Description

Technical Field

[0001] This application relates to the field of motor core stamping technology, and in particular to an automatic feeding and screening mechanism for motor core stamping. Background Technology

[0002] In the stator winding of an electric motor, a magnetic field is generated when current passes through the winding. The motor core, as the medium for conducting the magnetic field, can concentrate the magnetic field generated by the winding and conduct it according to the designed path. The precisely designed stamping die completes the stamping operation according to the shape and size of the motor core. It is made of high-strength steel, which meets the needs of large-scale and high-frequency stamping and ensures the accuracy and consistency of the core laminations.

[0003] However, existing technologies still have the following problems:

[0004] Existing automatic feeding and screening mechanisms for stamping motor cores are mostly low in automation and inconvenient to adjust. If the qualified products are distinguished from the defective products by visual observation and manual sorting, the entire production process will be inefficient. As the production time increases, workers will also easily become fatigued. Furthermore, the fixed mechanical structure of traditional mechanisms cannot quickly adapt to product changes, resulting in a lot of time and manpower being spent on readjustment and calibration when the equipment is changed.

[0005] In response to the aforementioned technologies, the inventors propose an automatic feeding and screening mechanism for stamping motor iron cores to solve the above problems. Utility Model Content

[0006] The purpose of this application is to provide an automatic feeding and screening mechanism for stamping motor iron cores, so as to improve the problems of low automation and inconvenience in adjustment of the automatic feeding and screening mechanism for stamping motor iron cores.

[0007] The automatic feeding and screening mechanism for stamping motor iron cores provided in this application adopts the following technical solution:

[0008] An automatic feeding and screening mechanism for stamping motor iron cores includes a base support. An electric push rod is fixedly mounted on the upper surface of the base support, and a support plate is fixedly mounted on the upper end of the electric push rod. A carrier plate is mounted above the support plate, and a transmission assembly is fixedly mounted on the upper surface of the carrier plate. A qualified box and a defective box are located below one side of the transmission assembly. A drive box is fixedly mounted on the lower surface of the support plate, and a drive gear and a driven gear are rotatably mounted inside the drive box. The drive gear and the driven gear are meshed and connected. A DC motor is fixedly mounted on one side of the lower surface of the drive box, and the output end of the DC motor passes through the drive box and is fixedly connected to the drive gear. A support column is fixedly mounted on the upper surface of the driven gear, and an indirect plate is fixedly mounted on the upper end of the support column through the support plate. The indirect plate is detachably connected to the carrier plate.

[0009] By adopting the above technical solution, the electric push rod can accurately control the height of the carrier plate to adapt to the needs of different production stages. The DC motor rotates the carrier plate through gear transmission, which facilitates the handling of defective products.

[0010] Optionally, an adjustment frame is provided above the transmission assembly, and a lead screw is rotatably provided inside the adjustment frame. A servo motor is fixedly provided on the upper surface of the adjustment frame, and the output end of the servo motor passes through the adjustment frame and is fixedly connected to the lead screw. A lifting block is threaded onto the outer surface of the lead screw, and a baffle is fixedly provided on one side of the lifting block.

[0011] By adopting the above technical solution, the servo motor drives the lead screw to rotate, which in turn drives the baffle to rise and fall, thereby flexibly adjusting the screening height of the motor core and achieving precise screening.

[0012] Optionally, a limiting groove is provided on the upper surface of the support plate, and a limiting member is fixedly provided on one side of the indirect plate, and the limiting member is engaged in the limiting groove.

[0013] By adopting the above technical solution, the limiting groove and the limiting component work together to effectively constrain the rotation range of the indirect plate, ensuring the stability and accuracy of the plate rotation.

[0014] Optionally, the upper surface of the indirect plate is symmetrically fixed with mounting plates, the carrier plate is clamped on the mounting plates, and the mounting plates and the carrier plates are connected by bolts.

[0015] By adopting the above technical solution, the mounting plate and bolt connection make the installation and disassembly of the carrier plate convenient, which is conducive to equipment maintenance and component replacement.

[0016] Optionally, a base plate is provided on one side of the base support, and the qualified box and the defective box are placed on the base plate. An inclined guide plate is fixedly provided on one side of the upper surface of the base plate.

