Description

Device for manufacturing a stator for a spiral core of an axial flux type motor and method for manufacturing the same

[0001] The present invention relates to an apparatus for manufacturing a stator for a spiral core of an axial flux type motor and a method for manufacturing the same. More specifically, it relates to an apparatus and a method for manufacturing a spiral core of a stator for an axial flux type motor through a series of processes including laminating, winding, welding, and cutting the core under a certain tension.

[0002] Generally, the stator of a motor utilizes a laminated core manufactured by stacking multiple lamina members, which are formed by forming a magnetic material, such as a thin steel plate, using a press forming device. The multiple lamina members are manufactured by punching steel plates using a press forming device and are firmly bonded to adjacent lamina members through a process of applying adhesive or welding with a welding machine while maintaining right angles and concentricity. However, the method of stacking and joining multiple laminas as described above had the disadvantage of being difficult to precisely maintain right angles and concentricity. Therefore, to solve the above problem, Patent Document 1 discloses a winding unit for manufacturing a spring-type stator core that can quickly and easily manufacture a spring-type stator core by including a winding unit that rotates a base material punched from a blanking unit using an indexing servo motor to wind it into a spring-like shape, a pressure unit that guides the base material to be wound neatly, and a control unit that controls the blanking unit and the winding unit to work together.

[0003] The above prior art has the problem that, when manufacturing a single stator core, the base material must be withdrawn from the winding section and manually fixed, and as the diameter of the base material wound in the winding section increases, the tension acting on the base material to be wound changes, making it impossible to align the teeth consistently and thus making it impossible to manufacture a stator core of a uniform shape.

[0004] The present invention aims to solve the above problem and to provide a stator for a spiral core having a constant right angle and concentricity by forming a strip-shaped steel plate into a certain shape while conveying it, laminating and winding it, and undergoing a welding process.

[0005] In addition, another objective of the present invention is to automatically and repeatedly manufacture a stator for a spiral core by first manually withdrawing a strip steel plate and loading it onto a conveying means, and then winding a laminated core with uniform tension.

[0006] To achieve the above objective, the present invention comprises: a conveying means for conveying a strip-shaped steel plate supplied from a steel plate roll; a pressing forming means for forming a punched portion by press-cutting one side of the steel plate conveyed by the conveying means into a certain shape at a certain interval; a steel plate finger means for gripping and fixing the steel plate conveyed by the conveying means; a steel plate cutting means for cutting the steel plate while the steel plate finger means is gripping the steel plate; a lamination means for stacking the steel plate to a certain thickness while rotating in one direction with a transmitted rotational force while fixing the end of the steel plate conveyed by the conveying means with a jaw; a jaw clamping means for fixing and connecting the jaw of the lamination means to rotate together with the lamination means; and a welding means for fixing one side of the steel plate stacked by winding it a certain number of times initially in the lamination means by primary welding, and for secondary welding one side of the steel plate after lamination is completed in the lamination means. The present invention is characterized by providing a stator manufacturing device for a spiral core of an axial flux type motor, comprising: an up-and-down position control means for controlling the up-and-down position of the laminating means so that the strip steel plate, which is laminated and wound in the laminating means, is horizontal with the position supplied by the conveying means; a left-right position control means for controlling the left-right position of the laminating means to maintain the gap between the laminating means and the conveying means and to cut and remove the strip steel plate; and an extraction means for extracting the laminating core, which has been laminated in the laminating means, from the laminating means.

[0007] In addition, the present invention may further include an extraction robot that grasps and discharges a laminated core extracted from the extraction means using a holder configured at the end of an arm.

[0008] In addition, in the present invention, the welding means welds the strip steel plate after winding it 2 to 4 times in the lamination means during the first welding, and the lamination core may include a fan-shaped winding section and a rectangular blanking section.

