[0001] The utility model relates to the technical field of wire cutting, in particular to a cutting assembly, a wire cutting machine and a wire cutting machine set. Background Art

[0002] Wire cutting is a processing method in which a cutting wire reciprocates at a high speed and moves relative to a workpiece to be cut (such as materials like photovoltaic silicon rods, semiconductors, silicon carbide, sapphire, magnetic materials, etc.), so that the cutting wire cuts the workpiece to be cut.

[0003] The equipment for realizing wire cutting is a wire cutting machine. Existing wire cutting machines usually have a loading and unloading port opened at one end of the cutting assembly, and the loading and unloading operations of the workpiece to be cut are realized through this loading and unloading port. However, for different workshops, the internal space layout is different, and the requirements for the placement of equipment are also different. The current way of only setting one loading and unloading port on the wire cutting machine will undoubtedly limit the placement of the equipment, is not conducive to the utilization of the workshop space, and reduces the applicable range of the wire cutting machine.

[0004] Correspondingly, the art needs a new technical solution to solve the above problems. Summary of the Utility Model

The applicable breadth of the cutting assembly is improved, the placement of the wire cutting machine is made more flexible, which is conducive to improving the space utilization rate of the workshop, and provides a basis for the transformation of automatic loading and unloading.

[0010] In a preferred technical solution of the above cutting assembly, the projections of the first loading and unloading port and the second loading and unloading port on the axial direction of the main roller assembly coincide.

[0014] Through the above setting method, by setting the third loading and unloading port and the fourth loading and unloading port, the convenience of loading and unloading can be further improved, making the layout form of the wire cutting machine more flexible and more applicable.

[0015] In the preferred technical solution of the above cutting assembly, the opening areas of the third loading and unloading port and the fourth loading and unloading port are larger than the opening areas of the first loading and unloading port and the second loading and unloading port.

[0041] The preferred embodiments of the present application will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present application and are not intended to limit the protection scope of the present application. For example, although this embodiment is introduced in combination with a wire cutting machine as a slicing machine, this is not intended to limit the protection scope of the present application. Without departing from the principle of the present application, those skilled in the art can apply the present application to other application scenarios. For example, the present application can also be applied to a mortar machine, etc.

In addition, the terms "first", "second", "third", "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in the description of the present application, "a plurality of" means at least two.

[0043] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and defined, the terms "installation", "connection", and "linkage" 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 direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0044] First, refer to Figure 1 and Figure 2 , and introduce the wire cutting machine of this application.

[0045] As Figure 1 shown, in order to solve the problem of poor applicability of the existing wire cutting machine, the cutting assembly 1 of this application includes a cutting frame 11 and a main roller assembly 12. The main roller assembly 12 is installed on the cutting frame 11, and the cutting wire is wound between the main roller assemblies 12 to form a wire mesh. A first loading and unloading port 111 and a second loading and unloading port 112 are provided on the cutting frame 11. The first loading and unloading port 111 and the second loading and unloading port 112 are arranged on two opposite side walls of the cutting frame 11 along the axial direction of the main roller assembly 12.

[0046] When the cutting assembly 1 is applied to the wire cutting machine 100, either the first loading and unloading port 111 or the second loading and unloading port 112 can be selected for the loading operation. After cutting, either the first loading and unloading port 111 or the second loading and unloading port 112 can be used for the unloading operation.

[0047] By providing the first loading and unloading port 111 and the second loading and unloading port 112 on two opposite side walls of the cutting frame 11 arranged along the axial direction of the main roller assembly 12, various loading and unloading methods can be realized. For example, four methods of front-up front-down, back-up back-down, front-up back-down, and back-up front-down can be realized (taking the first loading and unloading port 111 as the front and the second loading and unloading port 112 as the back), which improves the applicable breadth of the cutting assembly 1, makes the placement of the wire cutting machine 100 more flexible, is beneficial to improving the space utilization rate of the workshop, and provides a basis for the transformation of automatic loading and unloading.

[0048] Next, in combination with Figure 1 and Figure 2 , introduce the preferred implementation manner of the cutting assembly 1 of this application.

