EMBODIMENT

[0029] Referring to Figures 1-4 As shown in the drawing, a polytetrafluoroethylene cushion packing plate comprises a packing plate body 1, the packing plate body 1 is provided with a protruding part 101, the protruding part 101 is provided with a chip slot 102, an RFID chip 2 is embedded in the chip slot 102 by high-temperature glue, each RFID chip 2 is written with a unique number, and the identification and management of the packing plate can be realized. Wherein, the packing plate body 1 is composed of a semi-cured sheet 11 of polytetrafluoroethylene material, glass cloth 12 and an aluminum sheet 13 coated with silicon oil on one side, the upper and lower end faces of the semi-cured sheet 11 are provided with the glass cloth 12, the outer sides of the glass cloth 12 are provided with the aluminum sheet 13, and the side coated with silicon oil of the aluminum sheet 13 faces the glass cloth 12.

[0030] The aluminum sheet 13 in this embodiment is 140 microns thick, single-sided coated with silicone oil. Compared with the original copper foil, its thickness is significantly larger and the material cost is reduced. This thicker aluminum sheet brings many advantages to the polytetrafluoroethylene cushion pad plate. First, it increases the overall strength and stability of the pad. During use, it can better withstand various pressures and impacts and is not easy to deform and damage. Second, the larger thickness improves durability and extends the service life of the pad. At the same time, after the aluminum sheet is coated with silicone oil, the silicone oil can isolate the external environment to some extent and enhance the overall corrosion resistance of the gasket.

[0031] In this embodiment, the glass cloth 12 is a one-time desizing glass cloth without glue. This glass cloth is treated with special desizing process, and the design without glue makes it have unique advantages. On the one hand, not coating glue reduces possible chemical pollution and is more environmentally friendly; on the other hand, it improves the air permeability of the glass cloth, so that it can better play its performance when used in combination with other materials.

[0032] Two identical glass cloths are arranged between the prepreg 11 and the aluminum sheet 13. Among them, the prepreg 11 uses 45 pieces of 7.4 mil thick polytetrafluoroethylene prepreg, namely 7628 polytetrafluoroethylene prepreg. This prepreg has excellent performance, such as good high temperature resistance, corrosion resistance and insulation, etc.

[0033] During preparation, the prepreg 11, glass cloth 12 and aluminum sheet 13 are arranged in order, and then placed in a 400°C high temperature press for 5 hours. High temperature pressing can make the materials in each layer tightly combined together to form a firm pad body 1. The process needs to strictly control the temperature and time to ensure the quality and performance of the pad. After such preparation process, the obtained polytetrafluoroethylene cushion pad has good cushioning performance, durability and stability, and can meet various application requirements.

[0034] In combination Figure 3 , Figure 4As shown, a foolproof system for polytetrafluoroethylene cushion pad plate is composed of the above-mentioned polytetrafluoroethylene cushion pad plate, a code reader 3 and an MES system 4. The pad plate body 1 is provided with a numbered RFID chip 2, which has uniqueness and provides convenience for the identification and management of the pad plate. The code reader 3 is installed on the CCL production line at the path through which the pad plate passes. When the pad plate passes through the signal receiving area of the code reader 3, the code reader 3 can accurately read the data on the RFID chip 2 and transmit these data to the MES system 4. The above-mentioned MES system 4 is installed on a computer. The MES system 4 can record the number of times according to the preset pad plate number and upper limit of service life, so as to accurately grasp the use of each pad plate. Through accurate recording of the number of times of use of the pad plate, the problem of missed or wrong recording that is prone to occur when recording the number of times manually can be effectively avoided, and the accuracy and efficiency of production management are greatly improved. At the same time, when the number of times of use of the pad plate approaches the upper limit of service life, the MES system can also give a warning of the number of times, reminding the relevant personnel to replace the pad plate in time, so as to ensure the smooth progress of the production process and the stability of the product quality. The application of this foolproof system provides a scientific and efficient solution for the use and management of polytetrafluoroethylene cushion pad plate.

[0035] In the process of interaction between the MES system 4 and the code reader 3 device, the WatchService event-driven method is adopted. This method is an extremely efficient, scalable and real-time file system monitoring solution. It can listen to the data changes of the industrial computer, and when there are data changes, it can respond quickly through the active pushing mechanism at the operating system level. This method greatly reduces the consumption of CPU resources and delay, ensuring that the system will not be stuck or have performance degradation during operation due to a large amount of data processing. In addition, the new WatchService can be configured with different processing strategies to be flexibly adjusted according to actual needs. This greatly improves the granularity and fineness of event processing, so that the system can respond more accurately to various data change situations. Whether it is fast data acquisition or accurate storage, it can be effectively guaranteed. Through this method, in the use process of the polytetrafluoroethylene cushion pad plate, the data interaction between the MES system and the code reader can be efficient and accurate, providing reliable data support for production management and improving the intelligent level and management efficiency of the entire production process.

[0036] The utility model discloses to the traditional polytetrafluoroethylene cushion pad has carried out the innovation improvement. Adopt aluminium sheet instead of traditional electrolytic copper foil, and aluminium sheet is relatively lower in cost, thereby effectively reduce material cost. Meanwhile, through setting up the RFID chip of taking number on the cushion plate body, and cooperate the code reader and MES system, form the informatization foolproof system. When the cushion plate passes through the signal receiving area of code reader, the code reader reads the data on the RFID chip and transmits to the MES system, and this system carries out analysis and record, thereby accurately forms the use frequency record of polytetrafluoroethylene cushion pad. In the MES system, can realize the monitoring of polytetrafluoroethylene cushion pad life, when use frequency is close to the upper limit of life, still can send early warning function, remind relevant personnel and replace the cushion plate in time, ensure the smooth progress of production process and the stability of product quality, provide efficient, reliable solution for the use management of polytetrafluoroethylene cushion pad.
