Description

Technical Field

[0001] This utility model specifically relates to a reciprocating clamp sorting and conveying device for a rotor assembly machine. Background Technology

[0002] The ignition switch of existing motorcycles or electric vehicles connects and disconnects the circuit through a rotor. The rotor drives the moving contact to make contact with the external stationary contact. When the rotation causes the moving contact to make contact with the external stationary contact, it can activate the corresponding circuit system, so that the circuit system outputs power to connect with the vehicle and allows the vehicle to use electricity.

[0003] To meet the demands of high-volume and efficient rotor assembly, a corresponding rotor assembly machine needs to be designed. During rotor assembly, rotor clamps are required to hold the rotors. These clamps not only transport the rotors but also support them during the assembly of components such as springs, steel balls, and contact plates, ensuring the smooth completion of the rotor assembly process. Therefore, the rotor assembly machine must consider "how to efficiently and orderly transport the rotor clamps." Only in this way can efficient and accurate assembly be achieved during subsequent assembly operations within the rotor assembly machine. Utility Model Content

[0004] The technical problem to be solved by this utility model is to address the shortcomings of the prior art by providing a reciprocating fixture sorting and conveying device for a rotor assembly machine. This device enables continuous transfer of rotor fixtures between the upper and lower fixture sorting guide rails, avoiding the efficiency loss caused by waiting and reversing in traditional single-rail conveying. At the same time, the fixed guidance of the two fixture sorting guide rails and the precise pushing of the push cylinder ensure the orderly transport of rotor fixtures, thereby improving rotor assembly production efficiency and assembly accuracy.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reciprocating fixture sorting and conveying device for a rotor assembly machine, comprising a frame, characterized in that: an upper fixture sorting guide rail and a lower fixture sorting guide rail are fixedly installed on the frame and arranged parallel to each other; a first lifting and transferring component is provided at one end of the upper fixture sorting guide rail, and a second lifting and transferring component is provided at the other end of the upper fixture sorting guide rail; the first lifting and transferring component includes a liftable first transferring seat and a first pushing cylinder that pushes the product on the first transferring seat to the upper fixture sorting guide rail, the output end of the first pushing cylinder corresponding to the upper fixture sorting guide rail; the second lifting and transferring component includes a liftable second transferring seat and a second pushing cylinder that pushes the product on the second transferring seat to the lower fixture sorting guide rail, the second pushing cylinder corresponding to the lower fixture sorting guide rail.

[0006] Using the above technical solution, the upper and lower clamping sorting guide rails, arranged in parallel, form a cyclic conveying path. The first and second lifting and transferring components are located at opposite ends of the guide rails. When transporting the rotor clamp, the first transfer seat carries the rotor clamp upward to a position aligned with the upper clamping sorting guide rail. The first push cylinder is activated, pushing the rotor clamp from the first transfer seat into the upper clamping sorting guide rail. The rotor clamp moves along the upper guide rail towards the second lifting and transferring component. Simultaneously, the second transfer seat descends to a position aligned with the lower clamping sorting guide rail. The second push cylinder pushes the assembled or returnable rotor clamp from the lower clamping sorting guide rail into the second transfer seat. After the second transfer seat rises, subsequent actions (such as reversing or direct transfer) transfer the rotor clamp to the starting end of the lower clamping sorting guide rail, forming a reciprocating cycle of "upper guide rail forward conveying – lower guide rail reverse return," ultimately achieving efficient and orderly transport of the rotor clamp within the assembly machine. This solution enables continuous transfer of rotor fixtures between the upper and lower fixture sorting guides, avoiding efficiency losses caused by waiting and reversing in traditional monorail conveying. Simultaneously, the fixed guidance of the two fixture sorting guides and the precise pushing of the cylinders ensure the orderly transport of the rotor fixtures, providing a stable support foundation for the subsequent assembly of parts such as springs, steel balls, and contact plates. This fundamentally improves the overall production efficiency and assembly accuracy of the rotor assembly machine. Notably, this solution eliminates the need for continuously operating transmission components such as conveyor belts, and the number of rotor fixtures is fixed, requiring no manual intervention to increase or decrease. Furthermore, during rotor assembly, the rotor does not require manual disassembly or assembly.

