Description

Technical Field

[0001] This utility model belongs to the field of wire straightening and feeding technology, specifically relating to a wire straightening and feeding mechanism for plug assembly. Background Technology

[0002] As consumers' living standards continue to improve, household appliances have become increasingly common, and almost every household relies on them. Examples include water heaters, microwave ovens, rice cookers, and electric kettles. The plug with the cord has become a crucial connection between these appliances and external AC power. However, existing connectors with corrective mechanisms for wire feeding devices are inconvenient to adjust the distance between the pulleys, making them unsuitable for correcting different types of wires.

[0003] Therefore, a wire feeding device with a straightening mechanism for connector production, disclosed in publication number "CN213326049U", includes a straightening mechanism comprising a mounting plate, mounting holes, a displacement bracket, a threaded rod, and a slider. The mounting plate has mounting holes at both ends, and the displacement bracket is located at the front of the mounting plate. The threaded rod is rotatably connected to the inner side of the displacement bracket, and the slider is threadedly connected to the threaded rod. One end of the threaded rod is connected to a driving mechanism. Sliding rods are slidably connected to the slider on both sides of the threaded rod. A second base is located at the top of the slider, and a second pulley is rotatably connected to the second base. A first base is mounted on the displacement bracket. This invention uses a threaded rod and a slider, which allows for easy adjustment of the distance between the first and second pulleys, thus facilitating the straightening of different wires.

[0004] However, for the aforementioned wire feeding device with a straightening mechanism used in connector production, although the tension of pulley one and pulley two on the wire can be controlled by adjusting the position between the first base and the second base according to different wire types, thus adapting to different wire raw materials, the following obvious defects still exist during use: The device straightens and feeds the wire by adjusting the tension of pulley one and pulley two on the wire. Since there is a gap between pulley one and pulley two, the wire is prone to bending downwards at the gap between the pulleys during straightening and feeding. This causes the wire to bend and straighten continuously between the pulley gaps, resulting in the internal core breaking. Utility Model Content

[0005] The purpose of this utility model is to provide a wire straightening and feeding mechanism for plug assembly, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wire straightening and feeding mechanism for plug assembly, comprising:

[0007] The wire feeding fixing plate is frame-shaped with an opening on one side. Its upper end is pneumatically equipped with a lifting wire feeding and straightening positioning roller for pressing, straightening, and feeding the wire. Corresponding to the lifting wire feeding and straightening positioning roller, a fixed wire feeding and straightening positioning roller is provided on its bottom side for supporting and positioning the wire straightening and feeding. At the feeding end of the lifting wire feeding and straightening positioning roller, a pressure roller A is pneumatically provided to press down and maintain a horizontal straight state during wire feeding. On one side of pressure roller A, a pressure roller B is pneumatically provided for pneumatically pressing the wire straightening and driving the outwardly protruding pressure ring. Corresponding to the bottom side of pressure roller B, a wire detection encoder is rotatably provided for detecting the wire. On both sides of pressure roller B, horizontal pressure rollers are pneumatically provided for pressing the wire during straightening and feeding. At the feeding end of the wire feeding fixing plate, a feeding guide roller is provided for guiding the wire feeding.

[0008] Preferably, a first cylinder is provided through the top of the inner side of the wire feeding fixing plate, and a strip-shaped mounting frame is provided horizontally at the bottom of the piston rod of the first cylinder, so that the lifting wire feeding straightening positioning roller can move up and down to straighten the wire and feed the wire.

[0009] Preferably, the lifting and straightening positioning roller is uniformly rotated inside the strip mounting frame, and a servo motor A is provided at one end of the outer side of the strip mounting frame to drive the lifting and straightening positioning roller to rotate.

[0010] Preferably, a wire straightening belt is provided between the lifting wire feeding and straightening positioning rollers, and the surface of the wire straightening belt is provided with a semi-circular wire straightening positioning groove, which can keep the wire in a horizontal and straight state during the straightening and feeding process and avoid bending in the middle of the wire feeding.

[0011] Preferably, one end of the rotating shaft of the lifting wire feeding straightening positioning roller extends through to the outer side of the strip mounting frame, and the extended rotating shaft of the lifting wire feeding straightening positioning roller is connected to the servo motor A for transmission, so that the lifting wire feeding straightening positioning roller drives the wire feeding straightening belt to straighten and feed the wire.

