Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment, and more specifically, to a tooling for wrapping airbag tape. Background Technology

[0002] Automotive airbags are a crucial component of a vehicle's passive safety system, and their reliability and assembly quality directly impact occupant safety. Folding and securing the airbag is a key step in the manufacturing process. Currently, the industry standard for securing folded airbags is by manually applying tape. The specific procedure involves workers manually cutting a predetermined length of tape and then manually wrapping it around the surface of the folded airbag to maintain its shape during transportation and storage.

[0003] However, this manual labor-intensive work model has many inherent drawbacks, which severely restrict the improvement of product quality and production efficiency, mainly in the following aspects:

[0004] Poor assembly quality consistency and low product reliability. Because the system relies entirely on operator experience and subjective judgment, deviations occur in the tape cutting length and inaccurate application, leading to missed, incorrect, or improperly applied tape. These minute deviations can directly result in the airbag not being securely fixed in its folded state. In the event of a vehicle collision and the moment the airbag needs to deploy, an improperly fixed airbag may fail to deploy as intended, or even tear, causing airbag malfunction and posing a significant safety hazard.

[0005] Low production efficiency and high costs. The tedious and slow process of manually applying tape has become a bottleneck on the production line, making it difficult to adapt to the pace of modern large-scale, high-efficiency production. In addition, any misapplied or missing tape means that the product may be scrapped or require time-consuming rework. This not only increases the direct scrap cost in the production process, but also generates additional inspection and repair costs, thus driving up the overall manufacturing cost of the product and making it difficult to meet the increasingly stringent cost control requirements of the market.

[0006] This job violates ergonomic principles and poses occupational health risks. It requires employees to perform high-intensity, highly repetitive, and delicate operations. Prolonged work can easily lead to hand fatigue and even cumulative musculoskeletal damage, which not only affects employee health but also further exacerbates the risk of inconsistent quality due to employee fatigue.

[0007] The process lacks controllability, making standardization and traceability difficult. The high degree of randomness in manual operation makes it impossible to quantify and control key process parameters such as tape adhesion tension and bonding strength, hindering standardized operations. Furthermore, the lack of process data records makes effective cause tracing and responsibility determination difficult in the event of product quality problems.

[0008] Therefore, the existing manual tape-applying assembly method cannot meet the modern automotive industry's demands for high reliability, consistency, and efficiency in the production of safety components in terms of quality, efficiency, cost, and ergonomics. An automated and intelligent solution that can overcome these shortcomings is urgently needed.

[0009] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this utility model, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0033] The tooling for wrapping airbag tape according to the present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments are not intended to limit the scope of protection of the present invention.

[0034] This utility model provides a tooling for wrapping airbag tape. Figure 1 This is a schematic diagram of the structure of a tooling for wrapping airbag tape according to an embodiment of the present invention. Specifically, the tooling for wrapping airbag tape includes a support unit, an airbag clamping unit 2, and a tape unit 3;

[0035] A support unit may include a support plane and support columns standing on the support plane. The support columns here are not limited to a single column, but can refer to multiple support columns that are perpendicular to the support plane. Figure 1 In one embodiment, the support unit includes a horizontal support plane 11 and a support column 12 on one side of the support plane 11.

[0036] The airbag clamping unit 2 is fixed to the support plane 11. Figures 2 to 4 The following are schematic diagrams, side views, and top views of a tooling airbag clamping unit for wrapping airbag tape according to an embodiment of the present invention. In this embodiment, the airbag clamping unit 2 is fixedly connected to the support plane 11 via a support base 29. Meanwhile, in order to facilitate the assembly and disassembly of the airbag clamping unit 2, the support base 29 may be provided with an installation handle 291.

[0037] The airbag clamping unit 2 includes an operating platform, a first baffle 22, a second baffle 23, and a movable component 24. The operating platform can be a plane or a surface like a plane. Figure 1 The system includes a stepped first support surface 21 and a second support surface 211, the height difference of which can be set according to the size of the airbag of the tape to be wrapped. A first baffle 22 is fixedly installed on the first support surface 21 of the operating platform, and a movable component 24 is slidably connected to the second support surface 211 of the operating platform. A second baffle 23 is installed on the side of the movable component 24 facing the first baffle 22. By sliding the movable component 24, the second baffle 23 is moved closer to or away from the first baffle 22 to achieve the function of clamping or releasing the airbag of the tape to be wrapped.

[0038] More specifically, the sliding connection between the movable component 24 and the second support surface 211 of the operating platform can be achieved in the following way: a slide rail 212 is provided on the second support surface 211 of the operating platform, and the movable component 24 is slidably connected to the slide rail 212 via a slider (not shown in the figure). Of course, the sliding connection between the movable component and the operating platform is not limited to the above method.

