Description

Technical Field

[0001] The invention relates to a locking mechanism, a full-automatic optical fiber winding machine and a displacement hanging method. Background Art

[0002] The fully automatic fiber optic ring winding machine is an automated equipment specially used for fiber optic winding. It is mainly used for winding fiber optic rings for fiber optic gyroscopes. It is also widely used in the fields of fiber optic communications and fiber optic sensing. The fully automatic fiber optic ring winding machine has a workbench, a left spindle mechanism, a right spindle mechanism, a first fiber supply module, a second fiber supply module, a first displacement module, a second displacement module and a fiber optic ring skeleton. It can be used to achieve multi-level symmetrical automated winding of fiber optic rings. For example, in processes such as the four-level symmetric and hexadecane-pole symmetric winding method, the optical fiber to be wound is first divided into two sections from the midpoint, and the midpoint of the optical fiber is set on the fiber optic ring skeleton. The optical fiber sections at both ends are pre-wound on the fiber supply wheels of the first fiber supply module and the second fiber supply module. The first fiber supply module and the second fiber supply module serve as two fiber supply sources respectively. The first fiber supply module and the second fiber supply module supply fiber to the fiber optic ring skeleton in sequence. When winding optical fibers around a fiber ring frame, the first fiber supply module supplies fiber from the first displacement module and is driven by the first displacement module to shift left and right (i.e., along the X-axis). The second fiber supply module, on the other hand, orbits on the turntables of the left and right spindle mechanisms. Conversely, the second fiber supply module supplies fiber from the second displacement module and is driven by the second displacement module to shift left and right (i.e., along the X-axis). The first fiber supply module and the second fiber supply module alternately supply fiber and orbit around the turntables of the left and right spindle mechanisms. For more details, please refer to published patents such as CN118929345A, CN118954207A, CN219669819U, and CN211234448U.

[0003] Therefore, when the fiber supply module is supplying fiber for winding, it is locked and fixed to the displacement module; however, when the fiber supply module is not supplying fiber and is revolving on the turntable, the fiber supply module and the displacement module are separated from each other. Specifically, the bracket on the fiber supply module and the base on the displacement module are required to be able to lock or separate with each other.

[0004] Regarding the displacement module of the present application, the closest prior art found is a fiber winding machine (CN118929345A). Paragraph

[0048] of its specification indicates that during operation, the first three-axis motion module removes the first fiber supply assembly from the left turntable. The process for removing the first fiber supply assembly is as follows: driven by the first three-axis motion module, the base moves upward along the Z-axis, allowing the matching post on the base to insert into the matching hole. The locking assembly is activated to unlock and release the bracket. The base then continues to move upward along the Z-axis, driven by the first three-axis motion module, removing the first fiber supply assembly. The switching power supply then powers the fourth electrode post, causing the third and fourth electrode posts to attract each other, securing the first fiber supply assembly to the base. The first three-axis motion module then drives the first fiber supply assembly to a suitable winding position. This completes the removal of the first fiber supply assembly from the turntable and secures it to the displacement module. Therefore, the existing fiber supply module bracket and the displacement module base are locked or separated by using the third electrode column and the fourth electrode column to cooperate with each other. However, the above existing structure has the following shortcomings and is analyzed as follows: First, since the bracket on the existing fiber supply module and the base on the displacement module adopt the power on or off control between the third electrode column and the fourth electrode column to achieve mutual adsorption, fixation or separation, it is necessary to control the power on and off under different working states and time nodes, which makes the control algorithm and program logic more complicated and will be affected by electromagnetic interference; secondly, when the fiber supply module is adsorbed and fixed on the three-axis motion module to supply fiber, it needs to be continuously powered on to maintain the suction force, and long-term operation will lead to increased energy consumption and increased operating costs; in addition, when the fiber supply module is hung on or removed from the turntable and displaced by the fiber supply, if the third electrode column and / or the fourth electrode column suddenly loses power (such as circuit or switch failure, etc.), the adsorption magnetic force will disappear, and there will be safety hazards such as mismatch, mutual loosening, inertial movement and collision. Therefore, it cannot maintain the locked state when the power is off, resulting in poor reliability and low safety.

