Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a negative pressure medical glove smart wearable device and method. Background Technology

[0002] Medical gloves (latex gloves, nitrile gloves) are a crucial barrier against cross-infection during medical procedures. Prevention is key; if a patient's blood, bodily fluids, secretions, and excretions (excluding sweat) are potentially infectious, protective measures must be taken when we come into contact with these substances, and gloves are one of the most direct barriers. Medical gloves are worn in many clinical settings. Besides the situations mentioned above, they are also necessary when handling anti-tumor drugs, primarily to protect against the toxicity of chemotherapy drugs, avoid direct skin contact, and protect the safety of medical staff and patients.

[0003] Of course, gloves may be worn in daily life to improve cleanliness, including when handling food, cleaning, garbage disposal, beauty treatments, and treating wounds. Therefore, smart wearable gloves can help us save time when putting on gloves, avoid waste due to improper use, and improve work efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a negative pressure medical glove smart wearable device and method, mainly to solve the problem of excessive glove waste caused by long glove wearing time and improper handling.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A negative pressure medical glove smart wearable device includes a housing, an inlet on one side of the housing, multiple suction tubes connected to an air pump on the inner wall of the housing away from the inlet, a transparent cover for observation on the top of the housing, a visual sensor mounted on the housing above the inlet, an opening module for opening and transferring the glove on one side of the housing near the inlet, a sealing module for closing the opened glove between the two sides of the housing, a sealing module for creating a sealed environment in the middle of the housing, and a feeding module for storing and feeding the glove below the sealing module.

[0007] Furthermore, the expansion module includes two support groups disposed on the side of the housing near the inlet, with a mounting frame between the two support groups. Two rotating frames are rotatably connected to one side of the mounting frame, and an insertion rod is welded to one end of each rotating frame. The two insertion rods are combined to form a cylinder with a conical structure. A drive assembly is provided on one side of the mounting frame to drive the two rotating frames to move in opposite directions.

[0008] Based on the aforementioned scheme, both support groups include two connecting rods that rotate on one side of the housing. The two connecting rods are of the same length and are arranged in parallel with the housing mounting side as the plane. A first servo motor is fixed to the inner wall of one side of the housing by bolts, and the output shaft of the first servo motor is fixed to one of the connecting rods.

[0009] As a further embodiment of the present invention, the drive assembly includes a second servo motor fixed to one side of the mounting bracket, and the output shaft of the second servo motor is fixed to one of the rotating brackets. Gears are fixed to the same side of both rotating brackets by bolts, and the two gears mesh with each other.

[0010] Furthermore, the sealing module includes linear motors mounted on the inner walls of both sides of the housing, and a circular clamp is fixed between the two linear motors by bolts.

[0011] Based on the aforementioned scheme, the enclosed module includes a fixing plate fixed to the inner walls of multiple sides of the housing, and at least one first electric push rod is fixed to the bottom inner wall of the housing by bolts. The movable end of the first electric push rod is fixed to a sealing plate by bolts.

[0012] As a further embodiment of the present invention, the feeding module includes at least one second electric push rod fixed to the inner wall of the bottom of the housing. The top of the second electric push rod is fixed with a mounting plate by bolts. The top of the mounting plate is provided with a movable frame, and the glove is placed on the movable frame.

[0013] Furthermore, a third electric push rod is fixed to one side of the mounting plate by bolts. The movable end of the third electric push rod is fixed to the movable frame. A sliding groove is provided on one side of the fixed plate. A movable plate is slidably connected in the sliding groove. Grooves are provided on the opposite sides of the movable plate and the sliding groove. A first magnetic block and a second magnetic block are respectively bonded in the grooves, and the magnetic poles of the opposite sides of the first magnetic block and the second magnetic block are opposite.

[0014] Based on the aforementioned scheme, baffles are slidably connected to both sides of the movable frame, and a connecting frame is welded to the same side of the two baffles. A tension spring is fixedly installed between the connecting frame and the movable frame.

