Description

Technical Field

[0001] The present invention relates to the technical field of winding machines, in particular to a wire breaking mechanism. Background Art

[0002] In the existing network transformer manufacturing process, after the T1 ring is wound, the lengths of the four wire ends and the four wire tails are the same. To find two suitable wire strands from these eight wires and then wind the T2 ring requires manual work using eyes and hands. It is easy to make mistakes, resulting in unqualified products and causing many inconveniences in the subsequent manufacturing process. If the eight wires are pre-cut before the T1 ring is wound, and their lengths are inconsistent, and then the T1 is wound and pulled off from the pre-cut position, a wound T1 ring with inconsistent head and tail wire lengths can be obtained, which is conducive to the continuous progress of subsequent processes.

[0003] Patent CN104795233B discloses a wire-cutting mechanism for a winding machine. This mechanism can pre-cut eight enameled wires before winding them in the T1 loop. The pre-cut lengths are inconsistent, and then the wires are pulled apart from the pre-cut position after the T1 loop is completed, facilitating subsequent processes. However, the pairwise clamping blocks used in the wire-cutting structure of this mechanism are less than ideal for clamping the enameled wire. In actual operation, the wire may not be broken, resulting in errors in the wire length, which has a negative impact on subsequent production. This problem needs to be addressed.

[0024] like Figures 1 to 10As shown, in this embodiment, the mounting base plate 1 of this embodiment and the tail wire clamping assembly 2, vertical wire arrangement assembly 3, horizontal wire arrangement assembly 4, clamping ring assembly 5, moving ring assembly 6 and driving assembly 7 are arranged on the mounting base plate 1 in a coordinated manner. The clamping ring assembly 5 and the moving ring assembly 6 are slidably arranged on the mounting base plate 1. The clamping ring assembly 5 is connected to the moving ring assembly 6 through a spring 9. The moving ring assembly 6 is transmission-connected to the driving assembly 7. The moving ring assembly 6 is provided with a sensing member 10. The mounting base plate 1 is provided with a light source that cooperates with the sensing member 10. An electric switch 11, the photoelectric switch 11 cooperates with the clamping ring assembly 5 and the driving assembly 7, and a waste clamping assembly 8 is provided on one side of the tail wire clamping assembly 2. The tail wire clamping assembly 2 includes a fixed plate 21 arranged on the mounting base plate 1, and a wire inlet 22 is provided on the fixed plate 21. An upper pressure block 23 is provided above the wire inlet 22, and a tail wire clamping cylinder 24 is provided below the wire inlet 22. A lower pressure block 25 is provided at the output end of the tail wire clamping cylinder 24, and a serrated groove 26 cooperating with the lower pressure block 25 is provided at the upper end of the lower pressure block 25.The tail wire clamping assembly 2, the vertical wire management assembly 3, the horizontal wire management assembly 4, the clamping ring assembly 5 and the movable ring assembly 6 are connected in sequence. The tail wire clamping assembly 2 is used to clamp the tail end of the wire and cooperate with the clamping ring assembly 5 to pull the wire from the pre-broken position; the vertical wire management assembly 3 is used to straighten the wire from the vertical direction, and the horizontal wire management assembly 4 is used to straighten the wire from the horizontal direction. The two components cooperate to organize the wires to facilitate the movement of other components; the clamping ring assembly 5 is used to clamp the T1 ring so that the wire can be pulled off; the movable ring assembly 6 is used to remove the T1 ring from the The left side of the tail wire clamping assembly 2, i.e., the feeding side, is carried into the clamping ring assembly 5, so that the clamping ring assembly 5 clamps the T1 ring, and is further connected to the clamping ring assembly 5 through the spring 9, thereby driving the clamping ring assembly 5 to move to the right, so that the clamping ring assembly 5 can perform the wire breaking operation; the driving assembly 7 is used to drive the moving ring assembly 6 to move left and right, and indirectly drive the clamping ring assembly 5 to move; the spring 9 connects the clamping ring assembly 5 and the moving ring assembly 6. When the driving assembly 7 drives the moving ring assembly 6 to move to the right, the spring 9 will be stretched. At this time, the clamping ring assembly 5 has not moved. When After being stretched to the longest distance, the spring 9 pulls the clamping ring assembly 5 to move to the right, so that the clamping ring assembly 5 moves one step slower than the moving ring assembly 6, thereby ensuring that the moving ring assembly 6 can send the T1 ring into the clamping ring assembly 5 and be clamped by the clamping ring assembly 5; the photoelectric switch 11 and the sensor 10 are used to sense the movement of the moving ring assembly 6, so that the moving distance of the moving ring assembly 6 can be obtained, thereby controlling whether the driving assembly 7 stops and whether the clamping ring assembly 5 performs the clamping action; the waste clamping assembly 8 is used to pull The remaining tail wires after breaking are clamped and collected for centralized processing, while ensuring that the waste tail wires do not affect the continuous operation of the entire mechanism; the tail wire clamping assembly 2 is composed of a fixed plate 21, an upper pressure block 23, a tail wire clamping cylinder 24 and a lower pressure block 25. The wire inlet 22 is opened on the fixed plate 21 for feeding the T1 ring. The tail wire clamping cylinder 24 drives the lower pressure block 25 and the upper pressure block 23 to perform a wire pressing action to press the tail wire for breaking. The serrated groove 26 is provided at the upper end of the lower pressure block 25, which is conducive to pressing the wire, and the serrated groove can prevent the wire from sliding and causing wire breaking failure.As can be seen from the above, the present invention can break the pre-broken enameled wire, thereby obtaining a T1 ring with different lengths of head and tail wires, which is convenient for subsequent processes. In addition, the present invention adopts the cooperation of the photoelectric switch 11 and the sensing component 10, so that the driving component 7 drives the moving ring component 6 to move a precise distance. At the same time, the clamping ring component 5 can accurately clamp the T1 ring, thereby improving the overall working accuracy. The lower pressing block of the tail wire clamping component 2 adopts a serrated groove structure, which can ensure the clamping of the wire, and will not cause the wire to slide under force and be broken, thereby ensuring the progress of the wire breaking work.

