[0023] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of an automatic riveting production device for an airbag retaining ring of the present invention in conjunction with the accompanying drawings.
[0024] Figure 1 The structure of an automatic riveting production device 100 for an airbag retaining ring 4 according to an embodiment of the present invention is shown. Figure 2 FIG. 2 shows a schematic diagram of the connection structure between the feeding device 1 and the screening device 2 according to an embodiment of the present invention. Figure 1 and Figure 2 As shown, the automatic riveting production equipment 100 includes a conveying direction (such as Figure 1 B direction as shown in the figure): a feeding device 1, a screening device 2 and an automatic riveting mechanism 3 are sequentially arranged. Among them, a material taking device 31 is provided on the automatic riveting mechanism 3, and the feeding device 1 is arranged to be able to feed the airbag retaining rings 4 one by one and continuously into the screening device 2, and the screening device 2 is arranged to be able to adjust the placement directions of the airbag retaining rings 4 entering therein to be consistent, and the automatic riveting mechanism 3 is arranged to be able to take the adjusted airbag retaining rings 4 into the automatic riveting mechanism 3 through the material taking device 31 for riveting.
[0025] When the automatic riveting production equipment 100 for the airbag retaining ring 4 of the embodiment of the present invention is used, the airbag retaining ring 4 is placed in the feeding device 1. Since the screw riveting position of the airbag retaining ring 4 needs to be changed according to different vehicle models, when the automatic riveting production equipment 100 of the embodiment of the present invention starts working, the feeding device 1 first feeds the airbag retaining ring 4 one by one and continuously into the screening device 2, so that the screening device 2 can adjust the placement direction of the airbag retaining ring 4 to be consistent, so that the airbag retaining rings 4 of the same batch can have the same placement direction or shape. The airbag retaining ring 4 with adjusted placement direction or shape is transported to the material taking device 31 of the automatic riveting mechanism 3 through the screening device 2, and the material taking device 31 takes the material. Since the airbag retaining ring 4 arriving at the material taking device 31 has a uniform shape, the automatic riveting mechanism 3 can directly take the airbag retaining ring 4 through the material taking device 31 and rivet it into shape.
[0026] It should be noted that the placement direction of the airbag retaining ring 4 adjusted by the material screening device 2 should be understood as follows: after the automatic riveting mechanism 3 takes the airbag retaining ring 4 through the material taking device 31 and places it at the processing position, the riveting position of the airbag retaining ring 4 just corresponds to the position of the riveting machine on the automatic riveting mechanism 3. Specifically, it can be adjusted according to the actual processing direction.
[0027] Through the above-mentioned arrangement, the automatic riveting production equipment 100 for the airbag retaining ring 4 of the embodiment of the present invention can realize the automation of the entire riveting process of the airbag retaining ring 4, that is, the entire process from feeding, screening and riveting can be completed by the equipment itself. In this way, not only the production efficiency of the airbag retaining ring 4 can be improved, but the automated production also saves labor costs, thereby not only reducing the production cost of the enterprise, but also effectively avoiding the potential safety hazards during manual operation, thereby bringing better beneficial effects to the enterprise.
[0028] In such Figure 1 In the preferred embodiment shown, the automatic riveting mechanism 3 may include: a rotating platform 32, the rotating platform 32 is provided with a plurality of processing positions 321 along its rotation center; and a material taking device 31, a riveting device 33 and a length detection device (not shown in the figure) arranged on the outer side of the edge of the rotating platform 32 in sequence around the rotating platform 32. In the working state of the automatic riveting mechanism 3, the rotating platform 32 can rotate to sequentially position the processing position 321 below the material taking device 31, the riveting device 33 and the length detection device, and finally return to the material taking device 31. The material taking device 31 is configured to take the airbag retaining ring 4 adjusted by the screening device 2, and to take the airbag retaining ring 4 detected by the length detection device to an external finished product bin. The riveting device 33 is configured to rivet the airbag retaining ring 4 placed on the processing position 321 by the material taking device 31. The length detection device is configured to detect the length of the screws of the airbag retaining ring 4 after the press riveting, so as to ensure the yield rate of the airbag retaining ring 4 after the press riveting.