[0049] As Figure 1 and Figure 2As shown, in a preferred embodiment, the cutting assembly 1 includes a cutting frame 11 and three main roller assemblies 12 disposed on the cutting frame 11. The three main roller assemblies 12 are arranged in an inverted triangle. The two ends of each main roller assembly 12 are respectively installed on two opposite side walls of the cutting frame 11. The cutting wire winds around the three main roller assemblies 12 to form a wire mesh. The wire mesh between the two upper main roller assemblies 12 is used to cut the workpiece to be cut 7. The cutting frame 11 is provided with a first loading and unloading opening 111, a second loading and unloading opening 112, a third loading and unloading opening 113, and a fourth loading and unloading opening 114. The first loading and unloading opening 111 and the second loading and unloading opening 112 are respectively opened on the two side walls where the main roller assemblies 12 are installed. The projections of the first loading and unloading opening 111 and the second loading and unloading opening 112 in the axial direction of the main roller assembly 12 coincide, and the first loading and unloading opening 111 and the second loading and unloading opening 112 are disposed above the main roller assembly 12. The third loading and unloading opening 113 and the fourth loading and unloading opening 114 are disposed on the other two opposite side walls of the cutting frame 11 along the radial direction of the main roller assembly 12, and the opening areas of the third loading and unloading opening 113 and the fourth loading and unloading opening 114 are larger than the opening areas of the first loading and unloading opening 111 and the second loading and unloading opening 112.

[0050] In this way, by providing four loading and unloading openings, one or several of the four loading and unloading openings can be selected for loading and unloading according to the specific layout position of the wire cutting machine 100. No matter how the wire cutting machine 100 is placed, there will be no problem of inability to load and unload. Since the projections of the first loading and unloading opening 111 and the second loading and unloading opening 112 in the axial direction of the main roller coincide, it is beneficial to the unified operation of loading and unloading, improves the loading and unloading efficiency, and avoids loading and unloading errors caused by different loading and unloading heights. By providing the third loading and unloading opening 113 and the fourth loading and unloading opening 114, the convenience of loading and unloading can be further improved, making the layout form of the wire cutting machine 100 more flexible and more applicable. Since the opening areas of the third loading and unloading opening 113 and the fourth loading and unloading opening 114 are larger than the opening areas of the first loading and unloading opening 111 and the second loading and unloading opening 112, it is beneficial to improve the convenience of maintenance of the main roller assembly 12 and other components inside the cutting frame 11.

[0051] Of course, the above setting method is only preferred. Those skilled in the art can adjust it as long as the adjusted technical solution does not deviate from the principle of this application.

[0052] For example, although the above embodiment is introduced by taking the coincidence of the projections of the first loading and unloading opening 111 and the second loading and unloading opening 112 in the axial direction of the main roller assembly 12 as an example, the corresponding relationship between the first loading and unloading opening 111 and the second loading and unloading opening 112 is not limited to this. Those skilled in the art can adjust it, such as adjusting the center heights of the two to be equal but the contours do not coincide, or adjusting the contours of the two to coincide but the center heights are not equal.

[0053] For another example, although the above-described embodiments are described by taking the first loading and unloading port 111 and the second loading and unloading port 112 being located above the main roller assembly 12 as an example, this is only exemplary, and those skilled in the art can adjust it based on specific requirements. For example, the first loading and unloading port 111 and the second loading and unloading port 112 can be arranged below the main roller assembly 12. At this time, the wire mesh on the lower side of the main roller assembly 12 is used for cutting the workpiece to be cut 7.

[0054] For another example, although the above-described embodiments are described in combination with the third loading and unloading port 113 and the fourth loading and unloading port 114 being provided, the third loading and unloading port 113 and the fourth loading and unloading port 114 are not necessary, and those skilled in the art can choose whether to provide them according to requirements. For example, neither of them can be provided or only one of them can be provided.

[0055] For another example. The areas of the third loading and unloading port 113 and the fourth loading and unloading port 114 are not necessarily larger than those of the first loading and unloading port 111 and the second loading and unloading port 112, and those skilled in the art can flexibly set their areas.

[0056] Continue to refer below Figure 1 、 Figure 2 、 Figure 4 and Figure 5 to introduce the wire cutting machine of the present application.

[0057] As Figure 1 、 Figure 2 、 Figure 4 and Figure 5 shown, the present application also provides a wire cutting machine 100, and the wire cutting machine 100 includes the cutting assembly 1 according to any one of the above first aspects.