[0005] The spindle module, fiber supply module, displacement module and locking assembly of the fully automatic optical fiber winding machine work together and require high-precision coordination, reliability and stability, as well as precise and smooth connection to ensure that the entire optical fiber winding production runs with ultra-high precision. Therefore, a more reasonable, accurate, stable and reliable locking mechanism is needed. Summary of the Invention

[0006] The present invention provides a displacement module and a fully automatic optical fiber winding machine to solve the problems in the prior art that the bracket on the fiber supply module and the base on the displacement module adopt the power on or off control between the first electrode column and the second electrode column to achieve mutual adsorption or detachment, which makes the control algorithm and program logic more complicated and is subject to electromagnetic interference; the problem that adsorption needs to be maintained all the time during fiber supply, which increases energy consumption; when the fiber supply module is hung on or removed from the turntable or when the fiber is displaced on the displacement module, if the third electrode column and / or the fourth electrode column is suddenly powered off and the adsorption disappears, the locked state cannot be maintained, resulting in poor reliability and low safety.

[0007] In order to achieve the above-mentioned purpose, the technical solution of the present invention is: a locking mechanism is used to be arranged between the bracket on the fiber supply module and the base on the displacement module and can lock or separate the bracket and the base with each other; the characteristics are: the locking mechanism includes an insertion seat and a receiving socket; the insertion seat and the receiving socket are respectively arranged on the base and the bracket or vice versa, and the insertion seat and the receiving socket are respectively arranged on the bracket and the base; the insertion seat is provided with a locking tongue; the locking tongue has a top section, a protruding section, a neck section and a limiting section arranged in sequence; Two clamping assemblies are symmetrically arranged on the receiving socket; the clamping assembly includes a pressure rod and a compression spring, the pressure rod is slidably matched with the receiving socket, the compression spring is used to generate pressure on the pressure rod in a direction perpendicular to the lock tongue, and a ball is provided on the pressing end of the pressure rod; when locked, the two balls of the clamping assemblies symmetrically clamp the neck section of the lock tongue and generate a locking force (F1) between the insertion seat and the receiving socket; and when the displacement module drives the base to displace along the Z axis, the traction force (F2) generated is greater than the locking force (F1).

[0008] Compared with the prior art, the present invention has the following beneficial effects: First, the locking mechanism of the present invention can switch between locking and separation between the bracket and the base when the fiber supply module is removed and hung. The locking force generated during locking is purely mechanical, which is more reliable, stable and has a low failure rate. Secondly, the locking mechanism of the present invention has a top section, a protruding section, a neck section and a limiting section arranged in sequence from top to bottom. When the balls of the two clamping assemblies symmetrically clamp the neck section of the lock tongue and lock it, the limiting section prevents the ball from moving downward, and the protruding section bulges out, causing the ball to generate a large resistance when moving upward. The final locking force is composed of the pre-tightening clamping force between the two balls and the neck section and the resistance between the two balls and the protruding section, which is used to prevent the insertion seat and the receiving socket from relative separation (i.e., separation up and down), realizing mechanical structure coordination, and meeting the requirements of the displacement module for locking and separating switching between the bracket and the base. After locking, the locking mechanism can maintain the locking force without external force, so that the fiber supply module is firmly fixed to the base. At the same time, it can separate automatically when driven by the displacement module to pull along the Z axis. It is simple to control, very stable, and has reliable performance. Third, the locking mechanism of the present invention is configured on a fully automatic optical fiber winding machine, which can automatically hang or remove the fiber supply module on the turntable; at the same time, the fiber supply module can be fixedly constrained on the base and driven by the displacement module to move when winding the fiber, which also overcomes the various defects of the existing technology.

DETAILED DESCRIPTION

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments: Example 1: See Figures 1-8A locking mechanism 3 is provided between the bracket 1-1 on the fiber supply module 1 and the base 2 on the displacement module 4 and enables the bracket 1-1 and the base 2 to be locked with each other (see Figure 3-Figure 4 ) or separation (see Figure 1-Figure 2 ).

