Description

Technical Field

[0001] This application relates to the field of airbag production, and in particular to an airbag coating production line. Background Technology

[0002] A curtain airbag (CAB) is a safety airbag system installed on the roof of a car to protect the heads of occupants in the event of a side collision. The CAB assembly consists of an airbag, an airbag cover, a gas generator, a gas generator bracket, and conduits.

[0003] The CAB airbag is mainly composed of two bag bodies glued together to form a complete bag. After applying glue to one bag body, the operator takes the other bag body and places it on the glue, so that the two bag bodies stick together. Then, the operator presses the bag bodies to flatten the glue, thus completing the assembly of the airbag. Finally, the operator lifts the airbag to unload it.

[0004] During this process, the automation level of the bag body's feeding, pressing, and unloading is not high, resulting in low efficiency, which needs to be improved. Summary of the Invention

[0005] To address the issue of low production efficiency due to low automation in the production of airbags, this application provides an airbag coating production line.

[0006] The airbag coating production line provided in this application adopts the following technical solution: An airbag coating production line includes the following steps: S1. Place a bag body on the feeding assembly, which will then deliver it to the gluing station. S2. The gluing device at the gluing station applies glue to the bag body. S3. Then place another bag body on the glue, so that the two bag bodies are attached together to form an airbag. S4. Next, the moving component carries the airbag to the pressing component. S5. The pressing component applies pressure to the airbag, making the two bag bodies bond more tightly to the glue, thereby fixing the two bag bodies together. S6. Finally, use the negative pressure suction cup to adsorb the airbag and move it, so that the two fixed bag bodies can be placed on the storage board for storage, thus realizing the unloading of the finished product.

[0007] By adopting the above technical solution, operators only need to place the bag body on the feeding assembly, which automatically carries the bag body to the glue coating device for adhesive application. After the adhesive is applied, the moving assembly clamps the bag body and moves it to the pressing assembly for pressing. Finally, with the help of the negative pressure suction cup, the unloading assembly automatically completes the unloading and collection of the finished product. The entire process requires no manual intervention, greatly improving production efficiency while ensuring the stability of product quality.

[0008] Optionally, the feeding assembly in S1 is mounted on the work frame. The feeding assembly includes two feeding plates and two sliding members. The feeding plates are slidably connected to the work frame. The feeding plates are horizontally arranged and connected to the sliding members. The sliding members are mounted on the work frame and are used to drive the feeding plates to move horizontally. One of the feeding plates is connected to the corresponding sliding member through a lifting cylinder. The lifting cylinder is used to drive the feeding plate to move up and down.

[0009] By adopting the above technical solution, during production, a single bag body is first placed on one of the feeding plates. Then, the sliding mechanism is activated to drive the feeding plate with the bag body to the glue application station, so that the glue application device is aligned with the bag body. Then, the glue application device is activated to apply glue to the bag body. Afterward, the sliding mechanism is activated again to reset the feeding plate. Then, the operator places another single bag body on the glue, ensuring that the upper and lower bag bodies are aligned.

[0010] When one of the feeding plates moves the bag body from the operator's position to the gluing device, another sliding component drives the feeding plate originally located at the gluing station to the operator's position. This allows the operator to place one bag body on the other feeding plate while the bag body is being glued. Then, the two sliding components are activated again to switch the positions of the two feeding plates, so that the glued bag body is located at the operator's position. This allows the operator to cover one bag body with glue while the bag body on the other feeding plate is being glued. Repeating the above steps ensures continuous feeding and gluing of the bag body without interruption, thereby improving work efficiency.

[0011] Optionally, the sliding component includes a sliding motor and a sliding rod. The sliding motor is mounted on the work frame, and the output end of the sliding motor is coaxially fixed with one end of the sliding rod. The sliding rod is horizontally mounted on the work frame and rotatably connected to the work frame. The sliding motor is used to drive the sliding rod to rotate. One of the sliding rods is threadedly connected to one of the feeding plates, and the other sliding rod is connected to a lifting cylinder and threadedly connected to the housing of the lifting cylinder.

