With the buffer belt made of elastic materials carrying such hard workpieces as glass to be transferred, when the guide device is in contact with the hard workpiece to be transferred, the buffer belt is pressed to deform, which can reduce the pressure produced during the contact of the guide device with the hard workpiece, and prevent the contact portion from being broken or worn because of the pressure, not only preventing loss of the hard workpiece to be transferred, but also reducing use consumption of the guide device, thereby reducing the material cost. ## Claims ### Claim 1 A guide device for hard workpiece transfer, comprising a buffer belt for carrying a hard workpiece, a pilot wheel for driving the buffer belt to move, and a drive device for controlling the pilot wheel to rotate, with the buffer belt being made of elastic materials. ### Claim 2 (depends on 1) The guide device of claim 1, wherein the buffer belt is provided with a clamping portion for clamping the hard workpiece. ### Claim 3 (depends on 2) The guide device of claim 2, wherein the clamping portion includes a tooth-like bulge at both ends of the buffer belt, with a middle portion of the buffer belt as a deformation zone; when the hard workpiece presses the deformation zone of the buffer belt during transfer, both ends of the buffer belt close up to the middle, until an inner side of the tooth-like bulge at both ends of the buffer belt completely fits the hard workpiece. ### Claim 4 (depends on 2) The guide device of claim 2, wherein the clamping portion includes an occlusal pad respectively bonded to both ends of the buffer belt, with a middle portion of the buffer belt as a deformation zone; when the hard workpiece presses the deformation zone of the buffer belt during the transfer, both ends of the buffer belt drives the occlusal pad to close up to the middle, until the inner side of the occlusal pad completely fits the hard workpiece. ### Claim 5 (depends on 4) The guide device of claim 4, wherein there is a descending slope respectively from both ends of the buffer belt to the middle, and the deformation zone of the buffer belt is formed by two intersecting slopes, with the inner side of the occlusal pad being a slope. ### Claim 6 (depends on 4) The guide device of claim 4, wherein the buffer belt is a plane, with the inner side of the occlusal pad being a plane. ### Claim 7 (depends on 4) The guide device of claim 4, wherein the occlusal pad is made of antiskid materials. ### Claim 8 (depends on 7) The guide device of claim 7, wherein the width of the deformation zone of the buffer belt is close to the thickness of the workpiece. ### Claim 9 (depends on 1) The guide device of claim 1, wherein the drive device is a drive shaft, to which the pilot wheel is fixed, with the buffer belt muff-coupled to at least two pilot wheels. ### Claim 10 (depends on 1) The guide device of claim 1, wherein the drive device is a chain, to which the pilot wheel is fixed, with the buffer belt respectively bonded to the single pilot wheel. ### Claim 11 A guide device for hard workpiece transfer, comprising a buffer belt for carrying the hard workpiece, a pilot wheel for driving the buffer belt to move, and a drive device for controlling the pilot wheel to rotate, the buffer belt being provided with a clamping portion for clamping the hard workpiece, the buffer belt being made of elastic materials. ### Claim 12 (depends on 11) The guide device of claim 11, wherein the clamping portion includes a tooth-like bulge at both ends of the buffer belt, with a middle portion of the buffer belt as a deformation zone; when the hard workpiece presses the deformation zone of the buffer belt during the transfer, both ends of the buffer belt close up to the middle, until the inner side of the tooth-like bulge at both ends of the buffer belt completely fits the hard workpiece. ### Claim 13 (depends on 11) The guide device of claim 11, wherein the clamping portion includes an occlusal pad respectively bonded to both ends of the buffer belt, with a middle portion of the buffer belt as a deformation zone; when the hard workpiece presses the deformation zone of the buffer belt during the transfer, both ends of the buffer belt drives the occlusal pad to close up to the middle, until the inner side of the occlusal pad completely fits the hard workpiece.
