Description

Technical Field

[0001] This utility model relates to the field of electroplating technology, specifically to electroplating production lines and electroplating equipment. Background Technology

[0002] In integrated roller-mount electroplating production lines, the rotation of the hangers is usually driven independently, either horizontally or vertically. Traditionally, vertical rotation is driven by a motor via 24V conductive contacts on the edge of the tray. This transmission method presents quality and efficiency issues for daily production and maintenance. To address this challenge, this utility model patent proposes an innovative shared transmission method for the roller-mount system. This reduces the risk of gas corrosion affecting motor wiring and conductive contacts, while ensuring simple and convenient maintenance and cost savings.

[0003] Technical Background: In traditional vertical rotation methods, each hanger is equipped with a separate low-voltage motor, which is driven by conductive contacts on the side of the plating tank to rotate the hanger. The motor and electrical components are located directly above the plating tank, in close proximity, leading to severe corrosion, hindering continuous production, and causing numerous inconveniences for maintenance. Therefore, a method is needed to replace the individual motor operation and power supply via conductive contacts, reducing electroplating quality defects caused by corrosion, improving production efficiency, and saving maintenance costs.

[0034] The following description, with reference to the accompanying drawings, introduces an electroplating production line and electroplating equipment provided by this utility model.

[0035] like Figures 1 to 6 As shown, the electroplating production line according to the first aspect of the present invention includes a drive motor 1, a main transmission shaft 11, several sets of vertical rotating hangers 2, a vertical transmission mechanism, several sets of horizontal rotating hangers 3, and a horizontal transmission mechanism.

[0036] The drive motor 1 is connected to the main drive shaft 11; the vertical rotating hanger 2 is connected to the main drive shaft 11 through a vertical transmission mechanism, and the vertical rotating hanger 2 rotates with the up and down direction as the axis; the horizontal rotating hanger 3 is connected to the main drive shaft 11 through a horizontal transmission mechanism, and the horizontal rotating hanger 3 rotates with the left and right direction as the axis.

[0037] The electroplating production line according to an embodiment of this utility model has the following specific structure:

[0038] The drive motor 1 serves as the power source for the entire electroplating production line. It is directly connected to the main drive shaft 11 via a transmission device (such as a coupling or reducer 4) to provide rotational power for the subsequent transmission system. The main drive shaft 11 extends in the front-to-back direction, running through the entire production line. As the core component for power distribution, it transmits the power of the drive motor 1 to the transmission mechanisms of the vertical rotating hanger 2 and the horizontal rotating hanger 3.

[0039] The vertical rotating fixture 2 is connected to the main drive shaft 11 via a vertical transmission mechanism. The vertical rotating fixture 2 rotates along the vertical axis to fix the workpiece and perform electroplating operations in the vertical direction. For example, the vertical transmission mechanism can consist of a gear set (such as helical gears) and a drive shaft, transmitting power from the main drive shaft 11 to the vertical rotating fixture 2, thereby ensuring the stability of its rotational movement.

[0040] The horizontal rotating fixture 3 is connected to the main drive shaft 11 via a horizontal transmission mechanism. The horizontal rotating fixture 3 rotates around a left-right axis to fix the workpiece and achieve horizontal electroplating operations. For example, the horizontal transmission mechanism can consist of a multi-stage gear set (such as external gears and internal gears) and a drive shaft to transmit power from the main drive shaft 11 to the horizontal rotating fixture 3, thereby ensuring the uniformity of its rotation.

[0041] It is understandable that the drive motor 1 and the main drive shaft 11 are used to provide a unified power source, reducing redundant configurations of individual motors and lowering hardware costs. In this way, by centrally distributing power through the main drive shaft 11, motor failures caused by poor contact of conductive contacts can be avoided.

