Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical product production equipment, and more particularly to a processing equipment and a processing method for fabric tube sleeve molding and in-situ assembly. Background Art
[0002] Medical respiratory masks, especially those used for non-invasive positive pressure ventilation therapy, are usually worn by users with a special head strap that wraps around the patient's head and secures it to a specific position on the patient's face (such as the nose, mouth and nose, or the entire face) for treatment.
[0003] For example, a breathing mask with a gas transmission tube that also functions as a strap inevitably comes into contact with the skin during use. Therefore, a fabric sleeve is needed to enhance wearing comfort. Prior art offers a detachable fabric sleeve, a sheet-like structure that attaches and detaches via hooks and UBL fabric. This sleeve is an optional accessory for breathing masks, but its structure is simple and lacks a tight fit with the tube, impacting the overall visual appearance of the product.
[0004] In the prior art, there is also a fabric tube sleeve that matches the contour and size of the pipe and tightly covers the pipe locally. By superimposing two layers of fabric and ultrasonic welding and cutting, a tube sleeve with two welds is obtained. The contour curvature of the tube sleeve weld matches the contour curvature of the portion of the pipe to be covered on the respiratory mask, while the cross-sectional size of the tube sleeve is smaller than the cross-sectional size of the pipe. The fabric tube sleeve is then manually assembled onto the pipe of the respiratory mask using corresponding tooling. There are two problems with this process: (1) Due to the large friction resistance between the fabric and the pipe, the assembly efficiency is low, especially for pipes with large cross-sectional size changes; (2) The tube sleeve is easily damaged during the assembly process, resulting in a high defect rate.

[0048] The present invention will be further described below with reference to the accompanying drawings and examples.
[0049] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the invention can be combined interactively without conflicting with each other.
[0050] Reference Figures 1 to 3As shown, the present invention discloses a processing equipment for forming and in-situ assembly of a fabric tube sleeve. Specifically, the equipment includes a working platform 10 and an unwinding mechanism 20, a stretching mechanism 30, and an ultrasonic welding and cutting mechanism arranged above the working platform 10. In this embodiment, the ultrasonic welding and cutting mechanism is composed of a welding and cutting component 50 and an ultrasonic component 60; the working platform 10 is arranged above the frame 101, and the unwinding mechanism 20 is located at one end of the working platform 10. The unwinding mechanism 20 is used to provide fabric to the stretching mechanism 30. The unwinding mechanism 20 includes a material tray shaft and a motor for driving the material tray shaft to rotate. This structure is relatively common in the prior art, so its structure is no longer described in detail in this embodiment.
[0051] Combine Figure 3 As shown, the welding and cutting assembly 50 is disposed above the stretching mechanism 30, and the ultrasonic assembly 60 is located below the stretching mechanism 30. The welding and cutting assembly 50 and the ultrasonic assembly 60 cooperate to achieve ultrasonic welding and cutting of the fabric. It should be noted that the positions of the ultrasonic assembly 50 and the welding and cutting assembly 60 can be swapped to still achieve ultrasonic welding and cutting of the fabric. In this embodiment, the welding and cutting assembly 50 includes a welding and cutting cylinder 501, a welding and cutting fixing plate 502, a cutter holder 503, and a cutter. The welding and cutting cylinder 501 is fixedly mounted on the welding and cutting fixing plate 502, and the cutter is fixed on the cutter holder 503. The cutter holder 503 is connected to the cylinder rod of the welding and cutting cylinder 501 and moves up and down driven by the welding and cutting cylinder 501. The up and down movement of the cutter, through the combined action of the ultrasonic assembly 60 and the welding and cutting assembly 50, achieves welding and cutting of the fabric. The ultrasonic assembly 60 includes a transducer 601 and a steel mold 602. The steel mold 602 is fixed to the top of the transducer 601. The stretched fabric passes between the steel mold 602 and the cutter. When the cutter moves down to the working position, the blade contacts the fabric. Through the combined action of the transducer 601 and the steel mold 602, ultrasonic welding is achieved at the cross section of the fabric.
