[0001] This application relates to the field of photovoltaic slicing technology, specifically to an automatic reel-changing device and a slicing machine. Background Technology

[0002] Photovoltaic cells have become a major direction for developing new energy sources due to their advantages such as being pollution-free, not limited by geographical location, and inexhaustible. Photovoltaic cells are made from photovoltaic silicon wafers, and the quality of the silicon wafers significantly affects the working efficiency of the photovoltaic cells. As one of the main pieces of equipment in the silicon wafer cutting field of the photovoltaic industry, the performance of the slicing machine directly affects the production efficiency and cost control of silicon wafers. After the steel wire on the slicing machine's reels is finished being fed, new reels need to be replaced. Replacing the reels requires manual dragging, which is inefficient and may result in the reels falling off during the process, causing safety accidents. Summary of the Invention

In the first position, the support member is engaged with the thread wheel, and in the second position, the support member is separated from the thread wheel.

[0005] In this embodiment, a support member capable of moving to a first position and engaging with the reel is provided. When the reel needs to be replaced, the support member can drive the reel to slide along a first slide rail, thereby moving the reel to a preset replacement position for replacement. After replacement, the support member can drive the reel back to its initial working position. Simultaneously, the support member can also move to a second position, i.e., the support member is separated from the reel. At this point, the support member cannot drive the reel to move, allowing the support member to slide independently along the first slide rail, away from the reel, avoiding interference with the normal operation of the reel, thus completing the reel replacement work. By setting up the support member and the first slide rail, compared to manually dragging the reel in related technologies, work efficiency is significantly improved, and the phenomenon of the reel falling off during replacement is reduced, thereby improving safety during replacement. In addition, by setting up a first drive component, the support member can be driven to move along the thickness direction of the automatic reel changing device, allowing the support member to move to the first or second position, facilitating control of the engagement or disengagement of the support member with the reel.

[0012] In one specific embodiment, the automatic thread-changing wheel device further includes a clamping assembly for clamping a mounting nut on the mounting shaft; the clamping assembly is mounted on the support member, and in the first position, the clamping assembly is flush with the mounting nut, and in the second position, the clamping assembly and the mounting nut have a height difference.

[0013] In one specific embodiment, the automatic thread-changing wheel device further includes a second slide rail disposed on the support member; the clamping assembly is slidably connected to the support member via the second slide rail.

[0014] Secondly, embodiments of this application also provide a slicer, which includes an automatic wire-changing wheel device.

[0015] In this embodiment, the automatic thread-changing device can be installed on the slicing machine.

[0046] Photovoltaic cells have become a major direction for developing new energy sources due to their advantages such as being pollution-free, not limited by geographical location, and inexhaustible. The cells in photovoltaic cells are made from photovoltaic silicon wafers; therefore, the cutting quality of the photovoltaic silicon wafers significantly affects the working performance of the photovoltaic cells. As one of the main pieces of equipment in the field of photovoltaic silicon wafer cutting, the performance of the slicing machine directly affects the production quality and efficiency of the silicon wafers. The slicing machine is equipped with wire reels; after the steel wire on the reel is unloaded, a new reel needs to be replaced. Replacing the reel requires manual dragging, resulting in low replacement efficiency and the possibility of the reel falling off during the replacement process, causing safety accidents.

[0047] To address the aforementioned technical problems, as shown in Figures 1 and 2, this application provides an automatic thread-changing device 12 and a slicer 1 including the automatic thread-changing device 12. The slicer 1 has a thread wheel 11, which can be mounted on the slicer 1 via a mounting shaft 111. The automatic thread-changing device 12 is used to drive the thread wheel 11 to move. The automatic thread-changing device 12 may include: a first slide rail 121, a support member 122, and a first drive assembly 123. The first slide rail 121 is arranged parallel to the mounting shaft 111, the support member 122 is slidably connected to the first slide rail 121, and the first drive assembly 123 is used to drive the support member 122 to move towards or away from the thread wheel 11 along the thickness direction of the automatic thread-changing device 12, so that the support member 122 is located in a first position or a second position. In the first position, the support member 122 is engaged with the thread wheel 11, and in the second position, the support member 122 is separated from the thread wheel 11.