[0042] Based on the above basic structure, the basic working principle of the electroplating production line of this utility model is as follows:

[0043] In traditional technology, vertical rotating hangers rely on conductive contacts on the groove edge for power supply, leading to motor corrosion and poor contact problems. This invention completely replaces the conductive contact power supply method with a mechanical transmission system, that is, it directly transmits power through mechanical transmission (gear sets and drive shafts), thus completely eliminating the use of conductive contacts and fundamentally solving the corrosion and poor contact problems. Specifically, the drive motor 1 and the main drive shaft 11 serve as a unified power source, directly transmitting power to the vertical rotating hanger 2 and the horizontal rotating hanger 3 through transmission mechanisms such as gear sets and drive shafts, eliminating the need for conductive contact power supply. Simultaneously, a multi-stage gear set (such as helical gears, external gears, and internal gears) is used to achieve power distribution, ensuring the stability and synchronization of the rotational movements. Furthermore, the rotation of the vertical rotating hanger 2 and the horizontal rotating hanger 3 relies entirely on mechanical transmission, therefore eliminating the need for separate motors or electrical components, further avoiding corrosion and poor contact problems. This reduces the configuration of separate motors and conductive contacts, lowering hardware costs and maintenance expenses. The corrosion resistance of the mechanical transmission significantly extends equipment life, while improving electroplating efficiency and product quality.

[0044] Furthermore, the basic working process of the electroplating production line of this utility model is as follows: In the start-up stage, after the drive motor 1 is powered on, the power is transmitted to the main drive shaft 11 through the coupling or reducer 4. The power of the main drive shaft 11 is transmitted to the vertical rotating hanger 2 through the helical gear and other components of the vertical transmission mechanism, causing it to rotate in the up-down direction. The power of the main drive shaft 11 is transmitted to the horizontal rotating hanger 3 through the multi-stage gear set and other components of the horizontal transmission mechanism, causing it to rotate in the left-right direction.

[0045] It is understood that the power for both the vertical rotating hanger 2 and the horizontal rotating hanger 3 comes from the main drive shaft 11. Through differentiated design of the transmission mechanism (e.g., the vertical transmission mechanism uses a single-stage helical gear, while the horizontal transmission mechanism uses a three-stage gear set), independent control of the two rotational movements can be achieved while maintaining the synchronicity of power transmission. Since there is no need to replace conductive contacts or deal with corroded motors, maintenance personnel only need to periodically check the lubrication status of the gear set and the tightness of the drive shaft, significantly reducing maintenance time and costs.

[0046] In summary, this invention solves the problem of low efficiency caused by corrosion and poor contact in traditional electroplating production lines by replacing conductive contacts with mechanical transmission and using a shared transmission system. The coordinated operation of the drive motor 1 and the main transmission shaft 11, combined with the differentiated design of the vertical and horizontal transmission mechanisms, enables independent control and stable operation of the vertical rotating hanger 2 and the horizontal rotating hanger 3, while significantly reducing hardware costs and maintenance difficulty, thereby achieving cost reduction and efficiency improvement.

[0047] like Figure 1 and Figure 2As shown, according to some embodiments of this utility model, several sets of vertical rotating hangers 2 and several sets of horizontal rotating hangers 3 are arranged in the front-to-back direction, and the main drive shaft 11 extends in the front-to-back direction. At least two reducers 4 are installed at intervals along the length of the drive shaft, and each reducer 4 corresponds to a set of vertical rotating hangers 2 or a set of horizontal rotating hangers 3. The reducers 4 are connected to the vertical transmission mechanism or the horizontal transmission mechanism. Furthermore, a coupling is also provided between adjacent reducers 4 on the main drive shaft 11.

[0048] In this embodiment, the main drive shaft 11 extends along the front-to-back direction, running through the entire electroplating production line. Its function is as the core channel for power distribution, transmitting the power of the drive motor 1 to each reducer 4. At least two reducers 4 are installed at intervals along the length of the main drive shaft 11, each reducer 4 corresponding to either a set of vertical rotating hangers 2 or a set of horizontal rotating hangers 3. The reducers 4 are connected to the vertical / horizontal rotating hangers 3 via a transmission mechanism (such as a gear set) to achieve independent drive.

[0049] The coupling is installed between adjacent reducers 4 to compensate for installation errors, that is, to absorb minor misalignments between reducer 4 and main drive shaft 11, while reducing the transmission of vibrations generated during the operation of reducer 4 and improving system stability. In addition, the coupling can also provide overload protection. For example, when a set of hangers jams due to excessive load, the coupling can disconnect the power transmission, thereby preventing the entire main drive shaft 11 from stopping.