[0052] Through the above-described structure, the fabric provided by the unwinding mechanism 20 enters the stretching mechanism 30, where it is wrapped around the tubular member and placed in a stretched state. The fabric wrapped around the tubular member is then ultrasonically welded and cut by the welding and cutting assembly 50 and the ultrasonic assembly 60, completing the fabric welding and cutting process. The presence of the stretching mechanism 30 allows for automated welding and cutting of fabric coverings for flexible tubular members with specific curves and curvatures, forming fabric sleeves and completing in-situ assembly. This entire process requires no human intervention and is highly automated. Furthermore, upon completion of the sleeve, it is simultaneously placed on the tubular member in-situ, eliminating the need for secondary assembly and streamlining the process.
[0053] Reference Figure 4 、 Figure 5As shown, for the stretching mechanism 30, the present invention provides a specific embodiment, the function of the mechanism is to position, fix, and stretch the tubular member, carry the positioning fixture and the horizontal movement of the tubular member on the positioning fixture, realize the wrapping of the tubular member by the fabric and the pre-stretching of the wrapped section of fabric, specifically, the mechanism includes an upper feed shaft 301, a lower feed shaft 302, a positioning fixture 40, a pressing mechanism 304 and a material transport motor assembly 305; the upper feed shaft 301 is located above the lower feed shaft 302, the fabric is located on one side of the upper feed shaft 301, and extends in the direction from the upper feed shaft 301 to the lower feed shaft 302; refer to Figure 5 As shown, the two ends of the upper feeding shaft 301 are rotatably mounted on the bottom end of an upper feeding shaft mounting block 3011, and the two ends of the lower feeding shaft 302 are rotatably mounted on the top end of a lower feeding shaft mounting block 3021. An upper pressing mounting plate 3012 is also fixedly provided on the upper feeding shaft mounting block 3011.
[0054] Further, combined Figure 4 As shown, the positioning fixture 40 includes a cloth pulling rod 405, and the material transporting motor assembly 305 is arranged on one side of the positioning fixture 40. The material transporting motor assembly 305 is used to drive the positioning fixture 40 to move horizontally, so that the fixture 40 carries the tubular part and passes between the upper material passing shaft 301 and the lower material passing shaft 302, driving the cloth 306 to wrap the tubular part; the pressing mechanism 304 is arranged on one side of the upper material passing shaft 301 and the lower material passing shaft 302, and is used to realize the compression of the two ends of the cloth 306 wrapped around the tubular part after the cloth 306 wraps the tubular part; in this embodiment, combined with Figure 5 The pressing mechanism 304 includes an upper pressing assembly 3041 and a lower pressing assembly 3042 having the same structure. In this embodiment, the structure of the upper pressing assembly 3041 is described in detail. The upper pressing assembly 3041 includes a pressing cylinder 3043 and a pressing plate 3044. The pressing plate 3044 is connected to the cylinder rod of the pressing cylinder 3043. The pressing cylinder 3043 is driven to press the cloth 306. Similarly, the lower pressing assembly 3042 includes a pressing cylinder 3046 and a pressing plate 3047. The pressing plate 3047 is connected to the cylinder rod of the pressing cylinder 3046. The pressing cylinder 3046 is driven to press the cloth 306. In addition, a cloth pressing plate 3045 is fixedly provided on the upper material feeding shaft mounting block 3011, and the cloth pressing plate 3044 presses the cloth 306 on the cloth pressing plate 3045; similarly, a cloth pressing plate 3048 is also fixedly provided on the lower material feeding shaft mounting block 3021, and the cloth pressing plate 3047 presses the cloth 306 on the cloth pressing plate 3048.
[0055] In the above embodiment, the upper pressing mounting plate 3012 is fixedly connected to the upper feed shaft mounting block 3011, and two pressing cylinders 3043 are installed side by side on the upper pressing mounting plate 3012, and the upper pressing plate 3044 is connected to the cylinder rods of the two pressing cylinders 3043. By driving the pressing cylinders 3043, the cloth 306 can be pressed tightly on the cloth pressing plate 3045 of the upper feed shaft mounting block 3011; similarly, the lower pressing assembly 3042 also includes two pressing cylinders 3043, and the lower pressing plate 3044 is connected to the cylinder rods of the two pressing cylinders 3043, which can drive the lower pressing plate 3044 to press the cloth 306 tightly on the cloth pressing plate 3045 of the lower feed shaft mounting block 3021.
