It is understood that in other embodiments of the present application, the two side barrel plating driving mechanisms 3 can be synchronously connected by the synchronizing member if the structure allows, so that the number and cost of one rotary driving member 33 can be saved.

In another embodiment of the present application, since the third sprocket 34 and the first sprocket 221 are coaxially disposed and are all sleeved on the first connecting shaft 25, the third sprocket 34 and the first connecting shaft 25 can be fixedly connected without the rotation driving member 33, and the third sprocket 34 is driven to rotate by the first connecting shaft 25, so as to drive the double-row chain to move, and the electroplating unit 1 can be driven to move and rotate by one conveying driving member 21, so as to save the number and cost of the driving members.

In one embodiment, the conveying mechanism 2 is vertically arranged and is used for driving each electroplating unit 1 to move along a vertically arranged track of a track type. For the loading and unloading of the electroplating unit 1, an opening is generally formed in the electroplating unit 1, and the electroplating unit 1 is loaded or unloaded through the opening. Because the electroplating unit 1 can move along with the first chain, the electroplating unit 1 moves to the position of the bottom arc or the top arc of the first chain, the electroplating unit 1 rotates, the rotation of the electroplating unit 1 can cause the opening of the electroplating unit 1 to change, for example, the bottom arc of the first chain can be changed by 180 degrees, the electroplating unit 1 can also rotate by 180 degrees, if the opening is upward before passing through the bottom arc, the opening can be downward after passing through the bottom arc, and the part can fall out from the opening.

In this case, it is conventional to provide a cover at the opening, cover the opening with the cover to prevent the parts from falling out, and then open the cover at the time of discharge. However, since all the plating units 1 are driven to roll by the driving mechanism 3 while moving along with the first chain, the cover is disposed at the opening, and the structure for automatically opening and closing the cover is complicated, which affects the overall operation of the plating units 1.

To this end, this application has set up guide structure 4, and guide structure 4 is connected between frame 6 and electroplating unit 1 to be used for leading electroplating unit 1, so that electroplating unit 1's opening orientation predetermines the direction. Specifically, this guide structure 4 makes electroplating unit 1 can not take place the rotation when the bottom circular arc of first chain to guarantee that electroplating unit 1's opening is up all the time, and then prevent that the part from dropping out when electroplating unit 1 through the bottom circular arc of first chain.

Referring to fig. 4 and 5, the guiding structure 4 includes a first guiding rail 41 and a sliding member 45, a first guiding groove with a semicircular arc shape is formed in the first guiding rail 41, and the sliding member 45 is slidably disposed in the first guiding groove; the slider 45 includes a first guide block 451 and a second guide block 452 stacked on each other; during the sliding process of the sliding member 45 in the first guiding groove, the first guiding block 451 and the second guiding block 452 alternately form a rotation limit fit with different depth positions on the side wall of the first guiding rail, so as to adjust the sliding orientation of the sliding member 45 in the first guiding rail.

It should be noted that, the first guide block 451 and the second guide block 452 are stacked, and when the sliding member 45 is slidably disposed 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 than the second guide block 452 for the first guide groove. Similarly, when engaged with the side wall of the first guide groove, the first guide block 451 is engaged with the side wall of the first guide groove at a position near the bottom, and the second guide block 452 is engaged with the side wall of the first guide groove at a position near the top.

Furthermore, during the sliding of the sliding member 45 in the first guiding groove, the first guiding block 451 and the second guiding block 452 alternately form a rotation-limiting fit with the side wall of the first guiding rail, that is, when the sliding member 45 slides to a different section, it is possible to form a rotation-limiting fit with the side wall of the first guiding rail 41 through the first guiding block 451, and it is also possible to form a guiding fit with the side wall of the first guiding rail 41 through the second guiding block 452. Since the first guide groove is formed in a semicircular arc shape, the side wall of the first guide rail 41 also extends in a semicircular arc shape, and the slider 45 cannot be always engaged with the side wall of the first guide rail 41 in the sliding process, the slider 45 is divided into the first guide block 451 and the second guide block 452 which are stacked, and the first guide block 451 and the second guide block 452 are engaged with the side wall at different positions, so that the orientation of the slider 45 is substantially unchanged. The present application generally counteracts the change in orientation of the slider 45 due to the presence of different road segments by different guiding fits over different road segments. For example, in one of the sections, the first guide block 451 and the side wall of the first guide rail 41 are mutually guided and matched to enable the sliding member 45 to deflect clockwise, and in the other section, the second guide block 452 and the side wall of the first guide rail 41 are mutually guided and matched to enable the sliding member 45 to deflect anticlockwise, so that after sliding in the whole first guide rail 41, the overall orientation of the sliding member 45 is not changed too much, and further, the opening of the electroplating unit 1 on the sliding member 45 is not downward to pour out the material.

