14.

[0105] Specifically, the transmission shaft 191, the gear 46 and the second guide block 452 are sequentially connected. Since the conveying mechanism 2 drives the outer ring 14 to rotate, the transmission shaft 191 does not rotate through the guide cooperation of the first guide block 451 and the second guide block 452 with the first guide rail 41, that is, the middle ring assembly 15 keeps itself from rotating through relative rotation with the outer ring 14 when the outer ring 14 rotates, and then the opening 161 of the roller 16 is guaranteed to be unchanged.

[0106] Please refer to Figure 7 The first connecting structure 17 is a connecting plate extending axially and outwardly from the outer end surface of the outer ring 14. One end of the connecting plate is fixedly connected with the outer end surface of the outer ring 14, and the other end of the connecting plate is locked to the conveying mechanism 2 through a fastener.

[0107] In an embodiment, please refer to Figure 1 The electroplating device further comprises a power supply structure 5, which is electrically connected with each electroplating unit 1 respectively and is used to supply power to each electroplating unit 1.

[0108] Please refer to Figure 12 and Figure 13 The power supply structure 5 comprises a power supply piece 51, a main conductive piece 52, a plurality of sub-conductive pieces 53 and a plurality of conductive wires 54. The power supply piece 51 is connected with the main conductive piece 52 and supplies power to the main conductive piece 52. The plurality of sub-conductive pieces 53 are arranged around the periphery of the main conductive piece 52 and move around the main conductive piece 52 in sequence. Each sub-conductive piece 53 is electrically connected with the main conductive piece 52 through one conductive wire 54. The conductive wire 54 is elastic, and the length of the conductive wire 54 can change with the distance between the sub-conductive piece 53 and the main conductive piece 52.

[0109] The power supply piece 51 is a distribution box, which is used to supply power to the main conductive piece 52. Of course, in other embodiments of the present application, the power supply piece 51 can also be a power supply board, which is provided with a socket, and the socket is connected with a power supply to supply power to the main conductive piece 52.

[0110] The position of the main conducting member 52 is relatively fixed, that is, the main conducting member 52 does not displace. Each sub-conducting member 53 is arranged in each electroplating unit 1, and the conveying mechanism 2 is used to drive each processing unit 200 to move around the main conducting member 52, so as to drive each sub-conducting member 53 to move around the main conducting member 52 in turn.

[0111] The wire 54 is elastic, and can not only realize electrical connection, but also realize electrical connection between two objects with changing distance. The wire 54 can include a copper wire and an insulating material wrapped outside the copper wire. The insulating material is spirally twisted, for example, like a telephone line, so that the wire 54 is elastic.

[0112] When power supply is performed, the main conducting member 52 is first powered by the power supply member 51, and the main conducting member 52 powers each sub-conducting member 53 through each wire 54 in turn. When each sub-conducting member 53 moves around the main conducting member 52, the distance between the sub-conducting member 53 and the main conducting member 52 changes with the movement of the sub-conducting member 53, and the length of the wire 54 changes with the change of the distance between the sub-conducting member 53 and the main conducting member 52, so that the main conducting member 52 can always power each sub-conducting member 53, and the power supply is stable.

[0113] In one embodiment, please refer to Figure 14 The length extension direction of the main conducting member 52 is the same as the length extension direction of each sub-conducting member 53, that is, during the movement of each sub-conducting member 53, the main conducting member 52 and each sub-conducting member 53 are in a parallel state in three-dimensional space.

[0114] In one embodiment, please refer to Figure 12 The power supply structure 5 includes a plurality of wire groups 01, each wire group 01 is arranged in turn along the length extension direction of the main conducting member 52, and the wire group 01 includes at least one wire 54. For example, as Figure 12The power supply structure 5 includes 12 sub-conducting components 53 and 12 wires 54. The 12 wires 54 are divided into 6 groups of wires 01, each group of wires 01 including two wires 54. The 6 groups of wires 01 are arranged at intervals along the length of the main conductive component 52, that is, 6 mounting positions are defined on the main conductive component 52 along its length. The 6 mounting positions are arranged at intervals, and the 6 groups of wires 01 are installed at these 6 mounting positions, thus ensuring that the groups of wires 01 are staggered along the length of the main conductive component 52, avoiding structural interference between the groups of wires 01. Furthermore, by setting a group of wires 01 at each length position of the main conductive component 52, when the number of each group of wires 01 is greater than one, different wires 54 can apply tension to the main conductive component 52 in different directions to maintain the force balance of the main conductive component 52. Understandably, in other embodiments of this application, the number of wires 54 in each group of wires 01 may be one, three or more. When each group of wires 01 includes one wire 54, that is, each wire 54 is staggered along the length extension direction of the main conductive member 52. When each group of wires 01 includes three or more wires 54, the number of wire groups 01 can be reduced, and the length of the main conductive member 52 and the branch conductive member 53 can also be reduced, thereby reducing the space occupied by the entire power supply structure 5 along the length direction of the main conductive member 52. This is not a unique limitation.