[0012] By adopting the above technical solution, the sliding motor is started, driving the sliding rod to rotate. Since the sliding rod is threadedly connected to one of the loading plates and the housing of the lifting cylinder, the loading plate and the lifting cylinder move along the length of the sliding rod. The other loading plate is connected to the lifting cylinder, thus causing both loading plates to move simultaneously. The two sliding motors rotate in opposite directions, resulting in opposite directions of movement for the two loading plates. Simultaneously, the lifting cylinder is activated, driving one of the feeding plates to move downwards, so that the two feeding plates will not collide or interfere when they meet, thus allowing the two feeding plates to exchange positions. After the lifting cylinder carries the feeding plate to the designated position, the lifting cylinder is activated again, driving the feeding plate to move upwards, so that the two feeding plates are level, so as to feed the bag body and apply glue.

[0013] Optionally, the feeding plate is provided with a positioning pin, and each feeding plate is provided with a support plate. The positioning pin passes through the support plate, and the feeding plate is provided with a push cylinder. The output end of the push cylinder contacts the bottom wall of the support plate.

[0014] By adopting the above technical solution, when the operator places the bag body on the feeding plate, the bag body is aligned with the positioning pin and inserted. The positioning pin acts as a restraint, preventing the bag body from moving horizontally on the feeding plate, thus positioning the bag body on the feeding plate. This facilitates precise bonding of the two bag bodies, prevents the bag body from moving during the glue application process, improves the accuracy of glue application, and consequently increases the yield of airbags. After the two bag bodies are bonded together to form an airbag, the airbag needs to be removed from the feeding plate. The push cylinder is then activated, driving the support plate upward, causing the positioning pin to disengage from the support plate and thus being pulled out of the bag body. This facilitates the movement of the bag carriage on the support plate for unloading.

[0015] Optionally, the pressing assembly in S4 includes a lifting cylinder, a top plate, and a pressure plate. The lifting cylinder is mounted on the work frame, and its output end is connected to the top plate. The lifting cylinder is used to drive the top plate to move up and down. The top plate can be flush with the loading plate, and the moving assembly can slide on the top plate.

[0016] By adopting the above technical solution, when the bag body is covered with glue, so that the two bag bodies are attached to each other to form an airbag, the moving component is activated to drive the airbag on the feeding plate to the top plate. Then, the lifting cylinder is activated to move the top plate with the airbag upward until the airbag comes into contact with the pressure plate. At this time, the top plate presses the airbag onto the pressure plate, so that the two bag bodies come closer to each other and squeeze, pressing the glue into a flat shape, increasing the contact area between the glue and the bag body, thereby increasing the tightness of the adhesion between the glue and the bag body, and thus improving the stability of the bonding between the two bag bodies, and improving the quality of the finished airbag.

[0017] Optionally, the moving component in S4 includes a moving frame, a moving part, and a clamping part. The moving frame is connected to the work frame through the moving part. The moving part is used to drive the moving frame to move horizontally. The clamping part is disposed on the moving frame. The support plate has a notch on the side near the moving frame. The clamping part can be inserted into the notch and clamp and fix the airbag bag.

[0018] By adopting the above technical solution, after the two bag bodies on the feeding plate are glued together, the moving component is activated, driving the moving frame to move towards the feeding plate, so that the clamping component is inserted into the notch. Then, the clamping component is activated, clamping the edges of the two bag bodies. Subsequently, the moving component drives the moving frame to move away from the feeding plate, that is, the moving frame slides on the top plate until the moving plate reaches the end of the top plate, at which point the airbag is completely located on the top plate. At this time, the clamping component releases the airbag, thus placing the airbag on the top plate, realizing the handling of the airbag.

[0019] Optionally, the movable frame is provided with two rows of air tubes, one row of air tubes having its output end facing the flattened surface, and the other row of air tubes having its output end facing the top plate.

[0020] By adopting the above technical solution, when the moving frame moves along the length of the top plate and carries the airbag to the top plate, the air blowing pipes are activated. The row of air blowing pipes facing the top plate blows air onto the surface of the top plate, thereby blowing away impurities from the top plate and cleaning the top plate. Meanwhile, the row of air blowing pipes facing the pressure plate blows air onto the pressure plate, thereby blowing away impurities from the pressure plate and cleaning the pressure plate. This ensures that no impurities adhere to the bag body when it is squeezed on the top plate and the pressure plate, thereby improving the yield rate of the airbag.

