Description

Technical Field

[0001] This invention relates to the field of cotton swab assembly and processing technology, and in particular to a cotton swab assembly and processing device and assembly and processing method. Background Technology

[0002] In the existing technology, the assembly equipment for medical cotton swabs is usually completed by manual loading and unloading and single-station lathe manufacturing, which has low processing efficiency. In addition, the operation of multiple lathes on an assembly line or by adjusting the sequence of machines leads to deviations in the tool and program settings between different lathes, resulting in low precision of the final product.

[0003] In addition, manual feeding is not suitable for small-sized medical cotton swabs with fast processing speed. In particular, it is not suitable for materials with different shapes and structures at multiple ends or materials that are specified to be processed at one end during the processing. Automatic feeding equipment with only transmission function is also not suitable, as it requires high positioning accuracy of the materials.

[0004] In summary, there is currently a lack of medical swab assembly equipment with high positioning accuracy and high processing efficiency. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a cotton swab assembly and processing device and method, aiming to improve the feeding efficiency of cotton swabs and the assembly and positioning accuracy between cotton swabs and cotton fibers.

[0006] The technical solution adopted in this invention is as follows:

[0007] This invention provides a cotton swab assembly and processing device, comprising:

[0008] A frame is connected to an automatic feeding device, which includes a first feeding mechanism for vertical conveying and a second feeding mechanism for horizontal conveying, wherein the outlet of the first feeding mechanism is connected to the inlet of the second feeding mechanism;

[0009] An assembly mechanism is provided at the output end of the second feeding mechanism. The assembly mechanism includes a fixed end and a movable end. An assembly gap is formed between the side of the movable end and the side of the fixed end. The side of the fixed end is provided with a plurality of clearance holes and a cotton board is attached to its surface. The side of the movable end is provided with a plurality of cutting parts, and the cutting parts correspond one-to-one with the clearance holes.

[0010] The clamping mechanism includes at least one chuck, with two protrusions spaced apart at the bottom of the chuck. Each protrusion has a clamping groove at its bottom. A transmission component is provided inside the clamping groove. The transmission components in the two clamping grooves are symmetrically arranged to horizontally clamp the cotton swab from the output end of the second feeding mechanism. The chuck is also provided with at least one set of nozzles.

[0011] A slide drive mechanism is used to set the clamping mechanism, so that the clamping mechanism moves horizontally and vertically, and transports the cotton swabs that are horizontally clamped by the transmission assembly to the assembly port.

[0012] The packaging mechanism, connected to the frame, includes storage tanks for storing and drying products and conveyor belts for conveying them.

[0013] The further technical solution is as follows:

[0014] The transmission assembly includes a fixed track and a transmission track arranged adjacent to each other. The fixed track is fixedly installed, and the transmission track can run in the forward or reverse direction.

[0015] The fixed track and the transmission track are respectively provided with a number of semi-circular holes. When the fixed track is running, the semi-circular holes on it and the semi-circular holes on the transmission track form a circular transmission hole that is distributed at intervals in the vertical direction on the adjacent surface.

[0016] The bottom of the drive track extends beyond the clamping groove;

[0017] The transmission holes of the transmission components in the two clamping grooves correspond one-to-one, forming clamping holes that clamp the cotton swabs from both ends respectively.

[0018] As the transmission track rotates, the semi-circular holes sequentially lift the cotton swabs from the output end of the second feeding mechanism, and through the clamping holes, arrange several cotton swabs at intervals in the vertical direction.

[0019] The upper and lower ends of each of the aforementioned transmission tracks are respectively wound around a transmission shaft that is spaced apart from the upper and lower ends, and the tracks run in the forward or reverse direction under the action of the transmission shaft.

[0020] The movable end is located at the end of the piston rod of the linear cylinder, and the linear cylinder is fixedly connected to the frame.

[0021] The cotton board is made of cotton and is assembled on the side of the fixed end, covering the clearance hole. The side of the fixed end is also provided with a fixing mold, and the clearance hole is set on the fixing mold. The side of the movable end is provided with an active mold for assembling the cutting component. The structure of the cutting component includes an arc-shaped groove and cutting edges located on both sides of the arc-shaped groove. The opening size of the arc-shaped groove is smaller than the radius of the clearance hole.

