Description

Technical Field

[0001] This utility model relates to the field of workbench technology, and in particular to a precision medical device component assembly workbench with negative pressure dust removal. Background Technology

[0002] In the production and assembly of precision medical devices (such as endoscopic optical components, minimally invasive surgical instrument joints, implantable sensors, high-precision infusion pumps, and micro-motor assemblies), environmental cleanliness has a decisive impact on the performance, reliability, and safety of the final product. These devices often involve precise optical coupling surfaces, intricate mechanical transmission interfaces, complex microelectronic connection points, and sensitive surfaces that directly contact biological tissues. Micron- or even submicron-sized dust particles (such as metal shavings, plastic flash, detached microparticles, and electrostatically adsorbed dust) generated during assembly, if adhering to these critical interfaces, will lead to a series of serious consequences:

[0003] Fitting precision failure: In applications such as lens mating surfaces, high-precision thread screwing, miniature bearing pressing, and precision pin connections, tiny particles can hinder the fit of strict tolerance requirements, causing component jamming, poor operation, positioning deviation, and affecting the mechanical performance of the product.

[0004] Existing dust removal methods include installing fixed dust suction ports on the side of the workbench or using local laminar flow hoods. However, fixed dust suction ports have a limited effective range, making it difficult to achieve precise dust removal for assembly points located at different workstations or spatial orientations; while laminar flow hoods are difficult to cover narrow internal connections in some complex assembly scenarios. Therefore, existing devices are insufficient in terms of flexibility and local precision.

[0005] Insufficient suction precision: Due to the inability to precisely control distance and direction, it is difficult to accurately focus negative pressure suction on truly contaminated critical connection interfaces (such as the inside of a tiny threaded hole or the edge where two lenses are about to touch), often resulting in dust-collecting dead zones or areas with insufficient suction. Therefore, a precision medical device component assembly workbench with negative pressure dust collection is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0007] Therefore, one objective of this utility model is to propose a precision medical device component assembly workbench with negative pressure dust removal, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0008] To achieve the above objectives, one embodiment of the present invention provides a precision medical device component assembly workbench with negative pressure dust removal, including a support, a platform, and T-slots. The top of the support is fixedly connected to the platform, and the top surface of the platform is provided with several T-slots.

[0009] The platform is fixedly connected to a joint at its end, and a crossbeam is fixedly connected between the joints;

[0010] The outer surface of the crossbeam is movably connected with several loose sleeves, and the side of each loose sleeve is threaded with a fastening pin, the end of which abuts against the surface of the crossbeam.

[0011] A frame is fixedly connected to the side of the loop, and the frame is a hollow structure;

[0012] The inner side of the frame is fixedly connected to a track, and the outer surface of the track is movably connected to a slider. The surface of the slider is threaded with a fastening pin, and the end of the fastening pin abuts against the surface of the track.

[0013] The front of the slider is fixedly connected to several universal heads, the surface of which is corrugated and the posture of which is adjustable.

[0014] A negative pressure pipe is fixedly connected to the root of the slider, and the negative pressure pipe extends from the root of the frame.

[0015] Preferably, in any of the above schemes, the top of the bracket is welded to the platform, and there are multiple T-slots arranged in a linear array on the platform surface.

[0016] The above technical solution is adopted as follows: This device is an assembly workbench for precision medical device components. The assembly work is carried out on the platform. T-screws can be used at the T-slots to temporarily position and fix the instrument components before assembly.

[0017] To ensure precision at assembly joints and prevent dust from entering, a negative pressure dust removal mechanism is designed during assembly. This mechanism includes a crossbeam, a looper, a locking pin, a frame, a track, a slider, a universal head, and a negative pressure pipe. The negative pressure pipe connects to a negative pressure unit, generating negative pressure air. This air enters through the universal head, providing real-time dust suction and ensuring the cleanliness of the assembly joints. The looper's position on the crossbeam can be adjusted as needed, and then locked in place by the locking pin. During operation, the frame is rotated down, the slider's position on the track is adjusted, and the universal head is brought closer to the assembly joint. The universal head's posture is then adjusted for precise dust suction, ensuring the accuracy of connections at the assembly points of precision medical devices. The dust suction source can be dynamically, precisely, and in real-time deployed to any assembly point, instantly adsorbing and removing dust upon generation, especially at the most sensitive and easily contaminated assembly joints (such as lens mating surfaces, micro-motor drive shaft pressing points, precision threads, and welding points). This significantly reduces the risk of problems such as poor fit, increased friction, electrical short circuits, and reduced biocompatibility caused by dust contamination.

[0018] A clean connection interface is a fundamental prerequisite for achieving high precision in fitting (with stringent tolerance requirements). This device provides a solid quality foundation for the assembly of precision medical devices by actively removing particulate contaminants.