[0007] The reciprocating clamp sorting and conveying device for the rotor assembly machine described above can be further configured as follows: the upper clamp sorting guide rail is provided with a first clamp conveying groove arranged along the axial direction of the upper clamp sorting guide rail, and the two ends of the first clamp conveying groove are open towards the first lifting and transferring component and the second lifting and transferring component, respectively; the lower clamp sorting guide rail is provided with a second clamp conveying groove arranged along the axial direction of the lower clamp sorting guide rail, and the two ends of the second clamp conveying groove are open towards the second lifting and transferring component, respectively; a plurality of sets of rotor clamps are evenly distributed in the first clamp conveying groove and the second clamp conveying groove, and each two adjacent sets of rotor clamps located in the first clamp conveying groove or the second clamp conveying groove abut against each other.

[0008] Using the above technical solution, the first and second clamping material conveying channels serve as axial guide channels, limiting the movement trajectory of the rotor clamps and preventing lateral displacement or overturning during transportation. This ensures that the rotor clamps are always aligned with the positioning reference of the subsequent assembly station. The mutual abutment of adjacent rotor clamps within the two clamping material conveying channels creates a "linked pushing" effect through mechanical contact—when the first rotor clamp is pushed, all subsequent rotor clamps transmit power sequentially through the abutment force. This eliminates the need for a separate drive device for each clamp, reducing costs while achieving a close arrangement of clamps and maximizing the use of guide rail space. Furthermore, this solution allows for rapid adjustment of the rotor clamp's "single movement distance" by simply adjusting the extension distance of the two push cylinders.

[0009] The reciprocating clamp sorting and conveying device for the rotor assembly machine described above can be further configured as follows: a first support surface is provided below the first clamp conveying trough on both sides of the first clamp conveying trough, and a first strip-shaped hollow groove is provided between the two sets of the first support surfaces; a second support surface is provided below the second clamp conveying trough on both sides of the second clamp conveying trough, and a second strip-shaped hollow groove is provided between the two sets of the second support surfaces.

[0010] By adopting the above technical solution, the first and second support surfaces serve as the bearing surfaces on both sides of the material conveying trough, providing symmetrical support for the rotor clamp. This prevents the rotor clamp from tilting or jamming due to unilateral force or center of gravity shift, ensuring the stability of the transportation process. Furthermore, the design of the first and second strip-shaped hollow slots reduces the contact area between the lower end of the rotor clamp and the clamp sorting guide rail, thereby reducing static friction and improving the smoothness of the rotor clamp's movement within each set of clamp material conveying troughs, preventing jamming.

[0011] The reciprocating fixture sorting and conveying device for the rotor assembly machine described above can be further configured as follows: the first transfer seat is linked to a fifth cylinder, the first transfer seat is linked to a fifth slider, the fifth slider is slidably engaged with a fifth slide rail, the fifth slide rail is fixed on the frame, and the fifth cylinder is used to drive the first transfer seat to reciprocate between the upper fixture sorting guide rail and the lower fixture sorting guide rail; the second transfer seat is linked to a sixth cylinder, the second transfer seat is linked to a sixth slider, the sixth slider is slidably engaged with a sixth slide rail, the sixth slide rail is fixed on the frame, and the sixth cylinder is used to drive the second transfer seat to reciprocate between the upper fixture sorting guide rail and the lower fixture sorting guide rail.

[0012] Using the above technical solution, after the first pushing cylinder pushes the rotor clamp from the first transfer seat into the first clamp conveying groove of the upper clamp sorting guide rail, the rotor clamp moves along the upper clamp sorting guide rail towards the second lifting and transferring assembly under the resistance force of the preceding rotor clamp. During this process, the second transfer seat is simultaneously driven by the sixth cylinder, sliding upward along the sixth slide rail via the sixth slider until it aligns with the opening of the first clamp conveying groove at the end of the upper clamp sorting guide rail. At this time, as the rotor clamps in the upper guide rail are continuously pushed, the last rotor clamp is pushed into the second transfer seat by the resistance force of the subsequent rotor clamp, completing the receiving action from the upper clamp sorting guide rail to the second transfer seat. Then, the first and second transfer seats move down synchronously to correspond to the second clamp conveying groove, and the second pushing cylinder pushes the rotor clamp in the second transfer seat into the second clamp conveying groove, where the first transfer seat catches the rotor clamp that is pushed out at the other end. Repeating the above actions ensures the reciprocating transport of the rotor clamp.

