Description

Technical Field

[0001] The present invention belongs to the field of silicon rod slicing, and specifically relates to a multi-station slicing machine. Background Art

[0002] Silicon wafer forming refers to the process of making silicon wafers from silicon rods. Currently, multi-wire cutting is the most common method for slicing. In the actual production process, the slicing machine often has only one cutting area assembly, that is, one cutting area, and only one cutting station can be formed in one cutting area. This results in that only the brittle material on a single cutting station can be cut in one cutting cycle, severely limiting the cutting ability and efficiency of the slicing machine. To improve the cutting ability and efficiency by increasing the number of slicing machines, it will bring the problem of occupying more factory floor area. Many enterprises cannot expand the production scale because they cannot expand the factory building area. Increasing the number of slicing machines also means increasing the investment in equipment funds. For high-price slicing machines, it is also a factor that is not easy for enterprises to achieve the expansion of production scale. The realization of the heat exchange function of the slicing machine requires numerous pipelines to circulate. However, the pipelines of the existing equipment are relatively scattered, which is not conducive to management. The existing slicing machines all have a set of cutting fluid supply and heat exchange components corresponding to one cutting station. Once the cutting fluid supply and heat exchange components fail, it will directly cause damage to brittle materials such as silicon rods, not only affecting the cutting quality, but also wasting high-cost silicon rod raw materials. At the same time, the shutdown of production will also reduce the production efficiency of the enterprise. The existing slicing machines usually require professional technicians to carry out on-site installation work for up to several weeks, which is not conducive to serving customers at a long distance, and has high requirements for the technical level of the installation personnel, so the personnel cost is also high.

[0003] Therefore, the existing technology still needs to be further developed and improved. Summary of the Invention

[0004] In view of the various deficiencies of the existing technology, to solve the above problems, a multi-station slicing machine is proposed. The present invention provides the following technical solutions:

[0005] A multi-station slicing machine includes at least two cutting area assemblies for slicing, a cutting fluid supply component for providing cutting fluid, a cutting fluid heat exchange component for cooling the cutting fluid, and a coolant heat exchange component for cooling the slicing machine equipment. Each cutting area assembly is correspondingly provided with a cutting fluid heat exchange component, and multiple cutting area assemblies share a coolant heat exchange component.

[0006] Further, the cutting area assemblies are arranged in central symmetry or left-right symmetry.

[0007] Further, the multi-station slicing machine is a double-station slicing machine including two cutting area assemblies. The two cutting area assemblies are arranged in left-right symmetry, and the cutting fluid supply component, the cutting fluid heat exchange component, the coolant heat exchange component, and the electrical assembly are located in the middle position between the two cutting area assemblies.

[0008] Further, the electrical assembly includes an electrical control cabinet centrally arranged on one side or electrical control cabinets respectively arranged on both sides based on the two cutting area assemblies.

[0009] Further, the cutting fluid supply assembly includes a cutting fluid supply cylinder for storing cutting fluid and a supply pump for pumping the cutting fluid to the cutting area assembly, and the supply pump pumps the cutting fluid in the cutting fluid supply cylinder to each cutting area assembly.

[0010] Further, the cutting fluid heat exchange assembly includes a filter barrel for filtering the pumped cutting fluid and a cutting fluid heat exchanger for cooling the cutting fluid. The cutting fluid is first filtered by the filter barrel and then flows into the cutting fluid heat exchanger for cooling, and then is transported to each cutting area.

[0011] Further, the coolant heat exchange assembly includes a coolant water tank for storing coolant, a coolant pump for pumping the coolant, and a coolant heat exchanger for cooling the coolant. The coolant flowing through the equipment of the cutting area assembly is cooled by the coolant heat exchanger and then flows back to the coolant water tank.

[0012] Further, both the coolant pump and the coolant heat exchanger are arranged above the coolant water tank.

[0013] Further, each cutting area assembly is physically connected through the same connection structure, and the cutting fluid supply assembly, the cutting fluid heat exchange assembly, and the coolant heat exchange assembly are connected to each cutting area assembly through the connection structure to form a whole.

[0014] Further, each cutting area assembly is detachably connected to the connection structure. Connection sites for connecting each cutting area assembly are provided on the connection structure, and reserved connection sites for connecting more cutting area assemblies are also provided on the connection structure.

[0015] Further, the connection structure is a connection cross beam or a connection frame.

[0016] Further, the cutting area assembly includes a protection mechanism and a feeding mechanism and a wire saw mechanism located inside the protection mechanism.

