Description

Technical Field

[0001] The present disclosure relates to the field of wire cutting, and in particular to a three-beam four-column structure, a wire mesh cutting device and a wire mesh cutting method. Background Art

[0002] In the process of cutting silicon rods into square silicon cores, the cutting wire is generally wound around the guide wheel group of the equipment to form a cutting wire array. The mutually orthogonal cutting wire arrays formed by the two guide wheel groups form a wire net, and the square mesh of the wire net is used to achieve square silicon core cutting. With the rapid development of the integrated circuit industry, the demand for triangular silicon cores is increasing. However, due to the complex loads applied by the silicon rods during the cutting operation, slight deformation or vibration will affect the cutting quality of the silicon core. Therefore, there is no wire net cutting equipment in the prior art that can batch cut triangular silicon cores. Summary of the invention

[0003] The present invention provides a wire mesh cutting device and a wire mesh cutting method.

[0004] Specifically, the present disclosure is achieved through the following technical solutions: In the first aspect, the embodiments of the present disclosure provide a three-beam and four-column structure, which is used on a wire mesh cutting device, wherein the wire mesh cutting device is used to cut a rod into multiple core materials, and the rod is fixed on a frame of the wire mesh cutting device; the three-beam and four-column structure includes: a top seat, which is arranged on the frame and is located at the upper part; a base, which is arranged on the frame and is located at the lower part; a tool table, which is located on the frame between the top seat and the base; the tool table includes a base; a guide column assembly, which is arranged on the frame, and the guide column assembly includes a plurality of guide columns arranged in a polygonal shape, each of which is transmission-connected to the tool table; the top seat, the base that moves along the axial direction of the rod with the tool table, and the base form a horizontal three-beam structure, and the plurality of guide columns on the guide column assembly form a vertical multi-column structure.

[0005] In some embodiments, the number of guide pillars on the guide pillar assembly is four, and the four guide pillars form a vertical four-pillar structure, which together with the three-beam structure constitute a three-beam four-pillar structure for cutting rods.

[0006] The structure has three beams and four columns, and the knife platform is placed in the middle of the four columns. That is, the center of gravity of the knife platform is in the middle of the four columns, which makes the center of gravity more stable and better able to bear force.

[0007] In a first aspect, an embodiment of the present disclosure provides a wire mesh cutting device for cutting a rod into a plurality of core materials, the wire mesh cutting device comprising: a frame for fixing the rod; a tool table arranged on the frame and capable of moving axially along the rod relative to the frame; a guide wheel mechanism arranged on the tool table and capable of moving with the tool table, wherein the guide wheel mechanism is provided with a plurality of guide wheel groups, each guide wheel group being wound with a cutting line array with a consistent trajectory, the trajectories of the cutting line arrays wound on the plurality of guide wheel groups intersecting with each other, so that the mesh of the formed cutting wire mesh is an equilateral polygon.

[0008] According to the disclosed embodiment, three beams of cutting line tracks intersect each other so that the formed cutting wire net has an array of equilateral triangle meshes, and the three sides of each mesh are respectively composed of three different beams of cutting line tracks. When the tool table drives the guide wheel mechanism to feed the cutting operation, the load applied by the bar stock is shared by the three different beams of cutting line tracks. While quickly cutting the bar stock into triangular core materials, it can also provide stable bearing for the load applied by the bar stock, thereby preventing the wire net from deforming or vibrating and affecting the cutting quality.

[0009] In some embodiments, the number of the guide wheel groups is three, which are distributed in an equilateral triangle; the cutting line trajectories wound on the three guide wheel groups cross each other and form an angle of 120 degrees between each other, so that the mesh of the formed cutting line network is an equilateral triangle; each guide wheel group is provided with at least one pair of guide wheels opposed to each other, so that the three pairs of guide wheels of the three guide wheel groups are arranged at an equal angle of 60 degrees along the circumferential direction.

[0010] In some embodiments, it also includes: a wire supply mechanism, used to distribute at least two independent cutting wires to three guide wheel groups, wherein at least one cutting wire is only distributed to one guide wheel group; if the three cutting wire arrays are all from the same cutting wire, the loads borne by the three cutting wire arrays are all concentrated on the same cutting wire, which is prone to wire breakage or the cutting wire being stretched and plastically deformed. This embodiment avoids this problem.

