Description

SYSTEM AND METHOD FOR ELECTROPLATING AN OBJECTTECHNICAL FIELD

[0001] The present disclosure relates generally to electroplating technique. More particularly, it relates to a system and method for electroplating of objects.BACKGROUND

[0002] Electroplating is a common method used in manufacturing industries to coat a material with a layer of metal through an electrochemical reaction. This technique is widely used in the ornament industry, where it enhances the look, durability, and value of jewelry and decorative items. By applying a metal coating, electroplating improves the appearance of ornaments and makes them more resistant to rust and wear.

[0003] In recent years, the process of electroplating has undergone many changes, making it much more accurate and capable of working with a wider range of materials. However, the process used in the ornament industry is still mostly manual. This involves cleaning an object (which is to be plated), preparing the electrolyte solution, submerging the object in the solution while applying an electric current, keeping track of when to change the electrolyte solution, etc.

[0004] However, such process can cause manual errors such as skipping the steps involved in the process, using wrong configuration of electrolyte solution with the object, etc. Further, because the process is manual, the operator must manually determine the voltage and current to be applied to the electrolyte for plating, as well as the duration for which it is applied. This often results in either excessive or insufficient metal deposition on the object, leading to inconsistent results and increased labor costs.

[0005] Therefore, there is an increasing need to automate the process of electroplating to accurately determine the current and duration for which it is supplied to the electrolyte solution, ensuring the object is plated as per requirement.BRIEF DESCRIPTION OF ACCOMPANYING DRAWINGS

[0014] Other aspects, advantages, and salient features of the invention will become apparent to those skilled in the art from the following detailed description, which, taken in conjunction with the annexed drawings, discloses exemplary embodiments of the invention.DETAILED DESCRIPTION

[0015] The present disclosure describes a system and method for electroplating an object.

[0016] In the following description, for the purpose of explanation, specific details are set forth in order to provide an understanding of the present disclosure. It will be apparent, however, to one skilled in the art that the present disclosure may be practiced without these details. One skilled in the art will recognize that embodiments of the present disclosure, some of which are described below, may be incorporated into a number of systems.

[0017] However, the systems and methods are not limited to the specific embodiments described herein. Further, structures and devices shown in the figures are illustrative of exemplary embodiments of the presently disclosure and are meant to avoid obscuring of the presently disclosure.

[0018] It should be noted that the description merely illustrates the principles of the present invention. It will thus be appreciated that those skilled in the art will be able to devise various arrangements that, although not explicitly described herein, embody the principles of the present invention. Furthermore, all examples recited herein are principally intended expressly to be only for explanatory purposes to help the reader in understanding the principles of the invention and the concepts contributed by the inventor to furthering the art and are to be construed as being without limitation to such specifically recited examples and conditions. Moreover, all statements herein reciting principles, aspects, and embodiments of the invention, as well as specific examples thereof, are intended to encompass equivalents thereof.

[0019] Electroplating is a manufacturing process of using electrodeposition to coat an object with a layer of metal. In other words, a thin layer of metal atoms is deposited on another material / object through electrolysis. The metal added is known as a deposition metal, and the material or object on which the metal is deposited is known as a substrate material. In the electroplating process, a controlled electrolysis process is used to obtain desired metal coating.

[0020] In the electrolysis process, two metal rods are placed in an electrolyte (commonly also known as electrolyte chemical bath or electrolyte bath solution). The rods act as electrodes when connected to the opposite terminals of a battery or power supply to create a potential difference. The electric current causes the electrolyte bath to disintegrate into dissolved metal ions, and the positively charged metal ions deposit on the negative electrode (cathode), which causes plating of the object in a metal coating. These positively charged ions are part of the electrolyte. As they get deposited on the cathode, their concentration in the electrolyte reduces.Thereby, requiring replenishing of the concentration of the positive ions in the electrolyte.

[0021] This electrolysis process is widely used in the ornament industry, where it enhances the look, durability, and value of jewelry and decorative items. By applying a metal coating, electroplating improves the appearance of ornaments and makes them more resistant to rust and wear. However, such process can cause manual errors such as skipping the steps involved in the process, using wrong configuration of electrolyte solution with the object, etc. Further, because the process is manual, the operator must manually determine the voltage and current to be applied to the electrolyte for plating, as well as the duration for which it is applied. This often results in either excessive or insufficient metal deposition on the object, leading to inconsistent results and increased labor costs.

