AI Technical Summary

Problems solved by technology

For example, the operator can only rely on the feeling of the applied force, and cannot know the actual force of pressing each time, resulting in inconsistent force control during testing
When the force is too light, the test effect cannot be achieved; when the force is too heavy, it may cause damage to the LCD panel

Abstract

The invention discloses a pressure point test bar, including a main body and a straight bar. The straight bar penetrates the main body and has an exposed contact end. The pressure point test bar also comprises a spring, a magnetic force inducted switch, a magnet and a alarm unit. The spring is sleeved on the straight bar for providing the elastic force. The magnetic force inducted switch is arranged on the main body. The magnet is arranged on the straight bar. The alarm unit is arranged on the main body. When the magnet approaches the magnetic force inducted switch and the magnetic force inducted switch senses the magnetic force of the magnet, the alarm unit sends alarm. The operating staff can control the consistent force application at each time at the test pressure point by the pressure point test bar and set the pressure alarm value by regulating the magnetic force inducted switch, the magnet or the spring.

Description

【Technical field】 [0001] The present invention relates to a pressure point test stick, in particular to a pressure point test stick with warning and adjustment functions. 【Background technique】 [0002] After the production of the LCD Panel is completed, in order to ensure the quality of the LCD panel products, a pressure test step is generally included in the manufacturing process. The existing pressure test method is to use a weight of 450-500 grams Put the code on the LCD panel for a few seconds and pick it up, and then observe the situation of its anti-white or ripple recovery (disappearance) after the panel is pressed. However, this traditional testing method is manual, which is labor-intensive and has poor precision. It is impossible to know whether the applied pressure really meets the quality requirements, and it is impossible to fully ensure the quality of LCD panel products. [0003] Another detection method is to use a pressure bar instead of the above-mentioned ...