[0050] In this way, the present invention allows each set of hangers to be driven by a corresponding reducer 4, thereby ensuring that the rotational speed and direction of different hanger sets can be flexibly adjusted according to production needs and avoiding mutual interference. Simultaneously, by distributing the power of the main drive shaft 11 to multiple independent reducers 4, overheating or wear of a single reducer 4 due to concentrated load can be avoided. Furthermore, the coupling, by absorbing vibration and compensating for installation errors, can reduce mechanical shock to the transmission system, lower noise and failure rates, and provide overload protection under abnormal conditions.

[0051] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the reducer 4 is provided with an output gear 12, which rotates around a left-right axis and is connected to a vertical transmission mechanism or a horizontal transmission mechanism.

[0052] In this embodiment, each reducer 4 is equipped with an output gear 12, which rotates about a left-right axis. When the reducer 4 drives the vertical rotating hanger 2, its output gear 12 meshes with a gear set (such as a helical gear) in the vertical transmission mechanism, transmitting power to the vertical rotating hanger 2 through a series of mechanical transmissions, causing it to rotate about a vertical axis. When the reducer 4 drives the horizontal rotating hanger 3, its output gear 12 meshes with a gear set (such as a multi-stage gear) in the horizontal transmission mechanism, transmitting power to the horizontal rotating hanger 3 through a series of mechanical transmissions, causing it to rotate about a left-right axis.

[0053] In this way, each reducer 4 drives a set of hangers independently through its output gear 12, ensuring precise power distribution between different hanger groups and avoiding power imbalance caused by sharing the same reducer 4. The output gear 12 directly meshes with the corresponding transmission mechanism, reducing energy loss in intermediate links and improving the efficiency of the entire transmission system. Furthermore, the use of mechanical transmission instead of electrical components (such as conductive contacts) reduces the risk of failure due to corrosion or poor contact, improving the stability and reliability of the system.

[0054] like Figure 4 and Figure 6 As shown, in some specific embodiments of this utility model, the horizontal transmission mechanism includes a first gear 51, a second gear 52 and a third gear 53 distributed sequentially in the vertical direction. The output gear 12 meshes with the first gear 51. The first gear 51, the second gear 52 and the third gear 53 mesh and transmit power sequentially and rotate about the left and right direction as the axis. The third gear 53 is connected to the horizontal rotating hanger 3.

[0055] In the horizontal transmission mechanism of this embodiment, the first gear 51 is located at the top and directly meshes with the output gear 12 of the reducer 4. The second gear 52 is located below the first gear 51 and meshes with the first gear 51. The third gear 53 is located at the bottom, meshes with the second gear 52, and is directly connected to the horizontal rotating hanger 3.

[0056] The gear transmission path is as follows: The output gear 12 of the reducer 4 rotates around its left-right axis and meshes with the first gear 51. The first gear 51 meshes with the second gear 52, transmitting power to the second gear 52. The second gear 52 then transmits power to the third gear 53, which ultimately drives the horizontal rotating fixture 3 to rotate.

[0057] In this way, a stable and efficient power transmission path is achieved through the sequential meshing of the first gear 51, the second gear 52, and the third gear 53. This design not only ensures the continuity of power transmission but also effectively reduces energy loss, ensuring that the horizontal rotating hanger 3 can obtain sufficient power to rotate.

[0058] Meanwhile, the use of multi-stage gear transmission allows for more precise control of the rotation speed and angle of the horizontal rotating fixture 3, ensuring the uniformity of the workpiece during electroplating. This is crucial for improving electroplating quality. Furthermore, the multi-stage gear design enables the system to better adapt to different load conditions, maintaining stable operation even under significant load variations, thus enhancing the overall stability of the production line.

[0059] like Figure 6 As shown, the first gear 51 further includes an external gear portion 511 and an internal gear portion 512 coaxially arranged. The radius of the external gear portion 511 is larger than the radius of the internal gear portion 512. The external gear portion 511 meshes with the output gear 12, and the internal gear portion 512 meshes with the second gear 52.

