Description

Technical Field

[0001] The utility model relates to the technical field of winding machines, and more specifically, to a wire feeding device. Background Art

[0002] A winding machine is a device that winds a linear object onto a specific workpiece, usually used for copper wire winding. Most electrical products need to be wound into an inductor coil with enameled copper wire (enameled wire for short), and a winding machine can be used to complete this one or more processes. The wire feeding device used in the existing winding machine has a relatively complex structure. For example, CN202111071099.0 A coil winding method for a winding machine with upper and lower hooks. This patent mentions that the wire feeding module is directly above the winding module and feeds the wire vertically downward, wherein the copper wire needs to be squeezed by multiple wire adjustment and fixing wheels, and is transformed from the original bent state to a relatively straight state, and then passes through the iron core in a direction perpendicular to the iron core. The defect of this structure is that in order to avoid the influence of the wire feeding module on the winding process, an additional moving mechanism needs to be set up to drive the wire feeding module to deviate from the top of the winding module. Obviously, this wire feeding module occupies a large space area, and the overall structure is relatively complex. Therefore, it is necessary to develop a new wire feeding device.

DETAILED DESCRIPTION

[0023] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] It is worth noting that the directional words such as "upper" and "lower" involved in this article are all relative to the viewing angle of the drawings and are only for the convenience of description and cannot be understood as limitations on the technical solution.

[0025] like Figure 1-4The utility model provides a wire feeding device, comprising a substrate 1, a deflection mechanism and a wire feeding mechanism, wherein the wire feeding mechanism is arranged on the substrate 1, and the deflection mechanism is arranged below the substrate 1, and the deflection mechanism controls the substrate 1 to rotate in a horizontal plane, thereby rotating the wire feeding mechanism.

[0026] The wire feeding mechanism includes a wire feeding motor 3, a driving wheel 2, a clamping cylinder 5, a fixed shaft 21, a rotating frame 4, a driven wheel 20, a cutter and a wire feeding tube assembly. The driving wheel 2 is horizontally and rotatably arranged above the base plate 1, the wire feeding motor 3 is arranged below the base plate 1, the transmission shaft of the wire feeding motor 3 is connected to the driving wheel 2 in a transmission manner, the fixed shaft 21 is vertically arranged on the base plate 1, the fixed shaft 21 is rotatably connected to one side of the rotating frame 4, and the driven wheel 20 is horizontally and rotatably arranged on the rotating frame 4, and the driven wheel 20 is close to the driving wheel 2, the copper wire is between the driven wheel 20 and the driving wheel 2, the clamping cylinder 5 is arranged outside the side of the rotating frame 4 away from the driving wheel 2, and the piston rod of the clamping cylinder 5 is close to the other side of the rotating member away from the fixed shaft 21 to drive the rotating frame 4 to move toward the driving wheel 2 to compress the copper wire, the wire feeding tube assembly is arranged in front of the driving wheel 2, and the front end of the wire feeding tube assembly is bent downward toward the iron core, and the cutter is in front of the driving wheel 2 and located on the outside of the copper wire to cut the copper wire.

[0027] The utility model is located on one side of the winding device of the winding machine, and its working principle is: first, the copper wire passes through the driven wheel 20 and the driving wheel 2 and enters the wire feeding tube assembly. When the copper wire needs to be transported, the piston rod of the clamping cylinder 5 extends to push the rotating frame 4 to move in the direction of the driving wheel 2, so that the driven wheel 20 applies pressure in the direction of the driving wheel 2, and the copper wire is tightly clamped between the driven wheel 20 and the driving wheel 2. Then, the wire feeding motor 3 drives the driving wheel 2 to rotate, and the copper wire is transported forward by friction. The length of the transported copper wire can be obtained according to the circumference of the circular cross section of the driving wheel 2 and the number of rotations.

[0028] It is easy to understand that the copper wire is initially straightened after being pressed by the driving wheel 2 and the driven wheel 20. Since the front end of the wire feeding tube assembly is bent toward the iron core, the copper wire will not be curled during the continuous output of the copper wire through the iron core.

[0029] Before conveying the copper wire, the front end of the wire feeding tube assembly is aligned with the middle of the iron core, and the copper wire passes through the middle of the iron core. After the length of the conveyed copper wire reaches the set value, the driving wheel 2 stops rotating, and the driving wheel 2 and the driven wheel 20 still maintain the state of clamping the copper wire. Then the deflection mechanism drives the wire feeding mechanism to deflect an angle as a whole, so that the front end of the wire feeding tube assembly is offset from the iron core, which is convenient for subsequent winding operations. When it is necessary to cut the copper wire, the cutter is started to cut the copper wire, and the copper wire in the front is continued to be wound and used, and the copper wire between the driven wheel 20 and the driving wheel 2 at the rear remains in a compressed state, waiting for the next wire feeding.

[0030] It is easy to understand that the wire feeding motor 3 is provided with a feasible sensor such as an encoder to detect the number of revolutions of the driving wheel 2 .

