Description

Technical Field

[0001] The present invention belongs to the technical field of wire cutting, and specifically provides a wire cutting machine and a control method thereof, a machine-readable storage medium, and a control device. Background Art

[0002] Wire cutting machine is a device that cuts cutting objects (such as magnetic materials, silicon rods, gemstones, etc.) through wire cutting process.

[0003] Existing wire cutting machines mainly include functional modules or assemblies such as the main roller assembly, feeding device, retractable wire control device, and spray device. The main roller assembly usually includes multiple parallel main rollers to arrange the cutting line. The feeding device is used to fix the cutting object and carry the cutting object toward the cutting line. The retractable wire control device is used to control the cutting speed, acceleration and deceleration, and wire tension of the cutting line. The spray device is used to spray cutting fluid (which can be cutting oil or water-based cutting fluid) onto the cutting line to cool the cutting line and the cutting object, as well as to take away the waste generated during the cutting process.

[0004] In some wire-cutting machines, the main roller assembly consists of four parallel rollers arranged in a top-down, bottom-down configuration. The cutting wire is wound around the outer edges of these rollers, forming a triangular web of wire. The center roller of the three lower rollers is slightly lower than the other two to ensure proper tension when the wire contacts the object being cut.

[0005] However, because the center roller is slightly lower than the two outer rollers, the side of the object closest to the center roller comes into contact with the cutting line first, and is cut by the cutting line first. This cutting method can easily lead to unstable sheet thickness at the time of entry, large sheet thickness tolerances, and a low yield rate. Summary of the Invention

[0006] One purpose of the present invention is to solve the problem in the prior art that the height of the middle main roller is slightly lower than that of the two outer main rollers, resulting in unstable thickness and large thickness tolerance when the cutting object is cut.

[0007] To achieve the above-mentioned object, the present invention provides, in a first aspect, a control method for a wire cutting machine, wherein the wire cutting machine includes a main roller assembly for arranging a cutting wire and a feeding device for fixing a cutting object; the control method includes:

[0008] Determining a cutting zero point of the cutting object;

[0009] Determining an initial position of the cutting object according to the cutting zero point, wherein the initial position is located on a side of the cutting zero point away from the cutting line;

[0010] controlling the wire cutting machine to operate the cutting wire;

[0011] Controlling the feeding device to move the cutting object from the initial position to the cutting line at a first feeding speed v1;

[0012] In response to the cutting object moving to the first target position, the feeding device is controlled to continue moving the cutting object at a second feeding speed v2; the first target position is located on the side of the cutting zero point away from the initial position, and v2 is greater than v1.

[0013] Optionally, the step of determining the cutting zero point of the cutting object includes:

[0014] When the cutting object moves to just contact with the cutting line, the current position of the cutting object is recorded as the cutting zero point.

[0015] Optionally, when the cutting object moves to just contact the cutting line, the step of recording the current position of the cutting object as the cutting zero point includes:

[0016] Obtaining the current tension of the cutting line;

[0017] When the current tension reaches a preset value, the current position of the cutting object is recorded as a cutting zero point.

[0018] Optionally, the distance between the initial position and the cutting zero point is recorded as D0, and the following relationship is satisfied between D0 and v1:

[0019] D0÷v1=t0

[0020] Wherein, t0 is selected from any value between 0.5 min and 3 min.

[0021] Optionally, the distance between the first target position and the cutting zero point is recorded as D1, and the following relationship is satisfied between D1 and v1:

[0022] D1÷v1=t1

[0023] Wherein, t1 is selected from any value between 5 min and 15 min.

[0024] Optionally, the control method further includes:

[0025] In response to the cutting object moving to the second target position, controlling the feeding device to continue moving the cutting object at a third feeding speed v3 until cutting is completed;

[0026] Among them, v1<v3<v2.

[0027] Optionally, v1:v2:v3=a:b:c

[0028] Wherein, a is selected from any value between 3 and 5, b is selected from any value between 8 and 10, and c is selected from any value between 6 and 8.

[0029] In a second aspect, the present invention provides a machine-readable storage medium having a machine-executable program stored thereon. When the machine-executable program is executed by a processor, the control method according to any one of the first aspects is implemented.