[0048] In this embodiment, by providing a support member 122 that can move to a first position and engage with the reel 11, when the reel 11 needs to be replaced, the support member 122 can drive the reel 11 to slide along the first slide rail 121, thereby moving the reel 11 to a preset replacement position for replacement. After replacement, the support member 122 can drive the reel 11 back to its initial working position. Simultaneously, the support member 122 can also move to a second position, i.e., the support member 122 is separated from the reel 11. At this point, the support member 122 cannot drive the reel 11, allowing the support member 122 to slide independently along the first slide rail 121, away from the reel 11, avoiding interference with the normal operation of the reel 11. This completes the replacement of the reel 11. By providing the support member 122 and the first slide rail 121, compared to manually dragging the reel in related technologies, work efficiency is significantly improved, and the phenomenon of the reel 11 falling off during replacement is reduced, thus improving safety during the replacement process. In addition, by setting the first drive component 123, the support member 122 can be driven to move along the thickness direction of the automatic thread changing device 12, so that the support member 122 can move to the first position or the second position, which facilitates the control of the engagement or disengagement of the support member 122 and the thread wheel 11.

[0049] As shown in Figures 1 and 2, the automatic thread-changing device 12 can be installed on the machine tool of the slicer 1 (not shown in the figures). By setting the automatic thread-changing device 12 in the slicer 1, the automatic replacement of the thread roller 11 can be realized, which can improve work efficiency and save labor costs. It also reduces the possibility of the thread roller 11 falling off during the replacement process, thus improving the safety and reliability of the replacement process.

[0050] In the above embodiments, as shown in Figures 1 to 3, along the length of the automatic thread changing device 12, the thread wheel 11 has two spaced-apart circumferential protrusions 112. The support member 122 may have a groove 122a. In a first position, the circumferential protrusions 112 engage with the groove 122a, and in a second position, the circumferential protrusions 112 separate from the groove 122a.

[0051] In this embodiment, to fix the steel wire, the reel 11 is typically provided with two circumferential protrusions 112 spaced apart. Therefore, a groove 122a is provided on the support member 122. By engaging or disengaging the circumferential protrusions 112 with the groove 122a, the connection or separation of the support member 122 and the reel 11 can be achieved. Specifically, when the first drive assembly 123 drives the support member 122 to move towards the reel 11 along the thickness direction of the automatic reel changing device 12 to the first position, at least a portion of the structure of the circumferential protrusions 112 can extend into the groove 122a. When the support member 122 slides along the first slide rail 121, the sidewall of the circumferential protrusions 112 can abut against the sidewall of the groove 122a, thereby enabling the support member 122 to drive the reel 11 to move along the first slide rail 121. When the first drive assembly 123 drives the support member 122 to move away from the thread wheel 11 along the thickness direction of the automatic thread changing device 12 to the second position, the circumferential protrusion 112 separates from the groove 122a, thereby separating the support member 122 from the thread wheel 11, so that the support member 122 can slide alone along the first slide rail 121.

[0052] In the above embodiments, as shown in Figures 1 to 3, the groove 122a can be arc-shaped.

[0053] In this embodiment, since the spool 11 is provided with a circumferential protrusion 112, and the contact portion between the circumferential protrusion 112 and the groove 122a is an arc-shaped structure, the groove 122a on the support member 122 is also arc-shaped. When the support member 122 is in the first position, both the circumferential protrusion 112 and the groove 122a are arc-shaped structures, which can increase the contact area between the circumferential protrusion 112 and the groove 122a, thereby improving the reliability of their engagement. Furthermore, when the support member 122 drives the spool 11 to slide along the first slide rail 121, the connection reliability between the spool 11 and the support member 122 can be improved, and the stability of the spool 11 when the support member 122 drives it to slide can also be improved, avoiding the phenomenon of falling off during the sliding process and affecting the normal progress of the replacement work.

