Description

Technical Field

[0001] This invention belongs to the field of high-frequency welding technology, and particularly relates to a high-frequency welding device for air bags. Background Technology

[0002] Automotive adjustable airbags are airbags placed in car seats. They inflate and deflate to adjust the seat support and provide a massage effect when needed. Currently, automotive adjustable airbags use a bag-like structure, specifically welded together from two square membranes and an air tube inserted between them. The current production process involves cutting the membranes and air tubes before welding. The membranes are cut into blocks, and then the air tubes are welded between the two membranes using a welding machine with an air tube welding mold. Finally, another welding machine with a bladder body welding mold seals the two membranes. This production system has many transfer and alignment steps, resulting in a long average production time for airbags and significantly impacting output.

[0003] To overcome the aforementioned technical problems, Chinese utility model patent document CN221437268U discloses a vehicle adjustable airbag production system, comprising: an airbag film delivery mechanism adapted to continuously output two films in a bonded state; an air tube insertion mechanism adapted to insert an air tube into the two suspended films, and after the air tube welding mechanism welds the corresponding part of the air tube to the film, it withdraws from the two films for the next insertion; a sealing mechanism adapted to weld the corresponding part of the film around each air tube to seal the airbag body; and a cutting mechanism adapted to cut the sealed airbag body from the continuous film. The air tube insertion mechanism includes: a linear module facing the film delivered from the film outlet; an air tube limiting component disposed on the slide of the linear module; an air tube positioning component disposed in front of the air tube limiting component; and an air tube guiding component disposed on the slide and extending in front of the air tube positioning component. The trachea positioning assembly includes: a positioning gripper, positioned in front of the trachea limiting assembly, with a positioning groove on one of its grippers; and a trachea shear, positioned in front of the positioning gripper. The trachea limiting assembly includes: a rear gripper, positioned on a slide; a pair of limiting rods, positioned on one of the rear grippers with a spacing adapted to the outer diameter of the trachea; and a limiting rod through-hole on the other gripper that matches the pair of limiting rods. The limiting rods are adapted to pass through the corresponding limiting rod through-holes to form trachea perforations, and the trachea perforations are aligned with the positioning grooves. The trachea guiding assembly includes: a separation drive, positioned on the slide; an extension rod, positioned on the separation drive, with its front end extending in front of the trachea shear; a trachea insertion rod, connected to the front end of the extension rod, facing the positioning groove and aligned with it; and a pointed separating piece, its tail covering the front end of the extension rod, with its pointed end facing the two membranes that are paused for delivery. The trachea welding machine is a high-frequency welding machine.

[0004] First, manually thread the trachea through the trachea perforation hole and insert the front end of the trachea into the positioning groove. After startup, the positioning jaws clamp the trachea, and then the slide table moves towards the positioning jaws with the trachea insertion rod until the trachea insertion rod is inserted into the trachea. The rear jaws also move with the slide table. After the trachea insertion rod is inserted into the trachea, the rear jaws close and clamp the trachea. The positioning jaws release the trachea, and the slide table moves forward a certain distance according to the preset path to pull out a certain length of trachea. The positioning jaws then clamp the trachea again, and the trachea shears cut the trachea. The rear jaws then release the trachea again, and the slide table, along with the rear jaws, trachea insertion rod, and trachea, moves towards the two membranes that are being paused. The pointed tip of the deflector first pierces into the two membranes. The two membranes are separated to allow the endotracheal tube insert to be inserted between them. After the endotracheal tube insert is inserted, the front end of the endotracheal tube on the insert is also inserted into the membrane, allowing for welding of the membrane and the endotracheal tube. At this time, the rear end gripper is positioned close to the positioning gripper. The separation drive pushes the extension rod forward after welding, separating the endotracheal tube insert from the welded endotracheal tube. When the two membranes resume conveying, the welded endotracheal tube moves with the two membranes, creating space for the front end of the extension rod, the endotracheal tube insert, and the pointed separating plate to exit. The slide then drives the rear end gripper and the extension rod to reset for the next insertion. The above process completes the welding of a section of air tube in a membrane area with a welding mark as the base point. The membrane area with the welding mark as the base point then enters the welding position of the airbag sealing welding machine according to the above process. The airbag sealing welding machine welds the corresponding part of the membrane around the air tube to seal the airbag, thereby obtaining a vehicle adjustable airbag. At this time, the vehicle adjustable airbag is still in the membrane. Then, it enters the stamping position of the stamping machine according to the above process, and can be cut out from the membrane. The cut vehicle adjustable airbag can be grabbed out by the airbag clamp, and the excess material generated during cutting can be grabbed out by the cutting clamp.