[0056] Through the above structure, when the positioning fixture 40 is driven by the material transport motor assembly 305 to move horizontally from the initial position toward the direction of the cloth, after the cloth pulling rod 405 and the tubular member pass through between the upper material passing shaft 301 and the lower material passing shaft 302, the cloth 306 wraps the tubular member, and then the cloth 306 is pressed by the pressing mechanism 304; thereafter, the cloth pulling rod 405 is driven to move by the material transport motor assembly 305, acting on the cloth 306 to achieve pre-stretching of the cloth 306, and after welding and cutting, the cloth 306 forms a tubular fabric sleeve, and the formed fabric sleeve is realized in situ on the tubular member. Because the fabric is pre-stretched before welding and cutting, the resulting fabric sleeve shrinks, allowing it to fit tightly over the tubular component and automatically adapt to changes in the tubular component's cross-sectional dimensions and profile curvature. Therefore, the present invention enables automated mass production of the fabric sleeve, improving automation and significantly reducing manufacturing costs and defect rates. The fabric sleeve can be formed and wrapped around a curved or curved flexible tubular component in situ in a single step. The sleeve fits snugly to the tubular component, eliminating the need for secondary assembly, simplifying the process and significantly reducing manufacturing costs. The welded fabric has only a single weld seam, enhancing the wearing comfort and overall visual appearance of the respiratory mask.
[0057] For the material transport motor assembly 305, Figure 4 As shown, the present invention provides a specific embodiment, the material transport motor assembly 305 includes a material transport motor 3051, a rotating screw 3052 and a screw slider 3053; one end of the rotating screw 3052 is connected to the output end of the material transport motor 3051, the screw slider 3053 is arranged on the rotating screw 3052, and a screw connecting block 409 is fixedly provided on the screw slider 3053, the screw connecting block 409 is connected to the positioning fixture 40, and the positioning fixture 40 is slidably installed on the first slide rail 3054.
[0058] Combine Figure 6 、 Figure 7As shown, for the above-mentioned positioning fixture 40, the present invention provides a specific embodiment, the positioning fixture 40 includes a fixture positioning plate 401, a first fixture mounting block 402, a second fixture mounting block 403 and a product positioning block 404, wherein the two ends of the fixture positioning plate 401 extend in the vertical direction to form two symmetrical extension ends 406, and its structure is as follows Figure 3 As shown, a square notch is formed at the center of the jig positioning plate 401; the first jig mounting block 402 and the second jig mounting block 403 are relatively and detachably fixed on the jig positioning plate 401. In this solution, the first jig mounting block 402 and the second jig mounting block 403 are respectively fixed on the two extension ends 406, and the first jig mounting block 402 is provided with a jig body 407 for positioning one end of the tubular member. In this embodiment, the jig body 407 is provided with a card slot, through which one end of the tubular member is fixed and positioned; it can be understood that the cross-sectional shape of the tubular member is similar to the card slot, and its end is slightly larger, so it can be just stuck in the card slot of the jig body 407. The product positioning block 404 is fixed on the second fixture mounting block 403. The product positioning block 404 is used to position the other end of the tubular member. In this embodiment, the product positioning block 404 is provided with an upward protruding bump, and the side wall of the tubular member is provided with a ring-shaped fastener, which is just buckled on the bump of the product positioning block 404.
[0059] In addition, the cloth-pulling rod 405 is disposed between the first jig mounting block 402 and the second jig mounting block 403. In this embodiment, a cloth-pulling rod mounting block 408 is further disposed on the second jig mounting block 403. One end of the cloth-pulling rod 405 is fixed to the cloth-pulling rod mounting block 408, while the other end of the cloth-pulling rod 405 faces the jig body 407, with a gap reserved between the cloth-pulling rod 405 and the jig body 407. It should be noted that after the tubular member is mounted on the positioning jig 40, the tubular member can pass through the cloth-pulling rod 405. When the tubular member is stretching the fabric, the cloth-pulling rod 405 can provide support to prevent deformation of the tubular member. In another embodiment, the cloth-pulling rod 405 is located at the outer front edge of the tubular member. When the tubular member is stretching the fabric, the cloth-pulling rod 405 can provide support to prevent deformation of the tubular member. In another embodiment, the cloth-pulling rod 405 can be removed.