[0017] By adopting the above technical solution, the base plate provides a stable placement platform for qualified boxes and defective boxes, and the inclined guide plate guides the qualified iron cores to fall smoothly into the boxes.

[0018] Optionally, both the qualified product box and the defective product box are equipped with protective padding.

[0019] By adopting the above technical solution, the protective pad can buffer the impact of the iron core falling into the box, avoid damage to the iron core, and ensure product quality.

[0020] Optionally, a reinforcing frame is fixedly provided on one side of the adjustment frame, and the reinforcing frame is fixedly connected to the transmission assembly.

[0021] By adopting the above technical solution, the reinforcement frame enhances the connection strength between the adjustment frame and the transmission components, thereby improving the overall structural stability.

[0022] Optionally, the upper surface of the transmission assembly is symmetrically fixed with positioning posts, and the baffle is movably sleeved on the outer surface of the positioning posts.

[0023] By adopting the above technical solution, the positioning column provides guidance for the lifting and lowering of the baffle, ensuring smooth movement of the baffle and precise control of the iron core screening.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. This application utilizes the coordinated operation of electric push rods, DC motors, servo motors, etc., to automate the entire material feeding and screening process without extensive manual intervention. This achieves an automated process from core conveying and testing to classified collection, improving production efficiency and reducing labor costs and potential errors caused by manual operation. Furthermore, by precisely controlling the height of the baffles with servo motors, accurate screening can be performed based on the specific dimensions or quality standards of the cores, ensuring the effective separation of qualified and defective products and improving the stability and consistency of product quality.

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail below. Example

[0032] An automatic feeding and screening mechanism for stamping motor iron cores, as described in the following figure. Figure 1-4The system includes a base support 1, on the upper surface of which an electric push rod 11 is fixedly mounted. The electric push rod 11 is selected based on a model with sufficient thrust and stability to adapt to different load requirements. Its installation position is precisely designed and adjusted to ensure the accuracy of subsequent actions. A support plate 2 is fixedly mounted on the upper end of the electric push rod 11, and a carrier plate 3 is mounted above the support plate 2. A transmission assembly 31 is fixedly mounted on the upper surface of the carrier plate 3. The transmission assembly 31 adopts a roller structure with a certain degree of friction and wear resistance, enabling smooth transport of the motor core. Its transmission speed can be adjusted according to the production rhythm to ensure matching with the output speed of the stamping process. The bottom side is equipped with a qualified box 42 and a defective box 43. A base plate 4 is provided on one side of the base support 1. The qualified box 42 and the defective box 43 are placed on the base plate 4. An inclined guide plate 41 is fixed on one side of the upper surface of the base plate 4. Protective pads 44 are fixedly provided inside the qualified box 42 and the defective box 43. The electric push rod 11 can control the lifting and lowering of the support plate 2, thereby driving the carrier plate 3 and the transmission assembly 31 above it to rise or fall as a whole. The stamped motor core is placed on the transmission assembly 31. The transmission assembly 31 can transport the core forward. The protective pads 44 inside the qualified box 42 and the defective box 43 can prevent the core from being damaged by collision when it falls into the box, thus protecting the appearance and quality of the product.

[0033] Reference Figure 3 A drive box 21 is fixedly installed on the lower surface of the support plate 2, and a drive gear 22 and a driven gear 23 are rotatably installed inside the drive box 21. The drive gear 22 and the driven gear 23 are meshed and connected. A DC motor 24 is fixedly installed on one side of the lower surface of the drive box 21, and the output end of the DC motor 24 passes through the drive box 21 and is fixedly connected to the drive gear 22. A support column 29 is fixedly installed on the upper surface of the driven gear 23. The upper end of the support column 29 passes through the support plate 2 and is fixedly installed with an indirect plate 25. The indirect plate 25 is detachably connected to the carrier plate 3. A limit groove 27 is opened on the upper surface of the support plate 2. A limit member 28 is fixedly installed on one side of the indirect plate 25 and is locked in the limit groove 27. When the DC motor 24 is working, its output end drives the drive gear 22 to rotate. Since the drive gear 22 meshes with the driven gear 23, the driven gear 23 rotates accordingly. The support column 29 on the driven gear 23 drives the indirect plate 25 to rotate. The indirect plate 25 is connected to the carrier plate 3, thereby realizing the rotation of the carrier plate 3. The limiting member 28 can only move within the limiting groove 27, which can better facilitate the entry of the defective product into the defective product box 43.

