Description

Technical Field

[0001] This utility model relates to the field of electromagnetic component processing technology, specifically to a wire-pulling device for coils. Background Technology

[0002] A magnetic core coil is an electronic component consisting of a coil wound around a magnetic core. It is a fundamental component ubiquitous in modern electronic and electrical systems. The manufacturing process of a magnetic core coil typically includes wire drawing and winding processes. Wire drawing refers to straightening the coil wound on the base frame from its end, while winding refers to winding the coil around the magnetic core. Both are core steps in the manufacturing process of magnetic core coils, and their quality directly affects the electrical performance and reliability of the magnetic core coil.

[0003] However, the existing wire drawing process still has some shortcomings and needs to be improved for some practical functions. For example, most of the existing wire drawing process is done manually, which is inefficient, consumes relatively high time and labor costs, and produces poor quality. The coils straightened manually may be warped due to the angle deviation or excessive force, making it impossible to carry out subsequent processes. The warped coils cannot be used, resulting in waste of resources and extending the total production time of the magnetic core coil. Utility Model Content

The surface of the stretched and extended coil is always horizontal and smooth and will not be curled. This effectively improves the quality of the coil and ensures the smooth progress of the subsequent coil processing steps. Attached Figure Description

[0042] Specifically, through the cooperation of the second bottom slide 407 and the second electric guide rail 408, the rotating module 4 as a whole can be translated on the second electric guide rail 408.

[0043] Reference Appendix Figure 1-6 The working process of the coil pulling device of this utility model is as follows:

[0044] During operation, the coil body 1 is first placed in the receiving groove 3011 on the loading component 301. Then, the clamping cylinder 303 is activated. The piston rod at one end of the clamping cylinder 303 moves through the through hole 3012 and contacts and pushes the clamping block 302. After the clamping block 302 moves a certain distance inside the through hole 3012, one end of it tightly contacts and abuts against the base frame of the coil body 1, thereby achieving the clamping and fixing of the coil body 1 on the receiving groove 3011.

[0045] Then, the rotating module 4, clamping module 3, and spacing module 5 are moved a distance on the second electric guide rail 408 via the second bottom slide 407 to adjust the distance between the three and the wire pulling module 6. At this time, the coil wire end 2 is directly opposite the gap 8 of the wire end clamp 601.

[0046] Secondly, with the cooperation of the first bottom slide 6023 and the first electric guide rail 6024, the wire end clamp 601 moves horizontally towards the coil wire end 2 until one end of the coil wire end 2 is inserted into the gap 8 between the upper clamping block 6011 and the lower clamping block 6012 and stops. At this time, the distance between the first clamping block 6013 and the second clamping block 6014 is shortened by the finger cylinder 6015, thereby shortening the distance between the upper clamping block 6011 and the lower clamping block 6012, so that the upper clamping block 6011 and the lower clamping block 6012 cooperate to clamp and fix one end of the coil wire end 2.

[0047] Furthermore, the rotating table 402 drives the intermediate connecting plate 403 and the connecting base plate 401 to rotate to a certain angle. At the same time, the interval module 5 and the clamping module 3 also rotate synchronously until the coil wire end 2 on the clamping module 3 is in a horizontal state and stops. At the same time, a gap with a fixed angle is generated between the coil body 1 and the coil wire end 2.

[0048] Subsequently, the single-rod cylinder 506 of the interval module 5 is activated. The piston rod of the single-rod cylinder 506 applies a pulling force to the transmission side plate 503 towards the coil wire end 2. With the cooperation of the upper guide rail 504 and the lower guide rail 505, the transmission side plate 503 drives the connecting pad 502 and its upper end insertion piece 501 to move a distance towards the coil wire end 2. One end of the upper connecting block 5011 of the insertion piece 501 is inserted between the coil body 1 and the coil wire end 2. At the same time, the coil wire end 2 is inserted laterally into the horizontal groove 7 between the upper connecting block 5011 and the lower connecting block 5012.

[0049] Finally, with the cooperation of the first bottom slide 6023 and the first electric guide rail 6024, the wire end clamp 601 that holds and fixes one end of the coil wire end 2 moves in the opposite direction, and the coil on the coil body 1 is stretched and extended horizontally along the horizontal groove 7 by the wire end clamp 601 to enter the next process.

[0050] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
