Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0038] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0039] With reference to the accompanying drawings, the present embodiment provides a silicon ingot edge skin rapid film wrapping device, which includes a frame 1, a support 2, a rotating ring 3 and a film wrapping roller 4. The frame 1 is provided with a controller and a control key (not shown in the figure) for cooperating with the start and stop of the rotating ring 3 and other structures; the support 2 and the rotating ring 3 are both arranged on the frame 1, and the film wrapping roller 4 is located on the rotating ring 3 and rotates with the rotating ring 3; the support 2 is located on both sides of the rotating ring 3 along the axis direction. When in use, the support 2 is used to place the silicon ingot edge skin, and the film wrapping roller 4 is used to install the packaging film roll. When the rotating ring 3 rotates, the film wrapping roller 4 and the packaging film roll thereon rotate accordingly to wrap the packaging film around the silicon ingot edge skin on the support 2. In order to prevent the film wrapping roller 4 and the packaging film roll from hitting the lower side of the silicon ingot or the support 2 and stopping the rotation, the support 2 should be set higher than the inner bottom surface of the rotating ring 3, and the distance between the support 2 and the rotating ring 3 should be greater than the length of the film wrapping roller 4 and the packaging film roll.

[0040] The frame 1 includes a base 1-10 and a stand 1-20, both of which have mounting cavities therein for accommodating and mounting the driving device of the rotating ring 3. The stand 1-20 is disposed on the top surface of the base 1-10, and a circular mounting hole 1-21 is disposed in the center thereof for mounting the rotating ring 3, while the support 2 is disposed on the base 1-10 on both sides of the rotating ring 3. It is feasible that the support 2 can be integrally formed with the top surface of the base 1-10, or it can protrude from the top surface of the base 1-10. When the former solution is adopted, the bottom of the rotating ring 3 should be located below the top surface of the base 1-10 and inside the installation cavity of the base 1-10. Therefore, a rotating channel 1-11 (i.e., a hole) should be set on the top surface of the base 1-10 near the rotating ring 3 (refer to the accompanying drawings), so that the film roller 4 and the packaging film roll thereon can move along the rotation direction and enter and exit the installation cavity of the base 1-10 through the rotating channel 1-11 to wrap the bottom surface of the silicon ingot edge skin on the support 2; when the latter solution is adopted, the height of the rotating ring 3 can be the same as the above configuration, or it can be completely located above the top surface of the base 1-10. At this time, the rotating channel 1-11 may not be set on the top surface of the base 1-10, so the probability of dust falling into its internal installation cavity is reduced, and the failure caused by the entry of external dust can be reduced.

[0041] The driving device of the rotating ring 3 includes a driving motor 5, a driving wheel 6 and a driven wheel 7. The driving motor 5, the driving wheel 6 and the driven wheel 7 are located in the mounting cavity inside the frame 1. The driving wheel 6 and the driven wheel 7 are distributed on the outer wall of the rotating ring 3. The output shaft of the driving motor 5 is connected to the driving wheel 6. When the driving motor 5 is in operation, the driving wheel 6 is driven to rotate. The rotating ring 3 is rotated by the friction force generated by the rotation of the driving wheel 6. The friction force generated when the rotating ring 3 rotates drives the driven wheel 7 to rotate. The driven wheel 7 provides support for the rotating ring 3. When the rotating ring 3 rotates, it also drives the outer film roller 4 to rotate to achieve film wrapping.

[0042] The number of driving wheels 6 and driven wheels 7 is configured according to actual needs, for example, according to the different rotational driving forces required by different rotating rings 3, and no specific restrictions are made here. In order to make the rotating ring 3 rotate stably, the driving wheels 6 and driven wheels 7 should be evenly distributed on the outside of the rotating ring 3 so that the various parts of the rotating ring 3 are subjected to balanced forces.

[0043] Referring to the accompanying drawings, the rotating ring 3 includes a transmission cylinder 3-10 and two wing ring plates 3-20. The transmission cylinder 3-10 is installed in the circular mounting hole 1-21 in the center of the frame 1, and is abutted against the driving wheel 6 and the driven wheel 7; the two wing ring plates 3-20 are respectively located at the two ends of the transmission cylinder 3-10, and the film roller 4 is arranged on the side of the wing ring plate 3-20 away from the transmission cylinder 3-10.