[0022] Therefore, there is an increasing need to automate this process to accurately determine the current and duration for the current to be supplied to the electrolyte, ensuring that the object is plated according as per requirement. Digitizing electroplating process would improve precision, consistency, and efficiency by automating control over important factors such as current density, plating time, and solution composition. This move towards automation would enhance product quality, reduce waste, and make production more efficient, aligning with current manufacturing trends and meeting the changing needs of the ornament industry.

[0023] In an embodiment, the present disclosure envisages a system and method for automating the electroplating of an object.

[0024] Figure 1 illustrates a system 100 for electroplating an object. The system 100 comprises at least an EMR database 102, a grouping device 104, a plating device 106, etc. Although the system 100 is depicted to include one or few components, that is, the EMR database 102, the grouping device 104, and the plating device 106 arranged in a particular arrangement in the present disclosure, the above-described components of the system 100 are merely illustrative and should not be taken to limit the scope of the present disclosure.

[0025] Various components of the system 100 such as the EMR database 102, the grouping device 104, the plating device 106 are communicably coupled to each other via a network. The network may include wired or wireless communication protocols. In an embodiment, the network may include, but not limited to a local area network LAN, a wide area network WAN (e.g., the Internet), a mobile network (for e.g., GSM (Global System for Mobile Communication), GPRS (General Packet Radio Service), EDGE (Enhanced Data for Global Evolution), etc.).

[0026] The EMR database 102 (hereafter referred to as ‘database’) acts as a centralized storage unit for storing data. The database 102 may include at least a processor, and a communication module to communicate with other devices such as the grouping device 104. The database 102 is configured to maintain records for multiple bags, where each bag is assigned a unique identification code. For every bag, the database stores details of the one or more objects 124 placed inside the bag, and along with information about the coating material to be used for plating those objects 124. The database 102 also stores technical charts of one or more coating materials. This bag identification code helps in inventory management and tracking of the bag throughout the electroplating process.

[0027] The details of the object 124 stored in the bag include but are not limited to type of object, size, weight, surface area, karat, colour, thickness, and material of the object, etc. In an exemplary embodiment, the object 124 can be an ornament such as ring, chain, or alike. In an exemplary embodiment, the thickness is a desired coating thickness, which is set by the user.

[0028] The technical chart of the coating materials stored in the memory includes but is not limited to characteristics of the coating materials for electroplating bath solution, such as current density of the coating material, cathode efficiency, electrolyte bath solution configuration, etc.

[0029] In an embodiment, the database 102 may be further communicably coupled with a computer system (not shown) for storing one or more details as defined above, but particularly not limited to the above defined details.

[0030] The grouping device 104 is communicably coupled to a scanner 108 for scanning the code provided on the bag and the database 102 for retrieving details of the object 124 and a coting material upon scanning the bag identification code. In an exemplary embodiment, the grouping device 104 in communication with the database 102, the grouping device 104 comprising: a scanner 108 configured to scan the bag identification code; a processor configured to, upon scanning of the bag identification code, retrieve from the database 102 the details of the objects in the bag and the coating material for coating the objects; a user interface 110 configured to receive user inputs indicative of a jig configuration for carrying the one or more objects 124; and a transmitter configured to transmit at least the jig configuration, the details of the objects 124 and the coating material. The detailed operation of the grouping device will be explained later in accordance with Figure 2. In one embodiment, the user also provides a desired coating thickness for the object. The desired coating thickness is also transmitted to the plating device for calculating a plating period for the object.

[0031] A plating device 106 in communication with the grouping device 104, the plating device 106 comprises: a receiver configured to receive at least the jig configuration, the details of the objects 124 and the coating material; a display configured to display at least the jig configuration, number of objects carried by the jig, and the coating material for plating the objects; a scanner 112 configured to scan a code affixed on an electrolyte bath container 116, the code indicative of an electrolyte 118 in said container 116; a rectifier 114 having a first terminal connected to an anode 122 disposed in the electrolyte bath container 116 and a second terminal connected to the jig 120, carrying at least one object 124, disposed in the electrolyte bath container 116; a processor configured to: upon scanning the code on the electrolyte bath container 116, match the electrolyte 118 with the coating material and generate an indication corresponding to the match result. For a positive match result, the processor determine a total current and a plating period for electroplating the object 124 based on at least surface area of the object 124 and the coating material; regulate the rectifier to supply the total determined currentthrough the terminals to the electrolyte for the determined plating period, and generate an acknowledgment indicating completion of plating. A detailed operation of the plating device 106 will described later in accordance with Figure 3.

