Furnace body with temperature compensating effect

Abstract

The invention discloses a furnace body with a temperature compensating effect. The furnace body comprises an upper furnace body and a lower furnace body, a channel for products to pass is arranged between the upper furnace body and the lower furnace body, an upper heating plate is arranged in a cavity of the upper furnace body, an upper temperature sensing probe assembly is arranged at the upper end of the upper furnace body, and an upper probe male plug is arranged at the electric connection wire end of the upper temperature sensing probe assembly; the upper probe male plug is connected with an upper controller female plug, and the upper controller female plug is connected with an upper temperature controller through an electric connection wire; a lower heating plate is arranged in a cavity of the lower furnace body, a lower temperature sensing probe assembly is arranged at the lower end of the lower furnace body, and a lower probe male plug is arranged at the electric connection wire end of the lower temperature sensing probe assembly; the lower probe male plug is connected with a lower controller female plug, and the lower controller female plug is connected with a lower temperature controller through an electric connection wire. According to the furnace body with the temperature compensating effect, the controllers are connected with the heating plates through the male plug and the female plug modes, the connection speed is high, additional wire connecting base is not needed, and assembly and disassembly are convenient, and time of assembly and disassembly is saved. The electric connection wire achieving an effect of bridge connection is of a hollow structure, and has the advantages that the temperature resistance is high, and the temperature sensing effect is good.

Description

technical field [0001] The invention relates to the field of SMT, in particular to a furnace body with temperature compensation function. Background technique [0002] At present, in the heating furnace in SMT technology, temperature-sensing probes are installed on the furnace body to sense the temperature of the furnace body, but the temperature-sensing probe of the furnace body needs to be connected to the controller. In the process of connecting, it is necessary to reconnect the wires. In this way, not only the original connecting wires need to be disconnected, but also it takes a long time to test the connecting wires. If the signal transmission of the connecting wires is unstable, it will affect the temperature sensor. temperature feedback. Therefore, it is necessary to design a connection line structure that is easy to disassemble and assemble. Contents of the invention [0003] The object of the present invention is to address the above-mentioned defects of the pr...
