Description

Technical Field

[0001] The invention relates to the technical field of transformer core manufacturing, in particular to transformer core production equipment. Background Art

[0002] Before preparing the transformer core, long silicon steel strips need to be cut and bent into shaped strip frames (upper and lower strip frames) for stacking. In the past, manual intervention was required in each process of core production (including stacking the shaped strip frames), which was time-consuming and labor-intensive, resulting in low production efficiency and difficulty in ensuring quality.

[0003] In the process of producing iron cores, how to stack the molding strip frames is a key factor restricting the improvement of production efficiency. The invention patent with authorization announcement number CN108987090B discloses a folding iron core automatic material sorting machine, which introduces a material sorting device that automatically stacks the molding strip frames. However, in the actual production process, it was found that the device still has some shortcomings that need to be improved:

[0004] 1. To improve stacking efficiency, the first and second robotic arms are used to alternately pick up the formed material strip frames. However, the two robotic arms are used independently, which takes up a lot of space, has poor integration, high operating costs, and is inconvenient to retrieve materials.

[0005] 2. Even if dual robotic arms are used to alternately pick up the formed material strip frames, the machine still needs to be stopped to unload the materials after stacking is completed, which cannot maximize the stacking efficiency. Summary of the Invention

[0059] Example 1: Figures 1-8 The transformer core production equipment shown is used to produce foldable open transformer cores, including a strip frame forming machine 100, a manipulator assembly truss 200, a strip frame stacking assembly 300 and a roller conveyor 400. The strip frame forming machine 100 is provided with a discharge port for sequentially discharging the silicon steel strip after bending and forming. The manipulator assembly truss 200 includes a transverse guide rail 210 and a frame 220. The transformer core production equipment also includes a cross-type unloading manipulator 500. The strip frame stacking assembly 300 is provided with a roller conveyor 400. 0 is provided with a pair, and each is assembled on a fixed base 700 through a rotating platform 600. The strip frame forming machine 100 is centrally fixed between the pair of strip frame stacking assemblies 300. The cross-type unloading robot 500 can grab the molding strip frame 800 from the discharge port 110 of the strip frame forming machine 100 and alternately place the molding strip frame 800 on the pair of strip frame stacking assemblies 300. The strip frame stacking assemblies 300 are used to transfer the stacked molding strip frames 800 to the roller conveyor 400;

[0060] Combine Figure 4 and Figure 5As shown, the cross-type material feeding manipulator 500 includes a moving component 510, an attitude adjustment component 520, and a grasping component 530. The moving component 510 includes a sliding seat 511, a motor on the sliding seat 512, and a boom support 513. The sliding seat 511 is assembled on the manipulator assembly truss 200 and can be driven by the motor on the sliding seat 512 to reciprocate linearly between a pair of strip frame stacking components 300. The upper end of the boom support 513 is fixedly assembled on the sliding seat 511;

[0061] The attitude adjustment component 520 includes a pair of hollow rotating seats symmetrically arranged with respect to the boom support 513, namely a left rotating seat 521 and a right rotating seat 522. The lower end of the boom support 513 is fixedly connected in the middle between the left rotating seat 521 and the right rotating seat 522. The left rotating seat 521 is equipped with a left robotic arm 523, and the left robotic arm 523 can be rotated to a horizontal position or a vertical position through the left rotating seat 521. The right rotating seat 522 is equipped with a right robotic arm 524, and the right robotic arm 524 can be rotated to a vertical position or a horizontal position through the right rotating seat 522;

[0062] The grasping component 530 is installed on both the left robotic arm 523 and the right robotic arm 524, and the grasping component 530 is used to grasp the formed strip frame 800.

[0063] The grasping component 530 includes a suction cup mounting seat 531, a pneumatic push rod 532, and a vacuum suction cup 533. The vacuum suction cups 533 are evenly arranged at the bottom of the suction cup mounting seat 531, and the formed strip frame 800 can be controlled to be put down through the pneumatic push rod 532. The grasping component 530 is assembled on the left robotic arm 523 and the right robotic arm 524 through the connection end of the suction cup mounting seat 531 and can slide independently along the left robotic arm 523 and the right robotic arm 524.

[0064] In this embodiment, both the left robotic arm 523 and the right robotic arm 524 include a module base 525, a double-channel guide rail 526, a sliding block 527, and a module motor 528. The module base 525 is used to set the double-channel guide rail 526. The module motor 528 is arranged in the module base 525 and is used to drive the sliding block 527 to reciprocate along the double-channel guide rail 526. The suction cup mounting seat 531 is bolted and assembled on the sliding block 527.

