Safe oven and control method thereof

Abstract

The invention discloses a safe oven and a control method thereof. The safe oven comprises a central control circuit, a power supply circuit, a temperature input circuit, a time input circuit, a heating control circuit, a temperature detecting circuit and a door lock control circuit. The control method comprises the following steps: setting a heating temperature through the temperature input circuit, and setting heating time through the time input circuit; sending a control signal to the door lock control circuit through the central control circuit, and locking an oven door through a door lock mechanism; sending a control signal to the heating control circuit through the central control circuit, and heating a product through the heating control circuit; detecting the real-time temperature in the oven by the temperature detecting circuit; after the heating time reaches a preset value and the real-time temperature reaches a safety value, unlocking the oven door by the door lock mechanism under the control of the door lock control circuit. Quality flaws and safety accidents are effectively prevented from occurring by the safe oven. The control method not only effectively improves product quality, but also eliminates hidden danger.

Description

technical field [0001] The invention relates to the technical field of ovens, in particular to a safety oven and a control method for the safety oven. Background technique [0002] There are many processes in the production process of circuit boards that require the use of an oven, which is used very frequently. However, in the actual baking process, the operator can open the oven at high temperature, which may cause safety hazards such as burns. When the oven door is opened, the temperature of the Yishi circuit board drops sharply, resulting in quality problems such as bending of the circuit board and insufficient stress release. In order to avoid safety accidents and ensure product quality, it is necessary to improve the oven. Contents of the invention [0003] Based on this, the purpose of the present invention is to overcome the defects of the prior art, provide a safe oven, avoid the occurrence of safety accidents, and ensure the quality of the product. [0004] Its ...
