Obviously, the drawings in the following description are only some embodiments of the present application, and other drawings can be obtained by those skilled in the art without creative labor.

[0024] Figure 3 is Figure 1 an enlarged view of B in FIG. 1. DETAILED DESCRIPTION

[0026] In order to make the technical problems, technical solutions and beneficial effects of the present application clearer, the present application will be further described in detail below in conjunction with the drawings and examples. It should be understood that the specific examples described herein are only intended to explain the present application and not to limit the present application.

[0027] Referring to Figures 1 to 3 A string rod machine, comprising a string rod device 1 for collecting the coil magnetic cores in a string, a release assembly 2 for delivering the coil magnetic cores above the string rod device 1 and releasing, and a guide mechanism 3 for preventing the coil magnetic cores from deviating from the string rod device 1 during the releasing, the string rod device 1 comprising a string rod frame 11, a guide rod assembly 12 arranged on the string rod frame 11, the release assembly 2 comprising a climbing conveyor belt 21, a telescopic air cylinder 22 arranged at the end of the climbing conveyor belt 21 and parallel to the climbing conveyor belt 21, and a limiting baffle 23 connected with the output end of the telescopic air cylinder 22.

[0028] The string rod machine of the present application realizes the collection of the coil magnetic cores in a string through the guide rod assembly, the release assembly delivers the coil magnetic cores accurately to above the string rod device and releases by using the climbing conveyor belt and the telescopic air cylinder, and the guide mechanism ensures that the coil magnetic cores do not deviate from the predetermined position during the releasing process. Compared with the traditional manual operation mode, the device significantly reduces the problem of inconsistent quality caused by individual skill differences and work state fluctuations, avoids the risk of crushing or scratching of the coil magnetic cores during the taking, and thus improves the production efficiency and operation safety while ensuring the product quality.

[0029] Further, as a preferred embodiment of the present application but not as a limitation, the limiting baffle 23 is provided with a guide opening 231, the guide mechanism 3 comprises a guide base 31 arranged at the end of the climbing conveyor belt 21, a guide air cylinder 32 arranged on the guide base 31, and a guide piece 33 arranged at the output end of the guide air cylinder 32 and corresponding to the guide opening 231.

[0030] In this embodiment, the caliber of the guide port is smaller than the diameter of the coil magnetic core and larger than the maximum diameter of the guide piece, achieving precise guidance of the coil magnetic core's falling path. The guide base provides a stable mounting foundation for the guide cylinder, ensuring the stability of the guide mechanism's operation. The guide cylinder allows the guide piece to extend or retract as needed, so that when the coil magnetic core reaches the limit stop, the guide piece can quickly extend, pass through the guide port and abut the top of the collection guide column, providing an accurate falling channel for the coil magnetic core. This effectively avoids the coil magnetic core from deviating or jamming during the falling process, ensuring that it can smoothly and accurately string into the collection guide column, improving the efficiency and quality of the string collection. In addition, the guide mechanism can also be diversified according to actual needs. For example, the guide piece can be made of flexible materials such as silicone or rubber to reduce wear on the surface of the coil magnetic core while guiding it; the guide cylinder can be replaced by an electric push rod or a hydraulic cylinder.

[0031] Further, as a preferred embodiment of the present scheme but not limited, the release assembly 2 further comprises a first limiting mechanism 24 and a pulley assembly 25 arranged below the limit stop 23, and a second limiting mechanism 26 arranged on the pulley assembly 25, the pulley assembly 25 drives the second limiting mechanism 26 to move towards or away from the first limiting mechanism 24 along the height direction of the guide rod assembly 12.

[0032] In this embodiment, by adding a first limiting mechanism, a pulley assembly and a second limiting mechanism, the string collection process of the coil magnetic core is optimized. The first limiting mechanism is located below the limit stop and is used to preliminarily block the coil magnetic core just after falling, preventing it from falling directly to the bottom of the collection guide column and causing breakage. The pulley assembly drives the second limiting mechanism to gradually move downward along the height direction of the guide rod assembly according to the number of falling coil magnetic cores, achieving the gradual stringing of the coil magnetic cores. When the coil magnetic core contacts the first limiting mechanism, the pulley assembly drives the second limiting mechanism to move downward, so that the second limiting mechanism contacts and stacks the coil magnetic cores in turn, and then the first limiting mechanism is released. The coil magnetic core continues to fall under the action of its own gravity, so that the distance of the coil magnetic core falling from the first limiting mechanism each time remains consistent. This process ensures that the coil magnetic core will not collide or be squeezed and deformed or damaged due to excessive falling height during the falling process. In addition, the first limiting mechanism and the second limiting mechanism can be equipped with pneumatic or electric actuators to achieve faster and more accurate limiting actions; the pulley assembly can be replaced by a ball screw or a gear and rack transmission to provide higher motion accuracy and load capacity; the claw part of the limiting mechanism can be designed to be adjustable to adapt to coil magnetic cores of different sizes. These improvements not only enhance the flexibility and adaptability of the release assembly.

