Description

Technical Field

[0001] This utility model relates to the field of coil manufacturing technology, and in particular to a coil tail wire bending mechanism. Background Technology

[0002] A coil typically refers to a loop of wire winding. The most common applications of coils include motors, inductors, transformers, and loop antennas. In the production of some coils, the starting and ending wires need to be bent at a specific angle. Currently, this bending of the coil's starting and ending wires is mostly done manually, by bending the ends of the coil wire to meet production requirements. This method wastes human resources and cannot guarantee product quality. Utility Model Content

[0003] In view of this, the present invention provides a coil starting and ending wire bending mechanism to solve the above problems.

[0004] A coil starting and ending wire bending mechanism includes a three-axis moving assembly, a wire pulling assembly disposed on one side of the three-axis moving assembly, a bending assembly disposed on one side of the wire pulling assembly, and a winding assembly disposed on one side of the bending assembly. A support plate is provided at the output end of the three-axis moving assembly. The bending assembly includes an X-axis cylinder disposed on the support plate, a Y-axis cylinder disposed at the output end of the X-axis cylinder, a bending cylinder disposed at the output end of the Y-axis cylinder, and two clamping fingers disposed at the output ends of the bending cylinders. The winding assembly includes a lower die, an upper die disposed on one side of the lower die, a wire clamp fixedly disposed on one side of the lower die, a first stop movably disposed on the lower die, and a second stop movably disposed on one side of the first stop. A protrusion is provided on the lower die, and the first and second stops are disposed on one side of the protrusion and make gap contact with the wound coil. The first stop is located between the wound coil and the starting segment of the coil, and the second stop is located at the end of the starting segment of the wound coil near one end of the coil. The movement direction of the first and second stops is parallel to the arrangement direction of the upper and lower dies, and each of the first and second stops is located at the output end of a drive device.

[0005] Furthermore, a guide pin for threading a wire is provided on one side of the support plate, and the length direction of the guide pin is parallel to the arrangement direction of the wire pulling assembly and the folding assembly.

[0006] Furthermore, the wire pulling assembly includes a drive cylinder fixedly mounted on the support plate, a wire pulling cylinder mounted on the output end of the drive cylinder, and two grippers correspondingly mounted on the output ends of the wire pulling cylinder.

[0007] Furthermore, one of the two grippers has a toothed gripping surface, and the other gripper has a spring inside. A gripping block is provided on one side of the spring. The gripping block slides through the gripper, and one end face of the gripping block is toothed and protrudes from the gripper. The gripping block is sleeved on a horizontally arranged guide post, and the toothed surface of the gripping block corresponds to the toothed surface of the gripper.

[0008] Furthermore, one end of the spring abuts against the inner wall of the gripper, and the other end abuts against the clamping block.

[0009] Furthermore, the output direction of the X-axis cylinder is parallel to the output direction of the drive cylinder.

[0010] Furthermore, the output direction of the Y-axis cylinder is perpendicular to the output direction of the X-axis cylinder.

[0011] Compared with existing technologies, the coil tail wire bending mechanism provided by this utility model drives the support plate through the three-axis moving assembly, which in turn moves the wire pulling assembly and the bending assembly, thereby guiding and transferring the wire. After the coil is wound, the first stop rises, and after the lower mold rotates in the opposite direction by a certain angle, the tail wire segment of the coil is bent at a certain angle to the coil. Then the second stop rises, and the clamping fingers in the bending assembly hold the starting wire of the coil and move under the drive of the X and Y axis cylinders, thereby bending the starting wire segment of the coil at a certain angle to the coil. The coil tail wire bending mechanism can bend the starting wire of the coil at a certain angle without manual operation, saving manpower, improving production efficiency, and is suitable for assembly line production.

[0016] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0017] like Figure 1 The diagram shows a schematic of the coil starting and ending wire bending mechanism provided by this utility model. The coil starting and ending wire bending mechanism includes a three-axis moving assembly 10, a wire pulling assembly 20 disposed on one side of the three-axis moving assembly 10, a bending assembly 30 disposed on one side of the wire pulling assembly 20, and a winding assembly 40 disposed on one side of the bending assembly 30. It is conceivable that the coil starting and ending wire bending mechanism also includes other functional modules, such as an assembly module, a power supply module, a drive module, etc., which are technologies known to those skilled in the art and will not be described in detail here.

[0018] Please also refer to Figures 2 to 4 The output end of the three-axis moving component 10 is provided with a support plate 11. The three-axis moving component can drive the support plate 11 to move in a three-dimensional space. In this way, the three-axis moving component 10 can drive the support plate 11 and move the components on the support plate 11, thereby completing the functions of guiding and transferring the wire. The three-axis moving component 10 itself is prior art and will not be described in detail here.

[0019] A guide pin 12 is provided on one side of the support plate 11. The guide pin 12 is used to pass through the wire, thereby guiding the wire. The length direction of the guide pin 12 is parallel to the arrangement direction of the wire pulling assembly 20 and the folding assembly 30, so that the wire passing through the guide pin 12 can be clamped by the wire pulling assembly 20 and the folding assembly 30.

[0020] The wire pulling assembly 20 includes a drive cylinder 21 fixedly mounted on the support plate 11, a wire pulling cylinder 22 mounted on the output end of the drive cylinder 21, and two grippers 23 correspondingly mounted on the output end of the wire pulling cylinder 22.

[0021] The driving cylinder 21 is located on one side of the guide needle 12, and its output direction is perpendicular to the length direction of the guide needle 12. Thus, the driving cylinder 21 can drive the wire pulling cylinder 22 to approach or move away from the wire that has passed through the guide needle 12.

