Description

Technical Field

[0001] The present invention relates to optical fiber assembly technology, and in particular to an automatic assembly system for optical fiber components. Background Art

[0002] Optical signal transmission is widely used for signal transmission between electronic devices due to its advantages such as high speed and low interference. Fiber optic components used for optical signal transmission are an important part of the entire signal transmission system.

DETAILED DESCRIPTION

[0050] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0051] like Figures 1 to 22 As shown, the optical fiber component automatic assembly system of the present invention includes a transfer mechanism 1, a conveyor belt 2 and a holding component 3. The transfer mechanism 1 is used to transfer the optical fiber housing. The transfer mechanism 1 clamps the optical fiber housing to be assembled from the conveyor line 16, and after clamping, transfers it to the accommodating area 4 in the middle of the holding component 3. The holding component 3 is transported by the conveyor belt 2 so that it passes through the lower end of the guide block 5. The guide slope 6 at the lower end of the guide block 5 pushes the limiting member 7 to drive the limiting member 8 to rotate, and pushes the holding member 9 to compress the spring 10, so that the elastic sleeve 11 on the limiting member 8 applies pressure on the optical fiber housing in the accommodating area 4, and keeps the position of the optical fiber housing from being offset or loose, so as to facilitate the equipment at the next workstation to install other components that make up the adapter.

[0052] The transfer mechanism 1 is equipped with a transverse moving assembly 12, a vertical moving assembly 13, a rotating assembly 14, a clamping assembly 15, and a conveyor line 16. The vertical moving assembly 13 is mounted on the transverse moving assembly 12 via a mounting plate 17 and moves with the transverse moving assembly 12. The rotating assembly 14 is mounted on the vertical moving assembly 13, and the clamping assembly 15 is mounted at the lower end of the rotating assembly 14. The clamping assembly 15 clamps the optical fiber housing on the conveyor line 16.

[0053] When other components are added, the optical fiber housing can be prevented from positional displacement by retaining component 3, thereby ensuring the installation accuracy of the entire adapter and improving the overall product quality of the adapter.

[0054] The conveyor belt 2 cooperates with the transfer mechanism 1. The conveyor belt 2 is equipped with multiple retaining assemblies 3 for restraining the optical fiber housing. The retaining assemblies 3 are located in the center of the retaining assemblies 3 to accommodate the optical fiber housing. A stopper 8 is located within the accommodation area 4. The rotating stopper 8 can apply external force to the optical fiber housing within the accommodation area 4, thereby restricting the position of the optical fiber housing.

[0055] The guide block 5 is used to cooperate with the holding assembly 3 to confine the optical fiber housing within the accommodating area 4 . A guide inclined surface 6 and a horizontal surface 18 are provided on the bottom surface of the guide block 5 .

[0056] The retaining assembly 3 includes a retaining seat 19, a limiting member 8, a retaining member 9, and a blocking member 20. The limiting member 8, the retaining member 9, and the blocking member 20 are all mounted on the retaining seat 19. The limiting member 8 is used to apply external force to the optical fiber housing. The retaining member 9 is used to limit the rotation angle of the limiting member 8 so that it will not reset under the elastic force of the reset member 21. The blocking member 20 is used to block the spring 10, allowing the elastic force of the spring 10 to act on the movable retaining member 9.

[0057] The holder 19 has two through-holes and an open top, forming a receiving area 4. The holder 19 comprises a base plate 22 and side plates 23 disposed on either side of the base plate 22. The receiving area 4 is formed between the base plate 22 and the side plates 23. The side plates 23 are provided with hinge holes 25 that engage with hinge shafts 24, and sliding slots 26 are provided on the side plates 23.

[0058] The stopper 8 is disposed in the accommodating area 4. One end of the stopper 8 is hinged to the retaining seat 19 via a hinge shaft 24. The other end of the stopper 8 can be rotated to stop the optical fiber housing in the accommodating area 4. The stopper 8 is provided with a guide groove 27 and a fixing groove 28. The guide groove 27 is provided with a guide opening 29.

[0059] An elastic section 30 is formed at the intersection of the fixing groove 28 and the guide groove 27. A limiting member 7 is disposed within the fixing groove 28. The limiting member 7 has an accommodating opening 31 for accommodating the elastic section 30. A symmetrical rod 32 is disposed within the accommodating opening 31. The rod 32 passes through the guide groove 27 and enters the fixing groove 28. The width of the guide groove 27 is smaller than that of the fixing groove 28, and the width of the fixing groove 28 matches the diameter of the rod 32.

[0060] The limiting member 7 is provided with an extension arm 33, on which a rod 32 is mounted. The limiting member 7 limits the maximum rotation angle of the limiting member 8. Furthermore, the limiting member 7 is provided with a contact block 37 that mates with the limiting teeth 34. The limiting member 8 is provided with a first contact surface 35 and a second contact surface 36, which are arranged perpendicularly and mate with the extension arm 33. The first contact surface 35, the second contact surface 36, and the contact block 37 are used to constrain the position of the limiting member 7 on the limiting member 8, maintaining it in a fixed position.