[0029] See Figure 5-Figure 8 In this embodiment, the locking mechanism 3 includes an insertion seat 3-1 and a receiving socket 3-2; the insertion seat 3-1 and the receiving socket 3-2 are respectively arranged on the base 1 and the bracket 1-1 or vice versa, and the insertion seat 3-1 and the receiving socket 3-2 are respectively arranged on the bracket 1-1 and the base 1.

[0030] See also Figure 5-Figure 6 Specifically, the insertion seat 3-1 is provided with a lock tongue 3-11; the lock tongue 3-11 has a top section 3-111, a protruding section 3-112, a neck section 3-113 and a limiting section 3-114 arranged in sequence from top to bottom; See also Figure 5-Figure 6 , two clamping assemblies 3-3 are symmetrically arranged on the receiving socket 3-2; the two clamping assemblies 3-3 each include a pressure rod 3-31 and a compression spring 3-32, the pressure rod 3-31 is slidably matched with the receiving socket 3-2, the compression spring 3-32 is used to generate pressure on the pressure rod 3-31 in a direction perpendicular to the lock tongue 3-11, and a ball 3-33 is provided on the pressing end of the pressure rod 3-31; See also Figure 6 When locked, the two balls 3-33 of the clamping assemblies 3-3 symmetrically clamp the neck section 3-113 of the locking tongue 3-11 and generate a locking force F1 between the insertion seat 3-1 and the receiving socket 3-2; and when the XZ-axis driving mechanism 2 drives the base 1 to move along the Z-axis, the traction force F2 generated is greater than the locking force F1.

[0031] See also Figures 1-4 Furthermore, it includes a positioning pin 5 for positioning the base 1 and the bracket 1-1. In this embodiment, the positioning pin 5 is fixed to the base 1, and the bracket 1-1 is provided with a positioning hole 1-11 that cooperates with the positioning pin 5. When the locking mechanism 3 is locked, the positioning pin 5 can improve the relative position accuracy between the base 1 and the bracket 1-1. At the same time, when the locking mechanism 3 is disengaged, the positioning pin 5 and the positioning hole 1-11 can automatically separate from each other.

[0032] In other embodiments, the opposite setting may be adopted, where the positioning pin 5 is fixed to the bracket 1 - 1 , and a positioning hole cooperating with the positioning pin 5 is provided on the base 1 . The working principle is the same, so it will not be described in detail.

[0033] The fiber supply module 1 includes a bracket 1-1, a fiber supply motor, a fiber supply wheel, and a guide wheel assembly, etc. The fiber supply module 1 is used to supply fiber during optical fiber winding, and can adopt existing technology or other structures that meet functional requirements, so it is not described in detail.

[0034] See also Figure 1 Furthermore, the base 2 has a support platform 2-1 and a lower support arm 2-2; the upper surface of the support platform 2-1 is horizontally arranged and is used to horizontally support the bottom surface of the bracket 1-1 to keep the bracket 1-1 stable.

[0035] The output end of the displacement module 4 is connected to the base 2 and is used to drive the base 2 to move.

[0036] See also Figures 1-4 Furthermore, the displacement module is an XYZ module or an XZ module; the displacement module is capable of at least driving the base to move along the X-axis and Z-axis. The XYZ module or XZ module can be purchased and assembled directly. Since its specific structure can be adopted from existing technologies, it will not be described in detail.

[0037] The working principle of the locking mechanism 3 of the present invention is as follows: First, when the fiber supply module is winding, the fiber supply module is on the displacement module and is driven to move along the X axis. At this time: The fiber supply module 1 supplies fiber to the rotating optical fiber ring skeleton 5-4 (this is a known technology and will not be described in detail), and the fiber supply module 1 is located on the base 2 and is locked and fixed by the locking mechanism 3. When the fiber supply module 1 supplies fiber, it is driven by the displacement module 4 to move along the X-axis direction, thereby realizing the sequential winding of the optical fiber on the optical fiber ring skeleton 5-4 along the axial direction (i.e., the X-axis) to complete the current layer of the optical fiber ring.

