[0032] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] Example:

[0034] Combine Figures 3 to 10 The present invention shows a specific embodiment of a strap threading mechanism, referring to Figure 3 It mainly includes a turntable 1, on which a fixing seat 2 for placing a watch strap a is provided. Figure 4The mounting base 2 includes a mounting body 201 and a retaining clip 202 mounted on the mounting body 201 via a spring. To place a watchband a, the retaining clip 202 is pushed inward, placing the watchband a on the mounting body 201. The retaining clip 202 is then released, and the spring forces the retaining clip 202 to clamp the watchband a. A wire clamp 3 is provided at the end of the mounting body 201 of the mounting base 2. The upper end of the wire clamp 3 has two spaced-apart wire-gripping portions 3a for respectively clamping two wire ends.

[0035] One side of the turntable 1 is provided with a flattening mechanism 4, a wire feeding machine 5, a gripper robot 6, and a threading machine 7. Figure 5 The flattening mechanism 4 includes a first X-axis module 401, a first Z-axis module 402 connected to the first X-axis module 401, and a pressure rod 403 connected to the first Z-axis module 402. The pressure rod 403 extends perpendicular to the fixing base 2. After the watchband a is placed on the fixing base 2, the pressure rod 403 is moved by the first X-axis module 401 and the first Z-axis module 402 to press the watchband a, thereby preventing it from moving.

[0036] Reference Figure 6 The wire feeding machine 5 includes a wire feeding device 501, a first threading seat 502, a wire clamping device 503, a second threading seat 504, and a wire cutting device 505, which are sequentially arranged. The wire b provided by the wire feeding device 501 passes through the first threading seat 502, the wire clamping device 503, and the second threading seat 504 in sequence. The wire clamping device 503 includes a wire clamping claw 503b driven by a wire clamping cylinder 503a, which can clamp the wire b. The wire cutting device 505 includes a scissors mounted on the front end of the second threading seat 504, which can be raised to cut the wire b.

[0037] The wire feeding machine 5 is used to provide the wire b for the gripper robot 6 to pull. Figure 7 The gripper robot 6 includes a robot body 601, a robot gripper assembly 603 connected to the robot body 601 and driven by a rotary cylinder 602, and the robot gripper assembly 603 can clamp the thread end and cooperate with the threading machine 7 to perform the threading action.

[0038] Reference Figure 8 The threading machine 7 includes a hook assembly 701 and a thread clamp assembly 702. The hook assembly 701 includes a second X-axis module 701a, a Y-axis module 701b connected to the second X-axis module 701a, a second Z-axis module 701c connected to the Y-axis module 701b, and a hook 701d connected to the second Z-axis module 701c. Figure 9The top of hook 701d has a hook hole 8. When hooking, hook 701d passes through the threading hole a0 of watchband a. The wire b pulled by gripper robot 6 passes around the hook hole 8 of hook 701d. Driven by the module, hook 701d pulls the wire b downward through the threading hole a0 and pulls the thread end to the bottom of watchband a.

[0039] The wire clamping assembly 702 includes a wire clamping claw assembly 702b connected to the Y-axis module 701b and driven by a lifting cylinder 702a. The wire clamping claw assembly 702b is located below the fixed base 2. After the hook assembly 701 completes a downward hooking action, the wire clamping claw assembly 702b clamps the wire b. The lifting cylinder 702a drives the wire clamping claw assembly 702b to descend, continuing to pull the wire b down. At the same time, a distance is reserved between the wire clamping claw assembly 702b and the fixed base 2. The gripper robot 6 can extend between the wire clamping claw assembly 702b and the fixed base 2, and continue to pull the wire b and hook it onto the hook assembly 701.

[0040] When the watch strap threading mechanism of the present invention is in operation, the watch strap a is placed on the fixing seat 2 and fixed with the fixing clamp 202, and then the watch strap a is pressed by the pressure rod 403 of the flattening mechanism 4 to prevent the watch strap a from moving. The hook 701d on the threading machine 7 passes through the threading hole a0 of the watch strap a, and the gripper robot 6 grips the end of the wire b from the wire feeding machine 5 and passes it around the hook hole 8 of the hook 701d. The module drives the hook 701d and the wire to move downward, passes the wire through the threading hole a0 of the watch strap a, and pulls the end of the wire to the bottom of the watch strap a. Then the wire clamping claw assembly 702b grips the wire b, and the lifting cylinder 702a drives the wire clamping claw assembly 702b and the wire to move downward, and reserves a distance between the wire clamping claw assembly 702b and the fixing seat 2, and then the gripper robot 6 extends to the wire clamping claw assembly 70 2b and the fixed seat 2, holding the thread end and continuing to pass it around the hook 701d. After repeating the threading action several times, the threading is completed. At this time, the thread end is clamped by the wire clamping claw assembly 702b. The claw robot 6 first clamps the wire b led by the wire feeder 5. The scissors of the wire feeder 5 rise and cut the wire b to break the wire. The claw robot 6 then clamps the thread end at this end into one of the clamping parts 3a of the wire clamp 3. It then extends between the wire clamping claw assembly 702b and the fixed seat 2, clamps the thread end at the other end into the other clamping part 3a of the wire clamp 3, and completes the entire threading action. Finally, the pressure rod 403 of the flattening mechanism 4 is lifted, releasing the watchband a. The threaded watchband a rotates with the turntable 1 to the next station for the next process.
