Description

Technical Field

[0001] This invention relates to the field of silicon steel sheet processing technology, and particularly to silicon steel sheet processing equipment. Background Technology

[0002] As a core component of power equipment such as transformers and motors, the quality of the iron core directly determines the energy efficiency, noise level, and service life of the equipment. The lamination precision and consistency of the iron core are key factors affecting its performance. Currently, iron core production largely relies on manual operation or semi-automated equipment, which presents several technical shortcomings. First, the production preparation stage is inefficient. In traditional production, every time a new specification of iron core product is changed, the operator needs to reprogram and set complex process parameters such as cutting length, angle, and lamination layers. This not only requires operators to have high professional skills, but also takes a long time to debug the parameters, resulting in a significant waste of time and manpower. It is also easy for human error to cause parameter deviations, which in turn affects product quality.

[0003] Secondly, the shearing and feeding processes have a low degree of automation. During production, the shearing mechanism can only cut strips of fixed length, and the feeding mechanism can only transport strips of fixed width. Whenever the width parameters or shearing length parameters of the silicon steel sheet change, the machine needs to be stopped for adjustment, which reduces production efficiency.

[0004] Therefore, there is an urgent need for a core production technology with a high degree of automation, precise parameter control, and a continuous production process to address the many shortcomings of existing technologies. Summary of the Invention

[0005] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a silicon steel sheet processing equipment capable of adapting to the production of various dimensional parameters and improving production efficiency.

[0006] A silicon steel sheet processing apparatus according to a first aspect of the present invention includes: Unwinding mechanism, used to hold silicon steel sheet coils; A shearing mechanism is disposed behind the unwinding mechanism and is used to shear the silicon steel sheet coil. The shearing mechanism includes a base plate, a first shearing unit and a second shearing unit. The first shearing unit and the second shearing unit are arranged at intervals along the conveying direction of the silicon steel sheet and are fixedly disposed on the base plate. The arrangement directions of the first shearing unit and the second shearing unit intersect to form an included angle. A first driving device is used to drive the shearing mechanism to move. The feeding mechanism includes a first limiting module and a second limiting module, which are arranged opposite to each other. Both the first limiting module and the second limiting module are provided with limiting plates, and the limiting plates are provided with limiting grooves. The side of the silicon steel sheet is located in the limiting groove. The control system has a built-in iron core pattern library, which stores a variety of silicon steel sheet patterns. The control system can be used to select one of the silicon steel sheet patterns and to adjust the width and cutting length parameters of the silicon steel sheet pattern. The feeding mechanism further includes a synchronization mechanism. The control system adjusts the first limiting module and the second limiting module through the synchronization mechanism according to the silicon steel sheet width parameter, so that the first limiting module and the second limiting module synchronously move towards the theoretical center line of the silicon steel sheet or synchronously unfold in a direction away from the theoretical center line. The control system controls the unwinding speed of the unwinding mechanism according to the silicon steel sheet shearing length parameter, and controls the first driving device to drive the shearing mechanism to move in a direction perpendicular to the conveying direction of the silicon steel sheet.

[0007] The silicon steel sheet processing equipment according to embodiments of the present invention has at least the following beneficial effects: Through a built-in core pattern library, multiple silicon steel sheet patterns are preset for user selection; the feeding mechanism can automatically and synchronously adjust according to the width parameters, clamping and centering the silicon steel sheet, effectively preventing deviation and ensuring cutting accuracy. The control system coordinates the control of the feeding length and cutting position, enabling precise cutting of sheets of different lengths, demonstrating strong adaptability. Based on pattern library control, combined with an adjustable cutting mechanism and feeding mechanism, when changing products, the equipment can automatically adapt to the processing of various specifications of silicon steel sheets by selecting the corresponding pattern and parameters, significantly improving production flexibility.

[0008] According to some embodiments of the present invention, the silicon steel sheet processing equipment includes a material handling device and a linkage mechanism. The material handling device is located on the side of the second shearing unit away from the first shearing unit and is used to transport the silicon steel sheet cut by the shearing mechanism. The linkage mechanism connects the shearing mechanism and the material handling device, such that when the first driving device drives the shearing mechanism to move, the material handling device moves accordingly along the conveying direction of the silicon steel sheet. According to some embodiments of the present invention, the linkage mechanism includes a slide rail disposed on the shearing mechanism and a slider disposed on the material handling device. The arrangement direction of the slide rail is parallel to the arrangement direction of the second shearing unit. The slider and the slide rail are connected by a sliding pair that fits into each other. The sliding pair is configured to allow the slider to slide along the length direction of the slide rail and to restrict the slider from separating from the slide rail in a direction perpendicular to the length direction of the slide rail.

[0009] According to some embodiments of the present invention, the sliding pair includes a mating groove disposed on the slider and a limiting structure disposed on the slide rail, the mating groove having two opposing inner flanges, and the limiting structure being adapted to the mating groove.

[0010] According to some embodiments of the present invention, the linkage mechanism further includes a rotating shaft and a connecting rod.

[0011] According to some embodiments of the present invention, the first limiting module is fixedly connected to the base plate, and the second limiting module is connected to the linkage mechanism.

[0012] According to some embodiments of the present invention, the feeding mechanism further includes a third limiting module and a fourth limiting module. The first limiting module and the second limiting module are disposed behind the shearing mechanism. The third limiting module and the fourth limiting module are located between the first shearing unit and the second shearing unit. The third limiting module and the fourth limiting module are each provided with the limiting plate and are disposed opposite to each other. The third limiting module is fixedly connected to the base plate, and the fourth limiting module is connected to the base plate through a transmission mechanism. The transmission mechanism is used to adjust the fourth limiting module so that the third limiting module and the fourth limiting module synchronously move towards the theoretical center line of the silicon steel sheet or synchronously unfold in a direction away from the theoretical center line.

