Description

Technical Field

[0001] This utility model relates to the field of hydrophone surround splicing, and in particular to a dual-station hydrophone surround fiber mechanism. Background Technology

[0002] Fiber optic hydrophones can be applied in offshore oil and gas exploration, underwater acoustic physics research, and marine fisheries. High-frequency fiber optic hydrophones can be used to measure ultrasonic fields in water for medical measurements. Hydrophones feature low noise, a wide dynamic range, and strong resistance to electromagnetic interference and signal crosstalk. They are suitable for long-distance transmission and arraying; fiber optic transmission has low loss, making it suitable for long-distance transmission; and the integration of signal sensing and transmission improves system reliability. Furthermore, the use of lasers as a light source enhances the reliability of the system. Therefore, the demand for hydrophone production is increasing, making improvements in production efficiency an urgent priority.

[0003] Traditional hydrophone winding machines primarily use single-loop splicing. To improve production efficiency, multiple winding machines are typically used simultaneously. However, due to a shortage of skilled technicians, a single technician often operates and monitors multiple winding machines at the same time. This means that workers frequently have to move between machines, which can lead to situations where one machine is being operated while another is experiencing hydrophone ring gaps or fiber overlap, resulting in insufficient time to address these issues and impacting production efficiency. Utility Model Content

[0004] This invention provides a dual-station hydrophone winding fiber mechanism, which solves the problem of low efficiency in hydrophone winding.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a dual-station hydrophone ring winding mechanism, including a worktable, on which a first station and a second station are arranged side by side. Each of the first station and the second station is provided with a stand, and a fiber feeding mechanism is provided on the stand. The fiber feeding mechanism includes a rotatable fiber feeding disc. A fiber guiding mechanism is provided on one side of the fiber feeding mechanism on the stand. The fiber guiding mechanism includes a lifting plate and a guide wheel assembly. Each of the first station and the second station is provided with a linear movement mechanism. The movement direction of the linear movement mechanism is perpendicular to the lifting direction of the lifting plate. Each linear movement mechanism is provided with a fiber take-up mechanism. The fiber take-up mechanism is provided with a rotatable hydrophone ring frame. A fiber feeding and pressing mechanism is also provided between the fiber take-up mechanism and the guide wheel assembly on the lifting plate. After the optical fiber is emitted from the fiber feeding disc, it passes around the guide wheel assembly and the fiber feeding and pressing mechanism in sequence and is wound around the hydrophone ring frame.

[0006] In a preferred embodiment, the linear motion mechanism is provided with a movable transverse plate. One end of the transverse plate is provided with a fixed seat, and the fixed seat is provided with a rotatable connecting shaft. The connecting shaft is connected to one end of the hydrophone ring frame. The other end of the transverse plate is provided with a movable upright seat, and the upright seat is provided with a rotatable clamping terminal. The clamping terminal presses against the other end of the hydrophone ring frame.

[0007] In the preferred embodiment, the transverse plate is provided with a guide rail, and the guide rail is provided with a sliding block that is slidably connected. The sliding block is connected to the upright, and the sliding block is provided with a threaded locking knob. One end of the locking knob passes through the sliding block and abuts against the guide rail.

[0008] In a preferred embodiment, the fiber feeding mechanism includes a bearing housing connected to the upright frame. The bearing housing contains a rotatable rotating shaft. One end of the rotating shaft on the bearing housing is equipped with a fiber feeding motor, and the fiber feeding disc is sleeved on the other end of the rotating shaft.

[0009] In a preferred embodiment, a swing arm is also provided, which is hinged to the lifting plate and has an encoder at the hinge. A dance wheel is provided at one end of the guide wheel assembly, and an optical fiber passes around the dance wheel from below.

[0010] In a preferred embodiment, the fiber pressing mechanism includes a connecting plate, a rotating seat on the connecting plate, a rotatable extension rod in the rotating seat, and a pressing rod connected to the lower end of the extension rod for pressing fibers.

[0011] In a preferred embodiment, the fiber feeding and pressing mechanism further includes a connecting base, on which a first linear module, a second linear module, and a third linear module are arranged orthogonally in pairs, and the third linear module is connected to the connecting plate.

[0012] The beneficial effects of this utility model are as follows: the dual-station layout on the same equipment greatly reduces costs compared to two independent machines; it avoids workers having to shuttle between multiple machines, reducing labor intensity, and allows workers to promptly detect and adjust the opening of the water ring and the initial stage of fiber stacking, avoiding frequent machine downtime and improving production efficiency; it is equipped with an independent fiber pressing rod adjustment mechanism, which can adjust the contact point in five dimensions in space as the fiber is laid out, meeting the fiber laying accuracy requirements and preventing opening and fiber stacking.

