Description

Technical Field

[0001] The invention relates to the technical field of conductive material processing, in particular to a process for automatically tinning the middle section of an enameled wire. Background Art

[0002] Enameled wire is a wire with an insulating coating on the surface of the wire. It is most widely used in the electronics and medical industries. However, in actual use, in order to facilitate the subsequent wire connection, it is often necessary to tin the middle of the enameled wire (see Figure 1 ), after tinning, the enameled wire can effectively prevent corrosion, fix, prevent oxidation and improve electrical safety.

[0003] The existing process generally uses a cutter or paint stripper to remove the surface coating of the middle part that needs to be tinned, and then uses a soldering iron tip or a solder ball to manually tin it. This process is complex and difficult to operate, has low efficiency, unstable tinning quality, and uncontrollable tinning length and size, high scrap rate, and has a great impact on subsequent processes. It takes up a lot of manpower in mass production. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the prior art and provide a process for automatically tinning the middle section of an enameled wire.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] The technical solution of the present invention is to provide a process for automatically tinning the middle section of an enameled wire, comprising the following steps:

[0007] S1. Install the enameled wire reel on the empty reel of the wire feeding stepper motor, and its end passes through the tensioner and the wire pulley in turn and enters the laser area and the tin spraying area, and is finally fixed to the empty reel of the wire taking-up stepper motor. The wire taking-up stepper motor tightens the enameled wire, and the left-rotating clamp and the right-rotating clamp in the laser area and the tin spraying area are controlled by the electric cylinder to clamp the enameled wire;

[0008] S2, laser zone removes coatings on opposite sides of the enameled wire located between the left rotating clamp and the right rotating clamp by laser;

[0009] S3, the left-rotating clamp and the right-rotating clamp rotate 90°, so that the enameled wire also rotates 90°, and then the coatings on the opposite sides of the enameled wire located between the left-rotating clamp and the right-rotating clamp are removed by laser;

[0010] S4, the left-rotating clamp and the right-rotating clamp rotate 90° in opposite directions to reset the enameled wire;

[0011] S5, the left rotating clamp and the right rotating clamp move the enameled wire to the tin spraying area, and tin spray the enameled wire from which the coating has been removed;

[0012] S6, the left rotating clamp and the right rotating clamp release the enameled wire and then reset, and the wire-reeling stepper motor rewinds the wire to the set length;

[0013] S7. Repeat steps S2 to S6.

[0014] In some specific embodiments, in step S1, the enameled wire between the tensioner and the wire pulley forms a V-shape.

[0015] In some specific embodiments, the angle of the V-shape formed is 30-60°.

[0016] In some specific embodiments, in step S1, after the enameled wire passes through the wire pulley, it also passes through the threading shaft to be guided into the laser zone.

[0017] In some specific embodiments, in step S2, the laser zone is provided with an upper laser and a lower laser, and the coatings on the upper and lower sides of the enameled wire between the left rotating clamping jaw and the right rotating clamping jaw are removed by laser respectively.

[0018] In some specific embodiments, in step S3, the left-rotating jaw and the right-rotating jaw are rotated 90° clockwise, so that the enameled wire between the left-rotating jaw and the right-rotating jaw is also rotated 90° clockwise.

[0019] In some specific embodiments, in step S4, the left-rotating jaw and the right-rotating jaw are rotated 90° counterclockwise, so that the enameled wire between the left-rotating jaw and the right-rotating jaw is also rotated 90° counterclockwise to be reset.

[0020] In some specific implementations, in step S5, the wire feeding stepper motor, the wire taking-up stepper motor, and the electric cylinder are started simultaneously, so that the left rotating clamp and the right rotating clamp move the enameled wire to the tin spraying area.

[0021] In some specific implementations, in step S5, the tin-spraying area is provided with a tin-spraying furnace located at the bottom of the enameled wire.

