Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing, and in particular to a detection device for taking threaded sleeves. Background Technology

[0002] In modern automotive manufacturing, lightweight and high-strength design have become important trends. With the widespread use of lightweight materials such as aluminum alloys and composite materials, traditional threaded connections face challenges. This is because lightweight materials themselves have lower thread strength, making them prone to thread stripping, deformation, or fatigue failure under high loads, leading to loose connections. In particular, critical automotive components (such as engine blocks) need to withstand vibration, temperature changes, and dynamic loads, placing higher demands on the reliability and durability of threaded connections. Therefore, during the production of automotive parts, wire thread inserts are pre-screwed into the holes of the automotive parts. The wire thread inserts have internal and external threads. The external thread of the wire thread insert mates with the hole thread of the automotive part, while the internal thread of the wire thread insert mates with the bolt thread to enhance the connection strength of the automotive parts.

[0003] When the spiral coil of a wire thread insert is wound, its two ends are usually asymmetrically set. One end of the wire thread insert is usually designed with a protruding end extending towards the center. During installation, one end of the wire thread insert needs to be screwed into the hole of the automotive part, so that the protruding end is located at the deepest point of the hole. This allows the protruding end to limit the screwing depth when the bolt is screwed into the wire thread insert. However, currently, the orientation of the wire thread insert needs to be manually identified, and manual identification is inefficient and cannot be adapted to the automated processing of automotive parts. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a detection device for threaded insert material handling. The purpose is to solve the problem that wire threaded inserts typically have a protruding end extending towards the center. During installation, one end of the wire threaded insert needs to be screwed into a hole in the automotive part, with the protruding end positioned at the deepest point of the hole. This allows the protruding end to limit the screw-in depth when the bolt is screwed into the wire threaded insert. However, currently, the orientation of the wire threaded insert requires manual identification, which is inefficient and cannot be adapted to the automated processing of automotive parts.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A detection device for picking up wire thread inserts includes a worktable. A feeding mechanism is provided on the top of the worktable for conveying wire thread inserts. A grabbing mechanism and a detection mechanism are also provided on the top of the worktable. The grabbing mechanism grabs the wire thread inserts to the detection mechanism. The detection mechanism includes a detection support frame on the top of the worktable. A detection seat is provided on one side of the detection support frame. A movable groove is formed inside the detection seat, extending through the top and bottom of the detection seat. A detection slide rod is slidably connected inside the movable groove. One side of the detection slide rod... The detection rod is provided with a detection end, which extends through one end of the movable groove and is located at the top of the detection seat. The detection end is used for the installation of a wire thread sleeve, and the size of the detection end is smaller than the inner diameter of the wire thread sleeve. The other end of the detection slide rod is provided with a linkage end, which extends through the other end of the movable groove and is located at the bottom of the detection seat. A micro switch is provided on one side of the detection support frame, which is located below the detection seat. The top of the micro switch is provided with a flexible micro spring, which abuts against the linkage end.

[0007] When the wire thread insert is picked up from the feeding mechanism by the material-catching mechanism and placed on the detection end, if the protruding end of the wire thread insert faces upward, the wire thread insert will not contact the detection end during placement because the size of the detection end is smaller than the inner diameter of the wire thread insert. The detection slide rod remains in its initial position due to the lack of external force, and the linkage end does not apply any force to the micro-motion spring. The micro switch is in the open state, thus the wire thread insert's orientation is correctly determined. If the protruding end of the wire thread insert faces downward, it will contact the detection end under the action of the material-catching mechanism. The detection end then drives the detection slide rod to slide along the movable groove, causing the linkage end to press down on the micro-motion spring and trigger the micro switch. This facilitates the reception of non-conforming signals through the existing PLC system, enabling the identification of incorrect wire thread insert settings, improving the wire thread insert recognition efficiency, and better adapting to the automated processing of automotive parts.

[0008] Furthermore, in this application, the detection mechanism includes a tail detection seat located on the top of the detection support frame. An extension seat is provided on one side of the tail detection seat. An installation hole is provided inside the extension seat, and the installation hole extends through the top and bottom of the extension seat. A proximity switch is installed inside the installation hole, and the detection end of the proximity switch is close to the top of the extension seat.

