Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, specifically to a truss rotor silicon steel sheet stacking and loading / unloading mechanism and operating method. Background Technology

[0002] This invention relates to the field of automated equipment technology for motor manufacturing, specifically to a truss rotor silicon steel sheet stacking and loading / unloading device and its operation method, which is corely applied to the precise stacking and automated loading / unloading process of rotor silicon steel sheets.

[0003] The lamination process of silicon steel sheets for rotors is a core step in motor core manufacturing. The lamination precision and uniformity of the silicon steel sheets directly determine the magnetic flux density of the core, which in turn affects the motor's magnetic properties, operating efficiency, mechanical strength, and heat dissipation, ultimately impacting the overall quality and lifespan of the motor product. With the surge in demand for high-efficiency motors in fields such as new energy vehicles and industrial motors, the market has placed higher demands on the precision, production efficiency, and automation of silicon steel sheet lamination. Traditional lamination and loading / unloading methods are no longer sufficient to meet the needs of large-scale, high-precision production.

[0004] The existing technologies for silicon steel sheet stacking and loading / unloading mainly suffer from the following defects: First, the degree of automation is low. Some processes rely on manual assistance for positioning, replenishment, and sheet counting, which not only results in high labor intensity and low production efficiency but also easily leads to stacking misalignment and sheet count deviation due to human error, affecting the consistency of the iron core. Second, the clamping and stacking mechanisms are poorly compatible. Traditional clamps have fixed dimensions, making it difficult to accommodate silicon steel sheets of different rotor specifications. Furthermore, the lack of an effective positioning and limiting structure during the stacking process makes it easy for silicon steel sheets to shift or tilt, reducing stacking accuracy. Third, the connection between loading / unloading and inspection is disconnected. After stacking, manual sampling inspection is often relied upon, or there is no effective sheet count verification mechanism. It is impossible to provide real-time feedback on stacking quality, and unqualified products flowing into subsequent processes can easily lead to resource waste. Fourth, the design of the drive and transmission structure is unreasonable. Some equipment can only achieve unidirectional movement, resulting in poor continuity of clamping, transfer, and stacking actions, further restricting the improvement of production efficiency.

[0005] Therefore, developing a truss rotor silicon steel sheet stacking and loading / unloading device with a high degree of automation, precise stacking, strong adaptability, and real-time sheet count verification capability to solve problems such as insufficient positioning accuracy, poor automation connection, and lack of sheet count verification in existing technologies has become an urgent technical need in this field.

[0007] Therefore, the purpose of this invention is to provide a truss rotor silicon steel sheet stacking and loading / unloading mechanism and operating method to solve the problems mentioned in the background art.

[0008] To address the aforementioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: A truss rotor silicon steel sheet stacking and loading / unloading device includes a truss body, a drive assembly disposed on the truss body, a stacking mechanism and a conveying mechanism connected to the drive assembly; It also includes silicon steel sheet storage racks, temporary storage and transfer mechanisms, inspection mechanisms, and unloading platforms; The driving component is used to drive the stacking mechanism and the conveying mechanism to move along the X-axis.

[0010] As a preferred embodiment of the truss rotor silicon steel sheet stacking and loading / unloading device of the present invention, the stacking mechanism includes a first Y and Z dual-axis moving assembly, a horizontal rotating seat disposed at the bottom of the first Y and Z dual-axis moving assembly, a first guide sliding seat symmetrically disposed at the bottom of the horizontal rotating seat, two first sliding plates sliding along the first guide sliding seat, a first lead screw assembly passing through the two first sliding plates and driving the two first sliding plates to move closer or further apart, a first gripper disposed at both ends of the first sliding plate, and a material detection element.

When the gripper cylinder retracts, it drives the gripper hook to clamp, and when it extends, it drives the gripper hook to open.

[0012] As a preferred embodiment of the truss rotor silicon steel sheet stacking and loading / unloading device of the present invention, the first Y and Z dual-axis moving assembly is provided with a horizontal rotation drive motor, the output end of the horizontal rotation drive motor is provided with a second gear, the top of the horizontal rotating seat is provided with a transmission shaft, and the transmission shaft is provided with a third gear that meshes with the second gear.

[0014] As a preferred embodiment of the truss rotor silicon steel sheet stacking and loading / unloading device of the present invention, the silicon steel sheet storage rack is provided with positioning cylinders around its perimeter for position correction of the silicon steel sheets.

