[0002] The edge skin is the silicon material with one curved surface and one flat surface left after the cylindrical single crystal silicon rod is squared. Figure 1 and Figure 2 As shown in the figure. Since the price of single crystal silicon rods is very expensive, the industry has an increasing demand for recycling the edge skin to improve the utilization rate of single crystal silicon rods. There are usually two ways to cut the edge skin to get square rods: Figure 1 As shown, one method is to first cut off the arc top 62 of the edge skin, and then cut off the corners 63 on both sides of the edge skin; Figure 2 As shown, another method is to first cut off the corners 63 on both sides of the edge skin, and then cut off the arc top 62 of the edge skin to obtain a square rod 61.

[0003] In the current equipment for cutting edge skins, the loading device can carry at most two pieces of edge skins, and the cutting device can cut at most two pieces of edge skins at the same time, which is inefficient. In addition, the equipment is large in size and occupies a large space. In the cutting process, loading, cutting, and unloading are carried out in sequence. During the loading and unloading process, the cutting device returns to the initial position to wait, which takes a long time and greatly affects the production rhythm. Summary of the invention

[0044] In order to make the technical solutions and advantages in the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0045] The present embodiment provides an edge skin cutting device, which is used to cut the edge skin through a cutting line. The arc top of the edge skin can be cut off, and the corner of the edge skin can also be cut off. The present embodiment only takes the cutting of the arc top of the edge skin as an example for explanation. Those skilled in the art can directly apply the solution provided by the present embodiment to the cutting of the corners; they can also make equivalent changes or replacements to the relevant technical features of the technical solution provided by the present embodiment and apply them to the cutting of the corners. The technical solutions after these changes or replacements will fall within the protection scope of this application.

[0046] The edge skin cutting equipment provided in this embodiment can be adapted to the edge skin obtained by cutting workpieces made of hard and brittle materials such as photovoltaic silicon (single crystal silicon rods, polycrystalline silicon ingots), quartz crystals, silicon carbide, semiconductors, silicon nitride, sapphire, magnetic materials, ceramics, and cemented carbide. The cutting wire can be a thin wire coated with diamond abrasive particles.

[0047] like Figure 3 and Figure 4 As shown, this embodiment provides a skin edge cutting device, including: a loading device 1 and a cutting device 2. The loading device 1 has a first group of stations 101 and a second group of stations 102 arranged side by side, and each group of stations is provided with at least two vertically arranged cutting stations 113. Specifically, the first group of stations 101 includes at least two cutting stations 113 arranged up and down, and the second group of stations 102 also includes at least two cutting stations 113 arranged up and down, and the first group of stations 101 and the second group of stations 102 are arranged side by side left and right. Each cutting station 113 can hold a piece of skin edge to be cut.

[0048] The cutting device 2 is used to synchronously cut the edge skins of each cutting station 113 in the first group of stations 101, or to synchronously cut the edge skins of each cutting station 113 in the second group of stations 102. In other words, the cutting device 2 can synchronously cut the edge skins on all cutting stations 113 in the first group of stations 101 on the left, and during this process, the second group of stations 102 on the right can perform loading and unloading operations.

[0049] When the first group of stations 101 has finished cutting and the second group of stations 102 has finished loading, the cutting device 2 then synchronously cuts the edge skins of each cutting station 113 in the second group of stations 102. During this process, the first group of stations 101 performs unloading and loading operations.

[0050] The technical solution provided in this embodiment adopts a loading device, having a first group of workstations and a second group of workstations arranged side by side, each group of workstations is provided with at least two vertically arranged cutting stations; each cutting station is used to place a piece of edge skin to be cut; the cutting device is used to synchronously cut each cutting station in the first group of workstations, or synchronously cut each cutting station in the second group of workstations, so that the cutting device can cut at least two pieces of edge skin at a time, and in the process of cutting one group of workstations, the other group of workstations performs loading and unloading operations. After loading and unloading are completed, the cutting device directly moves to the other group of workstations for cutting, thus realizing continuous cutting without waiting for loading and unloading, which is beneficial to improving the stability of the production rhythm and can improve production efficiency.

[0051] On the basis of the above technical solution, this embodiment provides an implementation method of a loading device 1:

[0052] like Figures 4 to 8 As shown, the loading device 1 includes: the loading device 1 includes a loading frame, a first tightening mechanism 12 and a second tightening mechanism 13 .