[0009] When the material-catching mechanism picks up the wire thread insert from the discharge mechanism, it first picks up the wire thread insert above the tail detection seat and rotates it to a horizontal position. If the wire thread insert is wrapped with excess wire thread insert, the excess wire thread insert will protrude above the extension seat, allowing the proximity switch to detect the proximity of the excess wire thread insert. This facilitates the transmission of an abnormal signal to the existing PLC system for receiving and identifying the situation where the wire thread insert is wrapped with excess wire thread insert. If the wire thread insert is not wrapped with an adjacent wire thread insert, the original length of the wire thread insert is insufficient to extend above the extension seat, and therefore it will not be detected by the proximity switch.

[0010] Furthermore, in this application, the bottom of the linkage end is provided with a limiting bottom block, the size of which is larger than the size of the movable groove, and the micro-motion spring abuts against the limiting bottom block.

[0011] When the wire thread sleeve is removed, the micro-motion spring will reset due to its elasticity, thereby driving the linkage end to return to its original position. Since the size of the limit block is larger than the size of the movable slot, it avoids the linkage end from penetrating too much into the movable slot when resetting, thus affecting the triggering of the linkage end next time.

[0012] Furthermore, in this application, one end of the detection end is provided with a guide end, which is in the shape of a cone.

[0013] Furthermore, in this application, the material-catching mechanism includes a material-catching connecting seat, which is movably disposed on the top of the workbench. A material-catching rotating seat is rotatably connected to one side of the material-catching connecting seat, and a material-catching rotating motor for driving the material-catching rotating seat is provided on the other side of the material-catching connecting seat. A material-catching pneumatic gripper is provided on one side of the material-catching rotating seat, and two gripper ends are provided on one side of the material-catching pneumatic gripper. The two gripper ends are spaced apart to form a clamping interval, and the material-catching pneumatic gripper drives the two gripper ends to clamp.

[0014] Furthermore, in this application, a clamping opening is provided on one side of the gripper end, the clamping opening is connected to the clamping interval, and the clamping opening is arc-shaped.

[0015] Furthermore, in this application, the material-catching mechanism includes a material-catching support frame disposed on the top of the workbench. A material-catching moving frame is provided laterally on one side of the material-catching support frame. A material-catching moving cavity is opened on one side of the material-catching moving cavity. A material-catching transmission screw is rotatably connected inside the material-catching moving cavity. A material-catching moving motor is provided on the other side of the material-catching moving frame. The material-catching moving motor drives the material-catching transmission screw to rotate. A material-catching moving nut is sleeved on the outside of the material-catching transmission screw. A first material-catching moving seat is provided on one side of the material-catching moving nut. A material-catching lifting frame is vertically disposed on one side of the first material-catching moving seat. A material-catching lifting cavity is opened on one side of the material-catching lifting frame. A material-catching lifting screw is rotatably connected inside the material-catching lifting cavity. A material-catching lifting motor is provided on the other side of the material-catching lifting frame. The material-catching lifting motor drives the material-catching lifting screw to rotate. A material-catching lifting nut is sleeved on the outside of the material-catching lifting screw. A second material-catching moving seat is provided on one side of the material-catching lifting nut. A material-catching connecting seat is disposed on one side of the second material-catching moving seat.

[0016] Furthermore, in this application, the feeding mechanism includes a feeding seat located on the top of the workbench. The top of the feeding seat has a feeding port, and one side of the feeding seat has a connecting groove. A lifting cylinder is vertically mounted on the top of the workbench. One end of the lifting cylinder has a lifting connecting block, and the top of the lifting connecting block has a feeding frame. One end of the feeding frame passes through the connecting groove, and the top of the feeding frame has a feeding channel that connects to the feeding port. The other end of the feeding frame has a discharge port that connects to the feeding channel. A vibrating feeding motor is mounted on one side of the feeding frame, and the vibrating feeding motor drives the feeding frame to vibrate.

[0017] Furthermore, in this application, the top of the workbench is provided with an adjusting cylinder, one end of the adjusting cylinder is provided with an identification movable seat, the top of the identification movable seat is provided with an identification mounting frame, the top of the identification mounting frame is provided with a distance sensor, and the identification end of the distance sensor faces the discharge port.

