Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wire harness processing technology, and specifically relates to a wire twisting device for a tinning machine. Background Technology
[0002] A tinning machine is an automated piece of equipment used in the electronics manufacturing industry. It is mainly used for processes such as cutting, stripping, twisting, tinning, and crimping terminals of wires.
[0003] There are various types of soldering machines on the market, each with different designs and structures. To prevent the wire core from unraveling after cutting and stripping, some wires must be twisted before soldering. Generally, twisting is necessary when the stripped length is long. Because the twisting devices vary, the twisting effect also differs. If the wire needs to be inserted into a hole on a circuit board after soldering, the twisting must be flat and even. Currently, during the twisting process of soldering machines, the wire is prone to arching or shifting, resulting in loose and uneven twisting, which affects the subsequent soldering quality and the reliability of the connection.

[0011] Preferably, the fixing block is provided with a wire sleeve, which is disposed through the fixing block, and one end of the wire sleeve is disposed facing the wire clamping groove. The wire sleeve is used to limit the extension direction of the wire harness.
[0012] Preferably, the rotating mechanism includes a rotating motor and a rotating platform.

The telescopic cylinder of the clamping mechanism drives the first clamping block to cooperate with the second clamping block to clamp the wire harness. The translation mechanism drives the rotation mechanism and the clamping mechanism to move in the soldering area to solder the wire harness.

The downstream soldering machine wire feeding module clamps the wire harness and pulls it out from between the first and second clamping blocks, which facilitates the downstream tangent module to cut the wire. The entire twisting process is prevented from shifting or loosening due to the action of the clamping mechanism.
[0019] 2. The twisting device of this utility model further restricts the wire harness from shifting or loosening by setting the wire sleeve. Attached Figure Description

The embodiments of this utility model will now be described based on its overall structure.
[0032] like Figures 1-5 As shown, this embodiment provides a wire twisting device for a soldering machine. The wire twisting device is installed on the working platform of the soldering machine, which has a soldering area and a wire cutting area. The wire twisting device is located between the soldering area and the wire cutting area; it includes:
[0033] Rotating mechanism 2 is mounted on translation mechanism 1. Rotating mechanism 2 can drive the wire harness to twist towards the soldering area and the tangent area respectively.
[0034] Translation mechanism 1 is installed on the working platform of the tinning machine. Translation mechanism 1 can drive rotation mechanism 2 to move from the position corresponding to the tinning area to the position corresponding to the tangent area.
[0035] The wire clamping mechanism 3 includes a telescopic cylinder 31, a fixed block 32, a first clamping block 51, a second clamping block 52, and a sensor. The fixed end of the telescopic cylinder 31 is fixed to one side of the fixed block 32, and the movable end of the telescopic cylinder 31 passes through the fixed block 32 and can telescopically move relative to the fixed block 32. The fixed block 32 is fixed to the rotating mechanism 2 and rotates with the rotating mechanism 2. A clamping groove is provided on the side of the fixed block 32 away from the telescopic cylinder 31. The first clamping block 51 is fixed in the clamping groove. The two sides of the second clamping block 52 are connected to the two side walls of the clamping groove through a rotating shaft. The second clamping block 52 is rotatably connected to the rotating shaft. The movable end of the telescopic cylinder 31 is connected to one end of the second clamping block 52, and the other end of the second clamping block 52 cooperates with the first clamping block 51 to clamp the wire harness. The sensor is set on the mating surface of the first clamping block 51 or the second clamping block 52.
[0036] Specifically, the tinning area is the functional module area where the tinning machine tins the wire harness, and the cutting area is where the tinning machine cuts the tinned wire harness, completes the processing, and collects it. When tinning multiple wire harnesses at once, the driving cylinder 11 of the translation mechanism 1 is required to drive the wire harnesses one by one for tinning. After tinning is completed, the rotating mechanism 2 rotates the extension direction of the wire harness, and the translation mechanism 1 pushes it towards the cutting area so that the wire harness can be pulled to the cutting area by the downstream wire feeding functional module.
[0037] Both the first clamping block 51 and the second clamping block 52 have wire clamping grooves on their opposing surfaces, and the cross-section of the wire clamping grooves is arc-shaped or triangular. By setting the opposing surfaces of the first clamping block 51 and the second clamping block 52 to be arc-shaped or triangular, it is convenient to clamp wire harnesses of different specifications.
[0038] The fixing block 32 is provided with a wire sleeve 6, which passes through the fixing block 32. One end of the wire sleeve 6 faces the wire clamping groove. The wire sleeve 6 is used to restrict the extension direction of the wire bundle. Specifically, the wire sleeve 6 ensures that the wire bundle can only extend along the axial direction of the wire sleeve 6, thus preventing deviation or loosening.
[0039] The rotating mechanism 2 includes a rotating motor 21 and a rotating platform 22. The fixed end of the rotating motor 21 is fixed on the translation mechanism 1, and the rotating platform 22 and the output shaft of the rotating motor 21 are fixedly connected. The fixing block 32 is fixed on the rotating platform 22.
[0040] The fixed block 32 is provided with an adjustment groove, and the rotating platform 22 is provided with a threaded hole. A connecting rod is threaded into the threaded hole, and the part of the connecting rod outside the threaded hole passes through the adjustment groove and is connected to the fixed block 32 by a nut. With this design, the position of the fixed block 32 on the rotating platform 22 can be adjusted.
[0041] The translation mechanism 1 includes a drive cylinder 11 and an assembly platform 12. The fixed end of the drive cylinder 11 is fixed on the working platform of the soldering machine, the assembly platform 12 is fixed on the movable end of the drive cylinder 11, and the rotation mechanism 2 is fixed on the assembly platform 12.
[0042] The first clamping block 51 and the second clamping block 52 each have multiple clamping slots, and the first clamping block 51 and the second clamping block 52 correspond one-to-one. With this design, multiple wire harnesses can be clamped simultaneously.
[0043] The twisting device also includes a guiding mechanism 4, which includes a guide rail 41 and a guide block 42. The guide block 42 is fixed to the side wall of the assembly platform 12. The guide rail 41 extends parallel to the moving end of the drive cylinder 11, and the guide block 42 is slidably connected to the guide rail 41. The assembly platform can be guided by the guiding mechanism.
[0044] Principle: The telescopic cylinder 31 of the wire clamping mechanism 3 drives the first clamping block 51 to cooperate with the second clamping block 52 to clamp the wire harness. The translation mechanism 1 drives the rotation mechanism 2 and the wire clamping mechanism 3 to move in the tinning area to tin the wire harness. After tinning is completed, the rotation mechanism 2 first drives the wire clamping mechanism 3 to rotate, so that the wire harness faces the downstream tangent area. The translation mechanism 1 drives the rotation mechanism 2 and the wire clamping mechanism 3 to move towards the tangent area. After moving into position, the telescopic cylinder 31 drives the first clamping block 51 to move away from the second clamping block 52. The downstream tinning machine wire feeding function module clamps the wire harness and pulls it out from between the first clamping block 51 and the second clamping block 52, which facilitates the downstream tangent function module to cut the wire. During the entire twisting process, the wire clamping mechanism 3 ensures that the wire harness will not shift or loosen.