[0012] Preferably, the inner bottom of the wire feeding fixing plate is provided with a mounting frame, and the fixed wire feeding straightening positioning rollers are evenly arranged inside the mounting frame and are also driven by a wire feeding straightening belt. The wire feeding straightening belt is also provided with a wire feeding straightening positioning groove. One end of the mounting frame is provided with a servo motor B that is driven by a rotating shaft at one end of the fixed wire feeding straightening positioning rollers, which drives the fixed wire feeding straightening positioning rollers to rotate and drive the straightening belt to straighten and feed the wire.

[0013] Preferably, the upper end of the frame of the pressure roller A is provided with a second cylinder, the upper end of the frame of the pressure roller B is provided with a third cylinder, and the upper end of the frame of the horizontal pressure roller is provided with a fourth cylinder. The second cylinder, the third cylinder and the fourth cylinder are sequentially fixed through the top of the wire feeding fixing plate to realize the bending and straightening work of wires of different sizes.

[0014] Preferably, one end of the rotating shaft of the feed guide roller is fitted with a square plate through a bearing, and the square plate is flush with and fixed to the feed end of the wire feeding fixing plate to achieve the guiding function of straightening the wire feed.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows: The wire straightening and feeding mechanism for plug assembly, through the combination of a lifting and lowering wire straightening positioning roller, a fixed wire straightening positioning roller, a first cylinder, a wire straightening belt, a wire straightening positioning groove, servo motor A, and servo motor B on the wire feeding fixing plate, positions the wire in the wire straightening positioning groove of the wire straightening belt after it is fed by the pressure roller. The first cylinder causes the lifting and lowering wire straightening positioning roller to press the wire straightening belt against the end of the wire, and the wire straightening positioning groove positions and presses the end of the wire. Simultaneously, servo motors A and B drive the wire straightening belt through the lifting and lowering wire straightening positioning roller and the fixed wire straightening positioning roller, thus feeding the wire. Furthermore, the combination of the wire straightening positioning groove allows for longer length positioning, straightening, and feeding, keeping the wire in a horizontal straight state, thereby preventing the problem of the wire constantly swinging due to gaps during wire straightening, which could lead to the breakage of the battery core.

[0016] The wire is pressed and fed using a combination of pressure roller A, pressure roller B, horizontal pressure roller, second cylinder, third cylinder, fourth cylinder, and wire detection encoder. During the pressing and feeding of different wires, the second, third, and fourth cylinders are used to pneumatically adjust the pressure rollers A, B, and horizontal pressure rollers to a suitable pressing height according to the different wire diameters. This prevents excessive friction between the wire and pressure rollers A, B, and horizontal pressure rollers due to excessive pressing force, which could cause friction damage to the wire surface. The wire maintains a suitable pressing force during horizontal pressing and feeding, thus ensuring the quality of the wire during the pressing process. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a wire straightening and feeding mechanism for plug assembly, comprising:

[0024] The wire feeding fixing plate 1 is a frame-shaped plate with an opening on one side. Its upper end is pneumatically telescopically equipped with a lifting wire feeding and straightening positioning roller 2 for pressing, straightening, and feeding the wire. This roller presses and straightens the wire horizontally, ensuring even pressing and feeding of the antenna. Correspondingly, the lower side of the lifting wire feeding and straightening positioning roller 2 is equipped with a fixed wire feeding and straightening positioning roller 3 for supporting and positioning the wire during straightening and feeding, keeping the wire horizontal. The feed end of the lifting wire feeding and straightening positioning roller 2 is pneumatically equipped with a pressure roller A4 for pressing the wire downwards during feeding, maintaining a horizontal and straight state. This allows adjustment of the downward pressure force during wire pressing, preventing inertial swaying and bending. One side of the pressure roller A4 is pneumatically equipped with a pressure roller B5 for pneumatically pressing and straightening the wire and driving an outwardly protruding pressure ring. This allows the wire detection encoder 6 to cooperate in wire pressing positioning and wire detection.

[0025] The pressure roller B5 is equipped with a wire detection encoder 6 on its bottom side for detecting the wire. The design of the wire detection encoder 6 can include different structures; a roller structure is a common choice, but not the only one. The encoder's function is to provide precise displacement, speed, and direction information by sensing the movement of the wire. In this process, the roller structure encoder can obtain the displacement data of the wire by contacting the wire and rotating with the wire's movement. The pressure roller B5 is pneumatically equipped with horizontal pressure rollers 7 on both sides for feeding and straightening the wire. These rollers can adjust the pressure and depth of the wire to prevent downward bending caused by excessive pressure. The feeding end of the wire feeding fixing plate 1 is equipped with a feeding guide roller 8 for guiding the wire during feeding, preventing displacement during feeding and damage during the pressure process.

