Problems solved by technology

[0003] However, there is often a problem in the actual test: the stress tester cannot sense whether the screen is damaged, but just repeatedly exerts pressure on the screen. Once the screen is damaged, repeated stress tests are useless

Embodiment Construction

[0011] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0012] The intelligent sensing pressure tester of the present invention has the same basic structure as the existing pressure tester: it includes a motor, a tester body, and a test platform. The most important difference is that it has an intelligent sensing function and can perceive Whether the screen is damaged, so as to stop the destructive test in time, and record the pressure when the screen is damaged and the number of pressure withstand times under a certain pressure.

[0013] see figure 1 , The pressure tester of the present invention also includes: a probe for applying pressure controlled by a motor, an amplifier and a PLC (programmable logic controller). Among them, the probe is connected to the main body of the tester and located above the test platform. There is a force sensor inside the probe. The force sensor collects the f...

Abstract

The invention discloses an intelligent sensing pressure tester, which includes a motor, a main body of the tester, and a test platform, and is characterized in that it also includes: a measuring head for applying pressure controlled by the motor, an amplifier and a PLC, the measuring head and the The main body of the tester is connected and located above the test platform. There is a force sensor inside the above-mentioned measuring head. The above-mentioned force sensor collects the force signal in real time and transmits the signal to the amplifier connected to it. The above-mentioned amplifier feeds back the signal to the PLC. The above-mentioned PLC is connected to the motor and Control the motor to run or stop according to the feedback signal. The benefits are: 1. It can reliably judge when the screen is damaged and control the shutdown of the pressure tester; 2. Record the pressure when the screen is damaged, and at the same time record the withstand voltage times of the screen under a certain pressure.

Description

technical field [0001] The invention relates to a pressure tester, in particular to an intelligently sensed pressure tester. Background technique [0002] Notebooks, MP3s, MP4s, etc. need to test the pressure resistance of their screens after they are manufactured. The equipment used is a pressure tester. The basic principle is to use a probe to apply a preset force to the screen for a set number of times. Test, and finally observe whether the screen is damaged to determine the pressure resistance of the screen. [0003] However, there is often a problem in actual testing: the stress tester cannot sense whether the screen is damaged, but just repeatedly applies pressure to the screen. Once the screen is damaged, repeated stress tests are useless. Contents of the invention [0004] In order to solve the deficiencies of the prior art, the object of the present invention is to overcome the deficiencies of the prior art, and provide an intelligent sensory pressure tester, whi...
