[0048] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0049] like Figure 1-Figure 18 As shown, a method for preparing a shell-type four-side sealed vacuum insulation panel of the present invention comprises the following steps:

[0050] Step 1: prepare the core material and place it on the conveyor line 1. The conveyor line 1 conveys the core material to different stations. Step 2: add desiccant. The conveyor line 1 conveys the core material to the automatic powdering station. The automatic powdering device 2 sprinkles the powdered desiccant on the surface of the core material. Step 3: add the bottom shell. The conveyor line 1 conveys the core material to the upper bottom shell station. The upper bottom shell device 3 clamps the bottom shell to the core material position so that the bottom shell is inverted on the core material. Step 4: flip the bottom shell and the core material. The conveyor line conveys the bottom shell and the core material to the flipping station. The automatic flipping device 4 flips the bottom shell together with the core material 180 degrees so that the opening of the bottom shell faces upward. Step 5: load the material. The conveyor line 1 puts the bottom The shell and core material are conveyed to the loading and unloading station, and the bottom shell clamping mechanism 51 of the loading and unloading device 5 clamps the bottom shell to the tray 522 of the discharge mechanism 52; step six, the barrier film is applied, and the barrier film is placed at the opening position of the bottom shell so that the bottom shell covers the core material; step seven, vacuuming, the tray is pushed into the vacuum equipment 7 for vacuuming, and the barrier film and the bottom shell are heat-sealed together in the vacuum equipment 7; step eight, unloading, the tray 522 is output from the vacuum equipment 7 to the discharge mechanism 52, and the unloading mechanism 53 of the loading and unloading device 5 clamps the shell-type four-side sealed vacuum insulation panel in the tray 522, and the shell-type four-side sealed vacuum insulation panel is finally output from the conveyor line 1.

[0051] When producing shell-type four-side sealed vacuum insulation panels, the core materials are placed one by one on the conveyor line 1, and the core materials are first moved to the powder spreading device station, and the automatic powder spreading device 2 evenly sprinkles the desiccant powder on the core materials, and then the core materials are moved to the upper bottom shell device station, and the upper bottom shell device 3 turns the bottom shell upside down on the core material, and then the bottom shell and the core material are moved to the flipping station, and the automatic flipping device 4 flips the bottom shell and the core material 180 degrees, and then the bottom shell clamping mechanism 51 clamps the bottom shell and the core material to the discharge mechanism 52, and after the barrier film is covered on the bottom shell, the discharge mechanism 52 passes the bottom shell and the core material through the double-layer elevator 6 into the vacuum equipment 7, and the vacuum equipment 7 evacuates them and heat-seals the barrier film and the bottom shell together. After the finished product is made, it is output to the loading and unloading device 5 through the double-layer elevator 6, and finally conveyed to the conveyor line 1 through the loading and unloading device 5, thereby completing the automated production of shell-type four-side sealed vacuum insulation panels.

[0052] In this embodiment, it also includes an upper getter step. After the automatic powder sprinkling device 2 evenly sprinkles the powdered desiccant on the surface of the core material, the conveyor line 1 conveys the core material to the upper getter station, and the upper getter device 3 places the getter on the surface of the core material. By automatically placing the getter on the surface of the core material, after the vacuum insulation panel is manufactured, the getter absorbs the residual gas in the vacuum insulation panel, thereby improving the thermal insulation effect of the vacuum insulation panel.

[0053] Furthermore, in step one, when preparing the core material, the core material of the corresponding size is cut according to the size of the vacuum insulation panel to be manufactured, and then the corners of the core material are chamfered. The core material is preferably a sheet core material, such as a sheet core material such as glass fiber felt. After the core material is cut to a suitable size, the corners of the core material can be chamfered so that the core material and the bottom shell can be better matched.

[0054] In this embodiment, in step 2, when the automatic powder sprinkling device 2 sprinkles desiccant on the core material, the powder receiving mechanism 24 of the automatic powder sprinkling device 2 receives a fixed amount of desiccant, and then places the fixed amount of desiccant in the vibration funnel 256 for sprinkling. By sprinkling a fixed amount of desiccant, the same amount of desiccant is sprinkled when the same specification is used, thereby maintaining a better drying effect while not wasting desiccant easily.

