Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, and more specifically, to a multi-station motor core lamination device. Background Technology

[0002] Lamination of motor cores refers to a process in which thin sheets of silicon steel are stacked together to form the core of a motor. The main purpose of this process is to reduce eddy current losses and hysteresis losses, thereby improving the efficiency and performance of the motor. Existing lamination devices primarily use a robotic arm to directly place the silicon steel sheets stored in the equipment into a pressing device one by one. Once the pressing device is full, the pressing process is then initiated. However, with this type of lamination device, some silicon steel sheets may have been contaminated with debris or other impurities during transportation and storage. Directly laminating these sheets can affect the bonding quality between the core and the coil, and may even lead to motor overheating. Utility Model Content

[0020] 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.

[0021] like Figures 1 to 5 As shown, this utility model provides a multi-station motor core lamination device, including a platform 1. Along its length, the platform 1 has a storage station, a cleaning station, and a pressing station arranged in sequence. A storage device 2 is installed at the storage station, and a pressing device 3 is installed at the cleaning station. A vertical shaft 6 is rotatably installed at the cleaning station, and a drive motor 8 is connected to the vertical shaft 6. Several horizontal arms are fixedly installed circumferentially on the outer surface of the vertical shaft 6. A frustum 7 is fixedly installed at the end of each horizontal arm. Several positioning rods 13 are installed on the upper surface of the frustum 7. A first cavity 9 is opened inside the frustum 7, and several first air outlets 10 are opened through the upper surface of the frustum 7. A duct 12 connected to the first cavity 9 is also fixed on the frustum 7. A cover 14 is installed above the vertical shaft 6, and the cover 14 is made of transparent acrylic material. The use of the transparent acrylic cover 14 allows for clear observation of the blowing process of the silicon steel sheets. The cover 14 is mounted on the lifter 20, and the movement path of the cover 14 corresponds to that of the truncated cone 7. The lifter 20 includes a long-stroke cylinder, the output end of which is fixedly connected to the cover 14, and the long-stroke cylinder is fixed on the platform 1 by a bracket.

[0022] The first robotic arm 4 and the second robotic arm 5 are respectively installed on the platform 1 between the material storage station and the cleaning station, and between the cleaning station and the pressing station.

[0023] Several support rods 11 are fixedly installed on the upper surface of the frustum 7. The length of the support rods 11 is less than the length of the positioning rods 13. The support rods 11 are used to support the silicon steel sheets.

[0024] The cover 14 is equipped with an insertion tube 17 corresponding to the air guide tube 12, so that the air guide tube 12 can be aligned with the insertion tube 17 during movement. A second cavity 15 is formed at the top of the cover 14, and several second air outlets 16 communicating with the second cavity 15 are formed on the inner wall of the cover 14. An air inlet pipe 18 communicating with the second cavity 15 is provided on the cover 14, and the air inlet pipe 18 is used to connect to an air supply device. Several exhaust assemblies 19 communicating with the interior are arranged circumferentially on the outer wall of the cover 14, and the exhaust assemblies 19 are used to connect to a gas purification device. Gas discharged through the upper and lower air outlets can achieve more efficient gas purging.

[0025] A sealing sleeve is coaxially fixed to the end of the cannula 17. The sealing sleeve is used to improve the sealing between the cannula 17 and the air delivery tube 12 to prevent gas leakage during the purging process.

[0026] The exhaust assembly 19 includes a gas guide and an exhaust pipe. The gas guide is fan-shaped, with its inner arc side connected to the cover 14. The exhaust pipe is connected to the outer end of the gas guide. Since the silicon steel sheet is purged simultaneously from both top and bottom directions using the first exhaust port 10 and the second exhaust port 16, impurities blown off the silicon steel sheet are blown out in all directions around the silicon steel sheet. To achieve this, multiple exhaust pipes are arranged circumferentially on the outer wall of the cover 14. The exhaust pipes collect the blown-off impurities more efficiently through the large inlet of the fan-shaped gas guide, and then discharge them through the exhaust pipes, thus achieving more efficient discharge of impurities and preventing impurities from remaining inside the cover 14 and contaminating the silicon steel sheet.

[0027] In use, the stacked silicon steel sheets are stored in a storage container at the pressing station. During the stacking process, the first robotic arm 4 picks up the silicon steel sheets from the storage container and places them onto any truncated cone 7 at the cleaning station. Then, the drive motor 8 drives the vertical shaft 6 to rotate, which rotates the truncated cone 7 containing the silicon steel sheets to directly below the cover 14. At this point, the drive motor 8 is stopped, and the long-stroke cylinder pushes the cover 14 to cover the truncated cone 7. During this process, the insertion tube 17 on the cover 14 is inserted into the air guide tube 12 on the truncated cone 7, thereby connecting the first cavity 9 and the second cavity 15. Then, the air supply device is activated, and high-pressure gas is input into the first cavity 9 and the second cavity 15. Finally, the gas passes through the truncated cone 7. The first vent 10 on the top and the second vent 16 on the cover 14 spray out simultaneously, thus blowing the silicon steel sheets on the frustum 7 from both the top and bottom directions. The impurities blown out will enter the exhaust components 19 distributed in a ring on the inner wall of the cover 14. After the blowing is completed, the long-stroke cylinder drives the cover 14 to reset, and then the drive motor 8 continues to drive the vertical shaft 6 to rotate, so that the blown silicon steel sheets will be moved by the frustum 7 to the pressing station. Then the drive motor 8 is stopped, and the second robot arm 5 puts the blown silicon steel sheets into the pressing station. The above operation is repeated many times until the silicon steel sheets in the pressing station are stacked to a specified number. Then the presser in the pressing station is controlled to press the silicon steel sheets, thus completing the stacking process of the iron core.
