Description

Technical Field

[0001] This utility model relates to the technical field of winding machine equipment, and more specifically, to an I-beam loading mechanism. Background Technology

[0002] Winding machines are indispensable specialized equipment in the electronics, electrical appliance, motor, and transformer manufacturing industries, primarily used for winding various types of coils. With the rapid development of modern industry and the continuous improvement of automation, the working efficiency and winding quality of winding machines have a crucial impact on the final performance and production efficiency of products. Among the many components of a winding machine, the I-beam reel, as the core component for wire support and guidance, directly affects the smoothness and production efficiency of the entire winding process due to its ease of loading and stability. Therefore, the design and optimization of the I-beam reel loading mechanism has always been one of the key research directions in the industry.

[0003] Traditional I-beam loader mechanisms primarily employ a locating pin system on the chuck that engages with locating holes on the I-beam. The mechanical engagement of the locating pin with the locating hole ensures the spindle effectively drives the I-beam to rotate without slippage. This mechanical positioning transmission method is widely used in the industry and can meet basic winding requirements to a certain extent. However, with the development of winding technology, the specifications and materials of I-beams are becoming increasingly diverse, placing higher demands on the adaptability and reliability of the loader mechanism.

[0004] However, the traditional locating pin drive method has several significant drawbacks. First, the locating pin and locating hole are prone to increased clearance due to mechanical wear during long-term use, resulting in decreased transmission accuracy. This can cause the I-beam to wobble and become eccentric during high-speed rotation, affecting winding quality. Second, each size of I-beam requires a corresponding locating hole at a specific position, increasing manufacturing difficulty and cost. Furthermore, changing to different sizes of I-beams often requires adjusting or replacing the locating pin, which is cumbersome and reduces production efficiency. Finally, the locating pin drive method relies on hard contact, which easily generates noise and vibration, potentially damaging the I-beam over time. These problems severely restrict the improvement of winding equipment production efficiency and product quality.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0032] According to an embodiment of the present invention, an I-beam wheel loading mechanism is provided.

[0033] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-6 As shown, the I-beam wheel loading mechanism according to an embodiment of the present utility model includes:

[0034] Base 1, used to support the entire device and fix it on the winding machine;

[0035] The I-beam wheel fixing seat 2 is located on one side of the base 1 and is used to fix it to the base 1 by bolts; the I-beam wheel movable seat 3 is located on the other side of the base 1 and is arranged opposite to the I-beam wheel fixing seat 2; the rotation power assembly 4 is located on one side of the I-beam wheel fixing seat 2 and is used to provide driving force; the drive assembly 9 is located on one side of the I-beam wheel movable seat 3 and is used to adjust the clamping force on the I-beam wheel 11.

[0036] The I-beam loading mechanism also includes a drive shaft 5 that passes through the middle of one side of the I-beam fixed seat 2, and the drive shaft 5 is connected to the output end of the rotary power assembly 4; a passive shaft 8 is provided through the middle of one side of the I-beam movable seat 3, and the passive shaft 8 is used to cooperate with the drive shaft 5 to drive the rotation of the I-beam 11; the axis of the passive shaft 8 coincides with that of the drive shaft 5, and is coaxial with the axis of the central hole of the I-beam 11 to form a concentric transmission structure; a first chuck assembly 7 is provided on the I-beam fixed seat 2 and is fixedly connected to one end of the drive shaft 5, and a second chuck assembly 10 is provided on one side of the drive assembly 9 and is fixedly connected to one end of the passive shaft 8.

[0037] It should be noted that this utility model uses a programmable logic controller (PLC) as the core control unit to realize remote control of the drive motor 401, the knotting motor 604, and the cylinder 902. The control system mainly consists of a PLC, a servo driver, a power supply module, and a human-machine interface.

[0038] The drive motor 401 is connected to the PLC via a servo driver, enabling precise speed and torque control. The PLC can preset different rotation parameters for the I-beam 11 and automatically adjust the motor speed according to the wire type to ensure uniform winding of the wire. The knotting motor 604, also a servo motor, is connected to the PLC via a dedicated servo driver. The PLC can precisely control its rotation angle, position, and speed to achieve precise knotting and positioning of the wire. Operators can set the knotting program through a touchscreen interface. The cylinder 902 is controlled by a solenoid valve, which is directly connected to the PLC output. The PLC can precisely control the cylinder's extension stroke, speed, and pressure to achieve rapid clamping and releasing of the I-beam 11. By setting different pressure parameters, it can adapt to I-beams 11 of different specifications and materials.

