The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it should not be understood as a limitation on the scope of protection of the present invention.

[0046] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0047] In the description of the present invention, "several" means one or more, "many" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0048] In the description of the present invention, unless otherwise clearly defined, words such as setting and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above words in the present invention based on the specific content of the technical solution.

[0049] In the production of ceramic components such as solid-state batteries and ceramic substrates, the surface roughness of the final product is required to be high enough. To achieve this, a roughening agent is applied to both sides of the ceramic green sheets. The green sheets and the roughening agent are then stacked and bagged in a certain order, then vacuum-packed. After isostatic pressing, the roughening agent is removed from the bag to obtain ceramic sheets that meet the roughness requirements, allowing for subsequent production steps. Currently, packaging is primarily done manually, but due to the large amount of packaging materials and the need for neat organization during packaging, manual packaging is inefficient and prone to leaks and overpacking.

[0050] See also Figure 1 and Figure 2 Some embodiments of the present invention provide an automatic vacuum packaging machine, which includes a film belt assembly 100, a silo assembly 200, a cutting assembly 700, a conveying assembly, a pressing assembly 500, and a vacuum pressing assembly 600.

[0051] It is understandable that the materials in this embodiment are mainly ceramic green sheets and roughening media. Of course, they can also be other materials such as parts, tiles, etc.

[0052] The film tape assembly 100 is used for packaging materials. The film tape assembly 100 includes an upper film tape assembly 110 and a lower film tape assembly 120. The upper film tape assembly 110 includes an upper film roll 111, an upper film conveying device and an upper film driving component. The upper film roll 111 is pulled open to form an upper film tape. The lower film tape assembly 120 includes a lower film roll 121, a lower film conveying device, a lower film driving component and a pallet assembly 130. The lower film roll 121 is pulled open to form a lower film tape.

[0053] The upper film drive component is connected to the upper film roll 111, and the upper film drive component is also connected to the upper film conveying device to provide tension during the upper film belt conveying process. The upper film belt is flattened on the upper part of the lower film belt after conveying. The lower film belt assembly 120 is horizontally arranged below the upper film belt assembly 110, and the support plate assembly 130 is horizontally arranged on one side of the lower film roll 121 (for example, see Figure 5 and Figure 6 , the pallet assembly 130 is horizontally arranged on the upper right side of the lower film roll 121), the lower film driving component is connected to the lower film roll 121, and the lower film driving component is also connected to the lower film conveying device to provide tension during the conveying process of the lower film belt. The lower film belt is flattened on the pallet assembly 130 after conveying.

[0054] In some embodiments, the upper film driving component and the lower film driving component are respectively the first torque motor 112 and the second torque motor 122. Of course, the upper film driving component or the lower film driving component can also be other driving components such as a DC speed regulating motor and an AC variable frequency motor.

[0055] It can be understood that the upper film conveying device is three first transition rollers 113, and the lower film conveying device is one second transition roller 123. Of course, the upper film conveying device or the lower film conveying device can also be other conveying devices such as rollers and conveyor belts.

[0056] See also Figure 3 and Figure 4 , the upper film belt assembly 110 also includes a first air-expanding shaft 114, a first bearing 115 and a first bearing seat 116. It can be understood that the first air-expanding shaft 114 is a special winding and unwinding shaft. After high-pressure inflation, the surface portion can expand, and after deflation, the surface portion quickly retracts. The upper film roll 111 is mounted on the first air-expanding shaft 114. The first air-expanding shaft 114 is connected to the first bearing seat 116 through the first bearing 115. The first torque motor 112 is connected to the first air-expanding shaft 114 through the first bearing 115. The first torque motor 112 is also connected to the three first transition rollers 113 to provide tension during the transmission of the upper film roll 111, wherein two first transition rollers 113 are spaced apart and arranged on one side of the upper film roll 111 (for example, see Figure 3 or Figure 4, two first transition rollers 113 are arranged at intervals on the left side of the upper film roll), and another first transition roller 113 is arranged directly below the first transition roller 113 away from the upper film roll 111. The upper film roll 111 is laid flat on the lower film belt after passing through the three first transition rollers 113.

[0057] See also Figure 5 and Figure 6 The lower film belt assembly 120 also includes a second air expansion shaft 124, a second bearing 125 and a second bearing seat 126. It can be understood that the lower film roll 121 is mounted on the second air expansion shaft 124, and the second air expansion shaft 124 is connected to the second bearing seat 126 through the second bearing 125. The second torque motor 122 is connected to the second air expansion shaft 124 through the second bearing 125. The second torque motor 122 is also connected to a second transition roller 123 to provide tension for the upper film roll 111 during the transmission process. The second transition roller 123 is arranged on the side of the pallet assembly 130 close to the lower film roll 121, so that the lower film belt can be flattened on the pallet assembly 130 after transmission.