[0030] In a third aspect, the present invention provides a control device comprising a memory, a processor, and a machine executable program stored in the memory and running on the processor, and when the processor executes the machine executable program, it implements the control method according to any one of the first aspects.

[0031] In a fourth aspect, the present invention provides a wire cutting machine, comprising the control device described in the third aspect.

[0032] Based on the foregoing description, those skilled in the art will be able to understand that, in the aforementioned technical solution of the present invention, the feeding device is controlled to move the cutting object from the initial position to the cutting line at a first feeding speed v1, and when the cutting object moves to the first target position, the feeding device is controlled to continue to move the cutting object at a second feeding speed v2, so that the present invention can enable the wire cutting machine to slowly cut the cutting object, reduce the thickness tolerance of the cutting object, and improve the yield of the cutting object.

[0033] It will be understood by those skilled in the art that, since the objects to be cut by the wire cutting machine are mainly hard and brittle materials such as magnetic materials, silicon rods, and gemstones, the present invention reduces the speed of the cutting blade into the cutting object so that the cutting wire can fully cut the cutting object, effectively avoiding the large impact force exerted by the cutting wire on the cutting object, which may cause the cutting object to have broken edges or cracks. In particular, it overcomes the problem of broken edges and cracks that occur in the initial stage of contact between the cutting wire and the cutting object due to the small contact area between the cutting object and the cutting wire. Correspondingly, the tension of the cutting wire is also reduced, thereby increasing the service life of the cutting wire.

[0034] In addition, the slow cutting method of the present invention also helps to reduce the vibration generated during the cutting process of the cutting line, thereby improving the stability of the cutting line and reducing the surface roughness of the cutting object; at the same time, it also avoids the internal stress concentration and potential defects of the cutting object caused by rapid cutting.

[0035] Based on the above reasons, the slow entry method of the present invention, which "controls the feeding device to move the cutting object from the initial position to the cutting line at a first feeding speed v1, and when the cutting object moves to the first target position, controls the feeding device to continue moving the cutting object at a second feeding speed v2", is particularly suitable for hard and brittle materials that are very sensitive to cutting speed and cutting force, and can achieve high-quality cutting of hard and brittle materials, thereby ensuring the final cutting quality and yield of the cutting object.

[0036] Other beneficial effects of the present invention will be described in detail below in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand the improved purposes, features and advantages of the present invention.

[0049] like Figure 1 As shown, in some embodiments of the present invention, the wire cutting machine 100 includes a main roller assembly 110 , a cutting wire 120 , and a feeding device 130 for fixing a cutting object 200 .

[0050] The main roller assembly 110 is used to arrange the cutting line 120 .

[0051] Specifically, the main roller assembly 110 includes four parallel main rollers 111 , and the four main rollers 111 are distributed in the form of three on top and three on the bottom.

[0052] like Figure 2 As shown, in some embodiments of the present invention, each main roller 111 is provided with a plurality of roller grooves 1111 , and the cutting lines 120 are embedded in the roller grooves 1111 to ensure that the distance between two adjacent cutting lines 120 on the main roller 111 is stable.

[0053] Continue reading Figure 1 The cutting line 120 is wrapped around the outer sides of the four main rollers 111, forming a triangular shape and a web. The center of the three lower main rollers 111 is slightly lower than the other two to ensure proper tension when the cutting line 120 contacts the object 200.

[0054] like Figure 1 As shown, in some embodiments of the present invention, the feeding device 130 is located below the main roller assembly 110 and is configured to carry the cutting object 200 and move in a vertical direction to approach or move away from the main roller assembly 110, so that the cutting line 120 cuts the cutting object 200 and retracts after the cutting is completed.

[0055] In addition, in other embodiments of the present invention, those skilled in the art may also, as needed, mirror-image the main roller assembly 110 and the feeding device 130 relative to a certain horizontal plane, so that the feeding device 130 is located above the main roller assembly 110.

[0056] Continue reading Figure 1 In some embodiments of the present invention, the feeding device 130 includes a base 131, a workbench 132 that can move up and down relative to the base 131, and a driving device (not marked or shown in the figure) that drives the workbench 132 to move.