[0017] Beneficial effects:

[0018] 1. By providing at least two cutting area assemblies, the cutting capacity of the slicing machine is increased by at least more than one time;

[0019] 2. By integrally arranging the cutting fluid supply assembly, the cutting fluid heat exchange assembly, and the electrical assembly, making full use of the upper and lower space layout, reducing the floor area of the equipment, improving the utilization rate of the factory building space, thereby reducing the input cost of the silicon wafer manufacturer, and at the same time facilitating centralized management and improving the utilization rate of the equipment;

[0020] 3. By sharing the coolant heat exchange components, the equipment configuration cost is reduced;

[0021] 4. By centrally arranging the cutting fluid heat exchange components and the coolant heat exchange components, it is beneficial to the centralized layout of the circulation pipelines and the centralized maintenance of the heat exchange equipment, facilitating management;

[0022] 5. By setting each cutting fluid supply component and the cutting fluid heat exchange component as high-power and high-throughput components, when a certain set of cutting fluid supply components and the cutting fluid heat exchange component fail, there are spare components reserved, achieving high production efficiency without stopping work or production;

[0023] 6. Through the same connection structure, the total cutting area assemblies are physically rigidly connected, which is convenient for movement and hoisting. At the same time, the stability of the internal connection of the equipment is ensured, avoiding phenomena such as interface fracture during handling. At the same time, the connection structure is suitable for pre-installation work, reducing the technical requirements for on-site installers. Description of the Drawings

Detailed implementation manners

[0042] To enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Based on the embodiments in this application, other similar embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application. In addition, the directional terms mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only references to the directions of the accompanying drawings. Therefore, the directional terms used are for illustration rather than limitation of the present invention.

[0043] As Figure 1-17 shown, a multi-station slicing machine includes at least two cutting area assemblies 100 for slicing, a cutting fluid supply assembly 210 for supplying cutting fluid, a cutting fluid heat exchange assembly 220 for cooling the cutting fluid, and a coolant heat exchange assembly 230 for cooling the slicing machine equipment. Each cutting area assembly 100 is correspondingly provided with a cutting fluid heat exchange assembly 220, and multiple cutting area assemblies 100 share a coolant heat exchange assembly 230. During the cutting process, the cooling of the equipment is achieved by the coolant circulating in the coolant heat exchange assembly 230, and the cooling of the cutting surface of the hard and brittle material is achieved by the cutting fluid circulating in the cutting fluid heat exchange assembly 220. The two work together to respectively enable the cutting process to be carried out within the normal temperature range, avoiding the decline in cutting quality caused by overheating of the equipment or the material. Multiple cutting area assemblies 100 sharing a coolant heat exchange assembly 230 reduces the number of coolant heat exchange assemblies 230 provided, reduces the equipment cost of the enterprise, and at the same time, the shared assembly promotes the centralized setting of multiple cutting area assemblies 100, which is beneficial to the integration of the overall equipment and reduces the floor area.

[0044] Further, each cutting area assembly 100 is arranged in central symmetry or left-right symmetry, and the cutting liquid supply assembly 210, the cutting liquid heat exchange assembly 220, and the coolant heat exchange assembly 230 are centrally arranged at the middle position of each cutting area assembly. By connecting multiple cutting area assemblies 100 to the cutting liquid supply assembly 210, the cutting liquid heat exchange assembly 220, and the coolant heat exchange assembly 230 arranged in the same area, each cutting area assembly 100 can obtain the cutting liquid and coolant required for cutting from a cutting liquid supply assembly 210, a cutting liquid heat exchange assembly 220, and a coolant heat exchange assembly 230, thereby achieving the multi-station goal of the slicing machine equipment, greatly reducing the floor area, improving the utilization rate of the factory building space, increasing the production capacity per unit area by several times. At the same time, multiple cutting area assemblies 100 share a set of cutting liquid supply assembly 210, cutting liquid heat exchange assembly 220, and coolant heat exchange assembly 230, reducing the purchase cost of the cutting liquid supply assembly 210, the cutting liquid heat exchange assembly 220, and the coolant heat exchange assembly 230 equipment. The symmetric arrangement is conducive to effectively managing each cutting area assembly 100 in a regular arrangement, facilitating enterprise management, and at the same time optimizing the utilization of the factory building space, with the least land and equipment cost investment, and the most efficient increase in the production capacity per unit area.

[0045] Furthermore, the multi-station slicing machine is a double-station slicing machine including two cutting area assemblies 100, and the two cutting area assemblies 100 are arranged symmetrically left and right. The cutting liquid supply assembly 210, the cutting liquid heat exchange assembly 220, the coolant heat exchange assembly 230, and the electrical assembly are located in the middle position between the two cutting area assemblies 100. The double-station slicing machine is the optimal mode among the multi-station slicing machines. The factory building space occupied by the double-station slicing machine is smaller than the overall equipment space of the original slicing machine, so that the production capacity can be directly doubled by replacing the equipment without changing the factory building area. A cutting liquid supply assembly 210, a cutting liquid heat exchange assembly 220, a coolant heat exchange assembly 230, and an electrical assembly are arranged in the middle of the two cutting area assemblies 100 of the double-station slicing machine, which is convenient for unified management. One of the two cutting area assemblies 100 of the double-station slicing machine can be used alone for cutting work, and the oil-gas assembly and the electrical assembly of the other one do not need to be opened. The cutting liquid supply assembly 210 and the cutting liquid heat exchange assembly 220 of the other one can be shared or used separately. Each cutting liquid supply assembly 210 and cutting liquid heat exchange assembly 220 are set as high-power and high-throughput components. The cutting liquid supply assembly 210 and the cutting liquid heat exchange assembly 220 can drive the two cutting area assemblies 100 to work simultaneously, and pipelines connecting multiple cutting area assemblies 100 are correspondingly arranged. At this time, another set of cutting liquid supply assembly 210 and cutting liquid heat exchange assembly 220 can be used as standby equipment. Since the heat generated by the equipment itself is relatively low, the coolant heat exchange assembly 230 is shared by the two cutting area assemblies 100, and there is no need to set up another set of standby components separately, reducing the production cost of the equipment. The oil-gas assembly provides functions such as hydraulic pressurization, running-in lubrication, and air path sealing for each device of the slicing machine. The oil-gas assembly includes a hydraulic component, a pneumatic component, and an oil-gas component. The hydraulic component mainly provides hydraulic pressurization for the equipment parts. The pneumatic component mainly performs air path back blowing and seals the air path for the equipment parts. In the oil-gas component, a part of the components are mainly used to provide air path sealing and adjust the air pressure for the equipment parts; another part of the components provide lubricating oil for the equipment bearing parts through oil pipes to achieve the running-in lubrication effect.

