Description

Technical Field

[0001] This utility model belongs to the technical field of power cord processing equipment, specifically a fully automatic power cord tying machine. Background Technology

[0002] Power cords, as key components in electronic devices and home appliances, require neat bundling during production, warehousing, and shipping to prevent tangling, damage, or excessive space occupation. Existing wire tying machines are primarily used for automated winding and bundling of power cords. By replacing manual operation with mechanical structures, they significantly improve bundling efficiency and ensure the consistency and standardization of wire bundling. These machines are widely used in the electronics manufacturing and home appliance assembly industries, playing a crucial supporting role in promoting large-scale production in these sectors.

[0003] Currently, common wire tying machines still have room for improvement in the coordinated action of winding and binding. In some machines, the extension and retraction of the winding rod and the binding action require separate control by multiple drive mechanisms, which can easily lead to timing discrepancies. Furthermore, the design of the contact points between the winding rod and the wire has limited adaptability to wires of different diameters, potentially affecting the stability of the winding. In addition, in the structural layout of some machines, the spatial fit between the transmission components and the binding mechanism is not compact enough, increasing the complexity of equipment debugging and maintenance to some extent. Summary of the Invention

[0004] To address the problems mentioned in the background section, this invention provides a fully automatic power cord tying machine to solve the problems of poor coordination between tying and loosening of wires and low efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fully automatic power cord tying machine, characterized in that it includes a frame, a winding unit, and a tying unit. The frame is configured as a frame structure consisting of a base, a top plate, and columns. The winding unit is fixed to the center of the upper surface of the base. The winding unit includes a winding disc and several elastic telescopic winding rods. The telescopic winding rods are perpendicular to the axis of the winding disc and are evenly distributed along the edge of the winding disc. Each telescopic winding rod includes a fixed sleeve welded to the upper surface of the winding disc and a sliding... The movable rod is inserted into the fixed sleeve, and the return spring is sleeved between the bottom end of the fixed sleeve and the bottom end of the movable rod. The top end of the movable rod is welded with a circular connecting block. The cable tie unit includes a lifting mechanism, a pressure head, several connecting rods, and a cable tie machine. The lifting mechanism is installed on the upper surface of the top plate and its output end penetrates through the top plate. The pressure head is fixed on the bottom output end of the lifting mechanism. The connecting rod is hinged to the lower surface of the pressure head and its position corresponds to the telescopic winding rod. The other end of the connecting rod is tilted downward and rotatably connected to the circular connecting block. The cable tie machine is fixed to the lower surface of the pressure head and located between the connecting rods.

[0006] Optionally, it also includes a drive unit, which is a servo motor fixed to the center of the upper surface of the base. The output shaft of the servo motor is vertically upward and engages with the central through hole of the winding disc. The servo motor drives the winding disc to rotate around the vertical axis, thereby realizing the winding of the power cord at the exposed end of the movable rod.

[0007] Optionally, the top of the movable rod is configured as a concave round head adapted to the power cord, and the outer surface of the concave round head is provided with anti-slip texture.

[0008] Optionally, the cable tie machine's binding contact faces the outer side of the telescopic winding rod corresponding to the winding reel, and the outer side of the winding reel is welded with an annular receiving groove for receiving the power cord that has been loosened after binding.

[0009] Optionally, the radial retraction stroke of the movable rod is 20-30mm, the elastic coefficient of the return spring is 1.5-5N / mm, and it is compatible with power cords with a diameter of 0.5-10mm.

[0010] Optionally, the cable tie machine integrates feeding and cutting functions, and the downward stroke of the binding contact and the retraction stroke of the movable rod are matched in sequence to ensure that the movable rod retracts synchronously to loosen the cable tie after it is in place.