[0015] A method for intelligently wearing negative pressure medical gloves includes the following steps:

[0016] Step 1: First, stack the gloves on top of each other, then place them neatly on the feeding module;

[0017] Step 2: Input the command to make the closing module, sealing module and opening module run. First, the closing module releases the sealed environment of the shell. Then, the feeding module feeds the glove. After that, the opening module opens the glove so that the glove's insertion direction faces the inlet. The sealing module closes the opened glove. The feeding module and closing module are then reset.

[0018] Step 3: Start the air pump. The air pump will extract the air from the shell, creating a negative pressure inside the shell, which will fully expand the glove. At this point, you can insert your hand into the fully expanded glove.

[0019] Step 4: After the hand is fully inserted into the glove, the sealing module resets, thus bringing the device to its initial state.

[0020] Compared with the prior art, the present invention provides a negative pressure medical glove smart wearable device and method, which has the following beneficial effects:

[0021] 1. Through the coordinated use of multiple modules, this invention enables fully automated operation of the entire process from glove storage, automatic feeding, precise opening, negative pressure assisted wearing to device reset. The entire process does not require manual contact with the outside of the glove, effectively avoiding the risk of cross-contamination that may occur during the wearing process. It also prevents other gloves from falling out when taking gloves out of the glove box, reducing glove waste and improving work efficiency.

[0022] 2. The present invention has an opening module that opens and transports the glove, which can accurately transport the opened glove to a preset position corresponding to the insertion port, so that the glove insertion direction is highly consistent with the insertion path of the operator's hand, effectively improving the alignment efficiency during wearing and avoiding problems such as difficulty in wearing or glove displacement due to positional deviation.

[0023] 3. By incorporating a sealing module, this invention can eliminate the problem of the glove opening edge not fitting against the inner wall of the shell 1, ensuring a good sealing environment between the glove opening and the shell during the wearing process. This avoids problems such as negative pressure failure or wrinkles and bubbles during the wearing process due to poor sealing, thus ensuring the efficiency and reliability of the entire wearing process.

[0024] 4. The present invention improves the overall airtightness of the device by providing a closed module, with the sealing plate 10 and the fixing plate 12 closely fitting together to form a seal on the bottom of the housing 1.

[0025] 5. By incorporating a feeding module, this invention enables automated glove feeding, significantly reducing manual intervention and further enhancing the automation level and continuous operation capability of the entire device. Attached Figure Description

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0033] The component designations used in this document, such as "first" and "second," are merely for distinguishing the described objects and do not have any sequential or technical meaning. The terms "connection" and "linkage" used in this invention, unless otherwise specified, include both direct and indirect connections (linkages). It should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0035] Example 1, please refer to Figures 1-5 As shown, a negative pressure medical glove smart wearable device includes a housing 1. An inlet 4 is provided on one side of the housing 1. Multiple suction pipes 6 connected to a suction pump are provided on the inner wall of the housing 1 away from the inlet 4. A transparent cover 2 for observation is provided on the top of the housing 1. A vision sensor 3 is installed on the housing 1 above the inlet 4. The vision sensor 3 is model FV-LM2070. An opening module for opening and transferring the glove is provided on one side of the housing 1 near the inlet 4. A sealing module for closing the opened glove is provided between the two sides of the housing 1. A sealing module for creating a sealed environment is provided in the middle of the housing 1. A feeding module for storing and feeding the glove is provided below the sealing module.

[0036] Based on the above, the intelligent wearing method for negative pressure medical gloves is as follows:

[0037] Step 1: First, stack the gloves on top of each other, then place them neatly on the feeding module;

[0038] Step 2: Input the command to make the closing module, sealing module and opening module run. First, the closing module releases the sealing environment of the shell 1. Then, the feeding module feeds the glove. After that, the opening module opens the glove so that the glove's insertion direction faces the insertion port 4. The sealing module closes the opened glove. The feeding module and closing module are then reset.

[0039] Step 3: Start the air pump. The air pump will extract the air from the housing 1, thereby creating a negative pressure inside the housing 1, which will fully expand the glove. At this time, you can put your hand into the fully expanded glove.

