Description

Technical Field

[0001] This utility model belongs to the field of diamond wire saw manufacturing, and in particular relates to a device for automatically replenishing additives by scanning a code. Background Technology

[0002] Diamond wire saws are high-efficiency cutting tools that use metal wire as a base and adhere diamond abrasive to its surface through processes such as electroplating or resin bonding. With their excellent cutting capabilities and high precision, they are widely used in silicon wafer slicing in the solar energy field, sapphire processing in the LED field, and cutting of difficult-to-cut materials such as magnetic materials and silicon carbide, greatly promoting the development of the photovoltaic and semiconductor industries.

[0003] In the manufacturing process of diamond wire saws, the busbar preparation stage requires the selection of high-strength steel wire, which undergoes cleaning, degreasing, and rust removal to ensure a clean surface. Subsequently, diamond particles are fixed to the busbar using electroplating, resin bonding, or brazing processes; for resin bonding, a curing treatment is also required to enhance strength. After manufacturing, rigorous quality inspections are conducted, including wire diameter measurement, particle distribution detection, and tensile strength testing. Only qualified wires are wound and packaged to ensure product performance meets standards.

[0004] In the manufacturing process of diamond wire saws, electroplating is a process that uses electrochemical methods to deposit a metal coating on the surface of the workpiece. During the electroplating of diamond wire saws, adding additives to the electroplating bath can improve the coating quality, making the coating more uniform and delicate, and enhancing the adhesion between the coating and the diamond abrasive. However, the additive content changes as the electroplating process continues. Additive consumption is related to many factors, such as the plating bath temperature, current density, anode state, the amount of electricity passed, and the sulfuric acid content in the plating bath. Among these, plating bath temperature and the amount of electricity passed have a significant impact on additive consumption. Higher temperatures accelerate additive consumption; higher currents and longer durations also increase additive consumption, requiring continuous replenishment to ensure the stability of the electroplating process and the quality of the coating.

[0005] Currently, in the production of electroplated diamond wire saws, the traditional method of adding additives mainly relies on manual operation. However, manual additive addition has many drawbacks. Firstly, manual operation is inefficient. In modern large-scale production, frequent additive replenishment consumes a significant amount of manpower and time, severely impacting production progress. Secondly, manual addition is difficult to guarantee accuracy. Different operators may add different amounts, and even the same operator may add the same amount at different times, leading to unstable additive content in the electroplating solution and consequently affecting the consistency of the coating quality. Furthermore, manual operation is prone to errors, potentially resulting in excessive or insufficient addition. Excessive additive not only leads to waste but may also negatively impact the performance of the electroplating solution and the coating quality. Insufficient additive cannot meet the electroplating process's additive requirements, also resulting in a decline in coating quality, such as uneven coating and poor adhesion. Utility Model Content

[0006] The purpose of this invention is to provide a device for automatically replenishing additives by scanning a code, so as to solve the technical problem of unstable dosage when adding additives manually and to automate the addition of additives.

[0007] To achieve the above objectives, the specific technical solution of this utility model for an automatic additive replenishment device via barcode scanning is as follows:

[0008] An apparatus for automatically replenishing additives by scanning codes includes several storage tanks for storing various additives, a metering device installed at the outlet of the storage tanks, a barcode scanner for scanning the QR codes of the additives, and a controller.

[0009] The controller inputs preset process information through the input terminal, selects the corresponding liquid storage tank according to the scanning information fed back by the barcode scanner, and controls the metering device corresponding to the liquid storage tank to release additives according to the information in the preset process.

[0010] As a further improvement of this utility model, the controller is a PLC controller, and the input terminal is a touch screen structure. The touch screen structure is used to set various additive parameters in the preset process.

[0011] As a further improvement of this utility model, the controller includes a data storage module for storing preset process information and recording the use and addition of additives, which facilitates querying and traceability.

[0012] As a further improvement of this utility model, a liquid level sensor is provided inside the storage tank. The liquid level sensor provides real-time feedback to the controller on the liquid level information of the additive in the storage tank. The controller issues a reminder when the liquid level in the storage tank is lower than a preset height.

[0013] As a further improvement of this utility model, the device of this utility model also includes a mixing tank connected to the outlet side of the metering device, wherein the mixing tank mixes various additives and discharges them into the production process.

[0014] As a further improvement of this utility model, the mixing tank is equipped with a temperature sensor and a temperature control device connected to the controller, and the controller controls the mixing temperature in the mixing tank according to preset process requirements.

[0015] As a further improvement of this utility model, the mixing tank is provided with a stirring device connected to the controller, and the controller controls the stirring speed of the stirring device according to a preset process.

[0016] As a further improvement of this utility model, the barcode scanner and the controller are connected via a wireless network.

[0017] As a further improvement of this utility model, the metering device is a peristaltic pump.

[0018] Beneficial effects:

[0019] This invention's device features multiple storage tanks for storing different types of additives. Combined with metering devices located at the outlets of these tanks, it provides the hardware foundation for precise additive replenishment. The introduction of a barcode scanner is key to achieving precise control; by scanning the additive's QR code, additive information can be quickly and accurately obtained. The controller, acting as the "brain" of the entire device, can input preset process information via its input terminal and, based on the scanning information from the barcode scanner, quickly identify and select the corresponding storage tank. It then controls the metering device corresponding to that tank, strictly releasing the additive according to the parameters required in the preset process. This precise control mode, compared to the unstable additive replenishment caused by human error during traditional manual addition, ensures that the additive concentration in the electroplating solution remains at an ideal level, thereby effectively improving plating quality and guaranteeing product consistency and stability.

