Description

Technical Field

[0001] This utility model relates to the field of fiber optic head cleaning technology, and in particular to an ultrasonic cleaning machine specifically designed for fiber optic heads. Background Technology

[0002] Ultrasonic cleaning technology is widely used in the cleaning of precision optical components, especially for miniature high-precision parts such as fiber optic heads. Its cleaning effect directly affects the stability and reliability of optical signal transmission. In existing technologies, although ultrasonic cleaning equipment can achieve basic cleaning functions, it has significant shortcomings when it comes to cleaning fiber optic heads. Traditional equipment often uses general-purpose clamps, which are difficult to adapt to the tiny size and irregular shape of fiber optic heads. This can lead to loosening, displacement, or mechanical damage during clamping. In addition, the number of items that can be clamped at one time is limited, resulting in low cleaning efficiency. The cleaning process usually relies on manual operation, including multiple manual loading and unloading of workpieces and transferring fiber optic heads between different cleaning tanks. This not only increases the complexity of operation but also easily introduces secondary contamination and reduces the yield rate.

[0003] In addition, existing cleaning machines are often configured with a single or simple multi-tank structure, and the selection and sequence of cleaning solutions lack optimization. For example, a step-by-step cleaning scheme is not designed for the characteristics of grease, dust and solvent residues on the surface of the fiber optic head, resulting in incomplete cleaning or accumulation of residues. In terms of cleaning process control, existing equipment has difficulty in accurately adjusting the immersion depth and rotation positioning of the fiber optic head, and relies heavily on manual adjustment based on the operator's experience, which can easily lead to uneven cleaning, over-immersion or collision damage. Insufficient automation also prevents the equipment from achieving continuous multi-station operation, affecting overall production efficiency.

[0004] Therefore, the inventors urgently needed an ultrasonic cleaning machine specifically designed for fiber optic heads to solve the above problems. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model provides an ultrasonic cleaning machine specifically designed for fiber optic heads, aiming to solve the problems of unstable fiber optic head clamping, low cleaning efficiency, complex operation, and poor cleaning effect in existing ultrasonic cleaning machines.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an ultrasonic cleaning machine specifically for fiber optic heads, comprising a chassis, wherein a U-shaped support frame with an outward opening is provided inside the chassis, and a plurality of ultrasonic cleaning components are sequentially arranged on the U-shaped support frame along the cleaning path. A lifting drive mechanism is mounted in the opening slot of the U-shaped support frame, and a rotary drive mechanism is connected to the output end of the lifting drive mechanism. A turntable is connected to the upper end of the rotary drive mechanism, and a plurality of clamp mounting ports are evenly arranged on the periphery of the turntable. Each clamp mounting port is equipped with a clamp assembly, and the clamp assembly includes two symmetrically arranged pressure plates, a clamp plate located between the two pressure plates, two connecting rods that pass through both ends of the two pressure plates and the clamp plate, and quick-release lever clamps that are hinged to the two ends of the two connecting rods respectively. A plurality of fiber optic head clamping ports are arranged in an array on both sides of the bottom end of the clamp plate, and the opening direction of each fiber optic head clamping port is the lower end face and the side face.

[0007] Based on the above, the beneficial effects of an ultrasonic cleaning machine specifically designed for fiber optic heads are that it solves the problems of unstable fiber optic head clamping, low cleaning efficiency, complex operation, and poor cleaning effect in existing ultrasonic cleaning machines; mainly reflected in:

[0008] 1. This utility model provides a stable support frame through the U-shaped support frame with an outward opening inside the chassis, and several ultrasonic cleaning components are arranged sequentially along the cleaning path, realizing the sequential layout and integrated support of the cleaning station. The output end of the lifting drive mechanism installed in the opening slot of the U-shaped support frame is connected to the rotary drive mechanism. The lifting drive mechanism controls the vertical lifting motion, and the rotary drive mechanism controls the horizontal rotation motion, realizing the precise lifting and rotation positioning of the clamping components, facilitating the continuous execution of the automated cleaning process, reducing manual intervention, avoiding the introduction of secondary pollution, and thus solving the problems of poor cleaning effect and complicated operation.

[0009] 2. This utility model uses a turntable connected to the upper end of a rotary drive mechanism. Several clamp mounting ports are evenly arranged on the periphery of the turntable. Each clamp mounting port is equipped with a clamp assembly. The turntable carries multiple clamp assemblies and realizes workstation switching, realizing batch loading and unloading and synchronous cleaning of multiple fiber optic heads, thereby solving the problem of low cleaning efficiency.