[0053] The loading frame 1 is provided with at least four cutting stations 113, and the cutting stations 113 arranged up and down constitute the first group of stations or the second group of stations. The first tightening mechanism 12 is located in the cutting station 113, and is used to tighten the two ends of the edge skin 6 to be cut to form a square rod 61. The second tightening mechanism 13 is located in the cutting station 113, and is used to tighten the two ends of the remaining part of the edge skin 6 after cutting. The remaining part after cutting can be the arc top 62 or the corner 63. This embodiment takes the arc top 62 as an example for description.

[0054] The loading device and cutting device provided in the embodiment of the present application can cooperate to achieve cutting of two or more edge skins at one time; when applied to edge skin cutting equipment, the efficiency of edge skin cutting can be improved.

[0055] Furthermore, the cutting stations can be divided into two groups, and the two groups of cutting stations are arranged side by side, and each cutting station in one group cuts synchronously. When one group of cutting stations is cutting, the other group of cutting stations can load and unload materials. After one group of cutting stations has finished cutting, the other group of cutting stations can immediately cut, and the cutting device can cut continuously. There is no need to wait for loading and unloading, and cutting is carried out continuously, which can adapt to the production rhythm and improve production efficiency.

[0056] like Figure 5 and Figure 6 As shown, specifically, in the loading device provided by the embodiment of the present application, the edge skin 6 is cut to obtain the arc top 62 and the square rod 6. The first tightening mechanism 12 is used to tighten the square rod 61; the second tightening mechanism 13 is arranged above the first tightening mechanism 13, and is used to tighten the arc top 62.

[0057] like Figure 4 and Figure 5 As shown, based on the above technical solution, the present application provides a specific implementation of a loading frame, the loading frame includes a loading frame column 111 and a loading frame plate 112. The number of the loading frame columns 111 is at least two, erected on the ground.

[0058] The loading frame plates 112 are connected between the loading frame columns 111 in the horizontal direction. A plurality of loading frame plates 112 are arranged at intervals, and the space formed between two adjacent loading frame plates 112 serves as a cutting station 113. It is worth noting that the number of the loading frame plates 112 can be two, three, four or more than four; specifically, a corresponding number of loading frame plates 112 can be arranged according to needs.

[0059] like Figure 4 As shown, in order to further improve production efficiency, in the loading device provided in the embodiment of the present application, the space formed between two adjacent loading frame plates 112 has two cutting stations 113, and the cutting stations 113 arranged up and down on one side thereof cut synchronously. Figure 4 In the embodiment, a total of 12 cutting stations are formed by the loading frame plate 112, of which 6 cutting stations are arranged up and down along the left side, and these 6 stations cut synchronously. The other 6 cutting stations are arranged up and down along the right side, and cut synchronously. When the cutting station on the left side is cutting, the cutting station on the right side can load and unload materials. When the cutting on the left side is completed, the cutting device can immediately cut the right side, so that the cutting process can be carried out continuously, which solves the problem of the traditional solution that cutting can only be carried out after the loading and unloading are completed, and can multiply the cutting efficiency.

[0060] like Figure 5 As shown, as a specific implementation, the first tightening mechanism 12 is disposed on the upper surface of the loading frame plate 112 , and the second tightening mechanism 13 is disposed on the lower surface of the loading frame plate 112 .

[0061] like Figure 7 As shown, on the basis of the above technical solution, this embodiment provides a specific implementation of the first tightening mechanism, and the first tightening mechanism 12 includes a first fixed tightening member 121 and a first movable tightening member 122. The first fixed tightening member 121 is fixed on the loading frame. The first movable tightening member 122 is arranged on the loading frame, and the first movable tightening member 122 can be away from or close to the first fixed tightening member 121. Specifically, the first fixed tightening member 121 and the first movable tightening member 122 are respectively located at the two ends of the edge skin to be cut to form the square rod 61. The first movable tightening member 122 moves toward the first fixed tightening member 121 until the first fixed tightening member 121 tightens the edge skin from both ends.

[0062] On the basis of the above technical solution, in the loading device provided in the embodiment of the present application, the first movable tightening member 122 includes a first tightening seat 1221, a first tightening driving member 1222 and a first tightening head 1223. Specifically, the first tightening seat 1221 is fixed on the loading frame, and the first tightening driving member 1222 is arranged on the first tightening seat 1221. The first tightening head 1223 is arranged at the end of the first tightening driving member 1222, and the first tightening driving member 1222 drives the first tightening head 1223 to move in a direction away from or close to the first fixed tightening member 121. The first tightening driving member 1222 can be a driving mechanism such as a cylinder, a hydraulic cylinder or a motor.

[0063] It is worth noting that the first tightening head 1223 is in direct contact with the edge skin when tightening the edge skin. To prevent contamination and damage to the edge skin, the first tightening head 1223 can be made of an elastic material, such as rubber, silicone or felt.

