[0023] The fiber optic heat shrink tubing mechanism of this utility model embodiment is described in detail below with reference to the accompanying drawings.

[0024] Reference Figure 1 and Figure 2As shown, the fiber optic heat shrink tubing 70 mechanism provided in this embodiment includes: a base frame 10, a tubing feeding assembly 20, a heat shrink assembly 30, a wire clamping assembly 40, and a guide assembly 50. The base frame 10 is equipped with a linear feeder 11 for conveying the heat shrink tubing 70. The linear feeder 11 mainly conveys the material from the beginning to the end by vibration or electric means. The beginning end is usually equipped with a vibratory feeder to allow material entry; for example, a YQ-80T electromagnetic linear vibratory feeder from Yeqin Company can be used. The tubing feeding assembly 20 is located at the end of the linear feeder 11 and is used to insert and rotate the heat shrink tubing 70 through the linear feeder 11. The heat shrink assembly 30 is positioned above the tube feeding assembly 20 and is movable between a first position and a second position. When the heat shrink assembly 30 moves to the first position, it is positioned above the tube feeding assembly 20 to clamp the heat shrink tube 70 away from the tube feeding assembly 20. The wire clamping assembly 40 is spaced apart and opposite to the base frame 10. When the heat shrink assembly 30 moves to the second position, the wire clamping assembly 40 clamps the optical fiber 60 and moves it below the heat shrink assembly 30. The guide assembly 50 is positioned below the heat shrink assembly 30 so that the wire clamping assembly 40 passes the optical fiber 60 through the guide assembly 50 and forces the heat shrink assembly 30 to sleeve the heat shrink tube 70 on the optical fiber 60.

[0025] Reference Figure 3 As shown, the tube feeding assembly 20 includes: a rotary cylinder 21, a fixed base 22, and a tube insertion component 23. The rotary cylinder 21 is mounted on the base frame 10, and the fixed base 22 is mounted on the rotary cylinder 21 and rotates with the rotary cylinder 21. The tube insertion component 23 is mounted on the fixed base 22 and can be driven by the rotary cylinder 21 to rotate the fixed base 22, so that the tube insertion component 23 rotates with the fixed base 22 and deflects to be aligned with the track of the linear feeder 11, so that the heat shrink tubing 70 is vibrated and inserted into the tube insertion component 23 from the track of the linear feeder 11. Since the tube insertion component 23 is composed of a fixed section 231 and a conical section 232 connected in one piece, the fixed section 23... 1. Fixed to the fixed base 22, the conical section 232 extends from the fixed section 231 onto the fixed base 22, so that when the tube insert 23 is deflected to be in the same straight line as the track of the linear feeder 11, the conical section 232 faces the heat shrink tube 70, so that when the heat shrink tube 70 is vibrated and conveyed, it can be inserted into the tube insert 23 through the conical section 232, making the insertion of the heat shrink tube 70 simpler and more accurate. After the heat shrink tube 70 is inserted into the tube insert 23, the rotary cylinder 21 drives the fixed base 22 to rotate away from the linear feeder 11, so that the tube insert 23 drives the heat shrink tube 70 to deflect upward, ensuring that the heat shrink tube 70 will not fall off the tube insert 23.

[0026] Reference Figure 4As shown, the heat shrink assembly 30 includes: a first linear module 31, a first cylinder 32, a first pneumatic gripper 33, a first heat shrink block 34, and a second heat shrink block 35. The first linear module 31 is mounted on the base frame 10 and is a lead screw module, for example, a Thomson M55 lead screw guide. The first cylinder 32 is mounted on the linear module and can move along the length of the linear module to a first position or a second position. The first position is directly above the tube fitting 23. A pneumatic gripper 33 is mounted on a first cylinder 32 and driven by the first cylinder 32 to move vertically. A first heat shrink block 34 is mounted on one gripper finger of the first pneumatic gripper 33, and a second heat shrink block 35 is mounted on the other gripper finger of the first pneumatic gripper 33. Under the drive of the first pneumatic gripper 33, the first heat shrink block 34 and the second heat shrink block 35 can be separated from or joined together. Optionally, the first pneumatic gripper 33 is a parallel gripper, such as the MPG-plus series pneumatic gripper from Schunk Corporation.

[0027] In this embodiment, when the tube insert 23 causes the heat shrink tubing 70 to deflect upwards, the first linear module 31 drives the first cylinder 32 and the first pneumatic gripper 33 to move to the first position. This causes the first cylinder 32 to move the first pneumatic gripper 33, the first heat shrink block 34, and the second heat shrink block 35 toward the tube insert 23. The first pneumatic gripper 33 drives the first heat shrink block 34 and the second heat shrink block 35 to close together, thus clamping the heat shrink tubing 70 from the tube insert 23. When cylinder 32 moves upward, it causes heat shrink tubing 70 to detach from tubing fitting 23. Both the first heat shrink block 34 and the second heat shrink block 35 are provided with semi-circular grooves P10, so that when the first heat shrink tubing 70 and the second heat shrink tubing 70 are closed together, the heat shrink tubing 70 is joined and contained within the two semi-circular grooves P10. Thus, the heat shrink tubing 70 can be moved to the second position by the first linear module 31. The second position is above the guide component 50 and the clamping component 40, so that the insertion and heat shrinking operation of heat shrink tubing 70 and optical fiber 60 can be completed at the second position.

