Description

Technical Field

[0002] With the continuous development of science and technology, the functions of mobile smart devices have increased, the size of their internal components has decreased, and the requirements for installation precision have increased. VCM coils are often used as drivers for lens focus adjustment in mobile smart devices, and their importance is self-evident.

[0003] Winding is a critical step in the production of VCM coils, and controlling winding precision is crucial. Traditional VCM coil winding processes rely on either manual labor, which is inefficient and inaccurate, or mechanized production using mold clamping. However, due to the small size of VCM coils, the mold structure is correspondingly miniaturized, making accurate positioning difficult during assembly.

[0027] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0028] As shown in the figure, a fully automatic VCM coil winding device includes a jig forward and backward motion mechanism 2, a winding rotation mechanism 3, a fine-tuning mechanism 4, a jig drive rotation mechanism 5, a wire pulling and winding mechanism 7, and a heating mechanism 6, located on a base 1. The base 1 has a nearly U-shaped structure, which facilitates the arrangement of the jig forward and backward motion mechanism 2, the winding rotation mechanism 3, the fine-tuning mechanism 4, the jig drive rotation mechanism 5, the wire pulling and winding mechanism 7, and the heating mechanism 6. The base 1 is provided with multiple thread holes for connecting to the jig forward and backward motion mechanism 2, the winding rotation mechanism 3, the fine-tuning mechanism 4, the jig drive rotation mechanism 5, the wire pulling and winding mechanism 7, and the heating mechanism 6. The jig forward and backward motion mechanism 2, the winding rotation mechanism 3, the fine-tuning mechanism 4, the jig drive rotation mechanism 5, the wire pulling and winding mechanism 7, and the heating mechanism 6 are provided with mounting slots corresponding to the thread holes. The mounting slots facilitate the positional adjustment of the jig forward and backward motion mechanism 2, the winding rotation mechanism 3, the fine-tuning mechanism 4, the jig drive rotation mechanism 5, the wire pulling and winding mechanism 7, and the heating mechanism 6. The bottom of the base 1 is designed with pin holes for positioning. The base 1 is made of ductile iron casting, which is first heat-treated to reach a certain hardness and then painted to make its surface more beautiful.

[0029] The jig forward and backward motion mechanism 2 is fixed to the outside of one side panel of the base 1. One end of the winding rotation mechanism 3 is fixed to the other side panel of the base 1, and the other end of the winding rotation mechanism 3 is fixed to the sliding plate 204 of the jig forward and backward motion mechanism 2. The jig forward and backward motion mechanism 2 can move the two ends of the winding rotation mechanism 3 closer or farther from each other, thereby moving the VCM skeleton jig on the fine-tuning mechanism 4 back and forth to the designated winding area. The fine-tuning mechanism 4 is fixed to the main shaft rotation rod 303 of the winding rotation mechanism 3 and can precisely adjust the position of the VCM skeleton jig to ensure the winding accuracy of the VCM coil. The jig drive rotation mechanism 5 is fixed to the bottom plate of the base 1 and located below the fine-tuning mechanism 4. The jig drive rotation mechanism 5 provides power for the jig's rotation. The heating mechanism 6 and the wire pulling and winding mechanism 7 are adjacently arranged on one end surface of the base 1. The heating mechanism 6 is used to heat the product during the winding process, and the wire pulling and winding mechanism 7 is used to break the outgoing wire and wind the waste wire.