[0064] Specifically, the loading device provided in the embodiment of the present application also includes a skin pad 14. The skin pad 14 is arranged on the loading frame to support the skin 6. It is understandable that the skin pad 14 can also adopt other structures that can support the skin 6, such as the loading frame is provided with fixed blocks, and the fixed blocks form a space for supporting the skin. In this embodiment, two skin pads 14 are used, which are arranged at intervals in a cutting station to support a piece of skin 6.

[0065] like Figure 5 , Figure 6 and Figure 8 As shown, in the material loading device provided in the embodiment of the present application, the second tightening mechanism 13 includes two second movable tightening members. The two second movable tightening members are arranged on the material loading frame at intervals and can move relative to the material loading frame to adjust the distance between the two.

[0066] In a specific implementation, the second movable tensioning member includes a second tensioning seat 131, a second tensioning driving member 132 and a second tensioning head 133. The second tensioning seat 131 is fixed on the material loading frame, the second tensioning driving member 132 is disposed on the second tensioning seat 131, and the second tensioning head 133 is disposed at the end of the second tensioning driving member 132. The second tensioning driving member 132 drives the second tensioning head 133 to move downward in a direction away from or close to another second movable tensioning member.

[0067] It is understandable that the second tightening head 133 can be made of the same elastic material as the first tightening head 1223. The two second movable tightening members are arranged at intervals on the loading frame to fix the arc top portion 62 of the edge skin to be cut.

[0068] In the above solution, the tightening members for fixing the arc top portion 62 are all movable and can adapt to the position drift of the arc top portion 62 relative to the square rod 61 .

[0069] On the basis of the above technical solution, this embodiment provides an implementation method of a cutting device 2:

[0070] like Figures 9 to 18 As shown, the cutting device includes: a cutting frame 21, a cutting mechanism and a cutting frame body 241. The cutting frame body 241 can move relative to the cutting frame 21 along the feeding direction. The cutting mechanism is arranged on the cutting frame body and can move relative to the cutting frame body along the vertical direction. The cutting mechanism includes at least two sets of cutting wheel assemblies arranged side by side, and one set of cutting wheel assemblies is used to cut the edge skin 6 in a cutting station. The vertical movement amplitude of the cutting mechanism is less than the height of a cutting station.

[0071] The cutting device provided in the embodiment of the present application has a cutting mechanism including at least two sets of cutting wheel assemblies arranged side by side, one set of cutting wheel assemblies is used to cut a piece of edge skin. The structure is reasonably arranged, the space utilization rate is high; and multiple pieces of edge skin can be cut at the same time, and the cutting efficiency is high.

[0072] It is worth noting that the number of cutting wheel assemblies can be set to two groups, three groups, four groups or more groups; the specific number of cutting assemblies is set according to the process requirements.

[0073] Furthermore, at least two groups of cutting wheel assemblies are arranged in a vertical interval, and the feeding direction is a horizontal direction.

[0074] On the basis of the above technical solution, the cutting device provided in the embodiment of the present application further includes a cutting lifting mechanism. The cutting lifting mechanism is connected to the cutting wheel assembly and is used to drive each cutting wheel assembly to rise and fall. After a group of edge skins are cut, the height of the cutting wheel assembly is adjusted by the cutting lifting mechanism and then moved horizontally to avoid surrounding components, so that the cutting line wound on the cutting wheel assembly can avoid surrounding components and move horizontally. After moving into position, the height of the cutting wheel assembly is adjusted by the cutting lifting mechanism, and the edge skin is cut by the cutting line after reaching the cutting position.

[0075] On the basis of the above technical solution, the present application provides a specific implementation of a cutting wheel assembly, the cutting wheel assembly includes a driving wheel assembly 22 and a driven wheel assembly 23. The driving wheel assembly 22 in each cutting wheel assembly is arranged on an active lifting frame 242 along a vertical interval, and the active lifting frame 242 is arranged on the cutting frame body and can move vertically relative to the cutting frame body. The driven wheel assembly 23 in each cutting wheel assembly is arranged on a driven lifting frame 243 along a vertical interval, and the driven lifting frame 243 is arranged on the cutting frame body and can move vertically relative to the cutting frame body. Fig. 9Taking the illustrated solution as an example, six groups of cutting wheel assemblies are arranged vertically, the driving wheel assemblies 22 in the six groups are arranged in a row along the left side, and the driven wheel assemblies 23 are arranged in a row along the right side.

