The bottom shell clamping mechanism 51 clamps the bottom shell of the rear conveyor line 12 together with the core material to the discharge mechanism 52, one end of the discharge mechanism 52 is connected to the double-layer elevator 6, and the discharge mechanism 53 is erected above the discharge mechanism 52; the double-layer elevator 6 includes an upper roller 623 and a lower roller 624, and the upper roller 623 and the lower roller 624 can be raised and lowered to make the upper roller 623 or the lower roller 624 flush with the discharge mechanism 52; the vacuum equipment 7 is connected to the double-layer elevator 6.

[0074] Thus, the present invention relates to a mass production line for shell-type four-side sealed vacuum insulation panels. When producing shell-type four-side sealed vacuum insulation panels, the core materials are placed one by one on the front conveyor line 11, and the core materials are first moved to the automatic powder sprinkling device 2 station, and the automatic powder sprinkling device 2 evenly sprinkles the desiccant powder on the core materials. Then the core materials are moved to the upper bottom shell device 3 station, and the upper bottom shell device 3 turns the bottom shell upside down on the core materials. Then, the bottom shell and the core materials are moved to the flipping device 4 station, and the flipping device 4 flips the bottom shell and the core materials one hundred and eighty Ten degrees, then the bottom shell clamping mechanism 51 clamps the bottom shell and the core material to the discharge mechanism 52, and after covering the barrier film on the bottom shell, the discharge mechanism 52 passes the bottom shell and the core material into the vacuum equipment 7 through the double-layer elevator 6, 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 transported 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.

One end of the elevator 233 is connected to the silo 232, and the lower hopper 231 is connected to the other end of the elevator 233. The mixer 234 is arranged on the powder spreading frame 21, and the mixer 234 is connected to the lower hopper 231 and stirs the material in the lower hopper 231. When in use, the material is loaded into the silo 232, and the material in the silo 232 is transferred to the mixer 234 under the action of the elevator 233. 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.

[0079] 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.

[0080] 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.

[0081] 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. When the powdering movable seat 252 moves in this way, the slider 324 slides along the slide rail 323, so that the movement process of the powdering movable seat 252 is smoother.

[0082] In this embodiment, a plurality of powdering cups 253 are arranged side by side and evenly arranged on the powdering movable seat 252, the upper end of the powdering cup 253 is an upper feed port 2531, and the lower end of the powdering cup 253 is a lower discharge port.

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.

[0083] 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. The pneumatic vibrator drives the vibration plate 255 to vibrate, thereby realizing that the material in the vibration funnel 256 is spread from the filter screen to the core material more evenly.

[0084] In a preferred embodiment of the present invention, Figures 5 to 9As 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.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] Specifically, a walking mechanism 3324 is provided at the bottom of the unloading platform 332 to drive the unloading platform 332 to move. The walking mechanism 3324 includes a walking motor 33241, a gear, a walking base 33242 and a rack 33243. The walking motor 33241 is provided at the bottom of the unloading platform 332.

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.
