[0002] Stator injection molding is a key process in the field of motor manufacturing. Its full name is stator winding injection molding. Its core purpose is to use specific insulating materials (usually epoxy resin) to precisely inject and fill liquid materials into the stator core slots, between winding coils and all gaps at the ends under vacuum and high pressure. Then, it is heated and cured to form a complete, dense and strong insulating protective body.

[0003] In the stator injection molding process, the stator windings need to be pinned first, that is, the terminals are inserted into the stator windings and connected to them. Existing patent 202421836473.0 describes a rotary terminal pin insertion device, which includes a frame, a servo rotary platform and a terminal feeding mechanism on the frame. Multiple positioning carriers are fixedly connected to the turntable of the servo rotary platform.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] As mentioned in the background section of this application, research has found that existing PIN pin insertion devices have complex structures and cumbersome insertion processes. They also lack measures to detect whether the pins are in place, making it impossible to detect abnormalities in a timely manner, which has certain drawbacks.

[0024] To address the aforementioned shortcomings, this application discloses a continuous pin insertion device for stator injection molding production. This device has a simple structure, simplifies the pin insertion process, improves efficiency, and can detect whether the pins are in place, thus promptly identifying any abnormalities.

[0025] The following will describe in detail, with reference to the accompanying drawings, how the solution of this application solves the above-mentioned technical problems.

[0026] Please see Figures 1-7In this embodiment of the invention, a continuous pin insertion device for stator injection molding production includes a lower housing 1, an upper housing 3 fixedly connected to the top of the lower housing 1, and an upper chamber 4 opened inside the upper housing 3.

A rotating material support mechanism is provided on one side of the bottom end face of the upper chamber 4, and a flipping feeding mechanism is fixedly connected to one side of the rotating material support mechanism. A vibrating feeding mechanism is provided on the side of the flipping feeding mechanism away from the rotating material support mechanism, and a pin-grabbing and insertion mechanism is provided above the vibrating feeding mechanism. This application, through the provided rotating material support mechanism, vibrating feeding mechanism, flipping feeding mechanism, and pin-grabbing and insertion mechanism, can quickly and accurately complete the pin insertion of the stator winding 8. The entire process is simple, efficient, and highly automated. Compared with the prior art, the overall structure is simpler, and the pin insertion steps are more streamlined, effectively improving pin insertion efficiency.

[0027] In this embodiment, the lifting reference mechanism specifically includes: a vertical linear guide rail 44 fixed on the inner wall of one side of the upper chamber 4; a vertical linear motor 45 movably connected to the outer side of the vertical linear guide rail 44; a horizontal plate 46 fixedly connected to one side of the vertical linear motor 45; a slot 47 opened at the end of the horizontal plate 46 away from the vertical linear motor 45; a rotating roller 48 rotatably connected inside the slot 47; a stepper motor 50 fixedly connected to one side of the horizontal plate 46 corresponding to the position of the rotating roller 48; the output shaft of the stepper motor 50 fixedly connected to the rotating roller 48; and four evenly distributed rectangular plates 49 fixedly connected to the outer side of the rotating roller 48, each rectangular plate 49 having a different color on its surface. The lifting reference mechanism not only helps the camera 51 quickly determine whether each terminal 24 is plugged in, but also allows for the adjustment of different colored background reference plates, i.e., rectangular plates 49, to create a clear contrast with the top of the terminal 24, thereby better determining the plugging position of the terminal 24. In addition, this setting facilitates the unified detection of the positions of multiple terminals 24 at one time, which not only improves detection efficiency, but also further improves detection accuracy through comparison between each terminal 24.

[0028] In this embodiment, the rotating material support mechanism specifically includes: a column 6 fixed to the bottom surface of the upper chamber 4; a positioning platform 7 rotatably connected to the top of the column 6; a stator winding 8 sleeved on the outside of the positioning platform 7; a lower chamber 2 opened inside the lower housing 1; four rectangularly distributed connecting rods 9 fixedly connected to the top surface of the lower chamber 2; a drive motor 10 fixedly connected to the bottom ends of the four connecting rods 9; and a transmission shaft 11 fixedly connected to the top output shaft of the drive motor 10. The top end of the transmission shaft 11 passes through the column 6 and is fixedly connected to the positioning platform 7. The rotating material support mechanism can provide limiting support for the stator winding 8 and drive the stator winding 8 to rotate when needed to complete continuous pin insertion.