[0057] Optionally, a slide rail extending in a vertical direction is provided on the base 131, and the workbench 132 is slidably connected to the slide rail so that the workbench 132 moves up and down along the slide rail. It will be understood by those skilled in the art that the slide rail can enable the workbench 132 to move up and down stably and prevent the workbench 132 from shaking.

[0058] Further optionally, the driving device includes a motor and a screw-nut transmission structure (or a gear rack transmission structure), and the motor is fixedly mounted on the base 131. The motor is connected to the workbench 132 through the screw-nut transmission structure (or the gear rack transmission structure), so as to drive the workbench 132 to move through the screw-nut transmission structure (or the gear rack transmission structure).

[0059] like Figure 1 As shown, in some embodiments of the present invention, when the wire cutting machine 100 is in use, the cutting object 200 is fixed to the workbench 132 .

[0060] Furthermore, the cutting object 200 can be fixed to the workbench 132 by bonding, clamping, or other fixing methods.

[0061] For example, the cutting object 200 can be bonded to the workbench 132 by 502 type glue. Further, in order to prevent the cutting line 120 from cutting the workbench 132, a marble slab can be fixed on the workbench 132 (for example, by bonding with 502 type glue), and then the cutting object 200 is fixed on the marble slab.

[0062] In the present invention, the cutting object 200 can be any feasible material such as magnetic material, silicon rod, gemstone, etc.

[0063] Furthermore, the cutting wire 120 may be a diamond wire or any other feasible cutting wire, and the diameter of the cutting wire 120 may be selected from any value between 120 μm and 200 μm, for example, 120 μm, 160 μm, 190 μm, 200 μm, etc.

[0064] In addition, although not shown in the figure, the wire cutting machine 100 of the present invention may also include a wire retracting and releasing control device, a spraying device and other functional modules or assemblies. Figure 1 Other structures of the wire cutting machine 100 not shown in the figure are not directly related to the purpose of the invention and are well known to those skilled in the art, so they will not be described in detail in the present invention.

[0065] like Figure 3 As shown, in some embodiments of the present invention, the wire cutting machine 100 may further include a control device 140, which includes a processor 141, a memory 142, and a machine executable program 1421 stored in the memory 142 and running on the processor 141, and when the processor 141 executes the machine executable program 1421, it implements the control method described in any of the following embodiments.

[0066] The processor 141 is an integrated circuit chip capable of processing signals. The processor 141 can be a general-purpose processor, such as a central processing unit (CPU), a network processor (NP), a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, a microprocessor, or any other conventional processor.

[0067] In this embodiment, the memory 142 may include a memory and a non-volatile memory, and provides execution instructions and data to the processor 141. For example, the memory may be a high-speed random-access memory (RAM), and the non-volatile memory may be at least one disk storage.

[0068] In addition, in other embodiments of the present invention, those skilled in the art may also configure the control device 140 as a device independent of the wire cutting machine 100, such as a computer, as needed. Then, the control device 140 is connected to the wire cutting machine 100 through a control system, so that the control device 140 controls the wire cutting machine 100 to execute the control method described in any of the following embodiments.

[0069] Refer to the following Figures 4 to 6 The control method of the wire cutting machine 100 in other embodiments of the present invention will be described in detail.

[0070] like Figure 4 As shown, in some embodiments of the present invention, the control method of the wire cutting machine 100 includes:

[0071] Step S100 , determining a cutting zero point 01 of the cutting object 200 to determine a cutting position of the cutting line 120 relative to the cutting object 200 .

[0072] Step S200 , determining an initial position 02 of the cutting object 200 according to the cutting zero point 01 , where the initial position 02 is located on a side of the cutting zero point 01 away from the cutting line 120 .

[0073] In step S300 , the wire saw 100 is controlled to operate the cutting wire 120 .

[0074] In step S400 , the feeding device 130 is controlled to move the cutting object 200 from the initial position 02 toward the cutting line 120 at a first feeding speed v1 , so that the cutting object 200 slowly approaches the cutting line 120 .

