[0039] In order to collect the broken materials of the substrate glass, a discharge plate 24 is provided at the bottom end of the two crushing assemblies 3, and the discharge plate 24 is an inclined structure. A discharge port 22 is opened on the side of the detection box 2; the discharge plate 24 is connected to the discharge port 22; a baffle 23 is provided on the side of the detection box 2; the baffle 23 is adapted to the other crushing assembly 3, and the baffle 23 blocks the substrate glass to ensure that the substrate glass enters between the two crushing assemblies 3 to be crushed.

[0040] In order to prevent a large piece of glass from being stuck in the detection box 2 and unable to enter the crushing assembly 3, the present invention further includes a crushing assembly 9, which includes a crushing motor 91, a rotating ring 92, a connecting rope 93, a crushing head 94, a winding motor 95, a winding shaft 96 and an extension plate 97; Figure 5 and Figure 6As shown, a crushing motor 91 is installed at the center of the other side of the cross bar 71, and the output end of the crushing motor 91 is connected to a rotating ring 92; the rotating ring 92 is rotatably connected to the cross bar 71, and the inside of the rotating ring 92 is rotatably connected to a reel 96; the side of the reel 96 is connected to a reel motor 95, and a connecting rope 93 is wound around the outside of the reel 96; the end of the connecting rope 93 is connected to a crushing head 94, and a cone block 941 is distributed on the outside of the crushing head 94.

When the crushing motor 91 is started, it can drive the rotating ring 92 to rotate in the cross bar 71, so that the crushing head 94 rotates at a high speed in the detection box 2 and hits the substrate glass to crush it. The top of the detection box 2 is detachably connected to an outer shield 1, which is used to protect the detection.

[0041] When the device of the present invention is used, the substrate glass to be tested is first fed into the detection box 2 through the feed opening 22.

After the support plate 41 descends, the groove 431 on the side of the baffle plate 2 43 is matched with the crushing assembly 3. At this time, the substrate glass falls under the action of gravity. When the substrate glass falls, the clamping assembly 8 clamped with the substrate glass is pulled to drive the slider 84 to approach each other.

When the rotating motor 63 is started, the screw rod 62 is driven to rotate. When the screw rod 62 rotates The two nuts 61 are driven to approach each other, and the two nuts 61 move close to each other so as to contact and bring the two clamping assemblies 8 close to each other, so that the glass is broken under the force on both sides.

When processing, the crushing assembly 9 is first started to crush the large pieces of glass, and the winding motor 95 is started. When the winding motor 95 is started, the connection The rope 93 stretches, and then the crushing motor 91 is started. When the crushing motor 91 is started, it can drive the rotating ring 92 to rotate in the cross bar 71, so that the crushing head 94 rotates at high speed in the detection box 2 and hits the substrate glass to crush it; the broken glass goes along the arc-shaped support plate 41 and enters between the two crushing assemblies 3 under the obstruction of the baffle 1 23 and the baffle 2 43, and the crushing assemblies 3 are started to make the two crushing assemblies 3 work, that is, the crushing motor 31 is started. When the crushing motor 31 is started, it drives the crushing shaft 33 to rotate, and then the two sets of crushing blades 32 are used to rotate inward to crush the substrate glass.
