Description

Technical Field

[0001] This invention relates to the field of packaging technology, and more specifically to packaging equipment. Background Technology

[0002] Currently, the packaging process for printed circuit board assemblies (PCBAs) mainly relies on manual operation. Workers need to perform repetitive and tedious manual operations for long periods of time, which increases their labor intensity and easily leads to fatigue and decreased efficiency. At the same time, it is difficult to maintain a high level of operational accuracy for extended periods of time, affecting the overall quality and efficiency of packaging. Furthermore, since it is difficult to completely avoid physical contact with the product during manual handling, the risk of damage to the printed circuit board assemblies is directly increased. Summary of the Invention

[0003] In view of this, the present invention provides a packaging device to solve the problem of low packaging efficiency of manual packaging.

[0004] This invention provides a packaging device, including a first packaging mechanism, an inflation protection mechanism, a moving mechanism, and a second packaging mechanism. The first packaging mechanism includes an inner protective bag and is used to encapsulate a board to be packaged in the inner protective bag to form a first component. The inflation protection mechanism is disposed adjacent to the first packaging mechanism and connected to the inner protective bag, and is used to fill the first component with gas to form a second component and to extract the gas from the second component to form a third component. The moving mechanism is disposed adjacent to the first packaging mechanism and is provided with movable grippers. The second packaging mechanism is located downstream of the first packaging mechanism and is disposed adjacent to the moving mechanism, and includes an outer protective film. The grippers grasp the second component and place it on the second packaging mechanism, and the second packaging mechanism is used to wrap the third component inside the outer protective film.

[0005] The first packaging mechanism seals the board to be packaged in an inner protective bag, while a second packaging mechanism wraps an outer protective film around the inner protective bag, achieving double protection for the board. A moving mechanism transfers the second component to the second packaging mechanism. An inflation protection mechanism inflates the first component to form the second component. This significantly reduces friction between the inner protective bag and the board during the movement of the second component to the second packaging mechanism, protecting the board's surface from damage. It also effectively mitigates vibration and impact during movement, further enhancing the protective effect. Through the combination of the first packaging mechanism, inflation protection mechanism, moving mechanism, and second packaging mechanism, automated packaging of the board is achieved, significantly reducing the labor intensity of workers and greatly improving packaging efficiency and final packaging quality.

[0006] In one optional embodiment, the second packaging mechanism further includes a limiting component, which includes a driving mechanism and two limiting members. The two limiting members are arranged opposite to each other and spaced apart along a first direction. The driving mechanism is tractively connected to both limiting members. Under the drive of the driving mechanism, the two limiting members have a first position where they are far apart from each other and a second position where they are close to each other. The second packaging mechanism and the first packaging mechanism are arranged sequentially along a second direction. The outer protective film includes a first protective film and a second protective film that are connected to each other. The connection between the first protective film and the second protective film is located between the two limiting members. When the limiting member is in the first position, the first protective film and the second protective film are both arranged parallel to the first direction and are respectively located at the top of the two limiting members. When the limiting member is in the second position, the first protective film and the second protective film are located between the two limiting members and are both arranged perpendicular to the first direction. The first direction is perpendicular to the second direction.

[0007] By setting two limiting members, the outer protective film can be supported and limited. When the limiting members are in the first position, the first and second protective films are located on top of the two limiting members, which can support the first and second protective films. The moving mechanism can place the second component between the first and second protective films to prepare for subsequent packaging steps. During the process of the limiting members moving to the second position, the connection between the first and second protective films descends together with the third component. The ends of the first and second protective films away from the connection gradually move closer and gradually wrap around the two sides of the third component along the first direction, reducing friction between the outer protective film and the inner protective bag.

[0008] In one optional embodiment, a control system is further included, which is communicatively connected to the moving mechanism; the limiting component further includes a placement plate and a first pressure sensor; the placement plate is fixed to one side of the bottom of the limiting member, and both limiting members are slidably connected to the placement plate; the first pressure sensor is located between the two limiting members, fixed on the placement plate, and communicatively connected to the control system; when the two limiting members approach each other, the control system controls the gripper to move the third component closer to the placement plate; when the pressure between the outer protective film and the first pressure sensor reaches a set value, the control system controls the gripper to move away from the placement plate.

[0009] By setting a placement plate, when the two limiting members are in the second position and the first and second protective films are located between the two limiting members, the placement plate can support and limit the first and second protective films, which helps to support and fix the outer protective film, prevent the first and second protective films from falling off, and achieve the stable placement of the third component between the first and second protective films. Furthermore, by setting a first pressure sensor on the placement plate, when the pressure between the outer protective film and the first pressure sensor reaches a set value, the control system controls the gripper to move away from the placement plate, preventing the gripper from continuing to push the third component closer to the placement plate, thereby effectively avoiding damage to the packaging board in the third component due to excessive compression. By setting up a control system, a placement plate, and a first pressure sensor, not only is the stability of the packaging enhanced, but the automation level and safety of the entire packaging process are also significantly improved.