[0010] 3. This utility model uses a quick-release lever clamp of the clamp assembly to fix the pressure plate and the clamp plate with the connecting rod. Several fiber optic head clamping ports are arrayed on both sides of the bottom end of the clamp plate. The opening direction of each fiber optic head clamping port is the lower end face and the side face. This realizes that the fiber optic head is pressed and clamped from the inside of the pressure plate towards the fiber optic head clamping port, which can stably clamp and quickly disassemble and assemble, preventing loosening, displacement or mechanical damage, thereby solving the problem of unstable clamping.

[0011] Furthermore, the inner side of the pressure plate is provided with a groove, and a gasket is provided in the groove. The side of the quick-release lever clamp facing the pressure plate is provided with an arc-shaped protrusion. When the quick-release lever clamp is pressed, the arc-shaped protrusion squeezes the outer side of the pressure plate, so that the gasket and the fiber optic head clamping port of the clamping plate cooperate to clamp the fiber optic head.

[0012] Based on the above, the beneficial effects of the pressure plate are as follows: The groove and gasket on the inner side provide a uniform clamping pressure distribution, protecting the fiber optic head surface from damage and achieving flexible clamping of the fiber optic head; the groove provides installation space and a positioning reference for the gasket, ensuring accurate alignment of the gasket with the fiber optic head clamping opening and achieving precise transmission of clamping force; the gasket acts as a buffer medium, directly contacting the fiber optic head, ensuring sufficient clamping force while preventing damage to the fiber optic head surface, achieving non-destructive clamping of the fiber optic head; the curved protrusion evenly transmits the clamping force of the lever clamp to the pressure plate through its special curved surface design, avoiding local stress concentration and achieving a smooth transition and uniform distribution of clamping force; the quick-release lever clamp amplifies the operating force through the lever principle, enabling one-click quick clamping and releasing, greatly improving loading and unloading efficiency and realizing the quick operation function of the clamp.

[0013] Furthermore, the ultrasonic cleaning assembly comprises four units, each including a cleaning chamber and an ultrasonic generator located within the cleaning chamber. The four cleaning chambers contain ethanol, pure water, pure water, and isopropanol in sequence according to the cleaning path.

[0014] Based on the above, the beneficial effect of the four ultrasonic cleaning components is that by setting up four cleaning chambers in sequence, a multi-level step cleaning process is realized, ensuring that the fiber optic head is thoroughly cleaned and solving the problem of incomplete cleaning by a single method.

[0015] Furthermore, the lifting drive mechanism includes a lifting cylinder, a guide and limit assembly, and a lifting frame. The lifting cylinder is fixed to the inner end face of the housing. The output end of the lifting cylinder passes through the lifting frame and is connected to the bottom of the rotary drive mechanism. The guide and limit assembly includes four vertically arranged limit rods. The lower ends of the four limit rods are connected in pairs. The upper ends of the four limit rods all pass through the lifting frame and are connected to the four corners of the bottom of the rotary drive mechanism. The four limit rods are slidably engaged with the four corners of the upper end face of the lifting frame.

[0016] Based on the above, the beneficial effects of the lifting drive mechanism are that, through the cooperation of cylinder drive and guide limit components, the clamping assembly achieves precise vertical lifting and lowering movement, ensuring that the fiber optic head can be accurately immersed in the cleaning solution; the beneficial effects of the guide limit components are that, through the constraint of four limit rods, swaying or shaking occurs during the lifting process, achieving precise guidance and stable support for the lifting movement.

[0017] Furthermore, buffers are provided on the left and right sides of the upper end face of the lifting frame. When the rotary drive mechanism descends to the trigger position of the buffer, the telescopic rod of the buffer is compressed to mechanically limit it, thereby fixing the immersion depth of the clamp assembly.

[0018] Based on the above, the beneficial effect of the buffer is that it can precisely control the descent position of the clamping assembly through mechanical limiting, thereby achieving optimal immersion depth control of the fiber head in the cleaning solution and solving the problem of inaccurate manual adjustment.

[0019] Furthermore, the rotary drive mechanism includes a drive motor, a rotating shaft assembly, and a motor frame. The drive motor is fixed to the bottom of the front extension plate of the motor frame. The rotating shaft assembly includes a lower bearing, an upper bearing, a rotating shaft rod, and a driven wheel arranged coaxially. The lower end of the rotating shaft rod is connected to the bottom of the motor frame through the lower bearing. The upper bearing is rotatably disposed on the upper inner surface of the motor frame. The upper end of the rotating shaft rod passes through the upper bearing and is connected to the turntable. The driven wheel is fixed to the middle of the rotating shaft rod and meshes with the output end of the drive motor through a belt.

