Detailed Implementation Modes

[0051] The present invention will be further described below in conjunction with specific embodiments, but the protection scope of the present invention is not limited thereto.

[0052] The magnetic material slicing device of the present invention includes: a machine shell, a cutting assembly, a defogging assembly, an X-axis driving assembly, a Y-axis driving assembly, a human-computer interaction device, and a controller. Further, it may also include a lifting door assembly and a fixture.

[0053] <Machine shell>

[0054] The machine shell is used to accommodate the cutting assembly, the defogging assembly, the X-axis driving assembly, the Y-axis driving assembly, the controller, and the fixture.

[0055] An operation window may be opened on the machine shell, and the user can put the magnetic material to be cut into the machine shell and take out the cut magnetic material through the operation window.

[0056] In some embodiments, the machine shell includes a first shell, a second shell, and a lifting protective cover. The first shell is located below the second shell. The second shell is in the shape of a barrel with an opening facing downwards. The second shell and the first shell are opposite to each other in the vertical direction and have a gap. The lifting protective cover can be controlled to lift and lower. When the lifting protective cover descends to contact the first shell, the gap between the first shell and the second shell is blocked by the lifting protective cover.

[0057] With such a design, the gap between the first shell and the second shell can be set large enough to facilitate the user to place and take out the magnetic material, and a relatively large number of magnetic materials can be placed.

[0058] The lifting operation of the lifting protective cover can be manual or electrically controlled. For example, the lifting protective cover is driven to lift and lower by the lifting door assembly. The lifting door assembly includes, for example, a lifting door motor, a lifting door coupling, and a lifting door transmission lead screw connected in sequence. The lifting door transmission lead screw is in transmission connection with the lifting protective cover.

[0059] In one embodiment, the lifting door motor drives the lifting door coupling to rotate through belt transmission. The rotation of the lifting door coupling drives the lifting door transmission lead screw to rotate.

[0060] <Cutting assembly>

[0061] The cutting assembly is located inside the machine shell and includes a cutter motor and a cutter. The cutter is horizontally placed and fixed in position. The cutter motor is used to drive the cutter to rotate around its axis.

[0062] In some embodiments, the blade is a circular blade. During cutting, the magnetic material moves from the outside of the blade towards the inside along the radial direction.

[0063] In some other embodiments, the blade is an annular blade. During cutting, the magnetic material moves radially outward from the inner side of the blade.

[0064] In a specific embodiment, the cutting assembly further includes a cutter transmission shaft and a tool holder. The first end of the cutter transmission shaft is connected to the output shaft of the cutter motor, and the cutter transmission shaft rotates around its own axis. The second end of the cutter transmission shaft is connected to the tool holder to drive the tool holder to rotate. The annular blade is fixed above the tool holder.

[0065] Specifically, the cutter motor and the cutter transmission shaft are connected by a belt drive. The blade is fixed to the tool holder by bolts.

[0066] <Defogging assembly>

[0067] The defogging assembly includes a defogging motor and a smoking structure. The defogging motor drives the smoking structure to exhaust the air inside the machine housing to the outside of the machine housing. The defogging assembly can be designed with reference to existing range hoods.

[0068] In the magnetic material slicing equipment, cooling oil is supplied to the fixture in real time through a pipeline. The cooling oil flows to the magnetic material, thereby cooling the cutter during cutting. When the cutter collides with the magnetic material, cooling oil mist will be generated. The defogging assembly operates during the cutting operation to exhaust the oil mist to the outside of the machine housing, preventing the inside of the magnetic material slicing equipment from being contaminated by the oil mist. After cutting is completed, the supply of the cooling oil is stopped.

[0069] The end of the pipeline for supplying the cooling oil is fixed to the sliding seat, for example.

[0070] <X-axis drive assembly>

[0071] The X-axis drive assembly is located inside the machine housing and is used to drive the magnetic material to move linearly in the horizontal direction.

[0072] In some embodiments, the X-axis drive assembly includes an X-axis servo motor, an X-axis speed reducer, an X-axis transmission lead screw, and a sliding seat connected in sequence. The X-axis transmission lead screw extends in the horizontal direction, and the sliding seat is sleeved on the X-axis transmission lead screw. The fixture is detachably fixed below the sliding seat so that the sliding seat drives the fixture to move linearly in the horizontal direction.