[0022] In some specific embodiments, in step S5, when spraying tin, the left rotating jaw and the right rotating jaw rotate the enameled wire so that the tin is sprayed on the outer peripheral surface of the coating removal area of ​​the enameled wire.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] (1) The present invention controls the tensioning force of the enameled wire by utilizing the V-shaped torque formed between the tensioner and the wire pulley, which can adapt to enameled wires of different wire diameters and effectively prevent the enameled wire from being stretched or broken due to excessive tension.

[0025] (2) Through the irradiation of the upper laser and the lower laser, and the flipping of the left-rotating clamp and the right-rotating air gripper, the coating on all sides of the enameled wire can be completely removed, ensuring the comprehensiveness of the coating removal.

[0026] (3) The length tolerance of the tinning on the enameled wire is effectively guaranteed by synchronizing the wire-receiving stepper motor and the wire-feeding stepper motor.

[0027] (4) The enameled wire is tinned using a tin spraying furnace, which realizes the process of automatic tinning in the middle section of the enameled wire and ensures efficient and stable tinning quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Embodiment 1:

[0035] like Figures 2-3 As shown, a process for automatically tinning the middle section of an enameled wire includes the following steps:

[0036] (1) The enameled wire 6 is mounted on the empty reel of the wire feeding stepper motor 1, and its end passes through the tensioner 2 and the wire pulley 3 in turn, and enters the laser zone and the tin spraying zone under the guidance of the threading shaft 4, and finally fixed to the empty reel of the wire taking-up stepper motor 9. The wire taking-up stepper motor 9 tightens the enameled wire, and the left rotating clamp 12 and the right rotating clamp 6 clamp the enameled wire 8, and the electric cylinder 7 controls the movement between the laser zone and the tin spraying zone. The enameled wire 8 between the tensioner 2 and the wire pulley 3 forms a V shape with an angle of about 45°.

[0037] (2) The laser zone is provided with an upper laser 5 and a lower laser 11 symmetrically disposed on both sides of the enameled wire 8, and the coatings on the upper and lower sides of the enameled wire 8 located between the left rotating clamp 12 and the right rotating clamp 6 are removed by laser respectively.

[0038] (3) The left-rotating jaw 12 and the right-rotating jaw 6 rotate 90° clockwise, so that the enameled wire 8 also rotates 90°, and then the coating on the other opposite sides of the enameled wire 8 located between the left-rotating jaw 12 and the right-rotating jaw 6 is removed by laser using the upper laser 5 and the lower laser 11, respectively, thereby completing the complete removal of the coating.

[0039] (4) The left-rotating clamping jaw 12 and the right-rotating clamping jaw 6 are rotated counterclockwise by 90° again, so that the enameled wire 8 between the left-rotating clamping jaw 12 and the right-rotating clamping jaw 6 is reset.

[0040] (5) The wire-receiving stepper motor 9, the wire-feeding stepper motor 1, and the electric cylinder 7 are started synchronously, and the left-rotating clamp 12 and the right-rotating clamp 6 move the enameled wire 8 to the tin-spraying area, so that the tin-spraying furnace 10 located in the tin-spraying area at the bottom of the enameled wire 8 sprays tin on the enameled wire 8 where the coating is removed. When spraying tin, the left-rotating clamp 12 and the right-rotating clamp 6 rotate the enameled wire 8 so that the outer peripheral surface of the enameled wire 8 where the coating is removed is evenly sprayed with tin.

[0041] (6) The left-rotating clamping jaw 12 and the right-rotating clamping jaw 6 release the enameled wire 8, the electric cylinder 7 resets the left-rotating clamping jaw 12 and the right-rotating clamping jaw 6, and the wire-rewinding stepping motor 9 rewinds the wire to a set length.

[0042] (7) Repeat steps (2) to (6) to tin the next position on the enameled wire 8.

[0043] In some specific embodiments, in step S1, the enameled wire between the tensioner and the wire pulley forms a V-shape.

[0044] The above description of the embodiments is to facilitate the understanding and use of the invention by those skilled in the art. It is obvious that those skilled in the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work.