[0010] In one optional embodiment, a control system is also included, which is communicatively connected to the drive mechanism; the limiting component further includes two second pressure sensors, which are respectively disposed on the side of the two limiting components that are close to each other, and both are communicatively connected to the control system; when the pressure between the second pressure sensor and the outer protective membrane reaches a set value, the control system controls the drive mechanism to stop driving.

[0011] When the two limiting members are close to each other in the second position, the third component and the outer protective film are both located between the two limiting members. By setting two pressure sensors on the side where the two limiting members are close to each other, when the pressure between the second pressure sensor and the outer protective film reaches a set value, the control system controls the drive mechanism to stop driving, preventing the two limiting members from continuing to approach each other and squeezing the third component, avoiding possible squeezing damage to the packaging board, and ensuring the product yield. By setting the second pressure sensor, not only is the accuracy of packaging improved, but the safety and reliability of the entire packaging process are also significantly enhanced.

[0012] In one optional embodiment, the second packaging mechanism further includes two sets of limiting rollers, which are movably disposed above the two limiting members. When the limiting members are in the first position, the limiting rollers abut against the top of the outer protective film. When the limiting members move from the first position to the first position, the limiting rollers rotate away from the outer protective film.

[0013] By setting a limiting roller, when the limiting component is in the first position, the limiting roller abuts against the top of the outer protective film. This not only enhances the stability of the outer protective film but also, through its synergistic effect with the limiting component, effectively prevents the outer protective film from accidentally detaching from the limiting component, thus ensuring the accuracy and reliability of the packaging. When the limiting component moves from the first position to the second position, the limiting roller rotates away from the outer protective film, avoiding any obstruction caused by the limiting roller during the rotation of the first or second protective film to the position between the two limiting components. Setting a limiting roller not only improves the automation level of packaging but also ensures the stability and smoothness of the entire packaging process.

[0014] In one optional embodiment, the second packaging mechanism further includes a swing assembly, which includes a swing shaft, a swing gear, and a first lifting assembly. The swing shaft is disposed adjacent to the outer protective film along a second direction, rotatably disposed on top of the limiting member, and extends along a first direction. The limiting roller is rotatably connected to the swing shaft and disposed perpendicular to the swing shaft. The swing gear is sleeved on the outer periphery of the swing shaft and fixedly connected to it. The first lifting assembly is disposed on the side of the swing shaft away from the outer protective film, and the lifting end of the first lifting assembly meshes with the swing gear. The moving mechanism includes a drive rod, which is fixed to the side of the gripper along the second direction. When the gripper descends, the drive rod drives the lifting end of the first lifting assembly to descend, and the limiting roller rotates away from the outer protective film.

[0015] By setting up a swing assembly, the rotation of the limit roller toward the side away from the outer protective film is achieved; when the lifting end of the first lifting assembly descends and drives the swing gear to rotate, the swing shaft rotates synchronously. Since the limit roller is set perpendicular to the swing shaft, as the swing shaft rotates, the limit roller will rotate toward the side away from the outer protective film.

[0016] In one optional embodiment, the first lifting assembly includes a fixed block, a lifting block, a first elastic connector, and a magnetic component; the fixed block is fixed to the limiting component; the lifting block is located above the fixed block and meshes with the swing gear; the first elastic connector is connected between the fixed block and the lifting block; when the limiting roller abuts against the top of the outer protective film, the first elastic connector is in an extended state; when the limiting roller rotates away from the outer protective film, the first elastic connector is in a retracted state; the magnetic component is fixed to the bottom of the lifting block for magnetic connection with the top of the fixed block.

[0017] Because a first elastic connector is connected between the fixed block and the lifting block, and the first elastic connector is in an extended state when the limiting roller abuts against the top of the outer protective film, the first elastic connector can support the lifting block, ensuring that the limiting roller is in contact with the outer protective film. When the limiting roller rotates away from the outer protective film, the lifting block descends and compresses the first elastic connector, driving the limiting roller to rotate away from the outer protective film. By setting a magnetic component, when the lifting block descends to abut against the fixed block, the magnetic component can fix the lifting block, ensuring that the limiting roller is always separated from the outer protective film during subsequent packaging. The setting of the fixed block, lifting block, first elastic connector, and magnetic component not only enhances the stability of the system, but also ensures that the limiting roller can always remain separated from the outer protective film when it does not need to contact it, providing a strong guarantee for the smooth progress of the entire packaging process.

[0018] In one optional embodiment, an adhesive piece is provided on the side of the first protective film away from the second protective film; the second packaging mechanism further includes a flipping assembly, which includes a flipping plate, a flipping gear, a second lifting assembly, an auxiliary block, a wedge rod, and a second elastic connector; the flipping plate is disposed between the first protective film and the corresponding limiting member, and is rotatably connected to the limiting member; the flipping gear is disposed on the side of the limiting member away from the first protective film, and is fixedly connected to the end of the flipping plate along the second direction; the second lifting assembly is fixed on the limiting member corresponding to the first protective film, and the lifting end of the second lifting assembly meshes with the flipping gear; the auxiliary block is fixed to the lifting end of the second lifting assembly, and its top surface... A sliding groove is provided, extending along a first direction; a slider is provided on the bottom surface of the wedge rod away from the second protective film along the first direction; the slider is engaged in the sliding groove and slidably connected to the sliding groove along the first direction; a second elastic connector is located on the side of the slider away from the second protective film, with its two ends connected to the inner wall of the slider and the sliding groove respectively; the moving mechanism includes a drive rod, which is fixed to the side of the gripper along the second direction; when the gripper descends, the drive rod abuts against the wedge-shaped surface at the top of the wedge rod, and the second elastic connector is in a contracted state; when the gripper rises, the second elastic connector is in an extended state, the drive rod abuts against the bottom surface of the wedge rod, and the lifting end of the second lifting assembly is in an elevated state.