[0061] A ball head 38 is provided on the limiting member 8, and a ball head groove 39 that cooperates with the ball head 38 is provided on the limiting member 7, so that the limiting member 7 needs to be subjected to external force to make the ball head 38 disengage from the ball head groove 39, ensuring that the position of the limiting member 7 will not move.

[0062] The limiting member 8 is provided with a rotation hole 40 that cooperates with the hinge shaft 24, and the reset member 21 is arranged in the rotation hole 40. The limiting member 8 is provided with an extension body 41, which is composed of an extension section 42 and an arc section 43, and the arc section 43 is arranged upward.

[0063] The limiting member 8 is provided with a through opening 75 for avoiding the first limiting section 55 .

[0064] An elastic sleeve 11 is mounted on the extension 41. A mounting groove 44 is located in the center of the elastic sleeve 11 to accommodate the extension 41. The elastic sleeve 11 is also provided with multiple elastic protrusions 45. A cylindrical end 46 is located on the arcuate segment 43. A cylindrical groove 47 is located within the mounting groove 44 to mate with the cylindrical end 46. The diameter of the cylindrical groove 47 is greater than the width of the mounting groove 44.

[0065] The elastic sleeve 11 has a certain elasticity and can play a buffering role, thereby protecting the optical fiber housing and avoiding damage to the optical fiber housing.

[0066] The retaining member 9 is arranged in the accommodating area 4 . A symmetrical sliding groove 26 is provided on the retaining seat 19 , and the retaining member 9 is arranged in the sliding groove 26 .

[0067] The limiting member 8 is provided with a plurality of limiting teeth 34, forming limiting openings 48 between the limiting teeth 34. The retaining member 9 comprises a triangular body 49 and sliding bodies 50 symmetrically arranged on either side of the triangular body 49. The sliding bodies 50 and the triangular body 49 are connected by a connector 51, which is disposed within the sliding groove 26. The triangular body 49 is provided with a limiting end 52 that engages with the limiting openings 48. The upper end of the triangular body 49 is provided with an inclined surface 53, and the lower end is provided with a blocking surface 54.

[0068] When the limit member 8 needs to be reset, an unlocking member 72 is required. A first unlocking slope 73 is provided on the unlocking member 72, and a second unlocking slope 74 is provided on the sliding body 50. The unlocking member 72 is arranged at the upper end of the retaining assembly 3, and a cylinder is used to push the unlocking member 72 downward, so that the first unlocking slope 73 pushes the sliding body 50 to compress the spring 10, so that the limit end 52 disengages from the limit opening 48.

[0069] The limiting end 52 can limit the rotation of the limiting member 8 in the limiting opening 48, and push the inclined surface 53 through the limiting tooth 34, so that the retaining member 9 is pushed to slide in the sliding groove 26 and compress the spring 10.

[0070] A reset member 21 for resetting the limit member 8 is provided between the hinge shaft 24 and the limit member 8. The reset member 21 consists of a first limit segment 55, a second limit segment 56 and a spiral segment 57 for connecting the first limit segment 55 and the second limit segment 56. The limit member 8 is provided with a first through hole 58 for accommodating the first limit segment 55, and the retaining seat 19 is provided with a second through hole 59 for accommodating the second limit segment 56.

[0071] Because the first limiting segment 55 is mounted on the limiting member 8 and can rotate with the limiting member 8, while the second limiting segment 56 is mounted on the retaining seat 19 and does not rotate with the limiting member 8, when the limiting member 8 drives the first limiting segment 55 to rotate, the spiral segment 57 is subjected to force, generating a certain elastic force, thereby storing a certain amount of elastic potential energy. When the limiting end 52 no longer restrains the limiting member 8, the limiting member 8 is reset due to the elastic potential energy stored in the spiral segment 57.

[0072] A symmetrical spring 10 is provided between the blocking member 20 and the retaining member 9 . Under the elastic force of the spring 10 , the retaining member 9 is pushed toward the limiting member 8 , thereby limiting the rotation angle of the limiting member 8 .

[0073] The blocking member 20 consists of a vertical section 60 and transverse sections 61 symmetrically arranged at both ends of the vertical section 60. A notch 62 is formed in the middle of the transverse section 61. A symmetrically arranged locking body 63 is provided on the vertical section 60, and a symmetrical elastic arm 64 is provided on the locking body 63. A locking block 65 is provided on the elastic arm 64, and a first guide slope 66 is provided on the locking block 65.

[0074] An elastic region 67 is formed between the elastic arms 64, and an escape region 68 is formed between the locking body 63 and the transverse section 61. The side plate 23 is disposed within the escape region 68. The sliding groove 26 is provided with a recess 69 that cooperates with the locking body 63. The recess 69 is provided with a wall surface 70 that cooperates with the first guide slope 66. The notch of the sliding groove 26 is provided with a second guide slope 71 that cooperates with the first guide slope 66.

[0075] When the blocking member 20 is installed, the first guiding inclined surface 66 is guided by the second guiding inclined surface 71 so that the locking body 63 enters the sliding groove 26 and then enters the notch 69 for limiting position.

[0076] The optical fiber housing is clamped between two holding components 3 by the clamping assembly 15 , and then driven by the conveyor belt 2 to move the holding components 3 so that the optical fiber housing enters the accommodating area 4 .

[0077] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
