Description

Technical Field

[0001] This utility model relates to an airbag winding and molding robot for winding adhesive strips around the conical head of an airbag. Background Technology

[0002] Currently, the cone-shaped head of the airbag is generally made by manually wrapping the rubber strip, which is inefficient and labor-intensive. In addition, the force is not evenly controlled when manually wrapping the rubber strip, resulting in poor control of the connection gap. Consequently, the wrapped rubber strip does not fit well on the cone-shaped head surface, and bulging or bridging may occur after heating, affecting product quality. Summary of the Invention

[0003] To address the aforementioned technical shortcomings, this invention provides an airbag winding molding robot that ensures the adhesive strip tightly and evenly covers the airbag cone head, thereby improving the airtightness and stability of the airbag.

[0004] This utility model is achieved through the following measures:

[0005] An airbag winding forming robot includes an airbag winding frame. The airbag winding frame includes two horizontally extending and parallel-spaced lifting rollers. An airbag extending horizontally to the left and right is supported above the two lifting rollers. The two lifting rollers include a front driven roller and a rear driving roller. Fixed bearing seats are provided at both ends of the rear driving roller. At least two sliding guide rails extending forward and backward are laid below the front driven roller. Sliding bearing seats that can slide along the sliding guide rails are connected to both ends of the front driven roller. A robotic arm that can translate left and right and can rotate is provided at the rear side of the airbag winding frame. A glue strip assembly is provided at the end of the robotic arm. The glue strip assembly includes a magnetic powder brake. A reel is rotatably connected to one side of the magnetic powder brake. Limiting discs are symmetrically provided at both ends of the reel. A glue strip is wound on the reel between the two limiting discs. The circumferential surface of the annular gap formed between the two limiting discs is close to the surface of the conical head of the airbag.

[0006] The rear side of the aforementioned airbag winding frame is provided with horizontally extending tracks. The bottom of the robotic arm is provided with a base that can move along the tracks. The robotic arm is a six-axis industrial robotic arm. The robotic arm includes a power control mechanism fixed on the base. A lower cantilever is connected to the power control mechanism via a joint motor. An upper cantilever is connected to the lower cantilever via a joint motor. A support frame is provided at the end of the upper cantilever. The magnetic powder brake is provided on the support frame.

[0007] The track is provided with toothed bars extending to the left and right. A translation motor is provided on the base. The translation motor drives a gear that passes through the base and meshes with the toothed bars.

[0008] The aforementioned sliding guide rail is equipped with a lead screw extending forward and backward, and a sliding motor connected to the lead screw is provided at the front end of the sliding guide rail. A nut that cooperates with the lead screw is provided at the bottom of the sliding bearing seat.

[0009] The support frame at the end of the upper cantilever includes two circular support plates. The magnetic powder brake is disposed between the two support plates, and several isolation columns are connected between the edges of the two support plates. A drive shaft is connected between the center of the magnetic powder brake and the reel.

[0010] The beneficial effects of this utility model are: by using a robotic arm to precisely control the winding path and force of the adhesive strip on the surface of the airbag, the speed of the airbag winding frame rotating with the airbag is matched with the speed at which the adhesive strip is emitted by the robotic arm; the robotic arm can flexibly adjust the winding angle and speed according to a preset program to ensure that the adhesive strip tightly and evenly covers the airbag cone head, improving the airtightness and stability of the airbag, effectively avoiding the gaps and non-adhesion problems that may occur in traditional winding methods, greatly improving product quality and performance, and having broad application prospects and significant innovation.