[0060] In this embodiment, the first gear 51 consists of an external gear portion 511 and an internal gear portion 512, which are coaxial and rotate synchronously. The radius of the external gear portion 511 is larger than the radius of the internal gear portion 512, thereby allowing the external gear portion 511 to mesh with the output gear 12 of the reducer 4, while the internal gear portion 512 meshes with other gears (such as the second gear 52).

[0061] It is understandable that by using an external gear section 511 and an internal gear section 512 with different numbers of teeth, two different transmission ratios can be achieved on a single gear. This allows the system to flexibly adjust the speed and torque of each part according to actual needs, thereby optimizing the performance of the entire transmission chain.

[0062] The large diameter of the external gear section 511 can provide a larger torque output, making it suitable for applications that drive large loads or require high starting torque; while the small diameter of the internal gear section 512 helps to increase the rotational speed, making it suitable for subsequent high-speed transmission links.

[0063] In this way, by integrating two functions (high torque output and high speed transmission) onto a single gear, the number of gears required is reduced, the mechanical structure is simplified, manufacturing costs are lowered, and system reliability is improved. At the same time, the coaxial design of the first gear 51 reduces energy loss caused by different shaft centers, improving overall transmission efficiency.

[0064] For example Figure 4 and Figure 6As shown, in the process of the horizontal transmission mechanism driving a set of horizontal rotating hangers 3: the output gear 12 of the reducer 4 rotates around its left-right axis and meshes with the outer gear portion 511 of the first gear 51. The large diameter of the outer gear portion 511 provides sufficient torque to ensure effective driving of subsequent transmission components. The inner gear portion 512 of the first gear 51 meshes with the second gear 52, transmitting the power after initial reduction to the second gear 52. Due to the smaller radius of the inner gear portion 512, it can provide a higher rotational speed, suitable for subsequent high-speed transmission stages. The second gear 52 continues to transmit power to the third gear 53. The third gear 53 is directly connected to the horizontal rotating hanger 3, driving the hanger to rotate around its left-right axis.

[0065] In this process, the design of the first gear 51 not only achieves efficient torque transmission but also optimizes the transmission ratio through its internal structure, ensuring the smooth operation of the entire transmission chain. Furthermore, this design allows the system to flexibly adjust the speed and torque of each transmission link according to actual production needs, further improving the overall performance of the production line.

[0066] like Figure 4 As shown, in some specific embodiments of this utility model, each group of horizontal rotating hangers 3 includes two horizontal rotating hangers 3 spaced apart in the left-right direction. The electroplating production line also includes several horizontal driven mechanisms. The horizontal driven mechanisms are connected to the first gear 51 via a first horizontal transmission shaft 57 extending in the left-right direction. One of the two horizontal rotating hangers 3 in the same group is connected to the horizontal transmission mechanism, and the other is connected to the horizontal driven mechanism.

[0067] In this embodiment, each set of horizontal rotating hangers 3 includes two horizontal rotating hangers 3, which are spaced apart in the left-right direction. Each set of horizontal rotating hangers 3 is equipped with a horizontal driven mechanism and a horizontal transmission structure, which are located at the two ends in the left-right direction and correspond to the two horizontal rotating hangers 3 respectively.

[0068] The first horizontal drive shaft 57 serves as the medium for power transmission, distributing the power of the first gear 51 to the horizontal driven mechanism and a horizontal rotating fixture 3 directly connected to the horizontal drive mechanism. Thus, of the two horizontal rotating fixtures 3 in the same group, one fixture is directly connected to the horizontal drive mechanism, receiving power from the first gear 51 and rotating; the other fixture is connected to the first horizontal drive shaft 57 via the horizontal driven mechanism, indirectly receiving power and rotating.

[0069] By setting two horizontal rotating hangers 3 within the same group, the load on each hanger is more evenly distributed, preventing overload of a single hanger from affecting electroplating quality or causing equipment failure. Furthermore, one hanger is directly driven by a horizontal transmission mechanism, while the other is driven by a horizontal driven mechanism. This design allows for flexible adjustment of the working state of each hanger according to actual needs, thereby improving the system's adaptability.