In one embodiment, referring to fig. 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 two opposite ends of the second guide section 412. Specifically, referring to fig. 5, the second guiding section 412 is a BC section, and the first guiding section 411 and the second guiding section 412 are an AB section and a CD section, respectively.

The second guide block 452 can respectively form a rotation limit fit with the first side wall 4111 of the first guide section 411 and the third side wall 4131 of the third guide section 413; the first guide block 451 forms a rotational limit fit with the second side wall 4121 of the second guide section 412. Specifically, taking the sliding member 45 sliding in the first guiding rail 41 counterclockwise from left to right as an example, the sliding member 45 slides into the first guiding section 411, and at this time, the second guiding block 452 forms a rotation limit fit with the first side wall 4111 of the first guiding section 411, so that the orientation of the sliding member 45 in the first guiding section 411 is substantially kept unchanged; then, the sliding member 45 slides into the second guiding section 412, and when the second guiding block 452 fails to engage with the second side wall 4121 of the second guiding section 412, the first guiding block 451 forms a rotational limit engagement with the second side wall 4121 of the second guiding section 412, so that the orientation of the sliding member 45 does not change too much; when the slider 45 slides to the third guide section 413, since the arc of the third guide section 413 is symmetrically arranged with the arc of the first guide section 411, the orientation of the slider 45 can be maintained substantially unchanged by the second guide block 452 cooperating with the third side wall 4131 of the third guide section 413 through the first guide section 411, the second guide section 412 and the third guide section 413.

In one embodiment, referring to fig. 5 to 7, a surface of the first guide block 451 has two first straight angles 4511 symmetrically arranged along the circumferential direction, the second guide block 452 has two second circular arc surfaces 4523 symmetrically arranged along the circumferential direction, and the two first straight angles 4511 and the two second circular arc surfaces 4523 are arranged in a one-to-one correspondence manner along the stacking direction of the first guide block 451 and the second guide block 452. The first guide section 411 has two first side walls 4111 arranged oppositely, a first clamping groove 4112 and a third arc surface 4113 are formed on the first side wall 4111 located at the outer side, and the first clamping groove 4112 is located at the bottom side of the third arc surface 4113; the first side wall 4111 of the first guide section 411 on the inner side forms a first cutout 4115 by removing material, i.e., the first guide section 411 does not form a side wall close to the inner side.

When the sliding member 45 is slidably disposed on the first guiding segment 411 in the two first straight angles 4511 respectively located at the lower left corner and the upper right corner, the opening of the electroplating unit 1 mounted on the sliding member 45 is just upward. When the slider 45 slides downwards, the first straight angle 4511 located at the lower left corner is vertically clamped downwards by inertia into the first clamping groove 4112 of the first side wall 4111 at the outer side, and the second arc surface 4523 in the second guide block 452 is just abutted and matched with the third arc surface 4113, so that the slider 45 can be prevented from rotating in the sliding process. Further, since the slider 45 slides downward, the point of force of the slider 45 is on the first side wall 4111 located on the outer side, and therefore the first side wall 4111 on the inner side may not be provided. Meanwhile, due to the arrangement of the first notch 4115, the first straight corner 4511 located at the upper right corner can slide along the first notch 4115, without structural interference with the first guide section 411. It is understood that in other embodiments of the present application, the two first side walls 4111 of the first guide section 411 may be configured identically, and are not limited thereto.

In one embodiment, referring to fig. 6, the first locking groove 4112 extends along a length of the first guiding segment 411, the first locking groove 4112 has a first stopping wall 4114 close to the second guiding segment 412, and the first stopping wall 4114 is used for stopping the first straight angle 4511 to rotate the sliding member 45 by a first preset angle. Specifically, first draw-in groove 4112 is the arc wall on the first lateral wall 4111 of the position outside of offering first direction section 411, and first draw-in groove 4112 runs through the inside and outside both sides of first lateral wall 4111, and first backstop wall 4114 is the terminal lateral wall of first draw-in groove 4112. When the slider 45 slides along the first guide segment 411, the first straight corner 4511 located at the lower left corner slides along the first clamping slot 4112 until the first straight corner 4511 abuts against the first stopping wall 4114, due to inertia, the first straight corner 4511 rotates counterclockwise due to the stopping of the first stopping wall 4114 until the first straight corner 4511 slides out of the first clamping slot 4112, and a right-angled surface of the first straight corner 4511 abuts against the second side wall 4121, which is located at the outer side, of the second guide segment 412, so that the slider 45 slides into the second guide segment 412 stably.