[0013] According to some embodiments of the present invention, the transmission mechanism includes a first rack, a gear, and a second rack, the first rack and the second rack respectively meshing on opposite sides of the gear, the first rack being fixedly connected to the base plate, the second rack being fixedly connected to the fourth limiting module, the center positioning shearing and stacking integrated machine including a worktable, the base plate being slidably connected to the worktable, and the gear being connected to the worktable.

[0014] According to some embodiments of the present invention, the first driving device includes a drive motor and a drive screw. The drive motor drives the drive screw to rotate, thereby driving the shearing mechanism to move. The feeding mechanism also includes a bidirectional screw, with the two ends of the bidirectional screw respectively connected to the first limiting module and the second limiting module. The driving device also includes a right-angle commutator, which connects the drive motor, the drive screw, and the bidirectional screw.

[0015] According to some embodiments of the present invention, the silicon steel sheet processing equipment further includes a stacking mechanism, which includes a stacking table, a plurality of second positioning rods, and a robot arm; the second positioning rods are used to position the silicon steel sheets and install them on the stacking table, the plurality of second positioning rods are arranged around the center of the stacking table, and the robot arm is used to transport the silicon steel sheets from the feeding mechanism to the stacking table; the control system is capable of selecting multiple silicon steel sheet patterns, inter-sheet overlap relationship parameters, and stacking layer combination sequence parameters, and then controlling the stacking mechanism to perform stacking.

The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0022] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0023] Reference Figure 1 , Figure 2 and Figure 3 The silicon steel sheet processing equipment includes an unwinding mechanism 600, a shearing mechanism 100, a first driving device 200, a feeding mechanism, and a control system. The above structures work together to automatically and continuously process the coiled silicon steel strip into sheets of specific shapes and sizes according to preset graphic requirements, providing precise blanks for subsequent iron core stacking processes.

[0024] The unwinding mechanism 600 is used to place silicon steel sheet coils. The shearing mechanism 100 is located behind the unwinding mechanism 600 and is used to shear the silicon steel sheet coils. The shearing mechanism 100 includes a base plate 110, a first shearing unit 120, and a second shearing unit 130. Exemplarily, both the first shearing unit 120 and the second shearing unit 130 include a blade holder. The blade holder is equipped with opposing moving shearing blades and fixed shearing blades, which form a shearing opening. A shearing drive device for driving the moving shearing blades is provided above the blade holder. The first shearing unit 120 and the second shearing unit 130 are arranged at intervals along the conveying direction of the silicon steel sheet and are fixedly mounted on the base plate 110. The arrangement directions of the first shearing unit 120 and the second shearing unit 130 intersect to form an included angle. This layout allows the shearing mechanism 100 to complete two shearing actions in different directions or shapes during one conveying of the strip, thereby processing complex sheet shapes (such as E-type, V-type, etc.) in one stroke, significantly improving processing efficiency and shape complexity.

[0025] Reference Figure 3 and Figure 4 The first driving device 200 drives the shearing mechanism 100 to move, and the moving direction of the shearing mechanism 100 is perpendicular to the conveying direction of the silicon steel sheet. For example, the first driving device 200 includes a drive motor 210 and a drive screw 220. The base plate 110 is provided with a threaded portion 111 that mates with the drive screw 220, and a guide groove 112 is provided on the lower side of the base plate 110. The shearing mechanism 100 is mounted on the worktable, and the guide groove 112 mates with the guide rail of the worktable. When the drive motor 210 drives the drive screw 220 to rotate, it will push the base plate 110 to move along the guide rail. Since the arrangement directions of the first shearing unit 120 and the second shearing unit 130 intersect to form an included angle, when the first driving device 200 drives the shearing mechanism 100 to move laterally to adjust its position, the size of the silicon steel sheet cut by the shearing mechanism 100 at different positions is also different, so as to adapt to the processing requirements of silicon steel sheets of different specifications.

[0026] Reference Figure 3 and Figure 8 The feeding mechanism includes a first limiting module 330 and a second limiting module 340, which are arranged opposite to each other. Both the first and second limiting modules 330 and 340 are equipped with limiting plates 331, and each limiting plate 331 has a limiting groove 332. The side of the silicon steel sheet is located within the limiting groove 332. The first and second limiting modules 330 and 340 restrict the left and right offset of the silicon steel sheet during the feeding process, ensuring the accuracy of the shearing position. The feeding mechanism also includes a synchronization mechanism, which can adjust the relative position of the first and second limiting modules 330 and 340, so that the first and second limiting modules 330 and 340 synchronously move towards the theoretical centerline of the silicon steel sheet or synchronously unfold in a direction away from the theoretical centerline. This ensures that the physical centerline of silicon steel strips of different widths is always aligned with the theoretical centerline of the equipment during feeding, achieving an "automatic centering" function and laying a benchmark for subsequent precise shearing.

