Description

Technical Field

[0001] The present invention relates to the field of intelligent warehousing technology, and in particular to a method for storing and accessing semiconductor gold wire boxes, which realizes efficient, accurate and safe automated storage and circulation management. Background Art

[0002] The present invention relates to the field of intelligent warehousing technology, and more specifically, to a method for storing and accessing semiconductor gold wire boxes. Semiconductor gold wire, a key material in semiconductor manufacturing, has a direct impact on production efficiency and product quality through its storage and circulation management. With the rapid development of the semiconductor industry, the requirements for intelligent, automated, and secure gold wire storage systems are increasing. Traditional gold wire storage methods have gradually shifted toward intelligent management, involving technologies such as automated shelving, robotic handling, sensor monitoring, and safety protection.

[0003] In recent years, the application of intelligent warehousing technology in the semiconductor industry has become increasingly widespread. By integrating automated equipment with information management systems, efficient material storage and precise sorting have been achieved. However, existing warehousing systems still have shortcomings in storage efficiency, operational accuracy, transmission consistency, and security management, making it difficult to fully meet the requirements for the refined management of high-value semiconductor gold wire materials. The development direction of intelligent warehousing technology is to improve system integration, operational accuracy, and security to meet the high efficiency and high reliability requirements of semiconductor manufacturing and provide better solutions for the management of high-value materials.

[0004] In the existing technology, the storage of semiconductor gold wires mostly adopts a combination of fixed shelves and manual operations. Although this method is simple to operate, it has significant defects. Manual sorting efficiency is low, especially in a high-intensity production environment, it is easy to cause sorting errors due to human error, affecting the continuity of the production process. In addition, traditional shelves usually adopt a single-aisle structure, with limited space utilization and a lack of a flexible caching mechanism, resulting in a slow material turnover rate and difficulty in adapting to rapid production needs. In terms of the transmission system, the existing technology mostly uses a simple belt conveyor device, which lacks a direction calibration function. The gold wire box is prone to directional deviation during the transmission process, which increases the complexity of subsequent operations. There are also deficiencies in the weighing and verification link. Some systems are not equipped with automated weighing devices and need to rely on manual inspection. Not only is it inefficient, but it is also easy to cause quality problems due to weight errors, affecting the accuracy of the gold wire usage and the traceability of product quality.

[0005] In response to the problem of sorting accuracy, some systems in the existing technology have introduced indicator lights or simple sensor auxiliary devices to guide operators to find the target materials. However, the functions of these devices are relatively simple. For example, the indicator light can only mark the approximate location and lacks precise visual guidance. Operators still need to spend time confirming the location of the material. The application of sensors is also relatively rudimentary. They can usually only detect whether the material exists, but cannot determine in real time whether the sorting operation is completed, making it difficult to form closed-loop management. In addition, most existing sorting assistance systems are single functional modules and lack the integration of multiple auxiliary mechanisms, resulting in limited effects in high-precision sorting scenarios. In particular, in complex production tasks, the system response speed and accuracy are difficult to meet the requirements. This singleness limits the application effect of the system in the management of high-value materials.

[0006] In terms of security management, existing gold wire storage systems typically rely on simple physical locks or single access control, which makes it difficult to effectively prevent unauthorized operation or material loss. While some systems are equipped with monitoring devices, these are mostly post-event recording functions and lack real-time alarm and linkage mechanisms. In the event of abnormal operation, such as excessive or insufficient gold wire boxes being taken, the system is unable to detect and notify management personnel in a timely manner, posing a safety hazard. Furthermore, existing safety protection devices are mostly concentrated in storage areas, with insufficient monitoring of transmission and sorting areas, which can easily lead to management loopholes in the material flow process. For high-value materials such as semiconductor gold wire, insufficient security protection can lead to serious economic losses and limit system reliability.

