Technical Field

[0001] The present invention relates to the technical field of nose bridge patch assembly, and more specifically, to a production device and a production method for nose bridge patch assembly. Background Art

[0002] The external magnetic nasal dilator is a new type of nasal auxiliary tool that works with magnetic ventilation nose strips (nose patches) to improve nasal ventilation. The nose patch is mainly composed of a sticker and a metal sheet set on the sticker. The magnetic nasal dilator absorbs the metal sheet to physically expand the nasal cavity, thereby achieving the effect of improving breathing.

[0003] Among them, metal sheets are usually arc-shaped, which can better fit the physiological structure of the nose to achieve the best expansion function. Due to the uneven shape of metal sheets, it is difficult to automatically sort and load them through conventional automated equipment like regular-shaped materials. At present, it is often necessary to rely on manual material sorting. Manual sorting of materials not only consumes a lot of manpower costs, but also has a relatively slow operation speed, which is difficult to meet the needs of large-scale, high-efficiency automated production.

[0004] The above shortcomings need to be improved. Summary of the invention

[0005] In order to solve or alleviate the problem of low production efficiency of magnetic ventilation nose strip patches in the above-mentioned prior art, the present invention provides a production device and a production method for assembling nose strip patches.

[0006] The technical solution of the present invention is as follows:

The conveying mechanism is used to convey release paper, on which stickers are arranged; the feeding mechanism is used to arrange metal sheets and supply the metal sheets to the patch mechanism; the patch mechanism is used to assemble the metal sheets on the stickers.

[0010] Furthermore, guide units are provided on both sides of the carrier plate, and the guide units include a connecting plate connected to the carrier plate, a limiting plate is provided on the connecting plate, and a guide groove is provided between the connecting plate and the limiting plate, and the guide groove is used to limit the side position of the release paper.

[0011] Furthermore, the feeding mechanism includes a spiral disk, on which a spiral channel is provided, and the width of the spiral channel gradually decreases from bottom to top, so as to screen metal sheets in the correct direction.

[0012] Furthermore, the feeding mechanism includes a vibrating plate, the vibrating plate includes a plurality of material dividing channels, the vibrating plate is provided with a material dividing unit on one side of the material dividing channel, the material dividing unit includes a material taking plate corresponding to the material dividing channels one by one, and is used to take materials from each of the material dividing channels.

[0013] Furthermore, the feeding mechanism includes a turning unit, and the turning unit is used to turn over the metal sheet.

[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

"Multiple" means two or more, unless otherwise clearly and specifically defined. "Several" means one or more, unless otherwise clearly and specifically defined.

[0034] like Figure 2 and Figure 8 As shown, a production device for assembling nose bridge stickers described in one embodiment of the present invention includes a conveying mechanism 1, a feeding mechanism 2, and a patch mechanism 3. The conveying mechanism 1 is used to convey a release paper 6, on which a sticker 7 is arranged; the feeding mechanism 2 is used to arrange metal sheets 5 and supply the metal sheets 5 to the patch mechanism 3; the patch mechanism 3 is used to assemble the metal sheets 5 on the sticker 7.

[0035] During production, the conveying mechanism 1 conveys the release paper 6 with the sticker 7 pre-set to the working position, and the feeding mechanism 2 adjusts the metal sheet 5 to the correct placement direction and position. After the adjustment is completed, the metal sheet 5 is accurately supplied to the material picking place of the patch mechanism 3 according to the predetermined rhythm and position. The patch mechanism 3 grabs the metal sheet 5 at the material picking place, assembles the metal sheet 5 to the sticker 7 on the conveyed release paper 6, and completes the assembly process of the nose bridge patch. Subsequently, the assembled nose bridge patch continues to be conveyed forward with the release paper 6, and enters the subsequent packaging or other processing links, and this cycle is repeated to achieve continuous production of the nose bridge patch.

[0036] Specifically, a feeding mechanism 2 and a patch mechanism 3 are provided on both sides of the conveying mechanism 1. The feeding mechanism 2 can provide 5 metal sheets 5 at the same time, and the patch mechanism 3 can assemble 5 metal sheets 5 at a time. The two feeding mechanisms 2 take turns to feed, and the two patch mechanisms 3 take turns to assemble, thereby improving production efficiency. Since the stickers 7 on the release paper 6 are arranged in 5*6, each patch mechanism 3 has 3 rows of stickers. In actual application, the feeding quantity of the feeding mechanism 2 and the working area of ​​the patch mechanism 3 can be adjusted according to the arrangement of the stickers 7.

