Description

Technical Field

[0001] This utility model relates to the field of coil production equipment technology, and in particular to a coil stranding mechanism. Background Technology

[0002] After the coil is wound, the next processing step is to put the wound coil into the corresponding shell and align the copper wires with the pins of the shell. However, the freshly wound coils are of different lengths and the wires are intertwined and messy, so they cannot be put directly into the shell. At the same time, some copper wires have two wires corresponding to the same pin, so the two copper wires need to be twisted into one. Therefore, it is particularly critical and important to separate and twist multiple sets of copper wires in advance.

[0003] Traditional coil winding processes are performed manually, resulting in low production efficiency and lower product quality, thus reducing the yield of high-quality products. CN 221175970 U discloses a stranding mechanism for inductors that can automatically complete the stranding process. Although this stranding mechanism includes a vertical displacement cylinder, the main function of the cylinder is to position the inductor, not to adjust the height of the stranding clamp. In other words, the stranding clamp is fixed in the height direction, which reduces the flexibility of the stranding mechanism. Utility Model Content

[0004] Therefore, it is necessary to provide a coil stranding mechanism to address the problem that existing stranding mechanisms cannot be height adjusted, thus reducing the flexibility of their use.

[0005] A coil stranding mechanism, comprising:

[0006] Lift drive;

[0007] A horizontal drive, which is connected in a transmission manner to the lifting drive;

[0008] Mounting plate, which is connected to the horizontal driver in a driving connection;

[0009] A stranded wire clamp assembly, the stranded wire clamp assembly being rotatably mounted on the mounting plate; and

[0010] A rotary driver is fixedly mounted on the mounting plate, and the stranded wire clamp assembly is connected to the rotary driver for transmission.

[0011] The aforementioned coil stranding mechanism can adjust the height of the stranding clamp assembly via a lifting driver, making it easier to use with a wire separating mechanism and adapting to more types of coil stranding, thus effectively expanding its application range. During the stranding process, the horizontal driver drives the stranding clamp assembly to move horizontally, which avoids the copper wire from being easily pulled apart during stranding, thereby effectively improving production quality and increasing the yield of high-quality products.

The driving member is provided with a pushing inclined surface, and the stranding clamp is provided with a pushing surface adapted to the pushing inclined surface. The piston rod of the opening cylinder pushes the push rod out, and the driving member moves accordingly. The pushing inclined surface cooperates with the pushing surface to open the stranding clamp.

[0018] In one embodiment, the coil stranding mechanism further includes a transmission assembly, which includes a drive wheel, a transmission wheel, and a timing belt. The drive wheel is connected to the rotary driver, the transmission wheel is fitted onto the rotating sleeve, and the transmission wheel is synchronously connected to the drive wheel via the timing belt.

[0041] Please see Figure 1 The coil stranding mechanism 100 of this utility model includes a lifting driver 10, a horizontal driver 20, a mounting plate 30, a stranding clamp assembly 40, and a rotary driver 50. The horizontal driver 20 is drivenly connected to the lifting driver 10, the mounting plate 30 is drivenly connected to the horizontal driver 20, the stranding clamp assembly 40 is rotatably disposed on the mounting plate 30, the rotary driver 50 is fixedly disposed on the mounting plate 30, and the stranding clamp assembly 40 is drivenly connected to the rotary driver 50.