In this embodiment, since the first right angle 4511 slides to the lowest end in the first engaging groove 4112, the first guiding rail 41 starts to turn, and the direction of the sliding member 45 cannot be ensured by the limit between the first right angle 4511 and the first engaging groove 4112. It is now necessary to cooperate with the second guide section 412 by other positions of the slider 45 to achieve that the orientation of the slider 45 is kept within a certain range. Since the slide 45 cannot stably slide into the second guide section 412 in the current state, the slide 45 can be pushed to rotate by the arrangement of the first stopping wall 4114, so that the slide 45 can just slide into the second guide section 412.

In one embodiment, referring to fig. 5 and 7, the first guide block 451 has two first straight angles 4511 symmetrically arranged along the circumferential direction, a first arc surface 4513 is connected between two ends of the two first straight angles 4511, and the two first arc surfaces 4513 are concentrically and symmetrically arranged; the two second side walls 4121 of the second guide segment 412 are respectively provided with a fourth arc surface 4122, and the distance between the two fourth arc surfaces 4122 is matched with the diameter of the two first arc surfaces 4513; in second guide section 412, first arc surface 4513 and first straight angle 4511 alternately engage in abutment with fourth arc surface 4122.

Specifically, the first straight angle 4511 is formed by intersecting two first straight planes 4512 perpendicular to each other, the two first straight planes 4512 of the first straight angle 4511 are respectively arranged in tangent with two first arc planes 4513, and the diameter of the first arc planes 4513 is adapted to the distance between the inner and outer second sidewalls 4121 of the second guide segment 412.

The second guide segment 412 is specifically divided into two parts, as shown in fig. 5, which are respectively a BK segment and a CK segment, for the BK segment, the rotated slider 45 is stopped by the first stopping wall 4114, the two opposite first straight-angle surfaces 4512 of the two first straight-angle surfaces 4511 slide with the two fourth arc surfaces 4122 respectively, since in the BK segment, the slider 45 slides down along the arc, while the fourth arc surface 4122 of the second guide segment 412 located below has an upward stopping force on the first straight-angle surface 4511, so that the first straight-angle surface 4512 of the first straight-angle surface 4511 is always in a fit with the fourth arc surface 4122, that is, the slider 45 angularly rotates along with the arc of the fourth arc surface 4122, a position of sliding to K is made, the first guide block 451 slides to the two opposite first straight-angle surfaces 4512 of the first straight-angle surfaces 4511, and is in a horizontal state, at this time, the opening of the electroplating unit 1 on the slider 45 is restored to an upward state, and the first straight-angle surface 4513 slides to the first straight-angle surface 4511 to the second straight-angle surface 4511 and the opening of the second arc surface 4512 is kept in a horizontal state when the slider 12 of the first guide segment KC segment is in the second arc surface 4122, the second arc surface 4113 is in a state, the middle guide segment KC segment, so that the electroplating unit is kept in a state, and the middle guide segment 4513 is kept tangential state, and the second arc surface 4, the second arc surface 4513 is kept in a state.

In one embodiment, referring to fig. 5, the second guide block 452 has two second right angles 4521 symmetrically arranged along the circumferential direction, the second right angle 4521 is formed by perpendicularly intersecting two second right angle surfaces 4522, a second arc surface 4523 is connected between two ends of the two second right angles 4521, the two second right angle surfaces 4522 are respectively connected to the two second arc surfaces 4523 in a tangential manner, the two second arc surfaces 4523 are concentric and symmetrically arranged, and the diameters of the two second arc surfaces 4523 are the same as the diameters of the two first arc surfaces 4513; two second right angles 4521 are respectively arranged corresponding to the two first arc surfaces 4513 in the stacking direction of the first guide block 451 and the second guide block 452, and two second arc surfaces 4523 are respectively arranged corresponding to the two first right angles 4511 in the stacking direction of the first guide block 451 and the second guide block 452.

