Description

Technical Field

[0001] This invention relates to the field of rotor feeding technology, and more specifically to a motor rotor feeding device. Background Technology

[0002] The working principle of the motor rotor unloading device needs to be combined with its specific structure and type. Electronic rotor unloading is divided into three types: robotic arm type, conveyor belt type, and pneumatic type. Among them, in the conveyor belt type unloading equipment, the continuous movement of the conveyor belt, roller or chain is mainly used to transport the processed rotor from the end of the station to the next stage. It is suitable for the rapid transfer of large batches of regular-shaped rotors. However, there are still areas that need improvement when unloading.

[0003] For example, in actual operation, due to the different thicknesses, mechanical properties and sizes of silicon steel sheets from different batches, mismatches may easily occur when cutting materials from the same batch. For example, some rotors may be too long, and when transported to the next position, they may be restricted by the limited width of the conveyor belt, which may cause some inconvenience. In order to improve work efficiency, Summary of the Invention

[0017] Furthermore, the pusher also includes:

[0052] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the invention and to fully convey the scope of the invention to those skilled in the art.

[0053] like Figures 1 to 7 As shown, a motor rotor unloading device includes a workbench 1 and a limiting plate 2 fixedly installed above it. A central shaft 3 is rotatably arranged inside the limiting plate 2, and a transmission belt 4 is rotatably arranged outside the central shaft 3. A baffle 6 is fixedly installed on one side of the workbench 1. The device is characterized by further including: a receiving member 5 is provided on the inner wall of the workbench 1 and the receiving member 5 is located below the workbench 1; a mounting seat 7 is provided above the limiting plate 2; and an assembly table 8 is provided on the outer side of the limiting plate 2.

[0054] The unloading section is located inside the limiting plate 2 and above the assembly table 8 to unload the motor rotor workpiece;

[0055] The unloading part includes an upper pusher, a horizontal pusher, and an adjusting member. The upper pusher is located above the assembly table 8, the horizontal pusher is located on the inner wall of the mounting base 7, the horizontal pusher and the upper pusher are connected, and the adjusting member is located on the inner side of the worktable 1.

[0056] The leveling assembly is located inside the workbench 1 to receive the motor rotor workpiece.

[0057] During operation, the motor rotor workpiece to be unloaded is first placed above the transmission belt 4. The central shaft 3 is started to drive the transmission belt 4 to rotate, so that the motor rotor workpiece is transferred to the next process to complete the unloading. It should be noted that the motor rotor workpiece is a finished product.

[0058] During the conveying process, the motor rotor workpiece moves horizontally above the transmission belt 4. The horizontal pusher senses the position change of the motor rotor workpiece. When the motor rotor workpiece passes the position of the horizontal pusher, the horizontal pusher starts to work. The horizontal pusher gradually squeezes from both sides to the middle, straightening the motor rotor workpiece in the middle, preventing the motor rotor workpieces of different specifications from tilting during the transmission process, and avoiding collisions or damage.

[0059] When placing multiple motor rotor workpieces, if the distance between two adjacent motor rotor workpieces is too close, one may tilt, causing the other motor rotor workpieces to tilt simultaneously, which is detrimental to improving the pass rate. When it is necessary to adjust the distance between adjacent motor rotor workpieces, the pusher is activated, and the force of the drive source is used to move it to a position flush with the motor rotor workpiece and lock it in place. Then, the distance between the adjacent motor rotor workpieces is increased to prevent them from being affected by linkage or piling up, thus improving the efficiency of the transmission process. In addition, the pusher will twist in conjunction with the adjustment component to relieve the force on the motor rotor workpiece, thereby facilitating subsequent disassembly and use.

[0060] When conveying the motor rotor workpiece to the next process, if there is a gap between the next process and the docking position of the transmission belt 4, the motor rotor workpiece can easily fall off from the docking point between the next process, causing inconvenience in collection. Therefore, the leveling component is driven to move to one end of the transmission belt 4, at which point the motor rotor workpiece is picked up, and then the motor rotor workpiece is pulled back to the initial position by retracting, so as to facilitate secondary transmission or recycling.

[0061] like Figure 2 , Figure 7 The push-up component includes:

[0062] There are two controllers 80, which are symmetrically fixed above the assembly table 8;

[0063] The first electric lever 81 is rotatably mounted on one side of the controller 80.