[0065] As Figure 9 shown, the shape of the formed strip frame 800 is in an "L" shape. The present invention can grasp the upper top surface 810 of the formed strip frame 800 through the vacuum suction cup 533 and then stack them one by one in a posture with the opening facing downwards.

[0066] Specifically, in combination with Figure 1As shown, first, the long silicon steel strip is conveyed from the uncoiler 120 to the strip frame forming machine 100, and the bent formed strip frame 800 is output from the discharge port 110 of the folding strip frame forming machine 100 (at this time, the upper top surface 810 of the formed strip frame 800 faces outward), and the arm bracket 513 is moved so that the left mechanical arm 523 of the hollow rotating seat is moved to the specified position, and the right mechanical arm 524 is moved to the specified position (as shown in FIG. Figure 3 and Figure 4 As shown in FIG5 , the sliding seat 511 above the boom bracket 513 slides laterally along the transverse guide rail 210 of the manipulator assembly truss 200 driven by the motor 512 on the sliding seat. When the vacuum suction cup 533 of the left manipulator 523 grabs the molding strip frame 800, it contacts the upper top surface 810 of the molding strip frame 800. During the movement of the boom bracket 513, the vacuum suction cup 533 drives the molding strip frame 800 to slide upward and rotate to the top of the strip frame stacking assembly 300. The suction cup mounting seat 531 slides downward along the double-track guide rail 526. At the same time, the pneumatic push rod 532 is used to push the molding strip frame 800 upward. Push the upper top surface 810 of the molding material strip frame 800 to open the two side surfaces 820 of the molding material strip frame 800 and place it toward the material strip frame stacking assembly 300. Then, inflate the vacuum suction cup 533 to quickly separate it from the molding material strip frame 800. At the same time, the vacuum suction cup 533 of the left robotic arm 523 rotates from vertical to horizontal. At the same time, the vacuum suction cup 533 of the right robotic arm 524 contacts the upper top surface 810 of the molding material strip frame 800 output by the material strip frame molding machine 100 in the horizontal direction, slides and rotates to a vertical state, and moves the boom bracket 513 to make the left robotic arm 523 rotate from vertical to horizontal. Figure 2 Medium stance to Figure 3 After the posture is achieved, the above steps are repeated to complete the stacking of a specified number of molding strip frames 800.

[0067] Combine Figure 6 and Figure 7 As shown, in this embodiment, the strip frame stacking assembly 300 includes a stacking seat 310, a material support and a transition frame, wherein:

[0068] The material support includes a pair of first limiting supports 320 that are centrally fixed on the rotating platform 600 and can move toward or away from each other. The two ends of the first limiting supports 320 form a first support 321 for receiving the molding material strip frame 800 placed by the cross-type unloading robot 500;

[0069] The transition frame includes a first docking frame 330 disposed between the first limiting bracket 320 and the edge of the rotating platform 600. The bottom of the first docking frame 330 is mounted on the rotating platform 600 via a rotating seat 331, and a frame drive motor 332 is connected via the rotating seat 331. The first docking frame 330 can be switched between a vertical position and a horizontal position under the drive of the frame drive motor 332.

[0070] The stacking base 310 includes a first base 311 fixedly connected to the inner side of the first docking frame 330, a first telescopic rod 312 disposed in the first base 311, and a first placement plate 313 fixed to the top of the first telescopic rod 312. The first placement plate 313 is located between the first support platforms 321 of a pair of first limiting brackets 320.

[0071] When the first docking frame 330 is rotated to a vertical position, its top is higher than the horizontal height of the top of the first limiting bracket 320; when the first docking frame 330 is rotated to a horizontal position, its top is docked with the roller conveyor 400 and can transfer the stacked molding material strip frame 800 to the roller conveyor 400 under the push of the first placement plate 313.

[0072] It is worth mentioning that before starting work, the spacing of the first limiting bracket 320 can be adjusted according to the width of the molding material strip frame 800. The first docking frame 330 is in a vertical position, and the stacking seat 310 is located between the first limiting bracket 320. The first placement plate 313 and the first support 321 are located on the same horizontal plane to better support the molding material strip frame 800. When the molding material strip frame 800 is stacked, it is only necessary to rotate the first docking frame 330 from a vertical position to a horizontal position while gradually pushing out the first placement plate 313, so that the stacked molding material strip frame 800 leans against the first docking frame 330 and is finally pushed onto the roller conveyor 400.

[0073] During the process of the cross-type material discharge robot 500 lowering the molding material strip frame 800, the pneumatic push rod 532 is used to push the upper top surface 810 of the molding material strip frame 800, so that the two side surfaces 820 of the molding material strip frame 800 are opened and descend along the outer side of the first limiting bracket 320 until the upper top surface 810 of the molding material strip frame 800 contacts the first placement plate 313 or contacts the upper top surface 810 of the molding material strip frame 800 placed on the first placement plate 313.