[0019] By setting up a flip plate and an adhesive piece, when the gripper rises, the drive rod drives the lifting end of the second lifting assembly to rise, thereby driving the gear to rotate and flip the flip plate, so that the adhesive piece can be pasted with the second protective film, thus realizing the adhesive connection between the first and second protective films. This not only improves the automation level of packaging, but also significantly enhances the strength and reliability of the packaging.

[0020] In one optional embodiment, the inner protective bag is provided with an inflation port, and the inflation protection mechanism includes an air tube and a sealing bag; the air tube is provided with a conical head, which is located on the inflation end of the air tube, and the diameter of the conical head gradually decreases towards the side away from the air source; the sealing bag is fixedly connected to the position where the inflation port is located, and has an inflation position located inside the inner protective bag and a sealing position located outside the inner protective bag; when the air tube is connected to the inner protective bag, the sealing bag is in the inflation position, and the inflation end of the air tube passes through the inflation port and the sealing bag in sequence and is located inside the inner protective bag; when the air tube is separated from the inner protective bag, the conical head drives the sealing bag to move out of the inner protective bag, and the sealing bag is in the sealing position.

[0021] By using a conical head that works in conjunction with the sealing bag and the air tube, when the air tube is removed from the inflation port, the conical head moves the sealing bag along with it until the sealing bag completely covers and seals the inflation port, thus temporarily sealing the inflation port. This prevents external air or impurities from entering the inner protective bag, improving the reliability and safety of the packaging.

[0022] In one optional embodiment, the first packaging mechanism includes a receiving box and a sealing mechanism; the receiving box has a first opening and a second opening; the first opening is located at the top of the receiving box, and the inner protective bag passes through the first opening and is located inside the receiving box; the second opening is located on the side of the receiving box opposite to the second packaging mechanism, and the inflation end of the air tube passes through the second opening and the inflation port in sequence; the sealing mechanism is arranged adjacent to the receiving box for sealing the inner protective bag.

[0023] As the air tube moves along with the gripper when it picks up the second component and moves it onto the second packaging mechanism for packaging, by setting the second opening on the side of the receiving box away from the second packaging mechanism, interference between the air tube and the structure in the second packaging mechanism can be avoided when the gripper picks up the second component and moves it onto the second packaging mechanism for subsequent packaging. This not only improves the efficiency and reliability of packaging, but also reduces the risk of equipment damage. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] The following is combined Figures 1 to 5 The following describes embodiments of the present invention.

[0034] According to an embodiment of the present invention, in one aspect, a packaging device is provided, including a first packaging mechanism 1, an inflation protection mechanism, a moving mechanism, and a second packaging mechanism 4; the first packaging mechanism 1 includes an inner protective bag 11; the first packaging mechanism 1 is used to encapsulate the board to be packaged in the inner protective bag 11 to form a first component; the inflation protection mechanism is located upstream of the first packaging mechanism 1, adjacent to the first packaging mechanism 1, and connected to the inner protective bag 11, and is used to fill gas into the first component to form a second component, and to extract gas from the second component to form a third component; the moving mechanism is located adjacent to the first packaging mechanism 1 and is provided with a movable gripper 31; the second packaging mechanism 4 is located downstream of the first packaging mechanism 1, adjacent to the moving mechanism, and includes an outer protective film 41; the gripper 31 grasps the second component and places it on the second packaging mechanism 4, and the second packaging mechanism 4 is used to wrap the third component in the outer protective film 41.

[0035] The first packaging mechanism 1 encapsulates the board to be packaged in an inner protective bag 11, and the second packaging mechanism 4 wraps an outer protective film 41 around the inner protective bag 11, achieving double protection for the board. A moving mechanism transfers the second component to the second packaging mechanism 4. An inflation protection mechanism inflates the first component to form the second component. During the movement of the second component by the moving mechanism, the friction between the inner protective bag 11 and the board is significantly reduced, protecting the board's surface from damage. Furthermore, it effectively mitigates vibration and impact during movement, further enhancing the protective effect. Through the arrangement of the first packaging mechanism 1, the inflation protection mechanism, the moving mechanism, and the second packaging mechanism 4, automated packaging of the board is achieved, significantly reducing the labor intensity of workers and greatly improving packaging efficiency and final packaging quality.

[0036] In a specific embodiment, the moving mechanism includes a mounting frame 33, a linear module 34, and a lifting cylinder 35. The linear module 34 is fixed on the mounting frame 33. The lifting cylinder 35 is slidably disposed on the linear module 34 along the second direction. The gripper 31 is movably disposed on the lifting cylinder 35 along the vertical direction. The gripper 31 extends along the second direction and is used to clamp the heat seal of the second component.

