Description

Technical Field

[0001] This utility model relates to the field of electroplating equipment technology, and in particular to a multi-axis rotary reciprocating electroplating fixture and an electroplating device. Background Technology

[0002] During the electroplating process, due to individual differences in the workpieces to be plated, differences in conductivity, differences in mounting position, differences in the relative position of the anode plate and the workpieces to be plated, as well as differences in the circulation capacity of the bath and temperature distribution, it is difficult to avoid the formation of differences in electric field distribution and cathode concentration polarization on the workpieces to be plated, which ultimately manifests as uneven coating on the electroplated products.

[0003] In the traditional rack-plating process for silver-plating rods, the relative position of the workpiece and the anode generally remains unchanged. The electric field lines directly facing the anode are consistently denser, resulting in faster ion deposition rates on the anode side compared to the other sides. After the same deposition time, the coating thickness is also greater on the anode side. The longer the deposition time, the greater the difference in thickness between the anode-facing side and other surfaces. This results in an "elliptical" coating on the radial cross-section of the rod and a coating with higher thickness at both ends and lower thickness in the middle on the axial cross-section. This unevenness in the radial and radial coatings of the rod is mainly manifested in the difference in coating thickness within the same tank and on the same piece. Utility Model Content

[0027] The first ends of the two cables are connected to the output end of the cam linkage mechanism, and the second ends of the two cables pass over the two pulleys on both sides and are connected to the two ends of the swing frame.

Detailed Implementation

[0057] One of the core features of this invention is to provide a multi-axis rotary reciprocating electroplating fixture. The structural design of this multi-axis rotary reciprocating electroplating fixture enables it to improve the problem of radial and axial coating uniformity of rod-shaped workpieces to be plated.

[0058] Another key aspect of this invention is to provide an electroplating device that includes the aforementioned multi-axis rotary reciprocating electroplating fixture.

[0059] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0060] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the multi-axis rotary reciprocating electroplating fixture provided in an embodiment of the present invention. Figure 2 The front view of the multi-axis rotary reciprocating electroplating fixture provided in the embodiment of this utility model.

[0061] This utility model discloses a multi-axis rotary reciprocating electroplating rack, which includes a rack body, a revolution device 4, a rotation device 5, a drive device 3, a reciprocating device 7, and a conductive device 6.

[0062] The hanging device includes a main frame 1 and a swing frame 2 rotatably mounted on the main frame 1 around a first axis. The two ends of the swing frame 2 can swing up and down relative to the main frame 1. Figure 3 As shown, the main frame 1 is provided with a first bearing seat 9 for rotatable connection with the swing frame 2. The two first bearing seats 9 are symmetrically arranged, and correspondingly, as shown... Figure 4 As shown, the swing frame 2 is provided with two swing rotation shafts 10 that are rotatably engaged with the first bearing seat 9. The axis of the swing rotation shaft 10 is the first axis. The swing rotation shaft 10 is inserted into the first bearing seat 9 and rotatably engaged with the first bearing seat 9, so that the swing frame 2 is rotatably mounted on the main frame 1.

[0063] The orbital device 4 includes an orbital support 28 and a first transmission mechanism. The orbital supports 28 are respectively installed at both ends of the swing frame 2, and the orbital supports 28 are rotatably mounted on the swing frame 2 around a second axis. Figure 3 As shown, the second axis is parallel to the first axis so that the orbital device 4 remains in a vertical suspended state during the swing of the swing frame 2. The first transmission mechanism is rotatably mounted on the orbital support 28. The two ends of the swing frame 2 are respectively provided with second bearing seats 11. The first transmission mechanism is rotatably mounted on the swing frame 2 through the second bearing seats 11.

[0064] The self-rotating device 5 includes a second transmission mechanism and a hook 32. Multiple second transmission mechanisms are arranged circumferentially around the first transmission mechanism on the revolution support 28, and each second transmission mechanism is connected to the first transmission mechanism for transmission. The hook 32 is located at the bottom of the second transmission mechanism.

[0065] The drive unit 3 is connected to the first transmission mechanism. Each first transmission mechanism can be connected to a drive unit 3 individually, or two first transmission mechanisms can share a drive mechanism.

