[0034] The present application will be further described in detail below with reference to the accompanying drawings

[0035] See Figures 1-4 As shown, a coil blanking mechanism is shown, including a frame 3, a sliding seat 4 that can be translated and lifted and is arranged on the frame 3, a fourth driving module 5 for driving the sliding seat 4 to move, and a material-pressing component 2 and a material-carrying component 1 arranged vertically on the sliding seat 4. Among them, the fourth driving module 5 includes two groups of motor screw structures arranged on the frame 3, and these two groups of motor screw structures can respectively drive the sliding seat 4 to move along the horizontal direction and the vertical direction to sequentially place the coils into several magnetic cores on the tray

[0036] In this embodiment, as shown in Figures 2-3 the material-carrying component 1 includes a material-carrying seat 1a rotatably arranged around the horizontal direction, a first driving module 1b for driving the material-carrying seat 1a to rotate, a material-carrying groove 1c opened in the material-carrying seat 1a, a material-supporting column 1d slidably arranged vertically through the material-carrying groove 1c, a second driving module 1e for driving the material-supporting column 1d to lift and lower, a first material groove 1f opened in the material-supporting column 1d, and a material-carrying rod 1g slidably arranged vertically through the first material groove 1f; among them, the first driving module 1b is a motor, the motor is arranged on the sliding seat 4, the extending direction of the output shaft of the motor is perpendicular to the translation direction of the sliding seat 4, and a turntable 1m is coaxially connected thereto, and the material-carrying seat 1a is arranged on the turntable 1m

[0037] Combined with Figure 2 and Figure 4As shown in the figure, the blanking component 2 is located above the material supporting component 1. It includes a blanking seat 2a which is arranged to be translatable and liftable, a third driving module 2b for driving the movement of the blanking seat 2a, and a blanking column 2c arranged at the bottom of the blanking seat 2a and extending along the vertical direction. A second material groove 2d is axially formed in the blanking column 2c. Among them, the third driving module 2b includes a second air cylinder 2b1 and a third air cylinder 2b2. The second air cylinder 2b1 is arranged on the sliding seat 4. The piston rod of the second air cylinder 2b1 extends and retracts along the horizontal direction and is connected with a second slider 2g. The moving direction of the second slider 2g is the same as the translation direction of the sliding seat 4. The third air cylinder 2b2 is arranged on the second slider 2g. The piston rod of the third air cylinder 2b2 extends and retracts along the vertical direction and is connected with a third slider 2h. The blanking seat 2a is arranged on the third slider 2h.

[0038] The blanking seat 2a has a first position and a second position. When the blanking seat 2a is in the first position, the blanking column 2c is buckled on the material supporting groove 1c, and the first material groove 1f is in positive alignment and butt joint with the second material groove 2d. When the blanking seat 2a is in the second position, the blanking column 2c is located at the side of the material supporting groove 1c.

[0039] During blanking, the winding mechanism feeds the coil into the material supporting groove 1c. Subsequently, the blanking seat 2a reaches the first position, and the blanking column 2c is buckled on the material supporting groove 1c. Then, the material supporting column 1d rises and presses the coil in the material supporting groove 1c upward against the bottom of the blanking column 2c. Subsequently, the material supporting rod 1g rises and penetrates into the coil. Then, the blanking seat 2a moves to the second position, the material supporting seat 1a rotates 180°, the sliding seat 4 drives the material supporting seat 1a to translate and lift and makes the material supporting rod 1g contact the magnetic core. Then, the material supporting column 1d descends and accurately places the coil on the material supporting rod 1g into the magnetic core. The coil can be accurately placed into the magnetic core under the cooperation of the material supporting column 1d, the blanking column 2c and the material supporting rod 1g, which not only improves the processing quality of the inductor, but also does not damage the coil.

[0040] In this embodiment, as shown in combination with Figure 3 the figure, a first sliding groove 1h with an open lower end is formed in the material supporting seat 1a. The material supporting groove 1c is formed at the top of the material supporting seat 1a and is communicated with the first sliding groove 1h. The material supporting column 1d includes a first sliding part 1d1 slidably arranged in the first sliding groove 1h and a material supporting part 1d2 arranged at the upper end of the first sliding part 1d1. The diameter of the first sliding part 1d1 is larger than that of the material supporting part 1d2. The material supporting part 1d2 penetrates through the material supporting groove 1c.

