Description

Technical Field

[0001] The present application relates to the field of bending jigs, and in particular to a winding jig and a processing technology for an inductor coil. Background Art

[0002] In the electronics manufacturing industry, spiral copper tubes, as a core conductive material for inductor coils, are widely used in coils, windings and other structures of various electronic products. As electronic products develop towards miniaturization and integration, the processing technology of spiral copper tubes has also put forward higher requirements. Especially in the bending process after the spiral copper tube is formed, how to efficiently and accurately complete the bending of a specific shape has become one of the focuses of the industry. Traditional manual bending is not only inefficient, but also difficult to ensure consistency, and cannot meet the requirements of modern industry for high precision and mass production.

[0003] In response to the above needs, the industry usually uses single-function mechanical equipment to complete bending actions of different shapes. For example, a set of equipment is used to complete straight-line bending first, and then another set of equipment is used to complete curve bending.

[0004] The above solution has the following defects: since multiple single-function mechanical equipment are required to perform processing in sequence, the processing steps of the spiral copper tube are relatively complicated. Summary of the invention

[0005] In order to simplify the processing steps of a spiral copper tube, the present application provides a winding jig and a processing technology for an inductor coil.

[0006] The present application provides a coil winding jig adopting the following technical solution: A winding jig for an inductor coil comprises a base, a positioning mechanism, an L-shaped bending mechanism and an S-shaped bending mechanism, wherein the base comprises a bottom plate and a side plate vertically connected to the bottom plate; one end of the bottom plate in the width direction is hinged to the side plate; The positioning mechanism includes a positioning column, which is arranged above the bottom plate along the length direction of the bottom plate and one end of which is connected to the bottom plate; The L-shaped bending mechanism is installed on the side plate, and the L-shaped bending mechanism includes a fan-shaped ring and a side movable bracket. The fan-shaped ring is installed on a side of the side plate facing the positioning column, and the outer side wall is provided with a shaping groove arranged along the circumference of the fan-shaped ring; the side movable bracket is arranged at an end of the side plate away from the positioning column, and is rotatably connected to the side plate with the axis of the fan-shaped ring as the center of the circle; the side movable bracket is provided with a side groove wheel arranged opposite to the shaping groove; The S-shaped bending mechanism is mounted on the bottom plate and is located on a side of the positioning column away from the side plate; the S-shaped bending mechanism comprises a first guide groove wheel, a second guide groove wheel and a first bottom positioning pin, in the width direction of the bottom plate, the first guide groove wheel and the first bottom positioning pin are both arranged on a side of the second guide groove wheel away from the positioning column, and the first guide groove wheel and the second guide groove wheel are staggered; The end of the first guide groove wheel away from the base plate is connected to a rotatable and liftable first rotating bracket, and the first rotating bracket is equipped with a first pressure groove wheel arranged opposite to the first guide groove wheel; the end of the second guide groove wheel away from the base plate is connected to a rotatable and liftable second rotating bracket, and the second rotating bracket is equipped with a second pressure groove wheel arranged opposite to the second guide groove wheel.

[0007] By adopting the above technical solution, the function of bending one end of the spiral copper tube into an L shape and the other end into an S shape is realized. The specific effects are as follows: the design of the base, including the bottom plate and the side plate, provides a stable support platform for the entire fixture, ensuring the stability during the bending process. The positioning column in the positioning mechanism can accurately fix the position of the spiral copper tube to avoid displacement during the bending process, thereby ensuring the bending accuracy. The L-shaped bending mechanism presses the spiral copper tube into the shaping groove through the side groove wheel, and rolls from one end of the shaping groove to the other end, so that the first end of the spiral copper tube can be accurately pressed into an L shape. When the S-shaped bending mechanism is running, the first guide groove wheel and the second guide groove wheel clamp the second end of the spiral copper tube to limit the second end of the spiral copper tube. The first bottom positioning pin is disassembled to guide the second end of the spiral copper tube to enter between the first pressing groove wheel and the second guide groove wheel, the first pressing groove wheel and the first guide groove wheel clamp the second end of the spiral copper tube, and the first rotating bracket rotates so that the first pressing groove wheel presses the spiral copper tube on the second guide groove wheel, thereby realizing the first bending of the second end of the spiral copper tube. Then, the first bottom positioning pin is reset, and the first rotating bracket rises. At this time, the first bottom positioning pin is located between the second end of the spiral copper tube and the first guide groove wheel. The first rotating bracket does not interfere with the secondary deformation of the second end of the spiral copper tube. Then the second rotating bracket rotates, and the second pressing groove wheel presses the second end of the spiral copper tube to the first guide groove wheel. Under the cooperation of the second pressing groove wheel and the first bottom positioning pin, the second end of the spiral copper tube is bent for the second time, so that the second end of the spiral copper tube becomes S-shaped. One end of the bottom plate in the width direction is hinged to the side plate. In the actual processing process, the two ends of the spiral copper tube will not be exactly vertical, and there are some angle errors at both ends of the spiral copper tube. When the positioning column is loaded, the side plate is rotated to make it coplanar with the bottom plate. At this time, even if the angle between the two ends of the spiral copper tube is an obtuse angle, it can be smoothly put on the positioning column, and then the side plate is reset to perform bending processing, which improves the loading efficiency. And the hinged design between the bottom plate and the side plate makes the overall structure of the bending jig have a certain flexibility. This design allows the bottom plate to be adjusted in angle relative to the side plate, so as to better adapt to spiral copper tubes of different specifications or different bending process requirements.

