[0024] In one embodiment, the second bin mechanism 2 includes a second nut seat 21, a second screw rod 22 installed in the second nut seat 21, and a second motor for driving the second screw rod 22. The second nut seat 21 is connected to the first support plate 24 through a second column 23, and the first support plate 24 stores the packaging sheet. The second column 23 passes through a bottom plate 25 and is connected to the first support plate 24. The bottom plate 25 is provided with a plurality of limit columns 26. The plurality of limit columns 26 are enclosed to form a positioning for the packaging sheet. The limit columns 26 are provided with blowing holes 261. The second bin mechanism 2 is installed on the second transport line 27. The second transport line 27 includes a third cylinder 271 and a first guide rail 272. The driving end of the third cylinder 271 is connected to the second bin mechanism 2, and the second bin mechanism 2 is slidably installed on the first guide rail 272.

[0025] In one embodiment, after the first transplanting robot 3 takes the product from the first silo mechanism 1 , it puts the product on the secondary positioning platform 10 for positioning. The secondary positioning platform 10 has a positioning groove 101 that matches the product.

[0026] In one embodiment, a receiving mechanism 17 is further provided below the loading area 100 of the first silo mechanism 1. The receiving mechanism 17 includes a lifting assembly 171 and a lifting seat 172 driven by the lifting assembly 171. A fourth cylinder 173 is provided on the lifting seat 172. The driving end of the fourth cylinder 173 is connected to the second support plate 174. The second support plate 174 is used to receive the tray 11. After all the products in the tray 11 are taken away, the lifting assembly 171 drives the second support plate 174 to rise to a certain extent, and the fourth cylinder 173 drives the second support plate 174 to rise for the second time. The second support plate 174 receives the empty tray 11, and the first supporting claw 142 of the material taking and transplanting assembly 15 releases the tray 11. The fourth cylinder 173 is reset, and the second support plate 174 descends. The lifting assembly 171 then drives the second support plate 174 to continue to descend.

[0027] In one embodiment, the second heating rod 72 is inserted into a heating block 73 . The heating block 73 has a downwardly convex square body 731 . The heating block 73 is driven downward by the second pressing assembly 71 .

[0028] In one embodiment, the unloading and transplanting mechanism 9 includes a plurality of clamping cylinders 91 located on both sides of the bottom film 512 and the surface film 522. The plurality of clamping cylinders 91 on both sides are slidably mounted on the corresponding second guide rails 92 through mounting seats 97. The mounting seats 97 are also connected to a belt 93. Both ends of the belt 93 are connected to different pulleys 94. Any pulley 94 is connected to a drive shaft 95. The drive shaft 95 is driven to rotate by a third motor 96.

[0029] In one embodiment, the first silo mechanism 1, the second silo mechanism 2, the first transplanting robot, the second transplanting robot, the conveyor belt 5, the transverse sealing mechanism 6, the longitudinal sealing mechanism 7, and the cutting mechanism 8 are all arranged on a frame and covered by a casing installed on the frame. A plurality of exhaust devices are arranged on the top of the casing, and the exhaust devices are connected to the dust collecting device through a pipe.

[0030] When the vacuum packaging device is working, the following steps are included: 1. Manually place the full material tray 11 into the silo 12, and the first motor 134 of the first lifting assembly 13 rotates, driving the first screw rod 135 to rotate. The rotation of the first screw rod 135 causes the first nut 132 to rise, thereby driving the lifting plate 131 to lift and support the material tray 11. At this time, the first supporting claw 142 of the material dividing assembly 14 retreats, and all the material trays 11 drop to the height of the material tray 11 with the first lifting assembly 13. Then the first supporting claw 142 of the material dividing assembly 14 is driven back by the first cylinder 141 to support the second-to-last material plate, and the bottom material tray 11 continues to drop to the material picking and transplanting assembly 15 with the first lifting assembly 13. The second cylinder 151 in the material picking and transplanting assembly 15 drives the second supporting claw 152 to receive the material tray 11, and the first transport line 16 moves the material picking and transplanting assembly 15 to the loading area.

