[0002] The installation environment for smart energy meters varies greatly across my country, especially in the southern coastal areas, where high temperatures, humidity, and salt content significantly impact the circuit boards and components within smart energy meters. Furthermore, summer is a frequent season for floods, significantly increasing the damage rate of energy meters.

[0003] Although the one-piece molding structure has good sealing performance and solves the sealing problem between the copper terminal and the plastic shell, defective and scrapped products in production are difficult to separate because the copper terminal is completely wrapped by the plastic shell. They can only be disassembled by cutting, which has a high risk factor. Moreover, the copper terminal and plastic cannot be recycled after disassembly, resulting in high loss.

[0004] Therefore, this patent designs a single-phase IP68 high protection electric energy meter terminal removal device, which can remove the copper terminal by heating. There is no plastic adhering to the surface of the removed copper terminal, so the removed copper terminal can be reused, reducing resource waste, loss and cost. Moreover, when the copper terminal is removed, the plastic will not be burned, and there will be no burning or blackening. The plastic particles after the old shell plastic is crushed after removal can also be recycled and reused. Utility Model Content

DETAILED DESCRIPTION

[0018] Reference Figures 1 to 3 The embodiments of the present invention are further described.

[0019] A single-phase IP68 high-protection electric energy meter terminal removal device includes a frame 1, a cylinder regulating valve 2 and a temperature and pressure controller 3. The frame 1 is provided with a stamping cylinder 4 and a terminal removal punch 5. The frame 1 includes a workbench 6 for placing a plastic shell 01. The stamping cylinder 4 is installed on the frame 1, and the output end of the stamping cylinder 4 is connected to the terminal removal punch 5. A heating element 7 and a temperature sensor 8, both of which are electrically connected to the temperature and pressure controller 3, are installed in the terminal removal punch 5. The terminal removal punch 5 includes a push rod 501 that cooperates with the heating element 7 and the temperature sensor 8. The push rod 501 corresponds to the copper terminal on the plastic shell 01. An air inlet pipe 9 and an air outlet pipe 10 are connected to the temperature and pressure controller 3. The cylinder regulating valve 2 is installed on the air inlet pipe 9, and the air inlet pipe 9 is connected to the air inlet end of the stamping cylinder 4, and the air outlet pipe 10 is connected to the air outlet end of the stamping cylinder 4.

[0020] Working principle: Place the plastic shell 01 from which the copper terminal is to be removed on the workbench, and make the copper terminal of the plastic shell 01 correspond to the terminal removal punch 5. The temperature and pressure controller 3 controls the heating element 7 to heat the terminal removal punch 5, thereby heating the ejector pin 501 on the terminal removal punch 5. The temperature sensor 8 feeds back the temperature of the terminal removal punch 5 to the temperature and pressure controller 3, so that the temperature of the ejector pin 501 on the terminal removal punch 5 is always maintained at the temperature value set by the temperature and pressure controller 3. When the temperature of the ejector pin 501 on the terminal removal punch 5 reaches the temperature set by the temperature and pressure controller 3, the temperature of the ejector pin 501 on the terminal removal punch 5 is kept at the temperature value set by the temperature and pressure controller 3. After the temperature value is reached, the stamping cylinder 4 works to press the terminal removal punch 5 and the ejector pin 501 thereon downward, so that the ejector pin 501 contacts the copper terminal of the plastic shell 01 and applies pressure to the copper terminal for a certain period of time. During this process, the heated ejector pin 501 heats the copper terminal, causing the copper terminal to heat up and soften the plastic around the copper terminal, so that the heated ejector pin 501 can press the copper terminal out of the plastic shell 01 during the downward pressing process, thereby realizing the removal of the copper terminal from the plastic shell 01. The return time and return speed of the stamping cylinder 4 are controlled by setting parameters on the temperature and pressure controller 3.

[0021] The cylinder pressure regulating valve is used to control the air pressure in the air inlet pipe 9 connected to the air inlet end of the stamping cylinder 4, thereby controlling the pressure and speed of the stamping cylinder 4 pressing down, and then controlling the pressure and speed of the terminal removal punch 5 and its upper push rod 501 pressing down. The air outlet end of the stamping cylinder 4 is connected to the temperature and pressure controller 3. Through the parameter setting of the temperature and pressure controller 3, the downward pressing time of the terminal removal punch 5 at the output end of the stamping cylinder 4 is controlled, thereby controlling the punching time of the push rod 501 on the copper terminal on the plastic shell 01, so that the push rod 501 on the terminal removal punch 5 completely presses out the copper terminal on the plastic shell 01, thereby improving the removal effect, and finally realizing the removal of the copper terminal from the plastic shell 01 by heating. There is no plastic adhered to the surface of the removed copper terminal, so that the removed copper terminal can be reused, reducing resource waste, loss and cost. When the copper terminal is removed, the plastic around the copper terminal is melted so that the plastic will not be burned, and there is no burning or blackening phenomenon. The plastic particles after the old shell plastic is crushed after removal can also be recycled.

[0022] The terminal removal punch 5 also includes a heating die base 502 connected to the ejector pin 501 and a fixing rod 503 connected to the heating die base 502. The fixing rod 503 is connected to the output end of the stamping cylinder 4. The heating die base 502 includes a heating chamber 001. The heating element 7 is installed in the heating chamber 001. One end of the ejector pin 501 extends into the heating chamber 001 and is connected to the heating element 7, which is convenient for the installation of the heating element 7 and the temperature sensor 8. At the same time, it is convenient for the heating element 7 to directly heat the ejector pin 501 in the heating chamber 001. The setting of the heating chamber 001 reduces the heat loss of the heating element 7 and accelerates the heating speed of the ejector pin 501. The surface of the ejector pin 501 is coated with a polytetrafluoroethylene coating. When the ejector pin 501 presses the copper terminal on the plastic shell 01, the melted plastic around the copper terminal will not adhere to the ejector pin 501.

[0023] A limiting die base 11 corresponding to the terminal removal punch 5 is installed on the workbench 6. A die cavity 002 for placing the plastic shell 01 is opened on the limiting die base 11. The plastic shell 01 of the copper terminal to be removed is placed in the die cavity 002 so that the die cavity 002 can limit the plastic shell 01 and prevent the plastic shell 01 from shaking when the push rod 501 on the terminal removal punch 5 punches the copper terminal, affecting the removal of the copper terminal.

[0024] A start button 12 for controlling the start of the stamping cylinder 4 and an emergency stop button 13 for controlling the stop of the stamping cylinder 4 are installed on the workbench 6. The start button 12 is used to control the stamping cylinder 4 to start working, so that the terminal removal punch 5 connected to the output end of the stamping cylinder 4 is pressed down. After the terminal removal punch 5 presses out the copper terminal on the plastic shell 01, the stamping cylinder 4 is stopped by starting the emergency stop button 13.

[0025] The output end of the punching cylinder 4 is equipped with a fixing plate 14 connected to the fixing rod 503, and the frame 1 is movably connected with a guide rod 15 connected to the fixing plate 14, so that the punching cylinder 4 is more stable when pressing down and returning.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