[0046] Further, the electrical assembly includes an electrical control cabinet 310 centrally disposed on one side or electrical control cabinets 310 respectively disposed on both sides based on the two cutting area assemblies 100. Each cutting area assembly 100 is configured with a set of electrical assembly. The two sets of electrical assemblies can be respectively provided with electrical control cabinets 310 for protection and distinction, or can be integrated and operated in one electrical control cabinet 310. The layout with two electrical control cabinets 310 between the two cutting area assemblies 100 is as follows: the two electrical control cabinets 310 are both fixed on the connecting structure and are respectively located on both sides of the connecting structure. One of the electrical control cabinets 310 is disposed on the top of the centralized cooling assembly, and the other electrical control cabinet 310 is disposed on the top of the oil and gas assembly. The layout with one electrical control cabinet 310 between the two cutting area assemblies 100 is as follows: the electrical control cabinet 310 is fixed on one side of the connecting structure, and the cutting liquid supply assembly 210, the cutting liquid heat exchange assembly 220, the coolant heat exchange assembly 230, and the oil and gas assembly are all disposed on the other side of the electrical control cabinet 310. An operation box 320 is further provided on each cutting area assembly 100. The operation box 320 is signal-connected to the electrical assembly in the electrical control cabinet 310 to provide a man-machine interface and signal input for the electrical control cabinet 310, facilitating the operator to set the cutting process. The liquid outlet pipe of the cutting liquid supply assembly 210 is communicated with the cutting liquid heat exchange assembly 220. The cutting liquid heat exchange assembly 220 cools the liquid output by the cutting liquid supply assembly 210 and then transports it to each cutting area assembly 100. The cutting liquid heat exchange assembly 220 and the coolant heat exchange assembly 230 are disposed behind or above the cutting liquid supply assembly 210. Taking the double-station slicing machine as an example, when the electrical control cabinets 310 are separately disposed on both sides of the connecting structure, the centralized cooling assembly is disposed behind the cutting liquid supply assembly 210 at this time, and the corresponding electrical control cabinets 310 are respectively disposed above the centralized cooling assembly and the cutting liquid supply assembly 210, so as to maximize the utilization of the space between the two cutting area assemblies 100; when the electrical control cabinet 310 is disposed on one side of the connecting structure, the centralized cooling assembly is disposed above the cutting liquid supply assembly 210 at this time, and the floor space is optimally saved through the up-and-down structure. The cutting liquid heat exchange assembly 220 is disposed on both sides of the coolant heat exchange assembly 230. Taking the double-station slicing machine as an example, the coolant heat exchange assembly 230 is a part shared by the two cutting area assemblies 100. Therefore, it needs to be disposed as close to the central position as possible so that the distances to the two cutting area assemblies 100 are the same, reducing the layout of the lengths of different specifications of pipelines, facilitating installation and maintenance. The cutting liquid heat exchange assembly 220 is installed at the vacant positions on both sides of the corresponding coolant heat exchange assembly 230, making the heat exchange assemblies centralized, facilitating management and maintenance, and at the same time facilitating the centralized arrangement of the pipelines.

[0047] Furthermore, the cutting liquid supply assembly 210 includes a cutting liquid supply cylinder 211 for storing cutting liquid of multiple cutting area assemblies 100 and a liquid supply pump 212 for pumping cutting liquid to multiple cutting area assemblies 100. The liquid supply pump 212 pumps the cutting liquid in the cutting liquid supply cylinder 211 to each cutting area assembly 100. The liquid supply pump 212 provides cutting liquid for cooling and lubrication for all cutting areas. The liquid supply pump 212 extracts the cutting liquid from the cutting liquid supply cylinder 211 and distributes it to each cutting area through different pipelines. A liquid collecting port is provided at the bottom of each cutting area. The cutting liquid recovered from the liquid collecting port is then collected into the cutting liquid supply cylinder 211 through the pipeline to realize the recycling of the cutting liquid. A liquid extraction pipe assembly is also provided on the cutting liquid supply cylinder 211, and the diaphragm pump extracts the waste liquid used for cutting through the liquid extraction pipe assembly. A limit buffer seat is also provided on one side of the cutting liquid supply cylinder 211 to prevent hard collision with other equipment during the pushing and pulling process of the assembly.