[0075] In step S500, in response to the cutting object 200 moving to the first target position 03, the feed device 130 is controlled to continue moving the cutting object 200 at a second feed speed v2; the first target position 03 is located on the side of the cutting zero point 01 away from the initial position 02, and v2 is greater than v1. Those skilled in the art will appreciate that by making v2 greater than v1, the wire cutting machine 100 of the present invention can quickly form a wire bow and cutting force on the cutting wire 120 after completing the pre-cutting of the cutting object 200, thereby ensuring the cutting quality of the cutting wire 120 on the cutting object 200 and the stability of the cutting process.

[0076] In optional step S600, in response to the object 200 moving to the second target position 04, the feed device 130 is controlled to continue moving the object 200 at a third feed speed v3 until the cutting is completed. Here, v1 < v3 < v2. Those skilled in the art will appreciate that by ensuring v3 < v2, the cutting line 120 can cut the object 200 at a stable feed speed, thereby ensuring the cutting quality of the object 200 and the stability of the cutting process.

[0077] Those skilled in the art will appreciate that, in other embodiments of the present invention, by controlling the feeding device 130 to move the cutting object 200 from the initial position 02 to the cutting line 120 at a first feeding speed v1, and when the cutting object 200 moves to the first target position 03, the feeding device 130 is controlled to continue moving the cutting object 200 at a second feeding speed v2, so that the present invention enables the wire cutting machine 100 to slowly cut the cutting object 200, thereby reducing the sheet thickness tolerance of the cutting object 200 and improving the yield of the cutting object 200.

[0078] Step S100 may specifically include: when the cutting object 200 moves to just contact the cutting line 120, recording the current position of the cutting object 200 as the cutting zero point 01. This step can be manually determined by an operator by observing the contact between the cutting object 200 and the cutting line 120. This can also be determined by detecting changes in the tension of the cutting line 120.

[0079] For example, Figure 5 As shown, step S100 may further include:

[0080] Step S110 , obtaining the current tension of the cutting wire 120 . Specifically, the wire cutting machine 100 may be equipped with a sensor for detecting the tension of the cutting wire 120 , so that the current tension of the cutting wire 120 is detected by the sensor.

[0081] Step S120 : When the current tension reaches a preset value, the current position of the cutting object 200 is recorded as the cutting zero point 01 .

[0082] The preset value may be any feasible value.

[0083] For example, the tension of the cutting line 120 is detected before the cutting object 200 comes into contact with the cutting line 120. For ease of description, the tension at this point is referred to as the normal tension. When the cutting object 200 comes into contact with the cutting line 120, the detected tension of the cutting line 120 suddenly increases, and the ratio of the detected tension to the normal tension exceeds m% (i.e., a preset value). m is a value greater than 100, for example, m can be any feasible value such as 105, 110, 120, 130, or the like.

[0084] The initial position 02 in step S200 can be determined by the following strategy:

[0085] like Figure 6 As shown, the distance between the initial position 02 and the cutting zero point 01 is recorded as D0, and the following relationship is satisfied between D0 and v1:

[0086] D0÷v1=t0 formula (1)

[0087] Wherein, t0 is selected from any value between 0.5 min and 3 min, for example, t0 may be 0.5 min, 1.8 min, 2.2 min, 2.5 min, 3 min, etc. In one example of the present invention, t0 may be 2.5 min.

[0088] The first feed speed v1 is selected from any value between 150 μm / min and 250 μm / min, for example, 150 μm / min, 180 μm / min, 190 μm / min, 230 μm / min, 250 μm / min, etc. In one example of the present invention, the first feed speed v1 may be 200 μm / min.

[0089] Those skilled in the art will understand that, when the cutting zero point 01, the direction of the initial position 02 relative to the cutting zero point 01, the first feed speed v1 and t0 are known, the position of the initial position 02 can be determined by formula (1).

[0090] Furthermore, after the initial position 02 is determined, the control method further includes a step between step S200 and step S400 : controlling the feeding device 130 to move the cutting object 200 to the initial position 02 .

[0091] Step S300 may further include controlling the wire saw 100 to allow the cutting wire 120 to run in a reciprocating manner.

