Description

Technical Field

[0001] This invention relates to the field of workpiece packaging technology, specifically to an automatic workpiece packaging device and packaging method. Background Technology

[0002] In the existing technology of workpiece packaging, the packaging operation of bagging and sealing workpieces usually relies on manual operation or segmented semi-automatic equipment.

[0003] Manual packaging, which involves packaging and sealing workpieces manually, is not only inefficient and labor-intensive, but also produces inconsistent packaging quality, making it difficult to achieve large-scale, continuous production.

[0004] Common segmented semi-automatic packaging equipment typically combines single-process operations such as bag picking, bag opening, filling, and sealing. The connection between processes requires manual intervention or is achieved by combining multiple machines. This not only results in a cumbersome overall process, large footprint, and poor coordination efficiency, but also easily leads to problems such as bag damage, incomplete workpiece filling, and loose sealing due to inaccurate alignment and unstable bag opening and closing, affecting the consistency and quality of the produced workpiece packages.

[0016] The present invention also provides a packaging method for an automatic workpiece packaging device, comprising the following:

[0017] During the bag retrieval operation: The electronic control unit controls the z-axis sliding component to drive the packaging bag storage box to adjust to correspond with the flipping bag retrieval component along the y-axis direction, and then controls the flipping bag retrieval component to pick up the packaging bag in the packaging bag storage box.

[0019] During the bag-holding operation: The x-axis sliding module is driven again to move the first bag-holding component along the x-axis direction until it is aligned with the second bag-holding component along the z-axis direction.

[0022] This invention patent, through the design of a heat-sealing mechanism, achieves integrated automated packaging operations encompassing bag picking, bag opening, component loading, and sealing. Specifically, the bag picking component picks up a packaging bag from the bag storage box and transfers it to the first bag opening component. The movement of the Z-axis sliding component causes the first bag opening component and the bag it holds to move synchronously to align with the second bag opening component. The second bag opening component, in conjunction with the first, opens the packaging bag. The workpiece is then fed into the opened bag from the bag's inlet. The bottom of the bag is supported by a rotating outlet component. The heat-sealing component then heat-seals the opening of the bag. Finally, the rotating outlet component outputs the packaged workpiece from the workpiece outlet. This improves packaging efficiency and consistency, replaces traditional manual operation, ensures the reliability of packaging actions and the stability of packaging quality, effectively enhances the overall level of intelligence, and further guarantees the quality of the produced workpiece packages.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0036] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly set on the other component; when a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to the other component.

[0037] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0038] Please refer to Figures 1-7The present invention provides an automatic workpiece packaging device, comprising: a box body 1, a workpiece inlet 2 disposed on the top of the box body 1, a workpiece outlet 3 disposed on the side of the box body 1, a heat sealing mechanism disposed inside the box body 1, and an electrical control unit 5 disposed inside the box body 1 via an isolation plate.

[0039] The heat sealing mechanism includes: a packaging bag storage box 42 installed inside the housing 1 via a z-axis sliding assembly 41; a flipping bag-retrieving assembly 43 installed above the packaging bag storage box 42; an x-axis sliding module 44 installed inside the housing 1; a first bag-supporting assembly 45 installed on the x-axis sliding module 44; a second bag-supporting assembly 46 installed corresponding to the first bag-supporting assembly 45; a heat sealing assembly 47 installed on the inner wall of the housing 1 near the second bag-supporting assembly 46 via a U-shaped mounting piece 49; and a rotating discharge assembly 48 corresponding to the workpiece discharge port 3.

[0040] To further explain, the z-axis sliding assembly 41 includes: a z-axis mounting frame 411 installed inside the housing 1, a z-axis telescopic motor 412 installed on the z-axis mounting frame 411, two parallel z-axis slide rails 413 arranged along the z-axis direction on the z-axis mounting frame 411, and a z-axis sliding member 414 slidably installed on the two z-axis slide rails 413. The telescopic end of the z-axis telescopic motor 412 is connected to the packaging bag storage box 42, and the packaging bag storage box 42 is installed on the z-axis sliding member 414.

