[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0040] Secondly, the term "embodiment" as used herein refers to specific features, structures, or characteristics that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.
[0041] Example
[0042] Reference Figure 1 and Figure 4This embodiment provides an airbag sewing device, comprising a workbench 1, an XZ-axis robot 2 disposed on the workbench 1, and a hard plastic pad 3 placed on the workbench 1. The end of the XZ-axis robot 2 is a moving base 4, and the moving base 4 is provided with a clamping mechanism 5; the clamping mechanism 5 includes:
[0043] A support plate 51 is fixed to one side of the movable base 4;
[0044] The sliding plate 52 slides on the moving base 4 in the vertical direction. More specifically, an optical axis is provided on both sides of the moving base 4, and linear bearings are provided on both sides of the sliding plate 52 to be slidably connected to the optical axis.
[0045] A plurality of pressing assemblies 53 are located above the support plate 51 and are evenly distributed on the sliding plate 52; the end of the hard plastic pad 3 is clamped by the pressing assemblies 53 and the support plate 51;
[0046] In order to make the lifting amount of both sides of the sliding plate 52 consistent, a plurality of driving assemblies 54 are arranged side by side; the driving assemblies 54 are used to drive the sliding plate 52 to move up and down;
[0047] The power assembly 55 is used to drive the driving assembly 54 to move;
[0048] The specific working process of this device is as follows: first, fix the airbag cloth on the hard plastic pad 3, then manually push the hard plastic pad 3 so that one end is between the support plate 51 and the clamping component 53, then operate the power component 55 to activate the drive component 54, and the drive component 54 moves the sliding plate 52 and the clamping component 53 downward to clamp the hard plastic pad 3. The power component 55 has only one power, which greatly reduces the number of power and reduces the cost of use; after the end of the hard plastic pad 3 is firmly clamped, the XZ-axis robot 2 controls the movement of the airbag cloth according to the preset path, and cooperates with the automatic sewing equipment (not shown) to perform precise sewing.
[0049] Reference Figure 2 and Figure 5 As a preferred solution of the present invention, the drive assembly 54 includes:
[0050] The fixed plate 541 is fixed to the side of the sliding plate 52; the fixed plate 541 is provided with a long hole 1;
[0051] The rotating shaft 542 is rotatably mounted on the movable base 4;
[0052] The driving rod 543 has one end fixed on the rotating shaft 542 and the other end fixed with a fixed shaft 544; the fixed shaft 544 passes through the long hole 1;
[0053] One end of the swing arm 545 is fixed on the rotating shaft 542. Figure 5As shown, the end of the swing arm 545 away from the rotating shaft 542 is tilted upward;
[0054] The specific working process of the driving component 54 is as follows: when the sliding plate 52 needs to be raised or lowered, the driving component 54 is operated to make the swing arms 545 rotate synchronously. Since the rotating shaft 542 is fixedly connected to the driving rod 543 and the swing arm 545, the driving rods 543 are driven to rotate synchronously. Since the fixed shaft 544 passes through the long hole 1 on the fixed plate 541, the sliding plate 52, the clamping component 53, etc. slide along the optical axis, thereby controlling the lifting and lowering of the sliding plate 52 and the clamping component 53.
[0055] If each driving assembly 54 is provided with a power to rotate the swing arm 545, it will cause the problem of increased power, referring to Figure 2 and Figure 5 As a preferred solution of the present invention, the power assembly 55 includes:
[0056] The power mechanism 551 is fixed on the movable base 4. The power mechanism 551 can be a pneumatic cylinder, an oil cylinder or an electric telescopic rod. The output end of the power mechanism 551 is provided with a driving shaft 552.
[0057] The other end of each swing arm 545 is rotatably connected to the connecting rod 553; the connecting rod 553 is provided with a second elongated hole;
[0058] Among them, the driving shaft 552 passes through the second long hole;
[0059] The specific working process of the power assembly 55 is as follows: Figure 2 and Figure 5 As shown, the other end of each swing arm 545 is rotatably connected to the connecting rod 553, and the swing arm 545, the connecting rod 553 and the rotating shaft 542 form a parallelogram connecting rod structure. When the power mechanism 551 drives the driving shaft 552 to rise and fall, since the driving shaft 552 passes through the second long hole, it can drive the connecting rod 553 to move, and due to the existence of the swing arm 545, the connecting rod 553 has horizontal and vertical displacements, so that the rotating shaft 542 of each driving component 54 rotates synchronously, and the two sides of the sliding plate 52 are lifted and lowered synchronously, thereby improving the lifting stability of both sides.
