Description

Technical Field

[0001] The invention relates to the technical field of automobile exterior trim production, in particular to a spring pressing mechanism that can be guided. Background Art

[0002] Car trims are an important part of car exterior trim. After many trims are re-pressed, bent, sawed, punched, and assembled into ENDCAP, 3M tape is needed to be affixed to the trims, and the trims are attached to the door sheet metal through the 3M tape. When the 3M tape is affixed, constant pressure pressing is required to achieve the best attachment effect, and to ensure that the 3M tape will not debond and fall off on the trims. Door frame trims need to be affixed with 3M tape. In this way, when the trims are attached to the door sheet metal, constant pressure pressing is required to achieve the best bonding effect. The guided spring clamping mechanism in the invention can compress the 3M tape and guide it according to the curvature of the product, so that the 3M tape is attached to the correct position of the product.

[0003] Currently, there is only one 3M tape guide block attached to the trim product. The guide block and the product cross-section are modeled after each other, which can only ensure that the 3M tape can be attached to the trim product. If the 3M tape is not pressed with pressure, it will cause the 3M tape to debond and partially fall off. Summary of the invention

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1 to 8, in the embodiment of the present invention, a spring pressing mechanism that can be guided includes a first mounting plate 5, a first oil-free bushing 17, a discharge screw 20, and a bearing 23. A linear guide rail 4 is installed at the lower end of the first mounting plate 5. A limit block 6 is installed on the left side of the linear guide rail 4 to prevent the slider of the linear guide rail 4 from slipping out. An installation block 3 is installed in front of the linear guide rail 4. A first guide wheel 2 is fixedly installed at the lower end of the installation block 3. The first guide wheel 2 is installed on the installation block 3, and the first guide wheel 2 enables the mechanism to run smoothly on the fixture. Above the right end of the first mounting plate 5, a swing plate 7 is installed. The first mounting plate 5 can float back and forth. A spring pressing mechanism is installed on the swing plate 7. There are oil-free bushings on the connecting block 13 and the swing plate 7. Above the right end of the swing plate 7, a connecting block 13 is installed. The first mounting plate 5 and the swing plate 7 are installed on the linear guide rail 4. A connecting plate 14 is fixedly installed at the rear end of the connecting block 13. A clamp carrier plate 15 is installed on the right side of the connecting plate 14. A quick clamp 16 is installed at the upper end of the clamp carrier plate 15. The quick clamp 16 is installed on the swing plate 7 through an adapter plate. Below the connecting block 13, a fixture surface 12 is installed. An assembly plate 11 is fixedly installed on the right side of the fixture surface 12. A second mounting plate 10 is fixedly installed at the lower end of the assembly plate 11. There is a bushing in the second mounting plate 10. This part of the structure can be stuck on the fixture surface 12, and together with the above mechanism, the entire complete structure can run smoothly along the length direction of the 3M tape, ensuring the accurate position of the 3M tape sticker. At the front end inside the second mounting plate 10, a first spring 8 is installed. Behind the first spring 8, an equal-height screw 9 is installed.

[0026] Among them, the linear guide rail 4 is fixedly connected to the first mounting plate 5. The linear guide rails 4 are equidistantly distributed from front to back at the lower end of the first mounting plate 5. The first guide wheels 2 and the installation blocks 3 are equidistantly distributed from left to right in front of the linear guide rail 4. The quick clamp 16 is fixedly connected to the clamp carrier plate 15. The equal-height screw 9 is located at the rear end inside the second mounting plate 10.

[0027] Among them, a 3M tape guide block 1 is installed below the fixture surface 12. The 3M tape guide block 1 has a guide groove. Designed according to the 3M tape, it can guide and correct the 3M tape entering the pressure wheel 22. Second guide wheels 201 are installed on the left and right sides of the 3M tape guide block 1. A second oil-free bushing 171 is installed below the first oil-free bushing 17. A first guide shaft 18 is installed inside the first oil-free bushing 17 and the second oil-free bushing 171. A second spring 19 is installed on the left side of the first guide shaft 18. The second spring 19 is on the discharge screw 20. The first guide shaft 18 passes through the first oil-free bushing 17 and the second oil-free bushing 171 and is fixed on the pressure wheel 22 mounting plate.

[0028] Among them, a second guiding shaft 21 is installed at the lower end of the unloading screw 20. The second guiding shaft 21 is fixed on the mounting plate of the pressing wheel 22. A pressing wheel 22 is installed inside the 3M tape guiding block 1. A shaft body 24 is installed outside the bearing 23. The first mounting plate 5 and the swing plate 7 are fixedly connected through the bearing 23 and the shaft body 24.

[0029] The working principle of the present invention is as follows: First, the quick clamp 16 drives the mechanism to compress the second spring 19. The elastic force of the second spring 19 is transmitted to the pressing wheel to press the 3M tape. The second guiding wheel 201 can use the profile on the fixture for guiding, so that the whole mechanism can operate along the required trajectory for pasting the 3M tape. The specific working process is as follows: At the beginning, the second spring 19 is in a free state. During the process of pulling the quick clamp 16, the connecting block 13 moves downward along the first guiding shaft 18 and the second guiding shaft 21 through the first oil-free bushing 17 and the second oil-free bushing 171, compressing the second spring 19. The second spring 19 drives the unloading screw 20, the first guiding shaft 18, and the second guiding shaft 21 to move downward together until the pressing wheel 22 presses against the product and stops moving up and down. When the quick clamp 16 continues to move downward, the connecting block 13 will continue to compress the second spring 19. Since the pressing wheel 22 has already contacted the product and stopped moving up and down, when the second spring 19 continues to be compressed, the elastic force is finally transmitted to the pressing wheel 22 through the first guiding shaft 18 and the second guiding shaft 21. In this way, the 3M tape contacted by the pressing wheel 22 obtains a pressing force. To sum up, in view of the above problems and deficiencies, a spring pressing mechanism with guiding is designed. The principle of generating elastic force by spring compression is used to provide pressure during the process of pasting the 3M tape. The guiding mechanism can ensure that the 3M tape is pasted at the position required by the trim product, with convenient operation, high stability, and low cost.

[0030] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
