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

[0013] The following describes the present invention in detail with reference to the drawings and specific embodiments.

[0014] The intelligent sensing pressure tester of the present invention has the same basic structure as the existing pressure tester: including the motor, the main body of the tester, and the test platform. The most important difference is that it has the intelligent sensing function and can sense the pressure test process. Whether the screen has been damaged, stop the destructive test in time, and record the pressure when the screen is damaged and the number of pressure resistance under a certain pressure.

[0015] 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 is located above the test platform. There is a force sensor inside the probe. The force sensor col...

Abstract

The invention discloses a pressure tester with an intelligent sensing function. The pressure tester comprises a motor, a tester main body and a testing platform, and is characterized by further comprising a measuring head, an enlarger and a PLC (programmable logic controller), wherein the measuring head is controlled by the motor, is used for applying pressure, is connected with the tester main body and is positioned above the testing platform, a force sensor is arranged in the measuring head, acquires force signals in real time and transmits the signals to the enlarger connected with the force sensor, the enlarger feeds back the signals to the PLC, and the PLC is connected with the motor and controls the motor to run or stop according to the fed-back signals. The pressure tester has the advantages that damage moment of a screen can be reliably judged, and the pressure tester can be reliably controlled to stop; pressure on the screen is recorded when the screen is damaged, and pressure resisting times of the screen under certain pressure can be recorded.

Description

Technical field [0001] The invention relates to a pressure tester, in particular to a pressure tester with intelligent perception. 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 to perform a set number of pressures. 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 reality testing: the stress tester cannot perceive whether the screen has been damaged, and just repeatedly applies pressure to the screen. Once the screen is damaged, repeated stress tests are just futile. Summary of the invention [0004] In order to solve the deficiencies of the prior art, the purpose of the present invention is to overcome the deficiencies of the prior art and provide an intelligent sensing...
