[0002] In the automatic shearing and transferring production of silicon steel sheets, the traditional equipment adopts a V-shaped shearing mechanism. Because the shearing track and the transferring path of the clamping mechanism overlap in space, the two need to perform step-by-step avoidance actions: the clamping mechanism first retreats in the opposite direction of the conveying to avoid, the V-shaped shearing mechanism vertically descends to complete shearing, then needs to ascend and laterally move to avoid, and finally the clamping mechanism advances to clamp and transfer, and the shearing mechanism resets to prepare for the next cycle.

[0003] This mode has the following defects: first, the avoidance actions occupy a large amount of time, reducing production efficiency; second, in order to avoid interference between the two, a larger safety distance needs to be additionally reserved, resulting in an increase in the size of the equipment; third, the timing of the shearing and clamping mechanisms is strictly dependent, and the coordination control is complicated, which easily affects the processing precision due to action interference or deviation; fourth, the adaptability is poor, and when processing silicon steel sheets of different widths, the avoidance distances of the two need to be separately adjusted, resulting in low changeover efficiency.

[0025] In the automatic shearing and transferring production line of silicon steel sheets, the cooperation of the shearing mechanism and the clamping mechanism directly determines the production efficiency, equipment space occupation and adaptability. The traditional equipment generally adopts a V-shaped shearing mechanism, and the shearing motion track of the V-shaped shearing mechanism and the transferring path of the clamping mechanism overlap in space, so that the two must adopt a "step action" mode: after the silicon steel sheet is conveyed to the shearing station and positioned, the clamping mechanism needs to retreat a preset distance in the opposite direction of the silicon steel sheet conveying to avoid the advancing shearing space of the V-shaped shearing mechanism, so as to avoid the collision between the clamping jaw and the shearing blade. After the clamping mechanism retreats to the position, the V-shaped shearing mechanism moves forward horizontally in the direction perpendicular to the silicon steel sheet conveying, and the shearing force of the V-shaped blade realizes the separation of the silicon steel sheet. After the shearing is completed, the V-shaped shearing mechanism needs to move upward along the original path to retreat to the initial position to further avoid the advancing path of the subsequent clamping mechanism. After the shearing mechanism completely retreats, the clamping mechanism advances in the conveying direction, clamps the sheared silicon steel sheet and transfers it to the lamination station, and then the clamping mechanism resets and the shearing mechanism adjusts the position to the shearing origin again to complete a cycle.

[0026] The avoidance action needs to reserve additional mechanical motion space (including the retreat stroke space of the clamping mechanism and the side movement space of the shearing mechanism), which leads to the increase of the overall volume of the equipment and the occupation of more workshop space. At the same time, a large amount of time is occupied by non-processing actions such as clamping retreat, shearing retreat and mechanism reset, which prolongs the single shearing cycle period and makes it difficult to improve the production efficiency. The actions of the shearing mechanism and the clamping mechanism have strict time sequence dependence (for example, the shearing mechanism cannot start if the clamping retreat is not in place, and the clamping mechanism cannot advance if the shearing mechanism is not reset), which needs to be realized through complex PLC programming. Inertia impact and position deviation in the process of mechanical motion are easy to cause action interference or time sequence disorder. When processing silicon steel sheets of different widths, the retreat distance of the clamping mechanism and the side movement avoidance distance of the shearing mechanism need to be recalculated and adjusted according to the size of the silicon steel sheet. Not only does this require manual adjustment of equipment parameters, which leads to low equipment change efficiency, but also the change of action stroke under different widths further increases the complexity of time sequence control, which is easy to cause matching errors and lead to problems such as shearing size out-of-tolerance or clamping falling off.

[0027] The shearing and material taking assembly of the present application embodiment will be described below with reference to Figures 1 to 7 .