[0019] Preferably, in any of the above embodiments, the looper can move along the axial direction of the crossbeam and lock its position, and the looper can rotate about the axis of the crossbeam and lock its angle.

[0020] The support structure forms the basic support structure of the device. The platform is fixedly installed on the top of the support, providing a stable assembly and operation surface for precision medical device components.

[0021] Multiple T-slots are arranged in a linear array on the top surface of the platform. The design aims to be compatible with T-screws or positioning blocks, providing flexible and reliable temporary positioning and fixation for medical device components to be assembled, ensuring workpiece stability during assembly.

[0022] The core frame of the dust removal mechanism includes joints, which are fixedly connected to the ends of the platform (usually on both sides). A crossbeam is fixedly connected between the two joints, spanning across the assembly platform and forming the main load-bearing beam of the dust removal mechanism. A looper is movably fitted onto the outer surface of the crossbeam. The looper has the following key capabilities: it can freely translate along the crossbeam axis to cover different horizontal working areas; and it can freely rotate around the crossbeam axis to change the working angle.

[0023] The locking pin is threaded onto the side of the looper. Its end can directly abut against the surface of the crossbeam. Tightening the locking pin securely locks the looper in the desired axial position and rotation angle. Typically, the outer end of the locking pin is equipped with a Phillips head for easy operation. Loopers are usually installed in pairs, and the opening direction of their connecting frames can be arranged to face each other or at other reasonable angles as needed.

[0024] The frame is fixedly connected to the looper on the side, and has an overall hollow structure. Its functions are: to serve as a supporting shell for the internal track system; and to provide some space for the negative pressure pipes to run.

[0025] The vacuuming unit includes a track, which is fixedly mounted inside the frame. A slider is movably connected to the outer surface of the track and can slide along it. A locking pin is threaded onto the slider surface (another set of locking pins). Its end can directly abut against the track surface. Tightening this locking pin securely locks the slider in any desired position on the track.

[0026] The universal joint is fixedly connected to the front of the slider (pointing towards the working area). The structure is adjustable in posture, and its direction can be flexibly bent within a certain angle range to achieve precise alignment of assembly points with complex geometries.

[0027] The preferred method is to use a multi-layer composite structure, consisting of, from the inside out: a silicone inner layer (providing a soft seal), a steel wire layer (providing support and shaping), and a plastic outer layer (providing external protection).

[0028] The negative pressure pipe is fixedly connected to the base of the slider and extends from the base of the frame to connect to the external negative pressure system. Its main function is to connect the vacuuming unit to the negative pressure source and ensure unobstructed pipe flow when the slider moves. Part of the negative pressure pipe can be housed inside the hollow interior of the frame to reduce external interference and maintain cleanliness.

[0029] Preferably, in any of the above solutions, the outer end of the fastening pin is fixedly connected with a plum blossom button, and two sets of loose sleeves are provided, with the frame openings on the two sets of loose sleeves facing each other.

[0030] Preferably, in any of the above solutions, the position of the slider on the track is adjustable, and the universal head consists of a silicone inner layer, a steel wire layer, and a plastic outer layer from the inside out.

[0031] Preferably, in any of the above solutions, part of the negative pressure tube is housed within the frame.

[0032] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0033] This precision medical device component assembly workbench with negative pressure dust removal system incorporates a negative pressure dust removal mechanism to ensure precision at assembly joints and prevent dust from entering. This mechanism includes a crossbeam, a looper, a locking pin, a frame, a track, a slider, a universal head, and a negative pressure pipe. The negative pressure pipe connects to a negative pressure generator, generating negative pressure air that enters through the universal head for real-time dust extraction, ensuring cleanliness at the assembly joints. The looper's position on the crossbeam can be adjusted as needed and then locked in place by the locking pin. During operation, the frame is rotated down, and the slider's position on the track is adjusted to bring the universal head closer to the assembly joint. Adjusting the universal head's posture ensures precise dust extraction, guaranteeing the accuracy of the connections at the precision medical device assembly points. The dust extraction source can be dynamically, precisely, and in real-time deployed to any assembly point, instantly adsorbing and removing dust upon generation, especially at the most sensitive and easily contaminated assembly joints (such as lens mating surfaces, micro-motor drive shaft pressing points, precision threads, and welding points). This helps reduce the risk of problems such as poor fit, increased friction, electrical short circuits, and reduced biocompatibility caused by dust pollution.

[0043] like Figure 1-4 As shown, this precision medical device component assembly workbench with negative pressure dust removal includes a support 1, a platform 2, and a T-slot 3. The top of the support 1 is fixedly connected to the platform 2, and the top surface of the platform 2 is provided with several T-slots 3.

