Description

Technical Field

[0001] This utility model specifically relates to a dot printing machine for processing automotive airbags, belonging to the field of automotive airbag processing technology. Background Technology

[0002] As a core passive safety protection device in automobiles, car airbags must be used in conjunction with seat belts. In the event of a collision, they inflate and deploy rapidly, forming an elastic buffer barrier between the occupants and the vehicle body. This effectively reduces the impact force on critical areas such as the head and chest of the occupants, significantly lowering the risk of injury. They are an indispensable and important component of modern automotive safety systems.

[0003] In the production and processing of automotive airbags, precise markings are required for semi-finished airbags of different models and specifications, based on design requirements. These markings are not only important reference standards for subsequent assembly and testing processes, but also a key prerequisite for ensuring the installation accuracy and safety of airbags.

[0004] In the existing technology, there are two main ways to implement related dot printing operations: one is to rely on manual hand-held molds to complete the dot printing. This method is cumbersome to operate, and workers are prone to fatigue after working for a long time. Not only is the dot printing efficiency low, but it is also very easy for human operation errors to cause the mark position deviation, affecting the subsequent process. The other is to use a dot printing machine as disclosed in Chinese utility model patent with publication number CN220660845U. It replaces manual operation to a certain extent through the cooperation of moving components, telescopic cylinders and dot printing processing components, but still has obvious defects.

[0005] Specifically, due to significant differences in the number and distribution of markings required for airbags of different batches and specifications, operators must manually rotate the fixing bolts on the top of the movable frame each time the processing batch is changed or the marking scheme is adjusted. This process is cumbersome and redundant, consuming a large amount of time and reducing production efficiency. Furthermore, operator fatigue from repetitive operations can lead to uneven bolt tightening and misalignment of markings, making it difficult to guarantee the consistency and accuracy of the markings and affecting the production quality and assembly precision of the airbags. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a dot-printing machine for automotive airbag processing, which can significantly shorten adjustment time and ensure the consistency and accuracy of dot-printing marks.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a dot printing machine for processing automotive airbags, comprising:

[0008] The table body has a mounting bracket fixedly connected to its front side.

[0009] Dot pen body;

[0010] An adjustment component, fixedly mounted on the lower surface of the mounting bracket, is used to adjust the position of the dot-print pen body;

[0011] The fixing component is slidably set inside the adjusting component and is used to fix the position of the dot pen body.

[0012] Preferably, the adjustment component includes:

[0013] A cylinder is fixedly mounted on the lower surface of a mounting frame. The output end of the cylinder passes through the mounting frame and is fixedly connected to a lifting frame. Several first crossbars are fixedly connected to the inner surface of the mounting frame. A mounting seat is slidably connected between the outer surfaces of two first crossbars. A first mounting groove is formed through the upper surface of the mounting seat. The dot pen body is slidably mounted inside the first mounting groove. A limit ring is fixedly connected to the inner surface of the first mounting groove.

[0014] The second crossbar has several fixedly installed on the inner surface of the lifting frame. A fixing block is slidably connected between the outer surfaces of two second crossbars. A fixing rod is fixedly connected to the lower surface of the fixing block. The fixing rod is slidably installed inside the first mounting groove. The cylinder can drive the lifting frame to achieve vertical position adjustment, thereby driving the fixing block and fixing rod to move synchronously. The mounting seat can slide horizontally along the first crossbar, and the fixing block can slide horizontally along the second crossbar. With the first mounting groove and the limiting ring limiting the position of the dot pen body, the position adjustment of the dot pen body in multiple dimensions is realized, which greatly improves the flexibility of dot position adjustment. Moreover, the adjustment process does not require disassembling the fixing parts one by one, saving adjustment time.

[0015] Preferably, a first control plate is fixedly connected to the upper surface of the mounting base. The first control plate is slidably connected to the fixing block. The first control plate enables the mounting base and the fixing block to slide synchronously on the outer surfaces of the first and second crossbars, ensuring the consistency of movement of the mounting base and the fixing block.

[0016] Preferably, the upper surface of the second crossbar is provided with a scale, which can intuitively display the position of the fixing block. The operator can accurately control the position of the fixing block and the mounting base according to the scale, and then accurately adjust the position of the dot pen body, reducing the error of manual adjustment and improving the consistency of the dot marking of different batches of airbags.

[0017] Preferably, two limiting rods are fixedly connected to the upper surface of the mounting frame, and two limiting grooves are opened on the upper surface of the lifting frame. The limiting rods are slidably arranged inside the limiting grooves. The limiting rods and the limiting rods slide together to guide and limit the vertical lifting of the lifting frame, preventing the lifting frame from rotating or deviating under the drive of the cylinder, and ensuring the stability of the lifting process.