[0031] Preferably, in order to further improve the straightening effect on the copper wire during the transportation process, the wire feeding tube assembly includes a wire feeding straightening member 6, a wire feeding straight tube 7, a first support column 8 and a wire feeding curved tube 9, such as Figure 1-4 As shown, the wire straightening member 6 is fixedly arranged on the substrate 1 and is located in front of the driving wheel 2. The wire straightening member 6 is provided with a straight-through hole along the wire feeding direction. The cutter is located on one side of the wire straightening member 6, and the wire straightening member 6 is provided with a connecting hole on the side facing the cutter, and the connecting hole leads to the straight-through hole, so that the cutter can cut the copper wire from the side of the copper wire. The wire straight tube 7 is fixedly arranged on the substrate 1 through a plurality of first support columns 8. The wire straight tube 7 is arranged in front of the wire straightening member 6 along the wire feeding direction, and the wire straight tube 7 is aligned with the straight-through hole. The wire bending tube 9 is arranged in front of the wire straight tube 7, and the central angle of the wire bending tube 9 is 90°. One end of the wire bending tube 9 is connected to the end of the wire straight tube 7, and the other end of the wire bending tube 9 faces the iron core, wherein the diameter of the straight-through hole, the inner diameter of the wire straight tube 7 and the inner diameter of the wire bending tube 9 are all equal to the diameter of the copper wire.

[0032] The copper wire raw material is in a coiled form. After one end of the copper wire enters the wire feeding device, it is clamped by the driving wheel 2 and the driven wheel 20. During the wire feeding process, the copper wire is initially straightened and can only move along a straight pipeline. The inner diameter of these pipelines, namely the straight-through hole and the wire feeding straight pipe 7, is the same as the diameter of the copper wire. The copper wire is further straightened during its forward movement, and finally the copper wire enters the wire feeding elbow 9. Since the inner diameter of the wire feeding elbow 9 is the same as the diameter of the copper wire, the copper wire can only move forward along the wire feeding elbow 9, and finally leaves the wire feeding elbow 9 in a direction perpendicular to the iron core.

[0033] The function of the wire feeding bend 9 is to change the direction of the copper wire. Since the copper wire has been straightened before entering the wire feeding bend 9, it will not curl after passing through the wire feeding bend 9.

[0034] Preferably, the wire feeding mechanism also includes an introduction component, which includes an introduction straight pipe 11 and a second support column 12. The introduction straight pipe 11 is located behind the driving wheel 2 and the driven wheel 20, and the introduction straight pipe 11 is aligned with the straight through hole. The introduction straight pipe 11 is fixed on the base plate 1 through the second support column 12.

[0035] It is easy to understand that the introduction straight tube 11, the straight through hole and the wire feeding straight tube 7 are on the same straight line along the wire feeding direction, and the function of the introduction straight tube 11 is to guide the copper wire between the driving wheel 2 and the driven wheel 20.

[0036] More preferably, the wire feeding mechanism further includes a guide wheel 13, which is arranged behind the guide straight tube, and the top surface of the guide wheel 13 is higher than the guide straight tube or flush with the guide straight tube. The function of the guide wheel 13 is to guide the copper wire so that the copper wire can enter the subsequent structure more conveniently.

[0037] Preferably, the wire feeding mechanism further comprises a clamping member 19, the clamping member 19 is arranged in front of the substrate 1, a clamping position is arranged at the front end of the clamping member 19, and the front end of the wire feeding elbow 9 passes through the clamping position and faces downward.

[0038] In the present invention, the structure of the cutter is various. Preferably, the cutter comprises a cutter and a cutter cylinder 10, the cylinder body of the cutter cylinder 10 is fixedly arranged on the base plate 1, the cutter is arranged on the piston rod of the cutter cylinder 10, and the cutter is directed toward the copper wire through the connecting hole.

[0039] When the copper wire needs to be cut, the piston rod of the cutting cylinder 10 extends to drive the cutter to cut the copper wire in the wire feeding straightening member 6. During the wire feeding, the piston rod of the cutting cylinder 10 retracts to close the connecting hole to prevent the cutter from contacting the copper wire. It is easy to understand that when the cutter closes the connecting hole, the straight through hole can be regarded as continuous, and the copper wire will not pass through the connecting hole.

[0040] In the present invention, the deflection mechanism includes a deflection motor 14, a fixing seat 15 and a connecting column 16, wherein the fixing seat 15 is provided with a connecting hole in the vertical direction, the connecting column 16 is provided above the connecting hole, and the connecting column 16 is rotatably connected to the fixing seat 15, the deflection motor 14 is provided below the fixing seat 15, and the transmission shaft of the deflection motor 14 passes through the connecting hole and is connected to the bottom end of the connecting column 16, and the top end of the connecting column 16 is fixedly connected to the bottom surface of the substrate 1. It is easy to understand that the fixing seat 15 is installed on the winding machine, and the deflection motor 14 drives the connecting column 16 to rotate, so as to realize the overall rotation of the wire feeding mechanism.

[0041] Preferably, the deflection mechanism also includes a detection component for detecting whether the connecting column 16 is rotated into place, and the detection component includes one or both of a proximity switch 17 and a partial encoder. The proximity switch 17 is arranged on the fixed seat 15, and a detection piece 18 used in conjunction with the proximity switch 17 is arranged on the side of the connecting column 16. The partial encoder is arranged on the deflection motor 14 and is used to detect the rotation angle of the connecting column 16.

[0042] It should be noted that, in the present invention, "front" and "rear" are used as the Figure 1 Based on the perspective, Figure 1 The left side is the front of the device. Figure 1 The right side is the rear of the device.

[0043] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
