[0027] See also Figure 1 As shown, this embodiment provides a car roof sunroof R corner hemming mechanism, including a lower mold support surface 1, a lifting base plate 2, a driving assembly and an hemming push mold 3, wherein:

[0028] The lower mold support profile 1 is used to position the canopy product 16 and to support the inner edge of the skylight R angle of the canopy product 16;

[0029] The lifting base plate 2 is located on one side of the lower mold supporting surface 1 and can be lifted and lowered relative to the lower mold supporting surface 1;

[0030] The driving assembly is arranged on the lifting base plate 2, and the driving assembly includes a push plate 4 and a connecting plate 5 that can reciprocate relative to the lower mold support surface 1. An elastic member is arranged between the push plate 4 and the connecting plate 5, and the elastic member applies a force to the connecting plate 5 toward the push plate 4;

[0031] The edge-wrapping push die 3 is fixed on the connecting plate 5 and is used to contact the outer edge of the skylight R corner of the roof product 16 and cooperate with the lower die support profile 1 to wrap the skylight R corner of the roof product 16.

[0032] Thus, the edge-wrapping mold 3 can be extended and retracted according to the adaptability of the roof product 16 surface through the elastic member, and the lifting base plate 2 and the driving assembly can be coordinated to stretch the fabric evenly and achieve a better edge-wrapping effect.

[0033] Optionally, the elastic member includes a spring 6, a guide screw 7 is provided on the connecting plate 5, the guide screw 7 is fitted with an adjusting nut 8 after passing through the push plate 4, and the spring 6 is sleeved on the guide screw 7 and located between the push plate 4 and the adjusting nut 8.

[0034] During the hemming process, the lifting base plate 2 descends, driving the hemming pusher 3 to move downward along the roof product 16, overcoming the elastic force of the spring 6. Simultaneously, the spring 6 is compressed, forcing the hemming pusher 3 to adhere tightly to the roof product 16, ensuring hemming quality. This flexible contact method, compared to conventional hard contact methods, causes less damage to the surface and fabric of the roof product 16, resulting in a better hemming effect.

[0035] Furthermore, the position of the adjusting nut 8 on the guide screw 7 is adjustable to change the elastic force of the spring 6, and thus the force acting on the connecting plate 5 is adjustable to meet different hemming requirements.

[0036] Optionally, a guide member is provided between the lifting base plate 2 and the connecting plate 5 , and the guide member is used to limit the movement of the connecting plate 5 to ensure the accurate reciprocating movement of the hemming push die 3 .

[0037] Specifically, the guide member includes a slide rail 9 fixed to the lifting base plate 2 and a slider 10 fixed to the bottom surface of the connecting plate 5. The slide rail 9 and the slider 10 are in sliding engagement with each other. Alternatively, the slide rail 9 and the slider 10 can be replaced by a linear bearing and an optical axis, etc., as long as the linear guide function is met.

[0038] Optionally, the drive assembly further includes a horizontal cylinder 11, which is fixed to the lifting base plate 2, with the output rod of the horizontal cylinder 11 facing the lower mold support surface 1, and the push plate 4 is fixed to the output rod of the horizontal cylinder 11. Alternatively, the horizontal cylinder 11 can also be replaced by an electric cylinder, an oil cylinder, an electric push rod, etc., as long as the telescopic function is met.

[0039] Furthermore, a stroke adjustment plate 12 is provided on the cylinder body of the horizontal cylinder 11. A stroke screw 13, which is parallel to the output rod of the horizontal cylinder 11, is mounted on the stroke adjustment plate 12. The stroke screw 13 passes through the push plate 4 and is equipped with two sets of limit nuts 14 for limiting the travel of the push plate 4. Thus, by adjusting the travel of the push plate 4 using the limit nuts 14 or adjusting the compression of the spring 6 using the adjustment nut 8, the gap between the hemming push die 3 and the lower die support surface 1 can be adjusted to meet the hemming requirements of different specifications of canopy products 16 and fabrics of different thicknesses.

[0040] Optionally, a follower plate 15 is provided on the push plate 4 to limit the connecting plate 5, thereby ensuring the movement accuracy of the connecting plate 5 so that the connecting plate 5 can only move axially along the guide screw 7 relative to the push plate 4.

[0041] Optionally, a lifting cylinder is provided below the lifting base plate 2 , and an output rod of the lifting cylinder is fixed to the bottom surface of the lifting base plate 2 .

[0042] Optionally, the surface of the lower mold support profile 1 in contact with the canopy product 16 and the surface of the edge push mold 3 in contact with the canopy product 16 are respectively designed to adapt to the surface shape of the canopy product 16 to ensure the supporting effect of the canopy product 16 and the covering effect of the fabric.

[0043] Process flow: 1) Place the canopy product 16 on the lower mold support surface 1; 2) The horizontal cylinder 11 pushes the edge-wrapping push die 3 through the push plate 4 and the connecting plate 5 until the active surface of the edge-wrapping push die 3 is just located at or slightly exceeds the outer edge of the skylight R angle of the canopy product 16; 3) The lifting cylinder drives the lifting base plate 2 to gradually descend, the spring 6 on the guide screw 7 is gradually compressed, and the edge-wrapping push die 3 gradually descends close to the outer edge of the skylight R angle of the canopy product 16 until the edge wrapping is completed.

[0044] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