[0029] In such Figure 3 In the preferred embodiment shown, the feeding device 1 may include: a material box 11 for containing the airbag retaining ring 4; a conveying platform 12 connected to the feeding port of the screening device 2; and a pushing mechanism 13 located below the conveying platform 12. The discharge port of the material box 11 is connected to the pushing mechanism 13, so that the airbag retaining ring 4 can be continuously in contact with the pushing mechanism 13, and the pushing mechanism 13 can be used to continuously push the airbag retaining ring 4 in the material box 11 from bottom to top onto the conveying platform 12, and the conveying platform 12 is configured to drive the airbag retaining ring 4 to move, so as to convey the airbag retaining ring 4 to the screening device 2.
[0030] Through the above arrangement, when the feeding device 1 is used, the airbag retaining ring 4 is first placed in the material box 11, and at least half of the space of the material box 11 is filled, so that the airbag retaining ring 4 can continuously contact the pushing mechanism 13 through the discharge port of the material box 11. When the feeding device 1 starts feeding, the pushing mechanism 13 can push the airbag retaining ring 4 from bottom to top onto the conveying table 12, and convey the airbag retaining ring 4 to the outside through the conveying table 12. In this way, especially when a large number of airbag retaining rings 4 are processed in a processing plant, the feeding device 1 of the embodiment of the present invention can replace manual feeding, and the operator only needs to place the airbag retaining ring 4 to be processed in the material box 11. Therefore, not only the labor cost is directly reduced, but also the feeding efficiency can be improved by controlling the pushing mechanism 13, thereby effectively improving the production efficiency of the enterprise.
[0031] Preferably, if Figure 3 As shown, the feeding device 1 may further include a base 15, which may include a top surface 151 for fixing the conveying platform 12, a bottom surface 152 opposite to the top surface 151 and connected to a fixed foundation, and a side surface 153 for connecting the top surface 151 and the bottom surface 152, the side surface 153 being configured to be inclined in a direction away from the material box 11, and the pushing mechanism 13 being fixed on the side surface 153. With this arrangement, the pushing mechanism 13 is arranged obliquely on the side surface 153, on the one hand, so that the airbag retaining ring 4 in the material box 11 can better contact with the pushing mechanism 13 by its own gravity, thereby being more conducive to the implementation of pushing by the pushing mechanism 13; on the other hand, the inclined pushing mechanism 13 enables the airbag retaining ring 4 to form a more stable fit with the surface of the pushing mechanism 13 during the pushing process, thereby improving the stability of the pushing of the airbag retaining ring 4 and preventing it from falling.
[0032] In a preferred embodiment, the angle between the side surface 153 and the horizontal plane may range from 30° to 60°. Further effectively, the angle between the side surface 153 and the horizontal plane is 45°.
[0033] In such Figure 3 In the preferred embodiment shown, the pushing mechanism 13 may include a first pushing plate 131 that slidably cooperates with the side surface 153 and a second pushing plate 132 that slidably fits on the first pushing plate 131. The second pushing plate 132 is configured to slide between the bottom and the top of the first pushing plate 131 under the drive of the first driving device, and the first pushing plate 131 is configured to slide between the initial position and the conveying platform 12 under the drive of the second driving device.
[0034] When the pushing mechanism 13 of this embodiment is in use, when the pushing mechanism 13 pushes the material, the airbag retaining ring 4 located on the second pushing plate 132 can slide upward to the top of the first pushing plate 131 through the second pushing plate 132. After the second pushing plate 132 pushes the airbag retaining ring 4 to the top of the first pushing plate 131, the second pushing plate 132 returns to the bottom of the first pushing plate 131 to prepare for the next pushing. After receiving the airbag retaining ring 4 pushed by the second pushing plate 132, the first pushing plate 131 slides upward to push the airbag retaining ring 4 to the conveying platform 12, and then returns to the initial position to wait for the next pushing of the second pushing plate 132. Through this setting, the second pushing plate 132 and the first pushing plate 131 can be used in combination to facilitate filtering of the airbag retaining ring 4 that is not conducive to being delivered to the conveying platform 2. The details can be seen in the following description.