[0018] Furthermore, in this application, the feeding mechanism includes a feeding moving frame horizontally disposed on the top of the workbench. A feeding moving cavity is provided on one side of the feeding moving frame. A feeding transmission screw is rotatably connected inside the feeding moving cavity. A feeding moving motor is provided on the other side of the feeding moving frame. The feeding moving motor drives the feeding transmission screw to rotate. A feeding moving nut is sleeved on the outside of the feeding transmission screw. A feeding movable plate is provided on the top of the feeding moving nut. The feeding seat is disposed on the top of the feeding movable plate.

[0019] This utility model has the following beneficial effects:

[0020] When the wire thread insert is placed on the detection end by the material-catching mechanism, the mechanism catches the insert and places it on the detection end. If the protruding end of the insert faces upward, the insert will not contact the detection end because the size of the detection end is smaller than the inner diameter of the insert. The detection slide bar remains in its initial position without external force, and the linkage end does not apply any force to the micro-motion spring. The micro switch is in the open state, thus the insertion direction of the wire thread insert is correctly determined. If the protruding end faces downward, it will contact the detection end. The detection end then drives the detection slide bar to slide along the movable groove, causing the linkage end to press down on the micro-motion spring and trigger the micro switch. This allows the faulty signal to be received by the existing PLC system, facilitating the identification of incorrect wire thread insert settings, improving the identification efficiency, and better adapting to the automated processing of automotive parts.

[0036] Reference Figures 1-10In some specific embodiments, a detection device for picking up wire thread inserts includes a workbench 10. A feeding mechanism 20 is provided on the top of the workbench 10 for conveying wire thread inserts 11. A grabbing mechanism 30 and a detection mechanism 40 are also provided on the top of the workbench 10. The grabbing mechanism 30 grabs the wire thread insert 11 to the detection mechanism 40. The detection mechanism 40 includes a detection support frame 41 located on the top of the workbench 10. A detection seat 413 is provided on one side of the detection support frame 41. A movable groove 414 is formed inside the detection seat 413, extending through the top and bottom of the detection seat 413. A detection slide rod 415 is slidably connected inside the movable groove 414. One end of the detection slide bar 415 is provided with a detection end 418, which extends through one end of the movable groove 414 and is located at the top of the detection seat 413. The detection end 418 is used to fit the wire thread sleeve 11. The size of the detection end 418 is smaller than the inner diameter of the wire thread sleeve 11. The other end of the detection slide bar 415 is provided with a linkage end 419, which extends through the other end of the movable groove 414 and is located at the bottom of the detection seat 413. A micro switch 411 is provided on one side of the detection support frame 41. The micro switch 411 is located below the detection seat 413. The top of the micro switch 411 is provided with a flexible micro spring 412, which abuts against the linkage end 419.

[0037] Through the above technical solution, when the wire thread insert 11 is picked up from the feeding mechanism 20 by the material-catching mechanism 30 and placed on the detection end 418, the material-catching mechanism 30 picks up the wire thread insert 11 and places it on the detection end 418. If the protruding end 12 of the wire thread insert 11 faces upward, since the size of the detection end 418 is smaller than the inner diameter of the wire thread insert 11, the wire thread insert 11 will not contact the detection end 418 when it is placed. The detection slide rod 415 remains in its initial position because there is no external force pushing it. The linkage end 419 does not apply a pushing force to the micro switch 412, and the micro switch 411 is in the open state. Therefore, the setting direction of the wire thread insert 11 is judged to be correct. If the protruding end 12 of the wire thread insert 11 faces downward, the protruding end 12 will contact the detection end 418 under the drive of the material handling mechanism 30. Then, the detection end 418 drives the detection slide bar 415 to slide along the movable groove 414, so that the linkage end 419 presses down the micro switch 412 to trigger the micro switch 411. This makes it easier to receive the unqualified signal through the existing PLC system, so as to identify the incorrect setting of the wire thread insert 11, improve the identification efficiency of the wire thread insert 11, and better adapt to the automated processing of automotive parts.

[0038] It should be noted that the length of the detection end 418 matches the depth of the wire thread insert 11, so that when the wire thread insert 11 is inserted into the detection end 418 in the forward direction, the detection end 418 cannot touch the protruding end 12 of the wire thread insert 11.

[0039] In addition, when the linkage end 419 presses down the micro switch 412 to trigger the micro switch 411, the unqualified signal can be received by the existing PLC system and the wire thread sleeve 11 with the wrong direction can be rejected by the existing defective product sorting mechanism, thereby further improving the sorting efficiency of the wire thread sleeve 11; or a buzzer or alarm can be set above the workbench 10. When the unqualified signal is received by the existing PLC system, the PLC system will control the buzzer or alarm to give a warning, so as to remind the operator of the abnormal situation of the wire thread sleeve 11 and facilitate the operator to handle the abnormal situation.

