Description

Technical Field

[0001] This utility model relates to the field of audio cable production technology, specifically to an audio cable soldering equipment. Background Technology

[0002] Audio cables, also known as audio wires, are cables used to transmit electroacoustic signals or data. Broadly speaking, they fall into two main categories: electrical signals and optical signals. They consist of two parts: the audio cable itself and the connector.

[0003] Chinese Patent Publication No. CN112809119A discloses an audio cable soldering mechanism, including a base and a plug feeding device, a feeding device, an earphone cable feeding device, a wire cutting and separating device, a soldering device, and a control device, all mounted on the base. The earphone cable feeding device includes a conveying component and multiple earphone cable placement fixtures. The conveying component is mounted on the base, and each earphone cable placement fixture is mounted on the conveying component and moves with the conveying component. The wire cutting and separating device includes a wire separating frame, a wire organizing component, and a wire cutting component. The wire separating frame is mounted on the base, and the wire organizing component and the wire cutting component are sequentially arranged along the wire conveying direction. This invention effectively solves the fatigue problem of manual wire soldering by replacing manual soldering with this automated machine, and overcomes the difficulties in controlling the solder point size and low efficiency of manual soldering. Furthermore, it can effectively improve work efficiency, reduce labor costs, and increase product yield.

[0004] However, while the above technical solutions effectively address the fatigue issues of manual wire soldering by replacing manual soldering with automated machines, and solve the problems of difficulty in controlling solder point size and low efficiency in manual soldering, and can effectively improve work efficiency, in existing audio cable soldering scenarios, audio cables are usually composed of multiple strands. When soldering audio cables to connectors, workers often need to untangle and straighten the cables at both ends of the audio cable to accurately connect them to the corresponding interfaces. When workers manually untangle and straighten the cables, due to the lack of effective auxiliary tools and standardized operating methods, it is easy to cause damage such as pulling and twisting to the cables, which in turn affects the transmission performance and service life of the audio cables. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing an audio line soldering device.

[0006] The technical solution of this utility model is as follows: An audio cable soldering device, comprising a main body of the soldering device, a worktable connected to it, a belt conveyor connected to the worktable, and multiple jigs for clamping audio cables connected to the belt conveyor; a dynamic guide assembly connected to the main body of the soldering device, the dynamic guide assembly comprising a guide cylinder, a mounting cylinder, a rotating cylinder, a first telescopic device, and an arc plate, wherein a through conical hole is opened at the axial position of the guide cylinder, and the sidewall of the conical hole is projected as an arc-shaped curved surface concave inward toward the axis on its axial section; the mounting cylinder is detachably connected to a stepped section opened at one end of the guide cylinder. Inside the ladder groove, a rotating cylinder is rotatably connected to the mounting cylinder. Inside the rotating cylinder, a first telescopic device is symmetrically arranged. The telescopic end of the first telescopic device is connected to an arc-shaped plate. When the dynamic guide component is in use, one end of the bent cable is inserted into the conical through hole and is clamped and positioned by the arc-shaped plate driven by the first telescopic device. Gravity causes the cable to slide down in the conical through hole, making the bent part of the cable vertically downward. The cable management component is connected to the main body of the welding equipment. When the cable management component is in use, the moving end of the cable management component moves vertically to squeeze the multiple strands of wire core inside the cable, so that the wire core at one end of the cable changes from a circumferential distribution to a horizontal arrangement.

[0007] Preferably, the dynamic guide assembly includes a support frame connected to the worktable, and the support frame is connected to the guide cylinder.

[0008] Preferably, the cable management assembly includes a mounting frame connected to a workbench, with a fixed platform connected to the mounting frame; a second telescopic device connected to a support frame, with a movable plate connected to the telescopic end of the second telescopic device; and a pressure plate connected to the movable plate, the pressure plate having an arc-shaped cross-section.

[0009] Preferably, a plurality of positioning grooves are provided in the stepped groove at one end of the guide cylinder, and a positioning protrusion is connected on the mounting cylinder due to the cooperation of the positioning grooves.

[0010] Preferably, one end of the mounting cylinder is connected to a connecting plate, and the connecting plate is bolted to the guide cylinder.

[0011] Preferably, the conical through-hole of the guide tube is coated with a graphene composite coating.

[0012] Preferably, protective pads are connected to both sides of the curved plates.

[0013] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0014] In this invention, after the cable is inserted into the dynamic guide assembly, it rotates and slides within the guide cylinder around the central axis of the conical through hole due to its own shape and weight. One end of the cable gradually rotates towards the ground. At this time, the flattening assembly uses a pressure plate to squeeze the multiple strands of the cable at one end, changing them from a circumferential distribution to a horizontal distribution, thus reducing the steps that require manual intervention.