Detailed Implementation

[0024] Example 1: like Figure 1-9 A dual-station hydrophone ring winding mechanism includes a workbench 1 with a first station 101 and a second station 102 arranged side by side. Each of the first station 101 and the second station 102 has a support frame 103. The support frame 103 has a fiber feeding mechanism 2, which includes a rotatable fiber feeding disc 201. A fiber guiding mechanism 3 is provided on one side of the fiber feeding mechanism 2 on the support frame 103. The fiber guiding mechanism 3 includes a lifting plate 301 and a guide wheel assembly 302. Each of the first station 101 and the second station 102 has a linear movement mechanism 4. The movement direction of the linear movement mechanism 4 is perpendicular to the lifting direction of the lifting plate 301. Each linear movement mechanism 4 has a fiber take-up mechanism 6. The fiber take-up mechanism 6 has a rotatable hydrophone ring frame 7. A fiber feeding and pressing mechanism 5 is also provided between the fiber take-up mechanism 6 and the guide wheel assembly 302 on the lifting plate 301. After the optical fiber is emitted from the fiber feeding disc 201, it passes around the guide wheel assembly 302 and the fiber feeding and pressing mechanism 5 in sequence and is wound around the hydrophone ring frame 7.

[0025] The lifting plate 301 has a lifting function, and the final fiber output point of the fiber feeding and pressing mechanism 5 can be freely adjusted in height to adapt to different types of fiber receiving mechanisms 6 and different specifications of hydrophone ring skeletons 7.

[0026] Both workstations can be equipped with the same fiber take-up mechanism 6 and hydrophone ring frame 7, or different types of fiber take-up mechanisms 6 and hydrophone ring frames 7. The same operator can monitor the operation of both workstations simultaneously, avoiding the need to patrol between multiple machines and reducing workload.

[0027] In a preferred embodiment, the linear motion mechanism 4 is provided with a movable transverse plate 401. One end of the transverse plate 401 is provided with a fixed seat 601. The fixed seat 601 is provided with a rotatable connecting shaft 603. The connecting shaft 603 is connected to one end of the hydrophone ring frame 7. The other end of the transverse plate 401 is provided with a movable upright seat 607. The upright seat 607 is provided with a rotatable clamping terminal 608. The clamping terminal 608 presses against the other end of the hydrophone ring frame 7.

[0028] The fixed base 601 is provided with a bearing seat, and a fiber take-up motor 602 is provided on one side. The shaft end of the fiber take-up motor 602 is connected to the connecting shaft 603 to drive the hydrophone ring frame 7 to rotate.

[0029] In a preferred embodiment, the transverse plate 401 is provided with a guide rail 604, the guide rail 604 is provided with a sliding block 605 that is slidably connected, the sliding block 605 is connected to the stand 607, and the sliding block 605 is provided with a threaded locking knob 606, one end of the locking knob 606 passes through the sliding block 605 and abuts against the guide rail 604.

[0030] One end of the connecting shaft 603 can be fitted with a sleeve clamp to clamp one end of the hydrophone ring frame 7. After loosening the locking knob 606, manually push the stand 607 so that the clamping terminal 608 is inserted into the hole at the other end of the hydrophone ring frame 7 and clamps the hydrophone ring frame 7. Rotate the locking knob 606.

[0031] The linear motion mechanism 4 is a screw-guide rail-servo motor structure. The transverse plate 401 is sleeved on the screw through the screw nut and sleeved on the guide rail through the slider. Therefore, the transverse plate 401 can move laterally under the drive of the servo motor, which drives the hydrophone ring skeleton 7 to move laterally to arrange the fibers.

[0032] In a preferred embodiment, the fiber feeding mechanism 2 includes a bearing housing 202, which is connected to the upright frame 103. The bearing housing 202 is provided with a rotatable rotating shaft 203. One end of the rotating shaft 203 on the bearing housing 202 is provided with a fiber feeding motor 204, and the fiber feeding disc 201 is sleeved on the other end of the rotating shaft 203.

[0033] The rotating shaft 203 is provided with a shoulder, and the fiber feeding disc 201 abuts against the shoulder on one side and is locked by a lock nut on the other side.

[0034] In a preferred embodiment, a swing arm 303 is also provided, which is hinged to the lifting plate 301 and an encoder 304 is provided at the hinge. A dance wheel 305 is provided at one end of the guide wheel assembly 302, and an optical fiber passes around the dance wheel 305 from below.

[0035] The upright frame 103 is equipped with a servo lifting module 104, which is a screw-guide rail-servo motor structure, and its lifting mechanism is connected to the lifting plate 301.

