Description

TECHNICAL FIELD

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

[0002] In the electronic manufacturing industry, spiral copper pipes, as a kind of core conductive material for inductor coils, are widely used in the coils and windings of various electronic products. With the development of electronic products towards miniaturization and integration, higher requirements are put forward for the processing technology of spiral copper pipes. Especially in the bending process after the spiral copper pipe 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 not only has low efficiency, but also cannot guarantee consistency, and cannot meet the requirements of modern industry for high precision and mass production.

[0003] In view of the above-mentioned needs, the industry usually uses single-function mechanical equipment to complete different shapes of bending actions respectively, for example, first completing straight-line bending by one set of equipment and then completing curve bending by another set of equipment.

[0004] The above-mentioned scheme has the following defects: since multiple single-function mechanical equipment are needed to process in sequence, the processing steps of the spiral copper pipe are relatively complicated. SUMMARY

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

[0006] The coiling jig for an inductor coil provided by the present application adopts the following technical scheme:

[0007] A coiling jig for an inductor coil, comprising a base, a positioning mechanism, an L-shaped bending mechanism and an S-shaped bending mechanism, the base comprising a bottom plate and a side plate connected perpendicularly to the bottom plate; one end of the bottom plate in the width direction is hinged to the side plate;

[0008] The positioning mechanism comprises 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;

[0009] The L-shaped bending mechanism is installed on the side plate, the L-shaped bending mechanism comprising a sector ring and a side movable support, the sector ring being installed on one side of the side plate facing the positioning column, and a shaped groove being arranged on the outer side wall of the sector ring along the circumferential direction of the sector ring; the side movable support is arranged at one end of the side plate away from the positioning column, and is rotationally connected to the side plate with the axis of the sector ring as the center; the side movable support is provided with a side groove wheel arranged opposite to the shaped groove;

[0010] The S-shaped bending mechanism is installed on the bottom plate and located at the 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 at the 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 distributed in a staggered manner.

[0011] One end of the first guide groove wheel away from the bottom plate is connected with a rotatable and liftable first rotating support, and the first rotating support is installed with a first pressing groove wheel arranged opposite to the first guide groove wheel; one end of the second guide groove wheel away from the bottom plate is connected with a rotatable and liftable second rotating support, and the second rotating support is installed with a second pressing groove wheel arranged opposite to the second guide groove wheel.

[0012] By adopting the above technical scheme, the function of bending one end of the spiral copper pipe 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 whole jig, ensuring the stability during the bending process. The positioning column in the positioning mechanism can accurately fix the position of the spiral copper pipe, avoiding deviation during the bending process, thereby ensuring the bending accuracy. The L-shaped bending mechanism presses the spiral copper pipe against the shaping groove through the side groove wheel, and rolls from one end of the shaping groove to the other end, which can accurately press the first end of the spiral copper pipe into an L shape. When the S-shaped bending mechanism operates, the first guide groove wheel and the second guide groove wheel clamp the second end of the spiral copper pipe, limiting the second end of the spiral copper pipe. The first bottom positioning pin is disassembled, guiding the second end of the spiral copper pipe into the space between the first pressure groove wheel and the second guide groove wheel, the first pressure groove wheel and the first guide groove wheel clamp the second end of the spiral copper pipe, the first rotating support rotates, and the first pressure groove wheel presses the spiral copper pipe against the second guide groove wheel, thereby realizing the first bending of the second end of the spiral copper pipe. Then, the first bottom positioning pin is reset, and the first rotating support rises, at this time the first bottom positioning pin is located between the second end of the spiral copper pipe and the first guide groove wheel, the first rotating support does not interfere with the second end of the spiral copper pipe for secondary deformation, then the second rotating support rotates, the second pressure groove wheel presses the second end of the spiral copper pipe towards the first guide groove wheel, and under the cooperation of the second pressure groove wheel and the first bottom positioning pin, the second end of the spiral copper pipe is bent for the second time, making the second end of the spiral copper pipe into an S shape. 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 pipe are not perpendicular to each other, and there is an angle error between the two ends of the spiral copper pipe. When loading the positioning column, the side plate is rotated to be coplanar with the bottom plate. At this time, even if the included angle between the two ends of the spiral copper pipe is obtuse, the spiral copper pipe can also be smoothly fitted on the positioning column. Then the side plate is reset for bending processing, improving the loading efficiency. The hinge design between the bottom plate and the side plate makes the overall structure of the bending jig flexible. This design allows the bottom plate to be adjusted relative to the side plate, thereby better adapting to different specifications of the spiral copper pipe or different bending process requirements.

DETAILED DESCRIPTION

[0046] The following will be described in detail below with reference to the accompanying drawings. Figures 1-2 The application will be described in further detail.

[0047] The embodiment of the application discloses a coiling jig and processing technology of an inductor coil.

[0048] Reference Figure 1 and Figure 2 A coiling jig of an inductor coil comprises a base 1, a positioning mechanism 2, an L-shaped bending mechanism 3 and an S-shaped bending mechanism 4. The base 1 comprises a bottom plate 11 and a side plate 12 connected perpendicularly to the bottom plate 11. The positioning mechanism 2 comprises a positioning column 21 arranged above the bottom plate 11 along the length direction of the bottom plate 11 and connected to the bottom plate 11 at one end.