[0070] like Figure 4 As shown, the horizontal driven mechanism further includes a fourth gear 54, a fifth gear 55 and a sixth gear 56 distributed sequentially in the vertical direction. The fourth gear 54 is mounted on the first horizontal transmission shaft 57 and rotates coaxially with the first gear 51. The fourth gear 54, the fifth gear 55 and the sixth gear 56 mesh and drive in sequence and rotate about the left and right direction. The sixth gear 56 is connected to the horizontal rotating hanger 3.

[0071] In this embodiment, the fourth gear 54 is mounted on the first horizontal transmission shaft 57 and rotates coaxially with the first gear 51. At this time, the fourth gear 54 directly receives power from the first gear 51. The fifth gear 55 and the sixth gear 56 are distributed sequentially along the vertical direction and mesh with the fourth gear 54 and the preceding gear (i.e., the fifth gear 55) respectively. All three gears rotate about a left-right axis, thereby ensuring the consistency of power transmission direction.

[0072] The transmission path within the horizontal driven mechanism is as follows: The fourth gear 54 is the starting point of the horizontal driven mechanism, connected to the first gear 51 via the first horizontal transmission shaft 57, receiving and transmitting power. The fifth gear 55 meshes with the fourth gear 54, continuing to transmit power to the next gear. The sixth gear 56 meshes with the fifth gear 55 and finally connects to the horizontal rotating hanger 3, driving the hanger to rotate.

[0073] In this way, a stable and efficient power transmission path is achieved through the sequential meshing of the fourth gear 54, the fifth gear 55, and the sixth gear 56. This design not only ensures the continuity of power transmission but also effectively reduces energy loss, ensuring that the horizontal rotating fixture 3 receives sufficient power to rotate. Simultaneously, all gears rotate around a left-right axis, ensuring directional consistency during power transmission and avoiding energy loss or mechanical failure caused by changes in direction.

[0074] In addition, the horizontal driven mechanism, as an independent module, is easy to replace or repair quickly when needed, without the need for large-scale disassembly of the entire system, thus reducing maintenance difficulty and cost.

[0075] For example Figure 4As shown, a set of horizontal rotating hangers 3 includes two hangers and is equipped with corresponding horizontal driven mechanisms. The specific working process is as follows: The output gear 12 of the reducer 4 meshes with the outer gear portion 511 of the first gear 51, providing power to the first gear 51. The inner gear portion 512 of the first gear 51 meshes with the second gear 52, continuing to transmit power to subsequent gear assemblies. The second gear 52 transmits power to the third gear 53, ultimately driving one of the horizontal rotating hangers 3 to rotate around its left-right axis.

[0076] The fourth gear 54 is mounted on the first horizontal transmission shaft 57 and rotates coaxially with the first gear 51, receiving power from the first gear 51. The fourth gear 54 meshes with the fifth gear 55, transmitting power to the fifth gear 55. The fifth gear 55 then meshes with the sixth gear 56, continuing to transmit power to the sixth gear 56. Finally, the sixth gear 56 connects to another horizontal rotating fixture 3, driving the fixture to rotate about a left-right axis.

[0077] During this process, both sets of horizontal rotating fixtures 3 operate smoothly, and the multi-stage transmission and driven mechanism design ensures the continuity and stability of power transmission. Furthermore, this design allows for flexible adjustment of the rotation speed and direction of each fixture according to actual production needs, further improving electroplating quality and production efficiency.

[0078] like Figure 3 and Figure 5 As shown, according to some embodiments of the present invention, the vertical transmission mechanism includes a seventh gear 61, a second horizontal transmission shaft 62, a first vertical helical gear 63, and a first horizontal helical gear 64. The output gear 12 meshes with the seventh gear 61. The seventh gear 61 and the first vertical helical gear 63 are both mounted on the second horizontal transmission shaft 62 and rotate about the left and right directions. The first vertical helical gear 63 and the first horizontal helical gear 64 mesh. The first horizontal helical gear 64 is connected to the vertical rotating hanger 2 and rotates about the up and down directions.

