Description

Technical Field

[0001] This invention belongs to the field of automation equipment technology, and in particular relates to a fully automated manufacturing and packaging equipment and process for medical polymer dressing products. Background Technology

[0002] In the medical and skincare fields, polymeric wet compress products (especially gel-textured products with specific shapes) are increasingly widely used. The manufacturing process for these products has long relied on extensive manual labor or semi-automated equipment, resulting in low production efficiency, high labor costs, and difficulty in meeting the demands of large-scale, standardized production.

[0003] Traditional wet dressing manufacturing processes typically involve multiple discrete steps: first, the high-moisture raw materials need to be dehydrated to achieve the designed thickness and weight; then, the large substrate needs to be cut into smaller pieces of specific shapes and sizes; finally, they are individually bagged and sealed. These steps are often completed by different equipment, and the transfer of materials between different workstations relies heavily on manual operation. This not only introduces the risk of personnel contaminating the product but also results in poor continuity and slow pace of the entire production process.

[0004] More importantly, this human-driven, discrete production model severely restricts the stability and consistency of product quality. On the one hand, manual extrusion and dehydration makes it difficult to precisely control pressure and thickness, easily leading to uneven product thickness, large differences in unit weight, and unstable quality. It also poses a risk of cracking or damaging the product. On the other hand, manual cutting or traditional die-cutting easily results in uneven product edges, poor dimensional accuracy, and deformation or damage when transferring soft, sticky gel products. Furthermore, due to the lack of online quality monitoring methods, issues such as dimensional defects in cut products, foreign matter contamination during packaging, and weight deviations in the final product can usually only be addressed through random sampling at the final stage. Complete inspection and timely removal are impossible, posing potential risks to the safety and reliability of the final product.

[0005] Currently, no existing technology provides automated equipment to complete the production and packaging of the aforementioned wet dressing products. Therefore, the industry urgently needs to develop automated equipment that integrates the entire process of wet dressing production and packaging to address the technical bottlenecks of high reliance on manual labor, low production efficiency, unstable product quality, and lack of comprehensive quality monitoring in existing technologies.

[0020] Compared with existing technologies, the beneficial effects of this invention's fully automated manufacturing and packaging equipment and process for medical polymer dressings are as follows: By integrating a multi-axis robot, a precision transfer mechanism, an extrusion and dehydration and die-cutting mechanism, and a vision and weighing detection system, a fully automated production line is constructed. This successfully solves the problems of reliance on manual labor, low efficiency, and poor quality consistency in the production of medical polymer wet dressings. It achieves fully automated, high-precision, and high-quality production throughout the entire process, from wet dressing product feeding, comprehensive control of moisture content and product size, cutting to packaging and inspection. Specifically,

[0021] (1) Fully automated and efficient production has been achieved: Through the coordinated cooperation of the first and second handling mechanisms and multiple material supply, receiving and transfer mechanisms, the entire process of automated continuous production from raw material supply, extrusion and dehydration, die cutting and slicing to final packaging and unloading has been achieved, which has greatly reduced manual intervention and improved production efficiency.

[0022] (2) Ensures consistency of product moisture content and thickness: The wet dressing product is precisely squeezed and dehydrated by a special moisture content control mechanism. Specifically, the squeezing pressure, squeezing time, descent height and position parameters and squeezing speed parameters of the dehydration plate are controlled. Through the synergistic effect of the above parameters, the moisture content of the product can be precisely controlled to meet the set moisture content range requirements. At the same time, it can effectively prevent the product from cracking or being damaged, improve the product yield to achieve the set moisture content and meet the product design requirements. The roller smoothing module is used to ensure the product is flat, thereby effectively controlling the thickness and weight per unit area of ​​the final product and ensuring the uniformity and stability of product quality. Combined with the weighing and testing after packaging, it further ensures that the quality of the final output product meets the design requirements.

[0023] (3) Improved cutting accuracy and edge quality: Before cutting, the die-cutting mechanism rolls and smooths the material and uses a cutting die for precise cutting, while removing excess scraps. This series of operations ensures that the small pieces of the product after cutting are accurate in size and neat in edge, meeting the appearance requirements of medical products.