[0013] The reciprocating fixture sorting and conveying device for the rotor assembly machine described above can be further configured as follows: the first transfer seat includes a first transfer groove, both ends of the first transfer groove are open, a third support surface distributed on both sides of the first transfer groove is provided below the first transfer groove, and a third strip-shaped hollow groove is provided between the two sets of the third support surfaces; the second transfer seat has the same structure as the first transfer seat.

[0014] By adopting the above technical solution, the third support surface serves as the bearing surface on both sides of the transfer groove, providing symmetrical support for the rotor clamp. This prevents the rotor clamp from tilting or jamming due to unilateral force or center of gravity shift, ensuring the stability of the transportation process. By setting the third strip-shaped hollow groove, the contact area between the lower end of the rotor clamp and the two transfer seats is reduced, thereby reducing static friction and improving the smoothness of the rotor clamp's movement within each set of transfer grooves, preventing jamming.

[0015] The reciprocating clamp sorting and conveying device for the rotor assembly machine described above can be further configured as follows: the rotor clamp includes a clamping seat, and two sets of symmetrically arranged arc-shaped limiting blocks are provided above the clamping seat. There is a clamping gap between the two sets of arc-shaped limiting blocks that can accommodate the rotor. Inserts distributed between the two sets of arc-shaped limiting blocks are also provided above the clamping seat. An infeed inclined surface is provided above the arc-shaped limiting blocks. When the rotor is placed in the clamping gap, the inserts are inserted into the rotor.

[0016] Using the above technical solution, two sets of arc-shaped limiting blocks cooperate with the plug-in to clamp the rotor, preventing the rotor from deflecting during transportation and improving assembly accuracy. The inclined feed surface makes the rotor assembly into the rotor fixture smoother and less prone to interference.

[0017] The reciprocating clamp sorting and conveying device for the rotor assembly machine described above can be further configured as follows: the side of the first lifting and transfer component is provided with a rotor loading mechanism for orderly transporting the rotor. The rotor loading mechanism includes a first vibrating feeder, a first rotary cylinder distributed between the first vibrating feeder and the upper clamp sorting guide rail, and a first transfer mechanism for transferring the rotor from the first vibrating feeder to the first rotary cylinder and / or for transferring the rotor from the first rotary cylinder to the rotor clamp in the upper clamp sorting guide rail.

[0018] Using the above technical solution, the first vibrating feeder drives the rotor to initially sort and continuously convey along its conveying path through regular vibration. The first transfer mechanism transfers the rotor from the first vibrating feeder to the first rotary cylinder, which drives the rotor to rotate until it can be clamped into the rotor fixture. The adjusted rotor can then be transferred again by the first transfer mechanism to the rotor fixture on the upper fixture sorting guide rail. The rotor fixture moves with the reciprocating fixture sorting and conveying device into the subsequent process. The entire process, through the initial sorting by the first vibrating feeder, the directional adjustment by the first rotary cylinder, and the connection by the first transfer mechanism, achieves continuous and orderly feeding of the rotor.

[0019] The reciprocating clamp sorting and conveying device for the rotor assembly machine described above can be further configured as follows: a rotor sorting guide rail is installed above the first linear vibrating feeder, and a rotor conveying groove is provided on the rotor sorting guide rail along the axial direction of the rotor sorting guide rail. A positioning block is connected to the end of the rotor sorting guide rail facing the first rotary cylinder. The positioning block is provided with a rotor positioning groove. The rotor positioning groove has an opening on the side facing the rotor sorting guide rail and the rotor positioning groove communicates with the rotor conveying groove through the opening. A positioning seat is linked to the output end of the first rotary cylinder. A positioning structure is provided on the positioning seat. When the first transfer mechanism transfers the rotor from the rotor conveying groove to the positioning structure on the positioning seat, the first rotary cylinder drives the positioning seat to rotate, and then the positioning structure synchronously drives the rotor to rotate.

[0020] Using the above technical solution, when the first transfer mechanism transfers the rotor, which has been initially sorted by the rotor sorting guide rail, to the positioning structure of the positioning seat, the positioning structure can be configured as a positioning hole adapted to the bottom of the rotor or a protrusion inserted into the bottom of the rotor, so that the positioning structure and the rotor engage, fixing the rotor to the positioning seat. At this time, the output end of the first rotary cylinder drives the positioning seat to rotate synchronously. Due to the action of the positioning structure, the rotor rotates synchronously with the positioning seat until it can be clamped into the rotor fixture. Then the first rotary cylinder stops operating, and the first transfer mechanism transfers the rotor from the positioning seat to the rotor fixture again, entering the subsequent testing and final calibration process.

