Technical Field

[0001] The present invention relates to the technical field of filamentous material conveying, and particularly relates to a wire feeding device. Background Art

[0002] Enameled wire is an important variety of winding wire and is commonly used in electrical products such as motors and transformers.

[0003] During the winding process of enameled wire, the feeding amount of the wire often falls within a suitable range due to the increase of the wire on the reel or the rotational speed deviation of the reel. The floating and deviation of this feeding amount will cause the enameled wire to be loose or twisted after winding, which will have a certain impact on the safety and service life of electronic products. Summary of the Invention

[0012] Preferably, the second part is flat and plate-shaped and is horizontally arranged.

[0013] Preferably, the induction unit includes a first induction member and a second induction member. The first induction member is arranged on the mounting assembly, and the second induction member is arranged on the connecting member or the counterweight member and is adapted to receive the signal of the first induction member.

[0014] Preferably, the induction unit includes a first induction member and a second induction member.

[0015] Preferably, the mounting assembly includes: a support base on which a U-shaped space is provided; the floating assembly and the induction unit are both arranged in the U-shaped space; a transmission mechanism and a roller connected to the transmission mechanism. The transmission mechanism is arranged on the support base, the wire coil is arranged on the roller and is located directly above the U-shaped space; the transmission mechanism is adapted to drive the roller to rotate to drive the wire coil to rotate.

[0016] The technical solution of the present invention has the following advantages:

[0017] 1. For the wire feeding device of the present invention, a roller-type wire coil is arranged on the mounting assembly and rotates under the drive of the roller-type mounting assembly. A cable is arranged on the roller-type wire coil; the floating assembly is slidably arranged on the roller-type cable and floats up and down under the drive of the roller-type cable; the control assembly is used to control the action of the roller-type mounting assembly, and an induction unit is arranged thereon.

[0018] During use, the wire coil is arranged on the mounting assembly, the floating assembly is arranged on the cable, the control assembly is turned on. Due to the gravity factor of the floating assembly itself, it slides to a position of the cable close to the induction unit; the mounting assembly drives the wire coil to rotate for wire feeding, and the floating assembly descends along with the cable. Since the induction unit is arranged at the set height, when the floating assembly descends to the set height, the induction unit is triggered.

[0019] Through the up and down floating of the floating assembly, the induction unit can sense in real time whether the wire feeding amount of the cable is within a reasonable range, thereby eliminating the problems that the enameled wire may become loose or twisted after winding due to the floating and deviation of the tension, and improving the safety and service life of electronic products.

[0028] The following will clearly and completely describe the technical solutions of the present invention with reference to the drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present invention belong to the scope of protection of the present invention.

[0029] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] The wire feeding device of this embodiment, as Figures 1-3 shown, includes: an installation component, a wire reel 1, a floating component, and a control component.

[0033] Among them, the roller-type wire reel 1 is vertically arranged on the installation component and rotates under the drive of the roller-type installation component. Compared with the current market method of horizontally placing the wire reel, the method of vertically arranging the roller-type wire reel 1 greatly reduces the floor area, shortens the wire feeding distance, and improves the utilization rate of the wire and cable.

[0034] A wire and cable 2 is provided on the roller-type wire reel 1; the floating component is slidably arranged on the roller-type wire and cable 2 and floats up and down under the drive of the roller-type wire and cable 2; the control component is used to control the action of the roller-type installation component, and an induction unit is provided thereon. The roller-type induction unit is arranged at a set height and is used to sense the position of the roller-type floating component. It should be noted that the set height can be set according to the actual wire feeding amount required. In addition, the wire and cable 2 in this embodiment is an enameled wire.

[0035] During use, the wire reel 1 is arranged on the installation component, the floating component is arranged on the wire and cable 2, and the control component is turned on. Due to the gravity factor of the floating component itself, it slides to the position of the wire and cable 2 close to the induction unit; the installation component drives the wire reel 1 to rotate for wire feeding, and the floating component descends with the wire and cable 2. Since the induction unit is arranged at the set height, when the floating component descends to the set height, the induction unit is triggered. At this time, the control component controls the installation component to reduce the rotation speed of the wire reel 1 or stop rotating; at this time, the floating component ascends with the wire and cable 2, and the induction unit receives the signal again, and the control unit drives the wire reel 1 to increase the rotation speed.

