Aluminum silicon tempered glass low-temperature fatigue detecting device

Abstract

The invention discloses an aluminum silicon tempered glass low-temperature fatigue detecting device. A pressure difference is formed through conversion of air pumping and air inflation so that tempered glass carries out reciprocating deformation and bending under stress, and at the same time, a low temperature formed by vacuum extraction air compression is combined to form a low temperature environment through an effect of a refrigerant, and then fatigue detection is performed by the device. Bending detection is performed on a whole plane of the glass in a reciprocating mode so that detectionis more comprehensive. A refrigerant baffle ring is placed at a middle position of a pedestal, an inner diameter of the refrigerant baffle ring is gradually increased from bottom to top, and a main body cover is placed outside the refrigerant baffle ring. A bottom end of the main body cover is provided with a sealing press plate, and is pressed on the pedestal. A sealing ring is arranged between the sealing press plate and the pedestal. A top of the main body cover is an arc structure, and a limiting ring is placed on an inner wall of the main body cover. An annular clamping slot is formed onthe limiting ring, a width of the annular clamping slot is gradually reduced from the outside to the inside, and a rubber pad is arranged on a slot wall of the annular clamping slot. A pressing sleeveis arranged on the inner wall of the main body cover and is screwed to the main body cover.

Description

technical field [0001] The invention relates to a low-temperature fatigue detection device for aluminum-silicon tempered glass, which relates to a low-temperature fatigue detection device for aluminum-silicon tempered glass, and belongs to the field of material detection. In particular, it relates to a pressure difference formed by the transformation of air pumping and air charging, which makes the toughened glass reciprocatingly deformed and bent, and at the same time cooperates with the low temperature formed by vacuum pumping and air compression, and combines the action of refrigerant to form a low temperature environment for fatigue testing.

[0002] At present, with the popularization and promotion of electronic products, the use of electronic screens is becoming more and more extensive. Mobile phone touch screens, flat screens, etc., with the needs of users' sensory experience, more and more curved screens and bending screens have been developed. The requirements for the screen are getting higher and higher, especially the bending life and its strength. Some of them need to be used in the outdoor low temperature environment, so the requirements for the screen are very high. At present, the screens of mobile phones and tablets mainly use tempered Glass, of which aluminum-silicon alloy tempered glass is the most common, its wear resistance and bending resistance are stronger than other types of tempered glass, and its thickness is thinner. However, with the emergence of folding screens, the bending of tempered glass requires reciprocating Test, the traditional three-point and four-point bending test of the testing machine is suitable for metal and general plastic parts. After the fixture is adjusted left and right, the support rod is fixed. The result is not accurate enough, and some testing machines with high testing precision in the prior art have too complicated structure, not only high cost, but also cumbersome operation

[0003] Publication number CN205580857U discloses a mobile phone glass bending testing machine, comprising a testing machine body, a moving beam, an upper assembly and a lower assembly; the moving beam is installed between two guide rails on the top of the testing machine body; the upper assembly includes an upper connector, an upper connector plate and upper support bar, the upper connection head is fixedly connected with the moving beam, the upper connection plate is fixedly connected with the upper connection head, and the upper support rod is fixed on the upper connection plate by a rotating shaft; the lower end assembly includes a lower connection head, a lower fixture, two lower The connection plate, the lower support rod and the lower adjustment handwheel, the lower connection head is fixed on the top of the testing machine body in a rotatable manner, the lower fixture is fixedly connected with the lower connection head, and the lower adjustment handwheel drives the two lower connection plates with a screw rod Movement, the lower support rod is fixed on the lower connecting plate by the rotating shaft, the structure of the device is complicated, the operation is inconvenient, and it cannot detect the entire glass
