[0033] In headphones, such as bone conduction headphones, the backband assembly is a key component, connecting between the two earhook assemblies or speaker assemblies to provide support and signal transmission. The backband assembly is curved and, when worn, is often placed around the back of the head, between the ears, or around the top of the head, between the ears.

[0034] like Figure 2 As shown, the rear suspension assembly includes an elastic sleeve 1 and a metal wire 2, wherein the metal wire 2 is inserted into the elastic sleeve 1 and partially protrudes from both ends of the elastic sleeve 1. The elastic sleeve 1 can be a silicone sleeve or a plastic sleeve, and the metal wire 2 can be a titanium wire, copper wire, or aluminum wire. The elastic sleeve 1 is arc-shaped, and the metal wire 2 is also arc-shaped. The metal wire 2 is inserted into the elastic sleeve 1 along an arc-shaped trajectory. After insertion, it needs to remain relatively fixed to the elastic sleeve 1. Glue can be applied to secure the elastic sleeve 1 and the metal wire 2.

[0035] The assembly of the rear hanging assembly requires the separate elastic sleeve 1 and the metal wire 2 to be assembled as follows Figure 2The rear hanging assembly shown in FIG. Wherein, the elastic sleeve 1 and the metal wire 2 are pre-assembled into Figure 1 The rear hanging assembly shown in the figure is then assembled by passing the metal wire 2 through the elastic sleeve 1 to form Figure 2 The status shown.

[0036] During the assembly process of the rear hanging components, manual threading is used, which easily fatigues workers, has low efficiency and high costs.

[0037] Based on this, the present application provides a wire threading device 100, see Figure 3 and Figure 4 , Figure 1 This is a structural diagram of an embodiment of the wire threading device provided by this application. Figure 4 yes Figure 3 The schematic diagram of the structure of the wire threading jig in the wire threading equipment shown.

[0038] The wire threading device 100 includes a wire threading jig 10, a first wire threading device 20, a second wire threading device 30, a conveying mechanism 40, a picking device 50, a first gluing device 60 and a second gluing device 70. The first gluing device 60, the first wire threading device 20, the second gluing device 70 and the second wire threading device 30 are arranged in sequence along the conveying direction of the conveying mechanism 40, that is, the conveying mechanism 40 conveys the wire threading jig 10 through the first gluing device 60, the first wire threading device 20, the second gluing device 70 and the second wire threading device 30 in sequence to perform corresponding operations; there are two picking devices 50, and the two picking devices 50 are respectively arranged corresponding to the first wire threading device 20 and the second wire threading device 30.

[0039] In other embodiments, the number of the picking device 50 may also be one, so that it is provided corresponding to the first wire threading device 20 and the second wire threading device 30 .

[0040] Among them, the wire threading jig 10 is used to fix the elastic sleeve 1 and assist the metal wire 2 to be threaded into the elastic sleeve 1; the conveying mechanism 40 is used to convey the wire threading jig 10 carrying the elastic sleeve 1 and the metal wire 2, and passes through the first gluing device 60, the first wire threading device 20, the second gluing device 70 and the second wire threading device 30 in sequence; the first gluing device 60 is used to pre-coat glue before threading, the first wire threading device 20 is used to thread the metal wire 2 and the elastic sleeve 1 for the first time, the second gluing device 70 is used to fill glue after one threading, and the second wire threading device 30 is used to thread the metal wire 2 and the elastic sleeve 1 for the second time; the picking device 50 is used to pick up the wire threading jig 10 from the conveying mechanism 40 and place it in the first wire threading device 20 or the second wire threading device 30, and pick up the wire threading jig 10 from the first wire threading device 20 or the second wire threading device 30 and place it on the conveying mechanism 40.

[0041] The glue applied can also lubricate the elastic sleeve 1 and the metal wire 2 to facilitate the insertion of the metal wire 2 into the elastic sleeve 1 . After the insertion is completed, the glue solidifies after a period of time to fix the elastic sleeve 1 and the metal wire 2 .

[0042] After the metal wire 2 and the elastic sleeve 1 undergo two threading processes, the threading assembly is completed, so that the metal wire 2 is threaded through the elastic sleeve 1 and exposed from both ends of the elastic sleeve 1.

[0043] Optionally, only one of the first gluing device 60 and the second gluing device 70 may be provided, that is, the one may complete the gluing before and during the threading of the wire.

