[0022] Please see Figure 1-9 An inductor U-shaped coil leveling and forming equipment includes a control system 1, an electrically controlled feeding mechanism 2, a leveling and fitting mold 3, an electrically controlled leveling mechanism 4, and an electrically controlled unloading mechanism 5.

[0025] In some embodiments, the inductor U-shaped coil leveling and forming equipment further includes a frame 6, on which an electrically controlled operating mechanism 7, a feeding station 601, a leveling station 602, and a unloading station 603 are provided.

[0026] The electrically controlled operating mechanism 7 is used to sequentially and cyclically move the leveling and fitting mold 3 to the loading station 601, the leveling station 602 and the unloading station 603.

[0027] The electrically controlled feeding mechanism 2 is set at the feeding station 601, the electrically controlled leveling mechanism 4 is set at the leveling station 602, and the electrically controlled unloading mechanism 5 is set at the unloading station 603.

[0028] In some embodiments, multiple leveling and fitting molds are provided, and the electrically controlled operating mechanism 7 is used to sequentially and cyclically operate the multiple leveling and fitting molds to the loading station 601, the leveling station 602 and the unloading station 603. Multiple stations can operate simultaneously, resulting in higher efficiency.

[0029] In some embodiments, the electrically controlled operating mechanism includes an indexing plate 701, and a plurality of leveling and mating molds 3 are arranged in a ring at intervals on the turntable of the indexing plate 701. The indexing plate 701 rotates the leveling and mating molds 3 sequentially and cyclically to the loading station 601, the leveling station 602 and the unloading station 603.

[0030] For example, the rotation axis of the indexing plate is set vertically, and correspondingly, the loading station, leveling station and unloading station are arranged at intervals around the indexing plate.

[0031] In some embodiments, the electronically controlled feeding mechanism 2 includes a vibratory feeder 201, which automatically vibrates and arranges the pre-bent coils 9 from the straight vibratory guide rail of the vibratory feeder 201.

[0032] The electrically controlled feeding mechanism 2 also includes a first vertical moving component 202, a first rotating component 203 and a first electrically controlled gripper 204. The first horizontal moving component and the first rotating component are used together to drive the electrically controlled gripper to move in multiple degrees of freedom. The first electrically controlled gripper grabs the pre-bent coils arranged on the vibratory plate and places them on the leveling and mating mold that is moved to the feeding station.

[0033] In some embodiments, the first horizontal movement component includes a first cylinder guide rail slider assembly mounted on a frame.

[0034] The first rotating assembly includes a rotary cylinder mounted on a slider of the first cylinder guide slider assembly.

[0035] The first electric gripper includes a pneumatic gripper mounted on a turntable of a rotary cylinder, the rotary cylinder having a horizontal rotation axis.

[0036] In some embodiments, the top of the leveling mold 3 has a cavity 301 corresponding to the middle bending portion 10 of the pre-bent coil, and leveling support portions 302 corresponding to the side bending portions 11 of the pre-bent coil are provided on both sides of the cavity 301.

[0037] For example, the middle bend of the pre-bent coil is placed on the cavity of the leveling and fitting mold with the middle bend facing downwards, so that the opening 12 of the middle bend of the pre-bent coil faces upwards, and the side bend of the pre-bent coil is supported by the leveling support.

[0038] In some embodiments, the electronically controlled leveling mechanism 4 includes a leveling drive assembly 401 and a leveling die punch 402, wherein the leveling drive assembly 401 drives the leveling die punch 402 to move up and down.

[0039] When the leveling die is moved to the leveling station, the leveling die punch can be driven downward by the leveling drive assembly. The leveling die punch cooperates with the leveling die to press and level the pre-bent coil 9 on the leveling die, especially to level the side bending part 11 of the pre-bent coil.

[0040] It can be understood that the leveling drive assembly, the leveling die punch, and the leveling mating die at this time constitute the punch press.

[0041] In some embodiments, the leveling drive component may be an up-and-down drive component that uses a motor as a power source.

[0042] In some embodiments, the leveling die punch 402 has a leveling portion 4021 corresponding to the side bending portion of the pre-bent coil, and a positioning portion 4022 that can be inserted from the opening of the middle bending portion of the pre-bent coil.

[0043] The leveling part 4011 and the leveling support part 302 are used to press and level the side bending part of the pre-bent coil, and the positioning part 4022 and the mold cavity 301 are used to position the pre-bent coil to ensure the leveling quality.

[0044] In some embodiments, the electrically controlled feeding mechanism 5 includes a second horizontal moving component 501, a second vertical moving component 502, a second electrically controlled gripper 503, and a feeding tray 504.

[0045] The second horizontal moving component and the second vertical moving component work together to drive the second electrically controlled gripper. The second electrically controlled gripper grabs the zigzag coil on the leveling and mating mold that has been moved to the unloading station and places it in the unloading tray.