[0011] In one embodiment, the wire supply mechanism distributes two independent cutting lines to three guide wheel groups, wherein one cutting line is distributed to one guide wheel group, and the other cutting line is distributed to the other two guide wheel groups. In the cutting line network, the cutting line column formed by the guide wheel group to which one cutting line is separately distributed is located between the cutting line columns formed by the other two guide wheel groups. The cutting line column formed by the guide wheel group to which one cutting line is separately distributed has a higher load-bearing capacity. It is set in the middle position. During the process of advancing and retracting along the axial z direction, it can provide additional support to the upper and lower cutting line columns respectively, thereby further improving the stability of the wire network.

[0012] In some embodiments, two circumferentially adjacent guide wheels among the three pairs of guide wheels are arranged symmetrically toward one side of the frame, and serve as wire inlet guide wheels of their respective guide wheel groups, respectively receiving two independent cutting wires supplied by a wire supply mechanism arranged on the same side of the frame, so that the cutting wire provided by the wire supply mechanism reaches the guide wheel mechanism through the shortest path, thereby improving the utilization rate of the cutting wire and avoiding the problem of a decrease in cutting tension due to excessive relaxation of the cutting wire between the wire supply mechanism and the guide wheel mechanism.

[0013] In some embodiments, the frame is provided with a top seat and a base, the tool table is provided with a base, and three pairs of guide wheels are symmetrically arranged on both sides of the base relative to a first center line x1 extending forward and backward. The wire mesh cutting equipment also includes: a driving mechanism, which is arranged between the top seat and the base and connected to the base, and is used to drive the tool table to move along the axial direction z; a guiding mechanism, which is provided with four guide columns and is all connected to the base, and is used to guide the tool table to move along the axial direction z; wherein, the first driving point connected between the driving mechanism and the base is located at the rear side of the three pairs of guide wheels on the first center line x1, the first guide points connected between the two guide columns and the base are symmetrically arranged at the front side of the three pairs of guide wheels relative to the first center line x1, and the first guide points connected between the other two guide columns and the base are symmetrically arranged at the rear side of the driving points relative to the first center line x1, and the spacing between the two first guide points in the front is greater than the spacing between the two first guide points in the back. Through the position layout of the first driving point and the first guide point, the larger load applied to the bar material is balanced to ensure the stability of the cutting wire mesh.

[0014] In some embodiments, the top seat is configured to have a "Y" shape with a second center line x2, the "Y" shape opening faces forward and the bottom of the opening is opposite to the cutting wire mesh position, the second driving point connected between the driving mechanism and the top seat is located behind the "Y" shape of the second center line x2, the second guide points connected between the two guide columns and the top seat are symmetrically arranged relative to the second center line x2, and the second driving point of the "Y" shape is behind, and the other two second guide points connected between the two guide columns and the top seat are symmetrically arranged at the front end of the "Y"-shaped fork relative to the second center line x2. Through the "Y"-shaped structural design of the top seat and the position layout of the second driving point and the second guide point, the structural strength of the top seat is improved, thereby ensuring the structural stability of the driving mechanism and the guide mechanism.

[0015] In some embodiments, a counterweight mechanism is also included, which is provided with a weight block, four pulleys and two pull ropes, wherein two pulleys are symmetrically arranged on the inner side of two second guide points at the front end of the "Y"-shaped fork relative to the second center line x2, and the other two pulleys are symmetrically arranged at the rear end of the "Y" shape with respect to the second center line x2, and the distance between the two pulleys at the front end is greater than the distance between the two pulleys at the rear end, wherein the pull ropes are connected to the tool table and the weight block at the front and rear sides respectively, and the position arrangement of the four pulleys allows the top seat to maintain structural stability under the load of the counterweight mechanism.

[0016] In some embodiments, a through hole is provided between the second guide point at the front end and the second guide point at the rear of the top seat, and the through hole is aligned with the second guide point at the rear in the direction of the second center line x2. The through hole allows circuits and water pipelines to pass through the top seat, and the position of the through hole will not affect the structural strength of the top seat.

