[0002] Reactors, also known as inductors, are electrical devices widely used in circuits that rely on the inductive reactance of a coil to block current changes. Its working principle is based on the law of electromagnetic induction. When current passes through a coil, a magnetic field is generated in the reactor, which interacts with the external magnetic field to generate impedance and limit current changes. Reactors have many functions and uses, including preventing rapid changes in current, isolating circuits to avoid large amounts of electrons, balancing voltage differences, enhancing or limiting current to protect circuit components, storing electrical energy to ensure normal operation of circuits, and achieving reactive power compensation.

[0003] In the power system, reactors are widely used, especially in high-voltage transmission lines, reactive power compensation devices, motor drivers, power filters, etc. When selecting a reactor, it is necessary to consider factors such as the reactor's reactance K value, structure (air core, iron core), and installation location (power side, neutral point side), and comprehensively compare technical performance and price indicators to achieve the best results.

[0020] Refer to the attached Figure 1-6 , an automatic assembly line for a reactor, comprising a first conveyor 1 and a second conveyor 2, and a material taking and placing mechanism 3 arranged therebetween; The material taking and placing mechanism 3 comprises a connecting rod assembly 31, and a first mounting plate 32 driven by the connecting rod assembly 31 to swing back and forth 90 degrees, and the swinging track of the first mounting plate 32 is from the vertical direction to the horizontal direction; A fourth bracket 4 is provided between the material taking and placing mechanism 3 and the second conveyor 2, a rotating roller 5 is rotatably mounted on the fourth bracket 4, a second mounting plate 6 is mounted on the side wall of the rotating roller 5, four second mounting plates 6 are arranged along the circumference of the axis of the rotating roller 5, and a clamping mechanism 7 is provided on both the first mounting plate 32 and the second mounting plate 6; A support platform 8 is provided below the rotating roller 5 , and a second cylinder 9 extending and retracting in the vertical direction is mounted on the top of the support platform 8 . A lifting plate 10 is fixedly mounted on the retractable end of the second cylinder 9 , and a mounting mold 11 is provided on the top of the lifting plate 10 .

[0021] In this embodiment, the first conveyor 1 repeatedly transports the lower iron core, coil and upper iron core of the reactor in sequence, and the connecting rod assembly 31 can drive the first mounting plate 32 to swing back and forth between the top of the first conveyor 1 and the left side of the rotating roller 5, and then the lower iron core can be clamped by the clamping mechanism 7 of the first mounting plate 32, and placed on the clamping mechanism 7 on the second mounting plate 6 on the left for clamping, then the rotating roller 5 rotates until the iron core is directly above the lifting plate 10, and the second cylinder 9 pushes the lifting plate 10 to rise, so that the clamping mechanism 7 can release the lower iron core and then it can fall stably into the installation mold 11, and similarly, the coil and the upper iron core are also placed in the installation mold 11 in sequence, and finally the installed reactor is clamped by the clamping mechanism 7 on the second mounting plate 6 located below, and as the rotating roller 5 rotates, the reactor is placed on the second conveyor 2 for transportation, and the assembly of the reactor can be completed automatically. Compared with manual assembly, its work efficiency is greatly improved.

[0022] The connecting rod assembly 31 includes a first bracket 311, and driving rods 312 are arranged on both sides of the first bracket 311. The ends of the driving rods 312 are fixedly connected to the first mounting plate 32 and are provided with a slide groove 3121. A slider 313 is slidably installed in the slide groove 3121, and the slider 313 is rotatably installed with the first bracket 311.

[0023] In this embodiment, when the slider 313 rotates on the first bracket 311 and slides in the slide groove 3121, the driving rod 312 can perform a reciprocating swing motion from vertical to horizontal, and the first mounting plate 32 is fixedly connected thereto to maintain synchronous movement.

[0024] The connecting rod assembly 31 includes a second bracket 317, on which a first connecting rod 316 is rotatably mounted, on which a first connecting rod 314 is fixedly mounted, there are two first connecting rods 314, and the other ends of the first connecting rods 314 are respectively hingedly connected to the two driving rods 312, and a second connecting rod 315 is also fixedly mounted on the first connecting rod 316, the other end of the second connecting rod 315 is hingedly connected to a third connecting rod 318, the other end of the third connecting rod 318 is hingedly connected to a fourth connecting rod 319, the other end of the fourth connecting rod 319 is fixedly mounted on the second connecting rod 320, the second connecting rod 320 is rotatably mounted on the third bracket 321, and a servo motor 322 is assembled at the end.

[0025] In this embodiment, after the servo motor 322 is started, the fourth connecting rod 319 rotates synchronously, which can pull the third connecting rod 318 to swing back and forth, and the third connecting rod 318 then pulls the first connecting rod 314 and the second connecting rod 315 to swing back and forth, and finally pulls the driving rod 312, and cooperates with the rotation connection between the slider 313 and the first bracket 311, and the inner sliding connection between the slider 313 and the slide groove 3121, so that the driving rod 312 can perform a reciprocating swinging motion from vertical to horizontal.

[0026] The third bracket 321 is provided with an internal gear 12, and the internal gear 12 is meshedly connected with an external gear 13. The external gear 13 is rotatably mounted on a transmission rod 14, and the transmission rod 14 is fixedly connected to the second connecting rod 320. A fifth connecting rod 15 is provided on the rotating shaft of the external gear 13, and a shifting rod 16 is fixedly connected to the fifth connecting rod 15. The shifting rod 16 matches with a shifting member 18. There are four shifting members 18, which are arranged in a circle on a transmission plate 17 fixedly mounted on the rotating shaft of the rotating roller 5.

[0027] In this embodiment, when the second connecting rod 320 rotates, the transmission rod 14 rotates synchronously, and the outer gear 13 rotates by itself while following the rotation of the transmission rod 14 through the engagement with the inner gear 12. The fifth connecting rod 15 rotates together and drives the lever 16 to shift the shifting member 18, so that the rotating roller 5 rotates, thereby realizing the linkage between the two.

[0028] It should be noted that the number of teeth of the outer gear 13 is one quarter of that of the inner gear 12 , so the inner gear 12 rotates one circle along the outer gear 13 and rotates a quarter of a circle by itself, that is, the lever 16 will move the shifting member 18 each time to rotate the rotating roller 5 90 degrees.

[0029] An arc plate 19 is also fixedly mounted on the second connecting rod 320 . The arc plate 19 matches with an arc groove 171 formed on the side of the transmission plate 17 . There are four arc grooves 171 , which are located between two adjacent shifting members 18 .

[0030] In this embodiment, after the lever 16 leaves the shifting member 18 , the arc plate 19 will be placed in the arc groove 171 , thereby limiting the position of the arc plate 19 and preventing the rotating roller 5 from rotating.

[0031] The clamping mechanism 7 includes two first cylinders 71, the telescopic ends of the two first cylinders 71 are relatively distributed and are fixedly connected with a clamping plate 72, and a plurality of evenly distributed movable grooves 721 are opened on the clamping plate 72. A limiting column 73 is slidably installed in the movable groove 721, and the end of the limiting column 73 is connected to the inner wall of the movable groove 721 by a spring 74.

[0032] In this embodiment, after the two first cylinders 71 are started, the two clamps 72 can be driven closer to each other. When the limit column 73 abuts against the reactor accessory, it will cooperate with the spring 74 and slide in the movable groove 721 to different degrees according to its convex and concave conditions, so that different reactor accessories can be clamped.

It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