[0027] The synchronization mechanism includes a bidirectional screw 360, with its two ends connected to a first limiting module 330 and a second limiting module 340, respectively. When the bidirectional screw 360 rotates, the first limiting module 330 and the second limiting module 340 move in opposite directions. If the screw rotates clockwise, the two modules move closer to each other; if it rotates counterclockwise, they move further apart. The first drive device 200 includes a right-angle commutator, which connects to a drive motor 210, a drive screw 220, and the bidirectional screw 360. When the drive motor 210 starts, it simultaneously drives the drive screw 220 and the bidirectional screw 360 to rotate together. Thus, when the shearing mechanism 100 moves to accommodate silicon steel sheets of different sizes, the first limiting module 330 and the second limiting module 340 also move synchronously along the arrangement direction of the two sides around the center of the silicon steel sheet, ensuring that each silicon steel sheet is precisely aligned with the preset center position.

[0028] By controlling only one drive motor 210, the two key adjustments of lateral positioning and limit channel width and center positioning of the shearing station can be completed simultaneously, which greatly reduces changeover time. While ensuring accuracy, it can avoid interference between mechanisms and improve production flexibility.

[0029] Understandably, the control system incorporates a core pattern library containing various silicon steel sheet patterns. The control system can select a particular pattern and adjust its width and shearing length parameters. Specifically, the control system controls the unwinding speed of the unwinding mechanism 600 based on the silicon steel sheet width parameter and the shearing length parameter, and also controls the first drive device 200 to drive the shearing mechanism 100 to move perpendicular to the conveying direction of the silicon steel sheet. By binding the pattern parameters, width parameters, and shearing length parameters to each actuator, automated production is achieved, reducing manual intervention while ensuring consistency in batch production. The pattern library design lowers the technical requirements for operators and improves the ease of use of the equipment.

[0030] The specific working process is as follows: The operator installs the silicon steel sheet roll onto the reel of the unwinding mechanism 600, ensuring the roll is firmly fixed and without deviation. Through the control system's operating interface, the operator selects the target silicon steel sheet graphic from the built-in iron core graphic library. Based on production requirements, two key parameters are input and confirmed in the control system: the silicon steel sheet width parameter (corresponding to the width dimension of the finished product) and the shearing length parameter (corresponding to the length dimension of the finished product). After receiving the width parameter, the control system sends a command to the synchronization mechanism of the feeding mechanism. The synchronization mechanism drives the first limit module 330 and the second limit module 340 to move synchronously: if the width parameter decreases, the two modules move closer together along the "theoretical center line of the silicon steel sheet"; if the width parameter increases, the two modules unfold in a direction away from the center line. After adjustment, the limit grooves 332 on the two limit modules form a channel adapted to the width of the silicon steel sheet, allowing the side of the silicon steel sheet to fit perfectly into the groove, completing the precise adjustment of the feeding channel. The control system calculates and sends an unwinding speed command to the unwinding mechanism 600 based on the shearing length parameter. The unwinding mechanism 600 then releases the silicon steel sheet roll at a uniform speed, and the silicon steel sheet is conveyed to the shearing mechanism 100 along the limiting groove 332 of the feeding mechanism. Simultaneously, the control system sends a movement command to the first driving device 200, driving the entire shearing mechanism 100 to move perpendicular to the silicon steel sheet conveying direction. When the silicon steel sheet is conveyed to the position of the shearing mechanism 100, the first shearing unit 120 and the second shearing unit 130 operate simultaneously at a preset angle to perform a single forming shear on the silicon steel sheet. After a single shear is completed, the unwinding mechanism 600 continues to feed at the set speed, and the shearing mechanism 100 resets under the drive of the first driving device 200 and prepares for the next shear, repeating this cycle until the entire roll of silicon steel sheet is processed.

[0031] In some embodiments, the shearing mechanism 100 can also adjust the shearing angle, and the shearing mechanism 100 operates according to preset graphic instructions. The shearing mechanism 100 no longer simply cuts out strips of fixed width, but can complete the punching and shearing of specific shapes in one action through its own motion trajectory or the cooperation of multi-station molds, and is suitable for shearing various shapes of graphics.

[0032] Reference Figure 5 and Figure 6 The silicon steel sheet processing equipment is also equipped with a material picking device 300. The material picking device 300 is located on the side of the second shearing unit 130 away from the first shearing unit 120. After shearing is completed, the material picking device 300 simultaneously receives the cut silicon steel sheet and moves it to the subsequent process (such as the stacking station) along the conveying direction.

[0033] Understandably, in the automated shearing and transfer production line of silicon steel sheets, the coordinated action of the shearing mechanism 100 and the material handling device 300 directly determines the production efficiency, equipment space occupation, and adaptability. Traditional equipment generally uses a V-shaped shearing mechanism 100, whose shearing trajectory overlaps with the conveying path of the material handling device 300. When processing silicon steel sheets of different widths, the movement of the shearing mechanism 100 can cause interference or increased gap with the material handling device 300. When processing longer silicon steel sheets, after the silicon steel sheet is conveyed to the shearing station and positioned, the material handling device 300 needs to retreat a preset distance in the opposite direction of the silicon steel sheet conveying to avoid the forward path of the shearing mechanism 100 and avoid collision with the shearing blade. After the material handling device 300 retreats to its position, the shearing mechanism 100 moves forward in a direction perpendicular to the silicon steel sheet conveying, and the silicon steel sheet is separated by the shearing force of the V-shaped blade. When processing shorter silicon steel sheets, the shearing mechanism 100 needs to retreat in a direction perpendicular to the silicon steel sheet conveying. After the shearing mechanism 100 has completely retreated, the gap between the shearing mechanism 100 and the material handling device 300 will increase, which is not conducive to the material handling device 300 receiving the sheared material.