[0021] The reciprocating fixture sorting and conveying device for the rotor assembly machine described above can be further configured as follows: the first transfer mechanism includes a first main transfer plate and a first auxiliary transfer plate. One end of the first main transfer plate is linked to a first gripper cylinder for transferring the rotor from the rotor positioning slot to the positioning structure, and the other end of the first main transfer plate is linked to a second gripper cylinder for transferring the rotor from the positioning structure to the rotor fixture. The first main transfer plate is linked to a first cylinder for driving the first main transfer plate to reciprocate vertically. The body of the first cylinder is mounted on the first auxiliary transfer plate. The first main transfer plate is linked to a first slider, which is slidably engaged with a first slide rail mounted on the first auxiliary transfer plate. The first auxiliary transfer plate is linked to a second cylinder for driving the first auxiliary transfer plate to reciprocate horizontally. The body of the second cylinder is fixed to the frame. The first auxiliary transfer plate is linked to a second slider, which is slidably engaged with a second slide rail mounted on the frame.

[0022] Using the above technical solution, the second cylinder starts first, driving the first auxiliary transfer plate to move horizontally along the second slide rail until the first gripper cylinder on the first main transfer plate aligns with the positioning block (rotor positioning slot) at the end of the rotor sorting guide rail. Simultaneously, the second gripper cylinder on the first main transfer plate aligns with the positioning structure. Then, the first cylinder starts, pushing the first main transfer plate vertically downwards along the first slide rail. The grippers of the first gripper cylinder open and hold the rotor in the rotor positioning slot, while the grippers of the second gripper cylinder open and hold the rotor at the positioning structure. The first cylinder reverses its movement, causing the first main transfer plate to rise vertically, disengaging one set of rotors from the positioning slot and the other set from the positioning structure. The second cylinder then activates again, driving the first auxiliary transfer plate to move horizontally in the opposite direction. The first cylinder descends again, and the first and second gripper cylinders release the rotors respectively. One set of rotors is placed on the positioning structure of the positioning seat, and the other set is placed on the rotor clamp. Throughout the process, the two gripper cylinders work synchronously, improving transfer efficiency.

[0023] The reciprocating clamp sorting and conveying device for the rotor assembly machine described above can be further configured as follows: the side of the second lifting and transfer component is provided with a discharge mechanism for taking out the assembled rotor. The discharge mechanism includes a third gripper cylinder. The body of the third gripper cylinder is linked to a second rotating cylinder. The body of the second rotating cylinder is linked to a seventh cylinder for driving the second rotating cylinder to reciprocate vertically.

[0024] Using the above technical solution, when the assembled rotor moves with the rotor clamp to near the second lifting and transferring assembly, the seventh cylinder drives the second rotary cylinder and the third gripper cylinder to move downwards vertically. The third gripper cylinder clamps the assembled rotor. Subsequently, the seventh cylinder reverses its movement, causing the second rotary cylinder and the third gripper cylinder to rise vertically, causing the rotor to disengage from the rotor clamp. The second rotary cylinder drives the third gripper cylinder and the clamped rotor to rotate, and the third gripper cylinder releases the rotor, completing the process of removing the assembled rotor.

Detailed Implementation

[0028] 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.

[0029] like Figures 1 to 8The reciprocating fixture sorting and conveying device for the rotor assembly machine shown includes a frame. An upper fixture sorting guide rail 2-1 and a lower fixture sorting guide rail 2-2, arranged parallel to each other, are fixedly mounted on the frame. A first lifting and transferring component is located at one end of the upper fixture sorting guide rail 2-1, and a second lifting and transferring component is located at the other end. The first lifting and transferring component includes a liftable first transfer seat 18 and a first pushing cylinder 19 that pushes the product on the first transfer seat 18 to the upper fixture sorting guide rail 2-1. The output end of the first pushing cylinder 19 corresponds to the upper fixture sorting guide rail 2-1. The body of the first push cylinder 19 is fixed to the frame, and the output end of the first push cylinder 19 corresponds to the upper clamping sorting guide rail 2-1. The first transfer seat 18 is linked to the fifth cylinder 20 and the fifth slider 21. The fifth slider 21 is slidably engaged with the fifth slide rail 22, which is fixed to the frame. The fifth cylinder 20 is used to drive the first transfer seat 18 to reciprocate between the upper clamping sorting guide rail 2-1 and the lower clamping sorting guide rail 2-2. The second lifting and transferring assembly includes a liftable second transfer seat 23 and a second push cylinder 24 that pushes the product on the second transfer seat 23 to the lower clamping sorting guide rail 2-2. The second push cylinder 24 corresponds to the lower clamping sorting guide rail 2-2. The body of the second push cylinder 24 is fixed on the frame, and the output end of the second push cylinder 24 corresponds to the lower fixture sorting guide rail 2-2. The second transfer seat 23 is linked to the sixth cylinder 25 and the second transfer seat 23 is linked to the sixth slider 27. The sixth slider 27 is slidably engaged with the sixth slide rail 28. The sixth slide rail 28 is fixed on the frame. The sixth cylinder 25 is used to drive the second transfer seat 23 to reciprocate between the upper fixture sorting guide rail 2-1 and the lower fixture sorting guide rail 2-2.