When the second arc surface 4523 of the second guide block 452 abuts against the third arc surface 4113 of the first side wall 4111 on the first guide segment 411, two second right angles 4521 of the second guide block 452 are exactly along the extending direction of the first guide segment 411, that is, two second right angles 4521 are disposed in the first guide groove of the first guide segment 411. On the second guide section 412, since the height of the second side wall 4121 is relatively short with respect to the height of the first side wall 4111, the height of the second side wall 4121 is just matched with the thickness of the first guide block 451, and two second right angles 4521 can be just slidably arranged on the top side surfaces of the two second side walls 4121.

In one embodiment, referring to fig. 6, a second stopping wall 414 is disposed at a connection point of the second guiding segment 412 and the third guiding segment 413, and the second stopping wall 414 is used for forming a stop for the second right angle 4521 so as to rotate the sliding member 45 by a second predetermined angle.

Specifically, referring to fig. 6, the second guiding section 412 has a second side wall 4121, the third guiding section 413 has a third side wall 4131, the height of the third side wall 4131 is higher than that of the second side wall 4121, and the step formed between the third side wall 4131 and the second side wall 4121 is the second stopping wall 414. As can be seen from the foregoing description, in the second guide section 412, the two second right angles 4521 of the second guide block 452 are slidably disposed on the top side surfaces of the two second side walls 4121, respectively, so that when the second right angle 4521 slides to the second stop wall 414 where the second side wall 4121 is connected to the third side wall 4131, due to inertia, the second guide block 452 rotates clockwise by the stop of the second stop wall 414, and rotates clockwise by a second predetermined angle until the second right angle 4521 slides into the third guide section 413.

In one embodiment, referring to fig. 6, the third side wall 4131 of the third guiding segment 413 is formed with a second locking groove 4132 and a fifth arc surface 4133, and the second locking groove 4132 is located at a bottom side of the fifth arc surface 4133. The second right-angle surface 4522 of the second right-angle 4521 abuts against and slides on the fifth arc surface 4133, and the first right-angle 4511 is limited in the second clamping groove 4132 in a sliding manner.

Specifically, after the second guide block 452 rotates clockwise to slide into the third guide segment 413, the second right-angle surface 4522 of the second right angle 4521 abuts against the fifth circular arc surface 4133 on the third side wall 4131, and since the third guide segment 413 is in an upward extending arc shape, the second right-angle surface 4522 of the second right angle 4521 is located above the fifth circular arc surface 4133, on the CD segment, the second right-angle surface 4522 of the second right angle 4521 always abuts against the fifth circular arc surface 4133, the slide is made to the point D, the second right-angle surface 4522 is arranged vertically, and the opening of the electroplating unit 1 located on the slide 45 faces upward. In addition, in the third guide segment 413, the first straight corner 4511 is partially protruded toward the third side wall 4131, so that the first straight corner 4511 is just slidingly restrained in the second locking groove 4132.

Also, in this embodiment, since the force of the slider 45 is completely carried on the outer third side wall 4131 of the third guide segment 413, the inner third side wall 4131 of the third guide segment 413 may not be provided, but a second notch 4134 is formed to facilitate the sliding of the first straight angle 4511 of the first guide block 451.

In addition, in the present application, although the sliding member 45 is angularly rotated a plurality of times, the angle of rotation is not so large as to affect the opening orientation of the plating unit 1 thereon too much, and further, the material is not dropped.

In one embodiment, referring to fig. 4, the guiding structure 4 further includes a second guiding rail 42 and a third guiding rail 43, both the second guiding rail 42 and the third guiding rail 43 are linear guiding rails, the second guiding rail 42 and the third guiding rail 43 are respectively connected to two opposite ends of the first guiding rail 41, and the second guiding rail 42 and the third guiding rail 43 are respectively connected to the first guiding rail 41 in a tangent manner; the sliding part 45 can be slidably arranged on the second guide rail 42 and the third guide rail 43, a rack 47 is arranged on the second guide rail 42 or the third guide rail 43, the sliding part 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 enable the sliding part 45 to rotate by a third preset angle.