[0054] In one specific embodiment, as shown in Figures 1 and 2, the automatic thread changing wheel device 12 may also have a second drive assembly 124, which is used to drive the support member 122 to slide along the first slide rail 121.

[0055] In this embodiment, the second drive component 124 can drive the support member 122 to slide along the first slide rail 121. When the support member 122 is in the first position, the second drive component 124 can drive the support member 122 to drive the spool 11 to slide along the first slide rail 121, thereby driving the spool 11 to slide to a preset replacement position. When the support member 122 is in the second position, the second drive component 124 can drive the support member 122 to slide independently along the first slide rail 121 away from the spool 11, avoiding affecting the normal operation of the spool 11. By setting the second drive component 124 to drive the support member 122 to move along the first slide rail 121, manual dragging is not required, which improves the overall replacement efficiency and reduces labor costs.

[0056] In this embodiment, the second drive component 124 can be a linear motor. Linear motors have advantages such as high driving efficiency, high positioning accuracy, and good motion stability, which can further improve the overall replacement efficiency. In other embodiments, the second drive component can also be other drive components. This application does not limit the specific form of the second drive component 124.

[0057] In one specific embodiment, as shown in Figures 2 and 3, the support member 122 may have a recessed portion 122b and an extension portion 122c connected together. A groove 122a is disposed on the recessed portion 122b, and the extension portion 122c is slidably connected to the first slide rail 121 via a second drive assembly 124. Along the thickness direction of the automatic thread-changing wheel device 12, the extension portion 122c, the first slide rail 121, and the first drive assembly 123 are stacked sequentially.

[0058] In this embodiment, the groove 122a is disposed on the recessed portion 122b, so that the groove 122a can be an arc-shaped structure, thereby improving the stability of the support member 122 during the movement of the reel 11. The support member 122 is also provided with an extension portion 122c, which can be connected to the first slide rail 121 via the second drive assembly 124. This allows the second drive assembly 124 to drive the support member 122 to slide along the first slide rail 121 via the extension portion 122c, thereby driving the reel 11 to move along the first slide rail 121 to complete the replacement of the reel 11. Simultaneously, along the thickness direction of the automatic reel changing device 12, the extension portion 122c, the first slide rail 121, and the first drive assembly 123 are stacked sequentially, allowing the first drive assembly 123 to drive the support member 122 to move along the thickness direction of the automatic reel changing device 12 via the extension portion 122c, thereby driving the support member 122 to move to a first position or a second position.

[0059] In one specific embodiment, as shown in Figures 2 and 4, the first drive assembly 123 may include a drive portion 123a and a support portion 123b. The drive portion 123a is capable of driving the support portion 123b to move along the thickness direction of the automatic thread-changing wheel device 12. The support portion 123b is used to abut against the first slide rail 121.

[0060] In this embodiment, the first driving assembly 123 includes a driving part 123a and a supporting part 123b. The driving part 123a can drive the supporting part 123b to move along the thickness direction of the automatic thread changing wheel device 12, and the supporting part 123b abuts against the first slide rail 121, thereby enabling the driving part 123a to drive the first slide rail 121 to move along the thickness direction of the automatic thread changing wheel device 12, and further enabling the supporting member 122, which abuts against the first slide rail 121, to move along the thickness direction of the automatic thread changing wheel device 12, so that the supporting member 122 is in a first position or a second position. At the same time, by providing the supporting part 123b, the contact area between the first driving assembly 123 and the first slide rail 121 can be increased, improving the movement stability when the first driving assembly 123 drives the supporting member 122 to move, and avoiding the supporting member 122 from being unable to properly engage or disengage from the thread changing wheel 11 due to displacement.

[0061] In one specific embodiment, as shown in Figures 1 to 3, along the length of the automatic thread-changing reel device 12, both ends of the first slide rail 121 can be provided with a first drive assembly 123, and at least four first drive assemblies 123 and two first slide rails 121 can be symmetrically arranged on both sides of the reel 11. Meanwhile, two extension portions 122c can be correspondingly connected to both ends of the recess 122b.