[0040] In another embodiment, when the wire thread insert 11 is caught by the material-catching mechanism 30 and reaches the detection end 418, if the protruding end 12 faces downwards, it will contact the detection end 418. The detection end 418 then drives the detection slide rod 415 to slide along the movable groove 414, causing the linkage end 419 to press down the micro-motion spring 412 and trigger the micro switch 411, thus determining that the direction of the wire thread insert 11 is correct. If the protruding end 12 faces upwards, the detection end 418 cannot be triggered, therefore the direction of the wire thread insert 11 is determined to be incorrect. However, in actual production, the wire thread insert 11 is in the positive direction (i.e., the steel thread insert 11 is in the positive direction). The number of wire thread inserts 11 with the protruding end facing down is greater than the number with the reverse side. Therefore, this method triggers the micro switch 411 more times, making the micro switch 411 prone to failure under high-intensity use. Therefore, the preferred solution is that the protruding end 12 faces up. However, after this solution is connected to an external screw-in device, the wire thread insert 11 needs to be rotated 180 degrees by the material-catching mechanism 30 so that the protruding end 12 of the wire thread insert 11 faces down. Then, the wire thread insert 11 is loaded onto the screw-in device so that the protruding end 12 of the wire thread insert 11 can be screwed into the deepest hole of the automotive part.

[0041] Reference Figures 6-7 In some specific embodiments, the detection mechanism 40 includes a tail detection seat 423 located on the top of the detection support frame 41. An extension seat 42 is provided on one side of the tail detection seat 423. An installation hole 422 is provided inside the extension seat 42. The installation hole 422 passes through the top and bottom of the extension seat 42. A proximity switch 421 is installed inside the installation hole 422. The detection end 418 of the proximity switch 421 is close to the top of the extension seat 42.

[0042] During the discharge process of the wire thread insert 11, due to the characteristics of the spiral structure of the wire thread insert 11, adjacent wire thread inserts 11 may be mechanically interlocked and entangled, forming an extra tail that is conveyed along with it. This kind of abnormality will not only affect the contact between the wire thread insert 11 and the detection end 418, but will also prevent the subsequent screwing in of the wire thread insert 11.

[0043] With the above technical solution, when the material-catching mechanism 30 catches the wire thread sleeve 11 from the discharge mechanism, the material-catching mechanism 30 first catches the wire thread sleeve 11 above the tail detection seat 423 and rotates the wire thread sleeve 11 to a horizontal position. If the wire thread sleeve 11 is wrapped with excess wire thread sleeve 11, the excess wire thread sleeve 11 will protrude above the extension seat 42, so that the proximity switch 421 can detect the excess wire thread sleeve 11 approaching, thereby facilitating the transmission of an abnormal signal to the existing PLC system for reception, so as to identify the situation where the wire thread sleeve 11 has excess wire thread sleeve 11 wrapped. If the wire thread sleeve 11 is not wrapped with the adjacent wire thread sleeve 11, the original length of the wire thread sleeve 11 is insufficient to extend above the extension seat 42, so it will not be detected by the proximity switch 421.

[0044] In addition, when the proximity switch 421 detects that an extra wire thread sleeve 11 is approaching, the abnormal signal is received by the existing PLC system, and the defective product sorting mechanism removes the wire thread sleeve 11 with the extra wire thread sleeve, thereby further improving the sorting efficiency of the wire thread sleeve 11; or a buzzer or alarm is set above the workbench 10, and when the abnormal signal is received by the existing PLC system, the PLC system will control the buzzer or alarm to issue a warning, so as to remind the abnormal situation of the wire thread sleeve 11.

[0045] Reference Figures 6-7 In some specific embodiments, the bottom of the linkage end 419 is provided with a limiting bottom block 416, the size of the limiting bottom block 416 is larger than the size of the movable groove 414, and the micro-motion spring 412 abuts against the limiting bottom block 416.

[0046] With the above technical solution, when the wire thread sleeve 11 is removed, the micro-motion spring 412 will reset due to its elasticity, thereby driving the linkage end 419 to return to its original position. Since the size of the limiting bottom block 416 is larger than the size of the movable groove 414, it avoids the linkage end 419 from penetrating too much into the movable groove 414 when resetting, thus affecting the triggering of the linkage end 419 next time.