[0022] The bottom of the first feeding mechanism is fixedly connected to a chassis, and a spiral conveyor belt that can be conveyed in a vertical direction is fixedly connected inside the first feeding mechanism. The output end of the spiral conveyor belt is connected to the second feeding mechanism.

[0023] The second feeding mechanism is equipped with a vibratory feeder for linear conveying, and the surface height of the vibratory feeder gradually decreases along the conveying direction; baffles are provided on both sides of the vibratory feeder, and sensors are provided on the baffles.

[0024] The slide drive mechanism includes a support frame, which is movably connected to the frame along the horizontal Y-axis. A guide rail is provided on the vertical surface of the support frame along the horizontal X-axis. A linear module that slides along the guide rail is provided on the guide rail. The clamping mechanism is disposed on the two-axis linear module and can move in the vertical direction.

[0025] The storage tank is equipped with a vibrating conveyor plate with several air holes on its bottom surface. The bottom surface of the vibrating conveyor plate is inclined from high to low along the direction from the inlet to the outlet. Several conveying ports are provided at the outlet position, and one side of each conveying port is connected to the conveyor belt.

[0026] This invention provides a method for assembling and processing cotton swabs using the aforementioned cotton swab assembly and processing device, comprising:

[0027] The cotton swabs are fed from the first feeding mechanism to the second feeding mechanism, and then from the second feeding mechanism to the output end in a horizontal direction;

[0028] The chuck moves along the horizontal X-axis to above the assembly gap and then moves downward along the vertical Z-axis.

[0029] The transmission components in the two clamping grooves at the bottom of the chuck run forward and lift the cotton swabs horizontally from the output end of the second feeding mechanism from both ends. As the transmission components run forward, several horizontally positioned cotton swabs are arranged at intervals in the vertical direction, and then the transmission components stop running.

[0030] The slide drive mechanism drives the chuck to move horizontally along the Y-axis, so that the ends of each cotton swab stick are close to the cotton board. At this time, the ends of the cotton swab sticks correspond one-to-one with the clearance holes on the fixed end.

[0031] As the movable end moves closer to the fixed end, the assembly gap gradually narrows until the cutting part is pressed against the cotton board and corresponds one-to-one with the clearance holes.

[0032] As the moving end continues to move, the cutting component cuts the cotton board in the clearance hole, and at the same time the cut cotton is wrapped around the end of the cotton swab.

[0033] The moving end moves away from the fixed end, and the chuck moves up along the vertical Z-axis.

[0034] Spray water mist through the nozzle on the chuck to make the cotton wool stick tightly to the tip of the cotton swab;

[0035] The slide drive mechanism drives the chuck to move along the horizontal X-axis to above the packaging mechanism, and moves it down along the vertical Z-axis. The transmission component runs in the opposite direction, and the cotton swabs with cotton wool attached to their ends are placed in the storage slot in sequence.

[0036] The cotton swabs are dried in the storage tank and then conveyed to the delivery port;

[0037] The cotton swabs are fed from the inlet to the conveyor belt and then output by the conveyor belt.

[0038] The beneficial effects of this invention are as follows:

[0039] This invention enables automatic feeding, automatic clamping, and automatic assembly between cotton swabs and cotton fibers, improving the positioning accuracy of the assembly position and enabling the automatic assembly of several cotton swabs at one time, thus improving assembly efficiency.

[0040] This invention enables automatic clamping, accurate positioning, and rapid unloading of multiple cotton swabs after assembly by using a transmission component that operates in both forward and reverse directions.

[0041] This invention utilizes the cooperation of a fixed end and a moving end to cut the cotton board into the clearance hole using a cutting component. At the same time, the cut cotton is automatically wrapped around the end of the cotton swab, achieving automatic assembly with high efficiency.

[0042] The nozzles provided on the chuck of this invention can be used to spray water mist or air to fix cotton wool or blow away foreign objects.

[0043] Other features and advantages of the invention will be set forth in the following description or may be learned by practicing the invention. Attached Figure Description

[0051] The specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0052] See Figures 1 to 3 The cotton swab assembly and processing device of this embodiment includes:

[0053] The frame 3 is connected to an automatic feeding device, which includes a first feeding mechanism 1 for vertical conveying and a second feeding mechanism 2 for horizontal conveying. The outlet of the first feeding mechanism 1 is connected to the inlet of the second feeding mechanism 2.

