Description
Technical Field
[0001] The utility model relates to the technical field of capacitor air transport drying, in particular to a high temperature resistant heat preservation partition door and a tunnel type high temperature drying forming equipment. Background Art
[0002] During the manufacturing process, electronic components such as tantalum capacitors need to be baked to remove residual moisture and volatile substances inside. Appropriate baking temperature is important for the quality and service life of electronic components.
[0003] Taking tantalum capacitors as an example, the baking temperature of tantalum capacitors usually depends on the specific process requirements and manufacturing standards. Generally speaking, the baking temperature of tantalum capacitors needs to be carried out at a high temperature of 250°C. The high temperature of 250°C can effectively remove the residual moisture and volatile substances inside the tantalum capacitor and ensure the stability and reliability of the tantalum capacitor. In the specific baking process, the tantalum capacitor is placed in an oven or a baking oven, and the temperature is gradually increased to the set baking temperature. It is usually necessary to maintain this temperature for a period of time to ensure that the residual moisture and volatile substances inside the tantalum capacitor are fully volatilized and stabilized. Then, the temperature is gradually lowered to room temperature, and the tantalum capacitor is taken out. During the entire baking process, attention should be paid to the control of the baking temperature and baking time to avoid damage to the tantalum capacitor or performance degradation.
[0004] However, the existing automatic sliding door of the baking equipment has poor insulation effect, and the heat inside the baking equipment is easily lost through the automatic door, causing the temperature inside the baking equipment to fluctuate, resulting in the inability to maintain a constant baking temperature, affecting the baking effect. In addition, the thickness of the existing automatic sliding door is large, and it occupies more space, which undoubtedly increases the space utilization cost. Utility Model Content

For example, the second microswitch can be electrically connected to the drive component 51, the external air pump and / or the external terminal. The drive component 51 stops driving the door panel assembly 10 to open the door in the first direction according to the received door-opening signal, and the external air pump deflates the inflatable sealing ring 62 according to the received door-opening signal. The external terminal controls the remaining mechanisms of the tunnel-type high-temperature drying and forming equipment accordingly according to the received door-opening signal.
[0050] It should be noted that the in-place detection mechanism of this embodiment uses a mechanical contact detection method to perform detection. Of course, in other implementations, the in-place detection mechanism can also be implemented by methods such as photoelectric detection, image processing detection, etc., which are not limited here.

Under the premise of ensuring the structural stability and thermal insulation effect of the high temperature resistant thermal insulation partition door 100, it is suitable for manufacturing the high temperature resistant thermal insulation partition door 100 with a smaller thickness, effectively reducing the space occupancy rate.
