[0051] In order to realize automatic needle threading and improve assembly efficiency, the present invention proposes an automatic needle threading device 100.

[0052] In some embodiments of the present invention, the automatic threading device 100 includes a frame 10, a wire feeding assembly 30 and a threading assembly 40. The frame 10 is configured to have a threading space 10a. The wire feeding assembly 30 is disposed on the frame 10 and is located above the threading space 10a, and is used to deliver the wire 301 to the threading space 10a. The threading assembly 40 is disposed on the frame 10 and has a hook 433. The hook 433 is located on the side of the threading space 10a and can be movably arranged to enter and exit the threading space 10a; wherein the hook 433 passes through the needle hole of the needle body 200 and hooks the wire 301 when entering the threading space 10a; the hook 433 brings the wire 301 into the needle hole of the needle body 200 when exiting the threading space 10a.

[0053] In one embodiment, the frame 10 includes a mounting seat 11 and a mounting frame 13, which can be manufactured and connected independently, or can be an integral structure. The mounting seat 11 is used to connect to the fixed platform, and the mounting frame 13 is arranged on the side of the mounting seat 11 away from the fixed platform. On the mounting seat 11, one side of the mounting frame 13 is formed with the threading space 10a.

[0054] In one embodiment, the wire 301 can be a nylon wire, and the needle body 200 is a steel needle, which is about 1 meter long and about 9 mm in diameter. One end or both ends of the steel needle are clamped by a separate device so that at least part of the needle body 200 is located in the threading space 10a, and the needle body 200 located in the threading space 10a has a needle hole.

[0055] It should be noted that the threading space 10a is the space area around the needle body 200 that does not change with its own movement when the needle body 200 reaches the designated threading position. The threading assembly 40 is located on the side of the threading space 10a. Preferably, when the needle body 200 is set horizontally, the hook 433 also moves horizontally, and the movement path of the hook 433 is roughly at right angles to the length direction of the needle body 200, so that the threading operation is smoother. Commonly, the hook 433 can be driven by a cylinder, an electric cylinder or a motor, etc., which is not limited here.

[0056] The wire feeding assembly 30 is located above the threading space 10a. Before the wire 301 reaches the threading space 10a, the hook 433 moves and passes through the needle hole to wait in the threading space 10a. In one embodiment, the wire 301 reaches the threading space 10a from the wire feeding assembly 30, and the landing point of the wire 301 in the threading space 10a is on the travel path of the hook 433. The hook 433 is formed with a hook wire groove 433a, and the wire 301 can be lowered from the wire feeding assembly 30 and pass through the hook wire groove 433a. In another embodiment, the wire 301 falls on one side of the waiting hook 433, and the hook 433 is formed with a hook wire groove 433a and a gap connecting the hook wire groove 433a. The wire feeding assembly 30 can guide the wire 301 through the gap into the hook wire groove 433a through a movable mechanism. After the hook 433 hooks the wire 301 , the driving member drives the hook 433 to return and pass through the needle hole and leave the threading space 10 a , and the wire 301 also passes through the needle hole, thus completing the threading operation of the needle body 200 .

[0057] Therefore, it can be understood that the present invention cooperates with the wire feeding assembly 30 and the threading assembly 40. After the needle body 200 is in place, the movably arranged curved hook 433 passes through the needle hole of the needle body 200 to reach the threading space 10a. The wire feeding assembly 30 feeds the wire 301 to the threading space 10a, and the curved hook 433 drives the wire 301 to pass through the needle hole to complete the threading operation, eliminating manual operation, thereby realizing automatic threading of the needle body 200 and improving efficiency.

[0058] Reference Figure 7 In one embodiment, the threading assembly 40 also includes a primary driving member 41 and a secondary driving member 42, the primary driving member 41 is connected to the frame 10, the secondary driving member 42 is connected to the movable end of the primary driving member 41, and the hook 433 is connected to the movable end of the secondary driving member 42; the primary driving member 41 is used to drive the secondary driving member 42 to approach or move away from the threading space 10a, and the secondary driving member 42 is used to drive the hook 433 to enter and exit the threading space 10a.

