A VCM coil winding system

Abstract

A VCM coil winding system includes a frame, a three-dimensional driving mechanism, a wire starting clamping mechanism, a tinning mechanism, a winding mechanism, a hot air mechanism, and a control module. The control module controls the three-dimensional driving mechanism to drive the wire so that the wire starting clamping mechanism clamps the wire. After the wire starting clamping mechanism clamps the wire, the control module controls the tinning mechanism to tin the wire between the wire starting clamping mechanism and the three-dimensional driving mechanism. After the wire is tinned, the control module controls the wire starting clamping mechanism and the three-dimensional driving mechanism to bring the wire close to the VCM coil skeleton and wind the wire around the corresponding position of the VCM coil skeleton while the spindle assembly rotates. After the wire is tinned and before the wire is wound, the control module controls the hot air gun to blow hot air at the winding position of the VCM winding skeleton. Under the control of the control module, the VCM coil winding system can automatically complete the full process winding of the VCM coil.

Description

Technical Field

[0001] The present invention relates to the technical field of mechanical equipment, and in particular to a VCM coil winding system. Background Art

[0002] VCM motor, or voice coil motor, is a motor that converts electrical energy into mechanical energy and achieves linear or limited swing angle motion. It is mainly used for small stroke, high speed, and high acceleration motion. It can be divided into two types according to the operation mode: linear and swing. The swing VCM motor is also called a galvanometer motor. It is widely used in optical lenses and is suitable for use as a lens focusing driver in narrow spaces such as mobile phone cameras. The coil is wound on the bobbin on the side of the galvanometer motor. The interaction between the magnetic field from the permanent magnet and the magnetic poles in the magnetic field generated by the power supply of the coil conductor produces regular motion. Therefore, the winding of the coil is very important to control its accuracy.

[0003] Traditional coil winding is done manually, which is inefficient and has poor precision. It is also done by mechanized production using mold clamping. However, due to the small size of the motor, the mold structure is designed to be miniaturized, making it difficult to achieve accurate positioning during assembly. In order to realize the automation of the VCM coil winding system, it is necessary to design various functional modules that can enable the winding machine to successfully automate the winding process, and to organically assemble the various functional modules together to achieve automation. Summary of the invention

After the wire is tinned, the control module controls the wire-starting clamping mechanism and the three-dimensional driving mechanism to move the wire close to the VCM coil frame and wind the wire around the corresponding position of the VCM coil frame while the spindle assembly rotates. After the wire is tinned and before the wire winding is completed, the control module controls the hot air gun to blow hot air at the winding position of the VCM coil frame.

[0025] The specific embodiments of the present invention are further described in detail below. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0026] like Figures 1 to 9 As shown, it is a schematic diagram of the structure of the VCM coil winding system provided by the present invention. The VCM coil winding system includes a frame 10, at least one bobbin 20 arranged on the frame 10, at least one tensioner 30 mounted on the frame 10, a three-dimensional driving mechanism 40 arranged on the frame 10, a wire starting clamping mechanism 50 arranged on the frame 10, a tinning mechanism 60 arranged on the frame 10, a winding mechanism 70 arranged on the frame 10, a hot air mechanism 80 arranged on the frame 10, and a control module 90 that controls the three-dimensional driving mechanism 40, the wire starting clamping mechanism 50, the tinning mechanism 60, the winding mechanism 70 and the hot air mechanism 80 to work in an orderly manner. It can be imagined that the VCM coil winding system also includes some other functional modules, such as an assembly component that assembles the above-mentioned functional modules together, an electrical connection component, etc., which are technologies known to those skilled in the art and are not described in detail one by one here.

[0027] The rack 10 is used to carry the above-mentioned functional modules, and its structure and shape can be designed according to actual needs, which will not be described in detail here.

[0028] The wire drum 20 is used to store the wire for winding, and is in a cylindrical shape and can rotate on the frame 10 to deliver the stored wire.

[0029] The tensioner 30 itself is a prior art, which is used to provide a certain tension force for the output wire so that it can be tightly wound on the VCM coil frame. The VCM coil frame is a prior art, which has protrusions on both sides for winding the wire.