[0076] Specifically, a guide mechanism is provided between the active lifting frame 242 and the cutting frame body 241, and the active lifting frame 242 moves vertically relative to the cutting frame body 241 through the guide mechanism; a guide mechanism is provided between the driven lifting frame 243 and the cutting frame body 241, and the driven lifting frame 243 moves vertically relative to the cutting frame body 241 through the guide mechanism.

[0077] The present application provides a specific implementation of a guide mechanism, which includes a wire wheel lifting rail 251 and a wire wheel lifting slider 252; the wire wheel lifting rail 251 is arranged on the cutting frame 241 and extends in the vertical direction; the wire wheel lifting slider 252 is arranged on the active lifting frame 242 and is slidably matched with the wire wheel lifting rail 251; the active lifting frame 242 moves relative to the cutting frame 241 through the slide rail and slider structure. It can be understood that the driven lifting frame 243 and the cutting frame 241 are also respectively provided with a wire wheel lifting rail 251 that is slidably matched and other structures of the wire wheel with a guiding function, such as a guide rod guide sleeve structure, a slider slide groove structure, etc.

[0078] One step, such as Figure 4 As shown, in the cutting device provided in the embodiment of the present application, a wire wheel lifting drive motor 261 is further provided, which is used to provide a driving force for the active lifting frame 242 and the driven lifting frame 243 to move relative to the cutting frame 21. Specifically, the active wheel assembly 22 and the driven wheel assembly 23 are driven up and down by the corresponding wire wheel lifting drive motors 261, one wire wheel lifting drive motor 261 is specifically connected to the active lifting frame 242 to drive the active lifting frame 242 to move up and down, and the other wire wheel lifting drive motor 261 is connected to the driven lifting frame 243 to drive the driven lifting frame 243 to move up and down.

[0079] One implementation method is: the wire wheel lifting drive motor 261 is connected to the lead screw to drive the lead screw to rotate, so that the nut matched with the lead screw thread moves up and down, and the nut is connected to the active lifting frame 242 and the driven lifting frame 243.

[0080] It is worth noting that the wire wheel lifting drive motor 261 can also adopt other drive structures that can provide driving force.

[0081] Furthermore, in the cutting device provided in the embodiment of the present application, a cutting feed motor 262 is also provided to drive the cutting frame 241 to move relative to the cutting frame 21 along the feeding direction, and the output end of the cutting feed motor 262 is connected to the cutting feed lead screw 253, and the cutting feed lead screw 253 is provided on the cutting frame 21. A nut is provided on the cutting frame 241, and the nut is sleeved on the cutting feed lead screw 253. The cutting feed motor 262 drives the cutting feed lead screw 253 to rotate, so as to realize the cutting frame 241 connected to the nut to move relative to the cutting frame 21 along the feeding direction. It is worth noting that the cutting feed motor 262 can be replaced by other structures that can provide driving force; the lead screw and nut structure can also be replaced by other existing structures that transmit power.

[0082] On the basis of the above scheme, in the cutting device of the embodiment of the present application, the active lifting frame 242 and the driven lifting frame 243 are lifted and lowered synchronously so that the driving wheel assembly 22 and the driven wheel assembly 23 are at the same height; the annular cutting line 9 wound between the driving wheel assembly 22 and the driven wheel assembly 23 extends in the horizontal direction.

[0083] Based on the above scheme, the present application provides a specific implementation of a driving wheel assembly, wherein the driving wheel assembly 22 includes a driving wire wheel 221 and a wire wheel motor 222. The driving wire wheel 221 is rotatably arranged on an active lifting frame 242, and the wire wheel motor 222 is arranged on the active lifting frame 242 to drive the driving wire wheel 221 to rotate.

[0084] Specifically, the wire wheel motor 222 is connected to the driving wire wheel 221 through a wire wheel transmission belt 223. It is understandable that the wire wheel motor 222 and the driving wire wheel 221 can also be connected by other transmission members, for example, a chain.

[0085] In the cutting device provided in the embodiment of the present application, the driving wheel assembly 22 further includes a spraying mechanism 27; the spraying mechanism 27 is disposed on the driving wheel bracket and is used to spray cutting fluid to the cutting area where the cutting line is located.

[0086] In the cutting device provided in the embodiment of the application, the driven wheel assembly 23 is also provided with a spray mechanism 27, which is arranged on the driven wheel bracket and is used to spray cutting liquid to the cutting area where the cutting line is located. In the specific implementation, the spray mechanism 27 sprays during the spraying process, and is used to spray cutting liquid on the edge skin and the cutting seam formed by the cutting edge skin of the annular cutting line. On the one hand, it can cool the annular cutting line to prevent the high temperature from affecting the cutting surface quality; on the other hand, it can wash away the silicon powder attached to the cutting line to reduce the wear on the cutting surface.