[0009] In addition, the present invention comprises: (a) a step of initially withdrawing a strip steel plate from a strip steel plate roll wound with a strip-shaped thin film strip steel plate before processing, and manually inserting it into the jaw of a lamination means via a transfer means; (b) a step in which, when the end of the strip steel plate is inserted into the jaw of the lamination means, the jaw clamping means is moved to the left to align with the jaw of the lamination means in a fixed position, and then the third air cylinder of the jaw clamping means is advanced to clamp the jaw; (c) a step in which, after the jaw clamping means clamps the jaw, the second servo motor is operated to bend the strip steel plate to a certain angle and then stop, the third servo motor is operated to lower the lamination means to a certain height, the fourth servo motor is operated to move it to the left, and then preparation for rolling the strip steel plate; (d) a step in which the second servo motor is operated to start rolling the strip steel plate; (e) a step of rotating the second servo motor a certain number of times to roll the steel strip and then stopping it, and fixing the steel strip rolled a certain number of times by first welding one side of the rolled steel strip on the lamination means using a welding machine; (f) a step of operating the second servo motor to roll the steel strip onto the lamination means to a certain thickness, while operating the fourth servo motor to move the lamination means backward to the right according to the position of the punching part formed on the steel strip, and operating the third servo motor to lower it downward according to the lamination height of the steel strip; (g) a step of winding the steel strip on the lamination means along with rolling the steel strip; (h) a step of fixing one side of the lamination core where the winding of the steel strip is completed by second welding using a welding means; (i) a step of moving the steel strip finger means and the steel strip cutting means to the right by operating the first servo motor when the second welding is completed; (j) a step of operating the first air cylinder of the strip steel plate finger means to advance it, then gripping and fixing the strip steel plate with the finger, and operating the second air cylinder of the strip steel plate cutting means to advance it; (k) a step of the cutter of the strip steel plate cutting means cutting the strip steel plate while the finger of the strip steel plate finger means is gripping the strip steel plate;(l) a step of retracting the cutter of the strip steel plate cutting means by operating the second air cylinder after cutting the strip steel plate; (m) a step of releasing the clamping by retracting the jaw clamping means that clamps the jaw of the lamination means; (n) a step of retracting the jaw clamping means to the right; (o) a step of discharging the laminated core fixed to the lamination means by operating the fifth air cylinder of the extraction means; (p) a step of ejecting the laminated core discharged by the extraction means by grasping it with a holder configured at the end of the arm of the extraction robot. The present invention provides a method for manufacturing a stator for a spiral core of an axial flux type motor.

[0010] In addition, the present invention may further include the step of (q) the finger of the strip steel plate finger means gripping the end of the strip steel plate moving to the right by the operation of the first servo motor and inserting the end of the strip steel plate into the jaw of the stacking means.

[0011] According to an embodiment of the present invention, a laminated core can be manufactured in one step through a series of processes of laminating, winding, welding, and cutting a spiral core of an axial flux type motor with a constant tension, thereby lowering the production cost of the axial flux type motor and increasing the production volume. Additionally, by automatically supplying the strip steel plate for manufacturing the laminated core to the laminating means via a conveying means, except for the initial one time, the manufacturing process is automated, and the inconvenience of manually transporting and fixing the steel plate to the laminating means every time a laminated core is manufactured can be avoided. Furthermore, by rolling the laminating means up and down and left and right according to the diameter of the strip steel plate, the steel plate maintains a state parallel to the bottom surface and is wound under a constant tension, thereby having the advantage of manufacturing a stator of a uniform shape.

[0019] Hereinafter, an embodiment of a stator manufacturing device for a spiral core of an axial flux type motor according to the present invention will be described with reference to the attached drawings.

[0020] Furthermore, FIG. 1 is a block diagram schematically illustrating a stator manufacturing device for a spiral core of an axial flux type motor according to the present invention, and FIG. 3 to 11 are described with reference to an operation diagram including a plan view and a side view of a stator manufacturing device for a spiral core of an axial flux type motor according to the present invention.

[0021] The conveying means (100) conveys a strip-shaped steel plate (11) supplied from a strip steel plate roll (10), and the conveying means (100) causes the strip steel plate (11) supplied from the strip steel plate roll (10) to be supplied horizontally with a certain tension through a plurality of rolls.