[0015] As a preferred embodiment of the truss rotor silicon steel sheet stacking and loading / unloading device of the present invention, the temporary storage and transfer mechanism includes a transfer seat, a guide column disposed on the top of the transfer seat and having a guide rod and a protrusion, a bearing seat sleeved on the guide column and sliding along the guide rod, and a third lead screw assembly disposed at the bottom of the transfer seat for driving the bearing seat to slide along the guide rod.

[0016] As a preferred embodiment of the truss rotor silicon steel sheet stacking and loading / unloading device of the present invention, the inspection mechanism is equipped with a weighing unit to verify the actual number of silicon steel sheet stacks by weight measurement and to provide feedback on the verification results.

[0017] An operation method for a truss rotor silicon steel sheet stacking and loading / unloading device, comprising the following steps: S1. After the equipment is initialized, the silicon steel sheet is fed into the silicon steel sheet storage rack equipped with a positioning cylinder. The positioning cylinder extends to correct the position of the silicon steel sheet and retracts after the correction is completed. S2. The drive assembly moves the stacking mechanism to the silicon steel sheet storage rack. After the material detection component of the stacking mechanism confirms the position of the silicon steel sheet, its first lead screw assembly drives the first slide plate to adjust the spacing. The gripper cylinder drives the gripper hook to clamp the silicon steel sheet. Through the coordinated action of the first Y and Z dual-axis moving assembly and the horizontal rotating seat, the silicon steel sheet is transferred to the guide column and protrusion of the temporary storage transfer mechanism for precise placement. The gripping, transfer and placement actions are repeated until the target number of stacked sheets is completed. S3. The third lead screw assembly of the temporary storage and transfer mechanism drives the bearing seat to slide upward along the guide rod, lifting the silicon steel sheet group to a preset height; the drive assembly drives the handling mechanism to move below the temporary storage and transfer mechanism, and its second lead screw assembly drives the second slide plate to approach, and the hook block of the second gripper clamps the silicon steel sheet group from the bottom. It is then transferred to the inspection mechanism equipped with a weighing unit through the second Y and Z dual-axis moving assembly. The inspection mechanism verifies the number of stacked sheets by weight measurement and reports the result. If the verification is qualified, the handling mechanism transfers the silicon steel sheet group to the unloading platform and releases it to complete the unloading. If it is unqualified, an abnormal prompt is triggered. S4. After all operations are completed, the drive component, stacking mechanism, conveying mechanism and temporary storage transfer mechanism are reset to their initial positions and enter the next cycle to realize automatic loading and unloading and precise stacking of silicon steel sheets.

[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. Through the coordinated design of the truss main body, drive components, stacking mechanism, handling mechanism and various auxiliary mechanisms, the entire process of silicon steel sheet operation is automated from storage and positioning, grabbing and stacking, temporary storage and lifting, inspection and verification to unloading. No manual intervention is required for positioning, counting and transfer, which greatly reduces labor intensity, avoids human operation error, and improves production continuity and large-scale production capacity.

[0019] 2. The positioning cylinder of the silicon steel sheet storage rack can pre-position and correct the silicon steel sheets. The guide column and protrusion of the temporary storage and transfer mechanism form a precise limiting structure. With the coordinated action of the first Y and Z dual-axis moving components of the stacking mechanism and the horizontal rotating seat, the silicon steel sheets are aligned and stacked one by one, effectively improving the neatness of the stacking. At the same time, the weighing unit of the inspection mechanism verifies the number of stacked sheets in real time through weight measurement to avoid sheet number deviation. From the dual dimensions of stacking accuracy and quantity, the magnetic properties, mechanical strength and heat dissipation efficiency of the motor core are guaranteed.

[0020] 3. The stacking mechanism drives the first slide plate to adjust the spacing through the first lead screw assembly, and cooperates with the gripper cylinder to drive the hook to achieve the gripping action, which can flexibly adapt to rotor silicon steel sheets of different sizes; the second lead screw assembly and the hook block design of the second gripper of the conveying mechanism can stably clamp silicon steel sheet groups of different thicknesses without the need to replace special fixtures, reducing equipment adaptation costs and expanding the application range of products.

[0021] 4. The drive assembly adopts gear and rack meshing transmission. Both the stacking mechanism and the conveying mechanism are equipped with lead screw assembly and dual-axis moving assembly, which have high transmission accuracy and rapid response, ensuring smooth and continuous movement and clamping actions of each mechanism. The third lead screw assembly of the temporary storage and transfer mechanism drives the lifting and lowering of the carrier seat, realizing seamless connection between stacking and transfer, reducing process waiting time, and significantly improving overall production efficiency.

