[0025] The structure of the coil clamping device on the coil frame of a three-phase stepper motor provided by this utility model is as follows: Figure 1 as well as Figure 4 As shown, the machine includes four racks 1 placed side by side. The surface of the rack 1 is provided with an upper claw feeding mechanism 2, which is used for upper claw feeding. The upper claw feeding mechanism 2 includes an upper claw circular vibrating plate 21, an upper claw straight vibrator 22, and a position sensor 23. The upper claw circular vibrating plate 21 and the upper claw straight vibrator 22 are both fixed to the surface of the rack 1, and the discharge port of the upper claw circular vibrating plate 21 is connected to the slide of the upper claw straight vibrator 22. A full material sensor is installed at the discharge port of the upper claw circular vibrating plate 21, and a position sensor 23 for upper claw sensing is provided at the end of the slide of the upper claw straight vibrator 22.

[0026] During implementation, the upper claw circular vibrating plate 21 is started to feed material. The discharge port of the upper claw circular vibrating plate 21 is connected to the slide of the straight vibrator. After the upper claw is pushed to the position sensor 23, the position sensor 23 sends a signal to notify the upper claw feeding mechanism 3 to pick up the upper claw.

[0027] Furthermore, such as Figure 2 as well as Figure 5 As shown, the upper claw feeding mechanism 3 is installed on the surface of the frame 1. The upper claw feeding mechanism 3 is used to transport the upper claw on the upper claw feeding mechanism 2 to the feeding and kneading mechanism 4. The upper claw feeding mechanism 3 consists of a left support 31, a Y-axis cylinder 32, a Y-axis slide 33, a Z-axis cylinder 34, a Z-axis connecting block 35, and an upper claw suction nozzle 36. The left support 31 is fixed to the surface of the frame 1, and the Y-axis cylinder 32 is fixed to the surface of the left support 31. The Y-axis slide 33 is slidably connected to the surface of the left support 31, and the surface of the Y-axis slide 33 is fixed to the output end of the Y-axis cylinder 32. The Z-axis cylinder 34 is fixed to the surface of the Y-axis slide 33, and the Z-axis connecting block 35 is installed at the output end of the Z-axis cylinder 34. The upper claw suction nozzle 36 for adsorbing the upper claw is fixed to the surface of the Z-axis connecting block 35.

[0028] During implementation, the Z-axis cylinder 34 drives the upper claw suction nozzle 36 on the surface of the Z-axis connecting block 35 to descend and pick up the upper claw. Then, after the Z-axis cylinder 34 is lifted, the Y-axis cylinder 32 is sent above the positioning fixture 42 on the Y-axis slide 33.

[0029] Furthermore, such as Figure 1 as well as Figure 6As shown, a feeding and kneading mechanism 4 is provided on one side of the frame 1. The feeding and kneading mechanism 4 includes a feeding track 41, a positioning fixture 42, an induction switch 43, and a positioning cylinder 44. The surface of the feeding track 41 is provided with a positioning fixture 42 with a positioning pin. The positioning fixture 42 is used for the placement of the upper claw suction nozzle 36 to absorb the upper claw. The surface of the feeding track 41 is inlaid with multiple sets of induction switches 43 for sensing the positioning fixture 42. A positioning cylinder 44 with a positioning V-block is installed on one side of the feeding track 41. The positioning cylinder 44 is used to block the positioning fixture 42.

[0030] During implementation, the positioning fixture 42 is transported to the designated position by the belt of the track. The designated position sensor switch 43 senses the position, and the positioning cylinder 44 drives the positioning V-block to extend and lock the positioning fixture 42. Then, the upper claw will be placed on the positioning pin of the positioning fixture 42 from the left and right sides of the upper claw feeding mechanism 3.

[0031] Furthermore, such as Figure 3 as well as Figure 7 As shown, a bobbin feeding mechanism 5 for feeding coil bobbins is installed on the surface of the frame 1. The bobbin feeding mechanism 5 includes a bobbin circular vibrating plate 51, a bobbin straight vibrator 52, a push plate cylinder 53, a push plate 54, and a lever cylinder 55. The bobbin circular vibrating plate 51 and the bobbin straight vibrator 52 are installed on the frame 1, and the discharge port of the bobbin circular vibrating plate 51 is connected to the slide of the bobbin straight vibrator 52. Spring baffles 56 for blocking the coil bobbin are installed on both sides of the end of the slide of the bobbin straight vibrator 52. The surface of the bobbin straight vibrator 52 is equipped with a push plate cylinder 53, and the output end of the push plate cylinder 53 is fixed with a push plate 54. The surface of the push plate 54 is fixed with a lever cylinder 55. The lever cylinder 55 is used to push the coil bobbin blocked by the spring baffles 56.