[0044] In other embodiments, the first gluing device 60 and the second gluing device 70 may not be provided, and manual gluing may be used instead of mechanical gluing; or, the conveying mechanism 40 may not be provided, and a picking device 50 may be used to replace the function of the conveying mechanism 40; or, manual labor may be used to replace the conveying mechanism 40, the picking device 50, the first gluing device 60 and the second gluing device 70.

[0045] In this embodiment, the conveying mechanism 40 includes a belt and a rotating shaft. The rotating shaft drives the belt to move. The belt is used to convey the wire threading jig 10. The first gluing device 60, the first wire threading device 20, the second gluing device 70 and the second wire threading device 30 are arranged in sequence along the conveying direction of the belt.

[0046] Optionally, the conveying mechanism 40 can also be a plurality of groups of rollers arranged along the conveying direction, and a carrying disk is provided on the carrying surface formed by the plurality of groups of rollers. The wire threading jig 10 is placed on the carrying disk for conveying the wire threading jig 10.

[0047] The picking device 50 includes a gripper and a moving mechanism. The moving mechanism is arranged across the top of the first wire threading device 20 or the second wire threading device 30. The moving mechanism is connected to the gripper and is used to drive the gripper to reciprocate along the conveying direction of the conveying mechanism 40 to continuously pick up and place the wire threading jig 10. The gripper can be a pneumatic gripper that picks up the picking hole 154 on the wire threading jig 10 by alignment to grab the wire threading jig 10; the gripper can also be a suction cup that picks up the wire threading jig 10 by adsorption. The moving mechanism includes a transverse moving component and a lifting component. The transverse moving component is used to drive the gripper to reciprocate along the conveying direction of the conveying mechanism 40, and the lifting component is used to drive the gripper to rise and fall; the transverse moving component and the lifting component can be a belt component or a slider guide component.

[0048] The first glue coating device 60 is provided upstream of the first wire threading device 20 and is used to coat glue on the end of the elastic sleeve 1 before the metal wire 2 is inserted into the end of the elastic sleeve 1 so that the metal wire 2 passes through the elastic sleeve 1 after being coated with glue.

[0049] The second glue coating device 70 is disposed between the first wire threading device 20 and the second wire threading device 30 , and is used to apply glue to the end of the elastic sleeve 1 after the first wire threading is completed.

[0050] Both the first and second gluing devices 60 and 70 include a gluing machine and a transmission mechanism. The gluing machine is located at the actuator end of the transmission mechanism. The transmission mechanism is used to transport the gluing machine to the gluing position and align it with the port at one end of the elastic sleeve where the wire is inserted for gluing. The transmission mechanism can be a cylinder, a guide rail, and a slider. The cylinder drives the slider to slide along the guide rail, and the gluing machine is mounted on the slider. The transmission mechanism can include multiple sets of "cylinders, guide rails, and sliders," thereby enabling multi-directional transmission.

[0051] Optionally, the first gluing device 60 and the second gluing device 70 may also be gluing machines, which are fixed at corresponding positions. The conveying mechanism 40 conveys the wire threading jig 10 to the gluing station to align with the gluing machine.

[0052] See also Figure 4 and Figure 5 ,in Figure 5 yes Figure 4 Schematic diagram of the perspective structure of the wire threading fixture shown.

[0053] The wire threading jig 10 is used to assist in threading the metal wire 2 into the elastic sleeve 1. Specifically, the wire threading jig 10 is provided with a shaping channel 12, which is annular and extends through the wire threading jig 10 and exposes two ports 120 on one side of the wire threading jig 10. A guide groove 14 is provided on a side surface 132 of the wire threading jig 10 in the thickness direction. The guide groove 14 is spaced apart from the shaping channel 12 in the thickness direction. The shaping channel 12 is used to position the elastic sleeve 1, and the guide groove 14 is used to guide the metal wire 2 to be threaded through the elastic sleeve 1.

[0054] It should be noted that the thickness direction is perpendicular to the surface 132 of the wire threading jig 10 .

[0055] The shaping channel 12 is used to shape the elastic sleeve 1 . One end of the metal wire 2 is pre-inserted into the elastic sleeve 1 through the port 120 , and the other end thereof cooperates with the guide groove 14 to pass through the elastic sleeve 1 under the guidance of the guide groove 14 .

[0056] The shaping channel 12 is arranged in an arc shape, and the arc shape of the shaping channel 12 is adapted to the arc shape of the elastic sleeve 1 . The two ports 120 are arranged on the same side of the wire threading jig 10 , and the two ports 120 are inclined toward each other to facilitate the threading of the metal wire 2 .

