Description

Technical Field

[0001] This application relates to the field of electroplating process equipment technology, and in particular to a composite electroplating production line. Background Technology

[0002] Electroplating production lines are essential equipment for electroplating workpiece surfaces. Depending on the workpiece shape and processing requirements, common electroplating methods include rack plating and barrel plating. Rack plating is suitable for larger, more complex workpieces, typically fixed in an electroplating tank by a rack. Barrel plating is suitable for smaller batches of smaller workpieces, where the workpiece is placed in a drum and rotates to achieve uniform plating.

[0003] Currently, rack plating and barrel plating are often set up on different production lines, which not only takes up a lot of space and has high equipment investment costs, but also often requires switching between two production lines when different types of workpieces need to be processed at the same time, resulting in low production efficiency. Utility Model Content

[0004] To address the issues in related technologies where barrel plating and rack plating require separate production lines, resulting in large floor space, high costs, and the inability to process different types of workpieces simultaneously, this application provides a composite electroplating production line, employing the following technical solution: A composite electroplating production line includes multiple electroplating tanks and a drive system. The multiple electroplating tanks are arranged sequentially along the extension direction of the production line. Each electroplating tank contains an electroplating solution and includes at least one barrel plating tank and at least one rack plating tank. The barrel plating tank is equipped with a roller for holding workpieces to be barrel plating, and the roller is at least partially immersed in the electroplating solution. The rack plating tank is equipped with multiple racks for hanging workpieces to be rack plating, and the racks are at least partially immersed in the electroplating solution. The drive system is connected to the roller and the multiple racks, and the drive system drives the roller to rotate to tumble the workpieces to be barrel plating in the electroplating solution, and drives the multiple racks to rotate to rotate the workpieces to be rack plating in the electroplating solution.

[0005] By adopting the above technical solutions, both barrel plating and rack plating processes can be carried out on the same production line, reducing the production line's footprint, lowering costs, and improving production efficiency.

[0006] Optionally, the drive system includes a first drive motor and a second drive motor. The first drive motor is used to drive the plurality of hangers to rotate; the second drive motor is connected to the central shaft of the drum to drive the drum to tumble.

[0007] The above solution ensures independent drive, with rack plating and barrel plating operating without interference, resulting in more stable operation.

[0008] Optionally, the composite electroplating production line further includes a rack transmission system disposed between the first drive motor and the plurality of racks, and a roller transmission component disposed between the second drive motor and the roller, the roller transmission component including a chain and gears. The rack transmission system includes a drive wheel, a driven wheel, and an annular transmission component. The drive wheel is disposed on the output shaft of the first drive motor, each driven wheel is disposed on the rotating shaft of one of the racks, and the annular transmission component is simultaneously engaged with the drive wheel and all the driven wheels.

[0009] The above scheme, which sets up a transmission device to drive the roller and the multiple hangers, helps to achieve uniform electroplating and improves electroplating efficiency.

[0010] Optionally, the annular transmission component is a synchronous belt or a chain.

[0011] The above solution facilitates the selection of transmission methods based on actual needs, balancing stability and cost.

[0012] Optionally, the driving pulley and the driven pulley are synchronous belt pulleys or sprockets.

[0013] The above solution makes the matching between the ring transmission component and the wheel component more precise, and the transmission more reliable.

[0014] Optionally, the hanger transmission system further includes a tensioning wheel for tensioning the annular transmission member.

[0015] The above solution ensures that the ring transmission component always maintains proper tension, preventing slippage during operation.

[0016] Optionally, the first drive motor is housed in a motor housing, which is fixed above the plating tank by a support frame.

[0017] The above solution provides good protection for the first drive motor and facilitates equipment installation and maintenance.

[0018] Optionally, a hanging rod is provided on the inner wall of the electroplating tank, and the hanging rod is used to hang the anode.

[0019] The above method can provide metal ions during the electroplating process.

[0020] Optionally, adjacent electroplating tanks are separated by partitions.

[0021] The above method can prevent the electroplating solutions from mixing and causing interference, thus ensuring the quality of electroplating.

[0022] Optionally, a barrel plating frame is erected above the barrel plating tank to support the barrel.

[0023] The above solution can reliably support the roller and ensure that part of the roller is immersed in the electroplating solution.

[0024] In summary, this application has at least the following beneficial effects: 1. Integrating barrel plating and rack plating processes on the same production line enables the simultaneous processing of different types of workpieces, improving production flexibility and efficiency; 2. By setting up multiple racks and their transmission in the plating bath, the plating efficiency is improved; 3. The combination of barrel plating tanks and rack plating tanks reduces the overall floor space and lowers the production line investment cost; 4. The transmission mechanism adopts synchronous belt or chain drive and can be equipped with a tensioner, making the transmission more stable and reliable, and also making maintenance more convenient; 5. By separating the electroplating tanks with partitions, interference between different electroplating solutions can be effectively avoided, thus improving the electroplating quality.