[0024] (4) A complete quality closed-loop control has been constructed: the visual inspection mechanism integrated into the production line screens the product size and foreign objects, the weighing inspection mechanism inspects the weight of the final product, and is linked with the automatic rejection mechanism to identify and separate unqualified products in a timely manner, thereby realizing quality monitoring and assurance in the production process;

[0025] (5) Improved the versatility of the equipment, making it suitable for dehydration, cutting and packaging of various sizes of wet dressing products. Attached Figure Description

It supplies wet dressings, squeezes and removes water to achieve the set moisture content, cuts the wet dressings to the designed dimensions, seals and packages the wet dressings, and automatically detects the products, thus achieving fully automated manufacturing and packaging of wet dressings. The wet dressings in this embodiment are polymer dressings with specific shapes and can be used in medical aesthetics, personal care, and medical devices.

[0054] This embodiment discloses a fully automated manufacturing and packaging equipment 100 for medical polymer dressings, including a first conveying mechanism 1 and a second conveying mechanism 2; a first feeding mechanism 3 and a second feeding mechanism 4, both located within the working range of the first conveying mechanism 1 and used for supplying wet dressing products; a moisture content control mechanism 5 for squeezing and dewatering the wet dressing products; a first receiving and transferring mechanism 6 at a first receiving position 80 that receives material from the first conveying mechanism 1 and moves it below the moisture content control mechanism 5; a die-cutting mechanism 7 located on one side of the moisture content control mechanism 5 and used for cutting a wet dressing product into multiple smaller pieces; a second receiving and transferring mechanism 8 at a second receiving position 90 that receives material from the first conveying mechanism 1 and moves it below the die-cutting mechanism 7; and a third receiving position 110 that receives material from the first conveying mechanism 1. The system includes a third receiving and transfer mechanism 9 that receives materials from the first conveying mechanism 1 and moves them along the Y direction to the material supply position of the second conveying mechanism 2; a first visual inspection mechanism 10 that performs visual inspection on the cut wet dressing product at the third receiving position 110; a heat sealing mechanism 20 that is located on one side of the die-cutting mechanism 7 in the Y direction and encapsulates the small wet dressing pieces in a packaging bag formed by heat sealing the first packaging aluminum foil and the second packaging aluminum foil; a third feeding mechanism 30 and a fourth feeding mechanism 40 that are located within the working range of the second conveying mechanism 2 and supply the first packaging aluminum foil; a heat sealing support platform 50 that receives materials from the second conveying mechanism 2; a feeding conveyor line 60 that receives materials from the second conveying mechanism 2 and outputs unloaded materials; and a weighing and inspection mechanism 70 located below the feeding conveyor line 60 that weighs and inspects the packaged wet dressing product.