[0034] The avoidance action requires additional mechanical movement space (including the retraction travel space of the material handling device 300 and the lateral movement space of the shearing mechanism 100), resulting in an increase in the overall size of the equipment and occupying more workshop space. Simultaneously, non-processing actions such as the retraction of the material handling device 300, the retraction of the shearing mechanism 100, and the mechanism reset are not performed simultaneously, consuming a significant amount of time and extending the single shearing cycle, making it difficult to improve production efficiency. Furthermore, the actions of the shearing mechanism 100 and the material handling device 300 have a strict time dependency (e.g., if the clamping retraction is not in place, the shearing mechanism 100 cannot start; if the shearing mechanism 100 is not reset, the material handling device 300 cannot move forward), requiring complex PLC control. Programming achieves time-series linkage, but inertial impacts and positional deviations during mechanical motion can easily lead to motion interference or timing disorder. When processing silicon steel sheets of different widths, the avoidance and retreat distance of the material handling device 300 and the lateral avoidance distance of the shearing mechanism 100 need to be recalculated and adjusted according to the size of the silicon steel sheet. This not only requires manual readjustment of equipment parameters, resulting in low equipment changeover efficiency, but also the variation in motion stroke under different widths further increases the complexity of timing control, which can easily lead to matching errors, resulting in problems such as out-of-tolerance shearing dimensions or material slippage.

[0035] To address the aforementioned problems, the silicon steel sheet processing equipment in this embodiment of the invention is further equipped with a linkage mechanism 400. The linkage mechanism 400 connects the shearing mechanism 100 and the material handling device 300. When the first driving device 200 drives the shearing mechanism 100 to move laterally, this lateral movement is converted through the linkage mechanism 400 and drives the material handling device 300 to move longitudinally (i.e., in the silicon steel sheet conveying direction). For example, when processing silicon steel sheets of greater length, the end with the larger gap between the first shearing unit 120 and the second shearing unit 130 needs to move towards the silicon steel sheet. If the material handling device 300 does not avoid this gap, interference will occur. However, under the action of the linkage mechanism 400, the material handling device 300 moves backward to avoid the gap while the larger end of the shearing mechanism 100 moves towards the silicon steel sheet, ensuring that the two remain closely adjacent. For example, when processing silicon steel sheets of shorter length, the smaller end of the first shearing unit 120 and the second shearing unit 130 needs to move towards the silicon steel sheet. If the material handling device 300 remains stationary, the distance between the shearing mechanism 100 and the material handling device 300 will increase, making it difficult for the material handling device 300 to grasp the sheared material. However, under the action of the linkage mechanism 400, the material handling device 300 moves forward to approach the material handling device 300 while the smaller end of the shearing mechanism 100 moves towards the silicon steel sheet, ensuring that the two are closely adjacent.

[0036] By setting up the linkage mechanism 400, the material handling device 300 can be placed close to the shearing station without requiring any clearance. Only one first drive device 200 is needed to perform shearing and material handling actions, eliminating the need for an additional material handling drive mechanism, reducing timing dependence and minimizing the risk of action interference. The first drive device 200 drives the shearing mechanism 100 to move, allowing the spacing between the first shearing unit 120 and the second shearing unit 130 to adapt to the range of silicon steel sheets of different widths. The travel distance of the material handling device 300 is limited by the linkage mechanism 400, eliminating the need for adjustment according to the width of the silicon steel sheet, thus improving changeover efficiency and eliminating the need for additional clearance adjustments.

[0037] Reference Figure 7 The linkage mechanism 400 includes a slide rail 410 and a slider 420. The slide rail 410 is disposed on the shearing mechanism 100, for example, on the base plate 110 or on the side of the housing of the second shearing unit 130. The arrangement direction of the slide rail 410 is parallel to the arrangement direction of the second shearing unit 130. The slider 420 is disposed on the material handling device 300. The slide rail 410 and the slider 420 cooperate with each other so that the relative movement between the material handling device 300 and the shearing mechanism 100 is along the arrangement direction of the second shearing unit 130, preventing the gap between the two from increasing or decreasing. The slider 420 and the slide rail 410 are connected by a mutually fitting sliding pair. The sliding pair is configured to allow the slider 420 to slide along the length direction of the slide rail 410 and to restrict the slider 420 from separating from the slide rail 410 in a direction perpendicular to the length direction of the slide rail 410. For example, the sliding pair can be a dovetail groove, a T-groove, or a ball bearing slide rail 410 structure.

[0038] When the first driving device 200 is activated, driving the shearing mechanism 100 to move laterally along the direction perpendicular to the silicon steel sheet conveying direction, the slide rail 410 fixed on it moves synchronously. Since the movement of the slider 420 in the axial direction perpendicular to the slide rail 410 is constrained, the lateral displacement of the slide rail 410 forces the slider 420 to generate a longitudinal displacement along the inclined trajectory of the slide rail 410 along the direction of silicon steel sheet conveying, which drives the material handling device 300 to complete the feeding action. Specifically, when the first driving device 200 drives the shearing mechanism 100 to move along the direction perpendicular to the silicon steel sheet conveying direction, enabling the shearing mechanism 100 to cut larger silicon steel sheets, the slide rail 410 moves synchronously with the shearing mechanism 100. Because the slider 420 is fixed on the material handling device 300, when the slide rail 410 moves downward, its interlocking structure with the slider 420 generates a horizontal component force, pushing the slider 420 to slide along the length direction of the slide rail 410, thereby causing the material handling device 300 to retreat in the opposite direction of silicon steel sheet conveying, avoiding the shearing area. When the first driving device 200 drives the shearing mechanism 100 to move in the opposite direction, making the shearing mechanism 100 suitable for cutting smaller silicon steel sheets, the slide rail 410 moves synchronously, and the interlocking structure of the sliding pair generates a reverse horizontal component force, pulling the slider 420 to slide in the opposite direction along the length of the slide rail 410, driving the material picking device 300 to move forward along the silicon steel sheet conveying direction, and accurately receiving the sheared silicon steel sheet.

