Description

Technical Field

[0001] This utility model relates to the field of automotive airbag folding technology, specifically a CAB airbag folding and wrapping machine. Background Technology

[0002] In automotive safety systems, airbags play a crucial role. When a car encounters a sudden accident, airbags can deploy and unfold in a timely and effective manner, providing critical cushioning protection for drivers and passengers. They are the last solid line of defense to ensure the safety of drivers and passengers.

[0003] However, whether the airbag can be folded precisely according to the predetermined requirements is a key factor in whether it can successfully play a protective role in the event of an accident. A proper folding method can ensure that the airbag is compactly stored in a limited space, while ensuring that it can be deployed quickly and smoothly when triggered, so as to minimize the impact on the occupants. If it is folded improperly, it may cause problems such as obstruction when the airbag is deployed, insufficient deployment, or deviation in deployment direction, thereby greatly reducing its protective effect and even causing additional injuries to the occupants.

[0004] Currently, the market demand for airbags is showing a continuous growth trend. However, existing airbag production largely relies on manual operation. Specifically, different operators will use different operating habits and sequences during the folding process. Even the same operator may have different folding sequences at different times and under different conditions. This randomness makes it difficult to guarantee the folding quality of airbags consistently, increasing the uncertainty of product quality. In addition, manual operation is relatively slow and is easily affected by factors such as fatigue and emotions. With the continuous increase in market demand, manual folding is difficult to meet the requirements of large-scale production, resulting in extended production cycles and an inability to respond to market demands in a timely manner. Moreover, the large amount of manual input means that high labor costs must be borne. Utility Model Content

[0005] The purpose of this utility model is to provide a CAB air bag folding and wrapping machine, which solves the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a CAB air bag folding and wrapping machine, comprising a frame, wherein an ear-hanging mechanism, a folding mechanism, a servo motor lifting mechanism, a lifting limit mechanism, a lateral movement mechanism and a wrapping mechanism are sequentially installed on the upper surface of the frame;

[0007] The ear-hanging mechanism is installed on one side of the frame as the initial platform for placing the air bag. The folding mechanism is located below the ear-hanging mechanism. The servo motor lifting mechanism works in conjunction with the folding mechanism and is used to prevent the air bag from falling off the ear-hanging mechanism during folding. The lifting and limiting mechanism is used to position the folding mechanism and make way for the movement of the lateral mechanism. The lateral mechanism is installed on the side close to the lifting and limiting mechanism. The winding mechanism is installed on the side of the lifting and limiting mechanism away from the folding mechanism and is used to wrap the folded air bag with tape.

[0008] The above-mentioned mechanisms work together to automate the process of folding and wrapping airbags, avoiding individual differences and fatigue caused by manual operation, ensuring that the folding sequence of airbags meets standard requirements, saving labor costs, and reducing potential threats to personal safety and health during the production process.

[0009] Optionally, the folding mechanism includes a first cylinder group, an inner folding blade, an outer folding blade, and a folding blade. The driving part of the folding mechanism is fixedly connected to the first cylinder group, the inner folding blade, and the outer folding blade, and the inner folding blade and the outer folding blade are distributed symmetrically from top to bottom. The cylinder driving part in the first cylinder group is connected to the folding blade. Through precise mechanical structure design, the folding mechanism can ensure the accuracy and consistency of air bag folding, reduce the defect rate caused by folding problems, and improve the folding yield.

[0010] Optionally, the servo motor lifting mechanism includes a servo motor and a lead screw transmission device, and the drive of the servo motor is fixedly connected to the lead screw transmission device. The servo motor lifting mechanism ensures the stability of the air bag during the folding process, prevents the air bag from falling and affecting the folding effect, and further improves the accuracy and consistency of folding.

[0011] Optionally, the lateral movement mechanism includes a gear and rack engagement device, a gripping part, a sliding plate, and a second cylinder group. The driving part of the lateral movement mechanism is connected to the gear and rack engagement device, which drives the sliding plate. The cylinder driving part in the second cylinder group is connected to the gripping part. The lateral movement mechanism realizes the automatic transfer of air bags between different mechanisms, improves production efficiency, and ensures the continuity of the production process.

