Description

Technical Field

[0001] This invention relates to the field of airbag manufacturing, and in particular to an automatic feeding mechanism for deep-drawn thin materials for automotive airbag gas generators. Background Technology

[0002] As a core component of passive safety systems, the manufacturing of the metal shell of automotive airbag gas generators typically involves deep drawing of thin sheet metal materials such as stainless steel or low carbon steel. The deep drawing process places high demands on the positioning accuracy of the sheet metal and the feeding cycle.

[0003] In existing technologies, during the deep drawing of automotive airbag inflator housings, operators typically manually separate and pick up sheets from the stack and place them into the drawing die. This feeding method is not only inefficient and has an unstable feeding cycle, but also suffers from oil film adsorption or vacuum effects between the thin sheets, making it difficult for operators to ensure stable and individual separation of each sheet. This can lead to the simultaneous feeding of two or more sheets due to negligence, causing die damage or product scrap. Therefore, there is an urgent need to research an automatic feeding mechanism for deep-drawing thin sheets for automotive airbag inflators to solve these problems. Summary of the Invention

[0009] As a preferred embodiment of the present invention, the displacement assembly includes a slide rail horizontally fixed to the upper surface of a support plate and a rack horizontally fixed to one side of the slide rail; the slide rail and the rack are arranged parallel to each other; a guide block is slidably connected to the slide rail; a second motor is vertically fixed to the upper surface of the guide block; the output shaft of the second motor passes through the guide block and is fixedly fitted with a gear that meshes with the rack.

[0010] As a preferred embodiment of the present invention, the push-pull assembly includes a pair of second pillars that are vertically fixed side by side to the upper surface of the guide block; the upper ends of the two second pillars are connected by a horizontally arranged second mounting plate; a second cylinder is vertically fixed to the upper surface of the second mounting plate; the output end of the second cylinder slides through the second mounting plate and is fixed with a push-pull strip parallel to the slide rail, and both second pillars slide through the push-pull strip.

Detailed Implementation

[0025] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0026] Example 1: like Figures 1-4 As shown in the figure, an automatic feeding mechanism for deep-drawn thin materials for automotive airbag gas generators provided by an embodiment of the present invention includes a horizontally arranged support plate 1 and a loading platform 2 horizontally arranged above the support plate 1; the upper surface of the loading platform 2 can stack multiple sheets; the support plate 1 is equipped with a lifting component 3 connected to the loading platform 2 and a positioning component 4 corresponding to the loading platform 2; the lifting component 3 can drive the loading platform 2 to move up and down; the positioning component 4 can position the sheets on the loading platform 2; a displacement component 5 is horizontally installed on one side of the loading platform 2; a push-pull component 6 is vertically connected to the displacement component 5; a gripping component 7 corresponding to the loading platform 2 is connected to the push-pull component 6; a separating component 8 is installed on the side of the gripping component 7; the separating component 8 can separate the multiple sheets gripped by the gripping component 7. The displacement component 5 drives the gripping component 7 to move directly above the loading platform 2. Then, the lifting component 3 drives the loading platform 2 upward, causing the top sheet on the loading platform 2 to be gripped by the gripping component 7. The push-pull component 6 then drives the gripping component 7 to move up and down. At the same time, the separating component 8 separates the multiple sheets gripped by the gripping component 7, and the separated sheets fall back onto the sheets on the loading platform 2. Then, the displacement component 5 drives the gripping component 7 to move linearly, causing the gripping component 7 to move to the loading station. Finally, the gripping component 7 lowers the gripped sheets. This not only improves the loading efficiency but also avoids problems such as simultaneous loading of two or more sheets. It also ensures the stability of the feeding cycle and avoids problems such as mold damage or product scrap.