[0011] Optionally, the angle between the connecting rod and the vertical direction is 30°-45°.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In this invention, when the lifting platform's output end drives the pressure head to move vertically downwards, the connecting rod hinged to the lower surface of the pressure head moves downwards accordingly. Because the connecting rod is tilted at 30°-45° and its other end is rotatably connected to the circular connecting block of the movable rod, the vertical downward force is converted into a radial pulling force along the movable rod (pointing towards the center of the winding coil), pulling the movable rod inwards along the fixed sleeve. Simultaneously, the cable tie machine on the lower surface of the pressure head moves downwards synchronously with the pressure head, and its binding contact contacts the winding coil to complete the binding. This linkage process allows "cable tie placement" and "moving rod retraction and loosening of the wire" to be completed through the same power source, eliminating the need for additional control and coordination, ensuring seamless action transitions, and improving operational continuity. In this invention, a fixed sleeve is welded to the winding reel to provide fixed support, and a movable rod is slidably inserted into the fixed sleeve. The two ends of a return spring abut against the bottom of the fixed sleeve and the bottom of the movable rod, respectively. During winding, the power cord is wound around the top of the movable rod. As the diameter of the winding coil increases, the cord will press against the movable rod towards the center of the winding reel, forcing the movable rod to compress the return spring and contract inward. The spring's reaction force acts in the opposite direction on the cord, creating tension matching the cord diameter to ensure neat and non-loose winding. After unwinding, the lifting mechanism moves the pressure head upward, and the spring force pushes the movable rod back to its initial position, preparing it for the next winding, adapting to the winding needs of power cords with different diameters. In this invention, the cable tie machine is fixed to the lower surface of the pressure head and located between the connecting rods, avoiding interference with the movement of the connecting rods; the concave round head at the top of the movable rod conforms to the shape of the power cord, and the anti-slip texture reduces the slippage of the wire and reduces the risk of scratching the insulation layer; the annular receiving groove on the outside of the winding reel directly receives the loosened cable tie after the movable rod retracts, reducing the wire falling or tangling during material handling, and the overall structure is adapted to the operation rhythm of continuous production.

[0014] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figures 1 to 4As shown, this utility model provides a fully automatic power cord tying machine, characterized in that it includes a frame, a winding unit, and a tying unit. The frame is configured as a frame structure consisting of a base 1, a top plate 2, and columns. The winding unit is fixedly mounted on the center of the upper surface of the base 1. The winding unit includes a winding disc 3 and several elastic telescopic winding rods 4. The telescopic winding rods 4 are perpendicular to the axis of the winding disc 3 and are evenly distributed along the edge of the winding disc 3. Each telescopic winding rod 4 includes a fixed sleeve 5 welded to the upper surface of the winding disc 3, a movable rod 6 slidably inserted into the fixed sleeve 5, and a sleeved on the fixed sleeve 3. A return spring 7 is located between the bottom end of the fixed sleeve 5 and the bottom end of the movable rod 6. A circular connecting block 8 is welded to the top end of the movable rod 6. The cable tie unit includes a lifting machine 9, a pressure head 10, several connecting rods 11, and a cable tie machine 12. The lifting machine 9 is installed on the upper surface of the top plate 2 and its output end passes through the top plate 2. The pressure head 10 is fixed on the bottom output end of the lifting machine 9. The connecting rod 11 is hinged to the lower surface of the pressure head 10 and the position of the connecting rod 11 corresponds to the telescopic winding rod 4. The other end of the connecting rod 11 is inclined downward and rotatably connected to the circular connecting block 8. The cable tie machine 12 is fixed to the lower surface of the pressure head 10 and located between the connecting rods 11.

[0016] Specifically, the linkage structure of the lifting platform 9, the pressure head 10, and the connecting rod 11 enables the synchronous action of cable ties and wire loosening: when the output end of the lifting platform 9 drives the pressure head 10 to move vertically downward, the connecting rod 11 hinged to the lower surface of the pressure head 10 moves downward accordingly. Since the connecting rod 11 is tilted at 30°-45° and its other end is rotatably connected to the annular connecting block 8 of the movable rod 6, the vertical downward force is converted into a radial pulling force along the movable rod 6, pulling the movable rod 6 to retract inward along the fixed sleeve 5; at the same time, the cable tie machine 12 on the lower surface of the pressure head 10 moves downward synchronously with the pressure head 10, and its binding contact contacts the coil to complete the binding. This linkage process allows the "cable tie in place" and the "movable rod 6 retracting and loosening the wire" to be completed through the same power source, without the need for additional control and coordination, and the action connection is seamless, improving the continuity of the operation.