In this embodiment, a feeding station and a discharging station are disposed on a sliding path of the sliding member 45, specifically, the feeding station is disposed at an end of the second guide rail 42 away from the first guide rail 41, and the discharging station is disposed at an end of the third guide rail 43 away from the first guide rail 41, so that the electroplating unit 1 on the sliding member 45 needs to have an upward opening in the feeding station, needs to have an upward opening in a transportation process through the first guide rail 41, the second guide rail 42, and the third guide rail 43, and needs to have a downward opening in the discharging station, so that the rack 47 can be disposed at a position of the third guide rail 43 close to the discharging station, when the sliding member 45 slides to the rack 47 in a state that the opening of the electroplating unit 1 faces upward, the gear 46 on the sliding member 45 is engaged with the rack 47, and 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 180 degrees, so that the opening of the electroplating unit 1 faces downward, and the material is poured out.

In one embodiment, referring to fig. 4, the guiding structure 4 further includes a fourth guiding rail 44, the fourth guiding rail 44 is connected to the ends of the second guiding rail 42 and the third guiding rail 43 away from the first guiding rail 41, respectively, the fourth guiding rail 44 is in a semi-circular arc shape, and the sliding member 45 can slide along the fourth guiding rail 44; the first guide block 451 is in guiding engagement with the fourth side wall 441 of the fourth guide rail 44 such that the first guide block 451 rotates with the fourth side wall 441.

Specifically, the fourth guide rail 44 has two fourth side walls 441 arranged oppositely, each of the two fourth side walls 441 is in a semicircular arc shape, a distance between the two fourth side walls 441 is matched with diameters of the two first arc surfaces 4513, heights of the two fourth side walls 441 are matched with a height of the first guide block 451, and 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 slidably disposed on top sides of the fourth side walls 441. During the sliding process of the first guide block 451 in the fourth guide rail 44, the first guide block 451 rotates 180 degrees along with the fourth guide rail 44, so that the opening of the electroplating unit 1 rotates downwards to the opening upwards, and then returns to the loading station for loading.

In the present application, the plating unit 1 can be rotated by the driving mechanism 3 as well as being rotated along the first chain by the conveying mechanism 2, and in order to prevent the rotation and the revolution of the plating unit 1 from affecting each other, the plating unit 1 is designed as follows.

Referring to fig. 8 and 9, the electroplating unit 1 includes a roller assembly 001, an electrode shaft 13, two inner rings 11, and a plurality of blades 12. Wherein, the two inner rings 11 are respectively and rotatably arranged at two opposite ends of the two roller assemblies 001, and two ends of each blade 12 are respectively arranged on the two inner rings 11; electrode shaft 13 is installed in drum assembly 001, and the last electrode that distributes of electrode shaft 13 has a plurality of intervals to set up, is equipped with the first connection structure 17 that is used for being connected with conveying mechanism 2 on drum assembly 001, is connected with the second connection structure 18 that is used for being connected with actuating mechanism 3 on the inner ring 11.

The roller assembly 001 is roughly cylindrical, a part to be electroplated is accommodated in an inner cavity of the roller assembly 001, the electrode shaft 13 and the electrodes are respectively arranged in the inner cavity of the roller assembly 001, small holes are distributed in the side wall of the roller assembly 001, the diameter of each small hole is smaller than the size of the part, plating solution can enter the inner cavity of the roller assembly 001 through the small holes, and the part can be prevented from leaking out of the roller assembly 001 from the small holes.

Two inner rings 11 are rotatably provided at opposite ends of the drum assembly 001, respectively, so that each blade 12 is also installed 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 roller component 001 to drive the blades 12 to rotate, so that parts in the inner cavity of the roller component 001 can be rolled, the parts are continuously rolled and fall to collide with the electrodes, the cathode and the anode are conducted to form current, and then a metal layer is plated on the surface of the parts.

When the conveying mechanism 2 drives the roller assembly 001 to move along the track-type track, the inner ring 11 and the blades 12 are both mounted on the roller assembly 001, and only relatively rotate and do not relatively move between the inner ring 11 and the roller assembly 001, so that the inner ring 11 and the blades 12 also move along with the roller assembly 001.

In one embodiment, referring to fig. 8 and 9, the roller assembly 001 includes an outer ring 14, a middle ring assembly 15 and a roller 16; the middle ring component 15 is rotationally sleeved on the inner ring 11, and the outer ring 14 is rotationally sleeved on the middle ring component 15; the two axial ends of the roller 16 are respectively installed on the two middle ring assemblies 15, the first connecting structure 17 is installed 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.