[0039] To initially position the airbag of the tape to be wrapped, the first baffle 22 may be provided with a groove 221, which is adapted to the bolt of the airbag 9 of the tape to be wrapped, thereby locking the airbag of the tape to be wrapped. At the same time, in order to facilitate the sliding of the moving part, and thus conveniently clamp or release the airbag of the tape to be wrapped, in this embodiment, a push-pull handle 241 may be provided on the moving part 24.

[0040] The airbag clamping unit also includes a positioning groove 213 and a positioning element 242 adapted to the positioning groove 213. The positioning groove 213 is disposed on the operating platform, and the positioning element 242 is disposed on the movable element 24. When the movable element 24 moves to a preset position, the positioning element 242 engages with the positioning groove 213 to achieve positioning. The preset position is set according to the position of the second baffle when the airbag to be wrapped with tape is fixedly clamped. In order to make the tooling of this utility model applicable to tape wrapping of different types of airbags, the positioning groove 213 can be fixed at different positions of the movable element 24.

[0041] In some embodiments, the airbag clamping unit further includes a limiting member 25, which is disposed on one end of the operating platform away from the first baffle 22, and is used to limit the maximum travel of the moving member 24 away from the first baffle 22.

[0042] The limiting member 25 may be a physical limiting block. In some other embodiments, the airbag clamping unit also includes a sensor for detecting the position of the end of the moving member 24 away from the first baffle 22 and emitting a signal when it moves to a set position.

[0043] The tape unit of the tooling for wrapping airbag tape is provided on the support column 12 and may include a tape roll receiving part 31 and a cutting part 32. The tape roll receiving part 31 is used to install the tape roll and is provided in a position that is convenient for the operator to access. The cutting part 32 is provided on the tape output path of the tape roll receiving part 31 and is used to cut the tape drawn from the tape roll.

[0044] In some embodiments, the airbag clamping unit may further include a laser line marker 4 for generating horizontal and / or vertical laser lines to guide the wrapping of the adhesive tape. The laser line marker 4 can project multiple independent laser points for positioning or centering. For example, a three-line laser can project one horizontal line and two vertical lines (forming two crosses), or a five-line laser can project one horizontal line, two vertical lines, and simultaneously project one laser point upwards and downwards (forming a plumb line). The operator can wrap the adhesive tape 8 around the airbag 9 according to these laser guide lines generated by the laser line marker 4.

[0045] Furthermore, the airbag clamping unit may also include an image unit 5, which includes:

[0046] Image acquisition device, used to acquire images of airbags that have been wrapped with tape;

[0047] The processing module stores an image analysis algorithm to analyze images and output a judgment result on whether the tape wrapping is qualified. This utility model's fixture for airbag tape wrapping can accurately determine whether the tape position is correct and whether it is missed or misapplied through the image unit 5. This avoids a series of problems such as low efficiency, high product failure rate, and high assembly safety risks associated with manual assembly, improving operational convenience and the actual assembly effect.

[0048] The structure of the tooling for wrapping airbag tape according to this invention is further explained below by describing the operation method. The tooling for wrapping airbag tape includes the following steps:

[0049] The folded airbag 9 is placed at the first baffle 22, and the bolt of the airbag 9 is locked in the groove 221 of the first baffle 22 for positioning.

[0050] Pulling the push-pull handle 241 causes the moving part 24 to move along the slide rail 212 toward the first baffle 22 until the positioning part 242 of the moving part 24 is engaged in the positioning groove 213. At this time, the first baffle 22 and the second baffle 23 of the airbag completely fix the folded airbag 9.

[0051] The operator takes the tape of the set length from the cutting section 32 of the tape unit and wraps the tape around the folded airbag 9 using the guide line emitted by the laser marking instrument 4;

[0052] The image unit is activated to inspect the airbag 9 wrapped with tape. If the inspection is qualified, the operator pulls the push-pull handle 241 to move the moving part 24 away from the first baffle 22, thereby loosening the airbag 9 wrapped with tape. The operator then removes the airbag to complete the assembly.

[0053] It should be noted that in the technical solution of the tooling for wrapping airbag tape of this utility model, each of the functional modules and module units included can correspond to the specific hardware circuit in the integrated circuit structure. Therefore, it only involves the improvement of the specific hardware circuit. The hardware part is not merely a carrier for executing control software or computer programs. Therefore, solving the corresponding technical problem and obtaining the corresponding technical effect does not involve the application of any control software or computer programs. In other words, this utility model can solve the technical problem and obtain the corresponding technical effect by simply using the improvements in the hardware circuit structure involved in these modules and units, without the need for specific control software or computer programs to achieve the corresponding function.