[0018] Preferably, the fixing component includes:

[0019] The first toothed plate has a second mounting groove inside the fixing block. The first toothed plate is slidably disposed at the center position inside the second mounting groove. A spring is fixedly connected between the first toothed plate and the second mounting groove. Two second toothed plates are slidably connected to the inner surface of the second mounting groove. Two rotating shafts are rotatably connected to the inner surface of the second mounting groove. Gears are fixedly connected to the outer surface of the rotating shafts. Both the first toothed plate and the second toothed plate are meshed with the gears. Anti-slip pads are fixedly connected to the outer surfaces of both the first toothed plate and the second toothed plate.

[0020] The second control plate is fixedly mounted on the upper surface of the first toothed plate. The upper surface of the fixed block has a movable groove, and the second control plate is slidably mounted inside the movable groove. The operator can slide the second control plate to drive the first toothed plate to move. Under the meshing transmission of the gears, the two second toothed plates move in opposite directions. With the elastic reset effect of the spring, the clamping and loosening of the fixed block can be quickly realized, thereby realizing the rapid tightening and loosening of the mounting base and the dot pen body. This replaces the traditional bolt locking method, which is convenient to operate and has uniform locking force, greatly shortening the fixing and unlocking time.

[0021] Preferably, the front side of the table has two lifting slots, and a lifting plate is slidably connected between the inner surfaces of the two lifting slots. A first motor is fixedly connected to the upper surface of the table. The output end of the first motor extends into the interior of the lifting slot and is fixedly connected to a threaded rod. The threaded rod is threadedly connected to the lifting plate. The first motor drives the threaded rod to rotate, and through the threaded transmission, drives the lifting plate to move vertically along the lifting slot, so that the airbag contacts the dot pen body to perform the dot printing operation.

[0022] Preferably, the upper surface of the lifting plate has two sliding grooves, and the inner surfaces of the two sliding grooves are slidably connected to sliders. The upper surface of the sliders is fixedly connected to an arc-shaped clamping plate. The right side of the lifting plate is fixedly connected to a second motor. The output end of the second motor extends into the interior of the sliding groove and is fixedly connected to a bidirectional threaded rod. Both sliders are threadedly connected to the bidirectional threaded rod. The second motor drives the bidirectional threaded rod to rotate, and through threaded transmission, it drives the two sliders to move closer or further away from each other along the sliding groove, thereby driving the arc-shaped clamping plate to automatically clamp and release the airbag. This replaces the manual fixing method, has high fixing efficiency and uniform clamping force, avoids the displacement of the airbag caused by manual fixing, and ensures the stability and accuracy of the dotting process.

[0023] The beneficial effects of this utility model are as follows: This dot printing machine for processing automotive airbags, through the cooperation of the adjusting component and the fixing component, allows the operator to adjust the position of the dot printing pen body simply by moving the second control plate and then sliding the first control plate. Subsequently, by releasing the second control plate, the position of the fixing block is fixed by the anti-slip pads fixed on the surfaces of the first and second toothed plates, thereby fixing the position of the mounting base and the dot printing pen body, greatly shortening the adjustment time and ensuring the consistency and accuracy of the dot printing marks.

The fixing rod 29 is slidably installed inside the first mounting groove 24. The cylinder 2 can drive the lifting frame 21 to achieve vertical position adjustment, thereby driving the fixing block 28 and the fixing rod 29 to move synchronously. The mounting base 23 can slide horizontally along the first crossbar 22, and the fixing block 28 can slide horizontally along the second crossbar 27. With the first mounting groove 24 and the limiting ring 26 limiting the position of the dot pen body 25, the position adjustment of the dot pen body 25 in multiple dimensions is realized, which greatly improves the flexibility of dot position adjustment. Moreover, the adjustment process does not require disassembling the fixing parts one by one, saving adjustment time.

[0040] Preferably, a first control plate 210 is fixedly connected to the upper surface of the mounting base 23. The first control plate 210 is slidably connected to the fixing block 28. The first control plate 210 can make the mounting base 23 and the fixing block 28 slide synchronously on the outer surfaces of the first crossbar 22 and the second crossbar 27, ensuring the consistency of movement of the mounting base 23 and the fixing block 28.

[0043] Preferably, the fixing component includes:

[0044] The first toothed plate 51 and the fixing block 28 have a second mounting groove 5 inside. The first toothed plate 51 is slidably positioned at the center of the second mounting groove 5.

The first toothed plate 51 and the second toothed plate 53 are both meshed with the gears 55. Anti-slip pads 56 are fixedly connected to the outer surfaces of the first toothed plate 51 and the second toothed plate 53.