[0044] The end of platform 2 is fixedly connected to a joint 4, and a crossbeam 5 is fixedly connected between the joints 4;

[0045] The outer surface of the crossbeam 5 is movably connected with several loose sleeves 6, and the side of the loose sleeves 6 is threaded with a fastening pin 7, the end of the fastening pin 7 abutting against the surface of the crossbeam 5.

[0046] The side of the loop 6 is fixedly connected to a frame 8, which is a hollow structure;

[0047] A track 9 is fixedly connected to the inner side of the frame 8, and a slider 10 is movably connected to the outer surface of the track 9. A fastening pin 7 is threadedly connected to the surface of the slider 10, and the end of the fastening pin 7 abuts against the surface of the track 9.

[0048] Several universal joints 11 are fixedly connected to the front of the slider 10. The surface of the universal joints 11 is corrugated and the posture of the universal joints 11 is adjustable.

[0049] A negative pressure pipe 12 is fixedly connected to the root of the slider 10, and the negative pressure pipe 12 is led out from the root of the frame 8.

[0050] Example 1: The top of the bracket 1 is welded to the platform 2, and multiple T-slots 3 are linearly arrayed on the surface of the platform 2. The loop 6 can move axially along the crossbeam 5 and lock its position, and the loop 6 can rotate about the axis of the crossbeam 5 and lock its angle. The outer end of the fastening pin 7 is fixedly connected with a Phillips head button, and two sets of loops 6 are provided, with the openings of the frames 8 on the two sets of loops 6 facing each other. The position of the slider 10 on the track 9 is adjustable, and the universal head 11 consists of a silicone inner layer, a steel wire layer, and a plastic outer layer from the inside out. Part of the negative pressure tube 12 is housed in the frame 8.

[0051] Example 2: This device is an assembly workbench for precision medical device components. Assembly is performed on platform 2. T-screws can be used at T-slots 3 to temporarily position and fix the device components before assembly. Support 1 forms the basic support structure of the device. Platform 2 is fixedly installed on top of support 1, providing a stable assembly surface for the precision medical device components.

[0052] Multiple linear arrays of T-slots 3 are formed on the top surface of platform 2. The design aims to be compatible with T-screws or positioning blocks, providing flexible and reliable temporary positioning and fixation for medical device components to be assembled, ensuring workpiece stability during assembly.

[0053] The core frame of the dust removal mechanism includes joints 4 and other structures. Joints 4 are fixedly connected to the ends (usually on both sides) of platform 2. A crossbeam 5 is fixedly connected between the two joints 4, spanning across the assembly platform and forming the main load-bearing beam of the dust removal mechanism. A looper 6 is movably fitted onto the outer surface of the crossbeam 5. The looper 6 has the following key capabilities: it can freely translate along the axis of the crossbeam 5 to cover different horizontal working areas; and it can freely rotate around the axis of the crossbeam 5 to change the working angle.

[0054] The tightening pin 7 is threaded onto the side of the looper 6. Its end can directly abut against the surface of the crossbeam 5. Tightening the tightening pin 7 can securely lock the looper 6 in the desired axial position and rotation angle. Typically, the outer end of the tightening pin 7 is equipped with a Phillips head for easy operation. Loopers 6 are usually installed in pairs, and the opening direction of their connecting frame 8 can be arranged to face each other or at other reasonable angles as needed.

[0055] The frame 8 is fixedly connected to the loose sleeve 6 on its side, and has a hollow structure. Its functions are: to serve as a supporting shell for the internal track system; and to provide some space for the negative pressure pipes to run.

[0056] The vacuuming unit mainly includes a track 9, which is fixedly mounted inside the frame 8. A slider 10 is movably connected to the outer surface of the track 9 and can slide on the track 9. A locking pin 7 is threaded onto the surface of the slider 10 (another set of locking pins 7). Its end can directly abut against the surface of the track 9. Tightening this locking pin 7 can securely lock the slider 10 to any desired position on the track 9.

[0057] The universal head 11 is fixedly connected to the front of the slider 10 (pointing towards the working area). The structure is adjustable, allowing it to bend flexibly within a certain angle range, achieving precise alignment of assembly points with complex geometries. A multi-layer composite structure is preferably adopted, consisting of, from the inside out: a silicone inner layer (providing a soft seal), a steel wire layer (providing support and shaping), and a plastic outer layer (providing external protection). The negative pressure pipe 12 is fixedly connected to the root of the slider 10, extending from the root of the frame 8 and connecting to an external negative pressure system. Its main function is to connect the vacuum unit to the negative pressure source and ensure unobstructed flow of the pipes when the slider 10 moves. A portion of the negative pressure pipe 12 can be housed within the hollow interior of the frame 8, reducing external interference and maintaining cleanliness.