[0022] The pressing forming means (200) forms a punching section (12) by press-cutting one side of a strip steel plate (11) conveyed by the conveying means (100) into a certain shape at a certain interval. The pressing forming means (200) varies the pitch interval of punching the strip steel plate (11) while rotating with pneumatic pressure. This is the strip steel plate (11) punched by the pressing forming means (200) for winding the laminated core (20) for the stator core in FIG. 12a. The laminated core (20) has a structure that is wound and laminated, and when making the punching section (12) with the pressing forming means (200), the inner length interval gradually increases as it goes toward the outer length interval, so the position value of the servo motor is corrected to correct the interval. And as shown in FIG. 12b, the fan-shaped winding section (21) of the strip steel plate (11) becomes wider from the inside to the outside, while the rectangular blanking section (22) is formed with the same width. FIG. 12c is a side cross-section showing the winding section (21) and the blanking section (22). FIG. 12d shows the back side where the blanking section (22) is not formed, and the laminated core (20) for the stator core is wound from the inner diameter to the outer diameter with a constant thickness.

[0023] Furthermore, as shown in the graph illustrating the calculated pitch value of the servo motor in FIG. 13, it can be seen that the outer diameter and the outer diameter increase with the rotational speed, and the sum of the diameters also increase. The calculated pitch value of the servo motor may vary depending on the size or rotational speed for the optimization of the stacked core (20) for the stator core.

[0024] The finger means (300) is for gripping and cutting the strip steel plate (11), and grips and fixes the strip steel plate (11) transported from the transport means (100). The strip steel plate finger means (300) is installed on one side of the front of the transport means (100). The strip steel plate finger means (300) is configured to move left and right along a guide rail (321) fixedly installed on a workbench (2) by driving a first servo motor (320). The strip steel plate finger means (300) is operated forward and backward by a first air cylinder (302) and includes a pair of upper and lower fingers (301) configured at the shaft end of the first air cylinder (302). The fingers (301) grip the upper and lower surfaces of the supplied strip steel plate (11) and fix the strip steel plate (11). Furthermore, the strip steel plate finger means (300) includes the function of inserting the strip steel plate (11) into the jaw (401) of the lamination means (400).

[0025] The strip steel plate cutting means (310) cuts the strip steel plate (11) while the strip steel plate finger means (300) is gripping the strip steel plate (11). The strip steel plate cutting means (310) is installed on one side of the strip steel plate finger means (300) and is configured to move left and right along a guide rail (321) fixedly installed on a workbench (2) by driving a first servo motor (320). The strip steel plate cutting means (310) is operated forward and backward by a second air cylinder (312) and includes a cutter (311), such as scissors, configured at the shaft end of the second air cylinder (312). The cutter (311) grips the upper and lower surfaces of the supplied strip steel plate (11) and cuts the strip steel plate (11).

[0026] The lamination means (400) laminates the strip steel plate (11) to a certain thickness by rotating it in one direction with the rotational force transmitted while fixing the end of the strip steel plate (11) conveyed from the conveying means (100) with a jaw (401). The lamination means (400) rotates in one direction by being axially connected through a pulley by the operation of the second servo motor (410). The lamination means (400) includes a jaw capable of fixing the end of the supplied strip steel plate (11).

[0027] The jaw clamping means (500) rotates together with the stacking means (400) by fixing the jaw (401) of the stacking means (400). The jaw clamping means (500) is transported left and right on a guide rail and moves forward and backward by the operation of the third air cylinder (510). The jaw clamping means (500) includes a clamp (501) that presses and fixes the jaw (401) of the stacking means (400).

[0028] The welding means (600) first welds and fixes one side of the strip steel plate (11) that has been wound and stacked by an initial fixed number of times in the stacking means (400), and secondly welds one side of the strip steel plate (11) that has been stacked by the stacking means (400). The welding means (600) moves forward and backward by the operation of the fourth air cylinder (610) to weld and fix the side of the wound stacked core (20). Furthermore, during the first welding, the welding means (600) welds the strip steel plate (11) after winding it about 2 to 4 times by the stacking means (400), thereby fixing the strip steel plate (11) wound in a circular shape so that it does not unravel.