[0079] In this embodiment, the seventh gear 61 directly meshes with the output gear 12 of the reducer 4, serving as the first step in power input. The second horizontal drive shaft 62 is used to mount the seventh gear 61 and the first vertical helical gear 63, enabling them to rotate synchronously. The second horizontal drive shaft 62 extends in the left-right direction and rotates around this axis. The first vertical helical gear 63 is mounted on the second horizontal drive shaft 62 and rotates coaxially with the seventh gear 61, its function being to convert horizontal power into vertical power. The first horizontal helical gear 64 meshes with the first vertical helical gear 63, further transmitting power. The first horizontal helical gear 64 rotates around this axis and is directly connected to the vertical rotating hanger 2.

[0080] The transmission path is as follows: The seventh gear 61 receives power from the output gear 12 of the reducer 4 and transmits it to the first vertical helical gear 63 via the second horizontal transmission shaft 62. The first vertical helical gear 63 converts the horizontal power transmitted from the seventh gear 61 into vertical power and continues to transmit it through meshing with the first horizontal helical gear 64. The first horizontal helical gear 64 receives power from the first vertical helical gear 63 and ultimately drives the vertical rotating hanger 2 to rotate around its vertical axis.

[0081] In this way, by using the first vertical helical gear 63 and the first horizontal helical gear 64, the power conversion from the horizontal to the vertical direction is achieved. This design not only improves transmission efficiency but also reduces energy loss. Furthermore, the helical gear design allows for more precise control of the rotational speed and torque of the vertical rotating fixture 2, ensuring a uniform electroplating effect on the workpiece during the electroplating process. In addition, the vertical transmission mechanism, as an independent module, facilitates quick replacement or maintenance when needed, eliminating the need for large-scale disassembly of the entire system and reducing maintenance difficulty and cost.

[0082] For example Figure 3 and Figure 5 As shown, the vertical transmission mechanism drives a set of vertical rotating hangers 2. Its operation is as follows: The output gear 12 of the reducer 4 meshes with the seventh gear 61, providing power to the seventh gear 61. The seventh gear 61 is mounted on the second horizontal transmission shaft 62 and rotates coaxially with the first vertical helical gear 63, transmitting power to the first vertical helical gear 63. The first vertical helical gear 63 converts the horizontal power into vertical power and continues to transmit it through meshing with the first horizontal helical gear 64. The first horizontal helical gear 64 rotates on its vertical axis and is directly connected to the vertical rotating hanger 2, driving the hanger to rotate vertically.

[0083] In this process, the seventh gear 61 and the first vertical helical gear 63 both rotate around their left-right axes, while the first horizontal helical gear 64 rotates around its up-down axis, thus achieving a power conversion from horizontal to vertical. This design not only ensures the continuity and consistency of power transmission but also reduces energy loss and the risk of mechanical failure through reasonable design.

[0084] like Figure 3 and Figure 5As shown, in some specific embodiments, each set of vertical rotating hangers 2 includes two vertical rotating hangers 2 spaced apart in the left-right direction. The electroplating production line also includes several vertical driven mechanisms. The vertical driven mechanisms include a second vertical helical gear 71, a third horizontal transmission shaft 72, a third vertical helical gear 73, a second horizontal helical gear 74, and a fourth vertical helical gear 75. The second vertical helical gear 71 meshes with the first horizontal helical gear 64. The second vertical helical gear 71 and the third vertical helical gear 73 are both mounted on the third horizontal transmission shaft 72 and both rotate about the left-right direction. The third vertical helical gear 73, the second horizontal helical gear 74 mesh, and the fourth vertical helical gear 75 meshes in sequence. The fourth vertical helical gear 75 rotates about the left-right direction.

