Description

Technical Field

[0001] This invention belongs to the field of automotive interior inlay injection molding technology, specifically relating to a molding equipment for automatic layering and reciprocating bending of dashboard fabric hinges. Background Technology

[0002] Currently, many vehicle manufacturers use high-strength, highly flexible mesh fabrics to make airbag box hinges. To achieve fully automated injection molding of mesh airbag box fabric hinges, the primary task is to solve the problem of automatic layering of the fabric hinges. However, mesh fabric hinges have a multi-mesh structure, and traditional suction cups, air needles, and non-contact suction cups cannot meet the requirements for automatic layering.

[0003] With the increase in passenger-side airbag capacity, some vehicle dashboard airbags now utilize fabric hinges with woven or double-layered sewn functional areas as the airbag deployment hinges. However, due to the complexity of these two fabric hinge molding processes, some projects are gradually adopting a new fabric hinge molding process to replace this production method. This new process uses fabric hinges without functional areas as raw materials, which are then cut or punched, heated and bent, and finally injection molded in segments to form the airbag deployment buffer area. This process significantly improves the consistency and reliability of airbag deployment. However, this new inlay injection molding production method places high demands on the bending of the fabric hinges and the structure of the injection mold.

[0004] Traditional airbag box fabric hinge bending mechanisms are relatively simple, mostly consisting of a single bend, and the requirements for the bending angle are not high. However, the new inlay injection molding process places higher demands on the bending position, bending angle, and number of bends of the fabric hinge, and traditional fabric hinge bending devices can no longer meet the requirements of the new process.

[0005] In summary, the automation level of traditional instrument panel fabric hinge layering and bending is low, and the current inlay injection molding production method cannot meet the needs of existing hinge layering and bending. Summary of the Invention

A Y-axis positioning cylinder assembly 23 is provided on the cylinder connecting plate 24 between the fabric hinge positioning plate 21 and the cylinder connecting plate 24. A junction box 26 is fixed below the quick-change upper plate 25 and is used to interface the input signals from the cylinder magnetic switch or other sensors with the multi-needle signals on the pneumatic quick-change assembly 27. The pneumatic quick-change assembly 27 allows for quick replacement of fabric hinge positioning assemblies for different products, as set on the positioning support 28, enabling rapid switching between different fabric hinges. Once the male and female heads of the pneumatic quick-change assembly 27 are aligned, the pneumatic, electrical, and mechanical structures are connected.

[0054] like Figure 7-8As shown, the fabric hinge clamping and bending assembly 3 includes a base, a pneumatic quick-change 31, a photoelectric switch 32, a pneumatic finger 33, a lower insert 34, a lower insert cylinder 35, a fabric hinge bending support frame 36, a fabric hinge support plate 37, and a support plate cylinder 38. The lower insert cylinder 35 and the photoelectric switch 32 (which is connected to a junction box fixed on the fabric hinge bending support frame 36) are both fixed inside the fabric hinge bending support frame 36. The lower insert 34 is connected to the telescopic flange plate of the lower insert cylinder 35. (The top plate of the fabric hinge bending support frame 36 is narrower than the bottom plate; therefore, when the lower insert cylinder 35 is fixed to the bottom plate, the lower insert 34 installed on its top telescopic flange plate...) Located above the bottom plate on the right side of the top plate, allowing the lower insert 34 to move under the drive of the lower insert cylinder 35, the fabric hinge bending support frame 36 has pneumatic fingers 33 (MGS: PUF20-90) fixed to the outer sides of both ends in the length direction.

The finger mounting plate 45 is connected to the telescopic end of the main pressing cylinder 44, allowing the finger mounting plate 45 to move up and down under the action of the main pressing cylinder 44. During the fabric hinge bending process, since bending requires significant pressure, relying solely on the pressure of the main pressing cylinder 44 will lead to over-bending. During the process, the main pressing cylinder 44 rebounds, affecting the bending effect. Therefore, multiple auxiliary pressing cylinders 48 need to be designed to cooperate with the pressing. On both sides of the finger mounting plate 45 along its length, multiple fabric hinges are provided to grip the fingers 47. The upper insert cylinder 410 is fixed to the finger mounting plate 45 through a connecting plate.