[0064] The torsion block 82 is located on the outside of the first electric lever 81;

[0065] The gripper bar 83 is fixedly installed on the outside of the torsion block 82;

[0066] A position sensor is installed below the torsion block 82.

[0067] The telescopic base 85 is fixedly installed on the outside of the controller 80;

[0068] The elastic connecting plate 84 is set between the telescopic seat 85 and the grab bar 83.

[0069] During operation, when multiple motor rotor workpieces are transported on the transmission belt 4, sometimes the distance between two adjacent motor rotor workpieces becomes too close due to the high transmission speed of the transmission belt 4 or manual placement. This can easily cause one motor rotor workpiece to skew, and the other motor rotor workpieces will be affected by the linkage and skew synchronously. Readjustment is time-consuming and relatively inconvenient. In this embodiment of the invention, the position sensor senses the change in the distance between two adjacent motor rotor workpieces and feeds back the electrical signal to the controller 80. The controller 80 drives the first electric rod 81 to extend, which moves the torsion block 82 above the two adjacent motor rotor workpieces. The torsion block 82 drives the gripping bar 83 and the elastic connecting plate 84 to move synchronously. The elastic connecting plate 84 is pulled out from inside the telescopic seat 85, and the gripping bar 83 will lock onto the top of one of the motor rotor workpieces. At this time, with the extension of the torsion block 82 and the gripping bar 83, the distance between the adjacent motor rotor workpieces is adjusted to a suitable spacing, thus providing a function to facilitate spacing adjustment and preventing the situation of being affected by linkage and piling up due to overly dense placement.

[0070] like Figure 3 , Figure 4 As shown, the transverse pusher includes:

[0071] Two inclined plates 71 are provided and are symmetrically arranged above the mounting base 7.

[0072] The electric telescopic component 72 is installed on the inner side of the inclined plate 71.

[0073] The thin plate 73 is telescopically connected inside the electrically telescopic component 72;

[0074] The inclined plate 71 is connected to the electric telescopic component 72, and a rotating shaft is provided between the inclined plate 71 and the mounting base 7, with one end of the rotating shaft connected to the servo motor drive end.

[0075] During operation, due to the inconsistent thickness, mechanical properties, and size of silicon steel sheets from different batches, mismatches can easily occur when cutting materials from the same batch. For example, during transmission, some motors may tilt due to being too light or too heavy, requiring straightening treatment. Using the preferred embodiment of the present invention, when the motor rotor workpiece conveyed above the transmission belt 4 moves to a position with a suitable spacing, the electric telescopic component 72 is driven to work. The electric telescopic component 72 gradually moves the thin plate 73 forward. As the thin plate 73 extends, it gradually contacts the motor rotor workpiece. The two thin plates 73 move from both sides to the middle position of the motor rotor workpiece, forming a tendency to clamp the motor rotor workpiece, thereby achieving the effect of straightening it and preventing the thin plate 73 from shaking or shifting in position and causing damage.

[0076] When the motor rotor workpiece is supported, since the thin plate 73 is set to be inclined upwards by default, the support position may be inaccurate after the thin plate 73 is extended. Therefore, the servo motor is driven to rotate. The servo motor drives the rotating shaft to rotate only twenty degrees and then stops. Before the rotating shaft moves in conjunction with the inclined plate 71, the direction of the electric telescopic component 72 is adjusted to a suitable straightening angle to ensure the accuracy of straightening. It should be noted that the servo motor rotation of twenty degrees is a pre-set programmed execution command.

[0077] like Figure 5 As shown, the adjusting component includes:

[0078] The base 50 has two parts, which are slidably connected to the inner wall of the receiving part 5, and a slider that can cooperate with the inner wall of the receiving part 5 is provided below it;

[0079] The second electric rod 51 is located on one side of the base 50 and extends through the base 50;

[0080] Mounting plate 52 is fixedly installed on one side of the second electric pole 51;

[0081] Auxiliary plates 53 are symmetrically fixed to the outside of mounting plates 52;

[0082] The auxiliary plate 53 has multiple evenly distributed recessed holes along its upper edge;

[0083] One end of the second electric pole 51 is equipped with a direct drive motor, and the drive end of the direct drive motor is connected to the second electric pole 51.

