Description

Technical Field

[0001] The utility model relates to the technical field of transformer winding, in particular to a transformer foot winding device and system. Background Art

[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] When producing transformers, the transformers need to be foot-wrapped. Transformer foot-wrapping refers to wrapping the transformer wires around the transformer terminal pins, which is often completed through a separate foot-wrapping process.

[0004] The current method for implementing transformer foot wrapping is: positioning and clamping the transformer frame on a winding fixture, and winding the terminal pins of the transformer manually or by a foot wrapping mechanism.

[0005] The transformer skeleton is only clamped by a winding jig. During the winding process, the transformer core is prone to displacement, and the stability of the transformer winding process cannot be guaranteed, thus affecting the winding quality. In addition, during the transformer winding process, due to the lack of support for the transformer winding, the winding end position changes during the winding process, which is prone to uneven force on the winding, further affecting the winding quality. When the current method is used to wrap the transformer foot, it is not possible to wrap multiple transformers at the same time, resulting in low transformer foot wrapping efficiency.

[0041] Example 1

[0042] In order to improve the quality and efficiency of transformer foot binding, in this embodiment, a transformer foot binding device is disclosed, such as Figure 1As shown, it includes a machine base 6, on which a foot-winding station is arranged, and the foot-winding station includes an upper positioning mechanism 2, a transformer fixing seat, a wire clamping mechanism 3 and a wire winding mechanism 1;

[0043] The upper positioning mechanism 2 includes a mounting bracket 2-1 and a pressing block 2-3; the pressing block 2-3 is connected to the mounting bracket 2-1 and can move up and down relative to the mounting bracket 2-1, the mounting bracket 2-1 is fixed on the machine base 6, and the pressing block 2-3 is located above the transformer fixing base;

[0044] The wire clamping mechanism 3 includes a clamping plate 3-1, a wire threading groove 3-2 is arranged on the clamping plate 3-1, a tension spring 3-3 is arranged in the wire threading groove 3-2, and the winding wire of the transformer passes through the tension spring 3-3 and comes out from the wire threading groove 3-2;

[0045] The wire winding mechanism 1 comprises a wire winding clamp 1-1 and a mounting seat 1-2. The wire winding clamp 1-1 is used to clamp the end of the wire winding passing through the threading groove; the wire winding clamp 1-1 is connected to the mounting seat 1-2 and can move up and down, left and right, and forward and backward along the mounting seat 1-2.

[0046] In order to realize the transportation of the transformer, the present embodiment further sets a transmission mechanism 4 on the machine base 6, and the transformer fixing seat is set on the transmission mechanism 4. The transmission mechanism 4 can transport the transformer fixing seat to the foot binding station and stop the transformer fixing seat under the pressing block 2-3.

[0047] In a specific implementation, the transmission mechanism 4 can be a mechanism with a transmission function such as a belt conveyor.

[0048] In order to achieve stable fixation of the transformer and prevent the transformer from shifting during the winding process, thereby affecting the quality of the winding, this embodiment stipulates that the transformer fixing seat includes a clamping mold and a magnet; the clamping mold is used to fix the transformer; the magnet is used to attract the magnetic core of the transformer fixed on the clamping mold to prevent the transformer core from shifting upward during the winding process.

[0049] In the specific implementation, for the foot binding device without a transmission mechanism, the magnet and the clamping mold are fixed on the machine base 6. For the foot binding device with a transmission mechanism, the magnet and the clamping mold are fixed on the transmission mechanism and can be transported to the foot binding station through the transmission mechanism.

[0050] When the transmission mechanism transports the transformer fixing seat to the foot binding station and stops under the pressing block 2-3, the pressing block 2-3 is controlled to move downward until the pressing block 2-3 is pressed tightly against the magnetic core of the transformer on the clamping mold, thereby achieving stable clamping of the transformer, preventing the transformer from shifting during the foot binding process, and ensuring the quality of the transformer foot binding.

[0051] like Figure 2As shown, in order to ensure the stability of the pressing block moving up and down, this embodiment stipulates that the pressing block 2-3 is also connected to the mounting bracket 2-1 through a guide rod, and the pressing block 2-3 can move up and down along the guide rod.

[0052] In order to reduce the impact force on the magnetic core of the transformer when the pressing block 2-3 moves downward to press the magnetic core, a buffer spring is arranged between the pressing block 2-3 and the mounting bracket 2-1. When the pressing block 2-3 moves downward, the buffer spring is pulled to provide a buffer for the pressing block 2-3 to press the magnetic core, thereby reducing the impact on the magnetic core when the pressing block 2-3 moves downward, thereby reducing damage to the magnetic core.

[0053] In specific implementation, guide rods and buffer springs are respectively arranged on both sides of the pressure block 2-3. The pressure block 2-3 can move up and down along the two guide rods. The two buffer springs are respectively sleeved on the outside of the two guide rods to ensure that the pressure block 2-3 is subjected to balanced force.

