DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention. Example

[0025] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , which is the first embodiment of the present utility model, which provides an automatic voice coil wire winding machine, including a chassis 1, a coil 4 is provided on the outer surface of the chassis 1, a clamping assembly 2 is provided on the outer surface of the chassis 1, and a wire management assembly 3 is provided inside the chassis 1, the clamping assembly 2 includes a rotating disk 205 movably connected to the outer surface of the chassis 1, the outer surface of the rotating disk 205 is fixedly connected to a linear limit disk 206, the outer surface of the linear limit disk 206 is slidably connected to a plurality of rotating blocks 209, the end of the rotating block 209 away from the linear limit disk 206 is fixedly connected to an L-shaped connecting rod 208, the outer surface of the L-shaped connecting rod 208 is slidably connected to an arc-shaped limit disk 202, the top of the L-shaped connecting rod 208 is fixedly connected to an inner support block 204, the side surface of the arc-shaped limit disk 202 is movably connected to the outer surface of the rotating disk 205, and the side of the arc-shaped limit disk 202 away from the rotating disk 205 is fixedly connected to the limit shaft 203.

[0026] Specifically, the inner wall of the chassis 1 is fixedly connected to the reduction motor 201, and the output end of the reduction motor 201 is fixedly connected to the side of the rotating disk 205 away from the arc-shaped limit disk 202. The arc-shaped limit disk 202 is provided with an arc-shaped limit groove 207 on the side away from the rotating disk 205. One end of the L-shaped connecting rod 208 slides in the arc-shaped limit groove 207. The outer surface of the rotating disk 205 is provided with a plurality of blocks, and the outer surface of the fixed limit disk is provided with a plurality of buckles that cooperate with the blocks. The linear limit disk 206 is provided with a plurality of straight grooves that cooperate with the rotating block 209 on the side close to the L-shaped connecting rod 208, and the rotating block 209 slides in the straight groove.

[0027] Furthermore, by rotating the arc limit disk 202, the L-shaped connecting rod 208 is driven to slide in the arc limit groove 207. At the same time, the rotating block 209 slides in the straight groove opened on the outer surface of the linear limit disk 206, and finally the inner support block 204 moves outward as the L-shaped connecting rod 208 moves in the arc limit groove 207, thereby achieving internal support for the winding reel. After the rotation is completed, the buckle on the outer surface of the arc limit disk 202 is matched with the block on the outer surface of the rotating disk 205, so that the rotating disk 205 is fixed to the arc limit disk 202, and then the rotating disk 205 is driven to rotate by the reduction motor 201, thereby driving the winding reel fixed by the internal support block 204 to rotate. Example

[0028] Reference Figure 1 and Figure 5 , which is the second embodiment of the present utility model, and is based on the previous embodiment. The cable management component 3 includes a first threaded rod 303 movably connected to the inside of the chassis 1 through a bearing seat, the outer surface of the first threaded rod 303 is threadedly connected to a moving block 304, and the side of the moving block 304 close to the clamping component 2 is fixedly connected to a cable management ring 305, the inner wall of the chassis 1 is movably connected to a second threaded rod 311 through a bearing seat, the outer surface of the second threaded rod 311 is threadedly connected to a blocking block 310, and the side of the blocking block 310 close to the moving block 304 is fixedly connected to a second sensor 309, the side of the blocking block 310 close to the clamping component 2 is fixedly connected to a connecting plate 307, and the side of the connecting plate 307 close to the clamping component 2 is fixedly connected to the first sensor 306.

[0029] Specifically, the inner wall of the chassis 1 is fixedly connected to a first servo motor 301, the output end of the first servo motor 301 is fixedly connected to one end of the second threaded rod 311, the inner wall of the chassis 1 is fixedly connected to a second servo motor 302, the output end of the second servo motor 302 is fixedly connected to one end of the first threaded rod 303, and a limiting rod 308 is inserted inside the moving block 304 and the blocking block 310.

[0030] Furthermore, the first servo motor 301 drives the second threaded rod 311 to rotate, thereby driving the blocking block 310 to move. During the movement of the blocking block 310, the connecting plate 307 and the first sensor 306 are driven to move until the first sensor 306 senses the position of the winding drum, and then controls the first servo motor 301 to stop, thereby determining the distance that the moving block 304 drives the wire management ring 305 to move according to the length of the winding drum, and then the second servo motor 302 drives the first threaded rod 303 to rotate, so that the moving block 304 drives The wire management ring 305 moves to manage the wires. When it moves to a position close to the blocking block 310, the moving block 304 does not contact the second sensor 309. When the second sensor 309 senses the approach of the moving block 304, it controls the second servo motor 302 to reverse, thereby driving the first threaded rod 303 to reverse. When the moving block 304 moves to the end of the first threaded rod 303 away from the blocking block 310, the servo motor reverses again, driving the moving block 304 to move in the opposite direction, and repeats this process, ultimately achieving wire management according to the different lengths of the cable reels.

[0031] Working principle: When winding the voice coil wire, the winding reel is inserted into the limiting shaft 203, and then the arc-shaped limiting disk 202 is rotated to drive the L-shaped connecting rod 208 to slide in the arc-shaped limiting groove 207. At the same time, the rotating block 209 slides in the straight groove provided on the outer surface of the linear limiting disk 206, and finally the inner support block 204 moves outward with the movement of the L-shaped connecting rod 208 in the arc-shaped limiting groove 207, thereby achieving internal support of the winding reel. After the rotation is completed, the buckle on the outer surface of the arc-shaped limiting disk 202 cooperates with the block on the outer surface of the rotating disk 205, so that the rotating disk 205 and the arc-shaped limiting disk 202 are fixed. Then the first servo motor 301 is started to drive the second threaded rod 311 to rotate, thereby driving the blocking block 310 to move. During the movement of the blocking block 310, the connecting plate 307 and the first sensor 306 are driven to move until the first sensor 306 senses the position of the winding reel. The first servo motor 301 is controlled to stop, and then the reduction motor 201 is started, thereby driving the rotating disk 205 to rotate, and the arc limit disk 202 is driven to rotate through the buckle on the outer surface of the arc limit disk 202 and the block on the outer surface of the rotating disk 205, and finally the inner support winding shaft is driven to rotate. When the reduction motor 201 is started, the second servo motor 302 is started at the same time, so that when the winding shaft is winding, the wire passing through the coil 4 passes through the wire management ring 305 to achieve wire management. When the moving block 304 moves to a position close to the blocking block 310, the second sensor 309 senses the approach of the moving block 304, thereby controlling the second servo motor 302 to reverse, so that the first threaded rod 303 drives the moving block 304 to move in the opposite direction. When the moving block 304 moves the first threaded rod 303 away from one end of the blocking block 310, the second servo motor 302 reverses again, and this reciprocating process is finally achieved to achieve the closing of the voice coil wire.