Detailed Implementation

[0027] This application is based on the inventor's insight that existing electroplating production lines typically separate rack plating and barrel plating, resulting in large footprints, high costs, and the inability to process different types of workpieces simultaneously, leading to low efficiency. Furthermore, multiple racks in the rack plating tank often rely on independent motor drives, resulting in complex structures and high energy consumption. Therefore, there is an urgent need for a novel electroplating production line that integrates barrel plating and rack plating on the same production line and uses a unified transmission mechanism to synchronously drive multiple racks.

[0028] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0029] This application discloses a composite electroplating production line. (Refer to...) Figure 1 The composite electroplating production line includes multiple electroplating tanks 10, partitions 20, hanging rods, anodes, and a drive system. The hanging rods include barrel plating tank hanging rods 33 and rack plating tank hanging rods 44, and the anodes include barrel plating tank anodes 34 and rack plating tank anodes 45.

[0030] Reference Figure 1 The plurality of electroplating tanks 10 are arranged sequentially at intervals along a straight line, with adjacent electroplating tanks 10 connected end to end, forming a continuous production line. Each electroplating tank 10 includes at least one barrel plating tank 30 and at least one rack plating tank 40. Each electroplating tank 10 contains an electroplating solution, and adjacent electroplating tanks 10 are separated by partitions 20 to prevent mixing of different electroplating solutions. Hanging rods are provided on the inner wall of each electroplating tank 10 for hanging the anode. The anode is arranged opposite to the workpiece, forming a current loop under the action of an external current, causing the anode to gradually dissolve and replenish metal ions to the electroplating solution, thereby depositing a coating on the surface. The drive system includes a first drive motor 42a and a second drive motor 35, respectively applied to the rack plating tank 40 and the barrel plating tank 30.

[0031] Reference Figure 1 and Figure 2 The barrel plating tank 30 is equipped with a barrel plating frame 31. The barrel 32 is supported and installed by the barrel plating frame 31 and is partially immersed in the electroplating solution. The workpiece to be barrel plating is placed inside the barrel 32. The second drive motor 35 is connected to the central shaft of the barrel for transmission through a barrel transmission component, which includes a chain or gear. A barrel plating tank hanging rod 33 is provided on the inner wall of the barrel plating tank 30. The barrel plating tank hanging rod 33 is used to hang the barrel plating tank anode 34. During operation, the barrel 32 rotates and flips with the barrel plating frame 31, so that the workpiece to be barrel plating is evenly plated.

[0032] See Figure 1 and Figure 3 The plating tank 40 is equipped with hangers 41, for example, two hangers 41 arranged in parallel and spaced apart, for hanging workpieces to be plating, and each hanger 41 can be partially immersed in the plating solution. A support frame 43 is fixed above the plating tank 40, and the support frame 43 is used to install a motor housing 42. The motor housing 42 contains a first drive motor 42a, which is connected to the multiple hangers through a hanger transmission system to drive the multiple hangers 41 to rotate. A plating tank hanging rod 44 is provided on the inner wall of the plating tank 40, and the plating tank hanging rod 44 is used to hang the plating tank anode 45.

[0033] See Figure 3 and Figure 4The hanger transmission system includes a drive wheel 46, a driven wheel, an annular transmission component 48, and a tension wheel 49. The drive wheel 46 is mounted on the output shaft of the first drive motor 42a, and the driven wheels are mounted on the rotating shaft of each hanger 41. The driven wheels include, for example, a first driven wheel 47a and a second driven wheel 47b. The drive wheel 46 and the driven wheels are connected by the annular transmission component 48, which can be a synchronous belt or a chain. A tension wheel 49 can also be provided on the annular transmission component 48 to ensure that the transmission always maintains appropriate tension. During operation, the first drive motor 42a drives the drive wheel 46 to rotate, and the annular transmission component 48 transmits power to the driven wheels on each hanger 41, achieving synchronous rotation of multiple hangers 41, improving efficiency and ensuring the uniformity of electroplating on the workpiece to be plated.

[0034] With the above structure, the composite electroplating production line of this application simultaneously sets up a barrel plating tank and a rack plating tank on a single production line, which not only reduces the floor space and investment costs, but also meets the simultaneous processing needs of different types of workpieces; the rack plating tank adopts a motor and transmission mechanism to synchronously drive multiple racks, which is reliable in transmission, low in energy consumption, and ensures the electroplating quality of the workpieces.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
