Description

Technical Field

[0001] The present invention relates to the technical field of packaging, in particular to packaging equipment. Background Art

[0002] Currently, the packaging process of printed circuit board assemblies (PCBA boards) mainly relies on manual operation. Workers need to perform repetitive and tedious manual operations for a long time, which increases the labor intensity of workers and easily causes fatigue and reduced efficiency. At the same time, under long-term operation, the accuracy of the operation is difficult to maintain at a high level for a long time, affecting the overall quality and efficiency of the packaging. And because it is difficult to completely avoid physical contact with the product during manual handling, the risk of damage to the printed circuit board assembly 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] The present invention provides a packaging device, comprising a first packaging mechanism, an inflation protection mechanism, a moving mechanism and a second packaging mechanism; the first packaging mechanism comprises an inner protection bag; the first packaging mechanism is used to encapsulate a plate to be packaged in the inner protection bag to form a first component; the inflation protection mechanism is arranged adjacent to the first packaging mechanism and connected to the inner protection bag, and is used to fill gas into the first component to form a second component, and to extract the gas in the second component to form a third component; the moving mechanism is arranged adjacent to the first packaging mechanism and is provided with a movable clamp; the second packaging mechanism is located downstream of the first packaging mechanism, is arranged adjacent to the moving mechanism, and comprises an outer protective film; the clamp grabs the second component and places it on the second packaging mechanism, and the second packaging mechanism is used to wrap the third component in the outer protective film.

[0005] The first packaging mechanism is used to encapsulate the board to be packaged in the inner protective bag, and the second packaging mechanism is used to wrap the outer protective film on the outside of the inner protective bag, thereby achieving double protection for the board to be packaged; the moving mechanism is used to transfer the second component to the second packaging mechanism; the inflatable protection mechanism is used to inflate the first component to form the second component, so that in the process of the moving mechanism grabbing the second component and moving it to the second packaging mechanism, not only can the friction between the inner protective bag and the board to be packaged be significantly reduced, thereby protecting the surface of the board to be packaged from damage, but also the vibration and collision suffered by the board to be packaged during the movement can be effectively alleviated, further improving the protection effect. Through the setting of the first packaging mechanism, the inflatable protection mechanism, the moving mechanism and the second packaging mechanism, the automatic packaging of the board to be packaged is achieved, which not only greatly reduces the labor intensity of the staff, but also significantly improves the packaging efficiency and final packaging quality of the board to be packaged.

[0006] In an optional embodiment, the second packaging mechanism also includes a limiting assembly, the limiting assembly 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 transmission-connected to the two limiting members, and under the drive of the driving mechanism, the two limiting members have a first position away from each other, and a second position close to each other; the second packaging mechanism and the first packaging mechanism are arranged in sequence along the second direction; the outer protective film includes a first protective film and a second protective film connected to each other, and 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 limit members, the outer protective film can be supported and limited; when the limit members are in the first position, the first protective film and the second protective film are respectively located on the top of the two limit members, the two limit members can support the first protective film and the second protective film, and the moving mechanism can place the second component between the first protective film and the second protective film, preparing for the subsequent packaging steps; in the process of the limit members moving to the second position, the connection between the first protective film and the second protective film descends together with the third component, and the ends of the first protective film and the second protective film away from the connection gradually approach each other, gradually wrapping the two sides of the third component along the first direction, reducing the friction between the outer protective film and the inner protective bag.

[0008] In an optional embodiment, it also includes a control system, which is communicatively connected to the moving mechanism; the limiting component also includes a placement plate and a first pressure sensor; the placement plate is fixed to one side of the bottom of the limiting component, and the two limiting components are slidably connected to the placement plate; the first pressure sensor is located between the two limiting components, fixed to the placement plate, and communicatively connected to the control system; when the two limiting components approach each other, the control system controls the clamping jaw to clamp the third component and move to the side close 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 clamping jaw to move to the side away from the placement plate.