[0040] Step 4: After the hand is fully inserted into the glove, the sealing module resets, thus bringing the device to its initial state.

[0041] The start and stop of the air pump can be monitored and controlled in real time by the vision sensor 3. When the vision sensor 3 detects that a hand is inserted into the inlet 4, it will automatically send a start signal to the air pump to make the air pump start working to create a negative pressure environment inside the housing 1. When it detects that the operator's hand is wearing gloves when pulling back, the vision sensor 3 will immediately trigger the air pump to stop pumping air, ensuring that the gloves remain stably open during the wearing process, and avoiding the gloves from prematurely fitting the hand due to the disappearance of negative pressure, which would affect the smoothness of wearing.

[0042] By using multiple modules in combination, this negative pressure medical glove smart wearable device and method realizes fully automated operation from glove storage, automatic feeding, precise opening, negative pressure assisted wearing to device reset.

[0043] The entire process does not require manual contact with the outside of the gloves, effectively avoiding the risk of cross-contamination that may occur during the wearing process. It also prevents other gloves from falling out when gloves are taken out of the glove box, reducing glove waste and improving work efficiency.

[0044] Meanwhile, the real-time monitoring and feedback mechanism of the vision sensor 3 further improves the stability of the device operation and the success rate of wearing gloves, significantly reducing the time cost and operational difficulty of manually putting on gloves, and providing medical workers with a safer and more efficient wearing solution.

[0045] In order to achieve automatic opening and transfer of gloves;

[0046] The expansion module includes two support groups disposed on the side of the housing 1 near the inlet 4. A mounting frame 18 is provided between the two support groups. Two rotating frames 15 are rotatably connected to one side of the mounting frame 18. An insertion rod 16 is welded to one end of the rotating frame 15. The two insertion rods 16 are combined to form a cylinder with a conical structure. A drive assembly is provided on one side of the mounting frame 18 to drive the two rotating frames 15 to move in opposite directions.

[0047] The support group drives the mounting frame 18 to change position, and the drive component drives the two rotating frames 15 to rotate, so that the two insertion rods 16 come into contact and form a cylinder with a conical head. When the insertion rod 16 is inserted into the glove, the drive component drives the rotating frame 15 to rotate in the opposite direction, thereby opening the glove. The opened glove moves to the designated position with the mounting frame 18 under the action of the support group, so as to facilitate subsequent wearing operations.

[0048] During this process, the precise control of the drive components ensures that the rotation angle and opening force of the insertion rod 16 are just right, which can effectively open the glove while avoiding damage to the glove due to over-opening.

[0049] Meanwhile, the tapered design allows the insertion rod 16 to be smoothly inserted into the glove opening, reducing friction and pulling on the glove and further ensuring the integrity of the glove during the opening process.

[0050] In order to achieve parallel rotation of mounting bracket 18;

[0051] Both support groups include two connecting rods 9 that rotate on one side of the housing 1. The two connecting rods 9 are of the same length and are arranged in parallel with the mounting side of the housing 1 as the plane. A first servo motor 8 is fixed to the inner wall of one side of the housing 1 by bolts, and the output shaft of the first servo motor 8 is fixed to one of the connecting rods 9.

[0052] The first servo motor 8 is activated, which drives the connecting rod 9 to rotate. Since the two connecting rods 9 are arranged in parallel with the mounting side of the housing 1 as the plane and are of the same length, when one of the connecting rods 9 rotates under the drive of the first servo motor 8, it will drive the other connecting rod 9 to rotate synchronously in the opposite direction through the cross-parallel structural characteristics. This ensures that the ends of the two connecting rods 9 are always kept on the same horizontal plane, so as to realize the smooth movement of the mounting bracket 18, avoid tilting or offset during the position adjustment process, and ensure that the insertion rod 16 can be accurately aligned with the glove and complete the subsequent opening and transfer operations.

[0053] This design of intersecting parallel connecting rods 9 not only simplifies the transmission structure of the support group, but also ensures the consistency and stability of movement through mechanical linkage, reduces the dependence on complex control systems, and improves the overall reliability of the device operation.