[0066] The reciprocating device 7 is connected to the swing frame 2 for driving the swing frame 2 to swing back and forth relative to the main frame 1, so as to realize the swing frame 2 to float up and down alternately at both ends.

[0067] The conductive device 6 is electrically connected to each hook 32 and is used to connect to an external power source via cable 35 during the electroplating process to energize the workpiece to be plated on the hook 32.

[0068] Compared with the prior art, the multi-axis rotary reciprocating electroplating fixture provided in this embodiment of the utility model, when applied, hangs the workpiece to be plated on each hook 32. The driving device 3 drives all the workpieces to be plated to revolve through the revolution device 4. At the same time, the rotation device 5 drives the hook 32 and the workpiece to be plated to rotate while revolving. In addition, the reciprocating device 7 drives the swing frame 2 to swing up and down at both ends, so that the workpiece to be plated floats up and down in the electroplating solution. In this way, the "revolution", "rotation" and "up and down reciprocating motion" of the workpiece to be plated can be realized. This will cause the position of the workpiece to be plated facing the anode in the horizontal and vertical directions to change continuously. Moreover, each product changes according to the same law. The radial and axial positions of the rod-type workpiece to be plated have equal probability of relative position with the anode, which essentially solves the problem of uneven coating thickness of the workpiece to be plated.

[0069] like Figure 5 and Figure 6 As shown, in one embodiment of this application, the first transmission mechanism includes a revolution shaft 25, a revolution gear 29, and a revolution disk 30. The revolution shaft 25 is rotatably mounted on a revolution bracket 28 and is connected to the drive device 3. The revolution gear 29 is coaxially mounted on the revolution shaft 25 and is rotatedly fitted with the revolution shaft 25. That is, the revolution gear 29 is fixedly connected to the revolution bracket 28 through a sleeve mounted on the revolution shaft 25. The revolution disk 30 is coaxially mounted on the revolution shaft 25 and is anti-rotationally fitted with the revolution disk 30 and the revolution shaft 25.

[0070] Accordingly, such as Figure 7 As shown, the second transmission mechanism includes a rotating gear 31, which is rotatably mounted on a rotating disk 30 and meshes with a rotating gear 29. A hook 32 is connected to the rotating gear 31. During electroplating, the rotating gear 29 remains stationary relative to the rotating shaft 25 and the rotating disk 30. The rotating shaft 25, driven by the driving device 3, drives the rotating disk 30 to rotate relative to the rotating gear 29, causing each hook 32 on the second transmission mechanism and the workpiece to be plated thereon to revolve. The rotating gear 29 simultaneously drives each rotating gear 31 to rotate, causing each hook 32 and the workpiece to be plated thereon to rotate.

[0071] like Figure 8 and Figure 9 As shown, in one embodiment of this application, the driving device 3 includes a drive motor 16, a rigid shaft 19 for revolution transmission, and a flexible shaft 23 for revolution transmission. The drive motor 16 is mounted on the swing frame 2. Figure 4As shown, a motor support plate 14 is provided on the swing frame 2. The drive motor 16 is fixed to the motor support plate 14 by a plurality of first threaded fasteners 27. The revolution transmission hard shaft 19 is rotatably provided on the swing frame 2. A third bearing seat 12 is provided on the swing frame 2. The revolution transmission hard shaft 19 is rotatably provided on the swing frame 2 through the third bearing seat 12. The axis of the revolution transmission hard shaft 19 is perpendicular to the first axis and the second axis, and is connected to the motor drive shaft 17 of the drive motor 16. The two ends of the revolution transmission hard shaft 19 are respectively connected to the revolution shaft 25 through the revolution transmission flexible shaft 23 to prevent affecting the rotation of the revolution device 4 relative to the swing frame 2.