[0037] Specifically, gripper 31 is a pneumatic gripper.

[0038] Specifically, the inner protective bag 11 is an aluminum foil bag; the outer protective film 41 is a blister film.

[0039] Specifically, the board to be packaged is a printed circuit board assembly.

[0040] In one embodiment, the second packaging mechanism 4 further includes a limiting component, which includes a driving mechanism and two limiting members 422. The two limiting members 422 are arranged opposite to each other and spaced apart along a first direction. The driving mechanism is tractively connected to both limiting members 422. Under the drive of the driving mechanism, the two limiting members 422 have a first position away from each other and a second position close to each other. The second packaging mechanism 4 and the first packaging mechanism 1 are arranged sequentially along a second direction. The outer protective film 41 includes a first protective film 411 and a second protective film 412 connected to each other. The connection between the first protective film 411 and the second protective film 412 is located between the two limiting members 422. When the limiting member 422 is in the first position, the first protective film 411 and the second protective film 412 are both arranged parallel to the first direction and are respectively located on the top of the two limiting members 422. When the limiting member 422 is in the second position, the first protective film 411 and the second protective film 412 are located between the two limiting members 422 and are both arranged perpendicular to the first direction. The first direction is perpendicular to the second direction.

[0041] By setting two limiting members 422, the outer protective film 41 can be supported and limited. When the limiting members 422 are in the first position, the first protective film 411 and the second protective film 412 are respectively located on top of the two limiting members 422. The two limiting members 422 can support the first protective film 411 and the second protective film 412, and the moving mechanism can place the second component between the first protective film 411 and the second protective film 412 to prepare for the subsequent packaging steps. During the process of the limiting members 422 moving to the second position, the connection between the first protective film 411 and the second protective film 412 descends together with the third component. The ends of the first protective film 411 and the second protective film 412 away from the connection gradually approach each other and gradually wrap around the two sides of the third component along the first direction, reducing the friction between the outer protective film 41 and the inner protective bag 11.

[0042] In one embodiment, a control system is also included, which is communicatively connected to the moving mechanism; the limiting component further includes a placement plate 423 and a first pressure sensor 424; the placement plate 423 is fixed to one side of the bottom of the limiting member 422, and both limiting members 422 are slidably connected to the placement plate 423; the first pressure sensor 424 is located between the two limiting members 422, fixed on the placement plate 423, and communicatively connected to the control system; when the two limiting members 422 approach each other, the control system controls the gripper 31 to grip the third component and move it toward the side closer to the placement plate 423; when the pressure between the outer protective film 41 and the first pressure sensor 424 reaches a set value, the control system controls the gripper 31 to move toward the side away from the placement plate 423.

[0043] By setting the placement plate 423, when the two limiting members 422 are in the second position and the first protective film 411 and the second protective film 412 are located between the two limiting members 422, the placement plate 423 can support and limit the first protective film 411 and the second protective film 412, which helps to support and fix the outer protective film 41, prevent the first protective film 411 and the second protective film 412 from falling off, and realize the stable placement of the third component between the first protective film 411 and the second protective film 412. Furthermore, by setting the first pressure sensor 424 on the placement plate 423, when the pressure between the outer protective film 41 and the first pressure sensor 424 reaches the set value, the control system controls the gripper 31 to move away from the placement plate 423, preventing the gripper 31 from continuing to push the third component closer to the placement plate 423, thereby effectively avoiding damage to the packaging board in the third component due to excessive squeezing. By setting the control system, the placement plate 423 and the first pressure sensor 424, not only is the stability of the packaging enhanced, but the automation level and safety of the entire packaging process are also significantly improved.

[0044] In a specific embodiment, the conveyor belt 5 extends along a second direction; the second packaging mechanism 4 includes a support frame 46, which includes two support side plates 461 and a support plate 462. The two support side plates 461 are located on both sides of the conveyor belt 5 along a first direction, and the support plate 462 is located above the conveyor belt 5, with both ends fixedly connected to the two support side plates 461. Two limiting members 422 are fixed on the support plate 462; the placement plate 423 is located above the support plate 462, with one end connected to the support plate 462 via a set of fixing rods 463, and the other end passing through the two limiting members 422 in sequence and connected to the support plate 462 via another set of fixing rods 463.

[0045] In a specific embodiment, the driving mechanism includes a rotary motor 4211, a bidirectional lead screw 4212, and two limiting rods 4213. The bidirectional lead screw 4212 and the two limiting rods 4213 are both located between the placement plate 423 and the support plate 462. The rotary motor 4211 is fixed on a support side plate 461. One end of the bidirectional lead screw 4212 is connected to the driving end of the rotary motor 4211, and the other end passes through two limiting members 422 in sequence and is rotatably connected to another support side plate 461. The bidirectional lead screw 4212 is threadedly connected to both limiting members 422. The two limiting rods 4213 are located on both sides of the bidirectional lead screw 4212 along the second direction. One end of the limiting rod 4213 is connected to one support side plate 461, and the other end passes through two limiting members 422 in sequence and is connected to another support side plate 461.

