Description

Technical Field

[0001] This utility model belongs to the field of automotive interior component buckle testing technology, and in particular relates to an automotive interior component buckle strength testing device. Background Technology

[0002] The production of automotive interior parts is a key link in automobile manufacturing. It refers to the process of processing materials such as plastics, leather, fabrics, and carbon fibers into functional or decorative components such as dashboards, door panels, and seat covers through processes such as injection molding, hot pressing, and surface treatment. In the production and assembly process of automotive interior parts, clips are widely used to connect different components, and their assembly quality directly affects the firmness of the interior parts and the overall quality of the vehicle.

[0003] Currently, the installation of clips mainly relies on manual operation. Judging whether the clips are accurately and completely assembled, as well as whether there are any missing clips, also depends entirely on the visual observation and experience of the operators. This manual judgment method has significant subjectivity and instability. Operators may fail to detect incomplete or missing clips in time due to fatigue, distraction, poor lighting conditions, or the clips being hidden and difficult to observe. Once a poorly assembled clip flows into the subsequent stages, it will lead to the risk of loose connections, abnormal noises, or even detachment of interior parts, seriously affecting product reliability and user satisfaction, and is detrimental to use.

[0004] To address this issue, we provide a device for testing the snap-fit ​​strength of automotive interior parts, thereby resolving the aforementioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a device for testing the strength of automotive interior parts clips. By combining the clip connection strength testing component and the clip installation testing component, it solves the problem that in the prior art, after the assembly and installation of automotive interior parts, manual inspection is required to check whether the clips are installed in place and the connection strength. This is prone to subjectivity and instability, and it is difficult to detect the problem of loose or missing clips in a timely manner.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0032] The working principle of this utility model is as follows: The two interior trim pieces to be tested, connected by snap fasteners, are placed inside two clamping frames 43. The electric cylinder 44 is activated, pushing the clamping plate 45 downwards. The clamping plate 45 and clamping frames 43 cooperate to securely clamp the interior trim pieces. Then, the drive motor 411 is activated. The drive motor 411, in conjunction with the screw 412, controls two threaded sleeves 413 to move the tension sensor 42 and clamping frames 43 synchronously in opposite directions, thereby applying a gradually increasing separation tension to the snap fastener connection. The tension sensor 42 continuously monitors and records this tension value, transmitting it to the control host 7. The tension stops when it reaches a preset strength value or the snap fastener is pulled out, completing the strength test. For installation testing, the electric push rod 51 is activated, pushing the slide rail 52 downwards. The camera descends to a position close to the snap-fit ​​connection. Then, the servo motor 551 starts, driving the friction wheel 552 to rotate. The friction wheel 552 controls the movement of the sliding sleeve 53, thereby moving the industrial camera 54 to directly above or to the side of the snap-fit ​​connection. When the industrial camera 54 reaches the desired shooting position, the cylinder 553 pushes the pressure plate 554 down, making it press firmly against the surface of the slide rail 52, securely locking the sliding sleeve 53 to prevent shaking during shooting. The industrial camera 54 clearly captures the snap-fit ​​assembly status and transmits the image data to the control host 7. The control host 7 automatically analyzes the image using image processing algorithms to determine if the snap-fit ​​is missing or improperly assembled, overcoming the shortcomings of manual visual inspection which is easily affected by light, angle, and hidden locations, significantly reducing the missed detection rate.