[0059] In this embodiment, the primary drive member 41 and the secondary drive member 42 can be arranged in sequence along the moving path of the hook 433, that is, the secondary drive member 42 is arranged between the primary drive member 41 and the needle body 200, the primary drive member 41 can be fixed to the frame 10 directly or through a connecting plate, and the secondary drive member 42 is connected to the movable end of the primary drive member 41 and is used to drive the hook 433 to move. After the hook 433 hooks the wire 301, the secondary drive member 42 first acts to make the hook 433 retract a distance. At this time, the wire 301 is tensioned, and the wire feeding assembly 30 feeds the wire again, and then the primary drive member 41 acts, the hook 433 returns to its original position, and the wire 301 passes through the needle hole smoothly. This method avoids the situation in which the movement of the hook 433 is difficult to control in the case of one-time driving, resulting in the wire 301 being easily tightened or stuck and difficult to smoothly achieve the threading operation, thereby ensuring the stability and smoothness of the device operation.

[0060] In addition, in another embodiment, the primary driving member 41 and the secondary driving member 42 are arranged up and down, the primary driving member 41 is connected to the frame 10, and the secondary driving member 42 is arranged above the primary driving member 41. While ensuring smooth operation, horizontal space can also be saved to a certain extent.

[0061] Of course, the arrangement of the primary drive member 41 and the secondary drive member 42 is not limited to this, and the two can be arranged in other forms. The threading assembly 40 can also be provided with multi-stage drive members. Under the premise of ensuring smooth threading, the number, position and operation order of the multi-stage drive members can be arranged according to actual conditions, and no further restrictions are made here.

[0062] Reference Figure 2 and Figure 7 In one embodiment, the threading assembly 40 also includes a first guide member 44, which is connected to the frame 10. The surface of the first guide member 44 is formed with a guide groove 44a extending along the moving path of the hook 433, and the unopened side edge of the hook 433 can be movably accommodated in the guide groove 44a.

[0063] In this embodiment, the first guide member 44 is roughly a block, and its side surface portion facing the hook 433 is recessed to form a guide groove 44a. The distance between the two side walls of the guide groove 44a is slightly larger than the thickness of the unopened side of the hook 433. The guide groove 44a extends in a straight line to make the movement path of the hook 433 clear and more stable.

[0064] Further, the threading assembly 40 is provided with a hook piece 43, and a hook 433 is fixed to one side of the hook piece 43. Optionally, the hook 433 and the hook piece 43 may be an integral structure, and one side of the hook piece 43 may be movably accommodated in the guide groove 44a, and the driving member drives the hook piece 43 to move. The hook piece 43 is provided so that more parts are accommodated in the guide groove 44a, and the movement of the hook 433 is further made more stable and reliable.

[0065] On this basis, the portion of the hook piece 43 accommodated in the guide groove 44a is defined as a guide edge 431. The guide edge 431 can be horizontal, and the hook 433 can be extended from one end of the guide edge 431 and bent away from the guide groove 44a to improve the integrity; the guide edge 431 can also be formed by bending one side of the hook piece 43. For example, when the hook piece 43 is horizontal, one side thereof is bent downward to form the guide edge 431. Correspondingly, the upper surface of the first guide member 44 is provided with a guide groove 44a to match the guide edge 431.

[0066] Alternatively, in other embodiments, the first guide member 44 may be provided with a guide edge 431, and the surface of the hook piece 43 may be provided with a guide groove 44a, and the guide edge 431 cooperates with the guide groove 44a to make the movement of the hook 433 more stable.

[0067] Reference Figure 1 and Figure 5 In one embodiment, the wire feeding assembly 30 includes a bracket 31 and a wire assembly 33. The bracket 31 is connected to the frame 10 and is located above the threading space 10a. The wire assembly 33 is arranged on the side of the bracket 31 away from the threading space 10a; wherein the bracket 31 is provided with a wire hole facing the threading space 10a, and the wire 301 led out from the wire assembly 33 passes through the wire hole and enters the threading space 10a.

[0068] In this embodiment, the rack 10 includes a mounting seat 11 and a mounting frame 13. The bracket 31 is connected to the mounting frame 13 and is arranged opposite to the mounting seat 11. The bracket 31 is used to provide structural support for the wire assembly 33 so that the wire assembly 33 can be located above the threading space 10a. The wire 301 passing through the wire hole can fall naturally, which is convenient for the transportation of the wire 301.