[0041] This embodiment achieves integrated automatic packaging operations of bag picking, bag opening, loading, and sealing through the heat-sealing mechanism. Specifically, the flipping bag picking component 43 picks up the packaging bag from the packaging bag storage box 42 and then transfers it to the first bag opening component 45. The movement of the z-axis sliding component 41 drives the first bag opening component 45 and the attached packaging bag to move synchronously to align with the second bag opening component 46. The second bag opening component 46 works in conjunction with the first bag opening component 45 to open the packaging bag. At this point, the workpiece is fed from the bag's inlet into the opened bag. The bottom of the bag is supported by the rotating discharge component 48. The heat-sealing component 47 then heat-seals the opening of the bag. Finally, the rotating discharge component 48 outputs the packaged workpiece from the workpiece outlet 3. This improves packaging efficiency and consistency, replaces traditional manual operation, ensures the reliability of packaging actions and the stability of packaging quality, effectively enhances the overall level of intelligence, and further guarantees the quality of the produced workpiece packages.

[0042] In this embodiment, the electronic control unit 5 first controls the first bag-supporting assembly 45 to move to a position aligned with the flip-and-take bag assembly 43, starts the z-axis telescopic motor 412, pushes the packaging bag storage box 42 to move along the z-axis direction, and then drives the z-axis slider 414 to slide on the z-axis slide rail 413 to ensure the stability of the movement of the packaging bag storage box 42. When the packaging bag storage box 42 is adjusted to be aligned with the flip-and-take bag assembly 43, the drive of the z-axis telescopic motor 412 is stopped, and then the flip-and-take bag assembly 43 is controlled to pick up the packaging bag in the packaging bag storage box 42. Subsequently, the flip-and-take bag assembly 43 docks the picked-up packaging bag with the first bag-supporting assembly 45, controls the x-axis sliding module 44 to move, and drives the first bag-supporting assembly 45 and the packaging bag adsorbed on it to move synchronously to be aligned with the second bag-supporting assembly 46, and controls the second bag-supporting assembly 46 to adsorb the packaging bag. At this time, the first bag-supporting assembly 45 and the second bag-supporting assembly 46 cooperate to open the packaging bag, making the inlet of the packaging bag open, and the inlet of the packaging bag is aligned with the workpiece inlet 2 along the y-axis. The workpiece is fed into the packaging bag from the workpiece inlet 2, and then the first bag-supporting assembly 45 and the second bag-supporting assembly 46 are adjusted synchronously to adaptively close the inlet of the packaging bag. The heat-sealing assembly 47 is controlled to heat-seal the inlet of the packaging bag. After heat-sealing, both the first bag-supporting assembly 45 and the second bag-supporting assembly 46 release their suction on the packaging bag, and the workpiece package is output from the workpiece outlet 3 by rotating the discharge assembly 48.

[0043] To further explain, several packaging bags are stacked sequentially along the z-axis inside the packaging bag storage box 42. The packaging bag storage box 42 is equipped with clips to restrict the packaging bags, ensuring that the flipping and bag-picking component 43 can only pick up one packaging bag at a time.

[0044] like Figure 3 and Figure 5 As shown, the flip-over bag-retrieving assembly 43 includes: a first bracket 431 and a second bracket 432 respectively disposed on both sides of the packaging bag storage box 42, a first rotating motor 433 mounted on the first bracket 431, a first support member 434 coaxially mounted with the output shaft of the first rotating motor 433, a first bearing seat 435 mounted on the second bracket 432, a rotating telescopic motor 436 mounted on the first support member 434, and a suction cup member 437 mounted on the telescopic end of the rotating telescopic motor 436. The end of the first support member 434 is mounted on the first bearing seat 435.

[0045] The first rotating motor 433 drives the first support member 434 to rotate, and the rotating telescopic motor 436 changes to a parallel state along the y-axis direction, so that the suction cup member 437 is aligned with the packaging bag in the packaging bag storage box 42.

[0046] In this embodiment, the first bag-supporting assembly 45 is controlled to move until it is aligned with the flip-and-take bag assembly 43 along the z-axis. When the packaging bag storage box 42 is adjusted to the bottom of the flip-and-take bag assembly 43, the first rotating motor 433 is started. With the cooperation of the first bearing seat 435, the first support member 434 rotates accordingly. The rotating telescopic motor 436 is adjusted until the suction cup member 437 is aligned with the packaging bag storage box 42 along the y-axis. Then, the rotating telescopic motor 436 is started so that the suction cup member 437 can extend and retract to suck up the packaging bag in the packaging bag storage box 42. After sucking up the packaging bag, the first rotating motor 433 is controlled to rotate the rotating telescopic motor 436 until it is aligned with the first bag-supporting assembly 45 along the z-axis. The first bag-supporting assembly 45 is controlled to suck up the packaging bag. Then, the suction cup member 437 is controlled to release the packaging bag, completing the retrieval and handover of the packaging bag.

