[0039] An automatic winding and tape-wrapping device for automotive side curtain airbags includes a loading table, an airbag winding mechanism, an airbag folding mechanism, a tape-applying mechanism, and a clamping winding mechanism. The loading table is used to place the airbags to be processed.

[0040] The air curtain winding mechanism is used to wind the air curtain 1 and is located above the loading platform. It includes a hollow winding mandrel 2 horizontally mounted above the loading platform via a guide rail 23 and a drive motor 22 located at one end of the winding mandrel 2; a pneumatic module is also connected between the winding mandrel 2 and the drive motor 22. The pneumatic module includes a pneumatic connector 21 connected to one end of the winding mandrel 2, and the pneumatic connector 21 is connected to the drive motor 22 via a universal steering shaft. The drive motor 22 is a servo motor. Air holes are formed on the surface of the winding mandrel 2, and these air holes communicate with the pneumatic assembly.

[0041] Lifting assemblies 25, which are cylinders, are connected to both sides of the winding mandrel. The lifting assemblies 25 are placed on the guide rail 23 via connecting sliders. The guide rail 23 is a linear guide rail. The winding mandrel 2 rotates under the drive of a drive motor and can reciprocate in both horizontal and vertical directions.

[0042] The air curtain folding mechanism is used to fold the air curtain 1, and includes a folding module disposed on one side of the loading platform and a positioning module disposed on one side of the folding module. The folding module includes a folding platform 11 for folding the air curtain and a drive displacement component 12 disposed below the folding platform 11, the drive displacement component 12 driving the folding platform 11 to reciprocate horizontally. The positioning module includes an air curtain positioning plate 4 disposed on one side of the folding platform 11 and a clamping component 3. A lifting component for reciprocating the positioning module up and down is also disposed below the positioning module.

[0043] In this invention, the bottom of the air curtain positioning plate 4 is connected to a lifting cylinder 41 via a lifting plate, the clamping assembly 3 is placed on the lifting plate via a connecting plate 31, and the upper end of the clamping assembly 3 extends through the air curtain positioning plate 4.

[0044] The clamping assembly 3 includes a set of clamping cylinders arranged side by side on both sides of the shaft 37. The cylinder shafts of the clamping cylinders are respectively connected to the upper pressure head 33 and the lower pressure head 35. One end of the upper pressure head 33 is connected to the upper pressure head clamping cylinder 36, and the middle part is pivotally connected to the shaft 37. The other end of the upper pressure head 33 extends and is positioned above the lower pressure head 35. When the clamping assembly is activated, the upper pressure head clamping cylinder 36 drives the upper pressure head 33 upward. Under the action of the pivot, the other end of the upper pressure head 33 moves towards the lower pressure head. The lower pressure head clamping cylinder 32 drives the lower pressure head 35 upward. The upper and lower pressure heads close to clamp the air curtain. The upper pressure head 33 is also provided with a vacuum suction port 34.

The tape-applying mechanism 5 is connected to the lifting module 62 via a connecting plate.

[0046] The adhesive application module includes a vertically arranged tension cylinder 51, which is connected to a set of tensioning rollers 52. A tape suction cup 54 is located below each tensioning roller 52. When the tension cylinder 51 is opened, the tape 53 passes through the tensioning rollers 52. After the tension cylinder 51 is pressed down, it provides tension for subsequent tape winding. To ensure the adhesion of the tape, the adhesive application module is equipped with a hot air outlet. A tape feeding mechanism 8 is also provided on one side of the tape application mechanism.

[0047] The clamping winding mechanism 7 includes a clamping cylinder and a motor 71 disposed on one side of the clamping cylinder. The motor 71 is connected to a drive wheel 72 disposed on a gripper.

[0049] S1. Lay the air curtain 1 to be processed flat on the loading table.

[0050] S2. The front end of the air curtain 1 enters the positioning module and is clamped by the clamping component 3. The rear end of the air curtain 1 passes under the winding mandrel and folds along the winding mandrel 2 to wrap the mandrel and complete the feeding.

[0051] S3. The positioning module of the air curtain folding mechanism descends, and the folding table moves in the horizontal direction of the positioning module under the drive of the drive displacement component, folding the air curtain into an S-shape.

[0052] S4. The air curtain on the winding mandrel 2 is vacuum-adsorbed by the pneumatic module, and the servo motor drives the winding mandrel to wind the air curtain once.

[0053] S5. The tape-applying mechanism moves on the displacement module to the side and below the air curtain to apply the tape.

[0054] S6. When the tape head is attached to the air curtain 1, both the tape attaching mechanism and the air curtain winding mechanism move upward to the throat of the clamping winding mechanism 7, that is, to the opening of the clamping winding mechanism 7. The clamping winding mechanism 7 closes, the motor works, and drives the synchronous belt to work. The air curtain reverses under the drive of the synchronous belt 74. The air curtain head is wound on the winding mandrel, and the tape winding is completed at the same time, thus completing the air curtain winding.

[0055] S7. After completion, the wound air curtain can be removed from the mandrel by disassembling the mandrel.
