The application provides a cladding device 2 for cladding a flexible skin 12 on a frame 11 surface to obtain a trim piece. As shown in fig. 6, the cladding apparatus 2 includes a flexible laminate layer 21, an air chamber 22, and an air-inflating unit 23. The flexible pressing layer 21 is adapted to deform to conform to the contour of the frame 11, the flexible pressing layer 21 being disposed within the air chamber 22 to divide the air chamber 22 into a first air chamber 221 and a second air chamber 222 isolated from each other; the first air cavity 221 is adapted to house the frame 11 and the epidermis 12; the second air cavity 222 is a closed cavity, the inflation unit 23 is used for inflating the second air cavity 222, and the flexible pressing layer 21 deforms towards the first air cavity 221 when the second air cavity 222 is inflated, so that the flexible pressing layer 21 pushes the skin 12 to deform along the contour of the frame 11 and cover the surface of the frame 11.

It is worth mentioning that the surface of the frame 11 and/or the surface of the skin 12 are/is provided with an adhesive in advance, so that the skin 12 is adhered to the frame 11 when the skin 12 is coated on the surface of the frame 11.

The working principle of the cladding device 2 of the present application is as follows: the inflation unit 23 inflates air into the second air cavity 222, the air pressure in the second air cavity 222 increases, which causes the air pressure on the two sides of the flexible pressing layer 21 to be unbalanced, so that the flexible pressing layer 21 deforms under the action of the air pressure on one side, the flexible pressing layer 21 continuously expands in the deformation process, the second air cavity 222 continuously expands, the first air cavity 221 continuously contracts, as shown in fig. 6-9, as the frame 11 is arranged in the first air cavity 221, the flexible pressing layer 21 deforms along the profile of the frame 11 in the process of being pressed towards the first air cavity 221, and as the flexible skin 12 is arranged between the flexible pressing layer 21 and the frame 11, the skin 12 is also pressed towards the frame 11 along with the flexible pressing layer 21, so as to be attached to the surface of the frame 11 along the profile of the frame 11, and thus the skin 12 covers the frame 11 is achieved.

The coating equipment 2 not only can coat the front surface of the frame 11 by the surface skin 12, but also can coat the side surface of the frame 11 by the surface skin 12, namely, the edge of the frame 11 is also coated. During machining, the skin 12 is arranged between the flexible pressing layer 21 and the frame 11, and outside the frame 11 extending the edge of the skin 12, when the flexible pressing layer 21 deforms, the flexible pressing layer 21 first contacts with the skin 12, and applies a force to the skin 12 to deform in the direction of the frame 11, so that the skin 12 is attached to one side surface of the frame 11, the inflation unit 23 continuously inflates the second air cavity 222, the flexible pressing layer 21 is continuously pressed in the direction of the frame 11 and adapts to the contour of the frame 11, so that the flexible pressing layer 21 pushes the skin 12 extending outside the frame 11 to be folded inwards and attached to the side surface of the frame 11, and when the flexible pressing layer 21 further deforms to the other side of the frame 11, the skin 12 is also folded inwards and attached to the other side surface of the frame 11.

It is worth mentioning that, in the actual processing process, the flexible pressing layer 21 with corresponding size and shape can be arranged according to the size and shape of the region to be coated of the frame 11, so that after the flexible pressing layer 21 deforms to adapt to the contour of the frame 11, the region to be coated of the frame 11 can be at least wrapped, and the flexible pressing layer 21 can ensure that the skin 12 can be sufficiently attached to the region to be coated of the frame 11.

The application adopts the flexible laminated layer to realize the cladding of the surface to the frame, which is beneficial to simplifying the structure of the equipment, reducing the cost of the equipment and reducing the volume of the equipment.

Further, the edge of the flexible pressing layer 21 is connected to the air chamber 22 in a sealing manner, so that the first air cavity 221 and the second air cavity 222 are isolated by the flexible pressing layer 21 in a sealing manner, and the first air cavity 221 and the second air cavity 222 are not communicated with each other.

Further, the inner wall of the air chamber 22 is rigid, so that when the flexible pressing layer 21 deforms, the flexible pressing layer is limited by the air chamber 22 and can only deform into the air chamber 22, and the flexible pressing layer 21 can effectively wrap the frame 11.