[0020] Based on the above, the beneficial effects of the drive motor are: providing stable and reliable rotational power, enabling precise start and stop of the turntable through control, and meeting the needs of different cleaning processes; the beneficial effect of the lower bearing is: bearing the main axial load of the rotating shaft, ensuring the stable support at the bottom of the rotating mechanism, and preventing radial runout of the rotating shaft; the beneficial effect of the upper bearing is: providing auxiliary support for the upper end of the rotating shaft, forming a double support structure with the lower bearing, enhancing the rigidity and rotational accuracy of the rotating shaft; the beneficial effect of the rotating shaft is: as a core transmission component, transmitting the power of the drive motor to the turntable, realizing the workstation switching function; the beneficial effect of the motor frame is: providing a support platform for the entire rotary drive mechanism, ensuring the accurate installation position of each component.

[0021] Furthermore, the ultrasonic cleaning machine also includes a position detection module, which includes an infrared sensor located on the upper end of the motor frame and five sensing plates arranged around the bottom of the turntable. The position of each sensing plate corresponds one-to-one with each of the fixture mounting ports. When the sensing plate triggers the infrared sensor, the drive motor controls the turntable to stop rotating and position itself.

[0022] Based on the above, the beneficial effects of the position detection module are that it realizes precise positioning control of the turntable through infrared sensing technology, ensuring that each fixture component can be accurately aligned with the corresponding cleaning station, thus solving the problem of inaccurate manual positioning; the beneficial effects of the sensing plate are that it serves as a position marker, corresponding one-to-one with the fixture mounting port, and generates a positioning signal by triggering the infrared sensor, thereby realizing precise angle control of the turntable and ensuring that each station can be accurately positioned.

[0023] The two side walls of the chassis are respectively provided with two upper through holes and two lower through holes. Each of the four cleaning tanks has an inlet connected to an input pipe. The four input pipes are led out through the upper through holes on the same side of the chassis and are respectively connected to four liquid input heads on the outside of the chassis. Each of the four cleaning tanks has an outlet connected to an outlet pipe. The outlet pipes are led out through the lower through holes on the same side of the chassis and are connected to an external recycling device.

[0024] Based on the above, the beneficial effects of the liquid inlet head are: its location on the outside of the chassis facilitates connection to an external liquid supply system, enabling rapid replacement and replenishment of the cleaning fluid and improving operational convenience; the beneficial effect of the inlet pipe is that it connects the external liquid inlet head to the inlet of the cleaning tank, ensuring that fresh cleaning fluid can be accurately delivered to the designated cleaning tank, achieving precise supply of cleaning fluid; the beneficial effect of the outlet pipe is that it connects the outlet of the cleaning tank to external recycling equipment, ensuring that waste liquid can be discharged in a timely manner and centrally treated, achieving environmentally friendly recycling of waste liquid and continuous operation of the equipment.

[0025] Furthermore, the bottom of the inner wall of the fixture mounting port is provided with a step, and the fixture assembly is limited to the fixture mounting port by the step. The five fixture mounting ports of the turntable correspond to the four cleaning boxes and one loading and unloading station, and the loading and unloading station is directly opposite the door of the machine box.

[0026] Based on the above, the beneficial effect of the step is that by setting an annular step at the bottom of the inner wall of the clamp mounting port, a stable support and positioning surface is provided for the clamp assembly, ensuring that the clamp assembly will not sink or shake after installation, thus improving clamping stability.

[0027] Furthermore, the ultrasonic cleaner also includes a controller, which is located on the outer wall of the machine housing. The controller is electrically connected to the lifting drive mechanism, the rotating drive mechanism, the ultrasonic cleaning assembly, and the buffer. When the buffer is triggered, it sends an electrical signal to the controller, and the controller stops the downward movement of the lifting drive mechanism.

[0028] Based on the above, the beneficial effect of the controller is that by centrally controlling the coordinated operation of the lifting drive mechanism, the rotating drive mechanism and the ultrasonic cleaning components, the entire cleaning process is automated, which greatly improves cleaning efficiency and consistency.