[0035] In a preferred embodiment, the thickness of the first push plate 131 is equal to the thickness of the airbag retaining ring 4, and the thickness of the second push plate 132 is greater than the thickness of the first push plate 131. With this arrangement, during the pushing process of the first push plate 131 and the second push plate 132, since the thickness of the second push plate 132 is greater than the thickness of the first push plate 131, the second push plate 132 can push more airbag retaining rings 4 onto the first push plate 131, and the thickness of the first push plate 131 is set to be equal to the thickness of the airbag retaining ring 4, so that the airbag retaining ring 4 pushed by the second push plate 132 can only be located on the first push plate 131 alone, so that only a single or single-row airbag retaining ring 4 is formed on the first push plate 131, and then after the single or single-row airbag retaining ring 4 is pushed onto the conveying platform 12, the conveying platform 12 can transport the single or single-row airbag retaining ring 4 to the outside. Through this arrangement, when the production of airbag retaining rings 4 needs to be placed individually or in rows for continuous processing or loading, the feeding device 1 of the present invention can be beneficial to the processing or loading in this case, which can not only be more conducive to ensuring the quality of processing of individual airbag retaining rings 4 and the neatness of loading of rows of airbag retaining rings 4, but also replaces manual operation, thereby saving labor costs and the company's production costs.
[0036] It should be noted here that the thickness of the first push plate 131 is equal to the thickness of the airbag retaining ring 4. It should be understood that the thickness of the first push plate 131 is approximately equal to the thickness of the airbag retaining ring 4, that is, the thickness of the first push plate 131 should be slightly larger than the thickness of the airbag retaining ring 4, so that the airbag retaining ring 4 can have a certain tilt margin when on the first push plate 131, thereby making the airbag retaining ring 4 more stable during pushing, thereby ensuring the smooth pushing of the airbag retaining ring 4.
[0037] like Figure 3 In the preferred embodiment shown, the conveying platform 12 may include: a conveying plane 121 disposed on the top surface 151; a linear vibrator 123 fixed on the conveying plane 121 for driving the conveying plane 121; and a butt surface 122 connected to the conveying plane 121 for butting against the airbag retaining ring 4. The conveying plane 121 is configured to be able to drive the airbag retaining ring 4 to slide relative to the butt surface 122 under the drive of the linear vibrator 123. With this configuration, when the pushing mechanism 13 pushes the airbag retaining ring 4 onto the conveying plane 121, the butt surface 122 can effectively butt against the airbag retaining ring 4, so that the airbag retaining ring 4 can maintain the state when pushing. The linear vibrator 123 drives the conveying plane 121 so that the vibration generated by the conveying plane 121 can effectively filter the accumulated airbag retaining rings 4, thereby effectively avoiding the accumulation of the airbag retaining rings 4 on the conveying plane 121, thereby ensuring the neatness of the airbag retaining rings 4 sent to the screening device 2 through the conveying platform 12.
[0038] In such Figure 4 In the preferred embodiment shown, the screening device 2 may include a screen along the moving direction of the airbag retaining ring 4 (eg Figure 4 The feed channel 21 connected to the discharge port of the feeding device 1 and the discharge channel 22 connected to the feed port of the material taking device 31 are connected in sequence (in the B direction shown in the figure): the feed channel 21 connected to the discharge port of the feeding device 1 and the discharge channel 22 connected to the feed port of the material taking device 31, and the inclined surface 23 connected to the feed channel 21 and the discharge channel 22 and inclined relative to the vertical direction. The inclined surface 23 may be formed with a deflection groove 231 (combined with the eccentric protrusion 41 on the airbag retaining ring 4) for hooking Figure 5 As shown in the figure, the airbag retaining ring 4 can move to the inclined surface 23 through the feed channel 21, and can slide down the inclined surface 23 by its own gravity. The eccentric protrusion 41 on the airbag retaining ring 4 can form a hook with the deflection groove 231 and then swing to a consistent direction by its own gravity and enter the discharge channel 22.