In the present application, the first air cavity 221 mainly functions to compress or control the deformation direction of the flexible pressing layer 21 by inflating the second air cavity 222 to provide the power required for the wrapping, so that the flexible pressing layer 21 is adapted to the contour deformation of the frame 11.

In a preferred embodiment, the flexible pressing layer 21 is a flexible material having elasticity, so that the flexible pressing layer 21 is elastically deformed to conform to the contour of the frame 11 when deformed in the direction of the first air chamber 221. The material of the flexible laminated layer 21 may be natural rubber or various synthetic rubbers, or may be other flexible materials having elasticity. In this embodiment, the original shape of the flexible laminate layer 21 need not be fully adapted to the contour of the frame 11, but may be adapted to the contour of the frame 11 by virtue of the elastic deformation capability of the flexible laminate layer 21. For example, the original shape of the flexible laminate layer 21 may be a plane, as shown in fig. 10, when the flexible laminate layer 21 is pressed toward the first air cavity 221 and elastically deformed, the flexible laminate layer 21 first contacts the skin 12, as shown in fig. 11, since the skin 12 is also flexible, the flexible laminate layer 21 pushes the skin 12 to deform together, and when the skin 12 is attached to the frame 11, the rigid frame 11 makes the flexible laminate layer 21 deform continuously only along the contour of the frame 11, so that the flexible laminate layer 21 pushes the skin 12 to wrap along the contour of the frame 11, as shown in fig. 12.

In the above embodiment, the flexible pressing layer 21 can be adaptive to the profile of the frame 11, so that the coating device of the present application can be applied to coating of frames 11 with different profiles, thereby greatly improving the universality of the coating device, being beneficial to reducing the cost of the coating device, and saving the cost of a manufacturer.

In another preferred embodiment, the flexible pressing layer 21 has a pressing portion capable of adapting to the contour of the frame 11, that is, the shape of the pressing portion is consistent with the contour of the frame 11, the flexible pressing layer 21 is disposed in the air chamber 22 in a folded state before the second air chamber 222 is inflated, as shown in fig. 13, the flexible pressing layer 21 is deformed from the folded state to an unfolded state when the second air chamber 222 is inflated, so that the shape of the pressing portion fits the contour of the frame 11, thereby wrapping the frame 11, as shown in fig. 14, and the flexible pressing layer 21 is adapted to press the skin 12 against the frame 11 and wrap the surface of the frame 11 during the process of wrapping the frame 11 with the flexible pressing layer 21. It should be noted that, in this embodiment, the flexible pressing layer 21 may have a certain elasticity or may be non-elastic, and the original shape of the flexible pressing layer 21 has a pressing portion adapted to the contour of the frame 11, so that the flexible pressing layer 21 can fully wrap the frame 11 after being unfolded, especially at the turning angle with a large change in angle, and the flexible pressing layer 21 can fully wrap the turning angle after being unfolded, thereby ensuring that the skin 12 is fully contacted with the frame 11 in the area of the turning angle.

In the above embodiment, the flexible pressing layer 21 may be provided with an original shape of the flexible pressing layer 21 according to the contour shape of the frame 11 to be wrapped, so that the flexible pressing layer 21 can sufficiently adapt to the outer shape of the frame 11 after being unfolded, and the skin 12 is sufficiently contacted with the frame 11, thereby avoiding an unbonded area between the skin 12 and the frame 11.

Further, the cladding apparatus 2 comprises a first shell 25 and a second shell 26 for defining the air chamber 22, the first shell 25 being detachably connected with the second shell 26, the edge of the flexible laminate layer 21 being sealingly connected with the second shell 26, as shown in fig. 4. When the first shell 25 is separated from the second shell 26, the frame 11 and the skin 12 may be disposed in the first shell 25 or the second shell 26, as shown in fig. 5, and after the frame 11 and the skin 12 are disposed, the first shell 25 and the second shell 26 are combined and connected, as shown in fig. 6, so that the frame 11 and the skin 12 are disposed in the air chamber 22.