[0058] The silo assembly 200 is used to load materials. It includes a loading bin 210, a lifting device, and a third drive component. The loading bin 210 includes a movable base plate 211. The lifting device is connected to the base plate 211, and the third drive component is connected to the lifting device to drive the base plate 211 up and down to facilitate loading and feeding. The silo assembly 200 is divided into a feed bin assembly and a discharge bin assembly. The feed bin assembly is located behind the vacuum pressing assembly along the material conveying direction and is used to transport materials. The discharge bin assembly is located in front of the vacuum pressing assembly along the material conveying direction and is used to transport vacuum-packaged finished products.

[0059] In some of these embodiments, see Figure 7 The lifting device includes a limiting angle block 220, a gear 230, and a rack 240. The third driving component is a first stepper motor 250. The limiting angle blocks 220 are used to position the loading bin 210 on all sides. The base plate 211 is connected to the gear 230 via the rack 240. The first stepper motor 250 is connected to the gear 230 to move the rack 240 up and down, driving the base plate 211 up and down, facilitating loading and feeding of materials to the base plate 211.

[0060] In some embodiments, the automatic vacuum packaging machine includes three sets of feed bin assemblies, divided into two groups, respectively disposed on either side of the pressure delivery assembly 500, away from the support plate assembly 130. The first group includes two sets of feed bin assemblies for loading ceramic green sheets, and the second group includes one set of feed bin assemblies for loading the third roughening medium. The feed bin assemblies are connected to a first pressure sensor, which is connected to a first automatic alarm. The loading bin 210 is loaded with a certain number of ceramic green sheets or roughening medium. When all the green sheets or roughening medium are removed (the pressure on the bottom plate 211 is 0), an automatic alarm is triggered, and new ceramic green sheets or third roughening medium are manually added.

[0061] In some other embodiments, the automatic vacuum packaging machine further includes a paper feeding assembly 800, see Figure 8 The paper feeding assembly 800 includes a paper roll 810, a sixth drive component, a table 870 and a roller assembly 880. The sixth drive component is connected to the paper roll 810, and the sixth drive component is also connected to the roller assembly 880 to provide tension during the transmission of the paper roll 810. The paper roll 810 is flattened on the table 870 after transmission. The material can be placed on the table 870 and then transported to the work station for stacking by the conveying assembly.

[0062] In some embodiments, see Figure 2 The automatic vacuum packaging machine includes four sets of paper feed assemblies 800, divided into two groups and arranged on either side of the pressure feed assembly 500, away from the support assembly 130. The first set of paper feed assemblies includes two sets of paper feed assemblies 800, which are used to transport the first roughened medium and are arranged on either side of the first feed hopper assembly 200. The second set of paper feed assemblies includes two sets of paper feed assemblies 800, which are used to transport the second roughened medium and are arranged on either side of the second feed hopper assembly 200. The distance between the paper feed assemblies 800 and the hopper assembly 200 is equal to the distance between the first suction cup assemblies 310, and the number of first suction cup assemblies 310 on either side is also the same, facilitating suction cup material removal. The paper feeding assembly 800 includes a paper roll 810, a third air expansion shaft 820, a fourth bearing 830, a fourth bearing seat 840, a second stepper motor 850, a third synchronous pulley 860, a platen 870 and a roller assembly 880, wherein the roller assembly 880 includes a driving roller 881, a follower roller 882 and a pressure roller 883. The paper roll 810 is mounted on the third air expansion shaft 820, and the third air expansion shaft 820 is mounted on the fourth bearing seat 840 through the fourth bearing 830. The follower roller 882 is arranged above the paper roll 810 and below the support plate assembly 130, the pressure roller 883 is arranged above the support plate assembly 130, the driving roller 881 is arranged above the pressure roller 883, and the platen 870 is arranged on one side of the pressure roller 883 (for example, see Figure 8, platen 870 is located to the right of pressure roller 883). The paper is pulled around follower roller 882 to the active roller 881 and pressure roller 883. Pressure roller 883 can adjust the gap with active roller 881 up and down to compact the paper for transport. A second stepper motor 850 is connected to active roller 881 via a third synchronous pulley 860, driving active roller 881 to transport the paper. After transport, the paper is placed on platen 870. Materials can be placed on platen 870 and then transported to a workstation by the transport assembly for stacking.

