The actions are parallel, which greatly shortens the processing time of a single product.

[0016] (3) The first, second and third picking parts are designed to specifically clamp the winding part, the plug part and the tail of the power cord, respectively.

[0022] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0025] In the description of this embodiment, the terms "upper," "lower," "left," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0026] The first direction is the X-axis direction, and the third direction is the Z-axis direction. The first direction and the third direction are perpendicular.

[0027] like Figures 1 to 5 As shown, this embodiment provides a power cord feeding and twisting device, which is used to automatically complete the entire process of feeding, transferring, twisting and bundling with wire, and finally discharging the power cord on the power cord production line.

[0028] The power cord picking and twisting device includes a picking and twisting lateral movement module 1. In this embodiment, the picking and twisting lateral movement module 1 preferably adopts a precision linear module driven by a servo motor to ensure accurate and efficient movement. Its direction of movement is defined as a first direction (i.e., Figure 1 (The X-axis direction is shown in the diagram). A material picking and twisting transverse moving plate 11 is provided on the sliding output end of the material picking and twisting transverse moving module 1. A material picking vertical moving module 12 and a twisting vertical moving module 13 are fixedly installed side by side on the material picking and twisting transverse moving plate 11. Among them, the material picking vertical moving module 12 is located at the end closer to the winding device, while the twisting vertical moving module 13 is located at the end closer to the wire feeding device. It should be noted that the winding device is a device for winding the power cord into a coil, and the wire feeding device is a device for conveying the iron wire to be bundled. These two devices are not innovative points of this utility model embodiment and will not be described in detail here.

[0029] The material handling vertical movement module 12 and the twisting vertical movement module 13 are preferably precision linear modules driven by servo motors, and their movement direction is defined as the third direction (i.e., Figure 1 The Z-axis direction shown is substantially perpendicular to the first direction.

[0030] At the output end of the vertical moving material handling module 12, a complex material handling assembly 2 is installed. This material handling assembly 2 consists of three complementary parts that work together to ensure stability and reliability when handling coiled power cables.

[0031] like Figure 2 and 3 As shown, the first picking section 21 has two or three sets; in this embodiment, two sets are provided to grip the most tightly wound main body part of the power cord. Each set of the first picking section 21 includes a first picking cylinder 211. The output end of the cylinder is rotatably connected to a pair of opposing first grippers 212 via a linkage mechanism. The upper middle part of the first grippers 212 is also connected to the bottom of the cylinder body of the first picking cylinder 211 via a rotating shaft, forming a lever structure. When the piston rod of the first picking cylinder 2114 extends or retracts, it drives the bottom of the pair of first grippers 212 to open or close, thus firmly gripping the middle part of the power cord coil like a "hand".

[0032] like Figure 2 As shown, the second gripping section 22 is specifically designed to grip the plug portion of the power cord. It includes a second finger cylinder 221, with a pair of second grippers 222 fixed to each of its two output ends. The inner shape of these grippers 222 simultaneously forms a second plug clamping groove 223 and a second wire clamping groove 224. The shape of the second plug clamping groove 223 matches the shape of the power cord plug, allowing it to accommodate and clamp the plug; the second wire clamping groove 224 clamps the wire at the rear end of the plug. This structure ensures a more secure grip and prevents damage to the plug.

[0033] like Figure 2 As shown, the third feeding section 23 is used to grip the tail end of the power cord. It includes a third finger cylinder 231, with a pair of third grippers 232 fixed to its two output ends. The inner side of the third grippers 232 forms a third wire clamping groove 233 for directly clamping the tail end of the power cord.

[0034] like Figure 1 , 4 As shown in Figure 5, a twisting assembly 3 is installed at the output end of the twisting vertical movement module 13. In this embodiment, the assembly includes two sets of side-by-side twisting sections 31 to simultaneously perform twisting operations on both ends of the power cable harness. Twisting refers to the process of twisting the U-shaped iron wire after the wire feeding device has finished feeding the iron wire, so that the coiled power cable is tightly bound by the iron wire. Each twisting section 31 includes a twisting drive module 311, which is composed of a first twisting drive module 3111 and a second twisting drive module 3112.