[0030] The upper clamping sorting guide rail 2-1 is provided with a first clamping material transport groove 2-3 arranged along the axial direction of the upper clamping sorting guide rail 2-1. The two ends of the first clamping material transport groove 2-3 are open towards the first lifting and transferring assembly and the second lifting and transferring assembly, respectively. The lower clamping sorting guide rail 2-2 is provided with a second clamping material transport groove 2-4 arranged along the axial direction of the lower clamping sorting guide rail 2-2. The two ends of the second clamping material transport groove 2-4 are open towards the second lifting and transferring assembly, respectively. Several sets of rotor clamps 1 are evenly distributed in the first clamping material transport groove 2-3 and the second clamping material transport groove 2-4. Each pair of adjacent sets of rotor clamps 1 located in the first clamping material transport groove 2-3 or the second clamping material transport groove 2-4 abut against each other. The first and second clamping material transport grooves 2-4 serve as axial guide channels, limiting the movement trajectory of the rotor clamps 1, preventing the rotor clamps 1 from shifting laterally or flipping during transportation, and ensuring that the rotor clamps 1 are always aligned with the positioning reference of the subsequent assembly station. The mutual abutment of adjacent rotor clamps 1 within the two clamping material conveying slots creates a "linked pushing" effect through mechanical contact. When the first rotor clamp 1 is pushed, all subsequent rotor clamps 1 transmit power sequentially through the abutment force. This eliminates the need for a separate drive device for each clamp, reducing costs while achieving a tight arrangement of clamps and maximizing the use of guide rail space. Furthermore, this solution allows for rapid adjustment of the "single movement distance" of the rotor clamps 1, requiring only adjustment of the extension distance of the two pushing cylinders.

[0031] The first clamping material conveying groove 2-3 has a first support surface 2-5 distributed on both sides of the first clamping material conveying groove 2-3 below it, and a first strip-shaped hollow groove 2-6 is provided between the two sets of first support surfaces 2-5; the second clamping material conveying groove 2-4 has a second support surface 2-7 distributed on both sides of the second clamping material conveying groove 2-4 below it, and a second strip-shaped hollow groove 2-8 is provided between the two sets of second support surfaces 2-7. The first and second support surfaces 2-7 serve as the bearing surfaces on both sides of the conveying groove, providing symmetrical support for the rotor clamp 1, avoiding tilting or jamming of the rotor clamp 1 due to unilateral force or center of gravity shift, and ensuring the stability of the transportation process. The first strip-shaped hollow groove 2-6 and the second strip-shaped hollow groove 2-8 reduce the contact area between the lower end of the rotor clamp 1 and the clamping sorting guide rail, thereby reducing static friction and improving the smoothness of the movement of the rotor clamp 1 within each set of clamping material conveying grooves, avoiding jamming.

[0032] The first transfer seat 18 includes a first transfer groove 18-1, both ends of which are open. Below the first transfer groove 18-1, there are third support surfaces 18-2 distributed on both sides of the first transfer groove 18-1. A third strip-shaped perforated groove 18-3 is provided between the two sets of third support surfaces 18-2. The second transfer seat 23 has the same structure as the first transfer seat 18. The third support surfaces 18-2 serve as the bearing surfaces on both sides of the transfer groove, providing symmetrical support for the rotor clamp 1, preventing tilting or jamming of the rotor clamp 1 due to unilateral force or center of gravity shift, and ensuring the stability of the transportation process. By setting the third strip-shaped perforated groove 18-3, the contact area between the lower end of the rotor clamp 1 and the two transfer seats is reduced, thereby reducing static friction, improving the smoothness of movement of the rotor clamp 1 within each set of transfer grooves, and preventing jamming.