[0021] Optionally, the clamping component includes a fixed plate, a clamping plate, and a clamping cylinder. The fixed plate is fixed to the movable plate. The clamping plate is connected to the movable frame via the clamping cylinder. The clamping cylinder is located on the work frame. The output end of the clamping cylinder is connected to the clamping plate. The clamping cylinder is used to drive the clamping plate to move up and down. The clamping plate is located above the fixed plate.

[0022] By adopting the above technical solution, in the initial state, the clamping cylinder drives the clamping plate to move upward, so that there is a gap between the clamping plate and the fixed plate. When the moving frame inserts the fixed plate into the notch, the airbag is inserted between the fixed plate and the clamping plate. Then, the clamping cylinder is activated to drive the clamping plate to move downward until it contacts the airbag, thereby pressing and fixing the airbag on the fixed plate, realizing the clamping and fixing of the airbag. Then, the moving frame is driven to move, so that the airbag can be pulled out into a tray.

[0023] Optionally, the pressure plate is provided with a plurality of cleaning components, which are evenly arranged along the length of the pressure plate. Each cleaning component includes a worm, a worm wheel, a rotating roller, and a plurality of cleaning strips. The worm and the worm wheel are rotatably connected to the pressure plate. The worm wheel meshes with the worm. The worm wheel is connected to the rotating roller through a connecting rod. The rotating roller can rotate on the connecting rod and can be located between the pressure plate and the top plate. One end of each cleaning strip is fixed to the rotating roller and can contact the bottom wall of the pressure plate.

[0024] By adopting the above technical solution, the rotating roller is located below the edge of the pressure plate. When the air blowing pipe blows air upwards to clean the pressure plate, the cleaning strips located below the pressure plate are all pushed upwards by the air, causing the cleaning strips to move from bottom to top. This causes the rotating roller to rotate. At this time, driven by several cleaning strips, the airflow below the pressure plate becomes vortex-shaped, and the airflow direction is from bottom to top and from inside to outside. As a result, when dust and other impurities on the pressure plate are blown off, they slide outwards from the edge of the pressure plate under the influence of the airflow, preventing impurities from falling directly onto the top plate and affecting the quality of the airbag after it is placed and pressed into the finished product. During the movement, the cleaning strips come into contact with the pressure plate and clean it, improving the cleanliness of the pressure plate.

[0025] When the airbag is placed on the top plate and needs to be compressed, the worm gear is driven to rotate, which in turn drives the worm wheel to rotate. This causes the connecting rod to carry the rotating roller in a circular motion around the worm wheel as the axis. As a result, the rotating roller moves out from under the pressure plate and flips over the pressure plate, thus opening the rotating roller and leaving the area under the pressure plate unobstructed, which facilitates the top plate moving upward.

[0026] Optionally, the storage plate is connected to the work frame via a storage assembly, which includes a conveyor belt, a support plate, a base plate, and a moving cylinder. The conveyor belt is horizontally mounted on the work frame, and both the driving and driven wheels of the conveyor belt are coaxially fixed with screws. The screws are vertically mounted, and the thread structures of the two screws are opposite. The storage plate is placed on the support plate and the base plate. The support plate is sleeved on one of the screws and threadedly connected to it. The base plate is sleeved on the other screw and threadedly connected to it. The work frame is provided with a guide rod parallel to the screws. The support plate and the base plate are sleeved on the guide rod and can move vertically along the guide rod. The moving cylinder is located on the work frame and can push the storage plate on the support plate onto the base plate.

[0027] By adopting the above technical solution, in the initial state, the support plate is located at the bottom end of the screw, and several storage plates are stacked on the support plate, while the bottom plate is located at the top end of the screw, ensuring that the height of the bottom plate is below the topmost storage plate on the support plate, and its moving cylinder is aligned with the topmost storage plate on the support plate. After the negative pressure suction cup adsorbs the airbag and moves it to the topmost storage plate on the support plate, the moving cylinder is activated, driving the storage plate to move towards the bottom plate until the topmost storage plate separates from the storage plates stacked below and falls onto the bottom plate.

