Description

Technical Field

[0001] This utility model relates to the field of mechanical automation and assembly technology, and in particular to a rapid feeding mechanism for motor shafts. Background Technology

[0002] In the manufacturing and assembly of motors, the efficiency and accuracy of motor shaft loading have a significant impact on the overall production cycle and product quality. Traditional motor shaft loading mainly relies on manual operation or simple semi-automatic devices, which often suffers from high labor intensity, high operational errors, and poor cycle consistency. In addition, in batch loading, the stacking and handling of material trays lacks coordinated control, which can easily cause jamming, material dropping, or positional deviations, affecting subsequent automated operations.

[0003] To address these issues, relevant technical solutions have gradually introduced automated units such as multi-station collaboration, suction cup handling, and lifting mechanisms, improving the automation level of certain processes. However, existing automated feeding systems often lack a unified and coordinated logic and structural layout. The loading and unloading of material trays and the tray loading process of motor shafts still rely heavily on manual intervention, making it difficult to achieve continuity and synchronization throughout the entire process, thus affecting further improvements in production efficiency and automation.

[0055] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0056] Example 1, referring to Figures 1 to 2 This is the first embodiment of the present invention, which provides a rapid feeding mechanism for motor shafts, enabling efficient and continuous automatic tray loading of motor shafts, significantly improving the automation level and assembly accuracy of the feeding operation, including:

[0057] The system includes a feeding support platform 1, a pushing component 2, a first lifting drive assembly 5, a transport drive assembly 7, a second lifting drive assembly 10, a feeding and transport assembly 9, a pulling component 12, and various supporting workstations, specifically including a pushing workstation A, a first lifting workstation C, a transport workstation E, a second lifting workstation D, a feeding workstation F, and a pulling workstation B.

[0058] The pushing component 2 is located at the pushing station A, and its drive output end is fixedly connected to the first placement bracket 3 for stacking multiple empty material trays 4. The pushing component 2 is used to drive the first placement bracket 3 to move along the X-axis direction, pushing the empty material trays 4 to the first lifting station C.

[0059] The first lifting drive assembly 5 is installed on the side of the first lifting station C. The drive output end is connected to the first lifting bracket 6. The first lifting bracket 6 is located at the bottom of the empty material trays 4 stack and is used to realize the layer-by-layer lifting of the empty material trays 4. Each time the material tray 4 is lifted, it is convenient for the top material tray 4 to be moved later.

[0060] The transport drive unit 7 is located at the transport station E, and its drive output end is connected to the suction cup assembly 8. The transport station E is located above the first and second lifting stations D. The transport drive unit 7 drives the suction cup assembly 8 to pick up the top empty material tray 4 of the first lifting station C and transport it to the top of the stacked material tray 4 of the second lifting station D.

[0061] The second lifting drive assembly 10 is installed on the side of the second lifting station D, and its output end is connected to the second lifting bracket 11, located at the bottom of the stacking tray 4. This assembly is used to lower the tray 4 by one tray thickness after each motor shaft is placed, realizing multiple tray loading and layer-by-layer lowering.

[0062] The loading and conveying assembly 9 is located between the second lifting station D and the loading station F, and includes a horizontal conveying component 91 and a lifting and conveying component 92. The output end of the lifting and conveying component 92 is provided with a clamping component 93, which is used to clamp the motor shaft of the external feeding position and accurately place the motor shaft in the preset slot on the material tray 4 under the control of the X-axis and Z-axis directions.

[0063] The pulling component 12 is installed at the pulling station B, and its drive output end is connected to the second placement bracket 13. When the second lifting station D descends to the lowest point, the entire stack of material trays 4 filled with motor shafts is transferred to the second placement bracket 13, and then moved by the pulling component 12 along the X-axis to the pulling station B, realizing the centralized collection and transfer of the finished material trays 4.

[0064] Working principle of Example 1: The operation process of this rapid feeding mechanism is as follows:

[0065] Empty material tray 4 supply: Multiple empty material trays 4 are pre-stacked on the first placement bracket 3 and pushed to the first lifting station C by the pushing component 2;

[0066] Layer by layer: The first lifting drive component 5 drives the first placement bracket 3 to rise layer by layer, so that the empty material trays 4 are in the handling position one by one;

[0067] Material tray 4 handling: The suction cup assembly 8 picks up the top empty material tray 4 and transports it to the second lifting station D for stacking;

[0068] Motor shaft mounting: The loading and conveying assembly 9 clamps the motor shaft and places it in the preset slot of the material tray 4 of the second lifting station D;

[0069] Automatic descent: The second lifting drive component 10 controls the material trays 4 to descend layer by layer, completing multiple tray loading operations;

[0070] Finished product output: The material trays 4 filled with motor shafts are stacked and then transferred by the pulling component 12 to the pulling station B for collection or subsequent processing.

