Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0046] This embodiment provides a wire straightening device. Refer to Figures 1 to 6 As shown, the wire straightening device includes a first straightening member 1, a second straightening member 2, a first driving member 31 and a second driving member 32. Among them, the first straightening member 1 is provided with a straightening groove 11 for the wire 7 to pass through along the first direction; the second straightening member 2 is arranged above the first straightening member 1 along the second direction. One end of the second straightening member 2 facing the straightening groove 11 is provided with a telescopic groove 211. A straightening head 21 is slidably arranged in the telescopic groove 211. An elastic member 22 is arranged between the first end of the straightening head 21 placed in the telescopic groove 211 and the bottom of the telescopic groove 211. The second end of the straightening head 21 is placed outside the telescopic groove 211; the first driving member 31 is used to drive the straightening head 21 to be inserted into the straightening groove 11 and press against the wire 7 in the straightening groove 11; the second driving member 32 is used to drive the straightening head 21 and the straightening groove 11 to move relative to the wire 7 along the first direction to straighten the wire 7.

[0047] In this embodiment, for the specific directions of the first direction and the second direction, refer to Figure 1 As shown, the first direction can be a horizontal direction, and the second direction can be a vertical direction.

[0048] In this embodiment, the second straightening member 2 is located above the first straightening member 1 along the second direction. The first straightening member 1 is provided with a straightening groove 11 for the wire 7 to pass through along the first direction. One end of the second straightening member 2 facing the first straightening member 1 is correspondingly provided with a straightening head 21. The straightening head 21 is telescopically arranged in the telescopic groove 211. An elastic member 22 is arranged between the first end of the straightening head 21 placed in the telescopic groove 211 and the bottom of the telescopic groove 211. The second end of the straightening head 21 is placed outside the telescopic groove 211. When carrying out the wire straightening work, the wire 7 passes through the straightening groove 11 along the first direction. Subsequently, the first driving member 31 drives the second straightening member 2 to approach the first straightening member 1. The second end of the straightening head 21 extends into the straightening groove 11 and jointly holds the wire 7 with the straightening groove 11. Subsequently, the wire 7 remains stationary, and the second driving member 32 works to drive the first straightening member 1 and the second straightening member 2 to move along the first direction, so as to drive the straightening head 21 and the straightening groove 11 to move along the first direction to straighten the wire 7. The arrangement of the elastic member 22 provides elastic buffering for the straightening head 21 on the one hand, preventing the wire 7 from being damaged and broken due to hard contact with the wire 7, and ensuring the reliable and stable straightening work; on the other hand, it can also make the distance between the straightening head 21 and the wire groove further adjustable to adapt to wires 7 of different sizes. This device can carry out fast and reliable automatic straightening work on the wire 7, liberate manpower, ensure the straightening effect, and avoid damaging the wire 7.

[0049] The wire straightening device provided in this embodiment can be applied to the core wire 71 of the magnetic ring 72 and can also be used for other types of wire structures, which will not be limited here too much.

[0050] In this embodiment, the first straightening member 1 is provided with a plug-in groove 12 along the second direction, and the second straightening member 2 is correspondingly provided with a plug-in portion 23 for inserting into the plug-in groove 12. In this embodiment, the plug-in groove 12 is opened with the second direction as the depth direction. Specifically, when the first driving member 31 works to drive the first straightening member 1 to approach the second straightening member 2, during the process, the plug-in portion 23 first inserts into the plug-in groove 12. As the plug-in portion 23 continues to insert, the first end of the straightening head 21 further extends into the straightening groove 11. The cooperation between the plug-in portion 23 and the plug-in groove 12 can provide moving guidance between the first straightening member 1 and the second straightening member 2, ensuring that the first straightening member 1 and the second straightening member 2 approach or move away from each other strictly along the second direction, and ensuring the reliable and stable overall structure.

[0051] Specifically, the first straightening member 1 includes a base portion 101 and a boss portion 102 provided on the base portion 101. The wire straightening groove 11 and the insertion groove 12 are both formed in the boss portion 102, and the wire straightening groove 11 penetrates through the boss portion 102 along the first direction. Specifically, the provision of the boss portion 102 is specifically for providing a space for forming the wire straightening groove 11 and the insertion groove 12, while the provision of the base portion 101 facilitates the connection of the first driving member 31. Specifically, the base portion 101 and the boss portion 102 are integrally formed.