Further, the cladding apparatus 2 further comprises a support platform 223 arranged on the second shell 26, as shown in fig. 4, the support platform 223 being used for supporting the skin 12 and the frame 11 above the flexible bonding layer 21, the support platform 223 having a channel 2230 at an edge thereof for allowing the flexible bonding layer 21 to pass through, such that the flexible bonding layer 21 passes through the channel 2230 to contact the skin 12 on the support platform 223 when deformed. It is worth mentioning that when the wrapping is performed, the skin 12 is located between the frame 11 and the support platform 223, and the edge of the skin 12 extends above the channel 2230, and the edge of the frame 11 does not cover or does not cover the channel 2230 completely, as shown in fig. 6, so that the flexible laminate layer 21 acts directly on the skin 12 after passing through the channel 2230 and pushes the skin 12 to turn towards the frame 11, as shown in fig. 8.

Further, the channel 2230 is located inside the edge of the support platform 223, i.e. the channel 2230 is formed on the support platform 223, and the skin 12 can completely cover the channel 2230, so that the flexible laminate layer 21 can sufficiently act on the skin 12 when passing through the channel 2230.

In other embodiments, the channel 2230 may also be outboard of the edges of the support platform 223, i.e., the channel 2230 is defined by the edges of the support platform 223 in combination with the inner walls of the plenum 22.

Further, the cladding apparatus 2 further comprises a frame fastening unit 24 mounted on the first housing 25, the frame fastening unit 24 being for holding the frame 11 at a preset position. As shown in fig. 5, before the covering, the first shell 25 is separated from the second shell 26, the frame 11 is mounted on the first shell 25 by the frame fastening unit 24 while the skin 12 is disposed on the support platform 223 of the second shell 26, and then the first shell 25 and the second shell 26 are combined and connected to form the air chamber 22 such that the skin 12 is sandwiched between the frame 11 and the support platform 223, as shown in fig. 6.

In some embodiments, the frame fastening unit 24 is a clamping mechanism 24a, and the clamping mechanism 24a clamps the non-covered region of the frame 11 to fix the frame 11. In other embodiments, the frame fastening unit 24 is a negative pressure adsorption mechanism 24b, and the negative pressure adsorption mechanism 24b adsorbs a non-coating region of the frame 11 to fix the frame 11.

It is worth mentioning that the frame fastening unit 24 may include several clamping mechanisms 24a and several negative pressure adsorption mechanisms 24b at the same time to ensure that the frame 11 is stably held at a fixed position.

Further, as shown in fig. 4, the first housing 25 has a first cavity 250, the second housing 26 has a second cavity 260, when the first housing 25 is connected to the second housing 26, the first cavity 250 and the second cavity 260 are communicated to form the air chamber 22, the frame fastening unit 24 is disposed in the first cavity 250, the flexible pressing layer 21 is disposed in the second cavity 260, and the support platform 223 is disposed above the second cavity 260.

In some embodiments, the draping device 2 comprises at least one closed air bag 21a, the second air cavity 222 is formed in the air bag 21a, the inflation unit 23 is used for inflating the air bag 21a, and the area of the air bag 21a facing the epidermis 12 is the flexible press layer 21. Preferably, the number of the inflator units 23 corresponds to the number of the airbags 21a, and each airbag 21a is individually inflated by one inflator unit 23. The space of the air chamber 22 outside the air bag 21a is the first air chamber 221. The bladder 21a may be elastic or inelastic.

In one embodiment, the airbag 21a is an elastic airbag, and when the inflating unit 23 inflates the airbag 21a, the airbag 21a is elastically deformed to expand. As shown in fig. 7, the area of the bladder 21a facing the skin 12 (i.e., the flexible laminate layer 21) is inflated to press against the support platform 223 and push the edges of the skin 12 upward after passing through the channel 2230, as shown in fig. 8, and then the bladder 21a continues to inflate to fill the first air cavity 221 and push the skin 12 everted over the surface of the frame 11, as shown in fig. 9.

In another embodiment, the bladder 21a is a non-elastic bladder, and the region of the bladder 21a facing the skin 12 (i.e., the flexible laminate layer 21) has a stitching capable of conforming to the contour of the frame 11. As shown in fig. 13 and 14, when the inflation unit 23 inflates the airbag 21a, the airbag 21a deforms from the folded state to the deployed state, and during the gradual deployment of the airbag 21a, the airbag firstly passes through the channel 2230 of the support platform 223 to push the edge of the skin 12 to turn upwards, and then the airbag continues to deploy according to the contour of the frame 11, and continuously pushes the skin 12 to turn inwards and cover the surface of the frame 11, as shown in fig. 14.