[0047] like Figure 4 As shown, the x-axis sliding module 44 includes: an x-axis mounting frame 441 installed in the housing 1 along the x-axis direction, an x-axis motor 442 installed on the x-axis mounting frame 441, an x-axis slide rail 443 coaxially installed with the output shaft of the x-axis motor 442, and a plurality of x-axis sliders 444 slidably installed with the x-axis slide rail 443, and a first support bag assembly 45 is installed on the x-axis sliders 444.

[0048] In this embodiment, the x-axis motor 442 is started, causing the x-axis slider 444 to slide on the x-axis slide rail 443, and driving the first bag support assembly 45 mounted on the x-axis slider 444 to move synchronously, thereby adjusting the position of the first bag support assembly 45 so that the first bag support assembly 45 after adsorbing the packaging bag is moved to a position aligned with the second bag support assembly 46, thus completing the transportation of the packaging bag.

[0049] like Figure 3 and Figure 7 As shown, the first bag-supporting assembly 45 includes: a first bag-supporting telescopic motor 451 mounted on the x-axis sliding module 44, a first suction cup mounting plate 452 mounted on the telescopic end of the first bag-supporting telescopic motor 451, and a plurality of first suction cups 453 mounted on the suction cup mounting plate; when the flip-to-take-bag assembly 43 picks up the packaging bag, the x-axis sliding module 44 controls the first bag-supporting assembly 45 to move to be aligned with the flip-to-take-bag assembly 43 along the z-axis direction, and the first bag-supporting telescopic motor 451 controls the plurality of first suction cups 453 to pick up the packaging bag.

[0050] Furthermore, the second bag-supporting assembly 46 includes: a second bag-supporting telescopic motor 462 installed inside the housing 1 via a fixing frame 461; a second suction cup mounting plate 463 installed at the telescopic end of the second bag-supporting telescopic motor 462; and a plurality of second suction cups 464 installed on the second suction cup mounting plate 463; the first suction cup mounting plate 452 is aligned with the first suction cup mounting plate 452, and the plurality of first suction cups 453 and second suction cups 464 open the packaging bag.

[0051] In this embodiment, the x-axis motor 442 is driven to rotate forward, causing the x-axis slider 444 to slide on the x-axis slide rail 443. This causes the first bag-supporting assembly 45 to move as a whole until it aligns with the suction cup 437 that has picked up the packaging bag along the z-axis. Then, the first bag-supporting telescopic motor 451 is activated to control the first suction cup mounting plate 452 to move towards the suction cup 437 as its telescopic end extends. This causes the first suction cups 453 on the first suction cup mounting plate 452 to pick up the packaging bag. Subsequently, the suction cup 437 is controlled to release its grip on the packaging bag, completing the transfer of the packaging bag. Then, the x-axis motor 442 is driven to rotate in the reverse direction, causing the x-axis slider 444 to move the first bag-supporting assembly 45 and the packaging bag picked up by the first suction cups 453 along the x-axis towards the second bag-supporting assembly 46 on the x-axis slide rail 443. When the first bag-supporting assembly 45 moves to be aligned with the second bag-supporting assembly 46 along the z-axis, the rotation of the x-axis motor 442 is stopped. The second bag-supporting telescopic motor 462 is driven, causing the second suction cup mounting plate 463 to move along the z-axis with its telescopic end, and causing several second suction cups 464 to adhere to the packaging bag. By synchronously adjusting the telescopic ends of the first bag-supporting telescopic motor 451 and the second bag-supporting telescopic motor 462 to retract, the packaging bag adhered by the first suction cups 453 and the second suction cups 464 is converted to an open state. The bottom of the workpiece inlet 2 is directly opposite the open packaging bag. At this time, all workpieces input from the workpiece inlet 2 can be received by the packaging bag, and then the packaging bag is heat-sealed by the heat-sealing assembly 47. The packaged workpiece is then output from the workpiece outlet 3 by rotating the discharge assembly 48.

