Description

Technical Field

[0001] This utility model relates to the field of motor production equipment technology, specifically to a rapid stamping and sorting equipment for motor stator laminations. Background Technology

[0002] As a core component of a motor, the manufacturing quality of motor stator laminations directly affects the motor's energy efficiency, noise, and operational reliability. Currently, motor stator laminations are typically produced in batches from silicon steel sheets using stamping equipment. During the stamping process, due to factors such as die wear, gap changes, or material fluctuations, burrs, micro-cracks, or dimensional deviations inevitably occur on the edges of the laminations. If these defective products flow into subsequent lamination, winding, and assembly processes, it will lead to a decline in motor product performance or even scrapping.

[0003] Referring to the patent document: Patent Publication No. CN219503264U, Patent Publication Date 2023-08-11, an automatic sorting device for motor laminations is disclosed, including a fixed frame. A conveying mechanism for conveying laminations is provided on the fixed frame. An identification mechanism for detecting and identifying stators, rotors, and waste wafers is provided on one side of the fixed frame above the conveying mechanism. A sorting mechanism for sorting laminations is provided on the other side of the fixed frame. A control box for controlling the conveying mechanism, identification mechanism, and sorting mechanism is provided on the fixed frame. The identification mechanism includes detection sensor A, detection sensor B, and detection sensor C, which are sequentially arranged on the fixed frame at the upper end of the conveying mechanism. The entire process can achieve unmanned management, has low maintenance costs, and can quickly judge and sort laminations after detection, greatly improving the production efficiency of laminations.

[0004] Based on the search of patent numbers and the shortcomings of existing technologies, the following was found: Currently, the production process of motor stator laminations mainly includes two stages: stamping and forming, and appearance inspection and sorting. However, the sorting of motor stator laminations typically employs manual or automated inspection via machine vision. Manual inspection involves operators visually inspecting each lamination or using simple measuring tools, manually removing defective products. This method is not only labor-intensive and inefficient, but also susceptible to subjective factors and fatigue, making it difficult to standardize inspection criteria and prone to missed inspections and misjudgments. While some production lines use automated machine vision inspection equipment to inspect the stamped laminations, this typically involves conveying the laminations via a conveyor belt while the inspection equipment is positioned above. This results in image acquisition only from a single surface (usually the top surface). Since the other side of the lamination is facing down during transport, it cannot be inspected, creating a "blind spot" where defects on the back side cannot be identified, and quality risks remain.

[0005] Therefore, this utility model provides a rapid stamping and sorting device for motor stator laminations. Utility Model Content

[0006] To address the issues of low efficiency, inconsistent standards, or blind spots in the inspection and sorting of motor stator laminations, whether relying on manual visual inspection or partially automated equipment, the present invention aims to provide a rapid stamping and sorting device for motor stator laminations.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rapid stamping and sorting device for motor stator laminations, comprising a base, a stamping device fixedly mounted on one side of the top of the base, and a sorting mechanism on one side of the stamping device for visual inspection of the stamped motor stators. The sorting mechanism includes: The flipping assembly includes a fixed frame that is fixedly installed on the other side of the top of the base. A conveyor belt is provided on the side of the fixed frame near the stamping equipment. Two industrial inspection cameras that cooperate with each other are fixedly installed on the top of the fixed frame. A rotating shaft is rotatably installed on the upper side of the fixed frame. Two symmetrically distributed flipping discs are fixedly installed on the upper part of the rotating shaft. A mounting frame is fixedly installed on the lower side of the fixed frame. A rotating disc is rotatably installed on the upper side of the mounting frame. A drive block is fixedly installed on one side of the rotating disc. A rotating frame is fixedly installed at one end of the rotating shaft. Multiple drive slots that cooperate with the drive block are opened in the middle of the rotating frame. The screening component, located on the upper side of the fixed frame, is used to distinguish the motor stators to be tested.

[0008] Preferably, the screening assembly includes a rotating frame rotatably mounted on one side of the upper part of the fixed frame, a set of electromagnets fixedly mounted on the lower parts of both sides of the rotating frame, a support frame fixedly mounted on one side of the lower part of the fixed frame, a rotating cylinder fixedly mounted on one side of the top of the support frame, the driving end of the rotating cylinder fixedly mounted in the middle of the rotating frame, and a second conveyor belt provided on one side of the upper part of the fixed frame.

[0009] Preferably, the drive assembly includes a drive motor fixedly mounted on one side of the top of the mounting bracket, and a rotating disk fixedly mounted on the drive end of the drive motor at the middle of one side.

[0010] Preferably, a limiting block is fixedly installed in the middle of one side of the rotating disk, and multiple limiting grooves are provided on the outer side of the rotating frame for mutual cooperation.

