[0031] It should be further understood that the term "and / or" used in the present description and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0032] Combine Figure 1 As shown, an embodiment of the present invention provides a device for eliminating twisting of wire rotation, comprising two support drive mechanisms and two clamping and rotating mechanisms 2 installed on the same side. The two clamping and rotating mechanisms 2 are respectively installed on the two support drive mechanisms. The support drive mechanism includes a drive assembly 1. The clamping and rotating mechanisms 2 are connected to the drive assembly 1. The drive assembly 1 is used to drive the clamping and rotating mechanisms 2 to rotate according to a set direction, speed and number of revolutions.

[0033] The two driving assemblies 1 drive the two clamping rotating mechanisms 2 to rotate in opposite directions.

[0034] In this embodiment, the device for eliminating twisting of wire rotation is two rotating devices with the same structure but opposite rotation directions, and the two rotating devices are placed side by side in the same direction; specifically, taking the structure of one of the rotating devices as an example, the rotating device includes a supporting drive mechanism and a clamping rotating mechanism 2, and the clamping rotating mechanism 2 is installed at the output end of the supporting drive mechanism so that the supporting drive mechanism drives the clamping rotating mechanism 2 to rotate, and the clamping end of the clamping rotating mechanism 2 can clamp the wire 4.

[0035] In some methods for achieving the rotation of the clamped wire 4, the supporting drive mechanism includes a drive component 1, and the clamping rotation mechanism 2 is connected to the output end of the drive component 1, and the drive component 1 is used to drive the clamping rotation mechanism 2 to rotate; more specifically, the rotation direction, speed and number of turns of the drive component 1 are preset before working, wherein the rotation speed and number of turns of the two drive components 1 are the same, but the rotation directions are opposite; further, the two clamping rotation mechanisms 2 clamp the two ends of the wire 4, and then the two drive components 1 drive their respective corresponding clamping rotation mechanisms 2, thereby rotating the two ends of the wire 4 in opposite directions to each other, so as to reduce the internal torque of the wire 4 (the irregular torque accumulated by the wire 4 in the previous multiple workstations), so that when the wire 4 is crimped to the terminals at both ends of the wire 4, the wire 4 with the crimped terminals will not be deflected relative to the terminals due to the internal torque of the wire 4, which is beneficial for the wire 4 with the crimped terminals to maintain high-precision plugging in the downstream plug-in shell station.

[0036] In this embodiment, two rotating devices with the same structure are used to ensure that the two clamping rotating mechanisms 2 are installed on the same side of their respective supporting drive mechanisms. During the rotation process, the wires will not be slowly tightened, thereby avoiding damage to the internal conductor of the wires 4.

[0037] In one embodiment, the clamping rotation mechanism 2 includes a rotating shaft 21, a cylinder 22 and a clamping jaw 23. One end of the rotating shaft 21 is connected to the driving assembly 1, and the cylinder 22 is connected to the other end of the rotating shaft 21. The clamping jaw 23 is arranged on the cylinder 22, and the cylinder 22 is used to drive the clamping jaw 23 to open and close.

[0038] In this embodiment, the driving assembly 1 drives the rotating shaft 21 to rotate, so that the rotating shaft 21 can drive the cylinder 22 and the clamping jaw 23 to rotate synchronously.

[0039] In some methods of transporting the wire 4 to the clamping jaws 23, a wire transporting assembly (not shown in the figure) is used to transport the two ends of the wire 4 to the clamping positions of the two clamping rotating mechanisms 2 respectively, and then the cylinder 22 drives the clamping jaws 23 to close and clamp the two ends of the wire 4, and then the two driving assemblies 1 start to drive their respective clamping rotating mechanisms 2 to rotate in opposite directions for a set number of turns to reduce the torque accumulated inside the wire 4. After the rotation is completed, the cylinder 22 drives the clamping jaws 23 to release the wire 4, and then the wire transporting assembly (not shown in the figure) pulls the wire 4 out and transports it to the next workstation. If the next wire 4 needs to be processed, the wire transporting assembly (not shown in the figure) continues to transport the wire 4 to the clamping position of the clamping rotating mechanism 2, and the above steps can be repeated.

[0040] like Figure 2 As shown, in a more specific embodiment, a vent hole 211 is axially opened in the rotating shaft 21, and a joint assembly 3 is provided at one end of the rotating shaft 21. The joint assembly 3 includes a rotary joint 31 and an L-shaped quick-connect joint 32. The rotary joint 31 includes a rotor end 311 and a stator end 312. The rotor end 311 of the rotary joint 31 is threadedly connected to one end of the rotating shaft 21, and the stator end 312 of the rotary joint 31 is threadedly connected to one end of the L-shaped quick-connect joint 32. The other end of the L-shaped quick-connect joint 32 is used to connect to the equipment air source (not shown in the figure); the vent hole 211 at the other end of the rotating shaft 21 is connected to the air path of the cylinder 22.

[0041] In this embodiment, compared with the prior art method of using an external air pipe to supply air, which makes the air pipe easy to be entangled during the rotation of the wire rotation and twisting elimination device, the present application adopts an internal air supply method to prevent the air pipe from being entangled during the rotation of the wire rotation and twisting elimination device; specifically, the cylinder 22 is a single-acting normally open finger cylinder, and the rotating shaft 21 can realize the connection between the air path of the cylinder 22 and the air source of the equipment through the provided air vent 211, so that the cylinder 22 can take in air from the inside of the rotating shaft 21, and the air pipe can be avoided from being entangled in the process of the rotating shaft 21 driving the cylinder 22 to rotate.