[0030] The three-dimensional driving mechanism 40 includes an X-axis sliding mechanism 41, a Y-axis sliding mechanism 42 mounted on the X-axis sliding mechanism 41, a Z-axis sliding mechanism 43 arranged on the Y-axis sliding mechanism 42, and at least one wire guide pin 44 arranged on the Z-axis sliding mechanism 43. The X-axis sliding mechanism 41, the Y-axis sliding mechanism 42, and the Z-axis sliding mechanism 43 have basically the same structure, that is, they all include a driving motor, a guide rail, and a base frame, etc., which will not be repeated here. The wire guide pin 44 is arranged at one end of the Z-axis sliding mechanism 43, and is used to pass the wire through and allow the wire to pass through smoothly.

[0031] The wire-starting clamping mechanism 50 includes a two-dimensional driving assembly 51 arranged on the frame 10, a setting rod 52 arranged on the two-dimensional driving assembly 51, and at least one clamping mechanism 53 arranged on the setting rod 52. The two-dimensional driving assembly 51 includes two linear cylinders whose driving directions are perpendicular to each other. The linear cylinder should be a prior art, which moves linearly under the action of pneumatics. The setting rod 52 is arranged on one of the two linear cylinders, so that it can move forward, backward, left and right under the drive of the two-dimensional driving assembly 51. The length of the setting rod 52 can be set according to actual needs. The clamping mechanism 53 includes a base plate 531 arranged on the setting rod 52, a rotating plate 532 rotatably arranged on the base plate 531, a rotating cylinder 533 fixedly arranged on the rotating plate 532 and used to drive the rotating plate 532 to rotate, and a clamping claw 534 arranged on the rotating plate 532. The setting positions of the base plate 531 and the rotating plate 532 can be set according to actual needs. The base plate 531 is arranged on the erection rod 52 and is fixed. The rotating plate 532 and the rotating cylinder 533 are respectively arranged on both sides of the base plate 531, and the rotating cylinder 533 is fixed on the base plate 531. The rotating plate 532 is controlled to rotate by the output end of the rotating cylinder 533. The clamping claw 534 includes a cylinder arranged on the rotating plate 532 and a clamping claw driven by the cylinder. The cylinder drives the clamping claw to open or close so as to release or clamp the wire. When the clamping claw clamps the wire, the tinning and winding actions can be performed together with the three-dimensional driving mechanism 40 under the control of the control module 90. When the clamping claw releases the clamping of the wire, the clamped wire can be thrown into the waste bin.

