Abstract
Description
Technical Field
[0001] The utility model relates to the field of wire management for messy wire harnesses, especially a wire twisting mechanism. Background Art
[0002] A complete copper wire is formed by wrapping a layer of tape or insulating layer around a bundle of copper wires.
[0003] After purchasing these copper wires externally, it is found that the wrapping layer on the copper wires is not completely covered. For example, the copper wires at the head and tail ends of the copper wire are exposed. In addition, due to various collisions during transportation, these exposed copper wires are scattered. The scattered problem will cause the copper wire to get stuck in the guide pin with a relatively small aperture when passing through the guide pin. The conventional method is to manually re-organize the copper wires in this part. In the current fields of electronics and new energy, there is a huge demand for a series of components such as transformers. The manual re-organization method obviously cannot meet the needs of the production line, and the problem of low efficiency will lead to the stagnation of the production line and the reduction of production efficiency. Summary of the Utility Model
[0004] To solve the above problems, the utility model provides a wire twisting mechanism to replace manual re-organization of copper wires and improve the wire twisting efficiency.
[0005] To achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A wire twisting mechanism, characterized in that it has a guiding part, a wire twisting head with a tapered groove inside, and a driving mechanism for driving the rotation of the wire twisting head. The guiding part guides the copper wire into the tapered groove body, and the copper wires on the copper wire gather towards the center point of the tapered groove body along the inner surface of the tapered groove body. By rotating the wire twisting head, the copper wires are wound around each other.
[0007] Further, the tapered groove body is formed by the butting of notches provided on multiple wire twisting blocks. After the wire twisting blocks are expanded, the intertwined copper wires are exposed.
[0008] Further, it also includes a linear movement device. The guiding part includes a fixed guide pin, and the guide pin is located in the tapered groove body. The linear movement device drives the wire twisting head and the driving mechanism to perform linear movement. By squeezing the guide pin against the tapered groove body, the tapered groove body is expanded by the guide pin.
[0009] Further, the stranding head further includes a stranding shaft, a driven wheel, and a spring. Both the stranding shaft and the driven wheel are annular structures. The stranding shaft passes through the inner ring area of the driven wheel with its central axis coinciding with the central axis of the driven wheel. The spring is arranged on the inner side of the driven wheel. An opening adapted to the stranding block is provided on the side surface of the stranding shaft. The stranding block is arranged on the inner ring surface of the driven wheel and compresses the above-mentioned spring. Under the action of the spring, the stranding block maintains a state of passing through the opening and penetrating into the stranding shaft. Moreover, for the stranding blocks inside the stranding shaft, the surfaces in contact with each other are provided with notches, and the abutment between the notches constitutes a tapered groove body. The guide pin penetrates into the stranding shaft to guide the copper wire to contact the inner surface of the above-mentioned tapered groove body.
[0010] Further, the guiding part includes a wire-passing mounting plate, and a first air cylinder, a swing arm, and multiple groups of wire-passing wheels are arranged on the same side of the wire-passing mounting plate. The wire-passing wheels in each group are in contact with each other. The copper wire abuts between each group of wire-passing wheels, and the transportation of the copper wire is guided by the wire-passing wheels. One end of the swing arm is connected to any one of the wire-passing wheels in each group, and the other end of the swing arm is connected to the piston rod of the first air cylinder. The swing arm is rotatably connected to the wire-passing mounting plate, and the first air cylinder drives the swing arm to rotate so that the two wire-passing wheels in the same group are separated.
[0011] Further, a buffer is provided on the piston rod of the first air cylinder, and the buffer abuts against the end of the swing arm.
[0012] Advantages of the present utility model:
[0013] The stranding head in the present utility model is a rotatable component. In this component, there is a tapered groove body. Under the guidance of the tapered groove body, the copper wires gather towards the center of the tapered groove body. Under this gathering, there is a certain compactness between the copper wires and between the copper wires and the tapered groove body. When the stranding head rotates, the copper wires are intertwined with each other to form a twist shape. In this way, it replaces the traditional manual method of arranging copper wires and solves the problem of low production efficiency. Description of the drawings

[0025] The present utility model is applied to the winding equipment in the new energy field, mainly winding copper wires on a skeleton to form a winding.