[0055] During operation, the wet dressing products are stacked in a box, which is placed on the first feeding mechanism 3 for feeding. The first conveying mechanism 1 takes a wet dressing product from the first feeding mechanism 3 and places it on the first receiving and transferring mechanism 6, and takes a PET film from the second feeding mechanism 4 and places it on the surface of the wet dressing product in the first receiving and transferring mechanism 6. The first receiving and transferring mechanism 6 moves the wet dressing product along the X direction from the first receiving position 80 to below the moisture content control mechanism 5, where the moisture content control mechanism 5 squeezes the wet dressing product to a set position. The thickness is fixed; the first receiving and transferring mechanism 6 carries the dehydrated wet dressing product back to the first receiving position 80, the first conveying mechanism 1 removes and discards the PET film from the wet dressing product, and takes out the wet dressing product and transfers it to the second receiving and transferring mechanism 8; the second receiving and transferring mechanism 8 moves the wet dressing product along the X direction from the second receiving position 90 to below the die-cutting mechanism 7, where the die-cutting mechanism 7 cuts a large-sized wet dressing product into multiple small-sized wet dressing pieces; the second receiving and transferring mechanism 8 carries the cut wet dressing products back to the second receiving position 90. The first transport mechanism 1 removes the wet dressing product, transports it to the third receiving position 110, and places it on the third receiving and transfer mechanism 9. The first visual inspection mechanism 10 inspects the size of the wet dressing product and whether there are any foreign objects. If the inspection is OK, the third receiving and transfer mechanism 9 carries the wet dressing product from the third receiving position 110 and moves it along the Y direction to the wet dressing piece feeding position. The second transport mechanism 2 picks up the first packaged aluminum foil from the third feeding mechanism 30 and places it on the heat-sealing support platform 50. It then picks up the wet dressing piece from the third receiving and transfer mechanism 9 and places it on the first packaged aluminum foil. The second packaged aluminum foil is then picked up from the fourth feeding mechanism 40 and placed on the wet dressing product to form a "sandwich" structure. The heat-sealing support platform 50 carries the "sandwich" structure and moves it along the X direction to the bottom of the heat-sealing mechanism 20 or the heat-sealing mechanism 20 moves to the top of the heat-sealing support platform 50. The heat-sealing mechanism 20 heat-presses and seals the first packaged aluminum foil and the second packaged aluminum foil to obtain the wet dressing product. The second handling mechanism 2 takes the wet dressing product off the heat-sealing support platform 50 and places it on the unloading conveyor line 60. The product is then weighed and tested by the weighing and testing mechanism 70.

[0056] The first handling mechanism 1 includes a first multi-axis robot 11, a first mounting bracket 12 disposed at the moving end of the first multi-axis robot 11, a first adsorption module 13, a second adsorption module 14 and a third adsorption module 15 disposed at different positions on the first mounting bracket 12, wherein the first adsorption module 13 is used to adsorb the dewatering diaphragm (PET film), the second adsorption module 14 is used to adsorb the raw material wet dressing product, and the third adsorption module 15 is used to adsorb the dewatered wet dressing product and the wet dressing product cut into multiple small wet dressing pieces.

[0057] The second handling mechanism 2 includes a second multi-axis robot 21, a second mounting bracket 22 disposed at the moving end of the second multi-axis robot 21, and a fourth adsorption module 23, a fifth adsorption module 24, a sixth adsorption module 25, and a seventh adsorption module 26 fixed at different positions on the second mounting bracket 22. The fourth adsorption module 23 is used to adsorb the first packaging aluminum foil, the fifth adsorption module 24 is used to adsorb the cut wet dressing product, the sixth adsorption module 25 is used to adsorb the second packaging aluminum foil, and the seventh adsorption module 26 is used to adsorb the heat-sealed wet dressing product.

[0058] In this embodiment, the first feeding mechanism 3 adopts a dual-station feeding method to achieve continuous feeding, and includes a first driving component 31, a roller conveyor module 32 driven by the first driving component 31 to move horizontally, a stop plate 33 disposed at the end of the roller conveyor module 32, and a thrust assembly 34 disposed at the beginning of the roller conveyor module 32. The thrust assembly 34 includes a first cylinder 341 and a stop bar 342 driven by the first cylinder 341 to move up and down. The operator or automatic equipment places the box containing several wet dressing products on the roller conveyor module 32. The stop plate 33 and the thrust assembly 34 achieve positional limitation in the conveying direction, and the limiting stops on both sides of the roller conveyor module 32 achieve positional limitation perpendicular to the conveying direction, thereby ensuring stable and reliable feeding of the box in a horizontal position.

