Description

Technical Field

[0001] This application relates to the field of stamping forming apparatus for stator machining, and in particular to a stamping forming apparatus for stator machining. Background Technology

[0002] In the manufacturing process of the stator, a core component of an electric motor, stamping is a crucial step that determines the precision and performance of the stator product. Its processing efficiency and quality directly impact the overall production progress and performance stability of the motor. Currently, traditional stator stamping equipment in the industry still suffers from significant automation shortcomings in this core processing stage, with a prominent reliance on manual intervention. During the billet loading stage, stator billets must be manually placed one by one to the designated positions. This is not only cumbersome and time-consuming, limiting single-shift capacity, but also prone to positional deviations, directly causing dimensional errors in subsequent stamping processes and increasing the risk of scrap. In the billet positioning and stamping connection stage, traditional equipment lacks an efficient billet transfer and positioning coordination structure, often requiring manual assistance to align the keyways, positioning holes, and other features of the billet. This not only results in poor positioning consistency, affecting the compatibility of subsequent stator assembly, but also frequently interrupts the stamping rhythm, further reducing production efficiency. In the finished product collection and transfer stage, manual handling of stator sheets can easily cause scratches on the surface of the sheets due to contact friction, affecting the product's appearance and performance. At the same time, the intermittent nature of manual handling cannot meet the large-scale, continuous production requirements of stator processing in fields such as new energy motors. Therefore, a stamping forming device for stator processing is provided. Utility Model Content

[0003] The purpose of this application is to provide a stamping forming device for stator processing, which has the characteristics of solving the problems of "cumbersome billet feeding and offset" to reduce scrap rate, solving the problems of "poor coordination between billet transfer and positioning and interruption of production rhythm" to improve processing efficiency, and solving the problems of "scratches on finished products and intermittent handling", and is suitable for large-scale production.

[0004] This application provides a stamping forming apparatus for stator processing, which adopts the following technical solution: It includes a raw material tray, a rotating mechanism, at least two sets of adsorption devices, a stamping die, a conveying mechanism, and a control device. The raw material tray is provided with slots or fixtures for neatly storing stator blanks. The rotating mechanism is horizontally arranged, and the adsorption devices are arranged in a ring at intervals on the upper surface of the rotating mechanism. The stamping die is arranged on one side corresponding to the rotating mechanism, and the processing position of the stamping die is adapted to the transfer path of the adsorption device. The conveying mechanism is arranged on the side of the adsorption device, and the feeding end of the conveying mechanism corresponds to the finished product placement path of the adsorption device. The control device is electrically connected to the rotating mechanism, the adsorption devices, the stamping die, and the conveying mechanism respectively, and is used to control the timing of the actions of each component. By adopting the above technical solution, and by setting up a raw material tray, a rotating mechanism, at least two sets of adsorption devices, a stamping die, a conveying mechanism, and a control device, and by clarifying the positional adaptation relationship of each component, the core intervention links such as manual feeding, manual transfer, and manual collection of traditional devices can be replaced. This achieves basic automation of the entire process of "bill straightening - automatic transfer - stamping processing - finished product conveying", solving the problems of low production efficiency and large quality fluctuations caused by the low degree of automation of traditional devices, and providing a structural foundation for subsequent improvement of precision and efficiency.

[0005] Preferably, the shape of the slots or fixtures on the raw material tray is adapted to the shape of the stator blank, and the bottom of the raw material tray is provided with a lifting mechanism to keep the blank within the picking range of the adsorption device. The lifting mechanism is electrically connected to the control device.

[0006] By adopting the above technical solution, and by adapting the slot / fixture shape of the raw material tray to the shape of the stator blank, the automatic and orderly arrangement of the blank can be directly realized, avoiding the positional deviation that is easy to occur when manually placing blanks in the traditional way, and reducing the source risk of stamping size deviation. At the same time, the lifting mechanism at the bottom of the raw material tray, driven by the control device, can keep the blank within the picking range of the adsorption device at all times, without the need for frequent manual adjustment of the height of the raw material tray or replenishment of the blank position. This solves the problem that the adsorption device cannot accurately pick up blanks when the blanks are reduced in the traditional feeding stage, further reducing manual intervention and ensuring the continuity of the feeding process.