[0005] In the technical solution disclosed in the aforementioned patent documents, a tracheal insertion rod is inserted into the trachea to position the trachea. Then, the rear-end grippers close and clamp the trachea. The positioning grippers release the trachea, and the slide moves forward a certain distance according to a preset time to pull out a certain length of trachea. The positioning grippers then clamp the trachea again, and the trachea shears cut the trachea. The rear-end grippers then release the trachea. The slide, carrying the rear-end grippers, the tracheal insertion rod, and the trachea, moves towards the two membranes that are temporarily suspended. Its structure is relatively complex, and the trachea generates heat during the welding process. Since heat dissipation is inconvenient during trachea welding, it can cause problems such as softening and deformation of the trachea. Summary of the Invention

[0017] The above-mentioned one or more technical solutions in the air bag high-frequency welding equipment provided in the embodiments of the present invention have at least the following technical effects: The first set of film rolls is positioned on the first support shaft, and its free end passes through the first traction roller assembly and the support roller, then through the gap formed by the first welding mold and the second welding mold, as well as the gap formed by the upper welding mold and the lower welding mold, and finally connects to the stepping traction device.

After the air pipe and membrane are welded, the stepping traction device pulls and transports the membrane, with the welded air pipe positioned between the upper and lower welding molds. Under the action of the third lifting drive mechanism, the upper welding mold presses the membrane firmly onto the lower welding mold, thus completing the welding and separation of the upper and lower membranes.

[0031] Reference Figure 1 and Figure 3 The air delivery device 400 is located on one side of the first high-frequency welding device 300. The air delivery device 400 includes a fixed base 410, a first translation mechanism 420, a clamping member 430, a shearing assembly 440, a second translation mechanism 450, and a metal air pipe 460. The fixed base 410 is mounted on the frame 200, and the shearing assembly 440 is mounted on the fixed base 410. The shearing assembly 440 includes a translation cylinder 441 and pneumatic scissors 442 mounted on the translation cylinder 441.

Preferably, the clamping member 430 is a pneumatic parallel clamp, and the first translation mechanism 420 and the second translation mechanism 450 are electric lead screw linear modules.

[0032] Reference Figure 1 and Figure 4 A second high-frequency welding device 500 is mounted on the frame 200 and is used to weld and cut the edges of the air bag, allowing the formed air bag to be separated from the main body of the film. The second high-frequency welding device 500 includes a base 510, a mounting frame 520, a third lifting drive 530, an upper welding mold 540, and a lower welding mold 550.

[0033] Reference Figure 1 The stepping traction device 600 is mounted on the frame 200 and is used to traction the film at equal intervals, so that the film can be transported at equal intervals.

[0034] In this embodiment of the high-frequency welding equipment for air bags, a feeding device 100 transports vertically distributed films between a first welding mold 340 and a second welding mold 350. An air tube is then welded between the two films. During welding, a clamping member 430 clamps and moves the free end of the air tube, allowing the end of the air tube to fit onto a metal air tube 460, which positions the air tube to be welded. After the air tube is pulled out to a certain length, a cutting component cuts the air tube. Then, a first translation mechanism 420 and a second translation mechanism 450 simultaneously drive the clamping member 430 and the metal air tube 460 to move, positioning the cut air tube between the first welding mold 340 and the second welding mold 350. One end of the air tube passes through the two layers of films and extends outwards; this simplifies the overall structure of air tube positioning and transport. The first lifting drive component 320 drives the first welding mold 340 to descend, and the second lifting drive component 330 drives the second welding mold 350 to rise. Under the action of the high-frequency control system, the first welding mold 340 and the second welding mold 350 weld the air pipe to the upper and lower films. During the welding process, the air blowing system blows air into the metal air pipe 460 to dissipate heat and cool the air pipe, preventing it from softening and deforming due to high temperature. After the air pipe and film are welded, the stepping traction device 600 pulls and transports the film, and the position where the air pipe is welded is located between the upper welding mold 540 and the lower welding mold 550. Under the action of the third lifting drive mechanism 530, the upper welding mold 540 presses the film tightly onto the lower welding mold 550, thereby completing the welding and separation of the upper and lower films.