[0041] A second chute 1i is formed in the first sliding part 1d1, and a first material chute 1f is formed in the material supporting part 1d2 and communicated with the second chute 1i. The material supporting rod 1g includes a second sliding part 1g1 slidably arranged in the second chute 1i and a material supporting part 1g2 arranged at the upper end of the second sliding part 1g1. The diameter of the second sliding part 1g1 is larger than that of the material supporting part 1g2, and the material supporting part 1g2 penetrates through the first material chute 1f.

[0042] In this embodiment, the lower end of the first sliding part 1d1 penetrates out of the first chute 1h and is connected with a first driving part 1d3. The second driving module 1e includes a first air cylinder 1e1. The piston rod of the first air cylinder 1e1 extends along the vertical direction and is connected with a first slider 1e2. The first slider 1e2 is connected with the first driving part 1d3.

[0043] A third chute 1j with an open lower end is formed in the first driving part 1d3. The third chute 1j is communicated with the second chute 1i. The lower end of the second sliding part 1g1 penetrates through the third chute 1j and is sleeved with a second driving part 1g3. The second driving part 1g3 is in clearance fit with the third chute 1j. An air extraction hole 1k communicated with the third chute 1j is formed in the first driving part 1d3.

[0044] The air extraction hole 1k is communicated with an external air extraction mechanism. Under the air extraction action of the air extraction mechanism, a negative pressure state is maintained in the third chute 1j and the second chute 1i, and the second driving part 1g3 can drive the material supporting rod 1g to rise under the action of the negative pressure; after the air extraction mechanism is closed, due to the open lower end of the third chute 1j, the negative pressure in the third chute 1j and the second chute 1i gradually disappears, and the second driving part 1g3 can drive the material supporting rod 1g to descend under the action of gravity.

[0045] In this embodiment, the material supporting assembly 1 further includes a limiting module 1l located below the material supporting seat 1a. The limiting module 1l includes a first limiting plate 1l1 and a second limiting plate 1l2 arranged vertically. A through hole 1l4 is formed in the first limiting plate 1l1. The second sliding part 1g1 penetrates through the through hole 1l4 and its lower end is connected with a limiting block 1g4. The length of the limiting block 1g4 is greater than the aperture of the through hole 1l4. A limiting groove 1l3 for accommodating the limiting block 1g4 is formed in the second limiting plate 1l2. The limiting module 1l can limit the limiting block 1g4 and prevent the material supporting rod 1g from moving excessively and damaging the coil.

[0046] In this embodiment, as shown in combination Figure 4 An installation groove 2e is formed at the bottom of the pressing seat 2a. A spring 2f is accommodated in the installation groove 2e. The pressing column 2c is inserted into the installation groove 2e and connected with the spring 2f. The spring 2f can buffer the pressing column 2c and prevent the material supporting column 1d from directly colliding with the pressing column 2c rigidly during the rising process and damaging the coil.

[0047] A cutter (not shown in the figure) is further provided on the circumferential side of the lower end of the pressure column 2c for cutting the end of the coil when the pressure column 2c contacts the material supporting column 1d.

[0048] The implementation principle of an inductor blanking mechanism according to an embodiment of the present application is as follows:

[0049] When the pressure seat 2a is in the second position, the pressure column 2c is located on the side of the material receiving groove 1c. The sliding seat 4 drives the pressure seat 2a to move and approach the winding mechanism, and the winding mechanism feeds the coil into the material receiving groove 1c.

[0050] Subsequently, the pressure seat 2a moves to the first position, the pressure column 2c is buckled on the material receiving groove 1c, the material supporting column 1d rises and presses the coil in the material receiving groove 1c upward against the bottom of the pressure column 2c. The cutter on the circumferential side of the bottom of the pressure column 2c cuts off the end of the coil under the impact of the material supporting column 1d and the pressure column 2c.

[0051] Subsequently, the material receiving rod 1g rises and penetrates into the coil. The material receiving seat 1a rotates 180°, making the material receiving rod 1g face downward. The sliding seat 4 drives the material receiving seat 1a to translate and lift, and makes the material receiving rod 1g contact the magnetic core. The material supporting column 1d descends and places the coil on the material receiving rod 1g into the magnetic core.

[0052] Subsequently, the material receiving seat 1a rotates 180° again to make the material receiving rod 1g face upward. The material supporting column 1d and the material receiving rod 1g descend, and the material receiving groove 1c continues to receive the coil output by the winding mechanism. Subsequently, the above blanking steps are repeated.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
