Description

[Technical field]

[0001] The utility model relates to vacuum packaging equipment, in particular to vacuum packaging equipment for electronic products. [Background Technology]

[0002] Traditional semi-automatic vacuum packaging requires manual bagging and manual assistance in placing the products into a vacuum sealing machine to complete the sealing. This consumes a lot of manpower and the packaging is not very exquisite.

[0003] Application number CN202111221670.2 discloses an automatic vacuum packaging device for PCB boards. The device includes a feeding mechanism for conveying PCB boards, a measuring mechanism for measuring the dimensions of PCB boards, a test paper placement mechanism, several bag storage mechanisms, a bag-removing mechanism for placing and removing sealed bags and opening them, a bag-holding mechanism for holding the bag opening open, a bag-covering mechanism for placing PCB boards into the sealed bags, a desiccant loading mechanism for feeding desiccant into the bag-covering mechanism, and a vacuum sealing mechanism for evacuating and heat-sealing the sealed bags. The bag-holding mechanism includes two parallel support plates and a first linear motion mechanism for adjusting the reference spacing between the two support plates. The bag-covering mechanism includes two opposing L-shaped clamping plates and a second linear motion mechanism for adjusting the reference spacing between the two clamping plates. The inner sidewall front end of one clamping plate has a placement groove for placing desiccant, and a pushing mechanism for pushing the desiccant. This invention uses a fixed-height support plate to hold the bag opening open. While suitable for automatic vacuum packaging of thinner PCB boards, it is not well suited for vacuum packaging of electronic products of varying heights. In addition, the bag opening mechanism of the invention only has an upper suction cup group and no lower suction cup group, which can easily cause the bag opening to fail when the upper and lower parts of the bag are stuck together.

[0056] The working process of the electronic product vacuum packaging equipment in the above embodiment of the utility model includes the following steps

[0057] 1) Open the bag opening. The external bag loading robot places the bag on the bagging platform 61. The lower edge of the bag opening is pressed against the top surface of the vacuum suction cup 11 below the bag opening base 10. The bag opening suction cup robot 10A moves the upper vacuum suction cup 12 to the top of the bag opening. The upper vacuum suction cup 12 is pressed against the upper edge of the bag opening. The lower vacuum suction cup 11 sucks the lower edge of the bag opening, and the upper vacuum suction cup 12 sucks the upper edge of the bag opening. When the bag opening suction cup robot 10A lifts the upper vacuum suction cup 12, the upper and lower edges of the bag opening are separated, and the bag opening is opened.

[0058] 2) The upper support rod lifting devices 20B of the two bag opening assemblies 20 are activated, causing the two upper support rods 22 to descend and move closer to the lower support rods 23; the bag opening bracket longitudinal movement devices 20A of the two bag opening assemblies 20 are activated, causing the bag opening brackets 21 of the two bag opening assemblies 20 to move longitudinally forward simultaneously; the two upper support rods 22 and the two lower support rods 23 are inserted into the bag opening opened by the upper vacuum suction cup 12;

[0059] 3) Based on the set bag opening size, the transverse opening and closing assembly 30 simultaneously moves the bag opening brackets 21 of the two bag opening assemblies 20 outward, and the two upper support rods 22 and the two lower support rods 23 simultaneously expand outward; the upper support rod lifting devices 20B of the two bag opening assemblies 20 are activated, and the two upper support rods 22 rise and leave the lower support rods 23, raising the height of the bag opening; the opening width and opening height of the packaging bag reach the set requirements; the two L-shaped lower support rods 23 inserted into the bag opening form a slide for the electronic product to enter the packaging bag;

[0060] 4) An external workpiece loading robot or a human operator places the tray containing the electronic products (if the electronic products have a regular shape, a tray is not required) onto the rear of the slideway formed by the two L-shaped lower support rods 23;

[0061] 5) The second synchronous belt device 54, second slide cylinder 57, and third multi-rod cylinder 58 of the push plate longitudinal drive unit 50A are activated, causing the push plate 51 to move forward, pushing the tray containing the electronic products into the packaging bag on the bagging platform 61. The exhaust flat tube 59 moves forward along with the cylinder bracket 56, and its front end is inserted into the bag opening. The second slide cylinder 57 and third multi-rod cylinder 58 drive the push plate 51 to move backward, away from the packaging bag, but the front end of the exhaust flat tube 59 remains in the bag opening.

[0062] 6) The transverse opening and closing assembly 30 simultaneously moves the bag opening brackets 21 of the two bag opening assemblies 20 inward, and the two upper support rods 22 and the two lower support rods 23 are simultaneously retracted; the bag opening bracket longitudinal movement devices 20A of the two bag opening assemblies 20 are actuated, and the bag opening brackets 21 of the two bag opening assemblies 20 simultaneously retreat and detach from the bag opening of the packaging bag;

[0063] 7) The two bag-opening assemblies 40 operate simultaneously, and the bag-opening rods 44 of the two bag-opening assemblies 40 are inserted into the bag opening. The platform lifting device operates, and the bagging platform 61 descends until the height of the electronic products in the bag is located in the middle of the flattened bag opening. The transverse opening and closing assembly 30 simultaneously moves the bag-opening brackets 21 of the two bag-opening assemblies 20 outward, and the two bag-opening rods 44 simultaneously expand outward, flattening the bag opening.

[0064] 8) The bag opening clamping assemblies 70 are actuated, and the two bag opening clamping assemblies 70 clamp the flattened bag opening. The bag opening clamped by the two bag opening clamping assemblies 70 is located in front of the two bag support rods 44 and the heat sealing lower clamp 90;

[0065] 9) The heat sealing assembly 80 is moved. The longitudinal motion device 80A and the vertical motion device 80B move the strip-shaped heating block 881 of the upper heat sealing clamp 80C and the upper sealing bead 89 to the top of the bag opening. The two lifting cylinders 94 of the lower heat sealing clamp 90 are actuated, and the lower sealing bead 93 is lifted to clamp the bag opening with the upper sealing bead 89 to seal the bag opening. The external vacuum generator generates negative pressure to evacuate the bag through the vacuum flat tube 59. After the bag is evacuated, the second synchronous belt device 54 driven by the motor is actuated again, and the vacuum flat tube 59 is pulled out of the bag opening through the connecting plate 55 and the cylinder bracket 56.

[0066] 10) The piston rod of the pressure cylinder 882 of the heating block pressure device extends downward, and the high-temperature strip heating block 881 descends, clamping the bag opening with the strip heat sealing support block 92 of the heat sealing lower clamp 90 and heat sealing it.

[0067] The bag opening assembly of the vacuum packaging equipment of the above embodiment of the present invention can conveniently adjust the bag opening height through the upper support rod lifting device, and can conveniently adapt to the needs of packaging electronic products of different heights.

[0068] The vacuum packaging equipment of the above embodiment of the present invention opens the bag opening by sucking the upper and lower edges of the bag opening of the packaging bag respectively through the lower vacuum suction cup and the upper vacuum suction cup, and the failure of the bag opening to open will not occur.