[0054] In this embodiment, the pressing block 2-3 is connected to the telescopic member 2-2, the telescopic member 2-2 is fixed on the mounting bracket 2-1, and the telescopic member 2-2 can drive the pressing block 2-3 to move up and down.

[0055] The telescopic part 2-2 can be a cylinder, which is installed on the mounting bracket 2-1. The pressure block 2-3 is located below the mounting bracket 2-1. The piston rod of the cylinder passes through the mounting bracket 2-1 and is connected to the pressure block 2-3. The extension and retraction of the cylinder piston rod drives the pressure block 2-3 to move downward and upward.

[0056] In addition, in order to adapt to the foot binding of transformers of different specifications, the present embodiment also connects the mounting bracket 2-1 with the telescopic mechanism 2-4, the telescopic mechanism 2-1 is connected with the fixed seat 2-5, the fixed seat 2-5 is connected with the machine base 6, and the telescopic mechanism 2-4 can drive the mounting bracket 2-1 to move up and down, thereby adjusting the height of the upper positioning mechanism 2.

[0058] In specific implementation, the clamping plate 3-1 is located between the transformer fixing seat and the winding mechanism. Two wire threading grooves 3-2 are set on the clamping plate 3-1 for each transformer. The two ends of the transformer winding wire extend from the two wire threading grooves 3-2 respectively to realize the winding of the transformer.

[0059] A tensioning spring 3-3 is arranged in each wire threading groove 3-2, and the axial direction of the tensioning spring 3-3 is perpendicular to the direction in which the transformer wire passes through the wire threading groove 3-2, and the transformer wire passes through the tensioning spring 3-3 and extends out of the wire threading groove 3-2, so that the tensioning spring 3-3 has a certain tensioning effect on the wire, thereby preventing the wire from loosening during the transformer foot winding process and affecting the transformer foot winding quality.

[0060] like Figure 2 As shown, the wire winding mechanism 1 is arranged on one side of the transformer fixing seat, and includes a wire winding clamp 1-1 and a mounting seat 1-2. The wire winding clamp 1-1 is used to clamp the end of the wire winding passed through the threading groove 3-2. The wire winding clamp 1-1 is connected to the lifting mechanism 1-3, and the lifting mechanism 1-3 can drive the wire winding clamp 1-1 to move up and down. The lifting mechanism 1-3 is connected to the cross slide 1-4, and the cross slide 1-4 can drive the lifting mechanism 1-3 to move forward and backward and left and right, so as to realize the up and down, left and right and forward and backward movement of the wire winding clamp 1-1. The cross slide 1-4 is connected to the mounting seat 1-2.

[0061] In a specific implementation, the lifting mechanism 1-3 and the cross slide 1-4 can be realized by linear guide rails. When winding the transformer pins, the end of the winding wire passing through the threading groove 3-2 is clamped by the winding clamp 1-1, and the winding clamp 1-1 is controlled to move up and down, left and right, and forward and backward to wind the transformer winding wire on the transformer pins.

[0062] The transformer foot-binding device disclosed in this embodiment can also perform foot-binding on multiple transformers at the same time. Specifically, a plurality of foot-binding stations are arranged on the machine base 6, and each foot-binding station has the same structure.

[0063] Specifically, Figure 3 As shown, the foot-winding station includes an upper positioning mechanism 2, a wire clamping mechanism 3, a wire winding mechanism 1 and a plurality of transformer fixing seats;

[0064] The upper positioning mechanism 2 includes a mounting bracket 2-1 and a plurality of pressing blocks 2-3, wherein the plurality of pressing blocks 2-3 are arranged one by one above the plurality of transformer fixing seats, and the plurality of pressing blocks are connected to the mounting bracket 2-1 and can move up and down relative to the mounting bracket 2-1;

[0067] When it is necessary to wrap the feet of multiple transformers at the same time, the multiple transformers are placed on multiple transformer fixing seats respectively, and the magnetic core of each transformer is attracted by a magnet. Then, the multiple pressing blocks are controlled to move downward until the magnetic core of each transformer is pressed by the multiple pressing blocks; the ends of the winding wires of the multiple transformers are connected to the multiple winding clamps 1-1 one by one, and the lifting mechanism and the cross slide are controlled to move, so as to realize the simultaneous winding of the feet of the multiple transformers and improve the winding efficiency of the transformers.

[0068] Each foot-binding station of the present embodiment also has a blowing mechanism 5, which includes a blowing pipe 5-1 and a collecting box. The mouth of the blowing pipe 5-1 faces the winding end of the transformer fixed on the transformer fixing seat. After the transformer foot is wrapped, a certain amount of waste wire will be generated. The blowing pipe 5-1 can blow the waste wire away from the station. The collecting box is located on the machine base 6 and is used to collect the thread ends blown off by the blowing pipe.