[0047] Reference Figures 6-7 In some specific embodiments, one end of the detection end 418 is provided with a guide end 417, which is in the shape of a cone.

[0048] With the above technical solution, when the material handling mechanism 30 puts the wire thread sleeve 11 onto the detection end 418, if the insertion position of the wire thread sleeve 11 deviates by millimeters from the guide end 417, the inclined surface of the cone of the guide end 417 will make short-term contact with the inner wall of the wire thread sleeve 11. The shape of the cone will guide the insertion position of the wire thread sleeve 11 to ensure that the insertion direction of the wire thread sleeve 11 is correct.

[0049] It should be noted that if the insertion position of the wire thread insert 11 deviates from the guide end 417 by millimeters (if it exceeds the millimeter level, the placement position of the material handling mechanism 30 needs to be recalibrated), the inclined surface of the cone of the guide end 417 will briefly contact the inner wall of the wire thread insert 11. However, since the contact time is short and the contact position of the wire thread insert 11 is the outer edge of the guide end 417, the detection end 418 will not drive the linkage end 419 to produce a large displacement. Therefore, the displacement distance of the linkage end 419 is significantly different from the displacement distance triggered by the protrusion end 12 of the wire thread insert 11. To avoid the micro switch 411 misidentifying this type of problem, the sensitivity of the micro switch 411 can be reduced. In addition, the displacement distance of the linkage end 419 can be further reduced by increasing the friction between the detection slide bar 415 and the movable groove 414.

[0050] Reference Figures 1-6 In some specific embodiments, the material-catching mechanism 30 includes a material-catching connecting seat 34, which is movably disposed on the top of the workbench 10. A material-catching rotating seat 342 is rotatably connected to one side of the material-catching connecting seat 34, and a material-catching rotating motor 341 for driving the material-catching rotating seat 342 is provided on the other side of the material-catching connecting seat 34. A material-catching pneumatic gripper 343 is provided on one side of the material-catching pneumatic gripper 343, and two gripper ends 344 are provided on one side of the material-catching pneumatic gripper 343. The two gripper ends 344 are separated to form a clamping interval 346, and the material-catching pneumatic gripper 343 drives the two gripper ends 344 to clamp.

[0051] With the above technical solution, when the material grabbing mechanism 30 grabs the wire thread sleeve 11, the two gripper ends 344 of the material grabbing pneumatic gripper 343 clamp the wire thread sleeve 11 of the feeding mechanism 20. The material grabbing rotating seat 342 is driven to rotate by the rotary motor, thereby adjusting the direction of the wire thread sleeve 11 so as to facilitate forward and reverse detection or more winding detection of the wire thread sleeve 11.

[0052] Reference Figures 1-6 In some specific embodiments, a clamping opening 345 is provided on one side of the gripper end 344, the clamping opening 345 is connected to the clamping interval 346, and the clamping opening 345 is arc-shaped.

[0053] With the above technical solution, when the two gripper ends 344 of the material-catching pneumatic gripper 343 clamp the wire thread sleeve 11 of the feeding mechanism 20, the wire thread sleeve 11 will be located in the clamping opening 345 of the two gripper ends 344, thereby increasing the contact area between the wire thread sleeve 11 and the gripper ends 344 and improving the stability of the wire thread sleeve 11 during clamping.

[0054] Reference Figures 1-4In some specific embodiments, the material-catching mechanism 30 includes a material-catching support frame 31 disposed on the top of the workbench 10. A material-catching moving frame 32 is laterally disposed on one side of the material-catching support frame 31. A material-catching moving cavity 321 is opened on one side of the material-catching moving cavity 321. A material-catching transmission screw 322 is rotatably connected inside the material-catching moving cavity 321. A material-catching moving motor 323 is disposed on the other side of the material-catching moving frame 32. The material-catching moving motor 323 drives the material-catching transmission screw 322 to rotate. A material-catching moving nut 324 is sleeved on the outside of the material-catching transmission screw 322. A first material-catching moving nut 324 is disposed on one side of the material-catching moving nut 324. The first material-catching moving seat 330 has a material-catching lifting frame 331 vertically mounted on one side. A material-catching lifting cavity 336 is opened on one side of the material-catching lifting frame 331. A material-catching lifting screw 332 is rotatably connected inside the material-catching lifting cavity 336. A material-catching lifting motor 333 is mounted on the other side of the material-catching lifting frame 331. The material-catching lifting motor 333 drives the material-catching lifting screw 332 to rotate. A material-catching lifting nut 334 is sleeved on the outside of the material-catching lifting screw 332. A second material-catching moving seat 335 is mounted on one side of the material-catching lifting nut 334. A material-catching connecting seat 34 is located on one side of the second material-catching moving seat 335.