[0007] Preferably, the adsorption device includes a vacuum suction cup and a position sensor. The vacuum suction cup is connected to an external vacuum generating device, and the position sensor is embedded in the adsorption end face of the vacuum suction cup. The position sensor is electrically connected to a control device and is used to detect the coaxiality between the stator blank and the vacuum suction cup.

[0008] By adopting the above technical solution, the adsorption device is set as a combination of a vacuum suction cup and a position sensor. The vacuum suction cup is connected to an external vacuum generating device to achieve stable non-contact gripping of the billet, avoiding the billet damage that may be caused by traditional mechanical gripping. The position sensor embedded in the adsorption end face of the vacuum suction cup can detect the coaxiality between the billet and the vacuum suction cup in real time and feed the signal back to the control device. It can correct the billet picking offset in time, solve the problem of inaccurate billet positioning caused by traditional manual picking or simple adsorption, ensure the subsequent stamping accuracy from the picking stage, and reduce the scrap rate.

[0009] Preferably, the rotating mechanism includes a turntable and a servo motor. The turntable is horizontally arranged, the adsorption device is arranged on the upper surface of the turntable, the output shaft of the servo motor is connected to the central shaft of the turntable, and the servo motor is electrically connected to the control device.

[0010] By adopting the above technical solution, and by setting the rotating mechanism as a combination of a turntable and a servo motor, with the output shaft of the servo motor connected to the central shaft of the turntable, the turntable can be driven to achieve high-precision and stable horizontal rotation, avoiding the turntable speed fluctuations or positioning deviations caused by traditional ordinary motor drives. At the same time, the adsorption device is placed on the upper surface of the turntable. The precise rotation of the turntable can drive the adsorption device to transfer the blanks along a preset path, ensuring that the adsorption device can accurately align with the raw material tray, stamping die, and conveying mechanism, solving the problem of blank alignment deviation caused by the low precision of traditional transfer mechanisms, and providing a stable transfer foundation for process collaboration.

[0011] Preferably, the number of adsorption devices is four sets, which are arranged in a ring at equal intervals along the center of the turntable. The four sets of adsorption devices are divided into two collaborative units, each of which contains two adsorption devices symmetrically arranged along the center of the turntable. The control device is configured such that when one adsorption device in one collaborative unit carries the blank to the processing station of the stamping die, the other adsorption device in the same collaborative unit is positioned at the corresponding position of the conveying mechanism. At the same time, one adsorption device in the other collaborative unit is positioned at the corresponding position of the raw material tray, and the other adsorption device is positioned at the standby position of the stamping die processing station. When the stamping die processes the blank, the control device synchronously drives the turntable to rotate, causing the adsorption device in the standby position to move to the processing station of the stamping die to adsorb the processed stator pieces. Simultaneously, the adsorption device at the corresponding position of the raw material tray picks up the blank, and the adsorption device at the corresponding position of the conveying mechanism places the finished product on the conveying mechanism, thereby achieving synchronous collaboration of blank picking, stamping processing, and finished product handling.

[0012] By adopting the above technical solution, and by setting up four sets of adsorption devices and arranging them at equal intervals in a ring around the center of the turntable, and coordinating with the timing control of the control device, the synchronous coordination of "bill picking-stamping feeding-finished product picking-new billet picking" can be achieved: when one set of coordinating units feeds the billet to the stamping die and places the finished product to the conveying mechanism, another set of coordinating units simultaneously picks up the new billet and waits to pick up the finished product. The stamping and transfer actions are carried out in parallel, solving the problem of production rhythm interruption caused by transfer interruption in traditional devices; at the same time, the symmetrical layout and synchronous action of the four sets of adsorption devices further increases the billet processing capacity per unit time, significantly improves processing efficiency, and adapts to the needs of large-scale production.

[0013] Preferably, the conveying mechanism includes a conveyor belt and a drive motor. The surface of the conveyor belt is covered with a flexible protective layer. The drive motor is connected to the conveyor belt in a transmission connection and is electrically connected to a control device for controlling the start and stop of the conveyor belt and the conveying speed.