[0057] The arc shape of the wire guide groove 14 matches the arc shape of the metal wire 2 , so that the wire guide groove 14 can basically maintain the original shape of the metal wire 2 and avoid deformation of the metal wire 2 .

[0058] The aspect ratio of the metal wire 2 is extremely large. If the metal wire 2 is not restricted and is simply driven by external force to pass through the elastic sleeve 1, it is very easy to cause the metal wire 2 to shake uncontrollably and be difficult to pass through the elastic sleeve 1.

[0059] The present application provides a wire guide groove 14 on one side of the wire threading jig 10 in the thickness direction to limit and guide the metal wire 2. The wire guide groove 14 can support the metal wire 2 and prevent the metal wire 2 from shaking uncontrollably due to its own strong flexibility. Therefore, under the action of driving force, the metal wire 2 can be passed along the wire guide groove 14 into the elastic sleeve 1, thereby improving the wire threading efficiency.

[0060] In other embodiments, the elastic sleeve 1 may also be clamped on one side of the wire threading jig 10 , which is not specifically limited in this application.

[0061] In this embodiment, the depth of the guide groove 14 is smaller than the diameter of the metal wire 2, so that after the metal wire 2 is accommodated in the guide groove 14, it can be partially exposed from the guide groove 14, so that other structural parts do not need to be inserted into the guide groove 14 to push one end of the metal wire 2 to move along the guide groove 14.

[0062] Optionally, the depth of the wire guide groove 14 is greater than or equal to the diameter of the metal wire 2 , and the structural member can be inserted into the wire guide groove 14 to push one end of the metal wire 2 to move along the wire guide groove 14 .

[0063] Furthermore, the wire threading jig 10 is also provided with a wire guide channel 16 that passes through the wire threading jig 10 in the thickness direction, and the wire outlet port of the wire guide channel 16 is located on the same side as the two ports 120 of the shaping channel 12 , and one end of the wire guide groove 14 is connected to the wire guide channel 16 .

[0064] The wire guide groove 14 is used to guide the metal wire 2 to pass through the elastic sleeve 1 for the first time, and the wire guide channel 16 is used to guide the metal wire 2 to pass through the elastic sleeve 1 for the second time.

[0065] The wire guide channel 16 and the wire guide groove 14 have substantially the same curvature, so as to be able to conveniently and unhindered receive the metal wire 2 transferred from the wire guide groove 14 and guide the metal wire 2 to continue to pass through the elastic sleeve 1 .

[0066] like Figure 5As shown, the lead channel 16 is located in the area formed by the shaping channel 12 to avoid interference between the lead channel 16 and the shaping channel 12; the projection of one end of the lead groove 14 on the plane where the shaping channel 12 is located along the thickness direction is located in the area formed by the shaping channel 12, and one end of the lead groove 14 is connected to the lead channel 16; in other words, the projection of the lead groove 14 and the shaping channel 12 on the same plane along the thickness direction has one end of the lead groove 14 located in the area formed by the shaping channel 12, and one end of the lead groove 14 is connected to the lead channel 16.

[0067] The guide groove 14 may be located in the area formed by the shaping channel 12 ; or part of the guide groove 14 may be located in the area formed by the shaping channel 12 , and part of the guide groove 14 may be located outside the area formed by the shaping channel 12 .

[0068] In this embodiment, the guide groove 14 intersects with the projection of the shaping channel 12 in the thickness direction, that is, the guide groove 14 spans the area formed by the shaping channel 12, and the length of the guide groove 14 can be relatively extended to provide a longer guiding stroke for the metal wire 2.

[0069] Continue reading Figure 4 and Figure 5 The wire threading jig 10 is also provided with an inlet channel 18 that passes through the wire threading jig 10 in the thickness direction, and the inlet port of the inlet channel 18 is located on the same side as the two ports 120 of the shaping channel 12, and the curvature radius of the inlet channel 18 is the same as the curvature radius of the lead channel 16; the inlet channel 18 is used to accommodate a driving member that drives the metal wire 2, so that the driving member is separated from the metal wire 2 after the metal wire 2 is passed through the elastic sleeve 1.

[0070] The storage channel 18 and the lead channel 16 can have arcs of different lengths. During the secondary wire threading process, the driving member is inserted into the lead channel 16 and drives one end of the metal wire 2 to drive the metal wire 2 to be threaded into the elastic sleeve 1. After the metal wire 2 and the elastic sleeve 1 are threaded, the driving member continues to move and can be accommodated in the storage channel 18 and separated from the metal wire 2.