[0058] Example 3: The top of the bracket 1 is welded to the platform 2. The crossbeam 5 can be regarded as a stainless steel optical axis. The loop 6 matches the crossbeam 5. The loop 6 can move linearly along the axis of the crossbeam 5. At the same time, the loop 6 can rotate around the axis of the crossbeam 5.

[0059] The working principle of this utility model is as follows:

[0060] Workpiece securing: The operator places the precision medical device component to be assembled on platform 2. Using T-slots 3 in conjunction with dedicated T-nuts or positioning blocks, the workpiece is flexibly and firmly secured, ensuring that it does not shift during delicate operations.

[0061] Dust removal unit preparation: Coarse adjustment and positioning: Based on the key assembly points on the current workpiece that need cleaning (such as snap-fit ​​connections, bearing press-in points, threaded mating surfaces, adhesive surfaces, etc.), the operator loosens the loose pin 7 on the crossbeam 5 beforehand. Then:

[0062] Move the looper 6 along the axis of beam 5 so that its horizontal position roughly covers the target area (e.g., move it to the left or right end).

[0063] Rotate the looper 6 to rotate the entire frame unit 8 to an angle that allows easy access to the assembly point (e.g., rotate it downwards to bring it closer to the platform).

[0064] Precise positioning and locking: After coarse adjustment, immediately tighten the locking pin 7 on the loop 6 to completely lock the spatial position (horizontal and / or angle) of the loop 6 on the crossbeam 5.

[0065] Precise alignment of the suction nozzle: Position adjustment: Loosen the locking pin 7 on the slider 10. Slide the slider 10 along the track 9 inside the frame 8 until the physical position of the universal head 11 is very close to the critical assembly point that requires high cleanliness (such as next to the solder joint or the sealing ring press-fitting area).

[0066] Posture Adjustment: Manually bend the neck of the universal head 11 so that the corrugated surface of its suction port is as close as possible to or slightly in contact with the assembly gap / connection, ensuring that the suction port is directly facing or surrounding the area where dust is most likely to accumulate. The multi-layered composite structure of the universal head 11 ensures that it is not easily damaged during frequent adjustments.

[0067] Locking: After completing the precise positioning and attitude adjustment of the universal head 11, tighten the locking pin 7 on the slider 10 to ensure that the vacuum unit remains stable in subsequent operations.

[0068] Real-time negative pressure dust removal: Negative pressure start: Connect the negative pressure machine (industrial vacuum cleaner or central vacuum system) connected to the external interface of the negative pressure pipe 12 to start the equipment.

[0069] Dynamic suction: Negative pressure is transmitted to the universal head 11 through the negative pressure tube 12, generating a strong suction field at the opening of the universal head 11. At the same time and place as the operator performs assembly actions (such as insertion, tightening, pressing, and gluing), the universal head 11 immediately captures and sucks up the fine dust and debris (such as plastic friction shavings, metal processing residue, and environmental particulate matter) generated during the operation. This "operation point-associated suction" mode is crucial, ensuring that contaminants are quickly removed as soon as they are generated, minimizing the risk of dust settling on precision connecting surfaces, threaded holes, or mating gaps.

[0070] Operational Safety: Throughout the precision assembly process, the universal head 11 continuously operates at the closest distance to the assembly point. The localized negative pressure flow field it generates forms an air barrier, inhibiting external dust from entering the operating area and creating an ultra-clean environment surrounding the critical assembly area.

[0071] Compared with the prior art, the present invention has the following advantages:

[0072] This precision medical device component assembly workbench with negative pressure dust removal system incorporates a negative pressure dust removal mechanism to ensure precision at assembly joints and prevent dust from entering. The mechanism includes a crossbeam 5, a slipknot 6, a locking pin 7, a frame 8, a track 9, a slider 10, a universal head 11, and a negative pressure pipe 12. The negative pressure pipe 12 connects to a negative pressure generator, generating negative pressure air. This air enters through the universal head 11, providing real-time dust suction and ensuring the cleanliness of the assembly joints. The slipknot 6 can be adjusted in position on the crossbeam 5 as needed, and then locked in place by the locking pin 7. During operation, the frame 8 is rotated down, and the slider 10 is adjusted in position on the track 9, bringing the universal head 11 closer to the assembly joint. Adjusting the orientation of the universal head 11 allows for precise dust suction, ensuring the accurate connection of the precision medical device assembly joints. The dust extraction system can be dynamically, precisely, and in real-time deployed to any assembly point, instantly adsorbing and removing dust the moment it is generated, especially at the most sensitive and easily contaminated assembly joints (such as lens mating surfaces, micro-motor drive shaft pressing points, precision threads, and welding points). This significantly reduces the risk of problems such as poor fit, increased friction, electrical short circuits, and reduced biocompatibility caused by dust contamination.
