Description

Technical Field

[0001] The present invention relates to the field of semiconductor equipment communication, in particular to the field of SMT material throwing technology, and specifically to a real-time monitoring system for SMT material throwing. Background Art

[0002] SMT production lines, with their high precision, high speed, and high density, play a vital role in the production of electronic products. However, with the accelerating pace of product updates and increasing demand for personalized products, traditional manual monitoring and management methods are no longer able to meet the needs of modern production.

[0003] In semiconductor memory chip manufacturing, chip placement machine material loss is a significant problem, impacting both production efficiency and costs. To address this issue, it's crucial to thoroughly understand the causes of material loss and implement appropriate solutions. These include nozzle issues, recognition system issues, positioning issues, vacuum issues, program issues, incoming material issues, and feeder issues.

[0004] However, existing production lines cannot monitor material discard in real time. Alarms are triggered only when the material exceeds a threshold. This increases the probability of defects, impacting equipment efficiency and product quality. When equipment anomalies occur, traditional methods rely on manual inspections or passive problem detection. Fault location and resolution take a long time, often leading to extended downtime and increased production capacity loss. SMT production line quality control spans multiple links, and traditional manual recording methods make it difficult to trace the source and point of responsibility for defective products, impacting the efficiency of quality improvement. With a wide variety of production equipment and complex production line processes, managers lack real-time data and comprehensive analysis, making it difficult to optimize production capacity and adjust production strategies in a timely manner.

[0005] Therefore, to address these issues, comprehensive measures are needed from multiple perspectives. For example, regular equipment inspection and maintenance, optimized program settings, enhanced incoming material inspection, and close communication with suppliers can effectively reduce the material rejection rate, improve production efficiency, and reduce production costs. Therefore, real-time monitoring of material rejection is crucial, and the development of a material rejection monitoring system is particularly necessary. Summary of the Invention

[0006] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a real-time monitoring system for SMT material throwing, so as to solve the difficulties of the prior art.

[0007] To achieve the above-mentioned and other related purposes, the present invention provides a real-time monitoring system for SMT material throwing, comprising:

[0008] A data acquisition unit is installed on the placement machine and is connected to the production management system through sensors and interfaces within the data acquisition unit to obtain the equipment's operating status, production quantity, and fault information;

[0017] According to the preferred solution, the data collection unit collects the number of mounted components, the mounting speed, and whether material throwing occurs.

[0018] According to the preferred solution, different colors are used in the production board to represent different production statuses.

[0019] According to the preferred solution, green is set in the production dashboard to indicate normal production, yellow indicates that the order is about to be completed but there may be minor problems, and red indicates that production is stagnant or a serious failure occurs.

[0020] According to the preferred solution, the warning threshold is configured separately in the warning and adjustment module.

[0021] The present invention provides real-time monitoring of the material throwing data of the current production equipment through the data acquisition module, which makes it convenient for engineers to grasp the material throwing situation of the equipment in real time.

[0027] The present invention provides a real-time monitoring system for SMT material throwing, which is used in the memory stick production process. The present invention does not limit the type of memory stick, but the real-time monitoring system for SMT material throwing is particularly suitable for the material throwing process.

[0028] In general, the SMT material throwing real-time monitoring system proposed by the present invention mainly includes a data acquisition unit, a production dashboard, an early warning and adjustment module, and a controller. Figure 1 , which shows the layout relationship between the data acquisition unit, production dashboard, early warning and adjustment module, and controller.

[0029] In order to achieve the purpose of real-time monitoring of material throwing, the existing production lines in the background technology cannot achieve real-time monitoring of material throwing. They can only alarm when the value exceeds the limit, resulting in a high probability of defects, affecting equipment efficiency and product quality. When equipment anomalies occur, the traditional model relies on manual inspections or passive problem discovery, which takes a long time to locate and handle the fault, often resulting in extended downtime and increased production capacity loss. SMT production line quality control runs through multiple links. The traditional manual recording method makes it difficult to trace the source and responsibility of defective products, which affects the efficiency of quality improvement. The production equipment is diverse and the production line process is complex. Managers lack real-time data and comprehensive analysis, making it difficult to optimize production capacity and adjust production strategies in a timely manner. Therefore, in the technical solution provided by this embodiment, the data acquisition module provides real-time monitoring of the material throwing data of the current production equipment, allowing engineers to understand the material throwing situation of the equipment in real time. When the material throwing data reaches a certain level, it will drive the controller to sound and light alarms. Combined with the shutdown module, it can also realize the function of shutting down the equipment when the alarm value is reached, thereby minimizing the losses caused by material throwing. In addition, the historical data module uses big data storage to achieve the purpose of permanently retaining all material throwing data and making it available to users for analysis at any time.

[0030] Specifically, such as Figure 1 As shown, the data acquisition unit is installed on key equipment on the SMT production line, such as the placement machine. It is connected to the production management system through the sensors and interfaces in the data acquisition unit to obtain data such as the equipment's operating status, production quantity, fault information, etc. For example, the placement machine can provide real-time feedback on the number of components placed, placement speed, whether material throwing occurs, etc., and summarize and display the real-time material throwing information of the current production line from multiple angles such as time, position, and components. Technical engineers can use this function to understand the material throwing situation of the equipment in real time.

[0031] Next, the production kanban is electrically connected to the output end of the data acquisition unit and displays the production progress information collected by the data acquisition unit. The data acquisition unit is set on each production line, and the data of the data acquisition unit are transmitted and fed back on the same production kanban. The kanban function of the production management system is used to display the production progress of the SMT computer motherboard with an intuitive graphical interface; different colors can be set to represent different production status, such as green for normal production, yellow for orders that are about to be completed but there may be minor problems, and red for production stagnation or serious failures. In addition, managers can quickly understand the operation status of the entire production line through the kanban.

[0032] As mentioned above, there is also an early warning and adjustment module that sets an early warning threshold for production progress, determines whether the data obtained in the data acquisition unit is abnormal in terms of material throwing, and issues an alarm in time; in the production management process, for some common materials, we can set a fixed threshold, such as 1%, and when it exceeds 1%, the system will alarm and remind relevant personnel; but for some special precious materials (such as chips), such materials cannot be managed in proportion. According to general management requirements, an alarm will be issued immediately after a material is thrown, and the operator will be required to recycle the thrown materials and use them again. This kind of material control requirement is very high, and there can be no loss. The system provided in this embodiment can separately configure the throwing value of this material number for monitoring. After monitoring the throwing of a specific material, an alarm will be issued immediately, and the track locking can be used to force the shutdown to minimize the loss.

[0033] On this basis, the controller receives the material throwing data collected from the data acquisition unit and realizes progress tracking at the same time, such as real-time monitoring of fault processing. When the material throwing data reaches a certain level, it will drive the controller to sound and light alarm. Combined with the shutdown module, it can also realize the function of shutting down the equipment after reaching the alarm value, thereby minimizing the losses caused by material throwing.

[0034] In addition, the data acquisition unit and the historical data module transmit and permanently store data. When the leader needs to compile statistics on the material loss in the last half month or half a year as a report, most placement machines cannot save long-term data due to limited hard disk space capacity. Generally, they save data for 1 month. If you need to query data from earlier times, you cannot do so. Our software is equipped with a separate server and database, which can permanently store the material loss. Different equipment and different production lines can be saved together. If there is a need for subsequent analysis, these data can be easily queried in the system. The system supports various tools such as Pareto charts, bar charts, line charts, SPC, etc. for material loss analysis.

[0035] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