Detailed Implementation

[0023] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0024] Figures 1-7 The diagram shown is a structural schematic of one embodiment of a truss rotor silicon steel sheet stacking and loading / unloading device according to the present invention. Please refer to [link / reference]. Figures 1-7The truss rotor silicon steel sheet stacking and loading / unloading device of this embodiment includes a truss body 100, a drive assembly 200, a stacking mechanism 300, a handling mechanism 400, a silicon steel sheet storage rack 500, a temporary storage and transfer mechanism 600, an inspection mechanism 700, and a loading platform 800.

[0025] The truss main body 100 has a portal frame structure, which has good rigidity and stability and can avoid the impact of vibration on positioning accuracy during operation. Racks 110 are symmetrically fixed on both sides of its top along the X-axis, providing a basis for the precise movement of the drive component 200.

[0026] The drive assembly 200 includes a support frame 210, a rotating shaft 220, a first gear 230, and a drive mechanism 240. The bottom of the support frame 210 slides with the guide rail of the truss body 100 via a slider to achieve guided movement along the X-axis. The rotating shaft 220 is installed in the bearing seats on both sides of the support frame 210 via deep groove ball bearings. The two ends of the rotating shaft 220 are fixedly connected to the first gear 230 via flat keys. The first gear 230 meshes with the rack 110 of the truss body 100. The output shaft of the drive mechanism 240 is connected to the rotating shaft 220 via a coupling, which can drive the rotating shaft 220 to drive the first gear 230 to rotate, thereby achieving uniform and precise movement of the support frame 210 along the X-axis.

[0027] The stacking mechanism 300 includes a first Y and Z dual-axis moving assembly 310, a horizontal rotating seat 320, a first guide sliding seat 330, a first sliding plate 340, a first lead screw assembly 350, a first gripper 360, and a material detection component. The first Y and Z dual-axis moving assembly 310 adopts a ball screw slide module, which has a horizontal rotation drive motor 310a embedded inside, and the output end is fixed with a second gear 310b through a flat key.

[0028] The horizontal rotating seat 320 has a disc-shaped structure. The top of the seat is rotatably connected to the bottom bearing seat of the first Y and Z dual-axis moving assembly 310 via a drive shaft. A third gear 320a is fixed on the drive shaft. The third gear 320b meshes with the second gear 310b, which enables the horizontal rotating seat 320 to rotate.

[0029] The first guide slide seat 330 is symmetrically fixed at the bottom of the horizontal rotating seat 320. It has a linear guide rail inside. The first slide plate 340 slides with the linear guide rail through a slider. The first lead screw assembly 350 passes through the two first slide plates 340. The two ends of the lead screw are installed on the first guide slide seat 330 through bearing seats. One end of the lead screw is connected to a servo motor. The motor drives the two first slide plates 340 to move closer or further away synchronously through forward and reverse rotation. It is suitable for silicon steel sheets of different sizes.

[0030] The first gripper 360 is fixed to both ends of the first slide plate 340 and includes a support column 360a, a hook 360b, and a gripper cylinder 360c. The support column 360a is vertically fixed to the first slide plate 340. The middle part of the hook 360b is hinged to the support column 360a through a pin. The gripping end of the hook 360b is provided with a rubber anti-slip pad to avoid damaging the surface of the silicon steel sheet. The two ends of the gripper cylinder 360c are respectively hinged to the end of the hook 360b and the first slide plate 340 through fisheye connectors. When the cylinder retracts, it drives the hook 360b to clamp. When it extends, it drives the hook 360b to open. The material detection component adopts a diffuse reflection photoelectric sensor, which is fixed to the inner side of the first gripper 360. It can detect in real time whether the hook 360b is gripping the silicon steel sheet. When no material is detected, a supplementary gripping signal is triggered.

[0031] The conveying mechanism 400 includes a second Y and Z dual-axis moving assembly 410, a conveying base 420, a second guide sliding seat 430, a second sliding plate 440, a second lead screw assembly 450, and a second gripper 460. Its structure is consistent with the moving and adjusting principle of the stacking mechanism 300. The difference is that the end of the second gripper 460 is provided with a hook block 460a. The hook block 460a has an L-shaped structure and a stepped surface on its inner side, which can support and clamp the silicon steel sheet assembly from the bottom to prevent the silicon steel sheet assembly from falling off during the transfer process.

[0032] The silicon steel sheet storage rack 500 has a frame structure with a material placement platform on top. Three positioning cylinders 510 are evenly arranged around it. When the three positioning cylinders 510 extend synchronously, they limit and correct the silicon steel sheet from the outer periphery to ensure the positioning accuracy of the stacking mechanism 300 when it grabs the sheet.

