The material transfer mechanism 5 is used to transfer the iron core on the material tray storage mechanism 3 to the correction station of the correction mechanism 4. The material transfer mechanism 5 is also used to transfer the iron core after correction by the correction mechanism 4 to the fixture 200 located on the conveyor belt mechanism 2.

[0045] The material tray storage mechanism 3, the straightening mechanism 4, and the material transfer mechanism are all set on the upper surface of the workstation 1. Compared with the traditional manual feeding method, the present invention can realize fully automated processing, which greatly improves efficiency, accuracy and processing quality, further reduces production costs, and is easy to operate. As for replenishing the material tray at regular intervals, it can effectively prevent the upper and lower ends of the iron core from being reversed, which would affect subsequent processing.

[0046] Preferably, the correction mechanism 4 includes a horizontally arranged first feeding guide rail 41, a detection unit 42 located at one end of the first feeding guide rail 41 for detecting the position of the iron core 100, a feeding plate 43 located above the first feeding guide rail 41, a feeding drive unit 44 for driving the feeding plate 43 to move along the first feeding guide rail 41, a correction shaft 45 located on the upper surface of the first feeding guide rail 41, and a correction drive unit 46 for driving the correction shaft 45 to rotate; wherein, the detection unit 42 can be a laser sensor, an infrared sensor, or a CCD sensor for further correction.

When assembled, the end face of the straightening shaft near the first feeding guide rail 41 is located above the first feeding guide rail 41. In the initial state, the lower inner wall of the feeding groove 7 is flush with the upper surface of the first feeding guide rail 41. Furthermore, the correction mechanism 4 also includes a removal drive unit 47 that drives the material-pushing plate 43 to move away from the first feeding guide rail 41. The material-pushing drive unit 44 is located on the movable terminal of the removal drive unit 47. The end face of the material-pushing plate 43 near the first feeding guide rail 41 is longitudinally provided with a positioning groove 8 that is adapted to the iron core. Specifically, the positioning groove 8 is a notch groove and it is perpendicular to the direction of the first feeding guide rail 41, so as to facilitate the left and right movement of the iron core along the first feeding guide rail. The inner wall of the feeding groove 7 is provided with a magnet 9 for adsorbing the iron core, so that the material-pushing plate 43 can remove the iron core from the material. One end of the first feeding guide rail 41 is pushed through the feeding groove 7 and reaches the other end, and the position is detected by the detection unit 42. When the position of the upper and lower ends of the iron core is reversed, the iron core is pushed into the feeding groove 7 by the feeding plate 43. After it is in place, the feeding plate 43 moves out of the feeding groove 7, and the straightening shaft 45 rotates up and down 180 degrees to straighten the iron core. After the straightening, the feeding plate 43 resets and enters the feeding groove 7 to push the straightened iron core to the detection station and waits for the transfer mechanism to take it away. During the process of the straightening shaft 45 flipping, the iron core is attracted and fixed by the magnet 9 to prevent it from falling off.

[0047] Preferably, the material transfer mechanism 5 includes a second material feeding guide 51 for holding iron cores, a first material picking robot 52 for moving iron cores from the tray on the tray storage mechanism 3 into the second material feeding guide 51, a transition transfer module 53 for moving iron cores from the second material feeding guide 51 to the first material feeding guide 41, and a second material picking robot 54 for moving the calibrated iron cores on the first material feeding guide 41 into the fixture 200 on the conveyor belt mechanism 2. The second material feeding guide 51 is horizontally arranged side by side with the first material feeding guide 41 on the side away from the calibrating mechanism 4 to facilitate the handling of the second material picking robot 54 and shorten the stroke. Furthermore, a vertical vibrator 10 is provided on the lower surface of the second material feeding guide 51. The vibration direction of the vertical vibrator 10 is perpendicular to the longitudinal direction of the second material feeding guide 51 to facilitate the movement of the iron cores along the second material feeding guide 51. In addition, the second material picking robot 54 is specially provided to facilitate placing the iron cores into the corresponding positions of the positioning slot 8.

[0048] Preferably, there are two correction mechanisms 4, which are arranged side by side along the movement direction of the conveyor belt mechanism 2; there are two second feeding guides 51 corresponding to the two correction mechanisms 4, both second feeding guides 51 are inclined and their adjacent ends are connected to form an inverted V-shaped structure, the material release position of the first picking robot 52 is located above the adjacent ends of the two second feeding guides 51, and the adjacent ends of the first feeding guide 41 and the second feeding guide 51 are connected to the vibration terminal of the straight vibrator 10. Dual-station feeding can be realized through one straight vibrator 10, and two stations can be fed by one loading of the first picking robot 52, which is more efficient.