[0063] In some embodiments, the automatic vacuum packaging machine includes five cutting assemblies 700. One cutting assembly 700 is positioned in front of the vacuum pressing assembly 600 along the material conveying direction and is used to cut the sealed vacuum-packaged product. Four other cutting assemblies 700 are positioned at the front of the paper feeding assembly 800 and are used to cut the paper roll 810. The cutting assembly 700 includes a cutter 710, a cutter holder 730, and a seventh drive component. The cutter 710 is positioned on the cutter holder 730, and the seventh drive component is connected to the cutter 710 to drive the cutter 710 to cut.

[0064] In some of these embodiments, see Figure 9 and Figure 10 The cutting assembly 700 includes a cutter 710, a second pressure plate 720, a cutter holder 730, a guide pressure block 740, and a buffer device. The cutter 710 is mounted on the cutter holder 730 using the second pressure plate 720 and passes through the guide pressure block 740 for limited cutting. Buffer devices are provided on both sides of the cutter holder 730. The buffer devices include a guide shaft 750, a third linear bearing 760, and a spring 770. The guide shaft 750 is connected to the cutter holder 730 via the third linear bearing 760. The spring 770 is mounted on the guide shaft 750, and the upper end of the spring 770 is connected to the third linear bearing 760. When the vacuum-packed product reaches its sealed position, it is driven downward by the seventh cylinder 780 for cutting.

[0065] The conveying assembly is used to convey materials. The conveying assembly includes at least one picking device, a fourth driving component and a fifth driving component. The fourth driving component and the fifth driving component are both connected to the picking device. The fourth driving component can drive the picking device to move up and down to pick up and place materials. The fifth driving component can drive the picking device to move in the horizontal direction to transport materials.

[0066] In some embodiments, the object-retrieving device is a suction cup assembly, each of which is symmetrically provided with two first guide posts 311 and two first guide sleeves 312 on both sides to provide upper and lower buffering during suction, and vacuum is introduced by the first guide posts 311. It is understood that the object-retrieving device may also be a robot arm, a clamp, or other object-retrieving device.

[0067] It is understandable that the fourth driving component is the first servo motor 360 and the fifth driving component is the first cylinder 350. Of course, the fourth driving component can also be a servo motor or other driving components and the fifth driving component can also be a cylinder or other driving components.

[0068] The conveying assembly is divided into a feed conveying assembly 300 and a discharge conveying assembly 400. The feed conveying assembly 300 is arranged behind the vacuum pressing assembly 600 along the material conveying direction, and is used to convey the material to the work station. The discharge conveying assembly 400 is arranged in front of the vacuum pressing assembly 600 along the material conveying direction, and is used to convey the vacuum-packed finished product to the discharge bin.

The conveying plate 320 is parallel to the pallet assembly 130 and is connected to the two first linear guide rails 340. The seven sets of first suction cup assemblies 310 are divided into two groups and fixed on the conveying plate 320. The first group of first suction cup assemblies consists of three sets of first suction cup assemblies 310 arranged on one side of the conveying plate 320 (for example, see Figure 11 The first set of first suction cup assemblies is located on the inner side of the conveying plate 320), and the second set of first suction cup assemblies is four sets of first suction cup assemblies 310 arranged on the other side of the conveying plate 320 (for example, see Figure 11 The first set of first suction cup assemblies is located outside the conveying plate 320. The first rotating shaft 362 is fixed to the third bearing seat 363, which is mounted on one of the first linear guide rails 340. The first synchronous pulley 361 is mounted on the outside of the other first linear guide rail 340. The conveying plate 320 is connected to the first rotating shaft 362. The first servo motor 360 drives the first rotating shaft 362 via the first synchronous pulley 361, thereby driving the conveying plate 320 to move the seven sets of first suction cup assemblies 310 back and forth along the two first linear guide rails 340 to transport materials. The two groups of first suction cup assemblies 310 are respectively connected to the two fixed plates 330, and the two first cylinders 350 are respectively connected to the two fixed plates 330 through the first universal joints 351. A second guide device 370 is provided on both sides of each fixed plate 330 to guide and drive the first suction cup assembly 310 to work up and down to pick up and place materials. The second guide device 370 includes a second guide column 371 and a second guide sleeve 372.