[0033] Rotor clamp 1 transport principle: When transporting rotor clamp 1, the first transfer seat 18 and the second transfer seat 23 move upward synchronously, aligning and connecting with both ends of the upper clamp sorting guide rail 2-1. The first push cylinder 19 pushes the rotor clamp 1 on the first transfer seat 18 into the first clamp conveying groove 2-3 of the upper clamp sorting guide rail 2-1. The rotor clamp 1 at the other end, under the resistance of the preceding rotor clamp 1, enters the second transfer seat 23 along the upper clamp sorting guide rail 2-1. Subsequently, the first transfer seat 18 and the second transfer seat 23 are driven downward synchronously by the fifth cylinder 20 and the sixth cylinder 25, aligning and connecting with both ends of the lower clamp sorting guide rail 2-2. The second push cylinder 24 pushes the rotor clamp 1 in the second transfer seat 23 into the second clamp conveying groove 2-4 of the lower clamp sorting guide rail 2-2. The first transfer seat 18 then catches the rotor clamp 1 that is pushed out of the lower clamp sorting guide rail 2-2 by the linkage. This cycle repeats, forming a reciprocating cyclical pattern of "upper guide rail forward conveying - lower guide rail reverse return," enabling efficient and orderly transportation of rotor clamp 1 within the assembly machine.

[0034] The first lifting and transferring assembly has a rotor loading mechanism on its side for orderly transport of rotors. The rotor loading mechanism includes a first vibrating feeder 3, a first rotary cylinder 5 distributed between the first vibrating feeder 3 and the upper clamping sorting guide rail 2-1, and a first transfer mechanism for transferring the rotor from the first vibrating feeder 3 to the first rotary cylinder 5 and / or for transferring the rotor from the first rotary cylinder 5 to the rotor clamp 1 within the upper clamping sorting guide rail 2-1. The first vibrating feeder 3 drives the rotor to initially sort and continuously transport along its conveying path through regular vibration. The first transfer mechanism transfers the rotor from the first vibrating feeder 3 to the first rotary cylinder 5, which drives the rotor to rotate until it can be clamped into the rotor clamp 1. The adjusted rotor can be transferred again by the first transfer mechanism to the rotor clamp 1 of the upper clamp sorting guide rail 2-1. The rotor clamp 1 moves with the reciprocating clamp sorting conveyor to enter the subsequent process. The entire process achieves continuous and orderly feeding of the rotor through the initial sorting of the first vertical vibration feeder 3, the direction adjustment of the first rotary cylinder 5 and the connection of the first transfer mechanism.

[0035] A rotor sorting guide rail 4 is installed above the first vertical vibration feeder 3. The rotor sorting guide rail 4 has rotor conveying grooves 41 arranged axially along it. A positioning block 6 is connected to the end of the rotor sorting guide rail 4 facing the first rotary cylinder 5. The positioning block 6 has a rotor positioning groove 61, which has an opening on the side facing the rotor sorting guide rail 4, and the rotor positioning groove 61 communicates with the rotor conveying groove 41 through the opening. A positioning seat 7 is linked to the output end of the first rotary cylinder 5. A positioning structure 71 is provided on the positioning seat 7. When the first transfer mechanism transfers the rotor from the rotor conveying groove 41 to the positioning structure 71 on the positioning seat 7, the first rotary cylinder 5 drives the positioning seat 7 to rotate, and then the positioning structure 71 synchronously drives the rotor to rotate. When the first transfer mechanism transfers the rotor, which has been initially sorted by the rotor sorting guide rail 4, to the positioning structure 71 on the positioning seat 7, the positioning structure 71 can be configured as a positioning hole adapted to the bottom of the rotor or a protrusion inserted into the bottom of the rotor, so that the positioning structure 71 and the rotor engage, fixing the rotor to the positioning seat 7. At this time, the output end of the first rotary cylinder 5 drives the positioning seat 7 to rotate synchronously. Due to the effect of the positioning structure 71, the rotor rotates synchronously with the positioning seat 7 until it can be clamped into the rotor fixture 1. Then the first rotary cylinder 5 stops operating, and the first transfer mechanism transfers the rotor from the positioning seat 7 to the rotor fixture 1 for sorting and loading parts, and enters the subsequent inspection and final calibration process.

