Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, specifically, it demonstrates a stator conveying and transfer mechanism for a motor production line. Background Technology

[0002] Throughout the entire manufacturing and assembly process of an electric motor, the motor stator needs to be transferred and assembled between different assembly lines. Precise positioning is required during assembly and placement to assemble it with other parts. Currently, some of the transfer methods rely on manual handling. Manual handling has drawbacks such as high labor costs, high fatigue levels, and low efficiency. Furthermore, during placement, the stator is prone to slipping, causing product damage and unnecessary losses. Utility Model Content

[0003] The purpose of this invention is to provide a conveying and transfer mechanism for stators in a motor production line. It has a simple and practical structure and good handling efficiency.

[0004] The technical solution is as follows:

[0005] A stator conveying and transfer mechanism for an electric motor production line includes a frame, on which are mounted the following:

[0006] A roller conveyor is provided with a pusher on its first side to push the products on the roller conveyor out from the second side of the roller conveyor for unloading;

[0007] The intermediate platform, located on the second side of the roller conveyor, has an opening in the middle;

[0008] The receiving seat is used to receive products unloaded from the roller conveyor. The receiving seat is located in the opening of the intermediate platform and can move up and down relative to the opening through a lifting component.

[0009] The clamping assembly is used to clamp the product on the receiving seat. The clamping assembly is located above the intermediate platform and moves laterally relative to the intermediate platform through a linear displacement module.

[0010] In addition, the above embodiments of this utility model may also have the following additional technical features:

[0011] According to one embodiment of the present invention, the lifting assembly includes:

[0012] A bracket is attached to the frame;

[0013] The lifting cylinder is mounted on a bracket, and a mounting plate is provided on its lifting end.

[0014] Adjust the column, whose top end is connected to the receiving seat, and whose bottom end is rotatably mounted on the mounting plate via a bearing component;

[0015] The fine-tuning cylinder has one end hinged to the top surface of the mounting plate and the other output end hinged to the bottom surface of the adjusting column.

[0016] The lifting cylinder provides the main lifting force, allowing the receiving seat to move up and down within the opening to accommodate stators of different heights or the needs of the next station (such as raising the stator to a height easily gripped by the clamping assembly); the adjusting column is connected to the mounting plate via bearing components, allowing the fine-tuning cylinder to make angular adjustments, which can correct slight angular deviations of the stator on the receiving seat.

[0017] In one embodiment, the top of the receiving seat is constructed as a sleeve with a diameter that gradually decreases from top to bottom. The tapered design of the sleeve provides a guiding function, and the gradually decreasing diameter guides the stator to automatically center itself as it is pushed off the roller conveyor and falls onto the receiving seat.

[0018] According to one embodiment of the present invention, the clamping assembly includes a support frame and a bidirectional cylinder mounted on the support frame. Each end of the bidirectional cylinder has a displacement plate, and the inner side of each displacement plate has a pair of mirror-symmetrical vertical clamping bodies. The bidirectional cylinder simultaneously drives the two displacement plates to move towards the center or to the sides, causing the vertical clamping bodies to mirror-grip or release the stator.

[0019] In one embodiment, a limiting stop is provided at the bottom end of each of the vertical clamps. The limiting stop forms a "bottom support" structure when clamping. When the vertical clamp clamps the stator sidewall, the stop blocks the bottom of the stator from below, preventing it from falling or slipping under the action of gravity.

[0020] According to one embodiment of the present invention, a pair of protruding guide flanges are provided on the top surface of the intermediate platform, and the guide flanges are distributed on both sides of the opening. The guide flanges form a guide channel on both sides of the opening. When the stator is pushed out from the roller conveyor to the intermediate platform, the flanges constrain the movement direction of the stator and prevent it from deviating or running out of the platform area.

[0021] According to one embodiment of this utility model, the conveying plane of the roller conveyor is flush with the top surface of the intermediate platform. A pushing cylinder connected to the pusher is provided on the outer side of the roller conveyor. The movement direction of the pusher is perpendicular to the conveying direction of the roller conveyor and faces the opening direction. The flush design eliminates the height difference, and the pusher pushes the stator in a straight line, with a short and direct path, smoothly pushing the stator to the corresponding position on the intermediate platform.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] 1. Roller conveyors automatically transport stators and automatically unload parts, replacing manual handling. Workers no longer need to manually move the stators, reducing labor intensity and fatigue risk, making them especially suitable for high-intensity production lines.

[0024] 2. The receiving seat adjusts its height through the lifting component and works in conjunction with the clamping component to ensure that the stator is stably supported during transportation, avoiding the risk of slippage or collision during manual handling;

[0025] 3. The combination of clamping components and linear displacement modules enables precise control of the stator's lateral movement, ensuring that the stator can be accurately placed at the next assembly station and improving assembly quality. Attached Figure Description

Detailed Implementation

[0031] 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.

[0032] Example 1

[0033] See Figure 1 As shown in the figure, this utility model embodiment proposes a conveying and transfer mechanism for the stator of an electric motor production line, including a frame 1, and a roller conveyor 2, an intermediate platform 3, a receiving seat 4, and a clamping assembly 6 arranged on the frame 1.

[0034] See Figure 1 and Figure 2 As shown, the roller conveyor 2 is fixed horizontally on one side of the frame 1. The conveying plane of the roller conveyor 2 is perpendicular to the frame 1. A pusher 21 is provided on the first side of the roller conveyor 2 (i.e., the right side of the figure). The pusher 21 is connected to the output end of a push cylinder 22, which is fixed on the outside of the roller conveyor 2. The movement direction of the pusher 21 is perpendicular to the conveying direction of the roller conveyor 2. The pusher 21 is used to push the products on the roller conveyor 2 out from the second side of the roller conveyor 2 for unloading. To ensure the smooth unloading operation, the conveying end of the roller conveyor needs to be designed with a certain limit and blocking to prevent the stator products from accidentally rushing out of the roller conveyor.