[0046] In one embodiment, the system further includes a control system, which is communicatively connected to the drive mechanism; the limiting component also includes two second pressure sensors 425, which are respectively disposed on the side of the two limiting members 422 that are close to each other, and both are communicatively connected to the control system; when the pressure between the second pressure sensor 425 and the outer protective membrane 41 reaches a set value, the control system controls the drive mechanism to stop driving.

[0047] When the two limiting members 422 are close to each other in the second position, the third component and the outer protective film 41 are both located between the two limiting members 422. By setting two pressure sensors on the side where the two limiting members 422 are close to each other, when the pressure between the second pressure sensor 425 and the outer protective film 41 reaches the set value, the control system controls the drive mechanism to stop driving, preventing the two limiting members 422 from continuing to approach each other and squeezing the third component, avoiding possible squeezing damage to the packaging board, and ensuring the product yield. By setting the second pressure sensor 425, not only is the accuracy of packaging improved, but the safety and reliability of the entire packaging process are also significantly enhanced.

[0048] In one embodiment, the second packaging mechanism 4 further includes two sets of limiting rollers 43, which are movably disposed above the two limiting members 422. When the limiting member 422 is in the first position, the limiting roller 43 abuts against the top of the outer protective film 41. When the limiting member 422 moves from the first position to the first position, the limiting roller 43 rotates away from the outer protective film 41.

[0049] By setting the limiting roller 43, when the limiting member 422 is in the first position, the limiting roller 43 abuts against the top of the outer protective film 41, which not only enhances the stability of the outer protective film 41, but also effectively prevents the outer protective film 41 from accidentally detaching from the limiting member 422 through its synergistic effect with the limiting member 422, thereby ensuring the accuracy and reliability of the packaging; when the limiting member 422 moves from the first position to the second position, the limiting roller 43 rotates to the side away from the outer protective film 41, avoiding the limiting roller 43 from obstructing the rotation of the first protective film 411 or the second protective film 412 to the position between the two limiting members 422; by setting the limiting roller 43, not only is the automation level of packaging improved, but the stability and smoothness of the entire packaging process are also ensured.

[0050] In one embodiment, the second packaging mechanism 4 further includes a swing assembly 44, which includes a swing shaft, a swing gear 441, and a first lifting assembly 442. The swing shaft is disposed adjacent to the outer protective film 41 along a second direction, rotatably disposed on top of the limiting member 422, and extends along a first direction. The limiting roller 43 is rotatably connected to the swing shaft and disposed perpendicular to the swing shaft. The swing gear 441 is sleeved on the outer periphery of the swing shaft and fixedly connected to the swing gear 441. The first lifting assembly 442 is disposed on the side of the swing shaft away from the outer protective film 41, and the lifting end of the first lifting assembly 442 meshes with the swing gear 441. The moving mechanism includes a drive rod 32, which is fixed to the side of the gripper 31 along the second direction. When the gripper 31 descends, the drive rod 32 drives the lifting end of the first lifting assembly 442 to descend, and the limiting roller 43 rotates away from the outer protective film 41.

[0051] By setting the swing assembly 44, the rotation of the limiting roller 43 to the side away from the outer protective film 41 is achieved; when the lifting end of the first lifting assembly 442 descends and drives the swing gear 441 to rotate, the swing shaft rotates synchronously. Since the limiting roller 43 is set perpendicular to the swing shaft, as the swing shaft rotates, the limiting roller 43 will rotate to the side away from the outer protective film 41 along with the swing shaft.

[0052] In a specific embodiment, the limiting member 422 includes a limiting plate 4221 and two limiting side plates 4222. An outer protective film 41 is disposed on the top of the limiting plate 4221. The two limiting side plates 4222 are respectively disposed on both sides of the limiting plate 4221 along the second direction. A swing support 443 is provided on the top of the limiting side plate 4222, and a swing shaft is rotatably connected to the swing support 443.

[0053] Specifically, a transition block is provided on the swing shaft, and the limiting roller 43 is rotatably connected to the transition block.

[0054] In a specific implementation, each limiting plate 4221 is provided with limiting rollers 43 on both sides along the second direction; each limiting roller 43 is provided with a set of swing components 44.

[0055] In a specific implementation, in the second direction, the length of the gripper 31 is greater than the distance between the two limiting side plates 4222; in the first direction, the length of the drive rod 32 is greater than the distance between the two sets of first lifting components 442; when the gripper 31 descends, the drive rod 32 contacts the lifting block 4422 and presses the lifting block 4422 downward.

[0056] In one embodiment, the first lifting assembly 442 includes a fixed block 4421, a lifting block 4422, a first elastic connector 4423, and a magnetic component 4424; the fixed block 4421 is fixed to the limiting component 422; the lifting block 4422 is located above the fixed block 4421 and meshes with the swing gear 441; the first elastic connector 4423 is connected between the fixed block 4421 and the lifting block 4422; when the limiting roller 43 abuts against the top of the outer protective film 41, the first elastic connector 4423 is in an extended state; when the limiting roller 43 rotates away from the outer protective film 41, the first elastic connector 4423 is in a retracted state; the magnetic component 4424 is fixed to the bottom of the lifting block 4422 for magnetic connection with the top of the fixed block 4421.

