Description

Technical Field

[0001] The invention relates to the technical field of automobile safety belt sewing, in particular to a short webbing sewing device for a safety belt. Background Art

[0002] In the automobile safety system, seat belts play a vital role. When a car encounters an accident, the seat belts need to effectively shrink in length to firmly fix the driver and passengers in the seats and absorb part of the impact force. This is a key line of defense to protect the safety of the driver and passengers. As an important component of the seat belt, the sewing quality of the short webbing directly affects the overall performance of the seat belt.

[0003] At present, the market demand for sewing short webbing is increasing, but the production method mainly relies on manual operation. Manual sewing has many disadvantages. Specifically, it is difficult to ensure the consistency of the sewing position of each short webbing. The differences in operations by different operators or the same operator at different times will cause large deviations in the sewing position, which will affect the stability and reliability of the seat belt during use. In addition, the manual sewing speed is relatively slow, which is difficult to meet the needs of large-scale production, resulting in an extension of the production cycle and an inability to respond to the large market demand for seat belts in a timely manner. A large amount of manual input also means that high labor costs need to be borne. In addition, long-term repetitive labor can easily make operators tired, increase the risk of operational errors, and thus lead to safety accidents. At the same time, some factors in the production environment, such as noise and dust, can also cause potential harm to the health of operators.

[0022] More specifically, in this embodiment, the safety belt short webbing sewing equipment is turned on to ensure that the frame 1 is stable and that each mechanism is firmly installed and in the initial state. The frame 1 serves as the basic support for the entire device and provides an installation platform for the long webbing clamping mechanism 2, the short webbing material shifting mechanism 3, the short webbing suction mechanism 4, the short webbing shaping and transplanting mechanism 5, the short webbing clamping mechanism 6, the short webbing folding mechanism 7, the long and short webbing pressing mechanism 8, and the long and short webbing sewing mechanism 9. In addition, check whether the conveying device 10 is operating normally. The conveying device 10 is installed separately. It is installed on the side of the long ribbon clamping mechanism 2 away from the long and short ribbon sewing mechanism 9 and at the discharge of the long and short ribbon sewing mechanism 9, and is used for the input of long ribbon and the output of sewn finished products. The long ribbon is transmitted to the long ribbon clamping mechanism 2 through the conveying device 10. The long ribbon clamping mechanism 2 is started to clamp the long ribbon delivered by the conveying device 10. The long ribbon clamping mechanism 2 places the long ribbon on the long and short ribbon pressing mechanism 8. The servo system 21 in the long and short ribbon sewing mechanism 9 starts to work, and the long ribbon is adjusted to the accurate position for sewing the short ribbon through servo movement.

[0023] At the same time, the short webbing is manually placed in the transfer box 11 of the short webbing material transfer mechanism 3. The transfer box 11 is used to place the short webbing, and the driving part of the short webbing material transfer mechanism 3 is used to push the short webbing to the material taking position of the short webbing suction mechanism 4.

[0024] Furthermore, the short webbing suction mechanism 4 includes a suction cup 12, which is driven by the driving portion of the short webbing suction mechanism 4 to suck the short webbing to the short webbing shaping and transplanting mechanism 5. The short webbing shaping and transplanting mechanism 5 includes a suction cup group 13, a first cylinder group 14, a pulley group 15 and a shaping slider 22. The suction cup group 13 is used to suck the short webbing, the driving portion of the first cylinder group 14 is connected to the sliding end of the pulley group 15, and the shaping slider 22 is slidably connected to the sliding end of the pulley group 15.

[0025] It is worth noting that the driving part of the short webbing material shifting mechanism 3 is actuated to push the short webbing in the shifting box 11 to the material picking position of the short webbing suction mechanism 4. The driving part of the short webbing suction mechanism 4 drives the suction cup 12 to move downward, and the suction cup 12 sucks the short webbing and moves upward. The driving part of the short webbing suction mechanism 4 continues to act to move the sucked short webbing to the short webbing shaping and transplanting mechanism 5 and puts down the short webbing. The suction cup group 13 of the short webbing shaping and transplanting mechanism 5 sucks the short webbing put down by the short webbing suction mechanism 4. At the same time, the driving part of the first cylinder group 14 is started to drive the sliding end of the pulley group 15 to move. Since the shaping slider 22 is slidably connected to the sliding end of the pulley group 15, the shaping slider 22 moves accordingly to perform a shaping operation on the short webbing. After the shaping is completed, some cylinders in the first cylinder group 14 are pushed forward to the designated position to prepare for the subsequent transfer of the short webbing. Preparation, the driving end of the second cylinder group 16 of the short webbing clamping mechanism 6 moves forward at the same time and clamps the short webbing shaped by the short webbing shaping and transplanting mechanism 5, and the servo motor of the short webbing clamping mechanism 6 is started, driving the short webbing to move upward to the short webbing folding mechanism 7, and the driving end of the third cylinder group 17 of the short webbing folding mechanism 7 moves at the same time to drive the folding knife 18 to fold the short webbing.

[0026] Finally, since the sewing part of the long and short webbing sewing mechanism 9 is located above the short webbing folding mechanism 7 and the long and short webbing pressing mechanism 8, after the long and short webbings are adjusted to the accurate sewing position, the sewing part starts and the long and short webbings are sewn. After the sewing is completed, the cylinder of the short webbing clamping mechanism 6 moves forward and clamps the sewn short webbing, and then drives the sewn short webbing to move backward, and then releases the sewn short webbing. Subsequently, the sewn finished product is output through the conveying device 10 at the discharge point of the long and short webbing sewing mechanism 9, completing the entire short webbing sewing process, and the various mechanisms of the equipment return to their initial state, waiting for the next round of operation.

The driving end of the third cylinder group 17 of the short webbing folding mechanism 7 drives the folding knife 18 to fold the short webbing. During the folding process, some cylinders of the short webbing clamping mechanism 6 move to pull out the short webbing and clamp it again; After folding is completed, the third cylinder group 17 drives the unit to extract the folding knife 18.

[0031] Transfer and sewing of short webbing: The motor of the short webbing clamping mechanism 6 drives the support plate 20 to move through the gear rack device 19.
