[Specific implementation method] In order to make the technical problems, technical solutions and beneficial effects solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0018] See also Figures 1 to 6 An automatic stringing device includes a winding device 1 for producing coil cores, a stringing device 2 for collecting the coil cores in strings, and a material guide conveyor belt 3 for transferring the coil cores produced by the winding device 1 to the stringing device 2, wherein the stringing device 2 includes a stringing frame 21, a guide rod assembly 22 arranged on the stringing frame 21, and a releasing assembly 23 for releasing the coil cores to the guide rod assembly 22.

[0019] The present application discloses an automatic stringing device and process thereof, which realizes the continuous automated operation of coil cores from output to collection in strings through an automated winding device, a stringing device and a material guide conveyor belt, which not only improves production efficiency, but also significantly improves the consistency of product quality. The winding device can stably produce coil cores, the material guide conveyor belt can accurately transfer the coil cores to the stringing device, and the guide rod assembly and release assembly in the stringing device can efficiently collect the coil cores in strings, avoiding problems such as extrusion, rupture, and scratches that may be caused by manual operation, thereby ensuring product quality while also improving production safety and reliability.

[0020] Furthermore, as a preferred embodiment of the present invention but not a limitation, the release assembly 23 includes a climbing conveyor belt 231 for transporting the coil core to the top of the guide rod assembly 22, a telescopic cylinder 232 located at the end of the climbing conveyor belt 231 and arranged parallel to the climbing conveyor belt 231, and a limit baffle 233 connected to the output end of the telescopic cylinder 232.

[0021] In this embodiment, the climbing conveyor belt 231 smoothly lifts the coil magnetic core to the top of the guide rod assembly 22, ensuring that the magnetic core will not be damaged by collision or friction during the transfer process and reaches the required height of the string rod. The telescopic cylinder 232 located at the end of the climbing conveyor belt 231 ensures the movement of the limit baffle 233 in the corresponding direction to achieve the limit and release of the coil magnetic core through its parallel arrangement. Sensors can also be set on the climbing conveyor belt 231 to monitor the position and state of the coil magnetic core in real time, so as to adjust the speed of the conveyor belt in time or stop the conveyor belt to ensure that the magnetic core can accurately reach the specified position.

[0022] Furthermore, as a preferred embodiment of the present invention but not a limitation, it also includes a guide mechanism 4, a guide port 2331 is provided on the limit baffle 233, and the guide mechanism 4 includes a guide base 41 provided at the end of the climbing conveyor belt 231, a guide cylinder 42 provided on the guide base 41, and a guide member 43 provided at the output end of the guide cylinder 42 and corresponding to the guide port 2331.

[0023] In this embodiment, the caliber of the guide port is smaller than the diameter of the coil core and larger than the maximum diameter of the guide member, so as to achieve accurate guidance of the falling path of the coil core. The guide base 41 provides a stable installation foundation for the guide cylinder 42, ensuring the operational stability of the guide mechanism 4. The setting of the guide cylinder 42 enables the guide member 43 to perform telescopic movement as required, so that when the coil core reaches the limit baffle 233, the guide member 43 can quickly extend, pass through the guide port 2331 and abut against the top of the collection guide column 224, providing an accurate falling channel for the coil core. It effectively avoids the possible deviation or stagnation of the coil core during the falling process, ensures that it can be smoothly and accurately strung into the collection guide column 224, and improves the efficiency and quality of string collection. In addition, the guide mechanism 4 can also be designed in a variety of ways according to actual needs. For example, the guide member 43 can be made of flexible materials, such as silicone or rubber, to reduce the wear on its surface while guiding the coil core; the guide cylinder 42 can be replaced by an electric push rod or a hydraulic cylinder.

[0024] Furthermore, as a preferred embodiment of the present invention but not a limitation, the release assembly 23 also includes a first limiting mechanism 234 and a pulley assembly 235 disposed below the limiting baffle 233, and a second limiting mechanism 236 disposed on the pulley assembly 235, and the pulley assembly 235 drives the second limiting mechanism 236 to approach or move away from the first limiting mechanism 234 along the height direction of the guide rod assembly 22.

[0025] In this embodiment, by adding a first limiting mechanism 234, a pulley assembly 235 and a second limiting mechanism 236, the process of collecting the coil cores in a string is optimized. The first limiting mechanism 234 is located below the limiting baffle 233, and is used to initially block the coil cores that have just fallen, so as to prevent them from falling directly to the bottom of the collection guide column 224 and causing rupture. The pulley assembly 235 drives the second limiting mechanism 236 to gradually move downward along the height direction of the guide rod assembly 22 according to the number of coil cores that have fallen, so as to achieve the gradual stringing of the coil cores. When the coil core contacts the first limiting mechanism 234, the pulley assembly 235 drives the second limiting mechanism 236 to move downward, so that the second limiting mechanism 236 contacts the coil core and is stacked in sequence, and then the first limiting mechanism 234 is released, and the coil core continues to fall under the action of its own gravity, so that the distance that the coil core falls from the first limiting mechanism each time remains consistent. This process ensures that the coil core will not collide or be squeezed, deformed or damaged during the falling process due to excessive falling height. In addition, the first limiting mechanism 234 and the second limiting mechanism 236 can use pneumatic or electric actuators to achieve faster and more accurate limiting actions; the pulley assembly 235 can be replaced with a ball screw or a gear rack drive to provide higher motion accuracy and load capacity; the claw of the limiting mechanism can be designed to be adjustable to accommodate coil cores of different sizes. These improvements not only enhance the flexibility and adaptability of the release assembly 23, Furthermore, as a preferred embodiment of the present invention but not a limitation, the guide rod assembly 22 includes a turntable 221, a drive motor 222 for driving the turntable 221 to rotate, a plurality of positioning posts 223 arranged along the edge of the turntable 221, and a collecting guide post 224 detachably connected to each of the positioning posts 223 and for the coil core to be strung in.

