Description
Technical Field
[0001] This utility model relates to the field of winding machine technology, specifically to an automatic winding machine clamp capable of cutting the wire. Background Technology
[0002] Transformers are widely used in production. A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The coil is an important component of the transformer. Currently, transformer coils are basically made by automatic winding machines, and the clamp is a component of the winding machine.
[0003] In actual production, some special transformers require "tail wire" in their design. "Tail wire" refers to leaving a section of unwound wire at the beginning and end of the winding process for subsequent connections and processing, such as welding, crimping, and connecting to external circuits or other windings. In some strict cases, transformers have specific requirements regarding the length and position of the tail wire. Most existing automatic winding machines lack a cutting mechanism in their clamping area, making it impossible to complete the tail wire leaving process. The usual practice is to cut the tail wire manually. However, manual cutting inevitably involves contact with the coil, causing damage or contamination; furthermore, manually cut tail wires are inconsistent in length, failing to meet the relevant technical requirements for the reserved tail wire length. Utility Model Content
[0004] The purpose of this utility model is to provide an automatic winding machine fixture that can cut the wire and flexibly cut the tail wire to the required length according to the needs, so as to solve the problem mentioned in the background art that the tail wire length cut manually is inconsistent and cannot meet the relevant technical requirements.

One end of the support rod 2 is vertically connected to the side wall of the support arm 1, and the other end extends horizontally to one side of the support arm 1. The transformer bracket 3 is connected to the extended end of the support rod 2 and is used for winding the wire. A groove 21 is formed on the top surface of the support rod 2 along its length, and a plurality of mounting holes 22 are formed in the groove 21 along its length. A positioning post 4 is erected in each mounting hole 22. A cutter 5 is arranged beside the positioning post 4, and the wire is wound in a figure-eight shape on the cutter 5 and the positioning post 4. A wire pulling mechanism 6 is arranged beside the support rod 2 to break the wire wound on the cutting edge of the cutter 5. In this embodiment, the wire is copper wire.
[0028] Please see Figure 5 The support rod 2 is equipped with a guide wheel 7 located between the cutter 5 and the transformer bracket 3, and the axis of the guide wheel 7 is perpendicular to the horizontal plane. The outer circumference of the guide wheel 7 is recessed towards its axis to form an arc-shaped groove 71, which is used to accommodate the wire. The guide wheel 7 is used to guide the wire onto the cutter 5 and also to tension the wire.
[0029] This utility model uses a transformer bracket 3 to wind the wire. Before or after winding, the end of the wire leading out from the transformer passes through the cutter 5 and the positioning post 4 in sequence and is folded back to the cutter 5. The positioning post 4 fixes and positions the wire. Finally, the wire folded back to the cutter 5 is pulled off by the wire pulling mechanism 6, thereby achieving the purpose of leaving a tail wire. Furthermore, by installing the positioning post 4 at different mounting holes 22, the required tail wire length can be flexibly cut according to the needs.
[0030] The transformer support 3 includes two opposing baffles 31 and a spindle 32 connected between the two baffles 31. One of the baffles 31 is connected to the extended end of the support rod 2, and the wire is wound around the spindle 32. In this embodiment, the top surfaces of both baffles 31 are provided with a plurality of slots 311, and a protruding ridge 312 for the wire to pass through is formed between adjacent slots 311. The sidewalls of the two baffles 31 facing away from the spindle 32 are provided with a plurality of hanging rods 33 for winding the end of the wire.
[0031] Please see Figure 4 The positioning post 4 includes a straight rod section 41, a screw section 42 connected to the bottom end of the straight rod section 41, and a flange section 43 connected to the top end of the straight rod section 41. The lower part of the straight rod section 41 is inserted into the groove 21, and the upper part of the straight rod section 41 is used to wind the wire. The screw section 42 is inserted into the mounting hole 22 on the bottom wall of the groove 21. The flange section 43 protrudes from the outer peripheral surface of the straight rod section 41 to prevent the wire from falling off the positioning post 4.
[0032] Please see Figure 3The cutter 5 includes a cutter holder 51 and a cutter body 52 detachably mounted on the cutter holder 51. One end of the cutter holder 51 has a groove 511 for accommodating the cutter body 52, and the other end has an arc-shaped surface 512 facing away from the groove 511. The arc-shaped surface 512 guides the wire through the groove, preventing it from being scratched. The end of the cutter body 52 facing away from the arc-shaped surface 512 is shaped like a sharp blade. The arc-shaped surface 512 has several screw holes 513 communicating with the groove 511. Bolts 514 threadedly connected to the cutter body 52 are placed within the screw holes 513. The cutter body 52 can be replaced by loosening the bolts 514, facilitating future maintenance. In this embodiment, a retaining portion 515 extending towards the cutter body 52 is formed at the top of the groove 511. The retaining portion 515 prevents the wire from falling off the cutter body 52. The end of the retaining portion 515 has a rounded corner to prevent scratching the wire.
[0033] Please see Figure 1-2 The wire pulling mechanism 6 includes a bracket 61 mounted on the side wall of the support arm 1 and a pulling cylinder 62 mounted on the bracket 61. The bracket 61 and the support rod 2 are located on the same side of the support arm 1. The wire drawn from the cutter 5 is connected to one end of the piston rod of the pulling cylinder 62. In this embodiment, the wire pulling mechanism 6 includes a support block 63 connected to the piston rod of the pulling cylinder 62 and a column 64 erected on the support block 63. The finishing wire drawn from the cutter 5 is wound around the column 64. The pulling cylinder 62 drives the column 64 on the support block 63 to pull the wire, thereby cutting the wire at the position of the cutter 5.
[0034] The working principle of this automatic winding machine clamp capable of breaking wires is as follows:
[0035] The end of the wire drawn from the transformer is wound in a figure-eight shape onto the guide wheel 7, the cutter 5, and the positioning post 4, and the wire folded back to the cutter 5 is guided to the post 64 on the support block 63. After the wire is stably wound on the post 64, the pulling cylinder 62 is activated. The pulling cylinder 62 pulls the wire through its piston rod, causing the wire located at the cutting edge of the cutter 5 to break, so as to leave a tail wire. Finally, the broken tail wire is removed from the positioning post 4 and the cutter 5.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