[0054] In order to achieve synchronous rotation of the two rotating frames 15;

[0055] The drive assembly includes a second servo motor 14 fixed to one side of the mounting bracket 18, and the output shaft of the second servo motor 14 is fixed to one of the rotating brackets 15. Gears 17 are fixed to the same side of both rotating brackets 15 by bolts, and the two gears 17 mesh with each other.

[0056] When the second servo motor 14 is started, its output shaft drives the rotating frame 15 connected to it to rotate. The gear 17 on the same side of the rotating frame 15 rotates synchronously. Since the two gears 17 mesh with each other, the actively rotating gear 17 will drive the other gear 17 to rotate in the opposite direction, thereby making the other rotating frame 15 rotate synchronously and in the opposite direction with the former, ensuring that the two rotating frames 15 can move at the same speed and in opposite directions, so as to realize the stable clamping or spreading action of the insertion rod 16 on the object.

[0057] This gear meshing transmission method features high transmission accuracy and fast response speed, and can precisely control the rotation angle of the two rotating frames 15, avoiding operational deviations caused by asynchronous rotation.

[0058] Meanwhile, the compact structure of the gear transmission also makes the layout of the drive components on the mounting frame 18 more reasonable, reducing space occupation and providing favorable conditions for the miniaturization design of the device.

[0059] To eliminate the gap between the stretched glove and the shell 1;

[0060] The sealing module includes linear motors 5 mounted on the inner walls of both sides of the housing 1, and a circular clamp 7 is fixed between the two linear motors 5 by bolts;

[0061] After the glove is opened, the linear motor 5 is started. The linear motor 5 will drive the ring clamp 7 to move horizontally, so that the ring clamp 7 and the protrusion on the inner wall of the housing 1 together clamp the glove. This clamping method can eliminate the problem that the opening edge of the glove does not fit against the inner wall of the housing 1.

[0062] The inner side of the circular clamp 7 is also attached with a flexible rubber pad, which can increase the friction between the glove and the glove during the clamping process, prevent the glove from slipping during use, and avoid rigid contact that could damage the rubber glove.

[0063] In addition, the stroke of the linear motor 5 can be precisely controlled by a control system (such as a PLC controller), which can accurately ensure the position of the ring clamp 7 and ensure the sealing effect.

[0064] The sealing module creates a relatively enclosed space between the glove and the housing 1, effectively preventing external dust and impurities from entering the device and providing good protection for the subsequent operating environment.

[0065] In order to achieve a closed environment inside the casing 1;

[0066] The enclosed module includes a fixing plate 12 fixed on the inner walls of multiple sides of the housing 1. At least one first electric push rod 11 is fixed to the bottom inner wall of the housing 1 by bolts. The movable end of the first electric push rod 11 is fixed to a sealing plate 10 by bolts.

[0067] The contact dimensions between the sealing plate 10 and the fixing plate 12 are adapted to the inner walls of the housing 1. When the first electric push rod 11 extends, it can push the sealing plate 10 upward until it fits tightly against the fixing plate 12, forming a seal on the bottom of the housing 1 and improving the overall airtightness of the device.

[0068] The inner side of the sealing plate 10 is provided with a groove, and an elastic sealing strip is embedded in the groove. When the sealing plate 10 comes into contact with the fixing plate 12, the sealing strip will be squeezed and deformed, further enhancing the sealing between the two.

[0069] In addition, the extension and retraction speed of the first electric push rod 11 can be adjusted according to actual needs. While ensuring sealing efficiency, it avoids impacting the internal components of the device due to excessively fast movement. The sealing module and the sealing module work together to build a double sealing barrier inside the housing 1, which significantly improves the overall sealing performance of the device.

[0070] In order to load the gloves;

[0071] The feeding module includes at least one second electric push rod 13 fixed to the inner wall of the bottom of the housing 1. The top of the second electric push rod 13 is fixed with a mounting plate 19 by bolts. The top of the mounting plate 19 is provided with a movable frame 21, and the glove is placed on the movable frame 21.

