Abstract
Description
A wire feeding mechanism Technical Field
[0001] This utility model relates to the field of winding machine technology, and more specifically, to a wire feeding mechanism. Background Technology
[0002] A winding machine is a device that winds a wire-like object onto a specific workpiece, typically used for winding copper wire. The wire feeding mechanism is a crucial component of the winding machine. When the winding machine winds copper wire onto the workpiece, the wire feeding mechanism generally feeds the wire continuously during the winding process. When the total length of the wire fed matches the required winding length, the wire feeding mechanism cuts the copper wire. The remaining copper wire is then pulled forward by the winding mechanism until the winding is complete. After the copper wire is cut, the remaining length within the wire feeding mechanism is related to a fixed distance between the cutting point of the wire feeding mechanism and the copper wire exit point; that is, for the wire feeding mechanism, the shortest possible wire feeding length is the fixed distance within the wire feeding mechanism itself. Existing winding equipment, based on the design of the winding mechanism, struggles to address the problem of excessively long remaining copper wire. This results in the winding machine being unsuitable for situations with a small number of winding turns, and the excessively long remaining copper wire causes the winding mechanism to malfunction, necessitating the replacement with another winding machine, which is extremely inconvenient. Therefore, this utility model proposes a new wire feeding mechanism to solve the above problems. Summary of the Invention

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0024] It is worth noting that the directional terms such as "up" and "down" used in this article are all relative to the perspective of the attached figures and are only for the purpose of description. They should not be interpreted as limitations on the technical solutions.
[0025] This utility model proposes a wire feeding mechanism that has the function of shortening the remaining copper wire length.
[0026] As shown in Figures 1-3, the wire feeding mechanism includes a base plate 1, a wire supply assembly 4, a cutting assembly 3, and a wire assembly 2. The base plate 1 includes an integrally formed first mounting plate 11, a second mounting plate 12, and a side mounting plate 14. The second mounting plate 12 is located in front of the first mounting plate 11. The wire supply assembly 4 is disposed on the first mounting plate 11, the wire assembly 2 is disposed on the second mounting plate 12, the side mounting plate 14 is disposed on one side of the second mounting plate 12, and the cutting assembly 3 is disposed on the side mounting plate 14, located between the wire assembly 2 and the wire supply assembly 4. The distance between the cutting point of the cutting assembly 3 and the wire outlet of the wire assembly 2 is 30-50 mm.
[0027] This invention moves the position of the cutting component 3 forward, shortening the distance between the cutting point and the copper wire outlet. The shortest wire feeding length is 30-50 mm, which is suitable for winding inductor coils with few turns. This is easy to understand. This invention is still applicable to products with many turns.
[0028] Furthermore, the conductor assembly 2 includes a straight conductor tube 21, a first support column 23, and a conductor bend 22, as shown in Figure 1. Along the direction of copper wire movement, one end of the straight conductor tube 21 is connected to one end of the conductor bend 22, and the other end of the straight conductor tube 21 is aligned with the copper wire outlet of the cutting assembly 3. The other end of the conductor bend 22 faces downward and serves as the outlet of the conductor assembly 2. The straight conductor tube 21 and the conductor bend 22 are respectively fixed to the second mounting plate 12 by the first support column 23.
[0029] Furthermore, the conductor assembly 2 also includes an auxiliary plate 24, which is positioned in front of the second mounting plate 12. The auxiliary plate 24 has a clamping position 25, through which one end of the conductor bend 22 passes downward. It is easy to understand that the auxiliary plate 24 serves a positioning function, preventing the conductor bend 22 from deflecting.
[0030] The cutting component 3 of this utility model can have various structures, as long as it achieves the effect of cutting copper wire. Specifically, this utility model proposes a cutting component 3, including a wire-cutting cylinder 31, a connecting member 32, and a transition straight tube 33, as shown in Figures 1 and 3. The cylinder body of the wire-cutting cylinder 31 is mounted on the side mounting plate 14. The connecting member 32 is connected to the piston of the wire-cutting cylinder 31. The transition straight tube 33 passes laterally through the connecting member 32 and is positioned between the wire straight tube 21 and the wire supply component 4. The transition straight tube 33 is aligned with the wire straight tube 21, with one end face of the transition straight tube 33 contacting one end face of the wire straight tube 21, and a gap existing between the other end face of the transition straight tube 33 and the wire supply component 4.