[0020] Example 1

[0021] like Figures 1-4 As shown, this utility model proposes an audio cable soldering device, including a soldering device body 1, a workbench 2, a belt conveyor 3, a dynamic guide assembly, and a cable management assembly. The soldering device body 1 is connected to the workbench 2, and the belt conveyor 3 is connected to the workbench 2. Multiple jigs for clamping audio cables are connected to the belt conveyor 3. The dynamic guide assembly is connected to the soldering device body 1 and includes a guide cylinder 4, a mounting cylinder 5, a rotating cylinder 6, a first telescopic device 7, and an arc plate 8. A through conical hole is opened at the axial position of the guide cylinder 4, and the projection of the sidewall of the conical hole on its axial section is an arc-shaped curved surface concave inward towards the axis. The mounting cylinder 5 is detachably connected to a stepped groove 9 opened at one end of the guide cylinder 4, and a rotating device is rotatably connected inside the mounting cylinder 5. The rotating cylinder 6 has a symmetrically arranged first telescopic device 7 connected inside. The first telescopic device 7 uses a piezoelectric ceramic actuator, which has an amplification structure that can amplify its own movement to achieve millimeter-level displacement. This structure is powered by a battery. The telescopic end of the first telescopic device 7 is connected to an arc plate 8. When the dynamic guide assembly is in use, one end of the bent cable is inserted into the conical through hole and is clamped and positioned by the arc plate 8 driven by the first telescopic device 7. Gravity causes the cable to slide down in the conical through hole, making the bent part of the cable vertically downward. The cable management assembly is connected to the main body 1 of the welding equipment. When the cable management assembly is in use, the moving end of the cable management assembly moves vertically to squeeze the multiple strands of wire core inside the cable, so that the wire core at one end of the cable changes from a circumferential distribution to a horizontal arrangement.

[0022] Example 2

[0023] like Figures 1-2 As shown, the present invention proposes an audio cable soldering device. Compared with Embodiment 1, this embodiment describes the detailed structure of the dynamic guide component. The dynamic guide component includes a support frame 10, which is connected to the workbench 2 and is connected to the guide cylinder 4. The support frame 10 has a cylindrical structure to connect the guide cylinder 4.

[0024] Example 3

[0025] like Figure 2 As shown, this utility model proposes an audio cable soldering device. Compared with Embodiment 2, this embodiment describes the detailed structure of the cable management assembly. The cable management assembly includes a mounting frame 11, a fixed platform 12, a second telescopic device 13, a moving plate 14, and a pressure plate 15. The mounting frame 11 is connected to the workbench 2, and the fixed platform 12 is connected to the mounting frame 11. A baffle is connected to the fixed platform 12, which is used to position and restrict the continued movement of the cable. The second telescopic device 13 is connected to the support frame 10, and the telescopic end of the second telescopic device 13 is connected to the moving plate 14. The second telescopic device 13 may be, but is not limited to, a cylinder or an electric push rod. The pressure plate 15 is connected to the moving plate 14, and the cross-sectional shape of the pressure plate 15 is arc-shaped. The pressure plate 15 may be selected from various types of equipment.

[0026] In an optional embodiment, a plurality of positioning grooves 16 are provided in the stepped groove 9 at one end of the guide cylinder 4, and a positioning protrusion 17 is connected to the mounting cylinder 5 due to the cooperation of the positioning grooves 16; the positioning grooves 16 cooperate with the positioning protrusions 17 to fix the guide cylinder 4.

[0027] In an optional embodiment, one end of the mounting cylinder 5 is connected to a connecting plate 18, and the connecting plate 18 is bolted to the guide cylinder 4.

[0028] In an optional embodiment, the conical through-hole of the guide cylinder 4 is coated with a graphene composite coating; the graphene composite coating can reduce the friction between the cable and the cable, and prevent the cable from sliding and rotating unevenly due to friction.

[0029] In an optional embodiment, protective pads are connected to both sides of the curved plate 8; the protective pads are made of materials such as rubber and silicone.

[0030] In summary, when using this utility model, the operator inserts the cable, whose outer insulation has been pre-cut at both ends using external equipment, into the guide cylinder 4. Before being cut to a fixed length, the cable is usually wound around a storage device, so after being unwound and cut, it typically presents an arc shape. After inserting the cable into the guide cylinder 4, the cable contacts the baffle for positioning. The first telescopic device 7 controls the arc-shaped plates 8 to move towards each other to clamp the cable. After the operator releases the cable, due to its own weight and arc shape, even if the arc shape shifts to a tilted position, it will gradually slide off due to gravity. This allows one end of the cable to point towards the ground, ensuring that different cables maintain the required angle. Then, the telescopic end of the second telescopic device 13 moves, causing the moving plate 14 and pressure plate 15 to move downwards, squeezing the cable whose outer insulation layer has been stripped. Through squeezing, the cable gradually becomes parallel. Then, the first telescopic device 7 and the second telescopic device 13 reset, and the cable is pulled out and placed on the fixture on the belt conveyor 3. The parallel cable is inserted into the predetermined groove to complete the positioning. As the belt conveyor 3 conveys the cable, it gradually approaches the welding equipment body 1, and then the cable is welded to the audio connector.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