[0012] Optionally, the winding mechanism includes a tape gripper, a pneumatic gripper, a blade, a motor assembly, and a third cylinder assembly. The cylinder drive unit in the third cylinder assembly is connected to the tape gripper, the pneumatic gripper, and the blade. The winding mechanism completes the automatic winding of the air bag, ensuring the quality and efficiency of the winding and further improving the overall production capacity.

[0013] Optionally, a synchronous belt drive device is connected between the motor unit and the drive unit of the folding mechanism.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] I. This utility model uses automation to fold air bags strictly according to a preset program, effectively avoiding the problem of inconsistent folding order caused by individual differences and fatigue during manual operation. It ensures that the folding order of each air bag meets the standard requirements and greatly saves labor costs. In addition, after using the CAB air bag folding and wrapping machine, workers only need to monitor and maintain the equipment, thereby reducing potential threats to personal safety and health during the production process.

[0016] Second, the automated control adopted in this utility model can continuously and stably perform air bag folding and wrapping operations without being limited by time or fatigue. It can produce according to the set speed and rhythm, which greatly improves production efficiency and increases the overall production capacity. In addition, through precise servo control and mechanical structure design, the accuracy and consistency of air bag folding can be guaranteed, reducing the defect rate caused by folding problems and improving the folding yield.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Example

[0025] Please see Figures 1 to 5 This utility model provides a technical solution: a CAB air bag folding and wrapping machine, including a frame 1, on the upper surface of the frame 1 are sequentially installed an ear-hanging mechanism 2, a folding mechanism 3, a servo motor lifting mechanism 4, a lifting limit mechanism 5, a transverse movement mechanism 6 and a wrapping mechanism 7.

[0026] The ear-hanging mechanism 2 is installed on one side of the frame 1 as the initial platform for placing the air bag. The folding mechanism 3 is located below the ear-hanging mechanism 2. The servo motor lifting mechanism 4 works in conjunction with the folding mechanism 3 and is used to prevent the air bag from falling off the ear-hanging mechanism 2 during the folding process. The lifting limit mechanism 5 positions the folding mechanism 3 and makes way for the movement of the transverse mechanism 6. The transverse mechanism 6 is installed on the side close to the lifting limit mechanism 5. The wrapping mechanism 7 is installed on the side of the lifting limit mechanism 5 away from the folding mechanism 3 and is used to wrap the folded air bag with tape.

[0027] More specifically, in this embodiment, the operator first conducts a comprehensive inspection of the CAB air bag folding and wrapping machine to confirm that the frame 1 is stable, and that the ear-hanging mechanism 2, folding mechanism 3, servo motor lifting mechanism 4, lifting limit mechanism 5, lateral movement mechanism 6, and wrapping mechanism 7 on the frame 1 are firmly installed and that the electrical connections are normal. In addition, after checking whether the ear-hanging mechanism 2, folding mechanism 3, servo motor lifting mechanism 4, lifting limit mechanism 5, lateral movement mechanism 6, and wrapping mechanism 7 are in their initial state without any jamming or abnormalities, the air bag to be folded and wrapped is placed on the ear-hanging mechanism 2. The ear-hanging mechanism 2 serves as the initial platform for placing the air bag and is located on one side of the frame 1, providing initial positioning for the air bag. Subsequently, the operator arranges the air bag to make it flat and uses a scraper to fix the bottom of the air bag to the folding mechanism 3.

[0028] Furthermore, the folding mechanism 3 includes a first cylinder group 8, an inner folding blade 9, an outer folding blade 10, and a folding blade 11. The driving part of the folding mechanism 3 is fixedly connected to the first cylinder group 8, the inner folding blade 9, and the outer folding blade 10, respectively. The inner folding blade 9 and the outer folding blade 10 are symmetrically distributed vertically. The cylinder driving part in the first cylinder group 8 is connected to the folding blade 11. The servo motor lifting mechanism 4 includes a servo motor and a lead screw transmission device 12, and the drive of the servo motor is fixedly connected to the lead screw transmission device 12.