[0036] The dance wheel 305 is located between two of the guide wheels in the guide wheel assembly 302, or it can be installed at both ends of the guide wheel assembly 302. When the fiber feeding speed of the first station 101 is lower than the fiber take-up speed of the hydrophone ring frame 7, the fiber tension increases and lifts the dance wheel 305, causing the swing arm 303 to swing upward. After the encoder 304 detects this, it feeds back to the control system and adjusts the rotation speed of the first station 101 or the hydrophone ring frame 7 to restore the tension to normal, and vice versa.

[0037] In a preferred embodiment, the fiber pressing mechanism 5 includes a connecting plate 505, a rotating seat 506 on the connecting plate 505, a rotatable extension rod 507 in the rotating seat 506, and a pressing rod 508 connected to the lower end of the extension rod 507. The pressing rod 508 is used for pressing fibers.

[0038] In a preferred embodiment, the fiber feeding and pressing mechanism 5 further includes a connecting base 501, on which a first linear module 502, a second linear module 503 and a third linear module 504 are arranged orthogonally in pairs, and the third linear module 504 is connected to the connecting plate 505.

[0039] The first linear module 502, the second linear module 503, and the third linear module 504 all have a screw-guide rail-servo motor structure, forming a Cartesian moving mechanism, which allows the connecting plate 505 to move in three dimensions. At the same time, the swing motor 509 can drive the rotating seat 506 to swing, and the angle motor 510 can drive the extension rod 507 to rotate. Therefore, the fiber pressing angle of the fiber pressing rod 508 can be freely adjusted. In addition to being able to adapt to different specifications of hydrophone ring skeleton 7, it can also make the fiber arrangement accuracy higher.

[0040] Example 2: A dual-station hydrophone surround fiber machine includes a worktable assembly, a fiber take-up assembly, a clamping assembly, a fiber feeding assembly, a fiber optic cable arrangement assembly, a guide assembly, an optical fiber-assisted cable arrangement mechanism assembly, and a camera assembly.

[0041] The workbench assembly is mainly used to fix and support the welding frame, touch screen, display and other components; The fiber take-up assembly is mainly used by the servo motor to drive the frame to take up fibers at a stable speed according to the set fiber take-up speed; The clamping assembly is a tooling that fixes the skeleton inside the bearing, thus clamping the skeleton. The fiber feeding assembly is driven by a servo motor that provides real-time rotation speed based on real-time feedback parameters, thereby maintaining stable tension on the optical fiber along the path. The fiber arrangement assembly is equipped with a linear motor module with a grating ruler, which has high positioning accuracy. Its function is to act as a displacement slide for winding optical fibers on the skeleton. Each time an optical fiber is wound, the slide moves one optical fiber diameter distance, and the winding length is achieved by winding back and forth.

[0042] The guide assembly is an integrated component that monitors winding tension, length, and other parameters online. The function of the lifting slide is to raise the slide by the diameter of one optical fiber for each layer of optical fiber wound.

[0043] The fiber optic auxiliary fiber arrangement mechanism is used to wind the optical fiber onto the hydrophone frame, which acts as a fiber stopper and compressor, ensuring that the optical fiber is wound onto the frame without gaps or overlaps.

[0044] The camera assembly is used for image monitoring. Equipped with a CCD camera, it can clearly display the fiber optic winding status on the screen. The CCD camera is equipped with a three-dimensional adjustment slide, which can easily and quickly adjust the clarity on the screen. It can save real-time images (videos) of the fiber winding as needed. When a fault or alarm occurs, it automatically records the current image. The image should be in focus and easy to identify.

[0045] The efficiency has been greatly improved, allowing one person to operate two workstations instead of one person operating a single machine, achieving dense arrangement in the middle without manual intervention.

[0046] The working principle is as follows: First, the fiber distribution tray is manually placed on the fiber placement assembly. Then, the optical fiber is wound onto the guide assembly according to the fiber winding path, and then wound onto the hydrophone ring frame for fixation. The winding parameters, such as the number of turns per layer, fiber diameter, winding speed, and total winding length, are set on the left touchscreen. The fiber take-up button is then activated to begin winding. The PTFE (polytetrafluoroethylene) tool pen in the auxiliary fiber placement assembly presses down onto the frame to block and press down the last turn of fiber. Each rotation of the take-up assembly moves the fiber placement assembly a distance equal to one fiber diameter. Winding proceeds from left to right, then from right to left, repeating this process to achieve the required length. The same parameters are set on the touchscreen at the right station, and both stations can perform winding simultaneously.

[0047] The core of this invention is a machine that installs two identical winding water ring mechanisms, allowing one person to operate two machines, thus improving production efficiency.

[0048] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