[0032] Figure 2 illustrates a simplified block diagram of a grouping device 200, according to the present disclosure. It is noted that the grouping device 200 shown in Figure 2 corresponds to the grouping device 104 depicted in Figure 1, and is illustrated herein for further detailed explanation. The grouping device 200 comprises: a processor 202 for performing desired operation, input devices such as keys 204 and microphone 206, or the like, a communication module 208 for communicating with other devices such as a database 102 or a plating device 106, output devices such as a display 210 for displaying desired information to a user, an LED 212 and a speaker 214 for providing an indication to the user, or the like, a memory 216 for storing data and instruction to be performed by the processor 202, a power supply module 218 for supplying power to the device 200, and an I / O port 220 for communicating with other device such as but not limited to a scanner for scanning the bag identification code, a USB port for programming or debugging the device 200. It should be understood that the device 200 as illustrated and hereinafter described is merely illustrative, therefore it should not be taken to limit the scope of the present disclosure.

[0033] The processor 202 is capable of executing the machine executable instructions to perform the functions described herein. In an embodiment, the processor 202 may be implemented as a multi-core processor, a single core processor, or a combination of one or more multi-core processors and one or more single core processors. For example, the processor 202 may be embodied as one or more of various processing devices, such as a coprocessor, a microprocessor, a controller, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), a microcontroller unit (MCU), or the like.

[0034] In an aspect, the processor 202 is configured to, upon scanning the bag identification code through the scanner 108, retrieve from the database 102 the details of the objects 124 in the bag and the coating material for coating the objects 124. The bag is provided with a unique identification code. The code may be represented as a QR Code, Barcode, or alike. This code is the preconfigured identification number of the bag stored at the database 102. When a user (or operator) scans the bag identification code using the scanner 108, the grouping device 200 obtains details related to the bag along with a coating material detail which is to be used for the plating of object 124 in the bag. The grouping device also retrieves the technical chart of the coating material. These details are shown on the display 210 of the device 200 for user. It is to be noted here that the scanner is communicably coupled to the device 200 configured to scan the bag identification code.

[0035] After retrieving the details of the object 124, the device 200 receives user inputs for selection of a jig 120 and configuration of the jig 120. The jig 120 is a tool used for holding one or more objects 124 in the electrolyte bath 118. The user provide the jig 120 configuration for example a material of the jig 120 such as a copper or aluminum, type of jig 120 such as hook type or winding type, number of hooks in the jig 120, and a single or double wire jig 120, and a surface area of the Jig, or the like. In an embodiment, the hook type jig 120 has an exposed length of 2 inches and the winding type jig 120 has an exposed length of 18 inches. It is to be noted here that the exposed length means that the length of the jig 120 exposed to the electrolyte bath 118, for example, total length of the copper wire hook type jig 120 is dipped in the electrolyte bath 118 is 2 inches.

[0036] In another implementation, a user is provided with a plurality of predefined codes (hereinafter referred to as jig codes), each corresponding to a particular type of jig 120, such as a hook -type jig or a winding-type jig. It is noted here that the jig code can be affixed to the jig 124. When the user scans a jig code using the scanner 108, the grouping device retrieves corresponding details of the jig 124. The retrieved details include, for example, the surface area of the jig, an indication ofwhether the selected jig is a single-wire jig or a double-wire jig, and the material of the jig. In one embodiment, the user also provides a desired coating thickness for the object. The desired coating thickness is also transmitted to the plating device for calculating a plating period for the object.

[0037] Once the grouping device 200 obtains the details of the objects and the associated coating material, along with the jig configuration through the user interface, the processor 202 determines the number of objects 124 that can be mounted on the jig 120 based on the received jig configuration. After determining the capacity of the jig, the processor prepares a data packet containing information of the objects to be plated (for example, two objects) and transmits this data packet to the plating device 106 for initiating the electroplating process. The processor further generates a log record indicating the number of objects sent for plating and the number of remaining objects in the corresponding bag. For example, if a bag contains ten objects 124 and the jig configuration indicates that the jig 120 is of a hook type capable of carrying two objects, the processor prepares a data packet containing the details of the selected objects and the associated coating material. This data packet is then linked with the respective jig, identified by its jig code, and transmitted to the plating device 108 for electroplating. The processor also maintains a log by recording the number of objects sent for plating and the number of objects remaining in the bag. Maintaining such a log for each object facilitates accurate inventory management and enables traceability of each object throughout the electroplating process. In one embodiment, the desired coating thickness is provided by the user is also transmitted to the plating device for calculating a plating period for the object.