[0022] The wire-pulling cylinder 22 can drive the two grippers 23 to open or close, thereby clamping the wire. One gripper 23 has a toothed gripping surface, allowing it to cooperate with the other gripper 23 to hold the wire. The other gripper 23 has a spring 24 inside, with a clamping block 25 on one side. The clamping block 25 slides through the gripper 23, and one end face of the clamping block 25 is toothed and protrudes from the gripper 23. The toothed surface of the clamping block 25 corresponds to the toothed surface of the gripper 23, thus strengthening the clamping force on the wire and preventing it from loosening. The clamping block 25 is fitted onto a horizontally arranged guide post, thus limiting the clamping block 25 and preventing it from slipping out of the gripper 23.

[0023] One end of the spring 24 abuts against the inner wall of the gripper 23, and the other end abuts against the clamping block 25. When the two grippers 23 approach each other under the drive of the wire pulling cylinder 22, the toothed surface of one gripper 23 abuts against the toothed surface of the clamping block 25 in the other gripper 23, clamping the wire and compressing the spring 24. The clamping force is provided by the elastic potential energy of the spring 24, thereby preventing damage and deformation of the wire.

[0024] The wire-pulling cylinder 22 drives the gripper 23 to hold the wire passing through the guide needle 12, and under the drive of the three-axis moving assembly 10, the wire is transferred to the winding assembly 40 for winding operation.

[0025] The zigzag assembly 30 includes an X-axis cylinder 31 disposed on the support plate 11, a Y-axis cylinder 32 disposed at the output end of the X-axis cylinder 31, a zigzag cylinder 33 disposed at the output end of the Y-axis cylinder 32, and two clamping fingers 34 disposed at the output ends of the zigzag cylinder 33.

[0026] The output direction of the X-axis cylinder 31 is parallel to the output direction of the drive cylinder 21, and the output direction of the Y-axis cylinder 32 is perpendicular to the output direction of the X-axis cylinder 31 and parallel to the length direction of the guide needle 12. Thus, the X and Y axis cylinders 31 and 32 can drive the zigzag cylinder 33 to move in a two-dimensional plane. The zigzag cylinder 33 can drive the two clamping fingers 34 to open or close, thereby clamping the starting wire and moving it under the drive of the X and Y axis cylinders 31 and 32 to perform the wire pulling operation.

[0027] The winding assembly 40 includes a lower die 41, an upper die 42 disposed on one side of the lower die 41, a wire clamp 43 fixedly disposed on one side of the lower die 41, a first stop 44 movably disposed on the lower die 41, and a second stop 45 movably disposed on one side of the first stop 44.

[0028] A protrusion 46 is provided on the lower mold 41. During the winding operation, the wire clamp 43 clamps the starting wire, and the upper and lower molds 42 and 41 close and rotate under the action of a driving device, so that the wire is wound on the circumferential outer wall of the protrusion 46, thereby completing the winding operation.

[0029] The first and second stops 44 and 45 are disposed on one side of the protrusion 46 and are in gap contact with the wound coil. The first stop 44 is located between the wound coil and the starting segment of the coil, and the second stop 45 is located at the end of the starting segment of the wound coil near one end of the coil. The movement direction of the first and second stops 44 and 45 is parallel to the arrangement direction of the upper and lower dies 42 and 41. Each of the first and second stops 44 and 45 is disposed at the output end of a driving device. Thus, under the action of the two driving devices, the first and second stops 44 and 45 can perform lifting and lowering movements. When the wire is being wound, the first and second stops 44 and 45 descend to be flush with the surface of the lower die 41 to avoid interfering with the wire winding operation.

[0030] The following is a detailed explanation of how to perform the bending operation. After the winding operation is completed and the upper and lower dies 42 and 41 are opened, the coil is fitted onto the protrusion 46. The starting wire of the coil is clamped on the wire clamp 43, and the tail wire of the coil passes through the guide pin 12 and is connected to the wire storage cylinder. The first stop block 44 rises, and its side facing the protrusion 46 is pressed tightly against the tail wire of the coil. In this way, the lower die 41 rotates in the opposite direction by a certain angle, so that the tail wire of the coil is bent at a certain angle with the coil, thereby completing the bending operation of the tail wire of the coil. Then the second stop 45 rises. At this time, the second stop 45 is located at the end of the starting line segment of the wound coil near one end of the coil. The clamping finger 34 in the bending assembly 30 moves to the wire clamp 43 under the drive of the X and Y axis cylinders 31 and 32, and clamps the starting line of the coil under the drive of the bending cylinder 33. The X and Y axis cylinders 31 and 32 drive and move the wire clamp 43, so that the starting line segment of the coil is bent at a certain angle with the coil, thereby completing the bending operation of the starting line of the coil.

[0031] Compared with the prior art, the coil starting and ending wire bending mechanism provided by this utility model drives the support plate 11 through the three-axis moving component 11, which in turn drives the wire pulling component 20 and the bending component 30 to move, thereby completing the functions of guiding and transferring the wire. After the coil is wound, the first stop 44 rises, and after the lower mold 41 rotates in the opposite direction by a certain angle, the ending wire segment of the coil will also bend at a certain angle with the coil. Then the second stop 45 rises, and the clamping fingers 34 in the bending component 30 clamp the starting wire of the coil and move under the drive of the X and Y axis cylinders 31 and 32, thereby bending the starting wire segment of the coil at a certain angle with the coil. The coil starting and ending wire bending mechanism can bend the starting and ending wire of the coil at a certain angle without manual operation, saving manpower, improving production efficiency, and is suitable for assembly line production.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