[0020] In terms of automation and improved production efficiency, this device completely eliminates the tedious process of frequent manual additive addition. Operators only need to scan the code and input preset process information; subsequent operations such as additive identification, selection, and quantitative release are all automatically completed by the device. This not only significantly reduces manual labor and greatly improves additive replenishment efficiency, but also avoids potential oversights and errors during manual operation, reducing human interference in the production process. In modern large-scale production, this automated operation enables rapid and continuous additive replenishment, greatly improving overall production efficiency, meeting the demands of large-scale, high-efficiency production, and powerfully promoting the automation of manufacturing.

[0021] In summary, this patented device, with its precise control capabilities and efficient automated operation, effectively solves the key problems of low efficiency and poor accuracy in traditional additive replenishment methods, bringing a more reliable and efficient solution to related production fields. It has extremely high practical value and broad market application prospects. Attached Figure Description

[0023] The markings in the diagram are as follows: 1. Storage tank; 2. Metering device; 3. Barcode scanner; 4. Controller; 41. Input terminal; 5. Mixing tank. Detailed Implementation

[0024] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0025] Implementation example:

[0026] like Figure 1 As shown, a device for automatically replenishing additives by scanning QR codes uses a barcode scanner 3 to scan the QR codes of corresponding additives to replenish the additives in the electroplating tank. The additives include various auxiliary materials such as dispersants, stress relievers, leveling agents, brighteners, and pH adjusters. Different QR codes are created for different categories of additives and affixed near the operating table. In this embodiment, the barcode scanner 3 uses a barcode gun wirelessly connected to a controller 4, providing real-time feedback of the scanning information to the controller 4. Simultaneously, the QR codes also provide trade secret protection for the additive components.

[0027] In this implementation, controller 4 is a PLC controller, and input terminal 41 is a touch screen. Operators input electroplating process information via the touch screen, including parameters such as the type and amount of additives required, mixing temperature, and stirring speed. At the beginning of the electroplating process, additives are added by scanning the QR codes of various additives. After a period of electroplating, the need for replenishment of various additives is determined by changes in the composition of the electroplating solution, fluctuations in process parameters, or the operating status of the equipment. For example, reduced foaming on the surface of the electroplating solution and poor dispersibility (insufficient dispersant); cracks, roughness, or stress concentration in the coating (insufficient stress reliever or leveling agent); decreased gloss and graying of the coating (insufficient brightener), etc. Throughout the additive replenishment process, the controller's data storage module automatically records detailed data such as the name of the additive, addition time, addition amount, mixing temperature, stirring speed, and operator information. This data provides important information for quality traceability, process optimization, and production management. Operators can query historical records or export data for analysis at any time via the touch screen.

[0028] A liquid level sensor is installed inside the storage tank 1. The liquid level sensor provides real-time feedback to the controller regarding the liquid level of the additives in the storage tank 1. When the liquid level is lower than the preset height, a signal indicating that replenishment is needed will be displayed on the touch screen. The alarm signal will disappear after replenishment is made to the storage tank 1. The metering device 2 uses a peristaltic pump, which is installed at the opening of each storage tank 1. It controls the release rate of the additives according to the signal from the controller 4. The additives discharged by the peristaltic pump enter the mixing tank 5. Additives that need to be mixed are stirred in the mixing tank 5 and then discharged into the electroplating tank. Additives that can be used directly can be discharged directly into the electroplating tank through the mixing tank 5. The additives in the mixing tank 5 are heated by a temperature control device. The temperature sensor provides real-time feedback of the temperature information to the controller 4. The temperature control device heats the mixing tank according to the temperature parameters set by the controller 5, adjusting the temperature inside the tank to a suitable range. At the same time, the stirring device starts at a preset stirring speed to stir the additives in the tank, ensuring that the various additives are fully mixed and uniform, thus guaranteeing the quality of the additive mixture.

[0029] Compared to traditional manual additive addition, this device eliminates the need for dedicated personnel, saving labor costs. Manual addition has a significant error rate, while this device, through a peristaltic pump and closed-loop control system, can control the error within ±0.5%. This device keeps additive concentration fluctuations within ±1%, compared to ±5% fluctuations in traditional processes, reducing coating thickness deviation from ±1μm to ±0.3μm, significantly improving the cutting accuracy and lifespan of diamond wire saws. The data storage module records the usage of each batch of additives, and combined with barcode traceability, it further reduces performance differences between batches, meeting the stringent consistency requirements of high-end customers. Meanwhile, traditional manual addition requires frequent opening of the storage tank, posing a risk of operator contact with strong acid and alkali additives. This device operates in a fully enclosed manner, reducing manual operation and avoiding the risk of chemical leakage. The barcode scanner reads electronic QR codes instead of traditional paper work orders, reducing transcription errors and greatly improving the efficiency of production instruction transmission.
