As shown in fig. 1 to 7, according to a first aspect of the present utility model, there is provided a conveying apparatus, which may be one or more of a loading mechanism, a conveying mechanism and a discharging mechanism, for conveying a workpiece (e.g., a hard brittle material such as a silicon rod) to a specified position (e.g., to a cutting mechanism for cutting).

Specifically, the conveying device of the utility model comprises a roller assembly 100 for conveying workpieces and a mounting frame 130 connected with the roller assembly 100, wherein the roller assembly 100 rotates to achieve the purpose of moving the workpieces by utilizing friction force between the roller assembly 100 and the workpieces.

The number of the roller assemblies 100 is at least two, and the at least two roller assemblies 100 are arranged side by side. In the example shown in fig. 1, an example in which the number of the roller assemblies 100 is two is shown, and the two roller assemblies 100 are disposed opposite to each other (symmetrically disposed about the axis of the workpiece), so that the workpiece can be placed between the two roller assemblies 100, and the workpiece is moved in the axial direction thereof (the feeding direction shown by the arrow in fig. 1) by the rotation of the roller assemblies 100. The workpiece can be supported and transported on both sides in the axial direction of the workpiece by the two roller assemblies 100, thereby improving the stability of workpiece transport.

As shown in fig. 1 and 2, each roller assembly 100 includes a driving shaft 140, a first roller 110, and a second roller 120. The first roller 110 may be located at the conveyance start end, the conveyance end, or any position between the conveyance start end and the conveyance end of the conveyance, i.e., the position of the first roller 110 is not limited by the present utility model.

Optionally, the first roller 110 is located at a conveying start end of the conveying device, for example, the conveying device is a feeding device shown in fig. 1, and the conveying start end is an end a shown in fig. 1, from which the workpiece is fed. The number of first rollers 110 may be one or more. When the first roller 110 is located at the conveying start end of the conveying device, the second rollers 120 are located at the downstream side of the first roller 110.

Or alternatively, the first roller 110 may be further located at a conveying end, for example, the conveying device is a feeding device shown in fig. 1, and a conveying start end is a B end shown in fig. 1, where the workpiece enters a downstream component of the conveying device, for example, a conveying mechanism, or the like. The number of first rollers 110 may be one or more. When the first roller 110 is located at the conveying end of the conveying device, the second rollers 120 are located at the upstream side of the first roller 110.

Or further alternatively, the roller assembly 100 may also adopt a structural form that one (or more) of the first rollers 110 is located at the conveying start end of the conveying device, and the other (or more) of the first rollers 110 is located at the conveying end, so that impact leading-in/leading-out conditions can be formed both when the conveying device is led in and when the conveying device is led out, so that the workpiece can be smoothly led in/out of the conveying device, and the first rollers 110 can adjust the workpiece when the workpiece is led in/led out, which can play a transitional role. When the first roller 110 is located at the conveyance start end and the conveyance end of the conveyance device, respectively, the second roller 120 may be disposed between the first roller 110 at the conveyance start end and the first roller 110 at the conveyance end.

It will be appreciated that the roller assembly 100 may also take the form of a configuration in which the first roller(s) 110 are located elsewhere on the conveyor (e.g., in an intermediate position, etc.). Alternatively, the roller assembly 100 may also take the form of a structure in which one (or more) of the first rollers 110 is located at other positions of the conveying device and the other (or more) of the first rollers 110 is located at the conveying start end (or conveying end) of the conveying device.

Alternative embodiments of the first roller 110 at different locations on the conveyor may be freely combined.

The first roller 110 is configured as an unpowered roller that is freely rotatable; in contrast, the second roller 120 is configured as a powered roller, i.e., it requires powered rotation to move the workpiece, unlike the first roller 110. By utilizing the friction force between the second roller 120 and the workpiece, the rotation of the second roller 120 can drive the workpiece to move, and on the basis, the friction force can be generated between the workpiece and the first roller 110 due to the movement of the workpiece, so that the first roller 110 can rotate in turn due to the movement of the workpiece, and the impact-free guiding condition of the workpiece can be formed due to the fact that the rotation of the first roller 110 is not caused by power driving, so that the workpiece can be guided into the conveying device smoothly. Therefore, during feeding, the second roller 120 rotates to drive the workpiece to move along the feeding direction, and meanwhile, the workpiece firstly contacts with the feeding starting end of the conveying device, so that the workpiece can be smoothly guided into the conveying device under the impact-free condition by arranging the first roller 110 at the feeding starting end of the conveying device; similarly, since the workpiece is required to be transferred from the end of loading to the downstream component of the conveyor (e.g., the conveyor mechanism) when the workpiece is moved to the end of loading, the first roller 110 is also provided at the end of loading of the conveyor, and the workpiece can be smoothly introduced into the conveyor mechanism without impact when the workpiece is transferred from the conveyor to the downstream component thereof.

It will be appreciated that a plurality of first rollers 110 may also be provided at each end of each roller assembly.

As shown in fig. 2, the driving shaft 140 is connected to the second roller 120 through a bevel gear assembly 141 to rotate the second roller 120. For example, the bevel gear assembly 141 may include a bevel gear disposed on the drive shaft 140 and a bevel gear engaged with the second roller 120, whereby power of the drive shaft 140 may be transmitted to each of the second rollers 120. In addition, since the axial direction of the driving shaft 140 extends in the feeding direction of the workpiece, by providing the bevel gear, the axial vertical arrangement (perpendicular to the axial direction of the driving shaft 140) of each second roller 120 can be achieved, thereby improving the smoothness of the movement of the workpiece.