[0029] The vertical position control means (700) controls the vertical position of the stacking means (400) so that the strip steel plate (11), which is stacked and wound in the stacking means (400), becomes horizontal to the position supplied from the conveying means (100). The vertical position control means (700) raises and lowers the bracket (3) installed on the lifting member (701) by operating the third servo motor (710) to adjust the vertical position of the stacking means (400). The vertical position control means (700) adjusts the strip steel plate (11) supplied through the conveying means (100) to become horizontal while the strip steel plate (11) is wound in the stacking means (400).

[0030] Furthermore, the left-right position control means (800) controls the left-right position of the stacking means (400) to maintain the gap between the stacking means (400) and the transfer means (100) and to cut and extract the strip steel plate (11). The left-right position control means (800) moves the transfer member (801) installed on the guide rail (802) left and right by the operation of the fourth servo motor (810). An up-down position control means (700) is installed on the transfer member (801), and the stacking means (400) is moved left and right through the up-down position control means (700).

[0031] The extraction means (900) extracts the laminated core (20), which has been completed in the lamination means (400), from the lamination means (400). The extraction means (900) is installed at the rear of the lamination means (400) and separates the laminated core (20), which has been completed in the jaw (401) by operating the fifth air cylinder (902), by pushing it with the ejector (901).

[0032] The extraction robot (910) holds the laminated core (20) extracted from the extraction means (900) with a holder (912) configured at the end of the arm (911) and discharges the manufactured laminated core (20) for the stator core. The extraction robot (910) is installed on one side of the stator manufacturing device for the spiral core of the axial flux type motor of the present invention. The extraction robot (910) is configured with a multi-axis arm (911) and has three-dimensional movements such as rotation, left and right, lifting and lowering, and direction change.

[0033] A method for manufacturing a stator for a spiral core of an axial flux type motor according to the present invention, configured as described above, will be explained with reference to the operation diagrams of FIGS. 3 to 11 and the flowchart of FIG. 14.

[0034] First, the strip steel plate (11) is initially drawn out from the strip steel plate roll (10) on which the strip steel plate (11) in the shape of a thin film before processing is wound, and then manually inserted into the jaw (401) of the stacking means (400) via the conveying means (100) (S1). That is, in order to manufacture a stator for a spiral core of an axial flux type motor using the manufacturing device (1) of the present invention, the strip steel plate (11) is initially drawn out by a worker manually from the strip steel plate roll (10) once, and then inserted into the jaw (401) of the stacking means (400) via a plurality of rolls configured in the conveying means (100) to be fixed. Afterwards, the strip steel plate (11) can be automatically inserted into the jaw (401) of the lamination means (400) using the strip steel plate finger means (300) without the worker manually inserting the strip steel plate (11) into the jaw (401).

[0035] When the end of the strip steel plate (11) is inserted into the jaw (401) of the stacking means (400), the jaw clamping means (500) is moved to the left to align with the jaw (401) of the stacking means (400) in the correct position, and then the third air cylinder (510) of the jaw clamping means (500) is advanced to clamp the jaw (401) (S2). At this time, the jaw clamping means (500) moves to the left from a state where it has retracted to the right, and then the clamp (501) advances by the operation of the third air cylinder (510) to press and fix the jaw (401) into which the strip steel plate (11) is inserted.

[0036] After the jaw clamping means (500) clamps the jaw (401), the second servo motor (410) is operated to bend the strip steel plate (11) at a certain angle and then stop, the third servo motor (710) is operated to lower the stacking means (400) to a certain height, and the fourth servo motor (810) is operated to move it to the left and then prepare for rolling the strip steel plate (11) (S3). That is, the stacking means (400) rotates by the operation of the second servo motor (410) so that the end of the strip steel plate (11) is bent at approximately 90 degrees, and in this state, the operation of the third servo motor (710) lowers the strip steel plate (11) supplied from the conveying means (100) to level it, and the operation of the fourth servo motor (810) causes the stacking means (400) to advance to the left.

