Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

As used in the specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

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

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

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

[0034] In this embodiment, the wire rotation and twist elimination device 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 driving mechanism and a clamping rotating mechanism 2, and the clamping rotating mechanism 2 is installed at the output end of the supporting driving mechanism so that the supporting driving 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 driving mechanism includes a driving component 1, and the clamping rotating mechanism 2 is connected to the output end of the driving component 1, and the driving component 1 is used to drive the clamping rotating mechanism 2 to rotate; more specifically, the driving component 1 presets the rotation direction, speed and number of turns before working, wherein the rotation speed and number of turns of the two driving components 1 are consistent, but the rotation directions are opposite; further, the two clamping rotating mechanisms 2 clamp the two ends of the wire 4, and then the two driving components 1 drive their respective corresponding clamping rotating 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 two ends of the wire 4, the wire 4 with the crimped terminal will not be deflected relative to the terminal due to the internal torque of the wire 4, which is beneficial for the wire 4 with the crimped terminal 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 driving mechanisms. The wires will not be slowly tightened during the rotation process, thereby avoiding damage to the internal conductor of the wire 4.

[0037] In one embodiment, the clamping rotation mechanism 2 includes a rotating shaft 21, a cylinder 22 and a clamp 23, one end of the rotating shaft 21 is connected to the driving assembly 1, the cylinder 22 is connected to the other end of the rotating shaft 21, the clamp 23 is arranged on the cylinder 22, and the cylinder 22 is used to drive the clamp 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 begin to drive their respective clamping rotating mechanisms 2 to rotate in opposite directions for a set number of circles 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 are 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 swivel joint 31 and an L-shaped quick-connect joint 32. The swivel joint 31 includes a rotor end 311 and a stator end 312. The rotor end 311 of the swivel joint 31 is threadedly connected to one end of the rotating shaft 21, and the stator end 312 of the swivel 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 set 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 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 clamping rotating mechanism 2 to rotate.

[0046] It can be understood that, one motor 11 of the two driving assemblies 1 is 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 oppositely to each other, 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 driving mechanism also includes a supporting shell 5, the top of the supporting shell 5 is extended 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, and the first support shell 51, the second support shell 52 and the third support shell 53 are connected in sequence toward the front side, 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 side; the first synchronous wheel 121, the synchronous belt 123 and the second synchronous wheel 122 are installed in the first support shell 51, 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 support shell 51.

[0049] It can be 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 disposed 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, a photocoupler detector 521 is provided on the support shell 5, and a sensing plate 213 for triggering the photocoupler detector 521 is provided on the rotating shaft 21. The clamping rotating mechanism 2 also includes a locking nut 214, which axially fastens the sensing plate 213 and the second synchronous wheel 122 on 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 sheet 213 is installed on the rotating shaft 21. The sensing sheet 213 corresponds to the sensing port of the optical coupler detector 521. When the rotating shaft 21 rotates, the sensing sheet 213 is driven to rotate. When the rotating shaft 21 rotates one circle, the sensing sheet 213 can trigger the optical coupler detector 521 once. The setting of the sensing sheet 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 is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