[0025] In this embodiment, the movable ring assembly 6 includes a first movable block 61 slidably mounted on the mounting base plate 1. The first movable block 61 is in transmission engagement with the drive assembly 7. A ring-attracting column 62 is horizontally mounted on one end of the first movable block 61, adjacent to the clamping ring assembly 5. A ring-attracting magnet 63 is disposed at the distal end of the ring-attracting column 62. The first movable block 61 is driven by the drive assembly 7 to slide left and right, thereby moving the ring-attracting column 62. The ring-attracting magnet 63 is used to attract the T1 ring, thereby moving the T1 ring. The ring-attracting magnet 63 then engages with the clamping ring assembly 5 to clamp the T1 ring for the next step.

[0026] In this embodiment, the clamping ring assembly 5 includes a second movable block 51 slidably arranged on the mounting base plate 1, an upper clamping ring block 52 is provided at the upper end of the second movable block 51, a clamping ring cylinder 53 is provided on the second movable block 51, and a lower clamping ring block 54 is provided at the output end of the clamping ring cylinder 53 to cooperate with the upper clamping ring block 52, the gap between the upper clamping ring block 52 and the lower clamping ring block 54 cooperates with the suction ring column 62, the two ends of the spring 9 are respectively connected to the first movable block 61 and the second movable block 51, and the clamping ring cylinder 53 cooperates with the photoelectric switch 11. When the movable ring assembly 6 drives the T1 ring to move, the photoelectric switch 11 is triggered, and the clamping ring cylinder 53 waits for action. When the T1 ring is driven between the upper clamping ring block 52 and the lower clamping ring block 54, the clamping ring cylinder 53 is actuated to clamp the T1 ring, and at this time the second movable block 51 is pulled to the right by the spring 9 until the pre-breaking point of the tail wire of the T1 ring is disconnected, and the wire breaking is completed.

[0027] In this embodiment, the drive assembly 7 includes a drive motor 71, a first drive wheel 72, and a second drive wheel 73, all of which are arranged on the mounting base 1.

The first movable block 61 is connected to the transmission belt 74. The drive motor 71 cooperates with the photoelectric switch 11. The drive motor 71 drives the first drive wheel 72 to rotate, and drives the second drive wheel 73 to move via the transmission belt 74. The first movable block 61 is connected to the transmission belt 74. Therefore, the first movable block 61 is driven by the drive motor 71 to move left and right. The photoelectric switch 11 cooperates with the drive motor 71 to control the driving time of the drive motor 71, so that the moving distance of the first movable block 61 is within a set control range.

[0028] In this embodiment, the vertical cable management assembly 3 includes a vertical cylinder 31 mounted on the mounting base 1. The vertical cylinder 31 opens and closes vertically relative to the mounting base 1. A connecting plate 32 is provided at the output end of the vertical cylinder 31, and a vertical cable management block 33 is mounted on the connecting plate 32. The vertical cylinder 31 drives the vertical cable management block 33 up and down via the connecting plate 32, thereby vertically limiting the enameled wire on the T1 ring, confining it to a specific range and achieving the cable management purpose.

[0029] In this embodiment, the horizontal cable management assembly 4 includes a horizontal cylinder 41 disposed on the mounting base 1. An upper cable management block 42 is disposed above the horizontal cylinder 41. A lower cable management block 43 is disposed at the output end of the horizontal cylinder 41, which cooperates with the upper cable management block 42. The gap between the upper cable management block 42 and the lower cable management block 43 is parallel to the gap between the upper clamping ring block 52 and the lower clamping ring block 54. The horizontal cylinder 41 drives the lower cable management block 43 to press together with the upper cable management block 42, thereby limiting the horizontal position of the enameled wire of the T1 ring. This, in conjunction with the vertical cable management assembly 3, achieves an ideal effect.

[0030] In this embodiment, the waste material clamping assembly 8 includes a cylinder mounting block 81, one end of which is provided with a waste wire clamping claw 82, and the other end of which is provided with a waste wire clamping cylinder 83. The waste wire clamping cylinder 83 controls the opening and closing of the waste wire clamping claw 82 via a connecting rod mechanism 84. The waste wire clamping claw 82 is located between the tail wire clamping assembly 2 and the water-line wire management assembly 4. The waste wire clamping cylinder 83 drives the waste wire clamping claw 82 to open and close via the connecting rod mechanism 84, thereby clamping the waste tail wire remaining after the wire is cut, thereby facilitating the collection and processing of the waste wire.

[0031] In this embodiment, the end faces of the upper pressing block 23 and the lower pressing block 25 are stepped. The mating end faces of the upper pressing block 23 are uneven, which can fold the end of the wire and facilitate breaking the wire.

[0032] Although the embodiments of the present invention are described with practical solutions, they do not limit the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