[0028] The conveyor belt is then activated, causing the two screws to rotate synchronously in the same direction, but with opposite thread structures. Both the support plate and the base plate are threadedly connected to the screws and, under the constraint of the guide rod, are driven to move along the length of the screws in opposite directions. Specifically, the support plate moves upward, causing the topmost storage plate on the support plate to detach from it, while the lower storage plates move to the moving cylinder, ensuring the cylinder remains aligned with the topmost storage plate on the support plate. Simultaneously, the base plate moves downward, the same distance as the support plate moves upward. This allows the base plate, after receiving one storage plate, to be positioned at a height sufficient to receive the next, and so on. This achieves automatic unloading of finished airbags after they are placed on the storage plates, improving overall production efficiency.

[0029] In summary, this application includes at least one of the following beneficial effects: 1. When one of the feeding plates moves the bag body from the operator's position to the glue application device, another sliding component drives the feeding plate originally located at the glue application station to the operator's position. This allows the operator to place one bag body on the other feeding plate while the bag body is being glued. Then, the two sliding components are activated again to switch the positions of the two feeding plates, so that the glued bag body is located at the operator's position. This allows the operator to cover one bag body with glue while the bag body on the other feeding plate is being glued. Repeating the above steps enables continuous feeding of the bag body and continuous glue application without interruption, thereby improving work efficiency. 2. Start the conveyor belt to make the two screws rotate synchronously. The two screws rotate in the same direction, but the screw threads are opposite, which drives the support plate and the base plate to move along the length of the screws in opposite directions. When the support plate moves up, the top storage plate on the support plate is removed from the support plate. Then the next storage plate moves to the moving cylinder under the support of the support plate, so that the moving cylinder is always aligned with the top storage plate on the support plate. Meanwhile, the base plate moves downwards, and the distance it moves is the same as the distance the support plate moves upwards. This allows the base plate, after receiving one storage plate, to be at the same height as the storage plate above it, so that it can receive the next storage plate. In this way, the support plate and the base plate work together throughout the process. The number of storage plates on the support plate decreases and moves upwards, while the number of storage plates on the base plate increases and moves downwards. This keeps the highest point on the support plate and the base plate constant, enabling automatic unloading of the finished airbag after it is placed on the storage plate, thus improving overall production efficiency.

[0032] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0033] Example 1: Embodiment 1 of this application discloses an airbag coating production line. (Refer to...) Figure 1 and Figure 2The airbag coating production line includes a feeding component 10, a coating device 80, a moving component 40, a pressing component 30, and a discharging component. The components are connected by precise mechanical structures and cooperation to achieve automated feeding, coating, pressing, and discharging of the bag body, thereby improving production efficiency and ensuring product quality.

[0034] Reference Figure 1 and Figure 2 Specifically, the feeding assembly 10 includes two feeding plates 11 and two sliding members 12. The feeding plates 11 are horizontally positioned and slidably connected to the work frame. Each feeding plate 11 is driven to move horizontally by the sliding member 12. One of the feeding plates 11 is also connected to the sliding member 12 via a lifting cylinder 13, which drives the feeding plate 11 to move up and down. The sliding member 12 includes a sliding motor 121 and a sliding rod 122. The sliding motor 121 is bolted to the work frame, and its output end is coaxially fixed to one end of the sliding rod 122. The sliding rod 122 is horizontally positioned on the work frame and rotatably connected to it. The sliding motor 121 drives the sliding rod 122 to rotate. One sliding rod 122 is threadedly connected to one of the feeding plates 11, and the other sliding rod 122 is threadedly connected to the housing of the lifting cylinder 13. The rotation of the sliding rod 122 is converted into the horizontal movement of the feeding plate 11 through the screw drive, thereby achieving precise positioning of the bag body.

[0035] Reference Figure 1 and Figure 2 The glue application device 80 is installed on the work frame and is aligned with one of the feeding plates 11 to apply glue to the bag body on the feeding plate 11. The glue application device 80 at the glue application station is a dispensing machine. The nozzle of the dispensing machine can precisely control the flow rate and position of the glue to ensure uniform glue application.