[0071] In other embodiments, after the driving member drives the metal wire 2 and the elastic sleeve 1 to complete the threading, the driving member can be withdrawn to separate from the metal wire 2 .

[0072] In this embodiment, the storage channel 18 and the lead channel 16 are symmetrically arranged, that is, the storage channel 18 and the lead channel 16 have the same curvature, which can facilitate the manufacture of the wire threading jig 10 and the accommodation of the driving part, and facilitate the reservation of movement margin to avoid the driving part colliding with the wire threading jig 10.

[0073] See also Figures 4 to 6 , Figure 6 yes Figure 4Schematic diagram of the exploded structure of the wire threading jig shown.

[0074] In this embodiment, the wire threading jig 10 includes a first carrier plate 11 and a second carrier plate 13, the first carrier plate 11 is provided with a first shaping groove 110, the second carrier plate 13 is provided with a second shaping groove (not shown) on the side facing the first carrier plate 11, and the side surface 132 of the second carrier plate 13 facing away from the first carrier plate 11 is provided with a guide groove 14; wherein the first carrier plate 11 and the second carrier plate 13 are interlocked along the thickness direction of the wire threading jig 10, so that the first shaping groove 110 and the second shaping groove are enclosed to form a shaping channel 12.

[0075] The first carrier plate 11 and the second carrier plate 13 cooperate to form the aforementioned wire guide channel 16 and storage channel 18 .

[0076] In another embodiment, the wire threading jig 10 may further include a carrier plate and a cover plate, wherein the carrier plate is provided with a groove and a shaping channel 12 arranged at the bottom of the groove, and the cover plate is arranged in the groove and seals one side of the shaping channel 12.

[0077] In this embodiment, the size of the first shaping groove 110 and the size of the second shaping groove 130 are slightly larger than the size of the elastic sleeve 1 , so as to accommodate the elastic sleeve 1 and reduce the manufacturing difficulty.

[0078] The wire threading jig 10 also includes a plurality of elastic pads (not shown), and elastic pads are embedded at both ends of the first shaping groove 110 and both ends of the second shaping groove 130. The elastic pads are used to support the ends of the elastic sleeve 1 to fix the elastic sleeve 1 and prevent the elastic sleeve 1 from moving relative to the first carrier plate 11 and the second carrier plate 13, thereby improving the wire threading efficiency.

[0079] The elastic pad can be a silicone pad or a sponge, etc., so as to use its own elasticity to appropriately adjust the tightness between the wire threading jig 10 and the elastic sleeve 1 to prevent the elastic sleeve 1 and the wire threading jig 10 from being too loose and sliding.

[0080] Furthermore, two symmetrical first magnetic members 112 are provided on the first carrier 11, and the first magnetic members 112 are located on the outer periphery of the first shaping groove 110 and close to the end of the first shaping groove 110. The first carrier 11 is also provided with two spaced second magnetic members 114, and the two second magnetic members 114 are located on the symmetry line of the first shaping groove 110 and are distributed up and down. The two second magnetic members 114 are also located in the area surrounded by the first shaping groove 110; the second carrier 13 is provided with a third magnetic member (not shown) corresponding to the first magnetic member 112 and a fourth magnetic member (not shown) corresponding to the second magnetic member 114.

[0081] The first magnetic member 112 and the second magnetic member 114 can be permanent magnets or ferromagnets. One of the first magnetic member 112 and the third magnetic member is a permanent magnet, and the other is a permanent magnet or a ferromagnet. One of the second magnetic member 114 and the fourth magnetic member is a permanent magnet, and the other is a permanent magnet or a ferromagnet.

[0082] The shaping channel 12 is arranged in a ring with a long length. The first magnetic component 112 is located on the outer periphery of the first shaping groove 110 and close to the end of the first shaping groove 110. It can fix the two ends of the shaping channel 12 to prevent the shaping of the elastic sleeve 1 from failing due to the loosening of the end of the shaping channel 12; the two second magnetic components 114 are located on the symmetry line of the first shaping groove 110 to provide magnetic attraction in the middle of the wire threading jig 10, so that the first carrier plate 11 and the second carrier plate 13 are more firmly combined.