[0049] Preferably, the transition transfer module 53 includes a receiving plate 531 coplanar with the second feeding guide rail 51. The receiving plate 531 is provided with a receiving groove 11 that is adjacent to and aligned with the discharge port 511 of the second feeding guide rail 51. Specifically, the receiving groove 11 is a notched groove and is directly opposite the discharge port, so that the positioning groove 8 on the feeding plate 43 can align with the core and limit its left and right positions. The transition transfer module 53 also includes a receiving and transfer unit 532 that drives the receiving plate 531 to move to the inlet end 411 of the first feeding guide rail 41. Through the cooperation of the receiving plate 531 and the receiving and transfer unit 532, the iron cores can be fed one by one into the first feeding guide rail 41. To facilitate the alignment of the positioning groove 8 on the feeding plate 43 with the iron core, and further, to prevent the iron core from falling out when the receiving plate moves away from the discharge port 511 of the second feeding guide rail 51, an extension 53a is provided on the receiving plate 531. When the receiving plate is connected to the first feeding guide rail for feeding, the extension is used to block the discharge port 511. Specifically, the first picking robot 52 and the second picking robot 54 both include a gripper a1 for picking up the iron core, a Y-axis lifting unit a2 for driving the gripper a1 to rise and fall, and an X-axis transverse movement unit a3 for driving the Y-axis lifting unit a2 to move horizontally; the movement direction of the X-axis transverse movement unit a3 is perpendicular to the conveyor belt mechanism 2.

[0050] Preferably, the tray storage mechanism 3 includes a tray storage device 31, which includes two horizontally opposite support plates 311, a feeding lifting unit 312 that drives the support plates 311 to rise and fall, and a feeding separation module 313 that drives one feeding lifting unit 312 to reciprocate horizontally toward the other feeding lifting unit 312; the gap between the two support plates 311 forms a feeding channel, and the tray storage mechanism 3 also includes a receiving platform 32 disposed on the feeding channel; the lower end of the receiving platform 32 is provided with a receiving lifting unit 12, and below the receiving platform 32 is a horizontal movement mechanism that drives the receiving lifting unit 12 to move horizontally away from the feeding channel. In the initial state, the two ends of the material tray are placed on the two support plates 311 respectively. When feeding is required, the horizontal moving unit 13 drives the receiving platform 32 to move below the material tray. The receiving lifting unit 12 drives the receiving platform 32 to rise and hold the material tray. Furthermore, the two support plates 311 are horizontally moved away from the bottom of the material tray by the unloading separation module 313 and reset to the bottom of the upper material tray to prevent the upper material tray from falling. This makes the bottom material tray completely placed on the receiving platform 32. After it is in place, the receiving platform 32 falls and moves out from under the support plate 311 by the horizontal moving unit 13, which makes it convenient for the first picking robot 52 to pick up the material.

[0051] Preferably, the material tray storage mechanism 3 further includes an empty tray storage device 33 located at the end of the transverse unit 13 opposite to the support plate 311. The empty tray storage device 33 includes a mounting frame 331 located above the transverse unit 13 and two movable plates 332 horizontally arranged side by side on the mounting frame 331. The movable plates 332 are horizontally arranged and longitudinally rotatably connected to the mounting frame 331. The mounting frame 331 has an inlet window below the movable plates 332 for the material tray to pass through vertically. The movable plates 332 have an extension 33a extending above the inlet window, and the upper end of the extension 33a has an upward support. The support position 33b of the material tray and the mounting frame 331 are also provided with a support platform 14 to prevent the end of the movable plate 332 from falling away from its pivot. When it is necessary to store an empty tray, the transverse unit 13 transports the empty tray to the bottom of the storage window. The empty tray is driven to rise through the storage window by the receiving lifting unit 12. The adjacent ends of the two movable plates 332 are flipped upward by the empty tray. After the empty tray passes the movable plate 332, the free end of the movable plate 332 is reset and stops on the support platform 14. At this time, the receiving lifting unit 12 descends so that the empty tray stops on the two movable plates 332, thereby realizing empty tray storage.

[0053] Step S10: The jig 200 for fixing the iron core is transported to the position by the conveyor belt mechanism 2. When it is in position, the jig 200 and the straightening mechanism 4 are side by side and facing each other.

[0054] Step S20: The iron core located on the material tray storage mechanism 3 is moved to the straightening mechanism 4 by the material transfer mechanism 5;

[0055] Step S30: The vertical position of the iron core is detected by the correction mechanism 4 and the iron core with the position reversed is corrected;

[0056] Step S40: Transfer the corrected iron core to the fixture 200 located on the conveyor belt mechanism, and transfer the fixture 200 loaded with the iron core to the next work station via the conveyor belt mechanism.