[0026] In this embodiment, the setting of the turntable 221 allows multiple collection guides 224 to be installed on the positioning posts 223 on its edge, forming a rotatable workstation system. The drive motor 222 drives the turntable 221 to rotate, which can quickly and accurately move the completed collection guides 224 out of the working area, and move the empty collection guides 224 to the bottom of the release assembly 23 to prepare for receiving new coil cores. This design not only realizes continuous and efficient collection of coil cores in strings, but also reduces the equipment footprint and improves production efficiency.

[0027] Furthermore, as a preferred embodiment of the present invention but not a limitation, the first limiting mechanism 234 includes a guide rod 2341, a first mounting plate 2342 arranged on the top of the guide rod 2341, a top limiting cylinder 2343 arranged on the first mounting plate 2342, and a first limiting claw 2344 connected to the output end of the top limiting cylinder 2343 and used to be clamped into the outside of the collecting guide column 224 to limit the falling of the coil core; the second limiting mechanism 236 includes a second mounting plate 2361 connected to the pulley assembly 235 and slidably connected to the guide rod 2341, a bottom limiting cylinder 2362 arranged on the second mounting plate, and a second limiting claw 2363 connected to the output end of the bottom limiting cylinder 2362 and used to be clamped into the outside of the collecting guide column 224 to limit the falling of the coil core.

[0028] In this embodiment, the first limiting mechanism 234 provides support and installation foundation through the guide rod 2341 and the first mounting plate 2342, and the top limiting cylinder 2343 drives the first limiting claw 2344 to clamp into the outside of the collection guide column 224, and performs preliminary limiting on the falling coil core to prevent it from falling directly to the bottom. The second limiting mechanism 236 realizes sliding along the guide rod 2341 through the second mounting plate 2361 connected to the pulley assembly 235, and the bottom limiting cylinder 2362 drives the second limiting claw 2363 to gradually move downward and receive the coil core when it falls, ensuring that the height of each coil core entering the collection guide column from the first limiting claw remains consistent.

[0029] Furthermore, as a preferred embodiment of the present scheme but not a limitation, the winding device 1 includes a frame body 11, a discharging channel 12 arranged on the frame body 11, a weighing sensor 13 located at the end of the discharging channel 12, a first blanking cylinder 14 arranged on the frame body 11, a second blanking cylinder 15 connected to the output end of the first blanking cylinder 14 and arranged perpendicular to the first blanking cylinder 14, and a blanking enclosure 16 connected to the output end of the second blanking cylinder 15 and arranged above the weighing sensor 13, a defective material tray 17 is provided on the frame body 11 on the side corresponding to the extension and retraction direction of the first blanking cylinder 14, and a good product slide 18 connected to the material guide conveyor belt 3 is provided on the frame body 11 on the side corresponding to the extension and retraction direction of the second blanking cylinder 15.

[0030] In this embodiment, the discharge channel 12 guides the coil cores to slide orderly to the weighing sensor 13 for accurate weight detection to ensure that each core meets the quality standards. The vertical layout of the first drop cylinder 14 and the second drop cylinder 15, through the cooperation of the drop enclosure 16, realizes the automatic sorting of the tested cores: the qualified cores are pushed by the second drop cylinder 15 to the good slide 18, and slide into the guide conveyor belt 3 for subsequent collection in strings; the unqualified cores are pushed by the first drop cylinder 14 to the bad material tray 17 for centralized collection and processing.

[0031] Furthermore, as a preferred implementation mode of the present invention but not limiting, it includes a plurality of winding devices 1 arranged along the length direction of the material guide conveyor belt 3 .

[0032] In this embodiment, multiple winding devices 1 work in parallel and can produce multiple groups of coil cores at the same time. These cores are continuously and efficiently transported to the string rod device 2 through the material conveyor belt 3 for collection in strings. The transportation capacity of the material conveyor belt 3 is fully utilized, and the production cycle is greatly shortened through parallel processing, meeting the production needs of high output and high efficiency. In addition, when one of the winding devices 1 needs maintenance or replacement, the other winding devices 1 can continue to work, ensuring the continuity of production and reducing downtime and production losses. At the same time, this modular design is also convenient for increasing or decreasing the number of winding devices 1 according to actual production needs, flexibly adjusting production capacity, and adapting to production tasks of different scales. The layout and control method of multiple winding devices 1 can be further optimized. For example, the winding device 1 can be arranged in a staggered manner to maximize the use of the width of the material conveyor belt 3.