[0014] By adopting the above technical solution, and by setting the conveying mechanism as a combination of conveyor belt, drive motor and flexible protective layer, the flexible protective layer on the surface of the conveyor belt can avoid surface scratches caused by hard contact between the finished stator pieces and the conveyor belt, thus solving the problem of damage to the appearance and performance of finished products caused by traditional manual handling; the drive motor can accurately control the start and stop and speed of the conveyor belt under the drive of the control device, so that the conveying rhythm is matched with the stamping rhythm, realizing the continuous transfer of finished products, avoiding the production bottleneck caused by traditional intermittent manual handling, and ensuring the continuous operation of the whole process.

[0015] Preferably, the control device includes a PLC controller and a touch screen. The PLC controller is electrically connected to the rotating mechanism, the adsorption device, the stamping die, and the conveying mechanism, respectively, and is used to receive signals from each component and output control commands. The touch screen is electrically connected to the PLC controller and is used to display the equipment operating status and input parameters.

[0016] By adopting the above technical solution, and by setting the control device as a combination of a PLC controller and a touch screen, the PLC controller can receive signals from various components such as the rotating mechanism and the adsorption device in real time and output precise control commands, realizing the timing coordination of the actions of various components and avoiding the action misalignment or delay caused by traditional manual control; the touch screen is electrically connected to the PLC controller, which can intuitively display the equipment operating status and conveniently input adjustment parameters, solving the problems of opaque status and cumbersome parameter adjustment during the operation and maintenance of traditional devices, improving the convenience of equipment management and control, and reducing production failures caused by improper operation and maintenance.

[0017] Preferably, the turntable is equipped with an angle sensor, which is electrically connected to the control device to detect the rotation angle of the turntable and feed it back to the control device to adjust the transfer position accuracy of the adsorption device.

[0018] By adopting the above technical solution, an angle sensor is installed on the turntable. The angle sensor can detect the rotation angle of the turntable in real time and feed the signal back to the control device. The control device dynamically corrects the speed and direction of the servo motor accordingly, avoiding rotation angle deviations caused by mechanical errors or load changes. This structure and the servo motor form a closed-loop control of "drive-detection-correction", which further improves the transfer position accuracy of the adsorption device, ensuring that the blank can be accurately placed on the stamping die processing station and the finished product can be accurately placed on the conveying mechanism. This solves the positioning deviation problem that may exist in traditional methods that rely solely on servo motor drive, and further reduces the risk of stamping size deviations and finished product placement errors.

[0019] In summary, this application includes at least one of the following beneficial technical effects: 1. This stamping forming device for stator processing utilizes a raw material tray, a lifting mechanism, a vacuum suction cup of an adsorption device, and a position sensor. The stator blank is first placed into a slot or fixture in the raw material tray. Because the slot / fixture is adapted to the blank's shape, it directly achieves a neat arrangement of the blank, replacing manual piece-by-piece handling. As the blank is picked up and reduced, the lifting mechanism at the bottom of the raw material tray automatically adjusts its height under the drive of the control device, ensuring that the remaining blank remains within the adsorption device's picking range. When the adsorption device is working, the vacuum suction cup connects to an external vacuum generator to grab the blank. The position sensor embedded in the suction cup's adsorption end face detects the coaxiality between the blank and the vacuum suction cup in real time and feeds the signal back to the control device. If any deviation occurs, it is adjusted promptly to ensure accurate blank picking position, completely replacing manual feeding and avoiding blank position deviation caused by manual placement. This reduces stamping dimensional deviations from the source and lowers the risk of scrap. Simultaneously, it eliminates the need for frequent manual replenishment and adjustment, reducing interference with the production rhythm during the feeding process. 2. This stamping forming device for stator processing comprises a turntable of a rotating mechanism, a servo motor, four sets of adsorption devices, and an angle sensor. The four sets of adsorption devices are arranged in a ring at equal intervals around the center of the turntable and divided into two coordinating units. The control device drives the servo motor, causing its output shaft to rotate the turntable horizontally. When one adsorption device in one coordinating unit carries the blank to the stamping die processing station, the other adsorption device in that unit simultaneously moves to the corresponding position on the conveying mechanism. In the other coordinating unit, one adsorption device is positioned on the corresponding position of the raw material tray to pick up a new blank, while the other is on standby at the stamping die processing station. When the stamping die begins processing the blank, the control device synchronously drives the turntable to rotate, and the standby adsorption device immediately moves to the processing station to adsorb the finished product. The adsorption device on the raw material tray simultaneously picks up a new blank, and the adsorption device on the conveying mechanism simultaneously places the finished product onto the conveyor belt. Simultaneously, the angle sensor on the turntable detects the turntable's rotation angle in real time and feeds the signal back to the control device, dynamically adjusting the transfer position of the adsorption devices to ensure precise alignment for each transfer.