[0058] By adopting the above cutting assembly 1 on the wire cutting machine 100, the wire cutting machine 100 can achieve various loading and unloading methods, can improve the placement flexibility and applicability of the wire cutting machine 100, and further improve the space utilization rate of the workshop, providing favorable conditions for the transformation of the automated workshop.

[0059] See Figure 1 and Figure 2 , in a specific embodiment, the wire cutting machine 100 is a slicing machine, and the slicing machine includes a cutting assembly 1, a feeding assembly 2, a wire winding chamber assembly 3, an electric control cabinet 4, a liquid path system 5 and a gas path system 6.

[0060] The cutting assembly 1 includes a cutting frame 11 and a main roller assembly 12. The first loading and unloading port 111, the second loading and unloading port 112, the third loading and unloading port 113 and the fourth loading and unloading port 114 are arranged on the four side walls of the cutting frame 11, and the specific arrangement method is as described above and will not be elaborated here.

[0061] The feeding assembly 2 is arranged on the upper side of the cutting frame 11, and the feeding assembly 2 is connected to the cutting frame 11 in a liftable manner. The bottom of the feeding assembly 2 is used to mount the workpiece to be cut 7 and can drive the workpiece to be cut 7 to feed towards the main roller assembly 12. During the cutting process, the feeding assembly 2 makes a vertical feed, so that the workpiece to be cut 7 is cut by the wire mesh. The specific structure and setting method of the feeding assembly 2 are conventional technologies in the art and will not be elaborated herein.

[0062] The wire winding chamber assembly 3 is arranged on the lower side of the cutting frame 11, and a cavity is arranged in the lower part of the cutting frame 11. The wire winding chamber assembly 3 includes a wire winding component (such as a wire pay-off and take-up roller) and a wire arranging component (a wire arranging wheel, a tension wheel, a steering wheel), etc. The wire winding component is arranged in the cavity. Usually, two sets of the above components are provided, one set is used to pay out the cutting wire during the cutting process, and the other set is used to recover the cutting wire during the cutting process. The specific wire pay-off and take-up principle is a conventional means in the art and will not be elaborated in this application.

[0063] By arranging the wire winding chamber assembly 3 on the lower side of the cutting frame 11, it is beneficial to realize the compact structure of the wire cutting machine 100, thereby reducing the floor area of the wire cutting machine 100 and being beneficial to improving the layout flexibility of the wire cutting machine 100.

[0064] The electric control cabinet 4 is used to control the actions of each component of the wire cutting machine 100. It is arranged on the side wall where the second loading and unloading opening 112 is located, and the bottom of the electric control cabinet 4 is higher than the second loading and unloading opening 112.

[0065] The liquid path system 5 of the wire cutting machine 100 includes a pipeline component 51 and a liquid supply cylinder 52. The cutting fluid discharged from the liquid supply cylinder 52 is mainly supplied to the cutting frame 11 through the pipeline component 51 to spray lubricate and cool the cutting wire and the workpiece to be cut 7. After that, the waste liquid is recycled and returned to the liquid supply cylinder 52 again to form a cycle. Among them, the pipeline component 51 and the liquid supply cylinder 52 are arranged side by side along the radial direction of the main roller assembly 12 on the outer side of the side wall where the second loading and unloading opening 112 of the cutting frame 11 is located, and their heights are both lower than the second loading and unloading opening 112.

[0066] The above setting method is beneficial to realize the compact structure of the wire cutting machine 100, reduce the space occupation of the wire cutting machine 100, and improve the layout flexibility of the wire cutting machine 100.

[0067] The gas path system 6 is mainly used to supply gas to the gas-using components in the wire cutting machine 100, such as providing high-pressure or low-pressure gas to pneumatic valves, pneumatic seals, oil and gas lubrication parts, etc. In this application, the gas path component is arranged on the frame on the outer side of the side wall where the second loading and unloading opening 112 is located. After being set up, the gas path system 6 avoids the second loading and unloading opening 112.

[0068] See Figure 4 and Figure 5, In another possible implementation, the wire cutting machine 100 is a slicing machine, which includes a cutting assembly 1, a feeding assembly 2, a wire winding chamber assembly 3, an electric control cabinet 4, a liquid circuit system 5 and a gas circuit system 6. Among them, the arrangements of the cutting assembly 1, the feeding assembly 2, the wire winding chamber assembly 3 and the gas circuit system 6 are the same as those in the above embodiment. The difference is that in this implementation, the electric control cabinet 4 is arranged on one side of the cutting frame 11 along the radial direction of the main roller assembly 12. Specifically, the electric control cabinet 4 is arranged on the side where the fourth loading and unloading port 114 is located and is closely arranged adjacent to the frame where the gas circuit system 6 is installed.