Wherein, the drum 16 is provided with an opening 161, the opening 161 is used for feeding materials into the drum 16 or feeding parts into the drum 16, and in order to ensure that the parts in the drum 16 do not fall, the opening of the drum 16 needs to be ensured to face upwards as much as possible during the movement of the drum 16.

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 with 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 driving force of the conveying mechanism 2 on the outer ring 14 can be sequentially transmitted to the middle ring assembly 15 and the inner ring 11, and then the conveying mechanism 2 can drive the outer ring 14, the middle ring assembly 15, the inner ring 11, the blades 12, the roller 16 and the like to move together; when the driving mechanism 3 drives the inner ring 11 to rotate through the second connecting structure 18, because the inner ring 11 is rotationally connected with the middle ring assembly 15, when the inner ring 11 and the blades 12 rotate, the middle ring assembly 15 and the outer ring 14 do not rotate, and the rotation of the inner ring 11 does not cause the middle ring assembly 15 to rotate, so that the orientation of the opening 161 of the roller 16 is not changed; at the same time, the rotation of the inner ring 11 does not cause the outer ring 14 to rotate, and therefore the fixed connection of the outer ring 14 to the conveying mechanism 2 is not affected. Further, when the conveying mechanism 2 has a rotational drive to the outer ring 14, in order to prevent the roller 16 from following the rotation of the outer ring 14 to cause the orientation of the opening 161 to change, the centering ring assembly 15 may be guided by the guide structure 4 so that the centering ring assembly 15 is kept in a non-rotating state while the outer ring 14 rotates.

To sum up, the electroplating unit 1 of the present application is connected by the rotation of the outer ring 14, the middle ring assembly 15 and the inner ring 11, so that the electroplating unit 1 can simultaneously satisfy three motions without interfering with each other. It is understood that in other embodiments of the present application, when the roller assembly 001 moves along a straight line, the roller assembly 001 does not rotate during the movement of the roller assembly 001, and the roller assembly 001 may also be a unitary structure, and need not be divided into three parts, i.e., the outer ring 14, the middle ring assembly 15 and the roller 16, which is not limited herein.

The two outer rings 14 are oppositely disposed and connected by a plurality of connecting rods 110.

The base plate 1511 is rotatably disposed between the inner ring 11 and the outer ring 14, the fastening ring 152 is fixed on the base plate 1511, the fastening ring 152 is sleeved outside the convex ring 1512, the end of the roller 16 abuts between the outer sidewall of the convex ring 1512 and the inner sidewall of the fastening ring 152, and the outer sidewall of the fastening ring 152 abuts against the inner sidewall of the outer ring 14. During installation, the fastening ring 152 can be sleeved on the convex ring 1512, the end portion 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 through the fastener, so that the end portion of the sleeve 93 can be tightly locked.

In an embodiment, referring to fig. 8 and fig. 10, the first connecting structure 17 is a driving wheel, the driving wheel is disposed on the outer side of the inner ring 11, and the driving wheel is coaxially and fixedly connected with the inner ring 11. Specifically, the driving wheel may be a gear, and the driving wheel is engaged with an external gear or a rack, so as to drive the inner ring 11 to rotate. The driving wheel can also be a chain wheel, and the driving wheel is meshed with an external chain to drive the inner ring 11 to rotate. In addition, the transmission wheel can also be a friction wheel, and the transmission wheel is driven to rotate by an external friction strip.

Referring to fig. 8 and 10, a connecting cylinder 111 is connected between the inner ring 11 and the driving wheel, and the inner ring 11, the connecting cylinder 111 and the driving wheel are sequentially fixed and coaxially connected along the axial direction of the inner ring 11. In the embodiment, the connecting cylinder 111 is arranged, so that the inner ring 11 is connected with the driving wheel, and a certain distance is reserved between the inner ring 11 and the driving wheel, thereby preventing the driving wheel and the driving mechanism 3 from being connected to generate structural interference with the electroplating unit 1, and providing a space for the subsequent installation of the sleeve 93.

In one embodiment, referring to fig. 8 to 11, the third connecting structure 19 includes a transmission shaft 191 and a connecting member 192; the inner ring 11 is provided with a central hole, a transmission shaft 191 is inserted into the central hole, the transmission shaft 191 is rotatably connected with the inner ring 11, the transmission shaft 191 is used for being connected with the guide structure 4, one end of a 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 component 15. When the guiding 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 member 192, so that the middle ring assembly 15 rotates relative to the inner ring 11 and the outer ring 14.