[0029] To more clearly illustrate the above-mentioned features of this utility model and the objectives it aims to achieve, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

Detailed Implementation

[0038] like Figures 1-7As shown, an ultrasonic cleaning machine specifically for fiber optic heads includes a housing 1. Inside the housing 1 is a U-shaped support frame 2 with an outward opening. Several ultrasonic cleaning components 3 are sequentially arranged on the U-shaped support frame 2 along the cleaning path. A lifting drive mechanism 4 is mounted within the opening slot of the U-shaped support frame 2. The output end of the lifting drive mechanism 4 is connected to a rotary drive mechanism 5. A turntable 6 is connected to the upper end of the rotary drive mechanism 5. Several clamping mounting holes 61 are evenly arranged on the periphery of the turntable 6. Each clamping hole... Each of the clamp mounting ports 61 is equipped with a clamp assembly 7. The clamp assembly 7 includes two symmetrically arranged pressure plates 71, a clamp plate 72 located between the two pressure plates 71, two connecting rods 73 that pass through both ends of the two pressure plates 71 and the clamp plate 72 respectively, and quick-release lever clamps 74 that are hinged to each end of the two connecting rods 73 respectively. Several fiber optic head clamping ports 721 are arranged in an array on both sides of the bottom end of the clamp plate 72. The opening direction of each fiber optic head clamping port 721 is the lower end face and the side face.

[0039] The inner side of the pressure plate 71 is provided with a groove 711, and a gasket 712 is provided in the groove 711. The quick-release lever clamp 74 has an arc-shaped protrusion 741 on the side facing the pressure plate 71. When the quick-release lever clamp 74 is pressed, the arc-shaped protrusion 741 squeezes the outer side of the pressure plate 71, so that the gasket 712 and the fiber optic head clamping port 721 of the clamping plate 72 cooperate to clamp the fiber optic head.

[0040] The ultrasonic cleaning assembly 3 consists of four components, each including a cleaning tank 31 and an ultrasonic generator 32 located within the cleaning tank 31. The four cleaning tanks 31 contain ethanol, pure water, and isopropanol in sequence according to the cleaning path.

[0041] The lifting drive mechanism 4 includes a lifting cylinder 41, a guide and limit assembly 42, and a lifting frame 43. The lifting cylinder 41 is fixed on the inner end face of the housing 1. The output end of the lifting cylinder 41 passes through the lifting frame 43 and is connected to the bottom of the rotary drive mechanism 5. The guide and limit assembly 42 includes four vertically arranged limit rods 421. The lower ends of the four limit rods 421 are connected in pairs. The upper ends of the four limit rods 421 all pass through the lifting frame 43 and are connected to the four corners of the bottom of the rotary drive mechanism 5. The four limit rods 421 are slidably engaged with the four corners of the upper end face of the lifting frame 43.

[0042] The upper end face of the lifting frame 43 is provided with buffers 431 on the left and right sides. When the rotary drive mechanism 5 descends to the trigger position of the buffer 431, the telescopic rod of the buffer 431 is compressed to mechanically limit it, thereby fixing the immersion depth of the clamp assembly 7.

[0043] The rotary drive mechanism 5 includes a drive motor 51, a rotating shaft assembly 52, and a motor frame 53. The drive motor 51 is fixed to the bottom of the front extension plate of the motor frame 53. The rotating shaft assembly 52 includes a lower bearing 521, an upper bearing 522, a rotating shaft rod 523, and a driven wheel 524 arranged coaxially. The lower end of the rotating shaft rod 523 is connected to the bottom of the motor frame 53 through the lower bearing 521. The upper bearing 522 is rotatably disposed on the upper inner surface of the motor frame 53. The upper end of the rotating shaft rod 523 passes through the upper bearing 522 and is connected to the turntable 6. The driven wheel 524 is fixed to the middle of the rotating shaft rod 523 and meshes with the output end of the drive motor 51 through a belt.

[0044] The ultrasonic cleaner also includes a position detection module 8, which includes an infrared sensor 81 located on the upper end of the motor frame 53 and five sensing plates 82 arranged around the bottom of the turntable 6. The position of each sensing plate 82 corresponds one-to-one with each of the fixture mounting ports 61. When the sensing plate 82 triggers the infrared sensor 81, the drive motor 51 controls the turntable 6 to stop rotating and position itself.

[0045] The two side walls of the casing 1 are respectively provided with two upper through holes 11a at the top and two lower through holes 11b at the bottom. Each of the four liquid inlets of the cleaning tanks 31 is connected to an input pipe. The four input pipes are led out through the upper through holes 11a on the same side of the casing 1 and are respectively connected to four liquid input heads 9 on the outside of the casing 1. Each of the four liquid outlets of the cleaning tanks 31 is connected to an output pipe. The output pipes are led out through the lower through holes 11b on the same side of the casing 1 and are connected to an external recycling device.

