Description

Curing molding equipment for PTC heating device

Technical Field

The invention belongs to the field of electronic machinery, and particularly relates to curing molding equipment for a PTC heating device.

Background

The PTC heating device has the advantages of constant temperature heating, no open fire, high heat conversion rate, little influence of power supply voltage and the like, and is widely used in various electric appliance products. Chinese patent 200920230829.5 discloses a PTC electric heater, which comprises a heat conducting aluminum tube, a heat dissipating strip and a heating element penetrating into the heat conducting aluminum tube, wherein the heating element is composed of a PTC heating element clamped between electrode plates and coated by a temperature-resistant insulating film, and temperature-resistant and flame-retardant organic silica gel is used between the PTC heating element and the electrode plates in the heating element and between the heating element and the heat dissipating strip to bond the heating element and the electrode plates and the heating element and the heat dissipating strip together and form a heating device which is tightly combined with each other after high-temperature curing.

In the prior art, a plurality of groups of PTC heating devices are generally placed on a bedplate by hand and fixed in a tool with a movable frame, a corrugated heating surface of a heater is knocked flat, the frame is clamped by using screws or nuts to position the heater, and then the heater is placed in an oven with a set temperature for curing.

In recent years, the constant temperature heating performance of the PTC heating element is utilized, a plurality of groups of PTC heating devices are placed on a bedplate, after the corrugated heating surface of the heater is flattened, the leading-out end part and the tail end part of the heating device are flattened by hands and tools, then the heating device is manually clamped by a tool, and then a power supply is connected to an electrode plate of the heater to heat the PTC heater and utilize the heat generated by the constant temperature of the PTC heater to solidify the adhesive silica gel.

The process or the technology has low efficiency, large power consumption in the curing process and poor product consistency, can not avoid the occurrence of unqualified products caused by human misoperation, has high failure rate, and needs to be electrified or subjected to high-voltage tests after curing.

Disclosure of Invention

The purpose of the invention is as follows: the invention aims to provide curing and molding equipment for a PTC heating device, aiming at overcoming the defects of the prior art.