[0072] Activate the second electric push rod 13. The extension of the second electric push rod 13 will cause the mounting plate 19 and the moving frame 21 to move upward, so that the glove is located at the flipped insertion rod 16, so that the insertion rod 16 can be accurately inserted into the opening end of the glove.

[0073] In addition, the stroke of the second electric push rod 13 can be preset by the control system. When the moving frame 21 moves the glove to the designated position, the second electric push rod 13 will automatically stop extending to avoid the glove from colliding and being damaged by the insertion rod 16 due to excessive movement.

[0074] To allow the insertion rod 16 to be inserted inside the glove;

[0075] A third electric push rod 20 is fixed to one side of the mounting plate 19 by bolts. The movable end of the third electric push rod 20 is fixed to the movable frame 21. A sliding groove 25 is provided on one side of the fixing plate 12. A movable plate 26 is slidably connected in the sliding groove 25.

[0076] When the second electric push rod 13 extends, it will cause the glove to come into contact with the moving plate 26, thereby clamping the glove on the moving frame 21. When the third electric push rod 20 extends and retracts, it will drive the moving frame 21 to move horizontally. During the movement, the moving frame 21 will push and drive the moving plate 26 to slide horizontally along the slide groove 25, thereby allowing the insertion rod 16 to be inserted into the opening end of the glove. At this time, the glove can be opened.

[0077] The sliding direction of the movable plate 26 is consistent with the extension and retraction direction of the third electric push rod 20, ensuring that the glove can stably move with the movable frame 21 while in the clamping state;

[0078] In addition, rollers are provided between the slide 25 and the moving plate 26, which can reduce the frictional resistance when the moving plate 26 slides, reduce wear between components, and extend the service life of the device.

[0079] The control system will automatically adjust the extension and retraction of the third electric push rod 20 according to the size and model of the glove and the position of the first electric push rod 11. This will keep the clamping force between the moving frame 21 and the moving plate 26 within a reasonable range, firmly clamp the glove, and prevent the glove from being deformed or damaged due to excessive pressure. It will also avoid the movement of the sealing plate 10, preventing the glove from being damaged by the sealing plate 10.

[0080] After the insertion rod 16 completes the operation of opening the glove, the second electric push rod 13 will drive the moving frame 21 to move in the opposite direction and reset. The moving plate 26 will also slide back to the initial position along the slide groove 25, preparing for the next glove loading and insertion operation.

[0081] The movable plate 26 and the slide 25 are provided with grooves on opposite sides, and a first magnetic block 27 and a second magnetic block 28 are respectively bonded in the grooves, and the magnetic poles of the first magnetic block 27 and the second magnetic block 28 are opposite on opposite sides.

[0082] When the movable plate 26 slides along the slide groove 25 to the initial position, the first magnetic block 27 and the second magnetic block 28 will fit tightly together due to the magnetic force of opposite poles attracting each other, thereby assisting in positioning the movable plate 26 and preventing it from sliding accidentally due to equipment vibration and other factors when it is not in operation, ensuring that the movable plate 26 can be accurately positioned for clamping in the next operation.

[0083] This magnetic adsorption positioning method eliminates the need for additional mechanical locking structures, which simplifies the overall design of the device and reduces the rigid collision between the moving plate 26 and the end of the slide 25 when it is reset through the buffering effect of magnetic force, thereby reducing noise and impact damage during component operation.

[0084] After the insertion rod 16 completes the operation of opening the glove, the second electric push rod 13 will drive the moving frame 21 to move in the opposite direction and reset. The moving plate 26 will also slide back to the initial position along the slide groove 25, preparing for the next glove loading and insertion operation.

[0085] In order to limit the position of the gloves placed on the movable rack 21;

[0086] Both sides of the movable frame 21 are slidably connected to baffles 22, and a connecting frame 23 is welded to the same side of the two baffles 22. A tension spring 24 is fixedly installed between the connecting frame 23 and the movable frame 21.

[0087] In its natural state, the tension spring 24 will exert an inward pulling force on the connecting frame 23, causing the two baffles 22 to move upward, thereby limiting the two sides of the glove and preventing the glove from shifting or slipping due to inertia during the movement of the moving frame 21.

