Description

Technical Field

[0001] This utility model relates to the field of transformer production equipment technology, and in particular to a transformer winding machine with infrared positioning and cutting. Background Technology

[0002] In transformer manufacturing, winding formation is one of the key processes. As power equipment develops towards higher efficiency, energy saving, and miniaturization, the requirements for winding structure and manufacturing precision are also increasing. Currently, semi-automatic transformer winding machines are widely used in the production of small and medium-sized transformers, especially for winding flat conductor materials such as aluminum foil and copper foil.

[0003] Existing semi-automatic transformer winding machines typically include a feeding device, a guiding mechanism, a rotating winding shaft, and a drive control system, enabling continuous feeding and fixed-length winding of flat materials. Operators can make auxiliary adjustments during the winding process, thus balancing flexibility and efficiency to a certain extent. This type of equipment is relatively mature in practical applications and is widely used in the production lines of various dry-type transformers, reactors, and special transformers.

[0004] However, after winding flat materials such as aluminum foil using a semi-automatic transformer winding machine, manual cutting is usually required to cut the material from the feeding end and form independent winding units. However, manual cutting of flat conductor materials is prone to errors due to the lack of reference points, which can lead to decreased electrical performance, increased assembly difficulty, and compromised insulation. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a transformer winding machine with infrared positioning and cutting, which solves the technical problem of lack of reference during cutting in existing semi-automatic transformer winding machines.

[0006] According to an embodiment of this utility model, a transformer winding machine with infrared positioning and cutting includes a winding head and a transformer mold disposed on the rotating shaft of the winding head. A wire storage rack is provided on one side of the winding head, and a guide rail is provided at the bottom of the winding head. A reciprocating screw is provided on the side of the guide rail away from the wire storage rack. A connecting rod is provided between the nut of the reciprocating screw and the guide rail. The connecting rod can move along the guide rail. A linear infrared emitter is provided between the winding head and the nut.

[0007] The technical principle of this utility model is as follows: the reciprocating lead screw is set on one side of the bottom of the transformer mold and away from the wire storage rack, so that after the wire is led out from the wire storage rack, it first passes through the nut of the reciprocating lead screw from the bottom of the transformer mold, and then is wound on the transformer mold. After the winding is completed, the linear infrared emitter emits a linear laser that irradiates the wire, and the operator can directly cut it along the linear laser.

[0008] At the same time, because the operator's operating position is located on one side of the reciprocating lead screw, it is also convenient for cutting.

[0009] Compared with the prior art, this utility model has the following beneficial effects: by setting a reciprocating lead screw on one side of the bottom of the transformer mold and a linear infrared emitter set between the reciprocating lead screw and the transformer mold, it solves the technical problem of lack of reference during the cutting of the existing semi-automatic transformer winding machine.

[0010] Furthermore, the outer cylindrical surface of the nut is provided with a groove, the guide rail is provided with a rotatable guide wheel, the guide wheel is connected to the connecting rod, the guide wheel can move along the guide rail, and the wire on the wire storage rack passes through the groove of the guide wheel and the nut in sequence and is wound onto the transformer mold.

[0011] By setting guide wheels and grooves, it is ensured that the led-out wire can move with the nut.

[0012] Furthermore, the reciprocating lead screw is provided with two helical grooves, and the reciprocating lead screw and the winding head are connected by a common driver.

[0013] Furthermore, the reciprocating lead screw is provided with a helical groove, and the winding head and the reciprocating lead screw are respectively connected to a driver.

[0014] Furthermore, the guide wheel includes an inner wheel and an outer wheel arranged from the inside out, with a roller between the inner wheel and the outer wheel. One side of the inner wheel is connected to a connecting rod, and the center of the inner wheel has a square hole. The square inner hole wheel is sleeved on the guide rail, and the outer cylindrical surface of the outer wheel has flanges on both sides.

[0015] Furthermore, one end of the connecting rod is provided with a trapezoidal block, the guide rail is provided with a trapezoidal groove, the trapezoidal block is inserted into the trapezoidal groove, and a cylindrical roller is provided between the trapezoidal block and the trapezoidal groove.

[0016] Furthermore, a bearing is provided between the connecting rod and the nut, with the inner ring of the bearing connected to the nut and the outer ring of the bearing connected to the connecting rod.