[0042] Please see Figure 1 and Figure 2The movement direction of the lifting driver 10 is perpendicular to the movement direction of the horizontal driver 20. The stranded wire clamp assembly 40 includes a base 41, a rotating sleeve 42, a bearing 43, a stranded wire clamp 44, and a hinge shaft 47. The base 41 is fixedly mounted on the mounting plate 30, and the rotating sleeve 42 is rotatably connected to the base 41 through the bearing 43. The rotating sleeve 42 includes a sleeve portion 421 and an extension portion 422 connecting the sleeve portion 421. There are two extension portions 422, which are correspondingly arranged between each other. Each extension portion 422 has a hinge hole. The stranded wire clamp 44 includes a stranded wire clamp 44 block and a torsion spring. Each stranded wire clamp 44 block has a through hole. There are two stranded wire clamps 44 blocks, which are respectively arranged on both sides of the extension portion 422. The through holes of the two stranded wire clamps 44 blocks overlap. The hinge shaft 47 passes through the through hole and engages with the hinge hole, allowing the two stranded wire clamps 44 blocks to open and close relative to each other between the two extension portions 422. A silicone pad is fixedly provided on the inner side of each stranded wire clamp 44 block. The silicone pad prevents the copper wire from being damaged during clamping and also improves the stability of the copper wire clamping, effectively improving the working stability of the coil stranding mechanism 100. The torsion spring is fitted outside the hinge shaft 47. One torsion arm of the torsion spring abuts against one of the stranded wire clamps 44, and the other torsion arm of the torsion spring abuts against the other stranded wire clamp 44.

[0043] Please see Figures 1 to 3 The stranded wire clamp assembly 40 further includes a push rod 45, a driving member (not shown), and an elastic member 46. The sleeve portion 421 is provided with a through groove in the axial direction. The push rod 45 includes a rod portion 451 and a limiting portion 452 connecting the rod portion 451. The rod portion 451 passes through the through groove and is fixedly connected to the driving member. The end of the driving member away from the rod portion 451 is provided with a pushing inclined surface. The stranded wire clamp 44 is provided with a pushing surface 441 adapted to the pushing inclined surface. The elastic member 46 is fitted outside the rod portion 451. One end of the elastic member 46 abuts against the rotating sleeve 42, and the other end of the elastic member 46 abuts against the limiting portion 452.

[0044] Please see Figures 1 to 3 The coil stranding mechanism 100 also includes an opening clamp cylinder, which is fixedly connected to the mounting plate 30. When the piston rod of the opening clamp cylinder pushes out and pushes the push rod 45, the driving member pushes forward and cooperates with the pushing surface on the pushing slope to drive the stranding clamp 44 to open.

[0045] Please see Figure 1 and Figure 2, the coil stranding mechanism 100 further includes a transmission component 70. The transmission component 70 includes a driving wheel 71, a driven wheel 72 and a synchronous belt 73. The driving wheel 71 is in transmission connection with the rotary driver 50.

[0046] Please refer to Figure 1 and Figure 2 , the coil stranding mechanism 100 further includes a photoelectric switch 80 for measuring the number of rotation turns of the stranding clamp component 40 and an induction sleeve 90 used in cooperation with the photoelectric switch 80. The induction sleeve 90 is fixedly sleeved outside the rotary sleeve 42. The induction sleeve 90 is provided with an induction plate 91. The photoelectric switch 80 is fixedly arranged on the base 41. The rotation of the rotary sleeve 42 drives the induction sleeve 90 to rotate. The induction plate 91 passes between the two induction heads on the photoelectric switch 80 to achieve the detection function.

[0047] The working principle of the coil stranding mechanism 100 in this embodiment: During stranding, the piston rod of the clamp opening driver 60 pushes outwards against the push rod 45. The push rod 45 extends between the two stranding clamp blocks 44 to drive the stranding clamp 44 to open. The manipulator cooperating with the coil stranding mechanism 100 places the copper wire to be stranded between the two stranding clamp blocks 44. The clamp opening driver 60 resets. Under the action of the elastic member 46, the push rod 45 resets. The two stranding clamp blocks 44 close under the action of the spring to clamp the copper wire to be stranded. The rotary driver 50 drives the stranding clamp 44 to rotate to achieve the stranding process. During the stranding process, the horizontal driver 20 drives the stranding clamp 44 to move horizontally. In this way, it can avoid the phenomenon that the copper wire is easily broken during stranding, thereby effectively improving the production quality and the excellent product rate. At the same time, the height of the stranding clamp 44 can be adjusted by the lifting driver 10, so as to be more convenient to be used in cooperation with the wire dividing mechanism, adapt to the coil stranding work of more models, and effectively expand the applicable range.

[0048] The technical features of the above embodiments can be combined arbitrarily. For the sake of brief description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0049] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