[0054] An assembly mechanism is provided at the output end of the second feeding mechanism 2. The assembly mechanism includes a fixed end 230 and a movable end. An assembly gap is formed between the side of the movable end and the side of the fixed end 230. The side of the fixed end 230 is provided with a plurality of clearance holes 231, and a cotton board 10 is attached to its surface. The side of the movable end is provided with a plurality of cutting parts, and the cutting parts correspond one-to-one with the clearance holes 231.

[0055] The clamping mechanism includes at least one chuck 450, with two protrusions spaced apart at the bottom of the chuck 450. Each protrusion has a clamping groove 460 at its bottom, and a transmission component is provided inside the clamping groove 460. The transmission components in the two clamping grooves 460 are symmetrically arranged for horizontally clamping the cotton swab 11 from the output end of the second feeding mechanism 2. The chuck 450 is also provided with at least one set of nozzles 451.

[0056] The slide drive mechanism 4 is used to set the clamping mechanism, so that the clamping mechanism moves horizontally and vertically, and transports the cotton swab stick 11, which is horizontally clamped by the transmission component, to the assembly port.

[0057] The packaging mechanism, which is connected to the frame 3, includes a storage tank 5 for storing and drying products and a conveyor belt 520 for conveying products.

[0058] See Figure 1 and Figure 5 As shown, Figure 5 The perspective is Figure 1From the left-side view, the transmission assembly includes a fixed track 474 and a transmission track 472 arranged adjacently. The fixed track 474 is fixedly arranged, and the transmission track 472 can run in the forward or reverse direction.

[0059] The fixed track 474 and the transmission track 472 are respectively provided with a number of semi-circular holes 470. When the fixed track 474 is running, the semi-circular holes 470 on it and the semi-circular holes 470 on the transmission track 472 form a circular transmission hole 473 that is distributed vertically at intervals on adjacent surfaces.

[0060] The bottom of the drive track 472 extends out of the clamping groove 460;

[0061] The transmission holes 473 of the transmission components in the two clamping grooves 460 correspond one-to-one, forming clamping holes that clamp the cotton swab sticks 11 from both ends respectively.

[0062] As the transmission track 472 rotates, the semi-circular hole 470 sequentially lifts the cotton swabs 11 at the output end of the second feeding mechanism 2, and arranges several cotton swabs 11 at intervals in the vertical direction through the clamping holes.

[0063] Each drive track 472 is wound around the upper and lower ends of a drive shaft 471 that is spaced apart from the upper and lower ends, and runs in the forward or reverse direction under the action of the drive shaft 471.

[0064] Specifically, the radius of the transmission hole 473 is slightly larger than the radius of the cotton swab 11.

[0065] See Figure 6 , Figure 6 The perspective is Figure 1 The left-side view. The movable end is located at the end of the piston rod of the linear cylinder 240, and the linear cylinder 240 is fixedly connected to the frame 3. The cotton board 10 is made of cotton and is assembled on the side of the fixed end 230, covering the clearance hole 231. The side of the fixed end 230 is also provided with a fixing mold, and the clearance hole 231 is set on the fixing mold; see also Figure 4 , Figure 4 The perspective is Figure 1 The left-side view. The active mold 6 for assembling the cutting component is provided on the side of the active end. The structure of the cutting component includes an arc-shaped groove 611 and cutting edges 610 located on both sides of the arc-shaped groove 611. The opening size of the arc-shaped groove 611 is slightly smaller than the radius of the clearance hole 231.

[0066] Specifically, the cotton board 10 is movably connected to the fixed end 230 and can move along the horizontal X direction. After a batch is assembled, the cotton board 10 moves a distance along the horizontal X direction for the next assembly.

[0067] like Figure 1As shown, a chassis 110 is fixedly connected to the bottom of the first feeding mechanism 1, and a spiral conveyor belt that can be conveyed in the vertical direction is fixedly connected inside the first feeding mechanism 1. The output end of the spiral conveyor belt is connected to the second feeding mechanism 2.

[0068] like Figure 1 and Figure 2 As shown, the second feeding mechanism 2 is equipped with a vibratory feeder for linear conveying, the surface height of which gradually decreases along the conveying direction. Baffles 220 are provided on both sides of the vibratory feeder, and sensors 210 are mounted on the baffles 220. The baffles 220 prevent material from falling off during transport. The sensors 210 monitor whether the conveyed material experiences jamming or blockage due to uncontrollable factors.