[0069] Further, refer to Figure 5 In one embodiment, the wire assembly 33 includes a wire rack 331, a tensioning member 333, at least one wire wheel 335 and a wire sleeve 337. The wire rack 331 is arranged on the bracket 31. The wire rack 331 is used to install the wire roller 300 wound with the wire 301. The tensioning member 333 is connected to the bracket 31. The tensioning member 333 is provided with a tensioning rod 3331 that can move along the gravity direction. The upper end of the tensioning rod 3331 is provided with a wire hole for the wire 301 to pass through; at least one wire wheel 335 is connected to the bracket 31 to change the direction of the wire 301 wound around at least one wire wheel 335. The wire sleeve 337 is arranged at the wire hole. The wire 301 passes through the wire hole, is wound around at least one wire wheel 335, and passes through the wire sleeve 337 and the wire hole in sequence to enter the threading space 10a.

[0070] In this embodiment, the bracket 31 includes a mounting platform 311 and a fixing plate 313. The mounting platform 311 is arranged on the frame 10, and the side of the fixing plate 313 is connected to the surface of the mounting platform 311 away from the frame 10. The wire rack 331 can be a columnar structure fixed to one side of the mounting platform 311. The wire roller 300 wound with the wire 301 is roughly cylindrical. The wire roller 300 can be directly sleeved on the wire rack 331. Preferably, the central axis of the wire rack 331 is vertically arranged to ensure the stability of the wire roller 300. Alternatively, the wire rack 331 can be connected to both ends of the wire roller 300, and the wire roller 300 can be rotatably arranged.

[0071] The tensioning member 333 also includes a fixed block, which is arranged on a surface of the fixed plate 313. The fixed block is provided with a through hole along the direction of gravity, and the tensioning rod 3331 is movably arranged in the through hole. A wire hole is provided at the upper end of the tensioning rod 3331. By adjusting the height of the tensioning rod 3331, a constraint is given to the wire 301 passing through the wire hole in the direction of gravity, so that it is tight and does not become loose and affect the wire effect. Optionally, a wire shaft can be provided between the tensioning member 333 and the wire roller 300 to fix the height of the wire 301 passing through the wire hole, avoid the wire 301 from getting stuck and ensure the effect of the tensioning member 333.

[0072] In one embodiment, three vertically arranged wire wheels 335 are provided on one side of the tensioning member 333. The wire 301 passes through each wire wheel 335 from top to bottom in turn and enters the wire sleeve 337. The wire hole is provided on the mounting platform 311. The wire sleeve 337 passes through the wire hole from one side of the mounting platform 311 to the other side to guide the wire 301 to the threading space 10a. The wire wheels 335 are provided so that the wire 301 changes direction or path after several windings, so that it has a certain structural support in space, further avoids wire jamming, and guides the wire 301 into the wire sleeve 337. Of course, the number and arrangement of the wire wheels 335 depend on the actual situation and are not limited here.

[0073] Reference Figure 1 , Figure 5 and Figure 6 In one embodiment, the wire feeding assembly 30 also includes a wire pulling assembly 35, which is disposed on the frame 10 and has a wire pulling clamp 351. The wire pulling clamp 351 is movably disposed under the bracket 31, and the wire pulling clamp 351 can clamp the wire 301 to guide the wire 301 from the wire hole to the threading space 10a.

[0074] In this embodiment, the wire pulling clamp 351 has no limit on the movement mode, but it can at least pass under the wire hole and the threading space 10a, wherein the wire pulling clamp 351 is provided with two clamping blocks that can move closer to or farther from each other, and the two clamping blocks can be driven by a cylinder or a motor, etc. That is to say, the wire pulling clamp 351 can clamp or release the wire 301 while moving.

[0075] Based on this, in one embodiment, the wire pulling jaw 351 can clamp the wire 301 near the wire hole and pull the wire 301 to the threading space 10a, and the wire pulling jaw 351 is released and moves to the vicinity of the wire hole again, and the above operation is repeated to pull the wire 301 of a specified length. In addition, when the wire 301 guided to the threading space 10a is located on one side of the hook 433, the wire pulling jaw 351 can clamp the wire 301 and guide it to the hook groove 433a of the hook 433.

