DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. The specific structures and functional details disclosed herein are only used to describe the exemplary embodiments of the present invention. However, the present invention can be embodied in many alternative forms, and it should not be understood that the present invention is limited to the embodiments set forth herein.

[0029] At present, there are many types of motor rotor cores with different specifications. They are mainly positioned manually with poor positioning accuracy. Assembly is mainly done by knocking and interference fit single-machine press-fitting. The cores are transported manually with uncontrolled angles, resulting in low work efficiency, which affects the assembly quality of the rotor assembly and affects the performance of the motor.

[0030] At present, the main shaft of the rotor is positioned manually, with poor positioning accuracy; the flat keys, steel rings and magnetic isolation plates on the rotor shaft are mainly assembled by manual tapping. The assembly flexibility is low, the assembly quality cannot be guaranteed, the displacement and pressure curves during the assembly process cannot be monitored, and the assembly quality cannot be effectively guaranteed.

[0031] Figure 1 A schematic diagram of the structure of a core lamination device is provided for an embodiment of the present application. Figure 2 A partial enlarged schematic diagram of the first track 501 is provided for the embodiment of the present application. Figure 3 A partial enlarged schematic diagram of the positioning support 201 is provided for the embodiment of the present application. Figure 4 A partial enlarged schematic diagram of the clamping member 300 is provided for the embodiment of the present application.

[0032] like Figure 1 As shown, a core lamination device, in some embodiments, the core lamination device includes an operating frame 100, a positioning support 201, a supporting support 202, a clamping member 300 and a lamination member 400, wherein:

[0033] The operating frame 100 is set on the working platform and serves as a processing positioning tool in the processing area. It is arranged accordingly according to the relevant working equipment, so that the upper and lower disassembly and assembly of the iron core 702 and the rotor shaft 701 before and after processing can be more convenient and accurate. Specifically, the iron core 702 and the rotor shaft 701 can be installed to the target position by a robotic arm before assembly, and after the assembly operation of the iron core stacking device, they can be fixedly grasped to the work position of the subsequent operation by the corresponding robotic arm again, which is convenient for continuous processing operations.

[0034] The positioning support 201 and the supporting support 202 are respectively arranged on the operating frame 100 . The positioning support 201 is used to install the rotor shaft 701 , and the supporting support 202 is used to install the iron core 702 .

[0035] The clamping member 300 is movably arranged on the operating frame 100. The clamping member 300 is used to clamp the iron core 702 at the supporting bracket 202 and release the iron core 702 at the positioning bracket 201. The clamping member 300 is movably connected to the operating frame 100, the iron core 702 is installed on the supporting bracket, and the rotor shaft 701 is installed on the positioning bracket 201. At this time, the iron core 702 at different positions is grasped and moved to the rotor shaft 701 through the movable displacement of the clamping member 300, and no manual intervention is required for operations such as picking up. The grasping and releasing actions of the clamping member 300 during the displacement process maintain the stability of the iron core 702 before and after movement, so that the iron core 702 can be reliably arranged on the rotor shaft 701 on the positioning bracket 201.

[0036] The stacking part 400 is arranged on the operating frame 100, and the output end of the stacking part 400 can be longitudinally close to or away from the positioning support 201, and when the clamping part 300 moves to the positioning support 201, the stacking part 400 is used to press down the clamping part 300. After the clamping part 300 moves the iron core 702 to the rotor shaft 701, the stacking part 400 works and drives the clamping part 300 to descend as a whole. With the downward pressure of the clamping part 300, the iron core 702 is pressed and displaced toward the rotor shaft 701 until the relative position between the iron core 702 and the rotor shaft 701 meets the set state, and the stacking operation between the iron core 702 and the rotor shaft 701 is completed.