[0073] In one embodiment, the X-axis drive assembly includes: an X-axis servo motor, an X-axis reduction gear, a coupling, a driven shaft, a large bevel gear, a small bevel gear, an X-axis transmission lead screw, and a slide. The output end of the X-axis servo motor is connected to the X-axis reduction gear. The output end of the X-axis reduction gear is connected to the driven shaft through the coupling to drive the driven shaft to rotate. The driven shaft is connected to the large bevel gear to drive the large bevel gear to rotate, and the rotation axis of the large bevel gear extends in the vertical direction. The large bevel gear drives the small bevel gear to rotate, and the rotation axis of the small bevel gear extends in the horizontal direction. The small bevel gear drives the X-axis transmission lead screw to rotate around its own axis. The slide is sleeved on the X-axis transmission lead screw, and the rotation of the X-axis transmission lead screw drives the slide to move back and forth along the extension direction of the X-axis transmission lead screw. The X-axis transmission lead screw is horizontally arranged, so that the slide moves back and forth along the horizontal direction along the extension direction of the X-axis transmission lead screw.

[0074] <Y-axis transmission lead screw>

[0075] The Y-axis drive assembly includes a Y-axis servo motor, a Y-axis reduction gear, and a Y-axis transmission lead screw that are connected in sequence. The Y-axis transmission lead screw extends in the vertical direction, and the X-axis drive assembly is in transmission connection with the Y-axis transmission lead screw so that the entire X-axis drive assembly moves up and down.

[0076] Specifically, the output shaft of the Y-axis servo motor is connected to the Y-axis reduction gear. The Y-axis reduction gear drives the lead screw to rotate through a coupling rotating shaft and a transmission gear, so that the slide on the lead screw moves up and down.

[0077] Specifically, a slide is sleeved on the Y-axis transmission lead screw, and the rotation movement of the Y-axis transmission lead screw is converted into the up and down movement operation of the slide. The X-axis servo motor is fixedly connected to the slide on the Y-axis transmission lead screw. In this way, the entire X-axis drive assembly moves up and down.

[0078] <Human-machine interaction device>

[0079] The human-machine interaction device is, for example, a touch screen, or can also be a combination of a display screen and buttons.

[0080] The user inputs the magnetic material attribute number on the human-machine interaction device and then selects the automatic cutting mode, and the automatic cutting can be performed according to the material attributes and size attributes corresponding to the magnetic material attribute number. The process of automatic cutting is preset.

[0081] When the user selects the manual mode on the human-machine interaction device, the cutting process is operated by the user. The manual mode can be used to verify the parameters required for the automatic mode.

[0082] <Controller>

[0083] The controller can be selected from any known type of controller, such as a central processing unit CPU, a programmable logic controller PLC, a microcontroller unit MCU, etc.

[0084] In some embodiments, the human-machine interaction device is a touch screen, the controller is a programmable logic controller, the touch screen is communicatively connected to the controller through a switch, the programmable logic controller is communicatively connected to the X-axis servo driver of the X-axis servo motor, and the Y-axis servo driver of the Y-axis servo motor is communicatively connected to the Y-axis servo driver.

[0085] The servo driver is the key to controlling the movement of the servo motor. It can convert the control signal (usually an analog signal or a digital signal) into an electrical signal for driving the servo motor, and precisely control the servo motor. The servo motor is the key to performing the movement task. It can dynamically adjust the position, speed, and force according to the received signal to meet the given control requirements. The servo driver generally adopts a closed-loop control system to control the movement of the servo motor through a feedback mechanism. Specifically, the servo driver monitors the position, speed, and force of the servo motor, then compares the actual movement state with the desired movement state, calculates the error in controlling the motor movement, and feeds back the error signal to the controller for correction. In this way, precise position, speed, and force control can be achieved.