[0026] Such as Figure 1 shown, the present utility model is a stranding mechanism for re-organizing the scattered copper wires on the copper wire to ensure that the copper wires can smoothly enter other components in the winding equipment.
[0027] The stranding mechanism includes a guiding part and a stranding part. The guiding part is used to guide the copper wire to ensure that the copper wire can smoothly enter the stranding part.
[0028] The guiding part includes a wire-passing mounting plate 10. There are multiple wire-passing wheels on the same side of the wire-passing mounting plate 10, and they are arranged in multiple groups in the form of two wire-passing wheels contacting each other pairwise. The copper wire is located between each group of wire-passing wheels, and the copper wire is guided into the stranding part by means of the wire-passing wheels.
[0029] In each group of wire-passing wheels, the first wire-passing wheel 11 is movable, and this movement can be achieved by moving away from the second wire-passing wheel 12 in the same group, for obtaining a space to place the copper wire between the two wire-passing wheels;
[0030] The second wire-passing wheel 12 is arranged on the wire-passing mounting plate 10 through a rotating shaft, the first wire-passing wheel 11 is arranged on the wire-passing mounting plate 10 through a swing arm 13, and the swing arm 13 is assembled to the wire-passing mounting plate 10 through a rotating shaft, and can drive the first wire-passing wheel 11 to move on the wire-passing mounting plate 10 in a rotational form;
[0031] The wire-passing mounting plate 10 is also provided with a first cylinder 14 for rotating the swing arm 13. Specifically, the output end of the first cylinder 14 faces the first end of the swing arm 13. Under the linear movement of the output end of the first cylinder 14, it can contact and push the swing arm 13 to rotate.
[0032] In the embodiment, the output end of the first cylinder 14 is a piston rod provided with a buffer block 15. Under the action of the piston rod, the buffer block 15 pushes the swing arm 13 to rotate. (As Figure 10 shown)
[0033] This buffer block 15 is made of existing buffer materials, and the types involved include but are not limited to plastics, etc.
[0034] According to the above means of opening the first wire-passing wheel 11 and the second wire-passing wheel 12, this active opening and closing method can be obtained. After the first cylinder 14 stops applying force to the swing arm 13, based on the gravity of the first wire-passing wheel 11 itself, the swing arm 13 is guided to rotate in the opposite direction, thus forming a situation where the copper wire is pressed between the first wire-passing wheel 11 and the second wire-passing wheel 12.
[0035] From the above technical solution, its advantage is that it reduces the energy loss required during operation. That is to say, when guiding the copper wire, using gravity as the power source can press the copper wire against the second wire-passing wheel 12.
[0036] In this embodiment, it also includes an anti-jumping wire device 16, which is also used to guide the copper wire to the space between the first wire-passing wheel 11 and the second wire-passing wheel 12, and the guide pin 17 on the wire-passing mounting plate 10.
[0037] Since the anti-jumping wire device 16 is a prior art, its structure will not be further described herein.
[0038] On the wire-passing mounting plate 10, there are also a plurality of guide pins 17 for guiding the movement of the copper wire. The guide pin 17 at the end of the copper wire movement path penetrates into the stranding part, and the copper wire passes through the guide pin 17 and enters the stranding part.
[0039] The stranding part includes a stranding head 2 and a motor mounting plate 3 (as Figures 2-3As shown in the figure, a linear moving device includes a sliding component 41 and a second cylinder 42. The fixed end of the second cylinder 42 and the sliding component 41 is located on the wire-passing mounting plate 10. The motor mounting plate 3 is fixed to the sliding end of the sliding component 41, and the sliding end is connected to the piston rod of the second cylinder 42 for adjusting the longitudinal height of the motor mounting plate 3. For the wire twisting head 2 provided on the motor mounting plate 3, the adjustment of the longitudinal position is used to push open the wire twisting block 21 that winds the copper wires in the wire twisting head 2, and a wire passing outlet is opened in the wire twisting space, facilitating the extraction of the copper wire from the wire twisting head 2.