[0009] By setting a placement plate, when the two limit members are in the second position and the first protective film and the second protective film are located between the two limit members, the placement plate can support and limit the first protective film and the second protective film, which is helpful to support and fix the outer protective film and prevent the first protective film and the second protective film from falling, thereby achieving the third component being firmly placed between the first protective film and the second protective film; and 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 clamp to move to the side away from the placement plate to prevent the clamp from continuing to push the third component toward the placement plate, thereby effectively avoiding damage to the board to be packaged in the third component due to excessive extrusion; by setting the control system, the placement plate and the first pressure sensor, not only the stability of the packaging is enhanced, but also the automation level and safety of the entire packaging process are significantly improved.

[0010] In an optional embodiment, it also includes a control system, which is communicatively connected to the driving mechanism; the limit assembly also includes two second pressure sensors, which are respectively arranged on the side where the two limit members are close to each other, and are both communicatively connected to the control system; when the pressure between the second pressure sensor and the outer protective film reaches a set value, the control system controls the driving mechanism to stop driving.

[0011] Because when the two limit members are close to each other and in the second position, the third component and the outer protective film are both located between the two limit members, and two pressure sensors are respectively arranged on the side where the two limit members are close to each other, when the pressure between the second pressure sensor and the outer protective film reaches the set value, the control system controls the driving mechanism to stop driving to prevent the two limit members from continuing to approach each other and squeezing the third component, thereby avoiding possible squeezing damage to the board to be packaged and ensuring the yield rate of the product; by arranging the second pressure sensor, not only the accuracy of the packaging is improved, but also the safety and reliability of the entire packaging process are significantly enhanced.

[0012] In an optional embodiment, the second packaging mechanism also includes two groups of limiting rollers, which are movably arranged above the two limiting members, respectively. 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 second position, the limiting rollers rotate to the side away from the outer protective film.

[0013] By setting a limiting roller, when the limiting member is in the first position, the limiting roller abuts against the top of the outer protective film, which not only enhances the stability of the outer protective film, but also effectively prevents the outer protective film from accidentally detaching from the limiting member through the coordinated effect with the limiting member, thereby ensuring the accuracy and reliability of the packaging; when the limiting member moves from the first position to the second position, the limiting roller rotates to the side away from the outer protective film, avoiding the limiting roller from obstructing the first protective film or the second protective film in the process of rotating to the position between the two limiting members; by setting the limiting roller, not only the degree of automation of the packaging is improved, but also the stability and smoothness of the entire packaging process are ensured.

[0014] In an optional embodiment, the second packaging mechanism also includes a swinging assembly, which includes a swinging shaft, a swinging gear and a first lifting assembly; the swinging shaft is arranged adjacent to the outer protective film along the second direction, is rotatably arranged on the top of the limit member, and extends along the first direction; the limit roller is rotatably connected to the swinging shaft and is arranged perpendicular to the swinging shaft; the swinging gear is sleeved on the outer periphery of the swinging shaft and fixedly connected to the swinging gear; the first lifting assembly is arranged on the side of the swinging shaft away from the outer protective film, and the lifting end of the first lifting assembly is meshed with the swinging gear; the moving mechanism includes a driving rod, which is fixed to the side of the clamp along the second direction; when the clamp descends, the driving rod drives the lifting end of the first lifting assembly to descend, and the limiting roller rotates to the side away from the outer protective film.

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

[0016] In an optional embodiment, the first lifting assembly includes a fixed block, a lifting block, a first elastic connecting member and a magnetic member; the fixed block is fixed on the limiting member; the lifting block is located above the fixed block and meshes with the swing gear; the first elastic connecting member 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 connecting member is in an extended state; when the limiting roller rotates to the side away from the outer protective film, the first elastic connecting member is in a contracted state; the magnetic member is fixed to the bottom of the lifting block for magnetic connection with the top of the fixed block.