[0048] Furthermore, the cutting liquid heat exchange component 220 includes a filter barrel 223 for filtering and pumping the cutting liquid and a cutting liquid heat exchanger 224 for cooling the cutting liquid. The cutting liquid is first filtered by the filter barrel 223 and then flows into the cutting liquid heat exchanger 224 for cooling, and then transported to each cutting area. The filter barrel 223 is connected to the cutting liquid supply cylinder 211 through a pipeline. The cutting liquid supply cylinder 211 outputs the cutting liquid to the filter barrel 223 through the liquid supply pump 212 to filter out particulate impurities. Then, after passing through the integrated heat exchange component, the cutting liquid passes through the flow monitoring component preset on the pipeline in front of the cutting liquid supply port 221 at a set temperature, and then outputs a preset specific flow through the mass flow meter 222 in the flow monitoring component, and finally reaches the cutting area assembly 100 through the cutting liquid supply port 221 to cool the hard and brittle material being cut. When the equipment is running, the cutting liquid first returns to the cutting liquid supply cylinder through the mass flow meter 222, and does not enter the cutting chamber 111, so that the flow rate of the cutting liquid is quickly increased, saving time. The filter barrel 223 includes at least one filter barrel 223 and a drain clamp valve disposed at the bottom of each filter barrel 223. The filter barrel 223 is fixed on the bottom crossbeam 440, and the bottom crossbeam 440 is fixed to the integrated heat exchange assembly. The drain clamp valve is a ball valve. After the equipment is cut once, the ball valve is opened to discharge the liquid inside the filter barrel 223. The cutting liquid must pass through the pressure detection device before entering the filter barrel 223 after being output by the liquid supply pump 212 to monitor the pressure of the filter barrel 223 in real time to prevent blockage.

[0049] Furthermore, the coolant heat exchange assembly 230 includes a coolant water tank 231 for storing coolant, a coolant pump 233 for pumping the coolant, and a coolant heat exchanger 232 for cooling the coolant. The coolant flowing through each cutting area assembly 100 device is cooled by the coolant heat exchanger 232 and then flows back to the coolant water tank 231. A centralized cooling pipe and a centralized liquid return pipe are provided corresponding to the heat exchange assembly. The coolant stored in the coolant water tank 231 is conveyed to each device of the slicing machine through the centralized cooling pipe to cool each device. The used coolant then returns to the coolant water tank 231 through the centralized liquid return pipe, and the coolant heat exchanger 232 exchanges heat for the coolant in the coolant water tank 231. A factory cooling water circulation pipeline is provided corresponding to the heat exchange assembly. A coolant inlet and a coolant outlet are provided on one side of the coolant heat exchanger 232. The low-temperature cooling water enters the centralized cooling assembly from the factory cooling water inlet to cool the cutting fluid heat exchanger 224 and the coolant heat exchanger 232. The used factory cooling water flows out from the coolant outlet and returns to the factory cooling water large circulation. A temperature monitoring device is provided at the factory cooling water inlet to monitor in real time whether the incoming factory cooling water is the cooling water of the required temperature.

[0050] Furthermore, both the coolant pump 233 and the coolant heat exchanger 232 are arranged above the coolant water tank 231. Making full use of the space of the integrated heat exchange assembly, the coolant heat exchanger 232 is arranged directly above the coolant water tank 231 closest to it, cooling the coolant in the coolant water tank 231 in a timely manner. At the same time, the setting of long pipelines is avoided, the risk of pipeline leakage is reduced, and it is convenient for equipment maintenance.

[0051] Furthermore, each cutting area assembly 100 is physically connected through the same connection structure, and the cutting liquid supply assembly 210, the cutting fluid heat exchange assembly 220, and the coolant heat exchange assembly 230 are connected to each cutting area assembly 100 through the connection structure to form an integral whole. By physically connecting the cutting liquid supply assembly 210, the cutting fluid heat exchange assembly 220, the coolant heat exchange assembly 230 and each cutting area assembly 100 rigidly, it is convenient for the whole machine to be moved and hoisted. At the same time, the stability of the internal connection of the equipment is ensured, and phenomena such as interface fracture during handling are avoided. At the same time, the connection structure is suitable for pre-installation work, reducing the technical requirements for on-site installers.

[0052] Furthermore, each cutting area assembly 100 is detachably connected to the connection structure. The connection structure is provided with connection sites for connecting each cutting area assembly 100, and at the same time, the connection structure is also provided with reserved connection sites for connecting more cutting area assemblies 100. Users can fix the required number of cutting area assemblies 100 on the connection structure according to actual needs. The connection sites are provided with reserved pipelines corresponding to the cutting liquid supply assembly 210, the cutting liquid heat exchange assembly 220, and the coolant heat exchange assembly 230. The reserved pipelines are provided with reserved valves for opening and closing the connection between the cutting area assembly 100 at the connection site and the cutting liquid supply assembly 210, the cutting liquid heat exchange assembly 220, and the coolant heat exchange assembly 230. At the same time, the number of existing cutting area assemblies 100 can be restricted through the reserved valves, saving resources.