[0038] The grouping device 200 then displays subsequent processing steps to the user before the objects 124 are sent for plating. For example, the device 200 may display a cleaning and degreasing process step that the objects are required to undergo prior to electroplating. The display of the grouping device may also display information about the electrolyte bath solution. For example, the coating materialneeds to be used for plating the selected objects. In one embodiment, the cleaning process includes ultrasonic cleaning and degreasing of the objects.

[0039] After transmitting the details of the selected objects, the associated coating material, and the corresponding jig information to the plating device 106, the grouping device 200 is configured to receive an acknowledgment signal indicating completion of the plating process for the objects sent. The grouping device 200 includes a timer configured to record and store timestamps in the database 102 to track the electroplating process. Specifically, when the bag identification code is scanned, the timer records a first timestamp marking the initiation of the electroplating process. Upon receiving the acknowledgment signal indicating completion of the plating operation, the timer records a second time stamp corresponding to the completion time. These timestamps are stored in the datable log, thereby enabling traceability of each batch of objects 124 and facilitating monitoring of the process duration for quality control and process optimization.

[0040] Once the completion timestamp is recorded, the grouping device 200 updates the corresponding database record associated with the respective bag identification code. The processor 202 marks the plated objects as completed and updates the inventory status to reflect the reduced count of unplated objects within the bag. The updated data, including timestamps, plating status, and jig identifiers, is then transmitted to the database 102 for centralized storage and synchronization. This enables real-time monitoring of plating operations, process traceability across multiple stages, and generation of analytical reports for production efficiency and quality assurance purposes.

[0041] Figure 3 illustrates a plating device 300 according to the present disclosure. It is noted that the plating device 300 shown in Figure 2 corresponds to the plating device 106 depicted in Figure 1, and is illustrated herein for further detailed explanation. The plating device 106 or 300 forms apart of a system 100 configured for electroplating one or more objects 124 caried by the jig 120. As shown in Figure 1, the plating device 106 or 200 is operatively coupled with a grouping device 200,a scanner 112, a rectifier 114, and an electrolyte bath container 116 containing an electrolyte bath 118. The plating device 300 is configured to receive data from the grouping device 200 and automatically executes the electroplating process by controlling electrical parameters and monitoring bath conditions in real time. In another implementation, the plating device 300 may require user input for initiating the electroplating process.

[0042] In one embodiment, the plating device 300 comprises a processor 302 operatively coupled with multiple functional modules that enable process control and data communication. These modules include one or more input interfaces such as keys 304 and a microphone 306 for receiving operator commands, a communication module 308 for wired or wireless data exchange with the grouping device 200 and the database 102, and output components such as a display 310, LED indicator 312, and speaker 314 for visual and audio feedback. The device 300 further includes a memory 316 for storing operational data and instructions, a power supply module 318 for providing regulated electrical power, and an input / output interface 320 for connection with sensors and actuators. The processor 302 may be implemented as a microcontroller, digital signal processor, or embedded controller programmed to automate and monitor plating operations.

[0043] The communication module 308 receives a data packet from the grouping device 200 containing the jig 120 configuration details, details of the objects 124 such as number, size, surface area, and material, and coating material detail required for plating. Communication may be established through wired means such as RS-485 or Ethernet, or through wireless means including Bluetooth®, Wi-Fi®, or ZigBee®. Upon receiving the data, the processor 302 displays relevant information such as the jig type, number of objects, coating material, and preparatory instructions on the display 310. The LED 312 and speaker 314 provide indications corresponding to the device 300 states including “ready for plating,” “in progress,” “completed,” or “error.” In one embodiment, the data received from the grouping device includes the desired coating thickness for the object.