[0017] Since a first elastic connecting member is connected between the fixed block and the lifting block, and when the limiting roller abuts against the top of the outer protective film, the first elastic connecting member is in an extended state, the first elastic connecting member can support the lifting block, ensuring that the limiting roller is in an abutting state with the outer protective film; when the limiting roller rotates to the side away from the outer protective film, the lifting block descends and compresses the first elastic connecting member, and drives the limiting roller to rotate to the side away from the outer protective film; by setting a magnetic member, when the lifting block descends to abut against the fixed block, the magnetic member can fix the lifting block, ensuring that the limiting roller is always in a separated state from the outer protective film during the subsequent packaging of the outer protective film; through the setting of the fixed block, the lifting block, the first elastic connecting member and the magnetic member, not only the stability of the system is enhanced, but also it is ensured that the limiting roller can always remain in a position separated from the outer protective film when it does not need to contact the outer protective film, providing a strong guarantee for the smooth progress of the entire packaging process.

[0018] In an optional embodiment, a sticking piece is provided on the side of the first protective film away from the second protective film; the second packaging mechanism also includes a flip assembly, which includes a flip plate, a flip gear, a second lifting assembly, an auxiliary block, a wedge rod and a second elastic connecting piece; the flip plate is arranged between the first protective film and the corresponding limiter, and is rotatably connected to the limiter; the flip gear is arranged on the side of the limiter away from the first protective film, and is fixedly connected to the end of the flip plate along the second direction; the second lifting assembly is fixed on the limiter corresponding to the first protective film, and the lifting end of the second lifting assembly is meshed with the flip gear; the auxiliary block is fixed to the lifting end of the second lifting assembly, and the top surface A slide groove is provided, which extends along the first direction; a slider is provided on the side of the bottom surface of the wedge rod away from the second protective film along the first direction; the slider is clamped in the slide groove and slidably connected with the slide groove along the first direction; the second elastic connecting member is located on the side of the slider away from the second protective film, and the two ends are respectively connected to the slider and the inner wall of the slide groove; the moving mechanism includes a driving rod, which is fixed to the side of the clamping jaw along the second direction; when the clamping jaw descends, the driving rod abuts against the wedge surface at the top of the wedge rod, and the second elastic connecting member is in a contracted state; when the clamping jaw rises, the second elastic connecting member is in an extended state, the driving rod abuts against the bottom surface of the wedge rod, and the lifting end of the second lifting assembly is in an ascending state.

[0019] By setting a flip plate and an adhesive, when the clamp rises, the driving 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 can be adhered to the second protective film, thereby realizing the adhesive connection between the first protective film and the second protective film, which not only improves the degree of automation of packaging, but also significantly enhances the firmness and reliability of packaging.

[0020] In an optional embodiment, an inflation port is provided on the inner protective bag, and the inflation protection mechanism includes an air pipe and a sealing bag; the air pipe is provided with a conical head, which is arranged on the inflation end of the air pipe, and the diameter of the conical head gradually decreases toward 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 pipe is connected to the inner protective bag, the sealing bag is in the inflation position, and the inflation end of the air pipe passes through the inflation port and the sealing bag in turn and is located inside the inner protective bag; when the air pipe 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 setting the sealing bag to cooperate with the conical head of the air tube, when the air tube is pulled out from the inflation port, as the air tube is detached, the conical head will drive the sealing bag to move together until the sealing bag completely covers and seals the location of the inflation port, thereby achieving a temporary seal of the inflation port, preventing external air or impurities from entering the inner protective bag, and improving the reliability and safety of the packaging.

[0022] In an optional embodiment, the first packaging mechanism includes a containing box and a sealing mechanism; the containing box is provided with a first opening and a second opening; the first opening is arranged at the top of the containing box, and the inner protective bag passes through the first opening and is located in the containing box; the second opening is arranged on the side of the containing box away from 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 containing box, and is used to seal the inner protective bag.

[0023] When the gripper grabs the second component and moves it to the second packaging mechanism for packaging, the air tube will move with it. By setting the second opening on the side of the containing box away from the second packaging mechanism, when the gripper grabs the second component and moves it to the second packaging mechanism for subsequent packaging, interference between the air tube and the structure in the second packaging mechanism can be avoided, which not only improves the efficiency and reliability of packaging, but also reduces the risk of equipment damage.