[0057] Because a first elastic connector 4423 is connected between the fixed block 4421 and the lifting block 4422, and the first elastic connector 4423 is in an extended state when the limiting roller 43 abuts against the top of the outer protective film 41, the first elastic connector 4423 can support the lifting block 4422, ensuring that the limiting roller 43 is in contact with the outer protective film 41; when the limiting roller 43 rotates away from the outer protective film 41, the lifting block 4422 descends and compresses the first elastic connector 4423, and drives the limiting roller 43 to rotate away from the outer protective film 41; by setting a magnetic component 4424 When the lifting block 4422 descends to abut against the fixed block 4421, the magnetic component 4424 can fix the lifting block 4422, ensuring that the limiting roller 43 is always separated from the outer protective film 41 during the subsequent packaging process. The arrangement of the fixed block 4421, the lifting block 4422, the first elastic connector 4423 and the magnetic component 4424 not only enhances the stability of the system, but also ensures that the limiting roller 43 can always remain separated from the outer protective film 41 when it does not need to contact the outer protective film 41, providing a strong guarantee for the smooth progress of the entire packaging process.

[0058] In a specific embodiment, the lifting block 4422 has a first tooth surface on the side near the swing gear 441. The swing gear 441 meshes with the first tooth surface. When the lifting block 4422 descends, the first tooth surface drives the swing gear 441 to rotate, thereby controlling the height of the lifting block 4422 and the number of rotating teeth of the swing gear 441. When the limiting roller 43 rotates to the vertical state, the lifting block 4422 descends below the swing base to avoid obstructing the swing of the limiting roller 43. Specifically, the rotation angle of the limiting roller 43 is greater than ninety degrees.

[0059] In a specific embodiment, the fixing block 4421 is fixed on the limiting side plate 4222, and the top of the fixing block 4421 is provided with a guide rod 4425, which extends in the vertical direction; the lifting block 4422 is provided with a guide through hole, through which the guide rod 4425 passes.

[0060] In a specific implementation, in its natural state, the first elastic connector 4423 is in an extended state, which lifts the lifting block 4422 upward.

[0061] Specifically, the first elastic connector 4423 is a support spring.

[0062] Specifically, the magnetic component 4424 is a magnetic sheet; an iron block 4426 is provided on the top of the fixing block 4421; the iron block 4426 and the magnetic sheet are used together, and when the lifting block 4422 descends to the point where the iron block 4426 and the magnetic sheet attract each other, the limiting roller 43 is kept separated from the outer protective film 41.

[0063] In one embodiment, an adhesive member 413 is provided on the side of the first protective film 411 away from the second protective film 412; the second packaging mechanism 4 further includes a flipping assembly 45, which includes a flipping plate 451, a flipping gear 452, a second lifting assembly 453, an auxiliary block 454, a wedge rod 455, and a second elastic connector 456; the flipping plate 451 is disposed between the first protective film 411 and the corresponding limiting member 422, and is rotatably connected to the limiting member 422; the flipping gear 452 is disposed on the side of the limiting member 422 away from the first protective film 411, and is fixedly connected to the end of the flipping plate 451 along the second direction; the second lifting assembly 453 is fixed on the limiting member 422 corresponding to the first protective film 411, and the lifting end of the second lifting assembly 453 meshes with the flipping gear 452; the auxiliary block 454 is fixed to the lifting end of the second lifting assembly 453, and has a top surface with A sliding groove 4541 extends along a first direction; a slider 4551 is provided on the side of the bottom surface of the wedge rod 455 away from the second protective film 412 along the first direction; the slider 4551 is engaged in the sliding groove 4541 and is slidably connected to the sliding groove 4541 along the first direction; a second elastic connector 456 is located on the side of the slider 4551 away from the second protective film 412, and its two ends are respectively connected to the inner wall of the slider 4551 and the sliding groove 4541; the moving mechanism includes a drive rod 32, which is fixed to the side of the gripper 31 along the second direction; when the gripper 31 descends, the drive rod 32 abuts against the wedge-shaped surface at the top of the wedge rod 455, and the second elastic connector 456 is in a contracted state; when the gripper 31 rises, the second elastic connector 456 is in an extended state, the drive rod 32 abuts against the bottom surface of the wedge rod 455, and the lifting end of the second lifting assembly 453 is in a raised state.

[0064] By setting up a flip plate 451 and an adhesive piece 413, when the gripper 31 rises, the drive rod 32 drives the lifting end of the second lifting assembly 453 to rise, thereby driving the gear to rotate and flip the flip plate 451, so that the adhesive piece 413 can be pasted with the second protective film 412, thereby realizing the adhesive connection between the first protective film 411 and the second protective film 412. This not only improves the automation level of packaging, but also significantly enhances the firmness and reliability of the packaging.

[0065] In a specific implementation, the flip plate 451 is provided with flip shafts on both sides along the second direction, and the flip shafts are provided through the limiting side plate 4222; the two flip shafts are respectively connected to two flip gears 452, and the two flip gears 452 are connected to two sets of second lifting components 453; each set of second lifting components 453 is respectively connected to an auxiliary block 454, a wedge rod 455 and a second elastic connector 456.