[0031] 2. Manually stack the packaging sheets and place them between the multiple limit columns 26 on the bottom plate 25, that is, on the pallet. The packaging sheets can specifically be silicone sheets, which are used to cover the back shell products of the mobile phone to play a protective role. The packaging sheets of the second silo mechanism 2 cooperate with the second transplanting manipulator. When taking materials, the second motor drives the second screw rod 22 to rotate, thereby driving the second nut seat 21 to rise. The second nut seat 21 drives the pallet to rise through the second column 23, and the pallet drives the packaging sheets to rise. In this way, the second transplanting manipulator only needs to descend to a fixed height each time to accurately take materials.

[0032] 3. The first transplanting robot automatically picks up two products from the material tray 11 that arrives at the loading area to the secondary positioning platform 10, so that the posture of the products is corrected, and then takes them and places them on the bottom film 512 on the conveyor belt 5. The conveyor belt 5 moves a distance, and the bottom film 512 and the products thereon move to the upper material position of the packaging sheet; at the same time, the second transplanting robot picks up two sheets from the second silo mechanism 2 and places them on the products; wherein, the bottom film 512 is pulled from the first unwinding roller 511 to the bottom of the first pressing roller 513 in advance, and the bottom film 512 is sucked by the vacuum adsorption holes 531 on the conveyor belt 5, and moves with the movement of the conveyor belt 5.

[0033] 4. The conveyor belt 5 moves the product and the silicone to a certain distance, and the mask 522 is discharged to cover the product at the same time; wherein, the mask 522 is pulled from the second unwinding roller 521 to the bottom of the second pressing roller 523, covers the product and the bottom film 512, and after transverse heat sealing and longitudinal heat sealing, the mask 522 is attached to the bottom film 512.

[0034] 5. The product and the packaging sheet are moved to the bottom of the transverse sealing mechanism 6 by the unloading and transferring mechanism, pulling the bottom film 512 and the face mask 522. The transverse seal is pressed down to perform heat sealing, that is, the first pressing component 62 drives the heating block 73 to press down, and the heating block 73 realizes heat sealing of the bottom film 512 and the face mask 522 under the heating of the first heating rod 61. Specifically, since most of the conveyor belts 5 in the prior art are not suitable for contact with the heating rod, the clamping cylinder 91 in the unloading and transferring mechanism can clamp the bottom film 512 and the face mask 522, and then the third motor drives the driving shaft, and then drives the pulley. The rotation of the pulley causes the belt 93 to move, and then the clamping cylinder 91 can pull the bottom film 512 and the face mask 522 to move.

[0035] 6. The clamping cylinder 91 in the unloading and transplanting assembly 9 moves the product to the bottom of the longitudinal sealing mechanism 7, and the first second heating rod 72 presses down to heat-seal one side of the bottom film 512 and the face film 522, and the vacuum rod 74 evacuates the space between the bottom film 512 and the face film 522 on the other side. When the vacuum pressure reaches the vacuum value, the second second heating rod 72 presses down to heat-seal, and the longitudinal heat sealing is performed from one side to the other side in sequence to ensure that there is no air between the bottom film 512 and the face film 522.

[0036] 7. The material unloading and transferring mechanism continues to pull the product and transfers the product to the bottom of the cutting mechanism 8. The cutter 81 is pressed down and moves, and the cutter 81 cuts the bottom film 512 and the surface film 522.

[0037] 8. Since the material unloading and transferring mechanism still clamps one side of the bottom film 512 and the surface film 522, the finished product can be moved to the unloading frame by continuing to move the material unloading and transferring mechanism.

[0038] Beneficial effects: By providing the packaging sheet with the second silo mechanism 2, the product has improved protection strength after heat sealing, further avoiding damage to the rear shell, and improving the yield rate; based on the arrangement of the bottom film unwinding assembly 51, the face film unwinding assembly 52, the longitudinal sealing mechanism 7, and the transverse sealing mechanism 6, the product can be packaged in batches quickly, and based on the vacuuming effect of the vacuum rod 74 during longitudinal sealing, the fit between the face film 522 and the bottom film 512 is ensured, and the beauty of the product packaging is ensured. The present disclosure can automatically and efficiently realize the film packaging of the product.

[0039] Those skilled in the art will readily appreciate other embodiments of the present disclosure after considering the specification and practicing the invention disclosed herein.