The rotational motion of the servo motor drives the slider base to reciprocate linearly back and forth. The linear module assembly 6 is mounted on the bottom support frame 1, and a vertical plate is mounted above its drive slider. A quick-change mounting plate for mounting quick-change male connectors is mounted above the vertical plate. The quick-change male connectors are fixed on the quick-change mounting plate. The bottom of the main pressure cylinder mounting plate 42 is connected to the quick-change male connectors via a pneumatic quick-change female connector 43.

The proximity switch 17 is fixed to the second stop block 124.

[0077] The process of using this invention:

[0078] In use, the position of the first fabric hinge positioning component 91 relative to the lifting tray 81 is first adjusted by moving the first fabric hinge positioning component 91 back and forth on the transverse slide rail 121. Then, the left and right positions of the second fabric hinge positioning component 92 on the fixed plate 7 are adjusted to accommodate changes in the size of the fabric hinge placed on the lifting tray 81. The first stop 123 and the second stop 124 limit the movement of the first fabric hinge positioning component 91. The proximity switch 17 located on the second stop 124 is used to monitor the position of the first fabric hinge positioning component 91.

[0079] Rotating cylinder 101 rotates, which in turn drives transverse guide rod cylinder 102 and longitudinal guide rod cylinder 103 to rotate to the left or right, fully exposing the fabric hinge positioning mechanism 9 above, making it convenient to place the fabric hinge on the lifting tray 81. After the fabric hinge is placed, rotating cylinder 101 rotates in the opposite direction, which in turn drives transverse guide rod cylinder 102 and longitudinal guide rod cylinder 103 to rotate in the opposite direction, so that the inclined top rod 1010 below the top rod mounting plate 109 is located above the fabric hinge.

[0080] The servo motor 821 of the screw jack platform 82 operates, driving the worm gear to rotate via its output shaft. This causes the screw to move upward within the worm gear, which in turn causes the flange to move the lifting pallet 81 upward until it reaches below the tilting rod 1010. The upper limit detection switch 18 and the lower limit detection switch 19 of the lifting pallet are used to monitor the upper and lower limit positions of the lifting pallet 81. The position of the fabric hinge on the lifting pallet 81 is monitored by the fabric hinge detection switch 15. The tilting rod 1010 can only touch the fabric hinge when it reaches this position. The upper limit detection switch 14 of the fabric hinge monitors the upper limit position of the fabric hinge; the top of the fabric hinge cannot exceed this position.

[0081] The longitudinal guide rod cylinder 103 extends, driving the lower push plate 104 to move downward, so that the end of the inclined push rod 1010 contacts the fabric hinge. The transverse guide rod cylinder 102 extends, driving the longitudinal guide rod cylinder 103 to move backward, so that the end of the inclined push rod 1010 pushes the fabric hinge backward, causing the uppermost fabric hinge to form an arch. Then, the uppermost fabric hinge is grasped by the pneumatic fingers or other gripping mechanisms distributed on both sides of the arched fabric hinge, thereby realizing the layering of the fabric hinge.

[0082] When the fabric hinge photoelectric detection switch 16 detects that there is no fabric hinge on the lifting pallet 81, it means that all fabric hinges have been completed in layers. The servo motor 821 of the screw lifting platform 82 then operates, driving the worm gear to rotate through the output shaft of the servo motor 821. This causes the screw to move downward within the worm gear, and the zero-point switch 13 monitors the downward position of the flange on the screw until the lifting pallet 81 falls into the required designated position, preparing for the next loading.