[0033] Combine the following Figures 1 to 5 , describing an embodiment of the present invention.

[0034] According to an embodiment of the present invention, on the one hand, 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 to-be-packaged board in the inner protective bag 11 to form a first component; the inflation protection mechanism is located upstream of the first packaging mechanism 1, is arranged adjacent to the first packaging mechanism 1, and is 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 the gas in the second component to form a third component; the moving mechanism is arranged adjacent to the first packaging mechanism 1, and is provided with a movable clamp 31; the second packaging mechanism 4 is located downstream of the first packaging mechanism 1, is arranged adjacent to the moving mechanism, and includes an outer protective film 41; the clamp 31 grabs 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 is used to encapsulate the board to be packaged in the inner protective bag 11, and the second packaging mechanism 4 is used to wrap the outer protective film 41 on the outside of the inner protective bag 11, thereby achieving double protection for the board to be packaged; the moving mechanism is used to transfer the second component to the second packaging mechanism 4; the inflatable protection mechanism is used to inflate the first component to form the second component, so that in the process of the moving mechanism grabbing the second component and moving it to the second packaging mechanism 4, not only can the friction between the inner protective bag 11 and the board to be packaged be significantly reduced, thereby protecting the surface of the board to be packaged from damage, but also the vibration and collision suffered by the board to be packaged during the movement can be effectively alleviated, further improving the protection effect. Through the setting of the first packaging mechanism 1, the inflatable protection mechanism, the moving mechanism and the second packaging mechanism 4, the automatic packaging of the board to be packaged is achieved, which not only greatly reduces the labor intensity of the staff, but also significantly improves the packaging efficiency and final packaging quality of the board to be packaged.

[0038] Specifically, the inner protective bag 11 is an aluminum foil bag; and 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 also includes a limiting assembly, which includes a driving mechanism and two limiting members 422, and the two limiting members 422 are arranged opposite to each other and at intervals along the first direction; the driving mechanism is transmission-connected to the two limiting members 422, and 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 in sequence along the second direction; the outer protective film 41 includes a first protective film 411 and a second protective film 412 connected to each other, and 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 at 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 limit members 422, the outer protective film 41 can be supported and limited; when the limit members 422 are in the first position, the first protective film 411 and the second protective film 412 are respectively located on the top of the two limit members 422, and the two limit 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; in the process of the limit 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, and the ends of the first protective film 411 and the second protective film 412 away from the connection gradually approach each other, gradually wrapping 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, it also includes a control system, which is communicatively connected to the moving mechanism; the limiting assembly also 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 the two limiting members 422 are both 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 is communicatively connected to the control system; when the two limiting members 422 approach each other, the control system controls the clamp 31 to clamp the third assembly and move to the side close 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 clamp 31 to move to 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 is helpful to support and fix the outer protective film 41, prevent the first protective film 411 and the second protective film 412 from falling, and realize that the third component is firmly placed between the first protective film 411 and the second protective film 412; and 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 a set value, the control system controls the clamping jaw 31 to move to the side away from the placement plate 423 to prevent the clamping jaw 31 from continuing to push the third component to approach the placement plate 423, thereby effectively avoiding damage to the to-be-packaged board in the third component due to excessive extrusion; by setting the control system, the placement plate 423 and the first pressure sensor 424, not only the stability of the packaging is enhanced, but also the automation level and safety of the entire packaging process are significantly improved.

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

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

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

[0047] Because when the two limit members 422 are close to each other and in the second position, the third component and the outer protective film 41 are both located between the two limit members 422, and two pressure sensors are respectively arranged on the side where the two limit 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 driving mechanism to stop driving to prevent the two limit members 422 from continuing to approach each other and causing squeezing of the third component, thereby avoiding squeezing damage that may be suffered by the packaged board and ensuring the yield rate of the product; by arranging the second pressure sensor 425, not only the accuracy of the packaging is improved, but also the safety and reliability of the entire packaging process are significantly enhanced.