[0086] The controller is used to perform an automatic cutting operation when the cutting mode is the automatic cutting mode. The automatic cutting operation includes:

[0087] S1. Start the cutting component and the defogging component;

[0088] S2. Control the Y-axis driving component to move the magnetic material from the vertical origin position to the set height at the first speed, so that the magnetic material is opposite to the cutting tool in the horizontal direction (the height of the magnetic material matches the height of the cutting tool);

[0089] S3. Control the X-axis driving component to move the magnetic material from the horizontal origin position to approach the cutting tool at the second speed first and then continue to move to contact the cutting tool at the third speed;

[0090] S4. Control the X-axis driving component to insert the cutting tool into the magnetic material at the fourth speed to cut the magnetic material;

[0091] S5. Control the X-axis driving component to withdraw the magnetic material from the cutting tool at the fifth speed;

[0092] S6. Turn off the cutting component;

[0093] S7. Control the X-axis driving component to move the magnetic material away from the cutting tool at the sixth speed and return to the horizontal origin position;

[0094] S8. Control the Y-axis driving component to return the magnetic material to the vertical origin position at the seventh speed;

[0095] Wherein, the first speed ≥ the second speed > the third speed ≥ the fourth speed;

[0096] Wherein, the sixth speed > the fifth speed > the fourth speed;

[0097] Wherein, the seventh speed > the fifth speed;

[0098] Wherein, the cutting scheme includes: the first speed, the second speed, the third speed, the fourth speed, the fifth speed, the sixth speed, and the seventh speed, and the cutting scheme corresponds one-to-one with the magnetic material attribute number.

[0099] In this way, a primary cutting of the magnetic material is completed.

[0100] In some embodiments, the automatic cutting operation further includes: performing one or more rounds of a set of operations in a loop between step S5 and step S6, and the set of operations includes:

[0101] S50. Controlling the X driving component to move the magnetic material away from the cutting tool at the third speed (the moving position end point is on the same vertical line as the action starting point of moving to contact the cutting tool at the third speed in step S3);

[0102] S51. Controlling the Y-axis driving component to move the magnetic material from the current position to another set height at the first speed, so that the magnetic material is opposite to the cutting tool in the horizontal direction;

[0103] S52. Controlling the X-axis driving component to move the magnetic material from the current position to contact the cutting tool at the third speed;

[0104] S53. Controlling the X-axis driving component to make the cutting tool penetrate into the magnetic material at the fourth speed to cut the magnetic material;

[0105] S54. Controlling the X-axis driving component to move the magnetic material out of the cutting tool at the fifth speed.

[0106] In this way, multiple cuttings of the magnetic material are completed, that is, one piece of magnetic material is cut into three or more pieces.

[0107] Note that the position of the above cutting tool is fixed, and the magnetic material moves in a straight line in the horizontal direction and a straight line in the vertical direction.

[0108] In some embodiments, the controller is further configured to perform a manual cutting operation in the manual mode, and the manual cutting operation includes: in response to an operation of the user on the human-computer interaction device, controlling the start and stop of the cutting component, controlling the start and stop of the defogging component, controlling the speed and displacement of the magnetic material moving in the horizontal direction, and controlling the speed and displacement of the magnetic material moving in the vertical direction.

[0109] In other words, each operation step in the cutting process in the automatic mode is controlled by the user on the human-machine interaction module.

[0110] <Lifting door assembly>

[0111] The lifting door assembly is used to drive the lifting protective cover to lift and lower. The automatic cutting operation further includes:

[0112] Before step S1, an instruction is sent to the lifting door assembly to cause the lifting door assembly to drive the lifting door protective cover to descend until it contacts the first housing.

[0113] After step S8, an instruction is sent to the lifting door assembly to cause the lifting door assembly to drive the lifting door protective cover to rise.

[0114] Prevent the user from touching the cutting tool and ensure the safe operation of the cutting process.

[0115] <Fixture>

[0116] The fixture is in the shape of an openable and closable cylindrical housing. A plurality of openings are provided on its side wall. The plurality of openings are arranged at intervals along the axial direction of the fixture, and the plurality of openings extend along the circumferential direction of the fixture. The plurality of openings are used for the cutting tool to be inserted therein, so as to cut the magnetic material placed in the fixture.

[0117] In one embodiment, there are various ways to open and close the fixture. For example, the upper end surface of the cylindrical housing is fixed and separable through a snap structure, so as to open the upper end surface and place the magnetic material into the fixture.

[0118] In another embodiment, the fixture is composed of two symmetric parts on the left and right. The two parts are hinged, so that the two parts can be rotated to the open state and the closed state, which is convenient for taking and placing the magnetic material into and out of the fixture.