[0035] like Figure 4 and5 As shown, the first twisted wire drive module 3111 provides the main rotational power. It includes a first twisted wire mounting plate 31111, on which a first twisted wire drive motor 31112 is mounted. A first twisted wire drive pulley 31113 is mounted on the output shaft of the first twisted wire drive motor 31112. A first twisted wire shaft 31115 is also rotatably mounted on the first twisted wire mounting plate 31111 via bearings. A first twisted wire follower pulley 31114 is mounted on the top of the first twisted wire shaft 31115, and its bottom is connected to the second twisted wire drive module 3112. A first twisted wire belt (not shown) is fitted between the first twisted wire drive pulley 31113 and the first twisted wire follower pulley 31114. The first twisted wire drive motor 31112 drives the entire first twisted wire shaft 31115 and the second twisted wire drive module 3112 at its bottom to rotate together via belt drive.

[0036] The first twisting shaft 31115 is configured as a hollow structure that extends vertically. A second twisting drive module 3112 is installed at the bottom of the first twisting shaft 31115 and is a second twisting cylinder 31121. The air intake channel of the second twisting cylinder 31121 is connected to the interior of the hollow first twisting shaft 31115, forming a rotating air path, perfectly solving the problem of air pipe entanglement on rotating components.

[0037] like Figure 4 and 5 As shown, the twisting clamp 32 is used to directly perform the action of clamping and twisting the wire. A pair of second twisting mounting plates 31122 are fixed to both sides of the bottom of the second twisting cylinder 31121, and a pair of second twisting support rods 31123 are fixed between the two twisting mounting plates. The piston rod of the second twisting cylinder 31121 is hinged to both sides by second twisting linkage plates 31124. The other end of the second twisting linkage plate 31124 is hinged to the twisting clamp 32, and the middle part of the twisting clamp 32 is also hinged to the second twisting support rods 31123. When the piston rod of the second twisting cylinder 31121 moves, the lever action of the second twisting linkage plate 31124 drives the two twisting clamps 32 to open or close with their hinge points with the support rods as the center.

[0038] The following describes the working process of the power cord feeding and twisting device provided by this utility model: The material taking, twisting, and transverse movement module 1 drives the entire mechanism to the "material taking position" near the winding device.

[0039] Material handling and twisting occur in parallel. The material handling vertical movement module 12 drives the material handling assembly 2 to descend, while the first material handling section 21, the second material handling section 22, and the third material handling section 23 operate simultaneously, clamping the middle, plug end, and tail end of the power cord already wound on the winding device, respectively. Then, the material handling vertical movement module 12 rises. At the same time, a bundle of previously transferred power cords is placed on the "twisting station" of the wire feeding device. The twisting vertical movement module 13 drives the twisting assembly 3 to descend, aligning the middle of the two twisting clamps 32 with the wire. The second twisting cylinder 31121 actuates, driving the twisting clamps 32 to close and clamp both ends of the wire. Subsequently, the first twisting drive motor 31112 starts, rotating the entire twisting head several times to tighten the wire.

[0040] Lateral movement and material discharge preparation: The material picking and twisting lateral movement module 1 drives the entire mechanism to move along the first direction, from the "material picking position" to the "material discharging and twisting position" near the wire feeding device. During this movement, the twisting assembly 3, which has just completed twisting, keeps its twisting clamp 32 in a closed state, "lifting" the bundled power cord from the clamp of the wire feeding device, preparing for subsequent material discharge.

[0041] The feeding and discharging processes proceed in parallel. Upon reaching the "feeding and twisting position," the vertical moving module 12 descends, and the picking component 2 releases, precisely placing the newly picked, unbundled power cord into the idle position of the feeding device. Simultaneously, after the twisting component 3 removes the previous bundle of power cords, the twisting clamp 32 opens, and the already bundled power cords automatically fall into the discharge area due to gravity or the action of the conveyor belt below, completing the discharge process. Subsequently, the picking and twisting horizontal moving module 1 drives the entire device back to the "picking position," beginning the next work cycle.

[0042] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