[0048] In one embodiment, the second packaging mechanism 4 also includes two groups of limiting rollers 43, and the two groups of limiting rollers 43 are respectively movably arranged above the two limiting members 422. When the limiting members 422 are in the first position, the limiting rollers 43 abut against the top of the outer protective film 41; when the limiting members 422 move from the first position to the second position, the limiting rollers 43 rotate to the side 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 the coordinated action 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, thereby preventing the limiting roller 43 from obstructing the first protective film 411 or the second protective film 412 during the process of rotating to the position between the two limiting members 422; by setting the limiting roller 43, not only the degree of automation of the packaging is improved, but also the stability and smoothness of the entire packaging process are ensured.

[0050] In one embodiment, the second packaging mechanism 4 also includes a swinging assembly 44, which includes a swinging shaft, a swinging gear 441 and a first lifting assembly 442; the swinging shaft is arranged adjacent to the outer protective film 41 along the second direction, is rotatably arranged on the top of the limit member 422, and extends along the first direction; the limit roller 43 is rotatably connected to the swinging shaft and is arranged perpendicular to the swinging shaft; the swinging gear 441 is sleeved on the outer periphery of the swinging shaft and is fixedly connected to the swinging gear 441; the first lifting assembly 442 is arranged on the side of the swinging shaft away from the outer protective film 41, and the lifting end of the first lifting assembly 442 is meshed with the swinging gear 441; the moving mechanism includes a driving rod 32, which is fixed to the side of the clamping jaw 31 along the second direction; when the clamping jaw 31 descends, the driving rod 32 drives the lifting end of the first lifting assembly 442 to descend, and the limiting roller 43 rotates to the side away from the outer protective film 41.

[0051] By setting up the swing component 44, the limiting roller 43 is driven to rotate toward the side away from the outer protective film 41; when the lifting end of the first lifting component 442 descends to drive 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 along with the swing shaft to the side away from the outer protective film 41.

[0052] In a specific embodiment, the limiting member 422 includes a limiting plate 4221 and two limiting side plates 4222, and the outer protective film 41 is arranged on the top of the limiting plate 4221; the two limiting side plates 4222 are respectively arranged 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 the swing shaft is rotatably connected to the swing support 443.

[0057] Since the first elastic connecting member 4423 is connected between the fixed block 4421 and the lifting block 4422, and when the limiting roller 43 abuts against the top of the outer protective film 41, the first elastic connecting member 4423 is in an extended state, the first elastic connecting member 4423 can support the lifting block 4422, ensuring that the limiting roller 43 is in an abutting state with the outer protective film 41; when the limiting roller 43 rotates toward the side away from the outer protective film 41, the lifting block 4422 descends and compresses the first elastic connecting member 4423, and drives the limiting roller 43 to rotate toward the side away from the outer protective film 41; by setting the magnetic member 4424 When the lifting block 4422 descends to abut against the fixed block 4421, the magnetic part 4424 can fix the lifting block 4422, ensuring that the limiting roller 43 is always in a separated state from the outer protective film 41 during the subsequent packaging of the outer protective film 41; through the arrangement of the fixed block 4421, the lifting block 4422, the first elastic connecting part 4423 and the magnetic part 4424, not only the stability of the system is enhanced, but also it is ensured that the limiting roller 43 can always remain in a position 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.

When the limiting roller 43 rotates to a vertical state, the lifting block 4422 descends to the bottom of the swing base to avoid obstruction to 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 implementation, the fixed block 4421 is fixed on the limiting side plate 4222, and a guide rod 4425 is provided on the top of the fixed block 4421, and the guide rod 4425 extends in the vertical direction; the lifting block 4422 is provided with a guide through hole, and the guide rod 4425 is set through the guide through hole.

[0064] By setting the flip plate 451 and the adhesive member 413, when the clamp 31 rises, the driving 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 member 413 can be adhered to the second protective film 412, thereby realizing the adhesive connection between the first protective film 411 and the second protective film 412, which not only improves the degree of automation of packaging, but also significantly enhances the firmness and reliability of packaging.