[0083] Furthermore, the first carrier plate 11 is provided with one of the positioning posts 150 and the positioning holes 152 , and the second carrier plate 13 is provided with the other of the positioning posts 150 and the positioning holes 152 . The positioning posts 150 and the positioning holes 152 are aligned and assembled.

[0084] Furthermore, the first carrier plate 11 and the second carrier plate 13 are both provided with a picking hole 154 for picking up the wire threading jig 10 through the picking hole 154 .

[0085] See also Figure 3 and Figure 4 In this embodiment, the first wire threading device 20 is used to drive the metal wire 2 along the wire groove 14 to the wire channel 16 to pass through the elastic sleeve 1 to complete the first wire threading; the second wire threading device 30 is used to drive the metal wire 2 along the wire channel 16 to pass through the elastic sleeve 1 to complete the second wire threading.

[0086] See Figures 7 and 8 ,in Figure 7 yes Figure 3 The schematic structural diagram of the first wire threading device in the wire threading device shown is as follows, Figure 8 yes Figure 7 The schematic diagram of the first threading device on one axis side is shown. Figure 9 yes Figure 7 Another axial structural schematic diagram of the first wire threading device is shown.

[0087] Among them, the first wire threading device 20 includes a first wire threading mechanism 22 and a first limiting mechanism 24, the first wire threading mechanism 22 includes a first baffle 220 and a first swinging member 221 arranged on the first baffle 220; the first limiting mechanism 24 includes a first push plate 240 and a first limiting member 242 arranged on the side of the first push plate 240 facing the first baffle 220, and a first annular guide surface 244 is provided on one side of the first limiting member 242. The first annular guide surface 244 and the first baffle 220 and the first push plate 240 clamped on both sides thereof cooperate to form a first limiting channel (not shown).

[0088] The curved arc shape of the first annular guide surface 244 imitates the arc shape of the metal wire 2 , that is, the arc shape of the first annular guide surface 244 is substantially the same as the arc shape of the metal wire 2 , thereby effectively guiding the metal wire 2 to pass through the elastic sleeve 1 .

[0089] One end of the first limiting channel is connected to the lead channel 16, and the other end of the first limiting channel guides the port 120 of the shaping channel 12. The first limiting channel is used to guide the metal wire 2 to pass through the elastic sleeve 1; the first swinging member 221 is used to drive the metal wire 2 to pass along the lead groove 14, the lead channel 16 and the first limiting channel. The first swinging member 221 drives one end of the metal wire 2 to move along the lead groove 14 to the lead channel 16 to complete one wire threading.

[0090] Specifically, the first baffle 220 and the first push plate 240 are clamped on opposite sides of the wire threading jig 10 along the thickness direction of the wire threading jig 10, and a first limiting member 242 is located on one side of the port 120 of the wire threading jig 10, and the first limiting member 242 also presses against the first baffle 220 at one end thereof, so that the first baffle 220, the first push plate 240, the first limiting member 242 and the wire threading jig 10 together form the first limiting channel to guide the metal wire 2 to be threaded through the elastic sleeve 1, and prevent the metal wire 2 from being severely deformed during movement and becoming difficult to thread through the elastic sleeve 1, that is, the first limiting channel can keep the metal wire 2 from deforming less during movement, so that the first swinging member 221 can push against one end of the metal wire 2.

[0091] The first limiting mechanism 24 also includes a first guide member 241 arranged on one side of the first push plate 240. The first guide member 241 is used to be assembled on the guide channel 16 of the wire threading jig 10, and the side of the first guide member 241 facing the first baffle 220 is aligned with the bottom surface of the guide groove 14, which is equivalent to extending the length of the guide groove 14. Therefore, the side of the first guide member 241 facing the first baffle 220 can be used to support the metal wire 2 to prevent the metal wire 2 from being unable to pass through the elastic sleeve 1 due to bending and stretching toward the guide channel 16.

[0092] Furthermore, the first guide member 241 also extends toward the first annular guide surface 244 to guide the metal wire 2 to the first annular guide surface 244, thereby further increasing the guidance and limiting support for the metal wire 2 and reducing the risk of deformation of the metal wire 2 during the threading process.

[0093] Furthermore, the first limiting mechanism 24 also includes a second guide member 243 arranged on one side of the first push plate 240. The second guide member 243 is used to be assembled on the storage channel 18 of the wire threading jig 10, and cooperates with the first annular guide surface 244 to form a guide gap for the metal wire 2 to pass through. The guide gap is aligned with the port 120 on the wire threading jig 10. The metal wire 2 passes through the guide gap and, under the guidance of the second guide member 243, penetrates into the elastic sleeve 1 on the wire threading jig 10.