[0059] The second feeding mechanism 4 is used to supply PET film, the third feeding mechanism 30 is used to supply first packaging aluminum foil, and the fourth feeding mechanism 40 is used to supply second packaging aluminum foil. All three have the same structure and include, sequentially arranged along the conveying direction of the material belt, an unwinding module 41, a pressing module 42, a cutting module 43, and a pulling module 44, as well as a receiving platform 45 for receiving the film material output from the unwinding module 41. One end of the receiving platform 45 extends below the pressing module 42, and a first clearance groove 451 is provided at the position of the cutting module 43. The pressing module 42 includes a second cylinder 421 and a pressing block 422 driven by the second cylinder 421 to move up and down, pressing the tail end of the film material downwards onto the receiving platform 45. The cutting module 43 includes an upper cutter 431 and a lower cutter 432 that cooperate to cut the material, a third cylinder 433 that drives the upper cutter 431 to move up and down, and a fourth cylinder 434 that drives the lower cutter 432 to move up and down. The feeding module 44 includes a second driving member 441, a first support plate 442 that is driven by the second driving member 441 to move along the film output direction, and a pair of clamping assemblies 443 fixed on the first support plate 442 and clamping the film head. The clamping assembly 443 includes an eleventh cylinder 4431 fixed on the first support plate 442 and a gripper 4432 that is driven by the eleventh cylinder 4431 to open and close up and clamp. The receiving platform 45 is provided with a second clearance groove 452 to avoid the movement of the gripper 4432. To ensure the flatness of the output film material, thereby guaranteeing accurate packaging or application, the receiving platform 45 is equipped with several suction holes 453. These holes hold the film material in place after it is pulled out to a set length, ensuring its flatness on the receiving platform 45. The first conveying mechanism 1 and the second conveying mechanism 2 pick up PET film, first packaging aluminum foil, or second packaging aluminum foil from the receiving platform 45.

[0060] In this embodiment, since the raw material wet dressing product contains a lot of moisture and some water will be squeezed out during the dehydration process, in order to prevent the water on the wet dressing product from splashing everywhere, this embodiment sets the first receiving and transferring mechanism 6 and the moisture content control mechanism 5 together in a water tank 51. The water tank 51 is used to collect the water generated during the transfer and dehydration process of the wet dressing product. A drain pipe 52 is provided at the bottom of the water tank 51, and the water is discharged through the drain pipe 52.

[0061] The first receiving and transferring mechanism 6 includes a third driving member 61, a second support plate 62 driven by the third driving member 61 to move in the X direction, and a first carrier tray 63 floating vertically on the second support plate 62. The first carrier tray 63 has a support plate 631 supporting the wet dressing product and first enclosure side plates 632 surrounding the support plate 631. The bottom of the first carrier tray 63 has a drainage hole (not shown in the figure) to drain excess water into the water tank 51. The first carrier tray 63 is driven by the third driving member 61 to reciprocate between the first receiving position 80 and the dewatering position.

[0062] The moisture content control mechanism 5 includes a fourth driving member 53, a dewatering pressure plate 54 driven by the fourth driving member 53 to move up and down, a support base 55 located below the dewatering pressure plate 54 to support the first tray 63, and a second enclosure side plate 56 to prevent water splashing during the dewatering process. The third driving member 61 drives the first tray 63 to move from the first receiving position 80 to below the dewatering pressure plate 54, and supports the Y-direction sides of the first tray 63 by the support base 55. After moving into position, the fourth driving member 53 drives the dewatering pressure plate 54 to move downward, applying a set pressure to the wet dressing product in the first tray 63, squeezing the raw wet dressing product to remove water into a flat shape with a relatively uniform thickness, so that it can be evenly cut later, and ensuring that the thickness uniformity and weight of the cut product meet the requirements, thereby making the moisture content of the product meet the design range requirements.

[0063] A waste film collection tray 57 for collecting used PET film is also provided next to the water tank 51. After the raw wet dressing product is squeezed to remove water, it returns to the first receiving position 80 along with the first carrier tray 63. Then, the first conveying mechanism 1 removes the PET film from the surface of the wet dressing product and places it in the waste film collection tray 57 for unified collection.

[0064] The second receiving and transferring mechanism 8 includes a thirteenth driving member 81 and a second carrier tray 82 that is driven by the thirteenth driving member 81 to move in the X direction. The second carrier tray 82 is driven by the thirteenth driving member 81 to reciprocate between the second receiving position 90 and the slitting position.

