Description

Technical Field

[0001] This utility model relates to the field of precious metal recycling technology in electroplating production lines for semiconductor leadframe manufacturing, and in particular to an automatic control and real-time monitoring system for the recycling of precious metal silver on a spiral electroplating line for leadframes. Background Technology

[0002] Currently, in the production of semiconductor lead frames, silver is plated on the electroplating line. After silver plating, the product needs to be washed with water according to process requirements. The wastewater after washing is generally collected and treated through a washing tank. The common methods for treating washing wastewater are: 1. Directly discharging it to a treatment plant for wastewater treatment; 2. Manually collecting, concentrating, and reusing precious metals such as silver in the washing wastewater; 3. Semi-automatic collecting, concentrating, and reusing precious metals such as silver in the washing wastewater. However, there are many problems with the above-mentioned methods of collecting and recycling washing wastewater, as follows: (1) Directly treating it as wastewater results in a serious waste of precious metals, and the wastewater treatment cost is extremely high in order to meet the discharge standards; (2) Using manual collection and recycling methods or semi-automatic collection and recycling methods wastes labor costs and is inefficient. (3) Especially when there are multiple electroplating lines and multiple recycling systems (generally one electroplating machine is equipped with one recycling system), joint control cannot be achieved. In addition, electroplating machines are large-scale equipment with a huge footprint, requiring a lot of manpower for operation and inspection, resulting in extremely high recycling costs. (4) Since each set of collection and recycling tank equipment does not have a unified system operating system, it is not possible to conduct synchronous real-time monitoring and surveillance of all collection and recycling tank equipment, thus making it impossible to monitor and handle the real-time production situation, and production problems are not easy to detect. (5) Since multiple sets of equipment cannot be operated synchronously, intelligent automation cannot be achieved, resulting in low overall efficiency of precious metal recycling.

[0003] Therefore, it is necessary to improve the existing technologies for collecting and recycling precious metal silver on electroplating lines to achieve efficient and rapid precious metal recycling, thereby addressing the problems of the existing technologies. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic control real-time monitoring system for silver recycling in lead frame coil electroplating lines. This system employs a PLC + touchscreen automation control method, enabling real-time monitoring of all precious metal silver collection and recycling units on the electroplating production line. It features daily recycling time setting, runtime setting, manual / automatic operation, dynamic operation display, and protection function settings. It can simultaneously control multiple collection and recycling units. A computer terminal collects PLC data from the site, compiling relevant tables for easy production record keeping, and enabling centralized real-time monitoring on the computer terminal. Furthermore, it leverages internet technology for remote monitoring via mobile devices. Personnel not on-site can monitor the entire automatic control real-time monitoring system via computer or mobile phone. Overall, this automatic control real-time monitoring system automates the recycling of precious metals such as silver, saving manpower and costs, and improving recycling production efficiency. The recycling status of the entire automatic control real-time monitoring system can be queried and monitored in real-time on both computer and mobile terminals. Furthermore, the recycled data is automatically generated into tables and archived using configuration technology for easy retrieval.

[0010] Furthermore, the PLC unit and the touch screen are connected via communication line I, and the PLC unit and the computer remote monitoring terminal are connected via communication line II.

[0011] Furthermore, when there are multiple electroplating machines and multiple corresponding PLC units, an N:N communication network is used to centrally control all PLC units from the PLC unit master station to the PLC unit slave station communication technology; all PLC units use configuration control technology to control all collection and recycling units to achieve bidirectional network communication control, and use computer remote technology to achieve real-time monitoring by smartphone monitoring terminals.

This automated control real-time monitoring system implements PLC + touchscreen automated control at the electroplating site. The PLC unit is the well-known Mitsubishi FX series from Japan, and the touchscreen is the Kunlun Tongtai TPC1061Ti, also well-known to those skilled in the art. It can achieve real-time monitoring of the silver recovery and operating status of a single electroplating machine, or it can monitor multiple electroplating machines. Specifically, one PLC unit can control one collection and recovery unit on one electroplating machine, or multiple collection and recovery units can be set and arranged according to actual needs. The touchscreen allows for setting daily recovery time, runtime, manual / automatic operation, dynamic display of operation, and protection function settings. A computer remote monitoring terminal is used to link with the PLC unit, collecting data from the entire automated control real-time monitoring system on-site. Centralized monitoring is achieved on the computer remote monitoring terminal, and the data is then compiled into tables for easy archiving and retrieval through a data archiving unit. Furthermore, internet communication technology can be used to achieve remote monitoring via mobile phone monitoring terminals, allowing responsible personnel to monitor in real-time even when not on-site. In this way, it is possible to connect and control multiple collection and recycling units through PLC unit connection technology, and at the same time realize communication between the PLC unit and the computer remote monitoring terminal to complete remote monitoring; it is also possible to realize remote control between the mobile phone monitoring terminal and the computer remote monitoring terminal through Internet monitoring technology, so as to realize real-time monitoring of the silver recycling production line of the roll electroplating line by mobile phone.

Each collection and recycling unit is connected to the main recycling tank I. The main recycling tank I and main recycling tank II are also independently controlled by the PLC unit. The motor pump between the main recycling tanks is used to transport the treated wastewater from the main recycling tank I to the main recycling tank II, so as to facilitate the recycling and reuse of the treated wastewater. The low liquid level detection sensor and high liquid level detection sensor of the main recycling tanks I and II are used to detect the low and high liquid levels of the main recycling tanks I and II, respectively, to prevent the water level of the main recycling tanks I and II from being too low or too high.