[0039] In one embodiment, the first chuck assembly 7 includes a convex chuck seat 701 fixedly connected to one end of the drive shaft 5. A cylindrical groove 702 is provided in the middle of one side of the convex chuck seat 701. A movable chuck 703 is provided in the cylindrical groove 702, and one side of the movable chuck 703 is fixedly connected to the cylindrical groove 702 by several springs 704. An annular friction plate 705 that contacts the I-beam wheel 11 is provided on the outside of one side of the convex chuck seat 701 (in addition, in specific applications, the annular friction plate 705 is a polyurethane friction plate).

[0040] The working principle of the first chuck assembly 7 is as follows: The first chuck assembly 7 is fixedly connected to the drive shaft 5 through the convex chuck seat 701. When loading the I-beam wheel 11, the movable chuck 703 protrudes outward under the action of the spring 704. After the I-beam wheel 11 is placed in position, the movable chuck 703 is pushed into the cylindrical groove 702 and a preload is applied to the I-beam wheel 11. The annular friction plate 705 contacts the side plate of the I-beam wheel 11, using friction to transmit rotational power, replacing the traditional method of using a positioning pin and positioning hole for transmission. This friction transmission method can effectively prevent the I-beam wheel 11 from slipping during rotation. At the same time, the spring 704 ensures the reliability and adaptability of the clamping, and can adapt to the loading requirements of I-beam wheels of different specifications.

[0041] In one embodiment, the second chuck assembly 10 includes a slide cylinder 1001 that passes through the middle of the movable seat 3 of the I-beam wheel. One end of the slide cylinder 1001 is provided with a movable side chuck 1002 that is fixedly connected to one end of the passive shaft 8. The other end of the passive shaft 8 is connected to the inner side of the slide cylinder 1001 through a bearing, and the other end of the slide cylinder 1001 is fixedly connected to the drive assembly 9 through bolts.

[0042] The second chuck assembly 10 works as follows: The second chuck assembly 10 is connected to the movable seat 3 of the I-beam wheel via the slide cylinder 1001. The movable side chuck 1002 is fixedly connected to one end of the driven shaft 8, forming a support structure opposite to the first chuck assembly 7. When the I-beam wheel 11 is loaded into position, the driven shaft 8 is connected to the inner side of the slide cylinder 1001 via a bearing, ensuring that the driven shaft 8 can rotate freely. Simultaneously, the movable side chuck 1002 can move back and forth under the control of the drive assembly 9, achieving clamping or releasing of the I-beam wheel 11. This structural design ensures that the driven shaft 8 and the drive shaft 5 remain coaxial, guaranteeing the concentricity and stability of the I-beam wheel 11 during rotation, effectively reducing vibration and eccentricity of the I-beam wheel 11 during high-speed rotation.

[0043] It should also be noted that, such as Figure 6 As shown, the I-beam wheel 11 of this utility model includes an I-beam wheel body 1101. One side of the outer surface of the I-beam wheel body 1101 is attached to the annular friction plate 705. A first concave portion 1102 that is attached to the movable clamp 703 is provided in the middle of one side of the I-beam wheel body 1101. A second concave portion 1103 that is attached to the movable side clamp 1002 is provided in the middle of the other side of the I-beam wheel body 1101. A through hole is opened on the inner side of the I-beam wheel body 1101 for winding cables. The I-beam wheel 11 is a common technology in this field, and will not be described in detail here.

[0044] In one embodiment, the rotary power assembly 4 includes a drive motor 401 disposed on one side of the top of the I-beam wheel fixing seat 2 (in addition, in a specific application, the drive motor 401 is a servo motor). The output end of the drive motor 401 is provided with a drive wheel 402, and a driven wheel 403 is sleeved on one end of the drive shaft 5. The driven wheel 403 and the drive wheel 402 are connected by a belt 404.

[0045] The working principle of the rotary power assembly 4 is as follows: The rotary power assembly 4 provides initial power through the drive motor 401. The output end of the drive motor 401 drives the drive pulley 402 to rotate, and the rotational force is transmitted to the driven pulley 403 through the belt 404, thereby driving the drive shaft 5 connected to the driven pulley 403 to rotate. This belt drive structure has the functions of shock absorption, noise reduction and overload protection, and at the same time, it is easy to adjust the transmission ratio, and the rotational speed can be adjusted according to different specifications of the I-beam pulley 11 and different winding requirements. When the drive motor 401 starts, the entire transmission system works in concert, so that the drive shaft 5 drives the I-beam pulley 11 to rotate stably, providing uniform power output for wire winding.

