Technical Field

[0001] The invention relates to the technical field of metal coil manufacturing, in particular to a wire winding and arranging structure. Background Art

[0002] Among the current automated winding equipment, there is no equipment that can wind the starting wire and the tail wire at one time and bend them at any angle and shape them. The existing technology uses manually operated bending jigs and manual operation methods, which are inefficient and the yield cannot be guaranteed. Summary of the invention

[0003] In view of the above problems, the present invention provides a wire winding and wire arranging structure, which enables the starting wire and the tail wire to be reliably bent after the winding is completed, thereby improving the coil production efficiency.

[0004] A wire winding and arranging structure, characterized in that it comprises:

[0005] A winding die, comprising a rotating die set and a driven die set, wherein the driven die set comprises an inner ring, a middle ring and an outer ring, and the driven die set further comprises two sets of ejector pin mechanisms, each set of ejector pin mechanisms comprises an ejector pin end and a driving assembly, and the end surface of the middle ring facing the inner ring is provided with two ejector pin ends arranged at intervals, and an ejector active cavity is provided inside the middle ring and the outer ring, and the ejector pin end has two states of inward contraction and outward protrusion, and the rotating die moves away from or in contact with the inner ring of the driven die set;

[0006] A rotating baffle mechanism, comprising a rotating baffle and a rotating baffle driving mechanism;

[0007] and a wire hooking assembly, which includes a wire hooking clamp and a wire hooking clamp driving mechanism;

[0008] In the winding state, the rotating module is in contact with the inner ring to drive the wire body to wind in a circle;

[0009] After the winding is completed, the rotating baffle is located in the preset activity range of the driving component, and the rotating baffle presses the driving component to drive the ejector needle end to protrude forward and press the starting wire and the tail wire of the inner circle that have been wound, and the starting wire and the tail wire are arranged in parallel and extend to both ends respectively, and each ejector needle end is independently pressed to the tangent point of the starting wire and the tail wire relative to the formed coil;

[0010] The starting line is bent under the rotation of the driven mold, and then the external flying fork drives the tail line to rotate to form a bend. After the starting line and the tail line are bent, they are set toward the area where the wire hook clamp is located. The wire hook clamp clamps the starting line close to the tail line, and the external scissors synchronously cut the starting line and the tail line.

[0011] It is further characterized by:

[0012] The driving assembly comprises a cam follower shaft, an L-shaped transmission member, a compression spring, and two limit rods, wherein the combined position of the inner ring and the middle ring is provided with a guide hole corresponding to the ejector needle end, the top of the L-shaped transmission member is provided with an upwardly convex cam follower shaft, the cam follower shaft is protruding from the outer ring of the outer ring, the L-shaped transmission member is built in the ejector active cavity, the horizontal section of the L-shaped transmission member is provided with two groups of waist-shaped guide holes, and the corresponding limit rods penetrate the waist-shaped guide holes and are fixedly arranged at the corresponding positioning positions of the middle ring and the outer ring, and the ejector active cavity accommodates the L-shaped transmission member to move along the limiting of the two groups of waist-shaped guide holes, the bottom of the L-shaped transmission member is provided with a forwardly convex ejector needle end, and a compression spring is sleeved on the ejector needle end, one end of the compression spring is top-mounted on the bottom front end surface of the L-shaped transmission member, and the other end of the compression spring is top-mounted on the inner stop ring of the guide hole, and the compression spring drives the ejector needle end to retract;

[0013] The rotating baffle is an arc baffle, the arc range of which is greater than the angle corresponding to the bending of the starting line. The arc baffle is pressed against the starting line and the tail line at the front convex of the ejector needle end until the rotating module rotates the set angle so that the starting line bend obtains the corresponding bending position, and is pressed against two sets of cam follower shafts to ensure that the bending of the starting line and the tail line can be carried out reliably;

[0014] The rotating baffle driving mechanism includes a baffle mounting seat, a fixed block, and a first cylinder. The rotating baffle is fixedly provided at the front end of the baffle mounting seat. A linear guide is provided between the fixed block and the baffle mounting seat. The piston end of the first cylinder is fixedly connected to the baffle mounting seat through a connecting plate. The first cylinder drives the baffle mounting seat to move forward or backward along the linear guide. The rotating baffle has two states, including a state of being pressed against a cam follower shaft and a state of being away from the cam follower shaft.