[0039] Reference Figure 7 The sliding pair includes a mating groove 421 on the slider 420 and a limiting structure 411 on the slide rail 410. The mating groove 421 has two opposing inner flanges 422, and the limiting structure 411 is adapted to the mating groove 421. The mating groove 421 is located on the side of the slider 420 facing the slide rail 410 and is a groove-type structure. It has two opposing inner flanges 422 (i.e., protrusions formed by the inward extension of the two side walls of the groove, such as the two side flanges of a dovetail groove or the transverse flange of a T-shaped groove). The limiting structure 411 is a protrusion structure (such as a dovetail protrusion or a T-shaped protrusion) that is perfectly adapted to the shape of the mating groove 421. The two sides of the limiting structure 411 are in contact with the end faces of the inner flanges 422 of the mating groove 421 to form a sliding contact surface. The length of the limiting structure 411 is the same as the length of the slide rail 410, covering the entire sliding stroke of the slider 420. By embedding the limiting structure 411 of the slide rail 410 into the mating groove 421 of the slider 420, and with the two inner flanges 422 precisely positioned outside the neck or specific groove of the limiting structure 411, the constraint function of the sliding pair is achieved. The two inner flanges 422 effectively restrict the limiting structure 411 from disengaging from the mating groove 421, thereby preventing the slider 420 from separating from the slide rail 410 in a plane perpendicular to the sliding direction.

[0040] Reference Figure 7The linkage mechanism 400 also includes a rotating shaft 430 and a connecting rod 440. The slider 420 is connected to the material handling device 300 via the rotating shaft 430 and the connecting rod 440. One end of the connecting rod 440 is sleeved on the rotating shaft 430, that is, one end of the connecting rod 440 is sleeved on the rotating shaft 430 via a bearing or bushing, forming a rotatable hinged connection. This provides the necessary degrees of freedom of movement to compensate for minor deviations in the operation of the mechanism, ensuring smooth operation and reducing jamming. One of the rotating shaft 430 and the connecting rod 440 is located on the material handling device 300, and the other is located on the slider 420. That is, the rotating shaft 430 is fixed to the material handling device 300, and one end of the connecting rod 440 is hinged to the rotating shaft 430, while the other end is fixed to the slider 420. Alternatively, the rotating shaft 430 is fixed to the slider 420, one end of the connecting rod 440 is hinged to the rotating shaft 430, and the other end is fixed to the material handling device 300.

[0041] Reference Figure 5 and Figure 6 The material handling device 300 includes a first clamping mechanism 310 and a second clamping mechanism 320, which are spaced apart in the vertical direction. Both the first clamping mechanism 310 and the second clamping mechanism 320 are connected to the linkage mechanism 400. The first clamping mechanism 310 and the second clamping mechanism 320 respectively attach to the upper and lower parts of the silicon steel sheet to form a cooperative clamping posture. Through double-point clamping, the holding stability of the silicon steel sheet is greatly enhanced, effectively preventing the thin and wide silicon steel sheet from warping, sagging, or deviating during high-speed conveying, thus ensuring the positioning accuracy and reliability of the feeding process.

[0042] Reference Figure 5 The first clamping mechanism 310 includes a driven wheel 311 and a second driving device 312. The second driving device 312 drives the driven wheel 311 to move up and down. When it is necessary to clamp a silicon steel sheet, the second driving device 312 receives a command from the control system and drives the driven wheel 311 to move downward, pressing the silicon steel sheet below it. The cooperating second clamping mechanism 320 acts as a support surface, providing support from below. By controlling the downward pressure and stroke of the driven wheel 311, stable clamping of the silicon steel sheet is achieved. After the transfer task is completed, the second driving device 312 drives the driven wheel 311 to return upward, releasing the clamp.

[0043] Reference Figure 6The second clamping mechanism 320 includes a fixed support 321, a movable support 322, and a conveyor belt 323. The movable support 322 is movably arranged relative to the fixed support 321. Both the fixed support 321 and the movable support 322 are equipped with multiple guide rollers 324, and the conveyor belt 323 is mounted on the guide rollers 324, forming a closed conveying loop. The conveying device also includes a tensioning mechanism 325, which is used to adjust the tension of the conveyor belt 323. Because the movable support 322 needs to move, the actual effective length of the conveyor belt 323 will change. When the position of the movable support 322 is adjusted, the tensioning mechanism 325 tightens the conveyor belt 323 to prevent it from slack and slipping. Regardless of the position of the movable support 322, the conveyor belt 323 can be guaranteed to have appropriate tension, ensuring accurate transmission and avoiding deviation or vibration.

[0044] The movable support 322 can move relative to the fixed support 321 in a directional manner (sliding, rotating, or swinging), so that the conveying path of the conveyor belt 323 and the shearing trajectory of the shearing mechanism 100 form a dynamic avoidance relationship. Compared with the traditional "complete backward avoidance", the movable support 322 only needs to drive a small adjustment of part of the conveying structure to make room for the shearing mechanism 100, without interrupting the conveying preparation action, realizing the parallel operation of "shearing operation" and "conveying preparation", and significantly shortening the cycle time. The movable support 322 only supports part of the guide wheel 324 and the section of the conveyor belt 323, significantly reducing the volume and mass of the moving parts and greatly reducing inertial impact. The conveyor belt 323 is a complete closed loop. When the silicon steel sheet moves across the entire conveying surface, it is always supported by the guide wheel 324 below, completely eliminating the gap between the fixed part and the moving part, and fundamentally avoiding the conveying error caused by the gap.