[0046] On the other side of the I-beam wheel fixing base 2, a knotting and winding assembly 6 is provided for knotting and winding the wire. The knotting and winding assembly 6 includes a knotting seat 601 connected to the middle of one side of the I-beam wheel fixing base 2. A knotting rotating seat 602 is provided through the middle of one side of the knotting seat 601. A bushing 603 is provided through the middle of one side of the knotting rotating seat 602. A knotting motor 604 is provided at the bottom of one side of the I-beam wheel fixing base 2. The output end of the knotting motor 604 (in actual applications, the knotting motor 604 is a servo motor) is rotatably connected to the outside of the knotting rotating seat 602 through a gear pair to realize the knotting and positioning winding of the wire.

[0047] It should be noted that the knotting rotating seat 602 has a convex structure. Several winding posts are provided on one side of the wide end of the convex structure, and a large toothed ring is fixedly provided on the outer side of the narrow end of the convex structure. A small gear is sleeved on the output end of the knotting motor 604. The large toothed ring and the small gear mesh to form a gear pair, thereby realizing the rotation control of the knotting rotating seat 602.

[0048] In one embodiment, the drive assembly 9 includes a connecting plate 901 fixedly connected to one end of the slide cylinder 1001. A rectangular mounting groove is symmetrically provided on the top and bottom of one side of the I-beam wheel movable seat 3. A cylinder 902 is provided in the rectangular mounting groove (in addition, in specific applications, the cylinder 902 can also be a hydraulic cylinder of the same specification). A mounting plate 903 is provided on one side of the rectangular mounting groove and bolted to the cylinder 902. The output end of the cylinder 902 is fixedly connected to the connecting plate 901.

[0049] The driving assembly 9 works as follows: It is connected to the slide cylinder 1001 via a connecting plate 901. When loading or unloading the I-beam wheel 11, the cylinder 902 extends and retracts under the command of the control system, causing the connecting plate 901 to move back and forth, thereby controlling the clamping or releasing of the movable side clamp 1002 of the second chuck assembly 10 onto the I-beam wheel 11. The cylinder 902 is fixed in the rectangular mounting slot of the movable seat 3 of the I-beam wheel and is bolted to the mounting plate 903, ensuring stable and reliable movement of the cylinder 902. This pneumatic control method offers fast response and simple operation, enabling rapid loading and unloading of the I-beam wheel 11 and improving production efficiency. Simultaneously, the pressure of the cylinder 902 is adjustable, allowing for adjustment of the clamping force according to the material and size of different I-beam wheels 11, ensuring secure clamping without damaging the I-beam wheel 11.

[0050] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0051] In practical applications, the working process of this I-beam loading mechanism is as follows: First, the operator selects the corresponding I-beam specifications and winding parameters via a touchscreen. Then, the PLC system controls the cylinder 902 to retract according to the input parameters, causing the movable seat 3 of the I-beam to move backward, creating space for loading the I-beam 11. The operator places the I-beam 11 on the first chuck assembly 7. At this time, the movable chuck 703 applies a preload to the I-beam 11 under the action of the spring 704, and the annular friction plate 705 contacts the side plate of the I-beam 11. Next, the PLC controls the cylinder 902 to extend, pushing the movable seat 3 of the I-beam to move forward, so that the movable side chuck 1002 of the second chuck assembly 10 contacts the other side of the I-beam 11, forming a bidirectional clamping of the I-beam 11.

[0052] Once the I-beam spool 11 is loaded, the PLC starts the drive motor 401, which, through the drive wheel 402, belt 404, and driven wheel 403, drives the drive shaft 5 and the I-beam spool 11 to rotate. Simultaneously, the PLC controls the knotting motor 604 according to the winding process requirements, which, through a gear pair, drives the knotting rotating seat 602 to rotate, allowing the winding post to work in conjunction with the rotation of the I-beam spool 11 to complete the knotting and winding of the wire. Throughout the process, due to the use of friction drive and a concentric shaft support structure, the rotation of the I-beam spool 11 is more stable, vibration and noise are significantly reduced, and the winding quality is significantly improved.

[0053] After winding is complete, the PLC controls the drive motor 401 and the knotting motor 604 to stop, then controls the cylinder 902 to retract, the I-beam reel movable seat 3 to move backward, releasing the I-beam 11. The operator can then remove the wound I-beam 11 and load a new I-beam 11 to continue production. The entire process is highly automated, easy to operate, and highly adaptable, meeting the needs for rapid loading and efficient winding of I-beam 11 of different specifications, greatly improving production efficiency and product quality.