[0055] In this embodiment, in step 2, when the automatic powder sprinkling device 2 sprinkles desiccant on the core material, the powder sprinkling mechanism 25 of the automatic powder sprinkling device 2 moves along the position above the core material, and the powder sprinkling mechanism 25 vibrates at the same time, so as to evenly sprinkle the powdered desiccant on the surface of the core material, thereby preventing the desiccant from piling up and causing an uneven surface of the vacuum insulation panel.

[0056] Furthermore, when placing the bottom shell, the picking mechanism 32 sucks the multiple bottom shells on the discharge assembly 33, and then rotates 90 degrees to turn the multiple bottom shells upside down, so that one bottom shell is turned upside down on a core material, wherein the straight line formed by the multiple bottom shells on the discharge assembly 33 is perpendicular to the conveying direction of the conveyor line. Since the length of the factory site is limited, the length of each workstation needs to be controlled. If the straight line formed by the bottom shells is parallel to the conveying direction of the conveyor line, the upper bottom shell workstation will occupy a longer length. In this regard, the present invention makes the straight line formed by the multiple bottom shells perpendicular to the conveying direction of the conveyor line, and after the picking mechanism 32 sucks the multiple bottom shells, it rotates 90 degrees to turn the multiple bottom shells upside down, so that the length of the upper bottom shell workstation is shorter, which is suitable for the situation where the length of the factory site is limited.

[0057] In a preferred embodiment of the present invention, when the automatic flipping device 4 flips the bottom shell and the core material, the first clamping plate 46 and the second clamping plate 47 of the automatic flipping device 4 clamp the upper and lower surfaces of the bottom shell and the core material, then flip them one hundred and eighty degrees, and finally output them through the flipping conveyor belt. By clamping the bottom shell and the core material, the bottom shell and the core material are more stable during the flipping process.

[0058] Furthermore, in step seven, the double-layer lifter 6 is used to push the tray into the vacuum device 7 for vacuuming; in step eight, the double-layer lifter 6 is used to output the tray from the vacuum device 7 to the discharge mechanism 52.

After the finished product is made, it is output to the loading and unloading device 5 through the double-layer elevator 6, and finally conveyed to the rear conveyor line 12 through the loading and unloading device 5, thereby completing the automated production of shell-type four-side sealed vacuum insulation panels.

The mixer 234 stirs the material evenly, and finally, the material falls onto the material receiving weighing spoon 241. When the material on the material receiving weighing spoon 241 reaches a predetermined weight value, the control system controls the lower hopper 231 to stop discharging the material, and the material receiving weighing spoon 241 rotates to transfer the material to the powder spreading cup 253.

[0067] Preferably, the connecting bracket 242 includes a vertical plate 2421 and a flat plate 2422, one end of the vertical plate 2421 is fixed on the powdering frame 21, and the flat plate 2422 is connected to the other end of the vertical plate 2421. A rotating cylinder 243 is arranged on the flat plate 2422, and the rotating cylinder 243 is connected to the material receiving weighing spoon 241 and drives the material receiving weighing spoon 241 to rotate. By setting the rotating cylinder 243, the rotating cylinder 243 can rotate the material receiving weighing spoon 241 at a certain angle, so as to transfer the material in the material receiving weighing spoon 241 to the powdering cup 253.

[0068] Furthermore, the powder receiving mechanism 24 is mounted in the middle of the powder sprinkling frame 21; the powder sprinkling mechanism 25 includes a first powder sprinkling mechanism 25a and a second powder sprinkling mechanism 25b, the first powder sprinkling mechanism 25a is located on one side of the powder receiving mechanism 24, and the second powder sprinkling mechanism 25b is located on the other side of the powder receiving mechanism 24. By providing the first powder sprinkling mechanism 25a and the second powder sprinkling mechanism 25b, the first powder sprinkling mechanism 25a sprinkles powder on the core material located on one side of the connecting bracket 242, and the second powder sprinkling mechanism 25b sprinkles powder on the core material located on the other side of the connecting bracket 242. When the first powdering mechanism 25a is sprinkling powder on the core material located on one side of the connecting bracket 242, the second powdering mechanism 25b cooperates with the material receiving weighing spoon 241 to receive the material. When the second powdering mechanism 25b is sprinkling powder on the core material located on the other side of the connecting bracket 242, the first powdering mechanism 25a cooperates with the material receiving weighing spoon 241 to receive the material. In this way, the first powdering mechanism 25a and the second powdering mechanism 25b are alternately cooperated with the material receiving weighing spoon 241 to improve the overall powdering efficiency.