[0083] Next, place the captured airbag fabric hinge on the fabric hinge positioning plate 21 between the X-axis cylinder positioning bracket and the Y-axis cylinder positioning bracket. Then, activate the X-axis cylinder of the X-axis positioning cylinder assembly 22 and the Y-axis cylinder of the Y-axis positioning cylinder assembly 23, so that they drive the X-axis cylinder positioning bracket and the Y-axis cylinder positioning bracket to push the airbag fabric hinge on the fabric hinge positioning plate 21 through the X-axis cylinder connecting plate and the Y-axis cylinder connecting plate, so that it is positioned at the required position on the fabric hinge positioning plate 21. The X-axis cylinder positioning bracket and the Y-axis cylinder positioning bracket limit the airbag fabric hinge in the X and Y directions.

[0084] The linear module 6 drives the fabric hinge gripping and bending component 4 to move back and forth between the fabric hinge positioning component 2 and the fabric hinge clamping and bending component 3 to realize the transport of the fabric hinge. First, the linear module 6 drives the fabric hinge gripping and bending component 4 to move, so that the fabric hinge gripping and bending component 4 is located above the airbag fabric hinge on the fabric hinge positioning plate 21 of the fabric hinge positioning component 2.

[0085] Driven by the main pressing cylinder 44, the finger mounting plate 45 moves downward, so that the fabric hinge gripping finger 47 is positioned above the airbag fabric hinge, opening the fabric hinge gripping finger 47 to grip the airbag fabric hinge, and limiting the airbag fabric hinge through the fabric hinge clamping limit block 46. Driven in the opposite direction by the main pressing cylinder 44, the finger mounting plate 45 moves upward, so that the airbag fabric hinge gripped by the fabric hinge gripping finger 47 leaves the fabric hinge positioning plate 21.

[0086] The linear module assembly 6 drives the fabric hinge gripping and bending assembly 4 to above the fabric hinge clamping and bending assembly 3. Under the drive of the main pressing cylinder 44, the finger mounting plate 45 moves downward. When the finger mounting plate 45 is lowered to the position, the pneumatic finger 33 clamps the airbag fabric hinge. Then, the fabric hinge gripping finger 47 is released, and the airbag fabric hinge is placed at the required position on the top surface of the fabric hinge bending support frame 36. Then, the extension end of the support plate cylinder 38 drives the fabric hinge support plate 37 to move upward, so that the fabric hinge support plate 37 supports the airbag fabric hinge.

[0087] At this time, the heating plate extension cylinder 55 drives the heating plate 52 forward until it is positioned above the fabric hinge on the fabric hinge bending support frame 36 and fabric hinge support plate 37. Then, the heating plate pressing cylinder 54 drives the heating plate 52 downward along the guide rod 53, causing the lower end face of the heating plate 52 to fully contact the fabric hinge. Thermocouple 56 inside the heating plate 52 is used to monitor the heating plate temperature. Only when the current temperature of the heating plate 52 meets the preset temperature can the heating plate extension cylinder 55 drive the heating plate 52 forward. After heating is completed, the control... The heating plate pressing cylinder 54 reverses direction, causing the heating plate 52 to move upward along the guide rod 53 without contacting the fabric hinge. Then, the heating plate extending cylinder 55 controls the heating plate 52 to move backward, removing it from above the fabric hinge. Next, the extension end of the support plate cylinder 38 causes the fabric hinge support plate 37 to move downward. The main pressing cylinder 44 causes the finger mounting plate 45, upper insert cylinder 410, and upper insert 49 below it to move downward. When the main pressing cylinder 44 extends to its position, the auxiliary pressing cylinder 48 extends to provide auxiliary pressing to the finger mounting plate 45. Subsequently, the upper insert cylinder 410 and lower insert cylinder 35 cause the upper insert 49 and lower insert 34 to extend sequentially, bending the fabric hinge. After bending, the insert cylinder causes the insert to move in the opposite direction, returning to its initial state.

[0088] Finally, the main pressing cylinder 44 and the auxiliary pressing cylinder 48 retract in the opposite direction, the pneumatic finger 33 is released, and the linear module assembly 6 drives the fabric hinge gripping and bending assembly 4 to move away from above the fabric hinge clamping and bending assembly 3, in preparation for the next cycle.