[0084] During operation, when receiving the motor rotor workpiece, using the preferred embodiment of the present invention, the second electric rod 51 is energized and gradually extends. The second electric rod 51 pushes the mounting plate 52 to move to the other side of the transmission belt 4. The base 50 slides on the inner wall of the receiving member 5. The mounting plate 52 is linked to the displacement of the auxiliary plate 53. The auxiliary plate 53 moves to below the baffle 6. At this time, the motor rotor workpiece that falls below the baffle 6 is received in the recessed hole on the auxiliary plate 53 and slides down from top to bottom through the recessed hole of the auxiliary plate 53, thereby enabling the equipment to achieve the purpose of recycling. It should be noted that the second electric rod 51, the electric telescopic member 72, and the first electric rod 81 in the circuit are all electrically connected, which is an execution command set by the programming program.

[0085] like Figure 6 As shown, the leveling components include:

[0086] Connector plate 803 is located on one side of controller 80;

[0087] Linkage seat 802 is fixedly installed below the connecting plate 803 and can be matched with inclined plate 71;

[0088] The extrusion shaft 801 is located below the linkage seat 802.

[0089] Connector plate 803 is connected to controller 80;

[0090] The clamping plate 804 is located below the extrusion shaft 801.

[0091] During operation, the servo motor is driven to rotate, causing the rotating shaft to twist by twenty degrees. This rotation, in conjunction with the inclined plate 71, aligns the shaft. When the inclined plate 71 is aligned, it activates the linkage seat 802, which moves synchronously with the twenty-degree counter-clockwise rotation of the inclined plate 71. The linkage seat 802 then moves in conjunction with the pressing shaft 801 and the clamping plate 804. The clamping plate 804 gradually contacts and blocks the gap between the inclined plate 71 and the mounting base 7, preventing the inclined plate 71 from twisting further and ensuring stable positioning of the equipment. It should be noted that a gap, matching the thickness of the clamping plate 804, is provided between the inclined plate 71 and the mounting base 7.

[0092] Furthermore, when the gripper bar 83 separates adjacent motor rotor workpieces by clamping them, sometimes the gripper bar 83 happens to fit the motor rotor workpiece of the appropriate size, resulting in an overly tight clamping position. This makes it difficult to release the gripper bar and can cause transmission problems. When the linkage seat 802 is linked by the inclined plate 71, the connecting plate 803 moves synchronously with the linkage seat 802. The twisting tendency of the connecting plate 803 compresses the torsion block 82, causing the angle of the torsion block 82 to be twisted. This facilitates faster separation of the gripper bar 83 from the position clamped on the motor rotor workpiece, improving separation efficiency and achieving rapid operation, thus avoiding the problem of the gripper bar 83 clamping the motor rotor workpiece too tightly. It should be noted that the connecting plate 803 is installed on one side of the assembly table 8.

[0093] The motor rotor unloading device mainly consists of a worktable 1, a limiting plate 2, a central shaft 3, a transmission belt 4, and other basic structures, as well as an unloading section and a leveling assembly. Its working process is as follows:

[0094] The motor rotor workpiece is placed on the transmission belt 4, and the central shaft 3 drives the transmission belt 4 to rotate to achieve unloading and transmission. The horizontal pusher and the upward pusher of the unloading part work together to ensure stable transmission. The electric telescopic component 72 in the horizontal pusher drives the inclined plate 73 to clamp and straighten motor rotors of different specifications. The servo motor adjusts the angle of the inclined plate 71 through the rotating shaft to ensure accurate straightening. The position sensor of the upward pusher monitors the workpiece spacing, and the controller 80 controls the first electric rod 81 to drive the gripper bar 83 to adjust the spacing between adjacent workpieces. The elastic connecting plate 84 assists in the operation to prevent the workpieces from tilting or piling up. The second electric rod 51 of the adjusting component pushes the mounting plate 52 and the auxiliary plate 53 to move and receive the workpieces that fall from the baffle 6 for recycling. When the inclined plate 71 is straightened, the leveling component uses the linkage seat 802 to drive the extrusion shaft 801 and the clamping plate to fix the inclined plate 71 to prevent inaccurate positioning after rotation. At the same time, the connecting plate 803 is linked with the torsion block 82 to help the gripper bar 83 quickly separate the stuck workpieces. In addition, when there is a gap in the transmission docking, the leveling component can catch the workpiece and pull it back, which facilitates secondary transmission or recycling, ensuring efficient and stable operation of the motor rotor unloading in all aspects.