[0060] Combine Figure 12 As shown in FIG, it is a schematic structural diagram of a tubular member with a certain curve and arc in the above embodiment. The tubular member 100 is hollow and flexible and is used to be installed on a medical breathing mask as a pipeline for transmitting positive pressure air flow and also plays a role in fixing the mask. Figure 13 As shown, the portion of the tubular member 100 that contacts the human skin needs to be wrapped with cloth to form an annular fabric sleeve 200 on the tubular member 100. Figure 14As shown in FIG. 1 , a partial structural diagram of the tubular member 100 is shown. When wrapping the cloth, the bent portion needs to be straightened before wrapping the cloth to form a Figure 13 The structure shown; combined Figure 6 As shown, one end 1001 of the tubular member 100 is clamped on the fixture body 407, and the other end 1002 of the tubular member 100 is sleeved on the product positioning block 404. At this time, the structure of the tubular member 100 is as shown in FIG. Figure 14 As shown by the dotted line. Through the above structure, the positioning and stretching of the tubular part can be achieved through the jig body 407 and the product positioning block 404. When the tubular part has a certain degree of curvature, the tubular part can also be straightened, so as to facilitate the welding and cutting of the fabric sleeve on the tubular part, which is conducive to the automation of the welding and cutting of the fabric sleeve. In addition, the jig positioning plate 401 is provided with a positioning hole 410, and the first jig mounting block 402 and the second jig mounting block 403 are provided with positioning columns below. Therefore, the first jig mounting block 402 and the second jig mounting block 403 can be disassembled and installed from the jig positioning plate 401 to facilitate assembly line processing. Figure 6 As shown, the screw connecting block 409 is fixed to one side of the fixture positioning plate 401 to drive the fixture positioning plate 401 to reciprocate.
[0061] Reference Figure 2 、 Figure 8 as well as Figure 9 As shown, the fabric tube sleeve forming and in-situ assembly processing equipment also includes a positioning carrier 70 and a material removal module 80 disposed on the work platform 10. The positioning carrier 70 is located on one side of the material removal module 80 and is used to secure the first fixture mounting block 402 and the second fixture mounting block 403. The positioning carrier 70 includes a rodless cylinder 701 and a fixture placement plate 702. The first fixture mounting block 402 and the second fixture mounting block 403 are detachably mounted on the fixture placement plate 702. The rodless cylinder 701 is located below the work platform 10. A waste recovery mechanism (labeled in the figure) is also provided below the work platform 10. The waste recovery mechanism continuously recovers waste fabric after welding and cutting, and also provides power for the movement of the fabric.
[0062] Reference Figure 8As shown, the retrieving module 80 is used to remove the first fixture mounting block 402 and the second fixture mounting block 403 from the fixture positioning plate 401 and then transfer them to the positioning fixture. In this embodiment, the retrieving module 80 includes a linear motor module 801, a first lifting cylinder 802, a retrieving cylinder plate 803, and a gripper cylinder 804. The first lifting cylinder 802 is connected to the output end of the linear motor module 801 and is driven by the linear motor module 801 to reciprocate. The linear motor module 801 is a common linear motor in the prior art, and its internal structure is not described in this solution. The picking cylinder plate 803 is connected to the cylinder rod of the first lifting cylinder, and the clamping cylinder 804 is fixed on the picking cylinder plate 803. The clamping cylinder 804 is driven by the first lifting cylinder 802 to realize the lifting movement. The clamping cylinder 804 has a pneumatic clamping jaw 805. Through the drive of the clamping jaw cylinder 804, the pneumatic clamping jaw 805 is opened or closed to realize the transfer of the first fixture mounting block 402 and the second fixture mounting block 403.