[0065] The die-cutting mechanism 7 includes a fifth driving member 71 and a slitting die 72 driven by the fifth driving member 71 to move up and down. In this embodiment, in order to ensure that the thickness of each piece of wet dressing product after slitting is relatively uniform and to prevent local concentration of wet dressing product from causing overall unevenness, which would make it impossible to guarantee that the size of each slitting piece meets the product requirements, the die-cutting mechanism 7 has been optimized in this embodiment. Specifically, the die-cutting mechanism 7 also includes a rolling and smoothing module 73 disposed above the transfer path of the second receiving and transferring mechanism 8, which rolls and smooths the wet dressing product after dehydration. The rolling and smoothing module 73 includes a fifth cylinder 731 and a rolling shaft 732 driven by the fifth cylinder 731 to move up and down and extending along the Y direction. As the second receiving and transferring mechanism 8 carries the wet dressing product from the second receiving position 90 along the X direction to below the slitting die 72, the wet dressing product first moves to below the rolling shaft 732. Then, the fifth cylinder 731 drives the rolling shaft 732 to a low position, and the wet dressing product continues to move. Under the rolling action of the rolling shaft 732, the wet dressing product is rolled and smoothed. After the wet dressing product moves to the slitting station, the fifth driving component 71 drives the slitting die 72 to move downward, cutting a large-sized wet dressing product into multiple small-sized wet dressing pieces. At the same time, the excess scrap material around the large-sized wet dressing product is cut off to ensure that the edges of the slitting wet dressing pieces located at the edge are neat.

[0066] After the cutting is completed, the second receiving and transferring mechanism 8 carries multiple wet-coating pieces back to the second receiving position 90. Then, the third adsorption module 15 on the first conveying mechanism 1 simultaneously adsorbs multiple wet-coating pieces and places them onto the third receiving and transferring mechanism 9. At this time, the second tray 82 of the second receiving and transferring mechanism 8 retains the cut-off scraps. To remove these scraps, the die-cutting mechanism 7 also includes a waste removal module 74 located at the second receiving position 90. The waste removal module 74 includes a sixth cylinder 741, a waste removal scraper 742 driven by the sixth cylinder 741 to move along the Y direction and scrape off the scraps on the second tray 82, and a first waste collection box 743 to receive the waste scraped off by the waste removal scraper 742.

[0067] To improve the versatility of the equipment and ensure its suitability for manufacturing wet dressing products of more sizes, the die-cutting mechanism 7 in this embodiment also includes a sixth driving member 75 and a third support plate 76 driven by the sixth driving member 75 to move along the Y direction. The fifth driving member 71 is disposed on the third support plate 76 and driven by the sixth driving member 75, enabling the slitting die 72 to move in the Y direction. When the size of the wet dressing product can be cut by the slitting die 72 in one go, the sixth driving member 75 does not need to drive the slitting die 72 to move in position. When the size of the wet dressing product requires more than one cut, the sixth driving member 75 can drive the slitting die 72 to move in position to achieve multiple cutting operations, thus meeting the cutting needs of wet dressing products of various sizes.

[0068] The first visual inspection mechanism 10 includes an XY transfer module 101, a first visual camera 102 and a twelfth cylinder 103 located at the active end of the XY transfer module 101, an eighth adsorption module 104 driven by the twelfth cylinder 103 to move up and down, and a second waste collection box 105 located below the transfer range of the XY transfer module 101.

[0069] The third receiving and transferring mechanism 9 includes a seventh drive member 91 and a third carrier tray 92 that is driven by the seventh drive member 91 to move along the Y direction. The third carrier tray 92 is driven by the seventh drive member 91 to reciprocate between the third receiving position 110 and the wet-laying small piece feeding position.

[0070] In another embodiment, the third receiving and transferring mechanism 9 includes a first support platform 93 disposed at the third receiving position 110, a second support platform 94 disposed at the wet patch feeding position, and a transport module 95 for transporting the wet patch from the first support platform 93 to the second support platform 94. The transport module 95 includes an eighth driving member 951, a fourth support plate 952 driven by the eighth driving member 951 to move in the Y direction, a seventh cylinder 953 fixed on the fourth support plate 952, and a ninth adsorption module 954 driven by the seventh cylinder 953 to move up and down.