Specifically, the transmission shaft 191, the gear 46 and the second guide block 452 are sequentially connected, and since the conveying mechanism 2 drives the outer ring 14 to rotate, the transmission shaft 191 does not rotate through the guiding cooperation between the first guide block 451 and the second guide block 452 and the first guide rail 41, that is, when the outer ring 14 rotates, the middle ring component 15 rotates relative to the outer ring 14 and keeps itself not rotating, so as to ensure that the direction of the opening 161 of the roller 16 is unchanged.

Referring to fig. 7, the first connecting structure 17 is a connecting plate extending axially outward 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 by a fastener.

In one embodiment, referring to fig. 1, the electroplating apparatus further includes a power supply structure 5, and the power supply structure 5 is electrically connected to each electroplating unit 1 and is used for supplying power to each electroplating unit 1.

Referring to fig. 12 and 13, the power supply structure 5 includes a power supply element 51, a main conductive element 52, a plurality of conductive elements 53 and a plurality of wires 54; the power supply member 51 is connected with the main conductive member 52 and supplies power to the main conductive member 52; a plurality of sub-conductive members 53 surrounding the main conductive member 52 and sequentially moving around the main conductive member 52, each sub-conductive member 53 being electrically connected to the main conductive member 52 by a conductive wire 54; the conductive wire 54 has elasticity, and the length of the conductive wire 54 can be changed as the distance from the conductive member 53 to the main conductive member 52 is changed.

The power supply 51 is a distribution box, and the distribution box is used for supplying power to the main conductive part 52. Of course, in other embodiments of the present application, the power supply member 51 may also be a power supply board, and a socket is disposed on the power supply board, and is connected to the power supply through the socket, so as to supply power to the main conductive member 52.

The position of the main conductive member 52 is relatively fixed, i.e., the main conductive member 52 is not displaced. The conductive component parts 53 are respectively arranged in the electroplating units 1, and the conveying mechanism 2 is used for driving the processing units 200 to move around the main conductive component 52, so that the conductive component parts 53 are sequentially driven to move around the main conductive component 52.

The wires 54 are elastic, which means that the wires 54 can not only realize the electrical connection, but also realize the electrical connection between the two with the constantly changing spacing. The wires 54 may include copper wires and an insulating material wrapped around the copper wires, the insulating material being helically wound, such as a telephone wire, to provide flexibility to the wires 54.

When power is supplied, firstly, the power supply part 51 is used as a main conductive part 52, and the main conductive part 52 supplies power to the sub-conductive parts 53 through the leads 54 one by one; when the sub-conductive members 53 move around the main conductive member 52, the distance between the sub-conductive members 53 and the main conductive member 52 changes with the movement of the sub-conductive members 53, and the length of the conductive wire 54 changes with the change in the distance between the sub-conductive members 53 and the main conductive member 52, so that the main conductive member 52 can always supply power to the sub-conductive members 53 with stable power supply.

In one embodiment, referring to fig. 14, the length extending direction of the main conductive member 52 is the same as the length extending direction of each sub-conductive member 53, that is, during the movement of each sub-conductive member 53, the main conductive member 52 and each sub-conductive member 53 are in a state of being parallel to each other in three-dimensional space.

In one embodiment, referring to fig. 12, the power supply structure 5 includes a plurality of sets of wires 01, each set of wires 01 is disposed at intervals along the length of the main conductive member 52, and each set of wires 01 includes at least one wire 54. For example, as shown in fig. 12, the power supply structure 5 includes 12

conductive component members

53 and 12 conductive wires 54, the 12 conductive wires 54 are divided into 6 groups of conductive wire groups 01, and each group of conductive wire groups 01 includes two conductive wires 54. The 6 groups of lead groups 01 are sequentially arranged at intervals along the length extending direction of the main conductive member 52, that is, 6 installation positions are divided on the main conductive member 52 along the length extending direction of the main conductive member 52, the 6 installation positions are sequentially arranged at intervals, and the 6 groups of lead groups 01 are respectively installed on the 6 installation positions, so that the lead groups 01 are staggered along the length direction of the main conductive member 52, and the structural interference between the lead groups 01 is avoided. In addition, by arranging one group of lead groups 01 at each length position of the main conductive member 52, when the number of each group of lead groups 01 is greater than one, the main conductive member 52 can be pulled in different directions through different leads 54, so as to keep the stress balance of the main conductive member 52. It is understood that, in other embodiments of the present application, the number of the wires 54 in each group of the wire groups 01 may also be one, three, or more than three, when each group of the wire groups 01 includes one wire 54, that is, the wires 54 are all staggered along the length extension direction of the main conductive element 52, and when each group of the wire groups 01 includes three or more than three wires 54, the number of the wire groups 01 may be reduced, and the lengths of the main conductive element 52 and the sub-conductive elements 53 may also be reduced, so as to reduce the occupied space of the entire power supply structure 5 along the length direction of the main conductive element 52, which is not limited herein.