[0015] The wire hooking clamp driving mechanism comprises a wire hooking clamp mounting plate and a second cylinder, one end of the wire hooking clamp mounting plate is fixedly mounted with the wire hooking clamp, and the piston end of the second cylinder is fixedly connected to the other end of the wire hooking clamp mounting plate;

[0016] The moving directions of the first cylinder and the second cylinder are both arranged parallel to the axial direction of the winding module.

[0017] After adopting the above technical scheme, at the beginning of winding, the wire clamp drives the starting wire to wind around the inner circle once and then places the starting wire at the clamping position of the winding equipment to form the starting wire. After that, the product is wound and the ejector needle end is in a retracted state to ensure that it does not affect the normal winding. After the winding is completed, the starting wire and the tail wire are in a 180-degree state. At this time, the tangent points of the starting wire and the tail wire corresponding to the coil are directly below the two ejector needle ends. Then, the rotating baffle driving mechanism is driven to move, so that the rotating baffle moves forward and drives the ejector needle ends to be ejected synchronously. Each ejector needle end is independently pressed against the tangent point of the starting wire and the tail wire relative to the formed coil.

[0018] The starting wire is bent under the rotation of the driven mold, and then the external flying fork drives the tail wire to rotate to form a bend. After the starting wire and the tail wire are bent, they are set toward the area where the wire hook clamp is located. The wire hook clamp clamps the starting wire close to the tail wire, and the external scissors simultaneously cut the starting wire and the tail wire, which can reliably bend the starting wire and the tail wire after the winding is completed, so that the coil production efficiency is high.

DETAILED DESCRIPTION

[0028] A structure for winding and arranging wires, see Figure 1-Figure 6 , which includes a winding mold 10, a rotating baffle mechanism 20, and a wire hooking assembly 30;

[0029] The winding mold 10 includes a rotating module 40 and a driven module 50. The driven module 50 includes an inner ring 51, a middle ring 52, and an outer ring 53. The inner ring 51 has an axial telescopic function. When the inner ring 51 is retracted, it is used for material feeding. When the inner ring 51 is extended, it protrudes outward from the middle ring 52 to perform winding operations. The driven module 53 also includes two groups of ejector mechanisms 60. Each group of ejector mechanisms 60 includes an ejector needle end 61 and a driving assembly 70. Two ejector needle ends 61 are arranged at intervals on the end surface of the middle ring 52 facing the inner ring 51. An ejector active cavity 80 is arranged inside the middle ring 52 and the outer ring 53. The ejector needle end 61 has two states of retraction and protrusion. The rotating module 40 moves away from or fits the inner ring 51 of the driven module 50.

[0030] The driving assembly 70 includes a cam follower shaft 71, an L-shaped transmission member 72, a compression spring 73, and two limit rods 74. The combination position of the inner ring 51 and the middle ring 52 is provided with a guide hole 54 corresponding to the ejector needle end 61. The top of the L-shaped transmission member 72 is provided with an upwardly convex cam follower shaft 71, and the cam follower shaft 71 protrudes from the outer ring of the outer ring 53. The L-shaped transmission member 72 is built into the ejector active cavity 80. The horizontal section of the L-shaped transmission member 72 is provided with two sets of waist-shaped guide holes 75. The corresponding limit rods 74 penetrate through The waist-shaped guide holes 75 are fixedly arranged at the corresponding positioning positions of the middle ring 52 and the outer ring 53. The ejector active cavity 80 accommodates the L-shaped transmission member 72 to move along the limit of the two sets of waist-shaped guide holes 75. The bottom of the L-shaped transmission member 72 is provided with a forward protruding ejector needle end 61. The ejector needle end 61 is sleeved with a compression spring 73. One end of the compression spring 73 is mounted on the bottom front end surface of the L-shaped transmission member 72, and the other end of the compression spring 73 is mounted on the inner stop ring of the guide hole 54. The compression spring 73 drives the ejector needle end 61 to retract.