[0044] Since the film roller 4 and the packaging film roll thereon have a certain weight, in order to prevent uneven force on both sides of the rotating ring 3 along the axial direction and aggravate wear, in this embodiment, the same number of film rollers 4 are respectively provided on the two wing ring plates 3-20, and all the film rollers 4 are evenly distributed around the circumference of the transmission cylinder 3-10. On the one hand, film rollers 4 are provided on both sides of the rotating ring 3, and packaging film rolls are installed on the film rollers 4, which can not only balance the force on both sides of the rotating ring 3, but also fix the parts of the silicon ingot side skin located on both sides of the rotating ring 3, thereby improving the packaging stability.

[0045] Similarly, in order to improve the support and rotation stability, a removable slide 9 can be provided on the side of the wing ring plate 3-20 close to the transmission cylinder 3-10, and an annular slide 1-22 coaxial with the circular mounting hole 1-21 is provided on the side wall of the stand 1-20, and the removable slide 9 is slidably provided in the annular slide 1-22 on the stand 1-20. The number of removable slides 9 can be configured according to actual needs and evenly distributed along the circumference of the wing ring plate 3-20.

[0046] In addition, a limit piece 10 can be set on the side of the film roller 4 away from the rotating ring 3, and a driving assembly of the limit piece 10 can be set on the frame 1. The driving assembly can be used to drive the limit piece 10 to move radially along the rotating ring 3, so as to limit the side of the silicon ingot skin located on the supporting platform 2. Before wrapping the film, the side surfaces of the stacked silicon ingot skins can be pre-aligned, and during the wrapping process, the silicon ingot skins can be pressed against to prevent them from sliding, thereby improving the stability of the silicon ingot skins after wrapping and preventing them from loosening and sliding during transportation.

[0047] During implementation, the driving assembly can be configured to include a driving screw 11 and a slider 12, a strip slide 1-30 is arranged on the top of the base 1-10, the extension direction of the strip slide 1-30 is parallel to the radial direction of the rotating ring 3, the driving screw 11 is rotatably arranged in the strip slide 1-30, the slider 12 is slidably arranged in the strip slide 1-30 and sleeved on the driving screw 11, and the limiter 10 is arranged on the top of the slider 12. When the driving screw 11 rotates, it can drive the slider 12 to move in the strip slide 1-30, thereby changing the distance between the limiter 10 on the top of the slider 12 and the edge skin of the silicon ingot on the base 2.

[0048] The limiter 10 should be arranged on both sides of the width direction of the silicon ingot skin, and whether it is arranged on one side or both sides along the axial direction of the rotating ring 3 can be arranged according to actual needs. The strip-shaped slide groove 1-30 located on the same side of the rotating ring 3 can be set as two corresponding positions, or can be set as one integrally formed. When the latter solution is adopted, the driving screw 11 can be configured as a bidirectional screw, and the forward and reverse threads of the bidirectional screw are respectively located on both sides of the support 2, and are respectively connected to different sliders 12 located on the same side of the rotating ring 3, so that the adjustment efficiency of the limiter 10 can be improved, and by presetting the position of the limiter 10 located on the same side of the rotating ring 3 to be symmetrical about the axis of the rotating ring 3, when adjusting the position of the limiter 10, the center of the silicon ingot skin can be always controlled to be on the axis of the rotating ring 3, which makes it easier to control the tightness of the packaging film on each side of the silicon ingot skin, thereby improving the packaging efficiency and stability.

[0049] The end of the driving screw 11 can be provided with a driving motor 2 8 or a rotating hand wheel extending outside the base 1-10 to facilitate adjustment of the position of the slider 12. The driving motor 1 5 and the driving motor 2 8 can be electrically connected to the controller and control keys in the frame 1 to improve the convenience of operation.

[0050] Compared with the prior art, the beneficial effect of the utility model is that the silicon ingot side skin rapid film wrapping device can avoid the workers from turning over the silicon ingot side skin, reduce the workers' labor intensity, improve the film wrapping efficiency, and reduce the personnel input.

[0051] The above are preferred implementations of the present utility model. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present utility model. These improvements and modifications should also be regarded as the protection scope of the present utility model.