[0017] In some embodiments, a closed first rib is provided on the outer periphery of the top seat, and a second rib is provided between the through hole and the second guide point at the front end, the second guide point at the rear, the opening and the first ribs on both sides. The structural strength of the top seat is further improved by the distribution of the first rib and the second rib.

[0018] In a second aspect, an embodiment of the present disclosure provides a wire mesh cutting method for cutting a bar into a plurality of triangular core materials, the wire mesh cutting method comprising: Three guide wheel groups are arranged on the knife table, and a cutting line array with the same trajectory is wound on each guide wheel group. The cutting line array trajectories wound on the three guide wheel groups intersect with each other and form an angle of 120 degrees between each other, so that the mesh of the formed cutting line net is an equilateral triangle; The driving knife table drives the cutting wire net to move axially along the bar material, thereby cutting the bar material into a plurality of triangular core materials.

It should be understood that these numerical values ​​and numerical ranges are merely exemplary, which may be helpful in putting the idea of ​​the present disclosure into practice. However, the description of these examples is not intended to limit the scope of the present disclosure in any way. According to specific application scenarios and requirements, these numerical values ​​or numerical ranges can be set separately.

[0026] As mentioned above, the wire mesh cutting equipment in the prior art cannot cut triangular silicon cores in batches. The wire mesh cutting equipment and wire mesh cutting method proposed in the embodiments of the present disclosure at least partially solve the above problems. Figures 1 to 8 The structure and working principle of the wire mesh cutting device and the wire mesh cutting method according to the exemplary embodiments of the present disclosure are described.

[0027] like Figure 1 As shown, the wire mesh cutting equipment of the embodiment of the present disclosure and the three-beam and four-column structure designed thereon.

[0028] The wire mesh cutting equipment generally includes a frame 10, a tool table 20, a guide wheel mechanism 30, a wire supply mechanism (not shown in the figure) and a counterweight mechanism, wherein the frame 10 is used to carry the rod material, the tool table 20, the guide wheel mechanism 30 and the counterweight mechanism, the tool table 20 is used to drive the guide wheel to move along the axial direction z of the rod material, the guide wheel mechanism 30 is used to wind the cutting wire 01 and construct a cutting wire net, the counterweight mechanism is used to ensure the stable movement of the tool table 20 and the guide wheel mechanism 30, and the wire supply mechanism is used to provide the cutting wire 01 for the guide wheel mechanism 30.

[0029] The guide wheel mechanism 30 is provided with a plurality of guide wheel groups, each of which is wound with a cutting line array with a consistent trajectory, and the cutting line array trajectories wound on the plurality of guide wheel groups intersect with each other, so that the mesh of the formed cutting line net is an equilateral polygon. From the above structural description, it can be concluded that the equilateral polygon is for the cut polygonal core material. The core material can be a quadrangle, a pentagon or other polygon.

[0030] It is important to note that the three-beam four-column structure includes a top seat, a base and a pedestal. The top seat 11 is arranged on the upper part of the frame 10, the base is arranged on the lower part of the frame, the knife platform is located on the frame between the top seat and the base, and the knife platform includes a pedestal.

[0031] The guide column assembly is arranged on the frame, and includes a plurality of guide columns arranged in a polygonal shape, each guide column is connected to the tool table in a transmission manner, so that the tool table can move along the axial direction (z) of the bar material on the guide column assembly. This structure is designed for triangular core materials, so the number of guide columns is four.

[0032] From the above description, it can be known that the top seat 11, the platform 21 that moves along the axial direction (z) of the bar with the tool table, and the base 12 form a horizontal three-beam structure, and the four guide columns on the guide column assembly form a vertical four-column structure.

[0033] The structure has three beams and four columns, and the knife platform is placed in the middle of the four columns. That is, the center of gravity of the knife platform is in the middle of the four columns, which makes the center of gravity more stable and better able to bear force.

[0034] This embodiment is designed for a triangular core material.

[0035] The frame 10 is composed of a top seat 11 and a base 12, which are fixed to each other by a connecting structure (the connecting structure is not shown in the figure). The top seat 11 suspends the driving mechanism, the guide mechanism and the bar from the top, and the base 12 supports the driving mechanism, the guide mechanism and the bar from the bottom, so that the driving mechanism, the guide mechanism and the bar can remain stable, thereby ensuring the cutting accuracy of the bar.