[0039] When the screening device 2 is in use, the airbag retaining ring 4 moves to the inclined surface 23 through the feed channel 21. The feed channel 21 drives the airbag retaining ring 4 to move in a manner that can be set as a linear vibration conveyor or other manners, which are not limited here. When the airbag retaining ring 4 moves to the inclined surface 23, the airbag retaining ring 4 slides down the inclined surface under its own gravity. It should be noted here that in order to ensure the uniformity of the processing position of the airbag retaining rings 4 of the same batch, an eccentric protrusion 41 (such as Figure 5As shown in the figure, the airbag retaining ring 4 slides down along the inclined surface 23 by its own gravity so that the eccentric protrusion 41 thereon can form a hook with the deflection groove 231. In this way, due to the eccentric effect of the eccentric protrusion 231, the airbag retaining ring 4 can continue to swing by its own gravity until it reaches a position where the center of gravity is balanced, and then enter the discharge channel 22 and be transported to the material taking device 31. Through this setting, when processing the same batch of airbag retaining rings 4, the screening device 2 of the embodiment of the present invention can make each airbag retaining ring 4 in a unified state of gravity balance through the inclined surface 23 and the deflection groove 231 thereon, that is, adjust each airbag retaining ring 4 to a unified direction. In this way, not only can the placement of the airbag retaining ring 4 be completed by replacing workers, thereby saving labor costs, but also the placement efficiency of the airbag retaining ring 4 can be improved, thereby effectively improving the production efficiency of the enterprise.
[0040] Preferably, if Figure 6 As shown, one end of the deflection groove 231 may be formed with a notch 251 that is connected to the discharge channel 22. This arrangement can facilitate the eccentric protrusion 41 of the airbag retaining ring 4 to be separated from the deflection groove 231, so that the airbag retaining ring 4 can better enter the discharge channel 22 after adjusting the consistent direction, so as to facilitate the discharge channel 22 to transport the airbag retaining ring 4 to the material taking device 31.
[0041] In such Figure 6 In the preferred embodiment shown, the deflection groove 231 may include a linear groove 261 connected to the discharge channel 22 and extending in the horizontal direction, and an arc-shaped groove 271 extending from the end of the linear groove 261 toward the feed channel 21. Through this arrangement, the arc-shaped groove 271 may be formed with a groove section with a large slope, so that after the airbag retaining ring 4 is hooked with the section, the swing speed of the airbag retaining ring 4 can be increased under the action of its own gravity, thereby effectively improving the adjustment efficiency of the direction of the airbag retaining ring 4.
[0042] In such Figure 2 In the preferred embodiment shown, the screening device 2 may also include a translation device 24 connected to the discharge channel 22. The translation device 24 may be configured to transport the airbag retaining ring 4 after the adjustment direction is consistent to the material picking device 31, so as to ensure that the movement of the airbag retaining ring 4 after the adjustment direction is more stable when it is transported to the material picking device 31 for use.
[0043] Back to Figure 1Preferably, a length quality inspection device (not shown in the figure) is also provided in the automatic riveting mechanism 3, and the automatic riveting production equipment 100 may also include: a slideway (not shown in the figure) for connecting the external hopper 5 and the material taking device 31, and an opening (not shown in the figure) can be formed on the slideway to allow the airbag retaining ring 4 to pass through; a cover plate (not shown in the figure) provided at the bottom of the slideway and located at the opening; and a third drive device (not shown in the figure) electrically connected to the length quality inspection device and capable of driving the cover plate to block and open the opening. The third drive device is configured to receive a detection signal from the length quality inspection device, so that when the detection signal reflects that the quality inspection result is qualified, the third drive device drives the cover plate to block the opening, and when the detection signal reflects that the quality inspection result is unqualified, the third drive device drives the cover plate to open the opening.
[0044] As can be seen from the above, the length quality inspection device can detect the length of the screws of the airbag retaining ring 4 after riveting to ensure the yield rate of the airbag retaining ring 4 after riveting. Through this setting, when the third drive device receives the detection signal of the length quality inspection device and the quality inspection result is qualified, the third drive device drives the cover plate to block the opening, and the airbag retaining ring 4 can slide into the external hopper 5 through the slideway for the next step of processing; and when the detection signal reflects that the quality inspection result is unqualified, the third drive device drives the cover plate to open the opening, and the airbag retaining ring 4 falls into the waste hopper through the opening so that it can be recycled.