[0007] To address these issues, existing technologies have implemented several improvements. Some systems have introduced robotic arms to replace manual handling, improving storage and transport efficiency; some rack designs employ dual-aisle structures to increase space utilization; and some systems have enhanced detection capabilities by increasing the number of sensors. However, these improvements have not fully addressed the issues of low sorting accuracy, inconsistent transport directions, and inadequate safety management. For example, while the introduction of robotic arms has improved handling efficiency, their clamping mechanism lacks the adaptability to accommodate wire cassettes of varying sizes, resulting in insufficient operational precision. While dual-aisle racking has increased storage capacity, it has not effectively addressed the issue of wire cassettes slipping. While increasing the number of sensors has improved detection capabilities, it lacks a systematic closed-loop management framework, resulting in limited improvements in operational efficiency and accuracy. Regarding safety, some systems have introduced light barriers or simple alarms, but their functionality is limited to a single area, failing to provide comprehensive monitoring and protection throughout the entire process and failing to meet the demands of refined management of high-value materials.

[0008] This application aims to address the shortcomings of the existing semiconductor gold wire box storage and access methods in terms of storage efficiency, operation accuracy, transmission direction consistency and safety management, and to design an access method that integrates dual-lane storage, precise handling, automated transmission and weighing verification, and multiple safety protections to improve the efficiency, accuracy and safety of gold wire box storage and circulation. Summary of the Invention

Those skilled in the art will understand the specific meanings of these terms in the present invention. The present invention is further described below with reference to the accompanying drawings.

[0053] The present invention provides a method for storing and accessing semiconductor gold wire boxes, which is applied to intelligent storage systems. By integrating dual-aisle shelves, aisle manipulators, sorting auxiliary devices and safety protection devices, efficient, accurate and safe storage and access of gold wire boxes can be achieved. Figure 1 The overall layout of the system includes shelf 1, lane manipulator 2, sorting auxiliary device 3 and safety protection device. Shelf 1 is used to store gold wire boxes. Lane manipulator 2 moves gold wire boxes in the lane of shelf 1. Sorting auxiliary device 3 is set at the lane exit to transfer and verify gold wire boxes. Safety protection device monitors the operation area and manages access rights. Shelf 1 adopts a double-lane structure. Storage slots 4 are neatly arranged in a matrix formed by the columns and beams of shelf 1. Sensors are embedded in the bottom of storage slots 4 to detect the placement status of gold wire boxes. Fixed side guards are set on the side walls of the lane to prevent gold wire boxes from sliding. Figure 2 As shown. The lane manipulator 2 drives the clamping mechanism 6 through the servo motor 5, sliding along the track to adapt to the sidewall, and performs the clamping and placement of the gold wire box. The sorting auxiliary device 3 includes a conveying rotary mechanism 7 and an automatic weighing device 11. The conveying rotary mechanism 7 transmits and adjusts the direction of the gold wire box through the belt 8 and the rotary motor 10. The automatic weighing device 11 verifies the weight using a high-precision electronic scale 12. Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The safety protection device includes a safety grating 14, an access control device 13 and an alarm linkage device to ensure operational safety and authority management, such as Figure 1 and Figure 7 shown.

[0054] The dual-lane structure of the rack 1 is connected by columns and beams to form a stable matrix. The storage slots 4 are designed as rectangular troughs with dimensions suitable for wire boxes to ensure stable storage. An LED indicator light is fixed to the side wall of each storage slot 4, fixed by bolts and electrically connected to the sensor. The indicator signal is triggered synchronously based on the sensor detection results to indicate the location of the target wire box. A laser projection light source is fixed to the top of the lane. The laser transmitter projects a positioning light on the target storage slot 4 to assist the lane manipulator 2 in precise positioning, such as Figure 2 As shown. The sensor is embedded in the bottom of the storage tank 4, and detects the placement status of the gold wire box through electrical signals. If the scheduled sorting operation is not completed, the LED prompt light will be triggered to flash, indicating abnormal operation. The base of the tunnel manipulator 2 is fixed with a servo motor 5, which drives the clamping mechanism 6 through a rotation connection. The clamping mechanism 6 is an adjustable clamping claw that is suitable for gold wire boxes of different specifications to ensure stable clamping. The servo motor 5 controls the horizontal and vertical movement of the clamping mechanism 6 in the tunnel, slides along the track and adapts to the sidewall to complete the transportation of the gold wire box from the storage tank 4 to the tunnel exit. During the transportation process, the clamping mechanism 6 is precisely controlled by the servo motor 5 to ensure the smooth transportation of the gold wire box and reduce the risk of material damage.

