Integrated device for ptc heater withstand voltage test and cooling strip bonding

Abstract

An integral device for PTC heater voltage resistance testing and heat sink strip bonding belongs to the technical field of electronic and electric components testing device. The integral device comprises a test board, a board panel is arranged on the test board, and a barrier strip is fixed on the upper part of the board panel; an electric control box is arranged on the front side of the test board; an electrode guide vane socket is arranged on the test board and is connected with the electric control box in an electric control mode; an electrode guide vane socket driving mechanism is arranged on the test board and is connected with the electrode guide vane socket; a warning mechanism is arranged on the rear side of the test board and is connected with the electric control box in en electric mode; a heat sink strip cementation pressure applying mechanism is arranged on the test board and is connected with the electric control box in an electric control mode. According to the device, the testing efficiency is high, the operation intensity of testing personnel is low, the security is reliable, and reliable combination effect of heat sink strips and heat conduction pipes of heating cores is guaranteed; human input can be reduced, and detecting speed requirement in industrialization enlarged production of PTC heaters is satisfied.

Description

technical field [0001] The invention belongs to the technical field of testing devices for electronic and electrical components, and in particular relates to a device integrating a PTC heater withstanding voltage test and heat dissipation strips. Background technique [0002] Because PTC heaters (also known as PTC heaters, the same below) have the characteristics of fast start-up speed, good temperature control, high working reliability, excellent energy efficiency ratio and long service life, they are used to manufacture various electric heating appliances such as Key components of air conditioners, heaters, clothes dryers, dishwashers, water heaters, food processors, heated floor cleaners, etc., and even as current limiters, overcurrent protectors, overload protectors, degaussing controllers , The core component of the control and protection device such as the start controller. Among them, the application of PTC heaters on air conditioners as household appliances is relat...

AI Technical Summary

Problems solved by technology

[0004] In the existing technology, workers test the PTC heaters to be tested one by one. This test method has at least the following technical problems: first, the labor intensity of the workers is high; second, the test efficiency is low; third, the safety is poor ; Fourth, a lot of manpower is invested, resulting in a waste of labor resources

[0008] In the process of manufacturing PTC heaters, the aforementioned heat dissipation strips are usually glued to the heat pipe of the heat pipe by hand through adhesive (adhesive is pre-coated on the outer wall of the heat pipe of the heat core), and this operation method has labor intensity. Large size, low bonding efficiency and poor bonding effect. In the actual use process, there is a situation that the heat dissipation strip and the heat pipe of the heating core are separated, which affects the performance of the PTC heater and causes waste of electric energy.