[0044] Before initiating the electroplating operation, the plating device 300 performs a verification process to ensure that the electrolyte bath 118 corresponds to the coating material designated for the selected objects 124. Each electrolyte bath container 116 is affixed with a predefined code, such as a barcode or a QR code, that uniquely identifies the container and specifies the type of coating material present in the electrolyte bath. When an operator scans the code using the scanner 112 of the plating device 300, the processor 302 retrieves the electrolyte identification data, including the coating material type associated with the scanned container. The processor 302 then compares this information with the coating material details received earlier from the grouping device 200 for the corresponding batch of objects. This cross-verification ensures that the electrolyte solution in the scanned container is same as the coating material intended for the plating process. If a mismatch or inconsistency is detected between the electrolyte bath type and the required coating material, the processor 302 immediately generates a warning message on the display of the plating device 300 and halts further operation to prevent an incorrect plating process. Upon confirmation of a valid match, the processor 302 authorizes initiation of the plating cycle and provides a confirmation indication to the operator through a display prompt or audible signal.

[0045] Once the electrolyte verification is successfully completed, the plating device 300 initiates control of the rectifier 114, which supplies the electrical energy necessary for the electroplating process. The rectifier 114 is operatively connected to the processor 302 and includes a first terminal coupled to an anode 122 disposed within the electrolyte bath 118 and a second terminal coupled to the j ig 120 carrying the one or more objects 124 to be plated, which is to be disposed withing the electrolyte bath 118. The rectifier 114 is integrated with a current sensor that continuously measures and regulates the current flowing through the terminals.

[0046] After verification of the electrolyte bath container 116 through the scanned code, the processor 302 of the plating device 300 determines a total plating current required for electroplating the one or more objects 124 carried by the jig 120. The processor 302 determines the total plating current based on the data received fromthe grouping device 200, which includes the total surface area of the objects, the area of the jig exposed within the electrolyte bath 118, and the type of coating material to be deposited. In addition to these parameters, the processor 302 retrieves from the database 102 the predefined technical characteristics corresponding to the coating material, such as the current density (A / dm2), cathode efficiency (deposition rate in mg / A min), and electrolyte bath capacity (expressed as grams per litter of metal concentration). These technical parameters are stored in association with each coating material’s technical chart within the database 102 and are utilized by the processor 302 to ensure accurate computation of plating parameters.

[0047] Based on the retrieved and received data, the processor 302 determines the total current required using the following relationship:Total Current (Ampere) = (Surface Area of Object + Exposed Jig Area) x Current Density x Time.

[0048] The total amount of metal deposition on the object is further computed as:

[0049] Total Deposition (mg) = Total Current x Cathode Efficiency.

[0050] The processor 302 then compares the computed total metal deposition with the predefined electrolyte bath capacity, which, in one embodiment, corresponds to a concentration of 2 grams per liter. This comparison allows the processor 302 to track the remaining concentration of coating metal in the electrolyte bath after each plating cycle and determine whether the concentration has dropped below a predetermined threshold.

[0051] In an exemplary embodiment, when the selected coating material is Rhodium, the plating device 106 operates as follows. The Rhodium solution has a current density of approximately 2 A / dm2and a cathode efficiency of 8 mg / A min, with a bath capacity of 2 g / L as defined in the Rhodium technical chart stored in the database 102. For a sample plating operation where the surface area of the obj ect is 1.5 dm2and the plating period in a non-limiting example is 10 minutes, theprocessor 302 computes the total plating current as 1.5 dm2x 2 A / dm2x 10 min = 30 Amp-min, resulting in a total metal deposition of 240 mg (30 Amp x 8 mg / Amin). Given a standard bath capacity of 4000 mg (2 g / L), the remaining concentration after this plating cycle is determined as 4000 mg - 240 mg = 3760 mg.

[0052] The plating device 300 defines a replenishment threshold corresponding to the depletion of up to 2 grams of coating material per liter, which in this example translates to consumption of approximately 1600 mg after several plating cycles. When the remaining metal concentration reaches the threshold level of 2400 mg / L, the processor 302 generates a replenishment indication, prompting the operator to restore the bath concentration. This indication may be provided through a visual alert on the display 310, illumination of the LED 312 indicator, or an audible signal through the speaker 314 integrated within the plating device 106. Upon receiving this indication, the operator replenishes the electrolyte bath solution by adding a proportional amount of metal salt (e.g., 1600 mg of Rhodium) to restore the bath concentration to its nominal capacity of 2 g / L.

