[0053] The material unloading and transferring mechanism 9 is used to drag the surface film 522 and the bottom film 512 so that they pass under the transverse sealing mechanism 6, the longitudinal sealing mechanism 7, and the cutting mechanism 8 in sequence.

[0054] In one embodiment, the first hopper mechanism 1 includes a hopper 12, a first jacking assembly 13, a material dividing assembly 14, a material picking and transplanting assembly 15 and a first transport line 16. The first jacking assembly 13 includes a jacking plate 131 arranged below the hopper 12, a first nut seat 132 and a first column 133 supporting the jacking plate 131, a first screw rod 135 and a first motor 134 for driving the first nut seat 132 to rise and fall; there are at least two material dividing assemblies 14, which are arranged on both sides of the hopper 12, and include a first cylinder 141 and a first support claw 142 driven by the first cylinder 141 to position the material tray 11; the first transport line 16 is arranged below the material dividing assembly 14 and is located on both sides of the first jacking assembly 13.

The material picking and transplanting assembly 15 includes a second cylinder 151 and a second support claw 152 driven by the second cylinder 151 to position the material tray 11.

[0055] In one embodiment, the second hopper 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 via a second column 23, and the packaging sheet is stored on the first support plate 24. The second column 23 passes through a base plate 25 and is connected to the first support plate 24. The base plate 25 is provided with a plurality of limiting columns 26. The plurality of limiting columns 26 are enclosed to form a positioning for the packaging sheet. The limiting columns 26 are provided with air holes 261. The second hopper mechanism 2 is installed on a 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 hopper mechanism 2, and the second hopper mechanism 2 is slidably mounted on the first guide rail 272.

[0056] In one embodiment, after the first transplanting robot 3 takes the product from the first silo mechanism 1 , it places the product on the secondary positioning platform 10 for positioning. The secondary positioning platform 10 has a positioning groove 101 that matches the product.

[0057] In one embodiment, a material receiving mechanism 17 is further provided below the loading area 100 of the first hopper mechanism 1. The material receiving mechanism 17 includes a lifting assembly 171 and a lifting base 172 driven by the lifting assembly 171. A fourth cylinder 173 is provided on the lifting base 172. The driving end of the fourth cylinder 173 is connected to a second support plate 174. The second support plate 174 is used to receive the material tray 11. After all the products in the material tray 11 are removed, the lifting assembly 171 drives the second support plate 174 to rise to a certain height. The fourth cylinder 173 then drives the second support plate 174 to rise a second time. The second support plate 174 receives the empty material tray 11. The first supporting claw 142 of the material removal and transplanting assembly 15 releases the material tray 11. The fourth cylinder 173 resets, the second support plate 174 descends, and the lifting assembly 171 then drives the second support plate 174 to continue descending.

[0058] 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 .

[0059] 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 a mounting seat 97. The mounting seat 97 is also connected to a belt 93. The two 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.

[0060] 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 provided on the top of the casing, and the exhaust devices are connected to the dust collecting device through a pipe.

[0061] When the vacuum packaging device is working, the following steps are included:

[0062] 1. Manually place the full material tray 11 into the material bin 12, and the first motor 134 of the first jacking 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, and then drives the jacking 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 one material tray 11 with the first jacking assembly 13. Then the first supporting claw 142 of the material dividing assembly 14 is driven back to its position 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 jacking assembly 13. The second cylinder 151 in the material picking and transplanting assembly 15 drives the second supporting claw 152 to catch the material tray 11, and the first transport line 16 moves the material picking and transplanting assembly 15 to the loading area.

[0063] 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 sheet can be a silicone sheet, which is used to cover the back shell product of the mobile phone to play a protective role. The packaging sheet of the second hopper mechanism 2 cooperates 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 sheet to rise. In this way, the second transplanting manipulator only needs to descend to a fixed height each time to accurately take materials.

[0064] 3. The first transfer robot automatically picks up two products from the material tray 11 arriving at the loading area and places them on the secondary positioning platform 10, so that the posture of the products is corrected, and then the products are placed 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 on it move together to the upper material position of the packaging sheet; at the same time, the second transfer robot picks up two sheets from the second hopper mechanism 2 and places them on top of the products; among them, the bottom film 512 is previously pulled from the first unwinding roller 511 to the bottom of the first pressing roller 513, 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.

[0065] 4. The conveyor belt 5 moves the product and the silicone to a certain distance, and the mask 522 is simultaneously unwound to cover the product. The mask 522 is pulled from the second unwinding roller 521 to the bottom of the second pressing roller 523, covering the product and the bottom film 512. After transverse and longitudinal heat sealing, the mask 522 is bonded to the bottom film 512.

[0066] 5. The product and the packaging sheet are pulled by the unloading and transferring mechanism to move the bottom film 512 and the face film 522 to the bottom of the transverse sealing mechanism 6, and the transverse seal is pressed down and heat-sealed, 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 film 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 film 522, and then the third motor drives the drive 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 film 522 to move.

[0067] 6. The clamping cylinder 91 in the blanking and transplanting assembly 9 moves the product to the bottom of the longitudinal sealing mechanism 7. The first second heating rod 72 presses down to heat-seal one side of the bottom film 512 and the face film 522. 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. In this way, 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.

[0068] 7. The 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.

[0069] 8. Since the blanking and transferring mechanism still holds one side of the bottom film 512 and the face film 522, the finished product can be moved to the blanking frame by continuing to move the blanking and transferring mechanism.

[0070] Beneficial effects:

[0071] By providing the encapsulating sheet with a second hopper mechanism 2, the product's protective strength is enhanced after heat sealing, further preventing damage to the rear shell and improving the yield rate. The configuration of the base film unwinding assembly 51, the face film unwinding assembly 52, the longitudinal sealing mechanism 7, and the transverse sealing mechanism 6 allows for rapid batch encapsulation of products. The vacuuming action of the vacuum rod 74 during longitudinal sealing ensures the proper fit between the face film 522 and the base film 512, ensuring the aesthetics of the product packaging. The present disclosure enables automated and efficient film encapsulation of products.