[0068] In a specific embodiment, when the clamping jaw 31 descends, it drives the driving rod 32 to descend until it abuts against the wedge surface of the wedge rod 455, and pushes the wedge rod 455 in a direction away from the first lifting assembly 442; when the driving rod 32 descends and passes through the wedge rod 455, the second elastic connecting member 456 is reset to an extended state, pushing the wedge rod 455 to reset; when the clamping jaw 31 rises and drives the driving rod 32 to rise, the driving rod 32 abuts against the bottom surface of the wedge rod 455, and drives the wedge rod 455 to rise synchronously, and the wedge rod 455 drives the lifting rod 4532 to rise synchronously, thereby driving the flipping gear 452 to rotate, and finally causing the flip plate 451 to flip. When the flip plate 451 flips to a vertical state, the clamping jaw 31 has risen to the top of the flip plate 451, and then the clamping jaw 31 continues to rise, causing the flip plate 451 to continue to flip until the adhesive member 413 is adhered to the second protective film 412.

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

[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 out from the inflation port 12, as the air tube 21 is detached, 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 sealing of the inflation port 12, preventing external air or impurities from entering the inner protective bag 11, and 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 which are arranged in sequence, and the conical tip 221 carries the conical ring 222 through the inflation port 12 and the sealing bag 23 in sequence; when the trachea 21 is pulled out, the conical ring 222, with the side with a larger diameter away from the conical tip 221, brings the sealing bag 23 to the outside of the inflation port 12 to block the inflation port 12 and achieve temporary sealing.

[0080] When the clamp 31 grabs the second component and moves it to the second packaging mechanism 4 for packaging, the air tube 21 will move accordingly. By setting the second opening on the side of the accommodating box 13 away from the second packaging mechanism 4, when the clamp 31 grabs the second component and moves it to the second packaging mechanism 4 for subsequent packaging, interference between the air tube 21 and the structure in the second packaging mechanism 4 can be avoided, which not only improves the efficiency and reliability of packaging, but also reduces the risk of equipment damage.

[0081] In a specific embodiment, the first opening is communicated with the second opening, and when the inner protection bag 11 is placed in the containing box 13 , it is helpful for the trachea 21 to enter the second opening.

[0084] Preferably, a position sensor is provided on the containing box 13; and the position sensor is communicatively connected with the control system; when the containing box 13 moves to the position where the moving mechanism is located under the transport of the conveyor belt 5, the position sensor senses the moving mechanism and sends a signal to the control system, and the control system controls the conveyor belt 5 to stop transporting to ensure that the containing box 13 remains stationary during the grasping process; at the same time, the control system controls the clamp 31 of the moving mechanism to move to the position where the containing box 13 is located, and grasps the second component; during the whole process, the position sensor, the control system and the moving mechanism cooperate closely, and the clamp 31 can accurately locate and grasp the second component, thereby ensuring the accuracy and efficiency of grasping.

When the clamping jaw 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 hinder the flipping of the flip plate 451; 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, the clamping jaw 31 stops descending, and then releases the third assembly to start rising. During the rising process of the clamping jaw 31, the driving rod 32 drives the swinging assembly 44 to rotate the limit roller 43 to the side away from the outer protective film 41. The movable rod 32 drives the flip assembly 45 to drive the flip plate 451 to flip, so that the adhesive piece 413 is attached to the second protective film 412; then the rotating motor 4211 is driven to separate the first limit plate 4221 and the second limit plate 4221, and the staff takes out the packaged components and removes the trachea 21. The inflation port 12 is provided with a sealing bag 23 to temporarily and quickly seal the inflation port 12 to prevent air leakage, and then the staff sticks a sealing sticker on the inflation port 12, and then bends the part of the outer protective film 41 that is in contact with it to one side of the inflation port 12, and finally puts it into the packaging box to complete the packaging.