[0038] At this time, the base 2 horizontally supports the fiber supply module 1, and the base 2 and the bracket 1-1 of the fiber supply module 1 are locked by the locking mechanism 3. At this time, the fiber supply module 1 and the base 2 are locked and fixed without loosening or displacement.

[0039] See also Figure 6Specifically, when locked, the balls 3-33 of the two clamping assemblies 3-3 symmetrically clamp the neck section 3-113 of the lock tongue 3-11 and generate a locking force F1 between the insertion seat 3-1 and the receiving socket 3-2; and the pressure rod 3-31 of the clamping assembly 3-3 is under the action of the compression spring 3-32, and the ball 3-33 at the pressure end of the pressure rod 3-31 will be tightly matched with the neck section 3-113 of the lock tongue 3-11, and the lock tongue 3-11 is symmetrically clamped by the two clamping assemblies 3-3. The neck sections 3-113 of the locking tongue 3-11 are clamped together to achieve symmetrical clamping; and since the neck section 3-113 of the locking tongue 3-11 is recessed inward relative to the protruding section 3-112 and the limiting section 3-114, the combination forms a neck-like middle portion, and the compression spring 3-32 provides sufficient pressure to press the ball 3-33 into the neck section 3-113 and keep it from loosening; when the ball 3-33 of the two clamping components 3-3 is locked with the neck section 3-113 of the locking tongue 3-11, a locking force F1 is generated.

[0040] The locking force F1 is a force generated when the locking mechanism 3 is locked to prevent the insertion seat 3-1 and the receiving socket 3-2 from disengaging from each other. The locking force F1 is used to prevent the insertion seat 3-1 and the receiving socket 3-2 from separating from each other (i.e., separating up and down).

[0041] Compared with the existing known methods (CN118929345A, CN118954207A), the above-mentioned locking mechanism 3 has the following characteristics: First, see Figure 3-Figure 4 Since the base 2 and the bracket 1-1 of the fiber supply module 1 are locked by the above-mentioned locking mechanism 3, and since the locking mechanism 3 is a purely mechanical structure, no power is required during the locking period, and no control algorithm and program logic are required. When locking, the spheres 3-33 of the two clamping components 3-3 symmetrically clamp the neck section 3-113 of the locking tongue 3-11 to generate a locking force, so that the base 2 of the displacement module 4 and the bracket 1-1 of the fiber supply module 1 will not loosen from each other. It is very reliable, ensures work safety, and will not be affected by electromagnetic interference. It does not require additional energy consumption, will be more energy-saving, does not need to add switches, sensors and line controls, etc., and has a lower failure rate.

[0042] Second, when the fiber supply module is not rotating, the fiber supply module is locked on the turntable 5-5 by the locking assembly 5-6, and the base 2 on the displacement module and the bracket 1-1 of the fiber supply module 1 are separated from each other (the locking mechanism 3 is in a separated state), and at this time: See Figure 1-2, the insertion seat 3-1 is on the base 2 on the displacement module 3; the receiving socket 3-2 and its two clamping components 3-3 are on the bracket 1-1 of the fiber supply module 1; and the two balls 3-33 of the two clamping components 3-3 are displaced toward each other and contact each other under the action of their respective compression springs 3-32 (combined with Figure 5 ).

[0043] Third, the locking mechanism 3 used in the existing fully automatic optical fiber winding machine can also be used to remove the fiber supply module from the turntable. The steps are as follows: For details, please refer to steps S11 to S15 in the third embodiment; Fourth, the locking mechanism 3 used in the existing fully automatic optical fiber winding machine can also complete the process of hanging the fiber supply module on the turntable. The steps are as follows: For details, please refer to steps S21 to S25 in the third embodiment. Therefore, the locking mechanism 3 can realize the locking or separation switching between the bracket 1-1 and the base 2 when the fiber supply module 1 is removed or hung up. The locking force generated by the purely mechanical structure during locking is more reliable, stable and has a low failure rate.

[0044] See Figure 5-Figure 8 In this embodiment, the receiving socket 3-2 is provided with the opening 3-21 for the lock tongue 3-11 to avoid when inserted; the receiving socket 3-2 is symmetrically provided with two clamping components 3-3 on both sides of the opening 3-21.