[0029] In this embodiment, the vibration feeding mechanism specifically includes: a vibration feeding disk 12 fixed on the other side of the bottom end face of the upper chamber 4; a linear vibration base plate 13 fixedly connected to one side of the vibration feeding disk 12; a linear vibration feeder 14 provided at the top of the linear vibration base plate 13; a linear vibration channel mounting seat 15 provided at the top of the linear vibration feeder 14; and a linear vibration channel 16 provided at the top of the linear vibration channel mounting seat 15. One end of the linear vibration channel 16 is connected to the discharge port of the vibration feeding disk 12, and the other end of the linear vibration channel 16 is connected to the flipping feeding mechanism. The vibration feeding mechanism can quickly and orderly feed the terminals 24 to the flipping feeding mechanism.

[0030] In this embodiment, a stop-vibration sensor 17 is fixedly connected to one end of the outer side of the linear vibrating feeder 16 near the vibrating feeder 12, and a terminal position sensor 18 is fixedly connected to one end of the outer side of the linear vibrating feeder 16 near the flipping feeding mechanism. The stop-vibration sensor 17 is used to monitor the operating status of the linear vibrating feeder 14, and the terminal position sensor 18 is used to detect whether the terminal 24 is in position.

[0031] In this embodiment, the flipping feeding mechanism specifically includes: an L-shaped support base 19 fixed to the bottom surface of the upper chamber 4; a fixed base 20 fixedly connected to the top of one side of the L-shaped support base 19; a vane-type swing cylinder 21 embedded inside the fixed base 20; a receiving tray 22 fixedly connected to the output shaft of the vane-type swing cylinder 21; and a slot 23 matching the terminal 24 opened on the outer side of the receiving tray 22. Fiber optic sensors 25 are symmetrically fixedly connected to both sides of the fixed base 20. Through the designed flipping feeding mechanism, not only can the terminal 24 be accurately received from the vibrating feeding mechanism, but the terminal 24 can also be flipped, changing it from a horizontal state to a vertical state, thereby facilitating the subsequent gripping of the pin insertion mechanism. This plays a crucial role in connecting the upper and lower parts of the process, making the entire pin insertion process more efficient and improving pin insertion efficiency.

[0032] In this embodiment, the pin-grabbing and insertion mechanism specifically includes: a base plate 26 fixed to the bottom end face of the upper chamber 4; a top plate 28 above the base plate 26; four uprights 27 fixedly connected between the base plate 26 and the top plate 28; two parallel transverse linear slide rails 29 fixedly connected to the top surface of the top plate 28; transverse slide blocks 30 movably connected to the top of the transverse linear slide rails 29; an L-shaped support plate 31 fixedly connected to the top of the two transverse slide blocks 30; a support frame 35 fixedly connected to one side of the top surface of the L-shaped support plate 31; and a vertical plate 33 fixedly connected to one side of the top surface of the top plate 28 near the edge. A cylinder 34 is fixedly connected to one side of the support frame 35. The output shaft of the cylinder 34 is fixedly connected to the L-shaped support plate 31. A lifting frame 37 is fixedly connected to one side of the bottom surface of the L-shaped support plate 31. A lifting seat 40 is movably connected to one side of the lifting frame 37. A limiting sliding component is provided between the lifting seat 40 and the lifting frame 37. A ball nut 42 is embedded in the top surface of the lifting seat 40, and a ball screw 43 is inserted through the ball nut 42. A drive motor 36 is fixedly connected to the top of the support frame 35, and the bottom output shaft of the drive motor 36 is fixedly connected to the top of the ball screw 43. A pneumatic gripper 41 is fixedly connected to the bottom surface of the lifting seat 40. Through the set needle insertion mechanism, compared with the traditional needle insertion device, the use of a more precise ball screw 43 and ball nut 42 makes the needle insertion effect better. The overall structure is simple while maintaining high flexibility, which can make the final needle insertion work more efficient.

[0033] In this embodiment, a limiting plate 32 is fixedly connected to the other side of the top surface of the top plate 28 near the edge. The limiting plate 32 can abut against and prevent the L-shaped support plate 31 from detaching from the top plate 28.

[0034] In this embodiment, the limiting sliding member specifically includes: a vertical linear slide rail 38 fixed to the outer surface of the lifting frame 37, a vertical slide block 39 movably connected to the outer surface of the vertical linear slide rail 38, and the vertical slide block 39 being fixedly connected to the lifting seat 40. This arrangement ensures that the lifting seat 40 will not separate from the lifting frame 37.

