Description

Technical Field

[0001] This utility model relates to the field of automotive airbag technology, and in particular to a CAB airbag sewing fixture flip-top device. Background Technology

[0002] There is a product that requires sewing using an airbag sewing fixture. A worker uses a handle to lift the fixture's cover plate, which remains open under the action of a gas spring. After the worker lays the material, they use the handle to lower the cover plate, thus completing the sewing of the airbag. However, this process requires the worker to overcome the weight of the gas spring and the cover plate, applying approximately 6 kg of force to lift the cover plate. This significantly increases the worker's workload. Furthermore, lifting the cover plate consumes a large portion of the worker's time, indirectly increasing the production cycle time. This is especially problematic when one person operates two machines; this solution is labor-intensive, time-consuming, and increases the production cycle time.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0019] See Figures 1 to 3 The CAB air bag sewing fixture flip-top device shown includes a sewing fixture 100, a flip-top drive device 200, a lifting plate structure 300, an anti-drop device 400, and a PLC controller (not shown) for controlling the operation of the flip-top drive device 200 and the anti-drop device 400.

[0020] A sewing fixture 100 is mounted on the machine frame and used for positioning and fixing the air supply bag. In this embodiment, the sewing fixture 100 includes a lower fixture 120 for positioning and fixing the air supply bag and an upper fixture 110 movably connected to the lower fixture 120. The upper fixture 110 and the lower fixture 120 are connected by a hinge structure. The lower fixture 120 has several positioning posts 121 on its side facing the upper fixture 110 for the holes on the air supply bag to fit into. Similarly, the upper fixture 110 has several positioning blocks 111 on its side facing the lower fixture 120 that cooperate with the positioning posts 121. In use, the holes on the air supply bag are fitted with the positioning posts 121 for fixation, preventing the air supply bag from moving.

[0021] A flip-top drive device 200 is mounted on the frame and is used to drive the sewing fixture 100 to move up and down. In this embodiment, the flip-top drive device 200 includes a flip-top cylinder positioning block 210 mounted on the frame and a flip-top cylinder 220 mounted on the flip-top cylinder positioning block 210. The flip-top cylinder 220 is connected to the support arm 500 via a rod end joint bearing 230. Specifically, the rod end joint bearing 230 is fixed to the middle of the support arm 500 by a pin 10. Moreover, there are two flip-top drive devices 200, which are respectively mounted on the left and right sides of the sewing fixture.

[0022] The lifting plate structure 300 is mounted on the sewing jig 100 and connected to the flip-up drive device 200. In this embodiment, the lifting plate structure 300 includes a lifting rod 310 mounted on the sewing jig 100 and connected to one end of the support arm 500, and a plastic bearing 320 mounted on the lifting rod 310 and in contact with the sewing jig 100. Similarly, there are two lifting plate structures 300.

[0023] The anti-drop device 400 is mounted on the frame and connected to the flip-top drive device 200. In this embodiment, the anti-drop device 400 includes a fixing block 410 mounted on and connected to the frame, and an anti-drop cylinder 420 mounted on the fixing block 410 and movably connected to the other end of the support arm 500. Similarly, the fixing block 410 is fixed to the frame by pins 10, and there are two anti-drop devices 400.

[0024] This utility model also includes a fixture positioning structure 600 mounted on the frame and used to restrict the 100 degrees of freedom of the sewing fixture to prevent it from detaching. In this embodiment, the fixture positioning structure 600 includes a positioning pin cylinder 620 mounted on the frame and connected to a PLC controller for restricting the X and Y axes of the sewing fixture, and a limiting block 610 mounted on the frame for restricting the Z axis of the sewing fixture.

[0025] The working principle of this utility model is as follows: First, after the jig interaction device delivers the sewing jig 100 into position, the PLC controller controls the positioning pin cylinder 620 to extend, restricting the X / Y degree of freedom of the template, while the limit block 610 restricts the Z degree of freedom of the sewing jig 100. Subsequently, after the PLC controller detects the signal that the positioning pin cylinder 620 has extended to the correct position, it sends a signal to extend the flip-top cylinder 220. The flip-top cylinder 220 drives the support arm 500 to rise, and the lifting rod 310 at the end of the support arm 500 drives the sewing jig 100 to rise. When fixture 110 is raised and cover-flipping cylinder 220 extends to its position, a feedback signal is sent to the PLC controller. The PLC controller then sends a signal to extend anti-drop cylinder 420 to prevent fixture 110 from falling and injuring people in case of an accident. The sewn piece is then manually removed, and the pre-arranged airbag cut piece is placed on sewing fixture 100. The button connected to the PLC controller is pressed, causing anti-drop cylinder 420 to retract, cover-flipping cylinder 220 to retract, and fixture 110 to fall, completing the automatic cover-flipping operation.