[0063] Therefore, it can be understood that when the jig placement plate 702 is in the initial position, the tubular part to be processed is installed on the first jig mounting block 402 and the second jig mounting block 403. Thereafter, the rodless cylinder 701 drives the jig placement plate 702 to move horizontally to the bottom of the pneumatic clamp of the material picking module 80. Under the action of the material picking module 80, the first jig mounting block 402 and the second jig mounting block 403 are removed. Then, the material picking module carries the jig and the tubular part, and moves to the position where it docks with the positioning jig under the drive of the linear module, and the jig is installed on the jig positioning plate of the positioning jig 40, thereby realizing continuous processing.

[0065] The present invention also provides a fabric sleeve forming and in-situ assembly processing method, referring to Figure 11 As shown, the method is implemented by relying on the above-mentioned fabric tube sleeve forming and in-situ assembly processing equipment. Specifically, the processing method includes the following steps:
[0066] S10, fixing the tubular member, installing the tubular member on a positioning jig, and straightening the bent or curved tubular member by the positioning jig;
[0067] Combine Figure 6 As shown, one end of the tubular member is clamped on the jig body 407, and the other end of the tubular member is sleeved on the product positioning block 404. The jig body 407 and the product positioning block 404 stretch the tubular member, and the bent or curved tubular member is straightened to facilitate subsequent processes. The positioning jig includes a cloth pulling rod. After the tubular member is fixed to the positioning jig, it is located on one side of the cloth pulling rod.
[0068] S20, the fabric wraps the tubular member, the transport motor assembly drives the positioning fixture to translate in a first direction to translate the tubular member in the first direction, and the fabric wraps the tubular member; the fabric moves in a second direction, and the first direction is perpendicular to the second direction;
[0069] In this embodiment, combined with Figure 4 As shown, the upper feed shaft 301 and the lower feed shaft 302 are arranged in a vertical direction, and the cloth is transmitted from top to bottom (i.e., perpendicular to the horizontal plane) and is located on one side of the upper feed shaft 301 and the lower feed shaft 302. When the cloth pulling rod drives the tubular member to translate horizontally, it drives the cloth to pass between the upper feed shaft 301 and the lower feed shaft 302, achieving the cloth folding. At this time, the cloth is wrapped around the tubular member; and when the cloth wraps around the tubular member, it also wraps around the cloth pulling rod.
[0070] S30, stretching the fabric: the fabric wraps around the tubular member to form an opening, and after the fabric at both ends of the opening are pressed tightly, the positioning fixture continues to move to achieve fabric stretching;
[0071] Combine Figure 5 As shown, the upper pressing assembly 3041 realizes the pressing of the upper end of the cloth opening, and the lower pressing assembly 3042 realizes the pressing of the lower end of the cloth opening. When the positioning fixture drives the tubular member to move further to the right, the cloth is stretched.
[0072] S40, ultrasonic welding and cutting, the stretched fabric is welded and cut by an ultrasonic welding and cutting mechanism; after the fabric is welded and cut, the fabric wrapped around the tubular member forms a fabric tube sleeve with a ring-shaped longitudinal section, and the fabrics at both ends of the opening are connected by welding and cutting.
[0073] Combine Figure 3As shown, the welding and cutting cylinder drives the cutter seat 503 downward, and the cutter on the cutter seat 503 cuts the fabric. The ultrasonic welding and cutting mechanism consists of an ultrasonic component and a welding and cutting component 50. The steel mold of the ultrasonic component is located below the fabric to achieve welding of the fabric. Therefore, through the cooperation of the welding and cutting component 50 and the ultrasonic component 60, ultrasonic welding and cutting of the fabric are achieved. At the same time, after the fabric is welded and cut, the fabric wrapped around the tubular member forms a fabric tube with a circular longitudinal cross-section. The fabric at the two open ends is connected by welding and cutting. This method connects the discarded fabric and the unwelded fabric. The waste recycling device can drive the fabric to continue moving, facilitating the next welding and cutting of the fabric. This can achieve continuous roll-to-roll processing and waste recycling. It is very convenient and fast, and can effectively reduce material loss and improve material utilization.

Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