[0035] Furthermore, refer to Figure 2 The feeding device 100 also includes a first dynamic moving mechanism 170 and a second dynamic moving mechanism 180 arranged parallel to each other.

In this embodiment, the first dynamic moving mechanism 170 and the second dynamic moving mechanism 180 dynamically adjust the positions of the first support shaft 120 and the second support shaft 130 to achieve the effect of correcting the film deviation and preventing the two films from misaligning.

[0036] Furthermore, refer to Figure 1 and Figure 2 The first dynamic moving mechanism 170 includes a first electric cylinder. The first electric cylinder has a first connecting part 172 at both ends.

Specifically, in this embodiment, because the ends of the first and second electric cylinders are hinged, dynamic adjustment can be achieved even if the installation heights are different, avoiding the problem of jamming.

[0038] Furthermore, refer to Figure 3 The moving end of the second translation mechanism 450 is also provided with a partition 451, which is used to separate the upper and lower films. A mounting portion 452 extends from the free end sidewall of the partition 451, and a metal air pipe 460 is disposed on the mounting portion 452.

[0041] Furthermore, refer to Figure 3 The mounting base 410 is also provided with a guide hole 411 through which an air pipe passes. The air pipe to be welded passes through the guide hole 411 and extends out, which guides and limits the air pipe, making it easier for the cutting component 440 to cut the air pipe.

[0042] Furthermore, refer to Figure 1 , Figure 4 and Figure 5The stepping traction device 600 includes two sets of belt transmission mechanisms, and the second high-frequency welding device 500 is located between the two belt transmission mechanisms. The belt transmission mechanism includes two belt rollers 610, a transmission belt 620, a linear motion module 630, a translation seat 640, and a pressing mechanism 650. The frame 200 has two mounting positions, with the two belt rollers 610 respectively located at the corresponding mounting positions. The transmission belt 620 is wound around the two belt rollers 610. The linear motion module 630 is located on the bottom side of the transmission belt 620, and the translation seat 640 is located on the linear motion module 630. The translation seat 640 has a pad 641 extending between the upper and lower layers of the transmission belt 620.

The pressing mechanism 650 is a cylinder, and the bottom of the cylinder has a pressure block. In this embodiment, the film output from the first high-frequency welding device 300 can be supported on the first set of belt conveyor mechanisms. The pressing mechanism 650 presses the film and the upper conveyor belt 620 tightly onto the pad 641. The linear motion module 630 then drives the translation seat 640 to move, thereby transporting the film equidistantly to the second high-frequency welding device 500. The film output from the second high-frequency welding device 500 can be equidistantly pulled by another set of belt conveyor mechanisms.

[0043] Furthermore, refer to Figure 1 and Figure 5 Above the belt conveyor mechanism near the output end of the second high-frequency welding device 500, there is also a material handling robot 700, which is used to pick up the formed air bags and realize automatic material unloading.

[0044] Furthermore, refer to Figure 5 The picking robot 700 includes a mounting frame 710, a translation cylinder assembly 720, a suction assembly 730, and a pressing cylinder assembly 740. The mounting frame 710 is positioned above the belt conveyor mechanism, the translation cylinder assembly 720 is located at the upper end of the mounting frame 710, and the suction assembly 730 is located at the moving end of the translation cylinder assembly 720. A mounting beam 711 is located on one side of the mounting frame 710, and both the mounting beam 711 and one side of the mounting frame 710 are equipped with pressing cylinder assemblies 740. In this embodiment, when picking up a welded air bag, the two sets of pressing cylinder assemblies 740 press the edge of the film tightly onto the conveyor belt 620, and the suction assembly 730 sucks up the air bag and lifts it upwards, separating the air bag from the overall film.

[0045] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