[0020] 3. This stamping forming device for stator processing, via a conveyor belt, a flexible protective layer, and a drive motor, allows stamped stator wafers to be picked up by an adsorption device and transported to the feed end of the conveyor mechanism. The adsorption device releases a vacuum, causing the finished product to fall onto the conveyor belt. The flexible protective layer covering the surface of the conveyor belt directly contacts the finished product, avoiding surface scratches caused by hard contact. The control device drives the drive motor, causing the drive motor to drive the conveyor belt at a speed adapted to the stamping rhythm, continuously conveying the finished product to the next process. This eliminates the need for manual handling, replacing traditional manual handling. It not only eliminates surface scratches caused by contact friction, ensuring the appearance and performance of the stator, but also adapts to the large-scale and continuous requirements of stator processing in the new energy motor field through continuous conveying, reducing labor costs and management difficulties.

Detailed Implementation

[0023] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0024] Example 1: A stamping forming apparatus for stator processing, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a raw material tray 1, a rotating mechanism 2, at least two sets of adsorption devices 3, a stamping die 4, a conveying mechanism 5, and a control device 6. The raw material tray 1 has slots or fixtures for neatly storing stator blanks. The rotating mechanism 2 is horizontally positioned. The adsorption devices 3 are arranged in a ring at intervals on the upper surface of the rotating mechanism 2. The stamping die 4 is positioned on one side of the rotating mechanism 2, and its processing position is adapted to the transfer path of the adsorption devices 3. The conveying mechanism 5 is located on the side of the adsorption devices 3, and its feed end corresponds to the finished product placement path of the adsorption devices 3. The control device 6 is connected to the rotating mechanism 2, the adsorption device 3, and the stator blanks 3. The device 3, stamping die 4, and conveying mechanism 5 are electrically connected to control the timing of the actions of each component. By setting up the raw material tray 1, rotating mechanism 2, at least two sets of adsorption devices 3, stamping die 4, conveying mechanism 5, and control device 6, and clarifying the positional adaptation relationship of each component, it can replace the core intervention links of manual feeding, manual transfer, and manual collection in traditional devices, and realize the basic automation connection of the entire process of "bill straightening - automatic transfer - stamping processing - finished product conveying". It solves the problems of low production efficiency and large quality fluctuation caused by the low degree of automation of traditional devices, and provides a structural foundation for subsequent improvement of precision and efficiency.

[0025] Reference Figure 1 , Figure 2 and Figure 4 The shape of the slots or fixtures on the raw material tray 1 is adapted to the shape of the stator blank. A lifting mechanism 7 is provided at the bottom of the raw material tray 1 to keep the blank within the pickup range of the adsorption device 3. The lifting mechanism 7 is electrically connected to the control device 6. The adsorption device 3 includes a vacuum suction cup 301 and a position sensor 302. The vacuum suction cup 301 is connected to an external vacuum generator. The position sensor 302 is embedded in the adsorption end face of the vacuum suction cup 301 and is electrically connected to the control device 6. It is used to detect the coaxiality between the stator blank and the vacuum suction cup 301. By adapting the shape of the slots / fixtures on the raw material tray 1 to the shape of the stator blank, automatic and orderly arrangement of the blank can be directly achieved, avoiding the positional deviation that easily occurs when manually placing blanks in traditional methods, and reducing the source risk of stamping dimensional deviations. Simultaneously, the lifting mechanism 7 at the bottom of the raw material tray 1, driven by the control device 6, enables... The billet is always within the picking range of the adsorption device 3, eliminating the need for frequent manual adjustments to the height of the raw material tray 1 or replenishment of the billet position. This solves the problem of the adsorption device 3 being unable to accurately pick up the billet due to a decrease in the billet during the traditional feeding stage, further reducing manual intervention and ensuring the continuity of the feeding process. By setting the adsorption device 3 as a combination of a vacuum suction cup 301 and a position sensor 302, the vacuum suction cup 301 can be connected to an external vacuum generator to achieve stable non-contact gripping of the billet, avoiding the billet damage that may be caused by traditional mechanical gripping. The position sensor 302, embedded in the adsorption end face of the vacuum suction cup 301, can detect the coaxiality between the billet and the vacuum suction cup 301 in real time and feed the signal back to the control device 6, which can correct the billet picking offset in time, solving the problem of inaccurate billet positioning caused by traditional manual picking or simple adsorption. This ensures the subsequent stamping accuracy from the picking stage and reduces the scrap rate.