The output end of the X-axis servo motor 41 is connected to the X-axis speed reducer 42. The output end of the X-axis speed reducer 42 is connected to the driven shaft 44 through the coupling 43 to drive the driven shaft 44 to rotate. The driven shaft 44 is connected to the large bevel gear 45 to drive the large bevel gear 45 to rotate, and the rotation axis of the large bevel gear 45 extends in the vertical direction. The large bevel gear 45 drives the small bevel gear 46 to rotate, and the rotation axis of the small bevel gear 46 extends in the horizontal direction. The small bevel gear 46 drives the X-axis transmission lead screw 47 to rotate around its own axis. The carriage 48 is sleeved on the X-axis transmission lead screw 47, and the rotation of the X-axis transmission lead screw 47 drives the carriage 48 to move back and forth along the extension direction of the X-axis transmission lead screw 47. The X-axis transmission lead screw 47 is horizontally arranged, so that the carriage 48 moves back and forth along the extension direction of the X-axis transmission lead screw 47 in the horizontal direction.

[0134] The X-axis servo motor 41 is fixedly connected to the housing of the X-axis drive assembly.

[0135] Referring to Figure 3 and Figure 4 The number of X-axis transmission lead screws 47 is 8. In the front view projection of the plane where the magnetic material slicing equipment is located, the front projections of the X-axis transmission lead screws 47 are equally angularly distributed with the front projection of the X-axis speed reducer 42 as the center, and the front projection of the cutter 54 is in the shape of a ring, and the front projection of the fixture 6 can move from the inside of the front projection of the cutter 54 to overlap with the front projection of the cutter 54.

[0136] In the cutting state, the carriage 48 is located above the cutter 54. At this time, the fixture 6 and the cutter 54 are arranged opposite to each other in the horizontal direction. When the fixture 6 moves horizontally towards the cutter 54, the cutter 54 cuts the magnetic material clamped by the fixture 6.

[0137] The human-machine interaction device is located outside the machine shell and is used to receive the magnetic material attribute number and the cutting mode. The magnetic material attribute number is associated with the magnetic material size and material type.

[0138] The controller is used to perform an automatic cutting operation when the cutting mode is the automatic cutting mode. The automatic cutting operation includes the following operations.

[0139] S1. Start the cutting component and the defogging component.

[0140] S2. Control the Y-axis drive component to move the magnetic material from the vertical origin position to the set height at the first speed, so that the magnetic material is opposite to the cutter 54 in the horizontal direction.

[0141] S3. Control the X-axis drive component to move the magnetic material from the horizontal origin position to approach the cutter 54 at the second speed first and then continue to move to contact the cutter 54 at the third speed.

[0142] S4. Control the X-axis drive component to make the cutter 54 penetrate into the magnetic material at the fourth speed to cut the magnetic material.

[0143] S5. Control the X-axis drive component to withdraw the magnetic material from the cutter 54 at the fifth speed.

[0144] Execute a set of operations in a loop for 2 rounds. A set of operations includes:

[0145] S50. Control the X-axis drive component to move the magnetic material away from the cutter at the third speed, and the line connecting the action end point and the position start point of the movement at the third speed in step S3 extends vertically.

[0146] S51. Control the Y-axis drive component to move the magnetic material from the current position to another set height at the first speed, so that the magnetic material is opposite to the cutter 54 in the horizontal direction.

[0147] S52. Control the X-axis drive component to move the magnetic material from the current position to contact the cutter 54 at the third speed.

[0148] S53. Control the X-axis drive component to make the cutter 54 penetrate into the magnetic material at the fourth speed to cut the magnetic material.

[0149] S54. Control the X-axis drive component to withdraw the magnetic material from the cutter 54 at the fifth speed.

[0150] S6. Turn off the cutting component.

[0151] S7. Control the X-axis drive component to move the magnetic material away from the cutter 54 at the sixth speed and return to the horizontal origin position.

[0152] S8. Control the Y-axis drive component to return the magnetic material to the vertical origin position at the sixth speed.

[0153] Among them, the first speed > the second speed > the third speed;

[0154] Among them, the sixth speed > the fifth speed > the fourth speed;

[0155] Among them, the cutting plan includes: the first speed, the second speed, the third speed, the fourth speed, the fifth speed, the sixth speed and the seventh speed, and the cutting plan corresponds to the magnetic material attribute number one by one.