[0053] In an exemplary embodiment, after each plating cycle, the processor 302 estimates the remaining concentration of the coating material in the electrolyte bath 118. This estimation is derived based on the total amount of metal deposited during the cycle, the predefined bath capacity, and the depletion rate of the coating material as defined in the corresponding technical chart stored in the database 102. When the calculated remaining concentration falls below a preset threshold such as a depletion of up to 2 grams of coating material per liter, the processor 302 automatically generates a replenishment indication. The indication is provided to the operator through one or more of the display 310, LED indicator 312, or audible alert from the speaker 314, prompting replenishment of the electrolyte bath solution with the required amount of coating material to restore the desired concentration. This automatic monitoring and alert mechanism ensures consistent plating quality and prevents undercoating or uneven deposition caused by electrolyte depletion.

[0054] This monitoring and control of electrolyte concentration ensures consistent plating quality, prevents over-depletion of coating material, and extends bath life through timely replenishment. Additionally, the plating device 106, in communication with the grouping device 200 and database 102, records and stores each plating cycle’s data, including total current applied, plating period, coating material consumption, and time of completion. Such data logging enables real-time inventory management of coating materials and provides complete traceability of each object throughout the electroplating process, thereby improving production efficiency, quality control, and auditability across multiple plating operations.

[0055] Upon completion of the plating cycle, the processor 302 of the plating device 300 generates an acknowledgment signal confirming successful completion of the electroplating process for the batch of objects 124 mounted on the jig 120. This acknowledgment signal is automatically transmitted to the grouping device 200. The acknowledgment serves as a process completion trigger for updating the records associated with the corresponding bag identification code. The grouping device 200 includes a timer configured to record and store timestamps in the database 102 to track the progress and duration of each electroplating cycle. When the bag identification code is initially scanned and transmitted to the plating device 300, the timer records a first timestamp, which marks the initiation of the electroplating process. Upon receipt of the acknowledgment signal from the plating device 300, the timer records a second timestamp, representing the completion time of the plating operation. Both timestamps are stored in the database 102 and linked to the respective bag identification record. This time-based logging mechanism enables traceability of every plating batch, allows verification of process duration against standard parameters, and assists in maintaining consistency and quality control across multiple plating cycles. Furthermore, the recorded timestamps can be utilized for historical analysis and performance analytics to optimize future plating operations.

[0056] The memory 316 of the plating device 300 stores operational parameters and process data including jig identifiers, coating material details, electrolyte bath code,current and voltage profiles, and completion acknowledgments. These data elements are used by the processor 302 to ensure accurate control of plating conditions and consistent coating quality across batches. The memory 316 also retains plating recipes, calibration data, and operational logs for traceability and diagnostic analysis. A power supply module 318 delivers regulated electrical energy to the processor 302, rectifier 114, and other modules to ensure stable operation during the plating cycle. The synchronized exchange of plating status, timestamps, and process data between the plating device 300 and grouping device 200 facilitates seamless automation, centralized data management, and end-to-end traceability of the electroplating workflow.

[0057] In accordance with the various embodiments, the present disclosure provides a method for electroplating of objects, implemented in a system comprising a database 102, a grouping device 200, and a plating device 300. The method enables automation and traceability of the electroplating process by integrating digital identification, process parameter control, and real-time monitoring of plating conditions. The method may be executed by the processor of the grouping device 104 and the plating device 106 in the system 100.

[0058] In one embodiment, the method includes storing, at the database 102, details for each of a plurality of bags containing one or more objects 124 intended for plating. Each bag is assigned a unique identification code, such as a two-dimensional barcode or QR code, which uniquely distinguishes the bag within the system. The stored details include at least the number of objects, the type and material of each object, the dimensions, surface area, and an associated coating material that is to be applied during the plating process. The database 102 further maintains reference data such as current density, cathode efficiency, and bath capacity of the coating materials obtained from their corresponding technical charts.

[0059] At the grouping device 104, the operator begins the plating process by scanning the bag identification code using a scanner 108. Upon scanning, the processor 202 of the grouping device 104 retrieves the corresponding record fromthe database 102, including the details of the object and the coating material information associated with the scanned bag. This retrieval ensures accurate association between the objects, their respective coating requirements, and subsequent process stages.

[0060] The grouping device 200 then receives user inputs through a touchscreen display or keypad, representing a jig configuration used for carrying the objects during plating. The jig configuration may include, but is not limited to, the type of jig (such as hook type or wire type), the number of hooks available for suspending objects, and the wire configuration. Based on these inputs, the processor 202 of the grouping device determines how many objects can be carried by the jig 120 for a given plating batch and prepares a data packet comprising the jig configuration, the details of the selected objects 124, and the coating material data.