[0036] In one embodiment, the guide mechanism may be in the form of a guide column or a guide rail. Exemplarily, the number of guide columns may be two, three or four. Preferably, four guide columns arranged front and back can provide stable guiding and load-bearing functions for the tool holder 20.

[0037] In one embodiment, the four guide posts are all disposed on the base 21 of the tool platform 20, so that the tool platform 20 can move freely along the length direction of the guide posts (the axial direction z of the bar). Figure 4 and 5 As shown, four half-bearings 211 are arranged in front and rear of the base 21, two front guide columns 41 are penetrated in the half-bearings 211 at the front of the base 21 and are threadedly connected, and two rear guide columns 42 are penetrated in the half-bearings 211 at the rear of the base 21 and are threadedly connected. In order to clearly explain the bearing effect of the front guide columns 41 and the rear guide columns 42 on the tool platform 20, the bearing position of the guide column on the tool platform 20 is planned to be the center point of the guide column cross-sectional shape, that is, the bearing force distribution position provided by the front guide columns 41 and the rear guide columns 42 on the tool platform 20 is four first guide points s1, and the distance L1 between the two first guide points corresponding to the front guide column 41 is greater than the distance L2 between the two first guide points corresponding to the rear guide column 42.

[0038] In addition, in the previous technology, four full-circle bearings are arranged in front and behind the base 21. This connection method has certain limitations, that is, when the bearing is worn and needs to be replaced, the top base 11 can only be removed to remove the full-circle bearing, which is acceptable for equipment with smaller sizes, but for the equipment of the present invention, the vertical stroke usually reaches 3-4 meters, and the full-circle bearing structure is very unchanged in maintenance. Therefore, the equipment of the present invention adopts a semi-bearing structure, and the tool table matched with the semi-bearing also adopts a semi-circular method. When the bearing is worn, the semi-bearing can be easily removed from the guide column.

[0039] In one embodiment, the driving mechanism can be in a telescopic form, such as a cylinder or a hydraulic cylinder, or in a threaded form, such as a screw 43 nut pair, preferably in a threaded form. Specifically, the driver is arranged on the top seat 11, and the output shaft of the driver is connected to the screw 43, and the screw 43 extends between the top seat 11 and the base 12, and the extension direction is consistent with the front guide column 41, the rear guide column 42 and the bar axial direction z.

[0040] In one embodiment, the screw rod 43 cooperates with a nut provided on the base 21, so that when the screw rod 43 is driven to rotate by the driver, the tool stage 20 can be driven to move upward or downward. In order to clearly explain the force between the screw rod 43 and the tool stage 20, the force application position of the screw rod 43 on the tool stage 20 is proposed to be the center point of the cross-sectional shape of the screw rod 43, that is, the force application position provided by the screw rod 43 on the tool stage 20 is the first driving point m1, and the first driving point m1 is located at the rear of the base 21 in the front-to-back direction and close to the two second guide points s1 of the rear guide column 42.

[0041] During the cutting operation, the load applied by the bar to the cutting wire net can be set as the guide wheel center o, that is, the bar applies a load downward (toward the base 12) at the guide wheel center o, the screw rod 43 provides an upward (toward the top seat 11) bearing force to the tool table 20 at the first driving point m1, and the rear guide column 42 can also provide a certain bearing force to the tool table 20 at the corresponding first guide point s1 (using the contact force between the outer wall of the guide column and the inner wall of the half bearing 211), so that the tool table 20 is balanced on the left and right sides relative to the first center line x1 to prevent overturning. Since the rear guide column 42 is located close to the first driving point m1, it is only necessary to set the distance between the two rear guide columns 42 to be close to meet the upward bearing force requirements, while saving space on the left and right sides.

[0042] On the one hand, since three guide wheel groups are provided, the size of the guide wheel mechanism 30 in the front-to-back direction is increased, and therefore the position of the front guide column 41 is set at the front of the pedestal 21 rather than the front end, so as to avoid the problem of the front and rear span being too large due to the front guide column 41 being set at the front end of the pedestal 21, causing the pedestal 21 to bend and deform downward.