[0033] Further, as a preferred embodiment of the present scheme but not as a limitation, the guide rod assembly 12 comprises a rotating disc 121, a driving motor 122 for driving the rotating disc 121 to rotate, a plurality of positioning columns 123 arranged along the edge of the rotating disc 121, and a collection guide column 124 which is detachably connected with each of the positioning columns 123 and into which the coil magnetic core string is inserted.

[0034] In the present embodiment, the rotating disc is arranged to allow the plurality of collection guide columns to be mounted on the positioning columns at the edge thereof, forming a rotatable work station system. The driving motor drives the rotating disc to rotate, which can quickly and accurately move the collection guide column with the completed string insertion out of the working area, and rotate the empty collection guide column to below the release assembly, ready to receive the new coil magnetic core. This design not only realizes continuous and efficient string collection of coil magnetic cores, but also reduces the equipment footprint and improves production efficiency.

[0035] Further, as a preferred embodiment of the present scheme but not as a limitation, the first limiting mechanism 24 comprises a guide rod 241, a first mounting plate 242 arranged at the top of the guide rod 241, a top limiting pneumatic cylinder 243 arranged on the first mounting plate 242, and a first limiting claw 244 connected with the output end of the top limiting pneumatic cylinder 243 and used for clamping into the outside of the collection guide column 124 to limit the falling of the coil magnetic core; the second limiting mechanism 26 comprises a second mounting plate 261 connected with the belt pulley assembly 25 and slidingly connected on the guide rod 241, a bottom limiting pneumatic cylinder 262 arranged on the second mounting plate, and a second limiting claw 263 connected with the output end of the bottom limiting pneumatic cylinder 262 and used for clamping into the outside of the collection guide column 124 to limit the falling of the coil magnetic core.

[0036] In the present embodiment, the first limiting mechanism provides support and installation basis through the guide rod and the first mounting plate, the top limiting pneumatic cylinder drives the first limiting claw to clamp into the outside of the collection guide column to preliminarily limit the falling of the coil magnetic core, preventing it from falling directly to the bottom. The second limiting mechanism realizes sliding along the guide rod through the second mounting plate connected with the belt pulley assembly, and the bottom limiting pneumatic cylinder drives the second limiting claw to gradually move downward and receive the coil magnetic core when it falls, ensuring that the height of each coil magnetic core falling from the first limiting claw into the collection guide column remains consistent.

[0037] Further, as a preferred embodiment of the present scheme but not as a limitation, the guide opening 231 is in a U shape and the opening faces the climbing conveyor belt 21, and the diameter of the guide opening 231 is smaller than the diameter of the coil magnetic core and larger than the diameter of the guide piece 33.

[0038] Further, as a preferred embodiment of the present scheme but not as a limitation, the bottom of the collection guide column 124 is provided with a supporting platform 1241 for supporting the coil magnetic core.

[0039] In this embodiment, the support platform can keep the stringed coil magnetic cores on the collection guide column. When the operator takes the stringed magnetic cores off the positioning column together with the collection guide column, the next step of transferring for heat processing can be performed more easily, and the additional workload and potential safety risks caused by the loosening or falling of the magnetic cores are reduced.

[0040] Further, as a preferred embodiment of the present scheme but not limited, the top of the collection guide column 124 is conical in shape.

[0041] In this embodiment, the conical design helps guide the coil magnetic cores to enter the collection guide column more smoothly, reducing friction and resistance during the entry process, thereby reducing the risk of wear and tear on the surface of the coil magnetic cores and improving product quality. Secondly, the conical top can more effectively center the coil magnetic cores, ensuring that the coil magnetic cores are accurately and centrally strung into the collection guide column.

[0042] Further, as a preferred embodiment of the present scheme but not limited, the stringing rod rack 11 is provided with a pulley assembly 111 at the bottom.

[0043] In this embodiment, the flexibility and mobility of the device are enhanced, allowing the automatic stringing rod device to quickly and easily adjust its position according to production needs, optimizing production layout and improving work efficiency. In addition, the pulley assembly also facilitates regular maintenance and repair of the device, reducing the labor and time costs required for device position adjustment.

[0044] Further, as a preferred embodiment of the present scheme but not limited, it also includes a control panel 4 on the stringing rod rack 11.

[0045] In this embodiment, an interface for centralized control and management of the automatic stringing rod device is provided for the operator, simplifying the operation process of the device and improving user experience. Through the control panel, the operator can conveniently set and adjust the working parameters of the device, monitor the running state of the device, respond to abnormal situations in a timely manner, and ensure the smooth progress of the production process.

[0046] The working principle of the present embodiment is as follows:

[0047] The stringing rod machine of the present application realizes the stringing collection of coil magnetic cores through the guide rod assembly, and the release assembly uses a climbing conveyor belt and a telescopic cylinder to accurately deliver the coil magnetic cores to the upper part of the stringing rod device and release them. The guide mechanism ensures that the coil magnetic cores do not deviate from the predetermined position during the release process. Compared with the traditional manual operation method, this device significantly reduces the inconsistency in quality caused by individual skill differences and work state fluctuations, avoids the risk of crushing or scratching of the coil magnetic cores during handling, and thus improves production efficiency and operation safety while ensuring product quality.