[0066] In a specific embodiment, the second lifting assembly 453 includes a lifting base 4531 and a lifting rod 4532; the lifting base 4531 is fixed on the limiting side plate 4222, and a lifting groove is provided on the top surface of the lifting base 4531; the lifting rod 4532 is slidably disposed in the lifting groove; a second tooth surface is provided on the side of the lifting rod 4532, and the flip gear 452 meshes with the second tooth surface; in the natural state, the bottom of the lifting rod 4532 abuts against the bottom wall of the lifting groove, and the second elastic connector 456 is in an extended state.

[0067] Specifically, the second elastic connector 456 is a telescopic spring.

[0068] In a specific implementation, when the gripper 31 descends, it drives the drive rod 32 to descend until it abuts against the wedge surface of the wedge rod 455, and pushes the wedge rod 455 away from the first lifting assembly 442. After the drive rod 32 descends past the wedge rod 455, the second elastic connector 456 returns to its extended state, pushing the wedge rod 455 back to its original position. When the gripper 31 rises, it drives the drive rod 32 to rise, and the drive rod 32 abuts against the bottom surface of the wedge rod 455, driving the wedge rod 455 to rise synchronously. The wedge rod 455 drives the lifting rod 4532 to rise synchronously, thereby driving the flipping gear 452 to rotate, and finally causing the flipping plate 451 to flip. When the flipping plate 451 flips to a vertical state, the gripper 31 has risen above the flipping plate 451. Then the gripper 31 continues to rise, causing the flipping plate 451 to continue to flip until the adhesive 413 is adhered to the second protective film 412.

[0069] In a specific implementation, the adhesive 413 is double-sided tape.

[0070] In a specific implementation, the height of the limiting member 422 corresponding to the flipping component 45 is higher than the height of the limiting member 422 corresponding to the second protective film 412.

[0071] In a specific embodiment, the length of the first protective film 411 is greater than the length of the second protective film 412; when the first protective film 411 and the second protective film 412 are located between the two limiting members 422, the part of the first protective film 411 with the adhesive member 413 can be attached to the second protective film 412 under the action of the flip plate 451.

[0072] In a specific implementation, after the worker places the outer protective film 41 above the limiting member 422, one side of the adhesive member 413 is attached to the first protective film 411, and the other side of the adhesive member 413 is peeled off so that it can be attached to the second protective film 412.

[0073] In a specific implementation, both the slider 4551 and the groove 4541 are T-shaped.

[0074] In one embodiment, the inner protective bag 11 is provided with an inflation port 12, and the inflation protection mechanism includes an air tube 21 and a sealing bag 23. The air tube 21 is provided with a conical head 22, which is located on the inflation end of the air tube 21, and the diameter of the conical head 22 gradually decreases towards the side away from the air source. The sealing bag 23 is fixedly connected to the position where the inflation port 12 is located, and has an inflation position located inside the inner protective bag 11 and a sealing position located outside the inner protective bag 11. When the air tube 21 is connected to the inner protective bag 11, the sealing bag 23 is in the inflation position, and the inflation end of the air tube 21 passes through the inflation port 12 and the sealing bag 23 in sequence and is located inside the inner protective bag 11. When the air tube 21 is separated from the inner protective bag 11, the conical head 22 drives the sealing bag 23 to move out of the inner protective bag 11, and the sealing bag 23 is in the sealing position.

[0075] By setting the sealing bag 23 to cooperate with the conical head 22 of the air tube 21, when the air tube 21 is pulled off the inflation port 12, the conical head 22 will drive the sealing bag 23 to move together until the sealing bag 23 completely covers and seals the position of the inflation port 12, thereby achieving a temporary seal on the inflation port 12. This can prevent external air or impurities from entering the inner protective bag 11, thus improving the reliability and safety of the packaging.

[0076] In a specific embodiment, the conical head 22 includes a conical tip 221 and a conical ring 222 arranged sequentially. The conical tip 221, along with the conical ring 222, passes through the inflation port 12 and the sealing bag 23 in sequence. When the air tube 21 is pulled out, the side of the conical ring 222 that faces away from the conical tip 221 with a larger diameter brings the sealing bag 23 to the outside of the inflation port 12, thereby blocking the inflation port 12 to achieve a temporary seal.

[0077] In a specific embodiment, the inflation protection mechanism includes a nitrogen source 24, an inflation pump 25, a vacuum pump 26, a first solenoid valve 27, and a second solenoid valve 28; the air pipe 21 includes a main pipe 211, a first branch pipe 212, and a second branch pipe 213; the inflation end of the main pipe 211 is connected to the inner protective bag 11, and the other end is connected to the first branch pipe 212 and the second branch pipe 213; the other ends of the first branch pipe 212 and the second branch pipe 213 are both connected to the nitrogen source 24; the first solenoid valve 27 and the inflation pump 25 are disposed on the first branch pipe 212, and the first solenoid valve 27 controls the opening and closing of the first branch pipe 212; the second solenoid valve 28 and the vacuum pump 26 are disposed on the second branch pipe 213, and the second solenoid valve 28 controls the opening and closing of the second branch pipe 213.