[0037] In some embodiments, the working principle of the core stacking device is as follows: by setting a positioning support 201 and a supporting support 202 on the operating frame 100, the positioning support 201 is used to install the rotor shaft 701, and the supporting support 202 is used to install the iron core 702, the clamping member 300 is movably arranged on the operating frame 100, the clamping member 300 is used to clamp the iron core 702 at the supporting support 202, and release the iron core 702 at the positioning support 201, the stacking member 400 is arranged on the operating frame 100, and the output end of the stacking member 400 can be close to or away from the positioning support 201 along the axial direction of the rotor shaft 701, and when the clamping member 300 moves to the positioning support 201, the stacking member 400 is used to press the clamping member 300 downward, and in actual operation, the iron core 70 2 is placed on the supporting support 202, the rotor shaft 701 is placed on the positioning support 201, the iron core 702 is clamped on the supporting support 202 by the movable clamping member 300, and the iron core 702 is moved to the rotor shaft 701 on the positioning support 201 for release, and then the laminating member 400 on the operating frame 100 is used to perform the laminating operation of the iron core 702. When the output end of the laminating member 400 is close to the positioning support 201, the iron core 702 is laminated on the rotor shaft 701 as required until the assembly requirements are met. This process does not require manual operation and alignment, thereby improving the positioning accuracy and laminating accuracy, and the operation process is less affected by manual operation, thereby effectively controlling the press-fitting quality during the operation process, and improving the automation degree of the entire operation process.

[0038] like Figure 1 , Figure 2 As shown, further, in some embodiments, the operating frame 100 is provided with a first track 501, one end of the first track 501 extends to under the clamping member 300, the supporting support 202 is movably provided on the first track 501, and the first track 501 is provided with a first driving mechanism 502 for driving the supporting support 202 to move along the extension direction of the first track 501.

[0039] Specifically, the first track 501 is arranged on the operating frame 100, and the supporting support 202 can move along the extension direction of the first track 501. Through the arrangement of the first track 501, the arrangement position of the supporting support 202 can be stably connected to two working positions. The end of the first track 501 away from the operating frame 100 can be more flexibly arranged to the placement position of the iron core 702, and then the iron core 702 can be moved from the placement position to the position where it can be clamped by the clamping member 300 during the movement of the supporting support 202 on the first track 501, thereby maintaining reliable operation. The first track 501 can be flexibly arranged according to the working environment, making the greatest use of the working environment and coordinating the connection status of different equipment in different processes.

[0040] like Figure 1 , Figure 3 As shown, further, in some embodiments, a second track 503 is provided on the operating frame 100, one end of the second track 503 extends to under the stacking member 400, the positioning support 201 is movably provided on the second track 503, and a second driving mechanism 504 is provided on the second track 503 for driving the positioning support 201 to move along the extension direction of the second track 503.

[0041] Specifically, the second track 503 is arranged on the operating frame 100, and the positioning support 201 can move along the extension direction of the second track 503. Through the arrangement of the second track 503, the arrangement position of the positioning support 201 can be stably connected to the two working positions, and the end of the second track 503 away from the operating frame 100 can be more flexibly arranged to the placement position of the rotor shaft 701, and then the rotor shaft 701 can be moved from the placement position to the position corresponding to the laminated part 400 during the movement of the positioning support 201 on the second track 503, that is, the rotor shaft 701 follows the positioning support 201. 01After moving to the target position on the second track 503, the iron core 702 on the clamping part 300 can be sleeved on the rotor shaft 701 during the process of the stacking part 400 pressing down the clamping part 300, and after the iron core 702 and the rotor shaft 701 complete the stacking operation, they are moved again on the second track 503 through the positioning support 201 until they move to the target position and can be taken away for subsequent operations, thereby maintaining reliable operation. The second track 503 can be flexibly arranged according to the working environment, making the greatest use of the working environment and coordinating the connection status of different equipment in different processes.

[0042] Furthermore, in some embodiments, the supporting bracket is provided with a first detecting portion 601 for detecting the iron core 702 , a third driving member 602 for driving the iron core 702 to rotate, and a control portion for connecting and controlling the first detecting portion 601 and the third driving member 602 .

[0043] The first detection part 601 is used to detect whether the iron core 702 is placed on the supporting bracket, and drives the iron core 702 to rotate through the third driving member 602. At the same time, the first detection part 601 identifies the rotation angle of the iron core 702. The control part receives the signal of the first detection part 601, and after processing, controls the third driving member 602 to work and rotate the iron core 702 to a set angle, so that after the clamping member 300 clamps the iron core 702, the iron core 702 can be positioned and assembled with the rotor shaft 701, thereby completing the preliminary positioning.

