Problems solved by technology

This detection method requires the cooperation of three people to operate, and, at high temperature, it is easy to cause safety accidents such as tin splashing and scalding.
In addition, the error of the solder resistance test of the pins is relatively large, the test results are very inaccurate, and the product is prone to hidden dangers in the reliability of display characters, resulting in a high rate of customer failures on the line and an increase in the number of returned products
The reduction of product quality has also caused huge economic losses to the enterprise, thereby increasing production costs virtually

Abstract

The invention relates to a device for testing the soldering resistance of a pin of a liquid crystal display. The device comprises a product fixing clamp table, a heat insulation baffle, a heating device, a tin melting assembly, a tension testing assembly and a base. According to the invention, a single product can be clamped, welding resistance testing can be carried out on pins at different positions of the product, and the working efficiency can be obviously improved. The product is stably clamped without extra force application, and hand fatigue is effectively prevented. The integrated rail integrated design is adopted, so that the distance between the hand of a tester and a high-temperature tin melting assembly solution is adjusted, and scalding accidents are avoided. When the device is used for testing, the testing time is completely the same, and therefore the technical problem that in the prior art, due to the influence of manual operation, the pin welding time is different, and consequently the detection result is inaccurate is effectively solved.

Description

technical field [0001] The invention relates to the field of LCD liquid crystal displays, in particular to a device for testing the solder resistance of liquid crystal display pins. Background technique [0002] There are more and more connection methods for liquid crystal display devices, including zebra strips, flexible circuit boards, metal pin connections, etc. Among them, pin connection is the most important type in the LCD manufacturing industry, and the solder resistance of pin connections Performance and reliability are the key factors to determine whether the entire liquid crystal display device can work normally. This is because when the reliability of the solder resistance of the pins and UV glue does not meet the requirements, it will directly affect the welding quality of the LCD screen: for example, the pin bayonet is skewed and loose, and the UV glue on the surface is not firmly fixed, which will cause the metal bayonet and glass The ITO electrodes on the ste...