[0053] Further, the connecting structure is a connecting crossbeam or a connecting frame. Further, the connecting structure is a connecting crossbeam, and the two cutting area assemblies 100 are arranged symmetrically about the connecting crossbeam. By connecting the two cutting area assemblies 100 to the cutting fluid supply assembly 210, the cutting fluid heat exchange assembly 220, and the coolant heat exchange assembly 230 arranged in the same area, each cutting area assembly 100 can obtain the cutting fluid and coolant required for cutting from one cutting fluid supply assembly 210, the cutting fluid heat exchange assembly 220, and the coolant heat exchange assembly 230, thereby achieving the double-station goal of the slicing machine equipment. The factory building space occupied by the double-station slicing machine is smaller than the overall equipment space of the original slicing machine, so that the production capacity can be directly doubled by replacing the equipment without changing the factory building area. The symmetrical arrangement on the left and right is conducive to effectively managing the cutting area assemblies 100 in a regular arrangement, facilitating enterprise management, and at the same time optimizing the use of the factory building space to improve the production capacity per unit area with the least land and equipment cost investment. Further, the connecting crossbeam includes a top crossbeam 410, and top connection seats 420 for connecting the two cutting area assemblies 100 are arranged on both sides of the top crossbeam 410. Further, an electrical connection seat 430 for fixing the electrical assembly is also arranged on the top crossbeam 410. The electrical assembly includes an electrical control cabinet 310 centrally arranged on one side or electrical control cabinets 310 respectively arranged on both sides based on the two cutting area assemblies 100. The electrical control cabinet 310 is fixedly connected to the electrical connection seat 430. Each cutting area assembly 100 is configured with a set of electrical assemblies. The two sets of electrical assemblies can be provided with electrical control cabinets 310 for protection and distinction respectively, or can be integrated and operated in one electrical control cabinet 310. The layout with two electrical control cabinets 310 between the two cutting area assemblies 100 is that the two electrical control cabinets 310 are both fixed on the connecting structure and are respectively located on both sides of the connecting structure. One of the electrical control cabinets 310 is arranged on the top of the centralized cooling assembly, and the other electrical control cabinet 310 is arranged on the top of the oil and gas assembly. The layout with one electrical control cabinet 310 between the two cutting area assemblies 100 is that the electrical control cabinet 310 is fixed on one side of the connecting structure, and the cutting fluid supply assembly 210, the cutting fluid heat exchange assembly 220, the coolant heat exchange assembly 230, and the oil and gas assembly are all arranged on the other side of the electrical control cabinet 310. An operation box 320 is also arranged on each cutting area assembly 100. The operation box 320 is signal-connected to the electrical assembly in the electrical control cabinet 310 to provide a man-machine interface and signal input for the electrical control cabinet 310, facilitating the operator to set the cutting process. Further, the connecting crossbeam includes a bottom crossbeam 440, and bottom connection seats 450 for connecting the two cutting area assemblies 100 are arranged at both ends of the bottom crossbeam 440.

[0054] Further, the cutting area assembly 100 includes a protection mechanism and a feeding mechanism and a wire saw mechanism located inside the protection mechanism.

[0055] Among them, the wire saw mechanism includes a support frame 110, a main roller shaft 120 for supporting the cutting wire to form a cutting position, a winding and arranging wire assembly for winding and unwinding the cutting wire, and a turning wheel assembly for guiding the cutting wire to reciprocate between the main roller shaft 120 and the winding and arranging wire assembly. The support frame 110 includes a cutting chamber 111 and a wire winding chamber 112. The winding and arranging wire assembly is fixed inside the wire winding chamber 112, the main roller shaft 120 is fixed inside the cutting chamber 111, and the wire winding chamber 112 is arranged below the cutting chamber 111. By dividing the support frame 110 vertically into a cutting chamber 111 and a wire winding chamber 112, it is possible to prevent the cutting debris generated during the cutting process in the cutting chamber 111 from cutting the cutting wire in the wire winding chamber 112, ensuring the safety of the cutting wire. At the same time, the arrangement of the upper and lower structures occupies less land, so that enterprises can increase more wire saw equipment under the condition of the same land area, thereby improving the production efficiency per unit land area.

[0056] Further, the turning wheel assembly includes a wire winding turning wheel 130, a tension turning wheel 150, and a main roller shaft turning wheel 140. The cutting wire sequentially passes through the wire winding turning wheel 130, the tension turning wheel 150, and the main roller shaft turning wheel 140 from the winding and arranging wire assembly to reach the main roller shaft 120. The wire arranging turning wheel 130, the tension turning wheel 150, and the main roller shaft turning wheel 140 are symmetrically distributed on both sides of the main roller shaft 120 with the main roller shaft 120 as the axis of symmetry, ensuring that the cutting wire can reciprocate along the same path on both sides of the main roller shaft 120 and ensuring the stability of the cutting wire on the main roller shaft 120.