[0156] The further cutting scheme also includes the starting and ending points of the moving positions in each moving step of the magnetic material.

[0157] Cutting example 1:

[0158] The magnetic material is a cylinder with a diameter of 10 mm and a height of 10 mm.

[0159] The first speed is 500 mm / min (the speed of moving rapidly downward in the vertical direction), the second speed is 400 mm / min (the speed of moving rapidly close to the cutter 54 in the horizontal direction), the third speed is 5 mm / min (the speed of moving slowly horizontally until contacting the cutter 54), the fourth speed is 2.5 mm / min (the speed of the magnetic material moving horizontally towards the cutter 54 for cutting), the fifth speed is 3 mm / min (the speed of the magnetic material moving horizontally out of the cutter 54), the sixth speed is 300 mm / min (the speed of the magnetic material moving horizontally back to the original horizontal position), and the seventh speed is 300 mm / min (the speed of the magnetic material moving vertically back to the original vertical position).

[0160] Cutting example 2:

[0161] The magnetic material is a cylinder with a diameter of 50 mm and a height of 20 mm.

[0162] The first speed is 500 mm / min (the speed of moving rapidly downward in the vertical direction), the second speed is 400 mm / min (the speed of moving rapidly close to the cutter 54 in the horizontal direction), the third speed is 1.5 mm / min (the speed of moving slowly horizontally until contacting the cutter 54), the fourth speed is 1.5 mm / min (the speed of the magnetic material moving horizontally towards the cutter 54 for cutting), the fifth speed is 2.5 mm / min (the speed of the magnetic material moving horizontally out of the cutter 54), the sixth speed is 300 mm / min (the speed of the magnetic material moving horizontally back to the original horizontal position), and the seventh speed is 300 mm / min (the speed of the magnetic material moving vertically back to the original vertical position).

[0163] The magnetic material compositions of the above two cutting examples are the same, and the differences in the cutting schemes are described as follows.

[0164] Due to the increase in the size of the magnetic material, the fifth speed needs to be lowered to avoid chipping. The larger the material size, the easier it is to chip.

[0165] The first speed, second speed, sixth speed, and seventh speed during the cutting of the two magnetic materials are correspondingly equal. This is because these 4 speeds have little relation to the magnetic material to be cut and can be set to be equal.

[0166] The larger the size of the magnetic material, the larger the contact area when the cutting tool 54 first contacts the magnetic material. The third speed needs to be appropriately reduced to ensure that the surface of the magnetic material is not damaged. Similarly, the speed when the cutting tool 54 exits the magnetic material also needs to be appropriately reduced, that is, the fifth speed will also be appropriately reduced.

[0167] The larger the size of the magnetic material, the larger the contact area between the cutting tool 54 and the magnetic material during the cutting process, the higher the cutting temperature rises, and the greater the force on the magnetic material. Therefore, the fourth speed needs to be appropriately reduced.

[0168] Continue to refer to Figure 1 , the machine shell includes a first housing 71, a second housing 72, and a lifting protective cover 73. The first housing 71 is located below the second housing 72. The second housing 72 is in the shape of a barrel with an opening facing downwards. The second housing 72 and the first housing 71 are opposite to each other in the vertical direction and have a gap. The lifting protective cover 73 can be controlled to lift and lower. When the lifting protective cover 73 descends to contact the first housing 71, the gap between the first housing 71 and the second housing 72 is blocked by the lifting protective cover 73.

[0169] The magnetic material slicing device further includes a lifting door assembly for driving the lifting protective cover 73 to lift and lower. The automatic cutting operation further includes:

[0170] Before step S1, issue an instruction to the lifting door assembly to cause the lifting door assembly to drive the lifting protective cover 73 to descend until it contacts the first housing 71;

[0171] After step S8, issue an instruction to the lifting door assembly to cause the lifting door assembly to drive the lifting protective cover 73 to rise.

[0172] The lifting door assembly includes a lifting door motor 1, a lifting door coupling (not shown), and a lifting door transmission lead screw (not shown) connected in sequence. The lifting door transmission lead screw is in transmission connection with the lifting protective cover 73.

