Problems solved by technology

[0003] At present, the production of PTC-type heaters is carried out in large quantities. In the production process of existing PTC-type heaters, when arranging PTC heat-sensitive ceramic sheets, it is necessary to manually arrange them one by one. On the one hand, it is difficult to control the interval of manual arrangement. On the other hand, it is difficult to guarantee whether the PTC heat-sensitive ceramic sheets can be arranged vertically, and the quality of the sheet arrangement is low. At the same time, if the manual operation is careless, it is easy to cause the PTC heat-sensitive ceramic sheets to dump, and it is necessary to re-arrange the sheets, resulting in low production efficiency

Embodiment 1

[0037] A method for processing a PTC type heater, the specific steps are:

[0038]1) Preparation of PTC heat-sensitive ceramic tablets: first put the raw materials into a grinding mill, grind and stir for 8 hours; then put the pulverized and stirred mixture into an airflow granulator, and place the granulated particles In the molding machine, it is pressed into a sheet; then the PTC heat-sensitive ceramic sheet pressed into a sheet is sintered in a kiln, and after the sintering is completed, it is cooled by high-pressure air blowing with pure nitrogen; Grinding and chamfering with a chamfering machine; finally, cleaning and drying the PTC heat-sensitive ceramic heating element for later use;

[0039] Wherein, the composition of raw material and the parts by weight of each composition are respectively: BaCO 3 60 parts, SrCO 3 11 copies, Y 2 o 3 0.5 parts, SiO 2 0.3 parts, TiO 2 40 parts BaTiO 3 25 copies;

[0040] High-pressure air blow cooling is divided into 5 bl...

Abstract

The invention provides a processing process for a PTC type heater. The processing process comprises the following concrete steps: preparing PTC thermal sensitive ceramic chips, preparing a bonding glue, pre-treating aluminum tubes and electrode slices, splicing electrode strips, arranging PTC thermal sensitive ceramic chips, moulding and pressing, and splicing wave-shaped radiating strips. Compared with the prior art, the processing process has the following beneficial effects: with the adoption of a slidable strip clamping bar of a stable chip arranging device, the spaces of the PTC thermal sensitive ceramic chips in the chip arrangement can be guaranteed to be the same and the artificial visual inspection is not required, so the chip arranging quality is improved; moreover, each of the PTC thermal sensitive ceramic chips can be guaranteed to be vertically arranged, and the phenomenon that the arranged PTC thermal sensitive ceramic chips are toppled over does not occur; and thus, the chip arranging quality is further guaranteed, and the chip arranging efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of PTC heater processing, in particular to a PTC heater processing method. Background technique [0002] PTC plus heating element has the incomparable advantages of traditional heating elements such as constant temperature heating, no open flame, high heat conversion rate, safety and energy saving, little influence on power supply voltage, and long natural life. It is more and more popular in the application of electric heating appliances. of favor. [0003] At present, the production of PTC-type heaters is carried out in large quantities. In the production process of existing PTC-type heaters, when arranging PTC heat-sensitive ceramic sheets, it is necessary to manually arrange them one by one. On the one hand, it is difficult to control the interval of manual arrangement. , On the other hand, it is difficult to guarantee whether the PTC heat-sensitive ceramic sheets can be arranged vertically, and the qua...
