[0029] Further, the octagonal shell 1 is a hollow structure, each side plane of the octagonal shell 1 is provided with an array of holes, so that the plating solution can quickly pass through the drum during work, and the problem of poor exchange of waste liquid and new liquid caused by poor flow can be avoided.

[0030] Further, the conductive copper plate 11 is located at the center of the end face of one side of the octagonal shell 1, the conductive copper plate 11 converges to a circular truncated cone towards the center and the center protrusion is cut with a central copper thread ring 13 for screwing connection of the replaceable contact electrode 14, the conductive copper plate 11 of the side plane of the octagonal shell 1 extends outwardly at the center of each side plane of the octagonal shell 1 and is threadedly connected with an array of electrode bumps 7 exposed inside the octagonal shell 1.

[0031] Further, the replaceable contact electrode 14 is a nut-shaped solid copper metal, one end of the replaceable contact electrode 14 is an octagonal prism, the other end is a threaded column, and the cross section radius of the end with the threaded column is slightly smaller than the radius of the inscribed circle of the cross section of the end with the octagonal shape, the top end of one side of the octagonal nut-shaped side has a conical recess for external electrode connection, which is similar to the shape of a nut and can minimize the centering error when two electrodes are in contact, avoid the problem of excessive current parameter error caused by too small contact area, stress concentration or resistivity rise of the material, and local overheating caused by severe friction, the replaceable contact electrode 14 usually needs to be completely immersed in the plating solution and needs to work in different working environments and acidities, there is a certain degree of corrosion and wear, in order to maximize the production and maintenance cost under the premise of ensuring functionality, improve production efficiency, therefore the threaded electrode makes the replaceable contact electrode 14 with lower processing and installation cost as a consumable part by simple screwing structure, and the conductive copper plate 11 of the octagonal shell 1 does not need to be replaced.

[0032] Further, the electrode bump 7 body is a cylindrical structure, the top is fixedly connected with a copper hemisphere, the bottom column surface is threaded, the waist is an octagonal skirt and is sleeved with a fluororubber ring 8, the part is also a consumable part, the fluororubber ring 8 can effectively prevent the electroplating solution from entering the conductive copper plate 11 embedded in the octagonal prism shell 1, and avoid the internal conductive copper plate 11 from being corroded.

[0033] Further, the material inlet cover plate 2 is located at the left end face of the column, the opening is square, the material inlet cover plate 2 is an independent screw-in locking cover plate, double handles are additionally arranged on the outer surface, and four locking buckles are jointly arranged, which correspond to the four clamping grooves on the octagonal prism shell 1, so that the octagonal prism shell 1 is fixed.

[0034] Further, the non-metallic grabbing ring 3 is an annular double-inclined-surface wedge groove embedded in one end of the octagonal prism shell 1, the rear side of the inner side inclined surface of the wedge groove has a column surface with a smaller radius than the top end of the front inclined surface, the axis is collinear with the axis of the octagonal prism shell 1, and the wedge groove is contracted from outside to inside. When a wedge-shaped grabbing structure with a complementary shape contacts the wedge groove, the normal pressure of the pointing axis of the barrel body is converted into an axial force parallel to the axis through the two inclined surfaces, and the grabbing force of the clamping jaw is achieved through the double-side force to self-position the barrel in the axial direction, thereby reducing the axial movement.

[0035] Further, the annular toothed disc 10 is located at the side surface of the electrode side end face, the division circle is slightly larger than the circumscribed circle of the regular octagonal end face, the transmission teeth of the annular toothed disc 10 are not completely punched through, the tooth width length is smaller than the thickness of the end face, and the tail part is in a circular arc shape, and the annular toothed disc 10 rotates in the same direction as the octagonal prism shell 1.

[0036] Working principle:

[0037] First, hold the material inlet cover plate 2 with both hands, rotate and open it, then load the parts to be electroplated, and the loaded parts should not be too much and should not be gathered on one side of the barrel body. Then, the four buckles of the material inlet cover plate 2 are correspondingly connected with the interfaces of the barrel body, and the cover plate is closed.

[0038] Then, the mechanical hand clamping jaw moves to the vicinity of the non-metallic grabbing ring 3, the clamping jaw is coplanar with the axial plane where the non-metallic grabbing ring 3 is located, the top end of the clamping jaw is slowly contacted with the wedge block with a complementary shape to the wedge-shaped ring surface of the wedge groove, the two sides have consistent angles, and the planes are completely contacted. With the increase of the clamping force of the mechanical jaw, the normal pressure of the pointing axis of the barrel body is converted into an axial parallel force through the double-inclined-surface structure, the displacement is increased, then the clamping jaw is completely embedded in the wedge groove, the axial forces on the two sides are equal, the displacement is stopped, the axial displacement of the barrel body is locked, the mechanical jaw lifts the roller, and the three retaining frames 6 equally connected in series on the barrel body transmit the bending moment to the eight anti-bending steel bars 4 through the holes on the retaining frames 6. The pressure bearing of the octagonal prism shell 1 is reduced.

[0039] The drum is put into the container with electroplating liquid, and the step with nonmetallic grabbing ring 3 on one side and the arc plane on the side of the annular gear disc 10 on the other side, so when contacting and driving with the corresponding driving structure, the axial displacement will also be locked. The cylindrical surface of the nonmetallic grabbing ring 3 only bears the supporting force, and the annular gear disc 10 bears the supporting force and the radial driving force at the same time. The conical groove of the replaceable contact electrode 14 at the tail part will contact with the external same-angle conical conductive copper joint, and the current is transmitted to the conductive copper plate 11 inside the drum through the replaceable contact electrode 14, and the conductive copper plate 11 leads the current to each side plane of the barrel, and the electrode bump 7 array connected thereto starts to be electrified and contacts the parts to be plated.

[0040] Then the driving structure starts to work, the rotating force is transmitted to the drum through the annular gear disc 10, the drum starts to roll in the electroplating liquid, the electroplating liquid enters the inside through the hole of the octagonal prism shell 1, and the anti-bending steel bar corrosion-resistant PP plastic 5, the conductive copper plate corrosion-resistant PP plastic 12, the corrosion-resistant protective cover 9, the replaceable contact electrode protective sleeve 15, the fluororubber ring 8 and the center copper thread ring protective sleeve 16 protect the metal parts inside.

[0041] After the electroplating work is completed, the clamping jaw regrabs the nonmetallic grabbing ring 3, takes out the drum from the electroplating container containing the electroplating liquid, and puts it into the conveying device to wait for the next process. Thus, the electroplating process is completed.

[0042] The above is only an embodiment of the present application, and the specific structure and characteristics of the scheme and the like are not described in detail. For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and the present application can be realized in other specific forms without departing from the spirit or basic characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