[0069] Preferably, a linear rack 2511 is provided on the powdering mounting plate 251, and a driving motor 2521 is provided on the powdering movable seat 252, and the driving motor 2521 is connected to a driving wheel, and the driving wheel is meshed with the linear rack 2511. When the powdering movable seat 252 needs to move, the driving motor 2521 drives the driving wheel to rotate, and since the driving wheel is meshed with the linear rack 2511, the driving wheel rotates to realize the movement of the powdering movable seat 252. Among them, a slide rail 323 is provided on the powdering mounting plate 251, and a slider 324 sliding along the slide rail 323 is provided on the powdering movable seat 252.

For example, the first powder sprinkling mechanism 25a can be provided with three powder sprinkling cups 253, and the second powder sprinkling mechanism 25b can also be provided with three powder sprinkling cups 253. In the initial state, the baffle 2542 blocks the lower discharge port, and the material receiving weighing spoon 241 transfers the material from the upper feed port 2531 to the powder sprinkling cup 253. When it is necessary to sprinkle the material on the core material, the baffle 2542 leaves the lower discharge port under the action of the driving cylinder 2541, thereby achieving the sprinkling of the material on the core material.

[0071] In this embodiment, a pneumatic vibrator is provided at the bottom of the vibration plate 255, and a filter screen is provided at the bottom of the vibration funnel 256.

[0072] In a preferred embodiment of the present invention, Figures 5 to 9 As shown, the upper bottom shell device 3 includes a material picking rack 31, a material picking mechanism 32 and a material discharge assembly 33; the material picking mechanism 32 can be movably arranged on the material picking rack 31 along the X-axis, Y-axis and Z-axis directions, and the material picking mechanism 32 can be rotatably arranged on the material picking rack 31; the material discharge assembly 33 is arranged on one side of the material picking rack 31, and the material discharge assembly 33 includes a guide rail 331, a material discharge table 332 and a material discharge plate 333, and the material discharge table 332 includes a first material discharge table 3321 and a second material discharge table 3322, and the first material discharge table 3321 and the second material discharge table 3322 are arranged side by side. The first unloading table 3321 is slidably set on the guide rail 331 along the X-axis direction, and the second unloading table 3322 is slidably set on the guide rail 331 along the X-axis direction. The unloading plate 333 includes a first unloading plate 3331 and a second unloading plate 3332. The first unloading plate 3331 is set on the first unloading table 3321, and the first unloading plate 3331 can be moved to the bottom of the material picking mechanism 32. The second unloading plate 3332 is set on the second unloading table 3322, and the second unloading plate 3332 can be moved to the bottom of the material picking mechanism 32.

[0073] By setting up the unloading table 332, when in use, after the bottom shell on the unloading plate 333 is sucked, the unloading table 332 moves in the opposite direction of the X-axis, so that the unloading table 332 is away from the material picking station, so as to facilitate stacking multiple bottom shells on the unloading plate 333, and then move the unloading table 332 in the positive direction of the X-axis, so that the unloading table 332 moves to the material picking station, so that the material picking mechanism 32 can pick up the bottom shell and complete the loading of the bottom shell. By setting the first unloading platform 3321 and the second unloading platform 3322, when the bottom shell on the first unloading platform 3321 is sucked up, the material picking mechanism 32 picks up the bottom shell of the second unloading platform 3322, and replenishes the bottom shell of the first unloading platform 3321 at the same time, and when the bottom shell on the second unloading platform 3322 is sucked up, the material picking mechanism 32 picks up the bottom shell of the first unloading platform 3321, and replenishes the bottom shell of the second unloading platform 3322 at the same time, so that the material picking mechanism 32 can continuously pick up the bottom shell, and the material picking efficiency is high. When laying out the upper bottom shell device 3, in the case of some small sites, the reserved position of the upper bottom shell device 3 is narrow. Therefore, the present application sets a first discharge plate 3331 and a second discharge plate 3332, and the sum of the width of the first discharge plate 3331 and the width of the second discharge plate 3332 is smaller than the length of the first discharge plate 3331. The first discharge plate 3331 and the second discharge plate 3332 are both provided with a row of bottom shells along the X-axis direction. For example, a row of bottom shells includes three groups of bottom shells, and each group of bottom shells is stacked with one hundred bottom shells. After the picking mechanism 32 absorbs multiple bottom shells at one time, the picking mechanism 32 is rotated ninety degrees to realize that each bottom shell is inverted on each core material on the conveyor line 1.