[0026] Reference Figure 1 , Figure 2 and Figure 3The rotating mechanism 2 includes a turntable 201 and a servo motor 202. The turntable 201 is horizontally positioned, and the adsorption devices 3 are arranged on the upper surface of the turntable 201. The output shaft of the servo motor 202 is connected to the central shaft of the turntable 201, and the servo motor 202 is electrically connected to the control device 6. There are four sets of adsorption devices 3, which are arranged in a ring at equal intervals along the center of the turntable 201. The four sets of adsorption devices 3 are divided into two cooperating units, each containing two adsorption devices 3 symmetrically arranged along the center of the turntable 201. The control device 6 is configured such that when one of the adsorption devices 3 in one of the cooperating units carries the blank to the processing station of the stamping die 4, In this collaborative unit, another adsorption device 3 is positioned corresponding to the conveying mechanism 5. Simultaneously, in another collaborative unit, one adsorption device 3 is positioned corresponding to the raw material tray 1, and the other adsorption device 3 is positioned in a standby position at the processing station of the stamping die 4. When the stamping die 4 processes the blank, the control device 6 synchronously drives the turntable 201 to rotate, causing the adsorption device 3 in the standby position to move to the processing station of the stamping die 4 to adsorb the processed stator wafers. Simultaneously, the adsorption device 3 in the raw material tray 1 picks up the blank, and the adsorption device 3 in the conveying mechanism 5 places the finished product onto the conveying mechanism 5, thus realizing blank picking and stamping processing. The synchronous and coordinated handling of finished product loading and unloading is achieved by combining the rotating mechanism 2 with a turntable 201 and a servo motor 202. The output shaft of the servo motor 202 is connected to the central shaft of the turntable 201, enabling the turntable 201 to achieve high-precision and stable horizontal rotation. This avoids the speed fluctuations or positioning deviations of the turntable 201 caused by traditional ordinary motor drives. Simultaneously, the adsorption device 3 is positioned on the upper surface of the turntable 201. The precise rotation of the turntable 201 drives the adsorption device 3 to transfer the blank along a preset path, ensuring that the adsorption device 3 can accurately align with the raw material tray 1, the stamping die 4, and the conveying mechanism 5. This solves the problem of blank alignment deviation caused by the low precision of traditional transfer mechanisms, providing stable coordination for the process. The transfer system, by setting up four sets of adsorption devices 3 and arranging them at equal intervals in a ring around the center of turntable 201, and coordinating with the timing control of control device 6, can achieve synchronous coordination of "bill picking-stamping feeding-finished product picking-new billet picking": when one set of coordinating units sends the billet to the stamping die 4 and places the finished product to the conveying mechanism 5, another set of coordinating units simultaneously picks up the new billet and waits to pick up the finished product. The stamping and transfer actions are carried out in parallel, solving the problem of production rhythm interruption caused by transfer interruption in traditional devices; at the same time, the symmetrical layout and synchronous action of the four sets of adsorption devices 3 further increases the billet processing capacity per unit time, significantly improves processing efficiency, and adapts to the needs of large-scale production.