[0032] The tinning mechanism 60 includes a multi-dimensional driving mechanism 61 arranged on the frame 10, a rack 62 arranged on the multi-dimensional driving mechanism 61, and at least one tinning furnace 63 arranged on the rack 61. The multi-dimensional driving mechanism 61 can be a two-dimensional drive or a three-dimensional drive. In this embodiment, the multi-dimensional driving mechanism 61 is a three-dimensional drive and includes three mutually perpendicular arrangements to achieve movement in the three directions of X, Y, and Z. To complete this task, the multi-dimensional driving mechanism 61 has three linear motors, which are arranged perpendicular to each other. The rack 62 is arranged on the multi-dimensional driving mechanism 61, and its shape and structure can be set according to actual needs. The tinning furnace 63 includes a base 631 arranged on the rack 62, a heating furnace 632 spaced apart from the base 631, and a tinning rod 633 arranged on the base 631. The base 631 is fixedly arranged on the rack 62. The heating furnace 632 is spaced apart from the base 631 to prevent the heat of the heating furnace 632 from being conducted away. The heating furnace 632 includes a body 634 and a tin melting tank 635 opened on the body 634. It is conceivable that the heating furnace 632 also includes a heating device for heating and melting the solder in the tin melting tank 635. The tin melting tank 635 includes a tin-applying surface 6351, a yielding surface 6352 arranged on the side of the tin-applying surface 6351, and a tin-scraping surface 6353 spaced apart from the tin-applying surface 6351. The tin-passing direction of the wire is perpendicular to the arrangement direction of the tin-applying surface 6351 and the tin-scraping surface 6353. The tin-applying surface 6351 and the tin-scraping surface 6353 are spaced apart to form a step. When the solder in the tin melting tank 635 melts, it will form an arc on the tinning surface 6351 under the action of surface tension. When the wire passes through the arc, the molten solder can adhere to the wire, and the wire will not contact the side wall of the tinning surface 6351. In order to ensure that the wire does not contact the side wall of the tinning surface 6351, a clearance surface 6352 is also provided on one side of the tinning surface 6351. The clearance surface 6352 is an inclined surface. The tin scraping surface 6353 is used to scrape off the oxide layer on the solder with a tool after it is melted for welding. The tin stripping rod 633 is arranged in the arrangement direction of the clearance surface 6352 and the tinning surface 6351, and the clearance surface 6352 is located between the tin stripping rod 633 and the tinning surface 6351. The soldering rod 633 is used to move the soldered wire, and includes a straight section 6331 crimping the wire and an arc section 6331 for detaching from the straight section 6331. The straight section 6331 is spaced apart from the soldering surface 6351, so that the wire is located between the soldering surface 6351 and the straight section 6331.Specifically, first, the wire passes through the tin surface of the tinning surface 6351, but it is inevitable that the oxide layer will be stained. Therefore, the wire is lifted by the outlet guide needle 44 of the multidimensional driving mechanism 40 and the wire starting clamping mechanism 63 and abuts the straight segment 6331 until the wire is deformed under the pressure of the straight segment 6331, and then when the straight segment 6331 is driven by the multidimensional driving mechanism 61 to break away from the abutment with the wire, the wire will vibrate in the process of returning to its original shape, that is, the straight shape, so that the attached oxide layer will be ejected and fall off, achieving the purpose of removing the oxide layer. The multidimensional driving mechanism 61 drives the tinning furnace 63 to tin the starting end of the wire under the control of the control module 90. It can be imagined that the same method can be used to tin the tail end of the wire. It is precisely because of the design of the tinning mechanism 60 that the automation of tinning is achieved, making it possible for the VCM coil winding machine to automatically complete the entire VCM coil.

