[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Existing coil winding forming equipment can usually only adapt to winding rollers of specific specifications. In actual production, it may be necessary to wind coils on winding rollers of different specifications, which reduces the versatility of the equipment and makes it impossible to make quick adjustments between various products, thus affecting production efficiency.

[0022] To address the defects observed during the use of the aforementioned winding device, please refer to [link / reference needed]. Figures 1-4 This utility model provides a transformer coil winding forming device that can fix winding rollers 65 of different lengths, expanding the applicability of the equipment. The winding forming device uses a base 1 as its foundation. A side frame 2 is fixedly installed on one side of the top of the base 1, and a feeding roller 3 is installed on one side of the side frame 2. Supports 4 are symmetrically installed on the other side of the top of the base 1. A slide rod 5 is fixedly installed between the two supports 4. A winding mechanism 6 is provided on the slide rod 5, which includes a swing platform 61 slidably sleeved outside the slide rod 5. A bidirectional screw 62 is rotatably installed inside the swing platform 61. The threads on the outer surface of the bidirectional screw 62 are two segments with opposite directions of rotation. Both ends of the bidirectional screw 62 are threadedly connected to a slide 63. The bottom of the slide 63 is slidably connected to the inner wall of the swing platform 61. A connector 64 is provided on one side of the slide 63, and a winding roller 65 is installed between the two connectors 64. The slide 63 can fix the winding roller 65 through the connectors 64. A knob that acts on the bidirectional screw 62 is installed at one end of the swing platform 61. Rotating the knob can drive the bidirectional screw 62 to rotate. The rotation of the bidirectional screw 62 can drive the two slides 63 to move closer or further apart. The distance between the two slides 63 can be adjusted according to the size of the winding roller 65, so that the slide 63 can fix winding rollers 65 of different lengths.

[0023] To achieve the fixing effect of the connector 64 on the winding roller 65, the connector 64 is configured as a rotating shaft 641 rotatably mounted on the side of the slide 63. Multiple circumferentially evenly distributed retaining strips 642 are fixedly connected to the outside of the rotating shaft 641. Both ends of the winding roller 65 are provided with retaining grooves 68. A positioning plate 643 is also fixedly sleeved on the outside of the rotating shaft 641. The positioning plate 643 is located at the end of the retaining strips 642 away from the winding roller 65. The winding roller 65 is inserted into one of the rotating shafts 641. Rotating the bidirectional screw 62 drives the two slides 63 to move closer to each other, so that the other rotating shaft 641 is inserted into the other end of the winding roller 65. The positioning plate 643 can position the two ends of the winding roller 65. Due to the function of the retaining strips 642, the winding roller 65 can be driven to rotate synchronously when the rotating shaft 641 rotates, realizing the winding operation.

[0024] To achieve automatic winding of the equipment, a servo motor 67 is fixedly installed on one side of one of the slides 63. The output end of the servo motor 67 passes through the slide 63 and is fixedly connected to the axis of the rotating shaft 641. The coil end on the pay-off roller 3 is fixed on the winding roller 65. Driving the servo motor 67 can drive the rotating shaft 641 to rotate, which in turn can drive the winding roller 65 to rotate, winding the coil on the pay-off roller 3 onto the winding roller 65.

[0025] If the winding roller 65 is fixed during winding, the coil will accumulate at a certain position on the winding roller 65. To solve this technical problem, an adjusting component 66 is provided on one of the brackets 4 to drive the swing table 61 to slide along the slide bar 5. The adjusting component 66 is set as a servo motor 661 fixedly installed on the bracket 4. The output end of the servo motor 661 is fixedly connected to a connecting rod 662. An extension rod 663 is slidably connected to the outside of the connecting rod 662. The end of the extension rod 663 is rotatably connected to a connecting rod 664. The end of the connecting rod 664 is rotatably installed on one side of the bottom of the swing table 61. Driving the servo motor 661 can drive the connecting rod 662 to rotate. The rotation of the connecting rod 662 can drive the extension rod 663 to rotate. The rotation of the extension rod 663 drives the swing table 61 to slide back and forth through the connecting rod 664, thereby realizing the back and forth sliding of the winding roller 65, so that the coil can be evenly wound on the surface of the winding roller 65.

[0026] Since the winding rollers 65 of different lengths need to slide back and forth over different distances to ensure that the coil can be fully wrapped around the outside of the winding rollers 65, multiple equally spaced fixing holes 665 are provided on the connecting rod 662. The bottom of the extension rod 663 is equipped with a fastening bolt 666, the upper end of which extends into any fixing hole 665. The overall length of the connecting rod 662 and the extension rod 663 can be adjusted by the fastening bolt 666, thereby adjusting the sliding distance of the swing table 61. This allows the equipment to adaptively adjust the sliding distance of the winding rollers 65 according to their length, further improving the practicality of the equipment.

[0027] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0028] It should be noted that, in this document, the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0029] 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.
