Problems solved by technology

However, the temperature control method of the existing reflow soldering machine has a large difference between the actual temperature and the ideal temperature curve, and there are problems such as complicated programming and high requirements for operators, so it is difficult to achieve a higher quality level of welded parts
[0003] It can be seen that the above-mentioned existing reflow soldering machine temperature control method obviously still has inconvenience and defects in use, and needs to be further improved urgently.

Abstract

The invention discloses a temperature control method for a reflow welding machine. The temperature control method comprises the following steps of: a, importing an ideal temperature curve graph of soldering paste and editing a time-temperature control curve according to an ideal temperature curve; b, controlling a heater to heat according to the time-temperature control curve obtained by editing in the step a; c, generating an actual temperature curve according to detected real-time temperature of a welding part in a welding cavity; and d, newly editing the time-temperature control curve according to the actual temperature curve and the ideal temperature curve, repeating in such a manner and determining a final time-temperature control curve after the actual temperature curve is achieved. According to the temperature control method, the temperature in the welding cavity can be accurately controlled, and the operation is easy.

Description

technical field [0001] The invention relates to the technical field of reflow soldering machines, in particular to a method for controlling the temperature of a reflow soldering machine. Background technique [0002] Due to the continuous miniaturization of PCB boards of electronic products, chip components have appeared, and the traditional welding method can no longer meet the needs. With the development of surface mount technology, the reflow soldering machine as a part of surface mount technology has also been developed accordingly, and its application is becoming more and more extensive, and it has been applied in almost all electronic product fields. There is a heater in the welding cavity formed in the welding box of the reflow soldering machine, so that the components on the circuit board in the welding cavity can be welded together with the circuit board through the melted solder paste. Since different solder pastes have different characteristics, when soldering, i...