[0036] The first transfer mechanism includes a first main transfer plate 8 and a first auxiliary transfer plate 9. One end of the first main transfer plate 8 is linked to a first gripper cylinder 10 for transferring the rotor from the rotor positioning slot 61 to the positioning structure 71, and the other end of the first main transfer plate 8 is linked to a second gripper cylinder 11 for transferring the rotor from the positioning structure 71 to the rotor clamp 1. The first main transfer plate 8 is linked to a first cylinder 12 for driving the first main transfer plate 8 to reciprocate vertically. The body of the first cylinder 12 is mounted on the first auxiliary transfer plate 9. The first main transfer plate 8 is linked to a first slider 13, which is slidably engaged with a first slide rail 14 mounted on the first auxiliary transfer plate 9. The first auxiliary transfer plate 9 is linked to a second cylinder 15 for driving the first auxiliary transfer plate 9 to reciprocate horizontally. The body of the second cylinder 15 is fixed on the frame. The first auxiliary transfer plate 9 is linked to a second slider 16, which is slidably engaged with a second slide rail 17 mounted on the frame. The second cylinder 15 is activated first, driving the first auxiliary transfer plate 9 to move horizontally along the second slide rail 17 until the first gripper cylinder 10 on the first main transfer plate 8 aligns with the positioning block 6 (rotor positioning groove 61) at the end of the rotor sorting guide rail 4. At the same time, the second gripper cylinder 11 on the first main transfer plate 8 aligns with the positioning structure 71. Then, the first cylinder 12 is activated, pushing the first main transfer plate 8 vertically downward along the first slide rail 14. The grippers of the first gripper cylinder 10 open and clamp the rotor in the rotor positioning groove 61, while the grippers of the second gripper cylinder 11 open and clamp the rotor at the positioning structure 71. The first cylinder 12 reverses its action, causing the first main transfer plate 8 to rise vertically, causing one set of rotors to disengage from the positioning groove and the other set of rotors to disengage from the positioning structure 71. The second cylinder 15 actuates again, driving the first auxiliary transfer plate 9 to move horizontally in the opposite direction. The first cylinder 12 descends again, and the first gripper cylinder 10 and the second gripper cylinder 11 release the rotors respectively. One set of rotors is placed on the positioning structure 71 of the positioning seat 7, and the other set of rotors is placed on the rotor clamp 1. Throughout the process, the two gripper cylinders work synchronously, improving the transfer efficiency.

[0037] The working principle of the rotor feeding mechanism is as follows: Firstly, a vibrating feeder continuously transports the rotor into the first vibrating feeder 3, and the rotors are arranged orderly on the first vibrating feeder 3. Next, the rotor is transported by the first gripper cylinder 10 to the rotor positioning slot 61 and then to the positioning structure 71 on the positioning seat 7. The first rotary cylinder 5 drives the rotor to rotate 90 degrees until the rotor is rotated to a position where it can be clamped into the rotor fixture 1. Then, the second gripper cylinder 11 continues to transport the rotor into the rotor fixture 1, and the rotor fixture 1 drives the rotor to the next process for assembly.

[0038] It should be noted that in this embodiment, the first gripper cylinder 10 and the second gripper cylinder 11 in the first transfer mechanism work synchronously. That is, when the first gripper cylinder 10 transfers the rotor in the rotor positioning groove 61, the second gripper cylinder 11 also synchronously transfers the rotor at the positioning seat 7, resulting in high working efficiency and no delay.

[0039] The second lifting and transferring assembly has a discharge mechanism on its side for removing the assembled rotor. The discharge mechanism includes a third gripper cylinder 29, which is linked to a second rotary cylinder 30. The second rotary cylinder 30 is also linked to a seventh cylinder 31 for driving it to reciprocate vertically. When the assembled rotor moves close to the second lifting and transferring assembly along with the rotor clamp 1, the seventh cylinder 31 drives the second rotary cylinder 30 and the third gripper cylinder 29 to move downwards vertically. The third gripper cylinder 29 clamps the assembled rotor. Then, the seventh cylinder 31 reverses its movement, causing the second rotary cylinder 30 and the third gripper cylinder 29 to rise vertically, disengaging the rotor from the rotor clamp 1. The second rotary cylinder 30 then rotates the third gripper cylinder 29 and the clamped rotor, releasing the rotor and completing the removal of the assembled rotor.