[0017] It also includes a drive unit, which is a servo motor 13 fixed to the center of the upper surface of the base 1. The output shaft of the servo motor 13 is vertically upward and is engaged with the center through hole of the winding disk 3. The servo motor 13 drives the winding disk 3 to rotate around the vertical axis, so as to realize the winding of the power line at the exposed end of the movable rod 6.

[0018] Specifically, the flexible telescopic winding rod 4 has a matching structure that adapts to the wire diameter and maintains winding tension: the fixed sleeve 5 is welded to the winding reel 3 to provide fixed support, the movable rod 6 is slidably inserted into the fixed sleeve 5, and the two ends of the return spring 7 abut against the bottom of the fixed sleeve 5 and the bottom of the movable rod 6, respectively. During winding, the power cord is wound around the top of the movable rod 6. As the diameter of the winding coil increases, the wire will squeeze the movable rod 6 towards the center of the winding reel 3, forcing the movable rod 6 to compress the return spring 7 and contract inward. The reaction force of the spring acts in the opposite direction on the wire, forming a tension force that matches the wire diameter, ensuring that the winding is neat and not loose. After the wire is unwound, the lifting platform 9 drives the pressure head 10 to move upward, and the spring force pushes the movable rod 6 back to the initial position, preparing for the next winding and adapting to the winding needs of power cords with different diameters.

[0019] The top of the movable rod 6 is set with a concave round head to adapt to the power cord, and the outer surface of the concave round head is provided with anti-slip texture.

[0020] The cable tie machine 12 has its binding contact facing the outside of the telescopic winding rod 4 and the corresponding winding reel 3. The outside of the winding reel 3 is welded with an annular receiving groove 14 for receiving the power cord that has been loosened after binding.

[0021] Specifically, the compact layout and detailed design enhance operational smoothness: the cable tie machine 12 is fixed to the lower surface of the pressure head 10 and located between the connecting rods 11, avoiding interference with the movement of the connecting rods 11; the concave round head at the top of the movable rod 6 conforms to the shape of the power cord, and the anti-slip texture reduces the slippage of the wire, while also reducing the risk of scratching the insulation layer; the annular receiving groove 14 on the outer side of the winding reel 3 directly receives the loosened cable tie after the movable rod 6 retracts, reducing the wire from falling or tangling during material handling, and the overall structure is adapted to the operation rhythm of continuous production.

[0022] The radial retraction stroke of the movable rod 6 is 20-30mm, the elastic coefficient of the return spring 7 is 1.5-5N / mm, and it is compatible with power cords with a diameter of 0.5-10mm.

[0023] The cable tie machine 12 integrates feeding and cutting functions. The downward stroke of the binding contact is matched with the retraction stroke of the movable rod 6 to ensure that the movable rod 6 retracts synchronously to loosen the cable tie after it is in place.

[0024] The angle between the connecting rod 11 and the vertical direction is 30°-45°.

[0025] The working principle and usage process of this utility model are as follows: After starting the equipment, the servo motor 13 drives the winding reel 3 to rotate around the vertical axis. The power cord is wound around the top of the movable rod 6. As the diameter of the winding coil increases, the wire squeezes the movable rod 6 and contracts along the fixed sleeve 5 towards the center of the winding reel 3. The return spring 7 is compressed, generating a reverse elastic force to keep the wire taut. After winding is completed, the lifting platform 9 drives the pressure head 10 to move vertically downward. The connecting rod 11 on the lower surface of the pressure head 10 moves downward accordingly. Because the connecting rod 11 is inclined and connected to the circular connecting block 8, the vertical force is converted into radial tension, pulling the movable rod 6 to contract further. At the same time, the cable tie machine 12 on the lower surface of the pressure head 10 moves downward synchronously, and its contact contacts the coil to complete the binding. After the binding is completed, the lifting platform 9 drives the pressure head 10 to move upward, the return spring 7 pushes the movable rod 6 to return to its original position, and the loosened wire falls into the receiving groove 14 on the outside of the winding reel 3. The worker can then pick up the material to complete one operation.