[0011] Preferably, the two flip disks have multiple slots arranged in a ring array in the middle, which are used to lock and fix the motor stator.

[0012] Preferably, a collection box is provided at the top center of the support frame, and the collection box is used to load defective motor stators.

[0013] Beneficial effects This invention provides a rapid punching and sorting device for motor stator laminations. Compared with the prior art, it has the following advantages: 1. After the stamping sheet is fed into the tilting disc slot by the No. 1 conveyor belt, the drive motor drives the rotating disc, so that the drive block cooperates with the drive slot of the rotating frame, causing the rotating shaft and the tilting disc to rotate intermittently. The limit block and the limit slot ensure stable rotation. The stamping sheet completes a 180-degree rotation with the tilting disc. During the process, the industrial inspection camera first inspects the upper surface of the stamping sheet during the conveying process, and then collects images again after the rotation. This can comprehensively identify defects such as burrs and cracks, avoid omissions in single-sided inspection, and provide a reliable basis for subsequent sorting.

[0014] 2. After testing, the blanks are conveyed by the second conveyor belt. The control system instructs the screening component according to the test results. When the defective products enter the workstation, the rotary cylinder drives the rotating frame and electromagnet to rotate 180 degrees. The corresponding electromagnet is energized to attract the defective products. After rotating back to the top of the collection box, the power is cut off to release them. The magnetism of the electromagnet can be adjusted by the current to ensure stable attraction and easy picking and putting. The inner wall of the collection box is buffered with sponge to prevent the defective products from being damaged by collision when they fall in. The sorting is fast and avoids the error of manual sorting, thereby improving the overall production efficiency. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a rapid stamping and sorting device for motor stator laminations, including a base 1. A stamping device 11 is fixedly installed on one side of the top of the base 1. The stamping device 11 is equipped with a high-precision servo drive system and an automatic feeding mechanism, which can realize continuous and precise stamping of motor stator laminations. A sorting mechanism 2 is provided on one side of the stamping device 11 for visual inspection of the stamped motor stators, such as burrs, cracks, dimensional deviations, etc., and for classifying qualified and defective products. The sorting mechanism 2 includes: The flipping assembly 21 includes a fixed frame 211 fixedly installed on the other side of the top of the base 1. A first conveyor belt 218 is provided on the side of the fixed frame 211 closest to the stamping equipment 11. Both the first conveyor belt 218 and the second conveyor belt 221 are driven by a servo motor. Two industrial inspection cameras 219 are fixedly installed on the top of the fixed frame 211, working in conjunction with each other. Each industrial inspection camera 219 consists of two cameras, symmetrically distributed, which acquire images from two sides of the motor stator lamination. It can complete the identification of appearance defects in a single lamination within 0.5 seconds, with an accuracy rate exceeding 99.5%. A rotating shaft 216 is rotatably mounted on the upper side of the fixed frame 211. The rotating shaft 216 is connected to the fixed frame 211 via a deep groove ball bearing. The fixed frames 211 are interconnected. Two symmetrically distributed rotating disks 217 are fixedly installed on the upper part of the rotating shaft 216. A mounting frame 2111 is fixedly installed on one side of the lower part of the fixed frame 211. The mounting frame 2111 has an L-shaped structure and is installed on the lower side of the fixed frame 211 by bolts. A rotating disk 2121 is rotatably installed on the upper side of the mounting frame 2111. A drive block 213 is fixedly installed on one side of the rotating disk 2121. A rotating frame 215 is fixedly installed at one end of the rotating shaft 216. The middle part of the rotating frame 215 has multiple drive slots 2131 that cooperate with the drive block 213. When the drive block 213 is embedded in the drive slot 2131, it can drive the rotating frame 215 to rotate intermittently around the rotating shaft 216. The screening component 22 is located on the upper side of the fixed frame 211 and is used to distinguish the motor stators to be tested.

[0023] The screening assembly 22 includes a rotating frame 225 rotatably mounted on one side of the upper part of the fixed frame 211. A set of electromagnets 226 is fixedly mounted on the lower parts of both sides of the rotating frame 225. Each set of electromagnets 226 has four electromagnets, and the adsorption surface of the electromagnets 226 is in contact with the surface of the motor stator laminations. The magnetic strength of the electromagnets 226 can be adjusted by current to ensure stable adsorption of the laminations and to prevent difficulty in picking up or putting down due to excessive magnetism. A support frame 222 is fixedly mounted on one side of the lower part of the fixed frame 211. A rotary cylinder 224 is fixedly installed on one side of the top of the 22. The rotary cylinder 224 is fixed to the upper part of the support frame 222 by a flange. The rotary cylinder 224 is an MSQB63 rotary cylinder. It can be rotated 180° by the rotating frame 225 to attract and transfer the defective products by the electromagnet 226 and put them into the collection box 223. The middle part of the rotating frame 225 is fixedly installed on the drive end of the rotary cylinder 224. A second conveyor belt 221 is provided on one side of the upper part of the fixed frame 211.