[0055] The sorting auxiliary device 3 is set at the exit of the shelf 1 aisle. The frame 9 is built with metal profiles to provide stable support for the conveying rotation mechanism 7 and the automatic weighing device 11. Figure 3 and Figure 6 The transmission rotating mechanism 7 includes a belt 8 and a rotary motor 10. The belt 8 wraps around the roller and the transmission shaft to form the bearing surface of the gold wire box. The rotary motor 10 is fixed to the side of the frame 9 and drives the belt 8 to circulate. At the same time, the direction of the gold wire box on the belt 8 is adjusted by rotating the connection to ensure that the direction marks are consistent, as shown in the figure. Figure 4 As shown. After the gold wire box is placed in the positioning slot block of the belt 8 by the lane manipulator 2, it is transported along the belt 8 to the sorting platform. The automatic weighing device 11 is installed at the bottom of the output end of the conveying rotating mechanism 7, which includes a high-precision electronic scale 12 and a data processing module, as shown. Figure 5 As shown in the figure, a high-precision electronic scale 12 cooperates with the belt 8 via a lifting mechanism. When the gold wire box is transferred above it, the lifting mechanism lifts the high-precision electronic scale 12 and passes it through the gap in the belt 8, allowing the weight of the gold wire box to be carried by the high-precision electronic scale 12, completing the weighing. The weighing data is transmitted to the data processing module via an electrical connection and compared with the preset standard weight. If the threshold is exceeded, an alarm signal is triggered. After weighing is completed, the lifting mechanism descends, the high-precision electronic scale 12 resets, and the gold wire box continues to be transferred along the belt 8.

[0056] The safety protection device works together through the safety grating 14, the access control device 13 and the alarm linkage device to ensure the safety of the operation area. The safety grating 14 is symmetrically fixed on both sides of the entrance of the sorting area and the transmission area. Multiple infrared transmitters and receivers form a detection light curtain covering the entrance, such as Figure 1 and Figure 7 As shown. When the light curtain is blocked, the safety light grid 14 triggers the alarm linkage device through an electrical connection, activates the sound and light alarm and notifies the security management personnel through the communication module via the wireless network. The access control device 13 is installed at the entrance of the storage area and adopts a combination of a double password lock and a fingerprint recognition module. The double password lock includes a digital password input panel and an embedded fingerprint recognition module, which is coupled to the alarm linkage device through an electrical connection. The operator needs to enter the correct password and unlock the electronic part through fingerprint verification, and then use the physical key to open the mechanical lock to complete the access control. If an unauthorized attempt is detected, the alarm linkage device records the abnormality and notifies the management personnel. The sound and light alarm of the alarm linkage device is fixed on the top of the entrance to the storage area, and emits sound and light alarms in real time. The communication module transmits the abnormal information to the security management system through the wireless network.

[0057] During the circulation of the gold wire boxes, a barcode scanning camera, fixed to the frame 9 of the sorting auxiliary device 3, scans the gold wire box's unique identification code, associates the identification information with the sensor detection data and the weight data from the high-precision electronic scale 12, and records it in the central control system. Based on the storage slot 4 occupancy information and target location, the central control system optimizes the movement path of the lane robot 2 to reduce handling time. Sensors detect the placement and removal status of the gold wire boxes and trigger prompt signals to ensure closed-loop management. The automatic weighing device 11 verifies the weight to ensure the accuracy of the usage and the traceability of the product quality. The safety grating 14 and access control device 13 monitor the operating area in real time to prevent unauthorized operation. The alarm linkage device responds to abnormalities in a timely manner, improving the safety of high-value gold wire materials.