[0027] Among them, such as Figures 5-6 As shown, in order to improve the accuracy of sheet material supply, the lifting assembly 3 is designed to include multiple guide rods 301 with their upper ends bolted to the lower surface of the loading platform 2, and a first motor 302 with its vertical bolts connected to the lower surface of the support plate 1; the multiple guide rods 301 are vertically slidably inserted into the support plate 1; the output shaft of the first motor 302 passes through the support plate 1 and is coaxially fixed with a screw 303; a screw sleeve 304 is threaded onto the screw 303; a lifting plate 305 is horizontally bolted onto the screw sleeve 304; one end of the lifting plate 305 is bolted to the lower surface of the loading platform 2. When the gripping assembly 7 moves to directly above the loading platform 2, it stacks multiple sheets on the loading platform 2. The first motor 302 drives the screw 303 to rotate, causing the screw sleeve 304 to move the loading platform 2 upward to a height consistent with the thickness of a single sheet via the lifting strip 305. This causes the sheet at the top to be gripped by the gripping assembly 7, thereby achieving sheet supply and effectively ensuring sheet supply efficiency.

[0028] Example 2: Based on Example 1, as follows Figures 5-7As shown, in order to improve the positioning effect of the sheet and avoid misalignment with other sheets after the separated sheet falls back onto the loading platform 2, thus affecting the feeding accuracy of the sheet, four through slots 101 are designed on the upper surface of the support plate 1; the four through slots 101 are respectively set around the loading platform 2; the upper surface of the lifting strip 305 is provided with a clearance groove 306 along the length direction; the positioning component 4 includes four sliders 401 that are slidably connected in the four through slots 101, and any slider 401 moves closer to or away from the loading platform 2 by sliding in the through slot 101; positioning strips 402 are vertically welded to the upper surface of each of the four sliders 401; one positioning strip 402 slides through the clearance groove 306. Within 06, the positioning strip 402 can approach or move away from the loading platform 2 within the clearance groove 306; a first mounting plate 403 is horizontally arranged between the four sliders 401; the first mounting plate 403 is located below the support plate 1; the first mounting plate 403 and the support plate 1 are connected by multiple vertically arranged first pillars 404; a first cylinder 405 is vertically bolted to the lower surface of the first mounting plate 403; the output end of the first cylinder 405 slides through the first mounting plate 403 and is bolted to a movable block 406; four first transmission rods 407 are rotatably connected to the side of the movable block 406; the ends of the four first transmission rods 407 away from the movable block 406 are rotatably connected to the four sliders 401 respectively. When the topmost sheet is gripped by the gripping assembly 7, its horizontal position is higher than the uppermost horizontal position of the positioning strip 402. Then, the lifting assembly 3 moves the loading platform 2 downwards by a distance N times the thickness of a single sheet (N is a positive integer). At this point, the horizontal position of the topmost sheet on the loading platform 2 is lower than the uppermost horizontal position of the positioning strip 402. Then, the push-pull assembly 6 moves the gripping assembly 7 up and down, while the separating assembly 8 separates the multiple sheets gripped by the gripping assembly 7. The separated sheets fall back onto the loading platform 2, and at this point, the horizontal position of the topmost sheet on the loading platform 2 is still lower than the uppermost horizontal position of the positioning strip 402. Then, the first cylinder 405 drives the movable block 406. The downward movement causes the movable block 406 to pull the four sliders 401 through the first transmission rod 407 to slide in the four through slots 101 respectively, so that the four positioning strips 402 are simultaneously brought close to the loading platform 2, and finally the four positioning strips 402 abut against the four sides of the sheet, thereby correcting the position of the sheet on the loading platform 2 and ensuring that the sheet on the loading platform 2 is always in a neat state, thus ensuring the feeding accuracy of the sheet; in addition, when the gripping component 7 moves to the top of the loading platform 2 again (i.e., gripping again), the lifting component 3 drives the loading platform 2 to move downward by a distance N+1 times the thickness of a single sheet, so that the sheet at the top is gripped by the gripping component 7, effectively ensuring the feeding effect of the sheet.

[0029] Example 3: Based on Example 2, as follows Figure 8 As shown, to improve the sheet feeding efficiency, the displacement component 5 is designed to include a slide rail 501 horizontally bolted to the upper surface of the support plate 1 and a rack 502 horizontally bolted to one side of the slide rail 501. The slide rail 501 and the rack 502 are arranged parallel to each other. A guide block 503 is slidably connected to the slide rail 501. A second motor 504 is vertically bolted to the upper surface of the guide block 503. The output shaft of the second motor 504 passes through the guide block 503 and is keyed to a gear 505 that meshes with the rack 502. By driving the gear 505 through the second motor 504, the gear 505 moves on the rack 502, thereby quickly transferring the gripped sheet to the feeding position, effectively ensuring the sheet feeding efficiency.