[0046] The bottom of the inner wall of the clamp mounting port 61 is provided with a step 611. The clamp assembly 7 is limited to the clamp mounting port 61 by the step 611. The five clamp mounting ports 61 of the turntable 6 correspond to the four cleaning boxes 31 and one loading and unloading station respectively. The loading and unloading station is directly opposite the door of the chassis 1.

[0047] The ultrasonic cleaner also includes a controller 10, which is located on the outer wall of the housing 1. The controller 10 is electrically connected to the lifting drive mechanism 4, the rotation drive mechanism 5, the ultrasonic cleaning assembly 3, and the buffer 431. When the buffer 431 is triggered, it sends an electrical signal to the controller 10, and the controller 10 stops the downward movement of the lifting drive mechanism 4.

[0048] In summary, the specific embodiments of this utility model are as follows:

[0049] The operator opens the door of the chassis 1 and places the fiber optic head to be cleaned into the corresponding clamp assembly 7 at the loading and unloading station. In specific operation, the operator pulls the quick-release lever clamp 74 upward, and its arc-shaped protrusion 741 releases the pressure on the pressure plate 71, so that the pads 712 on the inner side of the two pressure plates 71 separate from the side opening of the fiber optic head clamping port 721 of the clamp plate 72. After inserting the fiber optic head into the clamping port 721, the operator presses the quick-release lever clamp 74, and the arc-shaped protrusion 741 squeezes the outer side of the pressure plate 71, pushing the pads 712 and the clamping port 721 to clamp the fiber optic head together, so as to achieve non-destructive fixation.

[0050] After clamping is completed, the controller 10 instructs the lifting cylinder 41 to push the lifting frame 43 to rise vertically along the four limit rods 421, thereby driving the rotary drive mechanism 5 and the clamp assembly 7 to rise. Then, the controller 10 instructs the rotary drive mechanism 5 to start, and the drive motor 51 drives the driven wheel 524 to rotate through the belt, so that the rotating shaft 523 rotates under the support of the lower bearing 521 and the upper bearing 522, thereby driving the turntable 6 to rotate. When the sensing plate 82 at the bottom of the turntable 6 passes the infrared sensor 81 on the motor frame 53, the positioning signal is triggered, the drive motor 51 stops rotating, and the current clamp assembly 7 is precisely aligned with the first cleaning tank 31 (ethanol tank).

[0051] The lifting cylinder 41 pushes the lifting frame 43 to descend vertically along the four limit rods 421, which drives the rotary drive mechanism 5 and the clamp assembly 7 to move down. When the bottom end of the rotary drive mechanism 5 contacts the buffer 431 on the lifting frame 43, the telescopic rod of the buffer 431 is compressed and sends an electrical signal to the controller 10. The controller 10 immediately stops the lifting cylinder 41 from descending. At this time, the fiber optic head is immersed in the ethanol cleaning solution at a preset depth, and the ultrasonic generator 32 is started to perform primary cleaning.

[0052] After the ethanol cleaning is completed, the lifting cylinder 41 lifts the clamp assembly 7, and the rotary drive mechanism 5 drives the turntable 6 to rotate again, so that the clamp assembly 7 is precisely positioned in the second cleaning tank 31 (pure water tank). The lifting, soaking and ultrasonic cleaning process is repeated. Subsequently, it enters the third cleaning tank 31 (pure water tank) for rinsing and the fourth cleaning tank 31 (isopropanol tank) for dehydration and drying.

[0053] During the cleaning process, the external liquid supply system replenishes the cleaning liquid to each cleaning tank 31 through the liquid inlet head 9 and the inlet pipe. After the cleaning operation is completed, the waste liquid is discharged to the recycling equipment through the outlet pipe from the lower through hole 11b. After all the cleaning is completed, the turntable 6 rotates to the loading and unloading station, and the operator pulls the quick release lever clamp 74 to remove the fiber optic head, thus completing a single cleaning cycle.

[0054] Finally, it should be noted that the four cleaning tanks perform simultaneous and continuous cleaning.

[0055] The above description is only the optimal solution embodiment of this utility model and is not intended to limit this utility model. Various modifications or substitutions made by those skilled in the art to this utility model without departing from the essence and protection scope of this utility model should also be within the protection scope of this utility model.