[0115] In one embodiment, see Figure 12 Each wire group 01 includes at least two wires 54. In the same wire group 01, the at least two wires 54 are connected to the main conductive component 52 at the same length position of the main conductive component 52, and the at least two wires 54 are connected to different positions along the circumference of the main conductive component 52. The at least two wires 54 are equally spaced along the circumference of the main conductive component 52. In this embodiment, by setting the at least two wires 54 located at the same length position of the main conductive component 52 at equal intervals along the circumference of the main conductive component 52, the wires 54 in the same wire group 01 are prevented from tangling with each other, and the connectors on the main conductive component 52 used to connect the wires 54 are also prevented from interfering with each other. By connecting each wire 54 in the same wire group 01 to different positions along the circumference of the main conductive component 52, the force exerted by each wire 54 on the main conductive component 52 is evenly distributed along the circumference, and the forces cancel each other out, thereby balancing the forces on the main conductive component 52 and maintaining its positional stability.

[0116] Optionally, please refer to Figure 12, each sub-conductive member 53 moves along a runway track around the main-conductive member 52, and during the movement of each sub-conductive member 53, two sub-conductive members 53 are always arranged in a center-symmetrical manner with respect to the center line of the main-conductive member 52. Therefore, in this embodiment, each group of wire sets 01 includes two wires 54, and the two wires 54 are connected to different positions of the main-conductive member 52 in the circumferential direction, respectively.

[0117] In one embodiment, please refer to Figure 12 , the connection positions of each wire 54 on the main-conductive member 52 are equally spaced in the circumferential direction of the main-conductive member 52, for example Figure 13 , 12 wires 54 are staggered in the circumferential direction, so that the wires 54 are connected to the main-conductive member 52 in a straight line without detours.

[0118] In one embodiment, the main-conductive member 52 is arranged to rotate around the center line of the main-conductive member 52. For example, please refer to Figure 13 , the main-conductive member 52 is rotatably arranged on the frame 6. Specifically, two opposite positions on the frame 6 are provided with through holes, and opposite ends of the main-conductive member 52 in the length direction are rotatably arranged in the two through holes, respectively. When each sub-conductive member 53 is moved along a runway track under the driving of the external conveying mechanism, each sub-conductive member 53 pulls each wire 54 in the circumferential direction, thereby driving the main-conductive member 52 to rotate around the center line thereof. In this embodiment, the main-conductive member 52 is arranged to rotate around the center line thereof, so that when each sub-conductive member 53 moves along a runway track, each wire 54 will also be moved along. In order to avoid the entanglement of each wire 54 on the main-conductive member 52 and to avoid the entanglement of each wire 54 with each other, the main-conductive member 52 is arranged to rotate around the center line thereof.

[0119] In one embodiment, please refer to Figure 13 , the main-conductive member 52 includes a copper rod 521 and an insulating sleeve 522 covering the surface of the copper rod 521, and the copper rod 521 is provided with a first connecting terminal 523 for connecting with the wire 54, and the first connecting terminal 523 penetrates through the insulating sleeve 522 to connect with the wire 54. In this embodiment, the copper rod 521 is arranged to have good electrical conductivity and high structural strength; the first connecting terminal 523 is arranged to realize the connection between the copper rod 521 and the wire 54; and the insulating sleeve 522 is arranged to insulate the copper rod 521 from the outside, so that the main-conductive member 52 can be applied in a conductor environment, for example, the main-conductive member 52 is arranged in an electroplating liquid environment, that is, the copper rod 521 can supply power to each electroplating unit 1 in the electroplating liquid.

[0120] In one embodiment, please refer to Figure 14The main conducting member 52 further comprises a plurality of sealing sleeves 524, which are respectively sleeved on the insulating sleeve 522 at different positions in the axial direction. The insulating sleeve 522 is provided with a through slot at a position corresponding to the first connecting terminal 523, and the sealing sleeve 524 is provided with a connecting hole at a position corresponding to the through slot. One end of the first connecting terminal 523 is connected with the copper bar 521, and the other end of the first connecting terminal 523 is sequentially penetrated through the through slot and the connecting hole and then extends out of the sealing sleeve 524. The first connecting terminal 523 and the sealing sleeve 524 are sealed and connected by a first sealing ring.

[0121] In one embodiment, referring to ​ The sub-conducting member 53 comprises an electrode shaft 531, a second connecting terminal 532 and a plurality of positive electrodes 533. The length extension direction of the electrode shaft 531 is the same as that of the copper bar 521, and the electrode shaft 531 is made of a conductive material, for example, copper. The second connecting terminal 532 is arranged on the electrode shaft 531 and is used for electrically connecting with the wire 54. The plurality of positive electrodes 533 are distributed on the electrode shaft 531 along the length extension direction of the electrode shaft 531. In this embodiment, by distributing the plurality of positive electrodes 533 on the electrode shaft 531, the probability of the parts colliding with the electrode during the electroplating is improved, and the uniformity of the part coating is further improved. The electrode shaft 531 is the electrode shaft 13 in the electroplating unit 1.

[0122] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