[0055] Through the above technical solution, the material-catching moving motor 323 drives the material-catching transmission screw 322 to rotate, and the material-catching moving nut 324 converts the rotational motion into linear motion, causing the first material-catching moving seat 330 to move laterally along the material-catching moving frame 32. Meanwhile, the material-catching lifting motor 333 drives the material-catching lifting screw 332 to rotate, and the material-catching lifting nut 334 converts the rotational motion into linear motion, causing the second material-catching moving seat 335 to move vertically along the material-catching lifting frame 331, thereby facilitating the adjustment of the material-catching position.

[0056] Reference Figures 1-9 In some specific embodiments, the feeding mechanism 20 includes a feeding seat 221 located on the top of the workbench 10. The top of the feeding seat 221 has a feeding port 222, and one side of the feeding seat 221 has a connecting groove 226. The top of the workbench 10 is vertically provided with a lifting cylinder 230. One end of the lifting cylinder 230 is provided with a lifting connecting block 231. The top of the lifting connecting block 231 is provided with a feeding rack 224. One end of the feeding rack 224 passes through the connecting groove 226. The top of the feeding rack 224 is provided with a feeding channel 225, which connects to the feeding port 222. The other end of the feeding rack 224 has a discharge port 227 that connects to the feeding channel 225. One side of the feeding rack 224 is provided with a vibrating feeding motor 223, which drives the feeding rack 224 to vibrate.

[0057] With the above technical solution, when the vibrating feed motor 223 is started, the vibrating feed motor 223 will drive the feeding frame 224 to vibrate. This vibration causes the wire thread sleeve 11 to move along the discharge port 227 (existing technology, so it will not be discussed in detail), thereby conveying the wire thread sleeve 11. If the position of the material grabbing mechanism 30 is too high or too low, the lifting cylinder 230 will push the feeding frame 224 to rise or fall, ensuring that the wire thread sleeve 11 is accurately delivered to the grabbing position.

[0058] Reference Figures 1-9 In some specific embodiments, the top of the workbench 10 is provided with an adjusting cylinder 243, one end of the adjusting cylinder 243 is provided with an identification movable seat 240, the top of the identification movable seat 240 is provided with an identification mounting bracket 241, the top of the identification mounting bracket 241 is provided with a distance sensor 242, and the identification end of the distance sensor 242 faces the discharge port 227.

[0059] With the above technical solution, when the wire thread sleeve 11 moves to the discharge port 227, since the recognition end of the distance sensor 242 is facing the discharge port 227, when the distance sensor 242 recognizes that the wire thread sleeve 11 is approaching, it will generate a proximity signal. After receiving the proximity signal through the existing PLC system, it controls the material grabbing mechanism 30 to grab the wire thread sleeve 11 at the discharge port 227, thereby improving the grabbing efficiency.

[0060] Reference Figures 1-9 In some specific embodiments, the feeding mechanism 20 includes a feeding moving frame 21 horizontally disposed on the top of the workbench 10. A feeding moving cavity 211 is provided on one side of the feeding moving frame 21. A feeding transmission screw 212 is rotatably connected inside the feeding moving cavity 211. A feeding moving motor 213 is provided on the other side of the feeding moving frame 21. The feeding moving motor 213 drives the feeding transmission screw 212 to rotate. A feeding moving nut 214 is sleeved on the outside of the feeding transmission screw 212. A feeding movable plate 220 is provided on the top of the feeding moving nut 214. A feeding seat 221 is provided on the top of the feeding movable plate 220.

[0061] Through the above technical solution, the feeding moving motor 213 drives the feeding transmission screw 212 to rotate, and the feeding moving nut 214 converts the rotational motion into linear motion, thereby driving the feeding movable plate 220 to adjust its position so that the wire thread sleeve 11 can grab it.