[0061] The data packet is transmitted by the grouping device 104 to the plating device 106, which is configured to receive and display the transmitted information. Upon receipt, the plating device 106 displays on its display module 310 at least the jig configuration, the number of objects carried by the jig 120, and the coating material to be used, thereby confirming the plating parameters to the operator prior to initiation of the plating cycle.

[0062] Before the plating process begins, the plating device 106 scans a code affixed on the electrolyte bath container 116. Each container is labeled with a predefined code that uniquely identifies the type of electrolyte present in the container and the corresponding coating material it relates to. The processor 302 matches the scanned electrolyte code with the coating material data received from the grouping device 200. If a mismatch is detected, the processor 302 generates a warning message and halts further operation until corrective action is taken. If a valid match is confirmed, the processor 302 authorizes continuation of the process and generates a confirmation indication on the display 310.

[0063] For a positive match result, the processor 302 determines the total plating current and plating duration required to achieve uniform and accurate deposition ofthe coating material over the objects. The total plating current is computed based on the surface area of the objects 124, the exposed surface area of the jig, which is predefined for based on the type of the jig configuration, the current density of the selected coating material, the cathode efficiency (representing the deposition rate), and the bath capacity, which is predefined, for instance, as 2 grams per liter. The current density, cathode efficiency, and bath capacity are obtained from the coating material’s technical chart stored in the database 102. The processor thereby determines the required total current and plating period, ensuring precise control over plating quality and thickness. In an embodiment, the plating period is calculated based on a desired coating thickness, a current density of the coating material, a surface area of the object, and deposition rate (cathode efficiency).

[0064] The plating device 106 then regulates a rectifier 114 through control signals issued by the processor 302. The rectifier includes a first terminal connected to an anode within the electrolyte bath and a second terminal connected to the jig carrying the objects. The rectifier measures and controls the current passing through the electrolyte bath 118, maintaining a stable current corresponding to the coating material’s defined current density. The processor 302 continuously monitors current and voltage during plating and adjusts parameters or terminates the process if deviations from permissible limits are detected, ensuring safety and plating accuracy.

[0065] Before initiation of the electroplating, the grouping device 104 may also present cleaning instructions on the display module prior to plating. These cleaning instructions may include an ultrasonic cleaning and chemical degreasing step, ensuring the object surfaces are free from impurities or contaminants that could affect coating adhesion or uniformity. This guided cleaning sequence standardizes preparation steps across batches and reduces operator error.

[0066] A timer associated with the grouping device 104 records timestamps for process tracking. When the bag identification code is scanned and transmitted to the plating device 106, a first timestamp is stored in the database 102, marking theinitiation of the electroplating process. Upon completion of plating, when the acknowledgment signal is generated by the plating device 106, a second timestamp is recorded. These timestamps enable accurate tracking of process duration, assist in quality validation, and support traceability of each plated batch across the system.

[0067] After each plating cycle, the processor 302 of the plating device 106 estimates the remaining concentration of coating material in the electrolyte bath based on the total quantity of metal deposited and the known bath capacity. For example, if the coating material concentration decreases below a predetermined threshold, such as depletion to 2 grams per liter, the processor 302 triggers a replenishment alert via the display 310, LED 312, or speaker 314, prompting the operator to add the required quantity of metal salt to restore the bath concentration. This automated monitoring helps maintain the optimal chemical balance and enhances plating consistency.

[0068] Upon completion of the plating operation, the processor 302 generates an acknowledgment signal confirming successful plating. The acknowledgment is transmitted to the grouping device 104, which updates its system records, marking the plated objects as completed and reducing the count of unplated objects in the bag. The updated data, including jig identifiers, plating timestamps, and coating details, are transmitted to the database 102 for centralized storage and synchronization, ensuring real-time visibility of plating progress across the manufacturing line.

[0069] The described method enables complete digital traceability, process automation, and quality assurance throughout the electroplating workflow. By automating data retrieval, electrolyte verification, plating parameter computation, and bath monitoring, the system minimizes manual intervention, reduces human error, and ensures uniform coating quality. Furthermore, the integration of timestamp-based process logging and automatic electrolyte concentration estimation enhances production efficiency, predictive maintenance, and regulatory compliance.
