Description

Technical Field

[0001] The utility model relates to the field of thermistor processing, in particular to a fixed mold for making thermistor electrodes. Background Art

[0002] The thermistor is mainly in the shape of a rectangular parallelepiped, which generally includes a thermistor ceramic body and electrode terminals at both ends. The thermistor ceramic body is obtained by pressing and sintering, and the electrodes are coated on both sides of the ceramic body by tools. The electrode structure of the thermistor is to form a surface electrode by coating a conductive slurry. Under certain conditions, there are strict requirements on the position and size of the electrode coating. Therefore, a fixed mold corresponding to the electrode coating position is also required. The existing electrode coating method is mainly manual coating. The electrode coating area is determined by measurement, and the thermistor is fixed by grasping with one hand, and the electrode is coated with a brush with the other hand. This method can achieve electrode coating on both sides of the thermistor. However, this method also brings some problems. First, due to the manual measurement of the coating area, it has a great impact on production efficiency; secondly, the grasping method may produce certain errors in the electrode coating process, which will increase the defective rate of the product.

The upper part of the thermistor is flush with the top of the base, and the rectangular cover plate is covered. The screw passes through the rectangular cover plate to ensure that the bottom of the rectangular cover plate is closely fitted with the top of the base, and then the butterfly nut and the screw are used to fasten the rectangular cover plate and the base. Finally, put the rectangular sleeve between the base and the rectangular cover, use a small brush to coat the electrode on the exposed part of the thermistor, remove the sleeve after one coating, and coat the remaining exposed part of the thermistor again; when demolding after coating, first loosen and remove the butterfly nut, then remove the rectangular cover, and finally remove the thermistor; the fixed mold can fix multiple thermistors at a time, without manual measurement, and is convenient for determining the coating area; it can improve the electrode coating efficiency, thereby achieving the effect of improving production efficiency and reducing product defective rate.