[0034] Reference Figure 3 Mounting plates 26 are symmetrically fixed on the upper surface of the indirect plate 25. The carrier plate 3 is clamped on the mounting plate 26, and the mounting plate 26 and the carrier plate 3 are connected by bolts. The carrier plate 3 and the indirect plate 25 are connected by the mounting plate 26 and bolts, which facilitates the installation, maintenance and replacement of the carrier plate 3.

[0035] Reference Figure 2 An adjusting frame 32 is provided above the transmission component 31. A reinforcing frame 37 is fixedly provided on one side of the adjusting frame 32 and is fixedly connected to the transmission component 31. A lead screw 33 is rotatably provided inside the adjusting frame 32. A servo motor 34 is fixedly provided on the upper surface of the adjusting frame 32, and the output end of the servo motor 34 passes through the adjusting frame 32 and is fixedly connected to the lead screw 33. A lifting block 35 is threaded onto the outer surface of the lead screw 33, and a baffle 36 is fixedly provided on one side of the lifting block 35. Positioning posts 38 are symmetrically fixed on the upper surface of the transmission component 31. The baffle 36 is movably sleeved on the outer surface of the positioning posts 38. The positioning posts 38 provide a stable guiding effect for the lifting of the baffle 36, ensuring that the baffle 36 moves up and down. During the movement, the system remains vertical and stable to avoid tilting or jamming, ensuring accurate interception and release of the motor core. When the core reaches the designated position, the servo motor 34 starts, driving the lead screw 33 to rotate. The lifting block 35 on the lead screw 33 moves up and down along the lead screw, and the baffle 36 on one side of the lifting block 35 moves accordingly. Through cooperation with the positioning column 38, the baffle 36 can adjust its height, thereby blocking or releasing cores of different sizes or states. Qualified cores continue to move forward under the action of the transmission component 31 and slide into the qualified box 42 through the inclined guide plate 41. Unqualified cores are intercepted by the baffle 36 and poured into the defective box 43 as the carrier plate 3 rotates.

[0036] The implementation principle of this application embodiment is as follows: the electric push rod 11 can control the lifting and lowering of the support plate 2, thereby driving the carrier plate 3 and the transmission assembly 31 above it to rise or fall as a whole. The stamped motor core is placed on the transmission assembly 31, and the transmission assembly 31 can transport the core forward. The protective pads 44 in the qualified box 42 and the defective box 43 can prevent the core from being damaged by collision when it falls into the box, thus protecting the appearance and quality of the product.

[0037] When the DC motor 24 is working, its output end drives the drive gear 22 to rotate. Since the drive gear 22 meshes with the driven gear 23, the driven gear 23 rotates accordingly. The support column 29 on the driven gear 23 drives the indirect plate 25 to rotate. The indirect plate 25 is connected to the carrier plate 3, thereby realizing the rotation of the carrier plate 3. The limiting member 28 can only move within the limiting groove 27, which can better facilitate the entry of the defective product into the defective product box 43.

[0038] The carrier plate 3 and the indirect plate 25 are connected by the mounting plate 26 and bolts, which facilitates the installation, maintenance and replacement of the carrier plate 3.

[0039] When the iron core reaches the designated position, the servo motor 34 starts, driving the lead screw 33 to rotate. The lifting block 35 on the lead screw 33 moves up and down along the lead screw, and the baffle 36 on one side of the lifting block 35 moves accordingly. Through cooperation with the positioning column 38, the baffle 36 can adjust its height, thereby blocking or allowing iron cores of different sizes or states. Qualified iron cores continue to move forward under the action of the transmission component 31 and slide into the qualified box 42 through the inclined guide plate 41. Qualified iron cores are intercepted by the baffle 36 and, with the rotation of the carrier plate 3, are poured into the defective box 43.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