[0062] In this embodiment, both ends of the first slide rail 121 can be provided with a first drive component 123, which not only supports the first slide rail 121 but also improves the stability of the first drive component 123 driving the first slide rail 121 during movement, preventing the first slide rail 121 from deflecting and causing the support member 122 to shift. Simultaneously, two extensions 122c can be symmetrically provided at both ends of the recess 122b. Along the thickness direction of the automatic thread changing wheel device 12, the bottom of the two extensions 122c is provided with the first slide rail 121 and the first drive component 123. By providing the first slide rail 121 and the first drive component 123 at both ends of the support member 122, the support effect of the support member 122 on the thread wheel 11 can be further improved, and the stability of the support member 122 driving the thread wheel 11 to slide can be further improved, preventing the thread wheel 11 from falling off during sliding.

[0063] In one specific embodiment, as shown in Figures 2 and 5, the automatic reel changer device 12 may further include a clamping assembly 125 for clamping the mounting nut 113 on the mounting shaft 111. The clamping assembly 125 may be mounted on the support member 122. In a first position, the clamping assembly 125 is flush with the mounting nut 113, and in a second position, the clamping assembly 125 and the mounting nut 113 have a height difference.

[0064] In this embodiment, the thread wheel 11 is sleeved on the mounting shaft 111 of the slicer 1 and fixed by components such as the mounting nut 113. When replacing the thread wheel 11, the mounting nut 113 must be removed first. By providing a clamping component 125 on the automatic thread wheel changing device 12, the clamping component 125 can clamp and remove the mounting nut 113. Specifically, the clamping component 125 can be installed on the support member 122. When the support member 122 moves to the first position, the clamping component 125 is flush with the mounting nut 113. The clamping component 125 can clamp and remove the mounting nut 113 to release the fixed connection between the thread wheel 11 and the mounting shaft 111, thereby allowing the support member 122 to drive the thread wheel 11 to slide along the first slide rail 121.

[0065] In the above embodiments, the clamping assembly 125 may include a clamping member 125a and a reduction motor 125b connected to each other. When the support member 122 is in the first position, the clamping member 125a can clamp the mounting nut 113, and at the same time, the reduction motor 125b can drive the clamping member 125a to rotate, thereby disassembling the mounting nut 113.

[0066] In one specific embodiment, as shown in Figures 1 and 5, the automatic thread-changing wheel device 12 may further include a second slide rail 126, which is disposed on the support member 122. The clamping assembly 125 is slidably connected to the support member 122 via the second slide rail 126.

[0067] In this embodiment, the clamping assembly 125 can be slidably connected to the support member 122 via the second slide rail 126, so that the clamping assembly 125 can slide along the second slide rail 126, thereby adjusting its positional relationship with the mounting nut 113, so that the clamping assembly 125 can disassemble the mounting nut 113.

[0068] In the above embodiments, the automatic thread changing device 12 may also be provided with a control module, which can control the first drive component 123, the second drive component 124 and the clamping component 125 to work or stop working, so as to realize the automated operation of the automatic thread changing device 12.

[0069] The control module can be a programmable logic controller (PLC). In other embodiments, the control module can also be in other forms. The specific form of the control module is not limited in the embodiments of this application.

[0070] In the above embodiments, the automatic thread changing device 12 may also be equipped with a first position sensor and a second position sensor (not shown in the figure). The first position sensor may be installed at the end of the first slide rail 121 to detect the real-time position of the support member 122 as it slides along the first slide rail 121, and transmit the generated detection result to the control module, thereby determining whether the support member 122 has driven the thread wheel 11 to move to the preset changing position. The second position sensor may be installed on the support portion 123b of the first drive assembly 123 to detect the movement distance of the support portion 123b, and transmit the generated detection result to the control module, thereby enabling the control module to drive the support member 122 to move to the first position or the second position by controlling the first drive assembly 123.

[0071] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