[0092] In other words, the wire cutting machine 100 is controlled to make the cutting line 120 advance a distance and then retreat a distance. Each time the cutting line 120 advances a distance and retreats a distance constitutes a cycle, and this cycle is repeated, so that the cutting line 120 runs in a reciprocating manner.

[0093] The cutting line 120 advances a distance greater than the retreat distance, so that new cutting lines 120 are continuously introduced to prevent the cutting quality of the cutting object 200 from being reduced when the cutting line 120 is used for a long time.

[0094] Step S300 may further include: controlling the wire saw 100 to control the speed of the cutting wire 120 to be between 10 m / min and 30 m / min.

[0095] For example, the line speed of the cutting line 120 is controlled to be 10 m / min, 15 m / min, 22 m / min, 28 m / min, 30 m / min, etc.

[0096] The first target position 03 in step S500 can be determined by the following strategy:

[0097] like Figure 6 As shown, the distance between the first target position 03 and the cutting zero point 01 is recorded as D1, and the following relationship is satisfied between D1 and v1:

[0098] D1÷v1=t1 Formula (2)

[0099] Wherein, t1 is selected from any value between 5 min and 15 min. For example, t1 can be 5 min, 8 min, 12 min, 15 min, etc. In one example of the present invention, t1 can be 10 min.

[0100] Those skilled in the art will understand that, when the cutting zero point 01, the direction of the first target position 03 relative to the cutting zero point 01, the first feed speed v1 and t1 are known, the position of the first target position 03 can be determined by formula (2).

[0101] Furthermore, the second feed speed v2 in step S500 is selected from any value between 400 μm / min and 500 μm / min, for example, 400 μm / min, 420 μm / min, 450 μm / min, 490 μm / min, 500 μm / min, etc. In one example of the present invention, the second feed speed v2 may be 450 μm / min.

[0102] The first target position 03 in step S600 can be determined by the following strategy:

[0103] like Figure 6 As shown, the distance between the second target position 04 and the first target position 03 is recorded as D2, and the following relationship is satisfied between D2 and v2:

[0104] D2÷v2=t2 Formula (3)

[0105] Wherein, t2 is selected from any value between 35 min and 75 min. For example, t2 can be 35 min, 40 min, 50 min, 55 min, 75 min, etc. In one example of the present invention, t2 can be 55 min.

[0106] Those skilled in the art will appreciate that, when the moving direction of the cutting device, the second feed speed v2 and t2 are known, the position of the second target position O4 can be determined by formula (3).

[0107] Furthermore, the third feed speed v3 in step S600 is selected from any value between 300 μm / min and 400 μm / min, for example, 300 μm / min, 320 μm / min, 350 μm / min, 390 μm / min, 400 μm / min, etc. In one example of the present invention, the third feed speed v3 may be 350 μm / min.

[0108] In addition, in other embodiments of the present invention, those skilled in the art may also determine the second target position 04 in other ways as needed. For example, the second target position 04 may be determined according to the thickness of the cutting object 200 .

[0109] For example, the distance between the second target position 04 and the cutting zero point 01 is made smaller by a set value than the thickness of the cutting object 200. The set value can be any feasible value such as 1 mm, 2 mm, 3 mm, etc.

[0110] Furthermore, in some other embodiments of the present invention, the first feed speed v1, the second feed speed v2 and the third feed speed v3 satisfy the following relationship:

[0111] v1:v2:v3=a:b:c Formula (4)

[0112] Wherein, a is selected from any value between 3 and 5, b is selected from any value between 8 and 10, and c is selected from any value between 6 and 8.

[0113] In one example of the present invention, v1:v2:v3=a:b:c=4:9:7, and v1=200 μm / min, v2=450 μm / min, and v3=350 μm / min.

[0114] So far, the control method of the wire cutting machine 100 of the present invention has been described with reference to the accompanying drawings and in combination with the above embodiments.

[0115] It should be noted that although the control method of the present invention is combined Figure 1 The wire cutting machine 100 shown in FIG is described in detail, but the control method of the present invention is not limited to Figure 1 The wire cutting machine 100 shown in FIG. 1 may be applicable to any other feasible wire cutting machine 100, such as a double-roller wire cutting machine 100, a triple-roller wire cutting machine 100, and the like.