[0028] Reference is made to Figure 1 and Figure 2, the shearing and taking assembly comprises a shearing device 100, a first driving device 200, a taking device 300 and a linkage mechanism 400, the shearing device 100 comprises a bottom plate 110, a first shearing mechanism 120 and a second shearing mechanism 130, and the first shearing mechanism 120 and the second shearing mechanism 130 both comprise a knife holder, and the knife holder is provided with opposite movable shearing knives and fixed shearing knives, the movable shearing knives and the fixed shearing knives form a shearing gap, and a shearing driving device is arranged above the knife holder to drive the movable shearing knives. The first shearing mechanism 120 and the second shearing mechanism 130 are arranged in parallel along the conveying direction of the silicon steel sheet and are fixedly arranged on the bottom plate 110, that is, the silicon steel sheet passes through the first shearing mechanism 120 first and then passes through the second shearing mechanism 130. The arrangement directions of the first shearing mechanism 120 and the second shearing mechanism 130 intersect to form an included angle, and the first shearing mechanism 120 and the second shearing mechanism 130 are operated simultaneously during shearing, so that the silicon steel sheet with a predetermined shape is sheared.

[0029] With reference to Figure 2 The first driving device 200 is used for driving the shearing device 100 to move, and the moving direction of the shearing device 100 is perpendicular to the conveying direction of the silicon steel sheet. For example, the first driving device 200 comprises a driving motor 210 and a driving screw 220, the bottom plate 110 is provided with a threaded portion 111 matched with the driving screw 220, and the lower side of the bottom plate 110 is provided with a guide groove 112. The shearing device 100 is installed on a workbench, the guide groove 112 is matched with a guide rail of the workbench, when the driving motor 210 drives the driving screw 220 to rotate, the bottom plate 110 is pushed to move along the guide rail. Since the arrangement directions of the first shearing mechanism 120 and the second shearing mechanism 130 intersect to form an included angle, when the first driving device 200 drives the shearing device 100 to move transversely to adjust the position, the size of the silicon steel sheet sheared by the shearing device 100 at different positions is also different, so as to adapt to the processing requirements of silicon steel sheets with different specifications.

[0030] With reference to Figure 1The taking device 300 is located on the side of the second shearing mechanism 130 away from the first shearing mechanism 120. After shearing is completed, the taking device 300 synchronously receives the cut-off silicon steel sheet and moves it to the subsequent process (such as a lamination station) along the conveying direction. The linkage mechanism 400 mechanically connects the shearing device 100 and the taking device 300. When the first driving device 200 drives the shearing device 100 to move laterally, this lateral movement is converted by the linkage mechanism 400 and drives the taking device 300 to move longitudinally (i.e., in the conveying direction of the silicon steel sheet). For example, when a silicon steel sheet with a larger length needs to be processed, the large end of the interval between the first shearing mechanism 120 and the second shearing mechanism 130 needs to move towards the silicon steel sheet. If the taking device 300 does not avoid, interference will occur. Under the action of the linkage mechanism 400, the taking device 300 will move backward to avoid while the large end of the shearing device 100 moves towards the silicon steel sheet, ensuring that the two are closely adjacent. For another example, when a silicon steel sheet with a smaller length needs to be processed, the small end of the interval between the first shearing mechanism 120 and the second shearing mechanism 130 needs to move towards the silicon steel sheet. If the taking device 300 remains stationary, the distance between the shearing device 100 and the taking device 300 will increase, which is not conducive to the taking device 300 to grab the sheared material. Under the action of the linkage mechanism 400, the taking device 300 will move forward to approach the taking device 300 while the small end of the shearing device 100 moves towards the silicon steel sheet, ensuring that the two are closely adjacent.

[0031] By setting the linkage mechanism 400, the taking device 300 can be closely adjacent to the shearing station without needing to reserve an avoidance space. Only one first driving device 200 is needed to realize the shearing and taking actions, without the need to additionally set a taking driving mechanism, reducing timing dependence and reducing the risk of action interference. The first driving device 200 drives the shearing device 100 to move, so that the interval between the first shearing mechanism 120 and the second shearing mechanism 130 adapts to the range of different width silicon steel sheets. The movement stroke of the taking device 300 is defined by the linkage mechanism 400 and does not need to be adjusted with the width of the silicon steel sheet, improving the changeover efficiency and eliminating the need for additional debugging of avoidance distance.

[0032] Referring to Figure 5The linkage mechanism 400 includes a slide rail 410 and a slider 420. The slide rail 410 is mounted on the shearing device 100, for example, on the base plate 110 or on the side of the housing of the second shearing mechanism 130. The arrangement direction of the slide rail 410 is parallel to the arrangement direction of the second shearing mechanism 130. The slider 420 is mounted 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 device 100 is along the arrangement direction of the second shearing mechanism 130, preventing the gap between them from increasing or decreasing. The slider 420 and the slide rail 410 are connected by a sliding pair that fits together. 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.