[0072] like Figures 10 to 12 As shown, in one embodiment of this application, the reciprocating device 7 includes a reciprocating transmission rigid shaft 21, a cam connecting rod 40 mechanism, a pulley 8, and cables 37 and 38. The reciprocating transmission rigid shaft 21 is rotatably mounted on the swing frame 2 and is connected to the motor drive shaft 17 of the drive motor 16. A fourth bearing seat 13 is provided on the swing frame 2, and the reciprocating transmission rigid shaft 21 is rotatably mounted on the swing frame 2 via the fourth bearing seat 13. The cam connecting rod 40 mechanism is mounted on the main frame 1. Since there is relative movement between the main frame 1 and the swing frame 2, the input end of the cam connecting rod 40 mechanism is connected via a reciprocating transmission... The flexible shaft 24 is connected to the reciprocating transmission rigid shaft 21. Two pulleys 8 are rotatably mounted on the main frame 1, corresponding to the two ends of the swing frame 2. The first ends of the two cables 37 and 38 are connected to the output end of the cam connecting rod 40 mechanism. The second ends of the two cables 37 and 38 pass over the two pulleys 8 on both sides and are connected to the two ends of the swing frame 2. That is, the second end of one cable 37 extends to one end of the main frame 1 and passes over a pulley 8 to connect to one end of the swing frame 2, and the second end of the other cable 38 extends to the other end of the main frame 1 and passes over another pulley 8 to connect to the other end of the swing frame 2.

[0073] like Figure 1 , Figure 2 , Figure 10 and Figure 11 As shown, fixed posts 15 are respectively installed at both ends of the swing frame 2 to connect the second ends of the cables 37 and 38.

[0074] like Figures 10 to 12As shown, the cam connecting rod 40 mechanism includes a crank 39, a connecting rod 40, and a reciprocating rod 36. The first end of the crank 39 is connected to the reciprocating transmission flexible shaft 24 via a reciprocating rotary shaft 26. The first end of the connecting rod 40 is rotatably connected to the second end of the crank 39. The reciprocating rod 36 is slidably mounted on the main frame 1 via a reciprocating slide rail 41. The reciprocating slide rail 41 is mounted on the main frame 1 via a second threaded fastener 42. The reciprocating rod 36 slides linearly back and forth relative to the main frame 1 along the reciprocating slide rail 41. The first end of the reciprocating rod 36 is rotatably connected to the second end of the connecting rod 40. The second section of the reciprocating rod 36 is connected to cables 37 and 38. When the crank 39 rotates, it drives the connecting rod 40 to rotate, thereby driving the reciprocating rod 36 to move back and forth.

[0075] To achieve the simultaneous rotation of the swing frame 2 and the revolution device 4 by a single drive motor 16, such as Figure 8 and Figure 9 As shown, the output end of the drive motor 16 is provided with a drive gear 18, the revolution transmission hard shaft 19 is provided with a first driven gear 20, and the reciprocating transmission hard shaft 21 is provided with a second driven gear 22. The first driven gear 20 and the second driven gear 22 respectively mesh with the drive gear 18.

[0076] like Figure 13 As shown, the conductive device 6 includes a first conductive slip ring 34 and a second conductive slip ring 33. The first conductive slip ring 34 is coaxially and rotatably mounted on the revolution shaft 25, and the second conductive slip ring 33 is coaxially and rotatably mounted on the rotating gear 31. The first conductive slip ring 34 is electrically connected to the power supply, the first conductive slip ring 34 is electrically connected to the second conductive slip ring 33, and the second conductive slip ring 33 is electrically connected to the hook 32. It can be seen that in this embodiment, the current distribution and conductivity method of the workpiece to be plated adopt a conductive slip ring structure, which avoids the metal powder generated by metal friction from contaminating the plating bath, and at the same time greatly improves the uniformity of current distribution in each branch, eliminating the source problem of uneven plating thickness caused by uneven current.

[0077] Please see Figure 14 In one embodiment of this application, an electroplating apparatus is also provided, which includes a multi-axis rotary reciprocating electroplating rack as described in the above embodiments. Since the electroplating apparatus adopts the multi-axis rotary reciprocating electroplating rack described in the above embodiments, the technical effect of the electroplating apparatus can be referred to the above embodiments.

[0078] like Figure 14 As shown, the electroplating apparatus also includes an electroplating tank 43 and a support 44. The electroplating tank 43 is used to hold the electroplating solution, and the two ends of the main frame 1 of the multi-axis rotary reciprocating electroplating fixture are respectively mounted above the electroplating tank 43 via the support 44.