[0024] The drive assembly includes a drive motor 212 fixedly mounted on one side of the top of the mounting bracket 2111, and a drive end of the drive motor 212 fixedly mounted on one side of the rotating disk 2121. The drive motor 212 can be of model IM35ET020, which can drive the rotating disk 2121 to rotate.

[0025] A limiting block 214 is fixedly installed in the middle of one side of the rotating disk 2121. Multiple limiting grooves 2141 are opened on the outer side of the rotating frame 215 to cooperate with it. When the rotating disk 2121 rotates, the rotating frame 215 can be driven to rotate by the cooperation of the driving block 213 and the driving groove 2131. When the driving block 213 disengages from the driving groove 2131, its limiting block 214 will immediately be inserted into the limiting groove 2141, thereby preventing the rotating frame 215 from rotating and thus achieving an intermittent rotation effect.

[0026] Multiple circular array slots 2171 are provided in the middle of the two rotating discs 217. The slots 2171 are used to lock and fix the motor stator. The number of slots 2171 is the same as that of the drive slots 2131 and the limiting slots 2141. The inner wall of the slots 2171 is provided with elastic rubber pads. The shape of the pads matches the outer contour of the motor stator laminations. The pads are used to lock and fix the motor stator laminations and prevent the laminations from shifting during the rotation. At the same time, the elastic rubber pads can prevent the lamination surface from being scratched. When the motor stator is fed into the slots 2171 by the first conveyor belt 218, the motor stator is rotated by the intermittent rotation of the rotating discs 217. The second conveyor belt 221 is fed into the upper side, and the rotation of the second conveyor belt 221 is used to transport and detect the stator.

[0027] A collection box 223 is provided at the top center of the support frame 222. The collection box 223 is used to load defective motor stators. It is made of plastic and its inner wall is provided with a buffer sponge layer to prevent secondary damage caused by collision when the defective stampings fall in.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] During operation, the silicon steel coil is first precisely and continuously fed into a high-precision mold via an automatic feeding mechanism integrated into the stamping equipment 11. Under the control of a servo drive system, the stamping equipment 11 performs high-speed punching to produce individual motor stator laminations. The stamped stator laminations are then sent out and received by the first conveyor belt 218, and transported toward the sorting mechanism 2. Under the transport of the first conveyor belt 218, the upper surface of the motor stator is first inspected by an industrial inspection camera 219 located above the first conveyor belt 218. After inspection, the lamination is accurately fed into the slot 2171 on the rotating disc 217. The drive motor 212 starts, causing the rotating disc 2121 to rotate. The drive block 213 moves accordingly and periodically engages with the drive mechanism of the rotating frame 215. In the groove 2131, the rotating frame 215 and the rotating shaft 216 are driven to rotate intermittently. During this process, the cooperation between the limiting block 214 and the limiting groove 2141 ensures the stability of the rotating frame 215 in the non-drive stage and realizes precise intermittent movement. Finally, the two rotating discs 217 rotate intermittently in sync and complete a 180-degree rotation during the movement, so that they reach the upper part of the second conveyor belt 221. Under its rotation, the rotated motor stator is conveyed. When the stator lamination passes the two industrial inspection cameras 219 at the top of the fixed frame 211 with the rotating disc 217, the cameras are triggered again to perform high-speed image acquisition and identify defects such as burrs, cracks, and dimensional deviations. The acquired image data is transmitted to the control system for real-time analysis and processing. The stator laminations that have passed inspection are sent to the second conveyor belt 221. At the same time, the control system generates a sorting instruction based on the visual inspection results. The second conveyor belt 221 operates normally, transporting the qualified stator laminations to the next process (such as stacking or packaging units). For defective products: when a defective product enters the sorting station, the rotary cylinder 224 immediately activates, driving the rotating frame 225 and the electromagnets 226 on both sides to rotate 180 degrees. At this time, a set of electromagnets 226 facing the second conveyor belt 221 is energized, generating a precisely controlled magnetic force to stably attract the defective laminations. Subsequently, the rotary cylinder 224 activates again, turning the rotating frame 225 back, moving the defective laminations above the collection box 223. At this time, the set of electromagnets 226 is de-energized, releasing the defective laminations so that they fall into the collection box 223 with buffer sponge on the inner wall to avoid secondary damage. Meanwhile, the other set of electromagnets 226 is ready for the next attraction operation.