[0031] The rotating baffle mechanism 20 includes a rotating baffle 21 and a rotating baffle driving mechanism 22. The rotating baffle 21 is an arc baffle. The arc range of the arc baffle is greater than the angle corresponding to the starting line bending. The arc baffle is pressed against the starting line and the tail line when the ejector needle end 61 is protruding forward until the rotating module 40 rotates to a set angle so that the starting line bending obtains the corresponding bending position. The two sets of cam follower shafts 71 are pressed to ensure that the bending of the starting line and the tail line can be carried out reliably.

[0032] The rotating baffle driving mechanism 22 includes a baffle mounting seat 23, a fixing block 24, and a first cylinder 25. A rotating baffle 21 is fixedly arranged at the front end of the baffle mounting seat 23. A linear guide rail 26 is arranged between the fixing block 24 and the baffle mounting seat 23. The piston end of the first cylinder 25 is fixedly connected to the baffle mounting seat 23 through a connecting plate 27. The first cylinder 25 drives the baffle mounting seat 23 to move forward or backward along the linear guide rail 26. The rotating baffle 21 has two states, including a state of being pressed against the cam follower shaft and a state of being away from the cam follower shaft.

[0033] The wire hooking assembly 30 includes a wire hooking clamp 31 and a wire hooking clamp driving mechanism 32. The wire hooking clamp driving mechanism 32 includes a wire hooking clamp mounting plate 33 and a second cylinder 34. The wire hooking clamp 31 is fixedly mounted on one end of the wire hooking clamp mounting plate 33, and the piston end of the second cylinder 34 is fixedly connected to the other end of the wire hooking clamp mounting plate 33.

[0034] The travel directions of the first cylinder 25 and the second cylinder 34 are both arranged parallel to the axis direction of the winding module 10;

[0035] In the winding state, the rotating module 40 is in contact with the inner ring 51 to drive the wire body to wind in a circle, and the ejector needle end 61 is retracted;

[0036] After the winding is completed, the two sets of cam follower shafts 71 are both located within the range of the rotating baffle 21, and the rotating baffle 21 presses the cam follower shaft 71 to overcome the elastic force of the compression spring 73, so that the ejector needle end 61 protrudes forward and presses the starting line and the tail line that have been wound by the inner circle 51. The starting line and the tail line are arranged in parallel and extend to both ends respectively, and each ejector needle end 61 is independently pressed to the tangent point of the starting line and the tail line relative to the formed coil;

[0037] The starting line is bent under the rotation of the driven mold 50, and then the external flying fork drives the tail line to rotate to form a bend. After the starting line and the tail line are bent, they are set toward the area where the wire hook clamp 31 is located. The wire hook clamp 31 clamps the starting line close to the tail line, and the external scissors simultaneously cut the starting line and the tail line.

[0038] For specific implementation, see Figure 7 The bending angles of the starting and tail wires are both 90°, and the operation process is as follows: (1) During product winding, the ejector needle end 61 is supported by the compression spring 73 and is in a retracted state to ensure that normal winding is not affected;

[0039] (2) After the winding is completed, the starting line and the tail line are at a 180° angle, and the first cylinder 25 is pushed out, driving the rotating baffle 21 forward;

[0040] (3) When the rotating baffle 21 moves forward to its position, it pushes the cam follower shaft 71 and drives the ejector needle end 61 to extend (the ejector needle and the cam follower shaft are fixed as one body), and the two points of the ejector needle end 61 press the tangent points of the starting and tail wires of the product with the coil respectively;

[0041] (4) After the ejector needle end 61 extends to the limit position, the rotating module 40 drives the driven module 50 and the product to rotate 90° clockwise, and at the same time, the flying fork drives the tail wire to rotate 90° synchronously, the starting wire is clamped and fixed, and the starting wire is bent 90° with the extension limit point of the lower ejector needle end 61 as the center, and the mold is heated and shaped;

[0042] (5) At this time, the starting line and the tail line are in a 90-degree direction, and the flying fork drives the tail line to continue to rotate 90 degrees clockwise, while the others remain stationary. The tail line is bent 90 degrees with the ejector needle end 61 extending out of the limit point as the center, and the mold is heated and shaped;

[0043] (6) After the folding and arranging of the wires are finalized, the second cylinder 34 moves, driving the wire hook clamp 31 to clamp the starting wire and approach the tail wire, so that the scissors simultaneously cut the starting wire and the tail wire, and the rotating mold set is disengaged, and then the material is unloaded from the mold.

[0044] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