[0074] Optionally, the material picking rack 31 includes a column, a first crossbeam, a second crossbeam, a mounting plate 311 and a vertical mounting seat 312, wherein the first crossbeam is fixed on the column, the second crossbeam is movably arranged on the first crossbeam along the X-axis direction, the mounting plate 311 is movably arranged on the second crossbeam along the Y-axis direction, and the vertical mounting seat 312 is movably arranged on the mounting plate 311 along the Z-axis direction. When the material picking mechanism 32 needs to move, the second crossbeam moves to realize the movement of the material picking mechanism 32 along the X-axis direction, the mounting plate 311 moves to realize the movement of the material picking mechanism 32 along the Y-axis direction, and the vertical mounting seat 312 moves to realize the movement of the material picking mechanism 32 along the Z-axis direction, thereby realizing that the material picking mechanism 32 is movably arranged on the material picking rack 31 along the X-axis, Y-axis and Z-axis directions, so as to facilitate the absorption of the bottom shells at different positions on the first discharge plate 3331 and the second discharge plate 3332.

[0075] In this embodiment, a rotating mechanism 313 is provided on the vertical mounting seat 312, and the rotating mechanism 313 is connected to the material picking mechanism 32 and drives the material picking mechanism 32 to rotate. By providing the rotating mechanism 313, after the material picking mechanism 32 sucks the bottom shell, the rotating mechanism 313 drives the material picking mechanism 32 to rotate ninety degrees, so that the material picking mechanism 32 can buckle the bottom shell on the core material of the conveyor line 1. The rotating mechanism 313 is a rotating motor.

[0076] Specifically, the material taking mechanism 32 includes a rotating plate 321 and a suction cup 322, wherein the rotating plate 321 is connected to the rotating mechanism 313 and driven to rotate by the rotating mechanism 313, and the suction cup 322 is arranged on the rotating plate 321. When sucking the bottom shell, the suction cup 322 leans against the bottom shell, and the suction cup 322 generates negative pressure to suck the bottom shell.

[0077] Further, the material taking mechanism 32 also includes a slide rail 323, a slider 324, a suction cup mounting seat 325, a locking member 326 and a suction cup driving cylinder 327. The slide rail 323 is arranged at the bottom of the rotating plate 321, the slider 324 can be slidably arranged on the slide rail 323, the suction cup mounting seat 325 is arranged on the slider 324, the locking member 326 can be rotatably arranged on the suction cup mounting seat 325, the end of the locking member 326 can be pressed against the rotating plate 321, and the suction cup driving cylinder 327 is arranged on the suction cup mounting seat 325. The suction cup driving cylinder 327 is connected to the suction cup 322 and drives it to rise and fall. The length and width of the bottom shell of different specifications are different. When sucking the bottom shell, the specific position of the suction cup 322 can be appropriately adjusted according to the width and length of the bottom shell so that the suction cup 322 can suck the bottom shell tightly. After the suction cup 322 is adjusted to a suitable position, the locking member 326 is operated to fix the suction cup 322 to prevent the suction cup 322 from displacement.

[0078] Among them, multiple groups of suction cups 322 are arranged on the rotating plate 321, each group of suction cups 322 includes four suction cups 322, and each suction cup 322 is connected to the driving cylinder 2541 through a buffer spring. For example, three groups of suction cups 322 are arranged on a rotating plate 321, and each suction cup 322 clamps a bottom shell, thereby achieving one-time clamping of three bottom shells.

[0079] The material taking mechanism 32 further comprises a top separation assembly 328, which comprises a top separation seat 3281 and a top separation rod 3282. The top separation seat 3281 is arranged at the bottom of the rotating plate 321, and the top separation rod 3282 is arranged on the top separation seat 3281 to separate the stacked bottom shells. When the suction cup 322 does not suck the bottom shell, the lower end of the top separation rod 3282 is higher than the suction cup 322.