[0033] The temporary storage and transfer mechanism 600 includes a transfer seat 610, guide columns 620, a bearing seat 630, and a third lead screw assembly 640. The transfer seat 610 is fixed to the ground foundation, and four guide columns 620 are symmetrically fixed to the top. The guide columns 620 are equipped with guide rods 620a and protrusions 620b. The protrusions 620b are distributed circumferentially along the guide columns 620 to form a limiting structure for stacking silicon steel sheets, ensuring coaxiality during stacking. The bearing seat 630 is sleeved on the guide rods 620a and slides with the guide rods 620a through a linear bearing. The top surface of the bearing seat 630 is flush with the top surface of the protrusions 620b, and is used to support the silicon steel sheets during the stacking process. The third lead screw assembly 640 is installed at the bottom of the transfer seat 610, and its lead screw top is connected to the bearing seat 630, which can drive the bearing seat 630 to rise and fall along the guide rods 620a. After stacking, the silicon steel sheet group is lifted to the transfer height.

[0034] The inspection unit 700 is equipped with a weighing unit, which is electrically connected to the equipment control system. It can transmit the measured weight to the controller in real time and compare it with the product of the weight of a single silicon steel sheet and the number of target stacked sheets. If the difference is within ±0.5%, it is considered qualified.

[0035] The unloading platform 800 is a steel structure platform, and its height is level with the weighing platform of the inspection mechanism 700, which facilitates the transfer of silicon steel sheet groups by the handling mechanism 400. A qualified product conveyor roller is provided on one side of the platform, which can automatically transport the unloaded silicon steel sheet groups to the subsequent processes.

[0036] Combination Figures 1-7 The conveying mechanism of the truss rotor silicon steel sheet stacking and loading / unloading device according to this embodiment has the following specific steps: After the equipment is started, the control system issues a reset command. The servo motor of the drive component 200 drives the support frame 210 back to the X-axis mechanical origin. The first Y and Z dual-axis moving component 310 of the stacking mechanism 300 drives the horizontal rotating seat 320 back to the Y and Z axis origins. The gripper hook 360b is in the open state under the action of the gripper cylinder 360c extending. The conveying mechanism 400 returns to the origin of each axis simultaneously. The second gripper 460 opens. The carrier seat 630 of the temporary storage and transfer mechanism 600 is driven to descend to the lowest position by the third lead screw component 640. The inspection mechanism 700 is zeroed and calibrated. The operator sets the target stacking quantity, silicon steel sheet size parameters and single silicon steel sheet weight through the touch screen. Silicon steel sheets are fed into the placement platform of the silicon steel sheet storage rack 500 by manual operation or by the preceding conveyor line. After the control system detects the material, it controls three positioning cylinders 510 to extend synchronously. The positioning blocks limit and correct the silicon steel sheet from the outer periphery to ensure that the center of the silicon steel sheet is aligned with the gripping center of the stacking mechanism 300. Then the positioning cylinders 510 retract.

[0037] The servo motor of the drive component 200 is started, which drives the support frame 210 to move along the X-axis to above the silicon steel sheet storage rack 500. The first Y-axis moving component of the stacking mechanism 300 drives the horizontal rotating seat 320 to move directly above the silicon steel sheet, and the Z-axis moving component drives the first gripper 360 to descend to the gripping height. After the material detection component detects the silicon steel sheet, the servo motor of the first lead screw assembly 350 starts, driving the two first slide plates 340 to move closer to each other, adjusting the spacing of the grippers 360b to match the size of the silicon steel sheet. Then, the gripper cylinder 360c retracts, driving the grippers 360b to clamp the silicon steel sheet. After the material detection component confirms that the gripping is in place for the second time, the Z-axis moving assembly drives the first gripper 360 to rise to avoid interference with the storage rack. Afterward, the first Y-axis moving assembly drives the horizontal rotating seat 320 to move. If it is necessary to adjust the stacking angle, the horizontal rotation drive motor 310a starts, and through the meshing of the second gear 310b and the third gear 320a, it drives the horizontal rotating seat 320 to rotate to the preset angle. Then, the Z-axis moving assembly drives the first gripper 360 to descend, accurately placing the silicon steel sheet within the limiting structure formed by the guide post 620 and the protrusion 620b of the temporary storage and transfer mechanism 600. The gripper cylinder 360c extends and opens the grippers 360b, completing the stacking of a single silicon steel sheet. Repeat the grabbing, transporting, and placing actions described above until the target number of stacks is reached.

