Description

Technical Field

[0001] This utility model relates to the field of automated equipment technology, specifically to an automatic stacking and unloading mechanism for stator laminations. Background Technology

[0002] Stator laminations are an important component of motor stators. They are usually made of silicon steel sheets by stamping. First, the silicon steel sheet rolls are stamped using equipment such as a punch press. The shape and slots of the stator laminations are punched out according to the designed mold. The stamping process requires high precision to ensure the dimensional accuracy and consistency of the laminations, thereby ensuring the stable performance of the motor.

[0003] Stamped stator laminations usually need to be stacked. During stacking, the stator laminations are usually stacked together manually, one by one. However, manual stacking has limited speed, especially in large-scale production, which makes it difficult to meet the needs of rapid production and increases production costs. Therefore, it is necessary to provide an automatic stacking and unloading mechanism for stator laminations. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic stator lamination stacking and unloading mechanism to solve the problem mentioned in the background art that the current method of stacking stator laminations is usually done manually, one lamination at a time. However, manual stacking has limited speed, especially in large-scale production, making it difficult to meet the demands of rapid production and increasing production costs. To achieve the above objective, this utility model provides the following technical solution: an automatic stator lamination stacking and unloading mechanism, including a frame:

[0005] The stacking assembly includes a support frame, which is fixedly connected to the top of the frame. A support base is fixedly connected to the top of the support frame. A guide roller is movably connected to one side of the support base. A drive roller is movably connected to the bottom of the guide roller. The drive roller is movably connected to one side of the support frame. A conveyor belt is movably connected to the side surface of the drive roller. After the stator lamination body is stamped by the stamping machine, it is transported to the unloading mechanism by the conveyor belt. The stator lamination bodies are transported and stacked one by one on the central column. A second drive roller is movably connected to the inner wall of the conveyor belt.

[0006] The unloading assembly includes an unloading cylinder 1 for unloading. The piston rod of the unloading cylinder 1 extends to push the stator lamination body along the conveying roller, realizing the automatic stacking and unloading of the stator lamination body. The unloading cylinder 1 is located at the top of the frame. The inner wall of the frame is fixedly connected to the unloading cylinder 2. When the stator lamination bodies are stacked on the central column, the stator lamination bodies will be located above the conveying roller. When the stator lamination bodies are stacked to a certain number, the unloading cylinder 2 below the central column will retract downward, causing the central column to move downward and separate from the stator lamination bodies. The top of the unloading cylinder 2 is fixedly connected to the central column. The top of the frame is provided with conveying rollers.

[0007] Further preferably, the stacking assembly also includes a support plate, which is fixedly connected to the top of the support frame. A support block is fixedly connected to the bottom of the support plate. A connecting rod is fixedly connected to the bottom of the support frame. A connecting plate is fixedly connected to one end of the connecting rod. A guide wheel is movably connected to one side of the connecting plate. The two guide wheels facilitate the smooth sliding of the stator lamination bodies from the conveyor belt onto the central column for sequential stacking. A support rod is fixedly connected to the top of the support frame. A limit baffle is fixedly connected to one end of the support rod. A support rod is fixedly connected to the bottom of the support frame. A limit baffle is fixedly connected to one end of the support rod. Limit baffles one and two are installed on the support frame. When the stator lamination body passes the guide roller, the limit baffles one and two will limit the stator lamination body, facilitating the centered insertion of the stator lamination body onto the central column. By installing the stacking assembly, not only is the stacking efficiency improved, but labor and production costs are also reduced, thus improving the practicality of the device.

[0008] More preferably, the unloading assembly further includes a connecting seat one, which is fixedly connected to the top of the frame. The unloading cylinder one is fixedly connected to the inner wall of the connecting seat one, and an unloading plate is fixedly connected to one end of the unloading cylinder one. A stator lamination body is sleeved on the side surface of the central column. A reinforcing plate is fixedly connected to the top of the frame. A connecting seat two is fixedly connected to one side of the reinforcing plate. The conveying roller is movably connected to the inner wall of the connecting seat two. By installing the unloading assembly, manual stacking of each lamination is eliminated, improving efficiency and saving labor.

[0009] More preferably, a switch plate is fixedly connected to one side of the frame, and a switch button is movably connected to the front of the switch plate.

[0010] More preferably, the bottom of the support block is fixedly connected to a support leg, and the bottom of the support leg is fixedly connected to a reinforcing plate.

[0011] More preferably, a first reinforcing block is fixedly connected to the top of the support frame, and a second reinforcing block is fixedly connected to the top of the support frame.

[0012] More preferably, the support plate is movably connected to the inner wall of the conveyor belt, and the drive roller is movably connected to one side of the support block.

[0013] More preferably, the stator lamination body is movably connected to the top of the conveyor belt, and the stator lamination body is movably connected to the side surface of the conveyor roller.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this invention, by installing a stacking assembly, the stator lamination body is conveyed to the unloading mechanism via a conveyor belt after being stamped by the stamping machine. The stator lamination bodies are stacked one by one on the central column. Limiting baffle one and limiting baffle two are installed on the support frame. When the stator lamination body passes the guide roller, the limiting baffle one and limiting baffle two will limit the stator lamination body, which is conducive to the stator lamination body being inserted into the central column in a centered position. At the same time, the two guide rollers facilitate the stator lamination body to slide smoothly from the conveyor belt onto the central column and be stacked in sequence. This not only improves the stacking efficiency, but also reduces labor costs and production costs, and improves the practicality of the device.

[0016] In this invention, by installing a feeding assembly, when the stator laminations are stacked on the central column, the stator laminations are positioned above the conveying rollers. When a certain number of stator laminations are stacked, the unloading cylinder two below the central column retracts downwards, causing the central column to move downwards and separate from the stator laminations. Then, the piston rod of the unloading cylinder one extends, pushing the stator laminations along the conveying rollers, thus achieving automatic stacking and unloading of the stator laminations. This eliminates the need for manual stacking of each lamination, improving efficiency and saving labor. Attached Figure Description

The top of the support frame 201 is fixedly connected to... There is a support rod 212, one end of which is fixedly connected to a limit baffle 213. The bottom of the support frame 201 is fixedly connected to a support rod 214, one end of which is fixedly connected to a limit baffle 215. The support frame 201 is equipped with limit baffle 213 and limit baffle 215. When the stator lamination body 307 passes the guide roller 203, the limit baffle 213 and limit baffle 215 will limit the stator lamination body 307, which is conducive to the stator lamination body 307 being inserted into the center column 303 in a centered position.

Simultaneously, as the stator lamination bodies 307 are stacked on the central column 303, they are positioned above the conveying roller 304. Once a certain number of stator lamination bodies 307 are stacked, the unloading cylinder 302 below the central column 303 retracts downward, causing the central column 303 to move downward and separate from the stator lamination bodies 307. Then, the piston rod of the unloading cylinder 301 extends, pushing the stator lamination bodies 307 along the conveying roller 304, thus achieving automatic stacking and automatic unloading of the stator lamination bodies 307.