[0052] To further explain, the first bag-supporting assembly 45 uses the first suction cup 453 to adsorb the packaging bag, thereby transferring the packaging bag along the z-axis. The second bag-supporting assembly 46 is used as a moving reference and moves to a position aligned with the second bag-supporting assembly 46 along the z-axis under the action of the x-axis sliding module 44. The bag-supporting action is completed through the cooperation of the first bag-supporting assembly 45 and the second bag-supporting assembly 46, forming a stable open state to receive the workpiece, improving packaging efficiency and consistency, significantly reducing manual intervention, and ensuring production continuity and packaging quality.

[0053] like Figure 5 and Figure 7As shown, the heat sealing assembly 47 includes: a first heat sealing telescopic motor 471 and a second heat sealing telescopic motor 472 respectively mounted on the extended end of the U-shaped mounting member 49 along the z-axis direction; a first heat sealing component 473 mounted on the telescopic end of the first heat sealing telescopic motor 471; and a second heat sealing component 474 mounted on the telescopic end of the second heat sealing telescopic motor 472. The first heat sealing component 473 and the second heat sealing component 474 are arranged opposite to each other.

[0054] To further explain, the first suction cup mounting plate 452 is provided with a first groove that mates with the first heat sealer 473, and the second suction cup mounting plate 463 is provided with a second groove that mates with the second heat sealer 474; several first suction cups 453 and second suction cups 464 work together to open the packaging bag, and the inlet of the packaging bag is aligned with the workpiece inlet 2. When the workpiece is completely loaded into the packaging bag, the first heat sealer 473 and the second heat sealer 474 are controlled to heat seal the inlet of the packaging bag.

[0055] In this embodiment, the first bag-supporting assembly 45 and the second bag-supporting assembly 46 cooperate to open the packaging bag. When the workpiece is fed into the packaging bag from the workpiece inlet 2, the telescopic ends of the first bag-supporting telescopic motor 451 and the second bag-supporting telescopic motor 462 are driven to extend synchronously, causing the first suction cup mounting plate 452 and the second suction cup mounting plate 463 to move relative to each other, so that the inlet of the packaging bag is closed adaptively. Subsequently, the telescopic ends of the first heat-sealing telescopic motor 471 and the second heat-sealing telescopic motor 472 are driven to extend synchronously. When the first heat-sealing component 473 and the second heat-sealing component 474 move to abut against each other, the opening of the packaging bag is sandwiched between the first heat-sealing component 473 and the second heat-sealing component 474, and stays for 1 to 2 seconds to fully heat-seal the inlet of the packaging bag. Then, the telescopic ends of the first bag-supporting telescopic motor 451 and the second bag-supporting telescopic motor 462 are controlled to retract synchronously, driving the first heat-sealing component 473 and the second heat-sealing component 474 to leave the packaging bag, completing the heat sealing of the opening of the packaging bag.

[0056] To further explain, the first suction cup mounting plate 452 is provided with a first groove that mates with the first heat sealer 473, and the second suction cup mounting plate 463 is provided with a second groove that mates with the second heat sealer 474; several first suction cups 453 and second suction cups 464 work together to open the packaging bag, and the inlet of the packaging bag is aligned with the workpiece inlet 2. When the part is completely loaded into the packaging bag, the first heat sealer 473 and the second heat sealer 474 are controlled to heat seal the inlet of the packaging bag.

[0057] The first heat-sealing element 473 is coplanar with the first groove along the z-axis. When both the first bag-supporting telescopic motor 451 and the first heat-sealing telescopic motor 471 are in the retracted state, the first heat-sealing element 473 is located within the first groove. Therefore, the movements of the first suction cup mounting plate 452 and the first heat-sealing element 473 are parallel and do not affect each other. The second heat-sealing element 474 is coplanar with the second groove along the z-axis. When both the second bag-supporting telescopic motor 462 and the second heat-sealing telescopic motor 472 are in the retracted state, the second heat-sealing element 474 is located within the second groove. Therefore, the movements of the second suction cup mounting plate 463 and the second heat-sealing element 474 are parallel and do not affect each other.