[0028] Reference Figure 5 As shown, the wire clamping assembly 40 includes: a mounting plate 41, a second linear module 42, a second cylinder 43, a second pneumatic gripper 44, and two clamping seats 45. The second linear module 42 is mounted on the mounting plate 41 and can use the same type of linear guide rail as the first linear module 31. The second cylinder 43 is mounted on the second linear module 42 and is driven by the second linear module 42 to move vertically. The second pneumatic gripper 44 is mounted on the second cylinder 43 and is driven by the second cylinder 43 to move horizontally. The two clamping seats 45 are mounted on the two gripping fingers of the second pneumatic gripper 44 and are driven by the second pneumatic gripper 44 to separate or close with each other. Furthermore, combined with... Figure 6As shown, the guide assembly 50 includes: a third cylinder 51, a third pneumatic gripper 53, and two guide blocks 54. The third cylinder 51 is fixed on the base frame 10 and located below the pipe feeding assembly 20. The third pneumatic gripper 53 is connected to the third cylinder 51 through a connecting plate 52 and is driven by the third cylinder 51 to move horizontally. The two guide blocks 54 are disposed on the two gripping fingers of the third pneumatic gripper 53 and are driven by the third pneumatic gripper 53 to separate or close with each other.

[0029] In this embodiment, when the first heat shrink block 34 and the second heat shrink block 35 move the heat shrink tubing 70 to the second position, the second cylinder 43 drives the second pneumatic gripper 44 and the two clamping seats 45 holding the optical fiber 60 to move horizontally below the two guide clamping blocks 54. Then, the second linear module 42 drives the second driving gripper and the two clamping seats 45 to move upward, so that the optical fiber 60 moves upward with the two clamping seats 45 to between the two guide blocks. Then, the third pneumatic gripper 53 drives the two guide clamping blocks 54 to close together. Each guide clamping block 54 is provided with a semi-conical groove. 541. When the two guide clamps 54 are driven to close together by the third pneumatic gripper 53, the semi-conical groove 541 is spliced ​​into a conical guide groove, and there is a semi-hole 542 at the top of the semi-conical groove 541. The semi-hole 542 is spliced ​​together with the two guide clamps 54 to form a through hole for engaging the optical fiber 60. When the optical fiber 60 passes through the two guide clamps 54, the conical guide groove can better guide the optical fiber 60, so that the optical fiber 60 can accurately pass through the through hole and extend onto the two guide clamps 54 to complete the insertion operation of the heat shrink tube 70 and the optical fiber 60.

[0030] Optionally, both the first heat shrink block 34 and the second heat shrink block 35 are provided with hot air holes P20. The hot air holes P20 extend from the outside into the semi-circular groove P10, allowing hot air to enter the semi-circular groove P10 through the hot air holes P20. When the first heat shrink block 34 and the second heat shrink block 35 drive the heat shrink tube 70 into the optical fiber 60, hot air is delivered to the semi-circular groove P10 through the hot air holes P20, allowing the heat shrink tube 70 to shrink under heat within the semi-circular groove P10 to be fixed to the optical fiber 60. This ensures a tighter and more reliable fixation between the heat shrink tube 70 and the optical fiber 60. The 4 has a plurality of first protrusions 341 protruding toward the second heat shrink block 35, and a first engaging groove 342 is formed between the plurality of first protrusions 341. The second heat shrink block 35 has a plurality of second protrusions 351 protruding toward the first heat shrink block 34, and a second engaging groove 352 is formed between the plurality of second protrusions 351. When the first heat shrink block 34 and the second heat shrink block 35 are closed together, the first protrusions 341 engage and embed in the second engaging groove 352, and the second protrusions 351 engage and embed in the first engaging groove 342, so that the splicing between the first heat shrink block 34 and the second heat shrink block 35 is more accurate and less prone to displacement.

[0031] The fiber optic heat shrink tubing 70 mechanism provided by this utility model can transport pre-cut heat shrink tubing 70 via a linear feeder 11. When the heat shrink tubing 70 is transported to the end of the linear feeder 11, the tube feeding assembly 20 can pass through the heat shrink tubing 70 and flip it, so that the heat shrink assembly 30 can clamp the heat shrink tubing 70 from the tube feeding assembly 20 and move it above the guide assembly 50. At the same time, the wire clamping assembly 40 can clamp the fiber optic cable 60 and drive it to the bottom of the guide assembly 50, so that the fiber optic cable 60 can pass through the guide assembly 50 and extend onto the guide assembly 50. This allows the heat shrink assembly 30 to drive the heat shrink tubing 70 to be sleeved on the fiber optic cable 60 on the guide assembly 50. The overall structure is simpler, the positioning accuracy of the heat shrink tubing 70 is higher, the transportation is more reliable and simpler, and the efficiency of fiber optic assembly is improved.