[0031] After the wire supply assembly 4 feeds the copper wire into the transition straight tube 33, the copper wire continues to move forward along the transition straight tube 33 and enters the conductor straight tube 21. The working principle of the cutting component 3 is as follows: During normal wire feeding, the piston of the cutting cylinder 31 retracts, connecting the transition straight tube 33 with the conductor straight tube 21. The copper wire passes smoothly through the transition straight tube 33 and the conductor straight tube 21. When it is necessary to cut the copper wire, the wire feeding component 4 stops feeding, and the piston of the cutting cylinder 31 extends. At this time, the transition straight tube 33 and the conductor straight tube 21 are completely misaligned, and the two tubes are no longer connected. The copper wire between the transition straight tube 33 and the conductor straight tube 21 is cut off due to the misalignment of the two tubes. The copper wire in the transition straight tube 33 is still connected to the copper wire in the wire feeding component 4. The end face of the copper wire in the transition straight tube 33 is flush with the end face of the transition straight tube 33. The copper wire in the conductor straight tube 21 continues to advance in cooperation with the winding mechanism. That is, the total length after the conductor straight tube 21 and the conductor bend tube 22 are connected is the shortest wire feeding length of this utility model, which is 30-50 mm. It is easy to understand that the inner diameter of the straight conductor tube 21 and the inner diameter of the transition straight tube 33 are preferably the same. When the piston of the wire-cutting cylinder 31 retracts and returns to its original position, the transition straight tube 33 and the straight conductor tube 21 will be aligned again. Since one end face of the transition straight tube 33 is in contact with one end face of the straight conductor tube 21, the copper wire inside the transition straight tube 33 can still normally enter the straight conductor tube 21. It is also easy to understand that since there is a gap between the transition straight tube 33 and the wire supply assembly 4, when the transition straight tube 33 is displaced, the copper wire between the transition straight tube 33 and the wire supply assembly 4 also has room for displacement and will not be cut off.
[0032] Furthermore, a displacement sensor is installed on the cylinder body of the wire break cylinder 31 to detect the distance of the extension and retraction of the connector 32, ensuring that the transition straight pipe 33 moves into place.
[0033] The wire supply component 4 of this utility model can have various structures, as long as the structure can achieve the effect of conveying copper wire. This utility model proposes a wire feeding assembly 4, including a wire feeding motor 42, a wire feeding cylinder 47, a driving wheel 41, a driven wheel 44, and a deflection bracket 43, as shown in Figure 1. The wire feeding motor 42 is disposed on the bottom surface of the first mounting plate 11, the driving wheel 41 is disposed on the top surface of the first mounting plate 11, the drive shaft of the wire feeding motor 42 passes through the first mounting plate 11 and is connected to the driving wheel 41, the deflection bracket 43 is located on one side of the driving wheel 41, one side of the deflection bracket 43 is rotatably connected to the first mounting plate 11, the driven wheel 44 is located inside the deflection bracket 43, and the driven wheel 44 is rotatably connected to the deflection bracket 43, forming a wire feeding area between the driven wheel 44 and the driving wheel 41, the wire feeding cylinder 47 is disposed on the side of the deflection bracket 43 away from the driving wheel 41, the piston of the wire feeding cylinder 47 is connected to the deflection bracket 43, and controls the driven wheel 44 to move closer to or away from the driving wheel 41.
[0034] The working principle of the wire feeding assembly 4 is as follows: the copper wire passes through the wire feeding area between the driving wheel 41 and the driven wheel 44, the wire feeding cylinder 47 drives the deflection bracket 43 to rotate, so that the driven wheel 44 approaches the driving wheel 41 and presses the copper wire tightly, and then the wire feeding motor 42 drives the driving wheel 41 to rotate, thereby realizing wire feeding.
[0035] Furthermore, an encoder is installed on the wire feeding motor 42 to record the number of rotations of the drive wheel 41, thereby calculating the wire feeding length.
[0036] Furthermore, the wire supply assembly 4 also includes a wire feeding tube 45 and a second support column 46. One end of the wire feeding tube 45 faces the wire feeding area between the driving wheel 41 and the driven wheel 44, and the other end of the wire feeding tube 45 is aligned with one end of the transition tube 33, with a gap between the wire feeding tube 45 and the transition tube 33. The wire feeding tube 45 is fixedly mounted on the first mounting plate 11 by the second support column 46. The gap between the wire feeding tube 45 and the transition tube 33 can prevent the copper wire between the wire feeding tube 45 and the transition tube 33 from breaking when the transition tube 33 moves.
[0037] Furthermore, a connecting post 13 is provided on the bottom surface of the first mounting plate 11 to facilitate installation on the winding machine.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