[0038] After the stacking is completed, the third lead screw assembly 640 of the temporary storage and transfer mechanism 600 starts the drive motor, which drives the bearing seat 630 to slide upward along the guide rod 620a, lifting the silicon steel sheet assembly to a height of 100mm. Then the third lead screw assembly 640 stops moving and locks.

[0039] The drive assembly 200 moves the support frame 210 along the X-axis to above the temporary storage and transfer mechanism 600. The second Y-axis moving assembly of the conveying mechanism 400 moves the conveying base 420 to directly below the silicon steel sheet group. The Z-axis moving assembly moves the second gripper 460 down to both sides of the bottom of the silicon steel sheet group. The second lead screw assembly 450 moves the two second slide plates 440 closer to each other. After the hook block 460a of the second gripper 460 supports and clamps the silicon steel sheet group from the bottom, the Z-axis moving assembly moves the second gripper 460 up. The second Y-axis moving assembly moves the conveying base 420. The drive assembly 200 moves the support frame 210 along the X-axis to above the inspection mechanism 700. The Z-axis moving assembly moves the second gripper 460 down, placing the silicon steel sheet group in the positioning slot of the inspection mechanism 700. The second gripper 460 then releases. The weighing unit of the inspection agency 700 measures the total weight of the silicon steel sheet assembly. If the measured weight is 5.0kg ± 0.025kg, it is deemed qualified, and the controller receives a qualified signal; if the weight exceeds this range, it is deemed unqualified, and the controller triggers an audible and visual alarm.

[0040] If the verification is successful, the second gripper 460 of the conveying mechanism 400 clamps the silicon steel sheet group again. Through the coordinated action of the Z-axis, Y-axis, and X-axis moving components, the silicon steel sheet group is transferred to the unloading platform 800. The second gripper 460 then releases, and the silicon steel sheet group falls into the conveyor roller of the unloading platform for transport to the subsequent process. If the verification is unsuccessful, the equipment stops running. After the operator investigates and resolves the discrepancy in the number of sheets, the equipment is restarted. After all operations are completed, the drive component 200, the stacking mechanism 300, the conveying mechanism 400, and the temporary storage and transfer mechanism 600 automatically reset to their initial positions and enter the next cycle of operation.

[0041] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.

9. The truss rotor silicon steel sheet stacking and loading / unloading device according to claim 1, characterized in that, The inspection agency (700) is equipped with a weighing unit to verify the actual number of silicon steel sheets stacked by measuring weight and to provide feedback on the verification results.

10. A method for operating a truss rotor silicon steel sheet stacking and loading / unloading device as described in any one of claims 1-9, characterized in that, The steps are as follows: S1. After the equipment is initialized, the silicon steel sheet is fed into the silicon steel sheet storage rack (500) equipped with a positioning cylinder (510). The positioning cylinder (510) extends to correct the position of the silicon steel sheet and retracts after correction. S2. The drive assembly (200) drives the stacking mechanism (300) to move to the silicon steel sheet storage rack (500). After the material detection component of the stacking mechanism (300) confirms the position of the silicon steel sheet, its first lead screw assembly (350) drives the first slide plate (340) to adjust the spacing. The gripper cylinder (360c) drives the gripper hook (360b) to clamp the silicon steel sheet. Through the coordinated action of the first Y and Z dual-axis moving assembly (310) and the horizontal rotating seat (320), the silicon steel sheet is transferred to the guide column (620) and the protrusion (620b) of the temporary storage transfer mechanism (600) for precise placement. The gripping, transfer and placement actions are repeated until the target number of stacked sheets is completed. S3. The third screw assembly (640) of the temporary storage and transfer mechanism (600) drives the bearing seat (630) to slide upward along the guide rod (620a) to lift the silicon steel sheet group to a preset height; the drive assembly (200) drives the handling mechanism (400) to move below the temporary storage and transfer mechanism (600), and its second screw assembly (450) drives the second slide plate (440) to approach, and the hook block (460a) of the second gripper (460) clamps the silicon steel sheet group from the bottom, and transfers it to the inspection mechanism (700) equipped with a weighing unit through the second Y and Z dual-axis moving assembly (410). The inspection mechanism (700) verifies the number of stacked sheets by weight measurement and feeds back the result. If the verification is qualified, the handling mechanism (400) transfers the silicon steel sheet group to the unloading platform (800) and releases it to complete the unloading. If it is unqualified, an abnormal prompt is triggered. S4. After all operations are completed, the drive component (200), stacking mechanism (300), conveying mechanism (400) and temporary storage transfer mechanism (600) are reset to their initial positions and enter the next cycle to realize automatic loading and unloading and precise stacking of silicon steel sheets.
