Technical Field

[0001] The utility model relates to the technical field of heat treatment equipment, in particular to an intelligent temperature-controlled heat treatment furnace. Background Art

[0002] Heat treatment refers to a metal thermal processing process in which the workpiece is heated, kept warm and cooled in solid state to change the chemical composition and structure of the material surface or inside to obtain the desired properties.

[0003] Heat treatment is a key step in the production process of Wi-Fi antennas, used to improve the physical and chemical properties of antenna materials, such as hardness, toughness, conductivity, and corrosion resistance, to ensure the stability and reliability of the final product. Traditional heat treatment furnaces may have deficiencies in temperature control, especially in real-time monitoring and remote control, which directly affects the quality and production efficiency of Wi-Fi antenna heat treatment. For example, the national authorized patent announcement number CN205241749U discloses a heat treatment furnace comprising a furnace body with an opening, a furnace door for closing the opening, and an electric heating assembly mounted on the inner wall of the furnace body; the heat treatment furnace also includes a drive mechanism for driving the furnace door to rise and fall, and two guide rails disposed on the bottom wall of the furnace body; the guide rails extend from the opening into the interior of the furnace body; and each guide rail is mounted with a limit member at the end away from the opening.

[0004] Since the above-mentioned heat treatment furnace still has deficiencies in temperature control, especially in real-time monitoring and remote control, this directly affects the quality and production efficiency of the WIFI antenna heat treatment.

[0005] Therefore, an intelligent temperature-controlled heat treatment furnace is proposed. Utility Model Content

The hook groove of the L-shaped rotating rod can be hooked on the outer surface of the docking rod, and the docking rod is fixedly installed at one end of the heat-insulating shell.

[0010] Preferably, the temperature control mechanism includes a thermocouple, the temperature sensing end of the thermocouple penetrates into the furnace cavity, the signal transmitting end of the thermocouple is fixedly installed in an embedded groove, and the embedded groove is opened on both sides of the heat-insulating shell.

[0011] Preferably, the thermocouple signal transmitting end of the thermocouple is connected to the signal receiving end of the temperature controller, and the temperature controller is fixedly mounted on the upper surface of the heat-insulating housing.

[0012] Preferably, a relay is integrated in the thermostat, and the relay integrated in the thermostat is electrically connected to the electric heating tube, and the electric heating tube is fixedly installed in the furnace cavity.

[0013] Preferably, the thermostat is integrated with a WiFi module, which can be connected to a local area network or the Internet, so that the user can remotely view the temperature value received by the thermostat through a mobile phone APP or computer software, and remotely modify the heating parameters through remote control of the WiFi module.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. Through the design of the furnace chamber, temperature control mechanism, L-shaped rotating rod and docking rod, when the workpiece is heat treated, the workpiece can be placed in the furnace chamber and the sleeve is closed to drive the insulation cover to block the feed port of the furnace chamber. Then the temperature control mechanism can be used to heat the workpiece in the furnace chamber. During the heating process, the temperature control mechanism will monitor the current temperature value in the furnace chamber in real time for the staff to understand, and the temperature control mechanism can also connect the temperature value to the local area network or the Internet, so that the user can remotely check whether the temperature in the furnace chamber is within the required range through a mobile phone APP or computer software, and can remotely adjust the heating amount of the furnace chamber by the temperature control mechanism, thereby realizing real-time monitoring of the temperature, ensuring the accuracy of temperature control, avoiding overheating or insufficient temperature, thereby ensuring the consistency of the heat treatment quality of the workpiece, and remote monitoring reduces the need for operators to directly contact high-temperature equipment, reducing the risk of safety accidents such as burns.

Through the design of the thermostat, WiFi module, thermocouple and electric heating tube, when the workpiece in the furnace cavity is heated, the thermostat can power the electric heating tube through the internal integrated relay, and the electric heating tube will convert electrical energy into thermal energy through resistive heating to heat the workpiece in the furnace cavity. During the heating process in the furnace cavity, the thermocouple in the furnace cavity will generate thermoelectromotive force (voltage signal) according to the heat. This signal is positive with the temperature difference, which enables the thermocouple to convert the actual temperature in the furnace cavity into an electrical signal and transmit it to the thermostat. The thermostat can control the relay to increase or decrease the current of the electric heating tube according to the heating value set by the staff to achieve precise control of the temperature in the furnace cavity. Then, the staff can connect to the WiFi module in the thermostat through a mobile phone APP or computer software.

The hook groove of the L-shaped rotating rod 103 can be hooked on the outer surface of the docking rod 104. The docking rod 104 is fixedly installed at one end of the heat insulation shell 1.

[0026] Through the design of the furnace chamber 105, the temperature control mechanism 2, the L-shaped rotating rod 103 and the docking rod 104, when the workpiece is heat-treated, the workpiece can be placed in the furnace chamber 105 and the sleeve 102 is closed to drive the insulation cover 106 to block the feed port of the furnace chamber 105, and then the temperature control mechanism 2 can be used to heat the workpiece in the furnace chamber 105.

Then the temperature controller 201 can power the electric heating tube 204 through the internal integrated relay, and the electric heating tube 204 will convert electrical energy into thermal energy through resistive heating, which is used to heat the workpiece in the furnace cavity 105. During the heating process in the furnace cavity 105, the thermocouple 203 in the furnace cavity 105 will generate a thermoelectromotive force (voltage signal) according to the heat.
