Detailed ways

The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples are only used to explain the present invention, but not to limit the scope of the present invention.

As shown in Figure 1, Figure 2, Figure 3, Figure 4, the data server is mainly used to record the number of electronic components in inventory and communicate with the main control system to read the inventory of electronic components. If the inventory of components is insufficient, the server An early warning message will be delivered to the administrator PC. In addition, the remote PC can query the inventory information of the electronic component library through the public network, and can directly place an order, and the server can print the order information. The administrator PC can communicate with the remote PC to realize online technical exchange and resource sharing.

The main control system is mainly to record the outgoing and incoming of electronic components, calculate the inventory of electronic components, and send the inventory information to the data server. Before the electronic components are put into the warehouse, a barcode label is established, and the label contains the name, quantity, and serial number of the label. When the device is put into the library, scan the barcode label to record the information into the library information library. When the device is out of the library, scan the out-of-stock barcode label into the out-of-stock information library. This realizes the automatic increase and decrease of electronic components. The principle of barcode scanning is that the scanner uses optoelectronic devices to convert optical signals into electrical signals. Since the electrical signal is very weak, the electrical signal should be amplified, and the analog electrical signal will be converted into a digital signal through a shaping circuit. The microcontroller collects the signal.

Electronic components are widely used in electronic equipment. Due to the rapid replacement of electronic equipment, a large number of electronic components have caused great waste, so the recycling of old circuit boards is of great significance and considerable profit. The electronic components on the circuit board have inconsistent performance, a wide variety, and the composition of materials is also very different. Usually there are transformers, diodes, integrated circuit modules, resistors, capacitors, MOS tubes and other electronic components. Therefore, when dealing with the old circuit board, it is necessary to disassemble the electronic components of the old circuit board and deal with it separately. Electronic components are connected to the circuit board by soldering. Therefore, to recycle electronic components, the first step is to separate the components and the PCB board. Then recycle valuable electronic components, formulate a targeted recycling plan for valuable components, and effectively control the harmless treatment of harmful and toxic substances, which will minimize recycling costs and obtain considerable profits. .

The method of tin solution for electronic components is laser tin solution. Initially, PCBs (printed circuit boards) were manually disassembled from the collected electronics. At this stage, flexible manual operations are used, allowing equipment disassembly from various sources. After this manual disassembly process, the PCBs are fastened to a frame with a special holding device into the disassembly unit. Reusable parts and toxic components on circuit boards are identified by means of an identification system with image processing - the "vision system". This is achieved by comparing part shapes and labels against a database containing manufacturer information and reuse market information. In addition to this, the system must determine the location, size and regional center of the component under consideration and provide this data as input for the next station. To obtain the data required for selective disassembly, a high-quality image inspection system is required. To locate and identify reusable components on PCBs, vision systems must be able to achieve an accuracy of 0.1mm and recognize characters on parts. Thereby, parts deemed valuable or potentially dangerous are laser peeled off and removed using special robotic grippers in the next step. The combination of special laser tin removal technology and special robotic arms allows us to remove a wide variety of electronic components from processed PCBs. Finally, we obtained suitable reusable electronic components and environmentally friendly PCBs components, and cooperated with companies responsible for recycling to recycle harmful components and realize resource utilization.

The component detection circuit is composed of a controller circuit, a liquid crystal display circuit, and a matrix button circuit. Since the recovered valuable chips may be damaged, the chips should be inspected, and then the bad components should be specially repaired. (The chip test circuit is to detect whether the digital integrated chip is damaged. By comparing the output logic level of the tested chip with the results in the chip truth table library, it is determined whether the integrated chip is damaged. The fixed logic level is added to the input pin of the digital integrated chip under test, and then the state of the output pin level of the tested chip is detected, and finally the test conclusion of the data analysis and processing is displayed on the LCD screen. At the same time, for convenience, according to the matrix The specific key value of the button corresponds to the corresponding chip model, and then the single-chip microcomputer calls the test of the truth table of the tested chip according to the value of the button. ) [Wang Wei. Digital integrated chip detector based on single chip microcomputer [J]. Science and Technology Innovation, 2016(23):109-109] The principle of chip measurement. At the same time, the probability of damage to capacitors, resistors, etc. is relatively low. Therefore, in order to mobilize the enthusiasm of the students, students will also be involved in the process of testing the quality of the components, so that the students can understand the general process of electronic components, which will help to truly improve the utilization efficiency of electronic components. In addition, freshmen like freshmen can recognize electronic components in advance, as well as the properties of electronic components, which will help students to learn in the future.