[0030] The jig's forward and backward motion mechanism 2 includes a horizontal support, which includes a support rod 201, a first fixed plate 202, a second fixed plate 203, and a sliding plate 204. The support rods 201 are provided with at least two, each perpendicularly connected to a side plate of the base 1. The first fixed plate 202, the second fixed plate 203, and the sliding plate 204 are arranged in sequence and parallel to a side plate of the base 1. The first fixed plate 202 and the second fixed plate 203 are both fixedly connected to the support rod 201, and the sliding plate 204 is slidably connected to the support rod 201 between the second fixed plate 203 and the base 1. A first rotary power device 205 is provided on the first fixed plate 202. The first rotary power device 205 is a servo motor and is connected to a ball screw 207 via a coupling 206 on the second fixed plate 203. The other end of the ball screw 207 is rotatably connected to the base 1, and the first rotary power device 205 can drive the ball screw 207 to rotate. The nut sleeve on the ball screw 207 is connected to the sliding plate 204, and the ball screw 207 can provide power for the reciprocating movement of the sliding plate 204 on the support rod 201. A connecting rod 208 is fixed between the second fixed plate 203 and the base 1. The horizontal elongated hole of the connecting rod 208 is connected to the first photoelectric sensor 209 through a connecting seat. A light shield 210 is provided on the side of the sliding plate 204 near the first photoelectric sensor 209. The light shield 210 matches the gap between the transmitter and receiver of the first photoelectric sensor 209. The photoelectric sensor serves as the origin of movement. When the light shield 210 moves to the first photoelectric sensor 209 as the sliding plate 204 moves, the receiver is blocked by the light shield 210 and cannot receive the light emitted by the transmitter. The receiver transmits this signal to the controller, which determines that the sliding plate 204 and the winding rotation mechanism 3 are at the origin of movement. At this point, the controller can easily determine the rotation amount of the first rotary power device 205 to achieve precise control of the movement distance of the sliding plate 204 and the winding rotation mechanism 3.

[0031] The winding rotation mechanism 3 includes a second rotary power device 301, a ball spline 302, a main shaft rotating rod 303 and a secondary shaft rotating rod 304. The second rotary power device 301 is horizontally connected to the base 1 through a mounting bracket. The second rotary power device 301 is a high-inertia servo motor. The ball spline 302 is arranged parallel to the bottom of the main shaft rotating rod 303, and the secondary shaft rotating rod 304 is located on the same horizontal line as the main shaft rotating rod 303. The main shaft rotating rod 303 is rotatably connected to the sliding plate 204. Specifically, the sliding plate 204 can be provided with a main shaft sliding sleeve, and the main shaft sliding sleeve is installed with a precision angular contact bearing. The inner ring of the precision angular contact bearing is mounted with the main shaft rotating rod 303. The end of the main shaft rotating rod 303 away from the secondary shaft rotating rod 304 is connected to the first synchronous wheel 305, and the end of the main shaft rotating rod 303 close to the secondary shaft rotating rod 304 is connected to the fine-tuning mechanism 4. The secondary shaft rotating rod 304 is rotatably connected to the base 1. The end of the secondary shaft rotating rod 304 closest to the main shaft rotating rod 303 is connected to the second synchronous wheel 306. The first synchronous wheel 305 and the second synchronous wheel 306 are both tightened with lock nuts to prevent deviation. The two ends of the ball spline 302 pass through the two side plates of the base 1 respectively. One end of the ball spline 302 is connected to the output shaft of the second rotary power device 301, and the second rotary power device 301 can drive the ball spline 302 to rotate. The other end of the ball spline 302 is rotatably connected to the sliding plate 204 via a spline sleeve. The spline sleeve enables the sliding plate 204 to slide on the spline shaft of the ball spline 302. The ball spline 302 is provided with a first drive wheel 307 and a second drive wheel 308. The first drive wheel 307 is correspondingly disposed below the first synchronous wheel 305, and the second drive wheel 308 is correspondingly disposed below the second synchronous wheel 306. The first drive wheel 307 and the second drive wheel 308 are capable of rotating in response to the rotation of the ball spline 302. The first drive wheel 307 and the first synchronous wheel 305, as well as the second drive wheel 308 and the second synchronous wheel 306, are connected by a belt 309. The belt 309 can transmit power from the first drive shaft and the second drive shaft to the first synchronous wheel 305 and the second synchronous wheel 306, thereby enabling the first synchronous wheel 305 to rotate the main shaft rotating rod 303, and the second synchronous wheel 306 to rotate the countershaft rotating rod 304.

