Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0033] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are used to refer to positions or locations based on the positions or locations shown in the accompanying drawings. These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0034] Reference Figures 1 to 6As shown, the present invention provides a rotary foam laminating mechanism, comprising a turntable module 1 installed in a vertical direction, a turntable drive member 2 connected to the turntable module 1, a plurality of pressure head modules 3 arranged circumferentially and spaced apart on the turntable module 1, and a laminating drive module 4 arranged between the plurality of pressure head modules 3; specifically, the turntable drive member 2 is a motor, which drives the turntable module 1 to rotate counterclockwise, and the pressure head module 3 drives the foam to approach the product to be laminating at a certain rotation speed and direction toward the oblique bottom, so that the foam contacts the surface of the product. In a specific embodiment, the pressure head modules 3 are provided in three numbers, namely the first pressure head module, the second pressure head module, and the third pressure head module. When the first pressure head module is located below the laminating drive module 4, the second pressure head module is located at the foam taking position (waiting for the outside to place the foam on the adsorption head), and the third pressure head module is located at the release film lower position (blowing the release film away by blowing air).

[0035] Among them, the turntable drive 2 is used to drive the turntable module 1 to rotate, so as to drive the multiple pressure head modules 3 to rotate one by one to the bottom of the fitting drive module 4; the pressure head module 3 includes a plurality of adsorption heads 31, and a lifting and lowering pressure rod assembly provided on the top of each adsorption head 31; specifically, a vacuum adsorption hole is provided on the adsorption head 31, which is connected to the vacuum generator. The adsorption head 31 is used to adsorb foam, and the fitting drive module 4 is used to drive the lifting and lowering pressure rod assembly to drive the adsorption head 31 to fit the foam to the surface of the product. The lifting and lowering pressure rod assembly includes a guide pressure rod 32, a guide sleeve 3 movably sleeved on the outer circumference of the guide pressure rod 32, an elastic member movably sleeved on the lower part of the guide pressure rod 32, and a limit plate 34 fixedly provided in the middle of the guide pressure rod 32 and located on the top of the elastic member.

[0036] The bonding drive module 4 includes a pressure plate 41, several pressure sensors 42 located at the bottom of the pressure plate 41, and a bonding drive member 43 connected to the pressure plate 41. Specifically, the bonding drive member 43 is a pneumatic cylinder. The number of pressure sensors 42 is the same as the number of lift rod assemblies, and each pressure sensor 42 is associated with a lift rod assembly. When the bonding drive module 4 is driven downward, the pressure sensors 42 contact the top of the corresponding guide rod.

[0037] The pressure head module 3 also includes a foam clamping plate 37, with a positioning hole defined for each suction head 31. When the laminating drive module 4 drives the lifting and lowering rod assembly to force the suction head 31 downward to press the foam, the suction head 31 can move through the corresponding positioning hole. When foam is placed onto the suction head 31 for loading, the positioning hole allows for rough positioning of the foam. By adjusting the size of the positioning holes, the system can accommodate foams of varying sizes, enhancing versatility.

[0038] The pressure head module 3 also includes a fixing base 38; the foam clamping plate 37 is mounted on the fixing base 38 via an adjustment block 39. The foam clamping plate 37 has a first waist-shaped hole 310 at the end connected to the adjustment block 39, and a second waist-shaped hole 311 at the end connected to the fixing base 38. The length of the first waist-shaped hole 310 is perpendicular to the length of the second waist-shaped hole 311. The first waist-shaped hole 310 and the second waist-shaped hole 311 allow for precise adjustment of the installation position of the foam clamping plate 37, ensuring smooth movement of the foam and secure clamping without damaging the foam.

[0039] The lifting and lowering rod assembly further includes a slide rail 35 connected to one side of the guide rod 32, and a slider 36 slidably connected to the slide rail 35. The slide rail 35 is arranged in a vertical direction and is used to cooperate with the slider 36 to guide the suction head 31 to rise and fall. The top of the slider 36 is fixedly mounted on a fixed base 38.

[0040] The turntable module 1 includes two parallel turntable plates, with the pressure head module 3 connected between the two turntable plates. Furthermore, a rotary foam laminating mechanism also includes a frame 5, one of the turntable plates of the turntable module 1 is mounted on the frame 5, and a laminating drive module 4 is disposed between the two turntable plates and fixed to the frame 5. The laminating drive module 4 cannot rotate with the turntable module 1.

[0041] The foam includes a foam body and a release film adhered to the foam body. When the adsorption head 31 adsorbs the foam, it adsorbs one side of the release film. In one embodiment, the elastic member is a spring.

[0042] The foam bonding process is as follows: the bonding drive part 43 acts to give downward pressure to the guide pressure rod 32, and the pressure sensor 42 responds to the pressure to avoid damaging the product; in the process of the guide pressure rod 32 pressing down, the limit plate 34 descends and compresses the elastic part, and the adsorption head 31 follows and descends to change the distance between the adsorption head 31 and the surface of the product to be bonded, so that the pressure between the foam and the surface of the product to be bonded changes, so that the foam body can better fit the surface of the product.

[0043] The process of tearing off the release film is as follows: the bonding drive module 4 releases the pressure on the guide pressure rod 32. Under the elastic force of the elastic member, the guide pressure rod 32 rebounds and drives the adsorption head 31 to rise. Since the adsorption head 31 sucks the release film at this time, but the foam body has been bonded to the surface of the product, the adsorption head 31 can drive the release film to tear off the foam body.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention. Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention and are not intended to limit the implementation methods of the present invention. For ordinary technicians in the relevant field, various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all implementation methods here.