[0071] In this embodiment, the third feeding mechanism 30 and the fourth feeding mechanism 40 together constitute an aluminum foil feeding unit. This aluminum foil feeding unit and the heat sealing mechanism 20 are respectively arranged on both sides of the wet-laying small piece feeding position in the X direction. In order to ensure that the pattern information on the first packaged aluminum foil supplied by the third feeding mechanism 30 and the second packaged aluminum foil supplied by the fourth feeding mechanism 40 meets the design requirements, this embodiment also provides a second visual inspection mechanism 301 for visual inspection of the first packaged aluminum foil supplied by the third feeding mechanism 30 and the second packaged aluminum foil supplied by the fourth feeding mechanism 40. The third feeding mechanism 30 and the fourth feeding mechanism 40 are arranged opposite each other in the Y direction. The second visual inspection mechanism 301 includes a ninth driving member 3011, an eighth cylinder 3012 driven by the ninth driving member 3011 to move in the Y direction, a fifth support plate 3013 driven by the eighth cylinder 3012 to move in the X direction, and a second visual camera 3014 arranged on the fifth support plate 3013. The transfer range of the ninth drive unit 3011 covers the area where the aluminum foil output by the third feeding mechanism 30 and the fourth feeding mechanism 40 is located.

[0072] In this embodiment, the heat sealing mechanism 20 is moved above the heat sealing support platform 50 to perform the heat sealing operation. Therefore, the heat sealing mechanism 20 includes a tenth driving member 201, a sixth support plate 202 driven by the tenth driving member 201 to move along the X direction, an eleventh driving member 203 fixed on the sixth support plate 202, and a heat sealing mold 204 driven by the eleventh driving member 203 to move up and down. The heat sealing mold 204 is driven by the tenth driving member 201 to reciprocate between a position above the heat sealing support platform 50 and an avoidance position.

[0073] In other embodiments, the heat sealing support platform 50 can be moved below the heat sealing mechanism 20 to perform the heat sealing operation. Therefore, the heat sealing mechanism 20 only includes the eleventh driving member 203 and the heat sealing mold 204 driven by the eleventh driving member 203 to move up and down, while the tenth driving member 201 is used to drive the heat sealing support platform 50 to move in the X direction.

[0074] In this embodiment, the heat sealing mechanism 20 is provided in two sets, which are used to match wet dressing products of different sizes to improve the versatility of the equipment.

[0075] The material feeding conveyor line 60 is equipped with a detection station, and the weighing detection mechanism 70 is located below the detection station, and includes a ninth cylinder 701 and an electronic scale 702 that is moved up and down by the ninth cylinder 701. If the weighing and inspection mechanism 70 detects a defective product, it needs to be removed from the unloading conveyor line 60. In order to realize the defective product rejection function, the structure of the unloading conveyor line 60 has been optimized in this embodiment. Specifically, the unloading conveyor line 60 is equipped with a defective product rejection conveyor line 601 whose conveying range covers the inspection station section. The defective product rejection conveyor line 601 includes a first support shaft 6011 and a second support shaft 6012 arranged in parallel, a conveyor belt 6013 wound between the first support shaft 6011 and the second support shaft 6012, a twelfth driving member 6014 that drives the first support shaft 6011 to rotate, and a tenth cylinder 6015 that drives the second support shaft 6012 to move up and down and thus change the conveying direction of the conveyor belt 6013. A third waste collection box (not shown in the figure) is provided below the end of the conveyor belt 6013 to receive defective products. When the weighing and inspection mechanism 70 detects a defective product, it drives the second support shaft 6012 to move downward through the tenth cylinder 6015, thereby causing the conveyor belt 6013 to transport the product downward along the Y direction and remove the defective product into the third waste collection box.

[0076] The above descriptions are merely some embodiments of the present invention. Those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