[0080] When sucking the bottom shell, since multiple bottom shells are stacked one by one, when sucking the bottom shell on the surface, there is a phenomenon that the next bottom shell will be lifted up. In order to solve this problem, the present application sets a top subassembly 328, and the top subassembly 328 is located between four suction cups 322 in a suction cup 322 group. When sucking the outermost bottom shell, the suction cup driving cylinder 327 drives the four suction cups 322 to descend, so that the suction cups 322 first abut against the bottom shell, and then the suction cups 322 continue to descend, so that the end of the top sub-rod 3282 is against the middle of the bottom shell, and then the suction cup driving cylinder 327 drives the suction cups 322 to rise. Since the middle part of the bottom shell is supported by the top sub-rod 3282, the upper bottom shell is easily separated from the lower bottom shell, and finally the suction cups 322 continue to rise, so that the top sub-rod 3282 is separated from the middle part of the bottom shell, so that only the outermost bottom shell is sucked.

[0081] In this embodiment, a positioning assembly 3323 is provided on the material discharge plate 333. Specifically, the positioning assembly 3323 includes a static positioning mounting rod 33231, a first positioning block 33232, a dynamic positioning mounting rod 33233 and a second positioning block 33234. The static positioning mounting rod 33231 is fixed on the material discharge plate 333. The first positioning block 33232 is movably provided on the static positioning mounting rod 33231. The dynamic positioning mounting rod 33233 is movably provided on the material discharge plate 333. The dynamic positioning mounting rod 33233 is parallel to the static positioning mounting rod 33231. The second positioning block 33234 is movably provided on the dynamic positioning mounting rod 33233. By providing the positioning assembly 3323, the bottom shells of different specifications can be limited to prevent the displacement of the bottom shell of the lower layer when the surface bottom shell is sucked. During specific positioning, the dynamic positioning mounting rod 33233 is moved to realize that the second positioning block 33234 is against one side of the bottom shell, while the static positioning mounting rod 33231 is against the other side of the bottom shell. At the same time, since the first positioning block 33232 is movably set on the static positioning mounting rod 33231, and the second positioning block 33234 is movably set on the dynamic positioning mounting rod 33233, in a group of bottom shells, two of the first positioning block 33232 and two of the second positioning block 33234 are set, so that the four positioning blocks are against the four corners of the bottom shell to limit the bottom shell.

[0082] Further, a positioning rail 33235 is provided on the discharge plate 333, a positioning slider 33236 can be slidably provided on the positioning rail 33235, the positioning slider 33236 is connected to the dynamic positioning mounting rod 33233, and a tightening member 33237 is provided on the positioning slider 33236 to tighten the positioning slider 33236 against the positioning rail 33235. By providing the positioning rail 33235 and the positioning slider 33236, it is convenient to move the dynamic positioning mounting rod 33233, so that the second positioning block 33234 abuts against the side of the bottom shell, and after the dynamic positioning mounting rod 33233 moves to a suitable position, the tightening member 33237 is operated to make the tightening member 33237 press against the side of the positioning rail 33235, and the positioning slider 33236 is locked.

[0083] In order to further ensure that the suction cup 322 only sucks one bottom shell at a time, it also includes a first brush assembly 34 and a second brush assembly 35. The first brush assembly 34 includes a first brush seat 341 and a brush cylinder 342. The first brush seat 341 is set on the discharge plate 333 or the static positioning mounting rod 33231. The brush cylinder 342 can be rotatably set on the first brush seat 341. The brush cylinder 342 is located directly above one side of the bottom shell. The second brush assembly 35 includes a second brush seat 351 and a brush block 352. The second brush seat 351 is set on the dynamic positioning mounting rod 33233. The brush block 352 is set on the second brush seat 351. The brush block 352 is located directly above the other side of the bottom shell. Among them, the first brush seat 341 can be provided with a motor to drive the brush cylinder 342 to rotate.

[0084] When the suction cup 322 sucks the surface bottom shell, if the next bottom shell is lifted up, the two sides of the surface bottom shell and the next bottom shell pass through the brush block 352 and the brush cylinder 342 respectively. The brush block 352 and the brush cylinder 342 have multiple brushes, so that the next bottom shell is separated from the surface bottom shell.

[0085] In this embodiment, running wheels 615 that move along the guide rails 331 are provided at the bottom of the unloading platform 332. By providing the running wheels 615, the unloading platform 332 can move more stably.

The walking base 33242 can be fixed on the ground, and the guide rail 331 can also be fixed on the ground. When the unloading platform 332 needs to move, the walking motor 33241 drives the gear to rotate. Since the rack 33243 is meshed with the gear, the walking wheel 615 of the unloading platform 332 is driven to move stably along the guide rail 331.