[0094] The second guide member 243 further strengthens the support and guiding effect on the metal wire 2 , thereby improving the efficiency and convenience of passing the metal wire 2 through the elastic sleeve 1 .

[0095] In this embodiment, the first wire threading device 20 also includes a first supporting assembly 26, and the first supporting assembly 26 includes a first carrier 260. The first carrier 260 is arranged between the first baffle 220 and the first push plate 240. The first carrier 260 is used to carry the wire threading jig 10 equipped with an elastic sleeve 1 and a metal wire 2 to limit the wire threading jig 10 so that one end of the metal wire 2 can be more accurately aligned with the first swinging member 221.

[0096] Specifically, the first carrier 260 is provided with a limiting groove 262 assembled with the wire threading jig 10, and the side of the wire threading jig 10 away from the port 120 is inserted into the limiting groove 262, and the side of the wire threading jig 10 having the lead groove 14 is exposed from the first carrier 260 and faces the first baffle 220.

[0097] A clearance opening 263 is formed on a side of the first carrier 260 facing the first baffle 220 , through which the wire guide groove 14 and the metal wire 2 on the wire threading jig 10 are exposed to the first wire threading mechanism 22 .

[0098] At least one of the first baffle 220 and the first carrier 260 is further provided with a positioning protrusion 264, which is arranged around the avoidance opening 263 and can form a gap between the wire threading jig 10 located on the first carrier 260 and the first baffle 220 for the first swinging member 221 to swing.

[0099] The positioning protrusion 264 may be a rib or a plurality of protrusions provided along the edge of the avoidance opening 263 .

[0100] In this embodiment, a positioning protrusion 264 is provided on the first carrier 260 around the avoidance opening 263, and a groove 223 is provided on the side of the first baffle 220 facing the first carrier 260. The positioning protrusion 264 is also inserted into the groove 223, so that a gap is formed between the wire threading jig 10 on the first carrier 260 and the first baffle 220. This gap allows one end of the metal wire 2 to be aligned with the first swinging member 221. The first swinging member 221 acts on one end of the metal wire 2, so that the metal wire 2 can be forced through the gap along the guide groove 14 to pass through the elastic sleeve 1.

[0101] In other embodiments, the first baffle 220 may be provided with the positioning protrusion 264 ; or both the first baffle 220 and the first carrier 260 may be provided with the positioning protrusion 264 , and the two positioning protrusions 264 may be in contact with each other.

[0102] In this embodiment, the first wire threading device 20 also includes a base plate 21 and a support plate 23 arranged at one end of the base plate 21, wherein the first baffle 220 is fixed to the other end of the base plate 21, the first baffle 220 and the support plate 23 are spaced apart, and a guide rod 25 is arranged between the two support plates 23, the first carrier 260 and the first push plate 240 are slidably passed through the guide rod 25, and then the first carrier 260 and the first push plate 240 are slidably arranged between the two support plates 23, wherein the first carrier 260 is slidably arranged between the first baffle 220 and the first push plate 240.

[0103] Specifically, the first bearing assembly 26 further includes a first bearing driver 265 , which is connected to the first carrier 260 and is used to drive the first carrier 260 to move between the first stop plate 220 and the first push plate 240 .

[0104] The first bearing driving member 265 can be a cylinder, which is fixed to another support plate 23 and passes over the first push plate 240 to push the first carrier 260 to move toward the first baffle 220 under the guidance of the guide rod 25, so that the positioning protrusion 264 is inserted into the groove 223.

[0105] Optionally, the first bearing driving member 265 may further include a motor and a screw assembly, and the motor drives the first carrier 260 to move toward the first baffle 220 under the guidance of the guide rod 25 through the screw assembly.

[0106] The first limiting mechanism 24 further includes a limiting driving member 246 , which is connected to the first push plate 240 and is used to drive the first push plate 240 to move toward the first baffle 220 to form a first limiting channel.

[0107] The position-limiting driving component 246 may be a cylinder, and the position-limiting driving component 246 may also include a motor and a screw assembly to drive the first push plate 240 to move toward the first baffle plate 220 .

[0108] Furthermore, a buffer is provided between the support plate 23 on which the first baffle 220 is installed and the first carrier 260 , and a buffer is also provided between the first push plate 240 and the first carrier 260 to avoid collision between the first baffle 220 , the first carrier 260 and the first push plate 240 .