[0035] See Figure 2 As shown, the intermediate platform 3 is located on the second side of the roller conveyor 2 (i.e., on the left side of the diagram), and an opening 31 is provided in the middle of the intermediate platform 3. The conveying plane of the roller conveyor 2 is flush with the top surface of the intermediate platform 3. The movement direction of the pusher 21 is towards the opening 31, meaning that the pusher 21 can push the stator product from the roller conveyor 2 to the opening 31. When the stator reaches the end of the roller conveyor, the cylinder drives the pusher to make a vertical linear motion, smoothly pushing the stator onto the intermediate platform. This flush transition avoids problems caused by height differences, prevents the stator from jumping or getting stuck when conveyed from the roller to the intermediate platform, and reduces the risk of impact damage (such as surface dents).

[0036] See Figure 2 As shown, the receiving seat 4 is located within the opening 31 of the intermediate platform 3, and it can move up and down relative to the opening 31 via a lifting component 5. The receiving seat 4 is used to receive stator products pushed out from the roller conveyor 2. The clamping component 6 is located above the intermediate platform 3, and the clamping component 6 can also move laterally relative to the intermediate platform 3 via a linear displacement module 7. The linear displacement module 7 is connected to the frame 1. That is to say, the receiving seat 4 moves upward under the drive of the lifting component 5, extending the stator product on it into the clamping component 6, so that the clamping component 6 can clamp the stator product. Then, the linear displacement module 7 drives the clamping component 6 to transfer the stator product to the next station.

[0037] See Figure 3 As shown, the clamping assembly 6 includes a support frame 61 and a bidirectional cylinder 62 mounted on the support frame 61. The support frame 61 is in a horizontal position. The bidirectional cylinder 62 is mounted on the bottom end face of the support frame 61. A displacement plate 63 is mounted at each end of the bidirectional cylinder 62. The two displacement plates 63 are distributed in parallel and spaced apart. The bidirectional cylinder 62 drives the two displacement plates 63 to move closer to each other or further away from each other. A pair of mirror-symmetrical vertical clamps 64 are mounted on the inner side of the displacement plates 63.

[0038] The bidirectional cylinder simultaneously drives two displacement plates to move towards the center or both sides, causing the vertical clamping body to mirror-grip or release the stator. The mirror symmetry design ensures balanced clamping force (if the cylinder air pressure is adjustable, it is suitable for stators of different sizes), avoiding stator deformation or tilting caused by unilateral force application; the vertical clamping body clamps the stator from the side, matching the cylindrical or ring structure of the motor stator, avoiding slippage caused by top or bottom force application, and the clamping point is close to the stator's center of gravity, ensuring smooth transfer and reducing the risk of shaking or falling off.

[0039] In addition, each vertical clamp 64 is provided with a limiting stop 65 at its bottom. The limiting stop forms a "bottom support" structure when clamped. When the vertical clamp clamps the stator side wall, the stop blocks the bottom of the stator from below, preventing it from falling or slipping under the action of gravity. This is especially suitable for heavier or smooth-surfaced stators, providing double protection. The stop restricts the vertical displacement of the stator, avoiding shaking caused by vibration or acceleration during transportation, and ensuring that the stator is in a fixed position. This reduces the risk of collision with surrounding components and protects the stator edges (such as the winding ends).

[0040] See Figure 2 As shown, a pair of protruding guide flanges 32 are provided on the top surface of the intermediate platform 3. The guide flanges 32 are distributed on both sides of the opening 31, forming a guide channel on both sides of the opening. When the stator is pushed out from the roller conveyor to the intermediate platform, the flanges constrain the direction of movement of the stator, preventing it from deviating or running out of the platform area. This ensures that the stator falls accurately into the receiving seat.

[0041] Example 2

[0042] The design scheme of this embodiment is based on the technical solution of embodiment 1, specifically an improved design of the lifting component.

[0043] See Figure 4 As shown, the lifting assembly 5 includes: a bracket 51 connected to the frame 1; a lifting cylinder 52, which is vertically mounted on the bracket 51, and a horizontal mounting plate 53 is provided on its lifting end; an adjusting column 54, the top end of which is connected to the receiving seat 4, and the bottom end of which is rotatably mounted on the mounting plate 53 through a bearing 55, that is, the adjusting column 54 can rotate relative to the mounting plate 53; and a fine-tuning cylinder 56, one end of which is hinged to the top surface of the mounting plate 53, and the other output end of which is hinged to the bottom surface of the adjusting column 54.

[0044] The lifting cylinder provides the main lifting force, enabling the receiving seat to move up and down within the opening to accommodate stators of different heights or the needs of the next workstation (such as raising the stator to a height easily gripped by the clamping assembly).

[0045] The fine-tuning cylinder applies force through the hinge point, pushing or pulling the adjusting column to rotate around the bearing component, thereby fine-tuning the level and angle of the receiving seat, improving clamping efficiency, and ensuring the stability of the stator's posture during transport.

[0046] Among them, the top of the receiving seat 4 is a sleeve part 41 with a diameter that gradually decreases from top to bottom. The tapered design of the sleeve part provides a guiding function. When the stator is pushed out from the roller conveyor and falls into the receiving seat, the gradually decreasing diameter guides the stator to automatically center itself, avoiding the stator edge from colliding with or sliding off the surface of the receiving seat. Moreover, when the lifting assembly adjusts the height, the sleeve part plays a self-centering role, reducing the initial positioning requirements of the clamping assembly. The tapered surface is usually a smooth arc surface, reducing the hard impact when in contact with the stator.

[0047] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