[0076] Further, refer to Figure 6 In one embodiment, the wire pulling assembly 35 also includes a translation mechanism 352, a lifting mechanism 353 and a pushing mechanism 354. The translation mechanism 352 is connected to the frame 10, the lifting mechanism 353 is connected to the movable end of the translation mechanism 352, the pushing mechanism 354 is connected to the movable end of the lifting mechanism 353, the wire pulling clamp 351 is connected to the movable end of the pushing mechanism 354, and is arranged toward the threading space 10a. The translation mechanism 352, the lifting mechanism 353 and the pushing mechanism 354 are used to drive the wire pulling clamp 351 to move and pull the wire 301.

[0077] Commonly, the translation mechanism 352, the lifting mechanism 353 and the pushing mechanism 354 can be driven by an electric cylinder or a pneumatic cylinder. The translation mechanism 352 is provided with a translation plate, and the lifting mechanism 353 is provided on a surface of the translation plate; the lifting mechanism 353 is provided with a lifting frame, which is bent in an "L" shape, one of which is driven by the lifting mechanism 353, and the pushing mechanism 354 is provided on the other; the pushing mechanism 354 is provided with a pushing plate, and the wire pulling clamp 351 is provided on the pushing plate. In this way, the wire pulling clamp 351 is driven by the translation mechanism 352, the lifting mechanism 353 and the pushing mechanism 354 to move, and it has a high degree of freedom, and can realize diversified operations more flexibly. In one embodiment, even if the projections of the wire hole and the threading space 10a on the horizontal plane do not overlap or are slightly apart, the wire pulling clamp 351 can clamp the wire 301 to the threading space 10a, and make the hook 433 hook the wire 301, thereby improving the ease of use, practicality and automation of the device.

[0078] Reference Figure 1 , Figure 4 and Figure 8 In one embodiment, the automatic threading device 100 also includes a wire cutting assembly 50, which is disposed on the frame 10 and located above the threading space 10a. The wire cutting assembly 50 includes a wire cutting jaw 51 and a wire cutting piece 53. The wire cutting jaw 51 is movably arranged to approach or move away from the wire 301. The wire cutting jaw 51 is used to clamp or release the wire 301. The wire cutting piece 53 is movably arranged below the wire cutting jaw 51 to approach or move away from the wire 301. The wire cutting piece 53 is used to cut the wire 301.

[0079] Commonly, the wire cutting jaw 51 and the wire cutting member 53 are driven by a cylinder or an electric cylinder, and the driving member is connected to the frame 10. In this embodiment, the wire cutting jaw 51 includes two clamping arms 511 arranged in parallel, and the two clamping arms 511 can move closer to or farther from each other. Preferably, one of the clamping arms 511 is fixed, and the other clamping arm 511 moves relative to or away from it, so that the ends of the two clamping arms 511 are close to and abut against each other to clamp the wire 301, and move away from each other to release the wire 301. In order to save space and avoid affecting other components, the two clamping arms 511 are bent, and the distance between the ends of the clamping arms 511 and the wire cutting member 53 is shortened, so that the wire cutting member 53 can cut the wire 301 more conveniently.

[0080] Optionally, the wire cutting member 53 includes two blades that can move closer or farther away from each other, and the two blades move closer to each other and shear to cut the wire 301. It can be understood that the wire cutting member 53 and the wire cutting clamp 51 are driven independently, and the two can perform clamping or cutting operations independently.

[0081] Reference Figure 4 and Figure 7 In one embodiment, the automatic threading device 100 further includes a second guide member 70 and a third guide member 71. The second guide member 70 and the third guide member 71 are both disposed on the frame 10 and are relatively disposed on both sides of the threading space 10a. The second guide member 70 and the third guide member 71 cooperate to form a guide channel 72. The guide channel 72 passes through the threading space 10a and is used to thread the needle body so that the needle hole of the needle body is exposed in the threading space 10a.

