Detailed Description

Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.

Please refer to fig. 1 to fig. 3, which are schematic structural diagrams of a coil quick positioning and straightening mechanism according to the present invention. A coil quick positioning straightening mechanism is used for stretching and straightening a coil and comprises a feeding device 10, a horizontal positioning device 20, a vertical positioning device 30 and a coil straightening device 40. The coil is wound on the feeding device 10, and one end of the coil sequentially passes through the horizontal positioning device 20, the vertical positioning device 30 and the coil straightening device 40. It is contemplated that the coil quick positioning and straightening mechanism has other functional components and specific structures, such as electrical connection components, mounting structures, etc., which are well known to those skilled in the art, and therefore, will not be described in detail herein.

The feeding device 10 comprises a rotary chassis 11 and a middle bracket 12 arranged on the rotary chassis 11, and the coil is wound on the middle bracket 12. The intermediate support 12 is used as a carrier of the coil and is matched with a portal frame structure to facilitate the carrying of the coil. When one end of the coil is stressed and stretched, the stress of the middle bracket 12 placed on the rotating chassis 11 is transferred to the rotating chassis 11, so that the driven rotation of the rotating chassis 11 is matched with the coil in the feeding device 10 to discharge.

A guide wheel 13 is arranged between the feeding device 10 and the horizontal positioning device 20. The guide wheel 13 can be used for guiding the coil discharging and pre-deformation treatment.

The horizontal positioning device 20 comprises a horizontal base 21, at least four horizontal straightening wheels 22 which are sequentially arranged on two sides of the upper end of the horizontal base 21 in a staggered mode, a horizontal straightening driving structure 23 for driving the horizontal straightening wheels 22 to rotate, and a straightening channel I24 which is arranged between the horizontal straightening wheels 22 along the length direction of the horizontal base 21. The horizontal straightening driving structure 23 drives the horizontal straightening wheels 22 to rotate rapidly, so that the horizontal two sides of the coil penetrating through the straightening channel I24 are stressed all the time, and positioning and primary guiding in the horizontal direction of the coil can be completed. It is conceivable that there is a gap between the horizontal straightening wheels 22 and the horizontal base 21, or a bearing structure is provided between the horizontal straightening wheels 22 and the horizontal base 21, so as to ensure that the horizontal straightening wheels 22 can rotate relative to the horizontal base 21,

the vertical positioning device 30 comprises a vertical connecting plate 31, at least four vertical straightening wheels 32 which are sequentially arranged at the upper end and the lower end of one side of the vertical connecting plate 31 in a staggered manner, a vertical straightening driving structure 33 for driving the vertical straightening wheels 32 to rotate, and a straightening channel II 34 which is arranged between the vertical straightening wheels 32 along the length direction of the vertical connecting plate 31. The horizontal straightening wheel 22 is driven to rotate rapidly by the vertical straightening driving structure 33, so that the two vertical sides of the coil passing through the second straightening channel 34 are stressed all the time, and the positioning and the primary guiding in the vertical direction of the coil can be completed. In this embodiment, it is conceivable that, since the coil in the feeding device 10 is horizontally placed for discharging, and the coil is horizontally deformed, the coil needs to pass through the horizontal positioning device 20 for pre-processing deformation, and when the coil in the feeding device 10 is vertically placed for discharging, the coil is selected to pass through the vertical positioning device 30 for pre-processing deformation. It is contemplated that the vertical straightening wheels 32 may be spaced from the vertical connecting plate 31, or a bearing structure may be provided therebetween, to ensure that the vertical straightening wheels 32 can rotate relative to the vertical connecting plate 31,

the coil straightening device 40 comprises a housing 41, a feeding pipe 42 and a discharging pipe 43 respectively arranged at two straightening ends in a penetrating way, and a straightening structure 44 arranged in the housing 41. The straightening structure 44 includes two pinch rollers 441 vertically spaced apart and disposed in the housing 41 on a side thereof adjacent to the feed pipe 42, two drive rollers 442 vertically spaced apart and disposed in the housing 41 on a side thereof adjacent to the discharge pipe 43, a rotary drive structure 443 connected to the drive rollers 442, and a connecting pipe 444 disposed between the pinch rollers 441 and the drive rollers 442. The rotary driving structure 443 drives the driving roller 442 to rotate, so as to provide forward feeding power for the coil. The first straightening channel 24, the second straightening channel 34, the feeding pipe 42, the connecting pipe 444 and the discharging pipe 43 are located on the same straight line, and the structure can ensure that the coil is always kept in a straight line state in the straightening process, so that the straightening stability is improved.

The middle part of the circumferential outer wall of each clamping roller 441 is provided with a first annular groove 441a, the first annular grooves 441a on the two clamping rollers 441 correspondingly form a first clamping hole for a coil to pass through, and the inner diameter of the first clamping hole is smaller than or equal to the outer diameter of the coil. The driving roller 442 is provided with a second annular groove 442a at the middle of the circumferential outer wall thereof, and the second annular groove 442a of the two driving rollers 442 correspondingly forms a second clamping hole for the coil to pass through. The inner diameter of the second clamping hole is smaller than or equal to the outer diameter of the coil. The holding roller 441 and the driving roller 442 respectively hold both ends of the coil in the housing 41, and when the driving roller 442 rotates and applies a force to one end of the coil, the both ends of the coil are kept in a tensioned state, and the coil is further stretched and straightened. The structure design of the clamping roller 441 and the driving roller 442 enables the coil to be in rolling conveying with the clamping roller 441 and the driving roller 442 during stretching and straightening, and excessive abrasion of the surface of the coil is avoided. The connection tube 444 serves as a guide support for the coil in the housing 41.