[0027] Reference Figure 1 , Figure 2 and Figure 5The conveying mechanism 5 includes a conveyor belt 501 and a drive motor 502. The surface of the conveyor belt 501 is covered with a flexible protective layer 9. The drive motor 502 is connected to the conveyor belt 501 and is electrically connected to the control device 6 to control the start and stop of the conveyor belt 501 and the conveying speed. The control device 6 includes a PLC controller 601 and a touch screen 602. The PLC controller 601 is electrically connected to the rotating mechanism 2, the adsorption device 3, the stamping die 4, and the conveying mechanism 5, respectively, and is used to receive signals from each component and output control commands. The touch screen 602 is electrically connected to the PLC controller 601 and is used to display the equipment operating status and input parameters. An angle sensor is provided on the turntable 201. Sensor 8, an angle sensor, is electrically connected to the control device 6. It is used to detect the rotation angle of the turntable 201 and feed it back to the control device 6 to adjust the transfer position accuracy of the adsorption device 3. By setting the conveying mechanism 5 as a combination of conveyor belt 501, drive motor 502, and flexible protective layer 9, the flexible protective layer 9 on the surface of the conveyor belt 501 can avoid surface scratches caused by hard contact between the finished stator fragments and the conveyor belt 501, solving the problem of damage to the appearance and performance of finished products caused by traditional manual handling. Under the drive of the control device 6, the drive motor 502 can accurately control the start, stop, and speed of the conveyor belt 501, so that the conveying rhythm is matched with the stamping rhythm, realizing continuous transfer of finished products and avoiding the intermittent handling of traditional manual handling. To address production bottlenecks caused by improper operation and ensure continuous operation throughout the entire process, the control device 6 is configured as a combination of a PLC controller 601 and a touch screen 602. The PLC controller 601 can receive signals from various components such as the rotating mechanism 2 and the adsorption device 3 in real time and output precise control commands, achieving synchronized action of each component and avoiding misalignment or delay caused by traditional manual control. The touch screen 602 is electrically connected to the PLC controller 601, providing a clear display of the equipment's operating status and convenient input of adjustment parameters. This solves the problems of opaque status and cumbersome parameter adjustments in traditional equipment maintenance, improving the convenience of equipment management and reducing production failures caused by improper maintenance. This is achieved through the rotary table 2... An angle sensor 8 is installed on the turntable 201. The angle sensor 8 can detect the rotation angle of the turntable 201 in real time and feed the signal back to the control device 6. The control device 6 dynamically corrects the speed and direction of the servo motor 202 accordingly, avoiding rotation angle deviation of the turntable 201 due to mechanical errors or load changes. This structure and the servo motor 202 form a closed-loop control of "drive-detection-correction", which further improves the transfer position accuracy of the adsorption device 3, ensuring that the blank can be accurately dropped to the processing station of the stamping die 4 and the finished product can be accurately placed on the conveying mechanism 5. This solves the positioning deviation problem that may exist in the traditional method of relying solely on the servo motor 202 for drive, and further reduces the risk of stamping size deviation and finished product placement error.

[0028] In this embodiment, the stator blank is first placed into the slot or fixture of the raw material tray 1 via the raw material tray 1, the lifting mechanism 7, the vacuum suction cup 301 of the adsorption device 3, and the position sensor 302. Because the slot / fixture is adapted to the shape of the blank, the blank is directly arranged in a regular manner, replacing manual sorting piece by piece. As the blank is picked up and the amount decreases, the lifting mechanism 7 at the bottom of the raw material tray 1 automatically adjusts its height under the drive of the control device 6 to ensure that the remaining blank is always within the picking range of the adsorption device 3. When the adsorption device 3 is working, the vacuum suction cup 301 is connected to an external vacuum generating device to grab the blank. The position sensor 302 embedded in the adsorption end face of the suction cup detects the coaxiality between the blank and the vacuum suction cup 301 in real time and feeds the signal back to the control device 6. If there is a deviation, it is adjusted in time to ensure that the blank picking position is accurate, completely replacing manual feeding, avoiding blank position deviation caused by manual placement, reducing stamping size deviation from the source, and reducing the risk of scrap generation. At the same time, there is no need for frequent manual replenishment and adjustment, reducing the interference of the feeding process on the production rhythm.