[0026] The top inner side of the wire feeding fixing plate 1 is provided with a first cylinder 9. The bottom end of the piston rod of the first cylinder 9 is provided with a strip-shaped mounting frame 10. The lifting wire feeding straightening positioning roller 2 is uniformly rotated and arranged inside the strip-shaped mounting frame 10, which can make the wire appear on the horizontal straightening plane during the straightening process, avoiding the phenomenon of vertical bending caused by large gaps between the rollers. A servo motor A11 is provided at one end of the outer side of the strip-shaped mounting frame 10, which drives the lifting wire feeding straightening positioning roller 2 to rotate. A wire feeding straightening belt 12 is provided between the lifting wire feeding straightening positioning rollers 2, which can make the longer length of the wire appear on the straightening horizontal plane, reducing the phenomenon of swinging and bending during transportation. The surface of the wire feeding straightening belt 12 is provided with a wire feeding straightening positioning groove 13 with a semi-circular structure, which realizes the function of centering the wire during the wire feeding straightening. One end of the rotating shaft of the lifting wire feeding straightening positioning roller 2 extends through to the outer side of the strip-shaped mounting frame 10, and the rotating shaft of the extension of the lifting wire feeding straightening positioning roller 2 is connected to the servo motor A11 for transmission.

[0027] The inner bottom of the wire feeding fixing plate 1 is provided with a mounting frame 14, and the fixed wire feeding straightening positioning rollers 3 are evenly arranged inside the mounting frame 14 and are also driven by a wire feeding straightening belt 12 to realize the straight support and feeding of the wire. The wire feeding straightening belt 12 is also provided with a wire feeding straightening positioning groove 13 to ensure the stability of the wire straightening and feeding position. One end of the mounting frame 14 is provided with a servo motor B15 that is driven by a shaft at one end of the fixed wire feeding straightening positioning rollers 3 to drive the fixed wire feeding straightening positioning rollers 3 to rotate. The upper end of the frame of the pressure roller A4 is provided with a second cylinder 16 to press the end of the wire to protect it. The frame of the wire pressing roller B5 is equipped with a third cylinder 17, which allows the wire pressing roller B5 to adjust and press the wire according to different diameter wires. The frame of the horizontal wire pressing roller 7 is equipped with a fourth cylinder 18. The second cylinder 16, the third cylinder 17 and the fourth cylinder 18 are sequentially fixed to the top of the wire feeding fixing plate 1. The cylinders set the extension and retraction distance data of the hydraulic system between wire feeding operations so that the cylinders can automatically adjust the pressing when encountering wires of different diameters. One end of the rotating shaft of the feeding guide roller 8 is fitted with a square plate 19 through a bearing, and the square plate 19 is flush with and fixed to the feeding end of the wire feeding fixing plate 1.

[0028] Specifically, during use, the wire is fed through the feed guide roller 8 to guide and keep it in its initial position, preventing damage to the wire sheath caused by improper positioning. The wire then passes through the wire detection encoder 6, which detects changes in wire length and position, ensuring the wire is of the appropriate length for use in the plug. Next, the third cylinder 17 pushes the pressure roller B5 downwards, causing its outer convex ring to press against the wire groove of the wire detection encoder 6, clamping and positioning the wire. This facilitates the detection of wire length and displacement, while maintaining the wire in the same position. At this point, the fourth cylinder 18 pushes the horizontal pressure rollers 7 on both sides of the pressure roller B5 downwards to press down on the input and output wires, keeping them horizontal and preventing wire damage during transport. The phenomenon of up-and-down swinging occurs during the process. After the wire is conveyed by the pressure roller, it is positioned in the wire straightening positioning groove 13 of the wire straightening belt 12 on the fixed wire straightening positioning roller 3. The first cylinder 9 moves the lifting wire straightening positioning roller 2 down so that the wire straightening belt 12 presses against the end of the wire. The wire straightening positioning groove 13 is used to position and press the end of the wire. At the same time, the servo motor A11 and servo motor B15 drive the lifting wire straightening positioning roller 2 and the fixed wire straightening positioning roller 3 to drive the wire straightening belt 12 to perform transmission, which can perform the wire feeding function. At the same time, the combination of the wire straightening positioning groove 13 can be used to straighten and feed the wire for a longer length, keeping the wire in a horizontal straight state. This prevents the problem of the wire swinging continuously due to gaps during wire straightening, which could cause the battery core to break.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