[0008] In summary, the various components work together to bend the two ends of the spiral copper tube on a bending jig, which improves production efficiency. Preferably, a bottom fixture capable of being embedded in the bottom plate is provided on a side of the positioning column away from the side plate, the bottom fixture comprising a bottom lifting plate and a bottom hinged plate, the bottom lifting plate being movably mounted on the bottom plate; in the length direction of the positioning column, the bottom hinged plate is hinged to the bottom lifting plate; The distance between the first guide groove wheel and the second guide groove wheel is adjustable.

[0009] By adopting the above technical solution, before the spiral copper tube is loaded, the bottom hinged plate rotates until it is coplanar with the bottom lifting plate, the bottom lifting plate shrinks into the bottom plate, and the distance between the first guide groove wheel and the second guide groove wheel increases. After the spiral copper tube is loaded, the second end of the spiral copper tube can be just located above the bottom lifting plate and between the first guide groove wheel and the second guide groove wheel. At this time, the bottom lifting plate extends to a position that matches the first guide groove wheel and the second guide groove wheel. The bottom hinged plate rotates to match the bottom lifting plate to clamp the second end of the spiral copper tube, so that the second end of the spiral copper tube can be matched with the first guide groove wheel and the second guide groove wheel. Then the distance between the first guide groove wheel and the second guide groove wheel is reduced, clamping the second end of the spiral copper tube, so that the second end of the spiral copper tube can quickly match with the first guide groove wheel and the second guide groove wheel. Finally, the bottom clamp is away from the spiral copper tube and does not interfere with the bending of the spiral copper tube.

[0010] Preferably, in the length direction of the bottom plate, one end of the first guide groove wheel is rotatably connected to the bottom plate and is also slidably connected to the bottom plate.

[0015] By adopting the above technical solution, before the spiral copper tube is loaded, the side hinged plate rotates until it is coplanar with the side lifting plate, the side lifting plate shrinks into the side plate, and the distance between the side groove wheel and the shaping groove increases. After the spiral copper tube is loaded, the first end of the spiral copper tube can be located exactly opposite the side lifting plate and between the side groove wheel and the shaping groove. At this time, the side lifting plate is extended to a position that matches the shaping groove and the side groove wheel. The side hinged plate rotates to match the side lifting plate to clamp the first end of the spiral copper tube, so that the first end of the spiral copper tube can be matched with the shaping groove and the shaping groove. Then the distance between the shaping groove and the side groove wheel is reduced, clamping the first end of the spiral copper tube, so that the first end of the spiral copper tube can quickly match with the shaping groove and the side groove wheel. Finally, the side clamp is away from the spiral copper tube and does not interfere with the bending of the spiral copper tube.

[0016] Preferably, in the radial direction of the sector ring, the side movable bracket is telescopically mounted on the side plate.

[0020] Preferably, two second bottom positioning pins are symmetrically arranged on a side of the first bottom positioning pin away from the positioning column, and the second bottom positioning pins are installed on the bottom plate in a liftable and / or detachable manner.

[0021] By adopting the above technical solution, the two second bottom positioning pins clamp the second end of the spiral copper tube. When the second end of the spiral copper tube is deformed for the first time, the second end of the spiral copper tube can be guided between the two second bottom positioning pins, and a preliminary guidance is performed on the first deformation of the second end of the spiral copper tube to ensure the bending accuracy.

[0022] Preferably, the shaping groove is provided with two symmetrically arranged second side positioning pins at one end away from the positioning column, and the second side positioning pins are arranged along the axial centerline direction of the fan-shaped ring, and in the axial centerline direction of the fan-shaped ring, the second side positioning pins are telescopically and / or detachably installed on the side plate.