[0044] The first detection unit can be a laser sensor or a machine vision recognition device, and the specific type is not limited in this application.

[0045] Furthermore, in some embodiments, a second detection unit 603 for detecting the rotor shaft 701 and a control unit for connecting and controlling the second detection unit 603 and the laminated part 400 are provided on one side of the positioning bracket.

[0046] The second detection unit 603 is arranged on one side of the positioning bracket. After the rotor shaft 701 is placed, the rotor shaft 701 can be identified by the second detection unit 603, and the identified signal is processed by the control unit. The control unit then controls the subsequent operation steps to avoid continuing the stacking operation after the rotor shaft 701 is not stably installed. Specifically, after processing the detection signal of the second detection unit 603, the control unit can control the stacking part 400.

[0047] like Figure 4 As shown, further, in some embodiments, the clamping member 300 includes two clamping blocks 302 that can be moved closer or farther away at the same time, so as to clamp the iron core 702.

[0048] The two clamping blocks 302 on the clamping member 300 are controlled to move closer or further away to clamp and release the iron core 702. Specifically, the clamping blocks 302 can be driven synchronously by a screw rod, or can be pushed and pulled by a push cylinder to achieve displacement operation. The specific driving method will not be further expanded or limited.

[0049] Furthermore, in some embodiments, a third track 604 is provided on the operating frame 100 , and the clamping member 300 is provided on the third track 604 . Under the guidance of the third track 604 , the clamping member 300 can reciprocate above the positioning support 201 and the supporting support 202 .

[0050] The third rail 604 is arranged between the operating frame 100 and the clamping member 300. Through the third rail 604, the clamping member 300 can be moved in the extension direction of the third rail 604. Specifically, under the guidance of the third rail 604, the clamping member 300 can reciprocate above the positioning support 201 and the supporting support 202, and then reciprocate above the supporting support 202 and above the positioning support 201. The clamping member 300 can maintain a stable and precise moving stroke through the third rail 604, thereby improving the accuracy of the operation.

[0051] Furthermore, in some embodiments, a fourth track 605 is provided between the third track 604 and the clamping member 300 , and under the guidance of the fourth track 605 , the clamping member 300 can move closer to or away from the positioning support 201 or the supporting support 202 .

[0052] The third track 604 guides the clamping member 300 to reciprocate above the supporting support 202 and the positioning support 201. By setting the fourth track 605 between the third track 604 and the clamping member 300, the clamping member 300 is further guided to move closer to or away from the positioning support 201 or the supporting support 202 under the premise of the aforementioned movement. In conjunction with the change in the positional relationship with the supporting support 202, the iron core 702 can be stably grasped from the supporting support 202. In conjunction with the change in the positional relationship with the positioning support 201, the iron core 702 can be stably lowered above the rotor shaft 701 on the positioning support 201.

[0053] Furthermore, in some embodiments, a circumvention hole 301 for circumventing the rotor shaft 701 is provided in the middle of the clamp 300 .

[0054] When the clamping member 300 is driven by the stacking member 400 to descend as a whole, the iron core 702 descends synchronously, and the rotor shaft 701 does not move. In order to provide a reliable descending space for the iron core 702, the avoidance hole 301 provides the space required for the relative displacement of the rotor shaft 701, and keeps the clamping member 300 and the rotor shaft 701 from having structural interference, thereby improving the operation reliability. During the stacking operation of the iron core 702, a greater margin can be provided for the degree of stacking operation, which is convenient for controlling the operation. Even if the iron core 702 moves downward excessively during the stacking operation, no structural interference will occur.

[0055] Furthermore, in some embodiments, two of the supporting base 202 and two of the clamping member 300 are provided respectively.

[0056] The two supporting supports 202 place the iron core 702 in sequence according to the production rhythm, and operate the clamping members 300 respectively to clamp the iron core 702 on the two supporting supports 202 respectively, so as to improve the working efficiency through a more compact production rhythm. Correspondingly, two groups of clamping members 300 can also be set up to further optimize the production rhythm and improve efficiency.