[0085] In this embodiment, each set of vertical rotating hangers 2 includes two vertical rotating hangers 2 spaced apart along the left-right direction. In the vertical driven mechanism, the second vertical helical gear 71 meshes with the first horizontal helical gear 64, receiving power from the main transmission path. The third horizontal transmission shaft 72 is used to mount the second vertical helical gear 71 and the third vertical helical gear 73, enabling them to rotate synchronously around the left-right axis. The third vertical helical gear 73 is mounted on the third horizontal transmission shaft 72, meshes with the second vertical helical gear 71, and continues to transmit power to the next stage. The second horizontal helical gear 74 meshes with the third vertical helical gear 73, serving as an intermediate transition component to change the direction of power transmission. The fourth vertical helical gear 75 meshes with the second horizontal helical gear 74, rotating around the vertical axis (or achieving vertical rotation through connection), and finally connects to the second vertical rotating hanger 2.

[0086] In the same group of two vertical rotating hangers 2, one hanger is directly connected to the first horizontal helical gear 64 in the vertical transmission mechanism and is driven by the main transmission path; the other hanger is indirectly driven through the vertical driven mechanism and receives multi-stage transmission power from the second vertical helical gear 71, the third vertical helical gear 73, the second horizontal helical gear 74, and the fourth vertical helical gear 75.

[0087] In this way, the cooperation between the main drive path and the vertical driven mechanism ensures that the two vertical rotating fixtures 2 in the same group operate in the same direction and at the same speed, avoiding uneven electroplating caused by differences in speed. Furthermore, the design of the vertical driven mechanism allows for the arrangement of two fixtures in the same group, improving the space utilization of the production line; simultaneously, the load is rationally distributed across multiple gear assemblies, reducing the stress on individual gears and extending the equipment's service life. In addition, the vertical driven mechanism, as an independent module, is easy to disassemble, replace, and maintain, reducing downtime.

[0088] For example Figure 3 and Figure 5As shown, after the drive motor 1 is powered on, it transmits power to the main drive shaft 11 through a coupling or reducer 4, and then from the main drive shaft 11 to each reducer 4. The output gear 12 of the reducer 4 meshes with the seventh gear 61, which is mounted on the second horizontal drive shaft 62 and rotates coaxially with the first vertical helical gear 63, thus receiving and transmitting power. The first vertical helical gear 63 converts the horizontal power transmitted from the seventh gear 61 into vertical power, and continues to transmit it through meshing with the first horizontal helical gear 64. The first horizontal helical gear 64 receives the vertical power and drives the first vertical rotating fixture 2 to rotate in the up-down direction. At this time, the first vertical rotating fixture 2 begins to work, ensuring uniform electroplating on the workpiece surface.

[0089] The first horizontal helical gear 64 simultaneously meshes with the second vertical helical gear 71, transmitting part of the power to the vertical driven mechanism. The second vertical helical gear 71 is mounted on the third horizontal transmission shaft 72 and rotates coaxially with the third vertical helical gear 73. The second vertical helical gear 71 transmits power to the third vertical helical gear 73, which then meshes with the second horizontal helical gear 74 to continue transmitting power. The second horizontal helical gear 74 meshes with the fourth vertical helical gear 75, which rotates around its vertical axis, ultimately driving the second vertical rotating fixture 2 to rotate vertically. At this time, the second vertical rotating fixture 2 also begins to work, ensuring uniform electroplating on the surface of another set of workpieces.

[0090] In summary, this utility model achieves efficient power distribution and stable synchronous operation of the two hangers by setting up a structure in which each group includes two vertical rotating hangers 2 and using a vertical driven mechanism.

[0091] Based on the above description of the electroplating production line, the technical solution of this application has the following effects:

[0092] (1) Hybrid transmission: A single transmission structure solves the previous method of separate transmission, optimizes mechanical design, and is easy to install and operate.

[0093] (2) Solve the problem of motor failure due to poor contact of conductive contacts: Mechanical power transmission can greatly improve the efficiency of rotation, thereby ensuring the uniformity and reliability of electroplated products, and guaranteeing quality and quantity.

[0094] (3) Cost reduction and efficiency improvement: Reduce the hardware cost of individual motors and electrical components, optimize the design, reduce the problem of poor electroplating quality of corroded electrical strips, improve production efficiency, and save maintenance costs.

[0095] In summary, the electroplating rack's horizontal and vertical rotation hybrid linkage mechanical structure of this patent not only improves the electroplating quality but also optimizes the operation process and saves labor and time costs.