[0069] In addition, the pipeline assembly 51 and the liquid supply cylinder 52 in the liquid circuit system 5 are arranged on the same side of the cutting frame 11 along the radial direction of the main roller assembly 12, and the pipeline assembly 51 is located above the liquid supply cylinder 52. Specifically, the pipeline assembly 51 is arranged on the side where the third loading and unloading port 113 is located, and a part of the liquid supply cylinder 52 is inserted under the frame where the gas circuit system 6 is installed.

[0070] For existing slicing machines, their usual layout is as follows: loading and unloading ports are opened on the front side of the cutting assembly, the wire winding chamber assembly is located at the rear side of the cutting assembly, the electric control cabinet is arranged above the wire winding chamber assembly, and the liquid and gas circuit systems are both located at the rear side of the wire winding chamber assembly. In this way, the overall length of the equipment is long, reducing the flexibility of the equipment placement in the workshop, and it can only be loaded and unloaded through the front loading and unloading port. In this application, by setting four loading and unloading ports on the cutting frame 11 of the cutting assembly 1 and adjusting the installation positions of the other assemblies and systems, the overall structure of the slicing machine is made compact, facilitating the transportation of the equipment. At the same time, all four loading and unloading ports can be used for loading and unloading, which is also beneficial to improving the flexibility of the equipment placement in the workshop and providing favorable conditions for the transformation of automatic loading and unloading.

[0071] Of course, the two above-listed implementations are merely exemplary and are not intended to limit the protection scope of this application. Without departing from the principle of this application, those skilled in the art can adjust the above implementations so that the wire cutting machine 100 of this application is applicable to more specific application scenarios. For example, on the premise of ensuring that the four loading and unloading ports can effectively perform loading and unloading, those skilled in the art can adjust the specific installation positions of the feeding assembly 2, the wire winding chamber assembly 3, the electric control cabinet 4, the liquid circuit system 5 and the gas circuit system 6.

[0072] Next, refer to Figure 3 and Figure 6 , to introduce the wire cutting machine set of this application.

[0073] As Figure 3 and Figure 6 shown, this application also provides a wire cutting machine set, which includes a plurality of wire cutting machines 100 arranged closely. Taking Figure 3Taking the shown as an example, this wire cutting machine set includes two wire cutting machines 100 arranged back to back. In other words, the second loading and unloading ports 112 of the two wire cutting machines 100 face each other, and the first loading and unloading ports 111 face away from each other. Among them, both of the two wire cutting machines 100 are the slicing machines in the above-mentioned first embodiment.

[0074] Taking Figure 6 Taking the shown as an example, this wire cutting machine set includes two wire cutting machines 100 arranged back to back. In other words, the second loading and unloading ports 112 of the two wire cutting machines 100 face each other, and the first loading and unloading ports 111 face away from each other. Among them, both of the two wire cutting machines 100 are the slicing machines in the above-mentioned second embodiment.

[0075] The above-mentioned wire cutting machine set can achieve a multi-station compact layout without affecting loading and unloading, greatly reducing the floor area of the workshop and improving the overall production capacity of the workshop.

[0076] Of course, the specific number and layout form of the wire cutting machines 100 are not unique, and those skilled in the art can adjust the number and layout of the wire cutting machines 100 based on the specific workshop environment. For example, the number of the wire cutting machines 100 can also be adjusted to three, four or even more. Again, for another example, the wire cutting machines 100 in the wire cutting machine set can also be arranged in a way that the first loading and unloading ports 111 face each other while the second loading and unloading ports 112 face away from each other.

[0077] Those skilled in the art can understand that although some of the embodiments described herein include certain features included in other embodiments rather than other features, the combination of the features of different embodiments means that it is within the scope of this application and forms different embodiments. For example, in the claims of this application, any one of the claimed embodiments can be used in any combination.

[0078] So far, the technical solutions of this application have been described in conjunction with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of this application is obviously not limited to these specific embodiments. Without departing from the principle of this application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this application.