[0029] It is worth noting that the folding mechanism 3 is located below the ear-hanging mechanism 2. Specifically, it drives the inner folding blade 9 and the outer folding blade 10 to rotate via the synchronous belt drive device 22. Since the inner folding blade 9 and the outer folding blade 10 are symmetrically distributed vertically, they will clamp the air bag when they rotate. The cylinder drive unit in the first cylinder group 8 is connected to the folding blade 11. The third cylinder first drives the folding blade 11 to move forward, and then the other cylinders in the first cylinder group 8 drive the folding blade 11 to move forward in sequence, thereby gradually folding the air bag. At the same time, the servo motor lifting mechanism 4 works in coordination with the folding mechanism 3. Specifically, when the folding mechanism 3 folds the air bag, the servo motor drives the ear-hanging mechanism 2 to move downward via the lead screw drive device 12 to prevent the air bag from falling off the ear-hanging mechanism 2 during the folding process.

[0030] Furthermore, the transverse mechanism 6 includes a gear and rack engagement device 13, a gripper 14, a slide plate 15, and a second cylinder group 16. The drive unit of the transverse mechanism 6 is connected to the gear and rack engagement device 13, which drives the slide plate 15. The cylinder drive unit in the second cylinder group 16 is connected to the gripper 14.

[0031] More specifically, after the air bag is folded, the lifting and limiting mechanism 5 begins operation, positioning the folding mechanism 3. At this time, one cylinder in the lifting and limiting mechanism 5 retracts, and the other cylinder moves backward, making room for the movement of the lateral movement mechanism 6. The lateral movement mechanism 6 is installed on the side near the lifting and limiting mechanism 5 and includes a gear and rack engagement device 13, a gripper 14, a slide plate 15, and a second cylinder group 16. One cylinder in the second cylinder group 16 moves upward to hold the folded air bag in place, while the other cylinder moves upward to grip the air bag through the gripper 14. The motor drives the gear and rack engagement device 13 to work, causing the slide plate 15 to move to the right, moving the folded air bag next to the winding mechanism 7. After the lateral movement mechanism 6 moves the air bag to the designated position, the remaining cylinders in the lifting and limiting mechanism 5 move forward and downward, re-fixing and positioning the folding mechanism 3.

[0032] Finally, the winding mechanism 7 includes a tape gripper 17, a pneumatic gripper 18, a blade 19, a motor assembly 20, and a third cylinder assembly 21. The cylinder drive part of the third cylinder assembly 21 is connected to the tape gripper 17, the pneumatic gripper 18, and the blade 19, respectively. A synchronous belt drive device 22 is connected between the motor assembly 20 and the drive part of the winding mechanism 3.

[0033] Specifically, one cylinder in the third cylinder group 21 moves upward and another cylinder moves downward, causing the tape gripper 17 to clamp the tape. The motor group 20 works, and after the downward-moving cylinder moves to the designated position, the upward-moving cylinder moves upward and finally releases the tape gripper 17. The remaining cylinders move forward, and the gripper 18 grabs the folded air bag, causing the tape to stick to the folded air bag. The servo motor in the motor group 20 drives the tape to rotate through the synchronous belt drive device 22, wrapping the air bag. After the tape rotates a certain number of times, the cylinder in the third cylinder group 21 drives the blade 19 to move forward and cut the tape. The cylinder then moves backward, driving the tape backward. Subsequently, the remaining cylinders move forward to the designated position, and the gripper 18 releases the bound air bag, which falls into the tray.

