Description

Method for manufacturing ceramic heater in electronic cigarette atomizer

Technical Field

A method for manufacturing a ceramic heater in an electronic cigarette atomizer, in particular to a method for manufacturing a ceramic heater specially used in an electronic cigarette atomizer.

Background

At present, in the manufacture of a ceramic atomizing heater in an electronic cigarette, a ceramic body is sintered on a heating coil with an electrified heating wire element A to manufacture a ceramic heater with ceramic porosity, and the ceramic heater uses the high temperature resistance characteristic of ceramic and the surface micropores have hygroscopicity so as to adsorb smoke oil. Referring to fig. 1, a method for manufacturing a ceramic atomizing heater in an electronic cigarette includes the steps of, before the process is performed, taking out a single heating wire component a from a plurality of stacked heating wire components a, vertically inserting the leads of the heating wire component a into the die holes B1 of the die B, pressing down to expose the heating coil portion of the heating wire component a, covering the die cavity positioning device with a layer of gate plate, pouring ceramic C, cooling and shaping the cavity, separating the gate plate, and ejecting the finished ceramic heater out of the die cavity and leaving the die.

However, there are several disadvantages to the existing production methods. Firstly, in the conventional production method, before the process is started, the heater elements a must be taken out one by one from the stacked raw materials, and since the pins of the heater elements a are stacked and overlapped with each other, the pins of the heater elements a are easily entangled and overlapped with each other, so that not only is the selection process time and power consuming, but also the pins are easily bent and deformed during the pulling process, thereby affecting the process yield of the heater elements a.

Furthermore, after the heating wire components a are individually and singly taken out manually, because the pins are easy to deform, the pins of the heating wire components a can be inserted into the mold B after being manually folded and restored, but the pins of the heating wire components a on the mold B are extremely small and are not easy to align, so the pins of each heating wire component a need to be manually inserted after being rearranged, and the height of the heating wire components a after being manually inserted is not always equal to the height, so that the heating wire components a need to be pressed, leveled and the production efficiency is influenced by increasing the labor hour.

And finally, ejecting the finished ceramic heater out of the die cavity, and if the ceramic C is not cured enough, easily generating fracture and deformation due to ejection force, thereby influencing the overall quality of the finished product.

Therefore, the conventional production method has the problems of insufficient yield, time-consuming production efficiency and low quality, and a new production method is needed to increase the yield of the finished product, increase the production efficiency and quality and reduce the labor cost.