[0088] When the moving frame 21 moves upward, the baffle 22 also moves upward, so that the baffle 22 can contact the moving plate 26 and be squeezed downward, thereby stretching the tension spring 24, so that the glove located between the two baffles 22 can contact the moving plate 26. At this time, the downward movement of the baffle 22 will not affect the clamping action of the moving plate 26 on the glove, and after the glove has completed the opening operation, it can move upward under the elastic restoring force of the tension spring 24 as the moving frame 21 returns to its original position, and re-limit the glove, ensuring that the glove is always in a stable waiting state throughout the entire operation process.

[0089] This limiting structure, which uses a tension spring 24 in conjunction with a baffle 22, is not only flexible in operation and can adapt to the limiting requirements of gloves of different sizes, but also plays a continuous role during the movement and operation of the mobile frame 21, effectively improving the stability and reliability of glove handling.

[0090] The present invention is used in the following steps:

[0091] S1: Stack the gloves on both sides, then place them neatly on the moving rack 21, with the gloves positioned between the two baffles 22;

[0092] S2: Input command to make the device run;

[0093] S3: Activate the first electric push rod 11. The retraction of the first electric push rod 11 will cause the sealing plate 10 to move downward to make way for the mounting bracket 18.

[0094] S4: Start the first servo motor 8. The first servo motor 8 drives the connecting rod 9 to rotate, thereby driving the mounting bracket 18 to rotate. During this process, start the second servo motor 14, which drives the connected rotating bracket 15 to rotate. The gear 17 on the same side of the rotating bracket 15 rotates synchronously, thereby driving the two rotating brackets 15 to move at the same speed and in opposite directions, so that the two insertion rods 16 contact each other and form a cylinder with a conical head.

[0095] S5: Activate the second electric push rod 13. The extension of the second electric push rod 13 will cause the mounting plate 19 and the moving frame 21 to move upward, so that the topmost glove comes into contact with the moving plate 26. During this process, activate the third electric push rod 20 to retract, which will cause the moving frame 21 to move horizontally, so that the opening of the glove exceeds the moving plate 26, allowing the insertion rod 16 to be inserted into the opening of the glove.

[0096] S6: Reactivating the third electric push rod 20 will cause the moving frame 21 to move horizontally, allowing the insertion rod 16 to be inserted into the opening of the glove.

[0097] S7: Start the second servo motor 14, which drives the connected rotating frame 15 to rotate. The gear 17 on the same side of the rotating frame 15 rotates synchronously, thereby driving the two rotating frames 15 to move at the same speed and in opposite directions, thus completing the operation of opening the glove.

[0098] S8: The second electric push rod 13 is activated to retract and the third electric push rod 20 is activated to extend, thereby resetting the moving plate 26 and the moving frame 21.

[0099] S9: Start the first servo motor 8. The first servo motor 8 drives the connecting rod 9 to rotate, thereby driving the mounting bracket 18 to rotate, so that the glove is put on the protrusion on one side of the housing 1. At this time, the glove is connected to the inlet 4.

[0100] S10: Start the linear motor 5. The linear motor 5 will drive the circular clamp 7 to move horizontally, so that the circular clamp 7 and the protrusion on the inner wall of the housing 1 together clamp the glove, so that the glove and the housing 1 are sealed.

[0101] S11: Start the air pump. The air pump will extract the air from the housing 1, so that the housing 1 is under negative pressure, which will make the glove fully open. At this time, you can put your hand into the fully open glove. The wearer's hand is inserted into the glove through the inlet 4.

[0102] S12: Start the linear motor 5. The linear motor 5 will drive the circular clamp 7 to move horizontally, so that the circular clamp 7 is reset. The hand can be pulled out from the inlet 4 and the operation of the air pump will be stopped, thus completing the glove putting on.