[0087] In the cutting device provided in the embodiment of the present application, the driving wheel assembly 22 and the driven wheel assembly 23 also include a cleaning mechanism 28, which is mainly used to clean some stop components, detection components, etc. to prevent excessive silicon powder from adhering thereto and affecting the execution effect.

[0088] Furthermore, the driven wheel assembly 23 includes a driven line wheel 231 and a counterweight assembly 232. The driven line wheel 231 is disposed on the driven lifting frame 243, and the counterweight assembly 232 is connected to the driven line wheel 231 to adjust the angle of the driven line wheel 231. During the cutting process, the pulling force provided by the counterweight assembly 232 to the driven line wheel 231 can make the cutting line have a certain tension to meet the cutting requirements.

[0089] Based on the above solution, this embodiment also provides a cutting control method, which can be applied to the above edge skin cutting device. The cutting control method includes:

[0090] Step 1: When the first group of workstations completes loading, the cutting mechanism in the cutting device is controlled to move to the first group of workstations, and the first group of workstations is cut after moving into position.

[0091] Step 2: When the first group of stations completes cutting and the second group of stations completes loading, the cutting mechanism is controlled to move upward a preset distance, and then moves to the second group of stations, and cuts the second group of stations after moving into position; the preset distance is less than the height of a cutting station.

[0092] For the above scheme, Fig.19 As shown, the cutting stations arranged up and down on the left side are regarded as the first group of stations, and the cutting stations arranged up and down on the right side are regarded as the second group of stations. When the first group of stations completes loading, the cutting mechanism in the cutting device 2 is controlled to move along the feeding direction, and after moving into position, each cutting station in the first group of stations is synchronously cut. The direction of cutting the first group of stations is specifically to cut the first group of stations along a first direction, where the first direction is the direction from the first group of stations toward the second group of stations, specifically Fig.19 Feed cutting from left to right.

[0093] Fig. 20 The cutting device 2 has finished cutting the first group of stations and has reached the position between the two groups of stations. When the second group of stations has finished loading, the second group of stations can be cut. Control the cutting mechanism to move to the second group of stations, and cut the second group of stations after it moves into place, specifically including: controlling the cutting mechanism to move along the first direction to the side of the second group of stations away from the first group of stations; after moving into place, controlling the cutting mechanism to move downward a preset distance; controlling the cutting mechanism to cut the second group of stations along the second direction, the second direction being opposite to the first direction, that is, Fig.19 Therefore, the cutting mechanism needs to be moved to the right side of the second group of stations. Fig.21As shown in the figure, the height of the cutting line is at the cutting surface between the square bar and the top of the arc. If the cutting mechanism is moved directly to the right, it will be affected by the second group of station edge skins. Therefore, it is necessary to control the cutting mechanism to move upward by a preset distance so that the cutting line is higher than the top of the edge skin (such as Fig. 22 ), then move the cutting mechanism to the right side of the second group of stations, and then control the cutting mechanism to descend a preset distance to cut the second group of stations from right to left. The preset distance is less than the height of a cutting station.

[0094] In the above-mentioned cutting process, after the first group of stations has finished cutting, the cutting mechanism is first moved to a position away from the first group of stations to cut the second group of stations. During the cutting process of the second group of stations, the first group of stations can be loaded and unloaded. The distance between the loading and unloading clamping device and the cutting mechanism is relatively far, and interference is not easy to occur. The cutting mechanism and the loading and unloading clamping device can be protected, so that the cutting process can proceed smoothly. In addition, the interference problem between the edge skin and the cutting line can be solved by coordinating the up and down movement of the cutting mechanism.

[0095] Fig.23 The second group of stations is shown to be cutting. When the second group of stations completes cutting, the cutting mechanism is controlled to move upward by a preset distance so that the cutting line is higher than the edge skin, and then the cutting mechanism is controlled to move along the second direction to the side of the first group of stations away from the second group of stations, that is, to the left side of the first group of stations.

[0096] After the cutting mechanism is controlled to move along the first direction to the side of the second group of workstations away from the first group of workstations and move to the position, the method further includes: controlling the second tightening mechanism to tighten the arc top of the edge skin, the second tightening mechanism being located above the first tightening mechanism. And controlling the first tightening mechanism to tighten the square rod part of the edge skin. After tightening, the second group of workstations is started to cut.

[0097] A detection device is also provided in each cutting station of the loading device 1 for detecting the position of the cutting mechanism and controlling the movement of the cutting mechanism accordingly.
