Description

Technical Field

[0001] This utility model relates to the technical field of coil splitting equipment, and in particular to a coil splitting and twisting device. Background Technology

[0002] After the coil is wound, the next processing step is to put the wound coil into the corresponding shell and align the copper wires with the pins of the shell. However, the freshly wound coils are of different lengths and the wires are intertwined and messy, so they cannot be put directly into the shell. At the same time, some copper wires have two wires corresponding to the same pin, so the two copper wires need to be twisted into one. Therefore, it is particularly critical and important to separate and twist multiple sets of copper wires in advance.

[0003] Currently, these two processes are generally completed manually. This results in low production efficiency, and because the coils are very small and the precision required by manual labor is not high, it can easily lead to poor product quality and a low yield of high-quality products.

[0004] CN 114496416 B discloses a coil stranding device and method for coils to be inserted into a housing, which can effectively solve the above-mentioned problems. During the stranding process, the length of the copper wire will shorten, but the stranding clamp in the device is fixed on a support frame. This means that the stranding clamp can only be relatively fixed in a single position, which makes the copper wire prone to breakage during stranding, reducing the yield of high-quality products. Utility Model Content

[0005] Therefore, it is necessary to address the issue that the stranding clamp of the current coil stranding device is fixed on a support frame, which means that the stranding clamp can only be fixed in a single position. This can easily cause the copper wire to break during stranding, reducing the yield of high-quality products. Therefore, a coil stranding device should be provided.

[0006] A coil stranding device, comprising:

[0007] Wire coil clamping mechanism;

[0008] A wire clamping mechanism, wherein there are multiple wire clamping mechanisms arranged circumferentially around the wire package clamping mechanism;

[0012] The above-mentioned coil stranding device has the stranding clamp assembly mounted on the transverse driver. In this way, during stranding, the stranding clamp assembly can move toward the coil clamping mechanism, thus preventing the copper wire from being broken during stranding, effectively improving production quality and increasing oil yield.

[0018] In one embodiment, the stranded wire clamp assembly includes a mounting sleeve, a stranded wire clamp, a top rod, a top block, and an elastic element. The mounting sleeve is rotatably mounted on the mounting base. The stranded wire clamp is disposed at one end of the mounting sleeve. The top rod passes through the mounting sleeve.

The vertical driver 51 allows the stranding clamp 552 to be adjusted according to the height of the copper wire to be stranded, thus improving the adaptability of the coil stranding device 100.

[0048] Please see Figure 5 The stranded wire clamp assembly 55 includes a mounting sleeve 551, a stranded wire clamp 552, a top block (not shown), a top rod 553, and an elastic element 554. The mounting sleeve 551 is rotatably mounted on the mounting base 54. The stranded wire clamp 552 is located at one end of the mounting sleeve 551. The top rod 553 passes through the mounting sleeve 551. One end of the top rod 553 is fixedly connected to the top block, and the other end of the top rod 553 is provided with a limit cap.

[0051] Please see Figure 1 The dividing gripper 60 consists of two parallel-arranged cylinder grippers. The handling robot includes a robot body, an X-axis motion driver, a Z-axis motion driver, and a Y-axis motion driver. The robot body moves along the X-axis direction under the drive of the X-axis motion driver, moves along the Z-axis direction under the drive of the Z-axis motion driver, and moves along the Y-axis direction under the drive of the Y-axis motion driver.

[0052] Please see Figure 1 The coil stranding device 100 further includes a base plate 70 and a front and rear movement driver 80. The coil clamping mechanism 10, the wire clamping mechanism, the stranding mechanism 50 and the stranding claw 60 are all disposed on the base plate 70. The base plate 70 moves along the Y-axis direction under the drive of the front and rear movement driver 80.

[0053] In this embodiment, the working process of the coil stranding device 100 is as follows: During operation, the robot body is driven by the X-axis movement driver, Z-axis movement driver and Y-axis movement driver to clamp the coil and place the coil between the fixing block 14 and the clamping block 15. The clamping driver 16 drives the clamping block 15 to move upward to clamp the coil.

[0054] During the distribution process, the robotic arm holds all the copper wires and moves along the Y-axis towards the wire-separating jaw 60 under the drive of the Y-axis movement driver until the robotic arm is located at the end of the wire-separating jaw 60 away from the coil clamping mechanism 10. The front cylinder jaw of the wire-separating jaw 60 holds the copper wires, and the robotic arm continues to move until the end of the longest copper wire. The robotic arm then disengages the longest copper wire from the front cylinder jaw of the wire-separating jaw 60 and sends the longest copper wire to the corresponding wire clamping mechanism for fixation. At the same time, the rear cylinder jaw of the wire-separating jaw 60 holds the remaining copper wires. This process is repeated until the last copper wire is distributed.

[0055] During stranding, the piston rod of the clamping driver 57 pushes the top rod 553 outward, and the top block pushes the stranding clamp 552 to open the stranding clamp 552. The robot body places the copper wire to be stranded into the stranding clamp 552, the clamping driver 57 resets, and under the action of the elastic element 554, the top rod 553 resets, the stranding clamp 552 closes and clamps the copper wire to be stranded, and the rotation driver 56 drives the stranding clamp 552 to rotate to realize the stranding process. During the stranding process, the transverse driver 52 drives the stranding clamp 552 to move toward the coil clamping mechanism 10, which can avoid the phenomenon that the copper wire is easily pulled off during stranding, thereby effectively improving production quality and increasing the yield of high-quality products.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