[0109] See also Figure 10 and Figure 11 , Figure 10 yes Figure 3 The structural diagram of the second wire threading device in the wire threading device shown is as follows, Figure 11 yes Figure 10 A schematic diagram of the structure of an axial side of the second wire threading device is shown.

[0110] The second wire threading device 30 includes a second wire threading mechanism 32 and a second limiting mechanism 34. The second wire threading mechanism 32 includes a second baffle 320 and a second swinging member 321 arranged on the second baffle 320; the second limiting mechanism 34 includes a second push plate 340 and a second limiting member 342 arranged on the side of the second push plate 340 facing the second baffle 320. A second annular guide surface 344 is provided on one side of the second limiting member 342. The second annular guide surface 344 and the second baffle 320 and the second push plate 340 clamped on both sides thereof cooperate to form a second limiting channel (not shown).

[0111] The curved arc shape of the second annular guide surface 344 imitates the arc shape of the metal wire 2 , that is, the arc shape of the second annular guide surface 344 is substantially the same as the arc shape of the metal wire 2 , thereby effectively guiding the metal wire 2 to pass through the elastic sleeve 1 .

[0112] One end of the second limiting channel is connected to the lead channel 16 , and the other end of the second limiting channel leads to the port 120 of the shaping channel 12 . The second limiting channel is used to guide the metal wire 2 to pass through the elastic sleeve 1 .

[0113] The second swinging member 321 is used to be inserted into the lead channel 16, driving the metal wire 2 to pass along the lead channel 16 and the second limiting channel, and separate from the metal wire 2 at the entrance port of the entrance channel 18. The second swinging member 321 is housed in the entrance channel 18 to complete the second wire threading, so that the metal wire 2 is passed through the elastic sleeve 1 and both ends of the metal wire 2 are exposed from the elastic sleeve 1.

[0114] The second baffle 320 and the second push plate 340 are clamped on opposite sides of the wire threading jig 10 along the thickness direction of the wire threading jig 10, and a second limiting member 342 is located on one side of the port 120 of the wire threading jig 10, and the second limiting member 342 is also pressed against the second baffle 320 at one end thereof facing the second baffle 320, so that the second baffle 320, the second push plate 340, the second limiting member 342 and the wire threading jig 10 together form the second limiting channel to guide the metal wire 2 to be passed through the elastic sleeve 1, and prevent the metal wire 2 from being severely deformed during movement and becoming difficult to pass through the elastic sleeve 1, that is, the second limiting channel can keep the metal wire 2 from deforming less during movement, so that the second swinging member 321 can push against one end of the metal wire 2.

[0115] In this embodiment, the second baffle 320 swings along with the second swinging member 321, that is, the second baffle 320 can rotate along the trajectory of the second limiting member 342 and be blocked on one side of the second limiting member 342 to ensure that the part of the second limiting channel through which the metal wire 2 is passed is limited.

[0116] Specifically, in actual applications, the second limiting channel has high requirements on size, and the width and thickness of the second limiting channel are relatively small to ensure that it can provide reliable support, limitation and guidance for the metal wire 2, and avoid obvious deformation of the metal wire 2 in the second limiting channel.

[0117] The second swinging member 321 has a certain thickness and needs to be inserted into the lead-in channel 16 to push one end of the metal wire 2 .

[0118] The second swing member 321 includes a swing portion 325 and a tooth portion 324 provided at one end of the swing portion 325 . The tooth portion 324 is provided perpendicular to the swing portion 325 and extends toward the second push plate 340 . The tooth portion 324 is used to push the metal wire 2 to pass through.

[0119] In this embodiment, the tooth portion 324 spans the second baffle 320 and is inserted into the lead channel 16, that is, the swing portion 325 is arranged on the side of the second baffle 320 away from the second limiting member 342, thereby avoiding the increase in the size of the second limiting channel in the same direction due to the thickness of the second swing member 321, so that the second limiting channel can provide a strong guiding effect for the metal wire 2.

[0120] Optionally, the second swinging member 321 may also be a tooth portion 324 , which is connected to the second baffle 320 and is inserted into the lead channel 16 .

[0121] Furthermore, the second limiting mechanism 34 also includes a guide member 343, which is arranged on the side of the second push plate 340 facing the second baffle 320. The guide member 343 is used to be assembled in the guide channel 16 of the wire threading jig 10, and the depth of the guide member 343 inserted into the guide channel 16 is less than the thickness of the wire threading jig 10, so as to reduce the range of movement of the metal wire 2 in the thickness direction of the guide channel 16 and provide more reliable limitation for the metal wire 2.