[0052] Furthermore, the insertion groove 12 divides the wire straightening groove 11 into two sub-groove portions 111 spaced along the first direction. The wire straightening head 21 includes two sub-head portions 2102 spaced along the first direction. The two sub-head portions 2102 are arranged in one-to-one correspondence with the two sub-groove portions 111. The sub-head portions 2102 are for being inserted into the corresponding sub-groove portions 111 and pressing the wire 7 within the sub-groove portions 111. The insertion portion 23 is located between the two sub-head portions 2102, and the corresponding sides of the sub-head portions 2102 and the insertion portion 23 are in contact. With such an arrangement, both the two sub-head portions 2102 and the two sub-groove portions 111 can press the wire 7, and under the driving action of the second driving member 32, the wire 7 is straightened, further improving the reliability and stability of wire straightening. In addition, the contact relationship between the corresponding sides of the sub-head portions 2102 and the insertion portion 23 can also provide a certain sliding guide for the sub-head portions 2102, preventing the sliding of the sub-head portions 2102 from being displaced. Optionally, a guiding groove (not shown) for the sliding of the sub-head portions 2102 may be provided on the side surface of the insertion portion 23.

[0053] Furthermore, the insertion portion 23 is provided with an avoidance groove 231 corresponding to the wire straightening groove 11. The avoidance groove 231 is for the wire 7 to pass through. The formation of the avoidance groove 231 can ensure that the wire 7 can pass through the wire straightening groove 11 reliably and effectively. In addition, the wire straightening groove 11 and the avoidance groove 231 are for limiting the wire 7 in the second direction. Specifically, as the first straightening member 1 gradually approaches the second straightening member 2, the wire straightening groove 11 and the avoidance groove 231 approach each other. When the insertion portion 23 is inserted into the wire straightening groove 11, the wire straightening groove 11 and the avoidance groove 231 form a closed annular limiting space. At this time, the outer circumference of the wire 7 passing through the wire straightening groove 11 will be limited within this limiting space. With such an arrangement, it not only ensures that the subsequent wire straightening head 21 can reliably hold against the wire 7, but also can limit the movement range of the wire 7, preventing the wire 7 from moving randomly and ensuring the reliable progress of the subsequent straightening work.

[0054] Furthermore, the shapes of the wire straightening groove 11, the avoidance groove 231, and the first end of the wire straightening head 21 are all set to be V-shaped. When the elastic member 22 is in the natural state, the first end of the wire straightening head 21 extends out of the bottom of the avoidance groove 231. Specifically, the V-shaped bottom of the wire straightening groove 11 is arranged downward, the V-shaped bottom of the avoidance groove 231 is arranged upward, and the V-shaped end of the wire straightening head 21 is arranged downward.

[0055] Specifically, the wire aligning groove 11 has two first side groove walls 112 arranged in a V shape, the avoiding groove 231 has two second side groove walls 2311 arranged in a V shape, the first end of the wire aligning head 21 has two side head end faces 2101 arranged in a V shape, and the first side groove walls 112 and the side head end faces 2101 on the corresponding sides are arranged in parallel, that is, they have the same inclination angle. Specifically, the two first side groove walls 112 and the two second side groove walls 2311 can jointly form a diamond-shaped limiting space. The limiting space is set as a diamond shape, which can reduce the contact area with the outer circumference of the wire 7 on the one hand and can reliably and effectively limit the movement range of the wire 7 on the other hand.

[0056] In this embodiment, a plurality of wire aligning grooves 11, wire aligning heads 21, and avoiding grooves 231 are arranged at intervals along the third direction, and a plurality of wire aligning grooves 11, a plurality of wire aligning heads 21, and a plurality of avoiding grooves 231 are arranged in one-to-one correspondence. Specifically, the third direction specifically points to the reference Figure 1 As shown, the third direction can be another horizontal direction. With such a setting, the straightening work of multiple wires 7 can be carried out at one time, further improving the operation efficiency. Exemplarily, in the figure of this embodiment, the wire aligning grooves 11, the wire aligning heads 21, and the avoiding grooves 231 are arranged in one-to-one correspondence with four.

[0057] Specifically, a limiting head 212 is arranged in the telescopic groove 211, and a long hole 213 is formed in the wire aligning head 21. The long hole 213 extends along the second direction, and the limiting head 212 passes through the long hole 213. Specifically, the structural cooperation between the long hole 213 and the limiting head 212 can perform installation limiting on the wire aligning head 21, and can prevent the wire aligning head 21 from falling off the telescopic groove 211 on the premise of ensuring the reliable movement of the wire aligning head 21 along the second direction.

[0058] Specifically, a through hole 214 communicating with the telescopic groove 211 is formed in the second straightening member 2, and the limiting head 212 passes through the through hole 214 and extends into the telescopic groove 211. The limiting head 212 passes through the through hole 214 and extends into the interior of the telescopic groove 211, which is convenient for the installation and arrangement of the limiting head 212.