[0034] The operator removes the wrapped airbags from the tray, completing the entire airbag folding and wrapping process. All mechanisms of the equipment return to their initial state, awaiting the next round of airbag folding and wrapping operations. Specifically, the inner and outer rolling blades 9 and 10 of the folding mechanism 3 stop rotating, the folding blade 11 returns to its initial position, the servo motor lifting mechanism 4 drives the hanging ear mechanism 2 back to its initial height, and the cylinders of the lifting limit mechanism 5, the lateral movement mechanism 6, and the wrapping mechanism 7 also return to their initial positions. This achieves automated folding for the CAB airbag folding and wrapping machine, effectively avoiding inconsistencies in folding sequence caused by individual differences and fatigue during manual operation. It ensures that the folding sequence of each airbag meets standard requirements and significantly saves labor. In addition to reducing labor costs, using the CAB air bag folding and wrapping machine means workers only need to monitor and maintain the equipment, thus reducing potential threats to personal safety and health during production. Furthermore, the automated control system enables continuous and stable air bag folding and wrapping operations, unaffected by time or fatigue. It can produce at a set speed and rhythm, significantly improving production efficiency and increasing overall production capacity. Moreover, precise servo control and mechanical structure design ensure the accuracy and consistency of air bag folding, reducing defect rates caused by folding problems and improving folding yield.

[0035] The overall working principle and process are as follows:

[0036] Preparation: The operator conducts a comprehensive inspection of the CAB air bag folding and wrapping machine to confirm that the frame is stable, all mechanisms are securely installed, electrical connections are normal, and all mechanisms are in their initial state without jamming or abnormalities. Then, the air bag to be folded and wrapped is placed on the ear-hanging mechanism 2, the air bag is straightened to make it flat, and the bottom of the air bag is fixed to the folding mechanism 3 with a scraper.

[0037] Airbag folding: The folding mechanism 3 drives the inner folding blade 9 and the outer folding blade 10 to rotate via a synchronous belt drive. Since the inner folding blade 9 and the outer folding blade 10 are symmetrically distributed vertically, they clamp the airbag when they rotate. The cylinder drive unit in the first cylinder group 8 is connected to the folding blade 11. The third cylinder 21 first drives the folding blade 11 to move forward, and then the other cylinders drive the folding blade 11 to move forward in sequence, gradually folding the airbag. The servo motor lifting mechanism 4 works in coordination with the folding mechanism 3. When the folding mechanism 3 folds the airbag, the servo motor drives the hanging ear mechanism 2 to move downward via the screw drive device 12 to prevent the airbag from falling off the hanging ear mechanism 2 during the folding process.

[0038] Airbag movement: After the airbag is folded, the lifting and limiting mechanism 5 starts to work. One cylinder retracts and the other cylinder moves backward to make way for the movement of the transverse mechanism 6. One cylinder in the second cylinder group 16 of the transverse mechanism 6 moves upward to hold the folded airbag, and the other cylinder moves upward to clamp the airbag through the gripper. The motor drives the gear and rack meshing device 13 to work, causing the slide plate 15 to move to the right and move the folded airbag to the side of the winding mechanism 7. After the transverse mechanism 6 moves the airbag to the designated position, the remaining cylinders in the lifting and limiting mechanism 5 move forward and downward to fix and position the folding mechanism 3 again.

[0039] Air bag winding: In the third cylinder group 21 of the winding mechanism 7, one cylinder moves upward and another cylinder moves downward, driving the tape claw 17 to clamp the tape. The motor 20 works. After the downward-moving cylinder moves to the designated position, the upward-moving cylinder moves upward and finally releases the tape claw 17. The remaining cylinders move forward and the claw 18 grabs the folded air bag, so that the tape sticks to the air bag. The servo motor in the motor group 20 drives the tape to rotate through the synchronous belt drive device 22 to wind the air bag. After the tape rotates a certain number of times, the cylinder in the third cylinder 21 drives the blade 19 to move forward and cut the tape. The cylinder then moves backward, driving the tape to move backward. The remaining cylinders move forward to the designated position, and the claw 18 releases the tied air bag, and the air bag falls into the tray.

[0040] Equipment reset: The operator removes the wrapped air bags that have fallen into the tray, and the equipment mechanisms return to their initial state, waiting for the next round of air bag folding and wrapping operations. The inner roll cutter 9 and outer roll cutter 10 of the folding mechanism 3 stop rotating, the folding cutter 11 returns to its initial position, the servo motor lifting mechanism 4 drives the hanging ear mechanism 2 back to its initial height, and the cylinders of the lifting limit mechanism 5, the horizontal movement mechanism 6 and the wrapping mechanism 7 also return to their initial positions.