[0037] Next, the second servo motor (410) is operated to start rolling the strip steel plate (11) (S4). Then, the second servo motor (410) is rotated a certain number of times, for example, approximately 2 to 4 times, to roll the strip steel plate (11) so that it is wound, and then stopped. Then, one side of the strip steel plate (11) rolled on the lamination means (400) is welded first using the welding means (600) to fix the strip steel plate (11) that has been rolled a certain number of times (S5). The welding means (600) is operated by the fourth air cylinder (610) to contact the side of the strip steel plate (11) that has been wound a certain number of times so that welding is performed.

[0038] Afterwards, the second servo motor (410) is operated to roll the strip steel plate (11) onto the lamination means (400) to a certain thickness, while the fourth servo motor (810) is operated to move the lamination means (400) backward to the right according to the position of the punching portion (12) formed on the strip steel plate (11), and the third servo motor (710) is operated to lower the strip steel plate (11) according to the lamination height (S6). Then, the strip steel plate (11) is wound along with rolling of the strip steel plate (11) onto the lamination means (400), that is, rolling in the up-down and left-right directions of the third servo motor (710) and the fourth servo motor (810) (S7).

[0039] Then, one side of the laminated core (20) on which the winding of the strip steel plate (11) is completed is fixed by secondary welding using a welding means (600) (S8). The welding means (600) contacts the side of the strip steel plate (11) wound a certain number of times by the operation of the fourth air cylinder (610) so that welding is performed.

[0040] When the second welding is completed, the first servo motor (320) is operated to move the strip steel plate finger means (300) and the strip steel plate cutting means (310) to the right (S9). This is to cut the strip steel plate (11) supplied from the transfer means (100) to the stacking means (400). Then, the first air cylinder (302) of the strip steel plate finger means (300) is operated to advance it, the strip steel plate (11) is gripped and fixed with the finger (301), and the second air cylinder (312) of the strip steel plate cutting means (310) is operated to advance it (S10). Afterward, while the finger (301) of the strip steel plate finger means (300) is gripping the strip steel plate (11), the cutter (311) of the strip steel plate cutting means (310) cuts the strip steel plate (11) (S11). After the cutter (311) of the strip steel plate cutting means (310) cuts the strip steel plate (11), the second air cylinder (312) is operated to retract the strip steel plate cutting means (310) (S12). At this time, the strip steel plate finger means (300) remains in a state of continuously gripping one end of the cut strip steel plate (11).

[0041] Next, the jaw clamping means (500) that clamps the jaw (401) of the stacking means (400) is retracted to release the clamping state (S13). Then, the jaw clamping means (500) is retracted to the right (S14).

[0042] Afterwards, the stacked core (20) fixed to the stacking means (400) is discharged by operating the fifth air cylinder (902) of the extraction means (900) (S15). Then, the stacked core (20) discharged by the extraction means (900) is ejected by grasping the holder (912) configured at the end of the arm (911) of the extraction robot (910) (S16).

[0043] Additionally, after ejecting the stacking core (20), the third servo motor (710) and the fourth servo motor (810) are each operated to move the stacking means (400) to the left, and the finger (301) of the strip steel plate finger means (300) holding the end of the strip steel plate (11) moves to the right by the operation of the first servo motor (320) to insert the end of the strip steel plate (11) into the jaw (401) of the stacking means (400) (S17). Then, the steps after the above step (S2) are repeatedly and automatically performed.

[0044] Therefore, as shown in the photographs of FIGS. 15a to 15e, the laminated core for a stator core manufactured by the manufacturing method of the present invention can be seen to be divided into a fan-shaped winding section (21) and a rectangular-shaped blanking section (22).

[0045] As described above, the stator manufacturing apparatus for a spiral core of an axial flux type motor and the manufacturing method thereof according to the present invention have the advantage of improving productivity by automating a series of processes for manufacturing a laminated core for a stator core.

[0046] The embodiments described above in the present invention are merely examples, and the present invention is not limited thereto. Any configuration substantially identical to the technical concept described in the claims of the present invention and achieving the same functional effect is included within the technical scope of the present invention.