[0070] The pressure-feeding assembly 500 is used to pressure-feed materials. The pressure-feeding assembly 500 includes at least one pressure component and a conveying device. The pressure component is located above the support plate assembly 130 and is used to compress the materials. The conveying device is used to convey the materials forward along the support plate assembly 130.

[0071] In some embodiments, the conveying device may be a guide rail, or other conveying devices such as a roller or a conveyor belt.

[0072] See also Figure 14 and Figure 15 The pressure-feeding assembly 500 also includes a first connecting plate 510, a second connecting plate 520 and a third driving component, and the conveying device includes two second guide rails 530 and two third guide rails 540.

The two ends of the second connecting plate 520 are respectively connected to the two third guide rails 540 to enable the second connecting plate 520 to move left and right. The third driving component is connected to the first connecting plate 510 and the second connecting plate 520, thereby driving the first connecting plate 510 and the second connecting plate 520 to perform synchronous stepping movements. The pressure-applying component can be connected to the rotating cylinder 551 or the cylinder to drive the pressure-applying component to pressurize the material. The pressure-applying component is located above the pallet assembly 130.

[0073] In other embodiments, the pressure conveying assembly 500 further includes a second synchronous pulley assembly 570, which includes a second synchronous pulley 571, two circular pulleys 572, and multiple circular belts 573.

[0074] In some embodiments, the third driving component is the second servo motor 580. Of course, the third driving component can also be other driving components such as a cylinder and a stepping motor.

[0075] It is understandable that one or more pressure components are provided on the first connecting plate 510 or the second connecting plate 520. In some embodiments, the pressure component is the first pressure plate 560. Of course, the pressure component can also be other pressure components such as the pressure rod 550.

[0076] See also Figure 15Eight pressing rods 550 are symmetrically arranged on the first connecting plate 510 and the second connecting plate 520 behind the vacuum pressing assembly 600 along the material conveying direction. The eight pressing rods 550 are connected to the rotating cylinder 551, which drives the pressing rods 550 to press the placed materials to prevent them from deviation during the conveying process. Figure 14 A first pressing plate 560 is arranged on the first connecting plate 510 in front of the vacuum pressing assembly 600 along the material conveying direction, and the fourth cylinder 561 is connected to the first pressing plate 560 to drive the first pressing plate 560 to press the sealed vacuum-packed product.

[0077] The vacuum pressing assembly 600 is arranged through the pallet assembly 130. The upper end of the vacuum pressing assembly 600 is provided with an outer cover 630. The outer cover 630 is located above the pallet assembly 130. Except for the bottom opening, the other surfaces of the outer cover 630 are sealed structures. The inner cavity of the outer cover 630 is provided with a sealing component. The vacuum pressing assembly 600 also includes a first driving component, a second driving component and a vacuum pumping device. The vacuum pumping device is connected to the outer cover 630. The first driving component is connected to the outer cover 630 to drive the outer cover 630 to move up and down. When the outer cover 630 moves downward and is pressed against the pallet assembly 130 so that the film strip forms a sealed space to wrap the material, the vacuum pumping device vacuums the sealed space. The second driving component is connected to the sealing component to drive the sealing component to move up and down. The sealing component moves downward to package the film strip that has been vacuumed to form a vacuum-packaged finished product.

[0078] See also Figure 16The vacuum pressing assembly 600 also includes an upper connecting plate 610 and a lower connecting plate 620.

[0079] In some of the embodiments, the sealing component is a four-sided sealing block 640 with a nickel-chromium alloy sheet 641. The sealing adopts heat sealing, that is, the current after the nickel-chromium alloy sheet 641 is energized generates a high temperature at the moment of discharge. It can be understood that the sealing component can also be a circular sealing block with a nickel-chromium alloy sheet 641, a pulse sealing machine, a rotary sealing machine or other sealing components.

[0080] The outer cover 630 is a sealing cover with a sealing strip, and can also be a polypropylene sealing cover, a fiberglass sealed cover or other sealing structures.

[0081] See also Figure 17 The discharge conveying assembly 400 is used to convey the vacuum-packed finished products to the discharge bin assembly. The discharge conveying assembly 400 is arranged in front of the cutting assembly 700 for film cutting along the material conveying direction. The discharge conveying assembly 400 includes a second cylinder 410, a third cylinder 420 and a second suction cup assembly 430.

The third cylinder 420 drives the second suction cup assembly 430 to move horizontally along the material conveying direction to complete transportation.