[0045] The second control plate 58 is fixedly mounted on the upper surface of the first toothed plate 51. The upper surface of the fixed block 28 has a movable groove 57, and the second control plate 58 is slidably mounted inside the movable groove 57. The operator can move the first toothed plate 51 by sliding the second control plate 58. Under the meshing transmission of the gear 55, the two second toothed plates 53 are moved in opposite directions. With the elastic reset effect of the spring 52, the clamping and loosening of the fixed block 28 can be quickly realized, thereby realizing the rapid tightening and loosening of the mounting base 23 and the dot pen body 25. This replaces the traditional bolt locking method, which is convenient to operate and has uniform locking force, greatly shortening the fixing and unlocking time.

[0046] Preferably, the front side of the table body 1 has two lifting grooves 6, and a lifting plate 61 is slidably connected between the inner surfaces of the two lifting grooves 6. A first motor 62 is fixedly connected to the upper surface of the table body 1. The output end of the first motor 62 extends into the interior of the lifting groove 6 and is fixedly connected to a threaded rod 63. The threaded rod 63 is threadedly connected to the lifting plate 61. The first motor 62 drives the threaded rod 63 to rotate, and through the threaded transmission, drives the lifting plate 61 to move vertically along the lifting groove 6, so that the airbag contacts the dotting pen body 25 to perform the dotting operation.

[0047] Preferably, the upper surface of the lifting plate 61 has two sliding grooves 7, and the inner surfaces of the two sliding grooves 7 are slidably connected to sliders 71. The upper surface of the sliders 71 is fixedly connected to an arc-shaped clamping plate 72. The right side of the lifting plate 61 is fixedly connected to a second motor 73. The output end of the second motor 73 extends into the interior of the sliding groove 7 and is fixedly connected to a bidirectional threaded rod 74. Both sliders 71 are threadedly connected to the bidirectional threaded rod 74. The second motor 73 drives the bidirectional threaded rod 74 to rotate, and through the threaded transmission, it drives the two sliders 71 to move closer or further away from the sliding grooves 7 synchronously, thereby driving the arc-shaped clamping plate 72 to automatically clamp and release the airbag, replacing the manual fixing method. This method has high fixing efficiency and uniform clamping force, avoids the displacement of the airbag caused by manual fixing, and ensures the stability and accuracy of the dotting process.

[0048] The operating principle of the dotting machine for processing automotive airbags in this embodiment is as follows: When the position of the dotting pen body 25 needs to be adjusted, the second control plate 58 is pulled forward to drive the first toothed plate 51 to move synchronously and compress the spring 52. Under the meshing transmission of the gear 55, the two second toothed plates 53 are driven to move in opposite directions, so that the anti-slip pads 56 fixed on the surfaces of the first toothed plate 51 and the second toothed plate 53 are separated from the second crossbar 27, releasing the fixation of the fixing block 28. Then, the first control plate 210 is pulled to drive the mounting base 23, the fixing block 28 and the dotting pen. The main body 25 moves on the surfaces of the first crossbar 22 and the second crossbar 27. The position of the dot pen body 25 can be read by observing the scale 3. After moving to the desired position, the second control plate 58 is released. Under the elastic force of the spring 52, the anti-slip pads 56 fixed on the surfaces of the first toothed plate 51 and the second toothed plate 53 are once again attached to the second crossbar 27, thereby fixing the fixing block 28, the mounting base 23 and the dot pen body 25. Then, the airbag is placed at the center of the upper surface of the lifting plate 61, and the second motor 73 operates. The first motor 62 drives the bidirectional threaded rod 74 to rotate, causing the two sliders 71 to drive the arc-shaped clamping plate 72 to clamp and fix the airbag. Then, the first motor 62 drives the threaded rod 63 to rotate, driving the lifting plate 61 to move upward along the lifting groove 6, so that the airbag is released from the dotting pen body 25 for dotting operation. When the dotting pen body 25 needs to be replaced, the cylinder 2 drives the lifting frame 21 to move upward along the limit rod 4, thereby driving the second crossbar 27 and the fixing block 28 to move upward on the surface of the first control plate 210, so that the fixing rod 29... Slide out from inside the first mounting slot 24, then pull the second control plate 58 and move the first control plate 210 to move the fixing block 28 and mounting base 23 to the far right, remove the dot pen body 25 from inside the first mounting slot 24, and then slide the new dot pen body 25 into the first mounting slot 24 so that the dot pen body 25 fits against the limiting ring 26. Then the cylinder 2 works again to drive the lifting frame 21 to move downward, so that the fixing rod 29 slides into the first mounting slot 24 again to fix the dot pen body 25.