[0033] The winding mechanism 70 includes a base 71 disposed on the frame 10, a driving assembly 72 disposed on the base 71, a skeleton fixture 73 disposed on the driving assembly 72, a main shaft positioning mechanism 74 disposed on the driving assembly 72, a secondary shaft positioning mechanism 75 disposed on the driving assembly 72, and a winding transposition mechanism 76 that drives the skeleton fixture to rotate 180 degrees. The base 71 is fixedly disposed on the frame 10, and a plurality of mounting holes can be disposed thereon. The plurality of mounting holes are respectively used to mount a plurality of components of the driving assembly 72. It can be imagined that the plurality of mounting holes should have a high degree of coaxiality so that the driving assembly 72 can work normally. The driving assembly 72 includes a main shaft mechanism 721 disposed on the base 71, a secondary shaft mechanism 722 disposed on the base 71 and spaced apart from the main shaft mechanism 721, a driving device 723 disposed on the base 71 and driving the main shaft mechanism 721 and the secondary shaft mechanism 722 to rotate at the same time, and a reciprocating driving mechanism 724 driving the secondary shaft mechanism 722 to move away from or close to the main shaft mechanism 721. The main shaft mechanism 721 includes a main shaft 7211 and a main bearing assembly 7212 disposed on the base 71. The main shaft 7211 is used to set a part of the skeleton jig 73 and rotates under the drive of the driving device 73, so as to wind the wire around the VCM coil skeleton fixed on the skeleton jig 73. The bearing assembly 7212 includes a sleeve, a bearing, a clamping plate, a fixing ring, etc., which are prior arts and will not be described in detail here. The secondary shaft mechanism 722 includes a secondary shaft 7221, a secondary bearing assembly 7222 disposed on the base 71, and a secondary follower gear 7223 passing through the secondary shaft 7221. The secondary shaft 7221 is used to fix another part of the skeleton fixture 73 and rotate under the drive of the driving device 73. The secondary shaft 7221 is provided with a plurality of grooves 7224 along its axial direction, and the secondary follower gear 7223 is provided with a convex strip 7225 coupled with the plurality of grooves 7224. Therefore, when the secondary follower gear 7223 rotates, the secondary shaft 7221 can be driven to rotate. The secondary bearing assembly 7221 also includes a sleeve, a bearing clamp, a fixing ring, etc., which are prior art and are not described here. The difference between the primary and secondary bearing assemblies 7212 and 7221 is that the secondary bearing assembly 7221 includes a sliding sleeve 7226. The sliding sleeve 7226 is disposed between the sleeve and the bearing clamping plate, and is fixed to a fixing ring, etc., so that when the sliding sleeve 7226 moves forward and backward, it can drive the secondary shaft 7221 to move forward and backward. The driving device 723 includes a driving shaft 7231 passing through the base 71, and two driving gears 7232 respectively disposed at both ends of the driving shaft 7231.The two driving gears 7232 are connected to the main shaft mechanism 721 and the secondary shaft mechanism 722 respectively to drive the main shaft mechanism 721 and the secondary shaft mechanism 722 to rotate simultaneously. One of the driving gears 7232 is connected to the gear of the main shaft mechanism 721 through a belt, thereby driving the main shaft 7211 to rotate. The other of the driving gears 7232 is connected to the secondary follower gear 7223 of the secondary shaft mechanism 722 through a belt, thereby driving the secondary shaft 7221 to rotate. The main and secondary shafts 7211 and 7221 can be driven to rotate simultaneously and in the same direction through the driving device 723, so that the wire can be wound on the VCM coil frame. The reciprocating driving mechanism 724 includes a bracket assembly 7241 arranged on the base 71, a screw rod 7242 movably arranged on the bracket assembly 7241, and a driving plate 7243 screwed to the screw rod 7242. The support assembly 7241 may include, for example, a mounting plate, a mounting guide column, etc., which are prior art and will not be described in detail herein. The screw 7242 is arranged on the support assembly 7241 through a sliding assembly such as a bearing, so that it can rotate under the drive of a motor. The drive plate 7243 is screwed to the screw 7242, so that when the screw 7242 rotates, the drive plate 7243 can be driven to rotate. The drive plate 7243 is fixedly connected to the sliding sleeve 7226, so that when the drive plate 7243 moves forward and backward, the sliding sleeve 7226 can be driven to move forward and backward, thereby driving the secondary shaft 7221 to move forward and backward. The secondary follower gear 7223 is fixedly arranged relative to the support assembly 7241 in the axial direction. Specifically, the secondary follower gear 7223 is fixedly arranged on the mounting plate of the support assembly 7241 through a sliding bearing assembly, and it can only rotate but cannot move along its axial direction. Through the above-mentioned structural setting, a part of the skeleton fixture 73 arranged on the secondary shaft 7221 and another part of the skeleton fixture 73 arranged on the main shaft 7211 can achieve the purpose of closing and separating, so that winding can be carried out when closing, and material can be taken or loaded when separating, which helps to realize automated winding.

[0034] The skeleton jig 73 is used to clamp the VCM coil skeleton to facilitate winding. Since the wire is wound on the side of the VCM coil skeleton, two jigs are required to abut it for winding. In this embodiment, the skeleton jig 73 includes a main jig 731 arranged on the main shaft 7211, and a sub-jig 732 arranged on the sub-shaft 7221.