[0037] The device arranges the direction and position of the metal sheet 5 through the feeding mechanism 2 to improve production efficiency. In traditional production, due to the uncertainty of the direction and position of the metal sheet 5, manual assembly is time-consuming, labor-intensive and error-prone. Through automated equipment, the production speed is accelerated to meet the needs of mass production. At the same time, precise arrangement allows the patch mechanism 3 to assemble more stably and accurately, reducing the defective rate and further improving the consistency and quality stability of the product. From a cost perspective, automated operation not only greatly reduces labor costs, but also reduces material waste due to the reduction in defective rates.

[0038] like Figure 3 As shown, in a preferred embodiment, the conveying mechanism 1 includes a carrier plate 101, a linear drive unit 102 is arranged below the carrier plate 101, the movable end of the linear drive unit 102 is connected to a movable clamping unit 103, and the movable clamping unit 103 is clamped on both sides of the release paper 6, so that the release paper 6 moves synchronously with the linear drive unit 102.

[0039] Specifically, the linear drive unit 102 is a linear motor. The movable clamping unit 103 includes a fixed clamping plate and a movable clamping plate, the movable clamping plate is connected to the piston rod of the cylinder, and the piston rod is extended to drive the fixed clamping plate and the movable clamping plate to move away from or close to each other, thereby loosening or clamping the release paper 6.

[0040] During production, the movable end of the linear drive unit 102 drives the movable clamping unit 103 connected thereto to move. Under the action of the control signal, the cylinder of the movable clamping unit 103 causes the piston rod to retract and retract. When the piston rod retracts, the movable clamping plate and the fixed clamping plate are close to each other, thereby tightly clamping the two sides of the release paper 6; when the piston rod is extended, the movable clamping plate and the fixed clamping plate move away from each other, loosening the release paper 6. When the release paper 6 needs to be transported, the cylinder controls the movable clamping unit 103 to clamp the release paper 6, and the linear motor drives the movable clamping unit 103, thereby driving the release paper 6 to move synchronously, and transporting the release paper 6 to the subsequent process position at a uniform speed.

[0041] There are holes for positioning on the edge of the release paper 6. The movable clamping unit 103 will stay at the hole position in front of the nose patch being assembled, clamp the release paper 6, and after the two workstations have attached the metal sheet 5, drag the release paper 6 forward and then return to the hole position in front of the nose patch being assembled. The infrared identifier on the carrier plate 101 will recognize the position of the hole and stop.

[0042] The linear motor drive has the characteristics of fast response speed and high positioning accuracy, which can ensure that the release paper 6 is accurately transported at the preset speed and position, and provides a basis for the precise operation of the subsequent feeding mechanism 2 and the patch mechanism 3. The movable clamping unit 103 controls the opening and closing of the clamping plate through the cylinder, which can flexibly and stably clamp or loosen the release paper 6, and ensure the stability of the release paper 6 during the transportation process.

[0043] like Figure 3 As shown, in a preferred embodiment, a fixed clamping unit 104 is provided on the carrier 101, and the fixed clamping unit 104 is clamped on both sides of the release paper 6, so that the relative position of the release paper 6 and the carrier 101 is fixed, and the stability during the explosive assembly of the metal sheet 5 is improved. The structural composition of the fixed clamping unit 104 is the same as that of the movable clamping unit 103.

[0044] When the nose patch is assembled, the piston rod of the fixed clamping unit 104 contracts, and the movable clamp moves toward the fixed clamp until it tightly clamps both sides of the release paper 6, ensuring that the relative position of the release paper 6 and the carrier 101 remains fixed. When the assembly is completed, the piston rod of the cylinder pushes the movable clamp away from the fixed clamp, loosens the release paper 6, and facilitates the delivery of the release paper 6.

[0045] The fixed clamping unit 104 provides a reliable clamping force, effectively preventing the release paper 6 from being displaced or shaken during the assembly process, so that the metal sheet 5 can be accurately assembled on the sticker 7 on the release paper 6, reducing the assembly deviation caused by the unstable position of the release paper 6 and improving the production yield.

[0046] like Figure 3 and Figure 4 As shown, in a preferred embodiment, guide units 105 are provided on both sides of the carrier 101, and the guide units 105 include a connecting plate 1051 connected to the carrier 101, a limiting plate 1052 is provided on the connecting plate 1051, and a guide groove 1053 is provided between the connecting plate 1051 and the limiting plate 1052, and the guide groove 1053 is used to limit the side position of the release paper 6.

[0047] When the release paper 6 moves forward as driven by the conveying mechanism 1 , the side edge of the release paper 6 is located in the guide groove 1053 . Under the restriction of the guide groove 1053 , the release paper 6 moves forward smoothly along the direction of the guide groove 1053 .

[0048] The setting of the guide unit 105 ensures the conveying stability of the release paper 6. The guide groove 1053 limits the side position of the release paper 6 so that the release paper 6 can be stably and accurately conveyed to the preset position, ensuring the precise assembly of the metal sheet 5.

