Description

Technical Field

[0001] This utility model relates to the field of iron core processing technology, and in particular to a material handling mechanism for a coiling machine. Background Technology

[0002] The iron core is a crucial component of an electric motor, affecting not only its performance but also its production cost. With increasing motor production, the consumption of silicon steel for iron cores is enormous. Coupled with escalating international energy issues and rising steel prices, the technology of coiling and stacking motor iron cores has received widespread attention. During processing, the iron core needs to be coiled in strip form, rotating a straight strip to form a circumferential coil. This strip is then wound along a spiral feeding structure to create a spiral stacked structure. The cutting mechanism in the winding machine cuts the coiled strip to a predetermined thickness, forming a finished disc-shaped iron core. After the disc-shaped iron core is formed, the winding machine needs to be stopped, and workers manually remove the material and then manually restart the winding machine. This process involves long downtime, frequently causing the winding machine to stop, limiting processing speed. Furthermore, direct contact between workers and the finished product leaves impurities on the iron core surface, and the sharp iron core surface can easily cut hands. Ultimately, this leads to decreased production capacity and wasted labor. Utility Model Content

[0003] The purpose of this utility model is to design a material handling mechanism for a winding machine to overcome the shortcomings of the above-mentioned technology.

[0004] This utility model designs a material handling mechanism for a winding machine, including a frame. The frame is provided with a winding station and a preparatory station. The winding station is provided with a winding machine for winding iron core strips into a disc-shaped iron core. The preparatory station can temporarily store the disc as a transfer station. The frame is provided with a material handling mechanism above both the winding station and the preparatory station for grabbing and transferring the disc. The material handling mechanism includes a mounting plate slidably connected to the frame. The mounting plate is provided with two first driving members. The output ends of the two first driving members extend downward to above the winding station and the preparatory station, respectively. The output end of each first driving member is provided with a gripping robot.

[0005] Preferably, the frame is provided with a slide rail above the winding station and the preparation station, the bottom of the mounting plate is provided with a slider that slides with the slide rail, and the frame is provided with a linear cylinder, the output end of the linear cylinder is connected to the mounting plate to drive the mounting plate to reciprocate along the slide rail.

[0006] Further optimization involves two first driving components arranged side-by-side on the mounting plate, with the slide rail located on both sides of the mounting plate and the linear cylinder located in the middle of the mounting plate. The two first driving components are symmetrically distributed on the mounting plate with the linear cylinder position as the center. The fixed end of the first driving component is connected to the mounting plate, and the output end of the first driving component extends downward and can perform lifting and lowering actions.

[0007] In a further optimization, the output end of the first driving component is also provided with a connecting plate. The connecting plate moves up and down with the output end of the first driving component. The connecting plate is provided with a guide hole. The frame is also provided with a guide rod. The guide rod corresponds one-to-one with the first driving component. One end of the guide rod is fixed to the frame, and the other end is slidably connected in the guide hole to guide the output end of the first driving component to move up and down.

[0008] Preferably, the robotic arm includes a second driving member installed at the output end of the first driving member. The output end of the second driving member is provided with three grippers. The three grippers are circumferentially distributed and slidably connected to the output end of the second driving member. The three grippers slide back and forth under the drive of the second driving member to form a gripping and releasing action.

[0009] Further optimization involves the gripper comprising an L-shaped block structure, one end of which is connected to the output end of the second drive unit, and the other end is positioned downwards with a protrusion on its outer side. The outward-facing surface of the gripper is an outwardly convex arc surface.

[0010] Further optimization involves providing a silicone buffer layer on the outer convex arc surface of the gripper.

[0011] The technical advantage of this invention is that the frame is equipped with parallel winding stations and preparation stations, and robotic arms are installed above both stations. The two robotic arms are mounted on the same mounting plate to achieve synchronous movement. The robotic arms grab and transfer the finished material disc-shaped iron cores on the two stations. That is, the two synchronously operating robotic arms grab and transfer the finished material disc-shaped iron cores on the winding station and the preparation station at the same time. The finished material disc-shaped iron cores on the preparation station can be transferred from the finished material disc-shaped iron cores on other winding stations. Therefore, a staggered grabbing and transfer is formed, which is not only flexible and efficient, but also avoids directly holding the finished material disc-shaped iron cores by hand.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0018] This utility model includes a frame 1, on which a winding station 2 and a preparatory station 3 are provided, the winding station 2 and the preparatory station 3 being arranged side by side.

[0019] The winding station 2 is equipped with a winding machine 4 for winding the strip into a tray. The winding machine 4 winds the iron core strip into a tray-shaped iron core, and cuts it after a certain degree of winding to form a finished tray-shaped iron core. The preparatory station 3 can temporarily store the tray as a transfer station. The frame 1 is equipped with a material picking mechanism 5 above both the winding station 2 and the preparatory station 3 for picking up and transferring the tray. The material picking mechanism 5 includes a mounting plate 6 slidably connected to the frame 1. The mounting plate 6 is equipped with two first driving members 7. The output ends of the two first driving members 7 extend downward to the top of the winding station 2 and the preparatory station 3, respectively. The output end of each first driving member 7 is equipped with a gripping robot 8, that is, the two first driving members 7 move synchronously back and forth with the mounting plate 6.