[0046] In some embodiments, the second horizontal movement component includes a second cylinder guide rail slider assembly mounted on a frame.

[0047] The second vertical movement assembly includes a third cylinder guide rail slider assembly mounted on the slider of the second cylinder guide rail slider assembly.

[0048] The second electric gripper includes a pneumatic gripper mounted on the slider of the second cylinder guide rail slider assembly.

[0049] In some embodiments, the interior of the leveling mold 3 is provided with an ejector pin hole 303 that communicates with the mold cavity 301. An upper and lower sliding guide rail 304 is provided on the ejector pin hole 303. A guide slider 305 is slidably provided on the upper and lower sliding guide rail 304. An ejector pin 306 corresponding to the mold cavity 301 is connected to the guide slider 305. The ejector pin 306 can be inserted into the mold cavity 301 to lift the Z-shaped coil 13.

[0050] The bottom of the leveling mold 3 is provided with a lifting hole 307 that connects to the ejector pin hole 303, and the lifting hole 307 is configured to correspond to the guide slider 305.

[0051] The electronically controlled feeding mechanism 5 also includes a top material drive assembly 505 and a top material pusher 506.

[0052] When the leveling and fitting mold 3 is driven to the unloading station 603 by the indexing plate 701, the ejector pusher 506 is located below the lifting hole 307 and corresponds vertically to the lifting hole 307.

[0053] The ejector drive assembly 505 drives the ejector pusher 506 to go upward into the lifting hole 307, thereby pushing the guide slider 305 upward. The guide slider 305 drives the ejector post 306 to go upward into the mold cavity 301 to lift the Z-shaped coil 13. The ejector drive assembly 505 drives the ejector pusher 506 to go downward out of the lifting hole 307, so that the indexing plate 701 can drive the leveling and fitting mold 3 to move to other stations.

[0054] In some embodiments, the inductor U-shaped coil leveling and forming equipment further includes a cavity detection mechanism 8, which is used to detect whether a pre-bent coil 9 is placed on the leveling and mating mold 3.

[0055] In some embodiments, a testing station 604 is provided on the frame 6, and the hole entry testing mechanism 8 is provided on the testing station 604.

[0056] The electrically controlled operating mechanism 7 is used to sequentially and cyclically move the leveling and fitting mold 3 to the loading station 601, the inspection station 604, the leveling station 602, and the unloading station 603.

[0057] For example, the loading station, inspection station, leveling station, and unloading station are arranged at intervals around the indexing plate.

[0058] In some embodiments, the hole entry detection mechanism 8 includes a lifting drive assembly 801 and a detection column 802, wherein the lifting drive assembly 801 is used to drive the detection column 802 to move up and down.

[0059] The hole entry detection mechanism 8 also includes a sensor that detects the downward flow of the aforementioned detection column.

[0060] The detection column 802 is inserted into the middle bend portion 10 of the pre-bent coil from top to bottom through the opening 12 of the pre-bent coil. Under the support of the leveling support portion 302 on the side bend portion 11 of the pre-bent coil, the detection column 802 is blocked by the middle bend portion 10 of the pre-bent coil and cannot completely descend to the designed lowest point. At this time, the sensor detects the descent of the detection column, which can be used to confirm that the detection column 802 is blocked, and thus identify that the corresponding pre-bent coil 9 is placed on the leveling mold 3.

[0061] In some embodiments, the lifting drive assembly is a lifting drive assembly that uses a cylinder as a power source, and the up and down movement of the piston rod of the cylinder corresponds to the up and down movement of the detection column.

[0062] The sensor is, for example, a magnetic induction limit switch or a roller limit switch that works with the cylinder of the lifting drive assembly.

[0063] For example, a magnetic induction limit switch detects the piston rod position using a non-contact magnetic induction principle and is installed outside the cylinder. A roller-type limit switch, on the other hand, is triggered by mechanical contact and directly detects the position of the extended end of the piston rod.

[0064] In some embodiments, the control system 1 is electrically connected to the corresponding electronic control components of the electronically controlled feeding mechanism 2, the electronically controlled leveling mechanism 4, the electronically controlled unloading mechanism 5, the electronically controlled operating mechanism 7, and the hole-entry detection mechanism 8, so as to control the corresponding mechanisms to perform corresponding actions, and to receive the detection signals of the above-mentioned sensors and make corresponding controls based on the detection signals of the sensors.

[0065] Control system 1 makes corresponding controls based on the detection signals from the sensors. For example, when a pre-bent coil is detected, the system operates normally. When no pre-bent coil is detected: Operation suspended; Alternatively, when the leveling mold without pre-bent coils is moved to the leveling station, the electrically controlled leveling mechanism does not perform leveling stamping.

[0066] 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. No reference numerals in the claims should be construed as limiting the scope of the claims.