[0082] The automatic vacuum packaging machine includes two discharge bin assemblies for loading vacuum-packed finished products: one for the working bin and the other for the standby bin. The discharge bin assembly is connected to a second pressure sensor, which in turn is connected to a second automatic alarm. When a certain number of products are reached (when the pressure on the bottom plate 211 reaches a defined value), the machine automatically stops. Then, a pneumatic cylinder activates the standby bin, switching the full loading bin 210 to manual removal of finished products.

[0083] How to use the automatic vacuum packaging machine: The embodiment of the present invention can solve the problem of automatic vacuum packaging of ceramic embryos. When working, the lower film belt is laid flat on the pallet assembly 130 to form a workstation 900, which is divided into the first workstation 910, the second workstation 920, the third workstation 930, the fourth workstation 940, the fifth workstation 950, the sixth workstation 960, the seventh workstation 970, the eighth workstation 980, and the ninth workstation 990 in sequence along the material conveying direction. The first station 910 to the fourth station 940 are used for stacking materials. The fifth station 950 detects whether there are stacked materials through a pressure sensor. The sixth station 960 is located at the vacuum pressing assembly 600 to vacuum-package the stacked materials. The seventh station 970 is the starting position of the first pressing plate 560 in the pressure-feeding assembly 500. The first pressing plate 560 can press the sealed vacuum-packaged finished product. The pressure-feeding assembly 500 presses the vacuum-packaged finished product to the ninth station 990. The cutting assembly 700 cuts the film tape to form a bagged finished product. The discharge conveying assembly 400 conveys the bagged vacuum-packaged finished product to the discharge bin assembly for storage.

[0084] Specifically, the lower membrane strip is first pulled to the eighth station 980. Simultaneously, the upper membrane strip is also pulled to the eighth station 980 to align with the lower membrane strip. After automatic operation begins, each material hopper assembly lifts the material to the appropriate height, and the conveying assembly moves the material back and forth. At the first station 910, the first and second roughening media are stacked. At the second station 920, the ceramic green sheet and the third roughening media are stacked. At the third station 930, the ceramic green sheet and the second roughening media are stacked. Finally, at the fourth station 940, the first roughening media is stacked on the lower membrane strip in the order of the first roughening media, second roughening media, ceramic green sheet, third roughening media, ceramic green sheet, second roughening media, and first roughening media. During this process, the absorption of each material is monitored by a pressure sensor to ensure smooth absorption. The fifth station 950 is a detection station, where a pressure sensor is used to detect whether any material is stacked. At the sixth station 960, the vacuum pressing assembly 600 vacuum-seals the stacked materials on all four sides to form a bagged form. The seventh station 970 is the starting position of the first pressure plate 560 in the pressure-feeding assembly 500. After the actions of each station are completed (each station operates simultaneously), the pressure-feeding assembly 500 transfers the materials to the next station. After the vacuum-packed finished product is pressed by the first pressure plate 560 to the ninth station 990, the cutting assembly 700 cuts the film strip behind it, thus forming a bagged finished product. After the cutting assembly 700 cuts, the discharge conveying assembly 400 conveys the bagged vacuum-packed finished product to the discharge silo assembly 200 for storage. Each station of the equipment operates simultaneously and repeatedly, and finally continuously conveys the bagged vacuum-packed finished product to the discharge silo assembly 200 for stacking. When the discharge silo assembly 200 stores a certain number of products, the discharge silo switches to the spare silo and continues to store them. The full silo is manually removed. If any materials are consumed during the process, the equipment will be paused and manual replenishment will be required.

[0085] In some other embodiments, the automatic vacuum packaging machine further includes a frame assembly 1000, see Figure 18The rack assembly 1000 includes an upper rack 1010, a panel 1020, and a lower rack 1030. The upper rack 1010 is connected to the lower rack 1030 through the panel 1020. The bottom of the lower rack 1030 is symmetrically provided with a plurality of rolling components and supporting components. The rolling components are universal wheels, and the supporting components are support legs. When the rack assembly 1000 needs to be fixed, the support legs are in contact with the ground to support the rack assembly 1000. When the rack assembly 1000 needs to be moved, the rack assembly 1000 can be moved by contacting the ground with the universal wheels, saving time and effort. The interior of the upper rack 1010 is connected and is used to place the above-mentioned film strip assembly, vacuum pressing assembly 600, pressure delivery assembly 500, conveying assembly, silo assembly 200 and cutting assembly 700. The upper frame 1010 is provided with a plurality of openable and closable doors, which can be closed to prevent dust when the automatic vacuum packaging machine is not in use. The lower frame 1030 is provided with a plurality of openable and closable cabinets, which can be used to store materials or work items such as work clothes.