[0032] During implementation, the upper frame is transported to the spring baffle 56 by the frame circular vibrating plate 51 and the frame straight vibrator 52. The spring baffle 56 first blocks and positions the frame. The lever cylinder 55 drives the lever to go down along the Z-axis and insert it into the center hole of the upper frame. The push plate cylinder 53 drives the push plate 54 to pull it to the front end position.

[0033] Furthermore, such as Figure 3 as well as Figure 8As shown, a skeleton feeding mechanism 6 is provided on one side of the skeleton feeding mechanism 5. The skeleton feeding mechanism 6 is used to pinch the coil skeleton of the skeleton feeding mechanism 5 with the upper claw placed on the feeding pinching mechanism 4. The skeleton feeding mechanism 6 consists of a right support 61, a Y cylinder slide 62, a Z cylinder slide 63 and a finger cylinder 64. The right support 61 is fixed to the surface of the frame 1, and the Y cylinder slide 62 is installed on the surface of the right support 61. The Z cylinder slide 63 is fixed to the slide of the Y cylinder slide 62, and the finger cylinder 64 is installed on the slide of the Z cylinder slide 63. The finger cylinder 64 is used to feed the coil skeleton pushed out by the lever cylinder 55 onto the positioning fixture 42 and pinch it with the upper claw.

[0034] During implementation, the finger cylinder 64 moves down along the left and right lower edges of the Z cylinder slide 63 along the Z axis to lock the skeleton groove. After being lifted in the Z direction, the Y cylinder slide 62 is transported to the top of the positioning fixture 42. At the same time, after the positioning fixture 42 with the upper jaw assembled at the previous station is in the X direction, the finger cylinder 64 drives the skeleton to be loaded into the upper jaw.

[0035] Working principle: Before starting the machine, check that the air, vacuum, control system, vibrating plate, cylinder, etc. are normal.

[0036] First, the upper jaw circular vibrating plate 21 is started to feed material. The discharge port of the upper jaw circular vibrating plate 21 is connected to the slide of the straight vibrator. After the upper jaw is pushed to the position sensor 23, the position sensor 23 sends a signal to notify the upper jaw feeding mechanism 3 to pick up the upper jaw.

[0037] During the suction process, the Z-axis cylinder 34 drives the upper claw suction nozzle 36 on the surface of the Z-axis connecting block 35 to descend and suck up the upper claw. Then, after the Z-axis cylinder 34 is lifted, the Y-axis cylinder 32 is sent to the positioning fixture 42 above the Y-axis slide 33. At the same time, the positioning fixture 42 has been transported to the designated position by the belt of the track. The designated position induction switch 43 senses the position, and the positioning cylinder 44 drives the positioning V-block to extend and lock the positioning fixture 42. Then, the upper claw will be placed on the positioning pin of the positioning fixture 42 on the left and right sides of the upper claw feeding mechanism 3, completing one assembly cycle.

[0038] After the upper jaw is in place, it receives a signal and continues to move to the next station to install the skeleton.

[0039] The upper frame is transported to the spring stop 56 by the frame circular vibrating plate 51 and the frame direct vibrator 52. The spring stop 56 first blocks the positioning. The lever cylinder 55 drives the lever to go down along the Z-axis and insert it into the center hole of the upper frame. The push plate cylinder 53 drives the push plate 54 to the front end position. The finger cylinder 64 goes down along the Z-axis on the left and right sides of the Z cylinder slide 63 to hold the frame groove. After being lifted in the Z direction, the Y cylinder slide 62 is transported to the top of the positioning fixture 42. At the same time, after the positioning fixture 42 with the upper jaw assembled at the previous station is in the X direction, the finger cylinder 64 drives the frame to be loaded into the upper jaw, and after being pressed and lifted back to the original position, one assembly cycle is completed.

[0040] After the upper jaw and upper skeleton are assembled, the positioning fixture 42 continues to move in the X direction with the assembled upper jaw and upper skeleton to assemble the middle and lower jaws and skeleton.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