[0033] When the first driving device 200 is activated, driving the shearing device 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 device 100 to move along the direction perpendicular to the silicon steel sheet conveying direction, enabling the shearing device 100 to cut larger silicon steel sheets, the slide rail 410 moves synchronously with the shearing device 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 device 100 to move in the opposite direction, making the shearing device 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.

[0034] Reference Figure 5The sliding pair comprises a matching groove 421 provided on the sliding block 420 and a limiting structure 411 provided on the sliding rail 410. The matching groove 421 has two opposite inner flanges 422, and the limiting structure 411 is adapted to the matching groove 421. The matching groove 421 is provided on the side of the sliding block 420 facing the sliding rail 410, and has a groove structure with two opposite inner flanges 422 (i.e. a protruding structure formed by extending the two side walls of the groove inward, such as the two side flanges of a dovetail groove or the horizontal flange of a T-shaped groove). The limiting structure 411 is a protruding structure (such as a dovetail-shaped protrusion or a T-shaped protrusion) completely adapted to the shape of the matching groove 421. The two side surfaces of the limiting structure 411 are in contact with the end surfaces of the inner flanges 422 of the matching groove 421 to form a sliding contact surface, and the length of the limiting structure 411 is consistent with the length of the sliding rail 410, covering the entire sliding stroke of the sliding block 420. By embedding the limiting structure 411 of the sliding rail 410 into the matching groove 421 of the sliding block 420, the two inner flanges 422 are just clamped outside the neck or a specific groove of the limiting structure 411, thereby realizing the constraint function of the sliding pair. The two inner flanges 422 effectively limit the limiting structure 411 from coming out of the matching groove 421, thereby preventing the sliding block 420 and the sliding rail 410 from separating in a plane perpendicular to the sliding direction.

[0035] With reference to Figure 5 The linkage mechanism 400 further comprises a rotating shaft 430 and a connecting rod 440. The sliding block 420 is connected to the material taking device 300 through the rotating shaft 430 and the connecting rod 440. One end of the connecting rod 440 is sleeved on the rotating shaft 430, i.e. one end of the connecting rod 440 is sleeved on the rotating shaft 430 through a bearing or a shaft sleeve to form a rotatable hinged connection, thereby providing the necessary degree of freedom of movement to compensate for slight deviations in the operation of the mechanism, ensuring smooth action and reducing jamming. One of the rotating shaft 430 and the connecting rod 440 is arranged on the material taking device 300, and the other is arranged on the sliding block 420. That is, the rotating shaft 430 is fixed on the material taking device 300, and one end of the connecting rod 440 is hinged to the rotating shaft 430, and the other end is fixedly connected to the sliding block 420. Alternatively, the rotating shaft 430 is fixed on the sliding block 420, and one end of the connecting rod 440 is hinged to the rotating shaft 430, and the other end is fixedly connected to the material taking device 300.

[0036] With reference to Figure 3 and Figure 4The taking device 300 comprises a first clamping mechanism 310 and a second clamping mechanism 320, which are arranged in a vertical direction and connected to the linkage mechanism 400. The first clamping mechanism 310 and the second clamping mechanism 320 are respectively attached to the upper and lower parts of the silicon steel sheet, forming a cooperative clamping posture. Through the double-point clamping, the holding stability of the silicon steel sheet is greatly enhanced, effectively preventing the silicon steel sheet from warping, sagging or deviating during high-speed conveying, and ensuring the positioning accuracy and reliability of the feeding process.

[0037] With reference to Figure 3 and Figure 6 , the first clamping mechanism 310 comprises a driven wheel 311 and a second driving device 312 for driving the driven wheel 311 to move up and down. When it is necessary to clamp the silicon steel sheet, the second driving device 312 receives the instruction of the control system and drives the driven wheel 311 to move downward to press the silicon steel sheet located below. The second clamping mechanism 320 cooperates as a supporting surface to provide support from below. By controlling the pressing force 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 to release the clamping.