[0057] Further, the tension turning wheel 150 is arranged above the wire winding turning wheel 130, and the main roller shaft turning wheel 140 is arranged above the tension turning wheel 150. The main shaft of the tension turning wheel 150 is arranged above the main shaft of the wire winding turning wheel 130, and the main shaft of the main roller shaft turning wheel 140 is arranged above the main shaft of the tension turning wheel 150, avoiding interference between the cutting wires between different guide wheels.

[0058] Further, the wheel surface of the tension turning wheel 150 is coplanar with the wheel surface of the wire winding turning wheel 130. The coplanar structure is conducive to avoiding the phenomenon of the cutting wire curling between the two wheels. Further, the lowest point of the tension turning wheel 150 and the highest point of the wire winding turning wheel 130 are on the same horizontal line. At this time, it can ensure that the cutting wire participates in cutting with the shortest distance, reducing the probability of the cutting wire breaking during the winding and unwinding process.

[0059] Further, the tension turning wheel 150 is arranged at the junction of the cutting chamber 111 and the wire winding chamber 112. Arranging it at the junction of the cutting chamber 111 and the wire winding chamber 112 can ensure that the tension turning wheel 150 is arranged between the main roller shaft 120 and the winding and arranging wire assembly. Cooperating with the main roller shaft turning wheel 140 and the wire winding turning wheel 130 arranged on both sides of the tension turning wheel 150, it achieves the dual functions of guiding and tension adjustment.

[0060] Further, the tension turning wheel 150 is arranged on the outer side of the support frame 110 along the axis direction of the main roller shaft 120. A through hole 113 for the cutting wire to pass through the cutting chamber 111 and the wire winding chamber 112 is provided on the corresponding support frame 110. The tension turning wheel 150 is arranged on the outer side of the support frame 110, which is simple and convenient to set, and avoids the interference of the tensioning assembly connected to the tension turning wheel 150 on the wire winding and arranging assembly inside the support frame 110 or the main roller shaft 120. A through hole 113 is correspondingly opened on the support frame 110. The through hole 113 includes but is not limited to a through hole or a notch, so that the cutting wire reciprocates inside the support frame 110 after passing through the through hole 113, without disturbing the protective cover 160 arranged outside the support frame 110, which is beneficial to protecting the cutting wire and avoiding the occurrence of the situation that the cutting wire is damaged by external force.

[0061] Further, there are two through holes 113 corresponding to the upper and lower edges of the tension turning wheel 150, and the two through holes 113 respectively lead to the cutting chamber 111 and the wire winding chamber 112. By correspondingly arranging the through holes 113 for the cutting chamber 111 and the wire winding chamber 112 respectively, the mutual independence of the two compartments will not be damaged. At the same time, the separated through holes 113 play a role in limiting the cutting wire, avoiding the mutual winding between the cutting wires when accidents such as wire breakage occur.

[0062] Further, the highest point of the inner wall of the through hole 113 is higher than the highest point of the tension turning wheel 150, and the lowest point of the inner wall of the through hole 113 is lower than the lowest point of the tension turning wheel 150. Since the swinging amplitude of the tension turning wheel 150 is limited, setting the highest point of the through hole 113 higher than the highest point of the tension turning wheel 150 and the lowest point lower than the lowest point of the tension turning wheel 150 can ensure that the cutting wire is not affected by the limit of the through hole 113 during the adjustment of the tensioning assembly, and avoid the wear of the cutting wire on the through hole 113 and affect the cutting quality.

[0063] Further, it includes a tensioning assembly fixed to the outer wall of the support frame 110. The tensioning assembly includes a tension motor 151 and a tension arm 152. The tension idler 150 is fixedly connected to the output shaft of the tension motor 151 through the tension arm 152. The tension motor 151 is fixed to the support frame 110 through a tension motor base 153. A limit rod 154 for restricting the swing amplitude of the tension arm 152 is provided on the tension motor base 153. The tension motor 151 is fixed to the support frame 110 through the tension motor base 153. The tension motor base 153 is preferably fixed to the front end of the support frame 110, on the same side as the front end of the main roller shaft 120. The tension motor base 153 is an L-shaped fixing base, and a reinforcing rib plate for strengthening the connection strength is provided at the angle. The two L-shaped fixing bases on both sides are arranged oppositely, and the tension motors 151 fixed to the fixing bases are arranged oppositely and the output shafts of the tension motors 151 all face outward, facilitating the fixing of the tension arm 152 capable of rotating around the output shaft on the output shaft. Preferably, the tension motor bases 153 are arranged symmetrically left and right with the midline of the support frame 110 as the axis of symmetry, and the corresponding tension motors 151 and tension arms 152 are both arranged symmetrically left and right. The free end of the tension arm 152 is connected to the central axis of the tension idler 150. By the rotation of the output shaft of the tension motor 151, the tension arm 152 is driven to make a circular motion around the output shaft, thereby driving the tension idler 150 fixed on the tension arm 152 to move back and forth relative to the support frame 110, achieving the purpose of increasing or decreasing the tension of the cutting wire. There are two limit rods 154 arranged in parallel. The length of the limit rod 154 is greater than the distance from the tension arm 152 to the tension motor base 153, ensuring that the tension arm 152 always swings inside the two limit rods 154, facilitating the installation process of the cutting wire, ensuring that the tension idler 150 is always between the main roller shaft idler 140 and the winding and arranging idler 130, and at the same time avoiding damage to the cutting wire caused by excessive swinging.

