[0023] Referring to Figures 1 to 3 , Figure 1 is an isometric view of the bending test device of the first embodiment, Figure 2 is Figure 1 an enlarged schematic view of region Ⅰ in Figure 3 is Figure 1Exploded view of the middle bending test device. The bending test device of this embodiment includes a first loading platform assembly 100, a connection assembly 200, and a second loading platform assembly 300. The first loading platform assembly 100 includes adjusting screws 110, a first base 120, a collision pad 130, a first adjusting assembly 140, and a first loading platform 150. The second loading platform assembly 300 includes a second base 310, a second adjusting assembly, and a second loading platform 320. Among them, one end of the first base 120 in the negative Z-axis direction is its first end, and one end of the first base 120 in the positive Z-axis direction is its second end. Similarly, one end of the second base 310 in the negative Z-axis direction is its first end, and one end of the second base 310 in the positive Z-axis direction is its second end. The first end of the first base 120 and the second end of the second base 310 are rotationally connected through the connection assembly 200.

[0024] The first loading platform 150 is located on the side of the first base 120 in the positive Y-axis direction. A first working surface 151 is provided on the first loading platform 150. A first clamping platform 152 is provided on the side of the first working surface 151 in the positive Y-axis direction. The first working surface 151 can be attached to the bottom surface of the ultra-thin glass 400, so that the ultra-thin glass 400 is placed flat on the first loading platform 150. The first clamping platform 152 can abut against the end surface of the ultra-thin glass 400, preventing the ultra-thin glass 400 from undergoing relative movement with the first loading platform 150 due to bending during the rotation of the first base 120 relative to the second base 310, which affects the detection of the bending performance of the ultra-thin glass 400. Similarly, the second loading platform 320 is located on the side of the second base 310 in the positive Y-axis direction (refer to Figure 3 ), a second working surface 321 is provided on the second loading platform 320. A second clamping platform 323 is provided on the side of the second working surface 321 in the positive Y-axis direction. The second working surface 321 and the first working surface 151 jointly support the ultra-thin glass 400. The second clamping platform 323 and the first clamping platform 152 jointly position the ultra-thin glass 400, preventing the ultra-thin glass 400 from moving during the bending process.

[0025] To better fix the ultra-thin glass 400 on the first loading platform 150 and the second loading platform 320, a first groove is provided on the first clamping platform 152, and a second groove 322 is provided on the second clamping platform 323. The two ends of the ultra-thin glass 400 are respectively placed in the first groove and the second groove 322. The first groove can prevent the end of the ultra-thin glass 400 from detaching from the first clamping platform 152, and the second groove 322 has the same function.

[0026] To enable the first stage 150 to approach or move away from the first end of the first base 120, so as to adjust the position of the ultra-thin glass 400 relative to the first stage 150, and further adjust the bending position of the ultra-thin glass 400, a first adjustment assembly 140 is provided. Specifically, the first adjustment assembly 140 includes an adjustment rod 141, a gear 142, a rack 143, a slider 144 and a slide rail 145. A receiving groove 121 is provided on the first base 120. The first stage 150 is placed in the receiving groove 121, and the first working surface 151 is flush with the surface of the first base 120 on the positive Y-axis side, so that the first stage 150 and the first base 120 jointly carry the ultra-thin glass 400.

[0027] The slider 144 is locked and fixed on the surface of the first stage 150 on the negative Y-axis side, and the slide rail 145 is locked and fixed on the bottom surface of the receiving groove 121. The slider 144 is in sliding fit with the slide rail 145, and the length direction of the slide rail 145 is arranged along the Z-axis direction. Thus, the sliding connection between the first stage 150 and the first base 120 is realized, and the first stage 150 can move relative to the first base 120 in a direction close to or away from the first end of the first base 120.

[0028] To adjust the position of the first stage 150 relative to the first base 120, an adjustment rod 141, a gear 142 and a rack 143 are provided. First, an adjustment hole 123 is provided on the first base 120. The adjustment rod 141 is placed in the adjustment hole 123, and the adjustment rod 141 is in clearance fit with the adjustment hole 123, so as to realize the rotational connection between the adjustment rod 141 and the first base 120. The gear 142 is fixed on the adjustment rod 141. The fixing method can be to set a key on the adjustment rod 141 and a keyway on the gear 142 to realize the fixation of the two. The rack 143 is fixed on the surface of the first stage 150 on the negative Y-axis side. The gear 142 meshes with the rack 143. By rotating the knob 146 on the positive X-axis side of the adjustment rod 141, the first stage 150 can be made to approach or move away from the first end of the first base 120, so as to realize the adjustment of the bending position of the ultra-thin glass 400.