[0036] When one of the feeding plates 11 moves the bag body from the operator's position to the glue application device 80, the other sliding member 12 drives the feeding plate 11, which was originally located at the glue application station, to the operator's position. This allows the operator to place one bag body on the other feeding plate 11 while the bag body is being glued. Then, the two sliding members 12 are activated again to replace the positions of the two feeding plates 11, so that the glued bag body is located at the operator's position. This allows the operator to cover one bag body with glue while the bag body on the other feeding plate 11 is being glued. By repeating the above steps, the feeding of the bag body and the glue application of the bag body can be carried out continuously without interruption, thereby improving work efficiency.

[0037] Reference Figure 1 and Figure 2In addition, the feeding plate 11 is provided with a positioning pin 111 and a support plate 20. The positioning pin 111 passes through the support plate 20. When the operator places the bag body on the feeding plate 11, the bag body is aligned with the positioning pin 111 and inserted. The positioning pin 111 plays a restrictive role, preventing the bag body from moving horizontally on the feeding plate 11, thus achieving the positioning of the bag body on the feeding plate 11 and facilitating the precise fitting of the two bag bodies.

[0038] Reference Figure 1 and Figure 2 The feeding plate 11 is also equipped with a push cylinder 112, the output end of which contacts the bottom wall of the support plate 20. Driven by air pressure, the push cylinder 112 can smoothly lift the support plate 20, thereby pulling the support plate 20 away from the positioning pin 111, so that the bag body can move horizontally on the support plate 20.

[0039] Reference Figure 1 and Figure 3 The pressing assembly 30 includes a lifting cylinder 31, a top plate 32, and a pressure plate 33. The lifting cylinder 31 is mounted on the work frame, and its output end is connected to the top plate 32. The lifting cylinder 31 is used to drive the top plate 32 to move up and down, so that the top plate 32 can be flush with the loading plate 11. The moving assembly 40 can slide on the top plate 32. The moving assembly 40 includes a moving frame 41, a moving part 42, and a clamping part 43. The moving frame 41 is connected to the work frame through the moving part 42. The moving part 42 is used to drive the moving frame 41 to move horizontally. The moving part 42 is a lead screw motor. The moving frame 41 is slidably connected to the work frame and threadedly connected to the lead screw. This is prior art and will not be described in detail here.

[0040] Reference Figure 3 and Figure 4 The clamping member 43 is mounted on the movable frame 41 and is used to clamp and fix the airbag. The movable frame 41 has two rows of air-blowing pipes 411, with the output end of one row of air-blowing pipes 411 facing the pressure plate 33 and the output end of the other row facing the top plate 32. The air-blowing pipes 411 can be made of high-temperature resistant plastic to ensure stable operation even in high-temperature environments.

[0041] Reference Figure 3 and Figure 4 The clamping component 43 includes a fixed plate 431, a clamping plate 432, and a clamping cylinder 433. The fixed plate 431 is fixed on the moving plate. The clamping plate 432 is connected to the moving frame 41 through the clamping cylinder 433. The clamping cylinder 433 is bolted to the work frame, and its output end is connected to the clamping plate 432. The clamping cylinder 433 is used to drive the clamping plate 432 to move up and down. The clamping plate 432 is located above the base plate 73. A notch 21 is provided on the side of the support plate 20 near the moving frame 41 so that the fixed plate 431 and the clamping plate 432 can be inserted into the notch 21.

[0042] When the bag body is covered with glue, so that the two bag bodies are attached to each other to form an airbag, the moving part 42 is activated, driving the moving frame 41 to move towards the upper material plate 11, so that the clamping plate 432 and the fixing plate 431 are both moved into the notch 21. The edge of the airbag is inserted between the fixing plate 431 and the clamping plate 432. Then, the clamping cylinder 433 is activated, driving the clamping plate 432 to move down until it contacts the airbag, thereby pressing and fixing the airbag onto the fixing plate 431, realizing the clamping and fixing of the airbag. The clamping plate 432 is made of rubber, which has good flexibility and can closely fit the surface of the bag body to avoid damage to the bag body during the clamping process.

