[0024] Reference Figure 1 and Figure 2 , Figure 1 is an axonometric view of the fatigue testing device of the first embodiment, Figure 2 yes Figure 1 The fatigue testing device in this embodiment includes two fatigue testing devices, the fatigue testing devices include a first bending assembly 100, a second bending assembly 200 and a frame 300, and the two fatigue testing devices share one frame 300. By setting up two fatigue testing devices at the same time, fatigue tests of two pieces of glass can be performed at the same time, thereby improving the test efficiency.

[0025] Reference Figures 2 to 5 , Figure 3 yes Figure 1 An axonometric view of the first bending assembly 100 in FIG. Figure 4 yes Figure 3 A partial enlarged view of the middle Ⅰ area. Figure 5 yes Figure 1Exploded view of the first bending assembly 100 in FIG. The first bending assembly 100 and the second bending assembly 200 cooperate with each other to complete the bending action together. The first bending assembly 100 includes a first driving device, a first mounting seat 130, a first connecting member 140, a first bending plate 150, a first limit block 160, a first micrometer 170, a first mounting plate 180, a first bolt and a first nut, wherein the first driving device includes a first motor 110 and a first reducer 120. The housing of the first motor 110 is fixed to the housing of the first reducer 120 by screw locking, and the housing of the first reducer 120 is fixed to the first mounting seat 130 by screw locking, and the first mounting seat 130 is fixed to the frame 300 by screw locking.

[0026] The rotating shaft of the first motor 110 is fixedly connected to the input shaft of the first reducer 120 (connected by a coupling or a sleeve). The output shaft of the first reducer 120 is fixedly connected to the first connecting member 140. A first keyway is provided on the output shaft of the first reducer 120, and a connecting hole is provided on the first connecting member 140, and a second keyway is provided on the inner surface of the hole. The output shaft of the first reducer 120 is inserted into the connecting hole, and at the same time, the two parts of the key are respectively placed in the first keyway and the second keyway, so that the output shaft of the first reducer 120 is fixedly connected to the first connecting member 140.

[0027] Therefore, when the first motor 110 is powered on, the first connecting member 140 will rotate around the first axis, which is the rotation axis of the output shaft of the first reducer 120 .

[0028] In another embodiment, the first driving device may also be a rotary cylinder.

[0029] The front side of the first connecting member 140 is provided with a first slide groove 141. The first bending plate 150 is a rectangular plate, and the first bending plate 150 is provided with adjacent first ends (i.e., the left end) and second ends (i.e., the rear end), and the second end (i.e., the rear end) of the first bending plate 150 is placed in the first slide groove 141. There is a non-zero angle between the direction in which the first bending plate 150 slides along the first slide groove 141 and the first axis. Therefore, after the first bending plate 150 slides along the first slide groove 141, the first bending plate 150 will have at least one displacement component in the direction perpendicular to the first axis, and the displacement component is the adjustment amount of the bending radius or the bending position. In this embodiment, the direction in which the first bending plate 150 slides along the first slide groove 141 is the left-right direction, the first axis is set along the front-back direction, and the direction in which the first bending plate 150 slides along the first slide groove 141 is perpendicular to the first axis. At this time, the displacement of the first bending plate 150 sliding along the first slide groove 141 is the adjustment amount of the bending radius or the bending position.

[0030] The first bending plate 150 is detachably fixed to the first connecting member 140. Specifically, a first threaded hole can be provided on the first clamping block above the first slide slot 141, the first threaded hole is connected to the first slide slot 141, and a screw is passed through the first threaded hole. After the screw is rotated, the screw and the second clamping block below the first slide slot 141 clamp the first bending plate 150, or the screw and the second clamping block below the first slide slot 141 release the first bending plate 150. In addition, the first clamping block above the first slide slot 141 can also be directly set to be movable, the first clamping block is provided with a first through hole, the second clamping block is provided with a second threaded hole, and the screw passes through the first through hole and then is threadedly matched with the second threaded hole. After the screw is rotated, the first clamping block and the second clamping block clamp the first bending plate 150, or the first clamping block and the second clamping block release the first bending plate 150.

[0031] The upper surface of the first bending plate 150 is a first working surface 151, and the first working surface 151 is used to place glass. A first stopper 160 is provided on the first working surface 151, and the first stopper 160 is provided at the right end of the first bending plate 150, and the first stopper 160 is used to abut against the right end of the glass to prevent the glass from being separated from the first bending plate 150 when being bent.

[0032] In order to prevent the right end of the glass from moving rightward and upward at the same time, a first groove 161 is provided on one side of the first limit block 160 facing the first end of the first bending plate 150 (see Figure 4 ). Thus, when the glass is placed on the first working surface 151, the right end of the glass will be inserted into the first groove 161, and the first groove 161 limits the right end of the glass to prevent the glass from being separated from the first bending plate 150 when being bent.

[0033] In another embodiment, a receiving groove may be formed on the upper surface of the first bending plate 150 , and the glass is placed in the receiving groove, with the right end of the glass abutting against the right end surface of the receiving groove. In this case, the receiving groove may also prevent the glass from detaching from the first bending plate 150 .