[0045] The first clamping mechanism 310 and the second clamping mechanism 320 are not rigidly connected as a single unit. Instead, they are each independently connected to a linkage mechanism 400, avoiding the risk of torsional deformation or asynchrony that may occur when a large component is driven by a single mechanism. Because the first clamping mechanism 310 and the second clamping mechanism 320 move synchronously, they maintain a uniform and constant pressure on the silicon steel sheet during movement. This avoids the problems of uneven pressure or even warping at the front or rear end of the material that may occur due to single-point drive, making it particularly suitable for high-quality conveying of thin and wide silicon steel sheets.

[0046] Reference Figure 3 and Figure 4The first limiting module 330 is fixedly connected to the base plate 110, meaning it is fixed relative to the shearing mechanism 100 and moves with it. The second limiting module 340 is connected to the linkage mechanism 400 and moves synchronously with it. The following movement of the first limiting module 330 ensures that one side of the silicon steel sheet remains aligned with the shearing reference of the shearing mechanism 100 during the conveying process, preventing the limiting reference from shifting due to the movement of the shearing mechanism 100 and ensuring shearing position accuracy. The second limiting module 340 is not directly fixed to the shearing mechanism 100, but is connected to it through the linkage mechanism 400, thus maintaining a small gap with the shearing mechanism 100.

[0047] Reference Figure 9 and Figure 10 A third limiting module 370 and a fourth limiting module 380 are provided between the first shearing unit 120 and the second shearing unit 130. Both the third limiting module 370 and the fourth limiting module 380 are equipped with limiting plates 331, each with a limiting groove 332 for constraining the sides of the silicon steel sheet. The third limiting module 370 and the fourth limiting module 380 are arranged opposite to each other. The third limiting module 370 is fixedly connected to the base plate 110, meaning it is fixed relative to the shearing mechanism 100 and moves with it. When the first driving device 200 drives the shearing mechanism 100 to move, the third limiting module 370 will follow synchronously, always maintaining a constant relative position with the shearing blade, providing a stable unilateral positioning reference for the silicon steel sheet before shearing. The fourth limiting module 380 is connected to the base plate 110 through a transmission mechanism. The transmission mechanism is used to adjust the fourth limiting module 380. During the movement of the shearing mechanism 100, the fourth limiting module 380 and the third limiting module 370 maintain "synchronous approach" or "synchronous expansion", and the movement distance of the two is symmetrical about the theoretical center line of the silicon steel sheet, ensuring that the channel formed by the limiting groove 332 is always aligned with the center line.

[0048] The transmission mechanism includes a first rack 391, a gear 392, and a second rack 393. The first rack 391 is fixedly connected to the base plate 110, the second rack 393 is fixedly connected to the fourth limiting module 380, and the gear 392 is connected to the worktable. The first rack 391 and the second rack 393 are respectively meshed on opposite sides of the gear 392. When the base plate 110 moves, it drives the third limiting module 370 and the first rack 391 to move in the same direction. The gear 392 rotates under the drive of the first rack 391, thereby driving the second rack 393 to move in the opposite direction. The second rack 393 drives the fourth limiting module 380 to move in the same direction, thereby enabling the third limiting module 370 and the fourth limiting module 380 to move closer to or further away from each other, and to move the same distance, keeping the center position of the silicon steel sheet unchanged, and achieving the purpose of center positioning.

[0049] Reference Figure 1 , Figure 2 , Figure 11 and Figure 12 The silicon steel sheet processing equipment also includes a punching mechanism 700 and a stacking mechanism 800. The punching mechanism 700 punches holes in the silicon steel sheets. The feeding mechanism includes a magnetic conveyor belt, a feeding component 910, and multiple first positioning rods 920. The magnetic conveyor belt is positioned above the feeding component 910 to transport the sheared silicon steel sheets to the feeding component 910. The feeding component 910 can extend parallel to the orthogonal direction of the magnetic conveyor belt. The first positioning rods 920 are mounted on the feeding component 910 to position the silicon steel sheets. In this embodiment, the magnetic conveyor belt is equipped with magnets, allowing the silicon steel sheets to be attracted to the lower surface of the conveyor belt for transport. When the silicon steel sheets reach the designated stacking position, the magnet at that position can be raised, increasing the distance between the magnet and the lower surface of the conveyor belt. As the magnetic attraction weakens or even disappears, the silicon steel sheets fall freely into the feeding component 910 for stacking. The feeder 910 extends parallel to the orthogonal direction of the magnetic conveyor belt, its displacement direction perpendicular to the silicon steel sheet conveying direction. This allows it to accurately receive silicon steel sheets falling from the conveyor belt and, through its extension, transfer pre-positioned silicon steel sheets to the gripping area of ​​the robot 820, achieving seamless connection between the feeding end and the stacking mechanism 800. The stacking mechanism 800 also includes a stacking table 810, multiple second positioning rods, and the robot 820. The second positioning rods are used to position the silicon steel sheets and are mounted on the stacking table 810. Multiple second positioning rods are arranged around the center of the stacking table 810. The robot 820 is used to transport the silicon steel sheets from the feeder 910 to the stacking table 810. The robot 820 is equipped with an electro-permanent magnet for picking up the silicon steel sheets.