[0038] With reference to Figure 4 and Figure 6 , the second clamping mechanism 320 comprises a fixed support 321, a movable support 322 and a conveying belt 323, and the movable support 322 is movably arranged relative to the fixed support 321. The fixed support 321 and the movable support 322 are both provided with a plurality of guide wheels 324, and the conveying belt 323 is installed on the guide wheels 324, i.e. the conveying belt 323 is arranged around the plurality of guide wheels 324 to form a closed conveying loop. The conveying device further comprises a tensioning mechanism 325 for adjusting the tension of the conveying belt 323. Since the movable support 322 needs to move, the actual effective length of the conveying belt 323 will change. After the position of the movable support 322 is adjusted, the conveying belt 323 is pulled tight by the tensioning mechanism 325 to prevent it from loosening and slipping. Regardless of the position of the movable support 322, the conveying belt 323 can have appropriate tension to ensure accurate transmission and avoid deviation or shaking.

[0039] The movable support 322 can move in orientation (slide, rotate or swing) relative to the fixed support 321, so that the conveying path of the conveying belt 323 forms a dynamic avoidance relationship with the shearing trajectory of the shearing mechanism. Compared with the traditional "full retreat avoidance", the movable support 322 only needs to drive part of the conveying structure to make a small adjustment, so as to provide a working space for the shearing mechanism, without interrupting the conveying preparation action, realizing the parallel of "shearing operation" and "conveying preparation" part of the action, greatly shortening the cycle period. The movable support 322 only bears part of the guide wheel 324 and the section of the conveying belt 323, the volume and mass of the moving part are significantly reduced, and the inertial impact is greatly reduced. The conveying belt 323 is a complete closed loop, and there is always a guide wheel 324 supporting below when the silicon steel sheet moves on the entire conveying surface, completely eliminating the gap between the fixed part and the movable part, and fundamentally avoiding the conveying error caused by the gap.

[0040] The first clamping mechanism 310 and the second clamping mechanism 320 are not rigidly connected as a whole. On the contrary, they are each independently connected to a linkage mechanism 400, avoiding the risk of torsional deformation or asynchronization that may be caused by driving a large assembly with a single mechanism. Since the first clamping mechanism 310 and the second clamping mechanism 320 move synchronously, uniform and constant pressure is maintained on the silicon steel sheet at all times during movement. This avoids the problem of uneven pressure on the front or back end of the material that may be caused by single-point driving, even warping, and is particularly suitable for high-quality conveying of thin and wide silicon steel sheets.

[0041] Referring to Figure 1 and Figure 6 The taking device 300 further comprises a limiting mechanism, the limiting mechanism is provided with a limiting groove 332, the side edge of the silicon steel sheet is located in the limiting groove 332, and the limiting mechanism is connected to the linkage mechanism 400. The limiting groove 332 is an elongated guide channel, the width of which matches the thickness of the silicon steel sheet and is slightly larger than the thickness of the silicon steel sheet to provide a small gap, and the side edge of the silicon steel sheet is constrained in the limiting groove 332. The function of the limiting groove 332 is to accurately guide the silicon steel sheet into the taking station, ensure that the side edge always runs along the predetermined reference line, and prevent deviation caused by accumulated errors or external interference.

[0042] The traditional fixed side edge limiting has a large spacing between the silicon steel sheet and the groove wall during feeding, which is prone to inaccurate alignment, especially for thin and wide silicon steel sheets, the problem is more serious. The limiting mechanism of the present application is connected to the linkage mechanism 400 to realize dynamic accurate guidance, greatly reducing the risk of wear and scratch, and the guiding effect is better. It provides a continuous lateral positioning reference for the high-speed feeding process, effectively resists any interference force that may cause the silicon steel sheet to deviate, ensures the repeated positioning accuracy of the transfer end, and lays a foundation for the accuracy of the subsequent lamination process.

[0043] Referring to Figure 1 andFigure 6 The limiting mechanism comprises an adjusting module 350, a first limiting module 330 and a second limiting module 340. The first limiting module 330 and the second limiting module 340 are both provided with a limiting plate 331, and a limiting groove 332 is arranged on the limiting plate 331. The first limiting module 330 and the second limiting module 340 are oppositely arranged. The first limiting module 330 is fixedly connected to the bottom plate 110, that is, the first limiting module 330 is fixed relative to the shearing device 100 and moves with the shearing device 100. The second limiting module 340 is connected to the linkage mechanism 400 and moves synchronously with the linkage mechanism 400. The adjusting module 350 is used to push the limiting plate 331 to move perpendicularly to the conveying direction of the silicon steel sheet, so that the distance between the first limiting module 330 and the second limiting module 340 matches the width of the silicon steel sheet. When the silicon steel sheets with different widths need to be processed, the adjusting module 350 is operated. The adjusting module 350 pushes the limiting plate 331 of the first limiting module 330 or the second limiting module 340 to change the relative distance between the two limiting plates 331, so that the limiting grooves 332 formed by the two limiting plates 331 accurately match the width of the new silicon steel sheet.