[0173] Refer to Figure 5 , the magnetic material slicing device further includes a fixture 6, which is in the shape of an openable and closable cylindrical housing. A plurality of openings 61 are provided on its side wall. The plurality of openings 61 are arranged at intervals along the axial direction of the fixture 6. The plurality of openings 61 extend along the circumferential direction of the fixture 6. The plurality of openings 61 are used for the cutting tool 54 to be inserted therein, so as to cut the magnetic material placed in the fixture 6.

[0174] The fixture 6 is hinged at its left and right parts. From Figure 5 the current perspective, the hinge position (not shown) is located at the rear side of the fixture 6. Figure 5 The seam 62 where the left and right parts of the fixture 6 are butted is shown in

[0175] The lower surface of the slider 48 is grooved (not shown), and the fixture 6 is inserted into the groove on the lower surface of the slider 48. Threaded holes (not shown) are provided on the groove walls of the groove, and the threaded holes extend in the horizontal direction. The fixture 6 is fixedly connected to the slider 48 by screwing a screw (not shown) into the threaded hole.

[0176] Reference Figure 2 , the human-computer interaction device is the touch screen 81, the controller is the programmable logic controller 83, the touch screen 81 is communicatively connected to the controller through the switch 82, the programmable logic controller 83 is communicatively connected to the X-axis servo driver 84 of the X-axis servo motor 41, and the Y-axis servo driver 85 of the Y-axis servo motor 31 is communicatively connected to the X-axis servo driver 84.

[0177] The controller is further configured to perform a manual cutting operation in the manual mode. The manual cutting operation includes: controlling the start and stop of the cutting assembly, controlling the start and stop of the defogging assembly, controlling the speed and displacement of the magnetic material moving in the horizontal direction, and controlling the speed and displacement of the magnetic material moving in the vertical direction in response to the user's operation on the human-computer interaction device.

[0178] The following describes the operation process of the automatic mode. The user inputs or selects the magnetic material attribute number and the automatic mode on the touch screen 81, fixes the fixture 6 with the magnetic material on the slider 48 on the X-axis transmission lead screw 47, and then clicks the start button on the touch screen 81. Subsequently, the lifting protective cover 73 descends. Then the cutting tool 54 starts to rotate, the defogging motor 2 starts to exhaust the flue gas, the cooling oil supply assembly starts to supply the cooling oil, and the Y-axis driving assembly and the X-axis driving assembly cooperate to move the magnetic material to contact the cutting tool 54 and continue to move outwards. After the first cut is completed, the second and third cuts are performed. Subsequently, the X-axis driving assembly and the Y-axis driving assembly drive the magnetic material to return to the original position. Then the cutting tool motor 51 is turned off, the defogging motor 2 is turned off, and the supply of the cooling oil is stopped. Then the lifting protective cover 73 rises to expose the fixture 6, and the user takes away the fixture 6. A complete cutting process ends.

[0179] Example 2

[0180] Reference Figure 6 And in combination with Figure 4 , the difference between Embodiment 2 and Embodiment 1 is only that: the shapes of the slider 48 and the fixture 6 are different, and the separable fixing methods of the slider 48 and the fixture 6 are different.

[0181] The slider 48 includes a horizontal portion and a vertical portion. The horizontal portion extends in the horizontal direction and is sleeved on the X-axis transmission lead screw 47. The bottom of the vertical portion provides a groove for the fixture 9 to be inserted.

[0183] The non-free end of the locking handle 91 is hinged to the vertical part of the clamp 48. The locking handle 91 can rotate up and down. The non-free end of the locking handle 91 is hinged to the upper part of the connecting member 94. The lower part of the connecting member 94 is hinged to the sleeve 92, and the sleeve 92 is inserted into the collar 93. The collar 93 is fixed relative to the vertical part of the slider 48, and the opening direction is the vertical direction. A column is fixed above the clamp 6, and the column extends in the up and down direction and is inserted into the sleeve 92 from the lower opening of the sleeve 92.

[0184] The user presses the locking handle 91 downward, thereby pressing the clamp 6 downward into the slot of the vertical portion of the slider 48 , thereby achieving a fixed connection between the clamp 6 and the slider 48 .

[0185] The user lifts the locking handle 91 upward, thereby releasing the slider 48 , and then the user takes the slider 48 away.

[0186] The present invention is not limited to the above-mentioned embodiments. Without departing from the essential content of the present invention, any deformation, improvement and substitution that can be conceived by those skilled in the art shall fall within the scope of the present invention.