[0059] In this embodiment, the second straightening member 2 includes a main body portion 201 and a cover portion 202 that are buckled together. The telescopic groove 211 penetrates through the main body portion 201 along the second direction, and the elastic member 22 abuts against the cover portion 202. Specifically, the second straightening member 2 is set as a split main body portion 201 and cover portion 202, which is convenient for the assembly and replacement of components such as the wire aligning head 21 and the elastic member 22. Specifically, the main body portion 201 and the cover portion 202 can be fixedly connected through connecting members such as bolts.

[0060] Exemplarily, the side of the cover part 202 facing the main body part 201 is the bottom of the telescopic groove 211. In this embodiment, the elastic member 22 includes a spring, and the spring is arranged between the first end of the wire aligning head 21 and the bottom of the telescopic groove 211, which not only makes full use of the space inside the telescopic groove 211, but also can effectively protect the spring, avoid the spring being exposed outside, and avoid the spring accidentally coming out, ensuring the reliable operation of the wire aligning head 21.

[0061] In this embodiment, the wire straightening device further includes a base 5, the second driving member 32 is arranged on the base 5, the first driving member 31 is arranged on the second driving member 32, and both the first straightening member 1 and the second straightening member 2 are arranged on the first driving member 31. Specifically, the base 5 provides an effective fixing basis for the first straightening member 1, the second straightening member 2, the first driving member 31 and the second driving member 32. The arrangement of the base 5 connects the first straightening member 1, the second straightening member 2, the first driving member 31 and the second driving member 32 into a whole device, ensuring the reliable and stable operation of the whole device.

[0062] Exemplarily, the first driving member 31 includes an opening and closing driving cylinder, the second driving member 32 includes a first moving driving cylinder, the fixed end of the first moving driving cylinder is fixed to the base 5, the fixed end of the opening and closing driving cylinder is fixed to the telescopic end of the first moving driving cylinder, and the two movable ends of the opening and closing driving cylinder are respectively fixedly connected to the first straightening member 1 and the second straightening member 2. Specifically, the telescopic end of the first moving driving cylinder can telescopically move relative to the fixed end along the second direction, thereby driving the opening and closing driving cylinder, the first straightening member 1 and the second straightening member 2 to move along the second direction, corresponding to the straightening and smoothing action of the wire 7. The two movable ends of the opening and closing driving cylinder are respectively connected to the first straightening member 1 and the second straightening member 2, and the two movable ends of the opening and closing driving cylinder can approach or move away from each other along the first direction, thereby driving the first straightening member 1 and the second straightening member 2 to approach and move away from each other, corresponding to the insertion between the insertion part 23 and the insertion groove 12, the formation of the limiting space between the wire aligning groove 11 and the avoidance groove 231, and the abutting action of the wire aligning head 21 on the wire 7.

[0063] In some other alternative embodiments, the first driving member 31 may further include a cylinder gripper.

[0064] In some other alternative embodiments, the first driving member 31 may further include two independently arranged cylinders. The two cylinders respectively independently control the first straightening member 1 and the second straightening member 2, and the first straightening member 1 and the second straightening member 2 are respectively fixed to the telescopic ends of the two cylinders. By the telescopic movement of the telescopic ends of the two cylinders, the distance adjustment between the first straightening member 1 and the second straightening member 2 can also be achieved.

[0065] In some other alternative embodiments, one of the first straightening member 1 and the second straightening member 2 is fixedly connected to the base 5, and the other is connected by a driving member such as a cylinder or a linear servo module. Taking the first straightening member 1 being fixedly connected to the base 5 and the second straightening member 2 being connected to the base 5 by a cylinder as an example, when the telescopic end of the cylinder expands and contracts, it controls the second straightening member 2 to approach or move away from the first straightening member 1, and the distance adjustment between the first straightening member 1 and the second straightening member 2 can also be achieved.

[0066] In some other alternative embodiments, the second driving member 32 may further include components capable of performing linear motions such as a linear servo module and an electric telescopic rod.

[0067] In this embodiment, the wire straightening device further includes a wire pressing member 4 and a third driving member 33. The third driving member 33 is used to drive the wire pressing member 4 to press the wire 7 placed between the straightening groove 11 and the straightening head 21 against the carrier 6 to fix the wire 7. Specifically, the third driving member is disposed on the base 5, the wire pressing member 4 is disposed on the third driving member 33, and the third driving member 33 is used to drive the wire pressing member 4 to press the wire 7 received on the carrier 6. Specifically, for some wires 7 received on the carrier 6, a corresponding wire pressing member 4 is provided. The wire 7 is received on the carrier 6 close to the straightening device. When the to-be-straightened end of the wire 7 is placed between the straightening groove 11 and the straightening head 21, that is, when the to-be-straightened end of the wire 7 extends between the first straightening member 1 and the second straightening member 2, the wire pressing member 4 can approach the carrier 6 under the action of the third driving member 33 and press the wire 7 against the carrier 6, so as to realize the fixation between the wire 7 and the carrier 6 and avoid the situation of the wire 7 on the carrier 6 moving and slipping during the subsequent straightening work.