[0044] Referring to Figure 1 and Figure 2 The limiting mechanism further comprises a bidirectional screw rod 360. Two ends of the bidirectional screw rod 360 are respectively connected to the first limiting module 330 and the second limiting module 340. When the bidirectional screw rod 360 rotates, the first limiting module 330 and the second limiting module 340 move in opposite directions. If the screw rod rotates clockwise, the two modules move closer to each other; if the screw rod rotates counterclockwise, the two modules move away from each other. The first driving device 200 comprises a right-angle commutator. The right-angle commutator is connected to a driving motor 210, a driving screw rod 220 and the bidirectional screw rod 360. When the driving motor 210 is started, the driving screw rod 220 and the bidirectional screw rod 360 are simultaneously driven to rotate, so that when the shearing device 100 is driven to move to adapt to silicon steel sheets with different sizes, the limiting mechanism also moves synchronously along the arrangement direction of the two sides with the center of the silicon steel sheet, ensuring that each silicon steel sheet can be accurately aligned with the preset center position.

[0045] By controlling only one driving motor 210, the two key adjustments of transverse positioning of the shearing station and width and center positioning of the limiting channel can be simultaneously completed, which greatly reduces the changeover time, avoids interference between mechanisms while ensuring accuracy, and improves production flexibility.

[0046] Referring to Figure 7 and Figure 8The auxiliary feeding mechanism is arranged between the first shearing mechanism 120 and the second shearing mechanism 130, and comprises a lower conveying assembly 510 and a guide assembly 520 arranged above the lower conveying assembly 510, the lower conveying assembly 510 comprises a conveying motor and a conveying wheel, the conveying wheel is connected with the output end of the conveying motor, the guide assembly 520 comprises a guide wheel, and a feeding channel for the silicon steel sheet is arranged between the conveying wheel and the guide wheel. When the silicon steel sheet is sent into the area of the shearing device 100, the conveying motor drives the conveying wheel to rotate, the silicon steel sheet is continuously conveyed forward by the friction force, and the silicon steel sheet is conveniently grabbed by the taking device 300. The guide wheel provides necessary pressing force, ensures that there is enough friction force between the silicon steel sheet and the conveying wheel, and prevents the material from being lifted.

[0047] Referring to Figure 7 and Figure 8 The third limiting module 370 and the fourth limiting module 380 are oppositely arranged, the third limiting module 370 is fixedly connected to the bottom plate 110, that is, the third limiting module 370 is fixed relative to the shearing device 100 and moves with the shearing device 100. The fourth limiting module 380 is connected to the bottom plate 110 through a transmission mechanism. The transmission mechanism comprises a first rack 391, a gear 392 and a second rack 393, the first rack 391 is fixedly connected with the bottom plate 110, the second rack 393 is fixedly connected with the fourth limiting module 380, and the gear 392 is connected with the workbench. The first rack 391 and the second rack 393 are respectively engaged on opposite sides of the gear 392, when the bottom plate 110 moves, the third limiting module 370 and the first rack 391 move in the same direction, the gear 392 rotates under the drive of the first rack 391, and then drives the second rack 393 to move in the opposite direction, the fourth limiting module 380 moves in the same direction under the drive of the second rack 393, so that the third limiting module 370 and the fourth limiting module 380 are close to or away from each other, the moving distance is the same, the center position of the silicon steel sheet is kept unchanged, and the center positioning purpose is achieved.

[0048] The silicon steel sheet processing equipment of the second aspect embodiment of the present application comprises the silicon steel sheet shearing and taking assembly of the first aspect embodiment of the present application. By adopting the silicon steel sheet shearing and taking assembly of the first aspect embodiment of the present application, unnecessary waiting and idle time can be reduced, the equipment volume is reduced, the shearing and taking actions are not easy to interfere, and when processing silicon steel sheets of different widths, the type changing efficiency is improved.

[0049] The embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited to the above-described embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present application.