[0032] The fine-tuning mechanism 4 includes a winding jig head 401, an adjustment block 402, and a jig seat 403. The winding jig head 401 is fixedly connected to the spindle rotating rod 303. A connecting slot 404 is provided at the end of the winding jig head 401 away from the spindle rotating rod 303. The adjusting block 402 is located within the connecting slot 404 and is movable along the length of the connecting slot 404. The adjusting block 402 is provided with a vertical guide rail, and the jig seat 403 is located on the guide rail. The jig seat 403 is movable along the length of the guide rail. The top, bottom, and sides of the connecting slot 404 are fixedly connected to a fixed block 405. The fixed block 405 is detachably connected to the winding jig head 401 via bolts, facilitating maintenance and replacement of the fixed block 405. Each of the four fixed blocks 405 is equipped with an adjustment screw 406. These round-head screws can minimize damage to the adjustment block 402 and the fixture base 403. The adjustment screws 406 on the two fixed blocks 405 located on either side of the connection slot 404 are connected to the sides of the adjustment block 402, respectively. Adjusting these two adjustment screws 406 allows the adjustment block 402 to move, thereby changing its position on the connection slot 404. The adjustment screws 406 on the two fixed blocks 405 located at the top and bottom of the connection slot 404 are connected to the top and bottom of the fixture base 403, respectively. Adjusting these two adjustment screws 406 allows the fixture to move, thereby changing the position of the fixture base 403 on the adjustment block 402. In summary, adjusting the four adjustment screws 406 can fine-tune the vertical, horizontal, and vertical position of the fixture base 403, thereby achieving precise adjustment of the VCM skeleton fixture position. A first limiting rod 407 is provided on one of the fixed blocks 405, and the first limiting rod 407 is arranged parallel to the top of the jig seat 403. The first limiting rod 407 is provided with a first limiting groove evenly distributed along its length direction. The first limiting groove is used to limit the wire. After the wire is wound on the first limiting groove at a specific position, it can prevent the wire from deviating during the winding process, thereby ensuring the accuracy and stability of the winding process.

[0033] The fixture drive rotation mechanism 5 includes a lifting power unit base 501, a first lifting power unit 502, a mounting plate 503, a third rotation power unit 504, and a fixture rotating base 505. The lifting power unit base 501 is fixedly connected to the top surface of the bottom plate of the base 1. The lifting power unit base 501 is equipped with the first lifting power unit 502, which is a CD-axis cylinder. The first lifting power unit 502 is connected to the mounting plate 503 and can drive the mounting plate 503 to move up and down. One end of the mounting plate 503 is connected to a lifting limit post 506 on the support base, which can limit the lifting height of the mounting plate 503. The top surface of the other end of the mounting plate 503 is equipped with an adjacent fixture rotating base 505 and a second photoelectric sensor 507. The bottom surface of the other end of the mounting plate 503 is equipped with the third rotation power unit 504 connected to the fixture rotating base 505. The third rotary power unit 504 is a rotary stepper motor that drives the jig rotating base 505 to rotate. The jig rotating base 505 has a central boss with a slot 508 that plugs into the VCM skeleton jig, allowing the jig rotating base 505 to rotate the VCM skeleton jig. The jig rotating base 505 is provided with a radially extending slot 509 that matches the gap between the transmitter and receiver of the second photoelectric sensor 507. The combination of slot 509 and the second photoelectric sensor 507 allows the jig rotating base 505 to detect the number of revolutions, thereby ensuring the accuracy of the number of windings.

[0034] The heating mechanism 6 includes a heat gun fixing block 601, a heat gun 604 mounting plate 602, a translational force device 603, and a heat gun 604. The heat gun fixing block 601 is vertically fixed to the end face of the machine base. The top of the heat gun fixing block 601 is provided with a heat gun 604 mounting plate 602. The top surface of the heat gun 604 mounting plate 602 is provided with a fixed seat and a sliding seat arranged adjacent to each other. The fixed seat is provided with a translational force device 603. The translational force device 603 is a pen-shaped cylinder connected to the sliding seat and can drive the sliding seat to reciprocate. The sliding seat is slidably arranged within a linear guide on the heat gun 604 mounting plate 602. The linear guide ensures the stability of the sliding seat during movement. The sliding seat is provided with a heat gun 604, and an insulation sleeve is provided between the heat gun 604 and the sliding seat. The insulation sleeve can prevent burns on the sliding seat and shorten its service life. The hot air gun head of the hot air gun 604 is square, and the square hot air gun head can make the hot air more concentrated.