[0068] Exemplarily, the third driving member 33 includes a second moving driving cylinder. The fixed end of the second moving driving cylinder is fixed to the base 5, and the wire pressing member 4 is fixed to the telescopic end of the second moving driving cylinder. Specifically, the telescopic end of the second moving driving cylinder can expand and contract relative to the fixed end along the second direction to drive the wire pressing member 4 to move.

[0069] In some other alternative embodiments, the third driving member 33 may further include components capable of performing linear motions such as a linear servo module and an electric telescopic rod.

[0070] Specifically, the carrier 6 is provided with a wire clamping groove 611 for the wire 7 to pass through. One end of the wire pressing member 4 facing the wire clamping groove 611 is provided with a pressing head 41 for pressing the wire 7 into the wire clamping groove 611. Specifically, a wire clamping block 61 is fixedly arranged on the carrier 6, and the wire clamping groove 611 is opened on the wire clamping block 61. The wire 7 can sequentially pass through the wire clamping groove 611 and the straightening groove 11 along the first direction. Specifically, the shape of the wire clamping groove 611 is set to be V-shaped.

[0071] Optionally, a fixing groove (not shown) is also provided on the vehicle 6, and the fixing groove is used to fixedly place an object connected to the wire 7. Exemplarily, taking the magnetic ring 72 and the core wire 71 as an example, the magnetic ring 72 is fixedly placed in the fixing groove, and the core wire 71 extends outward after passing through the wire clamping groove 611.

[0072] Exemplarily, the following is a description of the straightening process of the core wire 71 of the magnetic ring 72 by applying this wire straightening device.

[0073] First, the connected magnetic ring 72 and core wire 71 are loaded into the vehicle 6. Specifically, the magnetic ring 72 is fixedly placed in the fixing groove, and the core wire 71 passes through the wire clamping groove 611 and extends outward. The vehicle 6 is moved to one side of the first straightening member 1 and the second straightening member 2 through a component such as a conveyor belt that has functions of conveying and supporting. Specifically, reference can be made to Figure 7 as shown.

[0074] Continue to refer to Figure 7 as shown. In the initial state, the first driving member 31 drives a certain distance between the first straightening member 1 and the second straightening member 2 in the second direction, that is, the corresponding wire straightening groove 11 and the wire straightening head 21 are arranged at intervals in the second direction, ensuring that the end of the core wire 71 to be straightened can pass through the first straightening member 1 and the second straightening member 2 along the first direction, and in the first direction, the first straightening member 1 and the second straightening member 2 are in a position close to the vehicle 6. The pressing member 4 is located above the vehicle 6.

[0075] When the vehicle 6 is placed in place, the pressing head 41 of the pressing member 4 is arranged opposite to the wire clamping groove 611. Referring to Figure 8 as shown, the third driving member 33 drives the pressing member 4 to descend, so that the pressing head 41 at one end of the pressing member 4 facing the wire clamping groove 611 presses the core wire 71 into the wire clamping groove 611, thereby fixing the core wire 71 and preventing the core wire 71 from moving and slipping during subsequent straightening work.

[0076] Subsequently, referring to Figure 9 as shown, the first driving member 31 works to drive the second straightening member 2 to approach the first straightening member 1. During the process, the insertion portion 23 first inserts into the insertion groove 12. As the insertion portion 23 continues to insert, the first end of the wire straightening head 21 further extends into the wire straightening groove 11 and jointly holds the core wire 71 with the wire straightening groove 11. During the process, the elastic member 22 is gradually compressed, providing elastic buffering for the wire straightening head 21 to prevent hard contact with the core wire 71.

[0077] Next, referring to Figure 10 as shown, the second driving member 32 drives the first straightening member 1 and the second straightening member 2 to move along the first direction away from the vehicle 6. During the process, the wire straightening head 21 and the wire straightening groove 11 jointly hold and smooth both sides of the core wire 71, thereby performing a straightening action on the core wire 71.

[0078] Further, with reference to Figure 11 As shown, after the straightening operation of the core wire 71 is completed, the straightening head 21 and the straightening groove 11 are separated from the contact with the core wire 71 as the first straightening member 1 and the second straightening member 2 move. Subsequently, the third driving member 33 drives the pressing member 4 to rise, releasing the pressing on the core wire 71. Then, the core wire 71 can be removed from the carrier 6, and the straightened core wire 71 can be taken out.

[0079] In summary, the wire straightening device provided in this embodiment can perform fast and reliable automatic straightening work on the wire 7, liberate manpower, ensure the straightening effect, and avoid damaging the wire 7.