[0050] When the silicon steel sheet roll reaches the shearing mechanism 100 from the unwinding mechanism 600, it is sheared into the required silicon steel sheets and then transported to the feeding unit 910. The sheets are neatly stacked on the feeding unit 910 via the first positioning rod 920. When a certain number of silicon steel sheets are on the feeding unit 910, the feeding unit 910 extends, and the robotic arm 820 operates, using an electro-permanent magnet to remove all the silicon steel sheets from the feeding unit 910 at once and transport them to the stacking table 810. There, they are neatly stacked on the stacking table 810 via the second positioning rod. The first positioning rod 920 performs material handling in the buffer stage, and the second positioning rod provides hard positioning in the stacking stage, doubly ensuring the positional accuracy of each layer of silicon steel sheets and guaranteeing the integrity and consistency of the iron core.

[0051] The control system can select multiple silicon steel sheet patterns, inter-sheet overlap parameters, and stacking sequence parameters, and then control the stacking mechanism 800 to stack the sheets. For example, the pattern library will contain at least two different pattern data: "E-shaped sheet" and "I-shaped sheet". Understandably, the silicon steel sheet processing equipment also includes a punching mechanism; the punching mechanism is activated when processing "E-shaped sheets" and deactivated when processing "I-shaped sheets".

[0052] The control system generates a detailed production task list based on the "stack layer and combination sequence parameters." For example: layers 1-10: stack E-sheets; layer 11: stack I-sheets; layers 12-21: stack E-sheets... Based on the current task (e.g., "E-sheets needed"), the control system controls the shearing mechanism 100 to begin producing silicon steel sheets (E-sheets) of specific shapes, and buffers them onto the feeder 910 via a magnetic conveyor belt. Once a batch of E-sheets is ready, the control system controls the stacking mechanism 800 to operate: the control system logically sets the size and position of the "virtual mold" to be formed by the second positioning rod based on the "inter-sheet overlap relationship parameters" and the current sheet type. The control robot 820 uses an electro-permanent magnet to pick up the entire batch of E-sheets at once. The guide robot 820 precisely places the entire batch of E-sheets onto the stacking table 810 at the position defined by the second positioning rod. After one layer of E-sheets is stacked, the control system automatically checks the task list. If the next layer needs to be switched to I-pieces, the control system will immediately switch instructions: first, adjust the shearing unit to produce I-pieces, and then adjust the stacking mechanism 800 (for example, by changing the placement point of the robot arm 820) to adapt to the stacking requirements and overlap of the I-pieces. This cycle continues until all lamination layers of the entire core are completed.

[0053] Traditional equipment requires stopping to change molds or make complicated mechanical adjustments when producing different patterns. Since an iron core is usually formed by stacking multiple different patterns, traditional equipment needs to stop frequently to adjust parameters and test benchmarks when processing iron cores, resulting in low production efficiency.

[0054] The control system of this invention disassembles the overall structure of the iron core into a subdivided unit of "E-piece frame + I-piece crossbar". Operators only need to complete the adjustment of graphic selection, size parameters, stacking layers and combination sequence parameters in one go before production begins. This allows them to complete actions such as adjusting the feeding width, cutting and positioning to stacking sequence, reducing downtime for debugging during production and achieving high continuity and high efficiency in production from coiled material to finished iron core.

[0055] The feeding mechanism's synchronization mechanism automatically adjusts the first limit module 330 and the second limit module 340 according to the sheet width parameter to center each sheet. Regardless of the sheet shape, each sheet can obtain a precise reference during processing and transfer, laying the foundation for subsequent accurate stacking and avoiding downtime caused by manual recalibration due to size changes. Multiple shearing mechanisms 100 arranged at an angle are fixed on the same base plate 110 and driven by the control system for precise lateral movement. To process sheets of different lengths or shapes, there is no need to change the mold; simply change the shearing length parameter through the control system and instruct the first drive device 200 to move the entire shearing mechanism 100 to the new lateral coordinate.

[0056] When different specifications of iron cores need to be produced, only the combination and parameters of the disassembled patterns need to be changed in the control system, without stopping the machine to replace parts. The shearing mechanism 100 adjusts the parameters to adapt to the outline and size of the new pattern, the synchronous mechanism of the feeding mechanism automatically adjusts the limit spacing and maintains the same positioning reference, and the robot arm 820 of the stacking mechanism transports according to the center reference, without the need to set a separate transport program for each pattern.

[0057] This invention also provides a method for processing silicon steel sheets, applied to the aforementioned silicon steel sheet processing equipment, the method comprising: Step S100: Obtain the production instruction set containing the sheet shape graphic and size parameters.

[0058] The production instruction set includes parameters such as graphic type, silicon steel sheet width, shearing length, shearing angle, unwinding tension, and feeding speed.

[0059] Step S200: According to the production instruction set, control the unwinding speed of the unwinding mechanism, control the width adjustment of the feeding mechanism, and control the shearing mechanism to adjust the shearing length. The control system calculates the target positions of the first and second limit modules based on the width parameter, and the synchronization mechanism drives the first and second limit modules to move, remaining stationary after reaching the target position. The control system also calculates the unwinding speed of the unwinding mechanism based on the length parameter, and calculates the target position of the shearing mechanism based on the length parameter. The first drive device drives the shearing mechanism to move, remaining stationary after reaching the target position.

[0060] Step S300: Control the shearing mechanism to perform the shearing action.