[0029] The implementation principle of this application embodiment is as follows: Stator blanks are manually placed one by one into the slots or fixtures of the raw material tray 1. Because the shape of the slots / fixtures matches the shape of the stator blanks, the blanks are automatically and neatly arranged, eliminating the need for manual adjustment of each blank. The control device 6 sends an initial height adjustment command to the lifting mechanism 7 via the PLC controller 601. The lifting mechanism 7 drives the raw material tray 1 to move up or down, so that the uppermost blank is exactly within the picking range of the adsorption device 3. The lifting mechanism 7 then maintains the current height, waiting for the adsorption device 3 to pick up the blank. The control device 6 drives the servo motor 202 to operate, and the output shaft of the servo motor 202 drives the turntable 201 to rotate horizontally, causing one of the adsorption devices 3 in one of the cooperating units to move directly above the raw material tray 1. The vacuum suction cup 301 of the device is connected to an external vacuum generator to create negative pressure to adsorb the blank in the raw material tray 1. Simultaneously, the position sensor 302 embedded in the adsorption end face of the vacuum suction cup 301 detects the coaxiality between the blank and the vacuum suction cup 301 in real time. If a misalignment is detected, the position sensor 302 feeds a signal back to the PLC controller 601. The PLC controller 601 fine-tunes the angle of the turntable 201 until the blank and the vacuum suction cup 301 are coaxial, ensuring accurate pickup position. After pickup, the PLC controller 601 drives the servo motor 202 again, causing the turntable 201 to move the adsorption device 3 carrying the blank to the processing station of the stamping die 4. During the transfer process, the angle sensor 8 on the turntable 201 detects the rotation angle of the turntable 201 in real time. The signal is fed back to the PLC controller 601, which dynamically corrects the speed and direction of the servo motor 202 to prevent the adsorption device 3 from shifting due to the rotation deviation of the turntable 201. When the adsorption device 3 carrying the blank rotates to directly above the processing station of the stamping die 4, the angle sensor 8 detects that the turntable 201 has reached the preset angle and sends a "positioning signal" to the PLC controller 601. The PLC controller 601 immediately controls the servo motor 202 to stop, the turntable 201 remains stationary, and at the same time controls the adsorption device 3 to release the vacuum, so that the blank falls precisely into the processing station of the stamping die 4. At this time, another adsorption device 3 in the same cooperative unit rotates synchronously to directly above the feeding end of the conveying mechanism 5, and another adsorption device 3 in another cooperative unit rotates to its original position. Above the material tray 1, another adsorption device 3 rotates to a standby position next to the processing station of the stamping die 4; after the PLC controller 601 confirms that the blank is in place, it sends a "processing instruction" to the stamping die 4, and the stamping die 4 starts and completes the stamping and forming of the stator blank; after the stamping die 4 completes the processing and resets, the PLC controller 601 drives the servo motor 202 to drive the turntable 201 to rotate synchronously: the adsorption device 3, which is in the standby position of the stamping die 4, moves to the top of the processing station, and the vacuum suction cup 301 starts to adsorb the processed stator pieces; the adsorption device 3, which is above the material tray 1, simultaneously completes the picking up of new blanks; the adsorption device 3, which is above the conveying mechanism 5, simultaneously releases the vacuum, and the previously adsorbed finished products fall onto the conveyor belt 501;The PLC controller 601 sends a "conveyor command" to the drive motor 502, which in turn drives the conveyor belt 501. The flexible protective layer 9 on the surface of the conveyor belt 501 prevents surface scratches caused by hard contact between the stator fragments and the conveyor belt 501. The finished product is continuously conveyed to the next process along with the conveyor belt 501. After the above "bill picking-transfer-stamping-finished product conveying" steps are completed, the PLC controller 601 controls the turntable 201 to continue rotating, entering the next cycle: the adsorption device 3 that picks up new billets transfers them to the stamping die 4, and the adsorption device 3 that adsorbs new finished products transfers them to the conveying mechanism 5. Another set of adsorption devices 3 continues to pick up new billets, achieving seamless connection of processes.