[0029] Refer to Figure 1 、 Figure 3 and Figure 4 , Figure 4 is Figure 1 a working schematic diagram of the bending test device in Figure 4), a connecting assembly 200 is provided, and the connecting assembly 200 includes a fixing screw 210, a connecting piece 220, a butterfly nut 230 and a rotating shaft 240, wherein the fixing screw 210, the connecting piece 220 and the butterfly nut 230 are provided in two groups, and the rotating shaft 240 is provided with one, and the two groups of fixing screws 210, connecting pieces 220 and butterfly nut 230 are respectively provided at both ends of the rotating shaft 240. The connecting piece 220 is provided with a locking hole 221 at one end in the positive direction of the Z axis (refer to Figure 3 ), after the fixing screw 210 passes through the locking hole 221, it is threadedly matched with the first base 120, and the fixing screw 210 and the locking hole 221 are clearance-matched, thereby making the connecting piece 220 rotatably connected to the first base 120.

[0030] The second end of the second base 310 is provided with a shaft hole, and the shaft 240 is placed in the shaft hole. The shaft 240 and the shaft hole are in clearance fit, and a clamp ring is fixed to each of the two ends of the shaft 240 in the X-axis direction (refer to Figure 3 , annular grooves can be opened at both ends of the rotating shaft 240, and the retaining rings can be embedded in the annular grooves to fix the retaining rings on the rotating shaft 240). As a result, the second base 310 can rotate relative to the rotating shaft 240, and the second base 310 will not be separated from the rotating shaft 240. After the end of the rotating shaft 240 passes through the waist-shaped hole 222, it is threadedly matched with the butterfly nut 230, and the butterfly nut 230 and the retaining ring jointly clamp the connecting piece 220, thereby realizing the detachable fixation of the rotating shaft 240 and the connecting piece 220.

[0031] By loosening and tightening the butterfly nut 230, the position of the rotating shaft 240 in the waist-shaped hole 222 can be adjusted (that is, the position of the second base 310 relative to the first base 120 is adjusted). When the second base 310 is parallel to the first base 120 (refer to Figure 4 ), the bending radius R of the ultra-thin glass 400 will have different values, that is, the adjustment of the bending radius R of the ultra-thin glass 400 is achieved.

[0032] In another embodiment, a nut may be provided on both sides of the connecting piece 220 , and both nuts are threadedly connected to the rotating shaft 240 , so that the rotating shaft 240 can be detachably fixed to the connecting piece 220 , and at the same time, the second base 310 can be prevented from being separated from the rotating shaft 240 .

[0033] When adjusting the position of the adjusting rotating shaft 240 in the waist-shaped hole 222, to ensure that the second base 310 and the first base 120 are parallel, and to ensure that the ultra-thin glass 400 has no other bends (such as bending around the Z-axis) except for bending around the X-axis, adjusting screws 110 are provided. There are at least more than 3 adjusting screws 110. The adjusting screws 110 are in threaded cooperation with the first base 120, and one end of the adjusting screw 110 in the positive Y-axis direction can protrude from the first base 120 so as to abut against the second base 310. By observing the scale on the adjusting screw 110, the lengths of the one ends of the adjusting screws 110 protruding from the first base 120 in the positive Y-axis direction are made the same. According to the principle that three points determine a plane, the second base 310 and the first base 120 are made parallel, thereby ensuring the accuracy of the bending radius R of the ultra-thin glass 400.

[0034] In this embodiment, 4 adjusting screws 110 are provided, and the 4 adjusting screws 110 are evenly distributed at the four corners of the first base 120.

[0035] On one side of the first base 120 in the positive Y-axis direction, an anti-collision pad 130 is further provided. When the second base 310 rotates too much and contacts the first base 120, at this time, the anti-collision pad 130 can play a buffering role to prevent damage to the first base 120 and the second base 310.

[0036] To limit the rotation angle of the connecting piece 220 relative to the first base 120 and ensure the accurate bending of the ultra-thin glass 400 (refer to Figure 4 ), a holding seat 122 is provided on the first base 120 (refer to Figure 1 ). When the connecting piece 220 contacts the holding seat 122, the side surface of the connecting piece 220 is perpendicular to the surface of the first base 120 in the positive Y-axis direction (refer to Figure 4 ).

Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present invention.