[0078] In a specific implementation, the first solenoid valve 27 and the air pump 25 are opened, while the second solenoid valve 28 and the vacuum pump 26 are both closed, filling the first component with nitrogen to form the second component; after the nitrogen is filled, the first solenoid valve 27 and the air pump 25 are both closed. The second solenoid valve 28 and the vacuum pump 26 are then opened, while the first solenoid valve 27 and the air pump 25 are both closed, evacuating the second component to form the third component; after the vacuum is evacuated, the control system detects the air pressure in the gas pipe 21 to control the closure of the vacuum pump 26.

[0079] In one embodiment, the first packaging mechanism 1 includes a receiving box 13 and a sealing mechanism 14; the receiving box 13 has a first opening and a second opening; the first opening is located at the top of the receiving box 13, and the inner protective bag 11 passes through the first opening and is located inside the receiving box 13; the second opening is located on the side of the receiving box 13 opposite to the second packaging mechanism 4, and the inflation end of the air tube 21 passes through the second opening and the inflation port 12 in sequence; the sealing mechanism 14 is arranged adjacent to the receiving box 13 and is used to seal the inner protective bag 11.

[0080] As the air pipe 21 moves along with the gripper 31 when it grabs the second component and moves it onto the second packaging mechanism 4 for packaging, by setting the second opening on the side of the receiving box 13 away from the second packaging mechanism 4, when the gripper 31 grabs the second component and moves it onto the second packaging mechanism 4 for subsequent packaging, interference between the air pipe 21 and the structure in the second packaging mechanism 4 can be avoided. This not only improves the efficiency and reliability of packaging, but also reduces the risk of equipment damage.

[0081] In a specific implementation, the first opening is connected to the second opening, and when the inner protective bag 11 is placed into the receiving box 13, it helps the trachea 21 to enter the second opening.

[0082] Specifically, the second opening extends vertically, which helps the trachea 21 slide within the second opening.

[0083] Specifically, sealing mechanism 14 is a heat sealing machine.

[0084] Preferably, the container 13 is equipped with a position sensor, and the position sensor is communicatively connected to the control system. When the container 13 moves to the position of the moving mechanism under the conveyor belt 5, the position sensor and the moving mechanism sense each other and send a signal to the control system. The control system controls the conveyor belt 5 to stop transporting to ensure that the container 13 remains stationary during the gripping process. At the same time, the control system controls the gripper 31 of the moving mechanism to move to the position of the container 13 and grip the second component. Throughout the process, the position sensor, the control system, and the moving mechanism work closely together, and the gripper 31 can accurately position and grip the second component, thereby ensuring the accuracy and efficiency of the gripping.

[0085] In a specific implementation, the receiving box 13 is placed on the conveyor belt 5, corresponding to the position of the sealing mechanism 14; the worker places the board to be packaged into the inner protective bag 11, inserts the air tube 21 into the inflation port 12 on the side of the inner protective bag 11, and then places the inner protective bag 11 into the receiving box 13, and the heat sealing machine seals the inner protective bag 11 to form the first component; then the inflation protection mechanism inflates the inner protective bag 11 to form the second component; the moving mechanism picks up the position of the second component that has been heat-sealed and moves it above the outer protective film 41, and then the lifting cylinder 35 drives... The second component descends, and simultaneously the second solenoid valve 28 and vacuum pump 26 open to evacuate the second component, forming the third component. After evacuation is complete, vacuum pump 26 closes, and the control system controls the rotation motor 4211 to open. The two limiting members 422 slide towards each other, and the connection between the first protective film 411 and the second protective film 412 descends along with the third component, gradually wrapping around both sides of the third component along the first direction. When the second pressure sensor 425 detects that the pressure between the limiting member 422 and the outer protective film 41 has reached a set value, the rotation motor 4211 stops. The rotation stops, and the two limit plates 4221 stop moving. During the descent of the gripper 31, the drive rod 32 drives the swing assembly 44 to rotate the limit roller 43 away from the outer protective film 41. When the gripper 31 descends to the point where the third assembly is about to contact the first pressure sensor 424, the limit roller 43 rotates to a position that does not obstruct the flipping plate 451 from flipping. The lifting cylinder 35 drives the third assembly to descend until the pressure between the outer protective film 41 and the first pressure sensor 424 reaches the set value. At this point, the gripper 31 stops descending, then releases the third assembly and begins to rise. During the process, the drive rod 32 drives the flipping assembly 45 to flip the flipping plate 451, so that the adhesive piece 413 is attached to the second protective film 412; then the drive motor 4211 is driven to separate the two limiting plates 4221, and the staff takes out the packaged components and removes the air tube 21. The air inlet 12 has a sealing bag 23 to temporarily and quickly seal the air inlet 12 to prevent air leakage. Then the staff attaches a sealing sticker to the air inlet 12, and then bends the part of the outer protective film 41 that is attached to the air inlet 12 to one side. Finally, it is put into the packaging box to complete the packaging.

[0086] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