[0035] The main shaft positioning mechanism 74 and the secondary shaft positioning mechanism 75 have the same structure, which is used to position the main shaft 7211 and the secondary shaft 7221 at the same angle or position, so that the abutment between the main fixture 731 and the secondary fixture 732 can maintain its consistency and avoid misalignment. The main shaft positioning mechanism 74 and the secondary shaft positioning mechanism 75 include a fixed fixed seat 741, a positioning groove 742 arranged in the fixed seat 741, and a positioning tooth 743 respectively arranged on the main shaft mechanism 721 and the secondary shaft mechanism 722. The fixed seat 741 can be arranged on the base 71 or on the driving plate 7243. The positioning groove 742 is arranged in the fixed seat 741 and has a V-shaped groove. It can be imagined that the positioning groove 742 is driven by a cylinder to reciprocate to achieve coupling or separation with the positioning tooth 743. The positioning tooth 743 has a V-shaped tooth that matches the positioning groove 742. When the main and auxiliary shafts 7211 and 7221 are fixed, such as when taking or loading materials, the main and auxiliary shaft positioning mechanisms 74 and 75 fix the relative positions of the main and auxiliary shafts 721 and 722 to prevent the main and auxiliary fixtures 731 and 732 from being misaligned with each other and failing to abut correctly.

[0036] The winding transposition mechanism 76 includes a driver 761 disposed on the bracket 10, a support rod 762 disposed on the driver 761, and at least one rotating mechanism 763 disposed on the support rod 761. The driver 761 can be a cylinder, which drives the support rod 762 to move up and down, and realizes the engagement and separation of the rotating mechanism 763 with the main fixture 731. The rotating mechanism 763 includes a support 764 disposed on the support rod 761, a rotating device 765 fixedly disposed on the support 764, and a transposition handle 766 driven by the rotating device 765. The rotating device 765 can be a rotating cylinder, which rotates the transposition handle 766 to rotate 180 degrees, thereby driving the main fixture 731 to rotate 180 degrees, and then the coil winding on the other side of the VCM coil skeleton can be realized, so that the winding automation can be realized.

[0037] The hot air mechanism 80 includes a bracket 81 disposed on the frame 10, a slide rail mechanism 82 disposed on the bracket 81, and a hot air gun 83 mounted on the slide rail mechanism 82. The bracket 81 is used to support the slide rail mechanism 82, and the angle between the axial direction of the bracket 81 and the axial direction of the spindle assembly 72 is an acute angle, so that the hot air gun 83 can be inserted between the spindle assemblies 72. The slide rail mechanism 82 is a prior art, which drives the hot air gun 83 to blow hot air onto the VCM coil on the skeleton fixture 82.

[0038] The control module 90 is electrically connected to the three-dimensional driving mechanism 40, the wire holding mechanism 50, the tinning mechanism 60, the winding mechanism 70, and the hot air mechanism 80 to provide control signals to each of the above modules to achieve automatic winding.

[0039] After the winding is completed, since the wire in the VCM coil frame is usually very thin, after the winding is completed, the wire between the wire holding mechanism 50 and the VCM coil can be pushed against by the wire guide pin 44, and the wire between the wire holding mechanism 50 and the VCM coil can be torn off. At the same time, for the wound VCM coil, when taking the wound coil, it only takes a manual pull to tear the wire off, thereby completing the winding of the VCM coil.

[0040] The VCM coil winding system also includes a waste recovery drum 11 arranged on the frame 10. After the wire on the wire clamping mechanism 50 is broken, the clamping mechanism 53 puts the clamped wire into the waste recovery drum 11 under the control of the control module 90.

[0041] Compared with the prior art, the VCM coil winding system provided by the present invention first clamps the starting wire of the wire by the starting wire clamping mechanism 50 through the three-dimensional driving mechanism 40, and then moves the wire to the tinning mechanism 60 through the control of the control module 90, and the starting wire clamping mechanism 50 and the three-dimensional driving mechanism 40, and the tinning mechanism 60 tins the starting wire position of the wire. After tinning, the winding mechanism 70 winds the VCM coil skeleton clamped on the skeleton fixture 73, and the hot air mechanism 80 blows hot air to the wound coil while winding, so that the wire is softened and tightly closed together. After the winding is completed, the wire cutting mechanism finally cuts the starting wire and the tail wire of the VCM coil under the control of the control module, thereby completing the winding of the VCM coil. Under the control of the control module, the present invention can automatically complete the full process winding of the VCM coil.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention is included in the scope of the claims of the present invention.