[0023] By adopting the above technical solution, the two second side positioning pins clamp the first end of the spiral copper tube. When the first end of the spiral copper tube is deformed for the first time, the first end of the spiral copper tube can be guided between the two second side positioning pins, and a preliminary guidance is performed on the first deformation of the first end of the spiral copper tube to ensure the bending accuracy.

[0036] Reference Figure 1 and Figure 2 In the implementation mode of the present application, the function of bending one end of the spiral copper tube into an L shape and the other end into an S shape is realized. The specific effects are as follows: The design of the base 1, including the bottom plate 11 and the side plate 12, provides a stable support platform for the entire fixture, ensuring stability during the bending process. The positioning column 21 in the positioning mechanism 2 can accurately fix the position of the spiral copper tube to avoid displacement during the bending process, thereby ensuring the bending accuracy. The L-shaped bending mechanism 3 presses the spiral copper tube into the shaping groove 3101 through the side groove wheel 321, and rolls from one end of the shaping groove 3101 to the other end, so that the first end of the spiral copper tube can be accurately pressed into an L shape.

Under the cooperation of the second pressing groove wheel 422 and the first bottom positioning pin 43, the second bending of the second end of the spiral copper tube is performed, so that the second end of the spiral copper tube becomes S-shaped. In summary, all components work together to bend both ends of the spiral copper tube on a bending jig, which improves production efficiency. ReferenceFigure 1 and Figure 2 , one end of the bottom plate 11 in the width direction is hinged to the side plate 12.

[0049] After the spiral copper tube is loaded, the first end of the spiral copper tube can be exactly located opposite the side lifting plate 231 and between the side groove wheel 321 and the shaping groove 3101. At this time, the side lifting plate 231 is extended to a position that matches the shaping groove 3101 and the side groove wheel 321. The side hinge plate 232 rotates to match the side lifting plate 231 to clamp the first end of the spiral copper tube, so that the first end of the spiral copper tube can be matched with the shaping groove 3101 and the shaping groove 3101. Then, the distance between the shaping groove 3101 and the side groove wheel 321 is reduced, clamping the first end of the spiral copper tube, so that the first end of the spiral copper tube can quickly match with the shaping groove 3101 and the side groove wheel 321.

[0050] After the spiral copper tube is loaded, the second end of the spiral copper tube can be just located above the bottom lifting plate 221 and between the first guide groove wheel 41 and the second guide groove wheel 42. At this time, the bottom lifting plate 221 is extended to a position that matches the first guide groove wheel 41 and the second guide groove wheel 42. The bottom hinge plate 222 rotates to match the bottom lifting plate 221 to clamp the second end of the spiral copper tube, so that the second end of the spiral copper tube can be matched with the first guide groove wheel 41 and the second guide groove wheel 42. Then, the distance between the first guide groove wheel 41 and the second guide groove wheel 42 is reduced, clamping the second end of the spiral copper tube, so that the second end of the spiral copper tube can quickly match with the first guide groove wheel 41 and the second guide groove wheel 42.

[0051] The L-shaped bending mechanism 3 presses the spiral copper tube into the shaping groove 3101 through the side groove wheel 321, and rolls from one end of the shaping groove 3101 to the other end, so that the first end of the spiral copper tube can be accurately pressed into an L shape. When the S-shaped bending mechanism 4 is in operation, the first guide groove wheel 41 and the second guide groove wheel 42 clamp the second end of the spiral copper tube to limit the second end of the spiral copper tube. The first bottom positioning pin 43 is disassembled to guide the second end of the spiral copper tube to enter between the first pressing groove wheel 412 and the second guide groove wheel 42. The first pressing groove wheel 412 and the first guide groove wheel 41 clamp the second end of the spiral copper tube, and the first rotating bracket 411 rotates so that the first pressing groove wheel 412 presses the spiral copper tube onto the second guide groove wheel 42, thereby realizing the first bending of the second end of the spiral copper tube. Then, the first bottom positioning pin 43 is reset, and the first rotating bracket 411 rises. At this time, the first bottom positioning pin 43 is located between the second end of the spiral copper tube and the first guide groove wheel 41. The first rotating bracket 411 does not interfere with the secondary deformation of the second end of the spiral copper tube. Then, the second rotating bracket 421 rotates, and the second pressing groove wheel 422 presses the second end of the spiral copper tube toward the first guide groove wheel 41. Under the cooperation of the second pressing groove wheel 422 and the first bottom positioning pin 43, the second end of the spiral copper tube is bent for the second time, so that the second end of the spiral copper tube becomes S-shaped.