[0033] Furthermore, as a preferred implementation of the present solution but not a limitation, a supporting platform 2241 for supporting the coil core is provided at the bottom of the collecting guide column 224 .

[0034] In this embodiment, the setting of the supporting platform can keep the strings of coil cores on the collecting guide pins. When the operator removes the strings of cores from the positioning pins together with the collecting guide pins, it is easier to transfer them to the next step of heat processing, reducing the extra workload and potential safety risks caused by the loosening or falling of the cores.

[0035] Furthermore, as a preferred implementation of the present solution but not a limitation, the top of the collecting guide column 224 is in a conical shape.

[0036] In this embodiment, the conical design helps guide the coil core to enter the collection guide more smoothly, reducing the friction and resistance of the coil core during the entry process, thereby reducing the risk of wear and scratches on the surface of the coil core and improving product quality. Secondly, the conical top can more effectively center the coil core, ensuring that the coil core is accurately and centrally strung into the collection guide.

[0037] An automatic stringing process comprises the following steps: The winding device 1 transfers the coil core to the material conveying belt 3; The material guide conveyor belt 3 conveys the coil core to the climbing conveyor belt 231 to transfer the coil core to the limiting baffle 233 located above the collecting guide column 224; The guide cylinder 42 extends to drive the guide member 43 to pass through the guide opening 2331 and abut against the top of the collecting guide column 224; The telescopic cylinder 232 extends to drive the limit baffle 233 to withdraw from the collecting guide column 224, and the coil core passes through the guide opening 2331 along the guide member 43 and then enters the collecting guide column 224 and abuts against the first limit claw 2344; The top limiting cylinder 2343 extends to drive the first limiting claw 2344 to withdraw from the outside of the collecting guide column 224, and the coil core falls down and abuts against the second limiting claw 2363; The pulley assembly 235 drives the second limiting claw 2363 to move downward relative to the first limiting claw 2344 by the thickness of a single coil core; The guide cylinder 42 and the telescopic cylinder 232 are reset, and the above steps are repeated.

[0038] In this embodiment, production efficiency and product quality are significantly improved, and the error and damage risk of manual operation are reduced through automated control. At the same time, close coordination between the steps ensures the consistency and reliability of the magnetic core stringing.

[0039] Further, as a preferred embodiment of the present invention but not limiting, the step of transferring the coil core to the material-conducting conveyor belt 3 by the winding device 1 further includes: The coil core flows through the discharge channel 12 and then slides down to the weighing sensor 13 for weighing; If the current coil core meets the weight standard, the second blanking cylinder 15 extends, and the blanking enclosure 16 pushes the coil core to the good slide 18 and then slides into the material guide conveyor belt 3; if the current coil core does not meet the weight standard, the first blanking cylinder 14 extends, and the blanking enclosure 16 pushes the coil core to the defective material tray 17 for collection.

[0040] In this embodiment, product quality is improved, and magnetic cores that do not meet the requirements are effectively eliminated through automated weight detection and sorting, which also improves production efficiency and reduces manual intervention and potential quality problems. At the same time, this automated detection and sorting method can operate continuously and stably, ensuring the consistency and reliability of the production process.

[0041] Furthermore, as a preferred implementation mode of this solution but not limiting, the following steps are also included: The bottom limiting cylinder 2362 extends to drive the second limiting claw 2363 to withdraw from the outside of the collecting guide column 224; The driving motor 222 drives the rotating disk 221 to rotate, driving another adjacent collecting guide column 224 to move below the limiting baffle 233; The pulley assembly 235 drives the second limiting claw 2363 to move upward relative to the first limiting claw 2344 to reset; The bottom limiting cylinder 2362 retracts and drives the second limiting claw 2363 to clamp into the outer side of the collecting guide column 224 .

[0042] In this embodiment, the function of the automatic rod stringing device is further improved, and its ability to work continuously is enhanced. Specifically, the bottom limit cylinder 2362 extends, drives the second limit claw 2363 to withdraw from the outside of the collection guide column 224, releases the limit on the inserted magnetic core, and prepares for subsequent operations. Then, the drive motor 222 is started, drives the turntable 221 to rotate, moves the collection guide column 224 that has been inserted out of the working area, and rotates another empty collection guide column 224 to the bottom of the limit baffle 233, ready to receive a new coil magnetic core. After the turntable 221 rotates to the right position, the pulley assembly 235 drives the second limit claw 2363 to move upward, so that it is reset relative to the first limit claw 2344, and prepares for the next magnetic core stringing. Finally, the bottom limit cylinder 2362 retracts, drives the second limit claw 2363 to re-engage the outside of the collection guide column 224, restores to the initial state, and prepares for the next coil magnetic core stringing operation.

[0043] The working principle of this embodiment is as follows: The present application discloses an automatic stringing device and process thereof, which realizes the continuous automated operation of coil cores from output to collection in strings through an automated winding device, a stringing device and a material guide conveyor belt, which not only improves production efficiency, but also significantly improves the consistency of product quality.
