It is contemplated that the VCM coil winding system further includes other functional modules, such as assembly components for assembling the functional modules, electrical connection components, etc., which are well known to those skilled in the art, and will not be described in detail herein.

The frame 10 is used for carrying the above functional modules, and the structure and shape of the frame can be designed according to actual needs, which are not described herein again.

The bobbin 20 is a tube for accommodating a wire to be wound, and is rotatable on the frame 10 to feed out the accommodated wire.

The tensioner 30 itself is a prior art technique for providing a certain tension to the outgoing wire so that it can be tightly wound around the VCM bobbin. The VCM bobbin is a prior art having protrusions on both sides for winding a wire.

The bridging rod 52 is provided on one of the two linear cylinders so as to be movable back and forth and left and right by the two-dimensional driving assembly 51. The length of the erection rod 52 can be set according to actual needs. The clamping mechanism 53 includes a base plate 531 disposed on the mounting rod 52, a rotating plate 532 rotatably disposed on the base plate 531, a rotating cylinder 533 fixedly disposed on the rotating plate 532 for driving the rotating plate 532 to rotate, and a clamping claw 534 disposed on the rotating plate 532. The positions of the base plate 531 and the rotating plate 532 may be set according to actual requirements. The base plate 531 is fixed to the erection rod 52.

The tinning mechanism 60 comprises a multidimensional driving mechanism 61 arranged on the frame 10, a rack rod 62 arranged on the multidimensional driving mechanism 61, and at least one tinning furnace 63 arranged on the rack rod 61. The multi-dimensional driving mechanism 61 may be a two-dimensional driving or a three-dimensional driving, and in this embodiment, the multi-dimensional driving mechanism 61 is a three-dimensional driving and includes three mutually perpendicular arrangements to realize the motion in three directions X, Y, Z. To accomplish this task, the multi-dimensional driving mechanism 61 has three linear motors, which are arranged perpendicular to each other. The rack bar 62 is disposed on the multi-dimensional driving mechanism 61, and the shape and structure thereof can be set according to actual needs. The upper tin furnace 63 includes a base 631 disposed on the frame bar 62, a heating furnace 632 spaced apart from the base 631, and a tin-poking bar 633 disposed on the base 631. The base 631 is fixedly disposed on the frame bar 62. The heating furnace 632 is spaced apart from the base 631 to prevent heat of the heating furnace 632 from being conducted. The heating furnace 632 includes a body 634, and a molten tin bath 635 formed on the body 634. It is contemplated that the heating furnace 632 further includes a heating device for heating and melting the solder in the solder bath 635. The tin melting tank 635 comprises a tin wetting surface 6351, a receding surface 6352 disposed on a side surface of the tin wetting surface 6351, and a tin scraping surface 6353 disposed at an interval with the tin wetting surface 6351. The tin passing direction of the wire is perpendicular to the arrangement direction of the tin wetting surface 6351 and the tin scraping surface 6353. The tin wetting surface 6351 and the tin scraping surface 6353 are spaced apart from each other, so as to form a step. When the solder in the solder melting tank 635 is melted, it forms an arc on the solder wetting surface 6351 under the action of surface tension, so that the melted solder can adhere to the wire when the wire passes through the arc, and the wire does not contact the sidewall of the solder wetting surface 6351. In order to ensure that the wires do not contact the sidewall of the tin-wetting surface 6351, a relief surface 6352 is further disposed on one side of the tin-wetting surface 6351. The relief surface 6352 is a bevel. The tin scraping surface 6353 is used to scrape an oxide layer on the solder using a tool after melting for soldering. Should tin poking rod 633 sets up on the array direction of abdicating face 6352 and tin sticky surface 6351 just abdicating face 6352 is located between tin poking rod 633 and tin sticky surface 6351. The tin poking rod 633 is used for poking a lead stained with soldering tin and comprises a straight line section 6331 for pressing and connecting the lead and an arc-shaped section 6331 for disengaging from contact with the straight line section 6331. The straight segment 6331 is spaced apart from the tin-wetting surface 6351, so that the wire is located between the tin-wetting surface 6351 and the straight segment 6331. Specifically, the wire firstly passes through the tin surface of the tin-stained surface 6351, but inevitably adheres to the oxide layer, so that the wire is lifted by the wire-outgoing guide pin 44 and the wire-lifting clamping mechanism 63 of the multi-dimensional driving mechanism 40 and abuts against the straight line segment 6331 until the wire deforms under the abutting pressure of the straight line segment 6331, and then when the straight line segment 6331 is driven by the multi-dimensional driving mechanism 61 to be separated from the abutting pressure of the wire, the wire vibrates in the process of recovering the original shape, i.e. the straight line shape, so that the adhered oxide layer is ejected and falls off, and the purpose of removing the oxide layer is achieved. The multidimensional driving mechanism 61 drives the upper tin furnace 63 to perform tin coating for the wire starting end of the lead under the control of the control module 90. It is contemplated that the tail end of the wire may be tinned in the same manner. Due to the design of the tinning mechanism 60, the automation of tinning is achieved, and the VCM coil winding machine can automatically complete the whole VCM coil.

The other of the drive gears 7232 is drivingly connected to a secondary follower gear 7223 of the secondary shaft mechanism 722 via a belt, thereby driving the secondary shaft 7221 for rotation. The driving device 723 can drive the primary and secondary shafts 7211 and 7221 to rotate simultaneously and in the same direction, and thus a wire can be wound around the VCM bobbin. The reciprocating driving mechanism 724 includes a bracket assembly 7241 disposed on the base 71, a screw 7242 movably disposed on the bracket assembly 7241, and a driving plate 7243 threadedly coupled to the screw 7242.

The drive plate 7243 is fixedly coupled to the sliding sleeve 7226 such that when the drive plate 7243 moves forward and backward, the sliding sleeve 7226 and, in turn, the secondary shaft 7221 are driven forward and backward. The secondary follower gear 7223 is axially fixedly disposed relative to the carriage assembly 7241, and in particular, the secondary follower gear 7223 is fixedly disposed on a mounting plate of the carriage assembly 7241 via a plain bearing assembly, which is only rotatable, but not axially movable therealong. Through the structural arrangement, one part of the framework jig 73 arranged on the auxiliary shaft 7221 and the other part of the framework jig 73 arranged on the main shaft 7211 can be folded and separated, so that winding can be performed when the folding is performed, and material can be taken or fed when the folding is performed, and further, automatic winding is facilitated.

The bobbin jig 73 is used for clamping the VCM coil bobbin to facilitate winding. Because the wire is around establishing the side of VCM coil skeleton, consequently need two tools to support it and push up in order to carry out the wire winding. In this embodiment, the frame fixture 73 includes a main fixture 731 disposed on the main shaft 7211, and a sub-fixture 732 disposed on the sub-shaft 7221.

shaft positioning mechanisms

74, 75 fix the relative positions between the primary and