[0043] On the other hand, since three guide wheel groups are used for cutting, the load of the bar forms load components in three directions. Figure 5 As shown, the load forms load components in the six guide wheel directions, among which the load components of the two guide wheels in the left front direction can be combined into F1. The theoretical direction of F1 is from the guide wheel center o to the center position between the two left front guide wheels. The spacing L1 between the first guide points s1 of the front guide column 41 is set to be greater than L2. The purpose is to enable the front guide column 41 to provide a bearing force from the first guide point s1 to the guide wheel center o to the tool holder 20 to offset F1. In fact, as long as the direction of the offsetting force can cover the two left front guide wheels, it is not strictly required that the direction must be located at the center position between the two guide wheels. In other words, the offsetting force only needs to be within the angle range between the two directions f1 in the figure. Similarly, the load components of the two right front guide wheels are combined into F1, and the two load components F2 of the rear guide column 42 are applicable to the aforementioned principle. In addition, the arrangement of the four guide columns can also be Figure 5 The knife table 20 is prevented from rotating on the plane shown. Figure 8 As shown, the tool holder according to the embodiment of the present disclosure can meet the structural strength requirements.

[0044] In one embodiment, Figure 2 and 3As shown, the driver connected to the lead screw 43 is arranged on the top seat 11. The center of the cross-sectional shape of the lead screw 43 is defined as the second driving point m2. The front guide post 41 and the rear guide post 42 are respectively connected to the front end and the rear position of the top seat 11. The centers of the cross-sections of the front guide post 41 and the rear guide post 42 are defined as the second guiding points s2. Among them, the top seat 11 bears the downward load force of the lead screw 43 at the second driving point m2, and the top seat 11 mainly bears the bearing force applied upward by the guide post at the second guiding point s2. The area of the top seat 11 does not need to be too large, as long as there is enough space for installing components.

[0045] In one embodiment, the top seat 11 is integrally set in a "Y" shape because there is no need to install components between the second guiding points s2 corresponding to the front guide post 41. At the same time, an opening 13 is formed at the front end of the "Y" shape for placing the bar through the opening 13 and hoisting it to the bottom of the opening 13.

[0046] In one embodiment, a pair of pull ropes 143 are respectively connected to the weight 141 and the tool post 20 to make the movement of the tool post 20 more stable and prevent the tool post 20 from quickly descending under the action of gravity. Four pulleys 142 are symmetrically arranged at the front end and the rear end of the top seat 11 relative to the second center line x2 respectively, and the pulleys 142 apply a downward load force to the top seat 11. Preferably, in order to make the weight 141 occupy less space in the left and right directions, the size of the weight 141 is set to be narrow, and the connection positions of the pair of pull ropes 143 on the weight 141 are close. In another embodiment, since the size of the tool post 20 in the left and right directions has been determined (determined by the cross-sectional size of the bar stock), and due to the "Y" - shaped structural design of the top seat 11, the front pulley 142 is arranged between the two second guiding points s2 and close to the second guiding point s2, which not only ensures that the pull rope 143 tightly pulls the tool post 20 smoothly but also further makes full use of the "Y" - shaped structural space of the top seat 11.

[0047] In one embodiment, for the cutting operation, it is necessary to connect the circuit and water pipeline. To facilitate pipe routing and at the same time ensure the structural strength of the top seat 11, two through - holes 15 are opened on both sides of the middle of the top seat 11. The through - holes 15 are located at the junction between the bifurcated part and the "|" - shaped part of the "Y" shape and are aligned with the second guiding point s2 corresponding to the rear guide post 42, so as to ensure that the through - holes 15 have almost no impact on the overall structural strength of the top seat 11.

[0048] In one embodiment, to further increase the structural strength of the top seat 11, a first rib 16 extending upward is formed on the outer peripheral edge of the top seat 11. Second ribs 17 are formed simultaneously between the through - hole 15 positions, between the second guiding points s2, and between the through - hole 15 positions, the second guiding points s2 and the first rib 16. As Figure 7 shown, using the top seat 11 of the embodiment of the present disclosure can meet the requirements of structural strength.