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings:

[0018] like Figure 1-5As shown, an airbag winding molding robot includes an airbag winding frame that can lift an airbag 1 that extends horizontally to the left and right. A robotic arm 2 that can move left and right and can be rotated is provided on the rear side of the airbag winding frame. An adhesive strip dispensing assembly is provided at the end of the robotic arm 2. The adhesive strip dispensing assembly includes a magnetic powder brake 15. A roller 18 is rotatably connected to one side of the magnetic powder brake 15. Limiting discs 17 are symmetrically arranged at both ends of the roller 18. An adhesive strip is wound on the roller 18 between the two limiting discs 17, and the circumferential surface of the annular gap formed between the two limiting discs 17 is close to the surface of the conical head of the airbag. The airbag winding frame includes two horizontally extending, parallel, and spaced-apart lifting rollers. An airbag extending horizontally to the left and right is supported above the two lifting rollers. The two lifting rollers include a front driven roller 8 and a rear driving roller 9. Fixed bearing seats are provided at both ends of the rear driving roller 9. The track 3 is arranged parallel to the rear of the rear driving roller 9. At least two front-to-back extending sliding guide rails 4 are laid below the front driven roller 8. Sliding bearing seats that can slide along the sliding guide rails 4 are connected to both ends of the front driven roller 8. By adjusting the front driven roller 8's front-to-back movement, the distance between the front driven roller 8 and the rear driving roller 9 can be adjusted, thus accommodating airbags of different sizes and allowing the airbag to rotate axially on the two lifting rollers during winding. A magnetic powder brake 15 can provide a certain winding force, making the tape adhere more tightly to the airbag surface.

[0019] A horizontally extending track 3 is laid on the rear side of the airbag wrapping frame. A base 10, movable along the track 3, is located at the bottom of the robotic arm 2. The robotic arm 2 includes a power control mechanism 5 fixed to the base 10. A lower cantilever 6 is connected above the power control mechanism 5 via a joint motor. An upper cantilever 7 is connected to the lower cantilever 6 via a joint motor. A support frame is located at the end of the upper cantilever 7, and a magnetic powder brake 15 is mounted on the support frame. The robotic arm 2 has high flexibility and can move left and right, and can be adjusted appropriately using preset parameters.

[0020] A toothed rack 12 extending left and right is provided inside the track 3. A translation motor 11 is provided on the base 10. The translation motor 11 drives a gear that passes through the base 10 and meshes with the toothed rack 12. A lead screw extending front and rear is provided inside the sliding guide rail 4. A sliding motor 13 connected to the lead screw is provided at the front end of the sliding guide rail 4. A nut that mates with the lead screw is provided at the bottom of the sliding bearing seat. The support frame at the end of the upper cantilever 7 includes two circular support plates 14. A magnetic powder brake 15 is provided between the two support plates 14, and several isolation posts 16 are connected between the edges of the two support plates 14. A drive shaft is connected between the center of the magnetic powder brake 15 and the reel 18.

[0021] In use, the airbag is placed on the front driven roller 8 and the rear driving roller 9. The motor drives the rear driving roller 9 to rotate axially, which in turn drives the front driven roller 8 to rotate, thus causing the airbag to rotate axially. The robotic arm 2 sets its moving speed and time according to the time required for the winding frame to rotate the airbag product. Then, a natural rubber strip is introduced to the cone head of the airbag. The robotic arm 2 and the magnetic powder brake 15 are activated simultaneously to begin winding. At this time, the tape on the airbag winding forming robot tooling will be released in an orderly manner with force, and the winding strips on the cone head surface of the airbag will adhere in an orderly manner, improving quality. The strip delivery assembly can control the tension of the strip release and retraction, ensuring that the force remains consistent after the strip is delivered. The robotic arm 2 can move and adjust in the length direction on the track 3.

[0022] This patent utilizes an airbag winding robot to control the winding path and force of the adhesive strip, achieving automated operation through a preset program, thus solving the inconsistency problem of traditional manual winding. Furthermore, the device can flexibly adjust winding parameters according to the specific needs of the airbag, improving production efficiency and product quality. This innovative design is not only applicable to the adhesive strip winding of the airbag cone head but can also be extended to other fields requiring controlled winding processes, such as composite material airbag molding and manufacturing.

[0023] The above description is only a preferred embodiment of this patent. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this patent, and these improvements and substitutions should also be considered within the scope of protection of this patent.