[0122] Furthermore, the second limiting mechanism 34 also includes an arcuate guide member 341 arranged on the side of the second push plate 340 facing the second baffle 320. The arcuate guide member 341 is arranged below the second limiting member 342. The side of the arcuate guide member 341 facing the second annular guide surface 344 is an arcuate guide surface 345. The arcuate guide surface 345 cooperates with the second annular guide surface 344 to guide the metal wire 2 to pass through, that is, the metal wire 2 passes between the arcuate guide surface 345 and the second annular guide surface 344.

[0123] The arc-shaped guide surface 345 and the second annular guide surface 344 limit the metal wire 2 from the upper and lower sides respectively, and the second push plate 340 and the second baffle plate 320 limit the metal wire 2 from the left and right sides respectively, that is, the second limiting channel can limit and guide the metal wire 2 in all directions to ensure that the free end of the metal wire 2 that is not inserted into the elastic sleeve 1 can be reliably supported and limited when passing through the second limiting channel, which can effectively reduce the risk of the free end of the metal wire 2 being separated from the second swinging member 321 when passing through the second limiting channel.

[0124] In this embodiment, the second wire threading device 30 also includes a second supporting assembly 36, which includes a second carrier 360. The second carrier 360 is arranged between the second baffle 320 and the second push plate 340. The second carrier 360 is provided with a limiting groove 362 for supporting the wire threading jig 10.

[0125] The second wire threading device 30 also includes a base plate 31 and a support plate 33 arranged at one end of the base plate 31. The second push plate 340 is fixed to the other end of the base plate 31 and is spaced apart from the support plate 33. A guide rod 35 is also provided between the second push plate 340 and the support plate 33. The second carrier 360 and the supporting plate 37 are slidably passed through the guide rod 35; the driving motor 322 is arranged on the supporting plate 37, the second baffle 320 and the second swinging member 321 are connected to the output shaft of the driving motor 322, and the driving motor 322 drives the second baffle 320 and the second swinging member 321 to swing for the second wire threading.

[0126] The second carrier 360 is slidably disposed between the second push plate 340 and the supporting plate 37 . The second supporting assembly 36 further includes a second supporting driving member 365 , which is connected to the second carrier 360 and is used to drive the second carrier 360 to move between the second push plate 340 and the supporting plate 37 .

[0127] Alternatively, the second carrier drive 365 may be a cylinder, or may further include a motor and a screw assembly. The second carrier drive 365 is fixed to the support plate 33 and is used to push the second carrier 360 toward the second push plate 340 under the guidance of the guide rod 35.

[0128] The second wire threading mechanism 32 further includes a guide drive member 323, which is fixed to the support plate 33. The drive end of the guide drive member 323 is connected to the carrier plate 37, and is used to drive the carrier plate 37 to carry the second baffle plate 320 and the second swing member 321 to move toward the second push plate 340 to form a second limiting channel and allow the second swing member 321 to be inserted into the wire guide channel 16. The guide drive member 323 can be a cylinder, or it can include a motor and a screw assembly.

[0129] Buffers are further provided between the second push plate 340 and the second carrier 360 , and between the second carrier 360 and the supporting plate 37 to prevent collisions between them.

[0130] Based on this, the present application also provides a wire threading device, which can be the above-mentioned first wire threading device 20 or the above-mentioned second wire threading device 30. In other words, the above-mentioned first wire threading device 20 and the second wire threading device 30 are two embodiments of the wire threading device and will not be repeated.

[0131] Different from the prior art, the present application discloses a wire threading device. The device comprises a wire threading mechanism and a limiting mechanism. The wire threading mechanism comprises a baffle plate and a swinging member disposed on the baffle plate. The limiting mechanism comprises a push plate and a limiting member disposed on the side of the push plate facing the baffle plate. One side of the limiting member is provided with an annular guide surface. The baffle plate, the annular guide surface, and the push plate cooperate to form an arcuate limiting channel. The swinging member is used to push the metal wire along the arcuate limiting channel. The limiting channel can guide the metal wire to be threaded through the elastic sleeve, thereby preventing the metal wire from being severely deformed during movement, which would make it difficult to thread the elastic sleeve. This effectively improves the assembly efficiency between the metal wire and the elastic sleeve.

[0132] The above description is merely an embodiment of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