[0042] In one embodiment, the driving assembly 1 includes a motor 11 and a synchronous belt assembly 12 , one end of the synchronous belt assembly 12 is coaxially connected to the output shaft of the motor 11 , and the other end of the synchronous belt assembly 12 is coaxially connected to the rotating shaft 21 .

[0043] In this embodiment, the synchronous belt assembly 12 is equivalent to an intermediate component for transmitting rotational motion between the motor 11 and the rotating shaft 21. By setting the synchronous belt assembly 12, the torque of the motor 11 is transmitted to the rotating shaft 21, so that the rotating shaft 21 drives the cylinder 22 and the clamp 23 to rotate synchronously.

[0044] In a more specific embodiment, the synchronous belt assembly 12 includes a synchronous belt 123, a first synchronous wheel 121 and a second synchronous wheel 122, the first synchronous wheel 121 is coaxially connected to the output shaft of the motor 11, the second synchronous wheel 122 is sleeved on the rotating shaft 21, and the synchronous belt 123 is sleeved on the first synchronous wheel 121 and the second synchronous wheel 122.

[0045] In this embodiment, the motor 11 drives the first synchronous wheel 121 to rotate, the synchronous belt 123 drives the second synchronous wheel 122 to rotate, and then the second synchronous wheel 122 drives the rotating shaft 21 to rotate, so that the motor 11 drives the rotation of the clamping rotating mechanism 2.

[0046] It can be understood that the motors 11 of the two drive assemblies 1 are set to rotate clockwise, and the other is set to rotate counterclockwise, so that the two motors 11 drive their respective clamping rotating mechanisms 2 to rotate in opposite directions, wherein the rotation speed and number of rotations of the clamping rotating mechanism 2 are also set by the motor 11.

[0047] like Figure 3 As shown, in one embodiment, the supporting drive mechanism also includes a supporting shell 5, the top of the supporting shell 5 extends toward the front side, the motor 11 is installed at the bottom of the supporting shell 5, the clamping rotating mechanism 2 is installed at the top of the supporting shell 5, and the cylinder 22 of the clamping rotating mechanism 2 protrudes toward the top front side of the supporting shell 5.

[0048] In this embodiment, the support shell 5 includes a first support shell 51, a second support shell 52 and a third support shell 53. The first support shell 51, the second support shell 52 and the third support shell 53 are connected in sequence toward the front. The motor 11 is installed at the bottom of the second support shell 52, and the clamping rotation mechanism 2 is installed at the top of the second support shell 52. Specifically, the rotating shaft 21 is installed at the inner top of the second support shell 52, and the output ends of the cylinder 22 and the clamp 23 are installed in the third support shell 53 toward the front; the first supporting shell 51 is installed with a first synchronous wheel 121, a synchronous belt 123 and a second synchronous wheel 122, one end of the joint assembly 3 is installed on the rotating shaft 21, and the other end of the joint assembly 3 is exposed outside the first supporting shell 51.

[0049] It is understood that the front direction as described above is Figure 1 The cylinder 22 is shown facing in the direction of the clamping jaws 23 .

[0050] like Figure 2 and Figure 3 As shown, in one embodiment, at least two bearings 212 are provided in the top of the supporting shell 5 , and the rotating shaft 21 is installed in the bearings 212 .

[0051] In this embodiment, the bearing 212 is installed in the second support shell 52 , and the rotating shaft 21 is rotatably installed in the bearing 212 . The bearing 212 limits the axial movement of the rotating shaft 21 , thereby achieving stable rotation of the rotating shaft 21 .

[0052] It is understandable that multiple bearings 212 can be installed, and this is not limited here.

[0053] like Figure 4 As shown, in one embodiment, an optical coupler detector 521 is provided on the support shell 5, and an induction plate 213 for triggering the optical coupler detector 521 is provided on the rotating shaft 21. The clamping rotating mechanism 2 also includes a locking nut 214, which axially fastens the induction plate 213 and the second synchronous wheel 122 to the rotating shaft 21.

[0054] In this embodiment, the optical coupler detector 521 is installed on the back side of the second supporting shell 52 and is located inside the first supporting shell 51. A sensing piece 213 is installed on the rotating shaft 21. The sensing piece 213 corresponds to the sensing port of the optical coupler detector 521. Therefore, when the rotating shaft 21 rotates, the sensing piece 213 is driven to rotate, so that the rotating shaft 21 rotates one circle, and the sensing piece 213 can trigger the optical coupler detector 521 once; the setting of the sensing piece 213 and the optical coupler detector 521 is mainly used to detect the rotation speed and number of rotations of the clamping rotating mechanism 2, so as to reasonably control the operation of the rotating clamping mechanism.

[0055] like Figure 1 As shown, in one embodiment, the clamping jaw 23 includes a first clamping jaw 231 and a second clamping jaw 232 that slide relative to each other, and the cylinder 22 is used to drive the first clamping jaw 231 and the second clamping jaw 232 to slide relative to or back to back.

[0056] In this embodiment, the cylinder 22 is a single-acting normally open finger cylinder, and the first jaw 231 and the second jaw 232 are installed on the cylinder 22 in a relatively sliding manner. When the connector assembly 3 is connected to the equipment air source and ventilated, the cylinder 22 can drive the first jaw 231 and the second jaw 232 to slide relative to each other, so that the first jaw 231 and the second jaw 232 can clamp the wire 4; when the air supply is stopped, the spring inside the cylinder 22 resets and drives the first jaw 231 and the second jaw 232 to slide back to back, so that the first jaw 231 and the second jaw 232 release the wire 4.

[0057] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