[0069] like Figure 1 As shown, the slide drive mechanism 4 includes a support frame, which is movably connected to the frame 3 along the horizontal Y-axis. A guide rail 410 is provided on the vertical surface of the support frame along the horizontal X-axis. A linear module 440 is provided on the guide rail 410 and slides along it. A clamping mechanism is provided on the two-axis linear module 440 and can move in the vertical direction.

[0070] like Figure 1 As shown, nozzle 451 can be used to spray water mist or air.

[0071] like Figure 1 As shown, the storage tank 5 is equipped with a vibrating conveyor plate with several air holes on its bottom surface. The bottom surface of the vibrating conveyor plate is inclined from high to low along the direction from the inlet to the outlet. Several conveying ports 510 are provided at the outlet position, and a conveyor belt 520 is connected to one side of the conveying port 510.

[0072] This embodiment also provides a cotton swab assembly and processing method for a cotton swab assembly and processing device, including:

[0073] The cotton swab 11 is conveyed by the first feeding mechanism 1 to the second feeding mechanism 2, and then conveyed by the second feeding mechanism 2 to the output end in the horizontal direction;

[0074] The chuck 450 moves along the horizontal X-axis to above the assembly clearance and then moves downward along the vertical Z-axis.

[0075] The transmission components in the two clamping grooves 460 at the bottom of the chuck 450 run in the forward direction and lift the cotton swabs 11 from the output end of the second feeding mechanism 2 in a horizontal position from both ends. As the transmission components run in the forward direction, several horizontal cotton swabs 11 are arranged at intervals in the vertical direction, and then the transmission components stop running.

[0076] The slide drive mechanism 4 drives the chuck 450 to move horizontally along the Y-axis, so that the ends of each cotton swab stick 11 are close to the cotton board 10. At this time, the ends of the cotton swab stick 11 correspond one-to-one with the clearance holes 231 on the fixed end 230.

[0077] The movable end moves toward the fixed end 230, and the assembly gap gradually decreases until the cut part is close to the cotton board 10 and corresponds one-to-one with the clearance hole 231.

[0078] As the moving end continues to move, the cutting component cuts the cotton board 10 in the clearance hole 231, and at the same time the cut cotton is wrapped around the end of the cotton swab stick 11.

[0079] The movable end moves away from the fixed end 230, and the chuck 450 moves up along the vertical Z-axis.

[0080] Water mist is sprayed through the nozzle 451 on the chuck 450, so that the cotton wool adheres tightly to the end of the cotton swab 11.

[0081] The slide drive mechanism 4 drives the chuck 450 to move along the horizontal X-axis to the top of the packaging mechanism and move down along the vertical Z-axis. The transmission components run in the opposite direction, and the cotton swabs 11 with cotton wool at the end are placed in the storage tank 5 in sequence.

[0082] The cotton swab 11 is dried in the storage tank 5 and then conveyed to the conveying port 510;

[0083] The cotton swab 11 is output from the feed port 510 to the conveyor belt 520, and then from the conveyor belt 520 to the next work station.

[0084] like Figure 5 As shown, in this embodiment, the transmission track 472 of the transmission assembly has four semi-circular holes 470 on its side and one semi-circular hole 470 on its bottom. The fixed track 474 is fixedly installed. The transmission track 472 runs in the forward (clockwise) or reverse (counterclockwise) direction under the action of the transmission shaft 471. The specific working principle of the transmission assembly is as follows:

[0085] When the drive track 472 is running in the forward direction, the semi-circular hole 470 at the bottom continuously lifts the cotton swab stick 11 and conveys it to the left. When it moves to be aligned with the semi-circular hole 470 on the left side of the fixed track 474, the four cotton swab sticks 11 are respectively located in the four drive holes 473, and then the drive track 472 stops running.

[0086] When the drive track 472 runs in reverse, the assembled cotton swab 11 is carried by the drive track 472 to the right. When the semi-circular hole 470 moves to the bottom, the cotton swab 11 falls out of it.

[0087] Furthermore, if foreign objects such as lint or debris remain in the chuck 450, they can be blown away by air jets from the nozzle 451.

[0088] It will be understood by those skilled in the art that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
