Description

Technical Field

[0001] This utility model relates to the field of automotive decorative parts technology, and in particular to an automatic pressing device for bright decorative strips. Background Technology

[0002] Bright trim strips, as an indispensable component of automotive exterior decoration, are widely used in areas such as window frames, body waistlines, and door seams. They not only serve an aesthetic purpose but also provide sealing, concealing structural seams, and enhancing the overall quality of the vehicle. During automotive manufacturing, the installation precision of bright trim strips directly affects the consistency of the vehicle's appearance and its sealing performance. Therefore, the installation process places high demands on positioning accuracy, clamping force distribution, and ease of operation. With increasingly complex vehicle designs, the shape, installation position, and clamping path of bright trim strips are becoming more diverse and asymmetrical. Improving clamping efficiency, controlling clamping quality, and ensuring product consistency have become urgent problems to be solved in automotive assembly processes.

[0003] In traditional assembly processes, the pressing of bright trim strips is mostly done manually, using fixed molds or simple pressing tools. The common practice is to initially position the trim strip, then use manual tools such as pressure rollers, rubber mallets, or specialized trim strip pressers to apply pressure segment by segment along the strip's extension direction, pressing it into the mounting groove or against the vehicle body surface. To aid positioning, some tooling tables are equipped with adjustable guide rails or limit blocks to align the trim strip with the vehicle body edge, while mechanical clamps control the pressing path and angle. However, throughout the process, the pressing force relies on manual control. Operators must repeatedly adjust hand force, pressing speed, and position alignment, which can easily lead to problems such as poor compaction, trim strip warping, or surface scratches. This is especially true when installing multi-segment irregularly shaped trim strips, where accuracy is difficult to guarantee, and the workload is relatively high.

[0004] Current methods for tightening bright trim strips primarily rely on manual operation, which suffers from uneven tightening force, inaccurate positioning, misalignment, or warping, making it difficult to guarantee installation quality. Furthermore, manual operation is inefficient, labor-intensive, and highly dependent on operator experience, easily leading to inconsistent assembly quality. These problems are particularly pronounced in mass production and are no longer sufficient to meet the efficiency and consistency requirements of modern automobile manufacturing.

The extrusion plate 13 is the component that directly contacts the bright trim strip. Under hydraulic drive, it completes the uniform pressing of the bright trim strip. The inner wall of the extrusion plate 13 is slidably connected to the limit rod 8.

[0028] Reference Figures 1-5The electric slide rail 3 has a worktable 2 fixedly connected to its outer wall. The worktable 2 serves as a platform for placing the car window glass and the parts to be assembled, providing a basic support surface for the pressing operation. It also integrates a limiting mechanism. A threaded rod 15 is threadedly connected to the inner wall of the worktable 2, and a knob 16 is threadedly connected to the outer wall of the threaded rod 15. A slider 17 is attached to the outer wall of the knob 16. The slider 17 rotates with the knob 16 to generate horizontal displacement, pressing and fixing the object. A limiting rod 18 is slidably connected to the inner wall of the slider 17. A fixing block 20 is fixedly connected to the outer wall of the limiting rod 18. A spring 19 is sleeved on the outer wall of the limiting rod 18, providing elastic pressing force so that the slider 17 can press the object. A bracket 1 is fixedly connected to the lower surface of the worktable 2. One end of the limiting rod 8 is fixedly connected to the lower surface of the connecting plate 6. The inner wall of the slider 17 is slidably connected to the outer wall of the threaded rod 15. The threaded rod 15 is set on the inner wall of the worktable 2 and is used to drive the slider 2 17 to move horizontally by rotation to realize the glass limit adjustment. The outer wall of the fixing block 20 is fixedly connected to the lower surface of the worktable 2. One end of the spring 19 is fixedly connected to the outer wall of the slider 2 17, and the other end of the spring 19 is fixedly connected to the outer wall of the fixing block 20. The fixing block 20 serves as the fixing end of the spring 19, fixing one end of it to the worktable 2 to ensure that the spring 19 is stably stressed. The outer wall of the connecting rod 19 is rotatably connected to the connecting rod 3 12. One end of the limiting rod 18 is fixedly connected to the upper surface of the worktable 2. The extrusion plate 13 is set below the connecting plate 6. The connecting plate 6 is installed on the top of the column 5 and is used to support the hydraulic cylinder 7 and the multi-link extrusion mechanism as a whole. It is the mounting base of the extrusion assembly. The fixing block 10 is set below the connecting plate 6, the limiting rod 2 18 is set below the worktable 2, and the knob 16 is set above the limiting rod 2 18.

[0029] Working principle: When an automatic trim strip pressing device is needed, firstly, the car glass or car parts are manually placed on the worktable 2. Then, the trim strip to be installed is pre-positioned on the car body. After preliminary positioning, when the trim strip needs to be pressed, the inner wall of the worktable 2 is equipped with an electric slide rail 3. A slider 4 slides on the inner wall of the electric slide rail 3. The upper surface of the slider 4 has a connecting column 5. The top of the column 5 is equipped with a connecting plate 6 to support the pressing component. The output end of the hydraulic cylinder 7 is connected to the fixing block 10. It forms a connection through the connecting rod 2 11, connecting rod 1 9 and connecting rod 3 12. The multi-link extrusion mechanism ultimately drives the extrusion plate 13 to move downward, thereby pressing the bright trim strip. The inner wall of the extrusion plate 13 is slidably connected to the limit rod 8, which is used to control the pressing depth and position accuracy. During extrusion, the electric slide rail 3 drives the slider 4 to move the extrusion assembly to the designated position. The hydraulic cylinder 7 is activated to push the fixed block 10 downward, which in turn drives the multi-link system to move, so that the extrusion plate 13 vertically presses the bright trim strip. The limit rod 8 provides stroke limit to ensure pressing consistency. The whole process realizes automated operation, reduces human error, and effectively improves the assembly quality and assembly efficiency of the bright trim strip.

[0030] Furthermore, to prevent poor adhesion between the bright trim strip and the glass due to positional misalignment or vibration during assembly, the inner wall of the worktable 2 is provided with a threaded rod 15, which is threadedly connected to a knob 16. The outer wall of the knob 16 is fitted with a slider 17, and the inner wall of the slider 17 is slidably connected to a limiting rod 18. The outer wall of the limiting rod 18 is provided with a spring 19 and is fixedly connected to a fixing block 20. The limiting rod 18 is used to contact and limit the edge of the glass. During operation, adjusting the knob 16 can cause the slider 17 to move horizontally under the action of the threaded rod 15, thereby compressing the spring 19 and limiting the slider 17 through the limiting rod 18, allowing it to slide horizontally. Through this structure, the window glass can be effectively limited and fixed before assembly, preventing it from shifting due to external force when pressing the bright trim strip, ensuring the stability and safety of the pressing process, and improving the overall consistency and reliability of the vehicle assembly.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