[0058] This method improves storage space utilization through the dual-aisle shelf 1. The sidewall design is combined with sensors and precise handling of the aisle manipulator 2 to solve the problems of low storage efficiency and poor operating accuracy. The transmission rotation mechanism 7 ensures the consistency of the direction of the gold wire box, and the automatic weighing device 11 verifies the weight, eliminating the problems of inconsistent transmission direction and weight error. The multi-level protection of the safety grating 14, the access control device 13 and the alarm linkage device, combined with the closed-loop data management of the code scanning camera, solves the problem of insufficient security management, realizes efficient, accurate and safe storage and access of semiconductor gold wire boxes, and meets the semiconductor industry's demand for refined management of high-value materials. Reference Figures 1 to 7 The various components of the system work together, with a compact structure and integrated functions, which significantly improves access efficiency, accuracy and safety.

[0059] Through the coordinated work of the above devices, the entire process of automated and intelligent gold wire box transportation is realized. The specific steps are as follows.

[0060] Step 1: Storing and Retrieving Gold Wire Cartridges. Semiconductor gold wire cartridges are stored in a dual-lane rack structure consisting of multiple rectangular storage slots. Pressure sensors embedded in the bottom of each slot monitor the storage status of the cartridges in real time. A lane manipulator, located within the rack lanes, comprises a base, a servo motor, and a clamping mechanism. The clamping mechanism consists of two adjustable jaws, driven by a servo motor and capable of horizontal and vertical movement along the lane tracks to precisely pick up and place the cartridges. During storage, the clamping mechanism precisely places the cartridges in designated slots. During retrieval, the clamping mechanism accurately grasps the target cartridge according to instructions from the central control system.

[0061] Step 2: Manipulator Handling: Driven by a servo motor, the manipulator smoothly slides the gripped wire cassette along the aisle track to the sorting aid. The gripping mechanism is designed to fit the shelf's sidewalls, preventing the cassette from slipping or being damaged during transport, ensuring stable and reliable handling.

[0062] Step 3: Automatic Direction Alignment and Transport Sorting Assistance. The conveyor rotary mechanism consists of a belt, a rotary motor, and a positioning slot. After the robot places the wire cassette in the positioning slot on the belt, the rotary motor drives the belt and adjusts the direction of the cassette through a rotating connection. This ensures uniform direction markings on all cassettes, avoiding errors caused by manual alignment and simplifying subsequent operations.

[0063] Step 4: Automatic Weighing Verification. An automatic weighing device is installed at the output end of the conveyor and rotary mechanism, consisting of a high-precision electronic scale, a lifting mechanism, and a data processing module. After the wire box is conveyed to the automatic weighing device, the lifting mechanism lifts the high-precision electronic scale, which then passes through the gap in the belt to lift the wire box for weighing. The weighing data is transmitted to the data processing module in real time and compared with the preset standard weight. If the error exceeds the allowable error range, an alarm is automatically triggered to ensure the accuracy of the wire box usage and the traceability of its quality. After weighing is completed, the lifting mechanism descends, the electronic scale resets, and the wire box continues along the belt to the next process step.

[0064] Step 5: Multiple security protections The security protection device includes a safety light grid, an access control device and an alarm linkage device to achieve safety management of the entire process. The safety light grid is set on both sides of the entrance to the sorting and transmission area, and multiple infrared transmitters and receivers are used to form a detection light curtain. Once the light curtain is abnormally blocked, the safety light grid immediately triggers the sound and light alarm, and transmits the abnormal information to the management personnel in real time through the wireless communication module. The access control device is installed at the entrance of the storage area and adopts a double password lock (digital password and physical key) and a fingerprint recognition module. The operator needs to pass the triple verification of digital password, fingerprint recognition and physical key to open the access control, ensuring that only authorized personnel enter and preventing unauthorized operation. The communication module of the alarm linkage device supports 4G and Wi-Fi networks. The abnormal information is transmitted to the security management system as soon as possible, and the management personnel can respond and take measures in time to effectively prevent the loss or damage of materials.

[0065] Step 6: Scanning Data Correlation and Closed-Loop Management: A scanning camera mounted on the sorting aid frame scans the unique identification code on the wire cassettes. This information is correlated with pressure sensor detection data and high-precision electronic scale weighing data and recorded in the central control system, enabling closed-loop management of material storage and retrieval status. By analyzing storage slot occupancy and the target location of the wire cassettes, the central control system intelligently optimizes the movement path of the aisle manipulator, reducing material handling time and significantly improving operational efficiency.