The number of the air bags 21a can be selected according to actual conditions, and if the outline shape of the frame 11 is relatively regular, the whole frame 11 can be coated with the skin 12 by using only one integral air bag 21a, as shown in fig. 6-9, which is beneficial to simplifying equipment and reducing equipment cost. If the contour of the frame 11 is irregular, a plurality of air bags 21a may be provided to wrap different areas, as shown in fig. 13-16, which is advantageous to improve the wrapping effect and ensure that the skin 12 is in full contact with the frame 11.

As shown in the embodiment of fig. 1-4, the draping device comprises a plurality of air bags 21a, the flexible laminate layer 21 on each air bag 21a being adapted to adapt to a part of the contour of the frame 11, as shown in fig. 4, so that the plurality of air bags 21a co-act to achieve complete draping of the frame 11 by the skin 12.

It should be noted that when there are a plurality of air bags 21a, different air bags 21a can be wrapped on different surfaces by controlling the time for inflating each air bag 21a, as shown in fig. 15 and 16, the air bag 21a disposed below the frame 11 can be inflated first, and when the skin 12 is turned over to the upper surface of the frame 11, the air bag 21a disposed above the frame 11 is inflated, so that the skin 12 is in full contact with the upper surface of the frame 11.

In one embodiment, the cladding apparatus 2 includes an air chamber 22 corresponding to each air bag 21 a. The air chambers 22 may be connected to each other or may be independent of each other.

Further, as shown in fig. 3, the second housing 26 has a plurality of second cavities 260 independent of each other, and each airbag 21a is disposed in one of the second cavities 260 so that the respective airbags 21a do not interfere with each other when inflated. It should be noted that the second cavities 260 may be independent from each other or may be connected to each other, which is not limited in this application.

Preferably, each of the second cavities 260 is sequentially disposed along the edge of the support platform 223, as shown in fig. 3, such that the air cells 21a located in the second cavities 260 are sequentially disposed along the edge of the support platform 223.

Preferably, the second shell 26 has a U-shaped second cavity 260 corresponding to a corner region of the frame 11 and a U-shaped bladder 21a, the U-shaped bladder 21a is disposed in the U-shaped second cavity 260, and when the U-shaped bladder 21a is inflated, the corner region of the frame 11 can be completely wrapped such that the skin 12 is in sufficient contact with the frame 11 at the corner.

In one embodiment, a set of air bags 21a for frame hemming is provided, including a plurality of strip-shaped air bags 21a-1 and a pair of U-shaped air bags 21a-2, the pair of U-shaped air bags 21a-2 is adapted to the contour of the corners on both sides of the frame 11, and the plurality of strip-shaped air bags 21a-1 is adapted to the contour of the frame 11 between the corners, as shown in FIG. 3.

It is worth mentioning that the contour of the frame 11 to be covered between two corners is usually not changed by a large angle, even if there is a slightly bent region, the contour of the frame 11 can be better adapted by providing a plurality of strip-shaped airbags 21a-1, while the contour of the frame 11 can be better adapted by providing a U-shaped airbag 21a-2 with a large angle change at the corner of the frame 11.

Further, the airbag 21a has an inflation connector 213 thereon, and the inflation connector 213 is used for quickly connecting the airbag 21a with the inflation unit 23. The second housing 26 has a through hole corresponding to the air charging connector 213 such that the air charging connector 213 is adapted to extend to the outside of the second housing 26 through the through hole to facilitate connection with the air charging unit 23.

The film 21b may be elastic or inelastic. If the membrane 21b is an elastic membrane, it deforms elastically and adapts to the contour of the frame 11 when deformed. If the film 21b is a non-elastic film, the film 21b has a pressing portion capable of conforming to the contour of the frame 11, the film 21b is disposed in a folded state before the second air chamber 222 is inflated, and the film 21b is deformed from the folded state to an unfolded state when the second air chamber 222 is inflated, so that the pressing portion of the film 21b wraps the frame 11.