[0103] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0104] Example 2: To further optimize the glove feeding process, this example, based on the application of the above-mentioned device, can also provide an automatic feeding mode for one-piece gloves, with the following specific improvements:

[0105] The feeding module includes a conveyor belt mechanism located on the inner bottom wall of the housing 1. Positioning pins that mate with glove positioning holes are spaced apart on the surface of the conveyor belt. A ring-shaped cutting blade driven by a servo motor is installed at the end of the conveyor belt. An arc-shaped limiting groove is provided on the top of the mounting plate 19 to align with the conveyor belt outlet. The one-piece gloves utilize a pre-fabricated roll material structure, with gloves connected by easily tearable, one-piece molded connectors. Each connector has a 5mm diameter positioning hole at its center.

[0106] Workflow optimization:

[0107] 1. Install the roll of one-piece gloves onto the feeding shaft of the conveyor belt mechanism, so that the positioning hole of the first glove mates with the positioning pin at the beginning of the conveyor belt, and the opening end of the glove faces the direction of the limiting groove.

[0108] 2. The control system starts the conveyor belt. When the positioning hole of the glove connection is fitted into the positioning pin of the work station, the photoelectric sensor triggers the conveyor belt to stop. At the same time, the second electric push rod 13 is started to drive the limit groove to rise, so that the opening end of the glove is aligned with the conical insertion rod 16.

[0109] 3. The negative pressure suction device creates a slight negative pressure (-5kPa) inside the glove through the suction tube 6, which causes the glove opening to open naturally, making it easier to insert the insertion rod 16 smoothly;

[0110] 4. When the vision sensor 3 detects that the glove is fully worn (the hand is inserted to a depth of more than 10cm), it sends a signal to the PLC controller, triggering the servo motor to drive the cutting blade to make a circumferential cut along the outer circumference of the positioning hole at 0.5mm, cutting off the connecting part to separate the single glove.

[0111] 5. The separated glove waste falls into the collection box through the waste channel at the end of the conveyor belt, and the conveyor belt automatically starts to transport the next glove.

[0112] This embodiment improves the success rate of feeding by using mechanical positioning with positioning holes and positioning pins (positioning accuracy ±0.1mm) and negative pressure assisted opening technology. Combined with the precise cutting of the ring cutter (cutting force adjustable from 3 to 5N), it realizes fully automated separation and feeding of one-piece gloves, which improves efficiency by 40% compared with traditional stacking feeding and reduces material waste.

[0113] Example 3: To enhance personalized adjustment and improve wearing comfort, this example adds a manual trigger separation mechanism to the above device. Specific improvements are as follows:

[0114] A pressure sensor switch (model: FSR402) is embedded in the inner wall of the inlet 4. The switch surface is covered with a 0.5mm thick silicone protective layer, and its signal output terminal is connected to the DI module of the PLC controller through a shielded wire. A miniature electromagnetic latch is installed inside the housing 1 below the inlet 4, and the latch trigger force is set to 2.5N.

[0115] Workflow optimization:

[0116] 1. When the wearer's hand is fully inside the glove (refer to step S11 in Example 1), the pressure switch inside the insertion port 4 (fixed inside the housing and connected to the PLC controller of the control system via a data control line) can be pressed by the index finger or thumb.

[0117] 2. After the pressure switch detects a continuous pressure of ≥1.5N (trigger time adjustable from 0.3 to 0.5 seconds), it sends a signal to the control system;

[0118] 3. The PLC controller immediately triggers the following linkage actions: the air pump stops running → the annular clamp 7 is reset under the drive of the linear motor 5 → the electromagnetic lock is de-energized and released;

[0119] 4. Under the action of elastic restoring force, the gloves separate from the insertion rod 16, and the wearer can independently remove both hands, and the device automatically enters the next cycle preparation state.

[0120] This embodiment uses a pressure-sensitive switch to achieve subjective judgment and immediate response of wearing comfort (response delay ≤ 0.2 seconds). The mechanically assisted separation design of the electromagnetic lock ensures that the glove does not stick to the device and detaches without sticking. Compared with the pure electric control mode, the separation failure rate is reduced by 30%, which is especially suitable for medical personnel with different hand sizes and further improves the human-computer interaction of the device.

[0121] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