[0035] The wire pulling and winding mechanism 7 includes an L-shaped mounting base 701, a multi-position mounting cylinder 702, left and right cylinder mounting plates 703, a slide cylinder 704, and a waste wire sleeve mounting block 705. The vertical portion of the L-shaped mounting base 701 is connected to the base 1. The horizontal portion of the L-shaped mounting base 701 is provided with a multi-position mounting cylinder 702 and left and right cylinder mounting plates 703 located on a guide rail. The guide rail and the multi-position mounting cylinder 702 are both perpendicular to the folded edge of the L-shaped mounting plate 503. The multi-position mounting cylinder 702 is connected to the left and right cylinder mounting plates 703. The multi-position mounting cylinder 702 can drive the left and right cylinder mounting plates 703 to move back and forth smoothly on the guide rail. A slide cylinder 704 is fixed to the sides of the left and right cylinder mounting plates 703. This slide cylinder 704 is parallel to the folded edge of the L-shaped mounting plate 503. The end of the telescopic rod of the slide cylinder 704 is connected to the waste wire sleeve mounting block 705, enabling the slide cylinder 704 to reciprocate. A waste wire box 706 is fixed to one side of the horizontal plate of the waste wire sleeve mounting block 705. The bottom surface of the horizontal plate of the waste wire sleeve mounting block 705 is connected to the second lifting power unit 707. The top surface of the horizontal plate of the waste wire sleeve mounting block 705 is provided with adjacent guide cylinders 708 and second limiting posts 709. The guide cylinder 708 is connected to a slanted plate on the waste wire box 706. The height of the slanted plate gradually increases from the end closest to the waste wire box 706 to the end farther away from the waste wire box 706, guiding the waste wire into the waste wire box 706. A waste wire winding post 710 connected to a second lifting power unit 707 is installed within the guide cylinder 708. The second lifting power unit 707 can drive the waste wire winding post 710 to rise and fall. When the waste wire winding post 710 descends, the guide cylinder 708 can pull the waste wire off the waste wire winding post 710 and then guide it through the inclined plate into the waste wire box 706. A second limiting post 709 is arranged near the winding rotation mechanism 3 and is provided with second limiting grooves evenly distributed along its height. The second limiting grooves can limit the position of the wire, ensuring the stability and accuracy of the position of the wire during winding.

[0036] When in use, the wire end on the wire feeding device is wound on the waste wire winding column 710, the VCM skeleton jig is placed on the jig seat 403 of the fine-tuning mechanism 4, and then the position of the VCM skeleton jig is precisely adjusted using the four adjusting screws 406. Start the first rotary power device 205 on the jig forward and backward motion mechanism 2 to return the VCM skeleton jig to its original position. When the receiver on the first photoelectric sensor 209 fails to receive the light emitted by the transmitter, it indicates that the VCM skeleton jig has returned to its initial position. Lead the wire from the waste wire winding column 710 and wind it around the winding area of the VCM skeleton jig. Determine the rotation amount of the first rotary power device 205 and start the first rotary power device 205 to make the VCM skeleton jig contact the secondary shaft rotating rod 304 to ensure that both ends of the winding area on the VCM skeleton jig have obstructions during the winding process, thereby preventing the phenomenon of derailment and collapse of the wire during the winding process. Start the second rotary power device 301 on the winding rotation mechanism 3 or the third rotary power device 504 on the jig driving rotation mechanism 5 to drive the VCM skeleton. The jig rotates for winding, and the coordinated use of the winding rotation mechanism 3 and the jig drive rotation mechanism 5 can facilitate winding on multiple surfaces of the VCM skeleton jig. When the winding rotation mechanism 3 is winding, the second rotary power device 301 controls the winding speed of the VCM skeleton jig, and the first rotary power device 205 controls the horizontal movement speed of the VCM skeleton jig to improve the accuracy of winding in the horizontal direction. When the jig drive rotation mechanism 5 is winding, the third rotary power device 504 controls the winding speed of the VCM skeleton jig, and the second photoelectric sensor 507 determines the number of winding turns to improve the accuracy of winding in the vertical direction. During the winding process, the hot air gun 604 in the heating mechanism 6 is started to heat the wire on the VCM skeleton jig. The entire process of winding the wire greatly reduces the amount of manual operation and improves production efficiency.

[0037] Therefore, the present invention adopts the fully automatic VCM coil winding device of the above structure to solve the problems of low VCM coil winding precision and low production efficiency caused by the small size of the VCM coil.