[0058] like Figure 6 As shown, the rotating discharge assembly 48 includes: a support frame 481 corresponding to the bottom of the heat sealing assembly 47, a second rotating motor 482 mounted on the support frame 481, a second support member 483 coaxially mounted with the output shaft of the second rotating motor 482, a second bearing seat 484 mounted on the end of the second support member 483 for support, a discharge rotating plate 485 mounted on the second support member 483, and a discharge channel 486 disposed between the discharge rotating plate 485 and the workpiece discharge port 3; the discharge rotating plate 485 supports the packaging bag, the second rotating motor 482 controls the discharge rotating plate 485 to rotate toward the discharge channel 486, and the sealed workpiece package is output from the workpiece discharge port 3 through the discharge channel 486.

[0059] In this embodiment, the discharge plate 485 is used to support the packaging bag that has been loaded with workpieces, is waiting or has been sealed, to ensure that the packaging bag will not be damaged by gravity after the workpiece is fed into the packaging bag, and the workpiece inside the packaging bag will not fall out.

[0060] To further explain, after the first heat-sealing assembly 47 and the second heat-sealing assembly 47 seal the packaging bag, several first suction cups 453 and second suction cups 464 are controlled to release their adsorption on the packaging bag. Then, the first bag-supporting telescopic motor 451 and the second bag-supporting telescopic motor 462 are driven to retract synchronously. At this time, the sealed workpiece package is in an unrestrained state. Then, the second rotation motor 482 is started to rotate forward, causing the second support member 483 to rotate forward as well. With the cooperation of the second bearing seat 484, the discharge turntable 485 rotates to the side of the discharge channel 486, so that the unrestrained workpiece package on the discharge turntable falls into the discharge channel 486 and is smoothly output from the workpiece discharge port 3 through the inclined discharge channel 486.

[0061] Furthermore, the electronic control unit 5 is used to control the start-up and movement of various components inside the box 1, realizing automated packaging operations without manual assistance, and further improving the accuracy of workpiece packaging.

[0062] Furthermore, the bottom of the housing 1 is equipped with several casters 6 for movement, which can assist in the movement of the entire device.

[0063] Furthermore, a feeding funnel 7 is provided outside the workpiece inlet 2 to assist in feeding. This funnel can guide and directionally transport the workpiece, ensuring that the workpiece is smoothly and accurately fed into the packaging bag. This further improves the stability and continuity of feeding, reduces material jamming and splashing, and enhances feeding efficiency.

[0064] Furthermore, the housing 1 is equipped with a wire trough, through which the output wires of each motor are run and connected to the electrical control unit 5, ensuring the neatness of the internal layout of the housing 1.

[0065] like Figures 1-7 As shown, the present invention also provides a packaging method for an automatic workpiece packaging device, comprising the following:

[0066] During the bag retrieval operation: The electronic control unit 5 controls the z-axis sliding component 41 to drive the packaging bag storage box 42 to adjust to correspond with the flipping bag retrieval component 43 along the y-axis direction, and then controls the flipping bag retrieval component 43 to pick up the packaging bag in the packaging bag storage box 42.

[0067] Drive the x-axis sliding module 44 so that the first bag support assembly 45 moves to correspond with the flip bag taking assembly 43 along the z-axis direction. Then control the flip bag taking assembly 43 to transfer the picked-up packaging bag to the first bag support assembly 45, and the first bag support assembly 45 simultaneously adsorbs and receives the packaging bag.

[0068] During the bag-holding operation: the x-axis sliding module 44 is driven again, so that the first bag-holding component 45 moves along the x-axis direction to be aligned with the second bag-holding component 46 along the z-axis direction. Then, the second bag-holding component 46 adsorbs the packaging bag and works with the first bag-holding component 45 to open the inlet of the packaging bag.

[0069] During the heat sealing and unloading operation: the first bag support assembly 45 and the second bag support assembly 46 are controlled to adaptively close the inlet of the packaging bag, the heat sealing assembly 47 is controlled to seal the inlet of the packaging bag, and then the rotating unloading assembly 48 is controlled to output the sealed workpiece package from the workpiece unloading port 3.

[0070] In this embodiment, the specific details are as follows:

[0071] To perform the bag retrieval operation: The electronic control unit 5 controls the start of the z-axis telescopic motor 412, which pushes the packaging bag storage box 42 to move along the z-axis direction, thereby driving the z-axis slider 414 to slide on the z-axis slide rail 413. When the packaging bag storage box 42 is adjusted to be aligned with the bottom of the flipping bag retrieval component 43, the drive of the z-axis telescopic motor 412 is stopped.