[0036] Through the up and down floating of the floating component, the induction unit can sense in real time whether the wire feeding amount of the wire and cable 2 is within a reasonable range, thereby eliminating the problems that the enameled wire may become loose or twisted after winding due to the floating and deviation of the tension, and improving the safety and service life of electronic products.

[0037] Among them, the floating component includes: a connecting member 3, a groove 4 is provided on the connecting member 3, and the cable 2 is arranged at the groove 4 and is slidably connected to the groove 4; specifically, the connecting member 3 is in the shape of a roller, and the groove 4 is annular and coaxially arranged with the center of the connecting member 3.

[0038] As a transformable implementation manner, the groove 4 can be only arranged below the connecting member 3, and its trajectory is arc-shaped.

[0039] Specifically, three connecting members 3 are arranged on the wire feeding device of this embodiment. The three connecting members 3 are evenly distributed on the cable 2 and are in an inverted triangular shape, and the central connection lines thereof form an isosceles triangle.

[0040] Furthermore, the floating component further includes: a counterweight 6, which is connected to the connecting member 3. The counterweight 6 is connected to the connecting member 3. Among them, the counterweight 6 includes: a first part 7 and a second part 8. The first part 7 is connected to the connecting member 3; the second part 8 is connected to the first part 7 and is arranged below the groove 4 to limit the cable 2 in the groove 4.

[0041] By setting the counterweight 6, the bending degree of the cable 2 is reduced, and it is avoided that the wire feeding amount of the cable 2 exceeds the appropriate range; by setting the second part 8, it is prevented that the floating component disengages from the groove 4 during the up and down floating process.

[0042] Furthermore, the counterweight 6 further includes: a third part 9, which is connected to the second part 8 and is provided with a connection hole for connecting a counterweight block; during use, the weight of the counterweight 6 can be increased or decreased according to actual needs; the first part 7 is connected to the first side surface of the connecting member 3, the third part 9 is arranged below the connecting member 3, the first part 7, the second part 8 and the third part 9 are arranged in a stepped shape, and the first part 7 and the third part 9 are inclined towards the second part 8. The purpose of adopting this inclined setting method is to prevent the connecting member 3 from tilting and prevent the cable 2 from disengaging from the groove 4 during the floating process.

[0043] The second part 8 is a flat plate shape and is arranged horizontally. As a transformable implementation manner, the second part 8 is arc-shaped and is arranged on the outer periphery of the connecting member 3.

[0044] The sensing unit includes a first sensing member 10 and a second sensing member 11. The first sensing member 10 and the second sensing member 11 are both arranged on the mounting component. The floating component blocks the communication connection between the first sensing member 10 and the second sensing member 11, and the first sensing member 10 and the second sensing member 11 are grating sensors.

[0045] As a transformable embodiment, the sensing unit includes a first sensing member 10 and a second sensing member 11. The first sensing member 10 is disposed on the mounting assembly, and the second sensing member 11 is disposed on the counterweight member 6 and is adapted to receive the signal of the first sensing member 10. As a transformable embodiment, the second sensing member 11 can also be disposed on the connecting member 3. In this embodiment, the first sensing member 10 and the second sensing member 11 are photoelectric sensors.

[0046] Among them, the mounting assembly includes: a support base 12, on which a U-shaped space 5 is provided, and both the floating assembly and the sensing unit are disposed in the U-shaped space 5; a transmission mechanism and a roller 13 connected to the transmission mechanism. The transmission mechanism is disposed on the support base 12, and the wire reel 1 is disposed on the two rollers 13 and is located directly above the U-shaped space 5. The transmission mechanism drives the roller 13 to rotate, and the roller 13 drives the wire reel 1 to rotate under the action of friction.

[0047] Among them, the transmission mechanism includes a motor, a pulley 14 and a belt. The motor drives the pulley 14 to rotate, and further drives the roller 13 to act.