[0074] In some embodiments, the transverse guide rail 210 is horizontally fixed on the frame 220 , and the transverse guide rail 210 allows the sliding seat 511 to move linearly between the two rotating platforms 600 .

[0075] It should be noted that in the present invention, when the left robotic arm 523 is in a vertical position, the grabbing assembly 530 on the left robotic arm 523 places the molding strip frame 800, while the right robotic arm 524 is in a horizontal position, and the grabbing assembly 530 on the right robotic arm 524 grabs the molding strip frame 800;

[0076] When the left robotic arm 523 is in the horizontal position, the grasping component 530 on the left robotic arm 523 performs the action of grasping the formed tape frame 800. At the same time, the right robotic arm 524 is in the vertical position, and the grasping component 530 on the right robotic arm 524 performs the action of placing the formed tape frame 800.

[0077] To adapt to different working heights, as an improvement of the technical solution, as Figures 1 to 3 shown, liftable floor legs 710 are provided at the bottom of both the fixed base 700 and the roller conveyor 400.

[0078] Embodiment 2: The difference from the above Embodiment 1 is that in this embodiment, the material support further includes a pair of second limiting brackets 340 that are perpendicularly and crosswise arranged with the first limiting bracket 320. Both ends of the second limiting bracket 340 have second support platforms 341 that are equal in height to the first support platform 321, and a让位滑槽342 for the first limiting bracket 320 to move is provided on the second limiting bracket 340;

[0079] The transition frame further includes a second docking frame 350 provided between the second limiting bracket 340 and the edge of the rotary platform 600. Thus, the second docking frame 350 and the first docking frame 330 form a square planar structure. The second docking frame 350 is rotatably mounted on the rotary platform 600, and when the second docking frame 350 is driven to rotate, it can switch between the vertical position and the horizontal position;

[0080] The stacking base 310 further includes a second base 314 fixedly connected to the inside of the second docking frame 350. The second base 314 is provided with a second telescopic rod 315 and a second placement plate 316 fixed to the top of the second telescopic rod 315;

[0081] When the second docking frame 350 rotates to the vertical position, its top is higher than the horizontal height where the top of the second limiting bracket 340 is located; when the second docking frame 350 rotates to the horizontal position, its top is docked with the roller conveyor 400 and can transfer the stacked formed tape frames 800 to the roller conveyor 400 under the push of the second placement plate 316;

[0082] The rotary platform 600 rotates ninety degrees each time to enable the first limiting bracket 320 and the second limiting bracket 340 to alternately receive the formed tape frames 800 placed by the cross-type material placing manipulator 500.

[0083] In this embodiment, in order to further achieve a "fully non-stop" production process and maximize the stacking efficiency, the above cross-type design of the tape frame stacking component 300 is carried out, which is particularly suitable for the formed tape frame 800 with a "C" shape;

[0084] In this embodiment, when the strip frame stacking assembly 300 pushes a set of stacked molding strip frames 800 onto the roller conveyor 400, the cross-type unloading robot 500 is dynamically coupled with the rotating platform 600, so that the cross-type unloading robot 500 can continue to unload the molding strip frames 800 into the strip frame stacking assembly 300 without changing the rhythm, thereby achieving zero-interval unloading.

[0085] It is worth noting that during the unloading process, when the molding material belt frame 800 is moving downward, the rotating platform 600 should be kept in a stationary state through timing control. That is, the rotation of the rotating platform 600 should not be performed during the unloading process, otherwise it may cause interference.

[0086] In addition, the dynamic coordination of the cross-type material discharge robot 500, the rotating platform 600 and the material strip frame stacking assembly 300 in the present invention also requires the control of the electrical control cabinet 900 and the parameter setting of the operation terminal 910 (including but not limited to the moving speed of the cross-type material discharge robot 500, the rotation interval time of the rotating platform 600 and the discharge speed of the molding material strip frame 800).

[0087] In this embodiment, the first docking frame 330 and the second docking frame 350 both include a centrally arranged frame support column 351, and symmetrically and evenly arranged on both sides of the frame support column 351 are limit bars 352 for supporting the sides of the molding strip frame 800;

[0088] The first base 311 is centrally fixed inside the frame support column 351 of the first docking frame 330 , and the second base 314 is centrally fixed inside the frame support column 351 of the second docking frame 350 .

[0089] Through the above structure, the stability during the unloading process can be improved, which is conducive to the smooth lowering of the molding strip frame 800.