[0049] like Figure 5 and Figure 6 As shown, in a preferred embodiment, the feeding mechanism 2 includes a spiral disk 201, and a spiral channel 2011 is provided on the spiral disk 201. The width of the spiral channel 2011 gradually decreases from bottom to top, and is used to screen the metal sheets 5 in the correct direction.

[0050] During loading, the randomly placed metal sheets 5 are poured into the bottom of the spiral disk 201. The metal sheets 5 rise from the bottom of the spiral disk 201 along the spiral channel 2011. During the rising process, due to the narrowing of the width of the spiral channel 2011, the side-by-side metal sheets 5 slide back to the bottom of the spiral disk 201. As the width further narrows, the metal sheets 5 with the wrong direction also slide back to the bottom of the spiral disk 201. The metal sheets 5 with the correct direction, that is, the metal sheets 5 with the convex surface facing upward, are transported out one by one at the discharge port of the spiral channel 2011.

[0051] By gradually changing the width of the spiral channel 2011, the direction and arrangement of the metal sheet 5 can be automatically screened without manual intervention, saving a lot of labor and time costs. The stable and efficient screening process ensures that the direction of the metal sheet 5 delivered to the patch mechanism 3 is uniform, providing the prerequisite for the subsequent accurate assembly of the metal sheet 5 to the sticker 7 on the release paper 6, effectively reducing the assembly failure and defective products caused by the wrong direction of the metal sheet 5, and improving the production yield of the product.

[0052] like Figure 5 As shown, in a preferred embodiment, the feeding mechanism 2 includes a vibration plate 202, the vibration plate 202 includes a plurality of material dividing forks 2021, the vibration plate 202 is provided with a material dividing unit 203 on one side of the material dividing forks 2021, and the material dividing unit 203 includes a material taking plate 2031 corresponding to the material dividing forks 2021, and is used to take materials from each material dividing fork 2021. The material taking plate 2031 is connected to the cylinder, and the cylinder drives the material taking plate 2031 to move horizontally.

[0053] The vibrating plate 202 starts to work, and the continuous vibration drives the metal sheet 5 to move continuously in the plate, and then disperse into multiple material distribution forks 2021 to provide multiple materials at the same time, and the metal sheet 5 is arranged in order in the forks. The cylinder drives the material collection plate 2031 to move horizontally. When the material collection plate 2031 is aligned with the material distribution fork 2021, the metal sheet 5 in the material distribution fork 2021 relies on the micro-vibration force of the vibrating plate 202 to move to the material collection plate 2031 to complete the material collection action. After the material collection is completed, the cylinder drives the material collection plate 2031 to move horizontally again, so that the material collection plate 2031 is misaligned with the material distribution fork 2021, and the material collection plate 2031 is against the material distribution fork 2021, effectively preventing the remaining material in the material distribution fork 2021 from falling, and preparing for the next material collection.

[0054] The vibration plate 202 is combined with the material distribution fork 2021 to efficiently disperse the metal sheet 5, creating good conditions for the patch mechanism 3 to pick up materials. By setting the material distribution unit 203, the accuracy and stability of material picking are ensured, and material confusion and blockage are avoided. The material distribution fork 2021 can provide multiple materials at the same time, and cooperate with the rapid material picking and transfer of the material picking plate 2031 to improve the material supply speed, meet the high-speed and continuous requirements of the production line for the metal sheet 5, and improve the overall production efficiency. After picking up materials, the material picking plate 2031 can be against the material distribution fork 2021 to prevent materials from falling, effectively manage materials, reduce material waste and loss, and ensure a stable and reliable production process.

[0055] like Figure 5 As shown, in a preferred embodiment, the feeding mechanism 2 includes a flip unit 204, and the flip unit 204 is used to flip the metal sheet 5. Specifically, the flip unit 204 includes a mounting plate, and a material pickup nozzle is arranged on the mounting plate. The material pickup nozzle corresponds to the metal sheet 5 on the material pickup tray 2031 one by one, and the mounting plate is connected to the motor output shaft.

[0056] When the material picking tray 2031 completes the material picking action with the metal sheet 5 and moves to a specific position, the flip unit 204 begins to work. The material picking nozzle on the mounting plate corresponds to the metal sheet 5 on the material picking tray 2031 one by one, and the material picking nozzle uses negative pressure to generate suction to absorb the metal sheet 5. Subsequently, the motor connected to the mounting plate receives a control signal and starts to operate, and the motor output shaft drives the mounting plate to flip 180 degrees. During the flipping process, the material picking nozzle always stably absorbs the metal sheet 5 to ensure that it does not fall. After the mounting plate is flipped into place, the metal sheet 5 is turned over. At this time, the material picking nozzle releases the suction force and releases the turned metal sheet 5 so that the patch mechanism 3 can be assembled.