[0049] Reference Figure 1 and Figure 2 The L-shaped bending mechanism 3 is installed on the side plate 12. The L-shaped bending mechanism 3 comprises a sector ring 31 and a side movable support 32. The sector ring 31 is installed on one side of the side plate 12 facing the positioning column 21, and a shaping groove 3101 is arranged on the outer side wall of the sector ring 31 along the circumferential direction of the sector ring 31. The side movable support 32 is arranged at one end of the side plate 12 away from the positioning column 21 and is rotationally connected to the side plate 12 with the axis of the sector ring 31 as the center. The side movable support 32 is driven to rotate by a side motor, realizing the automation of rotation. The side movable support 32 is provided with a side groove wheel 321 arranged opposite to the shaping groove 3101.

[0050] Reference Figure 1 and Figure 2, S-shaped bending mechanism 4 is installed on the bottom plate 11 and is located on the side of the positioning column 21 away from the side plate 12. The S-shaped bending mechanism 4 comprises a first guide groove wheel 41, a second guide groove wheel 42 and a first bottom positioning pin 43, in the width direction of the bottom plate 11, the first guide groove wheel 41 and the first bottom positioning pin 43 are both arranged on the side of the second guide groove wheel 42 away from the positioning column 21, and the first guide groove wheel 41 and the second guide groove wheel 42 are distributed in staggered positions.

[0051] Referring to Figure 1 and Figure 2 , one end of the first guide groove wheel 41 away from the bottom plate 11 is connected with a rotatable and liftable first rotating support 411, here the first rotating support 411 is driven to lift by a first air cylinder or other telescopic member, and a first motor for driving the first rotating support 411 to rotate is installed on the first air cylinder, and a first pressing groove wheel 412 opposite to the first guide groove wheel 41 is installed on the first rotating support 411. One end of the second guide groove wheel 42 away from the bottom plate 11 is connected with a rotatable and liftable second rotating support 421, here the second rotating support 421 is driven to lift by a second air cylinder or other telescopic member, and a second motor for driving the second rotating support 421 to rotate is installed on the second air cylinder, and a second pressing groove wheel 422 opposite to the second guide groove wheel 42 is installed on the second rotating support 421.

[0052] Referring to Figure 1 and Figure 2In the present embodiment, the function of bending one end of the spiral copper pipe into an L shape and the other end into an S shape is achieved. 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 jig, ensuring stability during the bending process. The positioning column 21 in the positioning mechanism 2 can accurately fix the position of the spiral copper pipe, avoiding deviation during the bending process, thereby ensuring bending accuracy. The L-shaped bending mechanism 3 presses the spiral copper pipe against the shaping groove 3101 through the side groove wheel 321, and rolls from one end of the shaping groove 3101 to the other end, accurately pressing the first end of the spiral copper pipe into an L shape. When the S-shaped bending mechanism 4 operates, the first guide groove wheel 41 and the second guide groove wheel 42 clamp the second end of the spiral copper pipe, limiting the second end of the spiral copper pipe. The first bottom positioning pin 43 is removed, guiding the second end of the spiral copper pipe into the space 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 pipe, and the first rotating bracket 411 rotates, causing the first pressing groove wheel 412 to press the spiral copper pipe against the second guide groove wheel 42, thereby achieving the first bending of the second end of the spiral copper pipe. 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 pipe and the first guide groove wheel 41, and the first rotating bracket 411 does not interfere with the second deformation of the second end of the spiral copper pipe. Then, the second rotating bracket 421 rotates, and the second pressing groove wheel 422 presses the second end of the spiral copper pipe towards 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 pipe is bent for the second time, causing the second end of the spiral copper pipe to become S-shaped. In summary, the cooperation of various components bends both ends of the spiral copper pipe on one bending jig, improving production efficiency

[0053] With reference to Figure 1 and Figure 2 , one end of the bottom plate 11 in the width direction is hinged to the side plate 12.

When loading the positioning column 21, rotate the side plate 12 so that it is coplanar with the bottom plate 11. Even if the included angle between the two ends of the spiral copper pipe is obtuse, the spiral copper pipe can still be smoothly fitted onto the positioning column 21. Then, reset the side plate 12 for bending processing, improving the loading efficiency. The hinge design between the bottom plate 11 and the side plate 12 makes the overall structure of the bending jig flexible. This design allows the bottom plate 11 to be adjusted in angle relative to the side plate 12, better adapting to different specifications of spiral copper pipes or different bending process requirements.

The distance between the first guide groove wheel 41 and the second guide groove wheel 42 is adjustable. In the embodiment of the application, before the spiral copper pipe is fed, the bottom hinged plate 222 is rotated until it is coplanar with the bottom lifting plate 221, the bottom lifting plate 221 is retracted into the bottom plate 11, and the distance between the first guide groove wheel 41 and the second guide groove wheel 42 is increased. After the spiral copper pipe is fed, the second end of the spiral copper pipe can be located just above the bottom lifting plate 221 and between the first guide groove wheel 41 and the second guide groove wheel 42, and at this time, the bottom lifting plate 221 is extended to a position matched with the first guide groove wheel 41 and the second guide groove wheel 42, the bottom hinged plate 222 is rotated to match the bottom lifting plate 221 to clamp the second end of the spiral copper pipe, so that the second end of the spiral copper pipe can be matched in position 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 to clamp the second end of the spiral copper pipe, so that the second end of the spiral copper pipe can be quickly matched in position with the first guide groove wheel 41 and the second guide groove wheel 42. Finally, in order not to interfere with the bending of the spiral copper pipe, the bottom clamp 22 is away from the spiral copper pipe.

Finally, in order not to interfere with the bending of the spiral copper pipe, the side clamp 23 is away from the spiral copper pipe.

[0059] Referring to Figure 1 and Figure 2 , in the radial direction of the fan ring 31, the side movable support 32 is telescopically installed on the side plate 12.