[0072] Start the first rotating motor 433 to make the first support member 434 rotate synchronously. Adjust the telescopic end of the rotating telescopic motor 436 to face the packaging bag storage box 42 along the y-axis. Start the rotating telescopic motor 436. The extension of the telescopic end drives the suction cup member 437 to move into the storage box and suck up the packaging bag in the packaging bag storage box 42. Control the telescopic end of the rotating telescopic motor 436 to retract appropriately. Then start the first rotating motor 433 again. Adjust the telescopic end of the rotating telescopic motor 436 to face the x-axis sliding module 44 along the z-axis. Then stop the first rotating motor 433.

[0073] To perform the bag-holding operation: Start the x-axis motor 442. The output shaft of the x-axis motor 442 rotates in the forward direction to control the x-axis slider 444 to slide on the x-axis slide rail 443, which drives the first bag-holding assembly 45 to slide towards the flip-up bag-taking assembly 43. When the first suction cup mounting plate 452 and the suction cup 437 are aligned along the z-axis, the output of the x-axis motor 442 is stopped.

[0074] The first bag-supporting telescopic motor 451 is activated, causing the telescopic end to extend and control the first suction cup mounting plate 452 to move along the z-axis. The first suction cups 453 then pick up the packaging bag from the suction cup component 437, and the suction cup component 437 releases its grip on the packaging bag. The x-axis motor 442 is activated, and the output shaft of the x-axis motor 442 rotates in the opposite direction to control the x-axis slider 444 to slide on the x-axis slide rail 443. This causes the first bag-supporting assembly 45 and the packaging bag adsorbed on the first suction cups 453 to slide towards the second bag-supporting assembly 46. When the first bag-supporting assembly 45 and the second bag-supporting assembly 46 are aligned along the z-axis, the x-axis motor 442 is stopped. At this time, the first heat-sealing component 473 is embedded in the first groove.

[0075] Start the second bag-supporting telescopic motor 462. The telescopic end of the second bag-supporting telescopic motor 462 extends, controlling the second suction cup mounting plate 463 to move along the z-axis towards the first suction cup mounting plate 452. The packaging bag is then adsorbed by several second suction cups 464. The first bag-supporting telescopic motor 451 and the second bag-supporting telescopic motor 462 are adjusted synchronously to make the packaging bag open. At this time, the inlet of the packaging bag is directly opposite the workpiece inlet 2.

[0076] The sealing operation of the workpiece package is performed as follows: The workpiece is fed into the packaging bag through the workpiece inlet 2. The first bag-supporting telescopic motor 451 and the second bag-supporting telescopic motor 462 are started, causing their telescopic ends to extend synchronously. This drives the first suction cup mounting plate 452 and the second suction cup mounting plate 463 to move synchronously relative to each other, controlling the adaptive closure of the packaging bag's inlet. Subsequently, the telescopic ends of the first heat-sealing telescopic motor 471 and the second heat-sealing telescopic motor 472 are controlled to extend synchronously, causing the first heat-sealing component 473 and the second heat-sealing component 474 to move synchronously relative to each other. The process involves sealing the inlet of the packaging bag. When the first heat-sealing component 473 and the second heat-sealing component 474 move to a point where they block each other, they pause for 1 to 2 seconds. Then, the telescopic ends of the first heat-sealing telescopic motor 471 and the second heat-sealing telescopic motor 472 are controlled to retract synchronously. At this time, the inlet of the packaging bag has been sealed. During this process, several first suction cups 453 and second suction cups 464 do not release their suction on the packaging bag to ensure the stability of the heat seal. The bottom of the packaging bag abuts against the discharge turntable 485 to support the packaging bag.

[0077] The workpiece unloading operation is performed by controlling several first suction cups 453 and second suction cups 464 to release their adsorption on the packaging bag, and controlling the extension ends of the first bag-supporting telescopic motor 451 and the second bag-supporting telescopic motor 462 to retract. Then, the second rotating motor 482 is started, so that the second support member 483 rotates synchronously, driving the discharge plate 485 to rotate towards the discharge channel 486, and outputting the sealed workpiece package located on the discharge plate 485 through the workpiece discharge port 3 along the discharge channel 486, thus completing the workpiece packaging operation.

[0078] It should be understood that the specific embodiments described above are for illustrative purposes only and are not intended to limit the scope of the invention. Obvious variations or modifications derived from the spirit of the invention are still within the scope of protection of the invention.