[0057] like Figure 7 As shown, in a preferred embodiment, the patch mechanism 3 includes a transfer unit 301, and the movable end of the transfer unit 301 is connected to a material picking suction cup 302. The transfer unit 301 is a three-axis transfer device that can move accurately in the X, Y, and Z directions.

[0058] The movable end of the transfer unit 301 is connected to the material picking suction cup 302. After receiving the control command, the transfer unit 301 first cooperates in the X and Y axis directions to quickly move the material picking suction cup 302 to the top of the metal sheet 5. Then, the material picking suction cup 302 is driven to descend in the Z axis direction, and the material picking suction cup 302 sucks the metal sheet 5. After the metal sheet 5 is firmly sucked, the material picking suction cup 302 rises in the Z axis direction, and then the transfer unit 301 again moves the material picking suction cup 302 that has sucked the metal sheet 5 to the corresponding position of the sticker 7 on the release paper 6 through the cooperation of the X and Y axes. Finally, the material picking suction cup 302 is controlled to descend in the Z axis direction to accurately place the metal sheet 5 on the sticker 7, completing a patch operation, and the transfer unit 301 quickly prepares for the next material picking and patch operation.

[0059] The three-axis transfer device can flexibly and accurately control the position of the material picking suction cup 302 in three directions, so that the material picking suction cup 302 can quickly and accurately reach the position of the metal sheet 5 and the sticker 7, shortening the time of picking and pasting, and improving production efficiency. Accurate positioning and movement ensure that the metal sheet 5 can be assembled on the sticker 7, effectively reducing the production of defective products caused by deviation of the patch position, and improving product quality.

[0060] like Figure 1 As shown, in a preferred embodiment, a box body 4 is arranged outside the conveying mechanism 1 , the feeding mechanism 2 and the patch mechanism 3 , and an inspection door 401 and a controller 402 are arranged on the box body 4 .

[0061] During the operation of the equipment, the box 4 accommodates the conveying mechanism 1, the feeding mechanism 2 and the patch mechanism 3. The operator sends instructions to the equipment through the controller 402, and the controller 402 receives and interprets these instructions, and then transmits control signals to the conveying mechanism 1, the feeding mechanism 2 and the patch mechanism 3 respectively to coordinate the operation. When the equipment needs to be inspected or maintained, the operator opens the inspection door 401 on the box 4, enters the interior to inspect, repair or replace parts of each mechanism. After the inspection is completed, the inspection door 401 is closed, and the equipment is started again through the controller 402 to allow production to continue.

[0062] In this embodiment, the box 4 can effectively prevent personnel from accidentally touching the operating mechanism and avoid safety accidents. At the same time, it can prevent external dust, debris, etc. from entering the interior of the equipment, reduce equipment failures caused by foreign objects, extend the service life of the equipment, and prevent dust from contaminating the product. The inspection door 401 facilitates the maintenance and maintenance of the equipment, allowing staff to quickly enter the internal components of the equipment, shorten the inspection time, and improve the utilization rate of the equipment. The controller 402 realizes centralized control of the entire equipment, and the operator can flexibly adjust the equipment parameters according to production needs to improve the flexibility and adaptability of production.

[0063] like Fig. 9As shown, a production method for assembling a nose bridge patch described in one embodiment of the present invention is applicable to the above-mentioned production equipment for assembling a nose bridge patch, and comprises the following steps:

[0064] S1, the conveying mechanism 1 conveys the release paper 6 with the sticker 7 to a preset assembly position;

[0065] S2, placing the metal sheet 5 into the feeding mechanism 2, and the feeding mechanism 2 arranges the metal sheet 5;

[0066] S3, the patch mechanism 3 grabs the sorted metal sheet 5 and the sticker 7 for assembly.

[0067] In S1, the linear drive unit 102 drives the release paper 6 to move to the preset assembly position through the movable clamping unit 103, and then the movable clamping unit 103 releases the release paper 6, and the linear drive unit 102 drives the movable clamping unit 103 to reset and prepare for the next movement. At this time, the fixed clamping unit 104 clamps the release paper 6, and after the sticker 7 at the current position is assembled, the fixed clamping unit 104 is released, and the linear drive unit 102 drives the release paper 6 to move through the movable clamping unit 103.

[0068] In S2 , the spiral disk 201 conveys the disordered metal sheets 5 in an orderly manner, the vibrating disk 202 disperses the metal sheets 5 , the material taking unit divides the materials, and the flipping unit 204 flips the direction of the metal sheets 5 .

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
