Problems solved by technology

[0004] However, the use of the above constant temperature aging device, due to the use of light bulbs to directly heat the inside of the aging rack, on the one hand, it will cause the situation that the items to be tested close to the light bulb will be burnt; The environment of each item to be tested in the rack will be different. The temperature control probe only detects the temperature of a certain point, and then the judgment of heating or cooling is not accurate, so the test result will be inaccurate.

Abstract

The invention discloses a constant temperature aging device, comprising an aging frame, a temperature controlled probe, a relay, an electromagnetic valve, a cylinder and a PTC (Positive Temperature Coefficient) heater, wherein one side of the aging frame is provided with a door; one face of the aging frame is provided with an opening; the opening is convexly provided with sliding slots at the two sides on the outer wall of the aging frame; plugboards are inserted into the sliding slots; the temperature controlled probe is arranged in the aging frame to detect the environmental temperature in the aging frame; the relay is connected with the temperature controlled probe so as to obtain the environmental temperature detected by the temperature controlled probe and compare the environmental temperature with a preset temperature; the electromagnetic valve is connected with the relay and controlled by the relay; the cylinder is connected with the electromagnetic valve and is controlled by the electromagnetic valve; the PTC heater is arranged at a place where the aging frame is closed to the bottom and connected with the relay; and when the environmental temperature in the aging frame is less than the preset temperature, the PTC heater is started to heat so as to provide an accurate testing environment. The articles to be tested are uniformly heated to avoid baking.

Description

【Technical field】 [0001] The invention relates to a constant temperature aging device, in particular to a constant temperature aging device in which an object to be tested is evenly heated. 【Background technique】 [0002] With the development and progress of science and technology, electronic products are more and more widely used in homes and offices. And some electronic products (such as laptops) need to undergo aging tests before leaving the factory. The purpose of the aging test is to expose the defects of the products before leaving the factory, such as the reliability of the solder joint connection, the design, material and process of the product, etc. Various defects, in order to improve the stability of the product, find some defects and make up for them before leaving the factory, and reduce the repair rate of the product. [0003] The current constant temperature aging device includes a constant aging rack. The item to be tested is placed in the aging rack, and a ...