[0030] Among them, such as Figure 8 As shown, to ensure the consistency of the vibration amplitude of the sheet during sheet separation, the push-pull assembly 6 is designed to include a pair of parallel vertical bolts connecting the second pillars 601 to the upper surface of the guide block 503; the upper ends of the two second pillars 601 are connected by a horizontally arranged second mounting plate 602, and the second mounting plate 602 is bolted to the second pillars 601; a second cylinder 603 is vertically bolted to the upper surface of the second mounting plate 602; the output end of the second cylinder 603 slides through the second mounting plate 602 and is bolted to a push-pull strip 604 parallel to the slide rail 501, and both second pillars 601 slide through the push-pull strip 604. When the gripping assembly 7 grips the sheet, the second cylinder 603 drives the push-pull strip 604 to move up and down reciprocally, causing the gripping assembly 7 to drive the gripped sheet to move up and down rapidly, thereby increasing the vibration amplitude of the sheet and giving the sheet a downward throwing force, thus accelerating the separation efficiency and effect between multiple sheets.

[0031] Among them, such as Figure 8 As shown, to facilitate the gripping of the sheet material, the gripping assembly 7 includes a pair of bearing strips 701 horizontally bolted to both ends of the push-pull strip 604; both bearing strips 701 are perpendicular to the push-pull strip 604; multiple conventional negative pressure suction nozzles 702 are vertically bolted side-by-side along the length of each push-pull strip 604; the suction end of any negative pressure suction nozzle 702 is vertically downward. In use, the multiple negative pressure suction nozzles 702 on the two push-pull strips 604 respectively grip the opposite sides of the sheet material, ensuring the stability of the sheet material gripping.

[0032] Example 4: Based on Example 3, as follows Figures 9-10As shown, in order to improve the separation efficiency of the sheet material, the material separating component 8 is designed to include a pair of first strips 801 arranged side by side and a pair of second strips 802 arranged side by side on one side of the two first strips 801; the two first strips 801 and the two second strips 802 are respectively arranged on opposite sides of the loading platform 2, and the two push-pull strips 604 can move between the two first strips 801 or between the two second strips 802; the lower ends of the two first strips 801 and the lower ends of the two second strips 802 are connected to U-shaped blocks 803; the two pairs of U-shaped blocks 803 are bolted to the upper surface of the support plate 1; the upper end of any one of the first strips 801 is connected to the upper end of the corresponding second strip 802 by a pair of conventional brush rollers 804 (the brush rollers 804 consist of a roller body and multiple radially fixed to the circumferential sidewalls of the roller body). The two brush rollers 804 are connected to the first strip 801 and the second strip 802 respectively. Both push-pull strips 604 can move between the two pairs of brush rollers 804. The two pairs of brush rollers 804 are rotatably connected to the first strip 801 and the two second strips 802 respectively. One end of each pair of brush rollers 804 is keyed to a first pulley 805, and the two first pulleys 805 on any pair of brush rollers 804 are connected by a synchronous belt drive. The other end of any brush roller 804 on the two first strips 801 is keyed to a second pulley 806. The two second pulleys 806 are respectively connected to a third pulley 807 by a synchronous belt drive. The two third pulleys 807 are respectively keyed to the output shaft of a pair of third motors 808. The two third motors 808 are respectively bolted to the two second strips 802. When the gripping assembly 7 moves the gripped sheet rapidly up and down, both first strips 801 and both second strips 802 are in a vertical position, meaning the two brush rollers 804 on any one of the first strips 801 are in an up-and-down configuration. The third motor 808 drives the brush rollers 804 to rotate via the third pulley 807, the second pulley 806, and the first pulley 805. (Refer to...) Figure 2 As shown, the brush roller 804 on the left rotates clockwise, while the brush roller 804 on the right vibrates counterclockwise. The bristles of the brush roller 804 act on the edge of the sheet, thereby giving the sheet a downward pulling force. Thus, with the cooperation of the push-pull assembly 6 and the material distribution assembly 8, multiple sheets are separated, avoiding problems such as simultaneous feeding of two or more sheets.