[0017] Furthermore, the horizontal height of the reciprocating lead screw is higher than that of the guide rail.

[0018] Furthermore, the linear laser emitted by the linear infrared emitter intersects with the wire located between the reciprocating lead screw and the transformer mold, and the angle between the wire and the linear laser is 80°-100°. Attached Figure Description

[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0027] Example 1

[0028] like Figure 1-2 The transformer winding machine with infrared positioning and cutting shown includes a winding head 1 and a transformer mold 11 set on the rotating shaft of the winding head 1. A wire storage rack 12 is provided on one side of the winding head 1, and a guide rail 2 is provided at the bottom of the winding head 1. A reciprocating screw 3 is provided on the side of the guide rail 2 away from the wire storage rack 12. A connecting rod 4 is provided between the nut 31 of the reciprocating screw 3 and the guide rail 2. The connecting rod 4 can move along the guide rail 2. Specifically, the horizontal height of the reciprocating screw 3 is higher than that of the guide rail 2. A rotatable guide wheel 21 is provided on the guide rail 2, and the guide wheel 21 is connected to the connecting rod 4.

[0029] Specifically, the reciprocating lead screw 3 has two helical grooves, and the reciprocating lead screw 3 and the winding head 1 are connected by a common driver 13, i.e., a motor. Of course, in order to ensure that the transmission speeds of the reciprocating lead screw 3 and the winding head 1 are different, a gearbox 14 needs to be set at the transmission connection between the two for speed change.

[0030] like Figure 1-2 As shown, a linear infrared emitter 5 is provided between the winding head 1 and the nut 31. Specifically, the linear laser emitted by the linear infrared emitter 5 intersects with the wire located between the reciprocating screw 3 and the transformer mold 11, and the angle between the wire and the linear laser is 80°-100°, with 90° being optimal.

[0031] During processing, the wire is drawn from the wire storage rack 12, moves along the guide wheel 21, then winds around the nut 31, and finally winds onto the transformer mold 11. During the winding process, the nut 31 moves along the guide rail 2, and the moving process will synchronously drive the connecting rod 4 and the guide wheel 21 to move along the guide rail 2. Consequently, the wire on the nut 31 and the guide wheel 21 will also move. When the winding is completed, the wire is manually cut along the linear laser to ensure that the cut surface is relatively flat and there is no tilted surface, i.e., the cut is crooked.

[0032] like Figure 1-3 As shown, the outer cylindrical surface of the nut 31 has an integrally formed groove 311. The guide wheel 21 includes an inner wheel 211 and an outer wheel 212 arranged from the inside to the outside. A roller 213 is provided between the inner wheel 211 and the outer wheel 212. One side of the inner wheel 211 is connected to the connecting rod 4. The center of the inner wheel 211 has a square hole 2111. The square inner hole wheel is sleeved on the guide rail 2. The outer cylindrical surface of the outer wheel 212 has integrally formed flanges 2121 on both sides.

[0033] like Figure 4 As shown, one end of the connecting rod 4 is integrally formed with a trapezoidal block 41, and the guide rail 2 is provided with a trapezoidal groove 22. The trapezoidal block 41 is inserted into the trapezoidal groove 22, and a cylindrical roller 411 is provided between the trapezoidal block 41 and the trapezoidal groove 22. Specifically, the cylindrical roller 411 is set at the bottom and waist of the trapezoidal block 41 to ensure smooth movement of the connecting rod 4.

[0034] like Figure 3 As shown, a bearing 42 is provided between the connecting rod 4 and the nut 31. The inner ring of the bearing 42 is connected to the nut 31, and the outer ring of the bearing 42 is connected to the connecting rod 4, ensuring that the rotation of the nut 31 will not affect the connecting rod 4.

[0035] Example 2

[0036] like Figure 5As shown, the difference between this embodiment and embodiment 1 is that: a collar 312 is provided on the outside of the nut 31, and roller-like structures 313 are evenly distributed between the collar 312 and the nut 31, forming a structure similar to a bearing 42, which can ensure that the collar 312 does not rotate when the nut 31 rotates.

[0037] Example 3

[0038] like Figure 6 As shown, the difference between this embodiment and embodiment 1 is that: the reciprocating screw 3 is provided with a spiral groove, and the winding head 1 and the reciprocating screw 3 are respectively connected to a driver 13, that is, two motors are provided for separate driving.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