[0049] The guide wheel mechanism 30 is provided with three guide wheel groups, each of which is used to form a cutting line in one direction. Figure 4 and 5 As shown, each guide wheel group may include only a pair of mutually opposed main guide wheels 31, or may also include a pair of mutually opposed auxiliary guide wheels 32. The cutting line 01 is reciprocated around the pair of main guide wheels 31 and / or auxiliary guide wheels 32 to form a cutting line array that basically points in one direction. The six main guide wheels 31 and / or auxiliary guide wheels 32 are evenly arranged along the circumferential direction at 60 degrees, thereby forming a three-beam cutting line array that crosses at 120 degrees. The spacing between the cutting lines 01 of the cutting line array should be equal, as shown in FIG. Figure 6 As shown, a cutting wire network with equilateral triangle meshes is constructed.

[0050] In one embodiment, the three cutting wires may come from three independent cutting wires 01, so that each cutting wire has sufficient cutting tension. In another embodiment, the three cutting wires may come from one cutting wire 01, so that only one wire supply mechanism is required, saving space.

[0051] However, in order to strike a balance between cutting tension and space saving, it is preferred to set up two sets of wire supply mechanisms, with one cutting wire 01 only supplying one bundle of cutting wires, and the other cutting wire 01 supplying the remaining two bundles of cutting wires. In this way, the winding length of one cutting wire 01 in the two bundles of cutting wires can also meet the strength required for the rod load and maintain sufficient cutting tension.

[0052] In one embodiment, since two bundles of cutting wires that share a cutting wire 01 will experience a more obvious drop in cutting tension after being used for a period of time, in order to alleviate this problem, the two bundles of cutting wires are arranged above and below the cutting wire network, and the cutting wires that use a single cutting wire 01 are sandwiched between the two. When the tool table 20 rises to cut the bar, the middle layer of the cutting wire 01 bundle provides supplementary support for the upper layer of the cutting wire 01 bundle; when the tool table 20 descends to exit the bar, the middle layer of the cutting wire 01 bundle provides supplementary support for the lower layer of the cutting wire 01 bundle.

[0053] The cutting mechanism includes a wire supply wheel and a wire take-up wheel, and the guide wheels of each guide wheel group are provided with a wire feed wheel and a wire outlet wheel, wherein the wire feed wheel and the outlet wheel can be the same guide wheel, or different guide wheels in a pair of guide wheels. The cutting line 01 is sent from the wire supply wheel to the wire feed wheel, and then sent back from the outlet wheel to the rear wire wheel after forming a cutting line train. If the distance between the wire supply wheel and the wire feed wheel is too long, the cutting line 01 will be loosened, thereby affecting the cutting tension of the cutting wire net. In one embodiment, two circumferentially adjacent guide wheels of the three pairs of guide wheels are arranged symmetrically toward one side of the frame 10, and serve as the wire feed guide wheels of their respective guide wheel groups, respectively receiving two independent cutting wires supplied from the wire supply mechanism arranged on the same side of the frame 10. For example, as Figure 4 and 5 As shown, three pairs of guide wheels (six guide wheels, each guide wheel here includes a driving wheel and / or an auxiliary guide wheel 32) are defined as a, b, c, d, e, and f respectively, so that guide wheels a and b are symmetrically arranged relative to the first center line x1 and face the rear side of the frame 10, and guide wheels a and b are used as driving wheels. The specific winding method of the cutting line 01 is as follows: the cutting line 01 on the left side of the figure is first fed into the guide wheel b, and then sent back to the left wire-receiving wheel through the guide wheel e, thereby forming a bundle of cutting line trains. The cutting line 01 on the right side of the figure is first fed into the guide wheel a, and then sent to, for example, the guide wheel c after passing through the guide wheel d and the steering wheel, and then sent back to the right wire-receiving wheel through the guide wheel f, thereby forming two bundles of cutting line trains.

[0054] By using the wire mesh cutting device of the embodiment of the present disclosure, the tool table 20 is driven to drive the cutting wire mesh to move along the axial direction z of the bar material, thereby cutting the bar material into multiple triangular core materials, thereby achieving high-precision batch cutting operations of the triangular core materials.

[0055] It should be noted that the rod material in the embodiment of the present disclosure may be a silicon rod or a rod material of other materials.