[0061] According to the sheet pattern in the production instruction set, the conveyed strip is cut and punched to form individual silicon steel sheets. The formed individual silicon steel sheets are collected, sorted, and buffered to a preset quantity. The silicon steel sheets stacked on the feeder are counted, and when the number reaches the preset batch quantity, a batch ready signal is triggered.

[0062] Step S400: Control the stacking mechanism to transport and stack silicon steel sheets to the stacking station according to the stacking logic in the production instruction set to form an iron core.

[0063] The production instruction set also includes various silicon steel sheet patterns that make up the iron core, inter-sheet overlap parameters, stacking layers and combination sequence parameters. The current position of the silicon steel sheet stack on the buffer platform is obtained through machine vision or sensors, the feeding component is controlled to extend, and the stacking robot is controlled to use an electro-permanent magnet to pick up the whole batch of precisely positioned silicon steel sheets at once, and the whole batch of silicon steel sheets is transported to the stacking table.

[0064] Existing silicon steel sheet processing equipment generally suffers from the following problems: a lack of a unified parameter storage and retrieval mechanism. When producing complex cores composed of various silicon steel sheets of different shapes (such as E-sheets and I-sheets), operators must perform independent and tedious programming and equipment parameter settings for each sheet type. This not only leads to lengthy production preparation time but also frequently requires machine downtime for debugging when switching sheet types, severely restricting production efficiency and making it difficult to guarantee the relative positional accuracy of different sheet types during stacking.

[0065] To address the aforementioned problems, this invention provides an automated processing and stacking method for iron cores. The aim is to construct an integrated iron core graphic library, pre-store complete iron core production information, and automatically generate a set of production instructions driving the entire process on a flexible device capable of processing multiple graphics, by inputting or selecting production information once. This method enables the equipment to continuously and automatically complete the production, overlapping, stacking, and assembly of different silicon steel sheets required for the iron core, completely eliminating downtime for debugging during intermediate sheet type switching, thereby significantly improving production efficiency and product consistency.

[0066] One specific processing method includes: Step S110: Obtain the production instruction set, which includes the graphic type of the first type of silicon steel sheet and the second type of silicon steel sheet, the width parameter of the silicon steel sheet, the shearing length parameter, the shearing angle parameter, the unwinding tension parameter and the feeding speed parameter, the inter-sheet overlap relationship parameter, and the stacking layer and combination sequence parameter.

[0067] According to the silicon steel sheet width parameter, shearing length parameter, shearing angle parameter, unwinding tension parameter, feeding speed parameter, inter-sheet lap relationship parameter, and lamination level and combination sequence parameter of the first type of silicon steel sheet, steps S200 to S400 are executed. That is, according to all the parameters corresponding to the first type of silicon steel sheet in the production instruction set, the control system issues corresponding instructions to the unwinding mechanism, feeding mechanism, shearing mechanism, punching mechanism, and lamination mechanism. The processing equipment automatically completes the whole process from unwinding, centering, length setting, shearing, punching to sheet material buffering according to the issued parameters, and produces the required "E" - shaped sheets. The lamination mechanism (including manipulator, positioning rod, etc.) stacks the produced "E" - shaped sheets in a set number of layers and at a set angle according to the lamination level and combination sequence parameters in the instruction set. For example, first continuously stack several layers of "E" sheets to form the "mouth" - shaped main frame of the iron core.

[0068] According to the silicon steel sheet width parameter, shearing length parameter, shearing angle parameter, unwinding tension parameter, feeding speed parameter, inter - sheet lap relationship parameter, and lamination level and combination sequence parameter of the second type of silicon steel sheet, steps S200 to S400 are executed. That is, after stacking the preset number of the first type of silicon steel sheets, the control system automatically switches to the production instruction of the second type of silicon steel sheet. According to the parameters corresponding to the second type of silicon steel sheet in the production instruction set, the control equipment adjusts and starts to produce "I" - shaped sheets. At the preset layer position, it switches to stacking the second - shaped silicon steel sheets and precisely inserts the second - shaped silicon steel sheets into the space formed by the first - shaped silicon steel sheets. For example, precisely insert the "I" sheets as cross - bars into the space formed by the "E" sheets.

[0069] More specifically, the processing method includes: S1. Obtain a production instruction set, the production instruction set contains relevant parameters of at least the first type of silicon steel sheet and the second type of silicon steel sheet required for the target iron core, and the relevant parameters at least include: the graphic parameters of each silicon steel sheet, the processing technology parameters, and the stacking logic parameters defining how each silicon steel sheet is combined; S2. According to the relevant parameters corresponding to the first type of silicon steel sheet in the production instruction set, control the processing equipment to execute the first processing operation to produce and stack the first type of silicon steel sheet; S3. After completing the stacking of the preset number of the first type of silicon steel sheets, according to the relevant parameters corresponding to the second type of silicon steel sheet in the production instruction set, control the processing equipment to automatically switch and execute the second processing operation to produce the second type of silicon steel sheet, and stack it onto the already stacked first type of silicon steel sheet according to the stacking logic parameters to form a lap joint structure.

[0070] The processing parameters include at least one of the following: silicon steel sheet width, shearing length, shearing angle, unwinding tension, and feeding speed. The stacking logic parameters include inter-sheet overlap parameters, stacking layers, and combination sequence parameters. Step S2, "stacking the first type of silicon steel sheet," includes: continuously stacking multiple layers of the first type of silicon steel sheet to form the main frame of the iron core. Step S3, "forming an overlap structure," includes: inserting the second type of silicon steel sheet into the frame space formed by the first type of silicon steel sheet.

[0071] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