[0043] Next, the moving frame 41 is driven to move away from the loading plate 11, which allows the airbag to be detached into a pallet. At the same time, the moving frame 41 slides on the top plate 32 until the moving plate reaches the end of the top plate 32, at which point the airbag is completely located on the top plate 32. At this point, the clamping member 43 releases the airbag, thereby placing the airbag on the top plate 32, thus realizing the handling of the airbag.

[0044] The implementation principle of Embodiment 1 of this application is as follows: the feeding component 10 realizes the automated feeding of the bag body, the glue coating station completes the glue coating operation of the bag body, and the moving component 40 drives the airbag bag to the pressing component 30 for pressing. The whole process does not require manual intervention, which greatly improves production efficiency and ensures the stability of product quality.

[0045] Example 2: The difference between Embodiment 2 and Embodiment 1 of this application is as follows: Reference Figure 5 and Figure 6 A plurality of cleaning components 50 are provided on the pressure plate 33, and the cleaning components 50 are evenly distributed along the length of the pressure plate 33. Each cleaning component 50 includes a worm gear 51, a worm wheel 52, a rotating roller 53, and a plurality of cleaning strips 54. The worm gear 51 and the worm wheel 52 are rotatably connected to the pressure plate 33. A motor is mounted on the pressure plate 33, and the output end of the motor is coaxially fixed to the worm gear 51 to drive the worm gear 51 to rotate. The worm wheel 52 meshes with the worm gear 51 and is connected to the rotating roller 53 via a connecting rod. The rotating roller 53 can rotate on the connecting rod and can be located between the pressure plate 33 and the top plate 32, and is located below the edge of the pressure plate 33. One end of each cleaning strip 54 is fixed to the rotating roller 53, and the cleaning strip 54 can contact the bottom wall of the pressure plate 33. Brushes are fixed to the periphery of each cleaning strip 54, and the brushes can move against the pressure plate 33.

[0046] When the air blowing pipe 411 blows air upwards to clean the pressure plate 33, the cleaning strips 54 located below the pressure plate 33 are all pushed upwards by the air, causing the cleaning strips 54 to move from bottom to top. This causes the rotating roller 53 to rotate. At this time, driven by several cleaning strips 54, the airflow below the pressure plate 33 becomes vortex-shaped, and the airflow direction is from bottom to top and from inside to outside. As a result, when dust and other impurities on the pressure plate 33 are blown off, they slide outwards from the edge of the pressure plate 33 under the influence of the airflow, preventing impurities from falling directly onto the top plate 32 and affecting the quality of the airbag after it is placed and pressed into the finished product. During the movement of the cleaning strips 54, the brushes will come into contact with the pressure plate 33 and clean the pressure plate 33, improving the cleanliness of the pressure plate 33.

[0047] When the airbag is placed on the top plate 32 and needs to be compressed, the worm gear 51 is driven to rotate, which in turn drives the worm wheel 52 to rotate. This causes the connecting rod to carry the rotating roller 53 to make a circular motion around the worm wheel 52 as the axis. As a result, the rotating roller 53 moves out from under the pressure plate 33 and flips over the pressure plate 33, thus opening the rotating roller 53 and making the area under the pressure plate 33 unobstructed, which facilitates the upward movement of the top plate 32.

[0048] Reference Figure 5 and Figure 7 The storage plate 60 is connected to the work frame via a storage assembly 70, which includes a conveyor belt 71, a support plate 72, a base plate 73, and a moving cylinder 74. The conveyor belt 71 is horizontally mounted on the work frame, and both its drive wheel and driven wheel are coaxially fixed with screws 75. The drive wheel of the conveyor belt 71 is driven to rotate by a motor, which is mounted on the work frame.

[0049] Reference Figure 5 and Figure 7 The screws 75 are vertically arranged, and the thread structures of the two screws 75 are opposite. The storage plate 60 is placed on the support plate 72 and the base plate 73. The support plate 72 is sleeved on one of the screws 75 and threadedly connected to the screw 75. The base plate 73 is sleeved on the other screw 75 and threadedly connected to the screw 75.

[0050] Reference Figure 5 and Figure 7 Guide rods 76 are provided on both the support plate 72 and the base plate 73. The guide rods 76 are parallel to the screw 75, and the support plate 72 and the base plate 73 can move vertically along the corresponding guide rods 76. The moving cylinder 74 is bolted to the work frame and can push the storage plate 60 on the support plate 72 onto the base plate 73.