[0045] See Figure 5-Figure 8 In this embodiment, side holes 3-22 for slidingly cooperating with the pressure rod 3-31 are provided on both sides of the opening 3-21; the compression spring 3-32 is installed in the side hole 3-22; the inner end of the compression spring 3-32 is abutted against the inner bottom surface of the side hole 3-22, and the outer end of the compression spring 3-32 is abutted against the pressure rod 3-31.

[0046] See Figure 5-Figure 8 In this embodiment, the compression rod 3-31 includes a thin rod section and a thick rod section; a stepped stop surface 3-312 is formed at the junction of the thin rod section and the thick rod section; the compression spring 3-32 is sleeved on the thin rod section, and the outer end of the compression spring 3-32 abuts against the stepped stop surface 3-312. The compression spring 3-32 is in a compressed state, and can generate sufficient external force on the compression rod 3-31 to press the ball 3-33 into the neck section 3-113 and prevent it from loosening.

[0047] See Figure 5-Figure 8Furthermore, the neck section 3-113 is symmetrically concave toward the center line, and the contour lines on both sides thereof are arc-shaped and have the same radius as the sphere 3-33. The two spheres 3-33 are clamped and locked with the neck section 3-113, and under the action of the compression spring, a locking force is generated that is sufficient to prevent relative loosening, but it is not completely locked. When the traction force of the XZ-axis driving mechanism 2 driving the insertion seat 3-1 is greater than the locking force and the insertion seat 3-1 moves downward relative to the receiving socket 3-2 (at this time, the receiving socket 3-2 and the bracket 1-1 are both fixed on the turntable), the neck section 3-113 of the insertion seat 3-1 first detaches from the neck section 3-113 from the spheres 3-33 of the two clamping assemblies 3-3, and then is sequentially pulled out along the protruding section 3-112 and the top section 3-111 to completely separate, and then moves away.

[0048] See Figure 5-Figure 8 Specifically, the top section 3-111 is arched or pointed. When the locking tongue 3-11 is inserted into the receiving socket 3-2 and locked, the top section 3-111 of the locking tongue 3-11 will smoothly push open the balls 3-33 of the two clamping components 3-3, then continue to push open through the protruding section 3-112, and finally engage with the balls 3-33 of the two clamping components 3-3 through the back neck section 3-113 to lock. The arched or pointed shape of the top section 3-111 can ensure smooth insertion.

[0049] See Figure 5-Figure 8 In the present invention, the lock tongue 3-11 has a top section 3-111, a protruding section 3-112, a neck section 3-113 and a limiting section 3-114 which are arranged in sequence from top to bottom; when the balls 3-33 of the two clamping assemblies 3-3 symmetrically clamp the neck section 3-113 of the lock tongue 3-11 and lock them, the limiting section 3-114 prevents the ball 3-33 from moving downward, and the protruding section 3-112 bulges, causing the ball 3-33 to generate a large resistance when moving upward. The final locking force is jointly composed of the pre-tightening clamping force between the two balls 3-33 and the neck section 3-113 and the resistance between the two balls and the protruding section 3-112, which is used to prevent the insertion seat 3-1 and the receiving socket 3-2 from relative separation movement (i.e., up and down separation), thereby realizing a purely mechanical locking structure.

[0050] Example 2: See Figure 9-18A fully automatic optical fiber winding machine includes a workbench 5-1, two support tables 5-2, two spindle mechanisms 5-3, an optical fiber ring skeleton 5-4, two fiber supply modules 1 and two displacement modules 4; the two support tables 5-2 are fixed on the workbench 5-1 and are spaced apart and relatively distributed on the left and right sides, and the two spindle mechanisms 5-3 are respectively arranged on the two support tables 5-2; each of the two spindle mechanisms 5-3 is provided with a turntable 5-5 and is concentric with each other, and the optical fiber ring skeleton 5-4 is installed on any one of the spindle mechanisms 5-3, and each of the turntables 5-5 is provided with two locking assemblies 5-6 distributed front and back, and the spindle mechanism 5-3, optical fiber ring skeleton 5-4, fiber supply module 1, displacement module 4 and locking assembly 5-6 can adopt existing structures, so they are not described in detail. The key to the present invention is that it has the locking mechanism described in Example 1.