[0082] In this embodiment, the second guide member 70 and the third guide member 71 may be a cylinder or a block, and the second guide member 70 and the third guide member 71 may be provided with through holes to form the above-mentioned guide channel 72; or, the second guide member 70 and the third guide member 71 may be partially curled to form a groove-shaped guide channel 72 extending along the length direction of the needle body 200 to support the needle body 200 or limit the needle body 200. It can be understood that when the needle body 200 is fixed and the threading operation is performed, the needle hole is set at the part of the guide channel 72 located in the threading space 10a, and when the needle body 200 and the automatic threading device 100 move relative to each other, the needle body 200 can move in the guide channel 72.

[0083] In addition, when the threading assembly 40 is provided with the first guide member 44, the first guide member 44 and the second guide member 70 can be an integral structure to improve the integrity of the structure.

[0084] In one embodiment, the automatic threading device 100 also includes a detection mechanism 60, which is disposed on the frame 10 and on one side of the threading space 10a to detect the position of the needle body 200. The detection mechanism 60 can be an in-position sensor, which interacts with the main controller of the automatic threading device 100 by signal after detecting the position of the needle body 200 to perform the next adjustment or threading operation.

[0085] Further, refer to Figures 1 to 4 The automatic threading device 100 also includes a moving mechanism 20. The frame 10 is connected to the moving mechanism 20. The moving mechanism 20 is used to drive the frame 10 to move so as to adjust the relative position of the threading assembly 40 and the needle body 200. On the one hand, before the threading operation begins, the relative position of the two can be adjusted by the moving mechanism 20 so that the needle hole is located at a specified position of the threading space 10a; on the other hand, the hook 433 hooks the wire 301 and drives the wire 301 to pass through the needle hole. At this time, the wire 301 in the needle hole is in the form of a double-strand wire. By adjusting the moving mechanism 20, the hook 433 can be moved relative to the needle body 200 and pull the wire 301 to make it a single-strand wire.

[0086] Optionally, the moving mechanism 20 may be an electric cylinder or a pneumatic cylinder mechanism provided with a guide rail, and the frame 10 is connected to a movable end of the moving mechanism 20 .

[0087] Refer again Figures 1 to 8 In one embodiment, the automatic threading device 100 includes a wire feeding assembly 30, a wire cutting assembly 50 and a threading assembly 40 arranged on a frame 10, wherein the frame 10 is connected to a moving mechanism 20 and is connected to a detection mechanism 60, and the wire feeding assembly 30 includes a wire assembly 33 and a wire pulling assembly 35. The automatic threading device 100 detects the position of the needle body 200 through the detection mechanism 60, and realizes the overall movement of the frame 10 through the moving mechanism 20 to adjust the relative position relationship between the wire feeding assembly 30, the wire cutting assembly 50 and the threading assembly 40 and the needle body 200, so that the needle body 200 is set at a specified position in the threading space 10a, and the specified position can be the position where the needle hole is close to the second guide member 70, the first guide member 44 and the second guide member 70 are an integrated mechanism, and the unopened side of the hook 433 is located in the guide groove 44a.

[0088] The wire 301 passes through the wire hole from the wire assembly 33, and its initial end is clamped by the wire cutting assembly 50. The wire pulling assembly 35 then moves to the side of the wire cutting assembly 50 and clamps the wire end. After that, the wire cutting assembly 50 releases and moves away from the wire 301 to avoid the wire pulling assembly 35. The wire pulling assembly 35 sends the wire 301 to the hook 433 that has previously passed through the needle hole and is waiting in the threading space 10a, and guides the wire 301 into the hook groove 433a. The wire pulling assembly 35 releases the wire 301, and the hook 433 pulls the wire 301 with its own movement until it passes through the needle hole. The moving mechanism 20 drives the frame 10 to move as a whole relative to the needle body 200 to pull the double-strand wire hooked into the needle hole into a single-strand wire, and then the wire pulling assembly 35 clamps the wire 301 again and pulls the wire 301 from the wire hole toward the threading space 10a, and repeats this cycle several times to pull the wire 301 to the required size, and then the wire cutting assembly 50 moves to clamp the wire 301 and cuts the wire 301.

[0089] Such a cycle can continuously perform the threading operation of the needle body 200, realize the automation of the needle body threading, and improve the assembly efficiency compared with the traditional manual threading.