[0020] In use, for example, the winding station 2 and the standby station 3 in the material handling mechanism 5 of the winding machine are grouped together. After the two groups are placed side by side in opposite directions, they form a grid pattern. The two winding stations 2 are diagonally opposite each other, and the two standby stations 3 are diagonally opposite each other. When the mounting plate 6 moves, the robotic arms 8 of the two first drive components 7 grab the finished material disc-shaped iron core on one side of the winding station 2 and transfer it to the standby station 3 on the other side. At this time, the robotic arm 8 of the other first drive component 7 moves from the standby station 3 on the same side to the winding station 2 on the other side to grab it, waiting for the mounting plate 6 to move again. That is, a staggered grabbing and transfer is formed. In this way, the finished material disc-shaped iron core on the winding station 2 can be transferred to the standby station 3 for standby. The whole process is very flexible. It can avoid directly holding the finished material disc by hand and can temporarily store and transfer the finished material disc at multiple stations, which improves the efficiency of the entire transfer process and avoids the extra return time caused by the linear transfer.

[0021] After the robotic arm 8 removes the finished disc-shaped iron core, the winding machine 4 can start and wind the next iron core strip. During this process, the robotic arm 8 can move the finished disc-shaped iron core out of the winding machine 4 and place it on the conveyor belt or another preparatory station 3. The conveyor belt can be directly connected to the subsequent automated process, or it can be placed at the preparatory station 3 for manual handling. When the robotic arm 8 returns to directly above the winding machine 4, the winding machine 4 has already wound half of the core. Throughout the entire process, the winding machine 4 only needs to stop for a few seconds, and can start again after the robotic arm 8 removes the finished disc-shaped iron core. The process does not require stopping the machine; the only delay is the few seconds spent transferring the core to the preparatory station 3. This improves the overall processing speed, reduces the number of personnel, and ensures the cleanliness of the finished disc-shaped iron core by ensuring that no personnel directly contact it.

[0022] Furthermore, the frame 1 is provided with a slide rail 9 above the winding station 2 and the preparation station 3. The bottom of the mounting plate 6 is provided with a slider 10 that slides with the slide rail 9. The frame 1 is provided with a linear cylinder 11. The output end of the linear cylinder 11 is connected to the mounting plate 6 to drive the mounting plate 6 to reciprocate along the slide rail 9. In this embodiment, two first driving members 7 are arranged side by side on the mounting plate 6. The slide rail 9 is located on both sides of the mounting plate 6, that is, both sides of the mounting plate 6 are provided with slide rail 9. The linear cylinder 11 is located in the middle of the mounting plate 6. The extension and retraction direction of the linear cylinder 11 is set in the same direction as the slide rail 9. The extension and retraction end of the linear cylinder 11 is connected to the mounting plate 6, pushing the mounting plate 6 to reciprocate along the slide rail 9.

[0023] Two first drive components 7 are symmetrically distributed on the mounting plate 6 around the center of the linear cylinder 11. The fixed end of the first drive component 7 is connected to the mounting plate 6, and the output end of the first drive component 7 extends downward and can perform lifting and lowering actions, making the reciprocating movement more stable.

[0024] Furthermore, the robotic arm 8 includes a second driving member 14 installed at the output end of the first driving member 7. The second driving member 14 moves up and down with the first driving member 7. The output end of the second driving member 14 is provided with three grippers 15. The three grippers 15 are located at the lowest end of the second driving member 14 and are circumferentially distributed at the output end of the second driving member 14. A circumferentially distributed sliding groove is opened on the output end of the second driving member 14. The three grippers 15 are L-shaped block structures. A straight part of the gripper 15 is slidably connected to the sliding groove through a sliding block, so that the three grippers 15 are correspondingly slidably connected in the sliding groove. Under the drive of the second driving member 14, the three grippers 15 can synchronously reciprocate to form a gripping and releasing action.

[0025] It should be noted that the other straight section of the gripper 15 is vertically downward. An integrated protrusion is located on the outer side of the downward-facing end of this straight section. The finished product tray on the winding machine 4 is suspended in mid-air. After the three grippers 15 retract, they move to the central hollow area of ​​the finished product tray. When the bottom of the grippers 15 descends to below the finished product tray core, the three grippers 15 slide open, and the outer side of the vertical section of the grippers 15 abuts against the inner wall of the finished product tray core. That is, the three grippers 15 are evenly abutted against the inner wall of the finished product tray core in a circumferential direction. The three grippers 15 are driven upward by the first driving member 7. At this time, the protrusion of the gripper 15 is engaged with the bottom of the finished product tray core. As the grippers 15 continue to rise, the finished product tray core is carried away from the winding machine 4, realizing the gripping and transfer of the finished product tray core.

[0026] Furthermore, the outer surface of the vertical part of the gripper 15 is a convex arc surface 17 to adapt to the annular inner wall of the finished product tray, and a silicone buffer layer is provided on the convex arc surface 17 so that the silicone buffer layer can directly contact the inner wall of the finished product tray iron core, avoiding damage to the finished product tray iron core or deformation of the finished product tray iron core during gripping.

[0027] Furthermore, the output end of the first driving component 7 is also provided with a connecting plate 12. The connecting plate 12 moves up and down with the output end of the first driving component 7. The connecting plate 12 is provided with a guide hole. The frame 1 is also provided with a guide rod 13. The guide rod 13 corresponds one-to-one with the first driving component 7. One end of the guide rod 13 is fixed to the frame 1, and the other end is slidably connected in the guide hole to guide the output end of the first driving component 7 to move up and down. The first driving component 7 is also provided with a buffer. Through the combined action of the buffer and the guide rod 13, the output end of the first driving component 7 can move up and down stably.

[0028] The first driving component 7 and the second driving component 14 mentioned above can be a cylinder, a hydraulic cylinder or a motor.

[0029] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