[0034] The first micrometer 170 is located on the left side of the first connecting member 140. The first micrometer 170 includes a first micrometer screw 171 and a first fixed scale portion 172. The first fixed scale portion 172 is fixed to the first mounting plate 180. The fixing method can be an interference fit method. The first mounting plate 180 is locked on the first mounting seat 130 by screws.

[0035] The first micrometer screw 171 faces the first bending plate 150. After the first micrometer screw 171 is extended, it can abut against the first end (i.e., the left end) of the first bending plate 150. Therefore, when the first bending plate 150 and the first connecting member 140 are not fixed, the first micrometer screw 171 is extended until the first micrometer screw 171 contacts the first end (i.e., the left end) of the first bending plate 150. At this time, the first reading of the first micrometer 170 can be recorded. Continue to extend the first micrometer screw 171 to the right, the first micrometer screw 171 will push the first bending plate 150 to move to the right, and after the first micrometer screw 171 extends one end distance (this distance), the first bending plate 150 and the first connecting member 140 are fixed. At this time, the second reading of the first micrometer 170 is recorded. By comparing the two readings, the distance moved by the first bending plate 150 along the first slide 141 can be accurately known.

[0036] In addition, after the first micrometer screw 171 contacts the first end (i.e., the left end) of the first bending plate 150, the first micrometer screw 171 may be rotated to retract the first micrometer screw 171 by one end, and then the first bending plate 150 may be moved leftward along the first slide groove 141 until the first micrometer screw 171 contacts the first end (i.e., the left end) of the first bending plate 150 again. At this time, by presetting the retracted distance of the first micrometer screw 171, the moving distance of the first bending plate 150 along the first slide groove 141 may also be accurately determined.

[0037] When the position of the first limit block 160 on the first working surface 151 remains unchanged and the glass is always in contact with the first limit block 160, the first bending plate 150 moves to the right or left relative to the first connecting member 140, which will change the position of the glass relative to the first axis (in this embodiment, the first axis is the rotation axis of the output shaft of the first reducer 120), that is, the bending radius or bending position of the glass changes, and the changed value can be accurately determined by the first micrometer 170 with an accuracy of up to 0.01mm.

[0038] In order to determine the bending radius of the glass in conjunction with the first micrometer 170, a first scale 153 is provided on one side of the first working surface 151 close to the first connecting member 140. The graduation value of the first scale 153 is 1 mm, which is equivalent to an ordinary scale. After the glass is placed on the first working surface 151, the bending radius of the glass can be calculated by comparing the position of the right end of the glass on the first scale 153 and combining the position of the rotation axis of the output shaft of the first reducer 120 (the rotation axis of the output shaft of the first reducer 120 is fixed relative to the frame 300).

[0039] In order to adapt to glass of different lengths, the position between the first limit block 160 and the first axis can be adjusted. Specifically, a waist-shaped hole 152 is provided on the first bending plate 150, and the length direction of the waist-shaped hole 152 is arranged along the left-right direction. A first through hole is provided on the first limit block 160. After the first bolt passes through the first through hole and the waist-shaped hole 152, it is threadedly matched with the first nut, thereby clamping the first limit block 160 on the first bending plate 150. When it is necessary to adjust the position of the first limit block 160, loosen the first nut to move the first limit block 160 along the waist-shaped hole 152. After reaching the predetermined position, tighten the first nut again to complete the position adjustment of the first limit block 160.

[0040] In this embodiment, the structure of the second bending assembly 200 is exactly the same as that of the first bending assembly 100, and the first bending assembly 100 includes a second driving device, a second mounting seat, a second connecting member, a second bending plate, a second stopper, a second micrometer, a second mounting plate, a second bolt and a second nut, wherein the second driving device includes a second motor and a second reducer. The third end (i.e., the right end) of the second bending plate is adjacent to the first end (i.e., the left end) of the first bending plate 150, and there is a gap. The second connecting member is connected to the rotating shaft of the second motor through the second reducer, and the rotation axis of the second connecting member is the second axis (in this embodiment, the second axis is the rotation axis of the output shaft of the second reducer). The second axis is collinearly arranged with the first axis, that is, the rotation axis of the output shaft of the first reducer is collinear with the rotation axis of the output shaft of the second reducer, thereby, the bending position of the glass is located at the first axis. When the second axis is not collinear with the first axis, the bending position of the glass is located between the first axis and the second axis.

[0041] Thus, the first bending assembly 100 can bend a portion of the glass by 90°, and the second bending assembly 200 can bend another portion of the glass by 90°, and a single fatigue testing device can bend the glass by 180°. In addition, a single fatigue testing device can bend the glass by 90° or 120°.

[0042] In another embodiment, the second bending assembly 200 may also include only a second bending plate, and the second bending plate is placed horizontally. The second bending plate does not rotate, and the first bending assembly 100 bends a portion of the glass by 180°. In this case, the fatigue testing device can also complete the fatigue test of the glass.

[0043] In addition, the first bending assembly 100 and the second bending assembly 200 of a single fatigue testing device can be arranged in a box to prevent accidental breakage of the glass during bending, which may lead to installation accidents. A CCD camera can also be installed above the first bending assembly 100 and the second bending assembly 200. The CCD camera can take pictures of the glass on the first working surface 151 and the second working surface of the second bending plate. When the glass is accidentally broken, the CCD camera can take pictures for identification, thereby alerting the staff.

[0044] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present invention. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