[0051] In the initial state, the support plate 72 is located at the bottom end of the screw 75, and several storage plates 60 are stacked on the support plate 72. The bottom plate 73 is located at the top end of the screw 75, ensuring that the height of the bottom plate is below the topmost storage plate 60 on the support plate 72. The moving cylinder 74 is aligned with the topmost storage plate 60 on the support plate 72. When the negative pressure suction cup adsorbs the airbag and moves it to the topmost storage plate 60 on the support plate 72, until 4-5 airbags are stacked on a storage plate 60, the moving cylinder 74 is activated, driving the storage plate 60 to move towards the bottom plate 73, until the topmost storage plate 60 separates from the storage plates stacked below and falls onto the bottom plate 73.

[0052] Then, the conveyor belt 71 is activated, causing the two screws 75 to rotate synchronously. The two screws 75 rotate in the same direction, but their thread structures are opposite. The support plate 72 and the base plate 73 are both threadedly connected to the screws 75. Under the constraint of the guide rod 76, the support plate 72 and the base plate 73 are driven to move along the length of the screws 75 in opposite directions. That is, the support plate 72 moves upward, causing the uppermost storage plate 60 on the support plate 72 to detach from the support plate 72. The lower storage plate 60 moves to the moving cylinder 74, so that the moving cylinder 74 is always aligned with the uppermost storage plate 60 on the support plate 72. Meanwhile, the base plate 73 moves downward, and the moving distance of the base plate 73 is the same as the moving distance of the support plate 72. This allows the base plate 73 to support one storage plate 60, and the height of the base plate 73 and the storage plate 60 above it can support the next storage plate 60. This process is repeated to achieve automatic unloading of the finished airbag after it is placed on the storage plate 60, thereby improving the overall production efficiency.

[0053] The implementation principle of Embodiment 2 of this application is as follows: During the process of moving the airbag on the top plate 32, the cleaning component 50 ensures the cleanliness of the pressure plate 33 of the top plate 32, so that the pressed airbag is not affected by impurities, that is, the finished airbag is less likely to bulge and break. Finally, the support plate 72 and the bottom plate 73 cooperate. When the support plate 72 rises, the bottom plate 73 falls, so that when the storage plate 60 is transferred on the support plate 72 and the bottom plate 73, the highest point of the support plate 72 and the bottom plate 73 can still maintain a special height to support the subsequent storage plate, realize automated material collection, and improve production efficiency.

[0054] This embodiment provides an operation method for an airbag coating production line, including the following steps: S1. Place a bag body on the feeding assembly 10 and send it to the glue coating station. The specific operation is as follows: start the sliding motor 121, and drive the feeding plate 11 to move horizontally through the rotation of the sliding rod 122, so as to transport the bag body to the glue coating station.

[0055] S2. The glue applicator 80 at the glue applicator station applies glue to the bag body. The specific operation is as follows: adjust the height and angle of the nozzle of the glue applicator to make the glue evenly applied to the surface of the bag body.

[0056] S3. Then place another bag body on the glue, so that the two bag bodies are attached together to form an airbag.

[0057] S4. Next, the moving component 40 carries the airbag to the pressing component 30. During this process, the airbag is first lifted by the push cylinder 112 and placed on the feeding component 10. Then, the moving component 42 is started to drive the moving frame 41 to move horizontally and send the airbag to the top plate 32.

[0058] S5. The pressing assembly 30 applies pressure to the airbag, making the two bag bodies bond more tightly with the glue, thereby fixing the two bag bodies together. The specific operation is as follows: start the lifting cylinder 31, drive the top plate 32 to move up to abut against the pressure plate 33, apply pressure to the airbag, and complete the pressing.

[0059] S6. Finally, the negative pressure suction cups are used to adsorb and move the airbags, thereby placing the two fixed bag bodies on the storage plate 60 for storage, thus completing the unloading of the finished product. The specific operation is as follows: start the vacuum pump, use the suction cup array to adsorb the airbags and move them to the storage plate 60 to complete the unloading.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