[0071] Technical effects of Example 1:

[0072] 1. Automatic feeding, handling and positioning of material tray 4 are realized, improving material feeding efficiency;

[0073] 2. The motor shaft mounting process is fully automated, reducing manual operation and improving consistency and assembly accuracy;

[0074] 3. Maximizes space utilization and features a compact structure by utilizing lifting and stacking technology;

[0075] 4. The push and pull mechanism operates in a closed loop to achieve rapid circulation and inbound / outbound management of the material tray 4;

[0076] 5. The modular design facilitates maintenance and expansion, and is compatible with different specifications of material trays and motor shafts.

[0077] Example 2 is the second embodiment of this utility model. Unlike the previous embodiment, based on Example 1, in order to further improve the lifting accuracy and structural stability, the specific structure of the first lifting drive component 5 and the second lifting drive component 10 has been optimized in this embodiment.

[0078] Reference Figure 3 The first lifting drive assembly 5 and the second lifting drive assembly 10 both include the following structural units:

[0079] Lifting base plate 51: Vertically fixed on the side of the loading support platform 1, serving as the installation base for the entire lifting drive system;

[0080] Drive motor 52: fixed to the bottom of the lifting base plate 51, with its output shaft pointing vertically upward;

[0081] Lead screw 53: It is coaxially connected to the output shaft of drive motor 52 via a coupling. The rotation of drive motor 52 drives lead screw 53 to rotate.

[0082] Lifting slider 54: It is threaded onto lead screw 53. When lead screw 53 rotates, it drives lifting slider 54 to move along the Z-axis.

[0083] Lifting vertical plate 55: Fixedly connected to the side of the lifting slider 54 away from the lifting base plate 51, used to transmit lifting power;

[0084] Lifting slide rail 56 and slide rail slider 57: Two guide slide rails 23 along the Z-axis are provided on the lifting base plate 51. Slide rail sliders 57 matching the slide rails are fixed on both sides of the lifting vertical plate 55. The sliders are slidably sleeved on the slide rails to suppress lateral swaying during the lifting process and improve the smoothness of operation.

[0085] The first lifting bracket 6 and the second lifting bracket 11 are respectively fixed on the lifting vertical plates 55 corresponding to the first and second lifting drive components 10.

[0086] To ensure the lifting support smoothly passes through the material tray 4-bracket structure and achieves complete vertical travel, refer to... Figure 4 The first placement bracket 3 and the second placement bracket 13 are respectively provided with a first lifting opening 31 and a second lifting opening 131 in the middle part. Their outline dimensions are larger than the cross-sectional dimensions of the corresponding lifting bracket, ensuring that the lifting bracket can move through along the Z-axis without obstruction.

[0087] Working principle of Example 2:

[0088] When multiple empty material trays 4 are pushed to the first lifting station C, the first lifting drive motor 52 starts, drives the lead screw 53 to rotate, and then causes the threaded lifting slider 54 to move upward along the lead screw 53, which in turn lifts the lifting vertical plate 55 and the first lifting bracket 6.

[0089] The first lifting bracket 6 lifts the stacked empty material trays 4 from bottom to top, achieving layer-by-layer lifting, lifting the height of one material tray 4 each time, ensuring that the top material tray 4 is located in the transport position;

[0090] Similarly, the material trays 4 filled with motor shafts are stacked at the second lifting station D. The second lifting drive assembly 10 drives the stacked material trays 4 to descend layer by layer through the same structure, descending by the height of one material tray 4 each time, providing a stable platform for the next loading.

[0091] The entire lifting process maintains the smoothness and anti-deviation capability of the lifting motion through the dual guide rails 23 and the slider system, which improves the stability and loading accuracy of long-term operation.

[0092] The lifting support can pass through the lifting opening in the middle of the support in the material tray 4, avoiding interference with the support structure during lifting, ensuring a smooth vertical path and improving structural compactness.

[0093] Technical effects of Example 2:

[0094] 1. High lifting accuracy: The screw 53-slider structure is used for driving, and the guide rail 23 is used to effectively reduce lifting deviation and ensure the consistency of the material tray 4 positioning each time.

[0095] 2. Stable and reliable operation: The lifting slider 54 is linked with the guide rail slider to avoid swaying and jamming, which is suitable for high-frequency automatic tray loading scenarios.

[0096] 3. Optimized structure and compact layout: The lifting support is arranged with an open structure nested arrangement, which saves space and makes the overall equipment structure more compact;

[0097] 4. Strong versatility and compatibility: The lifting components are modularly designed, making them easy to replace, maintain or upgrade, and can be adapted to different specifications of trays and process requirements.

[0098] 5. Improved tray loading accuracy and efficiency: When operating in conjunction with Example 1, it achieves precision, efficiency and stability in the automated tray loading process of the motor shaft.

[0099] Example 3 is the third embodiment of this utility model. Unlike the previous embodiment, in order to further improve the automation level of the whole machine, the action response speed and the stability of module operation, this embodiment focuses on optimizing the structural configuration of the pushing component 2, the pulling component 12, the conveying drive component 7 and the feeding and conveying assembly 9 based on Examples 1 and 2.

[0100] I. Structure of Pushing Component 2 and Pulling Component 12