[0040] It should be noted that the present utility model is a double-station wire twisting mechanism, and the structure of the other set of linear moving device is as follows:
[0041] The fixed end of the sliding component 41a and the second cylinder 42a are fixed on the wire-passing mounting plate 10. The piston rod of the second cylinder 42a and the moving end of the sliding component 41a are connected to the motor mounting plate 3, and the second cylinder 42a pushes the motor mounting plate 3 to move longitudinally.
[0042] Principle of realizing wire twisting:
[0043] As Figure 4 shown, on the opposite sides of a set of wire twisting blocks 21, there are notches 21a. When realizing pre-twisting, the wire twisting blocks 21 are spliced with each other, and the splicing between the two notches 21a forms a tapered groove body. There are a large number of copper wires. Generally, a copper wire is composed of 50 - 60 copper wires. The scattered copper wires gather towards the center of the tapered groove body under the constraint of the inclined surfaces of the two notches 21a. At this time, there is a certain compactness between the copper wires and between the copper wires and the surface of the tapered groove body. When the wire twisting blocks 21 rotate, the copper wires will be guided by the surface of the tapered groove body to rotate, and this rotation will cause the copper wires to wind around each other and form a twisted shape that can be passed into other components.
[0044] As Figures 5-9 shown, specifically, the wire twisting head 2 further includes a driven wheel 22, a spring (not shown in the figure), and a wire twisting shaft 23:
[0045] The driven wheel 22 is coaxially connected to the bearing 24 carried by the motor mounting plate 3. The stranded wire shaft 23 and the driven wheel 22 are both annular structures. The guide pin 17 penetrates into the stranded wire shaft 23. The stranded wire shaft 23 passes through the inner ring area of the driven wheel 22 in a manner that its central axis Y coincides with the central axis X of the driven wheel 22. The inner ring surface of the driven wheel 22 is provided with a mounting groove 22a. The stranded wire shaft 23 is located on a partial outer periphery of the inner ring area and is provided with an opening 23a. The spring is arranged in the mounting groove 22a of the driven wheel 22 and is maintained in a relative position relationship with the opening 23a. The stranded wire block 21 is also arranged in the mounting groove 22a and corresponds to the opening 23a. Under the action of the spring, the stranded wire block 21 is pushed into the interior of the stranded wire shaft 23 so that the two stranded wire blocks 21 are in contact with each other.
[0046] It also includes a driving mechanism for driving the driven wheel 22 to rotate, the driving mechanism is connected to the motor mounting plate 3, the driving mechanism is a driving motor 5 and a belt 6, the belt 6 is sleeved on the driven wheel 22 and the driving wheel 25 on the driving motor 5.
[0047] The operating principle of the utility model is as follows:
[0048] S1, feeding the copper wire into the guide pin 17 on the wire-passing mounting plate 10;
[0049] S2, open the space between the first wire wheel 11 and the second wire wheel 12, pull the copper wire to the space between the first wire wheel 11 and the second wire wheel 12, release the air pressure in the first cylinder 14, and the swing arm 13 moves toward the second wire wheel 12 under the natural gravity of the first wire wheel 11, and finally the copper wire is pressed against the first wire wheel 11;
[0050] S3, the copper wire passing through the first wire wheel 11 and the second wire wheel 12 enters the conical trough body, and the copper wire is constrained by the conical trough body and gathers at the center of the conical trough body;
[0051] S4, under the action of the driving motor 5, the driven wheel 22 is driven to rotate. The design of the installation groove 22a and the opening 23a allows the stranding shaft 23 and the stranding block 21 to rotate together. The conical groove body formed by the notch 21a pulls the copper wire to entangle with each other and finally form a twist shape, and finally can smoothly enter other components in the winding equipment. (such as Figure 11 shown)
[0052] After the copper wire is wound, the utility model can convey the copper wire continuously by keeping the conical trough body in the state of being stretched out.
[0053] The above embodiments are only descriptions of the preferred embodiments of the present utility model, and do not limit the scope of the present utility model.