[0035] In this embodiment, gratings 5 ​​are symmetrically fixedly connected to the inner walls on both sides of the opening of the upper chamber 4 to provide illumination.

[0036] The working principle of this invention is as follows: First, the stator winding 8 to be inserted is placed and fixed on the positioning support 7. Then, the vibratory feeding mechanism starts operating. Specifically, the vibratory feeding plate 12 feeds the terminals 24 within it to the linear vibratory feed channel 16. The linear vibratory feeder 14 drives the linear vibratory feed channel mounting base 15 and the linear vibratory feed channel 16 to vibrate, sequentially conveying the terminals 24 entering the linear vibratory feed channel 16 towards the flipping feeding mechanism. Next, the terminals 24 are inserted along the linear vibratory feed channel 16 into the slots 23 on the receiving plate 22 of the flipping feeding mechanism. Subsequently, the blade-type swing cylinder 21 rotates the receiving plate 22 ninety degrees, causing the terminals 24, which were originally horizontal, to change to a vertically upward position. The terminal 24 is then picked up by the pin-grabbing insertion mechanism. The operation process of the pin-gripping and insertion mechanism is as follows: the cylinder 34 operates to adjust the extension length of the output shaft. Under the constraint of the horizontal linear slide rail 29 and the horizontal slide block 30, the position of the L-shaped support plate 31 is adjusted. First, the pneumatic gripper 41 is adjusted to be directly above the target terminal 24. Then, the ball screw 43 is driven to rotate by the transmission motor 36. Under the constraint of the vertical linear slide rail 38 and the vertical slide block 39, the lifting frame 37 and the lifting block 40 are relatively displaced in the vertical plane, thereby changing the height of the pneumatic gripper 41. After the pneumatic gripper 41 reaches the height of the target terminal 24, the pneumatic gripper 41 clamps the target terminal 24. Then, the pneumatic gripper 41 is raised by the reverse rotation of the transmission motor 36, thereby causing the target terminal 24 to disengage from the slot 23. At this time, the target terminal 24 is disengaged from the flipping feeding mechanism and transferred to the pin-gripping and insertion mechanism. The final pin insertion is then performed via a pin-grabbing and insertion mechanism. Specifically, the mechanism moves the target terminal 24 to directly above the first target pin position on the stator winding 8. The pneumatic gripper 41 then lowers, allowing the target terminal 24 to insert into the first target pin position. After the pneumatic gripper 41 descends to a certain height, it releases the target terminal 24 and returns to its initial state. The first pin insertion is then completed. This process is repeated for the second pin insertion. It should be noted that before the second pin insertion, the drive motor 10 rotates the positioning platform 7 by a preset angle via the transmission shaft 11, causing the second target pin position to replace the first. Repeating this process completes the continuous pin insertion of the stator winding 8.After the stator winding 8 completes the pin insertion of all terminals 24, the lifting reference mechanism assists the camera 51 to quickly determine whether each terminal 24 is properly inserted. Specifically, the vertical linear motor 45 moves and descends a certain height along the vertical linear guide rail 44. At this time, the bottom rectangular plate 49 reaches the designated position. It should be noted that at this time, the horizontal plane at the bottom of the bottom rectangular plate 49 is 10mm higher than the horizontal plane at the top of the terminal 24 after ideal insertion. The camera 51 collects the image of the terminal 24 after insertion and the image of the bottom rectangular plate 49 and sends them to the external background control terminal. The background control terminal uses the rectangular plate 49 as a background reference board and analyzes the insertion position of each terminal 24 through image recognition to determine whether it is accurate. Furthermore, to avoid the rectangular plate 49 being the same color as the terminal 24 to be inserted, which would make reference difficult, the lifting reference mechanism can adjust the background reference plate (i.e., the rectangular plate 49) to different colors as needed, creating a clear contrast with the top of the terminal 24, thus better determining the insertion position of the terminal 24. In addition, this setting facilitates the simultaneous detection of multiple terminal 24 positions, improving detection efficiency and further enhancing detection accuracy through comparison between individual terminals 24. The adjustment process of the rectangular plate 49 involves the stepper motor 50 driving the rotating roller 48 within the slot 47 to rotate, causing the rectangular plate 49 on the rotating roller 48 to rotate accordingly, thereby achieving the adjustment purpose.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