[0051] Example 3: See Figures 9-18 A displacement hanging method adopts the fully automatic optical fiber winding machine described in the second embodiment, which comprises: First, remove the fiber supply module from the turntable. The steps are as follows: S11, first pause the winding, at this time, the fiber supply module is locked and fixed on the turntable by the locking assembly and stops rotating (see Figure 9 ); S12, control the displacement module to work and drive the base to move toward the turntable along the X-axis to the first preset position (see Figure 10 ); S13, control the displacement module to work and drive the base to move upward along the Z axis to the second preset position (see Figure 11 ), and the following requirements are met: The base supports the bracket on the fiber supply module; The base and the bracket are positioned via positioning pins; The insertion seat and the receiving socket of the locking mechanism are symmetrically clamped by the spheres of the two clamping assemblies to the neck section of the lock tongue, thereby generating a locking force (F1), and the bracket and the base are mutually locked; S14, the locking assembly on the control turntable is unlocked and the bracket on the fiber supply module is released (see Figure 12 ); S15, control the displacement module to work and drive the base, bracket and fiber supply module to move away from the turntable to the preset winding position (see Figure 13 ); Second, start the winding work; during winding, control the fiber supply module 1 to work and supply fiber to the rotating optical fiber ring skeleton 5-4, and at the same time the displacement module 4 works and drives the fiber supply module 1 to move unidirectionally or reciprocatingly along the X axis (selected according to the winding requirements, and in this embodiment, reciprocating to achieve double-layer winding) until the winding of the current layer is completed (see Figure 14 ); Third, hang the fiber supply module on the turntable. The steps are as follows: S21, first pause the winding, and the turntable stops rotating; S22, control the displacement module to work and drive the base, bracket and fiber supply module to move together close to the turntable to the third preset position (see Figure 15 ); S23, control the locking assembly on the turntable to lock state and lock the bracket of the fiber supply module to the turntable (see Figure 16 ); S24, control the displacement module to work and drive the base to move downward along the Z axis, and the traction force (F2) generated by the displacement module is greater than the locking force (F1), the base and the bracket will first overcome the locking force (F1) of the locking mechanism and separate from each other; then, the base will continue to move downward along the Z axis driven by the displacement module until it reaches the fourth preset position (see Figure 17 ); S25, control the displacement module to work and drive the base to move away from the turntable to a preset waiting position (see Figure 18 ).

[0052] Then, the other set of fiber supply modules 1 on the opposite side can be started again to perform the winding operation.

[0053] It should be noted that, see Figure 14 , the current fiber supply module 1 is located on the front displacement module 4 when supplying fiber for winding. At this time, the two main shaft mechanisms 5-3 and the optical fiber ring skeleton 5-4 rotate synchronously, and the front fiber supply module 1 supplies fiber to the rotating optical fiber ring skeleton 5-4, and the front displacement module 4 drives the front fiber supply module to move back and forth along the X-axis to the left or first to the left and then to the right, thereby realizing the current layer winding of the first optical fiber segment. In the above winding process, the rear fiber supply module 1 is locked and fixed on the turntable 5-5 (left or right) for orbital motion, and the rear displacement module 1 is located behind the optical fiber ring skeleton 5-4 and remains stationary until the entire layer winding is completed.

[0054] After one layer is wound, the two front and rear displacement modules need to switch their respective working states (see the above-mentioned S11-15 step method or S21-25 step method), and the two fiber supply modules supply fiber alternately and rotate alternately on the turntable, thereby realizing the four-level symmetrical or sixteen-pole symmetrical winding of the optical fiber ring (since the winding method belongs to the existing technology, it will not be repeated).

[0055] Therefore, the locking mechanism 3 of the present invention is configured on the fully automatic optical fiber winding machine, which can automatically hang or remove the fiber supply module 1 on the turntable 5-5; at the same time, when the fiber supply module 1 is winding the fiber, it can also be fixedly constrained on the base 2 and driven by the displacement module 4 to move, and can overcome the various defects of the existing technology.