[0060] If the fixed shaft 544 directly contacts the outer wall of the long hole 1, a large friction force will be generated when the driving rod 543 rotates, and long-term operation will cause the fixed shaft 544 and the long hole 1 to wear more severely. As a preferred solution of the present invention, refer to Figure 2 , the drive assembly 54 further includes:
[0061] Bearing 1 is fixed on the fixed shaft 544; the outer wall of bearing 1 is tangent to the outer wall of the elongated hole 1;
[0062] By setting the bearing, the direct metal contact between components is reduced, the wear rate is reduced, and the overall service life of the equipment is extended.
[0063] Since the connecting rod 553 has a horizontal displacement, the pushing shaft 552 and the connecting rod 553 are relatively displaced, which will cause wear and tear after long-term use. Figure 2 , the power assembly 55 further includes:
[0064] Bearing 2 is fixed on the driving shaft 552; the outer wall of bearing 2 is tangent to the outer wall of the second elongated hole;
[0065] By setting up the bearing II, the wear rate is reduced and the overall service life of the equipment is extended.
[0066] As a preferred embodiment of the present invention, refer to Figure 2 The pressing assembly 53 includes a pressing plate 531 and an intermediate plate 532 fixedly connected to the pressing plate 531. The intermediate plate 532 is fixedly connected to the sliding plate 52. More specifically, the cross-sectional area of the intermediate plate 532 is smaller than that of the pressing plate 531. This can save material, increase the contact area with the hard plastic pad 3, and improve the fastening effect.
[0067] A buffer member 533 is installed at the bottom of the pressing plate 531. The buffer member 533 can be made of rubber, polyurethane, silicone, etc. When clamping the hard plastic pad 3, the buffer member 533 directly contacts it, which can effectively clamp the hard plastic pad 3 and protect the hard plastic pad 3 from damage.
[0068] Reference Figure 6 A pressure sensor 534 is provided on one of the buffer members 533 . More specifically, the pressure sensor 534 is embedded in the buffer member 533 , and the pressure sensor 534 is electrically connected to the power mechanism 551 .
[0069] The specific working process of the clamping assembly 53 is as follows: operate the power mechanism 551 to activate the driving assembly 54, and through the linkage of the swing arm 545, the rotating shaft 542 and the driving rod 543, drive the sliding plate 52 and the clamping assembly 53 thereon to move downward, and the buffer member 533 directly contacts the hard plastic pad 3 and begins to apply clamping force. The pressure sensor 534 monitors the clamping force in real time and feeds back the data to the power mechanism 551. The power mechanism 551 automatically adjusts the clamping force according to the set pressure value to ensure that the hard plastic pad 3 can be effectively clamped without causing damage to it.
[0070] If the airbag cloth is placed directly on the hard plastic pad 3, it is very likely to be misplaced during sewing. As a preferred embodiment of the present invention, refer to Figure 1The hard plastic pad 3 is provided with a positioning pin 6, and there are multiple positioning pins 6, and their positions are set according to the shape of the airbag to be sewn. The positioning pins 6 are used to fix the airbag cloth to prevent it from shifting during the sewing process.
[0071] If the end of the support plate 51 away from the movable seat 4 and the end of the hard plastic pad 3 toward the support plate 51 are both vertical surfaces, when the hard plastic pad 3 is pushed, the two will collide, and the hard plastic pad 3 cannot slide quickly onto the support plate 51. As a preferred solution of the present invention, refer to Figure 3 The support plate 51 is tilted toward the bottom at one end away from the moving seat 4, and the tilt angle is less than 30°, and the hard plastic pad 3 is tilted toward the top at one end toward the support plate 51. The tilted design of the two allows the hard plastic pad 3 to naturally slide upward along the inclined surface during the pushing process, making it easier to slide to the support plate 51, reducing the difficulty and time of operation.
[0072] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