[0064] Further, the main roller shaft idler 140 is arranged in the cutting chamber 111. The main roller shaft idler 140 is arranged at a position close to the main roller shaft 120, ensuring that the cutting wire is introduced onto the main roller shaft 120 at the shortest distance. The main roller shaft idler 140 is arranged at the two side edges of the cutting chamber 111 and on both sides of the main roller shaft 120, not affected by the cutting process, saving wiring space and reducing the risk of wire breakage.

[0065] Further, the wheel surface of the main roller shaft turning wheel 140 is inclined towards the side of the main roller shaft 120, so that the cutting line is guided from the tension turning wheel 150 to the main roller shaft 120. The main roller shaft turning wheel 140 is inclined relative to the horizontal plane, so as to ensure that the main roller shaft turning wheel 140 can be arranged on both sides of the main roller shaft 120 rather than directly below it, thereby ensuring that the cutting line wound on the main roller shaft turning wheel 140 is not affected by the debris falling during the cutting process. The wheel surface of the main roller shaft turning wheel 140 is vertically arranged relative to the wheel surface of the tension turning wheel 150, and the tension turning wheel 150 is in a vertical state. The cutting line is introduced from above the tension turning wheel 150 to below the main roller shaft turning wheel 140, and then guided to the main roller shaft 120 through the inclined wheel surface. Preferably, the connection line between the highest point of the tension turning wheel 150 and the lowest point of the main roller shaft turning wheel 140 is close to the horizontal line state.

[0066] Further, the axis of the main roller shaft turning wheel 140 is fixed on the adjusting seat 141, and the main roller shaft turning wheel 140 is fixed in the cutting chamber 111 through the adjusting seat 141. The angle formed by the adjusting seat 141 and the bottom surface of the cutting chamber 111 is adjustable, corresponding to the adjustable inclination angle of the wheel surface of the main roller shaft turning wheel 140. The adjusting seat 141 includes an adjusting base and an adjusting rod. The bottom end of the adjusting rod is rotatably connected to the adjusting base, and the top end of the adjusting rod fixes the central axis of the main roller shaft turning wheel 140. Rotate the adjusting rod according to the height of the main roller shaft 120 so that the wheel surface of the main roller shaft turning wheel 140 is tangent to the main roller shaft 120, thereby reducing unnecessary friction of the cutting line on the main roller shaft turning wheel 140 and the main roller shaft 120 and reducing the wear of the cutting line.

[0067] Further, the bottom of the adjusting seat 141 is fixed in the cutting chamber 111 through the sliding assembly 142. Different cutting wire meshes usually need to be set for different workpieces to be cut, which results in different winding turns of the cutting line on the main roller shaft 120, and further results in different winding areas and the positions of the cutting lines at both ends. Slide rails are arranged along the axis direction of the main roller shaft 120 on both edges of the cutting chamber 111. The bottom of the adjusting seat 141 is fixed with sliders corresponding to the slide rails, and the sliders slide on the slide rails to drive the adjusting seat 141 to move back and forth in the cutting chamber 111, so as to conveniently adjust the winding turns of the cutting line on the main roller shaft 120, and also conveniently adjust the cutting line to enter the wire groove on the main roller shaft 120 from the main roller shaft turning wheel 140 at the shortest distance, avoiding wear of the cutting line on the wheel frame of the main roller shaft turning wheel 140 or the edge of the wire groove.

[0068] Further, the winding and wiring turning wheel 130 is arranged in the winding chamber 112, and the winding and wiring turning wheel 130 is fixed on the winding and wiring assembly. The winding and wiring turning wheel 130 is arranged close to the winding and wiring assembly, so that the cutting line is led out from the winding and wiring assembly with the shortest path, reducing the risk of wire breakage.

[0069] Further, a tension sensor is provided on the central axis of the wire winding and turning wheel 130 or the tension turning wheel 150. By arranging the tension sensor at the axis center of the wire winding and turning wheel 130 or the tension turning wheel 150, it is used to monitor the tension state of the cutting wire in real time and cooperate with the tensioning component for dynamic adjustment, so as to avoid the decline of cutting quality caused by the too loose cutting wire or the wire breakage caused by the too tight cutting wire.

[0070] Further, the wire winding and arranging component includes a wire winding shaft component for winding the cutting wire and a wire arranging component for guiding the incoming and outgoing path of the cutting wire on the wire winding shaft component. The wire winding shaft component includes a wire winding motor 131 and a wire storage wheel 132 arranged at the output end of the wire winding motor 131. The wire arranging component is arranged above the wire winding shaft component. There are two sets of wire winding and arranging components, which are symmetrically arranged on both sides of the main roller shaft 120 corresponding to the support frame 110. Among them, the wire arranging component is arranged above the wire winding shaft component. The wire winding shaft component includes a wire winding motor 131 and a wire storage wheel 132 fixed at the output end of the wire winding motor 131. The rotation of the wire winding motor 131 drives the forward and reverse rotation of the wire storage wheel 132, correspondingly driving the reciprocating movement of the cutting wire. The wire arranging component is correspondingly arranged above the wire storage wheel 132, which is convenient for the wire winding and turning wheel 130 fixed on the wire arranging component to move back and forth along the winding and unwinding path of the cutting wire.

