Problems solved by technology

The disadvantages of adopting the above method are: firstly, when an error occurs in the temperature control device, the PID algorithm will stop working, causing the temperature to be in an uncontrollable state, and thus the phenomenon of product scrapping is very likely to occur; secondly, the control accuracy of the temperature cannot be guaranteed; Third, when the line is disconnected, the alarm prompt cannot be given in time

Abstract

The invention relates to a heating device in integrated circuit packaging equipment and especially relates to a heating control device used for packaging the equipment. The heating control device comprises a temperature measurement component. An output terminal of the temperature measurement component is connected with an input terminal of a temperature control module. The output terminal of the temperature control module is connected with a relay. A heating component is arranged in a power supply loop of a relay control terminal. In the heating device of the invention, the temperature control is separated from a processing scope of a system PLC controller so that the temperature control can not be interfered by factors, such as abnormity of the PLC controller. Therefore, stability and accuracy of the temperature can be guaranteed. Simultaneously, a short circuit protection function added in the invention is beneficial to protect hardware. And a broken line detection function contained in the invention can give alarm prompt in an initial failure stage so that the failure can be searched timely.

Description

technical field [0001] The invention relates to a heating device in integrated circuit packaging equipment, in particular to a heating control device for packaging equipment. Background technique [0002] Integrated circuit packaging equipment is high-precision and high-automation equipment. Its core part is the press used for packaging, and the accuracy of temperature control will directly affect the quality of packaging products. At present, the commonly used temperature control device mainly uses the temperature acquisition module to collect the current temperature, and uses the PID algorithm of its own temperature control to control the temperature. The disadvantages of adopting the above method are: firstly, when an error occurs in the temperature control device, the PID algorithm will stop working, causing the temperature to be in an uncontrollable state, and thus the phenomenon of product scrapping is very likely to occur; secondly, the control accuracy of the tempera...