In one embodiment, referring to fig. 12, each group of wires 01 includes at least two wires 54; in the same lead group 01, the positions where the at least two leads 54 are connected to the main conductive member 52 are located at the same length position of the main conductive member 52, the at least two leads 54 are connected to the main conductive member 52 at different positions in the circumferential direction, and the at least two leads 54 are arranged at equal intervals in the circumferential direction of the main conductive member 52. In this embodiment, at least two wires 54 located at the same length position of the main conductive member 52 are staggered at equal intervals along the circumferential direction of the main conductive member 52, so that the wires 54 in the same wire group 01 are prevented from being intertwined with each other, and interference between connectors on the main conductive member 52 for connecting the wires 54 is also avoided, and the wires 54 in the same wire group 01 are respectively connected with different positions on the main conductive member 52 in the circumferential direction, so that the acting forces of the wires 54 on the main conductive member 52 are uniformly distributed along the circumferential direction and are mutually offset, thereby balancing the stress of the main conductive member 52 and maintaining the position stability.

Alternatively, referring to fig. 12, each of the sub-conductive members 53 moves around the main conductive member 52 along a racetrack track, and during the movement of each sub-conductive member 53, two sub-conductive members 53 are always disposed symmetrically with respect to the center line of the main conductive member 52. Therefore, in this embodiment, each group of wires 01 includes two wires 54, and the two wires 54 are connected to the main conductive member 52 at different positions in the circumferential direction.

In one embodiment, referring to fig. 12, the connection positions of the wires 54 and the main conductive member 52 are equally spaced along the circumference of the main conductive member 52, for example, 12 wires 54 are circumferentially offset from each other in fig. 12, so that the wires 54 are all connected to the main conductive member 52 in a straight line without a detour connection.

In one embodiment, the main conductive member 52 is rotatably disposed about a centerline of the main conductive member 52. For example, referring to fig. 13, the main conductive member 52 is rotatably disposed on the frame 6. Specifically, through holes are formed in two opposite positions of the frame 6, and the main conductive member 52 is rotatably disposed in the two through holes along opposite ends in the length direction. When each of the sub-conductive members 53 is driven by the external feeding mechanism to move along the track, each of the sub-conductive members 53 pulls each of the conductive wires 54 in the circumferential direction, thereby rotating the main conductive member 52 about its center line. In the present embodiment, the main conductive element 52 is arranged to rotate around its center line, so that when the sub-conductive elements 53 move along the track-type track, the wires 54 are also carried along, and in order to avoid the wires 54 from winding on the main conductive element 52 and the wires 54 from winding on each other, the main conductive element 52 is arranged to rotate around its center line.

In this embodiment, the provision of the copper bar 521 improves the electrical conductivity and structural strength of the copper bar 521; the connection between the copper bar 521 and the lead 54 can be realized by the arrangement of the first connection terminal 523; by providing the insulating sleeve 522 to insulate the copper bar 521 from the outside, the main conductor 52 can be used in a conductive environment, for example, the main conductor 52 can be provided in a plating solution environment, that is, each plating unit 1 can be supplied with power in the plating solution through the copper bar 521.

In one embodiment, referring to fig. 13, the main conductive member 52 further includes a plurality of sealing sleeves 524, and the sealing sleeves 524 are respectively sleeved at different positions of the insulating sleeve 522 along the axial direction.

In one embodiment, referring to fig. 14, the conductive member 53 includes an electrode shaft 531, a second connection terminal 532, and a plurality of positive electrodes 533. The electrode shaft 531 extends in the same direction as the copper bar 521, and the electrode shaft 531 is made of a conductive material, such as copper. The second connection terminals 532 are disposed on the electrode shaft 531 and electrically connected to the wires 54, and a plurality of positive electrodes 533 are distributed on the electrode shaft 531 along a length extending direction of the electrode shaft 531.