[0033] Example 5: Based on Example 4, as follows Figures 9-10As shown, since the second cylinder 603 only has two actions, extension and retraction, and the shorter the stroke of the output end of the second cylinder 603, the greater the vibration amplitude of the sheet, and the greater the downward force exerted on the sheet by the push-pull assembly 6, the faster the sheet separation effect can be achieved. However, since both first strips 801 and both second strips 802 are in a vertical state, the two brush rollers 804 on any one of the first strips 801 are in an up-down setting. This will cause interference between the gripping assembly 7 and the brush rollers 804 when the gripping assembly 7 moves between the two pairs of brush rollers 804, if the stroke value of the output end of the second cylinder 603 is less than the distance value between the two brush rollers 804 on any one of the first strips 801. This causes the material gripping component 7 to be unable to move between the two pairs of brush rollers 804. Furthermore, when the lifting component 3 drives the material platform 2 to feed material, the horizontal position of the uppermost sheet is higher than the horizontal position of the upper end of the positioning strip 402. At this time, the brush rollers 804 will collide with the uppermost sheet, causing displacement of the uppermost sheet and affecting feeding accuracy. Therefore, to avoid interference between the material gripping component 7 and the brush rollers 804 and to ensure feeding accuracy, an adjusting component 9 is designed to connect to the material distribution component 8. The lower ends of the two first strips 801 and the lower ends of the two second strips 802 are rotatably connected to two pairs of U-shaped blocks 803 respectively. The adjusting component 9 includes a pair of parallel horizontal... A double-acting lead screw 901 is located below the support plate 1; both double-acting lead screws 901 are parallel to the rack 502; a pair of mounting blocks 902 are rotatably connected to each double-acting lead screw 901; both pairs of mounting blocks 902 are bolted to the lower surface of the support plate 1; a nut 903 is threaded onto each threaded section of each double-acting lead screw 901; a second transmission rod 904 is rotatably connected to each pair of nuts 903; the ends of the two pairs of second transmission rods 904 away from the nuts 903 are respectively rotatably connected to the two first strips 801 and the two second strips 802; a fourth motor 905 is horizontally arranged between the two double-acting lead screws 901; the fourth motor 905 is bolted to one side of the support plate 1; the fourth... The output shaft of motor 905 is keyed to a fourth pulley 906; a fifth pulley 907 is provided on each of the opposite sides of the fourth pulley 906; the two fifth pulleys 907 are keyed to two double-acting lead screws 901 respectively; the fourth pulley 906 and the two fifth pulleys 907 are connected by a synchronous belt; a pair of tensioning pulleys distributed vertically are provided on each of the opposite sides of the fourth pulley 906, and any pair of tensioning pulleys are connected by a bracket with a "Π" shaped structure; both brackets are bolted to the lower surface of the support plate 1; the two pairs of tensioning pulleys are used to tension the synchronous belt between the fourth pulley 906 and the two fifth pulleys 907 to ensure the transmission effect between the fourth pulley 906 and the two fifth pulleys 907.When the material gripping assembly 7 needs to move between or out of the two pairs of brush rollers 804, the fourth motor 905 drives the bidirectional lead screw 901 to rotate via the fourth pulley 906 and the fifth pulley 907. This causes the two lead screw nuts 903 on the bidirectional lead screw 901 to move apart. Then, the second transmission rod 904 pushes the first strip 801 and the second strip 802 from a vertical state to an inclined state, so that the horizontal position of the gripped sheet is higher than the horizontal position of the brush rollers 804. This avoids interference between the sheet and the brush rollers 804, as well as interference between the material gripping assembly 7 and the brush rollers 804. This ensures both the separation effect of the sheet and the transfer stability of the sheet.

[0034] The above-disclosed embodiments are merely a few specific examples of the present invention.