[0071] Further, the wire arranging component includes a wire arranging motor 133 and a wire arranging linear module 134 fixed at the output end of the wire arranging motor 133. The wire winding and turning wheel 130 is fixed on the wire arranging linear module 134. The wire winding and turning wheel 130 moves back and forth on the wire arranging component through the linear module. The wire arranging motor 133 controls the movement direction and movement speed of the linear module. When in use, the output of the wire arranging motor 133 is set to match the wire winding motor 131, so that the cutting wire wound and unwound by the wire storage wheel 132 is always directly below the tangent direction of the wire winding and turning wheel 130.

[0072] Further, a weight balancing component 135 for balancing the wire arranging linear module 134 is provided on the wire arranging linear module 134. The weight balancing component 135 and the wire winding and turning wheel 130 are respectively arranged on both sides of the movable end of the wire arranging linear module 134. According to the lever principle, by adjusting the weight or the installation position of the weight balancing component 135, the wire turning wheel 130 can be basically kept vertically stable without being affected by external forces.

[0073] Further, the winding motor 131 is fixed on the winding mounting base 136, the winding mounting base 136 is fixed on the support frame 110, and a support rod 137 is provided on the winding mounting base 136 corresponding to the lower part of the wire storage wheel 132. The winding mounting base 136 is fixed inside the support frame 110, preferably an L-shaped winding mounting base 136, and a reinforcing rib plate is provided at the right-angle corner. The support rod 137 is arranged directly below the wire storage wheel 132 and extends along the axis direction of the wire storage wheel 132. Preferably, the length of the support rod 137 is longer than the length of the wire storage wheel 132. Two support rods 137 are arranged in parallel, and the distance between the two support rods 137 is smaller than the diameter of the wire storage wheel 132, ensuring that the wire storage wheel 132 is protected by the support rod 137 during disassembly, avoiding the phenomenon of slipping and rolling, and providing a temporary storage place for the wire storage wheel 132 for maintenance personnel during disassembly.

[0074] Further, it further includes a protective cover 160 arranged outside the support frame 110. The protective cover 160 is provided with inspection doors corresponding to the end of the main roller shaft 120, the tensioning assembly, the side of the cutting chamber 111 and / or the side of the winding chamber 112. The protective cover 160 covers the entire support frame 110, preventing the cutting chamber 111 and the winding chamber 112 inside the support frame 110 from being interfered by the outside. To save the floor area of the whole wire saw, the protective cover 160 is preferably designed to fit the structure of the support frame 110. Protective boxes are respectively protruded from the support frame 110 corresponding to each installation component on the support frame 110, and inspection doors that can be opened and closed separately are provided on the protective boxes corresponding to each installation component, facilitating the inspection and maintenance of each component at any time.

[0075] When the wire saw is in use, the cutting wire on the winding and arranging assembly on one side of the main roller shaft 120 is wound around the main roller shaft 120 after passing through the winding and arranging turning wheel 130, the tension turning wheel 150 and the main roller shaft turning wheel 140 in sequence, and then is conveyed to the winding and arranging assembly on the other side after passing through the main roller shaft turning wheel 140, the tension turning wheel 150 and the winding and arranging turning wheel 130 in sequence on the other side of the main roller shaft 120. After the cutting wire mesh is laid, the hard and brittle material is cut. The motor drives the main roller shaft 120 to rotate, and the cutting wire runs at a high speed back and forth on the main roller shaft 120 to cut the hard and brittle material. The tension sensor monitors the tension of the cutting wire in real time, and the tensioning assembly adjusts the angle of the tension arm 152 in real time according to the preset tension value to ensure the stable tension of the cutting wire.

[0076] The feeding mechanism is arranged on the top of the support frame 110 and is used to press the hard and brittle material towards the cutting wire mesh in the cutting area at a certain speed when cutting the hard and brittle material. It includes a feeding base, a feeding drive assembly arranged on the feeding base for providing sliding power, and a slide plate for fixing the sliding direction. The feeding drive assembly includes a feeding lead screw and a feeding nut. A support unit is arranged on the feeding lead screw, and the feeding drive assembly is fixed on the feeding base through the support unit. The feeding nut is connected to the slide plate through a nut seat. The feeding nut drives the slide plate to move up and down through the nut seat. A workpiece table assembly is also arranged at the bottom of the slide plate. The hard and brittle material is fixed at the bottom of the workpiece table assembly. When the slide plate moves downward, the workpiece table assembly drives the hard and brittle material to press towards the cutting wire mesh.

[0077] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention, and it cannot limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made according to the scope of this application should still fall within the scope covered by the present invention.
