A multi-stage controllable heating platform device and heating control method

Abstract

The invention belongs to the field of heating control, and specifically discloses a multi-stage controllable heating platform device and a heating control method. The device comprises a heating platform control module and a heating platform module. The heating platform control module is used for realizing temperature control of the heating platform module. The heating platform module comprises a heating platform and a fixed supporting heat dissipation box. The heating platform is used to realize heating and positioning a to-be-heated material, and the heating platform is provided with a temperature detector and a heating rod. The temperature detector is used for transmitting temperature of the heating platform to the heating platform control module. The heating platform control module changes temperature of the heating platform by controlling temperature rise and fall of the heating rod. The method realizes adjustment of the heating platform heating temperature, heating rate, and constant temperature time and other parameters through the device. The device and the method can realize continuous adjustment of heating temperature, heating rate, constant temperature time and other parameters in the range of room temperature to 500 DEG C, temperature control precision is not lower than 2 DEG C. The device has advantages of high adjustment precision, and reliable and convenient.

Description

technical field [0001] The invention belongs to the field of heating control, and more specifically relates to a multi-stage controllable heating platform device and a heating control method. Background technique [0002] In today's high-precision industrial production and experimental research, the important role of materials is becoming more and more prominent, whether it is in the process of material preparation, extraction or purification, or in the research and use of thermal properties of materials for industrial production, in which temperature parameters often change. It has an important impact on its application performance and material composition. For example, in the field of chip packaging, the dehydration and thermal cyclization of the precursor polyamic acid (PAA) in the manufacturing process of substrates (such as polyimide) has strict requirements on temperature parameter changes; secondly, in the field of electronic component manufacturing, The preheating t...
